Abstract

Islamic Boarding School Hidayatul Muslimin 1 is situated in West Kalimantan Province. This school features 19 classrooms constructed from basic wooden structures. The educational facilities available at this school, including tables, chairs, blackboards, and shoe racks, were insufficient to facilitate effective learning; some students even had to sit on the floor due to the lack of teaching and learning facilities. In addition, the classroom walls look dull because the paint has faded, so they display the original color of the wood that is the material of the classroom walls. This Community Service initiative aims to create learning facilities that will not only foster a comfortable learning environment for students but also enhance the practical skills of Civil Engineering students in woodworking applications. The Community Service team and Civil Engineering students who practiced woodworking at the Civil Engineering Department Workshop at Pontianak State Polytechnic executed the project to create these educational facilities. The learning facilities created for Hidayatul Muslimin 1 Islamic Boarding School in West Kalimantan include 20 tables, 40 chairs, two whiteboards, and four shoe racks. Additionally, with the support of Civil Engineering students, several teachers, and students from the Islamic boarding school, the Community Service team renovated and painted two classrooms.

Abstract

Rapid developments in the construction era are shown by using the latest technology to improve efficiency and effectiveness in project implementation. One of the technologies widely used by construction experts today is Building Information Modeling (BIM). Building Information Modeling (BIM) is a digital-based concept that integrates 3D modeling and stores important information in the design, construction, and maintenance processes. Given the high demand for workers who are competent in BIM, there is a necessity for coaching or training on BIM applications to ensure that the developed workforce can fulfill the job market requirements. The purpose of this Community Service was to train students of SMK N 8 Pontianak with a concentration of expertise in Building Information and Modeling Design so that these students can better understand the concept of BIM. This training used AutoCAD and SketchUp software as tools for basic levels from 2D to 3D. The training results indicated that 74.18% of students at SMKN 8 Pontianak comprehended the concept of BIM, which they were previously unaware of, compared to a 28.64% percentage prior to the training. In addition, the ability of SMKN 8 Pontianak students to apply AutoCAD and SketchUp software has increased, as evidenced by the results of the images before and after the training. These results are anticipated to empower SMKN 8 Pontianak students to utilize their skills proficiently in the job market.

Abstract

This research explores both the structural behavior and environmental relevance of sidewalk and deck slab components in composite steel-concrete bridge systems, emphasizing principles of sustainability and resilience to climate change. The focus was placed on the structural planning of the Palempay 5 Bridge, a Class A bridge located in West Kalimantan, Indonesia, which features reinforced concrete for both pedestrian pathways and vehicle lanes. The design follows key Indonesian standards, including SNI 1725:2016 for bridge loading, SNI T-12-2004 for concrete bridge structures, and SNI 2847:2013 for general concrete design. Using SAP2000, the bridge components were analyzed under multiple loading scenarios such as dead loads, live loads, pedestrian impact, and environmental factors like wind and thermal variation. The reinforcement was designed to maximize efficiency while ensuring structural integrity and durability. The analysis demonstrated that a sidewalk thickness of 50 cm and a deck slab thickness of 20 cm, reinforced with D16 and D13 bars, provided sufficient strength and serviceability. Furthermore, the bridge elements were shown to perform effectively under environmental stresses, aligning with climate-resilient design principles. This study contributes to the development of environmentally conscious infrastructure by combining optimized structural design with ecological considerations. It offers practical insight for civil engineers seeking to implement designs that reduce material consumption, lower carbon emissions, and enhance durability in the face of environmental change.
