Jurnal Lahan Suboptimal: Journal of Suboptimal Lands (JLSO) (p-ISSN 2252-6188; e-ISSN 2302-3015) publishes original research papers, literature reviews, and short communications that cover on topics relevant to suboptimal lands: freshwater swamps, tidal lowlands, peatlands, dry and dry acid lands, shaded ecosystem, ex-mined lands, saline and marine coastal wetland ecosystems. The Journal serves as a multi-disciplinary forum covering key issues in Suboptimal Lands science and technology, management, policy and ecological economics. The journal is published by Pusat Unggulan Riset Pengembangan Lahan Suboptimal (PUR-PLSO), Universitas Sriwijaya. The journal was first published on April of 2012 with twice per year in frequency on April and October.

Abstract

Halimi et al. 2012. In-situ Evaluation of Growth Rate and Yield Components of  Several Non-tidal Swamp Rice Accessions in South Sumatera. JLSO 1(2):107-115Rapid increase of agricultural land conversion has led to the intensified utilization of  non-tidal swamp. The objective of this research was to identify growth rate and yield components of several rice accessions of non-tidal lowland swamp of South Sumatera. This research incorporated the cultivation of nine rice accessions  in  non-tidal swamp area. Research plots were prepared  by local farmers to include  27 plots of 280 cm x 80 cm following the Complete  Randomized Block Design.  Research indicated that rice accessions might be classified into 3 groups of Low Growth Rate (LGRA), Intermediate Growth Rate (IGRA), and High Growth Rate (HGRA) accessions.  Each group has different growth rate according to the field water level during flooding season of < 5 cm, 5 to 6 cm, and >6 cm  per week, respectively. The LGRA group consisted of  Petek (A5) and Senia (A6), the IGRA group consisted of Bone (A1), Pelita Rampak (A2), and Sawo Rimbo (A7) and the HGRA group consisted of Kuning (A3), Siam (A4), Sawah Beling (A8) and Putih Olak (A9). Some yield components tended to decrease as the growth rate increased, and some varied depending on the accessions. For effective and efficient cultivation, farmers should apparently consider growth rate and yield potential to decide which rice accessions to grow.

Abstract

Sasanti & Yulisman. 2012. Growth and Persistence of Snakehead Fry Treated with Feed from Snail Flour. JLSO 1(2):158-162. An experiment was conducted to observe the effects of feed from snail flour on the growth and survival rate of snakehead fish (Channa striata)fry. There were three treatments, each had three replications, stocked with 20 fry. The three diets treatments were artificial feed A with 35% snail flour, artificial feed B with 40% snail flour and artificial feed C with 45% snail flour. Snail flour was made from Pomacea sp. Survival and growth rate of fry were not significantly different among the three different treatments.
