Rice bug (Leptocorisa oracorius F) is one of the most dangerous pests for paddy commodities (Oryza sativa) in the world. The use of liquid smoke was popular among local farmers to control rice bug. A coconut shell is the main source for making liquid smoke. This research aims to analyse rice bugs' mortality and antifeedant activity when dipped with coconut shell liquid smoke. The liquid smoke's effectiveness was measured by dipping paddy (5 grams in weight) that is previously soaked with coconut shell liquid for 20 seconds. The liquid smoke was prepared in various concentrations, ranging from 0% as a control; 0.50%; 0.75%; 1%; 1.25% and 1,50%. Observations were made at 24, 48, 72, 96, 120, 144 and 168 hours. Data analysis was performed by one-way ANOVA test, using SPSS program followed by a 0.05 Tukey test to determine the significance of the rice bug pest mortality. The study resulted that the mortality values from low concentrations to high concentrations were 40%, 46.67%, 60%, 70%, and 80% over seven days. The antifeedant percentage of liquid smoke increased from low concentrations to high concentrations respectively were 10.14%, 15.15%, 31.03%, 46.15%, and 68.88% during seven days. The concentration of liquid smoke that has the highest mortality was 1.50%. In conclusion, 1.50% of liquid smoke showed the highest percentage of mortality and antifeedant activity with 80% and 68.88%, respectively. In the future, it is hoped to develop this model for commercial consumption and reduce reliance on chemicals to control rice bugs. The use of pesticides can do more harm than good, especially to the environmental system
The purpose of this study is to determine the effect of the company's financial ratio empirically, both partially and simultaneously on changes in profit. The selection of samples was conducted by purposive sampling method from 12 company samples obtained by 9 company samples. The study used data analysis methods with multiple linear regressions and performed classical assumption tests first.The results of this study showed that the Current Ratio variable partially had an influence and negatively on the change in profit. Based on the resultsof the t test witha t count of -3,341 fromthetable's t value of -2,030 and a significance level of 0.002 0.05. The Return on Assets variable partially has an effect and positives on the change in profit. Based on the resultsof the t test with at calculate of 12,978 ofthetable's t value of 2,030 and the significance level of 0.000 0.05. While the Debt to Equity Ratio variable and the Total Assets Turnover variable partially had no significant effect on the change in profit. Simultaneous testing showed that variables Current Ratio, Return On Assets, Debt to Equity Ratio,and Total Assets Turnover simultaneously had a significant effect on changes in profits. Based on the results of the test F with a significance value of 0.000 0.05 and Fcalculated 46.745 from the table Fvalueof 2.61. The variable influence rate of Current Ratio, Return On Assets, Debt to Equity Ratio and Total Assets Turnover simultaneously is 82.4%.

Asap cair tempurung kelapa dan sekam dengankonsentrasi 1% dapat menghambat pertumbuhan koloni jamur sebesar27,54% dan 16,88% secara berurutan, sedangkan pada konsentrasi 3%,5% dan 7%, kedua jenis asap cair ini dapat menghambat jamursebesar 100%.
This study aims to determine the effect of training on processing cassava and sweet potato products held at the Indonesia Centre for Agricultural Training (ICAT) of Ketindan and determine the correlation between the participants' areas of origin on improving the performance of agricultural instructors. This research method uses data sources that come from the field obtained by interviewing alumni, fostered farmers, colleagues, and alumni superiors with a survey using a questionnaire. The results of the data were analyzed descriptively and correlated using SPSS Software Version 18 for Windows. The general research results show that the training that has been carried out in 2014, 2015, and 2017 has an effect on increasing the performance of agricultural instructors by 63.20%. This is measured by 3 (three) indicators, namely 1) preparation of agricultural extension by 3.40 or 68.00%; 2) implementation of agricultural extension 2.77 or 55.40%; and 3) evaluation and reporting of 3.29 or 65.80%. The results of the correlation between the participants' regions of origin and the performance of the extension workers showed that the highest performance achievement was 77 and the lowest was 26. Thus, the extension workers could show good performance in disseminating the application of technological innovations for processing cassava and sweet potato products to farmers or their fostered business actors which affected increasing cassava and sweet potato production and productivity.
