Abstract

This study aims to examine the effect of the ratio of plastic waste and sawdust on the mechanical characteristics of alternative lightweight building materials. Plastic waste is used as a thermoplastic binder, while sawdust acts as a lightweight aggregate with insulating properties. The composition of the mixture is varied in several ratios (90:10, 80:20 and 70:30) to determine its effect on the mechanical properties of compressive strength test specimens according to SNI 03-3958:1995 from the resulting mortar product. The manufacturing process involves mixing melted plastic waste with sawdust, then molding and releasing. The test results show that increasing the proportion of sawdust can significantly reduce the compressive strength. Conversely, a higher plastic ratio increases the compressive strength but produces a heavier material. The optimum composition was found at a ratio of 90:10 (plastic: sawdust), which provides a balance between strength, lightness, and insulating properties. This study shows the potential for utilizing plastic waste and sawdust as environmentally friendly building materials with feasible functional performance and in accordance with compressive strength standards.

Abstract

Proper environmental sanitation is an essential component in ensuring a healthy and safe quality of life for communities. Taipa Subdistrict in Palu City has experienced significant growth in infrastructure and population; however, challenges remain in the areas of sanitation and household waste management. This study aims to evaluate the environmental sanitation conditions in Taipa and their impact on public health. The research employed a descriptive quantitative method using a survey approach conducted on 512 households through field observations, interviews, and questionnaires. The results revealed that most residents rely on bore wells as their main sources of clean water and drinking water, while the use of piped water (PDAM) remains limited. Nearly all households have access to healthy latrines and use septic tanks for fecal waste disposal. However, the management of used cooking oil and the practice of open burning of waste remain environmental concerns that require attention. The majority of houses have floors and walls that meet environmental health standards. These findings indicate that although basic sanitation has been categorized as fairly adequate, efforts in public education and improvement of waste management systems are still needed to ensure sustainable environmental health in the community.

Abstract

Environmental pollution issue from solid waste, especially plastic, is a global concern because it harms ecosystems and human health. A major cause is the use of single-use plastics and styrofoam, which do not break down easily. In Palu City, this problem led to the issuance of Palu Mayor Regulation Number 40 of 2021 concerning the Restriction on the Use of Single-Use Plastic Packaging and Styrofoam. This study evaluates how well this policy has been implemented and its effect on reducing plastic waste. Using descriptive quantitative methods to analyze secondary data of waste generation and achievements in waste handling from the National Waste Management Information System (SIPSN) for the years preceding (2020) and following (2024) the regulation’s implementation. The results show a significant drop in plastic waste from 30.00% to 10.43%, along with decreases in daily and yearly waste amounts. The recycling rate also improved from 0.51 to 0.58, indicating an improvement in waste management, especially through the use of TPS3R. The study recommends stronger public education, better monitoring, and improved facilities to ensure the policy’s success and sustainability in Palu City.

Abstract

Aktivitas transportasi yang menggunakan kendaraan berbahan bakar fosil menyumbang pencemaran udara dalam bentuk gas dan partikel. Kualitas udara yang buruk di wilayah perkotaan umumnya disebabkan oleh tingginya kadar polutan dari emisi gas buang kendaraan, baik milik pribadi maupun umum. Salah satu kota yang mengalami peningkatan signifikan dalam jumlah kendaraan adalah Kota Makassar. Bertambahnya jumlah kendaraan bermotor berdampak pada meningkatnya emisi yang mencemari lingkungan dan membahayakan kesehatan masyarakat. Salah satu jenis polutan yang dihasilkan kendaraan bermotor adalah Total Suspended Particulate (TSP). Penelitian ini bertujuan untuk mengevaluasi tingkat konsentrasi TSP dalam udara ambien serta hubungannya dengan kecepatan angin. Data diperoleh melalui pengukuran langsung menggunakan alat High Volume Air Sampler (HVAS). Penelitian dilakukan pada enam ruas jalan di Kota Makassar selama tiga waktu sibuk (peak hour) setiap harinya di masing-masing lokasi. Hasil pengukuran menunjukkan bahwa konsentrasi TSP tertinggi mencapai 398,67 ?g/Nm³, yang tercatat di Jalan Perintis Kemerdekaan. Angka ini melebihi ambang batas kualitas udara ambien berdasarkan Peraturan Pemerintah Republik Indonesia No. 41 Tahun 1999. Analisis korelasi antara kecepatan angin dan konsentrasi TSP menunjukkan adanya hubungan yang cukup kuat, dengan nilai korelasi sebesar 0,709.
