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.

By applying the Waterfall approach as a software development methodology, this research goes through several important stages, namely needs analysis, system architecture design, coding, quality testing, and maintenance. Key features developed in the E-Presence system include attendance validation based on GPS location to ensure the authenticity of the user's position, real-time attendance data recording that is stored directly to the database, and automated reporting that simplifies the administration and attendance evaluation process of trainees. The use of this technology is expected to increase the effectiveness, efficiency, accountability, and transparency in the management of attendance data, while supporting the implementation of modern information systems in regional job training institutions. The results of the implementation show that the E-Attendance system is able to provide several significant benefits, including increasing the accuracy of attendance data, reducing the potential for fraud, accelerating the recapitulation process, and supporting decision-making in training activities. In addition, this system also provides added value in the form of increased trust in attendance administration management because the transparency of the data produced can be monitored directly. Thus, the design of a website-based E-Presence information system with geolocation integration at BLK Situbondo has proven to be effective in overcoming the problem of manual attendance, while contributing to improving service quality, technological innovation, job training governance, and strengthening digital transformation in the education and training sector.

This study aims to improve the performance of roadside supervision services for Baggage Towing Tractor (BTT) movements at Kualanamu International Airport, Deli Serdang. The research background is based on the high level of operational risk on the airside, which requires strict supervision of Ground Support Equipment (GSE) vehicles. The method used is descriptive qualitative with data collection techniques in the form of direct observation, semi-structured interviews, and field documentation. The results of the study indicate that violations of Standard Operating Procedures (SOP) such as excessive speeding, inappropriate lane use, and compliance with procedures are still common. The main causes include lack of training, weak monitoring systems, and low awareness of safety culture. From the results of the observation, it was found that supervision is still manual and not optimally supported by monitoring technology such as CCTV with a real-time integration system. In addition, the number of supervisory personnel is also not able to cover the entire service area of the road which is quite extensive, especially during peak operating hours. The lack of a firm reward and punishment system also contributes to the low discipline of BTT drivers. Interviews with several BTT operators showed that they have not received regular safety training, and most do not understand the importance of complying with established signs or markings. Therefore, it is recommended that airport authorities implement a monitoring system through the use of sensor-based technology and GPS tracking, as well as increase the intensity of occupational safety training. Furthermore, a dedicated unit should be established to continuously monitor GSE movements and integrate a digital reporting system to ensure prompt action on violations. Improving safety culture can also be achieved through internal campaigns and ongoing outreach.

This research is expected to provide sustainable energy solutions for the people of Toili Barat District and support the development of the tourism sector.

This study aims to design and develop a pipeline leakage detection system based on the Internet of Things (IoT) that provides real-time notifications and determines the location of leaks with high accuracy. Pipeline leakage is a serious issue, as it can lead to water wastage, environmental damage, and high maintenance costs. Therefore, a system that can detect leaks quickly and accurately is crucial for improving the efficiency of pipeline infrastructure management. The system developed in this study uses an ESP32 microcontroller, Waterflow sensor, and GPS module. The ESP32 microcontroller serves as the central processing unit that processes the data received from the Waterflow sensor and the GPS module. The Waterflow sensor detects changes in water flow that indicate a leak in the pipeline. When an abnormal reduction in flow is detected, the sensor sends a signal to the microcontroller. The GPS module then provides location coordinates, pinpointing the exact location of the leak, allowing the maintenance team to quickly address the issue. Additionally, the system is integrated with the Blynk application, which enables remote monitoring through a mobile device. The Blynk application provides a user interface that facilitates the monitoring of pipeline status and delivers notifications whenever a leak is detected. Testing results show that the IoT-based leakage detection system is capable of identifying leaks and sending real-time information with good accuracy. With this system, the process of identifying and addressing pipeline leaks can be done faster and more efficiently, ultimately reducing the losses caused by leakage. The system also offers a more effective solution for pipeline maintenance, improving the reliability of water distribution systems and reducing water resource wastage.

Stockpiles are accumulations of materials such as coal or ore stored at specific locations. Accurate stockpile volume measurement is crucial in the mining and logistics industries for inventory management and cost efficiency. Conventional methods like Real-Time Kinematic (RTK) GPS rely on surface coordinate measurements but require numerous points, especially for irregular-shaped objects. Newer technologies like Terrestrial Laser Scanners (TLS) offer high-precision alternatives by capturing thousands of points per second, expediting and enhancing the resolution of volume measurements. This study compares TLS and RTK GPS methods in measuring the volume of andesite rock stockpiles at PT Bara Tabang. This research uses a quantitative approach, involving six Ground Control Points (GCPs) measured using the Sokkia GRX2 RTK GPS on October 24, 2024. TLS generated over 8.6 million point cloud data filtered down to 35,197 points, while RTK GPS yielded 2,276 coordinates. Accuracy testing showed very small RMSE values (RMSEr: 0.008 m; RMSEz: 0.007 m), and both LE90 and CE90 demonstrated 90% confidence within a 0.012 m range. Volume calculation using Surpac software with the cut and fill method showed TLS produced a volume of 18,766 bcm (51,982 tons/m³), while RTK GPS resulted in 18,694 bcm (51,782 tons/m³), with a difference of 72 bcm or 0.211%.These results indicate that both methods offer acceptable accuracy; however, TLS provides greater data density, efficiency, and precision, particularly for complex or large-scale stockpile objects. Therefore, TLS is recommended for high-accuracy volume measurement in mining operations that require efficiency and detailed analysis.
