Abstract

Sambal or sauce is a supplementary ingredient that dominates the market. But, many products do not include an expiration period. Sambal sauce generally can not be consumed once, so it needs storage to be more durable. The main damage is characterized by changes in physical, chemical, biological, and organoleptic characteristics. Various studies on the shelf life of chili sauce have been carried out, so the purpose of this study is to identify, analyze, and compare literature sources in the form of research results that show the effect of temperature differences on the chemical, microbiological and organoleptic properties of various chili sauces, so it is expected to be useful for serve as a reference for efforts to control damage to sauces or chili sauce by making the best storage. There are 5 groups of chili sauce, they are chili sauce, tomato sauce, onion chili sauce, fruit sauce, and andaliman sambal. The chili sauce is stored in three different temperatures (low, room and high temperatures) with the Accelerated Shelf Life Test (ASLT) method and Arrhenius model. Based on the results of the study, there is a low temperature storage of chili sauce last longer than room temperature and high storage that is 34-170 days. Whereas at room temperature and high temperature storage each lasted for 23-98 days and 21-54 days.

Abstract

African catfish flour can be used for making pempek from premix flour. The objective was to study the effect of the catfish flour and compare tapioca and wheat flour to the texture and hedonic profiles of pempek lenjer from premix flour. The methods consisted of making catfish flour and pempek from premix flour. The treatments were catfish flours of 15%, 20%, and 25% and a comparison of tapioca and wheat flours of 1:1, 2:1, and 3:1, respectively. Analysis on catfish flour was yield and proximate characteristics, as well as analysis on pempek lenjer, were texture profiles of hardness, springiness, and stickiness, and hedonic profiles of color, aroma, taste, and springiness texture. A complete two-factor random design and Duncan’s post hoc analysis were used in the research. The results showed that catfish flour has a yield of 20%, moisture of 6,6%, ash of 1,54%, protein of 50,94%, fat of 16,75%, and carbohydrate of 24,17%. In addition, the more the catfish flour and the less the tapioca used led to the lower the hardness and the higher the springiness of pempek lenjer. However, it did not significantly affect the stickiness. The hedonic analysis showed that this pempek has a high preference value on all parameters. The texture profiles and hedonic test produced a combination of catfish flour of 20% and a comparison of tapioca and wheat flour of 2:1 as the chosen product in this research.

Abstract

The advancement of active packaging technology has contributed to the need for customer assurance of the quality and protection of fresh foods and agricultural products. An example of active packaging to maintain food quality and improve product protection is the use of antimicrobial pads. Antimicrobial pads are a type of active packaging that releases active agents into the headspace food packaging in order to prevent, inhibit or destroy the growth of microorganisms.. Antimicrobial pads are very easy to apply to food products by placing them on the bottom of the product or inserting them into the packaging material. This literature study discusses the characterization of cellulose as a major component in the manufacture of pads, techniques for the incorporation of antimicrobial compounds into pads, and suitable applications for the inhibition of microorganisms in food products. Apart from that, this literature study also discusses the advantages and disadvantages of antimicrobial pads as active packs.

Abstract

Sidomulyo Village is one of the coffee-producing locations in Silo District, Jember Regency. The coffee processing waste is no handling. The coffee processing wastewater could potentially lead to a decrease in environmental quality. Phytoremediation is an alternative technology that can be applied because of the availability of a waste storage pond in Sidomulyo, which can to become a pool for phytoremediation. Besides, phytoremediation is a simple technology that can reduce the concentration in coffee processing liquid waste. The purpose of this study was to compare phytoremediation alternatives using the aeration, circulation, and constructed wetland (CW) system, which is the most feasible to be applied to coffee processing wastewater treatment in Sidomulyo Village based on technology and cost aspects. The stages of this research were direct surveys of respondents, comparing the efficiency of phytoremediation performance with aeration, circulation and constructed wetland (CW) systems, analysis of technical feasibility, and costs. The research results show that phytoremediation with the CW system is more than feasible than aeration and circulation systems based on technological and cost aspects. Phytoremediation application using the CW system based on the technology or technical aspects is more than feasible because it easy application and has a shorter residence time (continuity). The value of the reduction efficiency of TSS, BOD, and COD parameters in coffee wastewater treatment using phytoremediation with the CW system is sequentially 29.80; 63.75; and 63.70%. Inventory cost of constructing CW for processing coffee wastewater of Rp. 64,050,000 with a storage capacity of 82.5 m3.
