Abstract

Food waste management is a global challenge that encourages the application of the circular economy concept through resource reuse. Chicken eggshell waste has the potential to be used as a renewable source of calcium, while hydrothermal processing is a promising method for converting it into value-added products. This study aims to map the development of hydrothermal processing research on chicken eggshell waste through a bibliometric analysis of 75 Scopus-indexed publications from 2019 to 2024. The results of the analysis show that China is the country with the highest number of publications. Co-authorship analysis identified 27 collaborating authors, with Zhang, X., Yin, J., and Wang, I. as the main authors. The most dominant keywords were “hydroxyapatite,” “hydrothermal method,” and “calcium.” This study shows that hydrothermal research focuses on the development of calcium-based biomaterials and nanomaterials and opens up opportunities for further research on the sustainable use of chicken eggshell waste.

Abstract

The population of Bandung City in 2024 reached 2,579,837 people with a total daily waste generation of 546,151.49 tons/year. The largest composition of waste is domestic waste (household waste). The high volume of waste puts serious pressure on the Final Processing Site (TPA). As a form of commitment to achieving national waste management targets, the Bandung City government continues to encourage the implementation of the Reduce, Reuse, and Recycle (3R) approach. One solution from the implementation of 3R is the incineration of residual waste using a waste incinerator. However, the composition of waste greatly affects the quality of emissions produced. The content of organic materials, plastics, heavy metals, and water content in the waste can produce hazardous pollutants such as particulates, carbon monoxide (CO), nitrogen oxides (NOx), dioxins, and furans if the incineration process is not carried out optimally. Air quality monitoring in the surrounding area needs to be considered, given that the effluent from waste incineration in incinerators is dispersed into the ambient air using AERMOD software.

Abstract

Product quality is an important factor in the automotive industry, because defective products can reduce production efficiency, increase costs, and reduce customer satisfaction. This study aims to identify the dominant types of defects and analyze the main causes of defects in the Instrument Panel production process at PT. Industri Otomotif by applying the Seven Tools method. The research method uses a case study approach with data collection through direct observation, interviews, and production data documentation. The analytical tools used include check sheets, flowcharts, histograms, scatter diagrams, control charts, Pareto charts, and fishbone diagrams. The results show that there are four main types of defects, namely shot mold, bubble, burry effect mold broken, and discolor (striped), with the dominant defect being shot mold at 38.52%. Further analysis using the fishbone diagram revealed that the main causes of defects come from machine, method, material, and human factors. The application of the Seven Tools has proven effective in providing a comprehensive overview of production conditions and generating improvement recommendations that can reduce the level of defects, improve product quality, and reduce production costs.

This study aims to see the effectiveness of kopasanda leaf extract as a free radical scavenger in sunscreen formulations. Currently, the need for skin care is increasing, where the level of skin brightness is one indicator of skin health. Skin color when exposed to UV rays will change even if left to be exposed continuously which is worse can cause cancer. Kopasanda leaves are studied to contain ingredients rich in flavonoids such as polyphenol compounds that have a role as antioxidants in warding off free radicals. In proving this, it is necessary to test the antioxidant activity with the DPPH method, as well as apply it as a lotion product. Kopasanda leaf extract with the addition of ethanol solvent with varying concentrations of kopasanda leaf extract additives of 1%, 3%, 5%, and 7% with stirring times of 30 minutes, 60 minutes, and 90 minutes. The results of the study on antioxidant activity without adding a concentration of 0 were 124,845 ppm and the antioxidant activity with the addition of a concentration of 5% and 7% were 117,230 ppm and 114,201 ppm.

Abstract

Heavy metal pollution in river ecosystems has the potential to disrupt the environmental balance and endanger human health, thus requiring a study of metal content in water and sediment segments. This study aims to analyze the concentrations of cadmium (Cd), chromium (Cr), and copper (Cu) in river water and sediments and compare them with the quality standards set by Government Regulation No. 22 of 2021. Sampling was conducted purposively at several stations in the upper, middle, and lower reaches of the river, then analyzed using Atomic Absorption Spectrophotometry (AAS) after undergoing preparation and wet destruction processes. The results showed that the levels of Cd, Cr, and Cu in sediments were generally higher than in water, indicating the role of sediments as a medium for metal accumulation. At point 3, the concentration of Cu in the sediment exceeded the ISQC Low ANZECC threshold value of >65 mg/kg, while the Cr and Cu levels in the water exceeded the class 2 quality standards of >0.05 and >0.02 mg/L. Overall, the quality of river water and sediment is greatly influenced by industrial waste, thus requiring efforts to control sources of pollution and regular monitoring in the study area.

