Abstract

Rapid technological advancement and the demands of Industry 4.0 and Society 5.0 require vocational high school teachers to effectively integrate technology, pedagogy, and content knowledge. However, the implementation of Technological Pedagogical Content Knowledge (TPACK) among vocational teachers in Indonesia remains constrained, particularly due to disparities in institutional support between public and private schools. This study aims to examine the level of TPACK competence among vocational high school teachers and to compare TPACK profiles between public and private institutions. A descriptive quantitative approach was employed involving 62 teachers from eight public and private vocational high schools in Bali and North Sulawesi provinces. Data were collected through Likert-scale questionnaires and interviews, and analyzed using descriptive statistics, multiple linear regression, and independent-samples t-tests. The findings indicate that teachers’ overall TPACK competence falls within a moderate category. Regression analysis reveals that Technological Knowledge (TK) and Content Knowledge (CK) have significant effects on TPACK, while other components do not show partial significance. In addition, a significant difference was found between public and private vocational schools, with teachers in public schools demonstrating higher TPACK competence. This study concludes that sustained professional development and stronger institutional support are essential to enhance vocational teachers’ capacity to integrate technology effectively, particularly in private schools. These findings provide empirical evidence to inform policy and targeted interventions for strengthening TPACK in vocational education contexts.

Abstract

The advancement of Internet of Things (IoT) technology has spurred the development of smart home systems that enhance security, comfort, and energy efficiency in residential environments. This study aims to design and develop a smart home prototype based on the ESP32 microcontroller, implemented within the context of Citraland Manado housing. The system integrates multiple sensors, including PIR for motion detection, DHT22 for temperature and humidity monitoring, and MQ-2 for hazardous gas detection, with actuators such as relays, solenoid locks, and buzzers. Data communication between devices and users is facilitated via the MQTT protocol using the HiveMQ Cloud broker, while the user interface is developed as a web-based Progressive Web App (PWA) accessible in real time from both mobile and desktop devices. The research employs a Research and Development (R&D) methodology with an iterative system development approach. Testing results demonstrate that all components function as designed, data communication remains stable with latency under one second, and the PWA interface is responsive and user-friendly. Nevertheless, the system still faces limitations regarding push notifications and long-term data storage. Overall, this prototype proves to be a viable, affordable, and self-reliant smart home solution with potential for further development and real-world implementation. ABSTRAK Perkembangan teknologi Internet of Things (IoT) mendorong hadirnya sistem smarthome yang mampu meningkatkan keamanan, kenyamanan, dan efisiensi energi di lingkungan perumahan. Penelitian ini bertujuan merancang dan mengembangkan prototipe sistem smarthome berbasis mikrokontroler ESP32 yang diimplementasikan dalam konteks Perumahan Citraland Manado. Sistem ini mengintegrasikan berbagai sensor, seperti PIR untuk deteksi gerakan, DHT22 untuk pemantauan suhu dan kelembapan, serta MQ-2 untuk deteksi gas berbahaya, dengan aktuator seperti relay, solenoid lock, dan buzzer. Komunikasi data antara perangkat dan pengguna dilakukan melalui protokol MQTT dengan broker HiveMQ Cloud, sedangkan antarmuka pengguna dibangun sebagai Progressive Web App (PWA) berbasis web yang dapat diakses secara real-time dari perangkat mobile maupun desktop. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan pendekatan pengembangan sistem secara iteratif. Hasil pengujian menunjukkan bahwa seluruh komponen berfungsi sesuai rancangan, komunikasi data berjalan stabil dengan latensi di bawah 1 detik, dan antarmuka PWA responsif serta mudah digunakan. Meski demikian, sistem masih memiliki keterbatasan dalam hal notifikasi push dan penyimpanan data jangka panjang. Secara keseluruhan, prototipe ini terbukti layak sebagai solusi smarthome yang terjangkau, mandiri, dan dapat dikembangkan lebih lanjut untuk implementasi skala nyata.

Abstract

Abstrak: Usaha budidaya ikan keramba jaring tancap di Desa Passo menghadapi kendala keterbatasan energi dan tingginya biaya operasional. Program pengabdian ini bertujuan menerapkan microgrid panel surya terintegrasi penyimpanan energi untuk meningkatkan kemandirian energi dan produktivitas budidaya ikan. Metode meliputi penyuluhan, instalasi microgrid, pelatihan, penyusunan SOP, penerapan pakan otomatis berbasis energi surya, serta pelatihan manajemen usaha. Kegiatan diikuti 23 peserta dan dievaluasi melalui pre-test, post-test, serta observasi keterampilan dan implementasi teknologi. Hasil menunjukkan peningkatan pengetahuan dengan N-Gain 0,66 (kategori sedang). Sistem yang dibangun memiliki kapasitas 400 Wp, penyimpanan energi 1,2 kWh, dan keluaran 3 kW, serta mampu menggantikan penggunaan genset. Selain itu, 91,3% peserta mampu melakukan pencatatan biaya produksi dan pendapatan. Penerapan microgrid panel surya terbukti meningkatkan kemandirian energi, efisiensi operasional, dan keberlanjutan usaha budidaya ikan.Abstract: The fixed net cage fish farming business in Passo Village faces constraints of limited energy and high operational costs. This community service program aims to implement a solar panel microgrid integrated with energy storage to increase energy independence and fish farming productivity. Methods include counseling, microgrid installation, training, SOP development, implementation of solar energy-based automatic feed, and business management training. The activity was attended by 23 participants and evaluated through pre-tests, post-tests, and observations of skills and technology implementation. The results showed an increase in knowledge with an N-Gain of 0.66 (moderate category). The system built has a capacity of 400 Wp, 1.2 kWh of energy storage, and 3 kW of output, and is able to replace the use of generators. In addition, 91.3% of participants were able to record production costs and income. The implementation of solar panel microgrids has been proven to increase energy independence, operational efficiency, and sustainability of fish farming businesses.
