Abstract

Penelitian ini dilakukan dengan tujuan untuk mengetahui pengaruh pemberian kompos pada budidaya kacang tunggak terhadap erodibilitas tanah. Penelitian ini juga diharapkan dapat memperbaiki sifat fisik tanah dan mengurangi erosi suatu tanah. Rancangan yang digunakan adalah Rancangan Acak Kelompok di mana perbandingan tanah dan kompos terdiri dari 6 tingkatan yaitu tanah 100%;  97,5% tanah : 2,5% kompos; 95% tanah : 5% kompos; 92,5% tanah : 7,5% kompos; 90% tanah : 10% kompos; 87,5% tanah : 12,5% kompos; dan 85% tanah :15% kompos. Penelitian diulang sebanyak 3 kali. Parameter yang diamati dalam penelitian ini adalah sifat fisik tanah antara lain: struktur tanah, permeabilitas tanah, tekstur tanah, dan sifat kimia tanah yaitu bahan C-organik tanah, maupun penentuan nilai erodibilitas tanah. Hasil penelitian ini menunjukkan bahwa perlakuan kompos pada tanah dalam budidaya kacang tunggak berpengaruh nyata terhadap tekstur tanah, permeabilitas tanah, dan bahan C-organik tanah tetapi tidak berpengaruh nyata terhadap struktur tanah. Hasil penelitian menunjukkan perbandingan tanah dan kompos pada budidaya kacang tunggak85% : 15% merupakan perlakuan terbaik untuk mendapatkan nilai erodibilitas tanah yang rendah.   This research was conducted to determine the effect of provision compost in cowpea cultivation against soil erodibility. It was also expected that the research can improve soil physical characteristics and reduce soil erosion.The design used during this research was randomized group design with the ratio of soil and compost. Ratio of soil and compost consists of six levels; soil 100%, 97.5% soil: 2.5% compost, 95% soil: 5% compost; 92.5% soil: 7.5% compost 90% soil: 10 %compost; 87.5% soil: 12.5% compost and 85% soil: 15% compost. The research was repeated three times. Parameters observed in this study were the physical characteristics of soil, those are: soil structure, soil permeability, soil texture and chemical characteristics of soil that is C-organic material, as well as the determination of soil erodibility values.The results of this research showed that the ratio of soil and compost at cowpea cultivation significantly affected on soil texture, soil permeability, and C-organic materials; however it did not significantly affect the soil structure. Therefore, the best ratio of the soil and compost in cowpea cultivation is 85%: 15% to produce low soil erodibility values.

Abstract

This study was conducted to determine the legowo distance studies in rice farming systems legowo row. This study is also expected to get the optimal distance legowo on legowo row planting system to improve the productivity of rice in Subak system. This research is divided into 5 treatment, the treatment in accordance with local farmers distance of 28 cm ; legowo 6:1 with wide legowo 1.25 x 28 cm ; legowo 6:1 with wide legowo 1.50x28 cm ; legowo 6:1 with wide legowo 1.75 x 28 cm ; legowo 6:1 with wide legowo 2 x 28 cm. This study was repeated 3 times. Parameters observed in this study ware : microclimate include: ambient temperature. The results suggest the application of legowo 6:1 cropping systems with a wide range legewo difference in each treatment shown to affect the relative humidity.

Abstract

This study was conducted to determine the effect of planting System of Rice Intensification (SRI) and legowo 6:1 row planting system of the microclimate and the rice plants productivity. This study was divided into 4 treatments with 3 replications, ie treatments conventional techniques, SRI method of planting, application of legowo 6:1 row planting system, and combination of SRI planting method and legowo 6:1 row planting system. The results showed the application of SRI planting method and legowo 6:1 row planting system not affecting the microclimate conditions, but affecting the productivity of riceplants. The results also showed that treatment K3 applying SRI methods combined with legowo 6:1 row planting system is the best treatment compared with other treatments.
