Judul: Analisis finansial pengoperasian Unit Pengolahan Air Bersih (Water Treatment Plant) Kampus IPB Dramaga Bogor
Abstrak: Air merupakan kebutuhan pokok setiap orang, karena tanpa air kehidupan tidak akan berlangsung dengan baik. Sehingga pengembangan dan pengelolaan sumberdaya air sangatlah berperan penting dalam memenuhi kebutuhan air bersih. Penyediaan air bersih oleh Institut Pertanian Bogor saat ini menggunakan unit pengolahan air bersih atau water treatment plant (WTP). Terdapat 7 unit WTP yang mengolah air baku dari dua sumber, yaitu Sungai Cihideung dan Sungai Ciapus. Sebagai langkah untuk mengevaluasi dan pengembangan WTP yang ada di kampus IPB Dramaga, maka harus dilakukan analisis mengenai operasional maupun ekonomi.

Judul: Evaluasi Kinerja Instalasi Pengolahan Air Bersih Unit 1 Sungai Ciapus di Kampus IPB Dramaga Bogor
Abstrak: Water is an important resource for human life needed continually in its daily activity. IPB uses river Cihideung and river Ciapus as the main water resource for fulfilling the campus water need. IPB has nine Water Treatment Plant (WTP). One of the WTP which is not optimally functioned enough is Unit 1 river Ciapus WTP with the capacity for about 20 liters/second. The aims of the research are to evaluate Ciapus WTP design criteria by comparing the design criteria based on SNI 6774-2008 concerning WTP package unit plan system. This research was carried out by collecting primary data, laboratory analysis, and based design criteria result evaluation. As a whole, it can be said that WTP performance still worked well enough because it had fulfilled the applicable criteria design, that is SNI 6774-2008. However, there were some units which had not yet fulfilled the criteria design, among others is coagulation, flocculation, and sedimentation, therefore it caused the process of water treatment was not quite optimal and the parameter above the quality fixed standard was able to indicate that there was a decrease of capability in reducing concentration.

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.
