Abstract

The rice thresher machine is an important part of the rice processing process. Before the harvesting process, the rice fields are drained for 7-10 days before the harvest period by using a sharp sickle to cut the base of the stems, then the harvest is stored in a container or lined place. The low application of cultivation technology can be seen from the large potential gap between production. With the creation of this system, the process of threshing rice from the stalks can be done automatically, so that this system is expected to be able to provide the process of threshing rice from the stalks to be faster, easier, more efficient and safe for workers. data from the presentation of rice tresher slender yields 223.17 S, at puly rpm the average value produced is 32.82 S, with an average voltage of 11 V and an average current of 0.18 A. 9.13 minutes, with initial grain weight of 15 kg with an average threshing yield of 6.6 kg, with a threshing capacity of 42.2 kg / hour. And the current and voltage data on the solar panel and the resulting charging, the highest voltage is 12 V with a current of 1.69 A which occurs at 12.30 Wib.

Abstract

Liquid level control is a regulatory system that is widely used by the petrochemical industry, paper mills, and steam power plants (PLTU). Fuzzy control techniques have light computing capabilities and do not require knowledge of the parameters of the system. The purpose of this research is to design and design a device that can make it easier to adjust the liquid level in the storage tank and observe the fuzzy control performance. Control is done by adjusting the valve opening in the storage tank. From the results of this study, data on setpoint 56 is obtained, the valve is at an angle with all open status (BS), at the first second or 1 second, and at set point 41, the valve is at an angle with a half-closed status (SN), in the 13th second, and the valve will be closed all (NS), if the valve is at an angle at the set point 29, with a time of 1620 seconds or 27 minutes. Based on this research, the proposed system is able to control the water level in the tank using fuzzy control.
