Abstract

Raharjo et al., 2000. Study of Yield Losses during Drying and Milling of Paddy in Tidal Lowland of South Sumatra. J. Lahan Suboptimal 1(1):72-82.In tidal lowland of South Sumatra low quality rice called beras batik is commonly found. Beras batik is rice that is low in both quality and prices. The low quality rice grains have high fracture, the percentage of head rice is only 25%, while the percentage of yellow grain exceeds 50%, and its selling price is only Rp. 1800/kg in 2004. The main causes were poor harvest and post harvest handling, delaying harvest and post harvest due to the lack of manpower and facilities owned by farmers. The condition was worsened by the heavy rainfall during harvest time and sometimes coincided with high tide. The study was conducted on July 2011 (dry season) in tidal lowland reclamation area of Telang Rejo village, Muara Telang Sub-district, Banyuasin Regency. In this study 2 post-harvest technologies were introduced to improve harvesting techniques and post harvest handling; (1) Drying assessment of Grain Dryer Machine Fueled withhusk, and (2) Study the Different Configurations of Rice Milling Unit. Lost during drying was 2.77 for sun drying compared to 7.13% with box dryer. Field testing at RMU 1 showed that milling recovery using box dryer (63.5%) was higher than sun drying (61.6%). But, at RMU 2 milling recovery for box dryer (61.3%) was lower than sun drying (63.7%). For milling losses, box dryer (4.99%) was lower than sun drying (5.99%).

Abstract

Najib, A. 2012. Managing Degraded Peatland through Carbon Enhacement to Support Rice Security. J. Lahan Suboptimal 1(1):83-91.Indonesia often faces food problem, especially rice as the staple food for most Indonesian. To support rice security, the Government of Indonesia has made serious efforts to increase rice productivity through cultivating suboptimal land. However, utilizing it in unwise ways, especially for the degraded peatland, could release green house gases. Utilization of peatland for rice field should be done simultaneously with wise conservation to enhance carbon stock. It should be managed in a good way in order to avoid the increaseof carbon dioxide emission. The addition of carbon from this activity could be considered as a potential carbon incentive if REDD+ scheme be ratified officially. As a result, farmer would be able to receive carbon incentive as their additional income.

Bijaksana, U. 2012. Snakehead Domestication, Channa Striata Blkr, Swamp Water Optimization Efforts in South Kalimantan Province. J. Lahan Suboptimal 1(1):92-101.This research aimed at domesticating snakehead in order to fulfill the consumption without relying on catch. This research was conducted in the Wet Laboratory of the Department of Aquaculture Faculty of Fisheries Banjarbaru from September to October 2006. Snakeheads caught in "beje 'were selected according to weight and size and then kept in concrete tanks. A total of 32 pairs were placed in the experimental tanks.Feed was served as much as 4% of bodyweight/day for 4 times/day. Observations were made at the beginning and end of the experiment which included concentration of E2, egg diameter, IGS, IHS and fecundity. The results obtained were as the followings: water enhancement was associated with the development of the IGS with r2 = 0.92 which was greater than that of the decrease in water with r2=0.55.Greater reduction in water was associated with IHS with r2=0.96 which was greater then that of raising the water with  r2 only 0.74. Increase of water associated with the concentration of estradiol-17 beta with r2=0.82 was greater than that of the decrease of water which was was only 0.55.The decline and rise of water were aasociated with the diameter of each egg with the r2=0.93 and 0.96. Enhancement of water associated with agreater effect on fecundity with the r2=0.74 while decreasing water with the r2=0.36. Several indicators of snakehead reproduction obtained from the experiment were found to be similar with those naturally occured. It was concluded that the snakehead’s gonad could be grown to reach maturity level in the container as a domestication process.

Abstract

Barus, Y. 2012. The Effect of Manure Application and Planting System on the Production of Upland Rice Varieties on Dried Acid Land in Lampung. J. Lahan Suboptimal 1(1):102-106. Upland rice planted in the dry land is very potential to contribute to the national rice production since upland area is quite large and its cultivation does not require irrigation.. The research was aimed to observe the effect of planting system and the application of organic matter on the production of upland rice. The experiment was carried out in the Buyut Udik village, the Gunung Sugih Subdistrict, the Middle Lampung Regency during the first season 2008/2009. Using Split Plot Design which consisted of two factors, namely: A. Planting System (The tegel system (20 x 20 cm), The planting system legowo 2: 1, and The planting system legowo 4: 1); B. Cow manure(without manure, and with manure 4 t/ha). Inorganic fertilizers applied were Ponska 15:15:15 (200 kg/ha) and urea (200 kg/ha). The highest production of 4,52 t/ha was obtained from the treatment legowo 2:1 with manure 4 ton/ha, followed by the tiles system with manure (4,24 t/ha), and the lowest was obtained from the treatment legowo 4:1 without manure (3,55 t/ha).
