Rice is a staple food for the people of Indonesia. Even though Indonesia is an agrarian country, Indonesia currently imports rice. In producing rice from rice there are obstacles. One of the main obstacles is post-harvest handling of rice with high yield loss during post-harvest. The amount of post-harvest loss occurs because most farmers still use traditional methods or the handling is not good and right. The purpose of this study was to determine the relationship between the capacity of the grinding machine and the quality of sosoh rice produced by the mill and to know the quality comparison of various types of grinding machine capacity. The research was carried out in the area of ??Wanasari Village, Tabanan-Bali to find out the quality of sosoh rice in the region. Head Rice is broken rice grains, both healthy and defective, which have a size greater than or equal to 6/10 part of the average length size of whole rice grains that can pass through the surface of the indented plate basin with a requirement of 4.2 mm hole size. Rice husk is a protective cover from rice grains which is separated from seeds during the grinding process. In the grinding process, there is rice which remains the husk which is caused by the power / rpm of the grinding machine which is too low because the friction force produced by the engine is not sufficient for the overall release of rice husk

The purpose of this study was to maintain minimum moisture content for switchgrass bales that were inoculated with Pleurotus ostreatus, a white-rot fungus, in order to start the breakdown of lignin for conversion to ethanol. The moisture content was to be maintained above 50%, which would be monitored using load cells to determine the weight. Three bales were used, and thermocouple wires and hose system were placed at four points inside each bale. In addition, the ambient temperature and relative humidity inside the building were monitored. Bales were inoculated with 1%, 2%, and 3% grain spawn by mass.  The inoculation was carried out by taking the bale apart in four places and sprinkling or spreading the fungal spawn over the bale. In order to continuously record the voltage readings from the strain gauges, NI USB-6225 data logger and National Instruments’ LabVIEW program was used to record and control the system. The develop automatic weighing and watering system had been able to maintain the bale moisture within the acceptable range and the fungus were observed growing.  Some issues related to voltage readings and uniformity of water distribution must be addressed for future work.
