Judul: Analisis biaya produksi kertas jenis based paper dan preprint (studi kasus di PT. Pindo Deli Pulpl and Paper)
Abstrak: Sejak tahun 1980, industri pulp dan kertas di Indonesia mengalami tahap pertumbuhan yang fantastis, sehingga pada tahun 2009 Indonesia termasuk dalam 10 besar dunia produsen pulp dan kertas. Hanya 20 pabrik pada akhir tahun 1970, berkembang menjadi lebih dari 90 pabrik pada tahun 2010 dengan kapasitas produksi 11.5 juta ton kertas dan 6.2 juta ton pulp dengan nilai devisa mencapai USD 7.34 triliyun. Saat ini, Indonesia berada diperingkat 9 di dunia dan 3 di Asia (Kemenperin 2012). Jadi analisis biaya produksi sangat penting dalam rangka untuk memenuhi permintaan konsumen dan untuk menghadapi persaingan global. Penelitian ini dilakukan di PT.Pindo Deli Pulpand Paper II unit Paper Machine 12, Karawang, Jawa Barat. Penelitian ini dilaksanakan pada bulan April-Mei 2012. Data yang digunakan terdapat dua jenis, yaitu data primer dan data sekunder. Analisis yang dilakukan adalah analisis biaya produksi, titiki mpas, analisis profitabilitas dan analisis harga pokok. Hasil penelitian menunjukkan bahwa biaya produksi rata−rata untuk based paper adalah USD 693.38/ton, di mana jumlah tersebut terdiri dari biaya tetap rata-rata adalah US59.31(8.55 634.07 (91.45%). Sedangkan rata-rata biaya produksi untuk kertas preprint adalah USD 647.96/ton dengan biaya tetap rata−rata adalah USD 61.70 (9.52%) dan biaya variabel rata-rata adalah USD 586.26 (90.48 Dari hasil perhitungan dapat menunjukkan bahwa nilai break even point untuk based paper adalah 304.21ton/bulan dan 600.42ton/bulan untuk preprint. ROI perusahaan yang diperoleh dari usaha ini adalah sebesar 29.72 901.39/ton dan biaya preprint adalah USD 725.71/ton. Kata Kunci: Biaya Produksi, Harga pokok, Profitabilitas, Pulp dan Kertas

Judul: Analisis Biaya Produksi Carbonless Copy Paper (Studi Kasus di PT. Pindo Deli Pulp and Paper Mills II).
Abstrak: The usage of papers domestically and internationally has risen every year, along with the development of world population results in the demand of paper to continuously increasing. To increase competitiveness, there needs to be regulations and good surveillance in the production activities. Analysis of production cost is one way that can be done in order to determine the most effective and efficient production process, so that hopefully pulp will be able to be produced with minimum cost and without negativelyaffecting the quality of the product itself. This paper cost analysis research is done in the department of Non- Carbon Required PT.Pindo Deli Pulp and Paper; this particular company is one of the most renowned paper production company in Indonesia. The result of this research shows that, on average, the production cost of Carbonless Copy Paper is US$1.332,26/ton, where as this value itself consists of average fix cost which is US$ 209,74/ton and average variable cost which is US$ 1.122,5/ton. The average production is 6.646,89 ton/month. The results of the calculation shows that the value of breakeven point is 2.919,75 ton/month. The ROI acquired from this company is equal to 21.36%, furthermore the basic price is valued at US$ 1.665,32/ton

Judul: Clustering metagenome fragments using growing self organizing map
Abstrak: Metagenome is a research about analyzing microbes in the large community and allowed the culture-independent. The microorganism samples taken directly from environment is not easy to assembly because contains mixture microorganism. If sample complexity is very high and come from high diversity environment, difficulties of assembling DNA sequence are increasing because the interspecies chimeras can be happen. Clustering commonly using supervised learning, but the supervised learning depends on avaibillity of data training. Because of that, in this research we used unsupervised learning to clustering the metagenome fragments. Beside that, clustering usually using the longer fragments, which is ≥ 8 kbp and have a small community (less than 100 microorganism). The purpose of this research is to analyze the effectiveness and efficiency of Growing Self Organizing Map to the clustered large community of metagenome fragments. We used trinucleotide, tetranucleotide, and combination of oligonucleotide frequency that consider the don’t care situation called spaced k-mer frequency as a features. As a feature extraction, we using k-mer and spaced k-mer. Based on parameter combination using oligonucleotide frequency, the best combine between Learning Rate and Neighborhood Size is a spaced k-mer frequency. We tested to get a better parameter combinatoin into [10 10] map size and 10 epochs training lenght. Error to mapped metagenome fragments using spaced k-mer frequency is 0.665 for quantization error, 0.06 for topographic error and 13.07% for error percentage. Using the map size between [100 – 500], map unit 300 – 5000 unit, and training lenght 10 epochs, gives the best training in the map size [100 150] with 300 map unit. The training time is 51 minutes and percentage error is 6.43%.
