Abstract

The pulp industry is one of the sectors contributing to climate change, especially through greenhouse gas (GHG) emissions from wastewater treatment. This study aims to estimate the GHG emissions from the aerobic wastewater treatment applied by PT X using the IPCC method and to calculate the potential emission reduction by implementing anaerobic treatment. The results show that the COD concentration of the pulp industry effluent ranges from 500 to 600 mg/L. GHG emissions in the form of CH₄ are considered to be zero since the aerobic process does not produce CH₄, while CO₂ emissions from electricity consumption for the activated sludge aerator are 9.48 tons of CO₂/day. The implementation of anaerobic treatment is proposed as a solution to reduce GHG emissions by reducing electricity consumption and sludge production. Anaerobic treatment also has the potential to produce biogas, which can be used as an energy source for pulp production activities. The potential electrical energy from biogas utilization is estimated to be between 14.88 and 24.34 MWh, which is significant in reducing dependence on non-renewable energy sources while also reducing GHG and air pollutant emissions.

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

Sekolah Dasar Negeri 02 Way Huwi di Kabupaten Lampung Selatan menghadapi berbagai tantangan dalam penerapan Perilaku Hidup Bersih dan Sehat (PHBS), mulai dari keterbatasan sarana cuci tangan, rendahnya kebiasaan mencuci tangan pakai sabun, konsumsi jajanan yang tidak memenuhi standar higienitas, hingga rendahnya kesadaran pemilahan sampah. Kondisi ini menimbulkan risiko kesehatan yang serius, khususnya meningkatnya potensi penyakit berbasis lingkungan dan makanan pada siswa. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman sekaligus membentuk kebiasaan hidup sehat pada siswa melalui pendekatan edukasi yang interaktif, praktis, dan menyenangkan. Metode pelaksanaan meliputi persiapan, penyuluhan dalam bentuk ceramah interaktif, pemutaran video edukasi, demonstrasi enam langkah cuci tangan menurut standar WHO, simulasi pemilahan sampah organik dan anorganik, kuis berhadiah, serta penyediaan media visual berupa poster edukatif. Evaluasi dilakukan melalui pre-test dan post-test dengan instrumen bergambar untuk menyesuaikan dengan tingkat pemahaman siswa sekolah dasar. Sebanyak 26 siswa dari kelas IV dan V berpartisipasi aktif dalam kegiatan ini. Hasil evaluasi menunjukkan adanya peningkatan signifikan pengetahuan siswa dengan rata-rata kenaikan sebesar 70%, di mana siswa kelas V mencatat capaian lebih tinggi dibandingkan kelas IV. Dampak positif lain yang terlihat adalah keterampilan siswa dalam mencuci tangan dengan benar, meningkatnya kesadaran dalam memilih jajanan sehat, serta kemampuan memilah sampah sesuai jenisnya. Keberhasilan kegiatan ini menunjukkan bahwa pendekatan edukatif berbasis praktik langsung efektif untuk meningkatkan kesadaran dan membentuk perilaku sehat berkelanjutan pada siswa sekolah dasar.
