1. MINERAL PROGRAMME

1.1. Summary World market prices for some mineral commodities have tended to increase recently caused by political turmoil and economic policies in some countries and this has triggered an increase in mineral exploration activities in Indonesia. Various local and foreign companies continue to engage in intensive exploration activity. The Miwah project in , Belu Manganese Project in the Belu of West , Lakuwahi project on Romang Island, the Randu Kuning project in Wonogiri Regency, Suruh and Timahan prospect, Trenggalek Regency, Soro Arc Exploration in East Sumbawa, Tumpangpitu project, and the Tembang Gold and Silver Project in Central Sumatera are several projects that are still ongoing and are expected to find new resources of metallic minerals in Indonesia. ’s policy of termination of rare earth exports has increased the price of these raw materials for worldwide high technology usage. These resulted in a shift in demand for mineral commodities which also affect mining activities in Indonesia. The Geological Agency of Indonesia is actively conducting REE exploration in anticipation of providing preliminary REE exploration data and information. Resources and reserves of metallic minerals continue to change with exploration and production activities of existing companies. Of these, Grasberg, Batuhijau, Gosowong, Pongkor is still the largest contributor of resources, reserves and production as well as gold and or copper in Indonesia. While Soroako, Pomalaa, Weda Bay, P. Gag and Tanjung Buli is the largest contributor of resources and reserves of nickel. Total resources and reserves of some metallic minerals in Indonesia as atl 2011are described in table 1.

CCOP Member Country Report: INDONESIA 1 1.2. Annual Review of Individual Technical Activities During mid-late 2010 until mid-early 2012, The Geological Agency as a government institution in charge of compiling an inventory of mineral resources and exploration in order to provide preliminary data, has been conducting an investigation in some selected areas with different types of mineral commodities such as lead, gold, bauxite, iron sand, ree. nickel, and copper. To implement the cooperative project of “Geochemical Mapping and Mineral Resources Assessment Research in Island, Indonesia” between the China Geological Survey, Ministry of Land and Resources of the People’s Republic of China and the Geological Agency of Indonesia, the Ministry of Energy and Mineral Resources of Indonesia, a 1st phase was carried out during 2010 – 2011 in West Sumatera Province. The metallic mineral inventory in Sangihe Islands and Sitaro Islands, North found several mineralization indications; haematite at Kawaluso, malachite mineralization at Lipang, advanced argillic alteration, piritization and malachite staining at northern Sangihe and Nusa Tabukan Islands, argillic alteration containing 171 ppb Au at Beeng Darat and Beeng Laut and gold and cinnabar in pan concentrate at Biaro island and Siau island. Base on secondary data, gold resources were found at Binebase-Bawone and iron sand at Kaluare- Kalasuge, Naha-Kaluare and Sensong-Lesahe In Bukit Batu Balai and Takalong, Sekayam District, Sanggau Regency, 2 vein type mineralization zones were discovered : gold mineralization (Au 17,620 ppb from rock sample) in barite and quartz vein, copper mineralization(Cu 47,037 ppm from rock sample) in quartz vein. Gold, cassiterite and garnet are found in pan concentrates from several locations. A drilling program at Blitar Regency found chalcopyrite filled cracks at interval 430,40 – 430,55 m and 450,20 – 450,80 m. Field obeservations at area indicated nickel, chrome metallic mineralisation that is prospective to be developed,. Mineralization indications in Pronojiwohaharu dan Lewa districts, East Regency were observed from float of quartz veins containing pyrite, chacopyrite, azurite and gold in pan concentrates at 3 locations. The mineralization is interpreted to result from hydrothermal processes in andesitic-basaltic volcanic rock. In Moyo hulu, Plampang and Tarano dsitricts, Sumbawa Regency, alteration and mineralization occurred in Tertiary volcanic rocks and some gold mineralization was mined by local people. Mineralization indications are associated with quartz veins with vuggy texture, but not associated with copper. REE exploration at Sosortolong area, North Tapanuli, estimated REE resources at 3 block areas, to total 4.426.115,4 tonnes. REE in soil samples have been analysed and significant results for Ce, La, and Pr were indicated, respectively (600 ppm – 1400 ppm), (400 – 1000 ppm) and (600 ppm – 1400 ppm). Iron sand exploration at West area resulted total resources of 170.758,0795 ton concentrate containing 53,34 % Fe total and 12,73 %, TiO2 from 4 block area being estimated. Bauxite exploration at Sanggau, West resulted indicated resources of 3 86.632 m containing average Al2O3 51,17% Fe2O3 11,6%, SiO2 5,91% and TiO2 1,49% at 3 Engkitan-Seputau area and 1.370.365 m containing average Al2O3 52,63% Fe2O3 9,76%, SiO2 3,57% and TiO2 1,32% at Bukit Darwin area.

