Abstract

Proyek konstruksi merupakan kegiatan kompleks yang keberhasilannya sangat ditentukan oleh ketepatan waktu dan efisiensi biaya. Namun dalam pelaksanaannya, sering terjadi keterlambatan dan pembengkakan anggaran yang berdampak pada menurunnya kinerja proyek. Untuk itu, dibutuhkan metode pengendalian yang mampu memberikan gambaran menyeluruh dan terukur terhadap aspek waktu dan biaya. Penelitian ini menganalisis kinerja waktu dan biaya pada proyek pembangunan Gedung Kuliah Terpadu di Lhokseumawe, Aceh, dengan pendekatan Earned Value Management (EVM). Metode ini mengintegrasikan jadwal, anggaran, dan hasil fisik aktual untuk menghasilkan indikator kinerja yang objektif dan prediktif. Hasil analisis menunjukkan bahwa proyek secara umum efisien dalam aspek waktu dan biaya. Namun, pada minggu ke-12 hingga ke-18 ditemukan deviasi negatif yang menunjukkan keterlambatan dan pemborosan anggaran. Meskipun demikian, proyek tetap selesai sesuai jadwal dengan estimasi total biaya Rp. 27,84 miliar dan keuntungan sekitar Rp. 2,01 miliar atau 6,74% dari nilai proyek. Temuan ini membuktikan bahwa EVM efektif sebagai alat bantu manajemen proyek dalam memantau dan mengendalikan kinerja secara berkala, serta mampu mendeteksi potensi penyimpangan sejak dini. Dengan demikian, metode ini layak diterapkan pada proyek-proyek konstruksi skala menengah hingga besar.

Abstract

Reactive powdered concrete is a new type of concrete which has ultra high compressive strength. The constituent components are very fine powders which have a high silica content. This aims to improve the reaction that occurs in concrete and increase the homogeneity of the concrete. Reactive powder concrete consists of cement, silica fume, quartz with a maximum diameter of 300 μm, superplasticizer and steel fiber to increase ductility. Reactive powder concrete which has high compressive strength and high ductility has the potential to replace steel materials in construction work. Has a very big opportunity for construction materials in Indonesia considering the availability of the materials needed, especially quartz. This research is the first step towards the possibility of developing reactive powdered concrete in Indonesia, which is based on previous research. Experiments were carried out to obtain a reactive powdered concrete mixture with local materials. This experimental behavior serves to connect the compressive strength and bending with the formula 0.62fc '. The results showed that the compressive strength was 32.85 MPa and the flexural strength 3.25 MPa and the compressive strength produced by the reactive powder concrete was of medium quality concrete, this was due to differences in the composition and characteristics of the superplasticizer, silica fume, cement, or sika fiber used

Abstract

In the construction sector, the Construction Safety Management System (SMKK) has been determined by the Regulation of the Minister of Public Works No. 10 of 2021 as a reference for addressing the risk of industrial accidents and improving building safety. Full implementation of occupational safety (K3) can minimize the risk of work accidents. However, in reality, there are still many obstacles for companies and employees, and many accidents in the workplace are caused by unsafe behavior factors by the workers themselves. The methodology used in this study involves various approaches, such as literature review and primary data acquisition through questionnaires targeting respondents in construction project environments. The collected data will be analyzed using the Structural Equation Modeling method to identify important variables. Data processing was performed using the Smart-PLS version 4.1.0.1 application to determine the outer and inner models. Hypothesis testing was conducted using bootstrapping, considering the Original Sample values, T-statistics, and P-values. Based on the results, it is concluded that safety leadership has a significant indirect influence on improving safety performance. The strengthening of leadership aspects has the largest impact on improving safety culture, which then influences the improvement of construction safety performance, with an original sample (O) value of 0.273, a sample mean (M) of 0.277, a standard deviation (STDEV) of 0.177, a T-statistic value of 2.324, and a P-value of 0.001. Furthermore, effective safety evaluation (e.g., constructive and systematic evaluation) can help build a stronger safety culture, which in turn will improve overall safety performance. The implementation of innovation in construction processes or safety technology can also encourage better safety behavior among workers, which then contributes to improved safety performance.

Abstract

The implementation of the Occupational Safety and Health Management System (SMK3) in construction projects is an absolute necessity considering the high potential risk of work accidents. This study aims to evaluate the extent to which SMK3 is implemented in the construction project of the POLRI and BIN Flats (Rusun) in the Core Area of ​​the Government Center (KIPP) of the National Capital City (IKN). The research method used is a quantitative approach by distributing questionnaires to 106 respondents consisting of project managers, supervisors, and field workers. The results of the analysis show that the average level of SMK3 implementation is in the good category (mean = 4.06 on a scale of 5). The highest indicators are in the safety culture aspect and the role of the K3 manager. However, there are still challenges in the logistics and coordination aspects across jobs. This study recommends increasing the integration of safety technology and regular training for workers.

