Abstract

Eucheuma cottonii is red algae that contain high carbohydrates, especially carrageenan. Carrageenan is a sulfated polygalactan with 15-40% of ester-sulfate content. It is formed by alternate units of D-galactose and 3,6-anhydro-galactose joined by α-1,3 and β-1,4-glycosidic linkage. The galactose polymer therein can be hydrolyzed into Galactooligosaccharide (GOS)type prebiotics. Hydrolysis was done by low concentration of sulfuric acid and crude enzyme from inactivation of Vibrio algynoliticus cell broth. Combination of prebiotic and probiotic provide lactic acid bacteria (BAL) as well as its food sources in the colon. The aim of this research is to know the characteristics of BALgrowth and fermentation in hydrolysateof E. cottonii and to know the best method in producing synbiotic powdersfrom BAL grown in hydrolysate. Analysis conducted include the characteristics of synbiotic powders using two types of BAL, namely Lactobacillus casei and kefir bacteria (Lactobacillus spp.). Characteristics of the two types of BAL produced during fermentation were qualified as probiotics which were amounted to more than 108 cell/mL, pH value <4.5, and total acid> 0.2%. The results showed that the number of living bacteria was higherin the method of synbiotic productions after dryingof hydrolysates followed by inoculum addition, than the method of synbiotic productions which inoculum addition was donebefore drying. Keywords:Eucheuma cottonii, Lactobacillus casei,Lactobacillus spp.in kefir

Abstract

Tooth and mouth disease that is suffered by many people is the reason for the increasing usage of mouthwash. Mouthwash on the market contains alcohol which causes side effects. The purpose of this study is to develop mouthwash concentrate based on essential oil (betel leaves and cloves) that can be accepted by prospective consumers, and to analyze the eligibility criteria of the mouthwash industry investment. The respondents 100 peoples, ranging in 15 to 62 y.o including visitors at Botani Square Mall, Sempur Field, Bhayangkara Hospital Bogor, and IPB students. The research uses an action research approach including market identification, prototype design, research and development, product acceptance analysis and financial analysis. Some problems raised from respondent interview were the side-effects of product, no measuring cup attached, less practical package, and the price was not affordable. The research solution was a practical 30 mL prototype of bottle drops with measuring cap. The production cost was IDR 6,808 and selling price (based on customer willingness to buy) of IDR 20,000. The result also showed a good acceptance of product by most respondents. Based on financial analysis, this product was concluded as feasible for industrial implementation. Keywords: alcohol mouthwash, betel-clove essensial oils, financial analysis, mouthwash industry

Abstract

Oksigen digunakan sebagai penyempurna reaksi pembakaran dalam mesin. Reaksi pembakaran yang sempurna dapat menghemat konsumsi bahan bakar. Umumnya, oksigen berasal dari udara yang masuk kedalam sistem pembakaran. Minyak atsiri merupakan senyawa hidrokarbon oksigenat yang kaya akan oksigen. Tujuan penelitian ini adalah mendapatkan komposisi dan konsentrasi terbaik dari penambahan bioaditif ke dalam solar yang mampu menurunkan konsumsi spesifik bahan bakar biosolar. Penelitian ini meliputi pencampuran bahan bioaditif yang terdiri dari eugenol-sitronellal, eugenol-minyak sereh wangi, dan sitronellal-minyak daun cengkeh dengan komposisi formulasi 1:1 dan dicampurkan ke dalam bahan bakar dengan konsentrasi pencampuran 0.1%, 0.5 %, dan 1.0 % serta dilakukan pengujian karakteristik bahan bakar yang meliputi densitas, viskositas, dan nilai kalor serta pengujian performa mesin. Formulasi yang menunjukkan adanya penghematan konsumsi bahan bakar pada putaran daya maksimal adalah formulasi eugenol-sitronellal 0.1 % , 0.5 %, dan 1.0%,  Eugenol-minyak sereh wangi 0.1 % dan 0.5 %, Sitronellal-daun cengkeh 0.1 % dan 1%. Formulasi terbaik untuk menurunkan laju konsumsi spesifik bahan bakar adalah Eugenol-sereh wangi dengan konsentrasi 0.1 % yang dapat menurunkan laju konsumsi spesifik sebesar 7.55%
