Abstract

The increasing interest of consumers in paving blocks because the construction of paving block pavements is environmentally friendly where paving blocks are very good at helping to conserve groundwater, faster implementation, easy installation and maintenance, have a variety of shapes that add aesthetic value, and the price is easily affordable. The purpose of this study was to determine the effect of adding Polypropylene plastic (PP) pellets on the compressive strength of paving blocks and to determine the effect of adding Polypropylene plastic (PP) pellets on the water absorption of paving blocks. This research method uses an experimental method carried out in the laboratory of structures and materials, Muhammadiyah University of Parepare from July to September 2024. The results of this study indicate that the sutittusi of polypropylene plastic pellets affects the compressive strength of paving blocks. The compressive strength values of paving blocks at 28 days of curing age are 35.583 Mpa, 34.500 Mpa, 33.833 Mpa, and 33.417 Mpa for each variation of 0%, 2%, 5%, and 7%. So by looking at the results obtained above, the higher the percentage of polypropylene plastic pellet substitution, the lower the compressive strength value. While the water absorption value of paving blocks shows that the substitution of polypropylene plastic pellets affects the water absorption of paving blocks. Variations of 0%, 2%, 5%, and 7% are respectively 4.4%, 4.6%, 4.8%, and 5.2%. So by looking at the results obtained above, the higher the percentage of polypropylene plastic pellet substitution, the higher the water absorption.

Abstract

Labor productivity in the construction industry plays a crucial role in project success, particularly in terms of efficiency, cost, and completion time. However, the sector faces persistent challenges in improving productivity due to various factors, such as workforce skills, project management, rapid technological changes, and strict safety regulations. This study aims to identify the dominant factors influencing construction labor productivity using a Systematic Literature Review (SLR) approach. By analyzing 100 scholarly articles from indexed international journals, data synthesis was carried out based on the frequency of factor occurrences in the literature. The findings indicate that communication between project management and workers is the most dominant factor, appearing in 82 references. This is followed by work experience (81 references) and supervisor experience (77 references), highlighting how expertise and leadership at project sites significantly influence workforce efficiency. Additionally, these factors are categorized into ten main groups, with Site Operations & Management being the most influential category (11.93%), followed by Motivation (11.81%) and Construction Workforce (11.57%). Other factors, such as design changes, material quality, and weather conditions, also contribute to productivity, albeit with lower frequencies. These findings underscore the importance of effective project management, clear communication, and workforce experience in enhancing productivity at construction. Nevertheless, the results of this study may not fully apply to all types of projects due to differences in location and project conditions. Therefore, further research is needed to explore the impact of other factors, such as technology and regulations, on improving labor productivity in the construction sector.

Abstract

Soil liquefaction is important in geotechnical engineering, particularly in seismically active areas like Indonesia and New Zealand. With an emphasis on publications written by researchers from Indonesia and New Zealand between 2015 - 2025, This research is a bibliometric analysis that uses data from the Scopus database and the VOS viewer application to assist in interpreting the gathered bibliometric data. The author from New Zealand (Misko Cubrinovski) seems to be the most productive in researching and writing related to soil liquefaction, with 48 articles. Authors from Indonesia are relatively more evenly distributed, with 10-20 articles dominated by Sito Ismanti, Lindung Zalbuin Mase, and Teuku Faisal Fathani. In addition, compared to Indonesian institutions, New Zealand institutions are more likely to collaborate with external parties such as the United States (University of California, University of Texas, University of Washington, etc.), enabling them to obtain greater funding to encourage research productivity. The research map used Scopus RIS data showing three clusters: red (general liquefaction terms), blue (New Zealand-focused, e.g., CPT and shear waves), and green (Indonesia-focused, e.g., seismic response). Minor clusters (purple, yellow) link related topics.

Abstract

This study explores the revitalization of Dang Anom Park in Batam City through a sustainable cultural approach that integrates local identity, ecological sensitivity, and inclusive urban design. Rapid infrastructure-driven development in Batam has led to the neglect of public spaces, raising concerns over the loss of urban identity and diminished community interaction. The research aims to address this gap by developing a design strategy that reconnects cultural values with spatial functionality. Employing a qualitative descriptive method, the study includes literature review, field observations, and a SWOT analysis to assess the site’s conditions and potential. The proposed design is guided by three principles: sustainable nature, interactive public space, and accessibility for the elderly and disabled. Design interventions include strategic vegetation to mitigate pollution, cultural elements to enhance identity, and inclusive facilities to support diverse community engagement. The masterplan reimagines the park as an environmentally responsive and socially vibrant public space. The findings demonstrate that culturally grounded design can restore vitality to underused spaces while reinforcing urban identity. While the study offers a valuable conceptual framework, it is limited by its qualitative scope and single-site focus. Future research should incorporate community participation, implementation trials, and broader comparative studies across similar urban contexts. This research contributes to the discourse on sustainable urban development by offering a replicable model for culturally responsive park revitalization in rapidly urbanizing cities.