2. ENERGY PROGRAMME 2.1. HYDROCARBON 2.1.1. Summary Indonesia, like most developing countries, is a fossil-fuel driven country. The primary energy source fueling Indonesia’s economy continues to be oil at 50% in 2011. Coal consumption is becoming more widespread accounting for 24% as the second most consumed fuel, surpassing gas at 20%. Coal will be the primary domestic energy source, particularly to fuel new power generation capacity. Hydro and other renewable sources share 6% in the total energy mix. Indonesia’s crude oil production has been declining since 1998, due to maturation of the country’s largest oil fields and failure to develop new, comparable resources. Oil production of existing fields naturally declines by approximately 12% per year. By making continuousl efforts, this production decline could be controlled and limited to about 3% per year. According to the Directorat General Oil and Gas, Ministry of Energy and Mineral Resources, the total of Indonesian oil reserves in 2011 was 7,732 million barrels, consisting of proven reserves of 4,040 million barrels and potential reserves of 3,693 million barrels. With the total production of 339 million barrel a year in 2010, this means that the proven reserves are sufficient for only about 12 years if additional proven reserves are not acquired. Additional oil reserves could be found through the successful implementation of EOR technologies in potential fields and by exploration drilling in hydrocarbon basins which are not yet explored. In contrast with oil production, Indonesia’s gas production has been increasing since 2007 and is still expected to grow further in the coming years. The increase of gas production is prioritized for domestic needs. The total of Indonesian gas reserves in 2010 amounted to 153 trillion cubic feet, comprised of proven reserves 105 trillion cubic feet and potential reserves 48 trillion cubic feet. With the total production 3196 billion cubic feet a year in 2010, it means that the proven reserves will last for only about 33 years if there are no new discoveries. Driven by the fact that the reserves replacement ratios (RRR) for oil and gas are only 36% and 41% respectively, while domestic consumption does not show a significant decrease, efforts have been prompted to develop unconventional hydrocarbon resources in addition to renewable energy resources. In recent years, acceptance of coal bed methane (CBM) as an alternative natural gas supply is evidenced by the increasing number of operating area licenses issued by the government. The first gas production for electricity from CBM is targeted for the end of 2011. Included in unconventional gas is shale-gas. Based on the results of temporary identification, Indonesian shale-gas resources are in four regions of Sumatra, Java,

CCOP Member Country Report: INDONESIA 3 Kalimantan and . The government began compiling the rules of law to facilitate the development of this resource. During the period of this report, Indonesia has carried out collaboration with worldwide organizations to investigate the potential for deployment and development of Carbon Capture and Storage (CCS) in Indonesia, which offers great potential for reducing CO2 emissions from large point source emitters, such as coal-fired power plants and oil and gas processing plants. 2.1.2. Annual Review of Individual Technical Activities Indonesian oil and gas reserves status on 1 January 2010, taken as the aggregate of proven and potential reserves is 7,764 million barrel of oil and 157 trillion cubic feet of gas. Almost all of the oil fields in Indonesia have been at the highest peak production and now are in a decreasing condition. To increase the oil production, the government is trying increasing oil recovery from brown fields. Some efforts which are being carried out include improving production tools reliability to decrease unplanned shutdown, increasing operational efficiency, and optimizing production facility, infill drilling, and EOR implementation. To accelerate development of EOR, the Executive Agency for upstream Oil and Gas Business Activities (BPMIGAS) asked all Production Sharing Contract Contractor(s) (KKKS), who have been producing, to implement EOR. For example, Chevron Pacific Indonesia will process Minas Field for chemicals, Medco will implement EOR in Kaji- Semoga Field, and also Pertamina E&P in Tanjung Field. The Minas and Kaji chemical pilot tests will be carried out within this year. The success of EOR technology implementation is quite considerable remembering that recently the remaining oil in-place in Indonesia was still about 44,938 million barrels. If EOR succeeds in increasing the recovery factor by 10 %, then there will be additional reserves of about 4, 494 million barrels. This addition is a little more than the 2011 national proven oil reserves. Indonesia’s gas production has grown at an average annual rate of about 1.5% over the last decade. In 2011, Indonesia produced 3.1 trillion cubic feet of gas. An increasingly large majority of Indonesia’s gas production has come from non-associated fields in recent years, with associated gas accounting for about 14% of gross production in 2011. The most significant areas for current natural gas production are: • ’s offshore fields, particularly the Mahakam PSCs operated by Total • South Sumatera, particularly the onshore Corridor PSC operated by Conoco Philips • South Natuna Sea, offshore Block B operated by Conoco Philips • Papu, the offshore Muturai and Berau PSCs operated by BP The development of gas dominates the oil and gas projects in Indonesia during the period 2012 through 2014. The production design capacity for those projects is 1,068 million cubic feet of gas per day, 175,150 barrel of oil per day. Those projects are listed in Table 2.

