Abstract

Installation of spotlights and LED strips with automatic operation at the entrance gate of the SPI Cluster RT.10 RW.04 Bandungrejosari Village, Sukun District Malang City is based on the absence of lighting contained in the writing of the Sukun Pondok Indah Cluster (SPI) so that many guests or couriers who are not aware of the housing. With the installation of spotlights and LED strips, it is hoped that the writing on the gate of the Sukun Pondok Indah cluster will be bright and visible so that guests or couriers can immediately know about the housing. Then people can see when installing spotlights and LED strips with automatic operation, they hope that people can install lighting installations automatically in their respective homes correctly and according to standards. Then people do not need to operate the ON / OFF spotlights and LED strip every day. That way, the benefits of installing spotlights and LED strips with automatic operation, people don't need to ON / OFF the lighting every time.

Abstract

This research is focused to help peoples in remote areas who do not have electricity supply from PLN, but have sources of water flow in rivers. The main objective of this research is to create a picohydro hydroelectric power plant with a floating turbine to utilize the kinetic energy of river water flow in areas that have not been supplied with PLN electricity. The flow of water in the river will rotate the turbine, which in the end the rotational power is channeled through a pulley and belt system, which eventually turns an alternator. The alternator used is a three-phase AC alternator. Then the AC current will be rectified by the bridge rectifier to then be used to charge the battery and go to the load. In addition, in this study, the ability of the pico-hydro system to supply electrical energy will be tested to be able to run 12 V DC electrical loads and charge 12 V batteries.

Abstract

Coffee is one of the beverages with a distinct flavor profile. Coffee production continues to grow in response to community demands. A wide variety of coffee flavors have been developed, necessitating an effective coffee processing method, such as roasting. While many coffee production processes employ roasting machines with high capacities, smaller industries may incur losses when using such machines due to their production needs, which involve creating new coffee flavor samples. To address these challenges, a solution is proposed: the creation of a drum-based coffee bean sample roasting machine that utilizes the convection method. The machine manufacturing process involves calculating the drum capacity, heater specifications, motor rotation, and air flow. A 2000 Watt heater is chosen, accompanied by a maximum drum capacity of 250 grams. The driving motor is a 12 V DC motor. The combined power of the motor components totals 1520 Watts, and the overall heating capacity can achieve temperatures of up to 300ºC. Performance testing of the roasting machine is conducted under conditions where all components are functioning correctly. The final roasting results exhibit even distribution, with a preheating temperature range of 190-200ºC for approximately 15 minutes roasting time.
