Lake Toba, designated as a National Tourism Strategic Area, faces ecological disruption due to the invasive Red Devil fish (Amphilophus labiatus), which threatens the sustainability of native aquatic species. This study aims to enhance the knowledge of the Tapian Nauli farmer group in Hariara Pohan Village, Samosir Regency, in utilizing the Red Devil fish as Liquid Organic Fertilizer (LOF) and processed food. Methods employed include agricultural extension activities, practical demonstrations, pre-tests and post-tests, and evaluation through questionnaires. Results showed a significant improvement in farmers' knowledge after the extension, with 70% moving from the "poor" to "good" category. The Red Devil fish was successfully processed into LOF through fermentation using molasses, starbio, and pineapple, and into shredded fish (abon) as a food product. Farmers responded positively to the idea of Red Devil abon as a potential household business opportunity, given the fish's abundance and low cost. Evaluation of the extension activities revealed a high level of suitability with an average score of 96.33%, covering material content, delivery methods, and instructional media. This study demonstrates that locally based extension approaches can effectively empower farmers to convert invasive pests into value-added products, while fostering economic opportunities rooted in local resources.

This study aims to examine the existence of the Church in the context of salvation history from the perspective of systematic theology, focusing on the role and vocation of the ecclesia as the community of God's people. The background of this study departs from the belief that the Church is not just a religious institution, but has an existential and historical basis in God's saving work. The Church acts as an extension of Christ's mission which is continued in the power of the Holy Spirit. In this research, the author uses a qualitative method with a literature study approach. The data sources consist of the Holy Bible, theological books related to the title, as well as relevant theological journal articles. This research was conducted to understand the relationship between the Church's identity and its participation in salvation history, both dogmatically and functionally. The results show that the Church is called to be an active witness in the work of salvation, by carrying out prophetic, liturgical, and social functions. As an ecclesia, the Church is not just a collection of individual believers, but a community that lives in relationship with Christ as the Head. The discussion emphasizes that the Church has a mandate to live in unity, holiness, catholicity, and apostolate, all of which are rooted in God's grace. In conclusion, the existence of the Church in salvation history is eschatological and missionary. The Church is called to be a sign and means of salvation, and to take part in the salvation of the world.

This study is based on the urgency to understand Calvinism, one of the most influential theological systems in the history of Christianity, which originated from the thoughts of John Calvin in the 16th century. This theology emphasizes the sovereignty of God in the process of salvation, formulated in five core doctrines known by the acronym TULIP: Total Depravity, Unconditional Election, Limited Atonement, Irresistible Grace, and Perseverance of the Saints. The research adopts a qualitative descriptive approach using a library research method, aiming to explore the theological concept of Calvinism through the analysis of theological, historical, and doctrinal literature. The findings reveal that Calvinism forms a systematic theology of salvation that is entirely centered on God’s grace, without reliance on human effort. Additionally, the study highlights how Calvinist teachings have significantly influenced Christian life and church practices, both historically and in the present day. Therefore, it is important for these teachings to be understood and applied contextually in Indonesia, to remain relevant and avoid being misinterpreted as rigid or fatalistic doctrine.

Osha Snack UMKM faces issues related to product defects, which are suspected to arise due to a lack of quality control in the production process. This study aims to identify the causes of product defects, provide improvement suggestions, and determine effective ways to control product quality. Data were collected through interviews with relevant parties and field surveys to gather information on production volume, product defects, and production activities. The data were processed by organizing it into check sheets, performing regression calculations, and analyzing it using scatter diagrams and fishbone analysis. The Statistical Process Control (SPC) method was applied to analyze, control, and improve the production process. The results show a significant relationship between production volume and the number of defective products, with the regression equation Y = 0.0764X and a coefficient of determination R² = 0.9625. The most common type of defect is broken snacks before packaging. In addition, waste products also come from product returns by buyers, which leads to raw material waste and hinders the achievement of production targets. The analysis results suggest that the UMKM should implement quality control measures in the form of process improvements, enhancement of work skills, proper machine maintenance, implementation of SOPs, and improvement of working conditions.

