Abstract

Radar is one of remote sensing technology which utilizes active electromagnetic energy and are able to provide information about the characteristics of forest stand. This study utilized JERS-1 and ERS-1 radar images to analyze the relationship between the radar backscatter and forest stand characteristics such as Diameter Breast Height (DBH), basal area, and canopy cover. This research was conducted in Jambi Province, Bungo Tebo District, Sumatra, Indonesia. The research site covered the forest concession, Suku Anak Dalam, the area adjacent to Pelepat and Batang Tebo River, and Kuamang Kuning village. Gamma Map Filter with 7 x 7 window size was applied to reduce speckle noise of the SAR images (ERS-1 and JERS-1). This study found out the positive significant correlation between basal area and DBH with JERS-1 radar backscatter (i.e., r = 0.75 and r = 0.70), while ERS-1 radar backscatter has correlation (r = 0.64) with the canopy cover.

Abstract

Air bersih dan sanitasi merupakan kebutuhan utama penduduk, namun hal terebut masih merupakan masalab yang pelik di daerah-daerah pedesaan negara-negara Kamboja. Selain termasuk negara berkembang, saat ini negar itu masih dalam situasi pasca perang yang berkepanjangan. Penyediaan air yang teramati di daerab pedesaan sekitar Khum Vilei, Distrik Kompisei, Propinsi Kompong Speau, merupakan salah satu contoh penyediaan air bersih dan sanitasi bagi masyarakat di daerah pedesaan yang perlu mendapat perhatian. Sumber air untuk keperluan domestik diperoleh dari berbagai sumber, yaitu dari air hujan, air permukaan (sungai, rawa dan genangan atau kolam), dan air tanah. Air untuk keperluan domestik diperoleh dengan teknik sederhana, babkan kadang-kadang memperhatikan aspek kesehatan masyarakat. Air tersebut didapatkan dari air hujan, air permukaan dan air tanah. Sebelum digunakan (khususnya untuk masak dan minum) ditampung dan disimpan dahulu dengan tempayan khas daerah yang bersangkutan. Dalam penyediaan air bersih di daerah pedesaan faktor penguasaan teknologi dan dana yang dimiliki penduduk setempat sangat menentukan. Perang yang berkepanjangan mengakibatkan kondisi sosial ekonomi masyarakat pedesaan sangat memprihatinkan, sehingga tidak sempat memikirkan perbaikan sarana sanitasi dan masalah yang berkaitan dengan penyediaan air bersih. Hal ini membawa kepada situasi dimana penduduk menggunakan air apa adanya tanpa memperhatikan kualitasnya, dan sering tanpa memikirkan aspek kesehatan. Hal ini harus diperhatikan dalam melakukan perbaikan dan pengadaan sarana air bersih dan sanitasi di daerah pedesaan negara tersebut.

Abstract

The aims of this research are 1) to construct a spatial model of tidal flood hazard, 2) to do hazard analysis of tidal flood. Spatial modelling has been generated using Geographic Information System (GIS) software and ILWIS software was seleccted to do the model operation. Neighborhood function and digital elevation model (DEM) have been applied on the modelling calculation process. DEM data was correted and menipulated using map calculation on the digital form. Tidal flood hazard analysis has been done by means of map calulation on the tidal flood hazard map and detail landuse map. Histogram and tabulation from the result of the map calculation have been analyzed to identify the impact of the tidal flood hazard on the landuse. The highest impact of the tidal flood hazard occurs on the 1 meter of tidal flood level, where in the inundation occurs mainly on the fishpond and yard/ open space area.

Abstract

Case study: utilizing the groundwater, water resources, and surface of water to supply the drinking water for the inhabitants is Surakarta. Of the early target at 75%, the supply of drinking water for the inhabitants in Surakarta only achieves 44%. Because of this, the Regional Drinking Water ompany (PDAM) of Surakarta made a decision to: 1) utilize the debit of water production by making a deep well at a capacity of 30 liters a second for a short term, and on the basis of the study of water resource for Surakarta, for a long term; 2) minimize the water loss from 37% to 22%; and 3) fix and extend the network of distribution. In a comprehensive consideration, there are two alternatives to add the debit of water production water: 1) utilazing the water supply at 50 liters a second from Mount Lawu. However, this is not sufficient to supply the drinking water at a capacity of 200 liters a second; and 2) utilizing the water from Colo Dam with the IPA system. This can hopefully fulfill a lack of drinking water supply at 200 liters a second. However, utilizing the natural water from the groundwater must be continued to decrease PDAM’s supply.

Abstract

This reseach is excecuted in Sidokarto village Godean Subdistrial, Kabupaten Sleman, special province of Yogyakarta, and is derived from the question of how rural community uses formal and in-formal failities of lend institution (credits source) that are available in their villages. Are the debts affecting the income of rural community? The aim of this research is to find out the back ground of rural community life, public choice to decide creditor, and the income of family holder. Methodology applied in the research is a surveying methode. The seletion of the region was executed in purposive sampling tehnique and the respondents were randomly selected. The respondents were the heads of family as debtors who have taken the credit from either government or private. Analysis used in this research was frequency tabulation, cross tabulation and analysis of correlation is done by using product moment technique. The result proved that most of the debtors (more than 50%) are non peasant with low-rank education (passed and dropped out of elementary schools). Among the debtors, the greater part (93.55%), have used the formal merits i.e. KUD and BRI. Debtors choice of lend institution is in fluenced by aspect of location and the ease of service. It is proved that the more debtors live near to the lend institution, the quality of the debtors will increase. The reason why credit source is used is influenced by the question whether it is easy or not to get the debt, without taking notice of rent, although it is low enough. The result also proved that, for the greater part of debtors have used the debt money to increase the capital for non agricultural ativities.

Abstract

Geothermal energy activities are allegedly disturbing Kamojang Nature Reserve by clearing the forest. Actually, the national park according to the Law No. 41 of 1999, must not jeopardize the preservation of germplasm in it. Meanwhile, the utilization of geothermal power plant in the area is also required to meet the electricity demand in Indonesia. Land clearing as one of the activity of exploration and exploitation of geothermal coupled with the increasing of human’s activity inside the forest caused widespread deforestation. Since there is a geothermal energy project inside the Kamojang Nature Reserve, then the aim of this study is to analysis the land cover change at Kamojang Nature Reserve from year 2000 until 2011. The research showed that the type of land cover was dominated by forest for about 4231.3 ha with forest cover percentage around 51.17%. Aside of that, the land cover change caused by exploration and exploitation of Pertamina Geothermal Energy was 60.2 ha (8.90 %), while the changes caused by human activities was 614.46 ha (91.10 %). Based on these results, replanting had been done to overcome the worse effect from each activities. The extent of reforestation and enrichment conducted by PGE was 680.58 ha by involving the society who live in surrounding area.
