Abstract

Most of the Polytechnics in Indonesia currently function as workshops/labs/studios only as places for students to practice. As a result, student practice becomes a cost center for the cost of materials, maintenance, and development of practical machines, because the products produced by students do not meet industry standards to be worthy of sale. So, research was conducted to make a feasibility assessment of the practical steel construction materials at Civil Engineering PNJ to produce a product that is feasible to sell. The method used is testing the material properties of steel construction because of student practice and conducting a feasibility analysis of the steel construction material by comparing it to the quality standards in SNI. The results of material properties testing, and material feasibility assessment of steel construction can be concluded that the steel profile and connection plate used meet the quality standards with the BJ 55 and BJ 41 classifications, while the bolts used only meet the standard A370 bolt classification. So, it is recommended to use bolts with high quality bolt classification to meet the quality standards that exist in the industry.

Abstract

One alternative to replacing traditional red brick is lightweight brick, which is commonly used as a wall construction material. One of its main advantages is its light weight, which can help reduce overall construction costs. The reduced weight of the wall material allows for a decrease in the volume of structural elements needed. However, with advancements in material technology, there is a need to further improve the efficiency of lightweight bricks in terms of material usage and the quality of the masonry, particularly its shear strength. This research aims to analyze the optimal fiber placement composition in Cellular Lightweight Concrete (CLC) bricks to enhance the bond strength between bricks compared to that of standard lightweight brick masonry. The test specimens were constructed by assembling wall segments using lightweight bricks measuring 7.5 cm × 20 cm × 60 cm. Compressive strength and horizontal shear strength tests were then conducted on the CLC brick wall assemblies. The results showed that the lightweight bricks had a compressive strength of f'c = 1.07 MPa. The horizontal shear strength without fiber reinforcement was fg = 0.09 MPa, while with fiber reinforcement, it decreased to f'g = 0.06 MPa. Crack patterns were observed at failure displacements of 0.33 mm (non-fiber) and 0.5 mm (with fiber). These findings indicate that the use of GRC fiber in lightweight brick walls resulted in lower horizontal shear strength and displacement performance.

Abstract

Abstrak   Beton merupakan material getas yang mempunyai kuat tekan tinggi, namun memiliki kuat tarik rendah.  Kelemahan ini dapat diantisipasi dengan penggunaan serat sebagai micro reinforcement pada beton. Penelitian ini menguji karakteristik beton Self Compacting Concrtete (SCC) dengan campuran 5% Abu Sekam Padi (ASP) yang diberikan tambahan berbagai dosis serat limbah Scrap Baja, yaitu 0%, 0,25 %, 0,50 %, 0,75% , dan 1% dari berat beton. Pengujian Kuat Tekan, Kuat Tarik Belah, Tegangan-Regangan, dan Modulus Elastisitas dilakukan dengan menggunakan benda uji silinder beton diameter 15 cm, tinggi 30 cm. Sedangkan, Kuat Lentur beton diuji dengan benda uji balok berukuran 10 cm x 10 cm x 100 cm. Hasil penelitian menunjukkan bahwa penggunaan ASP sebesar 5% dan limbah serat baja sampai dengan 0,75% dapat meningkatkan Kuat Tekan, Kuat Lentur, Kuat Tarik, Modulus Elastisitas, dan Regangan maksimum pada beton.   Kata kunci: Serat Limbah Scrap Baja, Abu Sekam Padi, Kuat Tekan, Kuat Lentur, Modulus Elastisitas   Abstract   Concrete is a brittle material with high compressive strength but low tensile strength. This weakness can be addressed by adding fibers as micro-reinforcement within the concrete mixing. This research investigates the characteristics of Self-Compacting Concrete (SCC) with a 5% Rice Husk Ash (RHA) mixture, supplemented by varying dosages of waste steel scrap fibers: 0%, 0.25%, 0.50%, 0.75%, and 1% of the concrete weight. Compressive Strength, Split Tensile Strength, Stress-strain behavior, and Modulus of Elasticity were tested using cylindrical concrete specimens with a diameter of 15 cm and a height of 30 cm. Additionally, the Flexural Strength of the concrete was evaluated using beam specimens 10 cm x 10 cm x 100 cm. The results indicate that the addition of 5% RHA and steel fiber waste up to 0.75% can significantly enhance the compressive strength, flexural strength, tensile strength, modulus of elasticity, and maximum strain of the concrete.   Keywords: Fiber of streel scrap waste, Rice Husk Ash, Compressive Strength, Flexural Strength, Modulus of Elasticity

Abstract

The suitability between expectations and reality of the quality of education students get during college affects students' perceptions of education quality in a study program. Information on the achievement of the implementation of main courses subjects and the teaching and learning process can be used as a basis for evaluating and mapping the gaps between the curriculum and the teaching and learning process with the required competencies. This study aims to determine students' perceptions of core subjects' learning outcomes in the D3 KS and D3 KG Pograms, Department of Civil Engineering PNJ. The method used in this research is the survey method, with purposive random sampling and descriptive analysis approach. Meanwhile, the performance and gap analysis use the Importance-Performance Analysis (IPA) method. The results denote that the students' perceptions of the learning outcomes of the main courses of the D3 KG and D3 KS Programs, Department of Civil Engineering PNJ showed promising results. The IPA analysis shows that six of the seven D3 KG Study Program main courses are in Quadrant II, and six of the eight D3 KS Program main courses are also in Quadrant II.

Abstract

The application of high-performance strength concrete (HPSC) in precast beam systems is gaining attention as a means to enhance construction efficiency and structural performance. Previous studies, such as those by Graybeal, have demonstrated the effectiveness of ultra-high-performance concrete (UHPC) in precast bridge deck applications. Similarly, materials like epoxy grout, epoxy-based grout, and rapid-set concrete have shown favorable properties for accelerating construction processes and improving durability. This research aims to evaluate the feasibility of using HPSC in precast beam connections, specifically to reduce the required length of reinforcement at the joint. The goal is to develop a system that can be effectively implemented in global construction practices. The study investigates a precast beam system using HPSC and compares it to a conventional cast-in-place beam. The focus is on key performance metrics including deflection, ultimate load capacity, and ductility. The influence of compressive strength on reinforcement length reduction is assessed in reference to ACI guidelines, which suggest that higher concrete compressive strength allows for shorter rebar development lengths. The precast beam (P1) utilizing the HPSC system achieved a compressive strength of fc’ = 44.81 MPa at the connection. Compared to the conventional beam (K1), P1 showed improved structural behavior, with a reduced deflection of 40.11 mm at an ultimate load of 110.02 kN, whereas K1 exhibited a deflection of 138.11 mm at an ultimate load of 113.82 kN. The ductility of the HPSC system was measured at 4.81, indicating enhanced deformation capacity under load. The findings confirm that the use of HPSC in precast beam connections not only meets structural requirements but also contributes to a reduction in reinforcement length. This supports faster and potentially more costeffective construction, aligning with global needs for innovative and efficient building practices.
