A model to contour hydrographic data was designed to determine the depth of water. Because uf sparse and random nature of the given data, we superimposed an optimally sized grid system on the region and assigned the known data at their corresponding grid points. Thon We used the principle of minimum curvature tn derive finite difference? equations that calculated the remaining grid points. We iterated these equations until a convergence criterion of 0.01 over the whole grid was reached; this gave us a grid of values to contour. To insure corvergent.e of the grid before round-off error swamped the routine, we put the grid through an initializenq routine. The Geographical Information System is used to develop a powerful set of tools for concerting and displaying hydrographic data from the real world.

The area of Bandung municipality was 16,180.65 hectares with a population of 1,806,409 persons; so that it categorized as area with high population density that was 112 persons per hectares noted in 1998. It was implied that the high density of population by land use in 1997, which was more than 70% of this area occupied for settlement and industrial regions. With such populated area, one could expect a huge amount of waste accumulated. Municipal solid waste generated approximately 8,000 m3 per day that was disposed to three disposal sites. These were located at TPA (Tempat[ Pembuangan Akhir) Sampah Leuwigajah, Jelekong and Pasir Impun. These areas operate until the year 2002. Therefore, Bandung municipality should seek a new location for disposal site. To find new disposal site based on scientific considerations, geographical information system and approach were employed. The methods used were overlaying techniques with scoring method. The scoring method consisted of physical and social parameters. To determine the most suitable location, technical measurement was also considered. Solid waste disposed to TPA will be decomposed that create odor, gas and liquid that impact on the environment. Gas, especially methane would be flammable. While, the liquid might produce leachate that will be absorbed by the soil surface. In consequence, it would contaminate the ground water. Therefore, in determining most suitable disposal site one must discern physical and social conditions. According to SK SNI T-11-1991-03 regarding TPA Sampah (Waste Disposal Site) Selection Procedures, physical condition parameters must be considered, e.g. altitude, slope, geological risk, soil type, and water table. While social condition parameters consist of population density, land use, and distance from waste source. Each parameter was scored according to the condition. Then, each thematic map was overlaid one to the other to have strata of the most suitable, suitable and not suitable areas for disposal site based on physical and social parameters. There are 37 most suitable locations that must be analyzed to obtain selected location. Then, technical consideration was applied to determine the selected location. The technical consideration parameters contained location area, water discharge and recharge system, accessibility, and distance from the river, distance from the airport, traffic condition, and windrow. The most important parameter was location area. The measurement for location area with assumption for 15 years of operation period, and eight kecamatan would dispose its waste to the selected location. The eight kecarnatan were Margahayu, Margaasih, Katapang, Dayeuhkolot, Soreang, Cimahi Selatan, Cimahi Tengah and Cimahi Utara. These were highly dense population, so that it would not have its own disposal site. The disposal site area required would be around 212.12 hectares. In conclusion, the proposed, most suitable location for Bandung Municipal Solid Waste disposal site would be the area of 357.49 hectares, which was located in the border of Kecamatan Soreang and Katapang.

