Judul: Hematology and Blood Metabolites of Boerja Goats in Premating Phase with Rations Containing Protected PUFA
Abstrak: Pemberian PUFA menjadi salah satu upaya untuk mengoptimalkan potensi prolifik pada kambing Boerja fase dara. PUFA yang dinilai dapat memberikan dampak positif terhadap proses reproduksi adalah omega-3 dan omega-6. Penggunaan PUFA tersebut rentan mengalami biohidrogenasi dalam rumen, sehingga diperlukan proteksi dalam bentuk sabun kalsium. Penelitian ini bertujuan mengevaluasi hematologi dan metabolit darah kambing Boerja fase dara yang diberi ransum mengandung PUFA terproteksi. Rancangan percobaan yang digunakan adalah rancangan acak kelompok dengan 2 perlakuan dan 5 kelompok. Perlakuan terdiri dari P0 yang merupakan ransum mengandung PUFA tanpa proteksi, dan P1 merupakan ransum mengandung PUFA terproteksi. Peubah yang diukur adalah konsumsi zat makanan, hematologi, dan metabolit darah. Hasil penelitian menunjukkan bahwa perlakuan PUFA terproteksi tidak menghasilkan perbedaan nyata (P>0,05) pada konsumsi zat makanan, hematokrit, hemoglobin, BDM, BDP, limfosit, neutrofil, eosinofil, monosit fase luteal, basofil fase luteal, kadar glukosa, trigliserida, dan albumin. Perlakuan PUFA terproteksi memberikan pengaruh yang berbeda nyata (P<0,05) pada persentase monosit dan basofil pada fase folikuler, serta kadar kolesterol. Kata kunci: hematologi, kambing, metabolit, PUFA terproteksi, Providing PUFA can be an effort to optimize the prolific potential of heiferstage Boerja goats. PUFAs that are considered have positive impact on reproductive system are omega-3 and omega-6. The use of PUFA is susceptible to biohydrogenation in rumen, so protection in calcium soap form is needed. This research aimed to evaluate hematology and blood metabolites of heifer-stage Boerja goat fed a rations containing protected PUFA. The experimental design used was randomized block design with 2 treatment and 5 groups. The treatment consisted of P0 (ration containing PUFA without protection), and P1 (ration containing protected PUFA). The observed variable were nutrient consumption, hematology, and blood metabolites. The result showed that treatment of protected PUFA had no different significant (P>0,05) on nutrient consumption, hematocrit, hemoglobin, erythrocyte, leukocyte, lymphocytes, neutrophils, luteal phase monocytes, luteal phase basophils, glucose levels, triglycerides, and albumin. Treatment of protected PUFA had different significant (P>0,05) on percentage of monocytes and basophils in follicular phase, as well as cholesterol levels.

Judul: Characteristics of Estrous and Folliculogenesis of  Boerja Goats with Rations Containing Protected Unsaturated Fatty Acids and  Antioxidant
Abstrak: Penelitian ini bertujuan membandingkan dan mengevaluasi pengaruh pemberian asam lemak tidak jenuh terproteksi dan antioksidan dalam ransum calon induk kambing Boerja terhadap karakteristik estrus dan jumlah folikel. Penelitian ini menggunakan 2 perlakuan yaitu R0: Ransum PUFA + antioksidan 200 ppm; R1: Ransum PUFA Terproteksi + antioksidan 200 ppm dengan 5 ulangan dan dianalisis dengan Uji T. Peubah yang diukur yaitu konsumsi zat makanan, BCS, karakteristik estrus, karakteristik vulva, dan jumlah folikel. Hasil penelitian menunjukkan penggunaan PUFA terproteksi dan antioksidan nyata (P<0,05) meningkatkan nilai BCS dan suhu saat estrus, menghasilkan jumlah folikel besar lebih banyak, jumlah folikel kecil rendah, memperpendek lama estrus, tetapi tidak berbeda nyata (P>0,05) terhadap konsumsi zat makanan, onset estrus, dan jumlah folikel sedang. Simpulan penelitian ini yaitu penggunaan asam lemak tidak jenuh terproteksi dan antioksidan pada kambing Boerja menghasilkan onset estrus yang sama, memperpendek lama estrus, respon estrus 100%, jumlah folikel kecil lebih rendah, dan jumlah folikel besar lebih banyak dibandingkan dengan penggunaan asam lemak tidak jenuh yang tidak diproteksi., The aim of this study was to compare and evaluation the provision effect of protected PUFA and antioxidant addition in the ration of replacement Boerja nulliparaous on estorus characteristic and total follicles. This research used 2 treatments, namely R0: PUFA ration + 200 ppm antioxidant; R1: protected PUFA ration +200 ppm antioxidant with 5 replicates and analyzed by T test. The variables measured were nutrient intake, BCS, estrous characteristics, vulva characteristics, and total of follicles. The results showed that use protected PUFA and antioxidant significant (P<0.05) improve BCS value and temperate during estrous, produce a greater number of large follicle, a lower number of small follicles, shortened the estrous length, while it did not significantly (P>0.05) on nutrient intake, onset of estrous, and moderate total. In conclusion, protected PUFA ration and antioxidant in boerja goats resulted on the effect same onset estrous, short estrous duration, 100% estrous respons, lower number small follicles, and number of large follicles is more to compared the use unprotected PUFA.

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.
