Judul: Pemodelan hidrolika sistem resirkulasi akuakultur terkendali
Abstrak: Aquacultural activities have high opportunity to develop. It can supply protein demand. One of the problems is that aquaculture need substantial amount of water. Effort to conserve water on aquaculture can be conducted by means of recirculation system. Water flew is the parameter in recirculation system that requires intensive attention.

Abstrak: The research of the sustainable management model’s design of Reservoir Fisheries floating cage (Reservoir Case Cirata, West Java) aims to calculate the carrying capacity, make its institutional model, build dynamic system model and assess the sustainability of the reservoir management of floating cage based aquaculture in Cirata Reservoir. The calculation of the pollution load and capacity of assimilation is used to calculate its carrying capacity and Interpretative Structural Modeling (ISM) is used to create institutional. Furthermore, Powersim software is used to create dynamic models and Rapfish used to assess the status of sustainability in the management of Cirata Reservoir. This study shows the status of water quality in Cirata reservoir has been low into high polluted (based on water quality classification class B PP 82-year-2001), the carrying capacity of the reservoir parameters in Cirata based on TSS, BOD, COD, PO4, NO3, NO2, Fe, Cd, Zn, and Mn parameter have passed the threshold of the standard quality of water in the river. The ideal reservoir management involves the central government (Ministry of Forestry), Cirata Reservoir Management Agency, Department of Fisheries and Marine West Java Province and the Ministry of Fisheries and Marine. The population growth is the factor of problem in the utilization of Cirata Reservoir. The problem follows the basic pattern of boundary dynamic model for success, tragedy of the common and shifting of the burden, with the dominant building block is reinforcing. The increased activity of the population (KJA, industry, agriculture, livestock, forest encroachment) increased sedimentation and pollution balance the functions of ecological, economic and socio-cultural. Ecology aspect is the weakest aspect in the sustainable management of Cirata Reservoir. Socio-cultural aspect is the dominant aspect as a major capital in the intervention of four other aspects. (economic, legal-institutional, technology / infrastructure and ecology).

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.
