The present study investigated the effect of graphene oxide in cellulose acetate-based composite nanofibers on the transdermal delivery of naproxen.

Penelitian tentang “Performa dan Daya cerna Domba Garut Jantan Terhadap Penambahan Fermentasi Limbah Hijauan Sorghum Ke Dalam Ransum”, telah dilaksanakan sejak Tanggal 15 September sampai dengan 30 Oktober 2015. Penelitian ini bertujuan untuk mengimplementasikan pakan berbasis limbah hijauan sorgum fermentasi terhadap performa dan daya cerna Domba Garut Jantan. Penelitian ini menggunakan 16 ekor Domba Garut Jantan umur 6-8 bulan dengan bobot rata-rata 27 kg. Domba diberi empat perlakuan yaitu R1 = 100% rumput lapangan (sebagai ransum basal); R2 = 60% rumput lapangan + 40% konsentrat; R3 = 60% limbah hijauan sorgum fermentasi + 40% konsentrat; dan R4 = 50% rumput lapangan + 50% limbah hijauan sorgum fermentasi. Penelitian dilakukan dengan menggunakan Rancangan Acak Lengkap, dan setiap domba ditempatkan pada kandang metabolis. Data hasil penelitian diolah dengan analisis Sidik Ragam, selanjutnya untuk mengetahui perbedaan antar perlakuan dilakukan Uji Beda Nyata Duncan pada tingkat kepercayaan 95%. Hasil penelitian menunjukan bahwa fermentasi limbah hijauan sorgum dapat dijadikan pakan substitusi pada saat terjadi kelangkaan rumput lapangan. Sebagai pemecahan masalah kelangkaan rumput, 50% rumput lapangan dan 50% fermentasi limbah hijauan sorgum dapat menjadi perpaduan ideal. Hal tersebut terlihat dari performa dan kecernaan pakan pada Domba Garut Jantan yang lebih baik dari perlakuan lainnya.

Dairy cooperatives plays an important role in building people’s dairy farming business in Indonesia. It needs the right strategy to strengthen the performance of dairy cooperatives. This research applied survey method and stratified proportional random sampling to determine respondents. The 0bserved variables were financial performance and trends in cooperative financial. The results revealed that 30% of dairy cooperatives had effective financial performance. Average trends of dairy cooperative financial which based on liquidity ratios, solvency ratios, and profitability ratios tend to decrease each year. Based on the SWOT analysis, there are several strategies that can be applied to improve financial performance of dairy cooperatives, namely 1) increasing the productivity of business units on an economic scale by utilizing government loans and GKSI support, 2) raising awareness of the importance of the role of members through fostering skills and strengthening the roles and functions of livestock group. The strengthening strategies for cooperatives with ineffective financial performance are 1) efficiency of production operational costs and adding equity by utilizing government assistance to reduce the burden of cooperative debt, 2) optimizing productive business units.

The improvement in the design of mordenite-based catalysts focuses on the present study to fulfill the massive demand for bio-aviation fuel (BAF) as renewable energy. Modification of the mordenite through ionic impregnation of Fe, Cu, and Cr, has supported the mordenite to perform with better efficiency and activity in catalyzing the cracking process of stearic acid. The adjustment on catalytic activity was carried out by simply reacting the catalyst with stearic acid at 190 °C and investigating cracking products with Gas Chromatography-Mass Spectroscopy. The results of the GC-MS test of the cracking product showed the formation of alkane-alkene and aromatic compounds. BAF was selectively obtained (30.27%) when the reaction was catalyzed by FeCuCr/mordenite catalyst. The BAF derived from FeCuCr/mordenite contained hydrocarbons that include xylene, mesitylene, dodecane, tridecane, tetradecane, and pentadecane. However, reduced selectivity was realized (19.85%) when the reaction was catalyzed by nano FeCuCr/mordenite. Its hydrocarbon constituents include benzene, tetradecane, and pentadecane compounds.

The Coronavirus that is present in society in 2020 is attracting attention. The visible impact does not only affect public health but also affects the country’s economy. Even today the world economy is under heavy pressure due to this virus. The topic this time will discuss the global impact of the presence of the coronavirus or its scientific name is referred to as COVID-19. The research method used is descriptive qualitative by describing the phenomena and existing literature. The results of this study indicate that seeing economic developments and influences is not limited to the scope of the economy itself. However, the economy can also be affected by culture and health. This is evidenced by the spread of the Coronavirus which has harmed the world economy.

