The current study aimed to understand the condition of each stage of building construction, whether for existing or under-construction buildings, from design to execution, which is of paramount importance. Given the numerous damages that buildings and structures suffer as a result of errors and negligence, studying and documenting these structures in the form of practical guidelines, while cons…
This study presents the development and evaluation of a hybrid proportional–resonant and proportional–integral (PR–PI) controller for three-phase induction motor drives. The proposed control structure applies a proportional–integral controller in the outer speed loop to generate the torque reference, while a proportional–resonant controller is implemented in the inner current loop to …
Urban congestion and rising energy demand represent critical challenges for sustainable transportation development in rapidly growing metropolitan areas such as Jakarta. As a low-carbon public transport alternative, the Mass Rapid Transit (MRT) system plays an essential role in enhancing urban mobility while mitigating greenhouse gas emissions. Improving the aerodynamic performance of MRT train…
This study focuses on the lateral resistance capacity of free-head pile foundations subjected to horizontal loads, including earth pressure, wind, seismic, ship collision, column eccentricity, wave, and transmission tower cable loads. Previous studies have utilized finite element methods and specialized pile foundation programs to generate non-dimensional curves for estimating soil deflection a…
In the field of orthopedics, the tightness of screws in bone fixation is generally unknown. Improper fixation may affect fracture healing. The purpose of this study was to determine the torsional and shear strengths during bone fixation and to analyze bone damage induced by torsional and shear loads. The method used in this study was experimental, consisting of torsion and shear tests. Two bone…
Transportation Demand Omotenashi (TDO) is a transportation demand management approach that emphasizes the values of hospitality, familiarity, and warmth in urban mobility planning. This study aims to identify development priorities for the Tunjungan Corridor in Surabaya by applying the Omotenashi concept as a strategic effort to enhance both the area\\\'s identity and mobility quality. The stud…
The vacuum preloading method is widely used for improving the stability of soft clay when used as a foundation. The method offers many advantages, including increased consolidation rate and bearing capacity. This study was carried out in a laboratory model to investigate the effect of vacuum pressure on water content and pore-water pressure distribution, and hence, soil settlement. Preliminary …
Drought is a recurring challenge in agricultural regions that are highly dependent on seasonal Precipitation, including Lamongan Regency, East Java, Indonesia. This study aims to analyze drought conditions based on vegetation dynamics using the Normalized Difference Vegetation Index (NDVI) and its relationship with Precipitation variability. Monthly NDVI data for 2024 were derived from Landsat …
Coastal industrial zones in Indonesia are increasingly exposed to compound flood and sediment hazards driven by interactions between upstream discharge and tidal dynamics. This study aims to evaluate the extent of flood inundation and sediment transport processes in the Tanggok and Mireng sub-watersheds, which drain into the Java Integrated Industrial and Ports Estate (JIIPE) in Gresik, East Ja…
Octenyl succinic anhydride (OSA) starch has the potential to be used as an egg yolk replacer (emulsifier) in low-fat spread formulations, a relatively unexplored application compared to its conventional use in mayonnaise and salad dressings. This study elucidates the novel functionality of OSA starch in low-fat spread systems, offering a potential alternative to conventional emulsifiers associa…