Berbagai metode dan model terkait optimasi sistem pengumpulan sampah telah banyak dikembangkan, mulai dari model matematis klasik hingga aplikasi teknologi terkini yang terintegrasi dengan data aktual. Salah satu model untuk menyelesaikan permasalahan operasional pengumpulan sampah yang banyak dikaji adalah model berbasis Sistem Informasi Geografis. Penelitian ini bertujuan untuk memodelkan sistem pengumpulan sampah komunal dan mencari alternatif rute pengumpulan sampah yang optimal menggunakan konsep analisis jaringan pada model berbasis Sistem Informasi Geografis, dengan studi kasus adalah wilayah Kelurahan Pondok Pinang, Kecamatan Kebayoran Lama, Jakarta Selatan. Hasil penelitian menunjukkan bahwa model analisis spasial yang mengkombinasikan pemetaan grid jangkauan pelayanan dengan sistem jaringan jalan dapat digunakan untuk mencari jumlah dan lokasi kontainer komunal yang optimal untuk diterapkan dalam sistem pengumpulan terpisah sampah plastik dan kertas di Kelurahan Pondok Pinang. Optimasi rute kendaraan pengumpul sampah dapat dimodelkan melalui modifikasi konsep analisis jaringan dengan cara mengkombinasikan dan mengubah parameter persampahan dan transportasi ke dalam dimensi waktu untuk dijadikan atribut hambatan. Di samping itu, metode pembobotan parameter analisis juga dapat dijadikan sebagai suatu metode alternatif penentuan impedansi dalam optimasi pencarian rute menuju TPS. ......In recent years, various optimization models related to waste collection system have been proposed, ranging from the classical mathematical models up to the latest technology applications that are integrated with real time data. Geographical Information System is used in studies on waste collection optimization. This thesis proposed the use of Geographical Information Systems (GIS) modelling software to optimise the location of containers used for the paper and plastic waste and describes a method to find the best waste collection route in Pondok Pinang, Kebayoran Lama District, South Jakarta. The results of study showed that the spatial analysis model which combines the range of influence grid mapping with road network system can be used to find the optimum number and location of containers for plastic and paper collection systems in Pondok Pinang. The optimization of waste collection route can be modeled through a modified concept of network analysis by combining and converting the parameters of the waste characteristic and transportation system into the time dimension which is used as a impedance factor. In addition, the weighting parameter analysis can be used as an alternative method to determine the impedance in the routing model.

Management of Conservation Region in Bandung Basin using Bioregional Planning ApproachThe title of the research thesis is "Management of Conservation Region in Bandung Basin using Bioregional Planning Approach". The research objective is to understand the change of bio-geophysical aspects according to time and spatial dimensions. In general, regional planning is attempted by partial approach, i.e. sectors. Therefore, the benefit is not for longer term of development. Having such a limitation, one could consider more comprehensive approach. Bioregional planning concerns with bio-geophysical and social aspects in managing the region. This might be more appropriate for longer term regional development plan. In this research, the element of land use taken account was the forest region. So that, in managing conservation area in Bandung Basin, bioregional planning approach was applied. In this research, the conservation considered was the forest region. The method of research was using geographical information system application and regression analysis. Variables measured were land-uses in 1986, 1993 and 1997; and changes for the periods. Other variables were slope and altitude. Variables of social aspects used were population density and population proportion for agriculture. To measure land use change, overlaying technique was applied. The result showed that forest area in 1986 - 1993 reduced rapidly and changed for settlement, encroaching about 1 331.49 hectares covered 25 kecamatan. The largest part of this area was in Kecamatan Cimenyan. The change in period of 1993 to 1997 was 13.79 hectares; this occurred only in Kecamatan Cimenyan. Overlaying method of slope and land use, gave result in that there were settlements in region with slope of more than 50% and covering about 135.64 hectares in 1993 and 58.87 hectares in 1997. The result of regression analysis was the forest area in 1986 related closely to population density. This was concluded from R-square of more than 0.5 in the first and second segment of the selected study areas. The co-relation of forest area variables and population percentage in agricultural sector gave a good result in the third segment in 1997. This concluded that the major driving force of reduction in forest area was due mainly to the population percentage in agricultural sector, not to the population density upon forested area. In conclusion, the information can be used as an input for regional planning because it concerns with biological components caring for sustainable managing conservation in Bandung Basin. Further research might be expanded to involve some aspects, especially on the community participation for agricultural sector and vegetation analysis for biodiversity study.