In finding oil and gas reserves, exploration consisting seismic survey and exploration drilling is undertaken. In 2011, exploration drilling was done in 99 wells of 237 planned wells. The number of development wells reached 905 higher than programmed of 895 wells as shown in Figure 6. Recently, it is noted that KKKS operating in Indonesia is 256 KKKS, in which 67 KKKS are in production, while 157 KKKS are in exploration and 50 KKKS are CBM. In the last 3 years, the bidding for oil and gas working areas tends to decrease due to lack of good quality data. To encourage investors to be interested in developing oil and gas in Indonesia, the government has to try to improve such data, especially survey and seismic data quality. To address this issue, a workshop organized by the Geological Agency of Ministry of Energy and Mineral Resources was held on June 2011 to set up a “Road Map for Upstream Exploration of Oil and Gas”. CBM exploration and development has intensified in Indonesia in recent years, particularly since the first Production Sharing Contracts were awarded in 2008. At the same time gas prices have risen sharply, to $11/Mcf in Central Sumatra and $15/Mcf in East Kalimantan. (Note that gas prices are 5 to 10 times higher than in North America.) In March 2011 BP and ENI (VICO) established the country’s first commercial CBM production, exporting liquefied natural gas from the under-utilized Bontang liquefaction facility to the high-priced north Asia markets. This project established the world’s first export of CBM-to-LNG, several years ahead of the Australian plants under construction. ENI estimated CBM production could reach 420 MMcfd by 2020 from their 13-Tcf block. ExxonMobil, TOTAL, Dart Energy, and Santos also are testing CBM PSC’s, some quite close to CBM Asia’s interests. To date, there are 52 active CBM Production Sharing Contracts across 11 different basins. Figure 1 depicts Indonesia’s CBM contract area map as of August 2011. Indonesia is developing unconventional gas (that is shale gas) besides CBM. Indonesian shale gas potency is predicted at around 574 TSCF. It is bigger than CBM, which is about 453 TSCF. Shale gas is gas generated from shale rock fragments or a place in which natural gas is formed. The process needed to change shale rock to becoming gas is about 5 years. The

CCOP Member Country Report: INDONESIA 5 government now is compiling rules of law for shale gas development. Shale gas development is a matter previously never considered. However, by technology advance, this can now be developed. Based on identification result held by the government, there are 7 basins in Indonesia containing shale gas. The most basins are in Sumatera, namely Baong Shale, Telisa Shale, and Gumai Shale. While in Java Island and Kalimantan, shale gas is in 2 basins each. In Papua it is in the Klasafet formation. Up to now, the government has accepted the proposal of joint studies of shale gas from many investors. The expanded use of coal for power generation will significantly increase emission of CO2. With regard to this, it is imperative for Indonesia to investigate options for Carbon Capture and Storage (CCS) in order to achieve the CO2 emissions abatement target for 2020. Deployment and development of CCS in Indonesia is also enabling development of highly contaminated gas fields as, for instance, Natuna D Alpha. To anticipate the implementation of CCS technology in Indonesia, LEMIGAS has initiated development of a short-term R&D Roadmap. Last year, LEMIGAS has been successfully mapping potential geological formations for CO2 storage across the country along with their storage capacity. LEMIGAS has also identified large stationary CO2 sources in Indonesia. Another assessment was focused on CO2 management of low-rank coal utilization in South Sumatera and East Kalimantan. Since CCS requires extensive funding, international support from worldwide organizations, such as IEA or ADB, plays an important role in funding CCS activities in Indonesia. With regard to this, the is open for any kind of mutual cooperation for the benefit of both. An international workshop on “Determining the Potential for Carbon Capture and Storage in Southeast Asia”, organized jointly by Research and Development Center for Oil and Gas Technology “LEMIGAS and Asia Development Bank (ADB), was held in , 25 April 2012. 2.1.3. Proposed Future Activities The growing fossil-fuel needs overshadowed by the decline of oil and gas production and the threat of disruptive climate change are major challenges in the energy sector. Key areas for international collaboration to address these issues are: • Sharing best practice and lessons learnt in finding oil and gas in remote areas, such as the deep sea. • Sharing best practice and lessons learnt from oil and gas brown fields development to maximaise recovery. • Sharing best practices and lessons learnt from CCS projects in conjunction with EOR or enhanced gas recovery (EGR). • Sharing best practices and lessons learnt in developing unconventional hydrocarbon resources, such as coalbed methane and shale gas. • Continuously enhance collaboration to improve better understanding of CCS technologies.

