The research was aimmed at studying the effects of (1) single application AVGs,plastic wrappings, and storage temperatures, (2) interactions among AVGs andplastic wrappings, AVGs and storage temperatures, and plastic wrappings andstorage temperatures, and (3) interactions among AVGs, plastic wrappings, andstorage temperatures in extending fruit self-life and maintain qualities of?Mutiara?guava fruits. The research was arranged in a completely randomized designin 2 x 2 x 2 factorial with three replications. The first factor was AVGs (with 1,25ppm and without AVG), the second factor was plastic wrappings (without and withone layer of plastic wrapping), and the third factor was storage temperature (a coldtemperature of 21, 53 ºC and a room temprature of 26,57 ºC). The result showed that(1) the application of AVG 1,25 ppm did not significantly affect fruit self-life, fruitfirmness, fruit weight loss, ºBrix, acid contens, and sweetness of ?Mutiara?guava?fruits, (2) storage at cold temprature of 21, 53 ºC did not significantly affect fruit self-life, fruit firmness, fruit weight loss, ºBrix, acid contens, and sweetness of?Mutiara?guava? fruits, (3) the application of plastic wrapping was able to extend fruitself-life by 17 days longer than without plastic wrapping and supressed fruit weightloss of ?Mutiara?guava, but accelerated softening and not able to maintain ºBrix, andalso did not significantly affect acid contens, and sweetness of ?Mutiara?guava fruits,(4) there were no interaction effects among AVGs with plastic wrappings, AVGs withcold tempratures, and plastic wrappings with cold tempratures on self-life, fruitfirmness, fruit weight loss, ºBrix, acid contens, and sweetness of ?Mutiara?guavafruits, and (5) there were no interaction effects among AVGs, plastic wrappings, andcold temperatures on fruit self-life, fruit firmness, fruit weight loss, ºBrix, acidcontens, and sweetness of ?Mutiara? guava fruits.

â€˜Californiaâ€™ papaya is a newly released papaya cultivar in Indonesia that has a very short shelf-life. Increasing demands in both local and export markets warrant the need for a proper postharvest technology to prolong its shelf-life. This research was conducted to study the effects of fruit coatings (chitosan, KD-112, plastic wrapping), fungicide Prochloraz, and storage temperatures on its fruit shelf-life and quality. Three parallel experiments were conducted with treatments arranged in a completely randomized design of a 2 x 2 x 2 factorial design.Â The first factor was chitosan (with and without 1.25% chitosan), or KD-112 (with and without 14% KD-112), or plastic wrapping (with and without one layer plastic wrapping), the second was Prochloraz (with and without 0.67 mL/L Prochloraz), and the third was storage temperature (27-28 and 16-18 ÂºC). While Prochloraz did not affect fruit variables, cooler temperature and coatings lengthened fruit shelf-life with the best effect shown by plastic wrapping which lengthened fruit shelf-life by 13 days, without affecting fruit qualities. Significant effects of coating and cooler temperature determined their combined effects, with the best effect achieved by applying the three factors that lengthened fruit shelf-life by 11-23 days longer.

In Indonesia, pulp and paper production generally uses wood. Intensive forest explotation causes deforesting, global warming,and lessen the wood deposit and forest area. Therefore, government should seek alternative raw material such as bagasse for pulp and paper production, with naturally friendly environment pulping method, such as acetosolve method. In this research bagasse and banana fiber were used as raw material for pulp production. Then, raw material analyses was conducted for chemical content which were cellulose, hemicellulose, lignin, and ash, and pulp physical properties. The best result in pulping process was 70:30 ratio of bagasse and banana fiber with 80% acetate acid concentration which resulted 56% of cellulose, 27,4% of hemicellulose, 16,2% of lignin, 66% rendemen, 16.1 GE of brightness index, 0,83 (kPa.m/g) of break index, 2,05 Nm2/Kg Of tear index, 19 Nm/g of tensil strength, and 93% of paper opacity.

This research was aimed to find the appropriate combination of glycerol and tapioca concentration in the production of Eucheuma cottonii seaweed dreg-based biodegradable films. A two factors experiment was arranged in a Complete Randomized Design with three replications. The first factor was three levels of glycerol concentration : 0.25%; 0.5% and 0.75%. The second factor was three levels of tapioca concentration : 5%; 6% and 7%. The data of visual observation, Fourier transform infra red analysis, biodegradability and water vapor permeability were analyzed descriptively. The tensile strength, elongation and solubility of biodegradable films were analyzed using by ANOVA. The homogenity was use barlett test and the aditivity was use Tukey test. The data were continue by HSD test at 5% level of significant. The concentration of glycerol and tapioca significant effects on tensile strength and percent elongation, but not on solubility. The best characteristics of the Eucheuma cottonii seaweed dreg-based biodegradable film was produced from a combination of 0.25% of glycerol and 7% of tapioca concentration. The best biodegradabe film had characteristic of an f 53.92 MPa tensile strength, an 3.647 % elongation, 86.17% solubility, 14 day biodegradability, 6.13 g/(m2/day) water vapor permeability . The addition of glycerol and tapioca concentration in producting of Eucheuma cottonii seaweed dreg-based biodegradable film has caused the film characteristics more plastic and homogeneous.

The objective of this research was to study the effect formulation between sucrose and glucose syrup on chemical and sensory properties of soymilk candy. The research was a single factor, arranged in a Complete Randomized Design with six replications. The factor was the formulation of sucrose and glucose syrup consisted of six levels, i.e. 100:0 (F1); 90:10 (F2); 80:20 (F3); 70:30 (F4); 60:40 (F5) and 50 : 50 (F6). The data were analyzed by using ANOVA and were tested with LSD test at 5% level of significant. The results showed that the ratio of sucrose and glucose syrup significantly affected the chemical properties (moisture content, ash content and reducing sugar content) and sensory (color, odor, taste, texture, and overall acceptance) of soymilk candy. The best formulation was found on soymilk candy produced from 60% sucrose and 40% glucose syrup (F5) with the color score of 2,49 (yellow-brown), odor score of 2,34 (rather specific soymilk), taste score of 3,12 (rather sweet), texture score of 3,24 (rather soft), and the overall acceptance score at 3,05 (like). The best soymilk candy has moisture content of 8,21%, ash content of 1,38% and reducing sugar content of 8,18%.Keywords : sucrose, glucose syrup, soymilk candy.

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.