Penyakit Kaki Gajah (Filariasis) adalah penyakit menular yang disebabkan oleh infeksi cacing filaria yang ditularkan oleh berbagai jenis nyamuk. Diperkirakan penyakit tersebut menginfeksi sekitar 120 juta penduduk di 80 negara. Berdasarkan hasil survei cepat (Rapid Mapping) Filariasis tahun 2000 menunjukkan jumlah kasus kronis sebesar 6.500 orang tersebar di 1.553 desa. 674 puskesmas dan 231 Kabupaten/Kota- Microfilaria Rate (Mf. Rate) : 3.1 % (Ditjen PPM-PL. 2001). angka ini jauh lebih tinggi dari standar Mf. rate < 1 %. Deegan Mf. Rate 3,1 berarti penularan masih terus berlangsung (WHO. 2000). Di Kabupaten Bekasi sampai dengan September 2003 ditemukan 61 kasus klinis dan Mf. Positif 155 orang di 13 kecamatan dari 23 kecamatan dengan Mf. Rate rata-rata 1.30 %, sehingga transmisi penyakit kaki gajah masih mengkhawatirkan. Penemuan penderita dan sebaran kasus cenderung meningkat selama 3 tahun terakhir karena meningkatnya kualitas informasi dan pengetahuan masyarakat tentang penyakit kaki gajah (Filariasis). Langkah-langkah pengembangan mengikuti tahapan metode System Development Life Cycle (SDLC) seperti planning, analysis, design. implementation, maintenance dan evaluation yang memadukan konsep Data Base Management System (DBMS) dan data spatial sehingga menjadi kekuatan dalam SIG. Hasil analisis sistem dapat mengidentifikasi permasalah pada pengelolaan informasi penyakit kaki gajah. serta alternatif pemecahannya pada setiap aspek (input, process dan output). SIG Penyakit Kaki Gajah (Filariasis) dapat menghasilkan output dalam bentuk tabel untuk pelaporan, grafik serta peta. Dengan SIG sebaran kasus(difusi) selama 3 (tiga) tahun dapat dilihat bahwa adanya difusi ekspansi kasus klinis maupun Microfilaria Positif pada desa-desa yang telah disurvei. Hasil analisis overlay antara daerah endemis dengan sebaran kasus klinis dapat dilihat adanya kasus klinis pada daerah non endemis. Bentuk-bentuk keluaran ini dapat dijadikan bahan masukan pada pengambil keputusan dalam eliminasi penyakit kaki gajah (frlariasis). SIG ini diharapkan dapat dijadikan alat/tools bagi pengelola program dan dimungkinkan dapat dikembangkan di Kabupaten lain. ......Filariasis is a contagious disease caused by infection of filarial worm spread by a variety of mosquito. It was predicted that the disease infected around 120 million people in eighty countries across the world. In Indonesia, based on rapid mapping on filariasis at 2000, 6500 chronic cases were found, spread across 1553 villages, 674 public health center, and 231 districts/cities. Microfilaria rate (Mf rate) of 3.1% (Ditjen PPM-PL, 2001), this rate was far higher than Mf rate standard of WHO and this meant that the spreading of the disease is still going on (WHO, 2000). In Bekasi District, until September 2003, 61 clinical cases were found with positive Mf of 155 people spread in 13 sub-districts (out of 23 sub-districts) with average Mf rate of 1.30%. Those figures signal worrying threat of spreading. Case finding shows increasing trends during the last three years due to improvement of information quality and public knowledge about filariasis. Steps of development followed the System Development Life Cycle (SDLC) method such as planning, analysis, design, implementation, maintenance, and evaluation that integrate Database Management System (DBMS) and spatial data concepts providing strong geographical information system. The result of system analysis is able to identify problems related to information management on filariasis and its solution in each aspect (input, process, and output). Geographical information system on filariasis could produce output in form of reporting table, graphical, and maps. GIS on diffusion in three years showed clinical case expansion diffusion and positive microfilaria in the surveyed villages. Overlay analysis between endemic areas and clinical cases spread showed the existence of clinical cases in non-endemic areas. The above outputs could be used as input for decision maker in eliminating filariasis disease. This GIS is expected to be used as tool for program managers and could be developed for other districts.

ABSTRACT
Current world energy consumption tends to increase from time to time due to the growth of industry and transportation. In Indonesia, Liquefied Petroleum Gas (LPG) consumption reaches above 7.5 million tons with 5.5 million tons imported through imports. The Indonesian government uses alternative energy namely Dimethyl Ether (DME) to reduce the amount of national LPG imports. The DME plant project is a project that requires a large funds and a long time, so we needed a strategic study that includes the price of raw materials, optimization of product transportation to delivery point, benefit cost analysis of the application of DME and planning "market awareness" program. Optimization of product transportation is one aspect that influences the reduction project costs. This study aims to develop models of several objectives in finding the most optimum transportation routes. Path selection is carried out with several aspects considered such as environmental, social, and economic aspects. Geographical Information System (GIS) is a technology used in determining transportation routes for trucks. A goal programming model was developed to illustrate these aspects. The results of this study can be an additional analysis for policymakers in the selection of existing transportation routes.
