Abstract

“X” garment industry’s Sewage Treatment Plant (STP) was built to treat domestic wastewater with an inflow capacity of 500 m3/day. The main principle of the STP technology is an attached growth process with Moving Bed Biofilm Reactor (MBBR) technology using biochip media. Wastewater treated at the STP must meet the water quality standards of Ministry of Environment and Forestry Regulation 68 of 2016 before being discharged into water bodies. Therefore, this research aimed to evaluate the “X” garment industry’s STP performance. Wastewater sampling was carried out at the inlet and outlet of STP. Water quality parameters analyzed included pH, BOD, COD, TSS, oil and grease, ammonia, and total coliforms. The removal efficiency value is obtained from the calculation of sampling results. The analysis showed that all treated water parameters met the water quality standards throughout the research period. Hence, the average removal efficiency value at the STP for each parameter was above 90%.

Abstract

The river, a vital resource for agricultural, industrial, and domestic use, faces pollution pressures from anthropogenic activities. This study examines the water quality parameters of the Kemambang River in Sidoarjo, East Java, within the context of the One-Health Framework, emphasizing the interconnectedness of environmental, human, and animal health. Sampling conducted at three distinct points along the river revealed spatial variability in key parameters such as Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO), temperature, and oil and grease content. Analysis showed that while pH remained within acceptable limits, BOD and oil and grease levels exceeded regulatory standards, particularly downstream, where domestic and agricultural runoff contributed to oxygen depletion. Spearman correlation analysis highlighted strong positive correlations between TSS, COD, and oil and grease, while BOD and COD were negatively correlated with DO, underscoring the impact of pollutants on oxygen dynamics. These findings demonstrate how industrial and domestic activities compromise the river's ecological health, impacting human and aquatic systems. By adopting the One-Health Framework, this study provides a holistic perspective on water quality challenges, offering insights for targeted interventions and sustainable management practices.

Abstract

Rapid urbanization, population growth, and climate change have escalated the demand for water resources, significantly widening the gap between water supply and demand. Among various strategies for water resource management, rainwater harvesting emerges as a sustainable and efficient solution. This study evaluates the rooftop rainwater harvesting potential of Bharathiar University Campus, Coimbatore, utilizing its 96,839 m² rooftop area as the catchment. Water demand for entire university was calculated by combining the supply of water to the use of all buildings, research laboratories and gardening from university water supply unit. The total rooftop rainwater potential was calculated combining total catchment area (m2), amount of rainfall (mm) and runoff coefficient. The analysis revealed that the campus rooftops could annually harvest 4,90,28,274 liters of rainwater. This harvested water has the potential to meet approximately one-fourth of the campus’s total water demand (13,36,91,625 liters), providing a viable strategy to alleviate water scarcity while reducing dependency on external water sources and groundwater extraction.

Abstract

Oil contamination in the soil might cause degradation on the quality of the soil, which becomes a problem for the environment and the organisms in it, especially the plants. The plants will be unable to grow and develop properly in the degraded soil, which will give a severe negative impact to agricultural sector. Biostimulation can be a good solution in solving soil degradation problem, utilizing microorganisms and biostimulant. The objective of this study is to discover the potential of chicken manure as biostimulant for biostimulation process in the removal of total petroleum hidrocarbon (TPH) as one of the main properties in oil contaminant. In this study, the chicken manure as biostimulant were being mixed with the oil contaminated soil (400 gr), with variation of weight; W1= 50; W2= 100; W3= 150; and W4= 200 gr. Biostimulation process were being observed and analyzed every 7 days for 21 days, and being compared with the soil without biostimulant addition (control). The result shown that biostimulation process using chicken manure in this study can remove up to 66.67% of TPH, from 6% of to 2% (W4 for 21 days), but still unable to fulfill the quality standard given, which is 1%. Based on the result of this research, it can be concluded that biostimulation using chicken manure as biostimulant can be utilized to remove TPH from oil contaminated soil, hence still need improvement to perform better.

Abstract

Lhokseumawe City faces significant clean water distribution challenges due to increasing demand from population and economic growth. This study aimed to identify and evaluate the performance of the existing water distribution network using WaterCAD V8i. The methodology involved projecting water demand until 2033 based on 10 years of population data and conducting a hydraulic simulation of the current pipeline system. The simulation results showed that the 2023 clean water demand was 84.5 liters per second, with projections showing a significant increase by 2033. The analysis identified critical operational issues, including backflow in pipe segments P-230 and P-235 and extreme pressure loss gradients in others, with segment P-276 reaching 275 psi during peak hours. It was concluded that the network requires optimization to meet future demand efficiently. Improvement recommendations include replacing critical pipes, resetting valves, and adding pressure regulators to optimize flow.

Abstract

Fire can occur if three main elements are met, namely heat, oxygen, and fuel or it is called the fire triangle. Risks arising from fire incidents can be minimized by a fire protection system and the reliability of building safety systems. To ensure that the two systems run optimally, an evaluation and examination are needed on the existing conditions based on the applicable safety technical standards. This study aims to determine the existing condition of the applied fire protection system and to determine the reliability of the building safety system in the Ar-Raniry Multifunctional Laboratory Building. This research was conducted using a quantitative descriptive method. Research data collection was carried out using observation and interview methods. The observation method for existing conditions was carried out using a checklist compiled based on the Indonesian Minister Public Works’ Regulation Number 26/PRT/M/2008 of 2008 for fire protection systems and fire protection code from the National Standardization Agency of Indonesia Number Pd-T-11-2005-C on the reliability of building safety systems. The results show that the fire protection system in the UIN Ar-Raniry Multifunction Laboratory building was in the Enough category, with a value of 3.25. This is due to the absence of several active fire protection instruments such as fire extinguishers, sprinklers, and hydrants. Addionally, from the results of the reliability of the building safety system for the UIN Ar-Raniry Multifunction Laboratory building, it is in the Enough category with a value of 63.02. This is caused by the absence of emergency lighting and water sources as a source of hydrant water.

Abstract

Generally, the volume of water used for wudu varies for each person, with an average of 6 liters per person per time, depending on the habit of how one opens the tap and the water flow rate. However, according to hadith, the Prophet Muhammad Saw performed wudu using only one mud of water (625 milliliters). Water conservation during wudu can be achieved by reducing the amount of water discharged from the tap. In this study, an automatic wudu faucet prototype was designed, equipped with infrared sensors, a buzzer, ultrasonic technology, and controlled by an Arduino Uno microcontroller. In this system, the faucet will only open when there is an object or a hand/foot beneath it and will close when no object is detected anymore. Additionally, the system will produce a sound indicating that an object is approaching within a distance of 10 cm. This prototype is able to increase the efficiency of water usage during wudu by 67%. The average water usage for wudu using a manual faucet by the subjects was found to be 4.86 liters per person per time. After using the automatic wudu faucet prototype, the average water usage was reduced to 1.624 liters per person per time. Water conservation, even in small activities like wudu, can contribute to preserving water resources and ensuring their availability on Earth.