The aim of this research is to get information of heavy metal content of Pb in goat milk fed with vegetables waste silage which is safe to be consumed by society. The experiments were carried out by using 16 pregnant 2 - 2,5 years old goat who were treated until the mother was lactated. The experimental design used was Completely Randomized Design with 4 treatments and 4 replications. The treatments applied were as follows: T0 = 100% forage (mixture of grass and legume), T1 = 80% forage + 20% vegetables waste silage, T2 = 60% forage + 40% silage vegetables waste, and T3 = 40% forage + 60% waste silage vegetables. The experiment was conducted for 5 months. The research results show that the feed silage vegetables waste very real produce milk production daily higher than the control of grass. The provision of silage vegetables waste very real produce metal Pb levels higher than control and be above threshold SNI 3141.1: 2011. So that it can be concluded that the silage vegetables waste not advisable done by farmers due to metal Pb in goat milk is still not safe to be consumed. Keywords : Silage, Vegetables Waste, Pb, Goat Milk.

Penelitian ini dilaksanakan di PT. AS Putra Group Kuningan, mulai tanggal 8 Maret sampai dengan 10 April 2021. Penelitian ini bertujuan untuk mengetahui analisis usaha ayam ras petelur dengan sistem kandang berbeda yaitu kandang sistem open house dan sistem close house. Metode penelitian yang digunakan adalah survei dibantu dengan kuesioner. Berdasarkan hasil penelitian di PT. AS Putra Group Kuningan selama satu periode produksi (14 bulan) pendapatan usaha sistem close house Rp 8.251.431.862 dengan skala usaha 92.000 ekor daripada sistem open house Rp 4.139.136.605,15 dengan skala usaha 57.000 ekor atau keuntungan per ekor pada kandang close house sebesar Rp 89.689 > Rp 72.616 pada kandang open house. Berdasarkan hasil perhitungan dari dua sistem pemeliharaan didapat nilai R/C rasio kandang close house sebesar 1,30 > 1,23 pada kandang open house, B/C rasio kandang close house sebesar 0,30 > 0,23 pada  kandang open house, BEP produksi pada kandang close house sebesar 1.294.538,7 kg dan 847.897,5 kg pada kandang open house, BEP harga pada kandang open house sebesar Rp 17.622,2 > Rp 17.552,6 pada kandang close house dan PP kandang  open house sebesar 2,2 periode yaitu 30,8 bulan < 2,65 periode atau 37,1bulan pada kandang close house. Meskipun kandang close house lebih lama 6,3 bulan PP nya namun karena umur ekonomisnya lebih lama (20 tahun) dibandingkan open house (10 tahun) maka kandang close house lebih menguntungkan. Dari hasil analisis maka dapat disimpulkan bahwa usaha ayam ras petelur di PT. AS Putra Group Kuningan lebih menguntungkan dengan sistem close house.

Tujuan dari penelitian ini untuk mengetahui alur rantai pasok dan mengetahuimarjin pemasaran. Penelitian ini menggunakan metode analisis deskriptifkuantitatif dan sumber pengumpulan sumber pengumpulan data adalah data primer,teknik pengumpulan data yang digunakan dengan cara survey. Penentuan sampelpada penelitian ini menggunakan teknik sampling snowball sebanyak 20 orangyang terlibat dalam rantai domba di Kecamatan Kertajati, Hasil penelitian inimenenjukan bahwa rantai nilai pemasaran di Kecamatan Kertajati memiliki nilaitertinggi pada Peternak domba Petet dan Dara. Karena itu hasil penjualan dombapetet dan dara dianggap sebagai keuntungan. Keuntungan rata-rata dari Peternakdomba petet Rp 1.000.000/ekor, dan untuk domba dara Rp 1.300.000/ekor.Sedangkan dari keseluruhan pelaku rantai pasok terletak pada pedagang dombasebesar Rp 500.000/ekor, karena pedagang tidak memerlukan biaya yang terlalutinggi, sedangkan harga di pengaruhi oleh permintaan di tingkat konsumen. Untukpelaku rantai pasok Bandar memiliki keuntungan sekitar Rp 100.000 s/d Rp200.000/ekor. Dan pelaku rantai Pasar memiliki keuntungan sekitar Rp 50.00 s/dRp 100.000/ekor.
