Abstract

Solar energy is a type of renewable energy whose capacity is tremendous and fast in increasing its capacity so that it can be used for energy sustainability in the future. Solar panels are the only devices that can be used to utilize solar energy. Maximum Power Point Tracking (MPPT) is a method to maximize the power generated by solar panels. However, the problem with solar panels is the condition of partial shading, this occurs due to something blocking the rate of solar irradiation to the solar panel. The result is that there are 2 or more maximum power points from solar panels, the highest power is the Global Maximum Power Point (GMPP) and the other is the Local Maximum Power Point (LMPP). This partial shading condition cannot use conventional MPPT methods due to the complexity of finding GMPP. So, MPPT optimization method is needed, one of which is the Improved Whale Optimization Algorithm (IWOA). IWOA is a development of the Whale Optimization Algorithm (WOA) by applying the Sine-Tent-Cosine Map for the first time the algorithm works to be more effective in the initialization process of the algorithm population and can ensure a more uniform distribution of population distribution throughout the search space. IWOA will be applied to the MPPT system to achieve the GMPP of the solar panel under partial shading conditions.

Penelitian ini berfokus pada pengembangan sistem pengisian baterai yang efektif untuk lampu LED warna merah dan biru, guna mendukung karya seni menggunakan teknik anaglif double exposure. Sebelumnya, telah ada penelitian yang membahas tentang pembuatan teknik gambar dualisme dengan teknik anaglif double exposure, serta karya seniman Carnovsky RGB yang memamerkan hasil karyanya, namun masih belum banyak diketahui oleh masyarakat. Selain itu, penelitian terdahulu juga menunjukkan bahwa peningkatan berpikir kritis pada anak belajar dapat didukung dengan sistem pencahayaan yang tepat. Proyek  ini bertujuan untuk merancang sistem penggunaan buck converter sebagai pengisian baterai untuk lampu penerangan bervariasi 3 warna, masing-masing memiliki spesifikasi 12 Volt 5 Watt. Tegangan dari PLN akan digunakan untuk mengisi baterai 12,6 Volt 10 Ah. Sistem pengisian baterai ini menggunakan buck converter yang dikontrol melalui mikrokontroler STM32F103C8T6 sehingga dapat menghasilkan tegangan yang dibutuhkan oleh baterai dengan tepat. Monitoring daya melalui Bluetooth memungkinkan penggunaan lampu yang efisien. Hasil utama dari proyek ini adalah pengembangan sistem pengisian baterai yang berhasil dan dapat memaksimalkan fungsi lampu warna merah dan biru sebagai alat pencahayaan gambar anaglyph. Dengan efisiensi buck converter yang mencapai hingga 84 persen, proses pengecasan dapat berjalan dengan baik pada tegangan masukan 24 Volt dan keluaran stabil 13,5 Volt. Sensor RGB yang digunakan berhasil membaca berbagai macam warna LED sehingga dapat mengidentifikasi warna dan gambar yang terbaca. Proyek ini berkontribusi pada pengembangan teknologi yang mendukung karya seni anaglyph dan memungkinkan para seniman untuk menampilkan karya mereka tanpa khawatir kehabisan daya pada lampu gambar. This research focuses on developing an efficient battery charging system for red and blue LED lights to support artwork using the anaglyph double exposure technique. Previous studies have discussed the creation of dual-image techniques with anaglyph double exposure and the works of artist Carnovsky RGB, who showcased his art, though it remains relatively unknown to the public. Additionally, earlier research indicates that enhancing critical thinking in children can be supported by appropriate lighting systems. This project aims to design a system using a buck converter for charging batteries for varied lighting with three colors, each with specifications of 12 Volts and 5 Watts. The mains electricity (PLN) will be used to charge a 12.6 Volt 10 Ah battery. The battery charging system employs a buck converter controlled by an STM32F103C8T6 microcontroller, ensuring the battery receives the correct voltage. Power monitoring via Bluetooth enables efficient use of the lights. The primary outcome of this project is the successful development of a battery charging system that maximizes the functionality of red and blue lights as illumination tools for anaglyph images. With a buck converter efficiency of up to 84 percent, the charging process works well at an input voltage of 24 Volts and a stable output of 13.5 Volts. The RGB sensor used successfully reads various LED colors, allowing it to identify colors and images accurately. This project contributes to technological advancements supporting anaglyph art, enabling artists to display their work without worrying about the power supply for their lighting.

