Abstract

This project was developed to create an automatic system that can control a lamp based on the surrounding light conditions. The system uses an LDR (Light Dependent Resistor) sensor to detect light intensity and an LM324 IC as a comparator to determine when the lamp should turn on or off. When the ambient light decreases (such as during nighttime), the resistance of the LDR changes and sends a signal to the LM324 circuit. The main purpose of this system is to enable the lamp to automatically turn on when it gets dark and turn off when it becomes bright again, without the need for manual switching. In this way, the system helps to save electrical energy and improve lighting efficiency, especially in areas that are often forgotten to be turned off, such as porches or garden lights. Based on the testing results, the system functions properly and responds quickly to changes in light. The circuit is also stable and easy to build, as it uses simple and commonly available components. Overall, this system is suitable for various lighting automation purposes in residential areas as well as public spaces.

Abstract

Program pengabdian masyarakat yang dilakukan oleh Politeknik Negeri Indramayu (Polindra) berkolaborasi dengan eFishery bertujuan untuk meningkatkan produktivitas petambak udang melalui inovasi teknologi ramah lingkungan. Salah satu kegiatan utamanya adalah penyerahan alat pemberi pakan udang otomatis berbasis tenaga surya kepada Badan Usaha Milik Desa (BUMDes) di Desa Pangkalan, Kecamatan Losarang, Kabupaten Indramayu. Alat ini dirancang untuk memberikan pakan secara otomatis sesuai jadwal, sekaligus mengoptimalkan pemberian pakan pada udang. Alat ini juga mengintegrasikan sistem tenaga surya sebagai solusi atas keterbatasan listrik PLN di lokasi tambak. Penerapan alat pakan otomatis ini diharapkan mampu meningkatkan produktivitas petambak, efisiensi kerja petambak, kualitas panen, dan pendapatan masyarakat.

Abstract

This study aims to design a thermoelectric system for a coolbox utilizing additional ice pack components for mango storage by leveraging a TEC1-12706 Peltier element based on IoT technology. Thermoelectric is an energy conversion technology that directly converts thermal energy into electrical energy and vice versa through thermoelectric materials. The system operates based on the Peltier effect, which generates a temperature difference between two sides of the material when an electric current is applied. Based on the test results, the developed thermoelectric system achieved a cabin temperature of up to 12.6 ºC within 60 minutes, according to the ideal storage temperature requirements for mangoes (12–15 ºC). The addition of an ice pack plays a significant role in accelerating the temperature reduction inside the cabin. The cold sink and heatsink components function effectively in absorbing and releasing heat to the environment. This system achieved a COP of 0.60 with an efficiency of 60%. The thermoelectric system has also been successfully integrated with IoT technology through the Blynk application, enabling users to monitor temperature and humidity in real-time via an internet-connected smartphone, thereby facilitating the control of mango storage conditions.

Abstract

Air bersih merupakan kebutuhan mendasar bagi manusia, sehingga kualitas air perlu dipantau secara periodik. Salah satu parameter kualitas air yang penting adalah tingkat kekeruhan. Kekeruhan tinggi menandakan keberadaan partikel padat tersuspensi yang dapat membahayakan kesehatan. Penelitian ini bertujuan merancang dan menguji sistem otomatis pengendali kecepatan motor pompa air berbasis mikrokontroler Arduino Nano dengan acuan tingkat kekeruhan air. Sistem menggunakan sensor turbidity untuk mendeteksi kekeruhan dan sensor infrared untuk memantau kecepatan motor. Arduino mengatur kecepatan pompa melalui driver LSA-002 berdasarkan tingkat kekeruhan yang terdeteksi. Data monitoring ditampilkan secara Real-Time melalui platform Node-RED. Metode penelitian meliputi perancangan rangkaian, pemrograman mikrokontroler, perakitan sistem, dan pengujian. Hasil menunjukkan bahwa sistem dapat bekerja secara otomatis dan efisien dalam mengontrol kecepatan motor sesuai kekeruhan air, serta berhasil menampilkan data monitoring secara dalam jaringan.

Abstract

The rapid development of technology in the era of the Industrial Revolution 4.0 has driven the education sector to continuously adapt to the evolving demands of digital-based industries. One of the key technological innovations supporting this transformation is the Internet of Things (IoT), which enables data acquisition, real-time monitoring, and remote control of systems through internet networks. In response to these developments, a community service program was conducted to enhance the understanding and technical skills of students at SMK Negeri 1 Sindang through the provision and utilization of an IoT Trainer Kit Simulator as a practical learning medium. This activity aimed to bridge the gap between theoretical knowledge and industry-relevant technological applications by introducing students to hands-on IoT system implementation. The program included demonstrations and guided practice on the use of sensors, microcontrollers, and web-based monitoring platforms to simulate real-world industrial scenarios. The results indicate that students showed high enthusiasm and active participation throughout the activity. Moreover, participants were able to grasp the fundamental concepts of IoT systems, understand component integration, and recognize the relevance of IoT applications in supporting automation and digital transformation. Overall, this community service activity contributed positively to strengthening students’ digital competencies and preparedness for the demands of the contemporary industrial and technological landscape.

Abstract

This study discusses the design and implementation of a control system for a water pump used to inject PAC solution into raw water, thereby producing treated water that meets quality standards. The pump’s operating duration is adaptively controlled based on the turbidity level of the water to be clarified. The system employs a turbidity sensor as the input signal, which generates data to be processed by a NodeMCU-ESP32 device serving as the central controller. Subsequently, the controller issues commands to the water pump, functioning as the actuator, to perform the PAC injection process. Experiments were conducted on three types of water sources, namely river water, paddy field water, and groundwater, with initial turbidity levels of 29, 35, and 64 NTU, respectively. The results showed that all water samples were successfully clarified to a turbidity value of 0 NTU within 47, 120, and 137 minutes, respectively. At the beginning of the treatment process, turbidity value readings exhibited fluctuations due to the initial mixing of PAC solution with raw water. However, the turbidity values steadily decreased once the PAC and suspended particles were fully settled. To facilitate monitoring, the system is equipped with an IoT feature via the Firebase platform, which displays numerical indicators including water volume, turbidity level, pump speed, pump operating duration, and water status classified according to clarity. This innovation is expected to contribute as an effective water purification automation technology, expecially for small- and medium-scale industries.
