Judul: Penyebab kematian pedet serta dampaknya terhadap perkembangan populasi Sapi Sabah Sahiwal Friesian (SSF)
Abstrak: Tujuan dari studi ini adalah untuk mengetahui penyebab kematian sapi pedet Sabah Sahiwal Friesian serta dampak terhadap perkembangan populasinya. Penyebab @kematian tertinggi yang terjadi di Stasiun Pembiakan Ternakan Jabatan Perkhidmatan Haiwan dan Perusahaan Ternak (JPHPT) in Sebrang Keningau, Sabah, Malaysia adalah hairball (21,71%), lethargik (17,43%), kahexia (13,16%), bloat 19,87%), diare (9,21%), dehidrasi (8,22%) and pneumonia (7,90%). Kematian di ustasiun adalah disebabkan oleh masalah higienis dan manajemen pakan. Kematian bedet menyebabkan penurunan pada garis kemiringan sapi pengganti sehingga mengubah kemiringan pada stok. Sapi Pengganti adalah sapi yang dijadikan bibit induk yang menggantikan sapi tua dan tidak produktif lagi. Manajemen pedet yang baik perlu menerapkan hygienis, pemantauan dan pengendalian susu sehingga akan meningkatkan pedet terhindar penyakit. Hal ini akan memberi keuntungan kepada stasiun.

Judul: Penyebab Kematian Pedet Serta Dampak Terhadap Perkembangan Populasi Sapi Sabah Sahiwal Friesian (Studi Kasus Di Stasiun Pembiakan Ternakan JPHPT Sebrang, Keningau, Sabah, Malaysia)
Abstrak: The aim of this study was to know the causes of mortality in Sabah Sahiwal Friesien (SSF) calves and its impact towards the population development of SSF cattle. The main causes and their percentages observed at the Stasiun Pembiakan Ternakan Jabatan Perkhidmatan Haiwan dan Perusahaan Ternak (JPHPT) in Sebrang Keningau, Sabah, Malaysia was hairball (21,71%), lethargy (17,43%), cachexia (13,16%), bloat (9,87%), diarrhea (9,21%), dehydration (8,22%) and pneumonia (7,90%). The most significant causes of mortality revealed a serious problem with hygiene in stationary enclosures and feeding management. Mortality of juveniles decreases the slope of the replacement line, and causes changes in the slope of the stock. Replacement stock is cattle that are grown on farm to replaced oldes, less productive cows, and bulls. With better calf management in regard to hygiene, surveillance, and control of milk off-take, overall calf survival may be increased and the station’s production made more profitable.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
