Judul: The Influence of Meat Condition and Storage Temperature on Physical and Microbiological Characteristics of Horsemeat
Abstrak: nfonnasi tentang karakteristik fisik dan mikrobiologi daging kuda di Indonesia masih sedikit. Penelitian ini bertujuan untuk mengetahui pengaruh kondisi daging dan suhu penyimpanan terhadap karakteristik fisik dan mikrobiologi daging kuda. Sampel diperoleh dari Kecamatan Binamu, Kabupaten Jeneponto. Materi yang digunakan adalah delapan ekor ternak kuda jantan lokal, berumur 7 - 9 tahun dan dipelihara dalam kondisi peternakan rakyat. Pengujian sampel daging menggunakan otot longissimus thoracis et lwnbornm. Daging kuda dikelompokkan dalam tiga kondisi, yaitu DFD, nonnal dan PSE, dan suhu penyimpanan yaitu suhu kamar (25 - 32°C) dan suhu dingin (2 - 8°C). Penelitian ini menggunakan rancangan acak lengkap pola faktorial 3 x 2. Hasil menunjukkan bahwa tidak ada interaksi antara kondisi daging dan suhu penyimpanan terhadap karakteristik fisik dan mikrobiologi pada jam kedelapan pascamati. Daging kuda dengan kondisi DFD mempunyai pH tinggi tetapi susut masak rendah daripada daging kuda yang Normal dan PSE pada jam kedelapan pascamati. Nilai pH pada penyimpanan suhu kamar lebih rendah, sedangkan keempukan lebih baik dibanding pada penyirnpanan suhu dingin. Total bakteri lebih tinggi pada daging DFD dibanding pada daging Normal dan PSE., There is limited infonnation on physical and microbiological characteristics about horsemeat in Indonesia. The objective of this study was to examine the effect of meat condition and storage temperature on physical and microbiological characteristics of horsemeat. This study was conducted in South Sulawesi, and the sample obtained from Kecamatan Bitiamu Kabupaten Jeneponto. Eight horses, 7 - 9 years old used in this study and the meat sample obtained from Longissimus thoracis et lumbomm muscle. The sample was grouped into three condition, i.e.: DFD, Nonnal and PSE, and stored in room temperature (25 - 32°C) and chilled (2 - 8°C). The data was analyzed using completed randomized design (RAL) in factorial pattern 3 x 2. The results showed that there were not interaction between meat condition and storage temperature on physical and microbiological characteristics on eight hour postmortem. The DFD horsemeat has higher pH, but lower cooking lost than Nonna! and PSE horsemeat. The pH on room temperature was lower while, tenderness better than chilled storage. The total bacteria counts was higher in D FD horsemeat than Normal and PSE horsemeat.

Judul: Karakteristik Karkas Kuda Dengan Umur, Jenis Kelamin Dan Pemanfaatan Yang Berbeda Di Kecamatan Binamu, Kabupaten Jeneponto Sulawesi Selatan
Abstrak: The study was conducted on local horse, aiming to identify the carcass characteristics of horse of different usefull (meat and draft) at different age groups (I2, I3, and I4) and sex (yeld mare and stallion). The experiment was carried out at the Horse Slaughter Place in Binamu district of Jeneponto regency, South Sulawesi. The parameters observed included body weight, carcass weight and percentage, meat and bones percentage and non carcass percentage. The results showed that sex and horse usefull had a highly significant (P<0.01) effect on carcass percentages. The carcass percentage of the stallion (59.78±1.97%) was abviously lower than that of the yeld mare (60.74±1.63%). The carcass percentage of draft type (59.88±2.52%) was abviously lower than meat type (60.59±1.86%). The influence of age on meat and bone percentage was highly significant (P<0.01). The meat percentage of I2 animal (64.53±5.68 %) was obviously lower than that of I4 animal (70.47±5.59%). Whereas, the bone percentage of I2 animal (35.47±5.68%) was obviously higher than I4 animal (29.53±5.95%). The influence of sex on bone percentage was significant (P<0.05). The bone percentage of yeld mare (29.83±5.65%) was abviously lower than of stallion (34.92±6.06%). The influence of age, sex, and different usefull on non carcass percentage was very significant (P<0.01). Non carcass percentage of I4 animal (37.90±1.70%) was obviously lower than that I2 animal (38.81±2.69 %). Non carcass percentage of meat horse (37.01±1.53%) was abviously lower than that draft horse (39.73±2.09%). Non carcass percentage of the stallion (37.67±1.94%) was abviously lower than that the yeld mare (38.54±2.39%).

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.
