Abstract

This study explores the application of bamboo piles as a sustainable ground improvement technique in the construction of an athletic track at the Malabar National Athletic Training Center in Pangalengan, West Java. Utilizing a qualitative case study approach, the research documents the implementation methods, technical considerations, and performance outcomes of bamboo pile foundations in addressing geotechnical challenges posed by soft clay soils and high groundwater levels. The bamboo piles, made from Gigantochloa apus, were systematically prepared, treated with borax-boric acid for durability, and installed in a triangular grid pattern to enhance soil bearing capacity and minimize settlement. The integrated foundation system, combining bamboo piles with gravel layers, drainage systems, and a synthetic track surface, met the International Association of Athletics Federations (IAAF) performance criteria, achieving a bearing capacity improvement of 180-220% and maximum settlement of 12 mm. The approach offered significant economic benefits, with 35-45% cost reductions compared to conventional concrete piles, and environmental advantages, including a 60-70% lower carbon footprint. This research underscores the viability of bamboo piles as a cost-effective, environmentally friendly solution for specialized construction, bridging traditional knowledge with modern engineering practices. Recommendations for future applications include rigorous geotechnical investigations, quality control, and long-term performance monitoring to ensure reliability.

Abstract

Laminated concrete involves removing a thin layer from the concrete surface, making it prone to abrasion and weakening the structure. This delamination, often termed concrete weathering, produces a "drumming" sound when the surface is hammered, signaling the need for repair to prevent further spread. Delamination can result from poor concrete mix or casting issues, such as segregation when fresh concrete is poured. Quality control is crucial before pouring concrete into formwork for columns and walls. Checks like the slump test ensure proper workability, while concrete test specimens verify the mix meets the 28-day characteristic compressive strength. Casting concrete from heights exceeding 1.5 meters can cause delamination by segregating fine and coarse aggregates. Repairs for delaminated surfaces include grouting, plastering, or injecting. In a 4-story house construction project, plastering is often preferred due to the ready availability of materials like fine sand and cement, making it an effective solution. To summarize, delamination weakens concrete structures and requires timely detection and repair. Proper quality control during concrete mixing and casting, including slump tests and strength verification, helps prevent segregation and delamination. For repairs, plastering is a practical choice in multi-story projects due to material accessibility

Abstract

Artificial Intelligence (AI) is recognized for its speed and accessibility. It is rapidly spreading as people incorporate its functions into daily activities, such as searching for information, purchasing necessities, and designing models. Alongside the development of AI, Indonesian translations for AI terms have emerged. This study explores the variations in Indonesian translations of English AI terms. The results show that out of ten (10) English AI terms, three (3) translated terms are found on both the Pasti and Google websites. Meanwhile, the remaining seven (7) translated terms are not available on Pasti but are found on the Google website. Even when translating the same AI term, the Pasti and Google websites show variation. These variations include a partial-word (1 term), a full-word (1 term), and a letter (1 term), highlighting the diversity in Indonesian translations of English AI terms. This study is expected to contribute to the enrichment of the Indonesian AI terminology glossary.

Abstract

This study investigates the implementation methods of the PERI formwork system for reinforced concrete column structures in the KAI CO-Living Gondangdia project, an 8-story residential building in Central Jakarta. Employing a qualitative case study approach, the research documents the assembly, installation, concrete placement, and removal processes of the PERI system during a three-month internship. Key aspects analyzed include material preparation, panel assembly, alignment techniques, quality control measures, and safety protocols. The PERI system, characterized by modular steel-framed panels and phenolic-coated plywood, facilitated rapid assembly (45-60 minutes per column), high dimensional accuracy (±3mm tolerance), and excellent concrete surface quality for 85% of columns. The system’s reusability (24 cycles) and reduced labor requirements (25% less than traditional methods) enhanced project efficiency. Standardized procedures, skilled labor, and rigorous quality control were critical to success, though specialized training was necessary. The findings highlight the PERI system’s advantages in speed, quality, and cost-effectiveness for repetitive structural elements, offering practical insights for optimizing formwork in modern construction. Recommendations include investing in crew training, detailed planning, and comprehensive quality protocols to maximize system benefits.

Abstract

Mass transit systems such as Light Rail Transit (LRT) offer an efficient and environmentally friendly solution to urban mobility challenges. The performance of LRT systems is highly influenced by track geometric design, particularly in segments involving curve radii and long-span structures. The analysis is based on technical parameters such as centrifugal force, track elevation (superelevation), and railway geometric standards as stipulated by national regulations. The findings indicate a reduction in operational speed on certain curved sections where the radius does not align with ideal design speeds, primarily due to geometric constraints and safety considerations.
