Abstract

The coronavirus disease 2019 (COVID-19) shifts the characteristics of municipal waste. This paper aims to provide an overview of trends, impacts, and management during the COVID-19 pandemic globally. The increase in the generation of plastic waste and infectious waste is a new challenge during the COVID-19 pandemic. It was found that the emergence of plastic waste due to the consumption of food delivery becomes an issue in several countries. Despite the increment of plastic waste generation, the mass layoffs contributed to the decrease in the total urban waste generation in general. In addition to plastic waste, a surge of infectious waste from health facilities and household waste originating from residents infected with the SARS-COV-2 virus was observed. This infectious wastewater potentially leads to environmental disturbances to the rivers and oceans. To tackle global environmental concerns, sustainable waste management is required especially in the development of biodegradable personal protective equipment.

Abstract

The potential for the use of coconut pulp as biodiesel fuel in Indonesia is very large because Indonesia is one of the largest coconut producing countries in the world. One of the conversion methods used to convert coconut pulp into biodiesel is the transesterification method using various catalysts. Based on several literature studies conducted, the yield produced using a CaO catalyst is 96.43% and using a KOH catalyst can reach up to 98.23% with the help of a microwave. The results of a survey that has been conducted on 30 grated coconut traders in various markets, the average coconut pulp produced every day is 20 kg/seller/day. The potential of biodiesel produced from the average amount of coconut dregs can reach up to 3.04 L using a KOH catalyst.

Abstract

Microalgae has emerged as a promising approach for removing substrate and nutrient from wastewater with the concomitant biofuel production. The substrate and nutrient removal are influenced by several factors such as C/N ratio, F/M ratio, pH, and DO. This study aims to determine the efficiency of substrate and nutrient removal with the growth rates of microalgae and biomass by varying the addition of aeration and substrate. Intermittently aerated reactors were used with the flow rate of 14 L/minute. The batch reactors were prepared by adding glucose substrate of 50 mg/L (Ra0A), 100 mg/L (Ra0B), and 150 mg/L (Ra0C) without aeration; 50 mg/L (Ra12A), 100 mg/L (Ra12B), and 150 mg/L (Ra12C) with 12-hour aeration, and 50 mg/L (Ra24A), 100 mg/L (Ra24B), and 150 mg/L (Ra24C) with 24-hour aeration. The substrate removal, expressed as chemical oxygen demand (COD) in the reactor with aeration, showed the efficiency of 73.88% ± 2.05 (12-hour aeration), 75.2% ± 3.97 (24hours aeration), and 69.86% ± 5.69(without aeration). Nutrient removal as ammonia-N (NH3-N) gave high removal value of 98.3% ± 0.11 and the removal of nutrient as phosphate (PO3-4) showed the efficiency of 54.3% ± 0.1. The growth rate of microalgae and biomass exhibited the highest value in Ra24C reactor with the values of 0.0229/day and 0.1295/day, respectively. The pH values indicated a shift from normal to alkaline while DO values increased by the addition of 12 and 24-hour aeration.

Abstract

The wastewater treatment plant (WWTP) at the Universitas Pertamina area is one of the campus's efforts to reduce the environmental impact of wastewater production. The processed WWTP can be processed into ready-to-drink water as an effort to reduce plastic waste. This plastic waste is usually produced by the consumption of mineral water products. The availability of ready-to-drink water in the campus complex is expected to increase the interest of campus residents to use tumblers and reduce the generation of plastic waste as well as university proactive efforts. The purpose of this study was to analyze the units needed to process WWTP effluent into ready-to-drink water by looking at various alternatives. This study uses the analytical hierarchy process (AHP) in determining the best alternative. The units required for each alternative are equalization tub, slow sand filter, and disinfection. Meanwhile, for processing, there are three alternatives, namely microfiltration (MF), ultrafiltration (UF), and combined microfiltration – ultra-filtration (MF-UF). The selection of these alternatives was adjusted to the criteria of cost, required membrane area, flux recovery after backwashing, and the effectiveness of total coliform removal. MF filtration technology is the largest weight, which is 0.381. Where the use of MF in the Universitas Pertamina area is cheaper and requires better area than UF and MF-UF technology.

