Abstract

The growing concern over plastic waste pollution and its harmful byproducts, such as CO, CO₂, NOₓ, and SOₓ gases from incineration, necessitates alternative and environmentally responsible waste management strategies. At MAN Insan Cendekia Bengkulu Tengah, a boarding school that manages its own waste, the integration of pyrolysis as a cleaner method for plastic waste treatment offers both practical and educational value. This study aimed to contextualize plastic waste pyrolysis within STEM-based learning to enhance students’ environmental knowledge and attitudes through interdisciplinary instruction. A quasi-experimental two-group pre-test–post-test design was employed, involving 32 students divided equally into control and experimental groups. The control group received STEM instruction using a module and video on plastic pyrolysis, while the experimental group engaged in a more immersive approach involving the same materials supplemented with hands-on pyrolysis activities. Results indicated that the experimental group outperformed the control group, with an environmental knowledge normalized gain (N-gain) score of 0.67 (medium), compared to 0.47 (low) in the control group. Additionally, the experimental group achieved higher environmental attitude scores (85) than the control group (76). These findings demonstrate that STEM education incorporating contextual, multimodal, and practical components can significantly enhance students’ conceptual understanding and engagement with environmental issues. The study contributes to the growing body of evidence supporting experiential STEM education as an effective approach for fostering environmental awareness and action in secondary education settings.

Abstract

This research aims to evaluate the potential of yellow pumpkin peel (Cucurbita moschata) and king banana peel (Musa paradisiaca) as raw materials for bioethanol production, based on the alcohol content produced. The bioethanol production process includes hydrolysis using 5% HCl, fermentation for 7 days with adding nutrients (NPK and urea), and purification through distillation. The research results show that the combination of yellow pumpkin peel and king banana peel, adding NPK, produces the highest ethanol content of 13%. Meanwhile, the lowest content of 4% was obtained from the fermentation of the king banana peel without additional nutrients. The addition of nutrients, particularly NPK, has been proven to enhance the activity of microorganisms in natural fermentation, thereby accelerating the conversion of carbohydrates into ethanol. With the ethanol content produced, the bioethanol from this organic waste can be used practically as E5-type blended fuel without requiring any modifications to vehicle engines. This result shows that fruit peel waste can be an environmentally friendly and economical alternative for renewable energy.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi limbah kepala udang dan daun singkong terhadap pertumbuhan dan kandungan protein maggot Black Soldier Fly (BSF). Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan: P1 (100% kepala udang), P2 (75% kepala udang + 25% daun singkong), P3 (50%+50%), P4 (25% kepala udang + 75% daun singkong), dan P5 (100% daun singkong). Masing-masing perlakuan dengan tiga ulangan. Variabel yang diamati meliputi berat, panjang, ketebalan maggot, konsumsi pakan, laju pertumbuhan spesifik (SGR), indeks pengurangan limbah (WRI), serta kadar protein. Hasil penelitian menunjukkan bahwa secara deskriptif, nilai rata-rata berat maggot berkisar antara 0,04-0,055 g, panjang antara 10,80-11,73 mm, dan laju pertumbuhan spesifik (SGR) antara 6,13-7,23%. Kadar protein maggot tercatat antara 25,09-27,32%, konsumsi pakan berkisar antara 86-93%, dan efisiensi reduksi limbah (WRI) berada pada rentang 5,28-6,64 g/hari. Berdasarkan hasil analisis ragam, seluruh variabel yang diamati tidak menunjukkan perbedaan yang signifikan antar perlakuan (p > 0,05). Dengan demikian, meskipun terdapat variasi nilai secara deskriptif, perbedaan tersebut tidak dapat dianggap nyata secara statistik dan tidak mencerminkan pengaruh perlakuan yang berbeda terhadap pertumbuhan maggot BSF. Penelitian lanjutan perlu dilakukan dengan jumlah sampel yang lebih besar, serta analisis kandungan nutrisi pakan yang lebih rinci, guna memperoleh hasil yang lebih akurat dan aplikatif. ABSTRACT This study aims to investigate the effect of combining shrimp head waste and cassava leaves on the growth and protein content of Black Soldier Fly (BSF) maggots. The study used a Completely Randomized Design (CRD) with five treatments: P1 (100% shrimp heads), P2 (75% shrimp heads + 25% cassava leaves), P3 (50% + 50%), P4 (25% shrimp heads + 75% cassava leaves), and P5 (100% cassava leaves). Each treatment had three replications. The observed variables included weight, length, thickness of maggots, feed consumption, specific growth rate (SGR), waste reduction index (WRI), and protein content. The results of the study showed that descriptively, the average maggot weight ranged from 0.04-0.055 g, length between 10.80-11.73 mm, and specific growth rate (SGR) between 6.13-7.23%. Maggot protein content was recorded between 25.09-27.32%, feed consumption ranged from 86-93%, and waste reduction efficiency (WRI) was in the range of 5.28-6.64 g/day. Based on the results of the analysis of variance, all observed variables did not show significant differences between treatments (p > 0.05). Thus, although there were variations in descriptive values, these differences cannot be considered statistically significant and do not reflect the effect of different treatments on the growth of BSF maggots. Further research is needed with a larger sample size, as well as a more detailed analysis of feed nutrient content, to obtain more accurate and applicable results.
