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

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

Coconut leaf waste is a type of waste that contains a good enough calorific value to be used as raw material for biomass pellets. The minimum standard calorific value of biomass in Indonesia according to SNI 8675:2018 is 16.05 MJ/kg. Meanwhile, based on the research results, the calorific value of coconut leaf waste has a value of 13.34 MJ/kg. The way that can be applied to increase the calorific value is by biodrying. This study aimed to determine the effectiveness of the biodrying process in processing coconut leaf waste. This study use bioactivators in the form of tempe yeast, baker's yeast, and tapai yeast. Mass loss and moisture reduction can be achieved, respectively, 8.25-17.62% and 62.4-65.6%. The calorific value can reach the minimum standard after seven days of processing with a value of 17,995-18,623 MJ/kg.

Abstract

To better manage Jakarta's domestic wastewater, the DKI Jakarta Provincial Government commissioned the construction of Domestic Wastewater Treatment Plants (WWTP) in multiple locations across the city. After the results of the measurements have been determined, engineering work needs to order to address the numerous parameters more than excesses of the quality in addition, there. This study intends to develop a vertical flow CW design as an additional treatment for the DKI Jakarta Environmental Service Dormitory Communal Domestic WWTP as a recommendation for improvement so that the quality of treated water can meet domestic wastewater quality standards. This study aims to ensure that the quality of treated water can meet domestic wastewater quality standards. This redesign makes use of a variety of data sources, including primary data as well as secondary data. The necessary information is the quantity of constable water consumption and the quality of the domestic wastewater produced within the environment of the DKI Jakarta DLH Dormitory. Through a network of pipelines, wastewater from activities such as bathing and using the latrines is transported directly to the WWTP. During this time, water from activities such as washing and runoff caused by rain will enter various drainage channels to the receiving water body, the Ciliwung River. The length of the CW at WWTP 1 is 6.718 meters, and its width is 3.35 meters. Following more in-depth processing of the available data, it was discovered that the existing outlet wastewater had a low C/N ratio. When creating wetlands in the field using artificial CW, the discharge that flows into the wetland and the release that flows out of the wetland is not the same. The amount can either be decreased or increased according to the current circumstances. This needs to be considered for the presence of water in the swamp system to be managed. After being processed with VFCW, it was discovered that the total BOD value of the effluent produced was less than 30 mg/L. This suggests that the processing of VFCW can conform to the requirements of PermenLHK No. 68/2016, which is concerned with the Quality Standards for Domestic Wastewater. The ammonium-nitrogen value by comparing the molar mass value to NH3. As a result, WWTP locations 1, 2, and 3 have all achieved the required quality. The NH4 value, on the other hand, has not been able to meet the quality standard of PermenLHK No. 68/2016 concerning Domestic Wastewater Quality Standards. This is because the ammonia concentration from Domestic Communal WWTP 4 is so high. As a solution to this problem, WWTP 4 will be upgraded from four plants per square meter (ppm) to five plants per sq m (ppm), hoping to improve the rate at which plants absorb nutrients. The removal of ammonia using VFCW can range anywhere from 34 - 95 percent. Keywords: Domestic Wastewater, Planning, Constructed Wetland, WWTP

Abstract

The deterioration of air quality in Jakarta, Indonesia, has become a growing public concern. Exposure to polluted air is known to be hazardous to public health, particularly for sensitive groups such as elderly citizens. PM2.5 (fine particulate matter with an aerodynamic diameter 2.5 μm) is among the most dangerous pollutants commonly found in urban atmospheres. This study assessed the relationship between atmospheric PM2.5 exposure and health-related symptoms among elderly citizens living in Jakarta, Indonesia. PM2.5 concentrations in ambient air were measured using a High Volume Air Sampler with a PM2.5 size-selective inlet for a week in an outdoor location at a nursing home during the Covid-19 pandemic. Health-related symptoms of elderly citizens were collected using a systematic interview method. Both sets of data were collected simultaneously for cross-sectional analysis. Based on the sampling data, PM2.5 concentrations in the area ranged from 15.4 to 42.9 μg/Nm3 (at standard conditions); the Air Pollution Standard Index ranged from 49.9 to 84.3; and the Air Quality Index was moderate for 6 out of 7 (85.7%) days. Results showed that sensitive groups, including elderly citizens, are very likely to be negatively affected by polluted air. The chi-square test results imply that emerging health-related symptoms are significantly affected by elderly citizen characteristics, such as age, gender, smoking habit, and residence time, rather than by the Air Quality Index.

Abstract

The wastewater treatment plant (WWTP) in the Nusa Dua area has implemented a stabilization pond to reduce organic matter and nutrients. Because it has been operating since 1980, it is necessary to evaluate the existing conditions. The aim of this study was to determine the percentage of organic and nutrient reduction from the WWTP system. Organic removal in the form of BOD and COD parameters were 71.84% and 75.11%, respectively. Meanwhile, nutrient parameters in the form of NH3-N, TN, and TP have a percentage of 83.64%; 59.41%, and -375.81%, respectively. TP is the only parameter that has increased, causing a problem which is caused by the explosion of algae population in the reservoir. TP allowance should be a concern in choosing advanced treatment.
