PENGARUH KONSENTRASI TAPIOKA TERHADAP SIFAT FISIK BIODEGRADABLE FILM DARI BAHAN KOMPOSIT SELULOSA NANAS
This research was aimed to find the right concentration of tapioca to produce biodegradable films from composite materials of pineapple cellulose with the best physical characteristic. The research was designed using a Completely Randomized Block Design with starch concentration as the single factor. It was consisted of five levels 1%, 2%, 3%, 4% and 5% (w/v) with 5 replications. The data of visual observation and water vapor permeability were analyzed descriptively, while data of tensile strength were processed by analysis of variance. Data homogenity and additivity were tested using Barlett and Tuckey tests. The data were analyzed further by LSD test at 5% level of significance. The best result was the biodegradable film from composite material of pineapple cellulose with 4% tapioca which produced 5228, 59 Mpa for tensile strength and 9.11 g/(m2/hr) for the water vapor permeability. The addition of tapioca in producing biodegradable film from composite material of pineapple cellulose could eliminate floc or the heterogen clump-forming film materials. Keywords: Biodegradable film, tapioca, tensile strength
PRODUKSI DEKSTRIN UBIKAYU MELALUI METODE GELATINISASI SEBAGIAN MENGGUNAKAN ROTARY DRUM
This research was aimed to obtain the optimum condition and characteristics of dextrin processed from tapioca(cassava starch) by using partial gelatinization using drum dryer. This experiment was arranged in randomized compelete block design with three factors and three replications. The first factor was (V) cassava varieties, which consisted of Cassesart/UJ-5 (V1) and Thailand/UJ-3 (V2). The second factor (K) was the concentration which consisted of three levels : 30 % (K1), 35 % (K2), and 40 % (K3). The third factor (T) was the temperature of the partial gelatinization which consisted of three temperature levels that were 80o C (T1), 90oC(T2), and 100oC(T3). Characterization was conducted on dextrin processed from tapioca included chemical and physical characteristics (water absorption, and water solubility). The results showed that the varieties of cassava, concentration, and temperature have significant effect on dextrin saccharide composition, solubility in water, and swelling power. Thailand variety, 35 % concentration, and processing temperature of 90o C produced dextrin with better functional characteristics , which were 24 % of dextrin composition, 77,15 % of solubility, and 6,89 % of swelling power. Key words : Cassava, dextrin, parsial gelatinazation, rotary drum
PENYUSUNAN DRAFT STANDARD OPERATING PROCEDURE PROSES PENGOLAHAN TAHU - STUDI KASUS DI SENTRA PRODUKSI TAHU GUNUNG SULAH BANDAR LAMPUNG
A standard operating procedure (SOP) is a procedure or a sequence of steps which is standardized and must be passed to complete a particular work process (U.S. EPA., 2007). Arranging SOP draft is based on a review of Good Manufacture Practice. SOP is made for a guide line in doing process in an industry. In this research, a drafting SOP of the tofu industry was done by observating and recording every detail of the process. The research was conducted through four steps. Firstly, field observation to observe the process, this includes sanitation, tools specification, and description about step of processing the tofu. The Second step was determining the critical point and optimating the condition. The next step was arranging the SOP draft. The last step was testing of the SOP draft. Then the data were compared and discussed descriptively. The result showed that the implementation of SOP draft in Tofu Production gave tofu with better characteristic in flavor, aroma, color, compactness, appearance and texture which were prefered than the products made without using reference of the SOP draft. Key words: good manufacturing process standard operating procedure (SOP), tof

This research was conducted to find out the effect of gelatin concentration on the sensory characteristic of goat milk jelly candy. The research was designed using a Completely Randomized Block Design with gelatin concentration as a single factor consisting of five levels, namely 5%, 10%, 15%, 20%, and 25%. The research was repeated 5 times. Data were analyzed with Analysis of Varians to find out the treatment effects, then continued tested using Least Significant Difference (LSD) test to find out the best treatment which was determined by the highest score of flavor, elasticity, color, and overall acceptance. Chemical composition analysis was conducted on the best treatment product. The result showed that gelatin concentration had significant effect on flavor and highly significant effect on elasticity, color, and overall acceptance of the goat milk jelly candy. The best treatment was gelatin addition at a concentration of 10%. The candy had a flavor score of 3.35 (rather typical of goat milk), an elasticity score of 3.55 (elastic), and hedonic score for color of 3.66 (like) and an overall acceptance of 3.73 (like).

PENGARUH JENIS KEDELAI DAN JUMLAH AIR TERHADAP SIFAT FISIK, ORGANOLEPTIK DAN KIMIA SUSU KEDELAI
Soybean milk, a highly nutritious drink especially in protein content, is made from soybean. Some of the benefits of soybean milk are relatively low price , suitable to be consumed by people with lactose intolerant and for people with diabetes mellitus, favored by children, and easy to manufacture. Soybean milk quality is determined by the type of soybeans and the amount of water used to dilute. The research objective was to determine the influence of the type of soybeans (Edamame var. Ryoko, Import, and Local var. Willis) and the amount of water (8, 10, 12 parts) on physical, sensory, and chemical characteristic of soybean milk. The study was conducted in a complete randomized block design with three replicatations, and replication used as a group. The data were analyzed using analysis of variance to determine various error estimators and further tested using Duncan's test find whether there is a difference between treatments. The result showed that viscosity of soybean milk did not influence by the type of soybean but it is influenced by the amount of water. The interaction between the type of soybeans and the amount of water did not affect the organoleptic properties (color, aroma, and taste) of soybean milk. Keywords: milk, soybean, sensory properties, water dilution
PENGARUH KONSENTRASI CaCl2 DAN LAMA PERENDAMAN TERHADAP SIFAT ORGANOLEPTIK KERIPIK PISANG MULI (Musa paradisiaca L.) DENGAN PENGGORENGAN VAKUM (VACUUM FRYING)
The ripe muli banana is very sensitive to high temperatures, therefore this type banana cannot be fried at normal atmosphere pressur. Therefore , a frying process at low temperature and low pressureis needed. The objective of this research was to determine the best CaCl2 concentration, soaking time, and the interaction between them in producing the best muli banana cracker using vacuum frying. The factorial experiment was arranged in a complete randomized block design with three replications. The first factor was the CaCl2 (K) concentration and the second factor was soaking time (T). The CaCl2 concentration consisted of three levels: 1% (K1), 2% (K2), and 3% (K3). The soaking times were 10 minutes (T1), 20 minutes (T2), and 30 minutes (T3). Weight of each sample processed was 2 kg. The sensory evaluation data homogeneity and additivity were tested using Bartlet and Tuckey tests. Then the data were analyzed using ANOVA, and further analyzed using honest significant difference with significant level of 5%. The best organoleptic properties of vacuum fried muli banana cracker was found on the treatment of 1% CaCl2 soaked for10 minutes (K1L1) with characteristics of typical banana aroma, yellow brownish color, sweet and a little bit sour taste, no after taste, and crunchy. The overall acceptance was favorable. Keywords: CaCl2, cracker, crunchiness, muli banana, vacuum fryin
