In the era of globalization, university graduates are required to have the ability to implement knowledge in real practice, which is realized through the Field Work program. This study aims to evaluate the compliance of Task Force reporting at PT PLN (Persero) North Sumatra Main Distribution Unit (UID North Sumatra). The method used is a quantitative approach with K-Means Clustering. Compliance reporting data was obtained from internal company documents, which then went through the preprocessing and clustering stages using the K-Means algorithm, with the determination of the optimal cluster number through the Elbow and Silhouette methods. The K-Means clustering analysis results identified two groups of units with different levels of compliance. Cluster 2, consisting of UP3 Binjai and UP3 Sibolga, showed a higher and more consistent level of reporting compliance. In contrast, Cluster 1 (including UP2D, UP3 B. Barisan, UP3 L. Pakam, UP3 Medan, UP3 Medan Utara, UP3 Nias, UP3 P. Sidimpuan, UP3 P. Siantar, and UP3 Prapat) had a tendency for lower compliance. This finding indicates a difference in reporting consistency that affects the effectiveness of work safety supervision. The K-Means method is proven to help PLN management identify units with low compliance, allowing corrective actions to be prioritized appropriately.

Information system security faces serious challenges due to increasingly complex cyber attacks. Intrusion Detection Systems (IDS) require efficient approaches to handle high-dimensional data such as the NSL-KDD dataset with 41 features. This study aims to implement the Genetic Algorithm (GA) for feature selection on the NSL-KDD dataset to improve the efficiency and accuracy of network attack detection. The method used is computational experimental research, involving data preprocessing, GA implementation for feature selection, building a classification model using Random Forest, and performance evaluation based on accuracy, precision, recall, F1-score, and computation time. The results show that GA successfully reduced features from 41 to 12 features (70.7% reduction), significantly improving computational efficiency. However, model accuracy slightly decreased from 0.4973 to 0.4951, indicating that while GA is effective for feature selection, the elimination of certain features may reduce classification capability. The implication of this study is that GA can be used as a tool to simplify intrusion detection models, but it should be combined with parameter optimization and data imbalance handling to achieve more optimal performance.  

This study aims to analyze the influence of internal control systems and transparency on the accountability of village financial management. This type of research is quantitative and descriptive, using primary and secondary data. Data were collected using questionnaires and literature studies. The population was the Tanjung Datuk community and village officials, Siak Kecil sub-district, Bengkalis district, Riau. The sampling technique used was accidental sampling, with Yamane sample measurements, so the number of samples obtained was 237 people. The data analysis technique used multiple linear regressions with validity, reliability, classical assumptions and hypothesis testing using SPSS software. The results of this study indicate that the internal control system has a positive effect on the accountability of village financial management. However, transparency does not affect the accountability of village financial management. This study provides theoretical implications, especially in completing the theory regarding the influence of the internal control system on accountability and support for the theory of stewardship and legitimacy. This study can then be a reference for the village government in maintaining and improving the accountability of village financial management in implementing the internal control system.

This study explores the comparison of higher education financing models between Indonesia and several Middle Eastern countries, aiming to understand their impact on educational success. The research employs a qualitative approach, analyzing government budgets, funding mechanisms, and educational outcomes documented in recent reports. Findings indicate significant differences in financing structures, with Middle Eastern countries often allocating higher per-student funding and implementing more diverse financial support systems such as scholarships and public-private partnerships. In contrast, Indonesia faces challenges in equitable fund distribution despite increasing budget allocations. The study reveals that effective financing positively correlates with improved educational infrastructure, faculty quality, and student performance. The implications highlight the need for Indonesia to enhance funding strategies by adopting best practices observed in the Middle East to achieve sustainable educational development and greater academic achievement.

This community service activity was conducted in a Christian ministry institution located in Makassar City, South Sulawesi. The Student Creativity Program (PKM) was motivated by the reality that many people in Makassar have not yet known or believed in Isa Al-Masih (Jesus Christ )as Lord and Savior. As a city with a predominantly non-Christian population, evangelism in Makassar needs to be carried out contextually, wisely, and lovingly, without offending the beliefs of the surrounding community. The “PI 3 Saja” method (an acronym for Evangelism anytime, anywhere, and to anyone) serves as a relevant and effective strategy for reaching out to society. Through the 5P approach (Pertalian—Relationship, Peralihan—Transition, Penginsafan—Conviction, Pengabaran—Proclamation, and Penyelesaian—Commitment), this method emphasizes the importance of friendship, empathy, and naturally sharing the Gospel in everyday conversations. The purpose of this activity was to train participants in the institution to become contextual evangelists who can share the Good News without coercion, but rather through exemplary living and genuine friendship with others. The training and field practice results showed positive responses from the community, the formation of small discipleship groups (house churches), and an increased sense of courage and sensitivity among participants in sharing the Gospel in non-Christian environments. This activity demonstrates that evangelism can remain relevant and effective when it prioritizes love, relationships, and sensitivity to local culture.

The Indonesian Naval Academy (AAL) as a military educational institution requires a large electricity supply to support its operational activities, including in the Sapudi Building of the Engineering Department. This study aims to design a solar energy system to supply the electricity needs for lighting in the building. The method used is Research and Development (R&D) with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). Data collection was conducted through direct observation of building conditions, electrical equipment, and solar radiation intensity data in Surabaya. The research results show that the total electricity requirement for lighting in the Sapudi Building is 4.686 kW with a total of 143 lights (96 neon lights and 47 light bulbs). Based on calculations with an average solar radiation of 5.00 kWh/m²/day, the designed system requires 41 units of Solar PV Lesso HPM 550W panel type with 21.3% efficiency and 9 units of Panasonic LC-P12100NA batteries with a capacity of 100Ah arranged in 3 series and 3 parallel configurations. This study proves that the utilization of solar energy can be an efficient and sustainable alternative solution to reduce dependence on conventional electricity in the AAL environment, while supporting the implementation of renewable energy in Indonesian military institutions.

