Judul: Analisis biaya produksi kertas photocopy jenis High Brightness dan Bluish White : studi kasus di PT. Pindo Deli Pulp and Paper Karawang, Jawa Barat
Abstrak: Berkembangnya industri kertas di Indonesia didorong oleh semakin meningkatnya kebutuhan dan tingkat konsumsi masyarakat akan kertas. Pada tahun 2002 konsumsi kertas di Indonesia sebesar 5,02 juta ton meningkat terus menjadi 5,6 juta ton pada tahun 2007 dengan jumlah konsumsi kertas tulis dan cetak pada tahun 2002 sebesar 1,32 juta ton dan meningkat hingga 1,47 juta ton pada tahun 2007 (Indonesian Pulp and Paper Association 2007).Direktur Industri Hasil Hutan dan Perkebunan Kementerian Perindustrian (Kemenperin) Aryan Wargadalam (Suara Pembaruan 2 Maret 2010) mengatakan konsumsi kertas nasional naik dengan rata-rata 10% per tahun. Permintaan kertas yang paling besar adalah jenis kertas HVS atau kertas tulis, dibanding kertas lainnya, yaitu sekitar 60 % dari produksi kertas. Penelitian ini bertujuan untuk mengetahui biaya produksi dua jenis kertas photocopy lokal di PT. Pindo Deli Pulp and Paper, menentukan efisiensi produksi dengan pendekatan Break Even Point (BEP) dan pendekatan profitabilitas dengan perusahaan yang dinyatakan dengan nilai Return on Infestment (ROI) dan penentuan harga pokok kertas photocopy. Penelitian ini dilakukan di PT. Pindo Deli Pulp and Paper Karawang, Jawa Barat. Data yang dikumpulkan terdiri atas data primer dan data sekunder. Data primer meliputi proses produksi beserta alat yang digunakan, tenaga kerja, dan bahan baku yang digunakan untuk memproduksi kertas photocopy. Data sekunder meliputi kondisi umum perusahaan, jumlah produksi dan harga jual, serta data konsumsi kertas dan ekspor-impor. Hasil penelitian menunjukkan bahwa biaya produksi rata-rata kertas photocopy jenis High Brightness sebesar US$ 794,68/ton kertas dengan biaya tetap rata-rata sebesar US$ 90,07 (11,33%) dan biaya variabel rata-rata sebesar US$ 704,62 (88,67%), sedangkan biaya produksi rata-rata kertas photocopy jenis Bluish White adalah US$ 794,56/ton kertas dengan biaya tetap rata-rata sebesar US$ 90,20 (11,35%) dan biaya variabel rata-rata sebesar US$ 704,36 (88,65%). Tingkat produksi rata-rata kertas photocopy pada jenis High Brightness 3.441,20 Ton/bulan dan kertas photocopy jenis Bluish White 7.604,70 Ton/bulan. Dari hasil perhitungan dapat diketahui bahwa nilai Break Even Point jenis kertas High Brightness sebesar 573,86 Ton/bulan dan nilai Break Even Point jenis kertas Bluish White sebesar 1.373,00 Ton/bulan. Nilai ROI yang diperoleh dari usaha ini adalah sebesar 17,4%. Nilai ROI berada diatas tingkat suku bunga pada saat dilakukan penelitian yang berkisar antara 11% - 13% per tahunnya. Besarnya harga pokok kertas photocopy jenis Bluish White sebesar US$ 1.112,39/Ton, sedangkan harga pokok untuk jenis photocopy kertas High Brightness sebesar US$ 1.112,56/Ton.

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%.