High blood triglyceride levels indicate impaired fat metabolism and can trigger atherosclerosis, making hypertriglyceridemia a major risk factor for cardiovascular disease (CVD), metabolic syndrome, and acute pancreatitis. The productive-age population often experiences overnutrition due to unhealthy diets and low physical activity, increasing fat and triglyceride accumulation. Stress may also elevate triglyceride levels, necessitating early screening. The Community Service Program (PKM) at Assisi Church aimed to raise awareness of early dyslipidemia detection through triglyceride screening using Point-of-Care Testing (POCT) and educational counseling. Among 76 participants, 39 (57.35%) had high triglyceride levels, while 29 (42.65%) were normal. These findings highlight the importance of regular check-ups and continuous education to reduce cardiometabolic risks and promote healthier lifestyles.

This research examines God as the initiator of cross-cultural missions through a case study of mission transformation in the life of the Apostle Peter. Departing from the existing research gap, namely the need to reflect on the nature of God who loves other nations through a change in Peter's perspective, this study aims to show that God is the initiator of salvation for all mankind. The significance of this study is to encourage the church to see cross-cultural missions as an important approach in transmitting God's love to those who have not yet repented. Using a descriptive-analytical method, this study finds that Peter's encounter with Cornelius was a crucial turning point in early Christian missionary work. The experience radically changed Peter's narrow understanding of who was worthy of receiving the gospel, extending from just Jews to all nations. The descent of the Holy Spirit upon Cornelius and his family is clear evidence to Peter that God's grace is impartial and available to every believer. This event was not only a personal lesson for Peter, but also a revelation of God that opened the door for the gospel to reach the Gentile world, fundamentally changing the course of church history.   Penelitian ini mengkaji Allah sebagai penggagas misi lintas budaya melalui studi kasus transformasi misi dalam kehidupan Rasul Petrus. Berangkat dari kesenjangan penelitian yang ada, yaitu kebutuhan untuk merefleksikan sifat Allah yang mengasihi bangsa lain melalui perubahan cara pandang Petrus, studi ini bertujuan untuk menunjukkan bahwa Allah adalah inisiator keselamatan bagi seluruh umat manusia. Signifikansi penelitian ini adalah untuk mendorong gereja agar melihat misi lintas budaya sebagai pendekatan penting dalam menularkan kasih Allah kepada mereka yang belum bertobat. Dengan menggunakan metode deskriptif-analitis, penelitian ini menemukan bahwa perjumpaan Petrus dengan Kornelius merupakan titik balik krusial dalam karya misi Kekristenan awal. Pengalaman tersebut secara radikal mengubah pemahaman sempit Petrus mengenai siapa yang layak menerima Injil, meluas dari hanya orang Yahudi menjadi semua bangsa. Turunnya Roh Kudus kepada Kornelius dan keluarganya menjadi bukti nyata bagi Petrus bahwa kasih karunia Allah tidak memandang bulu dan tersedia bagi setiap orang yang percaya. Peristiwa ini tidak hanya menjadi pelajaran pribadi bagi Petrus, melainkan juga wahyu Allah yang membuka pintu bagi Injil untuk menjangkau dunia non-Yahudi, secara fundamental mengubah arah sejarah gereja.

Customary land is an integral part of the identity and survival of customary law communities, including in the Kampar region, Riau Province. However, along with increasing investment and development, there have been various forms of takeover of customary land rights that have triggered disputes between customary communities and third parties, such as private companies and the government. This study aims to analyze the mechanism for resolving disputes over the takeover of customary land rights in the Kampar region using customary law and national law approaches. The method used is a combination of normative and empirical juridical, data obtained through legal document studies, interviews with authorized local customary leaders. The results of the study show that customary communities in Kampar still rely on customary resolution mechanisms. Meanwhile, in resolving litigation, they often experience administrative and economic obstacles, while non-litigation channels such as multistakeholder mediation and administrative recognition by the local government are more effective if supported by policies that support them. In conclusion, synergy between customary law and national law is absolutely necessary to create fair protection for the rights of indigenous peoples, and it is hoped that there will be strengthening of customary institutions, acceleration of recognition of customary areas through regional regulations, and preparation of integrated mechanisms for resolving disputes based on local culture and national legal certainty.

