Excessive fertilization and pesticides will lead to soil and water receives more weight than chemical content,which resulted in pollution of the environment in which the growth of plants. This study aims to determine the nitrate content in the roots , stems and leaves of cabbage and nitrate in agricultural land in the village Plumbon, Tawangmangu Karanganyar. This study is a descriptive survey , which determines the content of nitrates in vegetables cabbage. This study was performed on March until September 2013. From research to know that the concentration of nitrate (NO 3-) at a depth of 0 cm -20 cm ranged between 10.98 ppm - 70.32 ppm, the accumulation of nitrate (NO 3-) at a depth of 20 cm - 40 cm ranged between 20.21 ppm - 240 ppm , the accumulation of nitrate (NO 3-) at a depth of 40 cm - 60 cm ranged between 20.53 ppm - 180 ppm. Accumulation of nitrate (NO 3-) at this depth is affected by the process of leaching and leaching of nitrate in the soil layer above it. Accumulation of nitrate in cabbage leaves are below the limits Decision No. 1168 / Men / Per / 1999 on food consumption , but the roots are already exceed the quality standards set..

Rubber plant productivity is affected by production factors such as amount of labour, amount of land area, number of productive tree, manure and rainfall. Production factors must be controlled to meet optimum rubber production, due to the increasing need of rubber. Rubber consumption on 2009 is 9,277 millions ton, while on 2010 increase become 10,664 millions ton. World crude rubber is able to provide 9,702 millions ton on 2009 and 10,219 million ton on 2010. Factor that influence rubber harvest result is the benchmark to get the decision to support the rubber achievement harvest optimally. The purposes of this research is to know the production factor that influence rubber production in PT Perkebunan Nusantara IX (PTPN IX) Sukamangli estate. This research used descriptive analytical method. The data analysis uses multiple linear regresion with dummy. The regression analysis showed regression equation do not contain symptoms multikolinier, autocorrelation, heterokedastisitas. While the production factor significantly rubber production are amount of the harvesting of labour, amount of land area, the number of tree/hectare, cost of production, Ethrel stimunlansia, dummy tapping system and dummy tapping technology. Based on regression analysis, production factors that partially significantly influencing the rubber production is the harvest of labour, amount of land area, the number tree/hectare, cost of production, Ethrel stimulansia, dummy tapping system and dummy tapping technology. Keywords: production factors, rubber production, multiple regression, ARIMA

The aims of research is to find out the outpouring of hours of labor, the contribution of labor “Borong Prestasi” (TKBP) to the family income and factors affecting labor “Borong Prestasi” income. The basic method used is descriptive method. Respondents are took in stratified random sampling with the number of respondents as many as 52 people. The data used are primary and secondary data. Data collected by interview, observation and recording. Based on analysis of data on average hours TKBP is 5,2 hours per day. TKBP contribution to the family income is 40 percent of TKBP income amounted Rp 595.942 to total family income amounted Rp 1.486.519. R2values were obtained using multiple linier regression model for 0,957 means that the independent variable the number of jati wood obtained, the outpouring of hours of labor, length of work and age affecting to TKBP income in post-harvest handling jati wood is 95,7 percent, while 4,3 percent is influenced by other variables outside the model. F test result showed that the number of jati wood obtained, the outpouring of hours of labor, length of work and age together are very significant for TKBP income. T test result showed that the variable of the number of jati wood obtained significant and the outpouring of hours of labor significantly effect for TKBP income, while the variable length of work and age is not significant on TKBP income.Keywords: contribution, jati wood, labor “Borong Prestasi”, Blora Regency
