Judul: Analisis Pengendalian Persediaan Ikan Segar dengan Pertimbangan Laju Kerusakan pada Bulan Januari hingga Februari 2015 (Studi Kasus Hipermarket Z).
Abstrak: Stock is one of crusial problem in supermarket. Hipermarket Z as supermarket that supply various kinds of fish has not known the optimal of inventory control management for fish. Aims of the research are to know the condition of the fish supply management in Hipermarket Z, to determine inventory model that can minimize costs, to determine the frequency of ordering and the optimal of order quantity for fish. This research uses planning approach that started from observation. The objects of the research are vanamae shrimp and gurame. Based on the calculation of the inventory model with , the optimum order from January until February for vanamae shrimp and gurame are 10.01 kg/cycle and 11.72 kg/cycle. The optimum cycle time for vanamae shrimp is 1 day. The loss of risk can reduce Rp 629 021 for shrimp and Rp 1 316 442 for gurame.

Judul: Analisis pengendalian persediaan bahan baku udang dalam bisnis udang roti PT Khom Foods, Muara Baru, Jakarta
Abstrak: Suatu badan usaha memerlukan manajemen yang meliputi pengelolaan dan pengendalian. Kegiatan perigendalian merupakan tindak lanjut dari pengawasan. Adanya keterbatasan sumber daya mendasari diadakannya manajemen produksi, yang mana pengendalian persediaan bahan baku merupakan bagian dari manajemen produksi. Karateristik dari udang membedakan manajemen pengendalian persediaan bahan baku udang dengan manajemen pengendalian persediaan manufaktur. Bahan baku utama dari produk udang roti adalah udang beku, dengan pemasaran produk ke Jepang. PT Khom Foods belum memanfaatkan model pengendalian persediaan bahan baku, selama ini perusahaan hanya melakukan manajemen persediaan dengan perhitungan sederhana. Tujuan dari penelitian ini adalah mengetahui sistem pengendalian persediaan bahan baku yang diterapkan PT Khom Foods dan menganalisis tingkat persedian bahan baku optimum bagi PT Khom Foods. Hasil dari penelitian menyimpulkan bahwa manajemen pengendalian persediaan bahan baku PT Khom Foods belum optimal. Perusahaan hanya mengandalkan pengalaman dalam melakukan perhitungan manajemen pengendalian persediaan bahan baku udang. Bagian produksi terlalu sering melakukan pemesanan bahan baku udang dalam skala kecil, dengan tujuan memenuhi kekosongan bahan baku. Pemborosan tersebut dapat dihindari dengan menggunakan manajemen pengendalian persediaan bahan baku model EOQ (Economic Order Quantity). Hasil perhitungan pengendalian persediaan bahan baku udang berdasarkan model EOQ (Economic Order Quantity) adalah perusahaan meminimalkan frekuensi pemesanan bahan baku udang dengan memaksimalkan jumlah pembelian bahan baku udang. Penerapan metode EOQ (Economic Order Quantity) akan efektif jika disesuaikan dengan fasilitas produksi yang tersedia di perusahaan. Faktor yang berpengaruh dalam penerapan model EOQ (Economic Order Quantity) adalah kapasitas cold storage dan jumlah supplier yang dimiliki oleh PT Khom Foods.

Judul: Photovoltaic Effect In A CdS/P3HT-Chitosan Junction
Abstrak: A CdS/Polymer junction has been fabricated and it’s photovoltaic effect has been studied. The polymer is a blend of poly-3hexyltiophene (P3HT), chitosan and polyethileneglicol (PEG). Boron in situ doping of CdS using Chemical Bath Deposition (CBD) was investigated. The effect of B-doping and annealing on optical properties as well as on electrical and morphology of CdS film were studied. The structure and morphology of the film were detected by XRay Diffraction (XRD) and Scanning Electron Microscopy (SEM). The polymer film was sandwiched between the CdS semiconductor and an ITO glass to form an ITO/CdS/Polymer/ITO photovoltaic cell. Time constant (τ) and open circuit voltage (Voc) were investigated by using voltage censor. The bandgap of films were determined using absorbance edge method. The results of annealing optical bandgap of undoped CdS shifted from 2,49 eV down to 2,39 eV. Phase transition of CdS due to annealing temperature and induced lattice damage due to doping. The room temperature conductivity of polymer is 3,8 – 6,6 x 10-7 S/cm as function of frequency between 100 – 5000 Hz. The Voc of the fabricated cells ranges between 107 – 286 mV and time constant ranges between 2,5 to 43,75 s.