They are mainly distributed along the Indonesian Volcanic Belts, however some are also associated with non volcanic environments (plutonic, sedimentray and tectonics). By December 2011, there were 285 geothermal locations with the total energy potential of about 29,215 MWe. These include 8,231 MWe of Speculative Resources, 4,964 MWe of Hypothetical Resources, 12,909 MWe of Possible Reserves, 823 MWe Probable Reserves and 2288 MWe of Proven Reserve. As of July 2012, thirty five (35) new working areas (WKP) have been issued by the Government, 12 WKP finish tender, 12 in bidding process, and 7 ready to bid. These areas include Jaboi (NAD), Seulawah Agam (NAD), Gunung Talang (West Sumatera), Bukit Kili (West Sumatera), Liki-Pinangawan-Muaralabuh (West Sumatera), Sipaholon-Ria (North Sumatera), Sorik Marapi-Roburan-Sampuraga (North Sumatera), Rantau Dadap (South Sumatera), Rajabasa (Lampung), Suoh Sekincou (Lampung), Tampomas (), Cisolok Cisukarame (West Java), Tangkuban Parahu (West Java), Ungaran (), Ngebel Wilis (), Blawan (East Java), Kaldera Danau (), Guci (Central Java), Baturaden (Central Java), Hu’u Daha (), Sokoria (), Atadei (East Nusa Tenggara), Jailolo (North ), Songa Wayaua (), Marana (), Suwawa (), Danau Ranau (Lampung), Bonjol (Sumatera Barat), Mataloko (NTT), Gunung Ciremai (Jawa Barat), and Gunung Endut (Banten), Bora-Pulu (Central Sulawesi), Telomoyo (Central Java), Way Ratai (Lampung) and Simbolon-Samosir (North Sumatera). Indonesia has a set of long term policies for development of geothermal energy, as embodied in the Geothermal Development Road Map of 2004-2025. Indonesia envisions that by 2025, about five percent of our national energy needs will be met through the use of geothermal energy. So far, Indonesia only used 1,226 MWe at 7 locations of the available resources. This total installed capacity is less than 4 % of the total potential. These include 387 MWe in G. Salak, 200 MWe in Kamojang, 260 MWe in Darajat, 227 MWe in Wayang Windu, 60 MWe in Dieng, 80 MWe in Lahendong, and 12 MWe in Sibayak. 2.2.2. Annual Review of Individual Technical Activities The geothermal locations are still mainlyl in the stage of inventory survey (157 locations or 53,09%). To increase the status of survey and to accelerate geothermal development, in 2012 Geological Agency is conducting preliminary surveys, detailed surveys, heat flow surveys, and core hole temperature surveys. Preliminary Survey is conducted at 3 locations: Boalemo and Pohuwatu (Gorontalo), Mamuju (), Bangka (Bangka Belitung). Detailed Survey is conducted at 6 locations: Simisioh (West Sumatera), Talu- Tombang (West Sumatera), Wai Umpu (Lampung and South Sumatera), Kawende (Central Sulawesi), Kadidia (Central Sulawesi) and G. Batur-Kintamani (). Magnetotelluric survey is conducted at 6 locations: Bittuang (), Suwawa (Gorontalo), Talu Tombang- Cubadak (West Sumatera), Kawende-Maranda (Central Sulawesi), Kadidia (Central Sulawesi) and Wapsalit (Maluku). Heat Flow Survey is conducted at 3 locations: Bittuang-Tana Toraja (South Sulawesi), Suwawa (Gorontalo), Lompi-Tambu (Central Sulawesi). Core hole temperature survey is conducted at 2 locations: Lainea () and Bukit Kili- Gunung Talang (west Sumatera). Kepahiang () and Bora (Central Sulawesi). Beside the survey activities, we evaluate 5 geothermal prospect areas (Bora Pulu-Central Sulawesi, Arjuno Welirang-East Java, Telomoyo-West Java, Kepahiang-Bengkulu, Gunung Lawu- Central Java) and examine the characteristic of non volcanic geothermal resources in South Sulawesi and Classification and Calculation of Potential of geothermal energy in Indonesia.

