Judul: Perencanaan Distribusi Fisik produk Bir Bintang di Wilayah Pemasaran DKI Jakarta dan Jawa Barat
Abstrak: Distribusi fisi merupakan aktifitas atau prooses penyaluran produk secara keseluruhan dari pusat - pusat distribusi ke pusat - pusat konsumsi. Tujuan distribusi fisik adalah untuk memberikan pelayanan yang sebaikmungkin kepada konsumen. Suatu sistem distribusi fisik dengan mendirikan gudang lokaldi wilayah pemasarannya akan menimbulkan masalah tentang jumlah dan l o k a s i gudang, pemilihan jalur distribusi , dan tingkat persediaan di masing-masing gudang lokal . Kesalahan dalam menangani masalah ini dapat menyebabkan lemahnya daya saing produk.

Judul: Perencanaan Jaringan Distrubusi Fisik Bahan Pangan Beras : Studi Kasus Depot Logistik Propinsi Lampung
Abstrak: Beras merupakan kebutuhan pokok masyarakat yang memiliki nilai ekonomis dan strategis dalam perekonomian Indoesia. Ketersediaan pangan beras pada waktu yang tepat pada daerah-daerah di Indonesia merupakan ha1 yang perlu diperhatikan oleli Pemerintah Khususnya Badan Unisan Logistik (BULOG) dan Depot Logistik (DOLOG) sebagai badan yang menangani stok dan menstabilkan harga beras sehingga diharapkan mampu memberikan pelayanan sebaik mungkin kepada konsumen. Dalam kaitannya dengan ketepatan waktu penerimaan produk ke tangan konsumen dan tersedianya pangan beras secara kontinyu. ~nakaja ringan distribusi fisik memegang peranan yang sangat penting. Tujuan utama jaringan distribusi fisik adalah mengusahakan agar produk yang diperlukan dengan cepat sampai ke tangan konsumen, dengan biaya yang seminimal mungkin, sehingga tidak membebani harga jual produk di pasaran.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
