The most used packaging material was plastic, but can cause environmental problems because it was not easily degraded. Therefore, it was necessary to look for alternative packaging materials that are easily biodegraded including edible film. The main raw materials for edible films were alginates and plasticizers including glycerol and sunflower oil. The objective of this study was to determine the characteristics of edible film composed of alginate, glycerol and sunflower oil. The study was carried out through the manufacture of edible films composed of various alginates concentrations (2, 3, 4, 5 and 6%), 10% glycerol and 0.01% sunflower oil. The characteristics tested included thickness, tensile strength, elongation, solubility, and rate of water vapor transmission. The results showed that all treatments met the edible film standard of the Japanese Industrial Standard. The various alginate concentrations used did not significantly influence the water vapor transmission rate and tensile strength but significantly affected the elongation, solubility and thickness of the edible film.

This research aims to determine the effect of plasticizer types and concentrations on the characteristics of glucomannan bioplastics, and to determine the types and concentrations of plasticizers that can produce glucomannan bioplastics with the best characteristics. This experimental design used a completely randomized design method. Factor I is a type of plasticizer consisting of glycerol, sorbitol, propanol-2, and polyethylene glycol. The second factor is the concentration of plasticizers which consists of 4 levels, namely 0.5%: 1.5%: 2.5%: 3.5%. The experiment resulted in 16 treatment combinations and grouped into 2 groups to obtain 32 experimental units. The data were analyzed for their diversity and continued with the Duncan multiple comparison test. The results showed that the type and concentration of plasticizers had a very significant effect on tensile strength, elongation at break, modulus young, and swelling. The interaction has a very significant effect on tensile strength and expansion and has a significant effect on the elasticity of glucomannan bioplastics. Meanwhile, the type and concentration of plasticizers had no significant effect on the length of biodegradation. The best glucomannan bioplastic was obtained in the treatment of glycerol plasticizers with a concentration of 1.5 % with a tensile strength value of 6.17 MPa, elongation at break of 21.50 %, elasticity 28.72 MPa development 25.84 %, and degradation time of 8 days. Bioplastics produced in this study have meet the SNI 7188.7:2016 standards in the elongation test at break and standards ASTM 5336 in the degradation time variables. The resulting bioplastic has not met SNI on the tensile strength, modulus young, and swelling variables. Keywords : bioplastic, glucomannan, glycerol, polyethylene glycol, propanol-2, sorbitol

Rachmawati AK, Anandito RBK, Manuhara GJ. 2010. Extraction and characterization of pectin on green cincau (Premna oblongifolia) in edible film production. Biofarmasi 8: 1-10. The use of green cincau pectin was presumed to influence the result of edible film characteristics, i.e. thickness, solvability, elongation, tensile strength, and water vapour transmission (WVTR). The aims in this research were: (i) to find out the chemical characteristics of green cincau pectin on the physical (thickness and solvability) and mechanical properties (elongation and tensile strength), (ii) to determine the edible film inhibition of green cincau pectin against the water vapour transmission rate, and (iii) to find out the edible film capability in inhibiting the weight loss on green grape by wrapping and coating method. The five major steps in this research were material preparation (making green cincau powder and pectin extraction), the characterization of extraction result pectin, making edible film, edible film characterization, and edible film application. This research used a completely randomized design with twice replications in edible film making for each treatment concentration and twice replication for edible film characteristic testing in each edible film making replication. Variance analysis was used to analyze data, if there was a significant difference, it will be continued with a Duncan Multiple Range Test at a significance level of 0.05. The yield of green cincau powder and pectin were 27.5% and 15.2%, respectively. The extraction result pectin consisted of 5.09% water, 11.06% protein, 0.35% fat, 28.5% ash, 55.00% carbohydrate (by different), and 12.15% crude fiber. The increasing of pectin concentration tends to increase the thickness and tensile strength, but reduced the water vapour transmission rate. The lowest water vapour transmission rate occurred at the edible film with 30% pectin concentration. Its water vapour transmission rate was 0.317 g.mm/m2.hour. The green grape weight loss with a wrapping method was 0.0212 g/hour, and the green grape weight loss with a coating method was 0.0634 g/hour.

ABSTRACT   This research aimed to determine the effects of compost applications on ex-mining lands by using chinese cabbage as indicator. The experiments were conducted at the Faculty of Agriculture greenhouse and the soil and compost analysis were done at the Soil Chemistry and Fertility Laboratory for a duration of two months. The research employed a Completely Randomized Design method with 5 treatments repeated 3 times to get 15 experimental units. The analysis on ex-mining soil revealed that it contained only trace amounts of soil nutrients N, P, and K. The laboratory analysis on the compost sample resulted in a C/N ratio of 11.87 which suggested that the compost was mature and ready to be used. The Analysis of Variance on research data showed that compost applications did not affect plant height between treatments at each weekly observation, and similarly did not affect leaf quantity and fresh weight at harvest time.  However, the research found that the compost applications tended to improve plant height, leaf quantity, and fresh weight of plants at harvest time.  The minimal effect of compost applications between treatments suggested that the plants did not utilized the nutrients supplied by the compost in their early stages of development.  Moreover, it was also suspected that the compost applications had not been sufficient in supplying the soil nutrients needed by the plants to ensure proper growth which ultimately affected the fresh weight of the plants at harvest time.

Edible film made up of modified tapioca was used to wrap tempeh and its shelf life estimation was determined. The edible films must be capable of evenly aerating and maintaining moisture without causing condensation in order mycelium to be able to grow and produce high-quality tempeh. The experiment was carried out in completely randomized design with two main factors of storage temperature and time. An accelerated shelf life test at 17oC, 27oC, and 37oC with an Arrhenius model was used to calculate the shelf life, and water content was used as quality parameter indicator. The result showed that modified-tapioca based edible film made from fermentation of tapioca by Saccharomyces cerevisiae was characterized as having elongation of 11.40 %, tensile strength of 408.37 MPa, thickness of 0.88 mm and WVTR of 12.60 g/m2/h. Rate constant of water content decrease in edible film wrapped tempeh based on Arrhenius model was 0.3832 % day-1 and Ea was 10.296 kkal/gmol, while that of in PP-plastic wrapped tempeh was 0.3831% day-1 and Ea was 9.998 kkal/gmol. The shelf life of edible film wrapped tempeh was 9.39 days at 27oC, 5.18 days at 27oC, and 2.96 days at 37oC, while shelf life of PP-plastic wrapped tempeh was 8.64 days at 17oC, 4.85 days at 27 oC, and 2.82 days at 37oC. Therefore, it can be concluded that modified tapioca based edible film increased the shelf life of tempeh.
