Abstract

Pembelajaran Fisika yang di terapkan di SMA Warga Surakarta belum mengarahkan siswa pada pembelajaran berbasis keterampilan proses dan cenderung teacher centered. Penelitian ini bertujuan untuk merancang dan menyusun modul elektronik pembelajaran Fisika berbasis keterampilan proses sains, serta menguji efektivitas modul terhadap kemampuan berpikir kritis dan motivasi belajar siswa.  Metode penelitian dan pengembangan yang digunakan Research and Development (R&D). Model penelitian dan pengembangan menggunakan model penelitian 4D Thiagarajan. Modul Fisika dikembangkan menggunakan pendekatan keterampilan proses sains dengan langkah: mengamati, merumuskan masalah, merumuskan hipotesis, mengidentifikasi variabel, melakukan eksperimen, menganalisis data, menyimpulkan dan mengomunikasikan. Instrumen yang digunakan dalam penelitian ini adalah angket, lembar validasi, lembar observasi dan soal pretest&post test. Analisis hasil angket, kelayakan modul dan hasil observasi dianalisis dengan diskriptif kualitatif berdasarkan skor kriteria. Analisis kemampuan berpikir kritis diuji dengan program SPSS dengan uji parametrik sampel berpasangan, sedangkan motivasi belajar dianalisis menggunakan uji non parametrik Mann Whitney. Hasil penelitian menunjukkan bahwa: 1) modul elektronik telah dikembangkan dengan mengintegrasikan keterampilan proses sains untuk meningkatkan kemampuan berpikir kritis dan motivasi belajar siswa. 2) Modul elektronik Fisika berbasis keterampilan proses sains memenuhi kriteria sangat baik, dilihat dari hasil validasi materi, media, validasi praktisi pendidikan dan teman sejawat, dengan nilai rata-rata 3,80 lebih besar dari nilai minimum kelayakan 3,78. 3) efektivitas modul berbasis keterampilan proses sains didapatkan nilai N-gain dari uji coba besar  0,67 pada kelas sampel dan 0,59 pada kelas kontrol yang dikategorikan ˝sedang˝. 4) Implementasi modul elektronik Fisika berbasis keterampilan proses sains ini dinilai efektif meningkatkan motivasi belajar siswa. Hasil uji statistik menunjukkan nilai signifikansi sebesar 0,027 lebih rendah dari taraf signifikansi α =0,05, hal ini berarti bahwa terdapat perbedaan yang signifikan antara motivasi belajar kelas sampel dan kelas kontrol. Sehingga dapat disimpulkan bahwa motivasi belajar siswa menggunakan modul Fisika berbasis keterampilan proses sains lebih baik dari pembelajaran konvensional

Abstract

This study investigates the development and implementation of a dual-axis solar tracking system for off-grid 100Wp photovoltaic (PV) systems to enhance energy harvesting efficiency and ensure sustainable power generation. The research addresses the limitations of fixed-tilt PV systems, which often underperform due to suboptimal solar alignment, especially in regions with dynamic weather conditions. The results demonstrated a significant increase in energy output, achieving up to 13,75% higher efficiency compared to static systems under similar operational conditions. This improvement is attributed to the system's ability to maintain optimal solar panel orientation throughout the day, facilitated by an advanced tracking algorithm and real-time sensor integration. The distinctive features of the developed system include its cost-effective design, adaptability to various geographical locations, and robust performance under fluctuating environmental conditions. The findings suggest that the dual-axis tracking system is wellsuited for deployment in remote or off-grid areas where reliable and efficient power generation is critical. Practical applications of this system are particularly relevant for rural electrification, agricultural irrigation systems, and other decentralized energy solutions in regions with abundant solar resources.

Abstract

Sumberingin Bath is one of the natural tourist destinations located in Wringinsongo Village, Tumpang District, Malang Regency, East Java. This bathing site features a clear and refreshing spring, attracting many visitors from various regions. However, Sumberingin Bath has tourism potential that has not been fully optimized, particularly in the area of night tourism. The objective of this community service project is to develop a decorative lighting area powered by renewable energy at Sumberingin Bath. The methodology employed includes the development of decorative lighting infrastructure, providing training to the community on the management, maintenance, and installation of lights integrated with a solar power system, and creating a selfie tourism program that leverages the beauty of decorative lights to enhance the destination's appeal on social media. The results of this community service initiative offer solutions to the issue of limited lighting and the need to extend the operational hours of the tourist site, while also increasing knowledge and adding value to the location as a renewable energy-based night tourism destination. A total of more than 40 decorative lights were installed, with an average power consumption of 1,200 watts. The energy for these lights is derived from renewable energy stored in a powerwall system with a capacity of 14,400 watts
