The rapid development of information and communication technology has encouraged military organizations to adopt modern systems capable of supporting operational effectiveness. One of the challenges faced by the Indonesian Marine Corps is the limitation of conventional monitoring methods that still rely on voice reports through tactical radios and manual communication systems. This condition often causes delays in information delivery, inaccuracies in troop positioning data, and difficulties in controlling personnel and logistics in dynamic operational environments. This study aims to formulate a conceptual model for the utilization of a GPS Tracking System integrated with Marine Corps communication equipment to improve troop and material movement monitoring. The study employed a Research and Development (R&D) method with a descriptive qualitative approach. Data were collected through literature review, observation, interviews, questionnaires, and documentation involving operational personnel and military communication experts. The results indicate that integrating GPS Tracking Systems with communication equipment can provide real-time location information, improve command and control effectiveness, accelerate reporting processes, enhance logistics supervision, and support operational evaluations through recorded movement data. The proposed concept is expected to strengthen situational awareness, increase operational efficiency, and support mission success in future Marine Corps operations.

This study aims to analyze a comparison of coal stockpile volumes using the DJI Mavic 3 Pro Unmanned Aerial Vehicle (UAV) method versus the truck count method at PT. Mitra Barito. Data collection was conducted through aerial photography using a UAV at altitudes of 60 meters and 70 meters, as well as Ground Control Point (GCP) measurements using GPS. The aerial imagery data was processed using photogrammetry software to generate orthophotos and a Digital Elevation Model (DEM), followed by a geometric accuracy test based on the Geospatial Information Agency Regulation No. 6 of 2018, using the Circular Error 90% (CE90) and Linear Error 90% (LE90) parameters. The research results show that high-quality processing at an altitude of 60 meters yields a CE90 value of 2.1619 meters and an LE90 value of 4.3656 meters, thereby meeting the accuracy standards for RBI maps at a scale of 1:5,000, Class 3 for horizontal accuracy, and a scale of 1:10,000, Class 3 for vertical accuracy. Volume calculations of the stockpile using UAVs yielded a result of 22,750.900 m³, while the truck count method produced a volume of 23,503.300 m³. The volume difference between the two methods was 753.400 m³, with a deviation percentage of 3.2%. Based on the research results, the UAV method is considered capable of providing relatively accurate calculations of coal stockpile volume.

This study aims to analyze the implementation of the Bravo PUPR Online attendance system in improving the work discipline of Civil Servants (ASN) at the National Road Implementation Center of East Nusa Tenggara. The research focuses on punctuality of attendance, consistency in fulfilling working hours, task completion, compliance with attendance procedures, alignment between recorded data and actual conditions, and acceptance of consequences for violations. The study employs a qualitative approach with data collection techniques including observation, documentation, and interviews with leaders, system operators, and ASN as direct users. The results indicate that the implementation of the Bravo PUPR Online attendance system has improved administrative order in attendance and increased ASN awareness of time discipline. However, work discipline has not been fully optimal, as several issues remain, such as inconsistent attendance, suboptimal fulfillment of working hours, and discrepancies between attendance data and actual field conditions. In addition, technical constraints such as internet connectivity and GPS accuracy, as well as behavioral factors like negligence and lack of supervision, also affect system effectiveness. In terms of compliance, the Bravo system integrated with e-HRM is considered effective in detecting violations and enforcing strict consequences, ranging from warnings to administrative sanctions. This demonstrates that the attendance system functions not only as a recording tool but also as an instrument for monitoring discipline.

This study analyzes the regulatory gaps in digital forensics regarding the handling of natural resource crimes and the state’s constitutional responsibilities following the enactment of Law No. 1 of 2024. Modern natural resource crimes, such as illegal logging and illegal mining, have evolved to leverage digital technology, leaving complex electronic traces in the form of GPS data and digital documents. However, Indonesia still faces procedural gaps in the Criminal Procedure Code (KUHAP), unclear technical standards (SNI 27037:2014 is voluntary in nature), and conflicts between the Information and Electronic Transactions Law (UU ITE) and sectoral NRE laws. This normative legal study employs legislative, conceptual, and case-based approaches. The research findings indicate that the absence of digital forensic authentication standards has fatal implications, as evidenced by the Sidoarjo District Court Decision No. 488/Pid.B/2024/PN Sda, which rejected electronic evidence. This situation constitutes state negligence (staatsverzuim) that violates Article 1(3) and Article 33(3) of the 1945 Constitution of the Republic of Indonesia. The study recommends the development of standard digital forensic procedures, the acceleration of ISO/IEC 17025 laboratory accreditation, and the harmonization of sectoral regulations

The development of transportation technology encourages companies to improve vehicle monitoring systems to be more effective and measurable, particularly in addressing speeding violations that can increase accident risks and reduce operational efficiency. This study aims to analyze the implementation and effectiveness of using a buzzer integrated with the Teltonika FMB910 GPS module as a vehicle speed warning indicator at PT. Lacak Cipta Aktual. This research employs a qualitative descriptive method with a case study approach, where data were collected through observation, interviews, and documentation during a one-month industrial internship and analyzed using the Miles and Huberman model, including data reduction, data presentation, and conclusion drawing. The results show that the system is capable of detecting overspeed conditions and automatically activating the buzzer when the vehicle speed exceeds the predefined threshold of 80 km/h. Based on logbook data, the system achieved a success rate of 93.9% in responding to overspeed conditions. The use of a buzzer is proven effective in providing immediate warnings to drivers, thereby improving driver awareness and speed control. However, the system still has limitations, particularly its dependence on GPS signal stability and vehicle electrical conditions. Overall, this study demonstrates that the integration of GPS and a buzzer provides a simple, effective, and cost-efficient solution to enhance driving safety and fleet management efficiency.

