Judul: Identification of Sheep Breeds Slaughtered at  Aqiqah and Slaughterhouses (Case Study in Bogor City)
Abstrak: Domba memiliki peran penting dalam berbagai macam aspek kehidupan masyarakat seperti aspek pangan maupun ekonomi. Keragaman wilayah menyebabkan begitu banyak bangsa domba yang tersebar di seluruh dunia. Karakteristik performa fisik dapat membedakan antara satu bangsa dengan bangsa lainnya. Untuk mengidentifikasi jenis domba terdapat beberapa peubah yang diamati yaitu jenis domba, jenis kelamin, umur dan bobot sebelum dipotong. Tujuan penelitian untuk mengidentifikasi jenis domba yang dipotong di tempat akikah dan tempat pemotongan hewan khusus domba. Data penelitian ini diperoleh melalui identifikasi kualitatif dan kuantitatif menggunakan metode observasi. Data yang diperoleh dianalisis secara deskriptif. Data yang diperoleh selama penelitian dimasukkan ke dalam perangkat lunak Microsoft Excel dan diproses hingga ratarata, modus, nilai maksimum dan nilai minimum ditentukan. Hasil penelitian menunjukkan jenis domba yang sering dipotong adalah Domba Ekor Tipis (DET), sebagian besar yang dipotong berjenis kelamin betina (78%) dengan umur potong terbanyak pada 1-1,5 tahun (I1) dan rata-rata bobot potong sekitar 17,83±0,1 kg., Sheep play an important role in various aspects of society such as food and economy. The diversity of regions has resulted in many breeds of sheep spread across the world. Physical performance characteristics can distinguish one breed from another. To identify sheep breeds, several variables are observed, namely sheep breed, gender, age, and weight before slaughter. The purpose of the research is to identify the types of sheep slaughtered at places for aqiqah (Islamic ritual sacrifice) and special sheep slaughterhouses. The research data was obtained through qualitative and quantitative identification using observational methods. The data obtained was analyzed descriptively. The data collected during the research was entered into Microsoft Excel software and processed to determine averages, modes, maximum, and minimum values. The results of the research show that the most frequently slaughtered breed is the Thin-Tailed Sheep (Domba Ekor Tipis, DET), with the majority being female (78%), the most common slaughter age being 1-1.5 years (I1), and an average slaughter weight of about 17.83±0.1 kg.

Judul: Differences in Carcass Characteristics and Meat Quality  among Indonesian Sheeps
Abstrak: Keragaman rumpun domba lokal menghasilkan perbedaan karakteristik karkas dan kualitas daging. Penelitian bertujuan untuk mengetahui dan menganalisis perbedaan karakteristik karkas dan kualitas daging antar rumpun domba Indonesia. Penelitian ini menggunakan seratus dua puluh ekor domba jantan dengan pola pemeliharaan yang sama. Variabel yang diamati pada penelitian ini yaitu bobot hidup, bobot karkas, persentase karkas, panjang karkas, karkas dingin, pH, keempukan, persentase susut masak, serta daya ikat air. Hubungan antara karakteristik karkas dengan kualitas daging antar rumpun domba dilakukan dengan menggunakan metode analisis General Linear Model (GLM). Hasil penelitian menunjukan bahwa bobot hidup, bobot karkas, persentase karkas, panjang karkas, bobot karkas dingin, pH, keempukan, serta persentase susut masak berpengaruh secara signifikan (P<0,001) terhadap rumpun domba. Kesimpulan dari penelitian ini yaitu domba ekor gemuk memiliki karakteristik karkas yang paling baik dibandingkan domba lainnya, serta domba compass agrinak memiliki kualitas daging yang lebih unggul dari domba lainnya., The diversity of local sheep breeds results in differences in carcass characteristics and meat quality. The study aimed to determine and analyze differences in carcass characteristics and meat quality between Indonesian sheep breeds. This study used one hundred and twenty sheep with the same maintenance pattern. The variables observed in this study were live weight, carcass weight, carcass percentage, carcass length, cold carcass, pH, tenderness, cooking loss percentage, and water-binding-holding capacity. The relationship between carcass characteristics and meat quality among sheep breeds was conducted using the General Linear Model (GLM) analysis method. The results showed that live weight, carcass weight, carcass percentage, carcass length, cold carcass weight, pH, tenderness, and cooking loss percentage significantly affected sheep breeds (P<0.01). This study concluded that fat-tailed sheep have the most superior carcass characteristics compared to other sheep, and jonggol sheep have superior meat quality than other sheep.

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.
