<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>

All foods have limited shelf life which vary depending on the food and storage conditions. Table eggs are perishable food and storage temperature is an important factor that affects the shelf life. In tropical countries like Nigeria, eggs are usually preserved under ambient condition due to erratic power supply, which reduces the efficiency of refrigeration system. The aim of the present study was to examine the effects of storage periods, temperature and their relationship on the pH of chicken egg internal properties (yolk, albumen and whole egg). Fresh chicken table eggs were randomly allotted to three treatments of storage temperatures; refrigerator (40C ? 2), laboratory (320c ? 4), and poultry store room (370C ? 4). Eggs were assigned to treatments in a completely randomized design, and each treatment was replicated thrice. The pH was measured daily for each storage temperature in all treatments. Storage temperature and periods had significant (P<0.05) effect on pH of measured parameters. The pH values increased with storage temperature and period of storage. The rate of pH increase was significantly (P<0.05) higher in ambient as compared to refrigerator temperature. In this study, only the refrigerator storage has pH values within the range for fresh table eggs. At storage period above three weeks, pH values increased beyond the range for fresh egg. It is validated that storage temperature and period affected egg shelf life, the rate of freshness reduced with increased temperature, thus, storage beyond three weeks of ambient temperature is not advisable in humid tropics.

Garlic (Allium sativum L.) is an agricultural commodity which is widely consumed by the community. The obstacle experienced in cultivation is that a relatively long dormancy period of about 6-7 months. The dormancy of garlic seeds occurs because the embryo has not yet been fully formed, and the growth hormone and inhibitory hormone are not balanced. The methods used to break dormancy and accelerate germination are by using corona incandescent plasma radiation and storage temperature. The research utilized factorial Completely Randomized Design (CRD), consisting of six treatments with five replications. The first factor was the corona incandescent plasma radiation carried out on the garlic seeds ‘Lumbu Kuning’ variety with time duration of 0, 15, and 30 minutes. The second factor was storage temperature comprising of room temperature and cold temperature of 7oC stored for 30 days. Viability parameters observed are germination percentage dan the length of sprouts. The data were analyzed by using ANOVA followed by the DMRT test at the 95% confidence level. The results showed that corona incandescent plasma radiation influenced the germination percentage using plasma radiation for 15- 30 minutes.

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.

The objective of this study was to evaluate dormancy and physiological quality of seeds of rice cultivars during storage in different environments. After harvesting, the seeds of three rice cultivars (Seleta, Curinga and Relâmpago) were dried in the sun, to reach moisture content at around 13%. Then, they were packed in paper and stored in four environments: 5 ± 2 ºC / 70 ± 5% RH, 12 ± 2 ºC / 70 ± 5% RH, 18 ± 2 ºC / 65 ± 5% RH and in uncontrolled condition of temperature and relative humidity (natural). Physiological quality was evaluated at the beginning and at 3, 6, 9 and 12 months of storage by germination test, electrical conductivity, accelerated aging and sand emergence. The experiment was conducted in split plots in a completely randomized design with three replications. Environmental factor was applied in the plots, cultivars in the subplots and storage period in subplots. Cultivar Seleta showed higher dormancy, which was surpassed during storage regardless of environment conservation. In general, seeds stored in natural environment showed lower physiological quality. Only the seeds of cultivar Seleta, regardless of the environment, maintained germination above the minimum required for commercialization until six months of storage.

Jelly is a candy made from components of water or fruit juice, flavor, sugar, and gelling ingredients. Apart from fruit juice, jelly candy can be made from the basic ingredients of leaf extracts. One of the leaves that can be used is Muntingia calabura L. leaves. The existing jelly candies generally do not use natural ingredients as colorings and flavors. Fruits that can be used as natural ingredients in making jelly candy are Averrhoa bilimbi L. This study aims to determine the effect of adding starfruit extract to the physical quality, shelf life, and organoleptic of Muntingia calabura L.  leaves jelly candy. This study used a Completely Randomized Design (CRD) with 1 factor, namely the concentration of Averrhoa bilimbi L extract (0%, 5%, 10%, 15%, and 20%). The results of this study indicate that the addition of Averrhoa bilimbi L extract does not significantly affect the physical quality (color) of Muntingia calabura L. leaves jelly candy. In the shelf life test, the addition of Averrhoa bilimbi L extract gave a real effect, where the best treatment was the concentration of Averrhoa bilimbi L. extract 15% and 20%. In the organoleptic test, the addition of Averrhoa bilimbi L extract did not significantly affect the level of preference (hedonic) and the level of acceptance (scoring) of the texture, but it did affect the level of panelist acceptance of the color, aroma, and taste of Muntingia calabura L.  leaves jelly candy. The best treatment of panelist acceptance level for color is at a concentration of 0% producing jelly candy with a yellowish-brown color and the best aroma and taste of jelly candy at a concentration of 20% producing jelly Averrhoa bilimbi L -flavored jelly candy with a slightly bitter sweet taste with a slightly bitter sweetness.
