Abstract

The Asam River is one of the tributaries located along the RT 15 area of Paal V Village, the Asam River crossing the residential area of this river has the potential to be polluted by domestic waste. Based on data on the water quality of the Asam River according to the Jambi City Environmental Service in 2020, the water quality of the Asam River has exceeded the surface water quality standard on the parameters of TSS, turbidity, pH, BOD, COD and ammonia. The purpose of the study was to determine the disposal of domestic wastewater and to determine the quality status of the acid river in terms of the pollution index method and to know the plan for controlling the pollution of the acid river with the influence of domestic waste. Based on the calculation of the status of the Asam River water quality, which was determined using the Pollution Index (IP) method, the points AP-1 (Upstream) and AP-2 (Downstream) were in a “Lightly Polluted” condition. This is because the results of the ammonia and turbidity parameter tests at the AP-1 (Upstream) and AP-2 (Downstream) points that exceed the established quality standards. Efforts to control river pollution can be carried out by making riparian buffer strips or planting vegetation on the banks of the Asam River. , the manufacture of communal WWTPs in every existing sub-district along the Asam River and tightening of wastewater quality standards for industrial and domestic activities which must not exceed the water quality standard according to its class.

Abstract

Wastewater treatment is the main element in the success of a business in environmental management and monitoring, for this reason it is necessary to carry out maintenance and evaluation so that the sustainability of environmental protection continues. The crude rubber industry (crumb rubber) generally processes rubber in several stages, starting from sorting raw materials, cleaning bokars, macro mixing, pre-drying, crushing, drying and pressing, of course, this produces waste. The research method is evaluating the quality of wastewater from each treatment unit at the WWTP production of crumb rubber, as well as evaluating the WWTP units based on design criteria that are planned and described analytic descriptively. upon admission, namely COD of 12.876 mg/L, TSS of 1.112 mg/L, BOD5 of 980 mg/L, Ammonia 2.3 mg/L, Nitrogen 96 mg/L, pH 6.3. The results at the outlet are COD 19.35 mg/L, TSS 58.67 mg/L, BOD5 35.1 mg/L, Ammonia 0.2 mg/L, Nitrogen 10 mg/L, pH 7. While the WWTP unit design inefficient in terms of design criteria, this is because the residence time is calculated too quickly, therefore it is necessary to analyze the suitability of dimensions in order to meet the required design criteria.

Abstract

One of the biggest environmental issues today is plastic waste. This waste cannot be avoided and continues to increase which in its decomposition takes 50-100 years and will be fragmented into smaller forms called microplastics. Microplastic measuring < 5 mm with various shapes. The people of the Nipah Panjang area dispose of plastic waste into the Batanghari River which is likely to cause microplastic content. To determine the number of microplastics, it is necessary to identify the abundance of microplastics found in the Nipah Panjang area on the Batanghari River using quantitative methods. The tool used is Planktonet mesh 150 with a diameter of 20 cm. The sampling process was carried out for one day with two samplings, namely in the morning at low tide at 09.00-11.00 WIB and in the afternoon at high tide at 15.00 WIB. The study's results were sampling in the morning at low tide with 327 microplastic particles and the highest in the afternoon at high tide, namely 443 microplastic particles. The temperature in the morning and evening ranges from 29°C - 32°C. The results showed that four types of microplastics were found, namely the type of fiber, filament, fragment, and granule. From the four locations of Sungai Air samples, the most microplastic fragments were found with a total of 353 particles, the second most were filament types with a capacity of 191 particles, the third type of fiber with a total of 186 particles, and the least types of granules with a total of 40 particles. Microplastic at low tide is lower than at high tide. The abundance of microplastics from the four sampling locations of river water is 25,666.67 particles/m3.

Abstract

This study aims to determine the effectiveness of the hydrolysis method in the manufacture of glycerol from used waste cooking oil. This experiment was carried out by the Hydrolysis method. The hydrolysis process is carried out by varying the ratio of reactants between the amount of used waste cooking oil & water, namely (20:180; 40:160; 100:100; 140:60 ml). In addition, HCl & KOH solutions are used as catalysts in the hydrolysis process.From the results of the study, the maximum glycerol yield value was 0.79% in the ratio of reactants (20ml used waste cooking oil: 180ml water) with a reaction time of 1 hour, 3% HCl catalyst concentration and a temperature of 100°C.

Abstract

Biochar is a solid material formed from the carbonization of biomass. Biochar is the result of the conversion of organic waste by using the incomplete combustion method with a limited oxygen supply (pyrolysis). Meanwhile, the rubber scrap waste from the production of crumb rubber has not been utilized much other than as a mixture of fertilizer in the soil. This study aims to analyze the effectiveness of biochar as a peat water filtration media and the effect of biochar thickness on removal efficiency. Variations used are 100% biochar, 75% biochar – 25% silica sand, 50% biochar – 50% silica sand with three times repetation in each variation. with peat water test parameters are pH, color and organic matter (KMnO4). Parameters tested were pH, color and organic matter (KMnO4). The results showed that biochar was effective in neutralizing pH where the initial pH increased to 7.2, 4.2, color removal up to 75% and organic matter (KMnO4) up to 83%. The best variation is achieved at a ratio of 50% biochar – 50% silica sand. Variations that use 100% biochar actually provide lower removal efficiency. The combination of biochar with silica sand can further improve pollutant removal in filtration system.
