Pemacu Pertumbuhan Alami pada Broiler
Get PDFThe study aimed to determine the effect of probiotic, prebiotic and eubiotic addition on broilers to the appearance of broiler production. The material used was 100 broiler chickens, which were kept since the Old Chicks Day until the age of 4 weeks and distributed in 4 groups, namely probiotics, prebiotic and eubiotics. The research method was experimental compiled based on Completely Randomized Design (CRD) with 4 treatments and 5 replications. The treatments in ji are as follows: control group (without any addition), probiotics, prebiotic and eubiotic. The variables observed in this study are feed consumption; weight gain (PBB); feed conversion; carcass weight, carcass and mortality. The data obtained were analyzed using variance analysis and if there were differences between treatments. The results showed that the addition of probiotics, prebiotic and eubiotics increased weight gain, and increased consumption and were able to reduce the ration conversion value Keywords: Growth booster, broiler Disubmit : 13-08-2018; Dite
Pengaruh Kebijakan dan Faktor Penentu Impor Bawang Putih Indonesia dari Cina
Get PDFThe government has targeted garlic self-sufficiency in 2021 to meet the national demand for garlic. However, most of Indonesia's garlic needs are still met by importing garlic from garlic-producing countries. This study aims to analyze the influence of policies and determinants of Indonesian garlic imports from China as the largest garlic exporter in Indonesia and globally. This study analyzes the annual time series data from 1996 to 2019 using multiple linear regression with the Ordinary Least Square (OLS) method. This study found that the tariff elimination policy significantly affected the volume of garlic imports from China. Imported garlic prices, Indonesian population, and domestic shallot prices also significantly affect the volume of Indonesian garlic imports from China. Meanwhile, the RIPH policy and the real exchange rate did not significantly affect Indonesia's garlic imports from China.Pemerintah telah menargetkan swasembada bawang putih di tahun 2021 guna memenuhi permintaan bawang putih nasional. Namun demikian, sebagian besar kebutuhan bawang putih Indonesia masih dipenuhi dengan mengimpor bawang putih dari negara produsen bawang putih. Penelitian ini bertujuan menganalisis pengaruh kebijakan dan faktor penentu impor bawang putih Indonesia dari Cina sebagai negara eksportir bawang putih terbesar di Indonesia dan dunia. Penelitian ini menganalisis data time series tahunan dari tahun 1996 sampai 2019 menggunakan regresi linier berganda dengan metode Ordinary Least Square (OLS). Hasil penelitian ini menemukan bahwa kebijakan penghapusan tarif memengaruhi volume impor bawang putih dari Cina secara signifikan. Harga bawang putih impor, populasi Indonesia, dan harga bawang merah domestik juga memengaruhi volume impor bawang putih Indonesia dari Cina secara signifikan. Sedangkan kebijakan RIPH dan nilai tukar riil tidak memengaruhi impor bawang putih Indonesia dari Cina secara signifikan

Synthesis, Characterization and Antibacterial Activity Assay of Carboxymethyl Chitosan
Get PDFChitosan is a natural biopolymer with the second largest abundance after cellulose. This compound was obtained from the deacetylation of chitin from crab shell waste obtained in province of Lampung. It is known that chitosan has antibacterial properties because it has an amino group. However, a modification process needs to be carried out to produce compounds with more specific properties and benefits. The purpose of this study was to synthesize and to determine the characterization and antibacterial activity of carboxymethyl modified chitosan. Based on the research results obtained as much as 10.24% chitosan (per weight of crab shell powder) and carboxymethyl chitosan as much as 72.9% (per weight of chitosan). FTIR analysis of the derivative confirmed the incorporation of the carboxymethyl groups. Chitosan has a water content of 0.49% while carboxymethyl modified chitosan has a water content of 0.67%. The ash content of chitosan was 0.33% and the ash content of carboxymethyl modified chitosan was 0.69%. The synthesized chitosan has antibacterial activity against E.coli bacteria with the inhibition zone of 10 mm while against S. Aureus it had an inhibition zone of 11.89 mm. Meanwhile the inhibition zone of carboxymethyl chitosan against E.coli bacteria was 11.50 while that for S. Aureus was 12 mm
STUDI PENDAHULUAN PRODUKSI NITRAT SEBAGAI BAHAN BAKU PUPUK DENGAN METODE PLASMA DISCHARGE
Get PDFNitrogen-based fertilizer production mainly involves the Haber-Bosch process, which synthesizes Ammonia via a chemical reaction of N2 from the air and H2 under high temperature and pressure conditions in the presence of a catalyst. However, the environmental concern for greenhouse gas emissions and high energy consumption triggers other Nitrogen fixation method development. The non-thermal plasma oxidation of N2 into Nitrate is a promising method since it has lower energy consumption and a more suitable process condition with a better environmental profile. This study tested the designed plasma discharge reactor tube to produce nitrate from air N2 with varying voltage, time, and airflow rate operating conditions. Nitrate concentration was analyzed using a UV-Vis spectrophotometer. The results show that nitrate concentration changes linearly with the applied voltage in a constant airflow rate and length of treatment time. The highest performance of the plasma discharge reactor was achieved on a 6 kV applied voltage with a flow rate of 0.2 L/min and a treatment time of 40 minutes where the obtained nitrate concentration was 7.7 ppm, which indicated the potential plasma discharged nitrate production for green fertilizer application. Further study shall be carried out to enhance the performance.Produksi pupuk berbasis nitrogen umumnya melibatkan proses Haber-Bosch, dimana sintesin ammonia dilakukan melalui reaksi kimia N2 dari udara dan H2 dengan suhu dan tekanan tinggi serta bantuan katalis. Namun, kepedulian lingkungan terhadap emisi gas rumah kaca dan konsumsi energi yang tinggi memicu pengembangan metode fiksasi Nitrogen lainnya. Oksidasi plasma non-termal N2 menjadi Nitrat adalah metode yang menjanjikan karena memiliki konsumsi energi yang lebih rendah dan proses yang lebih sesuai dengan kondisi lingkungan yang lebih baik. Penelitian ini menguji reaktor plasma discharge yang dirancang untuk menghasilkan nitrat dari N2 di udara dengan memvariasikan parameter tegangan, waktu, dan laju aliran udara. Konsentrasi nitrat dianalisis menggunakan spektrofotometer UV-Vis. Hasil penelitian menunjukkan bahwa konsentrasi nitrat berubah secara linier dengan tegangan pada laju aliran udara dan waktu yang konstan. Kinerja tertinggi reaktor plasma discharge dicapai pada tegangan 6 kV dengan laju alir 0,2 L/menit dan waktu perlakuan 40 menit dimana konsentrasi nitrat yang diperoleh adalah 7,7 ppm, yang menunjukkan potensi plasma discharge dalam memproduksi nitrat yang berpotensi sebagai untuk bahan baku pupuk yang ramah lingkungan. Penelitian lebih lanjut perlu dilakukan untuk meningkatkan kinerja dari reaktor plasma discharge
