Abstract

Tofu production is known to generate large amounts of wastewater containing a variety of organic compounds, chemicals, and potentially hazardous substances. It is very important to apply proper treatment of harmful substances that impact this wastewater. The aim of this study is to explore advanced techniques for treating tofu wastewater by combining multilevel filtration and TiO2 photocatalysis methods. To evaluate the efficiency of the treatment process, influent and effluent parameters, including pH, total suspended solids (TSS), and chemical oxygen demand (COD), are carefully monitored and measured. The results clearly demonstrate the impressive removal efficiency achieved through the combined use of multilevel filtration and TiO2 photocatalysis in treating tofu wastewater. The treated wastewater showed a promising efficiency in pH (100%), a significant decrease in TSS (40%), and COD (72%). the final measurements of pH met the standards set by government regulations, indicating successful remediation of these specific parameters. Even though TSS and COD haven't met the standard limits, each of them shows a very promising efficiency improvement. Towards the end of this study, it is suggested that the combination of these methods holds promise for effectively remediating tofu wastewater.

Abstract

Tree planting has the aim of reforestation and greening for conservation, greening is an effort to create a beautiful and useful area and greening is increasing the area of ​​RTH (Green Open Space). This community service is at SD N 2 Senawar. Community service aims to increase tree planting in schools and foster students' character to love the environment. Community service methods are presentation, discussion and practice methods. Transfer of knowledge and technology given to residents of SD N 2 Senawar school. community service activities participants can find out about tree planting and reforestation activities properly and can reduce the impact of environmental pollution.

Abstract

This research aims to determine the magnitude of the CO concentration in the ambient air at the Y T-junction Simpang Rimbo, Jambi City using a CO meter. Observations were carried out for 3 days (Sunday, Monday and Tuesday). Sundays and Mondays are held at 2 different times, namely the afternoon and evening. 1 day observation on Tuesday with 4 different times, namely Morning, Afternoon, Afternoon and Night. Each observation time at 1 point is carried out for 60 minutes. The results of the 3 day study showed that the highest CO concentration occurred on Tuesday during the day, namely 279,424.4 ??/??3, the lowest CO concentration occurred on Sunday at night, amounting to 63,426.27 ??/??3. Meanwhile, observations for 1 day on Tuesday showed that the highest CO concentration occurred in the afternoon at 9.0056 ??/??3. The CO concentration was higher when measuring for 3 days, this was due to the influence of time and the reduction in vehicles passing the observation point on Tuesday 6 February 2024.

Abstract

The aim of this research was to determine the removal of Total Suspended Solids and fatty oils using the grease trap and filtration methods. Based on the results of experiments that have been carried out, the removal efficiency of Total Suspended Solid at various residence times reached 99.09% (12 hours), 97.89% (24 hours), 98.65% (36 hours), 98.89% (48 hours), 99.18% (60 hours), and 99.3% (72 hours). Fatty oil removal over a period of 12 to 72 hours reached 99.99%. The use of grease traps and filters with biochar rubber and sand media shows that this treatment has proven effective in reducing levels of Total Suspended Solids and fatty oils to meet domestic wastewater quality standards.

Abstract

Rainfall simulator is a useful tool for controlled infiltration and runoff from open space application conditions in capturing rainwater during the rainy season. Rainfall simulators provide several benefits urban in area which can improve a quality the urban of environment, can reduce heat energy in the room, cooling process through roof closure, evapotranspiration and the heat insulator. The first factors that influence runoff consist of rain intensity and watershed characteristic factors. This research aims to determine the effect of variations in rain intensity on the resulting runoff discharge, rain erosivity index, and erosion rate using experimental methods in making a rain simulator. This study was carried out with varying slopes of 0o, 10 o, 15 o, 25 o, and 35 o with different runoff time and volume at each slope of the roof garden. Roofs that use plants on average only produce 1147.2 ml of runoff, while roofs without plants produce an average of 1492 ml of runoff with a difference of 345 ml and a percentage of 26%.

Abstract

Limbah rumah potong hewan (LRPH) mengandung senyawa organic dan anorganik yang berpotensi mencemari lingkungan, seperti COD, ammonia, minyak lemak dan pH yang tidak stabil. Satu diantara metode yang diterapkan dalam pengolahan limbah cair RPH yaitu elektrokoagulasi alumunium. Penelitian ini bertujuan untuk mengetahui pengaruh kuat arus dab waktu kontak pada proses elektorkoagulasi terhadap penurunan kadar COD, ammonia dan minyak lemak. Proses elektrokoagulasi dilakukan menggunakan elektroda aluminium dengan variasi kuat arus 10 A/m2, 20 A/m2, 30 A/m2 dengan durasi kontak yaitu 60 menit, 120 menit, dan 180 menit. Hasil penelitian membuktikan bahwa peningkatan kuat arus dan durasi kontak berpengaruh signifikan terhadap penurunan kadar COD, ammonia, dan minyak lemak serta perbaikan nilai pH. Efisiensi tertinggi dicapai pada  kuat arus 30 A/m2 dengan durasi kontak 180 menit untuk parameter COD sebesar 76,26%, ammonia sebesar 59,82%, minyak lemak sebesar 66,93%, dan nilai pH mengalami peningkatan dari 6,93 sampai 8,63. Hasil ini menujukkan bahwa elektrokoagulasi cukup efektif dalam menurunkan parameter pencemar dalam limbah cair RPH.
