Abstract

The aim of the research was to determine the shelf life of white oyster mushroom flour in polyethylene plastic packaging with the Arrhenius method. The study was arranged descriptively with two replications. White oyster mushroom flour was stored at three storage temperature conditions, i.e. 30oC, 40oC and 50o C in polyethylene plastic packaging with a thickness of 0.03 mm and stored for one month (28 days). Observations were made on water content, levels of free fatty acids, protein content, flavour and color of white oyster mushroom flour every once a week i.e. on days 0, 7, 14, 21 and 28. The data obtained were used to determine the shelf life of white oyster mushroom flour using acceleration (accelerated storage) method with Arrhenius equation model using Microsoft Excel software. The results showed that the shelf life of white oyster mushroom flour in polyethylene plastic packaging thickness of 0.03 mm using the Arrhenius method was set at a temperature of 30o C based on the parameters of the zero reaction protein content, which was 130.67 days (4.3 months). White oyster mushroom flour in polyethylene plastic packaging thickness of 0.03 mm during storage temperature of 30o C, 40o C, and 50o C tends to decrease protein content, color and aroma, but experience an increase in free fatty acid levels. White oyster mushroom flour in polyethylene plastic packaging at 30o C tends to increase in water content during storage, and decreased water content at 40o C and 50o C.

Abstract

Food, especially rice, is a basic human ingredient whose needs increase following thepopulation growth. On the other hand the availability of rice has decreased following theland conversion rate. To overcome land conversion and to increase national rice production,the government made policy of paddy expansion / printing. In 2016 this activity isimplemented in 27 provinces and has been printed new fields of 129,096 ha. One of theprovinces that get the rice field printing program is West Kalimantan Province. From theresults of the evaluation, the location of the new paddy fields is in accordance with theobjectives of the program, namely: rice fields have been formed, farmers who work aroundthe location of land and water sources for cultivation is also available. From the paddy fieldexperience of 2016, the improvements required for next year's paddy fields include: (i) preferably planning (SI & D) in advance a year is made than the implementation and (ii) additionalpaddy rice costs, as the cost of expensive tool mobilization and social costs and (iii) a bindingrule in the form of sanctions for the farmer who converted the new fields. As for improvingthe required crop index: water management; subsidizing inputs (seeds, fertilizers, lime, farming tools and cultivation training.

Abstract

The former quartz sand excavation land is a potential land for agricultural land. This land generally contains sufficiently high sand and very low fertility. The use of new superior varieties adaptive and tolerant can increase production. This study was carried out in the experimental field owned by BPTP in Gantong Village, East Belitung Regency, Bangka Belitung Islands Province. The design used was a randomized block design using three types of superior varieties, namely Inpari 22, Inpara 3, and Inpara 5. Each replication was repeated 3 times. Planting uses the jajar legowo system 4:1 (25 x 15) x 40 cm with 2-3 seedlings/planting holes. The fertilizer used is NPK 15:15:15 300 kg/ha and Urea 100 kg/ha. Urea fertilizer is given 3 (three) times each when plants are 7 days after planting (HST) as much as 25%, 25 HST as much as 50%, and 45 HST as much as 25% dose. Lime and organic fertilizer with a dose of 1 ton/ha each. Parameters observed included plant height, number of tillers, and production. The results of the study indicate that the growth of Inpara 5 has better than other varieties. The highest plant height and number of tillers are owned by Inpara 5, but not significantly different than Inpara 3 and Inpari 22. From the aspect of production Inpara 5 (2.23 t/ha) is significantly different from the varieties Inpara 3 (1.51 t/ha) and not significantly different from Inpari 22 (2.21 t/ha).
