Abstract

This study aims to examine the structural analysis of wall elements in the LINAC room of the Radiotherapy Building construction project at ODSK Hospital, Manado, and to determine the estimated cost required for the wall element work based on the structural analysis results. The research was conducted on the Radiotherapy Building construction project at ODSK Hospital from August 2024 to December 2024. The research methods included structural analysis of the walls, estimation of the Bill of Quantity (RAB), and analysis using ETABS software. The data used were secondary data obtained from the project and processed using Microsoft Excel and ETABS. The analysis results show that the LINAC bunker walls modeled as reinforced concrete structures meet the strength and stiffness requirements based on the analysis of axial forces, shear forces, bending moments, and structural displacement. The main material requirements consisted of 668.768 m³ of concrete, 4,423.47 kg of D16 reinforcement, 323.12 kg of P10 reinforcement, and 402.96 m² of formwork. The cost analysis resulted in a total construction cost of IDR 1,281,464,449 before VAT and IDR 1,422,425,538 after 11% VAT. Compared with the project RAB of IDR 2,358,932,981, there was a difference of IDR 1,077,468,532, or approximately 45.68%, with the estimated RAB from the analysis being lower. The cost difference was influenced by concrete strength specifications, unit prices, work volume, and the calculation basis used.

Abstract

Construction activities significantly contribute to natural resource consumption and waste generation, making the implementation of green construction principles increasingly important, particularly in continued projects that were previously halted. This study aims to identify the aspects of construction implementation that have and have not met green construction indicators, and to analyze the level of implementation in the aspects of structure, material, and construction waste management at the Metland Marron Hotel Construction Project in Tomohon, which was halted in 2020 and resumed in 2025. The study employed a quantitative descriptive method with an evaluative approach based on an assessment model consisting of 15 indicators on a 0–2 scoring scale, with data collected through field observation, project documentation, and questionnaires administered to five respondents in managerial and supervisory positions. The results show that the overall level of green construction implementation reached 79.3 percent, categorized as good. The structural aspect achieved the highest score (90.0%) through the reuse of existing structures without demolition, followed by construction waste management (82.0%), while the material aspect obtained the lowest score (66.0%) due to limited use of environmentally friendly fabricated materials and local suppliers. This study concludes that continued construction projects have greater opportunities to implement green construction principles compared to new projects because they can utilize existing structures, although sustainable material management still requires further attention from project implementers.

Abstract

Worldwide, hospitals and other health-care facilities are among the largest institutional consumers of energy and generators of carbon emissions, which explains the growing push for these buildings to operate more sustainably. This paper examines how well the emerging Advent Hospital Manado design measures up against the green-building benchmarks contained in GREENSHIP New Building Version 1.2. As the building is still early in construction, only the Design Recognition (DR) stage was assessed, capping the achievable score at 77 points. Evidence was drawn from a review of planning documents—the Detailed Engineering Design (DED), the Bill of Quantities (BOQ), and the not-yet-finalized technical specifications (RKS)—together with on-site inspection used to corroborate the paperwork. Scoring placed the design at 27 out of 77 points (35.06 percent), a result that clears the threshold for an indicative Bronze rating. Sensitivity testing indicates the score has room to climb toward a Gold rating of 48 points, provided the mechanical team runs thermal simulations, the basement sump is converted into a dual-plumbing setup for recycled water, and formal environmental-management procedures are put in place. Taken together, these results show that the preliminary design already satisfies core sustainability principles, though confirming its real-world operational performance will have to wait until the building is finished and in use.

Abstract

Churches in North Sulawesi are often built in stages, so one building may contain concrete from several periods and seismic code generations. Indonesian church assessments mostly describe damage in a single building and offer no repeatable procedure linking age, measured damage, and testing depth. This article proposes such a procedure for reinforced concrete churches. It has four stages: screening with age categories tied to thresholds of 10 and 50 years, a 0 to 4 visual damage score for accessible columns, beams, and slabs, non-destructive testing whose density follows an age–damage matrix, and an ordered rule assigning one of four fitness statuses. Screening placed three GMIM churches completed in 2022, 1989, and 1967 in the new, old, and aged categories. A deterministic test of the initial draft showed that one column scored 3 yields a condition value of 63.7 with published AHP weights and 75.0 with equal weights, so a new church with a severely cracked column would receive only basic or extended testing. A graded critical-element rule was added, and enumerating all 64 score combinations confirmed that it sends every such column to the highest testing level. Weights, testing thresholds, and statuses still require expert validation and field calibration.

Abstract

Pertumbuhan ekonomi dan populasi manusia telah menyebabkan perkembangan infrastruktur jalan yang pesat, yang secara langsung meningkatkan emisi gas rumah kaca. Studi ini bertujuan untuk mengevaluasi total jejak karbon perkerasan lentur dan kaku menggunakan metode penilaian siklus hidup (LCA) dengan kendala sistem dari hulu ke hilir (cradle-to-site). Studi kasus dilakukan pada Proyek Perbaikan Jalan Wawali di Desa Wioi, dari segmen STA 0+400 hingga STA 0+500. Penelitian kuantitatif ini menggunakan pendekatan studi kasus dengan data sekunder berupa RAB dan gambar kerja untuk menghitung volume material dan durasi operasional alat berat. Emisi dihitung berdasarkan faktor emisi dari basis data Inventory of Carbon & Energy (ICE) dan pedoman IPCC/DESNZ. Hasil menunjukkan bahwa total emisi jejak karbon mencapai 11.522,12 kgCO2e. Perkerasan lentur memberikan kontribusi emisi yang lebih besar (7.639,01 kgCO2e) dibandingkan perkerasan kaku (3.883,11 kgCO2e). Berdasarkan tahapan siklus hidup, pengadaan material pada fase produksi merupakan penyumbang emisi terbesar (52%), diikuti oleh fase transportasi (45%) dan konstruksi di lokasi (3%). Temuan ini menunjukkan bahwa perkerasan kaku secara kumulatif lebih ramah lingkungan. Strategi pengurangan karbon yang direkomendasikan meliputi optimalisasi penggunaan material ramah lingkungan seperti Warm Mix Asphalt (WMA) dan peningkatan efisiensi rantai pasokan logistik dari tambang ke lokasi proyek.
