Abstract

Ubi jalar mengandung beberapa jenis oligosakarida yang mungkin berfungsi sebagai prebiotik, dan diharapkan setelah proses pengolahan, fungsi daari prebiotik dapat dipertahankan. Penelitian ini dilakukan dengan tujuan untuk melakukan uji in vitro dan in vivo ekstrak ubi jalar sebagai prebiotik. Pengujian efektifitas sari ubi jalar terhadap pertumbuhan Bakteri asam laktat dilakukan menggunakan media de Mann Rogosa sharpe broth (MRSB), dengan perlakuan K (-): MRSB sebagai kontrol negatif; K (+) : MRSB + BAL sebagai kontrol positif ; P1 : MRSB + BAL + sari ubi jalar Sukuh ; P2 : MRSB + BAL + ari ubi jalar Betta-1 dan P3: MRSB+ BAL + sar ubi jalar Antin. Pengujian in vivo dilakukan dengan menguji pertumbuhan bakteri asam laktat (BAL) dan uji kompetisi pertumbuhan BAL dan Escheria coli (E.Coli) terhadap ekstrak ubi jalar yang terbaik dari hasil uji in vitro sebelumnya. Uji in vivo dilakukan dengan menggunakan 4 kelompok tikus percobaan, yang masing-masing terdiri dari 4 ekor tikus putih jantan galur Sprague-dawley berumur dua bulan. Berdasarkan hasil uji vitro menunjukkan ekstrak ubi jalar semua varietas memiliki nilai absorbansi yang semakin tinggi pada 0 dan 24 jam dengan panjang gelombang 660 nm. Hal tersebut menunjukkan ekstrak ubi jalar pada dapat menstimulir pertumbuhan BAL dengan baik. Ekstrak ubi jalar dapat menekan pertumbuhan E. Coli dan Menstimulir BAL terutama ubi jalar varietas Betta-1 dan Sukuh. Hasil uji in vivo menunjukkan ekstak ubi jalar pada dosis pemberian ekstrak ubi jalar 0,54 g/hari dan 1,08 g/hari belum efektif meningkatkan bekteri asam laktat fekal dan menekan pertumbuhan bakteri asam laktat E. Colli tikus percobaan.

Abstract

Dalam kegiatan produksi, industri pangan selalu menghasilkan limbah, baik berupa limbah padat, limbah cair maupun gas. Salah satu cara pengolahan limbah cair indutri pangan adalah dengan cara biologi, menggunakan mikroorganisme selektif sesuai dengan karakteristik limbah industri pangan yang diolah. Pada kegiatan ini telah dilakukan penelitian penggunaan beberapa jenis starter yang berasal dari lumpur limbah cair yang bersala dari industri tahu, bihun dan roti. Penelitian ini bertujuan untuk mendapatkan produk starter mikroorganisme siap pakai dengan biaya murah. Penelitian dilakukan dengan menggunakan 3 faktor yakni A,B dan C dimana faktor A adalah jenis limbah cair, yaitu limbah cair industri tahu, limbah cair industri bihun dan limbah cair industri roti. Faktor B adalah jenis starter yang digunakan yakni lumpur aktif/sludge, phenobac dan kontrol. SEdangkan faktor C adalah waktu inkubasi, 0,2m4 dan 6 hari. Hasil penelitian menunjukkan bahwa lumpur aktif dari industri bihun dapat digunakan untuk mengolah limbah industri pangan lainnya. Tingkat penurunan BOD tertinggi adalah perlakuan limbah cair industri tahu dengan menggunakan lumpur aktif industri bihun selama 6 hari dapat menurunkan BOD dari 2667,4 mg/l menjadi 941,2 mg/l (64,71%). Untuk TSS tingkat penurunan tertinggi adalah air limbah bihun penuruan TSS sebesar 83,23%.

