ABSTRAK In the implementation of excavation work on the Revitalization of Lake Bakuok project in Kampar Regency, heavy equipment assistance is needed to facilitate the work process, one of which is in excavation and soil transportation. The gradual or relay excavation method causes problems such as high equipment efficiency and fuel consumption so that operational costs increase and the du…
ABSTRACT Concrete is one of the main construction materials widely used in infrastructure development due to its high compressive strength and good durability. However, achieving optimal compressive strength typically requires a relatively long curing period, approximately 28 days. To address this limitation, admixtures such as Bestmittel are used to accelerate the hardening process and improv…
ABSTRACT Flooding is a major problem that has the potential to occur during the rainy season. The re-planning of drainage channel dimensions in the Jalan Suka Karya km 0-km 2.7 Area can be used as an effort to control flooding problems. The purpose of this research is to evaluate the existing conditions of drainage channels that cause flooding in the research location and determine alternative…
ABSTRACT The CWR-01 AKSI ADB UNRI Integrated Classroom Building contruction project had only reached 70.051% progress by the end of October 2023, while it was supposed to be 100%, resulting in a 29.498% delay. Because of this, it’s important to identify the risk that caused the delay. This study aims to identify potential delay risk using the Item-Level Content Validity Index (i-CVI), and an…
ABSTRACT The increasing development of construction projects has led to a rising demand for concrete. Concrete is a mixture of Portland cement or other hydraulic cements, fine aggregates, coarse aggregates, and water, with or without admixtures. The purpose of adding admixtures is to modify one or more properties of the concrete. Concrete with Type E admixtures (water-reducing and accelerating…
ABSTRACT In the design of multi-story building structures, load distribution is one of the key factors that significantly affects the stability and seismic performance of the building. One common load found on the roofs of high-rise buildings is a water tank. An asymmetrical floor plan, such as an L-shaped layout, can result in the center of mass and the center of rigidity not coinciding, whic…
ABSTRACT The distribution of clean water remains a challenge, especially in rural areas. To address this issue, the government has implemented the PAMSIMAS Program as an alternative solution for providing clean water. However, due to the conventional distribution system being less than optimal, further analysis is conducted through numerical simulations using the EPANET 2.2 software to identif…
ABSTRACT Merpati Sakti Street in Pekanbaru City has experienced significant damage due to increased traffic volume and vehicle loads. Based on previous studies, the road’s condition is categorized as 'very poor' with a Pavement Condition Index (PCI) of 21.5. This study aims to design the thickness of a rigid pavement using the 2024 Road Pavement Design Manual method to enhance the road’s du…
ABSTRACT The quality of road construction is greatly influenced by proper design, particularly in the selection of pavement types and the planning of pavement layer thickness. One important aspect of this design is considering the service life or design life, which is how long the pavement can withstand traffic loads. In pavement design, it is very important to follow established guideline…
ABSTRACT Flexible pavement planning on peat soil requires a special approach because of its highly compressible nature and low bearing capacity. According to data from the Ministry of Environment and Forestry, Riau Province is one of the five provinces with the largest peatland distribution in Indonesia, at around 5.3 million hectares. This fact highlights the critical importance of design…
ABSTRACT The Simandolak II Irrigation Network is part of the Simandolak-Pangean Irrigation Area located in Jalur Patah Village, Sentajo Raya Subdistrict, Kuantan Singingi Regency. This network utilizes the flow of the Batang Air Hitam River as its primary source of irrigation water and covers an area of 690.10 hectares. The purpose of this study is to analyze the performance of the physica…
ABSTRACT Fire is one of the disasters that can cause great losses, both in terms of property and safety of life. The Indragiri Hilir DPRD Office Building, as a public facility with high activity, requires a reliable fire protection system to anticipate this risk. This study aims to analyze the level of reliability of the fire protection system in the building based on four main components, nam…
ABSTRACT The construction sector is one of the industries with the highest risk of occupational accidents. The complexity of tasks, the use of heavy equipment, and dynamic work environments make the implementation of Occupational Health and Safety (OHS) systems essential. This study aims to analyze risk control within the implementation of OHS systems and evaluate its compliance with …
ABSTRACT Sandy clay soil is a type commonly found in coastal areas and often exhibits low shear strength, thus necessitating a study on its mechanical behavior. This research aims to analyze the effect of varying bentonite and kaolin ratios on the shear strength parameters of the soil, namely cohesion (c) and internal friction angle (φ), in sandy clay soil mixtures. Soil samples were prep…
ABSTRACT The Mandau River is a tributary of the Siak River and plays a vital role in providing clean water, supporting irrigation, and sustaining the ecosystem in the Bengkalis and Siak regencies. This study aims to analyze the dependable flow (Q90) of the Mandau River at the Mandau River Bridge point as a basis for sustainable water resources planning. The method used is the Mock method, …
ABSTRACT Merpati Sakti Street in Pekanbaru City has suffered damage due to high traffic volume and poor drainage conditions.
