Judul: Aplikasi Teknik Pemrograman Sasaran Dalam Optimasi Pengendalian Mutu Kertas Medium Di PT Kertas Bekasi Teguh
Abstrak: Pengendalian mutu, selain berfungsi untuk memelihara keseragaman mutu produk, juga dimaksudkan untuk meningkatkan efisiensi agar biaya produksi dapat ditekan seminimal mungkin serta meningkatkan dan menjamin mutu produk yang baik dalam jangka panjang guna memuaskan konsumen. Penelitian ini bertujuan untuk menentukan alternatip solusi dalam manajemen pengendalian mutu, khususnya dalam pengendalian proses. Nilai-nilai spesifikasi bahan baku dan proses dioptimalkan agar spesifikasi mutu produk dan efisiensi produksi dapat dipenuhi sesuai dengan urutan prioritas sasaran. Studi kasus dilakukan di PT Kertas Bekasi Teguh terhadap kertas medium yang diproduksi pada unit mesin kertas tipe "fourdrinier". Kertas medium (corrugating medium) merupakan salah satu jenis produk yang sering mendapat klaim dari pihak konsumen. Di samping itu rata-rata sekitar 7 persen dari produksi total per bulan tidak memenuhi spesifikasi standar. Pada setiap awal proses produksi, penetapan bahan masukan dan kondisi proses dilakukan melalui percobaan-percobaan hingga akhirnya dihasilkan produk sesuai dengan spesifikasi mutu yang dikehendaki. Keadaan tersebut menyebabkan produktivitas pabrik turun sampai 20 persen.

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.
