Abstract

Kartikawati et al, 2017. Utilization of Rainfed Rice Areas for High Yielding Rice Cultivation on Climate Change. JLSO 6(2):142-149.Many efforts have been conducted by Indonesian government for national food supply and food security through rice cultivation on sub optimal lands in accelerating food sustainability particularly rice, maize and soybean. The rainfed area is an important sub optimal land which should be developed due to 26,5% of Indonesia rice production produced from cultivation system in those area. However, the cultivation in rainfed areas have challenges such as changing of rainfall pattern due to climate change. Therefore, to obtain the information of productivity from high yield rice varieties and methane emission in rainfed area, a study has been conducted by applying innovation of environmental friendly technology such as fertilizer use based on integrated cropping calendar. The study was carried out at Research Station of Indonesian Agriculture Environment Research Institute in Jakenan, which is one of rainfed area in Pati District, Central Java Province. The study was conducted on first growing season (GS 1) or rainy season by applying direct seeded system using rice seeder. Four rice varieties were used for this study, namely Ciherang, Dendang, Inpari 31 and Inpari 24. The study showed that productivity of four rice varieties were 5.92; 7.10; 5.06 and 7.41 t/ha, respectively. Methane emission was significant different among the varieties as 232; 319; 300 and 405 kg/ha/season, respectively.

Abstract

Suminarti et al, 2018. Application of Organic Matter in Sorghum Plants (Sorghum bicolor L.Moench) var. KD4 on Dry Lands for Soil Nutrient Supply Improvement. JLSO 7(2):144-156. The low content of soil organic matter and soil fertility are characteristics of dry land. Therefore, so the land can be utilized for agricultural farming, a material that is capable of acting as a soil improvement is needed, namely organic matter. The study aimed to examine the effect of the source and dosage of organic matter on the supply of nutrients, growth and yield of sorghum plants was carried out in July 2016 in the experimental garden of  Brawijaya University. A split plot design was used in this study. The sources of organic material (sugar can waste, organic waste compost and cow dung) were set as the main plot, whereas doses of organic matter (125, 100 and 75) % of recommended dosage as subplots. The study was repeated 3 times. Soil analysis was carried out 3 times, namely: (1) before planting (BO, N content, P, K soil, soil pH and soil texture), (2) after application of organic material (BO and N, P, K soil content) and (3) after harvest (BO and N, P, K soil content). The agronomic observations were carried out destructively on generative phase at 80 days after planting (DAP) including the components of growth (root dry weight, leaf area, and total dry weight of the plant) and harvest at age of 90 DAP. F test at 5% level was used to test the effect of treatment, while the difference between treatments was based on LSD level of 5%. The results showed that there was a significant interaction between the source and dosage of organic matter on the variable leaf area and total dry weight. The highest yield was obtained in sugar can waste  at various doses. Higher yields of seeds per hectare were also found in sugar can waste  which is equal to 1.76 tons ha-1. The sugar can waste application  is able to provide N, P and K soil elements of 18.3%, 85.68% and 8.42% respectively compared to organic waste compost and cow dung.

Abstract

Hasbi. 2012. The Improvement of Rice Postharvest Technology in Sub-Optimal Land. PLSO 1(2):186-196. Rice is the most exerted food crop commodity in Indonesia. Rice production has continuously been increased in order to support food security policy. Improvement of cultivation technology has been proved to increase rice production significantly.  Increase in rice production should be followed by the improvement of rice quality based on the standard and consumer preference. The improvement in  quality may also be enhanced by proper postharvest technology. Improvement of rice quality will result in more added value on rice. Therefore, proper technology which includes  production, harvest, and post harvest should be done in an integrated manner in order to increase  rice quality and at the same time decrease weight loss. Rice postharvest technology consists of harvesting, threshing, transportation, drying, cleaning and storage. These postharvest activities are often followed by  rice milling. However, farmers awareness and knowledge regarding  proper postharvest technology are lacking and its application is considered low. Improvement of postharvest handling technology should be prioritized to include three stages, which are  harvesting, threshing and drying due to high loss occured in these stages. The improvement  of harvest and postharvest technologies should incorporate human resource ability and  information dissemination based on the principles of Good Handling Practices (GHP).
