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

Mining activities provide economic benefits and also cause environmental and land ecosystems damages. The damage caused by such top soil layer loss, drought, soil compaction, low water holding capacity, poor nutrient (macro nutrients), accumulation of toxic elements and highly acidic soil reaction. Mined land reclamation of coal with bio-fertilizer technology as arbuscular mycorrhizal fungi (AMF) indigenous is one of the technologies for revegetation of land with environmentally friendly systems. This study aims to get a AMF biofertilizers indigenous effective and adaptive for rubber seedlings planted in coal-mined soil. Research used a completely randomized design with one factor that the FMA indigenous derived from in coal-mined soil; A (without inoculation; B (inoculation of Glomus sp-5), C (inoculation of Glomus sp-6), D (inoculation of Glomus sp-7), E (inoculation of Glomus sp-12), F (inoculation of Glomus sp-15); G (inoculation Acaulospora sp-1), H (inoculation Acaulospora sp-2), I (inoculation Acaulospora sp-3), J (inoculation Acaulospora sp-4), K (a combination of all-Glomus sp), L (a combination of all Acaulospora sp), M (combined all-Glomus sp-sp and Acaulospora). Data were analyzed with a 5% level of variance followed by DMRT 5% level. parameters measured were AMF colonization, seedling height, dry weight, available P, pH and Al. Research results can be concluded that the inoculation of all AMF Glomus sp and Acaulospora sp gave the highest colonization 53.33%, increased soil pH 15%, decreased the Al 56% and increased the available P of 9.25%.

Abstract

Pollen of oil palm is one of important components that might affect productivity of oil palm (Elaeis guineensis Jacq.). Viability and availability of pollen directly affect the quality and quantity of oil palm. The aim of this research was to evaluate the effect of storage container and time of storage to pollen viability. This research has been conducted at Seed Preparation laboratory of PT. Sampoerna Agro Tbk, PT. Bina Sawit Makmur Mesuji Kabupaten Ogan Komering Ilir. The experimental design being used was Factorial Randomized completely design with two factors were storage containers i.e. Pirex tube reaction (M1), Film Ampoule (M2), Vial bottle (M3) and Glass Ampoule (M4) and time of storage i.e. storage for 0, 1, 2, 3, 4, 5 and 6 months. Each treatment was replicated three times. Parameters being observed included pollen viability, potential of maximum growth and pollen growth rate. The results showed that storage container and time of storage influenced potential maximum growth significantly but there was no effect on pollen viability and pollen growth rate

Abstract

Manure enriched by rock phosphate (RP) and inoculated with biodecomposer very important to improve the upland fertility. Residual effects of applied manure can be used for the next growing season. The objective of the research was to investigate the residual effects of some kind of manure on sweet corn (Zea mays saccharata), dry matter (DM) and P production of stover on second growing season. A field experiment of completely randomized design with 7 treatments and four replicates. Level of P (RP), N (urea) and K (KCl) fertilizers was 66 kg P/ha, 200 kg N/ha, and 125 kg K/ha, respectively. All of manure application at 30 ton/ha and enriched with RP. The treatments at the first growing season were T0 (manure), T1 (manure +EM4), T2 (manure+starTmik), T3 (manure +stardec), T4 (manure granular+EM4), T5 (manure granular+starTmik), and T6 (manure granular+stardec). The sweet corn was harvested at 70 days, the stover was cut and measured for DM and P production. The result showed that effect of some kind of manure was not significantly different to sweet corn and DM production. Manure inoculated with biodecomposer resulted in signficantly higher of P production than without biodecomposer. Conclusion, all of manure resulted in similar on sweet corn and DM, except manure inoculated with biodecomposer resulted in higher of P production than without biodecomposer.
