Abstract

Digital transformation enhances public service and government efficiency. Indonesia’s One Data Regulation supports integrated and quality data management. This qualitative policy study examines the implementation of the Cirebon One Data Policy using George C. Edward III’s framework (communication, resources, disposition, bureaucratic structure). Data were collected through interviews with Cirebon City DKIS officials. Findings indicate suboptimal implementation. Communication delays hinder data updates. Limited human resources and overlapping roles affect efficiency. Although data guardians show strong commitment, lack of sanctions weakens enforcement. Bureaucratic challenges arise from changing standards and limited data use. Despite efforts like technical training and evaluations by DKIS, several issues impede effective implementation. Improved coordination, enforcement mechanisms, and resource allocation are needed to optimize the Cirebon One Data Policy.

Abstract

Road safety is an important issue in land transportation, with the number of accidents in Indonesia increasing as the number of roads and vehicles increases. This study aims to evaluate the suitability of the geometric design of bends on the Cisumdawu Toll Road at KM 202-208 with the latest standards that can accommodate the safety and comfort aspects of road users. The bend design generally refers to the old standard  and is not fully compliant with Road Geometric Design Guidelines  (PDGJ 2021). There are significant differences between existing data and idealized calculations, especially in vehicle comfort. Therefore, design improvements, such as spiral and superelevation lengths, as well as safety facilities, are highly recommended to optimize road geometric performance and improve the safety of toll road users.

Abstract

This study explores the role of Spiritual Quotient (SQ) in adopting Islamic e-wallets using the Technology Acceptance Model (TAM) approach. The data for this research were obtained from 130 Gen Z Muslim users of Islamic e-wallets in Central Java, Indonesia. The research data analysis employed Partial Least Squares Structural Equation Modeling (PLS-SEM). The findings of this study reveal that spiritual quotient and perceived benefit have a positive and significant influence on the intention to use Islamic e-wallets. However, perceived usefulness and perceived ease of use do not significantly affect the intention to use. Through this research, Islamic e-wallet service providers can further enhance system performance, effectiveness, and ease of use to build higher service credibility.

Abstract

Digital transformation in banking is crucial for enhancing employee competencies, especially in marketing roles, amid rapid technological changes. However, challenges such as limited digital literacy, restricted access to learning platforms, and low participation in online training hinder employees' ability to meet the demands of the digital banking sector. This study explores how digital literacy, learning access, and participation affect marketing staff competencies at PT. Bank XXXX, with integrated learning systems utilization. Using a quantitative approach, data from surveys, interviews, and documents are analyzed. The research conducted from October 2024 to June 2025, show that improving digital literacy, access to learning resources, and participation positively impact competencies, with integrated learning systems strengthening these effects, supporting the bank’s digital transformation.

Abstract

The sustainability and growth of a company are strongly determined by its ability to generate profits. One key metric used to evaluate profitability is Return on Assets (ROA). To remain competitive and resilient, companies must regularly monitor and analyze their financial performance, including identifying the factors that influence ROA. This study examines the relationship between ROA and several financial indicators, namely the current ratio (CR), debt-to-asset ratio (DAR), total asset turnover (TATO), and sales growth (SG). The research utilized regression analysis on a sample of five companies within the Indonesian telecommunications subsector that met specific criteria during the 2016–2023 period. The findings reveal that sales growth does not significantly impact ROA, whereas current ratio, debt-to-asset ratio, and total asset turnover have a significant effect. The model explains 75% of the variance in ROA, with the remaining 25% attributed to other unexamined variables. These results suggest that asset efficiency, liquidity, and solvency are critical factors influencing the profitability of telecommunications companies, while sales growth alone does not directly enhance the ability to generate net profit from assets.

Abstract

This study aims to analyze the capacity of the Cijangkelok River downstream in facing the planned flood discharge, with a hydraulic modeling approach using HEC-RAS software. Maximum daily rainfall data from five rainfall stations during the 2014-2023 period was used as the basis for calculating flood discharge using the Rational method and Nakayasu Synthetic Unit Hydrograph (HSS). The calculation results showed that the peak flood discharge for the 10, 25, and 50-year return periods reached 599.71 m³/det, 648.91 m³/det, and 682.82 m³/det using the Rational method, and 835.01 m³/det, 888.68 m³/det, and 922.90 m³/det using the Nakayasu HSS method, respectively. Flow simulations with HEC-RAS indicated that some river cross sections, especially at STA 27+950, 28+050, and 28+100, were unable to accommodate the maximum discharge, causing runoff outside the channel. This finding indicates that the capacity of the existing channel is not adequate to safely channelize flood flows. The results of this study are expected to serve as a technical reference in river normalization planning and more targeted and sustainable flood mitigation efforts.

Abstract

This study discusses the comparison of cost and time efficiency between precast and conventional concrete systems in the structural work of building construction. The research adopts a quantitative comparative approach on two segments of the Sartikaasih Bhayangkara Hospital project in Bandung. The BoQ calculation results show that the precast system incurred lower total costs, amounting to IDR 17.6 billion (A1) and IDR 12.74 billion (A2), compared to the conventional system with IDR 19.86 billion (A1) and IDR 14.29 billion (A2). In terms of time, the precast system demonstrated significant efficiency, with savings of 65.02% on A1 and 21.43% on (A2). This efficiency contributes to the reduction of indirect costs and the risk of project delays. These findings indicate that the precast system can serve as a more economical and efficient alternative for building construction projects.

Abstract

Construction project efficiency is the key to success amid budget pressures and cost inflation. Value Engineering (VE) is a systematic solution to balance cost, reliability, and project performance. Pareto analysis identified four main works for optimization: walls, frames, floors, and ceilings with cost/worth ratio >1. Alternative solutions included AAC/HEBEL walls, PVC sills, unpolished homogenius tile, and PVC ceiling. The implementation of Value Engineering resulted in significant savings in walls (38.63%), frames (24.21%), ceilings (46.62%), and floors (39.74%). The total savings reached Rp1.481.761.485,10 (38,52% of the initial cost), with Life Cycle Cost as the main consideration.

Abstract

This study aims to explore the application of Lean Construction methods to reduce waste in construction projects in West Java. Inefficiencies often arise from seven types of waste: waiting, inventory, motion, overproduction, inappropriate processing, transportation, and defects. Data were collected through a quantitative approach, by distributing questionnaires to construction experts in the West Java region. Data analysis utilized a Likert Scale to determine the intensity level of each waste category. From 14 respondents, the two highest waste categories were Waiting (weather disturbances) and Transportation (the distance of suppliers to the project site). Root cause analysis was conducted using the 5 Why method with experienced respondents. The main issues identified were poor planning, inefficient logistics, and improper supplier selection.
