Abstract

Concrete is a material with the ability to withstand a fairly high pressure, yet it has a low ability to withstand tension. To be utilized as a structure material, improvements need to be made to increase its tensile strength. Addition of fiber in the concrete mixture is recognized to be one among the existing methods to increase the tensile strength. Considering its high tensile strength, This study aimed to examine the compressive strength, the split tensile strength, the flexural and elastic modulus of the normal concrete with Menjalin fibers. The examination was conducted using a cylinder with the diameter of 15 cm and the height of 30 cm and a beam with the size of 15x15x60 cm. Fiber addition was 0.65% of the total concrete materials with various fiber lengths ranging from 2.5 cm, 5 cm, 7.5 cm to 10 cm. The experiment was made by the means of a concrete cylinder compressive test and a flexural test of unreinforced concrete blocks. Results of the study showed, at the age of 21 days, the highest average compressive strength value of 194.37 kg/cm2 and the split tensile strength of 30.43 kg/cm2 in the concrete with fiber of 5 cm long were obtained. The highest flexural modulus value of concrete occurred in the specimen with the fiber length of 7.5 cm (55.7 kg/cm2), while the highest elasticity of concrete occurred in the specimen with the fiber length of 5 cm (2.45x105 kg/cm2).

Abstract

Concrete is a widely used construction material due to its numerous advantages in terms of structural performance, cost-effectiveness, implementation, and maintenance. Compressive strength is a critical property that must be considered for concrete used as a structural component. This property can be influenced by various factors, including the addition of chemical substances to the concrete mix. Alum is commonly employed as a water clarifying agent. In concrete mixtures, alum decomposes into aluminium and trioxide sulfate compounds found in cement. Incorporating alum into concrete is expected to enhance the aluminium and cement content. This research aims to investigate the technical properties of normal concrete when supplemented with alum. The technical properties under consideration include slump value and compressive strength, with a fixed mix proportion of cement: sand: gravel = 1:2:3. Alum is added in proportions of 2%, 4%, 6%, and 8% by weight of cement in the concrete mix. The findings of this present study indicate that the highest compressive strength is achieved in concrete specimens with 2% alum addition by weight of cement, reaching 35.629 MPa, while the corresponding slump value is 7.75 cm

Abstract

The Certificate of Feasibility of Function (SLF) is a crucial instrument to ensure building safety, comfort, and compliance; however, achieving public service targets in Pekalongan Regency still faces governance challenges. Digitalization through the Building Management Information System (SIMBG) and support from the Expert Professional Team (TPA) is considered strategic for enhancing service effectiveness. This study aims to analyze the effect of SIMBG implementation on the effectiveness of SLF public services, with TPA support as a moderating variable. An explanatory quantitative approach was employed, surveying 120 respondents, including SLF applicants, service providers, and TPA members. Data were analyzed using structural equation modeling (SEM-PLS) to examine the relationships among variables. The results indicate that SIMBG implementation has a significant positive effect on user satisfaction (β = 0.46; p < 0.01), while TPA support strengthens this relationship (β = 0.31; p < 0.05). The integration of SIMBG and TPA proved effective in enhancing accountability, accelerating service processes, and reducing policy-practice gaps. However, procedural consistency and human resource limitations at the operational level remain. In conclusion, improving SLF service targets requires an integrated approach with SIMBG as a technological enabler and TPA as a professional enabler. Recommendations include enhancing digital literacy among officials, refining technical regulations, and strengthening the role of TPA in procedural assistance. This study is limited to the context of Pekalongan Regency; thus, generalization should be cautious, and future research is recommended to expand locations and include additional variables such as leadership and central regulations to enrich the understanding of SLF governance in Indonesia.

Abstract

Seismic safety is an essential consideration in the assessment and redesign of multi-story buildings in Indonesia because structural systems must accommodate earthquake-induced lateral forces while maintaining adequate strength and serviceability. Griya Kos Diponegoro in Semarang is a four-story reinforced-concrete residential building constructed in 2023 and originally designed according to SNI 1726:2012, necessitating reassessment based on the updated SNI 1726:2019 provisions. This study aims to evaluate the seismic response and redesign the upper structural components consisting of reinforced-concrete beams, columns, and slabs. A quantitative structural analysis approach was applied through three-dimensional modeling in ETABS, incorporating response spectrum and equivalent static analyses based on SNI 1726:2019, while reinforced-concrete design followed SNI 2847:2019 and gravity loading followed SNI 1727:2020. The building was modeled using a Special Moment Resisting Frame system on a soft-soil site classified as SE. Modal analysis using 15 modes achieved 100% combined mass participation in both principal horizontal directions, with the first two modes dominated by translational behavior and the third mode by rotational behavior. The design period adopted in the period-check procedure was 0.521 s. Story-drift evaluation indicated that the maximum drift occurred at Floor 2, reaching 29.420 mm in X and 29.348 mm in Y, below the permissible limit of 53.846 mm. The redesign produced member configurations for beams, columns, and slabs that satisfied the evaluated design requirements.
