Judul: Analisis Willingness To Pay Pengelolaan Sampah Pasar Tradisional Kota Bogor
Abstrak: In correspond with the increase population, the quantity of solid waste is also increase. At present condition, the increasing quantity of solid waste could not be followed by its proper management, so many municipalities in Indonesia have serious problem to handle all waste generated. Unmanage solid waste has creating as a source of pollution, disease (and health aspect) and aesthetic problems. This study was conducted in Bogor traditional market for learning on willingness to pay (WTP) for handling the market solid waste management. Contingent Valuation Method (CVM) was used as a method in this study. The average WTP value of large, medium and small market seller was Rp 4,255, Rp 3,603 and Rp 3,212 per day respectively. The total WTP for the whole market was Rp 22,126,391 per day. The resulted conclusion was that the raising amount fund collected could be used to increase proper waste management and auxiliary benefit the environmental pollution could be eliminated.

Judul: Karakterisasi dan Analisis Potensi Kompos Sampah Padat Pasar Tradisional di Pasar Bogor
Abstrak: Traditional market solid waste is highly potential to be composted as based on its high organic matter content. Bogor market as one of the traditional market in Bogor municipality yet have the waste characteristics data that can be used as the basis of the waste processing. The objective of this research was to characterize the solid waste, to analyze compost potention of Bogor market waste to be composted. Characterization referred to SNI 19-3964-1995 and chemical analysis was carried out in the laboratory. The result shows that the solid waste generation of Bogor market reaches 27.0 m3 or approximately 7.2 tons of solid waste per day. Bogor market waste composition includes 84.0% organic waste, 7.1% plastic, 6.7% wood and 2.1% paper. The result of laboratory analysis showed that water content, ash content, volatile content, C/N ratio and caloric value are 83.39%, 2.02%, 14.58%, 27:1 and 4589 cal/g, respectively. The available land area can accommodate total material volume 31.76 tons waste and can produce 148.8 tons compost. The value of economic feasibility shows that the value of NPV (Net Present Value) and B/C ratio less than feasible standard. This shows that the compost installation is not economically feasible to be built.

Judul: Penyusunan Overlap Graph menggunakan Suffix Tree pada DNA Sequence
Abstrak: The DNA sequence assembly is very important in genome analysis. This step aims to reconstruct contigous DNA fragment (contigs) from short fragment by concatenating fragments based on the overlap region among them. This method employs overlap graph for solving the problems. In this graph, nodes represent fragments and edges represent overlap. This research developed a software for constructing overlap graph using suffix tree. The evaluation was conducted by measuring the number of nodes, number of edges, and the execution time in many values of minimum overlap. The minimum overlap is defined as the minimum length of substring which is considered as the overlap region between two fragments. The evaluation results showed that the number of nodes, the number of edges, and the execution time were increased with the decreasing of the minimum overlap value.