This study aims to analyze the effect of liquidity and solvency ratios on the profitability of PT GoTo Go-Jek Tokopedia Tbk. The liquidity ratio in this study is measured using the Current Ratio (CR), while the solvency ratio uses the Debt to Equity Ratio (DER) and Debt to Asset Ratio (DAR). The research data includes the 2018–2020 financial statements of PT Tokopedia Tbk and the years 2021–2023 after the company transformed into PT GoTo Go-Jek Tokopedia Tbk. The research method uses a descriptive quantitative approach with secondary data from the company's annual financial statements. The results show that the company's liquidity ratio fluctuates in the range of 1.55–3.14, while the DER is in the range of 0.12–0.42 and the DAR is between 0.17–0.34. The results of the simultaneous test showed the value of sig. The F Change of 0.003 < 0.05 indicates that CR, DER, and DAR have a less significant correlation relationship with Return on Assets (ROA). A determination coefficient value of 0.382 showed that 38.2% of the ROA variables were influenced by CR and DAR, while the remaining 67.8% were explained by other factors outside the model. Overall, the research findings confirm the importance of efficient debt management and optimization of capital structure to increase the company's long-term profitability.

This study aims to analyze students' perceptions of the concept of meritocracy in education management as an effort to prevent nepotism in the recruitment process for elementary school teachers. Meritocracy is seen as an approach that emphasizes individual competence, qualifications, and achievements in the selection process for educators, while nepotism is often an obstacle in creating a professional and ethical educational environment. This study uses a quantitative descriptive method with data collection through questionnaires distributed to students in education study programs who have acquired a basic understanding of educational management and teacher recruitment systems. The data were analyzed to describe the students' level of understanding, attitudes, and views on the application of meritocracy principles and their awareness of the negative impacts of nepotism in the world of education. The results show that the majority of students have a positive perception of meritocracy as a fair and effective system for improving the quality of educators. However, some students acknowledge that nepotism is still common in the education sector and is considered to undermine professionalism and public trust. These findings emphasize the importance of instilling meritocratic values from the university level and strengthening competency-based recruitment policies to support the creation of a transparent and high-quality education system.

This study aims to analyze the errors made by eleventh-grade students of SMA Swasta Eria in solving word problems related to quadratic equations and quadratic function graphs using Newman’s error taxonomy. The research employed a descriptive qualitative method involving 25 students who were given essay-type tests to measure both conceptual understanding and problem-solving skills. Data were collected from students’ written answers and analyzed according to Newman’s stages, which include reading, comprehension, transformation, process skills, and encoding. The findings reveal that errors occurred across all stages, with transformation errors and encoding errors being the most dominant. These mistakes generally stemmed from students’ inability to extract key information into correct mathematical models, inaccuracies in arithmetic operations, and insufficient understanding of fundamental quadratic concepts and their graphical representations. The results highlight the importance of instructional approaches that emphasize conceptual understanding, varied practice problems, and proper mathematical notation. Regular application of Newman’s error analysis is expected to help teachers provide more targeted feedback and improve students’ problem-solving abilities.

The “turun ranjang” marriage is a traditional practice found in several Indonesian ethnic groups, in which a man marries the younger sister of his deceased or divorced wife. This tradition aims to maintain family harmony, protect children, and preserve kinship ties. From the perspective of Islamic law, such a marriage is permissible as long as it fulfills the legal requirements and pillars of marriage, including the presence of a guardian, witnesses, mutual consent, and the absence of coercion. However, if any of these conditions are not met, the marriage may be considered invalid according to Islamic law. While this tradition has positive aspects such as preventing adultery and preserving family unity it may also lead to social conflict when performed under pressure or without full consent. Therefore, it is essential for those involved to seek guidance from Islamic scholars or legal experts to ensure the marriage aligns with religious principles and promotes family harmony. Overall, the “turun ranjang” marriage can be accepted if conducted with sincerity, awareness, and compliance with Islamic law.

The concept of “urgent violation” as regulated in Article 52 paragraph (2) of Government Regulation No. 35 of 2021 introduces a new ground for employment termination (PHK), granting employers the authority to unilaterally terminate workers. However, this provision lacks a clear definition and objective parameters, creating legal uncertainty and potential misuse. This study employs a normative juridical method with a descriptive-analytical approach through literature review of legislation, Constitutional Court decisions, and labor law literature. The findings indicate that the clause on “urgent violation” often emerges from unequal bargaining positions between employers and workers, thereby failing to fully satisfy the principle of consensualism as a requirement for valid agreements. Substantively, this provision resembles the “serious misconduct” norm under Article 158 of the Manpower Law, which was annulled by the Constitutional Court through Decision No. 012/PUU-I/2003 for violating the presumption of innocence and workers’ constitutional rights. Consequently, the regulation on “urgent violation” risks repeating the same legal shortcomings and contradicts the spirit of labor law, which emphasizes that termination of employment must be avoided and only used as a last resort (ultimum remedium), as affirmed in Article 151 of the Manpower Law.
