This study aims to determine the performance of a plastic mulch hole making machine and its electrical power requirements. The study begins by providing speed variations on the engine sprocket, calculating the working capacity of the machine, and analysing the power requirements of the electric motor. The results showed that the engine sprocket could perform an optimal rotation speed for punching holes in plastic mulch. Most holes were created in the treatment with a rotational speed of 70 rpm, 16 holes per 5 m of plastic mulch. Overall, the performance of the plastic mulch punching machine has been able to provide fixes in making holes in mulch plastic. Of the three treatments, the speed variations of the plastic mulch punching machine provided perforations with the criteria of perfect and partial perforation. The highest percentage of ideal perforation was found in the treatment with a rotational speed of 29 rpm, 86%, and the lowest was found in the treatment with a rotational speed of 25 rpm, 9.3%. The coefficient of determination between the rotational speed of the machine and the performance of the machine to punch holes in the plastic mulch can be modelled by a polynomial equation.

The SRI (system of rice intensification) rice cultivation system can save water use and increase production. Besides, a controlled environment for monitoring such matters is important to be recorded to be able to investigate deeply the phenomena that occur. Therefore, a preliminary test to analyze the performance of the irrigation tank monitoring system and its environment was developed to monitor the effectiveness of rice cultivation watering at the research stage. A 400 mm × 700 mm bed planting fruit will be planted with water from two tanks with a 0.03 m3 capacity. A bed planting and tank were designed for two conditions, namely automatic and manual bed planting and tank. The control box of the monitoring system is placed in the water tank by monitoring water level, ambient temperature and humidity, water temperature, and illuminance from light. The performance test results of the monitoring system show that the device can function within normal limits. Sensors integrated with the ESP8266 NodeMCU development kit can be to record environmental conditions. The measurement data is then sent to the cloud via the internet and stored as a database. This database can be easily downloaded for further analysis if needed.
