Abstract

Two-wheeled motor vehicles are a major source of urban air pollution. This study investigates the emissions of carbon monoxide (CO) and hydrocarbons (HC) from motorcycles operating within the Environmental Engineering Department of Universitas Tadulako. Emission data were collected using direct measurements with an automotive emission analyzer across various motorcycles differing in age, fuel type, and engine condition. The findings reveal that, although the average emission levels generally meet the national standards (Ministerial Regulation No. 8/2023), motorcycles using lower-grade fuel (Pertalite) emit higher concentrations of CO and HC compared to those using higher-grade fuel (Pertamax). Furthermore, both CO and HC emissions increase with the age and mileage of the vehicle. The correlation analysis indicates that older vehicles and those with higher mileage tend to release more pollutants due to reduced engine efficiency. These results underscore the importance of regular vehicle maintenance, the use of higher-quality fuels, and awareness campaigns to reduce air pollution on campus. The study supports the development of environmentally friendly transportation policies within educational institutions. ASSESSMENT OF TWO-WHEELED VEHICLE EMISSIONS IN THE VICINITY OF THE ENVIRONMENTAL ENGINEERING DEPARTMENT, UNIVERSITAS TADULAKO, INDONESIA

Abstract

Penelitian ini bertujuan untuk mengkaji perkembangan penelitian PLH di kawasan Asia Tenggara selama periode 1991 hingga 2025. Kajian dilakukan melalui telaah literatur sistematis terhadap artikel-artikel yang diterbitkan di jurnal bereputasi nasional dan internasional. Analisis difokuskan pada tren publikasi, topik dominan, pendekatan metodologis, serta kontribusi praktis terhadap kebijakan dan praktik pendidikan. Hasil menunjukkan adanya peningkatan signifikan dalam jumlah publikasi sejak tahun 2000, dengan puncak pada dekade 2010-an. Topik yang paling sering dibahas meliputi pendidikan berbasis konservasi, partisipasi komunitas, dan integrasi isu lingkungan ke dalam kurikulum formal. Indonesia dan Malaysia menjadi negara dengan kontribusi publikasi tertinggi. Meskipun demikian, masih ditemukan tantangan seperti keterbatasan data longitudinal, rendahnya kolaborasi antar-negara, serta minimnya pendekatan transdisipliner. Penelitian ini merekomendasikan perlunya penguatan kurikulum PLH, pengembangan platform kolaboratif antar lembaga pendidikan di kawasan, serta integrasi teknologi digital dalam penyampaian materi PLH. Temuan ini diharapkan dapat menjadi dasar perumusan strategi regional yang lebih inklusif dan adaptif dalam menghadapi tantangan lingkungan di masa depan. Dengan memperkuat riset dan praktik PLH, kawasan Asia Tenggara memiliki potensi besar untuk menjadi pelopor dalam pembangunan berkelanjutan yang berbasis pada literasi ekologi masyarakat.

Abstract

Tourism-driven activities have increasingly contributed to marine microplastic (MPs) pollution, particularly in island ecosystems. This study assesses the abundance, characteristics, and spatial distribution of MPs in Gili Trawangan, Indonesia, by analyzing samples from coastal water, sediments, and fish across three zones: a seaport, recreational beach, and mangrove area. Standardized filtration, density separation, and FTIR spectroscopy were used to identify MPs types and polymers. Results show the highest MPs concentrations in coastal water at recreational beaches (19.25 particles/L), sediment at seaports (23.15 particles/kg), and fish near seaports (17.5 particles/individual), indicating elevated risks of bioaccumulation. Fragments and fibers were the dominant forms, with prevalent polymers including PS, PE, and LDPE, mostly in black, blue, and red colors. The mangrove area exhibited lower MPs levels due to its natural filtration capacity but still showed MPs presence in biota. This multi-compartment approach highlights a clear link between tourism intensity and MPs contamination. The findings provide new insights for designing localized interventions, including waste reduction strategies and regulatory measures. By integrating ecological and anthropogenic factors, this study supports the development of sustainable tourism policies to mitigate MPs pollution and protect coastal biodiversity.

Abstract

The incorporation of wood dust and crumb rubber waste as filler in polymer matrix composite still requires in-depth evaluation of mechanical properties because they have different characteristics. This study evaluates the tensile, flexural, and hardness properties of epoxy composites reinforced with various fractions of wood dust and crumb rubber (5, 10, and 15%). The results showed that the composite with 5% crumb rubber produced the highest tensile strength of 15.52 MPa (CR5), while the highest flexural strength was 30.46 MPa (CR10), and the highest hardness was 75.9 HRC (CR15), indicating superior performance for CR fillers. The observations of the fracture surface showed that increasing the fraction of wood dust contributed to lowering the mechanical performance due to the relatively large distribution of voids and agglomeration. This finding confirms the importance of filler type and fraction selection on composite performance. Future research is recommended to explore filler surface modification and hybrid combinations to improve dispersion and bonding between phases in composites.

