East Jakarta as a whole has a population of 3,314,396 people. I The ratio of vehicle volume to road capacity of the case study of Jalan Kesehatan, Pasar Rebo District, East Jakarta is an alternative road to Cijantung, Ciracas, and the flyover. Traffic on this health road section began to show signs of congestion due to high vehicle volume, an increase in the number of vehicles in the city that caused changes in traffic behavior, theoretically there is a fundamental relationship between traffic flow, speed, and density. The purpose of this study is to determine the level of service of the Health road section. The method used in this study is the survey method, namely conducting analysis and using the 2023 Indonesian Road Capacity Guidelines (PKЛ). Based on the analysis results, it is known that the busiest traffic volume value occurred on T on Monday, July 22, 2024 at 18.00-19.00 of (Q) 1893.9 pcu/hour with a free flow speed of 40.5428 km/hour and a health road capacity of 2330.7648 pcu/hour, which means that the capacity and traffic flow of this health road result in a decrease in the level of service. So the average degree of saturation (DJ) is 0.8 seconds/pcu, so it can also be seen that the level of service of the health road in Pasar Rebo District, East Jakarta is at level D.
Analisis Pengaruh Penambahan Serbuk Kaca Sebagai Campuran Agregat Halus Terhadap Kuat Tekan Dan Modulus Elastisitas Beton
The increasing demand for sustainable construction materials has prompted research into alternative materials, one of which is glass powder. This study evaluates the effect of adding glass powder on the compressive strength and modulus of elasticity of concrete. An experimental method was conducted with variations in glass powder content of 0%, 1%, 2%, 3%, and 4% by aggregate weight. The concrete was tested to determine its compressive strength and modulus of elasticity, with testing carried out at the Civil Engineering Laboratory. The results showed that the addition of 2% glass powder provided the optimal increase in compressive strength, reaching 20.75 MPa, compared to concrete without glass powder, which had a compressive strength of 17.27 MPa. The addition of 3% and 4% also improved compressive strength, though slightly lower than the 2% addition. Conversely, the 1% glass powder addition reduced the compressive strength to 10.82 MPa. The modulus of elasticity of the concrete increased significantly with the addition of 3% glass powder, reaching 2,924.670 MPa, which is higher than concrete without glass powder (2,353.373 MPa). The most significant increase occurred between 1% and 2% glass powder. However, with 4% glass powder, there was a slight decrease in the modulus of elasticity.
ANALISIS PENGARUH DILATASI BANGUNAN PADA GEDUNG 6 LANTAI BERDENAH L TERHADAP GEMPA DENGAN METODE RESPON SPEKTRA
Indonesia is one of the countries with a high frequency of seismic activity. The earthquakes that occur in Indonesia are caused by the vertical movement of two continental plates: the Indo-Australian and Eurasian plates. Furthermore, the island of Java is characterised by a multitude of active faults, which serve to elevate the risk of seismic activity in the region. Given the high potential for earthquakes in this region, it is crucial to prioritize earthquake-resistant construction planning, including the incorporation of dilatation techniques to mitigate seismic impacts. This research aims to elucidate the influence of building dilatation on a six-story L-plan structure subjected to seismic forces and ascertain the optimal dilatation gap distance for the Faculty of Engineering Building Center. The research method entails the analysis of the building structure using the ETABS program, with a comparison between structures with and without dilatation. The parameters analyzed include structural vibration period, inter-storey deviation, base shear force, and torsional irregularity. The calculation of the dilatation gap distance is carried out in accordance with the requirements of SNI 1726:2019. The findings of the analysis demonstrate that the implementation of dilatation in L-shaped buildings markedly influences the structural response to earthquake loads. The model with stiffer dilatation exhibited a smaller structural period of vibration and more restrained inter-storey deviation, while the model with more flexible dilatation demonstrated a larger period of vibration and larger inter-storey deviation. The safe dilatation gap distance of the Building Center building of the Faculty of Engineering was calculated to be 26 mm.