Misuse of accounts linked to telephone numbers has become a serious issue in the realm of cybercrime. This often happens when a user's telephone number is inactive or has entered a grace period, and is then resold by the provider to a third party. This creates an opening for hackers to access accounts associated with that number, including banking and e-commerce accounts. By utilizing the information obtained, hackers can carry out illegal transactions that harm genuine users. This article was created to analysis the mechanisms of abuse in the context of cybercrime, as well as the psychological and financial impacts experienced by victims. The results of this case analysis show that a lack of awareness of cyber security and personal data protection increases the risk of misuse, making it important for users to implement stricter security measures.

The reservoir is assumed to be a perfect cylinder with a radius of 564 meters and a depth of 8.45 meters. The volume is calculated using both the shell method and the standard analytical formula for cylinders. The result shows a water volume of 8,437,640.45 m³. Both methods produced identical results with an absolute error of 0.00 m³. This proves that the shell method is highly accurate for symmetrical reservoir shapes. The study demonstrates how integral calculus can be applied to real-world problems in hydrology.

This article examines Christian inclusivism through the theological tension between the centrality of Christ and the breadth of God’s grace in the context of the contemporary Indonesian church. Using a qualitative library-based and constructive-theological approach, the study analyzes the concepts of wider hope, general revelation, fulfillment model, Karl Rahner’s anonymous Christianity, and evangelical inclusivism. The article argues that Christian inclusivism is not a weak compromise between exclusivism and pluralism, but a constructive framework that preserves Christ as the center of salvation while acknowledging the possibility of divine work beyond the formal boundaries of the church. In Indonesia’s multireligious society, this model helps the church develop a faithful yet dialogical public presence. It supports witness without coercion, interfaith dialogue without the loss of Christian identity, and social cooperation without relativizing Christ. Furthermore, inclusivism encourages the church to articulate its faith with humility, openness, and responsibility. Thus, inclusivism offers a relevant theology of religions for ecclesial life, mission, and public engagement in contemporary Indonesia.

This study explores the application of the normal distribution in analyzing the height data of Mathematics Education students at FMIPA Universitas Negeri Medan in 2024. Employing a quantitative descriptive-analytic methodology, the research involved collecting primary data from 10 randomly selected students through a questionnaire-based survey. Descriptive statistical analysis revealed a mean height of 161.4 cm with a standard deviation of 8.79 cm. The median height was found to be 164 cm, while the mode was 150 cm, indicating a slightly skewed distribution. To assess the suitability of the normal distribution model, the Shapiro-Wilk test was applied, resulting in a W value of 0.921 and a p-value of 0.361, which exceeds the 0.05 significance level. This confirms that the sample data follow a normal distribution pattern. The findings were further supported through visual representation using histograms and analysis based on the empirical rule, which showed that approximately 68% of the students' heights fall within one standard deviation of the mean (152.81–169.99 cm). Additionally, probability calculations demonstrated that the likelihood of a student being 160 cm tall or shorter is approximately 43.64%. These results validate the effectiveness of the normal distribution as a tool for analyzing biological or physical characteristics, even in small sample sizes. However, the study acknowledges its limitation in terms of sample size and suggests that future research involve larger and more diverse populations to enhance generalizability. The study highlights the relevance of normal distribution in statistical modeling, particularly for educational and health-related data interpretation and decision-making processes.

