Abstract

In addition to food crops, peatland also has potential for vegetable farming, such as Brazilian spinach. The aim of this study is to determine the most effective combination of banana stem biochar and banana stem compost doses for the growth and production of Brazilian spinach, as well as to analyze the feasibility of farming on peat soil. The research was conducted from October 2024 to March 2025 on land owned by farmers in Banyu Urip Village, Tanjung Lago District, Banyuasin Regency, South Sumatra. The Complete Randomized Factorial Design (CRFD) method was used in the study and consisted of two factors. The first factor was the dose of banana stem biochar: 5, 10, 15 tons/ha. The second factor was the dose of banana stem compost: 10, 20, 30, 40 tons/ha. Based on the results, the application of a combination of biochar and banana stem compost interacted significantly in increasing plant height (cm) and number of leaves (pieces) at 3 WAP and 4 WAP, as well as the fresh weight of Brazilian spinach plants at harvest. The length and fresh weight of Brazilian spinach roots at harvest were influenced by the main factors of banana stem biochar and banana stem compost. The combination of banana stem biochar and compost did not significantly increase the pH of peat soil. Based on the farming analysis, Brazilian spinach is viable to cultivate and provides the highest profit by applying 15 tons ha⁻¹ of banana stem biochar combined with 30 tons ha⁻¹ of banana stem compost.

Moelyohadi et al., 2012. The Use of  Various Types of Biofertilizers on Cultivation of  Nutrient Efficient Corn Genotypes(Zea mays L.  in Marginal Dry Land. JLSO 1(1):31-39.The study aimed at  obtaining nutrient efficient corn genotypes that give the best response to various types of biological fertilizers at low-level doses of chemical fertilizer in marginal drylands. This study was conducted in the field trials of Agro Techno Park (ATP), the Ministry of Research and Technology, South Sumatra from May to September 2011. The experimental design used was SplitPlotdesign  with three replications. The main plot treatments consisted of: (H0): without biofertilizer, (H1): biofertilizer:-mycorrhizae and (H2): BPF biological fertilizers. Subplot treatments, consisting of three corn genotypes for the selection of efficient nutrient properties, are genotypes  B-41 (G1), L-164 (G2), S-194 (G3)  and onehybrid variety:BISI-816 (G4) as agenotypecomparator. Alltreatmentunitswere givenlow dosesof chemicalfertilizerthat is 50% of theATPstandarddose(200kgUrea, SP-36 50kgand 25kgKClha-1).  The results showed that mycorrhizal fertilizer produced the highest corn production, which is 6.08 ton dry seed / acre and genotype B-41 shows a more adaptive growth in marginal dry land with a production  of 7.27 tons of dry  seed /acre  and the combined treatment of mycorrhizal fertilizer and genotype B-41 gave the highest production  of 8.57 tons of dry seed / acre

Abstract

Gofar. 2012. Application of Hydrocarbonoclastic Bacteria Isolates from Mangrove Rhizosphere on Petroleum Polluted Soil. JLSO 1(2):123-129.This research was aimed at studying the ability of hydrocarbonoclastic bacteria to reduce total petroleum hydrocarbon of petroleum polluted soil. The hydrocarbonoclastic bacteria were isolated from rhizosphere of mangrove grown on petroleum contaminated soil in Sungsang, Sumatra Selatan. The samples were taken using a defined sampling method from the oil contaminated areas. Soil samples around the roots of mangrove plants were randomly taken in the contaminated    area.  Isolates obtained from the isolation and selection of bacteria from mangrove forests were overhauled at the laboratory-scale using oil-enriched medium following  a completely randomized design. Nine isolates of hydrocarbonoclastic bacteria were found to be  capable of growing on petroleum contained medium in vitro. Two best isolates in degrading petroleum hydrocarbon compound were Pseudomonas alcaligenes (I5) and Alcaligenes facealis (I8). P. alcaligenes and A. facealis were able to decrease TPH up to 63% and 70% respectively. The ability of these isolates in degrading hydrocarbon compound was 6.5-7.0 times higher than the control.