Abstract

Penggunaan sepeda motor oleh remaja yang baru memiliki SIM menjadi perhatian serius. Banyak dari mereka mengendarai dengan tingkat emosi tinggi, yang tidak hanya membahayakan diri mereka sendiri tetapi juga orang lain di sekitar mereka. Oleh karena itu, pengawasan ketat dari orang tua sangat diperlukan untuk mencegah kecelakaan. Meskipun sepeda motor pada umumnya aman, risiko kecelakaan meningkat secara signifikan karena kecepatan berlebihan dan penggunaan di jalan raya yang tidak sesuai. Untuk mengatasi masalah ini, penelitian ini mengembangkan sistem monitoring kecepatan dan lokasi sepeda motor menggunakan IoT. Sistem ini bertujuan untuk melacak kecepatan dan lokasi sepeda motor secara real-time, memastikan agar mereka tidak melebihi batas kecepatan aman dan menghindari rute berbahaya. Dengan demikian, orang tua dapat dengan cepat mengetahui posisi anak mereka dan merespons situasi darurat jika diperlukan. Sistem ini menggunakan mikrokontroler STM32F103C8T6, sensor kecepatan, dan sensor lokasi, dengan perangkat Android sebagai antarmuka pengguna. Hasil pengujian menunjukkan bahwa sensor kecepatan yang diuji memiliki akurasi yang baik. Untuk pengukuran kecepatan dalam rpm, pada tachometer 60,4 rpm, speedometer 58,946 rpm dan sensor mencatat 60 rpm dengan kesalahan 0,66% terhadap tachometer dan 1,78% terhadap speedometer. Untuk pengukuran kecepatan dalam km/jam, pada speedometer 5 km/jam dan sensor mencatat 5 km/jam dengan persentase error 0%, pada speedometer 30 km/jam dan sensor mencatat 31 km/jam dengan persentase error 3,3%. Pengujian sensor lokasi juga menunjukkan akurasi yang baik, yang diverifikasi dengan Google Maps. Dalam sistem ini data latitude dan longitude akan terus berubah sesuai pergerakan sepeda motor, untuk tetap memastikan pemantauan posisi secara real-time. The use of motorcycles by newly licensed teenagers is a serious concern due to their often high emotional state, posing risks not only to themselves but also to others. Hence, strict parental supervision is crucial to prevent accidents. While motorcycles are generally safe, the risk of accidents significantly increases due to excessive speed and improper road usage. To address this issue, this study developed an IoT-based system for monitoring motorcycle speed and location. The system aims to track these metrics in real-time, ensuring adherence to safe speed limits and avoiding hazardous routes. This enables parents to quickly locate their children and respond to emergencies promptly. The system utilizes an STM32F103C8T6 microcontroller, speed sensor, and location sensor, with an Android device serving as the user interface. Test results demonstrate the accuracy of the speed sensor: at 60.4 rpm on the tachometer, the speedometer showed 58.946 rpm, while the sensor recorded 60 rpm with a 0.66% error against the tachometer and 1.78% against the speedometer. For speed measurements in km/h, the sensor accurately recorded 5 km/h when the speedometer read 5 km/h (0% error) and 31 km/h when the speedometer read 30 km/h (3.3% error). Location sensor testing confirmed its accuracy, validated by Google Maps. The system continually updates latitude and longitude data based on motorcycle movement, ensuring real-time position monitoring.

