Judul: Sistem penunjang keputusan pendirian industri kompos (studi kasus di TPA Galuga, Bogor)
Abstrak: Waste becomes important environmental issue for urban people, since the waste volume is increasing due to the population growth. Currently, traditional market waste only processed in conventional way by collecting it from local waste disposal and send it to the Final Waste Disposal (Tempat Pembuangan Akhir-TPA)

Judul: Perencanaan pendirian industri kompos berbahan baku sampah kota : Studi kasus di Kotamadya Bogor
Abstrak: Perkembangan kota Bogor mendorong pertumbuhan penduduk dan perkembangan industri serta pembangunan fasilitas pendukung kota. Dampak perkembangan tersebut adalah semakin besarnya jumlah limbah yang dihasilkan, sedangkan daya dukung lingkungan semakin berkurang akibat buangan limbah tersebut. Kota Bogor menghasilkan sampah sekitar 1.965 m² setiap hari dengan komposisi 3 sampah organik 81% dari total sampah, dan berarti terdapat sekitar 1.593 m² sampah yang potensial sebagai bahan baku kompos. Berdasarkan data Dinas Kebersihan dan Pertamanan Kotamadya Bogor 1997, jumlah yang dapat terangkut sebesar 1.310 m² atau baru dapat ditangani 82% dari total sampah organik (Dinas Kebersihan dan Pertamanan Kotamadya Bogor, 1998). Berdasarkan ketersediaan sampah organik yang cukup, maka diperlukan kajian perencanaan pendirian industri kompos berbahan baku sampah kota di Kotamadya Bogor.. Hasil kajian ini diharapkan dapat memberikan gambaran tentang kemungkinan pendirian industri kompos tersebut. Ruang lingkup kajian adalah mempelajari pra-kelayakan industri kompos melalui kajian pasar dan pemasaran, teknis teknologis, manajemen operasi proyek dan finansial sebagai alternatif pengelolaan sampah pasar di Kotamadya Bogor...

Judul: Mitochondrial DNA Gene Organization and Phylogenetic Relationship of Naja siamensis
Abstrak: Naja siamensis is one of Asiatic cobra in the Family of Elapidae, known as a cryptic snake. It has many morphological variations that lead to misidentification. Misidentification can cause the wrong concept in developing antivenom types due to high snakebite cases occur in Thailand. Thus, an accurate species identification using a molecular approach is crucially required. Mitochondrial DNA has been used widely in snake molecular studies. These studies were aimed to determine the arrangement of the N. siamensis partial mitochondrial genes using reptile-oriented primers and to reveal the phylogenetic relationship among other species of Asian cobra. DNA extraction was carried out based on the standard DNA salting-out protocol and was conducted by bioinformatics analysis using BLASTn and MEGA 6 software. Gene annotation was performed against N. kaouthia complete genome. A total of 3121 bp of N. siamensis mtDNA genes were sequenced consisting of partial of six regions: 16S rRNA, ND1, tRNA-Ile, CRII region, tRNA-Leu, tRNA-Gln, and COI genes. The mtDNA gene organization of N. siamensis was predicted to has a similar pattern with the common Elapidae mtDNA gene organization. This study showed that there is a monophyletic form in Naja genus and N. kaouthia is the closest species with N. siamensis based on partial 16S rRNA and ND1 gene.
