The<br>research was conducted in Marga Mulya village Semangga District starts from September 2012 to<br>January 2013. The type of data in this research is the primary and secondary data. Data analysis<br>performed in this study is an analysis of the feasibility of farming by using the Revenue Cost Ratio<br>(R/C ratio). Results of the analysis of the feasibility of using a proportion of farm receipts and cost<br>(R/C ratio) with more than 1,5 criteria. Meraoke rice varieties with a variety of inorganic treatment<br>with treatment eligibility level or value of the R/C ratio of 1.55 which is lower if compared with the<br>rice varieties of organic semi Meraoke treatment value of R/C ratio of 2.06 and the Dyah Suci<br>treatment of rice varieties inorganic value of R/C ratio obtained at 2.70 and varieties of organic semi<br>commission of the Dyah Suci R/C ratio of 2.37 obtained rice varieties and inorganic treatment<br>Ciliwung R/C ratio of 3.45 and obtained treatment Ciliwung organic semi R/C ratio obtained by 2.14.</span> </p> 2018-09-24T00:00:00+07:00 ##submission.copyrightStatement## Blower Modification to Increase Bran Removal on Rice Polisher 2019-09-28T13:56:59+07:00 Ganda Guna Ngumbara Andriyono Andriyono Yosefina Mangera <p><span class="fontstyle0">The purpose of this research is to design the auxiliary blower that can be used to overcome the<br>blockage on the bran expenditure correct and to know the speed of the blower. The method of this<br>research consisted of the first step (literature study, proposal masking, equipment and material supply<br>and design the auxiliary blower tool), the second stage is the making of bran blower auxiliary tool, and<br>third step is the test (measuring wind speed in the blower using anemometer, comparing the level of<br>cleanliness of rice from rice bran, and recapitulation of tool making). The results obtained in the field<br>conditions 3.5-inch pulley of 16.6 m/s has a moderate wind speed so that groats are not much wasted.<br>The percentage of whole rice after using the blower on the second observation that is using the 2.5-<br>inch pulley of 98.12%, the third using 3.5-inch pulleys of 97.56%, the fourth using 4.5-inch pulleys of<br>95.70% and treatment before using blower 89.59%. Based on the recapitulation of the tool making, the<br>total cost of making the tool are Rp.2.505.500.</span> </p> 2019-09-28T00:00:00+07:00 ##submission.copyrightStatement##
