The Cost

Sanitary landfill remains the most common methodology for final treatment and disposal of municipal solid waste worldwide, the cost per tonne depends on its scale. The bigger the landfill, the cheaper the cost of treatment, so the consortium of municipalities is the solution to achieve an economic scale. However, the growth of waste production introduces pressure for adequate solutions and therefore has been increasing sanitary landfill site selection studies. This study proposes a methodology for siting sanitary landfills and optimising the transport of municipal solid waste for a locality in the state of São Paulo, Brazil. Environmental, social, and economic criteria were established. Their correlated attributes were categorised into suitability levels and weighted according to multiple decision analysis. The data were organised and mapped within a geographic information system. Considering sites where landfills are prohibited, two scenarios were generated. The Mixed-Integer Quadratic Programming mathematical model is used to minimise the costs of transporting municipal solid waste and operating sanitary landfills. In Scenario 1, the results indicated that 64% of the area was suitable as a potential sanitary landfill site, 9% of the area exhibited medium suitability, and 27% of the area was classified as restricted. In Scenario 2, the results indicated that 25% of the area was suitable as a potential sanitary landfill site, 4% of the area had medium suitability, and 71% of the area was classified as restricted. The optimal solutions for Scenario 1 and Scenario 2 enabled sites to be determined for five landfills and four landfills, respectively.

The Amount Of Household Waste Produced By The Mainly Urban Population In Morocco Continues To Increase Year After Year. Morocco Is Thus Confronted With The Problems Of Storage And Disposal Of This Waste, Which Are Composed Largely Of Organic Matter, Bio-Waste. In The Recent Past, These Wastes Have Been Buried In Wild Dumps Or In Old Quarries Located In Areas Close To Urban Centers Without Any Treatment Or Control. This Can Constitute Significant Risks Both For Public Health And The Environment And For The Future Of The Socio-Economic Activities Of The Country. Determination Of Proper Landfill Site Involves Multiple Disciplines. The Landfills Contain A Large Quantity Of Solid Waste. The Management Of Solid Waste (Msw) Necessitates The Involvement Of Different Stakeholders. In This Paper, We Aim To Determine The Appropriate Landfill Site At The Level Of The Municipality Of Ajdir In The Province Of Al Hoceima Morocco. We Take Into Consideration The Opinions Of The Stakeholders. Based On Environmental, Socio-Cultural And Economic Criteria. For This Purpose, We Used In This Paper Two Multi-Criteria Analysis Methods. The Geographic Information System (Gis) And The Analytic Hierarchy Process (Ahp). First, We Created The Database Gis Related To The Study Area. Next, This Data Was Processed To Determine The Landfill Sites That Respect The Stakeholder's Priorities And Exclusion Criteria. Then, A Multi-Criteria Analysis By Ahp Method Was Carried Out To Offer Different Visual Representations Of The Possible Solutions Of The Site’s Choice, Especially The Multi-Scale, Multi-Theme Maps And The Construction Of The Free Zones Which Can Shelter A Landfill Which Will Contribute To The Evaluation Of These Criteria While Integrating The Stakeholders Who Assisted In The Rationalization Of The Sub-Criteria’s Judgments Involved In The Study.

Initial Selection

Regional feasibility analysis of landfill locations based on the environmental geology point is the initial selection in the planning of landfill sites. This research aims to assess the regional feasibility zones for landfill site in Palangka Raya city based on the environmental aspects. Observational examination and spatial analysis using geographic information system (GIS) were applied to ascertain the determination and limitation factors. The result shows that Palangka Raya could be categorized into 3 (three) zones in terms of its feasibility for the landfill area. Unsuitable zone covering an area of 165,936.69 hectares or 58.12% of total area, followed by a moderately suitable zone of 782.25 hectares (32.85%), and least suitable zone of 25,788.88 hectares (9.03%). The infeasible ones are located in districts of Sebangau and Pahandut, and some parts of Jekan Raya.

<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>