CCOP Member Country Report: INDONESIA 7 Also we conduct monitoring of exploration wells in Mataloko geothermal field in East Nusa Tenggara. The Geological Agency also had joint cooperation during fiscal year 2012 with the Japanese goverment (JICA) in Capacity Building for Enhancement of the Geothermal Exploration Technologies, with Indonesia University in geophysical study of geothermal resources, and Gadjah Mada University in evaluation of geothermal prospect areas. The Record of Discussions between Japan International Cooperation Agency (JICA) and Government of Republic of Indonesia for the successful implementation of the Project for Capacity Building for Enhancement of the Geothermal Exploration Technologies was signed in Jakarta, Indonesia on July 7, 2010. 2.3. COAL 2.3.1. Summary During 2011, Geological Agency has proposed 30 commercial mining business areas (WUP) for coal in Sumatera, Kalimantan dan Papua and 4 working areas (WK) for CBM in , South Sumatera and . For the past few decades, coal has acted as a buffer for conventional oil and gas that contribute to Indonesian energy demand and exports. Coal bed methane (CBM) and oil shale are the two alternative energy sources that have been considered as anticipated energy sources that are able to meet Indonesian energy demands in the future and their potential in Indonesia is continuosly revealed by several preliminary surveys and by drilling exploration conducted by Geological Agency. Resources and reserves of fossil energy comodities continue to change with the exploration and production activities of existing companies. Many private enterprises as well as state-owned coal companies (PT. Bukit Asam) based in Kalimantan and South Sumatera are still the largest contributors of coal resources, reserves and production in Indonesia. Total resources and reserves of fossil energy in Indonesia until 2011 is described in table 3 (data source: Geological Agency).

2.3.2. Annual Review of Individual Technical Activities During the mid-late 2010 until mid-early 2012, Geological Agency as a government institution in charge of doing an inventory and exploration of fossil energy resources in the provision of preliminary data have been conducting an investigation in some selected areas with different types of fossil energy commodities such as coal, coal bed methane (CBM) and oil shale. Coal inventory and preliminary survey was focused in some of Indonesia’s frontier areas such as in eastern Indonesia, tiny island and national border areas. The coal inventory of Papua concluded that coal was found in young formations (Neogene). In Kaimana, Province, the coal-bearing formation is Miocene Steenkool Formation. Coal seams with thickness less than 1 m have medium calorivic value (5951 - 6017 cal/g). In Waropko, Papua

8 CCOP Member Country Report: INDONESIA Province, the coal-bearing formation is the Holo-Pleistocene Awin Formation. Coal with thickness up to 1,5 m has low calorivic value. Small occurences of coal were also found in some tiny islands in North Mollucas Province. In Taliabu Island, Jurassic coal was found forming several seams categorized as lignitic to sub bituminous coal. Meanwhile, in South Halmahera, lensoid coal seams of Middle Miocene age have low calorific value. Coal inventory in Indonesia-Malaysia border areas were conducted in Nanga Seran, Long Pupung and Sungai Apan. These activities concluded that coal in those areas, regardless of thickness, is of good quality (high-very high rank coal) and varies in age (Cretaceous to Miocene) Inferred resources were obtained by systematic coal drilling that was conducted in two areas in Tebo Regency, Jambi Province (Muara Kilis and Muara Tebo) in order to get prospecting areas and complete the national coal database in South Sumatera basin, particularly. Those activities was conducted in the Muaraenim Formation and revealed that coal formed several seams with high variety of thickness (up to 8,85 m) and belongs to low- high rank coal categories. CBM exploration drilling was conducted in 3 main coal basins in Indonesia, namely Ombilin Basin, South Sumatera Basin and Barito Basin. CBM Exploration drilling in Sawahlunto (Sawahlunto Formation) with total depth 428,65 m revealed 6 coal seams classified as low-very high rank coal. Based on gas content and composition measurement, total methane resources is 0,604 bcf from 111 ha area investigation. CBM exploration in Lahat (South Sumatera Basin) and Balangan (Barito Basin) is being conducted and some of laboratory analyses for gas content and quality determination are still in progress. The preliminary oil shale survey is conducted in several areas of interest in Indonesia, mainly in frontier basins such as Sibolga Basin, Melawi Basin and eastern Indonesia (Maluku Island and Papua Province).

