  • 1 Investigation of the Energy Potential from Tidal Stream
    INVESTIGATION OF THE ENERGY POTENTIAL FROM TIDAL STREAM CURRENTS IN INDONESIA Kadir Orhan1, Roberto Mayerle1, Rangaswami Narayanan1 and Wahyu Widodo Pandoe2 In this paper, an advanced methodology developed for the assessment of tidal stream resources is applied to several straits between Indian Ocean and inner Indonesian seas. Due to the high current velocities up to 3-4 m/s, the straits are particularly promising for the efficient generation of electric power. Tidal stream power potentials are evaluated on the basis of calibrated and validated high-resolution, three-dimensional numerical models. It was found that the straits under investigation have tremendous potential for the development of renewable energy production. Suitable locations for the installation of the turbines are identified in all the straits, and sites have been ranked based on the level of power density. Maximum power densities are observed in the Bali Strait, exceeding around 10kw/m2. Horizontal axis tidal turbines with a cut-in velocity of 1m/s are considered in the estimations. The highest total extractable power resulted equal to about 1,260MW in the Strait of Alas. Preliminary assessments showed that the power production at the straits under investigation is likely to exceed previous predictions reaching around 5,000MW. Keywords: renewable energy; tidal stream currents; numerical model; Indonesia INTRODUCTION The global energy supply is facing severe challenges in terms of long-term sustainability, fossil fuel reserve exhaustion, global warming and other energy related environmental concerns, geopolitical and military conflicts surrounding oil rich countries, and secure supply of energy. Renewable energy sources such as solar, wind, wave and tidal energy are capable of meeting the present and future energy demands with ease without inflicting any considerable damage to global ecosystem (Asif et al.

  • Tropical Cyclone Cempaka 'Visiting' Indonesia Right After Facing Bali's
    Tropical Cyclone Cempaka ‘Visiting’ Indonesia Right after facing Bali's Mount Agung eruption, Indonesia encounters another natural event when tropical cyclone ‘Cempaka’ hits Indonesia on 27th November 2017. Jakarta- Tropical Cyclone Warning Center (TCWC) Jakarta detected a tropical cyclone developing very close to the Southern Coast of Java. The tropical cyclone named ‘Cempaka’, has made BMKG to warn the public to prepare for extreme weather impacts for the next three days. BMKG inform the public that there are some extreme conditions causes by Cempaka such as heavy reainfall, strong winds and thunderstorms that will hit some areas of Indonesia. These heavy rains with strong winds up to 30 knots will hit Jakarta, West Java, Central Java Tengah, Yogyakarta, East Java, Kangean Island, Bali, Nusa Tenggara, and the Southern part of Java Sea. TCWC Jakarta predicts that Cempaka will remain for the next two to three days. TCWC also sending alert to public about high wave potential cause by this cyclone that up to 2.5 - 6 meters in, South Coast of East Java, the Eastern part of Java Sea, Bali Waters, Bali Strait, Alas Strait, Southern part of Lombok Strait, and Sumbawa Sea. BMKG issued warning to the public and advised people to remain calm but be aware about the following impacts that can be caused by the cyclone, such as floods, landslides, flash floods, puddles, strong winds, fallen trees, and slippery roads. Flight activities at several airports in Java may also be affected due to heavy rain and strong winds. Due to possible high sea waves, people and passing vessels are encouraged to remain on alert, especially traditional fishermen operating in the Southern Waters of Java.

  • East Java – Bali Power Distribution Strengthening Project
    *OFFICIAL USE ONLY PT PLN (Persero) East Java – Bali Power Distribution Strengthening Project Environmental & Social Management Planning Framework (Version for Disclosure) January 2020 *OFFICIAL USE ONLY BASIC INFORMATION 1. Country and Project Name: Indonesia – East Java & Bali Power Distribution Strengthening Project 2. Project Development Objective: The expansion of the distribution network comprises erection of new poles, cable stringing, and installation of distribution transformers. 3. Expected Project Benefits: Construction of about 17,000 km distribution lines and installation of distribution transformers in East Java and Bali 4. Identified Project Environmental and Social Risks: Social Risks. It is envisaged that this project will require (i) use of no more than 0.2 m2 of land for installation of concrete poles and approximately 4m2 for installation of transformers (either in cabinet of between two concrete poles or on one pole); limited directional drilling (approx. 200-300m) to run cables under major roads and limited trenching (usually less than 500m) in urban environments, and (iii) possible removal of non-land assets (primarily trimming or felling of trees) for stringing of conductors. While restrictions on land use within the existing right of way apply, the land requirements for the distribution network (lines and transformers) are considered manageable with normal mitigation measures. Project activities will not (i) require land acquisition, (ii) cause physical or economic displacement; and/or (ii) result in adverse impacts to Indigenous Peoples groups and/or members of ethnic minorities. Environmental risks are principally induced by the establishment of the network across natural habitats and potential impact on fauna (in particular avifauna and terrestrial fauna susceptible to access the distribution lines or transformers such as monkeys or other tree dwelling scavenging animals that frequent semi urban environments), and the management of waste (e.g.

