Abstract

ABSTRACT This study aimed to analyze the characteristics of charcoal briquettes produced from cashew nut shell waste (Anacardium occidentale) using Cashew Nut Shell Liquid (CNSL) as a binder. The research was conducted experimentally using three binder compositions: A (25 g charcoal : 15 mL CNSL), B (25 g charcoal : 20 mL CNSL), and C (25 g charcoal : 25 mL CNSL), with each treatment replicated three times. Cashew nut shells were carbonized through a pyrolysis process, mixed with CNSL binder, and molded into briquettes. The briquettes were characterized based on moisture content, ash content, volatile matter, fixed carbon, calorific value, density, and burning rate. The results showed that increasing the amount of CNSL binder increased moisture content, ash content, volatile matter, and density, while decreasing fixed carbon and calorific value. The moisture content values were 9.21%, 9.62%, and 13.07%, respectively; ash content was 4.31%, 6.40%, and 7.23%; volatile matter ranged from 15.36% to 21.89%; and fixed carbon decreased from 70.71% to 57.81%. The highest calorific value was obtained in treatment A, reaching 5,928 cal/g. Based on the overall parameters evaluated, treatment A produced the best briquette characteristics. The findings indicate that CNSL has potential as a binder for biomass briquettes; however, several parameters, particularly moisture content, volatile matter, and calorific value in some treatments, did not fully comply with the requirements of SNI 01-6235-2000. ABSTRAK Penelitian ini bertujuan untuk menganalisis karakteristik briket arang dari limbah kulit biji jambu mete (Anacardium occidentale) dengan menggunakan perekat Cashew Nut Shell Liquid (CNSL). Penelitian dilakukan secara eksperimental menggunakan tiga variasi komposisi perekat, yaitu A (25 g arang : 15 mL CNSL), B (25 g arang : 20 mL CNSL), dan C (25 g arang : 25 mL CNSL), dengan masing-masing perlakuan dilakukan tiga kali ulangan. Kulit biji jambu mete dikarbonisasi melalui metode pirolisis, kemudian dicampur dengan perekat CNSL dan dicetak menjadi briket. Karakteristik yang diuji meliputi kadar air, kadar abu, kadar zat terbang, kadar karbon terikat, nilai kalor, kerapatan, dan laju pembakaran. Hasil penelitian menunjukkan bahwa peningkatan jumlah perekat CNSL meningkatkan kadar air, kadar abu, kadar zat terbang, dan kerapatan briket, tetapi menurunkan kadar karbon terikat dan nilai kalor. Nilai kadar air berturut-turut sebesar 9,21%; 9,62%; dan 13,07%, kadar abu 4,31%; 6,40%; dan 7,23%, kadar zat terbang 15,36%–21,89%, serta kadar karbon terikat 70,71%–57,81%. Nilai kalor tertinggi diperoleh pada perlakuan A sebesar 5.928 kal/g. Berdasarkan keseluruhan parameter, perlakuan A menghasilkan karakteristik briket terbaik. CNSL berpotensi digunakan sebagai perekat briket biomassa, meskipun beberapa parameter, terutama kadar air, kadar zat terbang, dan nilai kalor pada beberapa perlakuan, belum sepenuhnya memenuhi standar SNI 01-6235-2000.

Abstract

An interesting aspect of this study is that chemistry education students were able to complete project assignments involving the production of Virgin Coconut Oil (VCO), VCO soap, and VCO-ginger shampoo, even though they had never previously encountered real-world problems that needed to be solved through Project-Based Learning. The purpose of this research was to identify the learning strategies applied by chemistry education students in completing project assignments in the Technology of Chemistry Handicraft course. This research employed a descriptive survey method involving 45 students enrolled in the course during the 2024/2025 academic year. Data were collected through questionnaires and interviews, referring to the Self-Regulated Learning (SRL) framework, and analyzed using quantitative descriptive techniques. The results revealed that students’ learning strategies based on Self-Regulated Learning were categorized as very high, with an average score of 87.4% across three main dimensions. In the planning stage, students demonstrated the ability to design tasks, manage time, and divide roles within groups, achieving an average score of 89.6%. The implementation stage indicated strong collaboration skills and the effective use of technology, with a score of 86.5%. The evaluation stage, which included reflection and revision of project outcomes, reached 86%. Overall, students demonstrated the ability to plan their work, collaborate in groups, utilize technology, and reflect on their project outcomes, such as the production of VCO, VCO soap, and VCO-ginger shampoo. These findings indicate that Self-Regulated Learning skills help students become more independent, focused, and effective in completing project-based assignments. ABSTRAKHal yang menarik dalam penelitian ini adalah mahasiswa pendidikan kimia dapat menyelesaikan tugas proyek pembuatan Virgin Coconut Oil (VCO), Sabun VCO dan Shampo VCO-jahe tetapi dalam perkuiahan maupun di laboratorium mereka belum pernah dihadapkan pada masalah nyata yang harus di pecahkan melalui pembelajaran berbasis proyek. Tujuan penelitian ini adalah untuk mengidentifikasi strategi belajar yang diterapkan mahasiswa Pendidikan Kimia dalam menyelesaikan tugas proyek pada mata kuliah Teknologi Prakarya Kimia. Penelitian ini merupakan survei deskriptif dengan melibatkan 45 mahasiswa yang memprogram mata kuliah Teknologi Prakarya kimia tahun 2024/2025. Data dikumpulkan menggunakan kuesioner dan wawancara dengan mengacu pada strategi belajar Self-Regulated Learning. Data dianalisis menggunakan teknik deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa strategi belajar mahasiswa menggunakan Self-Regulated Learning termasuk dalam kategori sangat tinggi dengan rata-rata 87,4% pada ketiga dimensi. Pada tahap perencanaan, mahasiswa mampu merencanakan tugas, mengatur waktu, serta melakukan pembagian peran dalam kelompok dengan rata-rata 89,6%. Tahap pelaksanaan menunjukkan kemampuan kolaborasi dan pemanfaatan teknologi sebesar 86,5%. Tahap evaluasi meliputi kegiatan refleksi dan revisi hasil proyek dengan capaian 86%. Mahasiswa mampu merencanakan pekerjaan, bekerja sama dalam kelompok, memanfaatkan teknologi, serta melakukan refleksi terhadap hasil proyek seperti pembuatan Virgin Coconut Oil (VCO), sabun VCO dan sampo VCO-jahe. Hasil ini menunjukkan bahwa kemampuan regulasi diri dalam belajar membantu mahasiswa menjadi lebih mandiri, terarah, dan efektif dalam menyelesaikan tugas proyek.
