Abstract

Pencemaran logam berat dapat menimbulkan pengaruh negatif terhadap lingkungan perairan terutama organisme yang hidup di dalamnya dan manusia yang mengonsumsi organisme tercemar. Logam Cu (Tembaga) merupakan logam esensial yang keberadaanya dalam jumlah tertentu sangat dibutuhkan oleh organisme hidup, namun dalam jumlah yang berlebihan akan menimbulkan efek racun. Dalam penelitian ini dilakukan pengolahan dan analisis data secara kuantitatif deskriptif. Metode ini digunakan untuk menguraikan konsentrasi Cu (Tembaga) dan memproyeksikan sebaran Cu (Tembaga) pada Sungai Jeneberang. Hasil pengukuran yang memiliki konsentrasi tinggi terjadi pada titik yang letaknya paling dekat dengan muara karena merupakan daerah pertemuan antara sungai dan laut yang dimana hampir semua zat pencemar mengalir pada muara. Sedangkan dari hasil analisis dengan aplikasi MIKE 21 ECOLab memproyeksikan penyebaran Cu (Tembaga) berdasarkan angin, kecepatan arus, debit, kondisi fisik-kimia dan lain-lain.

Abstract

This research aims to find out an overview of the prototype solar power-based Waste Water Treatment Plant (WWTP), the component requirements of the PLTS system as an energy source for the WWTP, and level of efficiency in using solar power plants in IPAL operations. The type of research used is experimental research. Based on the research results a prototype solar power-based IPAL system has been produced with a capacity of 800 liters per hour or 11,200 liters per day (14 operational hours) with a Biotech/biofilter type modified by adding a water filter after the chloronization process. Besides of that, a source of electrical energy for all electrical components of the WWTP with a solar panel and battery capacity of 200 wattpeak and 100 Ah respectively. The efficiency level of the solar panels used reached 88.36% at 12.00 (very sunny weather conditions) with input power above output power in the range 09.00-16.00. With this efficiency, electrical energy can be stored to operate the WWTP at night.

Abstract

Background: The increase in urban population and the growing number of motor vehicles contribute significantly to air pollution. High emissions of nitrogen dioxide (NO₂) from motor vehicles pose significant risks to health. Objective: This study explored the NO₂ dispersion profile from vehicle activity and its impact on the community in Simpang Lima Mandai, a heavy-traffic area and the location of the highest ambient NO₂ concentration in Makassar. Methods: A field survey and AERMOD Gaussian dispersion modeling were used in this quantitative study. Traffic volume, vehicle type, speed, and segment length were classified as primary data, while emission factors (EMEP/EEA 2019; MOVES) BMKG Makassar's meteorological data were classified as secondary data. A bottom-up emissions inventory was used to calculate NO₂ emission loads, and WHO (2021) and PP No. 22/2021 air quality standards were used to compare model results. Results: The model indicated that the average NO₂ concentrations over 1 h (348.8 µg/m³) and over 24 h (82.49 µg/m³) represented high exposure risk in the Simpang Lima Mandai area. The residents from the nearby settlements were found to be more vulnerable because of their long-term residence in the polluted area, with a weekly exposure of 4,452 µg/m³. Motor vehicles are a significant contributor to NO₂ pollution, according to the study. Conclusion:Motor vehicle NO₂ emissions at Simpang Lima Mandai are higher than WHO standards, and the highest exposure was recorded for neighboring residents at 4,452 µg/m³/week. We recommend evidence-based interventions such as enhanced traffic management, additional green buffers, and periodic NO₂ monitoring to protect these high-exposure communities.
