Abstract

The decline in the quality of land caused by the use of inorganic fertilizers fueled the growth of organic farming. Organic farming requires a source of organic fertilizer which is very large. Needs a very large organic fertilizer requires a source of organic material that is widely available. today in eastern Kalimantan and oil palm industry is growing rapidly. The palm oil industry in addition to producing liquid waste also generates solid waste such as oil palm empty fruit bunches that can be used as a source of organic fertilizer. This study aims to determine the release of nutrients after the decomposition of oil palm empty fruit bunches using Banana?s Corm (Musa paradisiaca) Microorganisms.This research is descriptive methods. Assessment of the nutrients status in the compost TKKS using BPT Bogor (2009). The results showed that the pH of compost TKKS using Banana?s Corm (Musa paradisiaca) Microorganisms 8,54; C-organic 54,3 %; Nitrogen 1.8 %; Ratio C /N 31.5; P2O5 0,4 %, and K2O 1,59%.

Abstract

Sempor catchment area have many function, one of them is as a central of agricultural sector in Sempor sub district. The agricultural sector in Sempor catchment area hasn’t been able to catch up the optimal production. The production was only sufficient to supply farmer requirement. The research in order to agricultural development uncommon to do in Sempor catchment area. The research usually talking about the sedimentation process of Sempor basin whereas for the other problems weren’t gave much attention. Sempor catchment area has different characteristic on soil physic, chemical, and fertility. The research about the fertility capability soil classification system (FCC) on several sub catchment areas, Sempor catchment area need to be done in order to agricultural development. This research was used soil survey methods, and laboratory analysis. Result of this study shown that Sempor catchment area have different in soil fertility. Sampang sub catchment area has four FCC that is LR (≥45%), LCk (15‐30%), SC (30‐45%), and LC (8‐20%). Ketegan sub catchment area has three FCC that is LCk (15‐30%), SC (30‐45%), and LC (8‐ 20%). Kedungjati sub catchment area have four FCC that is LCk (15‐30%), SC (30‐45%), C (30‐45%), and LC (8‐20%). Kalikumbang, Kaliputih, Kedungwringin, and Sempor sub catchment area have two FCC that is LCk (15‐30%), and C (30‐45%), and Seliling sub catchment area have three FCC that is LCk (15‐30%), SC (30‐45%), and C (30‐45%). Key word : catchment area, the fertility capability soil classification system (FCC)

Abstract

The research was conducted to determine: 1) some chemical properties of oil palm empty fruit bunches (EFB) compost withbio-activator of water hyacinth local microorganism solution; 2) the best dose of local microorganism solution and compost of empty fruit bunches on the growth of soybean.The research was conducted from April until November 2016 in the Laboratory of Soil,Faculty of Agriculture,Mulawarman University,Samarinda.The experiment wasarranged in Completely Randomized Design (CRD) with five treatments and fivetime replications. The treatment was dose of compost,consisted of: 0 (control);200;400;600;and 800 g per polybag. Data were analyzed by analysis of variance (Anova) with F-test and if there was significantly different among treatments, continued withleast significant difference (LSD) test of 5%. Results of the chemical properties analysis of oil palm empty fruit bunchescompost with 300 mL local microorganism solution L-1as follows: pH 9.10; Organic-C 35.32%; total-N 1.34%; C/N ratio 26.36%; P2O5 0.08%; and K2O 1.88%.The dose of 800 g compost per polybag is the best dose of compost to the plant height at 14, 21, 28, 35, and 42 days after planting respectively 14.00; 18.32; 21.52; 24.54; and 27.36 cm, number of pods 8.80,and dry seed weight of soybean 1.99 g.

Abstract

East Kalimantan has a fairly extensive ex-coal mining area. Continuous mining activities cause severe land damage with a dramatically reduced nutrient. The application of organic farming can be one of the solutions to improve ex-mining land. One of the plants that can be applied is Situ Bagendit Rice. Rice Bagendit varieties are dry land rice which is resistant to pests and blast disease. The use of market waste, MOL golden snail, and Trichoderma. Sp as organic material can increase productivity in Bagendit rice plants there and be able to repair damage to ex-coal mine land. The aim of this study was to compare market waste, MOL golden snail and Trichoderma sp to Bagendite rice plant growth. This study used the RAL method (Completely Randomized Design) with 9 treatments and 3 replications. B0 control (soil without additives), B1 compost market waste and Trichoderma sp with a dose of 100 g/polybag, B2 market waste waste compost and MOL golden snail with a dose of 100 g/polybag, B3 compost market waste and Trichoderma sp with 200 g/polybag, B4 market waste compost and MOL golden snail with a dose of 200 g/polybag, B5 market waste compost and Trichoderma sp with a dose of 300 g/polybag, B6 market waste compost and MOL golden snail with a dose of 300 g/polybag, B7 market waste compost and Trichoderma sp with a dose of 400 g/polybag, B8 market waste compost and MOL golden snail with a dose of 400 g/polybag. The results showed that Trichoderma sp market waste compost fertilizer and golden snail market MOL waste compost each had a significant effect on the productivity of bagendite rice plants. In addition, MOL market golden snail waste compost with the best dosage of 400 g/polybag is able to produce harvested dry grain production of around 2.8 tons/ha.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh beberapa jenis bokashi menggunakan bioaktivator larutan mikroorganisme keong emas terhadap sifat kimia vermikompos dan menentukan jenis bokashi terbaik pada sifat kimia vermikompos.Penelitian ini dilakukan selama 3 bulan, mulai dari Januari hingga Maret 2015, bertempat di Fakultas Pertanian, Universitas Mulawarman. Penelitian ini terdiri dari 4 perawatan. P0 (tanpa bokashi), P1 (sayur bokashi), P2 (jerami padi bokashi), dan P3 (daun bokashi dari kacang plus pupuk kandang kambing).Hasil penelitian ini menunjukkan bahwa pemberian bokashi dapat meningkatkan pH, C-organik, N-total, rasio C / N, P-total, K-total dan Ca dalam kascing. Pemberian kacang jenis daun bokashi plus pupuk kandang kambing (P3) memiliki kandungan nutrisi pH 6,52, C-organik 9, 69%, N-total 0,95%, rasio C / N 10,20, P-total 1,544%, K-total 1,419% dan Ca 4.710% tertinggi dibandingkan dengan perawatan lain.
