Abstract

Background: Science teaching at the junior high school (SMP) level still struggles to connect scientific concepts with students' everyday experiences. The absence of local wisdom integration contributes to low motivation and poor understanding of scientific material. One underutilized local potential is the traditional drying process of octopus practiced by coastal communities in Kaur Regency, Bengkulu.Aims: This study aims to develop and assess the feasibility of a science learning module based on the local wisdom of dried octopus, focusing on the concepts of temperature, heat, and expansion for seventh-grade students.Method: Using a Research and Development (R&D) approach with the ADDIE model, the study involves five stages: analysis of student and teacher needs, module design, expert-validated development, implementation through a readability test involving 21 seventh-grade students at SMP Negeri 24 Kaur, and final evaluation.Results: The results of the expert validation showed a module feasibility level of 95% with the category "very feasible," while the student readability test obtained an average score of 97% with the category "very easy to understand." The developed module also received positive responses from students regarding engagement, content clarity, language, and usefulness.Conclusion: The science module based on the local wisdom of octopus drying is considered highly feasible and practical for teaching temperature, heat, and expansion. Integrating local wisdom into science learning has been proven to improve students’ cognitive learning outcomes and foster awareness of local cultural values.

Abstract

Pemanfaatan biomassa sebagai sumber energi alternatif merupakan salah satu upaya untuk mengurangi ketergantungan terhadap bahan bakar fosil yang semakin menipis. Salah satu bentuk pemanfaatannya adalah biobriket yang dibuat dari limbah organik melalui proses karbonisasi dan pemadatan. Penelitian ini bertujuan menganalisis kualitas biobriket berbahan limbah kulit kakao (Theobroma cacao L.) dan kulit jeruk (Citrus sinensis) berdasarkan parameter Standar Nasional Indonesia (SNI 01-6235-2000), yaitu kadar air, kadar abu, nilai kalor, dan kerapatan. Biobriket dibuat dengan tiga variasi komposisi, yaitu A1 (63% kulit kakao:27% kulit jeruk), A2 (45%:45%), A3 (27%:63%), serta dua sampel pembanding, C1 (100% kulit kakao) dan C2 (100% kulit jeruk), dengan penambahan perekat 10% pada setiap formulasi. Hasil penelitian menunjukkan bahwa nilai kalor berkisar antara 5272–5482 kkal/kg dan seluruh sampel telah memenuhi standar minimum SNI (>5000 kkal/kg), dengan nilai tertinggi pada C1. Kadar air berkisar 8,93–10,36%, sehingga sebagian sampel masih melampaui batas SNI (<8%). Kadar abu berada pada rentang 7,84–11,53%, dengan hanya C2 yang memenuhi standar. Kerapatan berkisar 1,05–1,21 g/cm³, menunjukkan struktur briket yang cukup padat. Variasi komposisi bahan memengaruhi kualitas biobriket. Limbah kulit kakao dan kulit jeruk berpotensi sebagai bahan baku biobriket, namun optimasi proses masih diperlukan agar seluruh parameter mutu SNI 01-6235-2000 dapat terpenuhi.
