Abstract

This research aims to design a control system for a Peanut Grinder based on a 135 Watt AC Motor, intended to assist small and medium-sized food business entrepreneurs who utilize peanut ingredients. The purpose of this device is to enhance production efficiency in the preparation of peanut-based condiments, replacing the manual and time-consuming process with an automated system capable of sorting peanuts into fine and coarse textures as desired. By utilizing a 135 Watt AC Motor obtained from a washing machine as the main driving component, the design aims to reduce costs by reusing existing components. The control system will encompass mechanisms for grinding peanuts efficiently, ensuring user safety, and regulating motor speed and grinding duration. This research emphasizes environmental friendliness by repurposing unused components. Overall, the proposed Peanut Grinder aims to benefit UMKM entrepreneurs by streamlining production processes and enhancing productivity in the peanut-based condiment preparation.

Abstract

Electrical energy plays a much needed role in people's lives and economic development. Alternative energy potential, especially water energy, is a solution to utilize it as an energy source. Pico Hydro Power Plant is a tool or medium that uses water. At this time a hydro power generation system is being developed that produces electrical energy, one of which is using a pico hydro generator where the flow rate of water can be converted into electrical energy. In the water piping system at home it is used as a source of electricity, namely where the water reservoir as a reservoir for clean water with water conditions that are affected by the water flow rate can drive a pico-hydro generator turbine. In this research, the data collection process was obtained with a process of taking every 2 minutes for 40 minutes, it obtained an average water discharge of 8.75 L/s with a cross-sectional area of ​​0.0531, so the pico hydro generator can produce an average voltage of 8.88 Volts where the output results are step Up for battery charging and the average power is 10.60 watts on the battery using 3 loads and this research can be used for home lighting.

Abstract

SCADA (Supervisory Control and Data Acquisition) is a system that can supervise, control and acquire data on a plant. This system uses a computer to display the status of sensors and actuators in a plant, display them in graphical form and store them in a database. Generally, this computer is connected to a Programmable Logic Control (PLC) controller through a certain communication protocol (serial communication). This Engineering Practice Report discusses the improvement of the Jakarta flood control monitoring system uses the SCADA system where currently the use of SCADA is only limited to the visual monitoring display of CCTV cameras with water level elevation notifications and risk level indicators arising from the data received. In the design of the SCADA system in pump houses or flood pump sub-polders in locations spread throughout DKI Jakarta that exist today, especially in the current projects implemented, namely JGC Marunda Sub Polder, Adyaksa Pump House and Tipala Pump House.

Abstract

The Pagedangan Tangerang Overpass Bridge is one of the transportation infrastructure in the Tangerang area. The installed electrical loads include lighting loads (lamps) and power loads (which of course require a fairly large electrical power supply. The electrical power installed on the Pagedangan Overpass Bridge is 20,300 W. The power supplied from PLN is 33,000 VA from PLN and the total power capacity of the transformer is 37,500 VA. The results of the drop voltage analysis calculation for the PJU lighting load are 5,530 VA. For the analysis results of the drop voltage of 2.00 V, the voltage drop percentage is 0.42% and the conductor power loss is 12.12 W, the power loss percentage is 0.27%.

Abstract

Internet of things (IoT) is a requirement that is being developed a lot in smart homes today. Currently, many technology developers create smart devices that can make human work easier. Smart home systems are one of them. In a smart home system, physical devices can communicate via the internet network or other near cable networks to monitor or control devices in a house or building. In order to be able to monitor or control the physical device is integrated with sensors and actuators. One implementation of a smart home is controlling the light intensity of the lights which can be adjusted using the sleader command on Blynk IoT which is installed on the smartphone. The aim of this research is for users to be able to control the light intensity of house lights by using the sleader command on the Blynk IoT application by house occupants. The method used in this research is IoT. IoT-based communication methods allow data exchange between devices. The result of this research is that a lighting control system can be built using Blynk IoT. A feature has been added to this system to control the electrical power that will enter the lamp, so that it can regulate the light intensity according to needs. The success of the system is influenced by the Blynk IoT response when giving a signal to the Node MCU 8266 and the DIMMER response when receiving a command signal from the NODE MCU8266.
