Because of limited space, the siting and construction of a new SWM facility is a big challenge in Japan. An SWM facility should be socially accepted as well as environmentally and economically sound. This study aimed to investigate people's concerns about SWM facilities and their attitudes towards such facilities. A questionnaire was designed based on literature reviews and was sent to residents in three municipalities with different backgrounds. The questions covered concerns on the impact of an SWM facility, management aspects, unfairness of facility siting, and attitudes to facility construction.Of the many concerns, "pollution and health effect" had the highest rating, followed by "reliability", "damage to nature" and "cost". The rating was different between municipalities, reflecting their geographic and social backgrounds. Using factor analysis, correlations among concerns were analyzed, and five principal components were extracted, namely "pollution", "nuisance", "facility management", "planning of facility", and "merit/demerit". Although obvious correlations were not found between individual items of concern and attitudes to construction of a facility, the discriminant analysis indicated dominant concerns of attitudes, but the disagreement between actual impact and citizens were found. As for attributes, the "opposed" attitude decreased for residents who had visited an SWM facility, even if they had only seen it from outside.

Penelitian ini merupakan pengukuran dan evaluasi terhadap dampak penambangan timah inkonvensional terhadap kondisi sosial dan ekonomi masyarakat, maupun terjadinya kerusakan lingkungan akibat penambangan timah di Kabupaten Bangka Barat Provinsi Bangka Belitung. Data penelitian diperoleh dari kuesioner, observasi dan penelusuran pustaka. Pada penelitian ini akan dilakukan uji validitas dan reliabilitas kuesioner, serta penilaian awareness dan persepsi masyarakat. Selain itu akan dilakukan analisis jalur untuk melihat pengaruh variabel terhadap persepsi dampak sosial, ekonomi dan lingkungan. Penelitian melibatkan 400 responden yang dipilih secara acak di 2 kecamatan di Kabupaten Bangka Barat yaitu Kecamatan Mentok dan Kecamatan Jebus. Hasil penelitian menunjukkan bahwa pertambangan timah inkonvensional memberikan dampak negatif terhadap lingkungan dan kondisi sosial masyarakat, namun memberikan dampak positif terhadap kondisi ekonomi masyarakat. Berdasarkan analisis jalur, variabel awareness, kesediaan berpartisipasi, ekspektasi dan dukungan terhadap penambangan timah inkonvensional memiliki pengaruh yang signifikan terhadap persepsi dampak sosial, ekonomi dan lingkungan. Kata kunci: pertambangan timah inkonvensional, validitas dan reliabilitas, analisis jalur Abtract: This study is a measurement and evaluation of the impact of unconventional tin mining on the social and economic conditions, as well as the environmental damage caused by tin mining in the district of West Bangka of Bangka Belitung province. Data were obtained from questionnaires, observation, and literature review. Firstly, questionnaire need to be tested its validity and reliability before continued to assess awareness and perception. In addition there will be path analysis to observe the influene of variables to perception of social, economic and environment impacts. The study involved 400 randomly selectced respondents in the tw osub districts in the District of West Bangka, they are Mentok and Jebus. Observation result showed that the unconventional tin mining gives negative impact on the environment and social conditions, but it gives a positive impact on the economic conditions. Based on path analysis, variables of awareness, participation, expectation and support unconventional tin mining have significant effect to perception of social, economic and environment impacts.

Abstrak : Komposisi sampah di Indonesia didominasi oleh sampah organik yang berasal dari sampah sisa makanan, sementara pengelolaan sampah jenis ini telah mendapatkan perhatian khusus di beberapa negara lain seperti Amerika Serikat, Singapura, dan Inggris, di Indonesia pengelolaan sampah organic masih dititikberatkan pada metode landfilling. Dengan mengambil kota Bandung sebagai lokasi penelitian, penelitian mengenai sampah makanan ini dilakukan dengan menggunakan metode pengukuran timbulan dan komposisi sampah sebagai data primer serta pengumpulan data sekunder dengan tujuan untuk melakukan kajian dan analisa pengelolaan sampah makanan di Kota Bandung. Dengan mengambil titik sampel dalam 7 kategori (food court, RM padang, RM Sunda, hotel, PKL, RM siap saji, kafe), penelitian dilakukan sejak bulan apriljuni 2013. Kesimpulan yang didapatkan dari penelitian ini adalah timbulan sampah sisa makanan sebesar 0,23 -2 liter/orang/hari dengan komposisi sebanyak 73% merupakan sampah organik. Permasalahan teknis yang dihadapi dalam pengelolaan sampah sisa makanan adalah kurangnya kesadaran pemerintah dalam menyediakan fasilitas pengolahan sampah makanan secara khusus dan kurangnya kesadaran masyarakat untuk melakukan pemilahan.Kata Kunci : Kota Bandung, pengelolaan sampah, sampah makanan, sampah perkotaan Abstract : Waste composition in Indonesia is dominated by organic waste come from food based activity, then it is still treated together with other municipal solid waste which correlates to landfill. Meanwhile in some na tions such as United States, Singapore, and United Kingdom, this type of waste has already been given a special treatment. Using Bandung as a place for survey, this research is regarding to food waste management uses a waste generation and composition methodthat aims to analize and study the possibility of food waste management in Bandung. This research take 7 categories into samples (food court, RM padang, RM Sunda, hotel, small merchant, Fast food, café) and conducted from April -June 2013. The conclusion of this research is the waste generation is estimated to be about 0,23 -2 liter/guest/day with its biggest composition is 73% from organic waste. The technical problem that being faced is the lackness of government awareness in providing food waste composter spesifically and lack of awareness from the restaurant and hotel management in participating to sort their organic waste for composting.

This study presents the measurement of municipal solid waste (MSW) compressibility and subsequent development of a landfill settlement estimation model incorporating a correction factor accounting for initial settlement prior to the addition of pressure/municipal solid waste layers. Three layers of municipal solid waste obtained from a temporary waste station in Bandung, Indonesia, were placed in each of three different lysimeters/treatments (MSW, layer height 35 cm; MSW, layer height 70 cm; and MSW, layer height 35 cm), with a time lag of sample layer input of 2 days. Tests were then undertaken based on the ASTM D2435 test standard - Standard Test Method for One-Dimensional Consolidation Properties of Soils - revealing large immediate and secondary compression ratio values reflecting the high moisture and organic matter content of the analysed municipal solid waste. From the test results, it was also detected that the initial settlement of the analysed municipal solid waste was considerable even before the addition of pressure/further layers, ranging from 10% to 17%. Thus, a modification was made to the classical Sowers settlement estimation model in the form of a correction factor representing the initial settlement occurring prior to the addition of the municipal solid waste layers. This modification resulted in a decrease in the difference between estimated and actual settlement values, from 17% to 24% based on the Sowers equation model to below 5% using the proposed modified settlement model.
