Enhancing the seismic performance of multi-story buildings in high-seismic regions requires effective structural control systems to improve lateral resistance and energy dissipation. This study evaluates the influence of steel bracing and Fluid Viscous Damper (FVD) systems on the dynamic response of a 10-story regular building using Response Spectrum Analysis in structural analysis software, in…
This study aims to evaluate the seismic performance of a multi-story building structure with the application of Fluid Viscous Dampers (FVD) as an energy dissipation system. Indonesia, particularly the Bengkulu region, is located in a high seismic hazard zone, making earthquake-resistant structural design an essential requirement. In this research, a multi-story building was modeled using SAP200…
This research addresses the challenge users face in discovering board games that align with their preferences, particularly when those preferences are expressed descriptively in text. Traditional recommendation systems often struggle to capture the semantic nuances within natural language queries and effectively balance these with specific attribute criteria. To overcome this limitation, this s…
The open-pit mining system is used to extract thick coal seams and is carried out in stages using benches. This method is important due to its efficiency in exploiting large-volume resources. However, the low wall slope at PT. Banyan Koalindo Lestari, particularly in the North Pit, shows potential instability due to ongoing mining activities and varying geological conditions. To address this is…
Fluctuations in coal prices pose a challenge for companies in optimizing the economic value of mining operations. In response, PT Bukit Asam Tbk has proposed two new boundaries for the design of a new pit in Pit 2 Banko. This study aims to design a new pit based on the proposed boundaries, plan the forecast of excavation and hauling equipment to determine the annual production until the end of …
Pabrik pembuatan Asam Laktat dengan kapasitas produksi 100.000 ton/tahun ini direncanakan berdiri pada tahun 2029 di daerah Industri Gresik, Kec. Manyar, Kabupaten Gresik, Provinsi Jawa Timur, Indonesia dengan perkiraan luas area sebesar 19,10 Ha. Bahan baku untuk pembuatan Asam Laktat adalah Gliserol, KOH dan Karbon dioksida.

Pencemaran logam berat seperti ion logam Cu²⁺, Fe³⁺, dan Pb²⁺ yang berasal dari aktivitas laboratorium telah menjadi isu lingkungan yang serius karena sifatnya yang toksik dan dapat terakumulasi secara biologis. Penelitian ini bertujuan untuk mengevaluasi efektivitas adsorpsi bentonit alami dan bentonit yang diaktivasi secara kimia menggunakan H₂SO₄, kemudian dilanjutkan dengan per…
This study aims to analyze the performance of thorium nitride (ThN) fuel with varying uranium-233 enrichments in the core of a Gas-Cooled Fast Reactor (GFR) using OpenMC simulations. Burn-up calculations were performed over a period of 10 years with enrichment levels ranging from 0 to 12. The results show that the k-infinite value tends to increase at enrichments between 0–6, although it rema…
Risk assessment is a very important assessment for buildings, especially tall buildings in order to anticipate if there is a danger such as lightning strikes or more voltage in the building. In this study, we aimed to create risk assessment software using Python programming language to calculate R1, R2, R3 dan R4 and analyze a building to avoid the danger of lightning strikes based on IEC 62305…
