Abstract

This study examines the implementation of Indonesia’s digital education policy through the e-Rapor system in a rural public high school, SMAN 1 Abung Tinggi, using a qualitative descriptive case study approach. Drawing on in-depth interviews, non-participant observations, and document analysis, the research analyzes e-Rapor as a socio-technical instrument embedded in organizational routines rather than as a standalone technological application. The findings show that e-Rapor improves administrative efficiency, data integration, and reporting accountability, while simultaneously reshaping assessment practices, professional roles, and internal coordination mechanisms. Implementation outcomes are strongly mediated by human resource capacity, leadership practices, infrastructural constraints, and informal adaptive arrangements developed at the school level. Digital literacy gaps and unstable connectivity remain persistent challenges, yet peer collaboration and managerial support enable functional policy adaptation. The study demonstrates that digital policy effectiveness in rural contexts emerges from institutional mediation and organizational learning, not from technological deployment alone. Theoretically, the research contributes to policy implementation and digital governance by highlighting adaptive compliance, while methodologically it demonstrates qualitative inquiry for capturing contextualized dynamics.

Abstract

This study examines the empirical implementation of e-procurement within the Procurement Service Unit (UKPBJ) of the Directorate General of Corrections in Lampung, focusing on accountability, effectiveness, and transparency outcomes. Utilizing a qualitative descriptive approach, data were collected through in-depth interviews, non-participant observation, and document analysis, while analytical validation employed triangulation and the interactive model of data reduction, display, and iterative conclusion verification. Findings indicate that digital systems such as SPSE, e-catalogue, and INAPROC have substantially improved traceability and procedural order in procurement activities, enabling more efficient supplier selection, contract management, and monitoring of procurement stages. Nevertheless, optimal outcomes are hindered by infrastructure disparities, limited human resource competencies, and inconsistent managerial support, which constrain uniform adoption and system utilization. Regulatory support and policy clarity significantly influence implementation success, while leadership and capacity-building emerge as pivotal enablers. The study contributes to e-procurement literature by empirically validating socio-technical determinants of digital procurement performance, highlighting the need for coordinated interventions in technological readiness, institutional governance, and personnel development to fully realize transparency, accountability, and efficiency objectives in public sector procurement

Abstract

This study presents the design and development of a real-time IoT-based monitoring security system for home safes integrated with Telegram Bot notifications. The proposed system employs NodeMCU ESP8266 as the main controller, combined with an HC-SR04 ultrasonic sensor for motion detection and an MPU-6500 vibration sensor for shock recognition. When suspicious movement or abnormal vibration is detected, the system activates a local buzzer alarm and triggers an automatic solenoid door lock mechanism through a relay module. Simultaneously, warning messages are transmitted instantly to users via Telegram Bot and displayed on a web-based monitoring dashboard. Experimental evaluation indicates that the ultrasonic sensor achieved an average measurement error of ±1.6 cm, while vibration detection responded within 0.2–0.5 seconds. The solenoid locking mechanism demonstrated 100% success across all test scenarios. Telegram notifications were delivered with an average latency of 1.33 seconds, depending on network quality. The optimization stage improved detection stability, reduced false alarms, and enhanced system reliability. Overall, the developed prototype offers an effective and low-cost smart security solution for domestic safe protection.

Abstract

This study evaluates the performance of Asphalt Concrete-Wearing Course (AC-WC) mixtures incorporating shell waste and waste glass as additives for sustainable pavement applications. The optimum asphalt content was determined at 5.8% using the Marshall method, producing balanced volumetric and mechanical properties that satisfy heavy traffic specifications. Waste glass addition without shell waste increased mixture stiffness but did not consistently achieve optimal stability due to volumetric imbalance. A synergistic effect was observed when shell waste and waste glass were combined. The mixture containing 5% shell waste and 5% waste glass demonstrated the most favorable performance, characterized by higher stability, proportional Marshall Quotient, controlled air void distribution, and improved structural integrity. Increasing shell waste content to 7.5% and 10% did not enhance performance and tended to reduce volumetric balance. Economic evaluation indicates a material cost reduction of approximately 1.72% per kilometer compared to conventional mixtures, without compromising mechanical performance. The findings confirm that the optimal incorporation of shell waste and waste glass is technically feasible and economically beneficial for sustainable AC-WC pavement construction.