Abstract

Chitosan is biopolymer  that occur by treatment of chitin deactylation process, with strong alkali. Chitosan may be used in treating turbid matter in aqueous solution to help remove the turbid matter. Chitosan is used as a viscosity enhancer to settle solids suspended in liquids. Chitosan offers a good volume reduction of waste water, which is an essential requirement for water recovery and poilution prevention.

Abstract

Nowadays, the use of natural plant source insecticides in one of the best chosen due to its characteristic, which of safer and easily degradable by nature (biodegradable) compared to synthetic materials. One of plant sources wiich consists of active components for insecticides is neem plant. This study aimed to determine the effect of extraction of active ingredients of neem seeds and leaves by fermentation using Effective Microorganisms (EM4). The Extraction of seed and leaf neem to produce neems active compound was conducted by using Effective Microorganisms. The efficacy test of the neem seed and leaf was conducted by using fermented extract concentrated of 3% and 6% and observed with interval of 2 to 6 days. The formula used in this experiment which A as raw material and B as concentration of Effective Microorganisms are A1 as neem;s seed, A2 as neems leaves; and B as concentration of effective microorganisms which is B1 as 3 %, concentration and B2 as 6 % concentration. The extraction product were evaporated with rotary vacuum evaporator. The extracts obtained were tested their solubility. Azadirachtin were obtained on combination od A1B2 for neem,s seeds for 6 days fermentation period which acquired 1313,23 ppm (61,25 %) of azadirachtin and combination of A2B2 for neem;s leaves which acquired 665,69 ppm (69,17%) of azadirachtin from raw materials. The active compounds were tested their ability as insecticide and showed that 50 ppm of azadirachtin concentration still effective for 14 days evaluation.

Abstract

 The cacao production in Indonesia was increased very rapidly in the last five years. However, almost all of the cacao production in Indonesia was exported as cacao bean, meanwhile there were only a few of cacao processing industry top process the cacao bean become chocolate products. These condition was not advantaging for cacao and chocolate industry development, because the added value of cacao bean was small. Therefore, it was needed a strategic development of cacao products. In this case , divesrsification of cacao products for small scale industry was one of the alternative strategic for cacao product development. The study aimed at designing and engineering a set of equipment for small scale industry and material formulation for grain chocolate production. It was concluded that designing and engineering a set of grain chocolate equipment could be implementation for small scale industry by modification. The capacity of cacao granulator ia 4,16 kg per hour. Efficiency of the granulator is 74,8% and the temperature in the cooling tunnel is 10 - 12 C. The grain cocoa product is fullfilled the requirement of Indonesia National Standard (SNI), however the texture and appearance is still have to be improved.

Abstract

In order to support food diversification, the effort to increase value-added sweet potatoes, which are very abundant in Indonesia, is necessary to conduct. Therefore, the research was conducted to study the content of oligosacharide from various cultivars of sweet potatoes, to develop formulation and to examine consumen acceptance of sweet potatoes drink. The steps of the research were consisted of production of sweet potatoes flour, extraction of oligosacharide, analysis of oligosacharide content, production of sweet potatoes drinks and its organoleptic test.Sweepotatoes flour were made by slicing the tuber, drying at 55 -60 C for plus minus 20 hours, grinding and shieving with mesh 80. The flour extraction was done usinng ethanol 70% for 15 hours and then evaporated using rotary evaporator. The oligosacharide content was analyzed by thin layer chromatography and HPLC. Sweet potatoes drink were produced as follow : size reduction, blanching, water addition with ration flour ti water of 1:2, filtering to separated the starch and formulation.The result showed that the highest oligosacharides content was white sweet potatoes with rafinose content 0,15%, 0,02% stachiose, dan 0,11% malthohexose, while the highest oligosacharide content of sweet potatoes drink was red sweet potatoes with 0,07% rafinose. Hedonic test showed that red sweet potatoes drink with 10% sugar and 0,1% citric acid was the most prefered with average score for taste, color were 3.50 and for flavor was 3.45.
