Abstract

The study of the formulation of desiccated coconut biscuits by roasting and without roasting was investigated. This research was conducted using randomized block design consisted of two factors and three replications. The first factor is the percentage of the desiccated coconut addition to wheat flour with three levels (25%, 50% and 75%). The second factor is the variation treatment of the desiccated coconut; roasting and without roasting. The result showed that the percentage of desiccated coconut addition to wheat flour has a significant effect on protein content. The treatment of roasting and without roasting has very significant effect on the peroxide number and significant effect on the moisture content, sensory test (aroma and taste). The interaction factor between the percentage of desiccated coconut addition to wheat flour and the treatment of roasting and without roasting has a very significant effect on the fat content and has a significant effect on the sensory test (aroma and taste). The best formulation of the desiccated coconut biscuits based on the sensory test was obtained from the addition of75% of desiccated coconut without roasting.

Abstract

Tomato fruit undergoes many physicochemical changes after harvest caused by the process of metabolism. The method used to inhibit the metabolic processes in tomatoes can be overcome by controlled atmosphere storage. However, this method requires a high cost. Therefore there is another method that is more practical and economical to imitate the mechanism of the controlled atmosphere is by the use of coating materials (coating). Coating material must be able to form a barrier layer of the loss of water content and can maintain fruit quality and does not pollute the environment. Chitosan is a natural alternative as a coating material that is non-toxic and safe for health. This study aimed to observe the effect of chitosan coating on quality and shelf life of fresh tomatoes at different maturity levels. The study design used was completely randomized design (CRD) factorial with two factors. The factor I was the maturity stages which consisted of 3 (three) levels : K1 = full green (0-10% red skin), K2 = light red (30-60% red skin), K3 = ripe ( 70% red skin). Factor II is storage duration which consisted of 5 (five) level : P1 = 0 day, P2 = 5 days, P3 = 10 days, P4 = 15 days, P5 = 20 days, with 2 (two) replications. The analysis conducted on tomatoes were weight loss, solusble solids concentration, total acid, and vitamin C. The results showed that the tomatoes were coated chitosan could inhibit weight loss, soluble solids concentration, total acid, and vitamin C than untreated tomatoes (control). Chitosan coating with a concentration of 1% and a long soaking for 10 minutes on the tomatoes with the maturity stages of 0-10% skin red and 30-60% skin red could maintain in good condition for 20 days of storage. But the tomatoes with the maturity stage 70% red skin only able to survive 10 days of storage.

Abstract

This study undertakes the transesterification process of used cooking oils that have undergone a process of esterification. The transesterification process carried out by reacting methanol and esterified used cooking oil using KOH as catalyst. Stirring technique used is based on hydrodynamic cavitation. This research aims to study the characteristics of biodiesel that made from transesterified used cooking oil with different concentrations of methanol. The concentration of methanol used consists of 5 (five) level are: 99.9%, 95%, 90%, 80%, and 70%. The transesterification process using hydrodynamic cavitation technique with a 99.9% concentration of methanol result in biodiesel with characteristics consistent by Indonesian National Standard (SNI). In this condition, biodiesel produced 92.93% of the yield which has characteristics of acid number 0.80 mg KOH / g, total glycerol 0.045%, alkyl ester 99.45%, iodine number 14.92 g I2/100 g,  viscosity 2,35 mm2 / s , density 0.87745 g/cm3  and pH value 4.885. Based on research, the concentration of methanol lower than 99.9% not yet can produce biodiesel from used cooking oil that have characteristics according to Indonesian National Standard (SNI).

Abstract

Kopi adalah satu dari sekian banyak minuman yang paling diminati oleh masyarakat global. Sebagian orang bahkan harus meneguk secangkir kopi sebelum memulai kegiatan hariannya. Data konsumsi kopi dunia menunjukkan sebanyak 70% peminum kopi menikmati kopi arabika, sedangkan sisanya (30%) memilih kopi robusta. Akhir-akhir ini produsen mulai memperkenalkan Kopi Wine Gayo yang mempunyai cita rasa unik. Namun derajat penyangraian yang disukai oleh konsumen untuk produk olahan ini belum diketahui. Tujuan dari penelitian ini untuk mengetahui tingkat kesukaan konsumen terhadap kopi wine gayo yang disanggrai pada derajat yang berbeda. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) satu faktor non faktorial. Faktor perlakuan, meliputi suhu 193ºC (light), 198ºC (ligh to medium), 204ºC (medium), 208ºC (medium to dark) dan 213ºC (dark) dengan 3 ulangan. Tingkat kesukaan konsumen dianalisis dengan uji hedonik menggunakan 5 skala (mulai dari tidak suka sampai dengan sangat suka). Hasil penelitian menunjukkan bahwa tingkat penyangraian berpengaruh nyata terhadap kesukaan konsumen kopi wine Gayo. Uji hedonik kopi wine menggambarkan bahwa warna yang paling disukai terdapat pada tingkat penyangraian medium dengan rata-rata 3,76 (suka), sedangkan aroma yang paling disukai terdapat pada tingkat penyangraian medium  to dark dengan rata-rata 3,75 (suka). Perlakuan terbaik didapat pada kopi wine Gayo yang disanggrai dengan derajat medium.Kopi adalah satu dari sekian banyak minuman yang paling diminati oleh masyarakat global.
