Abstract

This research aims to explore the application of the Project-Based Learning (PjBL) model in increasing student creativity at MTs Roudlotur Rosmani, Bengkulu City. The PjBL model provides opportunities for students to learn through hands-on experience in real, relevant projects, which can encourage critical thinking, collaboration and innovation skills. This research used the classroom action research (PTK) method which was carried out in two cycles with the research subjects being class VIII students. The research results show that the application of the PjBL model increases student creativity, as seen in increased active involvement, ability to collaborate, and development of innovative ideas. In the first cycle, although there was an increase in participation, students still depended on teacher guidance in solving problems. However, in the second cycle, students showed significant improvements in innovation and working independently. The main supporting factors in implementing PjBL are teacher readiness, availability of relevant learning media, and school environment support. Obstacles faced include limited time and students' difficulties in working independently. This research suggests the need to improve teachers' skills in designing projects as well as more efficient time management to overcome these obstacles. Overall, PjBL has proven to be effective in increasing student creativity.

Abstract

Abstract: This research aims to determine the potential of grape waste (Vitis vinifera L.) in the production of biogas as an environmentally friendly alternative energy source. The method used in this study was a simple laboratory experiment by utilizing 500 grams of grape waste and 500 mL of clean water with a ratio of 1:1. The mixture was placed into an aquades bottle functioning as a digester, tightly closed using rubber, and connected to a balloon as a gas collector. The fermentation process was carried out anaerobically for six days at room temperature. Daily observations were made on pH changes, odor, and the expansion of the balloon as indicators of gas production. The results showed that the formation of biogas began on the second day and reached its maximum on the fourth day, as indicated by the fully inflated balloon. On the fifth and sixth days, the gas production began to decrease, showing that the fermentation process was nearing completion. It can be concluded that grape waste can be used as raw material for biogas production using simple tools without the addition of other chemical materials. This process is an example of biotechnology application in daily life that supports environmental sustainability and provides a renewable alternative energy source.Keyword: Grape Waste, Biogas, Biotechnology, Renewable Energy, EnvironmentAbstrak: Penelitian ini bertujuan untuk mengetahui potensi limbah buah anggur (Vitis vinifera L.) dalam pembuatan biogas sebagai sumber energi alternatif yang ramah lingkungan. Metode yang digunakan adalah eksperimen laboratorium sederhana dengan memanfaatkan 500 gram limbah buah anggur dan 500 mL air bersih dengan perbandingan 1:1. Campuran tersebut dimasukkan ke dalam botol aquades yang berfungsi sebagai digester, kemudian ditutup rapat menggunakan karet dan dihubungkan dengan balon sebagai penampung gas. Proses fermentasi dilakukan secara anaerob selama enam hari pada suhu ruang. Pengamatan harian dilakukan terhadap perubahan pH, bau, serta pengembangan balon sebagai indikator terbentuknya gas biogas. Hasil penelitian menunjukkan bahwa pembentukan gas mulai terjadi pada hari kedua dan mencapai puncak pada hari keempat yang ditandai dengan balon mengembang secara maksimal. Pada hari kelima dan keenam, volume gas mulai menurun, menandakan bahwa proses fermentasi hampir selesai. Dari hasil ini dapat disimpulkan bahwa limbah buah anggur dapat dimanfaatkan sebagai bahan baku pembuatan biogas dengan menggunakan alat sederhana tanpa tambahan bahan kimia lainnya. Proses ini menjadi contoh penerapan bioteknologi sederhana dalam kehidupan sehari-hari yang mendukung pelestarian lingkungan dan penyediaan energi terbarukan.Kata Kunci: Limbah Buah Anggur, Biogas, Bioteknologi, Energi Terbarukan, Lingkungan
