This study discusses the Decision of the Business Competition Supervisory Commission (KPPU) Number 16/KPPU-M/2023 regarding the delay in notification of the takeover of PT Kadi Indonesia Manufaktur shares by Nippo Corporation. The acquisition transaction was legally effective on June 3, 2021, but was only notified to the KPPU on October 18, 2021, which exceeded the 60-day working limit according to KPPU Regulation Number 3 of 2020. The purpose of this study is to analyze the legal principles used by the KPPU and assess the application of Article 29 of Law Number 5 of 1999 in conjunction with Article 5 of Government Regulation Number 57 of 2010. The method used is normative juridical with a case study approach. The results of the study show that the KPPU applies the repressive principle, namely that legal action is taken after the violation occurs. Although no bad intentions were found on the part of Nippo Corporation, elements of violation were considered proven, including asset values ​​exceeding the threshold and negligence in fulfilling administrative obligations. As a result, KPPU imposed an administrative sanction in the form of a fine of Rp1 billion. This finding emphasizes the importance of business actors' compliance with the provisions of acquisition notifications and shows the need to strengthen socialization and preventive warnings to prevent similar violations in the future.

The integration of social media into digital education has transformed how communities engage in collaborative learning. While social media platforms were initially designed for communication, they have evolved into micro-ecosystems that support community-based e-learning. This study conducts a Systematic Literature Review (SLR) to examine the role of social media as a micro-ecosystem in enhancing collaborative learning environments. Using the PRISMA protocol, 450 articles were initially identified from Scopus, Web of Science, IEEE Xplore, and Google Scholar. After multiple screening stages, 80 articles met the inclusion criteria and were analyzed in-depth. The findings indicate that platforms such as WhatsApp, Facebook, YouTube, and Edmodo significantly enhance learning engagement, collaboration, and knowledge sharing. Specifically, student engagement increased by up to 40% compared to traditional LMS-based methods, with satisfaction rates exceeding 80% among Edmodo users. Moreover, WhatsApp communities achieved a message open rate of 98%, demonstrating high responsiveness and interaction quality. However, challenges such as low digital literacy, data privacy concerns, and distractions from non-academic content were also identified. This research contributes a comprehensive synthesis of how social media can function as a micro-ecosystem to foster inclusive, flexible, and community-driven learning. It also offers strategic recommendations for educators and policymakers to optimize the use of social platforms for education in the digital era.

This study aims to analyze the community’s interest in the digitalization design to support the agricultural potential of Sukaharja Village, Bogor Regency. The village has significant agricultural potential but faces marketing challenges due to limited access to broader markets and dependence on middlemen. The research employed qualitative methods through in-depth interviews and questionnaires distributed to 30 farmers managing commodities such as taro, pineapple, and ornamental plants. The findings indicate that while farmers show high enthusiasm for digital solutions like e-commerce, their digital literacy and technological access remain limited. To address these issues, the team developed a digital platform named “Suka Belanja di Harja,” designed to improve product marketing, provide educational content, and empower local farmers. The initiative had a positive impact by increasing farmers’ motivation and awareness about digital marketing. However, ongoing support, infrastructure improvement, and tailored training are necessary to ensure successful digital transformation in rural agriculture.

Community Service Activities are a real form of students' social concern for the surrounding environment. Five students of the Management Study Program at Borneo Tarakan University carried out community service in collaboration with local MSME actors through an activity entitled "Sharing Chocolate Bread as a Form of Social Concern".

This study develops an image processing application to automatically detect the ripeness level of tomatoes using the YCbCr color space transformation. This method is effective because it is able to separate the luminance and chrominance components, so it can identify color changes that indicate the ripeness level of tomatoes, namely unripe, semi-ripe, and ripe tomatoes. The application is designed with matlab and uses a GUI interface that makes it easy for users to upload and process images. Based on trials on image samples, the system is able to classify tomato ripeness with 100% accuracy on a limited test dataset. The classification process is based on three main parameters: the red area ratio, the average value of the Cr channel, and the average value of the Cb channel. The results of the study indicate that this approach can be used as a digital solution in the automatic and efficient tomato sorting process
