Abstract

Clean water is a fundamental need for coastal and small island communities in Indonesia due to limited freshwater sources and high groundwater salinity caused by seawater intrusion. This study aims to design an innovative prototype of a solar-based seawater distillation technology as a low-cost and environmentally friendly solution. Technology adopts evaporation and condensation principles to convert seawater into clean water that meets quality standards. The distillation device is constructed using simple, corrosion-resistant materials, such as transparent glass, utilizing sunlight as the primary energy source, with condensed water droplets collected through an outlet pipe into a clean-water reservoir. The results demonstrate that the seawater distillation process is highly effective in separating seawater into clean water free from salt content, microorganisms, and impurities. The distillation process can reduce the salt content of seawater by up to 99% ppt and the pH level to 7.5. In addition, the hardness level (66.58 mg/L), nitrate (NO3⁻) (1.10 mg/L), nitrite (NO2⁻) (0.026 mg/L), iron (Fe) (<0.0034 mg/L), and microbiology (MPN Coliform and APM E. Coli = 0 MPN/CFU/100 mL) also decreased in accordance with the standard quality standards for clean water. The cost efficiency and ease of implementation of this technology offer a promising solution for clean water provision, supporting the achievement of sustainable development goals related to clean water and sanitation.

Abstract

The high number of work accidents in construction projects shows that there is still a lack of understanding and application related to occupational safety and health (OSH), so that every party involved in project implementation needs to understand and apply OSH to minimize the occurrence of work accidents. This study aims to identify OSH in the construction project of the Rectorate building of Universitas Muhammadiyah Kendari (UMKendari) to provide educational office facilities as a center for management and academic services based on high technology. The research method is to identify potential hazards that cause work accidents and apply OHS standards using the Hazard Identification Risk Assessment and Determining Control (HIRADC) method. Specifically, this research identifies hazards, assesses risk levels, and provides risk control efforts in the construction of the Rectorate building. Based on this research, 4 stages of construction were obtained, namely preliminary work, structural work, architectural work, and mechanical, electrical, and plumbing (MEP) work. There are 112 potential hazards with 13 potential hazards are at low risk level, 36 potential hazards are moderate, 57 potential hazards are high, and 6 potential hazards are very high. We suggest for OHS implementation where potential risks and assessments are needed to reduce work accidents by administrative control, elimination, substitution, control techniques, and personal protective equipment (PPE).

Abstract

This research study focus on Utilization of candlenut shell carbon adsorbent for separating oil and fat in restaurant wastewater. The problem in this study is the oil and fat in restaurant wastewater that has passed the domestic wastewater standard of 6.31 mg/L. The objectives of this research are to investigate the variation in mass of candllenut shell carbon adsorbent in separating oil and fat in restaurant wastewater and the effectiveness of canddlenut shell carbon adsorbent in separating oil and fat in restaurant wastewater. The method used with the use of a simple filtering device model with a direct flow of waste water by canddlenut shell carbon adsorbnet. The results of the study showed that at mass variations 25 grams had a high efficiency value with an efficiency of 17,43% and a kinetic value of the adsorption of left-handed carbon chewing k value of 1,2.10-3 min-1. The implications of this study are that the level of candllenut shell carbon effectiveness in separating oil and fat in the waste water of the food facilities is still less effective.

Abstract

This study investigates the possibility of using corn husk as an adsorbent media to reduce fat and oil levels in wastewater from restaurants. Restaurant activities produce wastewater containing oil and fat from cooking and food processing activities that require treatment before being discharged directly into the environment, including oil and fat parameters. The purpose of the study was to analyze the ability of corn husk to absorb restaurant wastewater contaminants. Adsorption is the approach used in this study. Corn husk is one type of adsorbent used. Corn husk contains 44.08% cellulose which allows corn husk to act as an adsorbent. The adsorption process was carried out using variations in contact time and adsorbent weight. The oil and fat content was analyzed using the gavimetric extraction method. The results showed that the best oil and fat removal capacity was obtained at a contact time of 80 minutes with an adsorbent weight of 12.091 g at 5.58 mg/L with an absorption efficiency of 8.82%. The findings of this study are expected to encourage more research in this field, such as increasing adsorption efficiency, developing other adsorption technologies based on agricultural waste, or adsorption applications in other fields such as wastewater treatment and environmental remediation.

Abstract

Tofu industry wastewater contains high levels of organic pollutants, and its direct discharge into water bodies can cause significant environmental damage. Phytoremediation using water spinach (Ipomoea aquatica) offers a simple, low-cost, and eco-friendly method for treating such wastewater. This study aims to analyze changes in BOD, COD, TDS, and TSS levels in tofu wastewater before and after phytoremediation using water spinach. The research involved the preparation of growth media and the collection of tofu wastewater samples, followed by an 11-day phytoremediation process. The treatments varied based on plant biomass (200 grams and 400 grams) and plant age (25 days and 40 days). The most effective treatment was achieved using 400 grams of 40-day-old water spinach, which reduced TSS levels by 23.07% and TDS levels by 12.1%. However, the phytoremediation process in this study was not effective in reducing BOD and COD concentrations.

Abstract

Phytoremediation offers an environmentally friendly and cost-effective approach to mitigate heavy metal pollution by utilizing plants capable of absorbing and accumulating contaminants. This study explores the phytoremediation potential of Bajo starfruit (Sarcotheca celebica Veldk.) to absorb Ni from contaminated post-mining soil. This research aims to assess the absorption capacity of Sarcotheca celebica Veldk. for Ni and evaluate its feasibility as a phytoremediator. The Ni concentration in the soil was measured before and after planting to determine the reduction level attributable to the plant. Initial measurements showed a total Ni concentration of 0.32% in the soil. After a designated growing period, during which the plant entered the vegetative growth phase, the Ni concentration decreased to 0.29%, indicating an absorption capacity of 0.03%. The potential application of Sarcotheca celebica Veldk. as a native phytoremediation agent in sustainable post-mining land restoration programs. Its adaptation to local environmental conditions further supports its use in ecological rehabilitation strategies aimed at restoring the functionality of degraded ecosystems.

Abstract

In processing leachate, various biological processing processes have been carried out, however processing is needed to reduce inorganic content such as heavy metals in leachate water. Electrocoagulation is an alternative liquid waste treatment that uses the principles of electrolysis, coagulation and flocculation. The aim of the research is to analyze the effect of electrical voltage using aluminum electrodes on reducing the concentration of Fe and Cu metals in leachate water, then calculate the efficiency of reducing Fe and Cu metals from each electrical voltage treatment given in this study, namely 6, 12 and 18 volts with a contact time of 60 minutes. The method used in this research is quantitative, experimental on a laboratory scale. The research results showed that the optimum metal content reduction reached 0.0288 mg/L and 0.0086 mg/L with an efficiency of 97.75% and 82.05% for Fe and Cu parameters respectively at a treatment voltage of 18 volts. These results show that the leachate treatment process using electrocoagulation techniques has great efficiency.
