Color and freshness of mangosteen are important characters as benchmarks for consumers in the selection and purchase of mangosteen in the market. Color, freshness and shelf life of mangosteen are affected by the stage of maturity at harvest and the correct storage temperature. Information about the correct maturity stage for harvesting and storage temperature of mangosteen are needed by the mangosteen farmers, local merchant, and exporters as an effort to maintain the quality of fresh product. The objective of this research was to study the effect of several maturity stage at harvest and storage temperature to mangosteen color changes and shelf life during storage. The research used Completely Randomized Design of two factors. The first factor was the fruit maturity stage at harvest consisting of: Maturity Stage 1, 2, 3 and 4. The second factor was storage temperature of 15 oC and room temperature. The result of harvesting mangosteen at Maturity Stage 1 could maintain skin color longer than at Maturity Stage 2, 3, and 4. Mangosteens that were harvested at Maturity Stage 1 and 2, combined with storage temperature of 15 oC could maintain fruit quality up to 30 days after harvest and could be used for export market. While harvesting at Maturity Stage 3 could maintain fruit quality up to 25 days after harvest and Maturity Stage 4 up to 20 days after harvest. Harvesting at Maturity Stage 4 followed by 15 oC storage temperature and all Maturity stages combined with room temperature storage could be used for local market.Keyword: fruit color; horticultural commodities; queen of tropical fruits; shelf life

Rice (Oryza sativa L.) is first staple crop of Nepal. The national average yield of rice is less than its potential yield, for which poor agronomic management has been reported as the critical factor. Among various agro-management practices seedling age, seeding density and nitrogen rates significantly affect the growth and yield of rice. The lower seeding density produces the taller plant, more effective tiller, lower sterility and higher grain yield. On the other hand, seedling of older age from higher seeding density gives the lowest yield. Transplanting younger seedling with low seeding density and application of recommended dose of nitrogen gives a higher yield. This article summarizes various effects of seedling age, seeding density and nitrogen rates on plant height, number of effective tillers, number of filled grains, thousand grain weight and grain yield of rice. This information may be useful for maize growers and researchers.

Cellulose as an abundant source of glucose in Indonesia requires acceleration of decomposition utilizing cellulolytic bacteria. Cellulolytic bacteria can be obtained from the isolation of mangrove organic matter, such as sediments. Muntok Sub-district is one of the regions with the most tin mining in West Bangka Regency also has mangroves in the coastal area. Exploration of cellulolytic bacteria in mangroves with different environmental characteristics encourages researchers to find new bacterial strains that produce cellulase enzymes with new properties. Thirteen isolates were successfully isolated from three locations. Tembelok mangrove sediments produced Seven bacterial isolates, Peltim Mangrove samples produced three isolates and from Sukal Mangrove three isolates were obtained. Seven isolates showed clear zones in the Lugol test and three isolates including were gram-positive bacteria. Molecular test with 16S rRNA analysis showed TBL1 isolate has 85% similar identity of Vibrio parahaemolyticus strain HY3 and TBL2 isolate has 98% similar identity of Bacillus amyloliquefaciens strain HS8.

Muntok Sub-district is one of the regions with the most tin mining in West Bangka Regency also has mangroves in the coastal area. Exploration of cellulolytic bacteria in mangroves with different environmental characteristics encourages researchers to find new bacterial strains that produce cellulase enzymes with new properties. Thirteen isolates were successfully isolated from three locations. Tembelok mangrove sediments produced Seven bacterial isolates, Peltim Mangrove samples produced three isolates and from Sukal Mangrove three isolates were obtained. Seven isolates showed clear zones in the Lugol test and three isolates including were gram-positive bacteria. Molecular test with 16S rRNA analysis showed TBL1 isolate has 85% similar identity of Vibrio parahaemolyticus strain HY3 and TBL2 isolate has 98% similar identity of Bacillus amyloliquefaciens strain HS8. Bacillus amyloliquefaciens potential to further study as cellulose degrading bacteria for feed ingredients.","PeriodicalId":33480,"journal":{"name":"International Journal of Applied Biology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42167913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