Abstract

Reinforced concrete (RC) jacketing is a universally recognized effective technique for strengthening and repairing structurally compromised columns. This paper integrates previous research to evaluate the effectiveness of RC jacketing in improving the axial and seismic performance of columns through external confinement. The literature review demonstrates that RC jacketing significantly improves the load-bearing capacity, ductility, and stiffness of columns. Key factors influencing performance are identified: surface preparation, use of mechanical connectors, adhesives, and the number of coated sides, with four-sided jacketing being particularly effective. The literature review also explores practical applications, such as partial jacketing at column corners and preload member jacketing, along with identifying their cost-effectiveness in economic terms compared to full renovation. Furthermore, innovative approaches such as the use of sustainable bamboo reinforcement and hybrid techniques combining jacketing with additional beams have the potential to improve efficiency and environmental sustainability. It can be demonstrated that RC jacketing has proven to be a reliable, economically and structurally viable solution for rehabilitation.

Abstract

Domestic wastewater management at the neighborhood scale remains a significant environmental challenge, particularly in areas with limited sanitation infrastructure. Pampang Village, Makassar City faces constraints related to the suboptimal performance of domestic wastewater treatment systems, which may degrade residential environmental quality and contaminate surrounding water bodies. Constructed wetlands (CW) have emerged as nature-based wastewater treatment technologies offering sustainable and locally adaptive sanitation alternatives. This study aims to examine the conceptual suitability of CW as a domestic wastewater treatment system at the neighborhood level in Pampang Village, Makassar City. The research method is based on a literature review and conceptual analysis of CW working principles, system types and characteristics, and their suitability in terms of technical, operational, environmental, and social aspects. The results indicate that CW demonstrate a high level of suitability for implementation at the neighborhood scale. Domestic wastewater with moderate organic loads allows CW to operate effectively through the integration of physical, chemical, and biological processes. Design flexibility, particularly in vertical-flow and hybrid systems, enhances adaptability to land limitations, while low energy requirements and operational simplicity support community-based implementation.

Abstract

Population growth and metropolitan activity in Cimahi City, with a population of 598,698 residents in 2024, and with a waste composition dominated by organic materials, have heightened the need for a more effective waste management system. Sarimukti Landfill, which serves as the regional disposal site for Greater Bandung, has exceeded its capacity, requiring compliance with disposal capacity limits within its service coverage. Given the limited land availability and high population density, optimizing existing waste management facilities has become the most relevant and feasible strategy. This study aims to formulate sustainable waste management strategies for Cimahi City by identifying strategic factors using the SOAR framework. Data were collected through semi-structured interviews and direct observations with stakeholders involved in waste management in Cimahi City. The SOAR approach was selected to explore strengths, opportunities, aspirations, and expected results, thereby producing a strategic mapping that emphasizes stakeholder collaboration. Based on the SOAR analysis, the Strength–Aspirations (SA) strategy demonstrates the greatest implementation potential, comprising efforts to strengthen waste-sorting literacy and practices, develop standardized SOPs, enhance inter-agency coordination, innovate volume-based financing schemes and digital service channels, and reorganize operational systems toward sustainability.

Abstract

Palangka Raya City is a developed urban area with significant traffic flow, especially on primary arterial roads connecting provinces and districts. This condition leads to a high potential for traffic accidents. Jekan Raya District, as one of the districts in Palangka Raya, had a population of 140,173 people in 2019, so the accident risk level in this area is quite high. Population density causes competition for space and limited access to road infrastructure, which exacerbates traffic problems and increases the risk of accidents. Geographic Information Systems (GIS) can be used as an alternative to analyze and generate maps of areas and accident-prone areas in Jekan Raya District. Based on calculations of accident and fatality rates on Jalan Tjilik Riwut, the average accident rate from 2018-2022 reached 7.22% with a fatality rate of 1.19% per 100 million vehicle trips. Several roads classified as black sites include Jalan Tjilik Riwut (181 incidents), Jalan G. Obos (58), Jalan RTA Milono (38), and others. This data serves as an important reference in managing locations prone to traffic accidents.