Abstract

Batam City experienced increased congestion on several main roads, especially in the Hang Nadim Airport area. To overcome this, the government made changes to the road master plan. After the masterplan changes, the road capacity increased from 2,944.92 pcu/hour to 7,438.2 pcu/hour. Traffic volume from the Airport-Nagoya direction was recorded at 3,111.1 pcu/hour and from the Nagoya-Nongsa direction at 2,415.2 pcu/hour. The study was only conducted in areas with frequently passed traffic volume capacity, namely the Airport-Nagoya direction and the Nagoya-Nongsa direction. The evaluation was performed using indicators of capacity, traffic volume, and road service level. These results provide an important basis for more adaptive airport transportation planning in the future.

Abstract

Slope stability in nickel laterite mines is critically influenced by the distinct geotechnical properties of limonite and saprolite weathering profiles. These materials, prevalent in tropical mining regions, exhibit significantly different responses to hydrological and mechanical stresses, necessitating detailed stability assessments for safe mine operations. This study combines field investigations, laboratory testing, and Limit Equilibrium Method (LEM) analysis to evaluate slope stability. Geotechnical parameters were determined through standardized tests and slope stability analyses examined both single-slope (40°-60° angles) and overall-slope configurations with varying bench geometries (widths 3-5m, angles 29°-60°). The analysis demonstrated: (1) Safety factors (SF) decreased 25-30% as slope angles increased from 40° to 60°, with limonite (SF=2.8-2.1) consistently outperforming saprolite (SF=2.4-1.9); (2) Bench width significantly influenced stability, with 5m widths improving SF by 15-20% compared to 3m widths; (3) Optimal stability (SF=1.85) was achieved with gentler geometries (29° slope, 40° bench, 5m width), while steeper configurations approached critical conditions (SF=1.22). The study provides critical insights for designing stable slopes in nickel laterite mines, emphasizing: (1) material-specific slope angles, (2) wider bench designs, and (3) integrated geotechnical-LEM approaches. These findings directly address operational challenges in tropical mining environments, offering practical solutions to enhance safety while maintaining productivity. The methodology establishes a replicable framework for slope stability assessment in weathered geological profiles.

Abstract

The production of cement, as the primary material in concrete manufacturing, significantly contributes to global carbon emissions. To mitigate this impact, one of the solutions being developed is the use of natural or artificial pozzolanic materials as partial substitutes for cement. Rice Husk Ash (RHA) is an agricultural waste rich in amorphous silica and holds great potential as a local pozzolanic material in Indonesia. The review results show that using RHA in the range of 10–20% can enhance the compressive strength and improve concrete resistance to aggressive environments. The effectiveness of RHA is highly influenced by the fineness of its particles and the combustion process. Considering its availability and environmental impact, RHA has great potential as an eco-friendly material solution for construction based on local resources.

Abstract

Building maintenance and care are essential responsibilities that must be managed effectively to ensure optimal building performance and appearance. One of the key aspects of building maintenance is painting. Painting not only enhances the visual appeal of a building but also contributes to its overall preservation. However, paint has a limited lifespan and resistance to fading or deterioration. The decline in paint quality often occurs before reaching its expected durability due to various environmental and social factors such as humidity, rainfall, wind, dust, sunlight, and human activity. Therefore, understanding the service life of exterior paint is crucial to ensure timely maintenance and upkeep of the building. A study was conducted on the existing exterior paint of the Bencoolen Mall building, located at Jl. Pariwisata No. 01, Bengkulu City. The purpose of this study was to determine the service life of the building’s exterior paint. The method used in this research was the factor method, which involves calculating the Estimated Service Life (ESL) based on known environmental factors and Reference Service Life (RSL) values. The results of the study indicated that the estimated service life of the building's exterior paint, using the factor method, is approximately 8.56 years. Based on these findings, it is recommended that periodic inspections and maintenance be conducted approximately every 8 years to ensure the exterior paint remains in good condition.

Abstract

Water treatment sludge (WTS) generated from water treatment plants (WTPs) contains organic matter (OM) that may be released during storage prior to the dewatering process due to the influence of temperature and oxygen. The release of OM from WTS can deteriorate the quality of treated water if the dewatering effluent is recycled back into the WTP system. This study aims to investigate changes in the quality of OM in WTS during storage under varying temperatures (20°C and 40°C) and oxygen conditions (oxic and anoxic). The characteristics of released OM were evaluated by measuring dissolved organic carbon (DOC), ultraviolet absorbance at 260 nm (UV260), and fluorescence Excitation-Emission Matrix (EEM). The Specific UV Absorbance (SUVA) parameter was also calculated to assess the aromatic content of OM. The highest DOC concentration (4.94 mg/L) was observed under anoxic conditions at 40°C, which was 4.3 times higher than the lowest value found under oxic conditions at 20°C (1.14 mg/L). The highest UV260 absorbance (13.55 m⁻¹) and SUVA value (2.74 m⁻¹/(mg/L)) were also found under the anoxic 40°C condition, indicating a dominance of aromatic and humic-like substances formed during storage. EEM fluorescence analysis detected three main peaks representing protein-like, fulvic acid-like, and humic acid-like substances. Fulvic and humic acid-like substances were released more abundantly under anoxic conditions compared to protein-like substances. Differences in oxygen and temperature conditions play a significant role in determining the characteristics of OM released from WTS.
