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 manajemen persediaan produk ikan segar di pasar swalayan hero, Ciledug, Tangerang
Abstrak: Manajemen pengelolaan persediaan produk ikan segar yang dilakukan oleh pasar swalayan merupakan fungsi manajerial yang sangat penting dalam kegiatan pemasaran mengingat sifat ikan segar yang sangat mudah rusak dan keberadaannya dipengaruhi oleh musim khususnya ikan segar air laut. Penentuan kuantitas pemesanan persediaan produk ikan segar yang optimal merupakan bagian dari manajemen pengelolaan persediaan agar dapat menjaga kontinuitas persediaan produk dan mengefisiensikan biaya pengadaan persediaan dan hal ini dapat dianalisis dengan menggunakan metode EOQ (Economic Order Quantity). Penelitian ini bertujuan untuk mencari kuantitas pemesanan persediaan produk ikan segar yang optimal, tingkat persediaan pengaman produk ikan segar yang optimal dan titik pemesanan kembali produk ikan segar yang optimal. Hasil penelitian menunjukkan bahwa kuantitas pemesanan produk ikan segar yang diperoleh dengan menggunakan metode EOQ menghasilkan jumlah yang lebih besar dan frekuensi yang lebih sedikit daripada kuantitas dan frekuensi pemesanan yang dilakukan oleh pasar swalayan, sehingga mampu menekan biaya pengadaan persediaan menjadi lebih rendah sedangkan tingkat persediaan pengaman yang dihasilkan berdasarkan metode EOQ lebih kecil daripada tingkat persediaan pengaman yang diadakan pasar swalayan, sehingga biaya tambahan yang harus dikeluarkan menjadi lebih rendah.

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.
