Abstract

Title : Study on Effectiveness of Nitrification Inhibition in Rhizosphere of Brachiaria species on Ultisol. It has been known for some plant species Brachiaria (Brachiaraia decumbens, Brachiaria humidicola , and Brachiaria brizantha ) that have been studied has been hoen to effectively inhibit nitrification from that rhizosphere activity. Therefore it is necessary to further resarch the cultivation of other plant Brachiaria species such as Brachiaria mutica , Brachiaria decumbens and Brachiaria humidicola, to determine the effectiveness as a barrier to the rate of nitification that carried out by the method of pot experiments with functional relationship variables approach based on sampling and nondestructif Completely Randomized Design ( CRD ) consisting of plant species Brachiaria factor . and various doses of N fertilizer is 100 kg / ha , 150 kg / ha , 200 kg / ha . Results of this study indicate that 1 ) Brachiaria mutica , Brachiaria decumbens and Brachiaria humidicola , very significant on nitrification potential , but the treatment of a wide range of doses of fertilizer N is not a real effect on nitrification potential . 2 ) Highest nitrification potential value in the treatment Brachiaria mutica in the amount of 5,114 mg NO2- / g soil /5hour , while the lowest value of the potential nitrification in plants Brachiaria humidicola is equal to 0,414 mg NO2- / g soil /5hour . 3 ) Of the three treatment plants Brachiaria sp . in that the treatment plant can Brachiaria humidicola considered the most effective in inhibiting nitrification.

Abstract

Title : Mapping of Paddy Soil Quality in Industrial Area Bengawan Solo Watershed in Karanganyar Regency. The aim of this research was to find out rice field quality in industrial area in Karanganyar regency. The problem formulation of the research was that the industrial activity in the industrial area in Karanganyar regency gave pressure to the rice field quality. The research method was descriptive exploration. It was conducted by determining Soil Map Unit (SMU) in research location though survey, getting sample based on purposive sampling method, conducting laboratory analysis for each selected soil function indicator (Minimum Data Set/MDS), conducting MDS scoring to discover the Soil Quality Index (SQi), and levelling SQi in each SMU. The dynamic factors to be observed to discover their influences for soil quality were fertilizing process, organic substance added, and plant rotation as soil management system. The result of the research is that SQi research location has about moderate (4.4-6.6), high level (6.6-8.8) and very high level (8.8-11). Based on stepwise regression test through Minitab 13 software, the most influenced indicators for the soil quality are bulk density, organic soil carbon, and available N. Fertilizer dosage application for next planting season SMU 1 was 263.23 kg/ha urea, SMU 2 379.43 was kg/ha urea, SMU 3 was 337.02 kg/ha urea, SMU 4 was 355.03 kg/ha urea, SMU 5 was 290.65 kg/ha urea, and SMU 6 was 305.67 kg/ha urea. Soil quality of excessive fertilizing (SQi = 8.14) higher than non excessive fertilizing (SQi = 7.85). Soil quality of non-organic substance addition (SQi = 8.38) higher than organic substance addition 5 ton cow manure/ha (SQi = 7.90). Soil quality of plants rotation with ground nut (SQi = 8.34) higher than non plants rotation (SQi = 7.77). Soil quality in SMU that contaminated by waste disposal (SQi = 7.37) was lower than control (SQi control inside = 7.87 and SQi control outside = 9.27). The research recommends some solutions for soil management system. The solutions are; determining industrial area based on rice field quality zone in SMU 5 (Dayu Village and Bulurejo Village, sub district of Gondangrejo), giving specific Fertilizer dosage application, conducting plant rotation with soybean, and adding decomposed organic substance or low C/N organic substance.

Abstract

TITLE : VERTISOLS N-MINERAL DYNAMICS IN SEVERAL LITTER QUALITY COMBINATION AND N-SWEET MAIZE UPTAKE. Problems are often found on farms in humid tropics that lack of balancing between number and availability of nutrients. The imbalance will lead to nutrients leaching, especially NO3- to the bottom layer. NO3- is the result of oxidation of NH4+ through a process called nitrification, hence it is important to control over the process as it. The purpose of this study was to determine the effect of litter quality Trimmings (based on the content of polyphenols and lignin) to the dynamics of N-NH4+ and N-NO3- land. This study is a field experimental with basic use Completely Group Randomized Design. The first factor is addition of Chromolaena odorata litter which represent high quality (lignin content 4.27 %, 17.12 % polyphenols), Tectona grandis litter representing low quality (lignin content of 14.54, 11.92 % polyphenols), and litter mixtures (Chromolaena odorata+Tectona grandis). The second factor dose of 5 Mg/ha, 12.5 Mg/ha, 20 Mg/ha. Analysis of the data using the F test, if the results of analysis of variance is significant, it forward to Duncan Test at α level = 0.05. The results showed that the addition of various quality litter significantly ( P

Title : Initial Assessment to Accelerate Recovery of The Affected Community Social Economic Mount Merapi Eruption Through The Cultivation of Silkworms. Research purposes to obtain the suitability of land for mulberry (Morus sp) in the affected area  2010  eruption  of  Mount  Merapi,  in  Balerante  Kemalang  Klaten  in  Central  Java.  This information  is necessary to create activities that can accelerate  the recovery of socio‐economic conditions of society through silkworm farming. The method used is an inventory of soil and land characteristics   through   field   surveys.   Step   (1)   an   inventory   of  climatic   factors,   soil   and topography to make the Land Unit Map (SPT). Stage (2) analysis of soil fertility in the laboratory to complement the characteristics of land that has not been obtained at the time of field survey. Stage (3) develop / describe the characteristics  of the land on each Land Unit on our soil. Stage (4) The process of evaluating the suitability of the land, the match (matching) characteristics  of land with mulberry plant growth requirements. The results of our actual and potential land suitability. This map is useful to provide guidance on the cultivation of mulberry plants. (Morus sp.),  Results  showed  that  most  of  land  unit  in  this  area  has  a  fitness  class  S2nr  (Quite  in accordance with the limiting nutrient retention)Keywords:  actual and potential land suitability, land characteristics, referrals, and cultivation
