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: Peningkatan produktivitas pada proses produksi karet alam dengan pendekatan green productivity (studi kasus di pt. xyz)
Abstrak: The productivity issues are the integral part in the industrial world. These because the productivity is one of the industrial sustainability indicators in the future. Productivity could be Improved by reducing the waste generated. The productivity improvement of natural rubber production process in the PT. XYZ have been accomplished. The current state analysis of green productivity measurement was used by using the green productivity indexing (GPI) method. The current state GPI measurement result for the production of ribbed smoked sheet is 0.269 while the brown crepe products result is 1.089. There are four alternative strategies to improve the green productivity in the PT. XYZ based on expert opinion. By using Analytical Hierarchy Process method, He reuse of water process was obtained as the alternative strategy choosen, with 0.336 for the weight value. The implementation of the selected alternative strategy shows the reducing of the Environmental impact as 3.565 for the production of ribbed smoked sheet and 0.538 for the Production of brown crepe. The implementation of the selected alternative strategies also shows the Green productivity increasing to 0.690 for the production of ribbed smoked sheet with 2.565 GP ratio and 3.889 for brown crepe product with 3.571 GP ratio.

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.
