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

Domestic waste comes from households that must be treated. Based on the Minister of Environment and Forestry Regulation Number P.68/Minister Environment and Forestry-Secretary General/2016 concerning Domestic Wastewater Quality Standards, the government has set a maximum limit for waste water that can be disposed of to the environment or receiving water bodies. includes pH, TSS and COD parameters. This is useful for overcoming the problem of environmental pollution caused by wastewater. Waste water that is not managed properly will have an impact on human health. environmental pollution is harmful to humans. Domestic sewage treatment using a titanium dioxide photocatalyst shows the results of testing the pH value on domestic waste as shown below, showing that overall the concentration of parameters has increased the pH value decrease 90% from acidic to normal with the best pH value with a value of 6.57 at a contact time of 210 minutes of mass catalyst 2.5 grams. Parameter concentration decreased TSS value from initial value of 157 mg/L to normal with the best TSS value of 94 mg/L at contact time of 210 minutes with catalyst mass of 2.5 grams. COD value at contact time of 210 minutes with a mass of 2.5 grams of catalyst with a value of 2861 mg/L. COD value affects the time and mass of the catalyst (1). a decrease of 40.1% where the TSS value meets the quality standard, and the COD value has decreased by 31%. Addition of further processing to get a better COD.

Abstract

Indonesia has various types of vegetation which are used as natural coagulants or biocoagulants. Coagulants can be divided into chemical coagulants and natural coagulants (biocoagulants). Biocoagulants are more environmentally friendly and can be obtained from natural ingredients, both animals and plants, one of which is Moringa seeds. Moringa seeds or with the Latin name Moringa oleifera are a type of plant from the Moringaceae family. From several previous studies, Moringa seeds were used as a more economical and environmentally friendly wastewater treatment method. Moringa seed biocoagulant in powder form is made from ripe and old moringa seeds and contains less than 10% water. Moringa seed biocoagulant contains 4αL-rhamnosyloxy-benzylisothiocyanate and is a determinant of coagulation effectiveness. This active substance is able to absorb pollutants in waste water. This research aims to treat tofu waste with moringa seed biocoagulant in reducing pollutant parameters, namely TSS (Total Suspended Solid) and COD (Chemical Oxygen Demand). Results of the removal of pollutants from moringa seed powder biocoagulant in tofu waste water the efficiency value obtained for each TSS parameter, and the COD for the TSS parameter is 54.4%. and for the COD parameter of 14.6%, it can be concluded that the efficiency value for each parameter still does not meet the effectiveness value.

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

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.

Abstract

Batik production process generates liquid waste primarily from dyeing and de-waxing processes. This waste, if not managed properly, can pose environmental challenges. This study explores the potential of Eco-photocatalysis using TiO2 (Titanium Dioxide) for treating wastewater from the batik industry. The process involves utilizing ultraviolet (UV) light and a catalyst to enhance the degradation of parameters such as pH, TSS (Total Suspended Solids), and color. Using a reactor containing four 8-watt UV lamps and maintained agitation at 1100 rpm. The catalyst used is Titanium Dioxide (TiO2) (3 grams). The procedure encompassed varying contact times (60, 120, and 180 minutes) and lamp quantities. The results demonstrate that TiO2-assisted Eco-photocatalysis effectively reduces organic and inorganic pollutants in treated water till pH, 6,73, TSS 70 mg/L and color 0,99 Pt-Co.
