The authors' focus was to determine the usefulness of the fuzzy set approach in evaluating the urban residential environment, compared with the crisp (or Boolean) approach. Particular emphasis was placed upon the comparison of evaluation results produced by the two methods within a geographic information system (GIS). This comparison highlighted the advantages of the GIS-fuzzy set approach as follows. First, it was revealed that the fuzzy set approach could reduce excessive abstraction or exaggeration in environmental phenomena. Hence, without the loss of valuable information, more accurate decisionmaking can be rendered. Second, by integrating membership functions into GIS, greater efficiency of the entire evaluation process was achieved.

This case is designed to illustrate how to utilize a business intelligence framework and a geographic information system to make better decisions on franchise opening requests. The case started when Jong, the senior certified analytics professional, and his team were drafting a proposal presentation on a new franchise approval process to present to Tony, the director of Coffee Refresh. Currently, Coffee Refresh was experiencing a significant delay in approving franchise opening requests. In addition, the current approval process was relied on the appraisal teams’ evaluations, which involved self-judgment as to the accessibility and visibility of the store location in each franchise opening request and a manual count of the potential targeted customers at each location, which impacted how the appraisal teams estimated the expected revenue for each location. During the first meeting with Jong and his team, Tony was frustrated by the current evaluation process, resulting in a significant backlog of requests pending approval, which was far behind the target for its franchise branch expansion strategy. It had also been reported that the branches that opened during the past few years had a relatively low success ratio (losses between 4.8% and 16.5%) and that the rate of branch closures had increased from 2% to 7.5%. Currently, eight franchise opening requests were pending, and Jong had to provide a recommendation for which requests should be approved. Coffee Refresh could approve all of them instantly, approve some of them, or even decline all of them. This was a great opportunity for Jong and his team to revisit the current franchise approval process and to demonstrate how business intelligence systems could improve the request approval process as well as address the issues of the current franchises’ underperformance and the closure rates.

Latar belakang: Budaya membangun rumah di bantaran sungai apabila tidak diiringi dengan pemeliharaan sanitasi lingkungan, berpotensi mengakibatkan pencemaran sungai. Kondisi ini juga dapat menghasilkan berbagai permasalahan sanitasi lingkungan pada permukiman di bantaran sungai oleh tingginya aktivitas di wilayah bantaran sungai serta buangan rumah tangga. Kondisi ini yang tampak di Kecamatan Sebrang Ulu I Kota Palembang Propinsi Sumatera Selatan. Sehingga tujuan penelitian ini ialah untuk mengkaji karakteristik sanitasi lingkungan pemukiman serta program dan kebijakan yang berlaku bagi pemukiman di bantaran Sungai Musi Kecamatan Sebrang Ulu I Kota Palembang.Metode: Penelitian ini menggunakan mix method, yaitu pengumpulan data dilakukan secara kuantitatif yaitu analisis spasial menggunakan Geographic Information System (GIS), serta kualitatif melalui observasi dan wawancara. Penelitian dilakukan di 6 Kelurahan di Kecamatan Sebrang Ulu I Kota Palembang, dengan sampel sebanyak 150 orang warga dan 13 orang informan yang berasal dari masing-masing kelurahan serta petugas dinas kesehatan.  Hasil:Kondisi sanitasi sumber air dan SPAL seluruh responden tidak memenuhi syarat kesehatan. Mayoritas jamban keluarga (96,7%) dan tempat penampungan sampah (92,7%) yang dimiliki responden dalam kondisi tidak memenuhi syarat kesehatan. Program penyehatan lingkungan pemukiman khususnya rumah sehat yang diterima oleh masyarakat yang tinggal di bantaran Sungai Musi ialah berupa kunjungan oleh petugas kesehatan setempat. Serta tidak adanya kebijakan terkait pemukiman di bantaran Sungai Musi Kecamatan Sebrang Ulu I Kota PalembangSimpulan: Masih buruknya kondisi sanitasi dasar di Pemukiman bantaran Sungai Musi di Kecamatan Sebrang Ulu I Kota Palembang, serta belum optimalnya program penyehatan lingkungan pemukiman yang telah dilakukan oleh petugas kesehatan setempat. ABSTRACTTitle: Study of Settlement Environmental Sanitation in The Bank Of Musi River, Palembang CityBackground: The culture of building houses on river banks if not accompanied by the maintenance of environmental sanitation could potentially cause pollution in the river, as well as generate various environmental sanitation problems in settlements along the riverbanks. This was due to the high level of activity in the river banks as well as household discharges, which disrupts the aesthetics and function of the river. This condition was also evident in the Sebrang Ulu I Subdistrict, Palembang City, South Sumatra Province.So the purpose of this study is to examine the sanitation characteristics of the residential environment and the programs and policies that apply to settlements on the banks of the Musi River, Sebrang Ulu I District, Palembang City.Methods: This study uses the mixed method. Data collection is carried out quantitatively, namely spatial analysis using Geographic Information System (GIS), a qualitative manner through observation and interviews. The study was conducted in 6 Outlands in Sebrang Ulu I Sub-District, Palembang City, with a sample of 150 residents and 13 informants from each of the outpatients and health service officers.Results: The sanitation conditions of water sources and SPAL all respondents did not meet health requirements. The majority of family latrines (96.7%) and garbage shelters (92.7%) owned by respondents in conditions do not meet health requirements. The program to restructure the residential environment, especially the healthy houses received by the people living on the banks of the Musi River, is in the form of visits by local health workers. The absence of policies related to settlements on the banks of the Musi River in the Sebrang Ulu I Sub-District, Palembang CityConclusions: The poor condition of basic sanitation in the settlements of the Musi River banks in the Sebrang Ulu I Sub-district, Palembang City, as well as the lack of optimal environmental sanitation programs that have been carried out by local health workers.

