THE USE OF COCONUT WATER FOR RAW MATERIAL OF VINEGAR
Get PDFVinegar could be produced from any fruit juice. Coconut water as raw material was used by increasing sugar concentration. Vinegar is one of the alternatives in the use of coconut water waste. This is supported by the needs of the growing vinegar. Vinegar manufacture involves two stages of fermentation (anaerobic and aerobic). Aerobic fermentation by adding yeast and sugar yield of 12% alcohol (the alcohol optimal), where as aerobic fermentation produces vinegar 4% -12.5% (SNI). The purpose of this study were to determine the optimal percentage of the addition of yeast and sugar to produce alcohol 12%, and to compare the quality of coco vinegar with SNI 01-3711-1995 vinegar. This study used factorial completely randomized design , the adding sugar and yeast as treatment, 3 level of adding sugar and yeast with 3 observations. Results of variance analysis showed that the treatment was very real effect on levels of alcohol and alcohol pH. The Duncans Multiple Range Test (DMRT) showed that the highest quality levels of alcohol present in addition of 16% sugar and 6% of yeast. while the pH of alcohol contained in the addition of yeast 4.5% and sugar 10
PERFORMANCE OF “PACKAGED” AND STANDARD PALM OLEIN OIL IN FRYING KERUPUK JALIN
Get PDFThe objective of the study was to evaluate the changing pattern of free fatty acid (FFA) and smoke pints of packaged and standard palm olein oil in frying kerupuk jalin. The other objective was to determine the end use of both frying oils during deep fying of kerupuk jalin. Continous deep frying with three replicates had been done for10 hours using special grade and regular frying oil without the addition of fresh oil during frying study. The result indicated that The FFA content of both packaged and regular oils increased linearly with increasing frying time, up to 10 hours. In addition, smoke point of the oils decreased linearly with increasing frying time. Based on FFA of the oil, the packaged oil could last 1,4 longer than regular oil during frying of kerupuk jalin.

Get PDFExperiment on catfish drying employing ‘Teko Bersayap’ solar dryer was conducted. The result of the experiment indicated that the dryer was able to increase ambient temperature up to 44% and decrease ambient relative humidity up to 103%. Fish drying process followed equations : KAu = 74,94 e-0,03t for unsplitted fish and KAb = 79,25 e-0,09t for splitted fish, where KAu = moisture content of unsplitted fish (%), KAb = moisture content of splitted fish (%), t = drying time. Drying of unsplitted fish finished in 43.995 hours while drying of split fish completed in 15.29 hours. Splitting the fish increased 2,877 times drying rate

KELAYAKAN TEKNIS DAN FINANSIAL PEMBUATAN BIOBRIKET DARI LIMBAH PADAT KELAPA SAWIT DENGAN METODE PENGARANGAN
Get PDFThis research was conducted at the Laboratory of Agricultural Technology, University of Bengkulu and Laboratory of PT Sucofindo Bengkulu, from May until August 2009. This study compared three types of biobriquettes such as the biobriquettes made of shell charcoal, coal-mixed TTKS charcoal biobriquettes, and coal-mixed TKKS charcoal with carbonized-coal briquettes. The results showed that, technically, biobriquettes has cylindrical dimension with a diameter of 4.5 cm, height 7 cm, lower hole diameter 1.5 cm, and upper hole diameter 1.2 cm. Biobriquette made of TKKS charcoal is very feasible to use as used as a fuel in compare to carbonized-coal briquettes, since TKKS charcoal biobriquette contains 7, 3 % water and the average calorific value of 6141 kcal / kg. Financially, the manufacturing on these three types of palm oil waste briquettes is very feasible because it has R/C value > 1. However, if these three types compared, coal-mixed TTKS charcoal biobriquettes is preferable because it has R/C value 1,78 with break-even-point (BEP) 24.468 kg/ year, which is better than biobriquettes made of TKKS charcoal and shell charcoal

