Judul: Analisis Bobot Komponen Penyusun Karkas dan Non Karkas pada Landak Jawa (Hystrix javanica)
Abstrak: The study was aimed to analyze the weight of carcass and non carcass components in Javan porcupine. Four samples of Javan porcupines consisted of three males and one female were used in this study. Data collected were slaughter weight, weight and percentage of carcass and non-carcass components. The acquired data were descriptively analyzed. The result show that the average of carcass and non-carcass weight were 4.627,62 gram and 2.491,22 gram while the average of carcass and non-carcass percentage were 64,98 % and 35,02 % respectively. The biggest proportion of non-carcass components were head (6,46 %), spine (5,93 %), stomach (5,72 %), and blood (2,98 %) while the smallest proportion of non-carcass components were esophagus (0,13 %), pancreas (0,13 %), and spleen (0,12 %). Based on this study, the average weight of carcass in Javan porcupine was relatively high due to the thickness of porcupine meat coupled with skin and tail.

Abstrak: Penelitian ini bertujuan untuk memperoleh dan melengkapi data-data dasar gambaran darah pada landak Jawa (Hystrix javanica). Penelitian ini menggunakan lima ekor landak Jawa dewasa, yang terdiri dari empat ekor landak jantan dan satu ekor landak betina, dengan bobot badan berkisar 7-9 kg. Sampel darah diambil secara intracardial di daerah intercostales sejajar dengan olecranon. Pemeriksaan uji hematologi, meliputi pemeriksaan jumlah eritrosit, kadar Hb, PCV, MCV, MCH, MCHC, jumlah leukosit dan morfologi sel darah. Hasil penelitian menujukkan bahwa jumlah eritrosit (4.21±0.49 x106/mm3), kadar Hb (14.33±2.43 gr/dl), dan PCV (43.08±3.82%). Dari hasil perhitungan eritrosit, Hb, dan PCV, dapat diperoleh nilai MCV (102.66±4.63 fl), MCH (34.25±4.78 pg) dan MCHC (33.25±3.69%). Jumlah leukosit yang diperoleh dari hasil penelitian adalah (10.11±2.87 x103/mm3), yang terdiri dari limfosit (70.9±7.79%), monosit (1.8±0.76%), neutrofil (22.5±9.09%), eosinofil (3.6±1.64%) dan basofil (1.2±0.84%). Rataan ukuran diameter untuk masing-masing sel darah yang diperoleh dari hasil penelitian ini adalah eritrosit (7.98±0.055 μm) dengan area bikonkaf (4.15±1.135 μm), limfosit (8.5±0.5 μm), monosit (10.5±0.5 μm), neutrofil (14±0.5 μm), eosinofil (11.5±0.5 μm), dan basofil (11±3 μm). secara umum, nilai normal dan morfologi darah landak Jawa mirip dengan mamalia khususnya dengan rodensia lain dan kelinci.

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.
