The protection of children's data on social media is an issue that requires serious attention from various parties in order to prevent various negative impacts on users, especially children. This research uses a normative legal research method. The results of the study indicate that forms of misuse of children's data on digital platforms, such as excessive data collection, data mining and profiling, sale of data to third parties, targeted advertising, and identity theft, demonstrate that children's digital activities can pose serious threats to their privacy rights and security. Legal regulations and prevention of misuse of children's data have been regulated under Law Number 27 of 2022 concerning Personal Data Protection. However, the regulation still has several weaknesses, such as the absence of detailed provisions regarding the special processing of children's data. Effective legal policies to protect children's personal data require specific regulations or implementing rules that comprehensively regulate the collection, use, and storage of children's personal data. The processing of children's personal data must also involve verified consent from parents or legal guardians, along with active government supervision to prevent data misuse. In addition, every digital platform is required to implement strong cybersecurity standards to protect children's personal data from data breaches and illegal access.

This study is motivated by the existence of dual mechanisms of accountability for members of the Indonesian National Police (Polri) who commit narcotics-related crimes, namely criminal proceedings in the general courts and ethical-administrative proceedings through the Police Professional Code of Ethics Commission (KKEPP). This dual system often raises debates regarding the legitimacy of ethical sanctions, the application of the ne bis in idem principle, and the consistency of law and ethics enforcement within the Indonesian legal system. The purpose of this research is to analyze the legal accountability system for Polri members who commit narcotics crimes in both the criminal and ethical domains, as well as to examine the principles of professional ethics in relation to criminal court decisions and KKEPP decisions. This research applies the legal system theory and professional ethics theory. The method used is normative legal research with statutory, conceptual, and case approaches. The results show that the Indonesian legal system recognizes criminal and ethical accountability as two distinct but complementary mechanisms. Criminal court decisions determine the legal guilt of the offender, while KKEPP decisions assess integrity, moral responsibility, and the professional suitability of Polri members. Ethical sanctions in the form of Dishonorable Discharge (PTDH) do not violate the ne bis in idem principle because they fall within the domain of administrative law and professional ethics. The relationship between criminal and ethical decisions is complementary and plays an important role in maintaining professional integrity, institutional professionalism, and public trust in Polri

Lung diseases are a serious health issue that requires prompt and accurate treatment. However, in practice, medical professionals often face challenges such as high patient volumes, limited examination time, and the similarity of symptoms across different types of lung diseases, which make it difficult to consistently establish an initial diagnosis. This study aims to design and develop a medical decision support system to diagnose lung diseases using an Artificial Neural Network (ANN) with the Hebb Rule algorithm. The types of diseases focused on in this study include Asthma, Bronchitis, COPD, and Pulmonary TB. The research methodology utilized 100 patient medical records from H. OK Arya Zulkarnain General Hospital as training data, consisting of 39 clinical symptom variables. The system was developed using the PHP programming language and a MySQL database. The Hebb Rule algorithm was applied to perform network weight learning so that the system could recognize patterns of relationships between symptoms and disease types based on historical data. The results of the study show that the Hebb Rule algorithm was successfully implemented into a web-based system capable of generating diagnostic decisions based on the highest activation values in the output neurons. This system can process patient symptom data quickly and provide prediction results consistent with the training data patterns. This study concludes that the use of ANNs with the Hebb Rule method is effective as a tool for early detection and decision support for medical personnel to improve the efficiency of healthcare services in hospitals.

This study aims to propose and test a model of the influence of machine learning techniques in entrepreneurship education on improving the business innovation readiness of vocational high school graduates, which has implications for students' entrepreneurial interest and innovative abilities in the digital era. We distributed an online questionnaire to 450 respondents from vocational high school students majoring in business and management in Indonesia. Data analysis used a structural equation modeling (SEM) approach with AMOS 26 software, through the stages of measurement model and structural model for hypothesis testing.The results of this study indicate that three main factors shaping machine learning techniques in entrepreneurship education (e.g., predictive analytics, recommendation systems, and clustering for business ideas) can influence students' business innovation readiness. Of these three dimensions, only predictive analytics significantly increases entrepreneurial interest and innovation readiness. Meanwhile, recommendation systems and clustering show negative or insignificant results on entrepreneurial interest directly, although they contribute to improving technical competency. Machine learning-based entrepreneurship education in vocational schools focuses not only on teaching business theory but also requires developing predictive and data analysis skills that determine graduates' business innovation readiness. These findings emphasize the importance of integrating machine learning into vocational curricula to prepare vocational school students to face the challenges of entrepreneurship in the Industry 4.0 and 5.0 eras.

The development of digital technology has brought significant changes to the world of education, particularly in the development of technology-based learning media. Students, as the digital generation, are required to have adequate digital literacy skills to effectively utilize technology in the learning process. One learning medium that can support digital literacy is K-Visoft Flipbook Maker, software that can convert digital documents into interactive e-books. This Community Service (PKM) activity aims to improve the digital literacy skills of FKIP Asahan University students through training on the use of K-Visoft Flipbook Maker. The methods used included preparation, training implementation, mentoring, and evaluation. Forty FKIP Asahan University students participated in the activity. The results showed an increase in students' abilities in developing digital learning media. The average pretest score of 62.4 increased to 86.7 in the posttest. This 24.3-point increase demonstrates the effectiveness of the training in improving students' digital literacy skills. Furthermore, students were able to produce interactive flipbooks that can be used as learning media. Thus, the K-Visoft Flipbook Maker training was effective in improving students' digital literacy skills.

