Abstract

Design of an automatic exhaust fan prototype using a DHT11 temperature sensor is the manufacture of an electronic device to lower the temperature in a room and suck air in the room to be discharged outside the room, at the same time the exhaust fan draws fresh air outside into the room. In addition, the exhaust fan can also circulate air in a room, in order to stay healthy the room needs air circulation so that there is always a change of indoor air with fresh air from outside. This tool works automatically because this tool uses a temperature and humidity sensor type DHT11. This tool is still being made in the form of a prototype or initial model which is an example before making the actual tool. In this prototype, room temperature and humidity data are detected by the DHT11 sensor. The DHT11 temperature sensor detects the room temperature, then it is processed by the microcontroller then the exhaust fan will rotate to suck air out of the room by providing a calibrated digital signal. 30-50°C and a relative humidity measurement range of 20-90%. The input voltage is 12 volts and 5 volts is changed by the power supply. Arduino microcontroller works at a voltage of 5 volts and a voltage of 12 volts for the relay circuit and the exhaust fan will turn on at a temperature of more than 30 ° if the temperature is less than 30 ° C then the exhaust fan must stop rotating.

Abstract

Training kit an important role as a equipment for creating effective teaching and learning process. Training kit of reciprocating compressor is expected to facilitate students in understanding the theory and practice subjects related to the compressor. Compressor is a machine to increase air pressure by compressing air from the atmosphere. In simple terms the working principle, pressure and volume changes in a reciprocating compressor can be described in the form of a P-V diagram. The purpose of this study is to generate instructional media so that it understood the working principle and tested on reciprocating compressor one stage and two stages. The research method begins with the design of tools that are simulated visually through solidwork software, component preparation, assembly of learning media and equipments testing. The resulting frame is 1100 mm long, 600 mm wide and 800 mm high. The v-belt type is used according to the v-belt length of 41 inches for the one-level and 53-inch compressors for the two-level compressor. The diameter of the driven pulley also affects the rotation of the compressor shaft (N), the greater the diameter of the pulley then the shaft rotation also decreases. In addition to the rotation difference of the compressor shaft (N) which affects the piston displacement value, the number of piston also affects the Qth value.

Abstract

The Boiled Water Business (UAR) in Kertasari Village, Ciamis Regency is one of the micro-enterprises that focuses on providing hygienic drinking water through a boiling process. The production process, which is still done manually, leads to several problems, such as unstable water temperature, potential hazards for operators due to exposure to hot water, inefficient production time, and energy wastage. This research aims to design and create an automation and temperature control system based on a microcontroller, equipped with a cooling system, so that the water boiling process becomes more efficient, safe, and stable. This system is designed to automatically regulate the water temperature until it reaches boiling point (100°C) using a temperature sensor connected to the microcontroller, and automatically channels the water to the cooling system through a solenoid valve once the temperature is reached. The research method used is research and development with an experimental approach, which includes stages of system design, component selection, hardware assembly, microcontroller programming, and performance testing of the system in a real operational environment. The results of this research are expected to improve the efficiency of UAR production by minimizing manual intervention, reducing energy consumption, accelerating the cooling process, and lowering the risk of workplace accidents. With this system, the Boiled Water Enterprise can operate more optimally and consistently in meeting the hygienic standards of drinking water.
