Abstract

The treatment of soy sauce effluent poses a significant environmental challenge due to its high levels of contaminants. Several studies have shown that the use of Chlorella sp. microalgae can contribute to the degradation of BOD, COD and TN using a moving bed biofilm reactor (MBBR). Therefore, this study aims to determine the effectiveness of a consortium of Chlorella sp. microalgae and indigenous microbes in treating soy sauce wastewater using an MBBR with an anoxic-oxic process. This research uses a continuous system with variations in the volume of alkaline media (20%, 40%, 60%) and sampling times (14, 26, 38 hours). The best variation for the reduction of organic content in soy sauce wastewater using the Chlorella sp. microalgae consortium achieved a BOD reduction of 71.54%, COD reduction of 74% and TN reduction of 71.89%, all at a sampling time of 38 hours. Meanwhile, the organic reduction using indigenous microbes showed a BOD reduction of 86.76%, COD reduction of 88.24% and TN reduction of 82.76%, all at a sampling time of 38 hours.

Abstract

Manual sorting of catfish is a labour-intensive process in catfish farming, requiring considerable time and effort. Therefore, an effective and user-friendly automated catfish grading system is required. Currently, several automated sorting systems have been developed using load cells, but these methods are inefficient as they require fish to be sorted one at a time. The method used in this system is similar to the concept of a coin sorter, where catfish flow through holes of different diameters according to their head size. In addition, the system uses a water pump to circulate water from the final storage tank back to the holding tank to help guide the fish to the sorting channel. The water flow rate of the pump can be adjusted using a dimmer, which works by limiting the voltage used by the pump. Testing of the grading system was carried out under two conditions, grading fish of the same size range and grading fish of a significantly different size range. The results showed that sorting fish of the same size range had a higher accuracy (86.1%) compared to sorting fish of a different size range (61.9%). An analysis of the effect of the dimmer on the pump was also carried out, showing that the dimmer can effectively control the water flow rate.

Abstract

StuVent is an application designed to provide information on the health status of infants aged 0-24 months and to detect early stunting. This application displays the classification results of the infant's health status, differentiated by colour, making it easier for users to understand the infant's health status. StuVent is aimed at Posyandu's staff and the general public to help them detect early stunting. The main advantage of this application is its ability to work offline using Bluetooth Low Energy (BLE) connectivity. Users can connect their smartphones to the scales via Bluetooth, allowing the application to be used without an internet connection. This feature is particularly beneficial for users in 3T areas (frontier, outermost and remote regions) where internet access is often limited. StuVent is therefore expected to be an effective tool for monitoring child growth and preventing stunting in various regions.

Abstract

Tofu industry production activities generate wastewater from soy milk coagulation and moulding processes. The high content of organic compounds in tofu industry wastewater, including COD, requires treatment before discharge into water bodies. The high organic content in this wastewater can be used as a substrate in MFC systems. This research aims to analyse the effect of different anode types in the combination of MFCs-ABR reactors on the power density (mW/m²) and COD removal efficiency of tofu industry wastewater. The research method is quantitative, starting with seeding and acclimatization for 21 days, and then analysing the effect of graphite carbon and stainless steel anodes on the performance of MFCs-ABR reactors with different retention times of 24, 48, 72, 96 hours. The results showed that the graphite carbon anode produced the highest power density of 204.13 mW/m² and COD removal efficiency of 60.42% at a retention time of 96 hours.

Abstract

This study aims to evaluate the effectiveness of phytoremediation using plants in reducing chromium (Cr) levels and modifying pH in batik wastewater. The research was conducted using three experimental tanks: Control Tank (without plants), Tank 1 (with 8 plants) and Tank 2 (with 16 plants). The results showed that in the control tank the pH fluctuated and reached 8.1 on the 9th day, while in tank 1 and tank 2 the pH was more controlled with peak values of 7.9 and 8.2 respectively. The most significant reduction in chromium levels occurred in tank 2, with treatment efficacy reaching 70% on day 9, compared to 45% in tank 1 and 10.5% in the control tank. These results indicate that phytoremediation with more plants can significantly improve the treatment efficiency of batik wastewater, making it a potential and environmentally friendly method for industrial wastewater treatment. The phytoremediation method was carried out by observing variations in the number of plants using 3 reactor tanks. The first tank was a control tank, the second tank (BR2) contained 8 plants and the third tank (BR3) contained 16 plants. Samples were taken on days 3, 6 and 9. The results showed that the highest effectiveness in reducing total chromium (Cr) levels occurred in the third tank (BR3) on day 9, with a reduction of 70%.

