Abstract

Renewable energy generated from sunlight (Solar Panels) can be formed as alternative energy that can be applied to a source of electrical energy in rice thresher equipment. The use of solar energy with a power of 240 WP through the object on the rice thresher is able to replace the rice thresher automatically which is more effective. The power generated by solar energy will be processed into a charging source for the Regulated Battery Charger which can be supplied at a voltage to the control circuit to drive the DC motor. The average voltage generated by solar energy is 0.000394 volts/lux with a maximum voltage of 36.2 volts and a DC motor of 350 watts. In addition, the speed of this rice thresher is 950.8 rpm and is able to produce very good rice cutting against the designed solar energy capabilities.

Abstract

ABSTRAKPengabdian masyarakat ini merupakan salah satu program fakultas kampus Politeknik Negeri Medan. Dengan adanya kegiatan nirlaba ini bertujuan untuk menjadi semacam kepedulian civitas akademika terhadap permasalahan masyarakat dan lembaga nirlaba yang menyalurkan tugas-tugas sosial untuk secara efektif meningkatkan kualitas hidup masyarakat. Sebagai tim pengabdian kepada masyarakat, kami berupaya memberikan kontribusi ilmiah dengan melaksanakan kegiatan pengabdian ini tentang penerapan teknologi mesin otomatis pencacah rumput berbasis motor listrik pada peternakan pak yasir di sunggal. Adapun kegiatan pengabdian masyarakat ini memiliki fokus penelitian terhadap penggunaan alat pencacah rumput manual maupun otomatis tetapi masih mempunyai kekurangan fungsi serta masih banyak masalah terhadap alat yang digunakan, terutama untuk yang alat mesin (otomatis) sangat boros terhadap bahan bakarnya. Alat yang biasa digunakan juga memiliki harga yang sangat mahal dan suara mesin yang cukup bising sehingga tidak kondusif dalam menggunakannya. Dengan demikian, melalui program kegiatan masyarakat ini akan memberikan alat yang sudah dirancang secara efektif kepada kelompok petani yang biasa berada di area persawahan maupun rerumputan guna dalam mengambil hasil rumput untuk hewan ternak nya maupun bisa di olah ke fungsi pangan yang lain. Alat mesin pencacah rumput ini juga sudah teruji sangat layak digunakan dan menghasilkan pemotongan rumput yang cepat serta ramah untuk lingkungan sekitar.  Kata Kunci : Penerapan, Mesin Pencacah Rumput, Motor Listrik

Abstract

Elevators are a crucial vertical transportation system in multi-story buildings, and the use of an appropriate control system can enhance operational efficiency, comfort, and safety. This study aims to design a control system for a 3-floor elevator using a Programmable Logic Controller (PLC) OPTA FINDER, which offers advantages in flexibility and ease of programming. The design process involved creating a control system schematic, programming with ladder diagrams, and testing on a small-scale elevator model. The test results demonstrated that the system could operate the elevator with fast and accurate response in detecting floor positions, controlling automatic doors, and responding to emergency conditions. Furthermore, the PLC OPTA FINDER proved reliable in managing elevator system components and facilitating program modifications without requiring hardware changes. This control system also contributes to energy efficiency through optimized motor speed regulation. Thus, the implementation of the PLC OPTA FINDER provides an effective and safe solution for modern elevator control systems.

Abstract

The researcher wants to make a KWH meter monitoring tool with estimated usage costs so that the tools he makes can help the community to minimize costs in the electricity consumption area, especially in the workshop room located on the 1st floor of building C at Medan State Polytechnic. The long-term goal of this research is to develop an Internet of Things (IoT)--based KWH meter monitoring tool that can read current, voltage, frequency, power factor, and power consumption. This utilization shows the use of costs that have been incurred in real-time by displaying the results on the LCD and can also be from the user's mobile phone. In this study, the strategy used in the energy management framework was determined using SWOT analysis. From the results of the measurement and monitoring of electrical energy consumption obtained the results that, energy management is carried out by applying Standard Operating Procedures for the use of electrical energy in the electrical engineering workshop room in order to save more minimal energy consumption with a large error (Error) PZEM in measuring Voltage is 0.0198% in measuring Current is 0.612%. in measuring Cosphi is 0.01%. in measuring Frequency is 0.003%. in measuring Power is 0.183%. And the average measurement error rate is below 0.5%, namely 0.23%.

Abstract

Researchers want to make a kWh meter monitoring tool with estimated usage costs so that the tools made can help people to minimize costs in electricity usage. The purpose of this research is the creation of an IoT-based kWh meter monitoring tool that has the ability to read current, voltage, frequency, power factor and power usage that flows and shows the use of costs that have been used in real time with the display results on the LCD and also on the user's smartphone. In the reading results of usage costs (Rp) on the tool and PLN there is also a difference of Rp. 12,000, where the reading results on the tool are also lower than the results of the payment slip provided by PLN. The cost reading error rate on the tool is 4.4% with a reading accuracy rate of 95.6%.
