Abstract

Coconut shell is a biomass waste that is abundantly generated from household activities, traditional markets, and coconut-based food industries. However, its utilization remains limited, and open burning is still commonly practiced, causing environmental pollution and health problems. This study aimed to design and implement a manual coconut shell briquette-making device as an appropriate technology for household and small-scale business applications. The study employed a limited-scale field trial combined with a participatory community approach in Sukasari Village, Serang Baru District, Bekasi Regency. The device consisted of a manual meat grinder, steel frame, PVC pipe, wooden board, and recycled can. Operational testing showed that the device was capable of producing approximately 15–20 kg of briquettes per day. The briquettes exhibited satisfactory physical characteristics, including adequate strength, low smoke emissions, and a burning duration of 45–60 minutes. The implementation received positive responses from the local community and demonstrated potential environmental and economic benefits through biomass waste utilization and alternative energy production.

Abstract

Water pollution by heavy metals such as lead (Pb), cadmium (Cd), and chromium (Cr) is a serious environmental problem, particularly in industrial areas such as Bekasi, West Java. Heavy metals are toxic, non-biodegradable, and bioaccumulate in food chains, posing serious risks to human health and ecosystems. This study aimed to evaluate the effectiveness of rice husk and coconut shell-based biochar as alternative filter media through a systematic literature review of scientific articles published between 2021 and 2026, indexed in Scopus, Web of Science, and Google Scholar. The results indicate that coconut shell biochar produced at a pyrolysis temperature of 550°C achieves a BET surface area of 387 m²/g and removal efficiencies of 93.8% for Pb(II), 88.5% for Cd(II), and 81.2% for Cr(VI). The adsorption mechanism is multimechanistic, involving ion exchange, surface complexation, precipitation, and physical adsorption, with kinetics best described by the pseudo-second-order model (R² ≥ 0.99). Feasibility analysis demonstrates that a household-scale biochar filter unit can be produced for IDR 149,000–300,000 and can treat 50–100 liters of water per day with a service life of 3–6 months. Iron-modified biochar innovations improve heavy metal removal efficiency by 25–45% compared to conventional biochar. This technology is deemed technically, economically, and environmentally feasible as an appropriate technology solution for water treatment in low-income communities

Abstract

The rapid development of technology, particularly Artificial Intelligence (AI), has significantly influenced educational practices, including English language learning. This study aimed to investigate the implementation of Artificial Intelligence in English language learning and explore eighth-grade students’ perceptions toward the use of AI at SMPK 1 Harapan Denpasar. This study employed a descriptive qualitative research design involving 36 eighth-grade students, with seven students selected as interview participants through convenience sampling techniques. Data were collected through observation, questionnaires, interviews, and document analysis. The collected data were analyzed using the interactive model proposed by Miles et al., including data reduction, data display, and drawing conclusions. The findings revealed that AI had been successfully integrated into English learning activities and contributed positively to classroom learning processes. The implementation of AI created a more interactive learning environment and increased students’ enthusiasm and engagement during learning activities. Furthermore, students demonstrated highly positive perceptions regarding the use of AI based on the Technology Acceptance Model (TAM) indicators, namely perceived usefulness and perceived ease of use. Students perceived AI as beneficial in supporting vocabulary development, grammar improvement, pronunciation practice, and assignment completion. AI was also considered easy to use because it provided quick responses and accessible features that encouraged independent learning. Although students recognized certain limitations such as inaccurate responses and system errors, they demonstrated critical awareness by evaluating and verifying AI-generated information. Therefore, the findings suggest that Artificial Intelligence has considerable potential to support and improve the effectiveness of English language learning.

Abstract

This study aims to analyze the rate of deforestation in Papua and its ecological implications, using the documentary film "Pesta Babi" as a medium for ecological representation and critique. Massive deforestation in Papua, primarily due to food estate projects, oil palm plantation expansion, and mining, has threatened the food and energy sovereignty of indigenous communities. A qualitative approach using media text analysis and a systematic literature review was used in this study. The analysis shows that the forced conversion of indigenous forests not only eliminates traditional biomass-based food and energy sources but also marginalizes local communities, triggers biodiversity loss, and contributes to the global climate crisis. In conclusion, a review of forest management policies that position local communities as rights-holders is needed to reduce the rate of deforestation, protect the food and energy sovereignty of indigenous communities, and prevent natural colonialism.

Abstract

Peningkatan jumlah penduduk berbanding lurus dengan peningkatan jumlah limbah yang dihasilkan dari aktifitas manusia, dan salah satu limbah yang dihasilkan serta berpengaruh langsung terhadap kualitas lingkungan adalah limbah cair domestic dari aktifitas rumah tangga. Upaya pengelolaan limbah cair domestik rumah secara tepat sangat diperlukan untuk menanggulangi dampak pencemaran dan kerusakan lingkungan yang terjadi. Pemerintah Daerah Istimewa Yogyakarta sejak tahun 1994 sudah mempunyai pengolahan limbah cair domestik terpusat skala regional. Salah satu pengolahan limbah cair domestik yang ada di Daerah Istimewa Yogyakarta adalah Balai Pialam Yogyakarta. Tingginya pertumbuhan penduduk di Yogyakarta dapat berdampak pada penurunan kualitas lingkungan, salah satunya terjadi pencemaran air, oleh karena itu perlu dilakukan studi terkait kualitas air yang dihasilkan dari proses pengolahan IPAL di Balai Pialam Yogyakarta sehingga dapat dipastikan air yang dibuang ke badan air aman serta tidak mencemari lingkungan dan biota air. Sosialisasi yang dilakukan berupa perlu adanya penanganan khusus terhadap kualitas air outlet IPAL untuk parameter yang tidak memenuhi baku mutu seperti DO, BOD, COD dan TSS dan diperlukan adanya kajian mengenai kualitas air dari hulu (upstream) dan hilir (downstream) dari badan sungai (Sungai Bedog) untuk mengevaluasi kualitas air berdasarkan status mutu airnya.

Abstract

Mangrove ecosystems function as critical coastal buffer systems that provide ecological, physical, and socio-economic benefits. However, increasing anthropogenic pressures have accelerated mangrove degradation, particularly in vulnerable coastal regions such as Muara Gembong, Bekasi. This study aims to analyze the ecological functions of mangroves, identify the drivers and dynamics of degradation, and assess their implications for coastal vulnerability using a qualitative Systematic Literature Review (SLR) based on the PRISMA framework. A total of 1,860 records were initially identified, with 160 studies selected for final synthesis after a rigorous screening process. The results indicate that mangroves play a crucial role in supporting biodiversity, regulating nutrient cycles, storing blue carbon, and attenuating wave energy while stabilizing shorelines. However, these functions have significantly declined due to land-use conversion, particularly for aquaculture, along with socio-economic pressures and environmental dynamics. This degradation has increased coastal vulnerability, manifested in erosion, tidal flooding, and reduced community resilience. This study demonstrates that mangrove degradation is a multidimensional socio-ecological process and proposes an integrated analytical framework linking ecological functions,  degradation dynamics, and coastal vulnerability. This framework provides a conceptual foundation for strengthening sustainable coastal management strategies in tropical regions.