Abstract

There are two access bridges that have different functions and to cross the Ciliwung river below as an access road from the RSCM Kencana building to RSCM Kirana. Where there is access to the bridge that is specifically for car/motorcycle riders and a special bridge for pedestrians. However, the density of motorists and pedestrians can hinder traffic access. Thus, supporting infrastructure was built, namely a vehicle bridge and connecting pedestrians from the Kencana RSCM building to the Kirana RSCM building. The type of bridge built is a concrete slab steel frame bridge. In this regard, this study aims to determine the values of the ultimate moment, shear, and axial forces that occur with the object viewed from the longitudinal and transverse girders whether they exceed the nominal profile value or not, and the deflections that occur on the behavior of the structure. on the bridge according to SNI 1725:2016 loading with the help of the MIDAS Civil 2019 software. From the results of the calculation and capital analysis on the MIDAS Civil 2019 software, the values of the internal forces on the object under review do not exceed the nominal strength value of the profile. First, the girder extends against ultimate moment of ϕMn ≥ Mu = 3.762,080 kNm ≥ 528,869 kNm, against shear force ϕVn ≥ Vu = 1.095,444 kN ≥ 909,282 kN, against axial compressive force ϕPn ≥ Pu = 8.532,876 k N ≥ 3.115,265 kN, to the axial tensile force ϕPn ≥ Pu 7.726,842 kN ≥ 2.434,744 kN. Second, the transverse girder with respect to the ultimate moment of ϕMn ≥ Mu = 1.242,046 kNm ≥ 53,723 kNm, against the shear force ϕVn ≥ Vu = 1.076,400 kN ≥ 81,513 kN, against the axial compressive force ϕPn ≥ Pu = 3.805,349 kN ≥ 255,812 kN. The deflection value that occurs at the ultimate state of the structural behavior of the bridge is 48.70 mm where this value is still smaller than the allowable deflection of 55 mm. So it can be concluded that the bridge structure is safe when it receives the ultimate load.

Abstract

The intersection of Jalan H. Rais is where 3 (three) roads meet, namely Jalan H. Jamat Gang Rais, Jalan Puspitek Segment 1, and Jalan Puspitek Segment 2. This intersection often experiences long queues due to inadequate intersection capacity so that it cannot accommodate the volume of vehicles during morning and evening rush hours. The research method used was a direct survey method at the research location to collect traffic data at the H. Rais intersection and the surrounding roads. The research results found that the average length of the queue before handling during peak hours on weekdays was 168.52 m and delays were 35,471 with an intersection service level (LOS) D, while the average length of the queue before handling during peak hours on holidays was 119 .82 m and a delay of 33.52 with a level of service (LOS) D. H. Rais intersection performance for the next 5 years, before handling becomes worse with the result that the average queue length during weekday peak hours is 219, 64 m and a delay of 49,137 with an intersection service level (LOS) E, while the average queue length during holiday peak hours is 218.28 m and a delay of 43,635 with an intersection service level (LOS) E. Handling that needs to be done at the intersection H. Rais road in short-term scenario 1 is by providing road equipment facilities and assignment of traffic officers, and in short-term scenario 2 by widening the bend radius to a minimum of 7.8 m and widening the H. Jamat Gang Rais road to 6 m, while The treatment carried out at the H. Rais intersection in the long term is to change the Puspitek road type to 4/2-T with a width of 6 m per direction.

Abstract

Groundwater recharge is a crucial factor in determining the permissible groundwater extraction within a watershed. In the Cikapundung watershed, the contribution of groundwater to raw water supply has been continuously declining, prompting a shift from groundwater to surface water usage. This study aims to quantify the groundwater recharge volume and recharge coefficient for each geological formation within the Cikapundung-Gandok watershed, covering an area of 90.4 km², and to compare the results with previous studies. The analysis estimates recharge volumes based on rainfall data from 8 stations around the Cikapundung-Gandok watershed from 2010 to 2019, geological formation data, and alternative recharge coefficients. The difference in recharge volume from previous studies is 393,348 m³/year or 1%. Two formations, Qvu and Qyu, which were not identified in earlier studies, supplement the existing geological dataset. The selected recharge volume for the Cikapundung-Gandok watershed is 33,232,004 m³/year or 1.05 m³/s, with the lowest contribution from the Lava formation (Qyl) at 1,364,504 m³/year or 0.04 m³/s and the highest from the Old Volcanic Product (Qvu) at 14,072,243 m³/year or 0.45 m³/s. The tentative recharge coefficients for each rock formation are as follows: Colluvium (Qc) 30%; Unweathered Old Volcanic Product (Qvu) 20%; Sand Tuff (Qyd) 10%; Lava (Qyl) 25%; Pumiceous Tuff (Qyt) 20%; and Young Volcanic Product (Qyu) 20%. The groundwater recharge data obtained can be used to set groundwater extraction limits and to plan for groundwater management using a conservative approach to ensure long-term sustainability.Keywords: groundwater recharge, recharge coefficient, geological formation, groundwater exploitation, Cikapundung-Gandok Watershed

Abstract

The aviation industry increasingly relies on composite materials to optimize performance and reduce weight in high-speed aircraft structures. These materials offer superior strength-to-weight ratios, corrosion resistance, and design flexibility. Understanding the mechanical properties of composite materials is essential for enhancing the safety and efficiency of high-speed aircraft. This research aims to analyze the strength characteristics of composite materials used in high-speed aircraft structures. The study focuses on evaluating the mechanical properties and performance under various loading conditions to determine their suitability for aviation applications. An experimental approach was employed, involving the fabrication of composite samples using different matrix and fiber combinations. Tensile, compressive, and flexural tests were conducted to assess mechanical properties. Data were collected and analyzed to evaluate the performance of each composite configuration under simulated operational conditions. The findings indicated that hybrid composite materials exhibited the highest strength and stiffness, outperforming traditional materials. The tensile strength of the best-performing composite reached up to 600 MPa, while flexural tests showed significant resistance to deformation. These results highlight the potential of advanced composites to enhance the structural integrity of high-speed aircraft. The research underscores the importance of selecting appropriate composite materials for high-speed aircraft applications.
