Abstract

The increasing demand for electrical energy poses challenges such as energy waste, which impacts household expenses and the environment. This study aims to design a prototype for monitoring and controlling electrical devices based on the Internet of Things (IoT) using the PZEM-004T sensor. The system is designed to provide real-time electricity consumption information through the Blynk application and allow users to remotely control electrical devices. This prototype utilizes an ESP32 microcontroller and a Solid State Relay (SSR) module for operation and monitoring. The development method used is prototyping, which includes requirement analysis, design, implementation, and testing. Testing was conducted in several households, and the results showed that the PZEM-004T sensor has a high accuracy level, with an average measurement error below 5%. The system provides detailed information on electricity consumption and enables energy savings through more efficient device control. The findings of this study are expected to serve as a practical solution for households to monitor and control electricity usage, support energy efficiency, and reduce electricity costs. Furthermore, this prototype can be further developed for larger-scale applications Keywords: device control, electricity monitoring, PZEM-004T sensor, Internet of Things (IoT)

Abstract

Perkembangan teknologi smartphone yang semakin pesat menyebabkan meningkatnya ketergantungan masyarakat terhadap penggunaan handphone dalam berbagai aktivitas sehari-hari. Tingginya intensitas penggunaan tersebut berdampak pada meningkatnya potensi terjadinya kerusakan, baik pada perangkat keras (hardware) maupun perangkat lunak (software). Permasalahan yang sering dihadapi pengguna adalah keterbatasan pengetahuan dalam mendiagnosis jenis kerusakan handphone, sehingga pengguna harus langsung membawa perangkat ke pusat layanan perbaikan yang memerlukan waktu dan biaya tambahan. Penelitian ini bertujuan untuk mengembangkan aplikasi sistem pakar diagnosis kerusakan handphone berbasis Android dengan menerapkan metode Depth First Search (DFS). Metode DFS digunakan sebagai mekanisme inferensi untuk menelusuri basis pengetahuan yang direpresentasikan dalam bentuk pohon keputusan berdasarkan gejala yang dialami pengguna hingga diperoleh kesimpulan berupa jenis kerusakan serta solusi penanganannya. Pengembangan sistem dilakukan menggunakan model prototyping yang meliputi tahap analisis kebutuhan, perancangan basis pengetahuan, perancangan alur inferensi, implementasi, dan pengujian sistem. Pemodelan sistem menggunakan Unified Modeling Language (UML), dengan bahasa pemrograman PHP menggunakan framework CodeIgniter serta MySQL sebagai basis data. Aplikasi dikembangkan pada platform Android agar mudah diakses oleh pengguna kapan saja dan di mana saja. Hasil pengujian yang dilakukan dengan 15 responden pengguna handphone android dan 3 teknisi hanphone konter Jawa Cell menyatakan bahwa sistem pakar yang dibangun mampu melakukan diagnosis kerusakan handphone secara cepat dan akurat berdasarkan gejala yang diinputkan oleh pengguna. Dengan demikian, sistem ini dapat membantu pengguna memperoleh informasi awal mengenai kerusakan handphone sebelum melakukan perbaikan lebih lanjut, serta menjadi media pembelajaran bagi teknisi pemula dalam proses diagnosis kerusakan handphone secara cepat dan otomatis.

Abstract

This study examines the implementation of a hybrid learning model in limited face-to-face instruction at SMAN 1 Taliwang, developed as an adaptive response to post-pandemic learning conditions. Using a Research and Development (R&D) approach based on the ADDIE model, data were collected through classroom observations, questionnaires for teachers and students, and analysis of pre-test and post-test learning outcomes. The findings indicate that integrating digital tools—such as Google Classroom, video-based materials, and digital modules—helped maintain learning continuity despite reduced classroom hours. Most students reported that digital media facilitated their understanding of the material, although some still faced internet access challenges, particularly those living in peripheral areas of Taliwang. The results show significant improvements in student learning processes and outcomes. The average post-test scores increased compared to the pre-test, and student participation in submitting digital assignments exceeded 85%. Teachers also stated that the hybrid learning model provided greater flexibility in delivering materials and conducting assessments. Although the model did not fully resolve all technical issues and variations in students’ digital literacy, it proved feasible and effective as an adaptive learning strategy at SMAN 1 Taliwang. These findings support the continued refinement and long-term integration of educational technology within the school’s instructional practices.