Abstract

This work reports an experimental investigation of the effect of blade number on the performance of a small-scale horizontal-axis wind turbine (HAWT) using NACA 4412 airfoil blades. Two turbine prototypes (one with 7 blades and one with 9 blades) were fabricated and tested under controlled wind speeds (3.4–6.0 m/s). The turbine outputs were measured using INA219 current/voltage sensors and a TCRT5000 rotations per minute (RPM) sensor interfaced to an Arduino-based system for real-time data acquisition. Results show that the 9-blade turbine consistently generated higher electrical power and achieved a higher power coefficient than the 7-blade design. For example, at 3.4 m/s the 7-blade turbine produced about 0.0297 W versus 0.0471 W for the 9-blade turbine. The peak power coefficient reached ≈0.198 for the 9-blade rotor (vs. ≈0.195 for 7 blades) at the same wind speed. Sensor calibration indicated high accuracy (errors 1.2%), confirming the reliability of the measurements. These findings suggest that, for the tested design, increasing the number of blades improves small-HAWT performance. The developed wireless monitoring system and experimental results provide guidance for optimizing blade count in future small turbine designs.

Abstract

Dikarenakan kondisi tipografi dan bentuk wilayah yang berupa perbukitan dengan wilayah yang luas, maka di Desa Carang Wulung masih terdapat dusun yang belum ada jaringan listrik tegangan rendah dari PLN yaitu Dusun Gondang. Akibat keterbatasan tersebut, terdapat rumah ibadah (musala) di Dusun Gondang yang masih kurang diperhatikan dan termasuk dalam kategori tidak layak jika dilihat dari sisi ketersediaan listrik. Masyarakat di dusun yang mayoritas beragama Islam ini mengalami kendala penerangan saat shalat berjamaah di malam hari hingga subuh. Tidak adanya sumber listrik untuk pengeras suara juga mengakibatkan tidak dapat digunakannya pengeras suara untuk menandai masuknya waktu sholat. Berdasarkan latar belakang tersebut, maka dikembangkan sistem penyimpanan energi listrik berbasis baterai dengan menggunakan panel surya dalam kegiatan pengabdian masyarakat ini. Tahapan kegiatan pengabdian masyarakat yang dilakukan adalah melakukan survey kebutuhan pemasangan sistem instalasi panel surya dan baterai, perakitan beberapa komponen sistem, melakukan pengujian sistem skala laboratorium, pemasangan sistem yang telah dirakit dan diuji, serta melakukan sosialisasi dan pelatihan kepada warga tentang penggunaan panel surya, pengoperasian dan pemeliharaan sistem. Warga mengaku senang dengan terselenggaranya kegiatan pengabdian masyarakat ini karena dapat beribadah dengan nyaman setiap saat dengan sumber listrik yang tidak mengandalkan sumber dari PLN.

Abstract

Autoped has become a popular alternative in environmentally friendly urban transportation. It uses batteries as the main power source to drive their electric motors. However, efficient and optimal battery usage is essential to maintain the performance and durability of autoped. This study aims to design a speed monitoring system for autoped using LiFePO4 batteries by considering variations in user loads. This monitoring system informs autoped drivers about the speed when used and battery usage. This electric autoped is equipped with a DC brushed motor with a specification of 24 Volt/500 Watt. The speed is measured using a metal proximity sensor that functions without direct contact, thus ensuring consistent measurements and reducing the risk of errors due to physical interaction. In addition, a load cell sensor with a maximum weight measurement of 100 kg is used to classify user's weight which is divided into three variations: 35-45 kg, 46-55 kg, and 56-65 kg. As the main energy source, this system uses a LiFePo4 battery with a specification of 24 Volt/36 Ah. The system was tested on a flat track on the campus, where the scooters were used to support environmentally friendly mobility around the campus area. This test ensured that the designed speed monitoring system was able to provide real-time data on scooter performance based on user weight, as well as support increased efficiency of battery energy use.