    East-West Environment and Policy Institute Research Report No. 13 Indonesian Marine Fisheries Development and Strategy under Extended Maritime Jurisdiction by Salvatore Comitini Sutanto Hardjolukito East-West Center Honolulu, Hawaii THE EAST-WEST CENTER is an educational institution established in Hawaii in 1960 by the United States Congress. The Center's mandate is "to promote better relations and understanding among the nations of Asia, the Pacific, and the United States through cooperative study, training, and research." Each year more than 1,500 graduate students, scholars, professionals in business and government, and visiting specialists engage in research with the Center's interna• tional staff on major issues and problems facing the Asian and Pacific region. Since 1960, more than 30,000 men and women from the region have participated in the Center's cooperative programs. The Center's research and educational activities are conducted in five institutes- Communication, Culture Learning, Environment and Policy, Population, and Re• source Systems—and in its Pacific Islands Development Program, Open Grants, and Center-wide programs. Although principal funding continues to come from the U.S. Congress, more than 20 Asian and Pacific governments, as well as private agencies and corporations, have provided contributions for program support. The East-West Center is a public, nonprofit corporation with an international board of governors. THE EAST-WEST ENVIRONMENT AND POLICY INSTITUTE was established in October 1977 to increase understanding of the interrelationships among policies designed to meet a broad range of human and societal needs over time and the nat• ural systems and resources on which these policies depend or impact.

  • Ijen, Indonesia Geographical and Geological Summary
    Applicant UNESCO Global Geopark Ijen, Indonesia Geographical and geological summary 1. Physical and human geography summary The aUGGp Ijen area is located at the easternmost tip of Java Island in East Java Province included in the territory of the unitary Republic of Indonesia which includes 2 districts, Banyuwangi and Bondowoso Regency. The location is bordered in the north by Situbondo Regency, in the east with the Bali Strait, in the south with the Indian Ocean, and in the west with Jember Regency. The Ijen area is formed by three different layers of mountains, Giant Volcanic Complex in the north, Ancient Volcanic Hills in the southwest, and Karst Hills in the southeast. However, the main attraction in that area is the Ijen Crater. The volcano, which is 2369 m above sea level, has phenomenal blue flames and also a crater lake. Topographic altitude at the geopark area are between 0 m asl (coastal area) until 3212.5 m asl (the top of topography at the eastern rim of Raung volcano), As an area that borders the sea and the strait, the eastern tip of Java is an area of human crossing and trade intersection, making it a place of cross-cultural intersections and multicultural identities that are represented in a variety of cultures, arts, and traditions. The landscape also creates an agrarian and coastal culture which is still well preserved today. The total population in this area is 1,842,363 people with the composition of the Using, Javanese, Madurese, Balinese, Arabic, Chinese, and Bugis ethnic groups. 2. Geological Summary The early history of Ijen was centered on a single giant volcano which is estimated to have reached an altitude of 3500 m.

During the NE monsoon the winds are directed from the north and northeast to the south-west, and during the SW monsoon from the south-west to the north-east. Strong winds between June and September lead to maximum rainfall over most parts of the Indian subcontinent. These areas are also greatly influenced by the tides. The circulation in the Andaman Sea and the Malacca Strait is simulated with a three-dimensional baroclinic primitive equation model. In order to run the model, the HAMSOM model is used. The model is forced by tides at the open boundaries as well as by wind and heat flux.

The 20 M. line in the Java Sea E. of Sumatra and that for 50 M. and upwards in the eastern• most part of that sea are less accurate owing to the inequality of the sea-bot• tom there.