PEMBUATAN MIE BASAH BERKALSIUM DENGAN PENAMBAHAN TULANG IKAN TENGGIRI (Somberomorus lineolatus)
Get PDFMie merupakan produk makanan yang sangat populer dan banyak dikonsumsi oleh masyarakat Indonesia. Namun ternyata mie bukanlah merupakan makanan yang dianggap istimewa, hal ini terjadi karena umumnya kandungan gizi produk mie dan olahannya masih rendah, terutama kandungan protein dan mineralnya (Prananto, dkk.2003). Bila ditinjau dari segi nilai gizi, mie sarat akan karbohidrat dan zat tenaga (energi) dengan kandungan protein yang relatif rendah. Kandungan gizi mie sangat bervariasi, tergantung pada jenis, jumlah dan kualitas bahan penyusunnya, serta cara pembuatan dan penyimpanannya. (Astawan, 2005). Salah satu bahan yang dapat meningkatkan nilai gizi mie adalah tulang ikan tenggiri. Unsur utama dari tulang ikan tenggiri terdiri dari kalsium, fosfor, dan karbonat sedangkan yang terdapat dalam jumlah kecil adalah magnesium, sodium, fitat, klorida, sulfat, strontium. Persantase berat kalsium pada ikan secara umum adalah 0,1 – 1,0%, dimana rasio kalsium dan fosfor adalah 0,7 – 1,6% (Anonim, 2007). Penelitian ini bertujuan untuk mengetahui tingkat kesukaan panelis terhadap mie basah dengan penambahan tepung tulang ikan tenggiri serta menentukan mutu kimia mie basah yang meliputi kadar air, dan kadar kalsium. Hasil penelitian memperlihatkan bahwa penambahan tepung tulang ikan tenggiri pada pembuatan mie basah menyebabkan tingkat penerimaan panelis yang berbeda nyata pada warna dan aroma, sedangkan kelengketan dan tekstur berbeda tidak nyata. Mie basah yang paling disukai adalah perlakuan dengan penambahan 10%. Kadar air mie yg paling disukai panelis masih memenuhi nilai standar yaitu sebesar 24,5%, serta kadar kalsium dapat meningkat sebanyak 4,53% bila dibanding perlakuan kontrol
KAJIAN PEGGUNAAN BERBAGAI JENIS BIOBRIKET SEBAGAI ALTERNATIF PENGGANTI MINYAK TANAH UNTUK RUMAH TANGGA
Get PDFBiobriquet defined as fuel and solid which came from organic rested material. The formation of biomass into biobriquet intended to facilitate its utilizing. The use of biobriquet as alternative energy can replace the use of kerosene for burning needs in the household. This research is aimed to determine the best type of biobriquet based on the quality of burning performance produced by kerosene control and determine life time of biobriquet that have been packaged on plastic and paper bags that saved in temperature room. This research was conducted in the Laboratory of Agricultural Technology, Faculty of Agriculture,UniversityofBengkuluand PT Sucofindo Bengkulu. It examined four types of biobriquet which are palm shell charcoal biobriquet (A), Empty fruit bunch (EFB) charcoal + coal biobriquet (B), EFB charcoal biobriquet (C) and non-choarcoling oil palm shells biobriquet (D). Observed variables are the calorific value, moisture content, ash content, levels of substance to fly, lighting time, burning time, Water Boiling Test (WBT), Control Cooking Test (CCT), intensity of smoke, and water content changes in packaging of biobriquet. The results showed that non-choarcoling palm oil shells biobriquet (D) is the best biobriquet based on performance quality. If it compared with kerosene, non-choarcoling palm oil shells biobriquet (D) is better than kerosene, while in other biobriquets, kerosene is still the best one. Based on other biobriquet tests (water content, calorific value, ash content, levels of substance to fly, lighting time, burning time and fuel consumption biobriquet), the best biobriquet that replaced kerosene is TKKS charcoal biobriquet (C), however, for the variables which compared with kerosene (burning time and fuel consumption), kerosene is still the best one. Biobriquet that packaged by using paper bags for 6 weeks the rising of water levels are relatively low compared with the plastic bags