Abstract

When exposed to ultraviolet (UV) light, paper trash could release dissolved organic matter (DOM) as a disinfection byproduct (DBP) precursor in water. This study was undertaken to assess the regulated DBPs, trihalomethanes-4 (THM4) generation potential, and estimated cytotoxicity of paper trash soaked in water during UV radiation. The UV irradiation was carried out at 1, 6, 12, 24, and 48 hours. The released organic material was determined using ultraviolet-visible (UV-Vis) adsorption at wavelengths ranging from 200 to 700 nm. Chlorination was carried out for 24 hours to determine THM4 formation potentials. According to the research findings, the longer the radiation period, the more THM4 species are formed in plain paper samples. On the other hand, the production of trichloromethane (TCM) on paper samples containing writing decreased as the UV radiation period increased. THM4 levels reached 103.12 and 150.57 µg/L for plain and writing paper samples, respectively. UV absorbance at 272 nm (A272) shows a 92% association with THM4 production, making it suitable as an initial characterization approach. Paper trash pollution in water could form carcinogenic DBPs, THM4, if used as a water source in a water treatment plant using chlorine disinfection.

Abstract

Urban sanitation remains a critical public health issue, with community participation recognized as a key factor in the success of sanitation programs. This study aims to explore the multi-dimensional factors influencing community participation in the urban setting of Koja. Through a mixed-methods approach, including surveys, interviews, and observational studies, we investigated how socio-demographic factors such as age, gender, income, and occupation, as well as aspects of sanitation governance, infrastructure, and educational interventions, interplay to affect community engagement. The study revealed that while infrastructure and access are crucial, socio-economic and gender-related barriers significantly impact participation levels. Educational level emerged as a strong predictor of engagement, indicating that awareness and knowledge play a critical role in motivating community involvement. Furthermore, sanitation governance and the quality of policies and monitoring were found to be instrumental in shaping public attitudes towards participation. The research highlights the necessity for integrated and inclusive sanitation policies that address the local context and socio-economic diversity of urban populations. The findings underscore the importance of targeted educational campaigns and the fostering of collaborative community relationships to enhance participation in sanitation programs. This study contributes to the discourse on urban sanitation by providing a nuanced understanding of the complex factors at play in community-based sanitation efforts, offering insights for policymakers to improve public health outcomes.

Abstract

Pertumbuhan penduduk telah menyebabkan peningkatan debit limpasan hujan dan air limbah yang dialirkan ke saluran drainase. Penelitian ini maka bertujuan mengevaluasi volume drainase di Jalan Taud, Kota Medan, apakah tetap dapat menampung air buangan hingga perkiraan 50 tahun mendatang. Saluran yang diamati mulai dari Rumah Kosan (Jalan Taud No. 112) hingga unit usaha Gulo Pangkas (Jalan Taud No. 16) dengan panjang 1.000 m. Evaluasi ini mempertimbangkan pertambahan jumlah penduduk, debit air limbah domestik, debit limpasan hujan, timbulan sedimen, serta proses evapotranspirasi sebagai bagian dari siklus air. Berdasarkan investigasi, diketahui volume drainase di Jalan Taud saat ini masih dapat melayani masyarakat hingga tahun 2047. Hasil evaluasi yang dilakukan pada saluran drainase terpilih di Jalan Taud, Kota Medan, diperoleh kesimpulan bahwa drainase tetap dapat menampung air buangan dari campuran limpasan hujan dan air limbah domestik hingga 25 tahun mendatang. Intensitas curah hujan pada 10 tahun mendatang di tahun 2032 berkisar 5,87 mm/jam, 6,04 mm/jam di tahun 2047, dan 6,56 mm/jam di tahun 2072; sedangkan debit air limbah total yang dihasilkan dari aktivitas domestik adalah 10.71 x 10-2 L/orang/hari (2032), 12.24 x 10-2 L/orang/hari (2047), dan 17.24 x 10-2 L/orang/hari (2072). Dengan panjang saluran yang diamati 1.000 m, lebar saluran rata-rata adalah 0,82 m, dan kedalaman 0,90 m, didapatkan volume drainase eksisting adalah 590,4 m³. Perlu upaya pengelolaan rutin seperti pembersihan saluran dari sampah dan sedimen secara berkala, serta sosialisasi kepada masyarakat untuk menjadikan drainase tetap berfungsi sebagaimana mestinya.