Abstract

Infusion bottles are one of the largest types of medical waste found in hospitals, reaching 4,732 kg in 2023. Infusion bottle waste is classified as infectious hazardous waste and requires proper handling. One alternative is to use the recycling principle to minimise the generation of infusion bottle waste. This research aims to investigate the potential for reducing infusion bottle waste in hospitals. The research was conducted by determining the generation of infusion bottle waste according to the method in SNI 19-3964-1994. The recycling of infusion bottle waste was carried out through several stages, including emptying, cleaning, disinfecting and drying, and crushing or shredding the infusion bottle waste. The results showed that the amount of IV bottle waste generated in one hospital in Bekasi City was 3.66 kg/day. The potential for disinfection can be achieved by sterilisation using chlorine solution (0.50%) and alcohol (0.70%). With a soaking time of 10 minutes, further utilisation of sterile infusion bottle waste was carried out by shredding the particles into 8.00 - 15.00 mm. The method used in this recycling process can minimise infusion bottle waste by 9.01%.

Abstract

Threats to the environment can come from various sources, including liquid waste from tofu production. This is due to the presence of pollutants in concentrations that exceed quality standards, which are discharged directly into water bodies from industrial wastewater without prior treatment. Therefore, a simple treatment method is needed to process liquid waste from the tofu industry to ensure that the quality meets established standards before disposal in order to prevent environmental contamination.Currently, the Moving Bed Biofilm Reactor (MBBR) method is becoming increasingly popular for wastewater treatment in both domestic and industrial applications. This method offers several advantages, including low energy consumption, no need for additional chemicals during operation, which avoids the generation of additional waste, and relatively simple operation and maintenance. In addition, MBBR does not require a large land area. Research shows that MBBR is effective in reducing concentrations of nitrogen compounds and organic compounds in wastewater. The highest removal efficiencies achieved are 92% for COD, 92% for TSS and 94% for NH3-N.

Abstract

Effective and efficient water treatment is needed to improve water quality. The content of iron (Fe) and manganese (Mn) compounds in water is a major problem that can affect health and interfere with human activities. One of the steps that can be taken to degrade manganese is oxidation using aeration. In this study, variations in the diameter of venturi aerators were used to determine the performance of venturi aeration in water treatment. The variation in diameter was set at 12mm, 10mm and 8mm sizes. Based on the results of the study, dissolved oxygen levels have increased over time. The highest increase in dissolved oxygen content was achieved with the 12 mm diameter variation with dissolved oxygen levels reaching 7.8 mg/litre within 60 minutes. a significant reduction in iron content of 92% with an iron content of less than 0.0567 mg/litre. The largest percentage decrease in manganese content occurred with the variation of the aerator vent hole diameter of 12 mm, which was 54% with an aeration time of 15 minutes. There is a fluctuation in the decrease in manganese content caused by the more difficult to oxidise properties of manganese.

Abstract

South Sumatra is a province with high agricultural productivity. One of the largest agricultural products is corn and coconut, which is quoted from the website of the Lampung Province Food Security, Food Crops and Horticulture Office in 2021, which states that South Sumatra Province is one of the 10 largest corn producing provinces in Indonesia. With this in mind, the researcher conducted a study using the silica content of corn cobs and coconut husk waste as raw material for the production of potassium silica fertilizer using the sol-gel method. The potassium silicate fertiliser was produced by reacting KOH with corncob ash and coconut husk ash, which were varied. This is because the independent variables used are the concentration of KOH (4M, 6M) and the composition ratio of corn cob ash and coconut shell ash (10:40, 20:30, 25:25, 30:20, 40:10). The final result gave the best sample with more coconut shell ash composition than corn cob ash and higher KOH concentration. The sample formed 12.7 grams of final product with potassium content of 8821 mg/L and water content of less than 1%. As for the silica content in 4:1 coconut shell ash, there is approximately 73.2% silica.

Abstract

The Sustainable Development Goals (SDGs), point 6, has the objective of ensuring access to clean water and sanitation. The planning of a drinking water treatment plant is an essential component of achieving Target 6.1, which aims to provide safe and affordable drinking water for all by 2030. However, the Pangalengan subdistrict in Bandung Regency is confronted with a significant challenge, as 56.67% of cattle farmers are engaged in the discharge of livestock waste into the Cisangkuy River. It is therefore imperative to plan the construction of a drinking water treatment plant in the Pangalengan subdistrict. The research method commences with a comparison of the results of raw water tests conducted on the Cisangkuy River, which are then contrasted with the stipulations set forth in Health Minister Regulation No. 2 of 2023. Subsequently, a population projection is conducted in order to ascertain the projected water demand. The projected water demand is 371.92 liters per second in 2032. Subsequently, the selection of treatment units is conducted using the Likert scale method. The analysis yielded the conclusion that the quality standards are exceeded by the parameters turbidity and coliform. The alternative units employed are the intake, barscreen, coagulation and flocculation, sedimentation, filtration, disinfection, and reservoir units.