The progressive consolidation of navigational instruments into Integrated Bridge Systems (IBS) has fundamentally transformed the sensory and cognitive architecture of modern maritime watch-keeping, creating a paradox of technological sophistication: while IBS enhances navigational efficiency under nominal operating conditions, it simultaneously generates profound human factors vulnerabilities when sensor inputs degrade, fail, or are intentionally disrupted. Despite the safety-critical nature of this vulnerability, empirical human factors research specifically addressing deck officer situational awareness under degraded IBS sensor conditions — particularly in the context of GPS spoofing, radar shadowing, and AIS anomalies — remains insufficiently developed in the maritime research literature. This study investigates the human factors dimensions of IBS situational awareness degradation among deck officers at Sekolah Tinggi Ilmu Pelayaran (STIP) Jakarta, Indonesia, examining how officers perceive, respond to, and recover from degraded sensor scenarios in simulator-based environments. Employing a qualitative research design, data were generated through semi-structured interviews with senior deck officers, navigation simulation instructors, and maritime human factors experts, supplemented by structured observation of IBS simulator degradation scenario sessions. Analysis proceeded through thematic analysis, cross-group comparison, and narrative synthesis. Findings reveal four critical human factors failure patterns under degraded IBS conditions: automation complacency, cross-verification skill atrophy, alert saturation mismanagement, and manual navigation competency erosion — all of which are systematically underprepared for within current STCW-aligned deck officer training curricula. The study proposes a competency-based degraded operations training framework as a principled response to these findings, with direct implications for maritime simulator curriculum design and STCW competency standard revision.

This study aims to describe the implementation of smart government through the Sumbergedang Baru Program in Sumbergedang Village, Pandaan District, Pasuruan Regency. The program is a digital village initiative that utilizes information technology to improve the quality of public services, transparency of governance, and the social and economic empowerment of rural communities. This study employed a descriptive qualitative approach with purposively selected informants, including the village head, village officials, community groups (Pokmas GPS and G4S), and residents as service recipients. The findings show that digital literacy among the community and village officials has begun to develop, as indicated by their ability to use basic devices and applications; however, the utilization of village digital services remains limited and uneven across age groups. In terms of ICT accessibility, the village has established an internet network and public Wi-Fi hotspots, yet network coverage and stability have not fully reached all hamlets. Regarding regulations, the village government has established basic policies through decrees forming community groups and regulating the digital village program, although these have not been comprehensively integrated. In terms of human resource quality, village officials and young cadres are relatively adaptive to technology, but a capacity gap remains among older age groups. Overall, the implementation of smart government through the Sumbergedang Baru Program is still at the stage of building a digital village foundation, requiring further improvements in digital literacy, human resources, infrastructure expansion, and technology-based transparency.

The illicit circulation of narcotics in Indonesia has undergone a fundamental evolution into cyber-enabled crime, where drug syndicates systematically exploit children as technical operators through digital media to sever the main network chain and evade legal detection. This study aims to analyze the anatomy of the modus operandi of narcotics transactions involving children in the digital realm and examine its legal implications for the process of proof and criminal liability. Utilizing an empirical juridical research method with a sociological approach conducted in the jurisdiction of the Metro Police Resort, Lampung, this research identifies a shift in modus operandi towards the "Map System" or Dead Drop Method. In this modus, the child's role is divided into three sophisticated technical stages: pre-transaction via encrypted communication, field execution (mapping & dropping) using precise GPS coordinates, and post-transaction involving digital cleaning, which creates a phenomenon of crime "gamification" where children perceive the criminal act akin to an online game mission. The legal implications of this phenomenon present serious challenges regarding the validity of electronic evidence, which is volatile due to a weak chain of custody, as well as the reconstruction of the child's mens rea, which points towards premeditated intent (dolus premeditatus) driven by high digital literacy rather than mere negligence. These conditions complicate the application of pure diversion as mandated by law; thus, this study recommends a hybrid punishment approach where law enforcement proceeds to break impunity, but sanctions focus on specific rehabilitation in the Special Guidance Institution for Children (LPKA) to reorient the children's digital skills positively.

Attendance is an essential activity in both educational institutions and companies, serving as an indicator of discipline, presence, and individual responsibility. Conventional attendance systems that still rely on manual journals often face several problems, such as vulnerability to manipulation, data loss, and physical damage. Meanwhile, modern methods such as fingerprint, QR code, RFID, and GPS are not entirely ideal since each has its own limitations in terms of cost, accuracy, user convenience, and potential misuse. For instance, fingerprint systems raise hygiene concerns due to shared use, while QR code and GPS methods are prone to fraud and location spoofing. To address these challenges, this study proposes a face-based attendance simulation system by integrating the YOLOv8 algorithm for face detection and Local Binary Pattern Histogram (LBPH) for face recognition. YOLOv8 was chosen for its ability to detect faces in real time with high speed and accuracy, while LBPH is employed for face recognition due to its robustness in handling variations in facial features and its relatively low computational requirements. This makes the system efficient even when implemented on medium-specification devices. The system was tested on 25 participants with a total of 250 attendance attempts. Based on the confusion matrix analysis, the system achieved outstanding performance with 98.4% accuracy, 98.4% precision, 100% recall, and a 99.2% F1-score. Furthermore, the system automatically recorded attendance dates and times with an average latency of 69.185 ms, proving its capability to operate quickly and reliably in real-world scenarios. Nevertheless, several limitations were observed, such as decreased accuracy when the face moved too quickly during image capture, as well as potential performance degradation under extreme lighting conditions. Despite these challenges, the proposed system demonstrates excellent performance and offers a promising solution for efficient, hygienic, and fraud-resistant attendance management applicable to both educational and professional environments.
