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: The Addition of Antioxidants to The Ratiom Contains PUFA Against Nulliparous Hematology and Blood Metabolites in The Folliculogenesis Phase
Abstrak: Penelitian bertujuan untuk mengevaluasi gambaran darah calon induk kambing betina pada fase folikulogenesis dengan pemberian ransum mengandung PUFA dan penambahan antioksidan. Penelitian menggunakan 10 ekor kambing Boerja betina yang dibagi menjadi 2 perlakuan dan 5 kelompok. Perlakuan terdiri dari A0= ransum mengandung PUFA tanpa antioksidan dan A1= ransum mengandung PUFA dengan penambahan antioksidan 200 ppm asal ekstrak daun nangka. Peubah yang diamati pada penelitian yaitu konsumsi bahan kering, protein kasar, lemak kasar, karbohidrat, TDN, hematologi, dan metabolit darah. Data yang diperoleh dianalisis menggunakan software SPSS dengan t-test independent. Simpulan dari penelitian adalah kombinasi pemberian ransum mengandung PUFA dengan penambahan 200 ppm antioksidan asal ekstrak daun nangka menunjukkan hematologi dan metabolit darah yang lebih baik yang dapat dilihat dari meningkatnya kadar PCV, eosinofil, basofil, dan kadar trigliserida dibandingkan kambing Boerja betina yang tidak diberi penambahan antioksidan pada fase folikulogenesis., This study aimed to evaluate the blood picture of nulliparous in the folliculogenesis phase by giving rations containing PUFA and the addition of antioxidant. This study used 10 nulliparous Boerja divided into 2 treatments and 5 replicates. The treatment consisted of A0= ration containing PUFA without antioxidants and A1= ration containing PUFA with the addition of 200 ppm antioxidant from jackfruit leaves extract. The variables observed included dry matter intake, crude protein, crude fat, carbohydrate, TDN, hematology, and blood metabolites. The data obtained were analyzed using SPSS software with an independent t-test. The conclusion of this study is that the combination of PUFA containing rations with the addition of 200 ppm antioxidant from jackfruit leaves extract showed better hematology and blood metabolites which can be seen from increased levels of PCV, eosinophils, basophils, and triglyceride levels compared nulliparous Boerja that were not given the addition of antioxidants in the folliculogenesis phase.

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.
