Abstract

Air pollution is the condition of air that is contaminated by the presence of materials, substances or polluting components. One of the causes of air pollution is the combustion or inseneration process because the residue of the process can be released into the air. Based on ISPU, there are five main pollutants, namely: carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOX), surface ozone (O3), and dust particles (PM10). This study was conducted to reduce the emission of gases. The use of modified cyclone with adsorbent pipe tube from cocoa husk can increase the efficiency of combustion results with adsorption pipe tube modified cyclone. From the results of the study it was found that emissions from incineration can be controlled with APPU in the form of a cyclone. The use of cyclone alone can reduce NOX and CO levels with a reduction in NOX emissions to 53% and CO to 96%. Both emission reductions are in line with the quality standards. However, the use of adsorption pipe tubes showed better efficiency and effectiveness.

Abstract

Palm oil mill effluent (POME) is the main waste generated from the palm oil industry. LCPKS has a COD level of 57,000-60,400 mg/L. High levels of COD can harm the environment. LCPKS treatment techniques generally use a combination of anaerobic and aerobic waste treatment methods. The anaerobic process has been conducted using a UASB-HCPB reactor. But, the COD levels of anaerobic results have not reached the quality standards so that further processing is needed. Microalgae have the potential to reduce contaminant levels in wastewater. Chlorella vulgaris microalgae is a microalgae that is widely used in wastewater treatment. This study utilized Chorella vulgaris in reducing the COD levels of the effluent of the UASB-HCPB biogas fermentor with variations in lighting intensity and variations in the ratio of effluent to microalgae. It was found that the lighting intensity of light:dark (24:0) hours provided optimal microalgae growth so as to provide the best COD reduction with a COD reduction efficiency of 87.5%. The ratio of microalgae to effluent of 1000 mL: 500 mL showed the best COD reduction with an efficiency of 93.75%.

Abstract

The increase in organic waste generation in Indonesia is driving the need for more sustainable waste management innovations, including through the bioconversion of maggots as an alternative protein source. However, at a business scale like Ratna's Black Soldier Fly (BSF), the maggot drying process remains a major obstacle because conventional methods produce inconsistent quality, require long drying times, and are energy-intensive. A community service project titled ECO-WAVE MAG was introduced to address this issue by implementing a microwave dryer as an appropriate technology. Activities included field surveys, designing and modifying the drying system, technical testing on fresh maggots with a moisture content of around 70 percent, and providing training and operational assistance to partners. Test results showed that the microwave dryer was able to reduce drying time by up to 70 percent, produce a stable final moisture content of 8–10 percent, and maintain the homogeneity and nutritional quality of the dried maggots. This technology also proved to be more energy efficient and able to increase production capacity and product shelf life.