Abstract

Small scale business / Usaha Skala Kecil (USK) X currently does not have a batik wastewater treatment unit. This condition causes the possibility of contamination to water bodies. USK X wastewater treatment applications' planning needs to be carried out sustainably, namely by reusing water. The process units needed in this planning are the sequencing batch reactor (SBR) and constructed wetlands. The effluent of textile wastewater with this system for parameters BOD, COD, TSS, sulfide, total oil & fat, and color were 0.13 mg/L; 106.5 mg/L; 2.4 mg/L; 0.036 mg/L; 0.07 mg/L; and 90.67 PtCo, respectively. The dimensions of the SBR unit required are 0.75 x 0.6 x 1 m. Modification of the SBR unit uses an ozone generator to produce ozone gas which functions as oxidation of organic pollutants and colors in batik waste. After processing in the SBR unit, it is carried out using a constructed wetland with 2.56 m2.

Abstract

Excessive water consumption to meet water needs has changed aquatic water quality and quantity. Focus on domestic wastewater treatment via built wetlands. Disinfection protects humans against disease-causing viruses, bacteria, and protozoan parasites in wastewater. This study planned the disinfection of artificial wetland wastewater to fulfill microbiological criteria. From the examined data, each unit's design criteria and disinfection effectiveness for the created wetland outlet in the WWTP unit will be discussed. The created wetland must process 8696 cfu/100mL of fecal coliform. Despite good processing efficiency, 94% of fecal coliforms do not fulfill quality criteria. WWTP's wetland emits 8.011 mg/L of Ammonia. 90% chlorine costs Rp. 35,000/kg on the market. Total disinfection costs are rough Rp. 1,018,210.73. Water quality, lamp output power, and exposure distance affect lamp intensity. The lamp's electric power controls the beam's intensity; the more power, the more emission. The emitted power isn't equal to the lamp's electric power. According to the state electricity provider, families with a 900VA power limit will pay Rp. 1,352/kWh in July-September 2021. Nine 30-W bulbs irradiate bacteria. The lights will run for 24 hours non-stop. Hence the monthly electricity usage is 194.4 kWh or Rp 262.829.00.

Abstract

Cement is a prominent Indonesian industry. Industrial fuel needs are growing. In Indonesia, biomass is an essential natural resource with a variety of primary products such as fiber, wood, oil, food, and others that are utilized domestically and exported to generate foreign cash. This study compares fly ash and bottom ash as alternative fuel feedstock materials from the cement industry. This study uses cement industry data from East Java. As, Cd, Cr, Pb, Hg, TI, Sb, Co, Ni, Cu, V, Zn, Se, and Sn for bottom ash and fly ash quality data are employed. The investigation followed a paired t-test to compare ash types based on metal characteristics, then an ANOVA post-test to establish the significance of bottom ash and fly ash values. The paired t-test on two types of ash showed a 0.103 difference. ANOVA shows that ash kinds differ significantly. Bottom ash and fly ash have different qualities. Hence their management requires various approaches. This treatment utilizes bottom ash. For fly ash, the quality-related parameters must be lowered.

Abstract

Natural rubber is one of the agricultural products in exceptionally high demand for industrial materials. In Indonesia, rubber is a major plantation crop grown all across the country. This research seeks to use the LCA technique, but its primary objective is to examine the consequences of the crumb rubber industry. Using sulfuric acid causes the emission of roughly 11,94705 kg equivalent of the gas sulfur dioxide into the environment. In contrast, using isoprene as a base material causes the emission of approximately 1090 kg equivalent to the gas carbon dioxide. Coal-derived energy accounts for up to 719,748 MJ, or 199,930 kWh, and is the critical focus in the quest for alternative energies. Because the macerator, creeper, hammer mill, and drying machine take 199.93-kWh of electricity to operate.
