Bulgarian Journal of Agricultural Science, 25(1), 215–221 Growing periods can be determined using water balance analysis to decrease harvest risk in certain area. Generally, there are two types of land use for crop, i.e. irrigated land and non-irrigated land. This research was aimed to determine water input, water use and water loss, consumptive use crop water balance and designing a cropping pattern on rainfed paddy fi eld at Wa- tershed Tenggarong. Determination of fi eld capacity and permanent wilting point using soil texture data was input through Bouyoucos hydrom- eter methods. The calculation of land water balance according to Thornthwaite and Mather (1957) was employed to determine the agro-climate condition, particularly the dynamics of soil moisture content to plan a general cropping patterns was used based on monthly data. The planting time period is the water holding capacity > 50% from available water. Water balance monthly indicated that this area has potential growing season about 9 months, water surplus 8 months (439.6 mm year-1) and water defi cits about 3 months (59.7 mm year-1).

Analysis of forensic engineering in building structures in Indonesia goes through se veral stages. It starts from the preparatory work, then continues with the process of identifying data needs, identifying problems, and preparing literature studies. If the data is sufficient, then it will be proceeded to the data analysis and discussion process. Based on the research findings, the main cause of the collapse of the Mahakam II Bridge in Tenggarong was the construction failure of the vertical hanging cable (clamp and saddle) connecting the main cable. However, there are a number of other possibilities that cause damage to the connecting device which includes: 1) poor maintenance, 2) fatigue in the construction material of cable hangers, 3) the quality of construction materials for the cable of connecting device, 4) procedural errors in maintenance, 5) the possibility of civil engineering rules deviations in planning, and 6) design errors in determining the type of material/ material of connecting device. Commonly, building damage is caused by several factors including: 1) low quality of materials, 2) planning errors, 3) implementation process errors, and 4) poor supervision.

  • Porosity of Sediment Mixtures with Different Grain Size Distribution
    Effect of Cohesive Material on Bank Erosion Process in Sesayap River, East Kalimantan Province, Indonesia Graduate School of Engineering, Kyoto University 〇 Puji Harsanto Disaster Prevention Research Institute, Kyoto University Masaharu Fujita Disaster Prevention Research Institute, Kyoto University Hiroshi Takebayashi 1. INTRODUCTION Riverbank erosion is a natural process that can cause the loss of useful land and endangers the safety of navigation, among others. Riverbank erosion becomes a problem or disaster, if it occurs in rivers around residential area, constructions, or others useful land. Bank erosion processes are essentially dominated by the complicated interaction between flow, sediment transport, and bank material (Duan, 2001). Horizontal shift speed of bank is changed rapidly when the bank is composed of both the non-cohesive material layers and the cohesive material layers such as the bank erosions that occurred in Sesayap River, East Kalimantan, Fig. 1. Sesayap River at Malinau Indonesia (Takebayashi, 2010). Fig. 1 shows Sesayap River that passes at Malinau city. The phenomenon of bank erosion and sedimentation around the Sesayap River especially at Malinau city are: 1. Bank erosion at Seluwing area (Fig. 2) endangers the land transportation facilities in the town of Malinau and sandbars grows in the middle of the river, 2. Bank erosion at speedboat dock area (location 2). The Sesayap River is 279 km long and the catchment has an area of about 18158 km2. Sesayap River is a navigation channel which conducts between Malinau and Tarakan. At Seluwing area (location 1) riverbank was collapsed on April and September 2008. Those collapses gave damages on the road structure.

Kalimantan Utara) Island Identification at River Estuary Based on Toponymy (Case Study: River Estuary of Bulungan, Bulungan Regency, North Kalimantan Province) Yulius, I.R. Suhelmi dan M. Ramdhan Pusat Penelitian dan Pengembangan Sumber daya Laut dan Pesisir Balitbang KP-KKP e-mail: [email protected] ABSTRACT Toponymy is the scientific study of geographical names. Island Toponym represents step of island identi- fication by identifying its name and geographic position. Island Identification in toponymy was conducted through desk study and field survey. Desk study was implemented to obtain earlier description of islands physical condition, social and culture of local people. Field survey to obtain names of the islands was carried out by interviewing local people and positions were measured by using a simple GPS system then validated using nautical chart Dishidros publications 1997 and Image from Google Earth in 2013. The Survey at Bulungan Regency of North Kalimantan Province, 19 islands had been identified 7 islands which have not been listed at DEPDAGRI (Ministry of Internal Affairs) in 2004 but the other 10 islands have been named, and 9 island which is not drawn yet in sea chart published by DISHIDROS TNI-AL. Keywords: Toponymy, Island, River Estuary, Bulungan Regency ABSTRAK Toponimi adalah ilmu atau studi tentang nama-nama geografis. Toponim pulau merupakan langkah dalam identifikasi pulau dengan konsentrasi pada nama-nama pulau beserta posisinya. Indentifikasi pulau dalam toponimi dilakukan melalui studi pustaka dan survei lapangan.

  • A Punan Hunter-Gatherer’
    Copyright © 2007 by the author(s). Published here under license by the Resilience Alliance. Levang, P., S. Sitorus, and E. Dounias. 2007. City life in the midst of the forest: a Punan hunter-gatherer’s vision of conservation and development. Ecology and Society 12(1): 18. [online] URL: http://www.ecology andsociety.org/vol12/iss1/art18/ Research, part of a Special Feature on Navigating Trade-offs: Working for Conservation and Development Outcomes City Life in the Midst of the Forest: a Punan Hunter-Gatherer’s Vision of Conservation and Development Patrice Levang 1, Soaduon Sitorus 2, and Edmond Dounias 1 ABSTRACT. The Punan Tubu, a group of hunter-gatherers in East-Kalimantan, Indonesia, are used to illustrate the very real trade-offs that are made between conservation and development. This group has undergone various forms of resettlement in the 20th century, to the point that some are now settled close to the city of Malinau whereas others remain in remote locations in the upper Tubu catchment. This study is based on several years of ethnographic and household analysis. The Punan clearly favor both conservation and development. In the city, the Punan benefit from all positive effects of development. Child and infant mortality rates are very low, and illiteracy has been eradicated among the younger generation. However, the Punan complain that nothing in town is free. The older generation, in particular, resents the loss of Punan culture. Because of frustration and unemployment, young people often succumb to alcoholism and drug addiction. The Punan do not want to choose between conservation and development, between forest life and city life.