<p>Erupsi Gunungapi Merapi tahun 2010 mengakibatkan banyak korban jiwa, kerusakan aset dan kerugian di berbagai bidang. Untuk meminimalkan korban jiwa, kerusakan dan kerugian, diperlukan upaya pengurangan risiko bencana (PRB). Salah satu upaya yang dilakukan adalah program desa bersaudara (<em>sister village</em>) yang digagas oleh Pemerintah Kabupaten Magelang melalui Badan Penanggulangan Bencana Daerah (BPBD). Program desa bersaudara ini bertujuan agar ada kepastian tempat pengungsian, mengurangi kesemrawutan proses pengungsian serta memudahkan pelayanan pengungsi. Program ini dapat memanfaatan Sistem Informasi Geografis/<em>Geographic Information System</em> (GIS) yang berbasis web (<em>WebGIS</em>). <em>WebGIS</em> mampu mendiseminasikan peta yang dihasilkan dalam program desa bersaudara, misalnya peta jalur evakuasi. Makalah ini bertujuan untuk mendiskripsikan pemanfataan <em>WebGIS</em> dalam mendukung program desa bersaudara, dengan mengambil kasus di Desa Ngargomulyo (desa rawan bencana) dan Desa Tamanagung (desa penyangga/ penerima pengungsi). Metodenya adalah memaparkan proses pemetaan jalur evakuasi. Proses penyusunan peta tersebut terbagi empat tahap:   survei lapangan, penyiapan data spasial, coding dan publikasi. Hasilnya adalah tampilan peta jalur evakuasi yang bisa diakses oleh siapapun tanpa menggunakan aplikasi GIS yang memudahkan masyarakat pengungsi, penerima pengungsi, pemerintah maupun parapihak, mengetahui asal pengungsi, jalur evakuasi dan titik pengungsian. Penelitian ini menyimpulkan bahwa pemetaan <em>WebGIS</em> dapat mendukung upaya PRB dengan keunggulan bisa dijangkau pengguna secara sangat luas.<strong></strong></p><p><strong>Kata kunci</strong>: desa bersaudara, <em>sister village</em>, pemetaan jalur evakuasi, <em>gis</em>, <em>webgis</em></p>

District of West Padang which is the area closest to the coast and has a high population. Therefore a geographic information system was created using the A-Star Algorithm method. The A-Star algorithm uses the closest distance estimation to reach a goal and has a heuristic value that is used as a basis for consideration. In this system there are alternative paths and show the amount of capacity and distance from the shelter to be addressed.
