Abstract

Garlic has a bitter taste, which makes people reluctant to eat one whole garlic clove. The salt soaking technique used to reduce the bitter taste of the garlic, and the garlic processed into wet candied garlic, so it became more edible than not process. The process of candied garlic could preserve the durability level, which allows it to be stored longer at low temperatures. The research materials used were salt and sugar. The purpose of the research was to know the effect of salt concentration on reducing bitterness and the right concentration to reduce the bitter taste of garlic. This research used the RAK method, and DMRT (Duncan’s Multiple Range Test), and the samples of salt were 3%; 3.5%; 4%; 4.5%. The test included chemical tests (water content and total microbes) and organoleptic tests (taste, aroma, and texture). The water content of the product showed the result, which was not significantly different, and the total microbes test showed no microorganism was found or grew on the product. The organoleptic test of taste was obtained on 3.5% salt, with an average of 2.75% (likes), while the aroma and texture did not show a significant difference in the result. The aroma and texture data obtained on 2.90 (likes) and 2.40 (likes) with 3.5% salt. Keywords: Candied; Garlic; Salt; Soaking; Sugar.

Abstract

Petunia (P. inflata) is one of the most commonly cultivated ornamental plants because it has different flower sizes, and is easier to grow at various media and temperatures. Indonesia is one of the exporting Countries for Petunia hybrid seed. As one of the countries that provide hybrid seeds, the problem that often faced when making pollination is the availability of pollen with high viability because pollen viability can decrease/disappear within a specified period. The purpose of this research is to determine the effect of temperature and storage period on the viability of Petunia pollen and determine the best temperature and storage period to keep Petunia pollen. The design of this study uses a Randomized Block Design with Split Plot Design. The main plot consists of a storage period for seven days, 14 days, 21 days, and 28 days. The sup plots include storage temperature treatment at room temperature, 5˚C, -5˚C, and -15˚C, there repeated for three times. Data analysis using Analysis of Variant (ANOVA) and further testing using 5% Duncan Multiple Range Test (DMRT). The observed parameter consisted of the germination energy of pollen, pollen tube length, and colored pollen. The results showed that the lower temperatures could keep pollen viability for longer. The longer pollen stored, the viability will decrease further -15°C storage temperature can maintain pollen viability high up to 28 days of storage.

Abstract

Flavonoid compound is an important compound of tea products. However, the flavonoid level content in black tea is lowest than other teas. This is due to the processing of black tea which has an enzymatic oxidation stage and  the tea age leaves when picking. Young tea leaves contain higher total flavonoids than old tea leaves. With an average level of total flavonoids, the young tea leaves is 27.76% qe w / w, while for the old tea leaves 18.61% qe w / w. However, the enzymatic oxidation time treatment did not affect the total flavonoids because the process only affected the quality of black tea steeping, on it’s colour, aroma, and taste. Keywords: age of tea leaves, black tea, enzymatic oxidation, total flavonoids
