Abstract

 Abstract — The Sunan Ampel Islamic Boarding School building is a religious education facility that has been operating for 15 years. Routine maintenance has not been carried out on the building, resulting in a decline in quality. Over time, many factors can cause a decline in quality and damage the structure and architecture of the building. Therefore, to maintain the function and usability of the building, researchers need to assess the condition of the building. This study aims to determine the overall condition value of the building. In the process, data collection was carried out using the observation method while data processing used the Condition Survey Protocol 1 (CSP 1) Matrix method by adjusting the predetermined criteria. The results of this study can determine the condition value of the building at the Sunan Ampel Islamic Boarding School building. After data analysis, there were 359 damages in the Sunan Ampel Islamic Boarding School building. Of which 343 damages require planned maintenance, 10 damages require condition monitoring, and 1 damage requires serious attention. Based on the Condition Survey Protocol 1 (CSP 1) Matrix method, the overall building condition scored 1.25 (on a scale of 1-4), indicating the building is classified as good, meaning the structure remains strong and stable. Damage/defects are limited to the exterior.Keywords: Building Structure; CSP; Matriks; Condition Assesment

Abstract

In project implementation, both owners and contractors place great emphasis on timely completion. However, project delays often occur, necessitating an effective time performance analysis method to minimize the risk of delays. Therefore, a project time performance analysis was conducted by comparing actual field data with the initial plan. This study used a quantitative descriptive approach by analyzing variables from field observation data. The project was scheduled for completion on December 30, 2025, with a duration of 514 calendar days. The analysis was conducted in the 35th and 48th weeks of project implementation. The results in the 35th week showed a slower project completion prediction, namely around February 22, 2026. However, in the 48th week, the project was estimated to be completed earlier, namely on December 27, 2025, where the contractor could save 0.37% of the overall progress of the plan that had been implemented.

Abstract

This study compares the effectiveness of three soil improvement methods—Stone Column, Modular Grout Column (MGC), and Deep Soil Mixing (DSM)—in reducing settlement for a 5000 m³ fuel tank. Using a 2D numerical modeling approach, the settlement reduction for each method was analyzed. The results showed that MGC was the most effective, achieving a 52% reduction in settlement, followed by Stone Column (47%) and DSM (39%). These findings emphasize the importance of selecting the appropriate soil improvement method based on soil conditions. For optimal results, increasing column diameter is recommended.

This study aims to analyze occupational accident risks in an educational building project in Sumedang Regency by identifying key risk factors and corresponding control measures. Data were obtained from questionnaires distributed to 10 respondents with at least two years of field experience. The analysis employed likelihood and severity matrices (AS/NZS 4360:2004) and the Bowtie method to map the relationship between causes, events, and consequences. Results indicate 45 risk factors, with four classified as high: workers falling during scaffolding installation, concreting, and formwork dismantling, and workers cut by sharp tools during rebar work. Unsafe working conditions and worker negligence were identified as dominant causes. This approach provides a comprehensive understanding of risk management for upper-structure work that can be adapted for similar construction projects.Keywords: work accident risk, risk analysis, Bowtie method, construction project.

Abstract

Abstract — This study evaluates vacuum-assisted soft-clay improvement with Prefabricated Vertical Drains (PVD) and its implications for an in-service buried pipeline along a planned toll-road corridor. A descriptive–quantitative approach with PLAXIS 3D couples ground consolidation and soil–pipeline interaction: PVDs are modeled as line drains on a 1.5 m grid to 22 m depth beneath a permeable sand blanket; a 50 kPa vacuum is applied, and embankment loading is staged in four 1 m lifts (design surcharge 123.6 kPa, vacuum-reduced equivalent ≈ 73.6 kPa, fill height ≈ 4 m). Results show rapid dissipation of excess pore pressure and attainment of ~90% consolidation, with total settlement ≈ 3.10 m by the end of the final dwell (~30 days) and a low residual settlement rate. The pipeline’s peak actions are a bending moment 12.86 kN·m/m, shear 115.4 kN/m, and axial force 2,884 kN/m, producing a governing stress of 381 MPa, safely below the 435 MPa allowable (minimum FS ≈ 1.1). Differential settlement arises from non-uniform loading, with a maximum observed contrast of ~100 mm between loaded and lightly loaded segments.

Abstract

This study analyzes surface runoff and evaluates the effectiveness of Low Impact Development (LID) in the Bumi Harapan residential area, Cileunyi District, Bandung Regency. A descriptive quantitative method was applied using hydrological modeling with PCSWMM. Rainfall data from Cibiru and Cileunyi stations were analyzed, and the log normal distribution with a 2-year return period (83.22 mm) was selected. Rainfall intensity was modeled using the SCS Type I method with a 15-minute interval. The drainage model consisted of 26 subcatchments, 108 junctions, 133 conduits, 1 pump, and 2 outfalls. Initial results showed an average runoff of 79.92 mm, ranging from 65.89 mm (S24) to 81.63 mm (S18). After applying LID controls (rain barrels, rain gardens, bioretention, and permeable pavements), runoff volume decreased significantly—up to 64%, with reductions from 61.61 mm (S26) to 4.29 mm (S24). These results highlight LID’s potential for sustainable stormwater management.

