Abstract

An underground tank is a type of tank installed by burying it on the ground. Underground tanks in the form of a storage area with large dimensions for either liquid or gas, especially BBM (fuel) which is stored underground at Public Fuel Filling Stations his (SPBU). The supply of liquid in this tank really needs to be maintained to meet the need for liquid. In order to be able to monitor the volume of liquid in the underground tank, a device was designed that can monitor the volume of liquid in the tank remotely. This device uses an ultrasonic sensor that can detect the volume of liquid that has been converted from the distance detected by the sensor, and uses Wemos D1 mini on the device and ESP32 on the server as a microcontroller that sends data from the reading process to smartphones and websites. The device works on ultrasonic sensor which can sense the distance and with some calculation it detects how much liquid is sensed as a volume and employs a Wemos D1 mini on the side of device and an ESP32 on the server part as a microcontroller that sends reading data to smartphones and websites. The smartphone displays show liquid volume and distance shown by the sensor while in the server display distance is plotted against time in graphical form. Test results reveal that this device can remotely detect underground tank liquid volume using smartphones or websites with a success rate of 72.35%. This failure rate of 27.65% is caused by curved tanksurface and misplacement of the tank.

Abstract

The efficiency of vehicle exhaust systems is critical for reducing backpressure and emissions, enhancing performance and sustainability of harvesting energy. This study investigates the effect of an additional body modification at the exhaust tip on pressure and velocity distributions using Computational Fluid Dynamics (CFD) simulations in SolidWorks. Simulations were conducted at inlet velocities of 10, 15, and 20 m/s. Results show that the modified design does not increase backpressure, with the maximum observed change being a minor reduction of 0.137% at 20 m/s. These findings confirm that the additional body can be safely integrated without adversely affecting engine performance, while also improving downstream flow uniformity. This supports its viability for use in energy harvesting systems and highlights its relevance for sustainable exhaust system development.

Abstract

The phenomenon of child sexual exploitation shows an alarming trend. Although the number of cases is not always high quantitatively, the impact on victims is extremely serious and multidimensional affecting physical, psychological, social aspects, and the child’s future. Reported cases often involve girls under the age of 18 who fall victim to people close to them, such as familiar adults, neighbors, or even family members. In several instances, victims are drawn into covert prostitution networks, either directly or through social media, where they are lured with promises of money, jobs, or even love, only to end up being trafficked and sexually exploited. The aim of this research is to analyze Legal Protection for Children Victims of Sexual Exploitation in the Jurisdiction of Siak Police, to examine the obstacles in providing such protection, and to explore solutions to overcome these challenges. This study uses a sociological legal research method. Based on the findings, it is revealed that while legal protection for children victims of sexual exploitation in the jurisdiction of Siak Police is already in place, its implementation is not yet optimal, due to various challenges both in law enforcement and victim support services. This is evident from the continued occurrence of child sexual exploitation cases, both those that have been handled and those that remain undisclosed. This situation shows that, although legal instruments and related institutions exist, their implementation at the practical level is not yet fully effective in providing maximum protection to children as the most vulnerable group. One key indicator of the inadequacy of legal protection is the recurring cases of child sexual exploitation. These cases occur not only in private environments such as homes or schools but also in public spaces, which should be safe for children.

Abstract

The purpose of this study is to analyze the implementation of the monitoring and investigation results by the Inspectorate Auditor of Rokan Hilir Regency on regional-owned assets, to analyze the obstacles in the implementation, and to analyze the efforts made to overcome those obstacles. The method used is sociological legal research. Based on the research findings, it is known that the implementation of the monitoring and investigation results by the Inspectorate Auditor of Rokan Hilir Regency on regional-owned assets has not been running optimally. This is evident from the discrepancies between audit findings and the corrective actions taken by the relevant Regional Government Organizations (OPD). Although some corrective measures have been initiated—such as updating inventory data, re-labeling items, and organizing asset documentation—these efforts are not yet evenly implemented across all OPDs and are not fully in accordance with the provisions of asset management as regulated in the Regulation of the Minister of Home Affairs Number 47 of 2021 concerning Procedures for Bookkeeping, Inventory, and Reporting of Regional-Owned Assets. The obstacles in implementing the monitoring and investigation results include, first, from an administrative perspective, the presence of numerous assets without adequate supporting documents such as certificates, handover reports, or decisions determining the status of use. These assets frequently become recurring findings due to the lack of legal and physical verification. Second, from a technical perspective, some OPDs do not have dedicated personnel managing assets, resulting in the responsibility being handed to other staff members who lack relevant expertise. Third, challenges also arise from asset control by third parties. Efforts to overcome these obstacles include, first, reorganizing the asset documentation system and strengthening internal supervision.