The Protestant Reformation had a significant impact on the development of Christian theology, especially in the field of Christology. This study aims to examine the thoughts of Martin Luther and John Calvin regarding the role of Christ in the process of human salvation. The method used is a qualitative approach with a literature study technique, which examines the theological works of the two Reformers. The results of the study show that Luther emphasized the personal relationship between humans and Christ as savings, as well as the real presence of Christ in the sacrament as a form of God's grace that can be experienced personally. Meanwhile, Calvin developed the concept of three placements of Christ as prophet, priest, and king which emphasized the overall role of Christ in salvation, and viewed the sacrament as a spiritual means to strengthen the faith of believers. Through this study, it can be concluded that Christology in the Reformation tradition provides a strong, systematic, and relevant theological basis for the development of contemporary Protestant teachings, both in doctrinal aspects and the practice of life of faith.

Sola fide is the main Reformed teaching that salvation is only obtained through faith alone, not through charity or good deeds. in the 16th century the practice of indulgences and the Catholic church's emphasis on good works gave rise to doubts in the faith, which later gave rise to the Reform Movement. In response, the reformers restored the principle of sola fide to protect believers in the Lord Jesus from doubts about their Faith. The aim of this research is to analyze the role of sola fide in strengthening believers' faith before reform skepticism, through a literature review of the writings of reformer figures. The results show that emphasizing God's sovereign grace, the sufficiency of faith for forgiveness of sins and assurance of salvation, and sola fide can strengthen believers' faith against attacks of skepticism. This understanding provides important insight for believers today about how to strengthen their faith in the face of increasing skepticism. Overall, this research shows the central role of the principle of sola fide in the history of Christian thought.

The development of digital technology has transformed how university students access and process information. Digital literacy has become an essential skill encompassing the ability to search for, evaluate, and effectively use information. This study aims to analyze the factors influencing university students' digital literacy, the role of technology in supporting these skills, and effective strategies that can be implemented to improve digital literacy in academic environments. The research method employed is a mixed-method approach with data collection techniques through digital questionnaires administered to 25 students from various majors, as well as a literature review from various sources. The results of the study show that 52% of students use the internet for more than six hours a day, 83.3% actively seek information daily, and 60% always verify information before sharing it. The main obstacles in improving digital literacy include limited access to digital learning resources (54.2%) and a lack of literacy training (54.2%). Proposed strategies to address these challenges include integrating digital literacy materials into the curriculum, organizing regular training and seminars, and optimizing the use of educational technology platforms. The conclusion of this study emphasizes that digital literacy is not just about technical skills but also involves critical thinking and filtering accurate information. Therefore, systematic efforts are needed from various parties, including universities, lecturers, and students, to create an academic environment that supports the optimal development of digital literacy.

This research aims to analyze how the church in the old and new testaments. The approach used in this research is descriptive qualitative, which aims to understand the structure so that it has a major influence on contemporary Christianity. From a conceptual perspective, the Church in the Old Testament is understood as a community of God's chosen people whose identity is attached to the ethnic unity of the Israelites and attachment to the law within the framework of the covenant. While in the New Testament, the understanding of the Church undergoes a transformation into a universal, inclusive, and spiritual community of faith, consisting of all people who believe in Jesus Christ as Lord and Savior, without ethnic or legal restrictions. In terms of structure and leadership, the Old Testament features a leadership system based on heredity and institutional positions such as priests and prophets who mediate the people's relationship with God; whereas in the New Testament, leadership is no longer hereditary, but based on the gift of the Holy Spirit, with a collegial, functional and participatory service model and Christ as the Head of the Church, emphasizing the dimensions of relationships and service in the community.In terms of sacraments, religious practices in the Old Testament such as religious celebrations functioned as symbols of obedience and identity of the people's covenant with God, but in the New Testament, so the sacramental meaning is renewed through baptism and holy communion which are spiritual and Christocentric, marking new fellowship in Christ in the context of grace. This study concludes that the New Testament cannot be understood as a break with or an abolition of the traditions and practices that existed in the Old Testament. Instead, the New Testament represents a theological fulfillment and essential transformation of the entire narrative and system that had been built in the Old Testament.