Senunu Bay, south of Big Sumbawa, Nusa Tenggara Barat Province, and 5). Rote island East Nusa Tenggara Province. The aims of the study are 1. To obtain coastal geological information with emphasis on studies of the type and physical properties of lithology, relief and shoreline characteristics; 2. Undertake sea-floor sediment sampling by using a gravity corer and grab sampler for mineral resource exploration. 3. To carry out the bathymetric survey of sea floor morphology; 4. Undertake single channel seismic reflection surveys for seismic sequence stratigraphic and geological structure studies. 4.2. Annual Review of Individual Technical Activities Thematic coastal zone survey and its resources management in Indonesia are being carried out by the Marine Geological Research and Development Center. These projects e coincide with the Planning and Development of Local Government, especially along the coastline and its surroundings and also for mineral resources development within the coastal zone. The main results of the project activities were as follows: 4.2.1. Pulau Laut, Natuna, Riau Province The study area is located at Natuna Archipelago, Riau Provines. The aim of the study is to determine the potential of alternate energy and mineral resources, coastal processes and characteristic of the islands, coastal environments and geological hazards. The bathymetric data of P. Laut show that the morphology is very deep until close to (100 m) the island but in

14 CCOP Member Country Report: INDONESIA the northern part of P. Laut and in the southeastern part is shallow due to coral reef occupying the area. Coastal processes and characteristics of P. Laut can be divided into 3 parts such as: sandy beach; mangrove beach; and cliff beach. Sandy beach can be found in the eastern part and southern part of P. Laut. The color of sands is yellowish white with size from fine grained to coarse grained and poorly sorted. Sand is dominated by biogenic debris from reef limestone. Mangrove beach is located in the southeastern part of P. Laut. The cliffs consist of stones and are located in the western part of P. Laut. 4.2.2. East Coast of Bunguran Island, Natuna, Riau Province. The result of the survey in Bunguran island, Riau Province, includes bathymetric data seismic reflection profiles, sea floor sediment and oceanographic parameters such as wave measurements and tide gauge readings. Also, the coastal characteristics of the study area were mapped. Based on the sediment samples that were taken from around Bunguran Island, the sea floor sediment types can be divided into four such as: sand, sandy silt, gravelly sand and slightly gravelly sand. Generally the distribution of sea floor sediment in Bunguran Island is dominated by silty sand located near the coral reef. Sand can be found locally along the coast of Bunguran Island. The coastal characteristic of the study area is dominantly sandy beach and rocky sand, with mangroves in some places. 4.2.3. Cilacap Coast, Central Java Province Cilacap is located in the southern part of Central Java and close to Nusa Kambangan Island. The aim of the survey of this area is to conduct a coastal geological survey in relation to geological hazards for the Pertamina UP IV harbor . The results of the survey are as follows: Seismic reflection profile data show the river channel of the Donan River and thick sedimentation around Nusa Kambangan. Bathymetric data show the morphology to be very steep close to the coastline and Nusa Kambangan Strait and becoming gradually flatter seaward at 21 m water depth. Base on the data of coastal characteristics; the area is dominated by sand and gravelly sand. Rock and conglomerate is found in some places on the eastern coast of Cilacap. Based on 33 samples of sea floor sediment, the distribution of sediment in the area can be divided into 5 types such as sand, silty sand, sandy silt, gravelly sand and muddy sand. 4.2.4. Senunu Bay, south of Big Sumbawa, Nusa Tenggara Barat Province. Senunu bay is located in the southern part of Sumbawa, Nusa Tenggara Barat. Based on mapping along the coast of Senunu, the coastline of the area is dominated by sands which contain biogenic material from coral reef. The color of sand is white and light brown. Some fine sands with iron sands are also found on the Senunu coast. Based on analyses of 20 samples, the sea floor sediment is dominated by sand. The color of sand is white grey; it is fine grained and contains quartz as well as gravel from the coral reef.

