Abstract

The air existence on the surface of the earth is one of the important factors for the survival of living things on it. Indonesia’s quality of ambient air has decreased and it is categorized as not good for sensitive groups. The biggest cause of air pollution comes from motor vehicles, of which 85% is from combustion in motorized vehicle engines. Trembesi is the most effective plant in adsorbing pollutant carbon in the air. Activated charcoal is the carbon that has better absorption of cations, anions and the molecules of organic and inorganic compounds. This study aims to create a pollutant filter equipment for CO and CO2 made from Trembesi leaves activated charcoal. This research was conducted by creating an air pollutant filter with 3 different types of adsorbent, namely adsorbent made from paper pulp, trembesi leaves extract adsorbent, and trembesi leaves activated charcoal adsorbent. The data collection used 2 types of vehicles with different year of release and engines. The measurement of pollutant concentration using a Gas Analyzer instrument tester with Korean Iyasaka AET-4000Q type. The result of this study showed that the best adsorbent is activated charcoal from trembesi leaves with 100% adsorption of CO and 36,29% adsorption of CO2 using 2018 Toyota Agya car Dual VVT-I engines with eco indicator technology, and for 1988 SE 1,3 Starlet car with a carburetor type engine successfully adsorb CO by 9,65% and 7,2% for CO2.

Abstract

Water is a basic human need. The use of water is very complex, among others, for drinking, cooking, bathing, washing, agriculture, fisheries, and so on. Coastal areas are often faced with the problem of limited water resources. In terms of quantity, coastal areas generally have abundant water, but it is often difficult to obtain water for various uses, due to inadequate quality. Limited water resources in coastal areas are related to the scarcity of fresh water that can be used as clean water. This study aims to desalinate brackish water into fresh water that can be used as clean water for sanitation hygiene needs. The process of desalinating brackish water into clean water uses the multimedia filtration method. Filtration is a process of separating solids from fluids (liquids or gases) that carry them using a porous medium or other porous material to remove as much of the suspended and colloidal fine solids as possible. The filtration media used in this study were activated carbon, silica sand, zeolite and gravel. These media are effective in reducing salinity and turbidity in brackish water.

Abstract

Tofu liquid waste comes from the washing process, boiling, and printing on tofu production. Tofu liquid waste is usually directly discharged into rivers or sewers which can have a negative impact on the environment. Tofu wastewater treatment with activated charcoal adsorption methods can reduce the concentration of pollutants contained in the waste. This research was conducted to determine the effect of variations in stirring speed in the removal of COD and TSS levels in tofu liquid waste. The adsorbent used in this study was activated charcoal from the skin of jengkol (Pithecellobium lobatum) carbonized at 350ºC which was then activated using 1M HCL. The adsorption process in this study used a mass of 2 g of activated charcoal; 4 g, 6 g and 8 g and stirring speed 60 rpm and 120 rpm. The initial concentrations of COD and TSS were 5140 mg/L and 605 mg/L. The results of the research that have been carried out show that the stirring speed and mass of the adsorbent affect the levels of COD and TSS as well as the effectiveness and adsorption capacity. A significant decrease in COD and TSS levels occurred in the treatment using 8 g of activated charcoal and a stirring speed of 120 rpm. The COD value obtained was 1137 mg/L, TSS was 103 mg/L and the efficiency value obtained was COD of 77.88% and TSS of 82.98%.

Abstract

One solution for domestic waste treatment is the operation of a communal IPAL (WWTP, Wastewater Treatment Plant). This is in accordance with SDG's (Sustainable Development Goals), national and regional policies related to sustainable sanitation management. In Banda Aceh, the Sanimas (Community sanitation) program has been and is being implemented in 40 gampongs (villages) which are classified as slum areas. This study aims to determine the results of the effluent processing of the IPAL system (pH, BOD, COD, TSS, ammonia, Total Coliform, Oil/Fat parameters) to see whether the IPAL system that has been built is operating properly. There were five IPALs studied, namely in Gampong Peunayong (Dusun Cendrawasih), Gampong Tibang (Dusun Tgk. Meurah, Dusun Tgk Meulinje, Dusun Tengku Meulagu), and Gampong Panteriek (Dusun Jeumpa). The results of the effluent wastewater test showed that in all WWTPs, the BOD and COD parameters still exceeded the wastewater quality standards, and in one WWTP, the total Coliform parameter was >1,000/100 ml (quality standard >3,000/100 ml).

