Abstract

Kegagalan struktur dapat berdampak buruk pada tingkat kenyamanan struktur. Penting untuk mengetahui perilaku struktur akibat beban yang ditopang karena dapat membantu memprediksi kekuatan struktur dan kenyamanan struktur yang sedang dikerjakan. Salah satu cara untuk mengetahui dan memprediksi kekuatan dan kenyamanan struktur akibat beban yang diterima adalah dengan melakukan pengujian laboratorium dan simulasi. Simulasi VecTor2 digunakan untuk memprediksi gaya geser, retak, dan displacement yang terjasi pada balok beton bertulang pada saat diberikan beban perpindahan. Tegangan ikatan (bond-slip) memberikan pengaruh yang besar terhadap kekuatan dan respon histeris pada balok tipe A1 dan A2. Oleh karena itu, penelitian ini juga mengkaji pengaruh bond-slip terhadap kekuatan balok beton bertulang. Seluruh hasil simulasi VecTor2 dengan menggunakan bond stress-slip effect akan dibandingkan dengan hasil pengujian eksperimen untuk melihat keakuratan simulasi VecTor2. Pada penelitian ini diperoleh nilai bond-slip 0,08 dan perbandingan nilai rasio untuk semua beban puncak antara 1,05 dan 1,06.

This is one of the objectives of the Faculty of Engineering's Community Service (PKM) which is held at the HKBP Ressort Perumnas Klender Church. The activities carried out are drawing as-built drawings in 2-D and 3-D and checking the structure in the development plan for the HKBP Ressort Perumnas Klender Church, where the Church can use these drawings for the development and improvement of the Church in the future. The method used in this PKM is to inspect and measure existing buildings in the field, draw floor plans for the 1st and 2nd floors of the church, and then draw plans for the development of the church, as well as 3-D drawings. Apart from that, checks were also carried out on the existing church structures (columns, plates, beams), which would later be used in the development of new church buildings in the church consistory area. The results of this PKM are 2-dimensional and 3-dimensional church development plans as well as an analysis of the building structure from an architectural and civil perspective.

Abstract

The earthquake that occurred in the Cianjur area, West Java on Monday 21 November 2022 at 13.21 WIB resulted in 635 fatalities and 56,000 houses that were damaged. The results of the assessment found that many houses and public facility buildings still did not meet the requirements for earthquake-resistant buildings, especially in the use of concrete materials, main reinforcement, stirrups in columns, beams, foundations and beam-column joint, and did not have a strong column-weak beam planning concept. This can be seen from the inability of the column to withstand/ carry the working load which causes the column to collapse and damage. Therefore, it is very necessary to pay attention to building planning in Disaster Prone Areas (DPA) in accordance with earthquake resistant building regulations SNI 1726:2019 and SNI 2847:2019

Abstract

The building façade must be carefully designed from the early planning stage. Given the wide variety of single-glazed glass types, selecting an appropriate glass façade is not a simple task. In practice, glass selection is generally based solely on cost considerations. This study proposes a glass façade selection method that incorporates comfort performance as a primary criterion. In addition to comfort, physical properties and cost factors are also considered. The comfort parameters evaluated in this study include thermal comfort and visual comfort derived from the glass properties. A total of fifty-five (55) single-glazed glass samples, consisting of float glass, tinted glass, and reflective glass, were analyzed. The results indicate that the proposed method can effectively support glass façade selection. For float glass, increasing glass thickness leads to improved comfort performance. For tinted glass, green-colored glass with a thickness of 6 mm exhibits the best comfort performance with a value of 6.6. Meanwhile, for reflective glass, classic green reflective glass achieves the highest comfort performance value of 7.0 at a thickness of 6 mm. Among all single-glazed glasses (tinted and reflective) with a thickness of 6 mm, classic green reflective glass demonstrates the best overall comfort performance.

Abstract

This study aims to develop an environmentally friendly construction material by partially substituting cement and sand with rice husk ash (RHA) and fly ash in pervious concrete. The combination of these two pozzolanic materials is expected to enhance the porosity of the concrete without causing a significant reduction in compressive strength, thereby maintaining its functionality while supporting rainwater conservation in urban areas. The experimental program consisted of a control concrete (without additives) and three modified mixes containing 10%, 15%, and 20% of combined pozzolanic materials (RHA and fly ash) as a partial replacement of the total binder, with a water–cement ratio (w/c) of 0.5 and up to 80% reduction in sand content. The results indicate that increasing the pozzolanic content proportionally increases the porosity and water absorption, from 5.9% in the control mix to 9.8% in the highest variation. Despite the higher porosity, the compressive strength remained within the range of 22–27 MPa, which satisfies the requirements for non-structural concrete. This demonstrates that RHA and fly ash can effectively replace a substantial portion of cement without significantly compromising performance. The pozzolanic reaction between active silica and Ca(OH)₂ generated secondary C–S–H gel formation, which strengthened the microstructure surrounding the pores. Overall, the incorporation of RHA and fly ash in pervious concrete produces a material with a balanced combination of strength, porosity, and environmental sustainability, offering great potential for application in sustainable drainage systems, permeable pavements, and urban green infrastructure. Keywords: Green Concrete; Rice Husk Ash; Fly Ash; Porosity; Compressive Strength; Pozzolanic Reaction; Sustainable Infrastructure.

Abstract

This study is a literature review that compares the performance of recycled asphalt mixture or Reclaimed Asphalt Pavement (RAP) modified with three types of waste materials, namely waste oil, used cooking oil (WCO), and styrofoam plastic waste. An analysis was conducted on 13 scientific journals that discussed the influence of the three materials on technical parameters such as Marshall stability, flow, Marshall Quotient (MQ), and mixed durability. The results of the study show that used cooking oil (WCO) is the most optimal and environmentally friendly feedstock, as it is able to significantly increase the flexibility and durability of the RAP mixture at the ideal level of 3–6%. Used oil is also effective in restoring the aging properties of asphalt, but its use in excess amounts (>10%) can reduce its stability and resistance to water, and requires special handling because it is classified as B3 waste. Meanwhile, plastic waste such as styrofoam, PET, and LDPE are more suitable as additives to improve the structure and reduce the porosity of the mixture, although it does not function as the main contaminant. Of all the types of cooking materials used, used cooking oil (WCO) shows the most consistent performance according to Bina Marga 2010 specifications. Keywords: RAP, used oil, used cooking oil (WCO), styrofoam plastic waste

Abstract

A reinforcement concrete beam behavior is substantial to design structure. Some failures can found in the beam because the beam reinforcement structure does not install like procedure design, this problem made failure for the structure. Knowing the behavior of the beam structure resulting from the load is necessary, as it can help to predict the strength of the structural beam and comfort of the structure being worked on. To find out and predict the strength and comfort of the structure reinforced concrete beam as a result of the load received is the experimental test and simulation. The simulation VecTor2 was used to predict the shear force, crack, and displacement of the reinforced concrete beam when applied to the displacement load. This simulation considered the effect of the bond stress-slip effects of behavior reinforced concrete. Bonds stress-slip (0.139) gives a substantial influence on the strength and hysteretic response of the reinforced concrete beam. That is why this study considers the effect of the bond stress-slip on reinforced concrete. The results of the experiment test and simulations performed, the ratio of load capacity ranges from 1.00-1.095, and the crack pattern forms an angle of 45. All the results of simulation VecTor2 using the bond stress-slip effect would be compared with the result of the experimental test to see the behavior and accuracy of the simulation test.
