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.

Abstrak. Informasi umur simpan tomat sangat penting untuk proses penanganan pasca panennya sehingga dapat mengurangi resiko kerugian yang dihadapi oleh para petani dan pedagang. Penelitian ini bertujuan untuk mengetahui apakah model Arrhenius dan Q10 dapat digunakan untuk menduga umur simpan tomat berdasarkan nilai total padatan terlarut (TPT). Tomat segar terbaik yang diperoleh dari pasar induk disimpan dengan 3 variasi suhu ekstrim yaitu 50˚C, 60˚C dan 70 ˚C. Selama penyimpanan tersebut dilakukan pengamatan nilai TPT setiap 1 jam sekali, sampai keadaan tomat sudah tidak layak untuk dikonsumsikan lagi. Peralatan yang digunakan adalah refraktometer digital. Analisis model Arrhenius dilakukan dengan pendekatan persamaan linier. Pendugaan umur simpan dilakukan dengan metode Q10. Hasil penelitian menunjukkan bahwa model Arrhenius perubahan TPT tomat adalah k = 7,46x1012. e -8666/T . Energi aktivasi perubahan TPT buah tomat adalah 17.158 kal/mol. Nilai Q10 diperoleh sebesar 2,18. Pendugaan umur simpan dapat dilakukan dengan pendekatan ini baik menggunakan basis suhu penyimpanan 10 maupun 30 °C. Umur simpan tomat pada suhu 30 °C adalah 4,4 dan 5 hari, sedangkan umur simpan tomat pada suhu 10 °C adalah 21 dan 23,8 hari. Perlu penelitian lanjutan untuk menduga umur simpan tomat menggunakan parameter mutu lain seperti vitamin C dan kekerasan untuk meningkatkan validitas hasil pendugaan umur simpannya.  The prediction of Tomato shelf life Based on Its Total Soluble Solid by Using Arrhenius and Q10 Model Abstract. The information about shelf life of tomato is necessary for its post harvest handling to reduce the loss facing by farmers and sellers. The study aimed to observe that the Arrhenius model and Q10 can be used to estimate the shelf life of tomatoes based on its total soluble solid (TSS). The fresh tomatoes obtained from the market were stored at three extreme temperatures i.e. 50˚C, 60 ˚C, and 70 ˚C. During the storing, the TSS was analyzed every hour, until the tomatoes quality was decreased. The TSS was observed by using refractometer. The Arrhenius model were evaluate through the TSS model in linier model. The shelf life estimation were calculated by Q10 method. Results showed that the Arrhenius model of TSS changes in tomatoes was k = k = 7.46x1012. e -8,666/T. The energy activation of TSS changes was about 17,158 kal/mol. The Q10 value was 2.18. The estimation of tomato shelf life can be run successfully by using the Arrhenius and Q10 approach, both at storage temperature basis of 10 and 30 °C. The shelf life of tomatoes at storage temperature 30 were 4.4 and 5 days, respectively, whereas at storage temperature 10 °C were 21 and 23.8 days, respectively. Therefore it is recommended for the further study to evaluate the other quality parameter changes such as vitamin C and hardness to improve the model.

<p><em>Coffee is a beverage that is widely consumed around the world. Proper packaging and storage temperature may extend shelf life of ground coffee. The study aimed to analyze the shelf life of ground Arabica coffee stored in different packaging types and temperature, conducted at smallholder coffee plantations in Garut Regency and the Integrated Laboratory of Indonesian Industrial and Beverage Crops Research Institute, Sukabumi, from June to August 2018. A completely randomized design in factorial was used with 3 factors and 2 replications. The first factor was the packaging type  which consisted of 3 types: thick alumunium  foil 65</em><em>m</em><em> (AF65), thick alumunium  foil 130</em><em>m</em><em> (AF130), and thick lamination 114</em><em>m</em><em> (L144). The second factor was the storage temperature which consisted of 3 levels: 25 <sup>o</sup>C, 35 <sup>o</sup>C, and 45 <sup>o</sup>C, while the third factor was the storage period which consisted of 5 levels: coffee unstored, and coffee stored for 2 weeks, 4 weeks, 6 weeks, and 8 weeks. The variables observed were the water and fat content, and the analysis of shelf life was carried out using the ASLT (Accelerated Shelf Life Test) method. The results showed that during storage, the water content increased, whereas the fat content decreased. Fat content is a critical variable in determining the shelf life of coffee. The coffee in AF130 packaging has longer shelf life than in AF65 and L144. To extend the shelf life of coffee packaged in AF130 and L144 is best kept at 45<sup> o</sup>C whereas coffee in AF65 packaging  is ideally at 25<sup> o</sup>C.</em></p>

Issues about environmental damage caused by the presence of plastic-based packaging materials require the development of eco-friendly packaging materials. Breadfruit starch contains amylose which has the potential to be developed into natural packaging materials, or edible films. Another function of packaging was to protect food ingredients from damage, one of which was microbiological damage. This study aimed to determine the level of breadfruit starch to produce edible films that meet the standards and to determine the ability of cinnamon extract to inhibit the activity of tested bacteria. The study was conducted using a factorial completely randomized design with 2 factors, namely the concentration of breadfruit starch and the concentration of cinnamon. The results showed that breadfruit starch can be used at a level of 6% which will produce edible film with a tensile strength of up to 6.37 MPa and a thickness of 0.23 mm. Cinnamon extract were able to inhibit the growth of Escherichia coli and Staphylococcus aureus bacteria. Both breadfruit starch and cinnamon extract have the potential to be developed as natural ingredients in the process of making edible films.

Corn (Zea mays) is one of the most cultivated poaceae in the world with high agricultural potential. It is propagated through seeds, which sometimes remain stored until the sowing period. Among the various forms of storage, some aspects related to the environment and the type of material that constitutes the packaging may compromise the viability and vigor of these seeds. Therefore, the objective of this study was to evaluate the physiological quality of corn seeds stored in different types of packaging and subjected to conditions of high temperature and relative humidity throughout storage. For this purpose, water content, germination and vigor were evaluated through the cold test. A completely randomized design in a 4 x 4 factorial scheme (packaging x evaluation times) with four replications was used. Data were subjected to analysis of variance and regression, and the means were compared by Tukey test at 5% probability, using the Sisvar 5.3 statistical software. It was concluded that, in 45 days of storage, the water content in corn seeds reached values of up to 13.62%, which resulted in a reduction in the vigor due to high respiration caused by the storage temperature.

Palembang fish crackers have a thick characteristic with a strong fishy aroma. Puffing of the thick fish cracker requires particular technique, for example the deep-frying techniques should use two different heating temperatures to obtain good quality of crackers. Another alternative method is to use heat from microwaves. One of the disadvantages of crackers that are processed with heat from the microwave is the easiness of the crackers lose its crispness. This study aimed to analyze the shelf-life of fish crackers puffed by microwave heat and deep-frying technique in some types of packaging. The research design was a factorial completely randomized design with two factors namely the type of packaging (polypropylene, nylon, metalized plastic) and type of crackers (microwaved and fried). Analysis of variance showed that all treatments have a significant effect on water content.  The indicator used for the prediction of shelf-life is water content. The water content changes during storage at room temperature for all treatments followed a first-order kinetic with the lowest k value for fish cracker packed in metalized plastic packaging with 57 days storage time (microwavable fish crackers) and 45 days (fried fish crackers)
