The corruption case in the BTS 4G project by the Ministry of Communication and Information Technology (Kominfo), which involved the misuse of funds in the construction of BTS towers in Indonesia's 3T (underdeveloped, frontier, and outermost) regions, has become a major public concern in recent years. The Rp 9.8 trillion project is suspected to have been misappropriated by several officials involved. This study aims to examine the role of social media in increasing public participation in the monitoring and mitigation of the corruption case. The research method used is a descriptive qualitative approach combined with social media analysis. The findings show that social media plays a significant role in accelerating the dissemination of information related to the BTS 4G corruption case, raising public awareness, and exerting social pressure on law enforcement agencies to take action. Furthermore, social media also facilitates digital activism, which mobilizes public support and strengthens oversight of government policies. This study concludes that social media serves as an effective tool for social control, although it also faces challenges in terms of the spread of hoaxes and disinformation.
 

Coal companies in Indonesia each year experience an increase in the amount of production that will be distributed to industries both domestically and abroad. Where some coal companies entrust other companies as contractors in terms of renting heavy equipment units to move overburden or all soil/rock that covers the coal layer. In terms of renting heavy equipment units, the contractor company will calculate the rental cost of the heavy equipment unit when carrying out mining activities by calculating the number of iterations on the heavy equipment unit used. This iteration is the number of heavy equipment work cycles in a certain time unit, sometimes the calculation of the number of iterations has a difference in calculation which results in one party experiencing a loss. Therefore, to overcome the difference in calculation, the researcher created a tool, namely the "Prototype of the Automatic IOT-Based Iteration Calculation Tool on Heavy Equipment Units" so that there is no more difference in the calculation of iterations during the mining process and the productivity of the tool will be in accordance with the planned plan.

This study aims to analyze the Implementation of the Policy of the Directorate General of Islamic Education Circular No. 10 of 2024 concerning the Free Nutritious Meal Program (MBG) at the Tarogong Islamic Boarding School, Garut Regency, and its impact on students' learning motivation. Education, especially in Islamic boarding schools, requires special attention regarding adequate nutritional access for students, which has a significant impact on the learning process. The research method used is a qualitative approach with a case study design, which allows researchers to explore in depth the experiences and perceptions of students, teachers, Islamic boarding school leaders, kitchen managers and parents regarding this program. The results of the study indicate that this policy has a positive impact on students' learning motivation, where the majority of students reported increased enthusiasm and concentration in participating in learning after receiving nutritious food intake regularly. However, there are challenges in its implementation, such as the quality of distribution and the need for training for supporting staff. This study provides recommendations for related parties to improve collaboration between educational institutions, local governments, and logistics providers for the sustainability of the program, as well as implementing evaluation mechanisms to improve aspects that are less effective. In conclusion, the Free Nutritious Meal Program (MBG) not only functions as a nutritional intervention, but also as an important strategy in improving the motivation and learning achievement of students in Islamic boarding schools.

This study examines the ways in which digitalization has contributed to the increased competitiveness of MSMEs in Medan City, in light of legislative measures imposed by the Medan City Government. Based on the facts that micro, small, and medium-sized enterprises (MSMEs) have been forced to undertake digital changes due to the pandemic, this study examines the importance in digitalization as a strategy for MSMEs in this era of the digital economy. Small, medium, and micro-sized enterprises (MSMEs) in Medan City may benefit from the city government's digitization initiatives, which is why this study seeks to investigate them. The method used is the Systematic Literature Review (SLR), which involves looking at academic articles and secondary materials about the digitalization of MSMEs in Medan City. The research found that digitization has various benefits for MSMEs, such as increasing their competitiveness, streamlining their operations, and accessing new markets. Mentorship applications, training, and the incorporation of micro, small, and medium companies (MSMEs) in online platforms or local e-Catalogs are examples of digitalization-supportive policies implemented by the Medan City Government that have been essential in achieving success. The results of this research highlight the importance of partnerships between government departments, MSMEs, and other stakeholders in improving MSMEs' digital skills so that they can compete globally.

Traffic congestion is a common issue in developing metropolitan areas, impacting both economically and socially. Long vehicle queues result in delays for many vehicles, which increases travel time and contributes to deteriorating air quality due to emissions from motor vehicles at intersections. One of the influencing factors is the non-optimization of intersections due to delays. Previous studies commonly use the Highway Capacity Manual Indonesia, 2023, to analyze intersection optimization. However, this study will utilize PTV Vissim software. In planning the intersection, some factors must be considered, such as capacity, density, speed, and type. An average daily traffic survey and a road geometric survey will be conducted in the field survey. The analysis will be performed using PTV Vissim software to optimize the 3 (Three) Talang Buluh intersection in Banyuasin Regency by examining the impact of vehicle queue length and evaluating policies for improving traffic management. According to the analysis results, the data from the First Scenario shows that the maximum vehicle queue length reaches 124.02 meters, with an average delay of 18.75 seconds from the Palembang direction. In the second scenario, installing traffic signal control devices increased the queue length to 287.95 meters from the Betung direction, with the most extended delay reaching 129.52 seconds. The third scenario, which involved geometric changes at the intersection, successfully reduced the vehicle queue length to just 47.70 meters from the Palembang City direction. Additionally, the most extended delay recorded was only 11.59 seconds, demonstrating the effectiveness of this approach, though it is costly and unsuitable for short-term use. Overall, Scenario 1 can serve as a short-term solution for intersection optimization. However, if road widening improvements are feasible, Scenario 3 is the optimal solution for enhancing traffic efficiency and effectiveness, significantly reducing vehicle queues and delays. This is crucial for implementing long-term traffic management strategies at the Talang Buluh Intersection in Banyuasin Regency.

Increased global mobility has made foreigner surveillance a strategic issue in Indonesia's immigration policy. This research aims to analyze how the principles of Collaborative Governance are applied in the supervision of foreigners by the Directorate General of Immigration, as well as identify the actors involved and the forms of collaboration that occur. Using a descriptive qualitative approach through documentation studies and literature review, this study found that collaborative governance has been implemented in various forms such as joint operations, data exchange, and community engagement. The collaboration involves both state (DG Immigration, Police, BIN, Ministry of Foreign Affairs) and non-state actors (media, NGOs, communities). Despite its effectiveness, collaboration still faces obstacles such as sectoral ego and the absence of a strong regulatory framework. The results of this study indicate the importance of institutional strengthening and cross-sectoral integration systems to encourage adaptive and sustainable immigration control.
