Judul: Studi pengendalian kualitas papan partikel di PT Khatulistiwa Indah wood industry Kalimantan Barat
Abstrak: Tujuan penelitian ini adalah untuk mengetahui dan mem- pelajari metode pengendalian kualitas di pabrik papan par- tikel dan mencoba melaksanakan metode pengendalian kuali- tas yang akan dikembangkan yaitu metode cuplikan keteri- maan sistem Dodge-Romig serta kemungkinannya untuk bisa diterapkan dan dilaksanakan di pabrik. Hasil penelitian ini menunjukkan bahwa nilai-nilai ka- dar air, kerapatan dan pengembangan tebal papan partikel produksi PT KIWI mempunyai kualitas yang sangat terkenda- 11. Metode pengendalian kualitas sistem Dodge-Romig yang dilaksanakan dengan jumlah sampel 13 lembar mempunyai ke- telitian yang cukup tinggi dengan simpangan baku dan se- lang kepercayaan dengan tingkat keragaman yang mempunya pendugaan kualitas yang hampir sama dengan nilai simpangan baku populasi papan partikel. Oleh karena itu metode sis- tem Dodge-Romig ini lebih baik daripa metode pengendalian kualitas yang dilaksanakan di PT KIWI, baik dalam penen- tuan jumlah sampel maupun dalam menentukan peluang keteri- maan suatu lot dengan pengujian sampling. ...

Judul: Pengendalian Kualitas Pada Proses Produksi Kertas Medium di PT Indah Kiat Pulp & Paper, Serang Mill
Abstrak: Paper with several sizes plays an important role in human life especially in modern society. Now paper becomes one of human needs and is used in various cases. With times, the paper consumption surely increases because of paper characteristics easily used, practical, light, cheap and can be recycled. Based on rising need of paper, it is a challenge for thefact01Y to increase the quality, capacity, and technology in the paper production. Qualified product is affected by production level through monitoring for each level of the production process. Quality management can be used for quality control, so that it can minimize product damage. The research was conducted at PT Indah Kiat Pulp and Pap~r, Serang mill (PT IKP P). The objective of the research is to identifY level factors of production process that influence final product quality, to analyze pelformance of production process, and main parameter of product quality by using quality management technique namely cause and effect diagram and control chart, identifYing the process instability systems and analyzing the correction process by using information ji-om observation, literature study and expert opinion in the research plant.

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.
