Abstract

Tittle :  Effectiveness of Indigenus Bacteria in The Composting Process of Garbage and Rice Straw. The purpose of this research is to find out of the effectiveness of Indigenous bacterium  on  time of decomposition and quality of  litter of peanuts and rice straw compost. This research used Completely Randomized Design (CRD) from 2 factors. The  First factor consist of 3 levels, litter of peanuts 75%+rice straw 25% (D1), litter of peanuts 50%+rice straw 50% (D2), litter of peanuts 25%+rice straw 75% (D3). Second factor consist of 3 levels, activator dose 0ml/kg (A0); 0,5 ml/kg (A1), and 1 ml/kg (A2). Data were analyzed with F Test or Kruskall-Wallis and continued with Duncan Multiple Range Test (DMRT) level 5% and Regression Test to know correlation among various variables. The result of this research is hows that the application of compost material and activators dose can decrease time of decomposition, in treatment combination D3A1 is the best quality compost with C Organik, C/N, Total NPK, and pH almost same with SNI in 60 days incubation.

Abstract

Tittle : The Evaluation of Soil Chemistry Fertility  In Dry Land Of Samin Sub Water Shead Area Kabupaten Karanganyar. The purpose of this research is in order to learn the parameter of the soil chemistry fertility based on the plants need which is planted in a dry field of Samin  Sub Water Sheet Area kabupaten Karanganyar and to learn the best of soil management alternative which is needed to keep the parameter of soil chemistry fertility in a good level. This research was done in September 2006 until April 2007. The design research of this research is qualitative descriptive phenomenology, by field survey and supported by quantitative laboratory analysis. The research variables are parameter of soil chemistry fertility (Organic C,  total N, C/N ratio, available P,  available K,  available Na, available Mg, available Ca, CEC, base saturation, pH H2O) and the soil management which is usually done by farmers (practice in cultivating the field,  fertilizing, kinds of plant which are planted, system of planting). The data analysis for parameter of soil chemistry fertility is matched with the need of plants grown and  soil management which usually done by farmers used triangulasi. The result of this research is  that the parameter of soil chemistry fertility which have fulfilled the plants need  are Ca and Mg. They have fulfilled the plants need in all LMU (Land Map Unit). The parameter of soil chemistry fertility which have exceed fulfilled the plants need  are fertilizing N and K. They are too much in all LMU.  The parameter of soil chemistry fertility which has not fulfilled the characteristic of plants are the high P deficiency caused by P adsorption in all LMU ; the level  of CEC is medium in all LMU except in LMU 1 and 3; the level of Organic C is medium in LMU 3, 4 and low in LMU 8, 9; the level of C/N ratio is high in LMU 1 and very high in LMU  5 (value >20); the level of soil pH is too acid for Mustard green, Green onion in LMU 6, 7, 8, 9 and too acid for Onion, Carrot in LMU SPL  8. Best alternative of  soil management needed are fertilizing N and K.They must be matched with the need of plants in all LMU; giving silikat (Si) for decreasing P adsorption in all LMU; giving organic fertilizer (cow manure, dose 20 ton/Ha), that must be maintained or increased in all LMU;  giving lime for increasing pH in LMU 6, 7, 8, 9.

Abstract

Title : Study of Erosion Hazard on Upland in Samin Sub Watershed, Karanganyar Regency. Samin sub watershed at Karanganyar District, Central Java has been degraded by erosion. The shed needs to be managed seriously. This research was done at Samin sub watershed at 650 – 1800 above sea level from June to November 2006. The aim of the research is studying erosion hazard on each land unit in Samin sub watershed and land management have been done farmer. This research used phenomenology qualitative description method by interpretation of theme maps and Iconos image satellite, and survey. Soil and land management sampling method was done by purposive sampling. The result of this research are land in research area very sensitive to occur land degradation because erosion hazard in light until very heavy; intercropping system in land unit 1, 2, 3, 4, 5, 6, 7, and 8 is the best method to land conservation and diversification of agriculture yield; soil management method and intercropping system have been done by farmer are the best of land conservation Keywords: Erosion, Samin Sub Watershed, upland, intercropping, soil management
