Abstract

Aquaponic system is a cultivation method that combines fish and plant farming or aquaculture and hydroponics that are mutually beneficial (symbiotic mutualism) at one time. Aquaponic water level control to maintain water volume is still done using conventional methods. Therefore, this research aims to produce a good control system to control aquaponic water levels equipped with an on/off control system and can monitor water levels remotely. This research method includes designing a control system for water level, functional test and performance test of the control system to aquaponics as well as data loss test and network delay to Thinger.io platform. The parameter observed was the water level. The results showed that the on/off control system was able to regulate the water level with no overshoot, the settling time reached for a height of 20 cm was 9 minutes, a height of 25 cm for 22 minutes and for a height of 30 cm for 34 minutes and the steady state error that occurred was still within the tolerance limit. The IoT system using the Thinger.io platform implemented is able to send data and store data during the testing process, and the Thinger.io platform can monitor water levels remotely and provide data in excel format. The test results of lost data with an average of 1.81% and delay testing with an average of 0.88%, based on data mapped every 6 hours, the largest percentage of lost data and delay occurs at 00.00 -06.00 GMT +8.

Abstract

The post-harvest handling of corn involves threshing, the process of separating kernels from the cob. A corn shelling machine without husking offers advantages for both sellers and buyers by allowing manual sorting of good and damaged kernels before threshing. This study evaluates the performance of a no-husk corn sheller used in the Amali District, Bone Regency. Key parameters analyzed include fuel consumption, shelling capacity, percentage of damaged kernels, and cleanliness level at three different rotational speeds (500, 600, and 700 rpm). The results indicate that increasing the rotational speed leads to higher fuel consumption and improved shelling capacity. However, the percentage of damaged kernels decreases with higher speeds, achieving an average damage rate of 0.049%. Additionally, the cleanliness level of the shelled corn reaches an average of 98%, confirming the machine’s efficiency. These findings suggest that optimizing the rotational speed enhances both productivity and output quality, making the no-husk corn sheller a viable tool for post-harvest processing.
