Judul: Analisis biaya akibat penyusutan bobot badan sapi Brahman cross dari Semarang Ke DKI Jalarta
Abstrak: Penelitian ini bertujuan (a) Untuk mengetahui struktur dan besarnya biaya transportasi dalam penyaluran sapi potong dari produsen ke konsumen, (b) Untuk mengetahui besarnya persentase biaya penyusutan bobot badan sapi potong terhadap biaya total transportasi dari Semarang ke DKI Jakarta, dan (c) Untuk mengetahui pengaruh perlakuan pada ternak sapi potong saat proses transportasi terhadap penyusutan bobot badan, bobot karkas serta persentase karkas. Data yang diperoleh dalam penelitian ini terdiri dari dua jenis data yaitu data primer dan data sekunder. Data primer diperoleh dari hasil pengamatan dan inventarisasi langsung serta wawancara. Responden yang diambil terdiri dari 1 manager kandang, 3 supir truk, 3 pembantu supir, 2 pengawal ternak, dan 1 pengurus sapi potong.

Judul: Kajian produktivitas dan sifat-kimia daging sapi brahman cross pada ransum yang berbeda
Abstrak: Tujuan penelitian adalah untuk mempelajari pengaruh tiga jenis ransum berbeda terhadap produksi potongan komersial karkas, produksi komponen non karkas, pertumbuhan allometrik potongan komersil karkas terhadap bobot total daging dan bobot karkas, pengaruh bobot hidup terhadap produksi · potongan komersial karkas dan produksi komponen non karkas, pertumbuhan allometrik komponen non karkas terhadap bobot total non karkas dan bobot hidup, sifat fisik dan kimia daging, kualitas daging serta harga jual produksi ternak. Dalam penelitian ini digunakan 149 ekor sapi Brahman Cross jantan kebiri (steer) dari PT. Great Giant Livestock Co. (GGLC) Lampung 50 ekor, PT. Kariyana Gita Utama (KGU) Cicurug Sukabumi 50 ekor dan PT. Suntoryfood Corporation Lampung 49 ekor. Penggemukan sapi di PT. GGLC memakai ransum dengan komposisi:konsentrat 11-15% dan hijauan kulit nenas 85-89%, di PT.KGU 50.8% konsentrat dan 49.2% rumput raja dan PT.Suntory konsentrat 93% dan silase daun jagung 7%. Ketiga ransum tersebut masing-masing disebut sebagai Ransum A, B dan C dengan kandungan protein dan energi yang hampir sama, yaitu protein kasar 12.30-..dst

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.
