Abstract

The purpose of this study was to determine the tendency of tamarind (Tamarindus indica L.) leaf extract damage at different temperatures during storage and to determine the storage temperature that can sustain the antioxidant damage of tamarind leaf extract (Tamarindus indica L.) during storage time. Tamarind leaf extract was stored for 4 (four) weeks at 3 (three) different temperature conditions (room temperature / 27 ± 2?C; cold temperature / 5 ± 2?C; and freezing temperature / -10 ± 2?C) and analyzed for total phenolic, antioxidant capacity. and weekly levels of vitamin C. The data obtained were tabulated and analyzed descriptively. The results of this study indicate that at room temperature (27 ± 2)?C, cold temperature (5 ± 2)?C, and freezing temperature (-10 ± 2)?C, total phenolic, vitamin C levels, and antioxidant capacity have a tendency to decrease during storage. four weeks. The highest decrease in total phenolic occurred at room temperature (27 ± 2)?C, the highest decrease in vitamin C levels and antioxidant capacity occurred at freezing temperatures (-10 ± 2)?C. Storage with cold temperatures (5 ± 2)?C can retain the antioxidant content of tamarind leaf extract for four weeks and is the best storage condition. Keywords : Storage temperature, tamarind leaves extract, totalphenolicc, antioxidant, vitamin C

Abstract

This research were aimed to 1) find out amount and kind of red onion (Allium Ascalonicum L.) distribution lines from farmers in Kintamani District Bangli regency area until Denpasar city, 2) to identify what factors are identified in the red onion (Allium Ascalonicum L.) handler in Kintamani sub-district of Bangli Regency, and 3) know the impact of post-harvest handling when the distribution of red onion (Allium Ascalonicum L.) loss from farmers in Bangli District Kintamani District. The research method used is survey method, with CSAM (Commodity System Assessment Method) application and using survey instrument in the form of questionnaires distributed to farmers, pegepul, merchants and red onion retailers in Kintamani sub-district to Denpasar. The were four distributions lines of red onion (Allium Ascalonicum L.) handler from farmer at Kintamani District, namely line Line I (Farmer?retailer), Line II (Farme?collector?retailer), Line III (Farme?collector?retailer), and lines IV (Farme?collector?traders?retailer). Identification Postharvest handling factors at the farm level include cleaning and sorting. At the collecting level include transportation and storage, at the merchant level includes cleaning, sorting and transport, and at the retailer level includes cleaning, sorting and display. Impact on Postharvest loss on the farmers level is at the sorting reaches 6% (significant). At the sorter level the collector reaches 5%, at the sorter seller level reaches 5%, and at the sorter retailer level reaches 6% (significant). Keywords : CSAM application, onion, aplication

Abstract

The purpose of this research is 1). to determine the number of distribution paths celery (Apiumgraveolens L.), the type of distribution lines 2). postharvest handling of celery, and the impact of postharvest losses and the value of the damage of farmers to retailers Baturiti district. The method used in this research is survey method with the application of the Commodity Systems Assessment Method in the form of questionnaires distributed to farmers, collectors, wholesalers, suppliers and retailers of celery. There are four lines of celery distribution, there are, the first (I) is farmers ? retailers, the second (II) is farmers ? collectors ? retailers, the third (III ) is farmers ? collectors ? wholesalers ? retailers, and the last (IV) is farmers ? collectors ? wholesalers ? suppliers ? retailers. Post-harvest handling at the farm level include harvesting, sorting and cleaning, packaging and transportation. Post-harvest handling at the level of collectors, and wholesalers include weighing, sorting, and transporting, postharvest handling at the retail level covering inspection, packaging, and display, postharvest handling at the level of suppliers includes weighing, sorting, packaging and transportation, postharvest handling level includes supermarkets weighing, inspection, and display. Impact on celery postharvest losses at the farm level, namely the harvest reached 14,53% (significant), at the level of the collectors in the transport process is reached 0,44% (insignificant), at the level of big traders when transporting reached 0% (insignificant), at the retails level in sorting reached 0% (insignificant), at the sorting supplier level reached 1,55% (significant).

Abstract

This study aims to determine the effect of various preliminary treatments on the quality characteristics of ubi gadung’s starch (Dioscorea hispida dennst) and to find out the preliminary treatment that can produce ubi gadung starch with the best quality. This study used a randomized block design (RBD) with four preliminary treatments including water immersion, 10% NaCl, 15% NaCl and 0.3% Na Metabisulfite, which were repeated twice. The parameters tested were water content, starch content, yield and sensory including plural color comparisons. Data were analyzed using ANOVA and continued with Duncan's (? = 0.5%). The results showed that each preliminary treatment had no significant effect on each parameter observed, and the best results were in the 15% NaCl immersion treatment. The 15% NaCl immersion method produces starch with a moisture content of 8.50%, starch content of 14.35%, yield of 12.52%, and multiple color comparison test at score 5 with the most frequency (closest to R = 4) Keywords : wild root yam, immersion, starch

Abstract

The aim of this research is to know the number of distribution channel of the flower from farmers in Petang District to the retailer, to know the impact of postharvest loss on the flower of farmers from Petang District to retailers.The research used commodity system assessment method method in the form of questionnaires distributed to farmers, collectors, and flower retailers. Impact of handling during farmer level is at clearance and sorting significance reach 15,33%.At the level of collectors is on cleaning and sorting significantly reaches 5.17%. Meanwhile, at the retailer level the impact of sorting on the loss of flower interest is significant ie 12.5%. Physical damage that occurred in the form of flower broken flower at sortation. Physical damage occurs due to collisions, friction, and piles during the distribution process at the retailer level. Keywords : CSAM, distribution channels, flower.