Abstract

The construction of the Gemolong Police Sector Headquarters (Mako Polsek Gemolong) and public facilities in Sragen is a state-owned project built from June 4, 2024, to October 31, 2024. This facility serves as a center for public services and complaints to the Indonesian National Police. The construction includes four detention rooms, each with a maximum capacity of five detainees. These detention rooms are not intended for permanent detention but as temporary holding cells before transfer to permanent prisons. This study assesses the effectiveness of implementing quality, cost, and time management during the construction process. The analytical method used involves comparing the implementation of quality management with the Technical Specifications, comparing the Project Implementation Budget Plan (RAP) with the contractual Budget Plan (RAB), and comparing the initial work schedule (Time Schedule) with the actual field implementation. The findings show that quality management during the construction of the Gemolong Police Headquarters and public facilities met the required technical specifications. However, cost management was deemed unsuccessful because the implementation cost reached IDR 3,625,017,095.07, exceeding the contractual value of IDR 3,414,445,000.00, resulting in the failure to achieve the expected 10% profit margin. Time management was also considered unsuccessful due to a 30-working-day delay in project completion. Based on these results, it is recommended that the Commitment-Making Officer (PPK) review the application of contractual provisions in construction projects and that relevant stakeholders pay greater attention to the implementation of quality, cost, and time management principles in future projects.

Abstract

Bendung irigasi memiliki peran penting dalam menjamin kontinuitas suplai air bagi kegiatan pertanian. Namun, pada banyak kasus, bangunan ini rentan mengalami degradasi akibat gaya hidraulik, erosi, dan faktor usia layanan. Bendung Air Alas di Kabupaten Seluma, Provinsi Bengkulu, mengalami permasalahan struktural, khususnya pada tanggul hulu yang masih menggunakan perlindungan sementara berupa bronjong. Kondisi tersebut meningkatkan risiko erosi serta mengurangi umur layan bendung. Sebagai solusi, direncanakan pembangunan tanggul pelindung permanen menggunakan beton bertulang. Penelitian ini bertujuan untuk mengevaluasi desain dan kinerja struktural tanggul beton bertulang yang diusulkan. Analisis dilakukan dengan mengacu pada Standar Nasional Indonesia (SNI 2847:2019, SNI 1727:2020, dan SNI 1726:2019) serta pemodelan numerik menggunakan perangkat lunak Geo5. Hasil perencanaan menghasilkan tebal dinding 25 cm, tebal telapak 80 cm, dan tinggi total sekitar 8,00 m. Rincian tulangan menggunakan baja D19 dan D13 pada dinding serta telapak. Evaluasi stabilitas menunjukkan bahwa pada kondisi muka air normal maupun banjir, tanggul memenuhi persyaratan keamanan terhadap guling, geser, daya dukung tanah, dan stabilitas lereng dengan faktor keamanan selalu di atas 1,50. Analisis struktur beton juga mengonfirmasi bahwa luas tulangan yang digunakan lebih besar daripada kebutuhan minimum, serta kapasitas geser (VRd) dan momen (MRd) lebih tinggi dibandingkan beban yang bekerja (VEd dan MEd). Temuan ini menegaskan bahwa desain tanggul beton bertulang yang diusulkan aman secara struktural dan layak diimplementasikan. Penerapannya diharapkan dapat meningkatkan keandalan Bendung Air Alas dalam mendukung distribusi air irigasi di Kabupaten Seluma.

Abstract

Abstract — This experimental study evaluates the use of blotong as a substitute material in the manufacture of paving blocks without using gravel. This study prepared 6 samples, with 2 samples tested for compressive strength at 21 days and the other 4 samples tested for compressive strength at 28 days. The results of this study indicate an increase in the compressive strength of the paving blocks as the age of the test specimens increases, from 50–60 kN at 21 days to 45.89–147.86 kN at 28 days. In this study, one of the samples had the lowest compressive strength, namely sample 6 with 45.89 kN. Sample 6 was tested at 28 days, but still showed the worst compressive strength, which could be attributed to the consistency of the mixture, the consistency of compaction, or the material. All test specimens in this study failed to achieve the standards of SNI 03-0691-1996 for Class D paving blocks, as the water absorption and compressive strength values of the test specimens did not meet the minimum values specified in SNI 03-0691-1996.  Keywords: blotong, paving block, compressive strength, water absorption, SNI- 03-0691-1996.
