Judul: Optimasi Distribusi Air Bersih di Asrama TPB IPB
Abstrak: One of the main issues of water distribution process relates to effectiveness of pumps operation. When a pump was turn on there will be a power surge that makes it requires higher power, such that initial power is much greater than normal power. In this manuscript, optimal use of pump for the water distribution at TPB IPB dormitory is discussed. That problem was modeled into an integer linear programming and solved by using LINGO 11.0 software. The model is solved to obtain the pump operation scheduling which minimize energy consumption of electricity.

Judul: Analisis Penyediaan Dan Distribusi Air Bersih Untuk Kampus Dramaga Institut Pertanian Bogor
Abstrak: The purpose of this study is to determine the amount of water required in each unit within the scope of IPB Dramaga campus, to find out the amount of water that can be produced IPB water treatment plant and to create water supply system. This research was conducted from June to October 2010. The result shows that WTP Cihideung-IPB is capable to produce treated water about 137.175 m3/hr, WTP Ciapus-IPB (old) can produce treated water around 44.1 m3/hr, while WTP Ciapus-IPB (new) serving residential lines is capable to produce treated water of 65.95 m3/hr. In this research note also that the amount of water used on average per day during holidays amounted is about 1806.2 m3 (993.4 m3 in Fahutan's tower and the Fapet's tower 812.8 m3) and the amount of water used per day in full activity day amounted is about 1959.77 m3 (1070.93 m3 in the Fahutan's tower and 888.83 m3 in the Fapet's tower). Also note that during holiday peak load amounted is about 137.2 m3 in the Fahutan's tower (09.00 - 10.00) and 98.8 m3 in Fapet's tower (at 7:00 a.m. to 8:00), while at full activities peak load is 132 m3 in the Fahutan's tower (at 8:00 a.m. to 9:00) and 121 m3 in the Fapet's tower (11.00 - 12.00). In the dormitory known path needs per day amounted is about 667.890 m3. From these values it can be concluded that the quantity of treated water production on campus IPB Dramaga is sufficient. However, the problems at the level of a water distribution to the consumer level often lack even absent. In terms of quality, treated water from the installation on campus IPB Dramaga have values that fall into water quality standards

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.
