Improvement of Napier Grass Silage Nutritive Value by Using Inoculant and Crude Enzymes From Trichoderma Reesei and Its Effect on in Vitro Rumen Fermentation

This research was aimed to evaluate the effect of inoculant and crude enzyme of Trichoderma reesei on fermentation quality and rumen digestibility of napier grass silage. This research consisted of two stages. The first stage was fermentation quality using a completely randomized design with three treatments and six replications. The second stage was rumen fermentability using a randomized block design with three treatments and six replications. The treatments of both stages were: T0= control of napier grass silage (Hi-fer+), T1= control + T. reesei inoculant at the level of 2.13 x 107 cfu/kg, and T2= control + crude enzyme from T. reesei at the level of 11.4 unit/kg. Napier grass silage were kept at room temperature and opened 21 d after fermentation. The result of the first stage experiment showed that T2 decreased (P<0.01) dry matter, organic matter, crude fiber, and neutral detergent fiber (NDF) and also increased (P<0.05) crude protein, total digestible nutrient (TDN), pH, acetic acid, and propionic acid of napier grass silage while T1 decreased (P<0.01) NDF and increased (P<0.05) propionic acid. The result of the second stage experiment showed that there were no significant differences in rumen pH, in vitro dry matter and organic matter digestibility, total VFA, proportion of VFA, ratio of acetic to propionic acids, and also NH3. It is concluded that the addition of crude enzyme from T. reesei could improve fermentation quality of napier grass silage with decreasing NDF and increasing TDN but did not affect rumen fermentability

Pengaruh Penggunaan Antibiotik Eritromisin Dengan Terapi Calcium-channel Blocker Terhadap Gagal Ginjal Akut

Calsium-Channel Blocker (CCB) seperti amlodipin, felodipin, nifedipin, diltiazem, dan verapamil dimetabolisme oleh enzim CYP3A4. Kadar CCB dalam darah dapat meningkat ke level yang berbahaya jika enzim tersebut dihambat. Eritromisin (antibiotik makrolida) merupakan inhibitor CYP3A4, penggunaan bersamaan CCB dan makrolida diasosiasikan dengan peningkatan risiko rawat inap akibat gagal ginjal akut. Tujuan penelitian ini untuk mengetahui pengaruh yang ditimbulkan oleh penggunaan CCB dan eritromisin terhadap fungsi ginjal pada pasien rawat inap poliklinik penyakit dalam RS Dr. Moewardi. Penelitian dilakukan secara deskriptif dengan pendekatan pengambilan data secara retrospektif. Data diperoleh dari hasil observasi catatan rekam medik pasien selama menjalani perawatan di rumah sakit (rawat inap). Hasil dari 4 pasien diketahui masing-masing pasien mengalami peningkatan kadar kreatinin dan ureum dengan rata-rata kenaikan kreatinin 34,8% dan ureum 36,6%. Hal ini kemungkinan disebabkan adanya interaksi makrolida dan CCB yang mengakibatkan kenaikan kadar CCB dalam darah sehingga menyebabkan hipotensi. Keadaan hipotensi dapat menyebabkan hipoperfusi ginjal yang berpotensi terjadinya gagal ginjal akut, dimana ditandai dengan meningkatnya kadar ureum dan kreatinin

Pengembangan Sistem Informasi Akademik pada SMPN 36 Bandung

Akademik merupakan salah satu bentuk kegiatan dibidang pendidikan, sisteminformasi akademik di SMPN 36 Bandung dinilai belum efektif dimana pencatatan data siswa, data guru, data nilai dan penjadwalan masih dicatat dalam pembukuan sehingga mudah rusak atau hilang serta pembuatan laporannya memakan waktu yang lama. Penelitian ini bertujuan untuk mengetahui sistem yang sedang berjalan, membuat perancangan dan mengembangkan sistem informasi akademik yang diusulkan.Dalam pengembangan sistem informasi akademik penulis menggunakan metode pendekatan terstruktur dengan menggunakan alat bantu berupa data flow diagram serta entity relathionship diagram. Metode pengembangan menggunakan metode prototype. Bahasa pemograman yang digunakan dalam mengembangkan sistem informasi akademik adalah java netbeans dan database yang digunakan adalah mySQL.Melalui hasil dari penelitian di SMPN 36 Bandung yang berupa sistem informasi akademik diharapkan dapat membantu bagian Tata Usaha dalam mengelola data siswa, data guru, data nilai dan penjadwalan lebih cepat dan dapat mengurangi kesalahan dalam proses pencatatan data serta mengurangi kesalahan dalam penyampaian laporan

Pengemasan Produk Sayuran Dengan Bahan Kemas Plastik Pada Penyimpanan Suhu Ruang Dan Suhu Dingin

Agricultural Product (both of raw material and intermediate good/ food) has limited durability before perish process. It relates with physicalcharacter of them, different with physical character of industrial product.The physical character are perishable , bulky, and voluminous. Onealternative that could be done, for fresh and good product when it is givento consumer is packing. Type of packing materials e g : plastic, glass,paper, and styrofoam. There are many packing technique : common,vacuum and press. From permeability calculation, is known if bahwa permeability of polypropylen plastic is bigger than polyethylen plastic. It isdeviation, because of polypropylene permeability must be lower thanpolyethylene. For application test on water spinach, permeability ofpolypropylen plastic is lower than polyethylen. The different ofPermeability on polypropylen and polyethylen packing impacts on weight,color, and texture of water spinach leaf. While on cold temperature packing,polypropylene plastic is better than polyethylene as material packing

This study aimed to examine the effects of the investment risk, return on equity (ROE), and proceeds on underpricing and also to test underwriter\u27s reputation as a moderating variable and how its influences the independent variables. The population in this study is a non-financial companies are experiencing underpricing in initial public offering (IPO) at the Indonesian Stock Exchange (IDX) in the period 2010-2014, which amounted to 86 companies. The amount of samples are 73 companies that were taken by using purposive sampling method. The type of data in this research is secondary data, which is the prospectus that published by the company. In terms of data analysis, this study using moderate regression analysis (MRA) with SPSS 21.0. The results of this study showed that: 1) the risk of investment have a negatif influence and significant impact to underpricing with coefficient value 4,606, 2) ROE have a negatif influence and significant impact to underpricing with coefficient value 1,342, 3) proceeds having a negatif significant influences too towards underpricing with coefficient value 4,953. After moderated by underwriter reputation variable, only investment risk and proceeds that have a significant effect on underpricing. For simultaneous effects, all variables are significantly influence the underpricing with 38,8% coefficients determination value
