Abstract

Waste is a very complex and urgent problem to be solved. The problems occur due to the participation of the residents as the leading actor. This study aimed to determine the significance of the influence of gender, age, education, employment status, income, duration of stay, and the level of knowledge on waste generation and management. Respondents to questionnaires and interviews were 37 people whose numbers were determined based on the Slovin equation, while data was analyzed using SPSS Statistics 20 software. A person's educational status significantly positively affects people's habits in reducing waste generation. The following positive significance was income, gender, and length of stay. Age and employment status have a negative correlation, indicating that the older and working, the less waste the society generates. Besides affecting waste generation, it turned out that education also significantly affects waste management. Therefore, education is the main factor considered in waste planning. The results of this study can be used as input for the Indonesian Government in providing information through training and the provision of waste management facilities.

Abstract

Data SIPSN tiga tahun terakhir menunjukkan timbulan sampah di Kabupaten Langkat meningkat 24,71% atau dari yang awalnya 152.099 menjadi 189.685 ton. Lebih dari 42% timbulan sampah disumbangkan oleh sektor domestik yang seharusnya dapat dikelola sedekat mungkin dari sumbernya. Dengan demikian, kegiatan pengabdian kepada masyarakat ini bertujuan memberikan pelatihan agar masyarakat lebih memahami cara mengurangi timbulan sampah dengan mengubahnya menjadi produk yang bermanfaat. Pelatihan dilaksanakan pada 5 Agustus 2021 di Rumah Komunitas Pohon Rindang, Desa Perkebunan Bukit Lawang, kepada 43 anak usia 8-15 tahun. Metode yang digunakan adalah penyuluhan interaktif dengan memberikan demonstrasi cara membuat keranjang takakura dan stringbag. Keranjang takakura 45x37x57 cm dapat menampung hingga 1,5 kg sampah organik basah per hari, sedangkan pembuatan pakaian bekas menjadi stringbag dapat menunda pembuangan material ke TPA. Dalam jangka panjang kegiatan ini diharapkan menjadi kebiasaan baru bagi masyarakat dalam mengelola sampah untuk menjadikan Desa Perkebunan Bukit Lawang sebagai desa pariwisata yang berkelanjutan.

Abstract

Domestic wastewater treatment often faces challenges due to high concentrations of organic matter and dissolved solids that can pollute the environment if left untreated. This study aims to evaluate the performance of a honeycomb biofilter in reducing key wastewater pollutants. The method applied was a laboratory-scale experiment using a small-scale WWTP system equipped with a honeycomb biofilter unit. The treatment results showed a significant reduction of BOD from 56 mg/L to 4.15 mg/L (92% efficiency), COD from 224 mg/L to 5 mg/L (97% efficiency), and TDS from 290 mg/L to 194 mg/L (30% efficiency). All parameters meet the quality standards. However, pH decreased from 7.4 to 4.4 (40% reduction), indicating the need for a pH adjustment unit before final discharge. In conclusion, the honeycomb biofilter proved effective in reducing organic load and dissolved solids, although integration with a pH neutralization unit is required to comply with environmental standards.

Abstract

This study aimed to detect mangrove cover, analyze spatio-temporal changes, and assess mangrove health conditions in South Banawa District, Donggala Regency, using multi-temporal Sentinel-2A imagery. Mangrove detection was conducted using a machine learning based Decision Tree algorithm, while mangrove health was evaluated using the Mangrove Health Index (MHI). The variables included spectral bands and multiple spectral indices (NDVI, NDBI, MNDWI, CMRI, NBR, GCI, SIPI, and ARVI). The classification model demonstrated very high performance, with Overall Accuracy, Kappa, and F1-Score values exceeding 98%. The results indicated a decline in mangrove area from 123.96 ha to 95.5 ha, equivalent to a loss of 28.46 ha (22.96%) during the observation period. Degradation was spatially concentrated in areas with high accessibility and proximity to shrimp farming activities. Despite this decline, mangrove conditions were predominantly classified as healthy (87.56%), followed by moderate (12.41%) and poor (0.03%) categories. MHI-based mitigation strategies prioritize low-index areas for restoration through hydrological rehabilitation and buffer zone establishment, while healthy areas are primarily focused on conservation and periodic monitoring. This approach supports data-driven conservation planning, restoration prioritization, and sustainable coastal management based on remote sensing and machine learning.

Abstract

This study aims to analyze the strategies employed by Amil Zakat Institutions (LAZ) in Southeast Sulawesi to enhance zakat collection using the Business Model Canvas integrated with the Social Enterprise Model Canvas approach. A descriptive qualitative method was applied, focusing on two institutions: Baitul Maal Hidayatullah (BMH) and Wahdah Inspirasi Zakat (WIZ). Data were collected through observation, in-depth interviews, and document analysis. The results reveal that strategic collaboration with public institutions, such as Baznas and the Ministry of Religious Affairs, as well as partnerships with private companies like PLN and Telkomsel, significantly improve zakat collection performance. Additionally, diversification of funding channels and the adoption of digital technology expand outreach, enhance transparency, and strengthen accountability in zakat management. This study is limited to two LAZ institutions in Southeast Sulawesi, which may restrict generalizability. However, the findings provide practical insights for zakat institutions in developing collaborative networks and leveraging digital innovation to improve performance. This research offers a novel integration of the Business Model Canvas and Social Enterprise Model Canvas in the context of zakat management, highlighting the importance of cross-sector collaboration and digital transformation to increase efficiency, transparency, and public trust in zakat institutions.

Abstract

Climate change is a global issue and challenge that may have impacts in the future, thus requiring the strengthening of environmental literacy and awareness, particularly among the younger generation. This community service activity was aimed at new students of the Faculty of Forestry, Tadulako University, as educational partners in fostering an understanding of global climate change mitigation. The activity aimed to enhance participants’ knowledge, awareness, and commitment to the importance of climate change mitigation actions. The intervention was carried out through a public lecture featuring a speaker from the Green Institute, which included material presentation, interactive discussions, question-and-answer sessions, and reinforcement of sustainability values and the role of forests in climate change mitigation. This activity represents a form of community service intervention as it is oriented toward knowledge transfer, strengthening participants’ initial capacity, and fostering environmentally responsible attitudes. Post-activity evaluation was conducted using a descriptive quantitative approach through questionnaires. The evaluation results indicate that the public lecture, as an educational intervention in community service activities, had a positive initial impact on the target participants, with approximately 90% improvement in the knowledge dimension and 91% in the behavioral dimension. These findings suggest that public lectures contribute to strengthening climate literacy and fostering sustainable behavior within the university environment. This model can be replicated as an initial development approach for new students toward achieving a sustainable campus.