This community service program aimed to accelerate the digitalisation of learning at SDN Lebakwangi through strengthening human resource capacity and information and communication technology (ICT) infrastructure. Before program implementation, a needs assessment was conducted involving 18 teachers to identify the school's initial conditions. The findings revealed a relatively high level of digital device ownership, with 16 teachers owning smartphones and 13 owning laptops. However, the integration of ICT into teaching and learning remained limited; 72.2% of teachers reported using technology only occasionally due to internet quota constraints. Approximately 72% of respondents relied on personal mobile data with network quality insufficient for video-based learning, while only 27% had access to the school’s Wi-Fi network. Teachers’ digital literacy competencies varied, with most falling within the moderate to high categories, although several teachers still demonstrated very low levels of digital competence. These findings served as the basis for implementing a differentiated training strategy. The analysis also indicated that technology use was predominantly focused on presentation tools such as Canva, PowerPoint, and YouTube (77%), whereas the utilization of interactive platforms, including learning management systems (LMS) and digital assessment applications, remained low (16%). Furthermore, 88.8% of teachers expressed a preference for hands-on training. Based on these findings, the community service team designed a program tailored to the partner school's needs to support sustainable digital transformation in learning.

Abstract: This study was conducted to determine how well students understand the Decision Support Systems course using the MABAC method. This study involved five Royal University students as the main subjects. During the learning process, it is often difficult to assess students' comprehensive understanding from only one aspect, so a method that can consider various factors simultaneously is needed. The five students were evaluated using four criteria — Material Understanding (25%), Application & Discussion Participation (30%), Activeness & Technical Skills (30%), and Communication (15%). The targeted output is a scientific article that can serve as a reference for Royal University, in designing a more systematic and objective data-based evaluation system. In this study, previously the assessment was based on several things such as activeness in class, assignment results, exam scores, and participation during lectures. The MABAC method was used because it can help in making decisions based on multiple criteria more objectively. The collected data was then processed to produce a ranking that indicates the level of understanding of each student. The results of the study indicate that the MABAC method can help provide a clearer and more structured picture of student understanding. With this method, lecturers can more easily identify which students have grasped the material well and which still need further guidance. This research is expected to become an alternative way to improve the quality of learning evaluation at Royal University.   Keywords: MABAC; comprehensive understanding evaluation; decision support system; learning outcomes; multi-criteria decision making   Abstrak: Penelitian ini dilakukan untuk melihat seberapa baik mahasiswa memahami mata kuliah Sistem Pendukung Keputusan dengan menggunakan metode MABAC.

Abstract: This study aims to explore the pedagogical values within the Pilandok Takial Kial dance as an instrument for revitalizing youth ethics in Labuhanbatu Regency. In the digital era, teenagers face challenges of moral degradation and identity crisis that distance them from their local cultural roots. This study employs a qualitative approach with descriptive-analytical methods using Roland Barthes' Semiotic theory. Data were collected through textual observation of movements, literature studies, and in-depth interviews with dance maestros and traditional leaders. The results show that the Pilandok dance is not merely an aesthetic representation of a mousedeer’s movements but a system of signs containing strategic moral messages. Symbols of vigilance (eyes), resilience (takial-kial feet), and manners (worship gestures) are manifestations of the "civilized ingenuity" concept. The implications of this study emphasize the importance of integrating dance philosophy into character education curricula to shape a Generation Z that is intellectually bright yet still upholds Malay values of politeness. Keywords: Pilandok Takial Kial Dance, Semiotics, Youth Ethics, Labuhanbatu, Cultural Revitalization.   Abstrak: Penelitian ini bertujuan untuk mengeksplorasi nilai-nilai pedagogis dalam Tari Pilandok Takial Kial sebagai instrumen revitalisasi etika remaja di Kabupaten Labuhanbatu.

Abstract: The results of the study are: Multiple linear regression analysis produces the equation Y = 1154.050 – 0.100 ROA + 0.078 LDR + 0.521 NIM + e. Thus, ROA (X1), LDR (X2), and NIM (X3) have a positive relationship with profit growth and decrease profit growth. The partial test (t-test) states that ROA (X1) has no effect on profit growth with a significant value of 0.357 > 0.05. And the calculated t-value (-0.928) > -ttable (-1.67065) so that H0 is accepted and H1 is rejected. LDR (X2) does not significantly affect profit growth by 0.247 > 0.05. With a calculated t value of 1.169 < ttable 1.67065 so that H0 is accepted H1 is rejected. and NIM (X3) significantly affects profit growth by 0.004 < 0.05. With a calculated t value of 3.013 > ttable 1.67065 so that H1 is accepted H0 is rejected. Simultaneous test (F-test) states that ROA. LDR. and NIM simultaneously affect profit growth with a significant value of 0.002 < 0.05 and Fcount < Ftable which is 5.547 > 2.76. So H2 is accepted and H1 is rejected. The R2-test produces an adjusted R square value of 0.180. meaning  the correlation of independent variables ROA, LDR, and NIM contribute 18.0% to profit growth, while the remaining 82% is influenced by other factors not included in this research model. This means that ROA, LDR, and NIM have a negative impact on profit growth, with coefficients of <50%.