Abstract

Indonesia saat ini memiliki kapasitas produksi tahu 2,56 ton/tahun. Limbah cair tahu yang dialirkan langsung ke saluran pembuangan tanpa di olah terlebih dahulu akan menjadi masalah bagi lingkungan. Salah satu teknik pengolahan air limbah adalah dengan menggunakan trickling filter dengan media bioball. Penelitian ini bertujuan untuk mengolah limbah cair tahu dengan trickling filter menggunakan media bioball. Sampel limbah cair tahu sebanyak 40 Liter, di peroleh dari Desa Sukaramai, Kecamatan Baiturrahman, Kota Banda Aceh. Penurunan konsentrasi limbah cair diamati melalui parameter nilai COD, pH dan TSS dan pengukuran total koloni pada biofilm. Eksperimen dilakukan dengan variasi jumlah media bioball sebanyak 50, 100 dan 150 bioball dan variasi waktu 8, 24, 72 dan 168 jam. Pada pengukuran COD dengan variasi 150 bioball menggunakan waktu 168 jam didapatkan penurunan yang signifikan yaitu sebesar 78,79%. Sementara, pada pengukuran TSS dengan variasi 150 bioball menggunakan waktu 168 jam didapatkan hasil penurunan sebesar 75,93%. Sedangkan untuk eksperimen peningkatan pH didapatkan hasil yaitu sebesar 8,3. Hasil penelitian menunjukan bahwa variasi jumlah media bioball dan variasi waktu mempengaruhi proses degradasi dalam reaktor trickling filter dan telah memenuhi standar baku mutu sesuai dengan peraturan Menteri Lingkungan Hidup Republik Indonesia Nomor 5 Tahun 2014. Serta, hasil total koloni bakteri yang didapatkan pada variasi 150 bioball selama 28 hari yaitu 6,2×105 Cfu/ml menunjukkan bahwa semakin lama masa inkubasi biofilm dapat mempercepat laju degradasi terhadap parameter COD, TSS, dan pH pada limbah cair tahu.

Abstract

Domestic liquid waste contains high organic matter when it enters the body of water causing environmental pollution. Utilization of natural coagulants such as bittern can be used in the process of processing domestic liquid waste. This study was conducted to be able to know the effectiveness and optimum dose of bittern biocoagulants in lowering the levels of turbidity, TSS, COD and BOD in domestic wastewater. Based on the initial test results of domestic wastewater pH values of 7.2 turbidity, TSS, and COD of 70 NTU, 326 mg/L, and 716 mg/L and 19.02 mg/L. The results showed that there was an influence on the dose of bittern coagulants 0, 8, 16 and 24 ml/L with stirring times of 30 minutes and 60 minutes. The optimum dose of bittern coagulants in lowering pH, turbidity, TSS, COD and BOD at doses of 24 ml/L amounting to 8.0, 18 NTU, 94 mg/L, 121 mg/L and 9.39 mg/L. Effectiveness of bittern coagulants in domestic liquid waste treatment for pH and BOD levels is as expected because it meets established quality standards, while the parameters of turbidity, COD and BOD results are still passed the quality standards.

Abstract

The increase in vehicle washing services has a major impact on the environment, human health and ecosystems in water bodies. One method of treating vehicle washing liquid waste using a filtration system has been proven to be effective and capable of breaking down pollutants contained in wastewater. However, filtration using activated carbon, silica sand, zeolite and gravel media with different variations and doses of media thickness to reduce levels in the parameters pH, TSS, COD and Phosphate has not been studied. This study was conducted to determine the effect of variations and doses of filter media and their effectiveness in reducing the levels of TSS, COD, pH and Phosphate in vehicle washing waste, with variations in the thickness of activated carbon media 10, 20, 25 cm and silica sand, zeolite, gravel 15 , 20 cm. The results showed that activated carbon, silica sand, zeolite and gravel media were able to reduce TSS, COD, pH and phosphate levels. The decrease in levels is highest in the 6th variation. The percentage of TSS is 97.13%, COD is 93.93%, Phosphate is 74% and a decrease in pH 7. From the data presented, it can be seen that all variations are able to reduce levels of pollutant parameters. in vehicle washing waste.

Abstract

In Islam, the most frequent need for water is when performing ablution activities. Prophet Muhammad SAW used only 1 mudd of water (about two-thirds of a liter) or about 0.67 liters for ablution. This study aims to determine the efficiency of using a Swing Check type of flow limiter on a water faucet related to ablution activities. The results showed that the flow limiter (valve) of the Swing Check type was able to efficiently use water in an average of 43%. With the Swing Check valve wudu volume per individual is 17.68 l/person before the flow limiter is used this valve and 10.09 liters/person. With this research, it is hoped that in the future we can update technology that can save water, not only in saving water but also in maintaining the existence of water, especially the involvement of water conservation also plays an important role in water conservation.
