Abstract

Indonesia is rich in tropical fruit. However, many tropical fruits face a post-harvesting problem related to the short shelf-life of fruits due to the high respiration, transpiration, and decaying by fungi. To solve this problem, it is necessary to prolong the shelf-life of tropical fruit by applying bioactive food packaging which can prevent fruit from decaying and rotting. Among the prospective bioactive food packaging is biodegradable film made of cellulose nanofibril (CNF). CNF is new nanomaterial containing thin fiber from cellulose. This material forms transparent gel, thus it is easily to be modified into biodegradable film which is homogenous, safe, environmentally friendly, and renewable. CNF nanomaterial can be derived from lingo-cellulosic material through the process of lingo-cellullose degradation followed by homogenization using fluidization process. This process results in CNF transparent gel which can be readily modified as biodegradable film. This biodegradable film is then can be applied to the tropical fruits to prolong their shelf-life. CNF bioactive food packaging has high mechanical strength and high protection against oxidation process. This paper comprehensively reviews the advanced technology of upgrading lingo-cellulosic biomass waste into CNF biodegradable film and the technic of applying it as bioactive fruit packaging.

Abstract

Alginate has been widely used in industrial field because of its natural properties as gelling agent. Brownseaweed, especially Sargassum and Turbinaria as the alginate sources are widely grown in Indonesia; butunfortunately there has yet to be any alginate industry in Indonesia. Alginate content in Sargassum isconsidered quite large, about 35%, whereas alginate content in Turbinaria is only around 20-25%. In thisresearch, sodium alginate was isolated from dried brown seaweed (Sargassum sp.) which first passedthrough the acid treatment using 0,5%-b/v HCl and alkaline treatment using 0,5%-b/v NaOH. Extraction wasdone in batch, using 2%-b/v Na2CO3 solvent. The chosen post-treatment method was through the Ca-alginatepath with experimental design Reponse Surface Methods-Central Composite Design with 5 center point. Thevaried variable was the concentration of CaCl2 (0,11 – 2,09 M) and the ratio of CaCl2 solution/alginateextract (0,48 – 4,02 g/g). The result showed that higher concentration of CaCl2 increased the yield, viscosity,and ash content. As the ratio of CaCl2/alginate extract got higher, the viscosity had the tendency to decreaseand the ash content increased. Yield of the obtained sodium alginate powder was 6,95 -30,7%; 1,48 – 11,85cP viscosity; ash content about 18,46 – 52,65%; and water content around 6,14 – 8,32%. The optimumcondition was obtained at CaCl2 concentration of 1,02 M and the ratio of CaCl2/alginate extract about 2,01g/g with 27,72% yield, 11,38 cP viscosity, 19,56% ash content, and 6,14-8,32% water content of sodiumalginate.

Abstract

Small electroplating industry is a small industry that is widely available in the city of Semarang. The mainprocesses in the electroplating industry are located in the coating process. This process occurs in theelectroplating bath. The quality of the metal coating is highly dependent on the quality of the chemicalsolution contained in the electroplating bath. If the chemical solution has good quality, such as the solutionwas clear, there are no impurities, the quality of the coating is also good. If the quality of the chemicalsolution is not good, then the results of the coating are also inferior such as there are bubbles in the layer, orthere is dirt on the die so that the coating process must be repeated. This will add to the cost of productionand a coating time so that increases operational costs. To solve this problem we need a system that canproduce a chemical solution that has good quality, clear, and there are no impurities. This system is calledthe filter electroplating. Results of electroplating filter application showed to increase the quantity andquality of production. The production capacity increased by 30% per day. The production turnover up 35%and profits increased by 45%. The chemical solution becomes clear and does not contain impurities so thatthe coating results becomes good.
