Abstract

Pengembangan masyarakat masih dibutuhkan dalam rangka mengembangkan masyarakat secara berkelanjutan. Namun, dalam pelaksanaannya tidaklah mudah karena ada beberapa langkah yang harus dilakukan dan harus melibatkan banyak pihak. Agar suatu program pemberdayaan dapat berjalan efektif dan sesuai dengan kebutuhan masyarakat, maka perlunya dilakukan investigasi terlebih dahulu sebelum merencanakan program. Salah satu investigasi yang dapat dilakukan adalah dengan menggunakan teknik social mapping. Penelitian ini bertujuan untuk mengidentifikasi berbagai potensi dan permasalahan sosial yang ada di Dusun Pamubutan. Dalam penelitian ini akan membahas mulai dari profil Dusun Pamubutan, analisis peran kelompok desa, identifikasi masalah sosial, masalah sosial potensial, hingga identifikasi potensi sosial yang ada di Dusun Pamubutan. Metode yang digunakan dalam penelitian ini yakni metode kualitatif dengan melakukan observasi, wawancara, dan studi dokumentasi guna mendapatkan hasil penelitian yang mendalam serta menyeluruh. Berbagai masalah sosial yang terjadi di Dusun Pamubutan diantaranya yaitu konflik air, konflik nilai dengan pengepul, dan masalah struktural kelembagaan. Berdasarkan permasalahan tersebut, maka teridentifikasilah potensi modal sosial dengan melihat unsur trust, networking, norma, nilai dan hubungan timbal balik (resiprocal).

Abstract

Kemampuan berpikir kritis yang dimiliki siswa tergolong rendah, hal ini juga berdampak pada hasil belajar siswa. Oleh karena itu, penelitian ini bertujuan untuk mengetahui pengaruh model PBL berbantuan authetic video terhadap kemampuan berpikir kritis dan hasil belajar siswa pada materi getaran dan gelombang. Penelitian dilakukan pada kelas kontrol dan kelas eksperimen, dengan desain penelitian posttest only control group. Data primer diperoleh melalui tes yang dilakukan di akhir kegiatan pembelajaran (posttest), data hasil tes akan dianalisis dengan uji normalitas dan uji t dengan taraf signifikansi 5%. Hasil penelitian berpikir kritis kedua kelas menunjukkan 0,000 < 0,05 yang artinya H0 ditolak dan Ha diterima, sehingga kedua kelas memiliki perbedaan nilai yang signifikan. Sementara hasil belajar dengan ketentuan taraf signifikansi yang sama memiliki hasil sebesar 0,011<0,05 yang artinya hasil belajar kedua kelas berbeda secara signifikan. Dengan demikian, dapat disimpulkan bahwa penggunaan model PBL berbantuan authentic video berpengaruh terhadap kemampuan berpikir dan hasil belajar siswa pada materi getaran dan gelombang.

Abstract

Methyl orange dye is an organic pollutant often found in textile industry waste and harms the environment due to its nature, which makes it difficult to decompose naturally. One method that has attracted attention in its processing is the Photo-Fenton process, which utilizes hydroxyl radicals (•OH) as powerful degradation agents. This article summarizes recent developments in applying heterogeneous Photo-Fenton to Methyl Orange degradation, focusing on degradation efficiency, factors influencing reactions, and degradation pathways. This study discusses the influence of reaction parameters such as initial pH, H₂O₂ concentration, catalyst concentration and light intensity on the degradation rate. In addition, various types of heterogeneous catalysts, including metal oxide-based and ferrous composites, were analyzed based on their effectiveness and stability in the Photo-Fenton system. The Methyl Orange degradation pathway is proposed based on an intermediate product identified in previous studies, suggesting that the reaction proceeds through a gradual oxidation mechanism until simpler and more environmentally friendly compounds are formed. The results of this study show that the heterogeneous Photo-Fenton system provides advantages over homogeneous systems, especially in increasing degradation efficiency and prolonging the catalyst reactivity cycle. The use of heterogeneous catalysts allows for the formation of larger numbers of active species, thus accelerating the breaking of the Methyl Orange structure. In addition, further research is needed to improve the stability of the catalyst, optimize reaction conditions, and evaluate its potential application on an industrial scale. This study will be a reference for developing a more efficient and sustainable Photo-Fenton-based waste treatment method.

Abstract

Nagari Ketaping in Batang Anai District has great potential for culinary tourism, especially through traditional fried snack vendors such as sala lauak. However, the extensive use of cooking oil in these activities leads to the generation of used cooking oil (jelantah), which poses serious health and environmental risks. Repeated use of the oil produces free radicals and carcinogenic substances that may cause degenerative diseases, while improper disposal into waterways leads to pollution and ecosystem damage. This community service program aims to educate and raise awareness among members of the majlis taklim in Nagari Ketaping about the dangers of used cooking oil and to demonstrate its potential for conversion into economically valuable products. The main participants are housewives who also operate small fried snack businesses. The outcomes include a scientific publication in Pelita Eksakta Journal (FMIPA UNP), a video documentation, and online media dissemination through Berita Minang.