CCOP Member Country Report: INDONESIA 15 The bathymetric survey of the study area shows a relatively flat topography with depth between 20 m to 100 m, becoming very steep from 100m to 500 m depth. The area of steep morphology becomes an area of tailings from PT Newmont Nusa Tenggara. Based on the side scan sonar survey, the tailing pipes from PT Newmont Nusa Tenggara can be seen to comprise 3 pipes at the depth of 60 m, 100 m and 116 m with lengths from 2650 meter to 3100 meters. 4.2.5. Rote Island, East Nusa Tenggara Province Rote Island is located of the southwestern coast of Timor Island. The aim of this survey is to understand, for local development, the coastal environment in Rote Island. Seafloor sediment consist of silty sand, sand and reef. Sand is distributed over almost the entire study area (80%). Silty sand is located in the middle of the study area. Reef is located along the coast of the study area. Based on Coastal characteristic mapping, the study area can be divided into 3 parts such as: 1. Rocky coast. 2. Sand pocket coast. 3. Gravelly coast. Based on seismic reflection profile interpretation, the coastal terraces and shale diaper in the study area result from by tectonism. Seafloor morphology shows that the study area is characterized by undulating morphology.

26 CCOP Member Country Report: INDONESIA 6. ENVIRONMENTAL GEOLOGY PROGRAMME

6.1. Summary Rapid physical development in the Indonesian region, as reflected in more widely built- up areas and the increase the amount of provincial, regency, and municipality development, has caused a number of problems related to spatial planning and environmental management, such as land-use conflict, environmental degradation, and increased needs of geological resources. One attempt, amongst others, to solve such problems is through the supply of geo- environmental information. In the period between July 2010 and July 2012 the Geological Agency has carried out inventory and investigation activities related to the geo-environment in several provinces in Indonesia. The activities include: - Geo-environment for urban and regional spatial planning - Geo-environment for monitoring of geological hazards - Geo-environment for geological conservation - Geo-environment for waste disposal site selection - Geo-environment for flood mitigation - Geo-environment for mining areas

6.2. Annual Review of Individual Technical Activities a. Geo-environment for urban and regional spatial planning Urban and regional environmental geology investigation is aimed to provide information dealing with the environmental geology characteristics in an area which can be used as a reference for urban and regional spatial planning. Environmental geology information has the benefit that it shows supporting and constraining environmental factors for urban and regional development, therefore land use planning may not exceed its bearing capacity. The geo-environment for urban and regional planning investigation activities covers the area of: - Bali Province - East Java Province - Southeast Sulawesi Province - Aceh Province - Central Sulawesi Province - West Sumatera Province - East Nusatenggara Province - North Sumatera Province - Lombok Island, West Nusatenggara Province - Tembilahan Urban City, Riau Province - Northern Part of Bandung Area, West Java Province - Western Part of Bandung Areas, West Java Province - Kendal District, East Java Province - Kutai Kertanegara, East Kalimantan Province

CCOP Member Country Report: INDONESIA 27 b. Geo-environment for monitoring of geological hazards The activity for post geological hazards monitoring lays emphasis on the spatial function changes due to environmental geological degradation. The information provided may support utilization of the geological environment, spatial planning, and environmental management. The activity is carried out in the area of Sidoarjo mud volcano, East Java Province and post Merapi volcano eruption, Jogyakarta Province. Also Monitoring of subsidence at Semarang City, Central Java Province. c. Geo-environment for geological conservation Investigation of the geo-environment for geological conservation is done through identification and analysis of environmental geological conditions that have unique, beautiful, and rare geological morphology. The information may be utilized in conserving geological phenomena that in the future may be promoted as a geological conservation area. The aims of this activity are to conserve natural resources of geological phenomena and maintain a balanced ecosystem. Such areas may be expected to support an increase in community prosperity . The activity includes inventory of geological heritage and karstic areas. The inventory covers the areas of: - Central Java Province - East Java Province - West Java Province - Jambi Province - Indentification of Karst area in The Banyuwangi District, East Java Province - Geodiversity Inventaritation of Raja Ampat Distric, West Papua Province - Identification of Karst area in the Sukabumi Distric, West Java Province

d. Geo-environment for waste disposal site selection The most important aspect of a municipal waste disposal facility is the site.
