Judul: Analisis Peningkatan Produktivitas Ribbed Smoked Sheet Melalui Pendekatan Produksi Bersih (Studi Kasus PT Condong Garut)
Abstrak: Ribbed Smoked Sheet (RSS) is one of the main products of PT Condong Garut. There are some inefficiencies and non-output products (NPO) in distribution management and processing RSS in factory site.Total inefficiency and non-product output in PT Condong Garut is 17.30% based on total latex produced. Cleaner production approach can be used to reduce inefficiencies and non-product outputs. Goal of cleaner productionis to improve productivity by creating some alternatives to overcome many problems that faced by company. This research also combines operations research approach to determine optimal placement of the storage location results in plantations as an alternative from cleaner production. Theeconomic feasibility test results indicate that cleaner production appropriate to be applied by company. Base on the analytical hierarchy process, main top priority in implementing cleaner production is to prioritizeproductivity factor (0.592). Afterwards, next priority is factor of cost (0.212), environmental impact (0.138), and quality (0.121).

Judul: Kajian Peluang Implementasi Produksi Bersih Di Industri Pengolahan Karet (Studi Kasus di PT Condong Garut)
Abstrak: Rubber processing industry uses the resources of large amounts of water. This causes the rubber industry has to deal with various types of wastes in the form of liquid and solid wastes and the generation of waste gas of pungent odor. Environmental problems, as a result of these activities can be minimized by applying cleaner production. Cleaner production aims to increase the efficient use of raw materials, minimize waste and the risk of direct contamination at the source. The cleaner production alternatives which are potential to be applied are good housekeeping, collects rubber particles in rubber trap, use of coagulant antibacteria, and giving incentive for industry that apply cleaner production. The total investment of these option is Rp 660.000,- with payback period (PBP) of 0,28 bulan. The use Liqiud Smoke may reduce the RSS processing cost around 17,6%, and avoid carbon dioxide pollution. The results of AHP suggests that the environment is the most important factor in the implementation of cleaner production and the most important actor is the industry. Strategy to implement good housekeeping is the most important strategies that are generated from the AHP. This result indicates the similarity of field data analysis and expert survey that good housekeeping is the most important proper strategy for implementing cleaner production at PT Condong Garut.

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.
