Judul: Analisis Biaya Produksi Papan Partikel: Studi Kasus di PT. Paparti Pertama Kabupaten Sukabumi Jawa Barat
Abstrak: A policy in determining the main price of the particle board is strongly influenced by the cost of production. The purpose of this study was to analyze the cost of production of particle board business in PT. Paparti Pertama to determine the extent to which companies make a profit. Three things are needed in this analysis is the value of production costs include fixed costs and variable costs, the value of Break Even Point (BEP), and the value of Return on Investment (ROI). Based on analysis study, production cost for every comodity is around Rp 1.689.398 to Rp 1.721.434 per meter cubic, with fix cost (29.25%) and variable cost (70,75%). Value of Break Event Point (BEP) 93,11 m3 per month and the value of Return on Investment (ROI) 9,29%. Based on the results of this analysis indicate that the company has the ability to earn greater profits than investment in the form of deposit.

Judul: Analisis Biaya Produksi Grease Proof Board (Studi Kasus PT Indah Kiat Pulp and Paper, Serang Mill)
Abstrak: Perkembangan industri kertas di Indonesia sejalan dengan permintaan terhadap kertas. Saat ini selain untuk kebutuhan dalam negeri, industri kertas di Indonesia juga memenuhi permintaan pasar luar negeri. Namun pada kenyataannya pasokan bahan baku masih terbatas dan produksi belum dapat mengimbangi permintaan yang semakin tinggi sehingga industri pulp dan kertas di Indonesia belum memiliki daya saing yang kuat dengan industri pulp dan kertas di luar negeri. oleh karena itu peningkatan produksi dan daya saing harus dilakukan Industri pulp dan kertas di Indonesia, sehingga untuk mencapai target tersebut perlu adanya perencanaan biaya produksi yang matang untuk dapat menghasilkan profitabilitas produksi yang tinggi. Penelitian analisis biaya produksi Grease Proof Board dilakukan di PT Indah Kiat Pulp and Paper, salah satu perusahaan kertas terbesar di Indonesia.Hasil penelitian menunjukkan bahwa biaya produksi rata-rata untuk Grease Proof Board adalah US$ 694,54/ton, yang terdiri dari biaya tetap dengan rata-rata sebesar US$ 146,62/ton dan biaya variabel dengan rata-rata sebesar US$ 547,92/ton dengan produksi rata-rata sebesar 1.650 ton/bulan. Hasil perhitungan yang telah dilakukan didapat bahwa nilai Break Even Point sebesar 807,23 ton/bulan, sedangkan nilai ROI perusahaan sebesar 16,80% dan harga pokok sebesar US$ 833,44/ton.

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.
