Abstract

Roads are land transportation infrastructure that includes all parts of the road system, such as connecting structures, complementary buildings, and equipment intended for traffic activities on, above, and below the ground surface, including water surfaces, excluding railways, haul roads, and cable roads. This research aims to identify the condition of environmental roads in Lereng Village, Kuok District, and to produce a spatial distribution map of the environmental road network. The study applies a survey-based quantitative descriptive method, focusing on describing actual conditions and revealing factual problems found in the field. Primary data were obtained through direct field observations and measurements, while secondary data were collected from related institutions. Geographic Information Systems were selected as the main analytical tool due to their ability to manage spatially referenced data, process complex structures, and efficiently support decision making related to road infrastructure management. The results show that most environmental roads in Lereng Village are in damaged condition, dominated by potholes, longitudinal cracks, and surface deterioration. Several roads are classified as heavily damaged, including Transad Alley 1, Transad Road 2, and other local roads within the village area. These conditions reduce driving comfort and safety for road users and indicate the urgent need for improvement. The mapping results produce an environmental road condition map with priority scores ranging from 9 to 18. Roads with priority values greater than 7 are categorized as requiring routine maintenance, providing a basis for planning maintenance and rehabilitation programs.

Abstract

Riau Province is one of Indonesia’s largest palm oil–producing regions, generating substantial biomass waste such as palm kernel shells. One potential use of this waste is Palm Kernel Shell Ash (PKS-Ash), which contains silica (SiO₂) and alumina (Al₂O₃) that are beneficial for cementitious reactions. This study aims to evaluate the effect of PKS-Ash as a cement additive on the properties of Cellular Lightweight Concrete (CLC) bricks, particularly unit weight, water absorption, and compressive strength. A laboratory-scale experimental method was applied. The test specimens were produced using cement, sand, water, a foaming agent, and PKS-Ash with variations of 0%, 4%, 6%, and 8% by weight of cement. All specimens were tested at curing ages of 7, 14, 21, and 28 days in accordance with SNI 8640-2018. The results at 28 days showed that the addition of PKS-Ash significantly influenced the characteristics of the CLC bricks. Compressive strength increased with higher PKS-Ash content, reaching a maximum value of 1.775 MPa at the 8% variation, compared to 0.975 MPa for the control mixture. The unit weight of the specimens ranged from 1,304.29 kg/m³ to 1,716.44 kg/m³. Water absorption values varied, with the lowest absorption observed in the 0% mixture and the highest in the 4% mixture. The study concludes that PKS-Ash has strong potential as a sustainable additive to improve the compressive strength of CLC lightweight bricks while promoting effective utilization of palm oil industry waste.

Abstract

Construction project delay is a condition where the execution of work does not proceed according to the agreed schedule. The construction project of Norfa Husada Mother and Child Hospital experienced delays impacting costs and operational time. This study aims to identify the factors causing delays, determine the most dominant factors, and formulate preventive measures. The method used was a questionnaire distribution to 30 respondents directly involved in the project, including contractors, consultants, and project owners. Data were analyzed using descriptive statistics (Mean Rank) with SPSS software. The results show that the Planning Factor is the most dominant cause, specifically due to design changes (redesign) and changes in the scope of work, with a mean value of 1.97. The second dominant factor is the Execution Factor, particularly regarding poor work sequence planning, with a mean value of 1.90. Based on these results, the main strategies to prevent delays include maturing the design planning before construction begins, strengthening coordination between the owner and contractor regarding scope changes, and establishing a more structured method of execution (SOP) in the field.

Abstract

This study aims to analyze the effect of adding rice husk ash on the compressive strength of Cellular Lightweight Concrete (CLC) blocks. The research background is based on the need for building materials that are lightweight, environmentally friendly, and possess adequate mechanical strength. Rice husk ash is used as an additive material due to its high silica content and its potential to enhance the bonding between particles in the lightweight concrete matrix. The research method employed is an experimental method with variations in the addition of rice husk ash of 0%, 2.5%, 5%, and 10% by weight of cement. The test specimens were cube-shaped and were tested at the ages of 7, 14, and 28 days in accordance with SNI 8640-2018. The results indicate that the compressive strength increases with both the concrete age and the percentage of rice husk ash addition up to an optimum limit. At the age of 28 days, the highest compressive strength was obtained at the 10% rice husk ash variation, reaching 3.63 MPa, while the 5% variation produced a compressive strength of 3.33 MPa. Compared to lightweight blocks without the addition of rice husk ash, all variations exhibited a significant increase in compressive strength. Based on these results, it can be concluded that the addition of rice husk ash up to 10% is effective in improving the compressive strength of CLC lightweight blocks and meets the requirements for non-structural lightweight blocks.