Abstract

This laboratory-based quantitative experimental study evaluated the performance of Asphalt Concrete Wearing Course (AC-WC) modified with wood ash as filler and Expanded Polystyrene (EPS) styrofoam as asphalt additive. The research verified the base binder through penetration testing, yielding an average penetration value of 69.4, confirming the use of 60/70 penetration grade asphalt. Asphalt content was validated using extraction testing, resulting in an average binder content of 5.80%, ensuring consistency between design and actual mixture composition. Marshall testing was conducted to assess mechanical and volumetric characteristics, including stability, flow, Marshall Quotient (MQ), VMA, VIM, and VFB. The results demonstrated that EPS dosage significantly influenced volumetric balance and load resistance within the mixture. Among the evaluated combinations using 4% wood ash and EPS levels of 0%, 0.5%, 1%, and 1.5%, the optimum performance was achieved at 1.5% EPS, which satisfied key Bina Marga 2018 Revision 2 requirements for VIM, VMA, VFB, stability, and flow. However, MQ values remained below specification for all mixtures, indicating limitations in stiffness–deformation ratio and the need for further optimization and durability testing.

Abstract

Overburden transportation constitutes a critical stage in open-pit mining operations, characterized by a high level of safety risk and a direct influence on production continuity. This study aims to evaluate the implementation of Occupational Safety and Health (OSH) in overburden hauling activities from the mining front to the disposal area at PT X, Lahat Regency, South Sumatra. The research employed a descriptive design integrating qualitative and quantitative approaches. Data were collected through field observations, interviews with relevant stakeholders, questionnaires administered to workers and heavy-equipment operators, and hazard identification alongside risk assessment using the Risk Assessment Matrix. The findings indicate that OSH implementation at PT X can be classified as satisfactory, as reflected in the high level of compliance with personal protective equipment usage, routine safety briefings, adequate safety signage, and active supervision by OSH personnel. Risk analysis shows that most hauling activities fall within low to moderate risk categories, although several hazards still require additional control measures. Overall, the OSH system in overburden transportation operates effectively; nevertheless, continuous evaluation remains essential to enhance operational safety and further reduce accident potential.

Abstract

This study evaluates the operational synchronization between loading and hauling equipment in overburden stripping activities at PT XXY, South Sumatra, using an empirical field-based approach conducted from April to June 2025. The system architecture consists of one excavator and several Off Highway Trucks operating within a single active mining front. Primary data were obtained through direct cycle time measurements of at least 30 representative cycles per unit, supported by secondary technical parameters including bucket capacity, swell factor, hauling distance, and effective working hours. Productivity analysis indicates an initial output of 367.81 BCM/hour with a match factor of 0.96, reflecting capacity imbalance and excavator waiting time. Simulation of fleet adjustment to eight hauling units increased productivity to 420.36 BCM/hour and improved system balance while reducing specific fuel consumption from 0.41 to 0.37 liter/BCM. Efficiency evaluation demonstrates that synchronization directly influences operational utilization, energy intensity, and production target achievement.

Abstract

This study investigates the comparative efficiency of conventional cast-in-situ and steel deck methods for bridge deck slab construction in the Kapuk–Teluknaga–Rajeg Toll Road Project Phase I, Banten Province, Indonesia. The research applies a field-based empirical case study design with a quantitative approach, using primary data from site observations and structured interviews, and secondary data from shop drawings, project specifications, and cost documents. Cost estimation was conducted using unit price-based analysis following AHSP standards regulated by Permen PUPR No. 28/PRT/M/2016, while construction duration was calculated based on actual productivity and activity sequencing. The results indicate that the conventional method required 17 working days with a total cost of Rp 592,003,970, whereas the steel deck method required only 8 working days with a total cost of Rp 553,984,460. These findings demonstrate that steel deck provides a 52.94% reduction in construction time and a 6.42% cost saving. The study further shows that steel deck shifts project cost structure from labor-intensive operations to controlled material-based execution, improving schedule reliability and construction productivity.

Abstract

Asphalt Concrete Wearing Course (AC-WC) road pavement functions as a crucial wearing layer to maintain its performance and service life, but conventional asphalt still faces problems with its high cost and dependence on non-renewable natural resources. Therefore, this study analyzes the use of palm kernel shell waste and dammar resin as a modified AC-WC mixture, looking at its Marshall characteristics and suitability to Bina Marga specifications. The method used is an experimental laboratory with variations of palm kernel shells of 0%, 2.5%, 5%, 7.5% plus dammar resin of 0%, 2%, 4%, and 6%. Marshall tests check stability, flow, VIM, VMA, VFA, and MQ according to SNI and Bina Marga. The results show that the addition of both has a positive effect, with the optimum at 7.5% palm kernel shells and 6% dammar resin increasing stability and meeting technical standards, making it highly potential as an environmentally friendly and cost-effective alternative
