The visual character of colonial housing in Palembang Case study: Colonial housing settlement of Talang Semut in Palembang
Get PDFPalembang, having been one of the oldest city in Indonesia has inherited buildings that define an era. One of those remains are the traces of the colonial buildings in Palembang. The buildings that were built in those era are very predominant to it’s surrounding. The old Palembang area is divided with the 16 ilir in Palembang is an economic sector and the merdeka corridor is the government sector and also the Talang Semut area as a housing and settlement sector. This paper is about the traces of colonial building in the old colonial building in Palembang, represented with the Talang Semut area that have transformed into commercial places. The methods used in this study are using a visual research study to pinpoint the existing nature of the building and the transformation of the buildings as a result of changes in buildings function from settlements into micro commercial areas and also using space syntax analysis as a quantitative method to see how the streets have effected the transformation of the buildings. The transformation of Dutch and colonial places are found many in the colonial settlements in the city of Indonesia and have shaped the vibrant colors of cities in Indonesia. The Talang Semut area acts as one of the areas that transformed from settlements into micro economic, such as stores and culinary spots. The transformation of function have very much affected the visual expression of its original facade and therefore affected the character of the colonial housing settlements of Talang Semut in Palembang

The Modelling Tariff of Solid Waste Management Retributions for Malang City
Get PDFCost of solid waste management, in Malang City, can not be covered by retribution; therefore government has to subsidized. Solid waste management expense consist of TPS (temporary collection location/Tempat penampungan sementara) investment, operational/maintenance of TPS, wipe of general facility, transport from TPS to landfill and landfill treatment. This study suggest tariff retribution calculation model of solid waste mangement at Malang City. The proposed model integrate 2 method, they are Activity Based Costing (ABC) system and building type. Activity Based Costing (ABC) system is used to gather cost of waste management. While building type is used to put cost upon tariff retribution of waste management at Malang City. The early stages was to identify any activities that generate expenses in waste management. The next phase is determining the cost driver from each activites. The last step is devide amount retribution based on building type. The result from this study show that cost of street sweeping is Rp. 6.275,35/km; cost of transporting solid waste is Rp. 96.832,40/trip and cost of landfill treatment is Rp. 6.275,35/m3. After that, calculate based on solid waste generated each type building
