Currently, BIM has been widely applied in structural design and construction management work. However, there has not been much BIM implementation in evaluating existing structures. Thus, BIM was implemented in this study to evaluate the structural capacity and seismic responses of low-rise buildings due to earthquake loads. The case study was conducted on the Pakubuwono X Mosque building, designed in 2017 based on SNI 2847:2013, SNI 1726:2012, and SNI 1727:2013. This research was carried out numerically by involving the interconnection of Autodesk Revit and Autodesk Robot SAP software, which worked within the BIM framework. The structural model of the Pakubuwono X Mosque building was developed using Autodesk Revit, which was connected to Autodesk Robot SAP for analysis and structural design processes. Furthermore, the design products of Autodesk Robot SAP are reconnected with Autodesk Revit to be integrated with architectural and MEP (mechanical, electrical, and plumbing) design products. In this study, the structural capacity evaluation was carried out on the floor slabs, beams, and columns. Furthermore, the seismic response in the form of modal participation mass ratio, fundamental period, base shear, and story drift are also reviewed in this study. In conclusion, all structural elements (floor slabs, beams, and columns) are adequate to support the design load as indicated by the demand-capacity ratio (D/C Ratio), which is less than 1.0. Furthermore, all parameters of seismic response reviewed in this research comply with the requirements set out in SNI 1726:2012.

Most of the seismic damage of existing traditional buildings is due to the absence of practical beam and column structures as the main reinforcement of the building. While a masonry wall as a structural component is commonly negligible due to their relatively low strength in contributing to the frame structure. As a result, when the earthquake struck, the building collapsed, and the ruins of building elements hit the occupants seriously and caused many deaths. This paper presents the results of preliminary research on the experimental investigation of interlocking concrete block for the masonry wall applied to non-engineered earthquake-resistant buildings. The interlocking between concrete blocks is expected to contribute to the strength of the masonry wall in resisting the loads, either in-plane or out-of-plane directions. The novelty of this type of concrete block lies in the uniqueness of the interlocking shape, making it effective in withstanding the earthquake load. This research focuses on the testing of interlocking concrete block units in withstanding loads in the direction and perpendicular to the field and equipped with testing the compressive strength of the wall and diagonal shear strength. The results produce interlocking models of concrete block contribute to better strength than ordinary clay bricks for the masonry wall.

The level of electrical quality has become a necessity in supporting human activities, especially in voltage stability. To support the calculation of voltage stability, various load flow methods have been developed. Load Flow Analysis is very important in planning and implementation in designing future power system expansion and in determining the best operation of the existing system. The tools for calculating simulation based power flow are the Power Tool Analysis Toolbox (PSAT) and the Transient and Electrical Analysis Program (ETAP). This paper discusses the comparison of the performance of the two load flow simulation tools, PSAT and ETAP. The Gandul Substation network data in Indonesia in April 2019 with a load of 15.37 MW is used for simulations. Load flow analysis is performed using Newton Raphson method with a network of 11 buses (150 kV, 20kV). The simulation results show that PSAT has a deviation of about 0.663% to the Bus Voltage from GIG and ETAP simulation has a deviation of about 0.562% to the Bus Voltage from GIG.

<p>Bencana gempa bumi merupakan salah satu hal penting yang harus diperhatikan pada beberapa kawasan di Jawa Tengah, tak terkecuali di Desa Tohudan, Karanganyar-Jawa Tengah. Banyak kerugian yang terjadi akibat dari bencana gempa bumi, untuk meminimalisir kerugian yang ditimbulkan dari bencan gempa bumi, maka hal yang harus dilakukan adalah melakuakan mitigasi bencana gempa bumi. Salah satu kegiatan yang dapat dilakukan adalah peningkatan pengetahuan masyarakat terhadap bahaya gempa bumi itu sendiri. Jurnal ini memuat kegiatan yang bertujuan untuk memberikan pengetahuan kepada masyarakat tentang gempa bumi. Kegiatan awal yang direncanakan adalah sosialisasi secara online, namun mengingat kasus positive Covid 19 yang belum reda, maka tim memutuskan untuk mengganti sistem dengan cara penempelan Poster dibeberapa lokasi di Desa Tohudan. Metode yang dilakukan pada kegiatan ini adalah persiapan media pembelajaran untuk peningkatan pengetahuan masyarakat, diskusi yang dilaksakana dengan perangkat desa, sosialisasi yang diganti dengan pembuatan desain poster, dan yang terakhir adalah penempelan poster. Kegiatan ini diharapkan dapat memberikan informasi kepada masyarakat terkait dengan mitigasi gempa bumi, sehingga kerugian yang terjadi akibat bencana dapat diminimalisir.</p>
