Livestock production in rural communities relies heavily on the availability and quality of animal feed. In Aek Korsik Village, Asahan Regency, farmers continue to use manual methods to chop forage, which are time-consuming, inconsistent, and physically demanding. To address these issues, a portable forage chopper machine was designed and introduced through a community service program (KKN). The machine features a compact mechanical system powered by a small motor, making it lightweight, mobile, and easy to operate in various conditions. The implementation process included three stages: machine development, field testing, and community training. During testing, the machine efficiently processed forage materials like grass, corn stalks, and agricultural residues, producing uniform feed sizes much faster than manual methods. Farmers reported reduced workload, improved availability of chopped forage, and better livestock feeding practices. The portable design allowed the equipment to be shared among farming groups, fostering cooperation. This study underscores the role of appropriate technology in addressing rural agricultural challenges. By integrating engineering innovation with community service, the portable forage chopper machine enhances technical efficiency and socio-economic empowerment for farmers. Future improvements should focus on durability, cutting capacity, and sustainable energy alternatives to better meet the needs of smallholder farmers.

Criminal law based on genetic determinism was once rejected in modern criminal law systems because it was deemed contrary to the principle of individual responsibility. However, the rise of epigenetics and neurocriminology in contemporary legal practice indicates a reconstitution of the biological basis for attribution of criminal culpability. This study aims to analyze the extent to which developments in epigenetics reopen opportunities for the operation of biological approaches in criminal law, while also critiquing the conceptual dangers they pose to the principles of justice and moral responsibility. The research method uses a normative legal approach with a conceptual approach. The results show that epigenetics works as a tool for scientific validation of the formation of risk categories in criminal law, while simultaneously weakening the perpetrator's position as a moral subject. The criminal law structure that technocratically accepts biological arguments creates a new form of legal exclusion through medical classifications that are not open to ethical evaluation. In this situation, the law operates as an instrument of biological management of bodies deemed deviant. The position of neurocriminology in this case is no longer merely a tool, but rather the center of the configuration of biolegal power that defines responsibility based on predisposition, not will. Therefore, a new normative framework is needed that can uphold the principle of individual responsibility while rejecting the ethical reduction of biological diagnoses in the criminal law system.

Believers, both in the time of Jesus and in today’s context, live in situations shaped by social, political, economic, religious, and cultural influences that often give rise to anxiety and doubt about God’s providence. In Luke 12:22–32, Jesus delivers a teaching that prohibits worry and calls His followers to direct their hearts toward the Kingdom of God. For those living under Roman rule, these words were a source of comfort and encouragement to remain steadfast in their faith in God’s power, and for believers today, the same message continues to be relevant as guidance for managing worry with trust and hope. This study seeks to analyze Luke 12:22–32 from the perspective of the theology of God’s providence and to explain its implications for contemporary Christian life. The findings emphasize three key points: first, the passage affirms God as a sovereign, loving Father who cares deeply for His people; second, God’s providence includes both physical and spiritual needs, thus framing faith as an active trust that combines prayer, hope, and concrete action; and third, reflection on God’s providence strengthens believers to face modern anxieties by prioritizing the Kingdom of God, practicing spiritual discipline, and embodying solidarity with others. Although limited in scope as a textual study without cultural or empirical application, this research contributes significantly to understanding God’s providence in Luke 12:22–32 and underlines its relevance for addressing contemporary challenges while encouraging Christians to live out their faith in tangible ways.

A partnership agreement is a form of business collaboration, either directly or indirectly, that is established based on the principles of mutual need, mutual trust, mutual reinforcement, and mutual benefit. Such partnerships generally involve Micro, Small, and Medium Enterprises (MSMEs) working with larger businesses in order to create a fairer and more sustainable business relationship. However, in practice, the implementation of partnership agreements often does not reflect these fundamental principles. This is also evident in the nucleus-plasma scheme within the palm oil plantation sector, where the relationship between the nucleus companies and plasma farmers tends to show an imbalance of bargaining power. This study aims to examine the application of partnership principles in the implementation of nucleus-plasma agreements in palm oil plantations, viewed from the perspective of prevailing legislation, particularly the Law on Micro, Small, and Medium Enterprises (MSME Law). The findings indicate that the application of partnership principles has not yet been fully implemented consistently. The partnership relationship remains unequal and is largely dominated by the nucleus companies, creating a sense of injustice for plasma farmers. In terms of supervision, the Indonesian Business Competition Supervisory Commission (KPPU) plays a crucial role in ensuring that partnership agreements are carried out in line with these principles. One of the measures taken is monitoring the implementation of behavioral change commitments by business actors. KPPU ensures that nucleus companies do not abuse their dominant position and continue to provide fair opportunities for plasma farmers. Therefore, this study highlights the importance of strengthening oversight and enforcing regulations so that the objectives of nucleus-plasma partnerships in palm oil plantations can truly be realized in accordance with the principles mandated by law.

This article examines the legal consequences of a delayed notification of a share acquisition under Indonesian competition law, focusing on the case of PT X's takeover of PT Y. The central issue is PT X's failure to report the acquisition to the Commission for the Supervision of Business Competition (KPPU) within the mandated 30-day period, as stipulated by Law Number 5 of 1999 and its implementing regulation, Government Regulation Number 57 of 2010. The notification was submitted with a significant delay of 2,023 days, a clear violation of the statutory requirements. As a result of this non-compliance, the KPPU, through its Decision No. 31/KPPU-M/2020, imposed an administrative fine on PT X amounting to   IDR 1,050,000,000.00 (one billion fifty million rupiah). Beyond the direct financial penalty, the violation led to severe indirect repercussions, including significant    reputational damage, which threatened to erode investor confidence and disrupt existing business relationships. The KPPU's firm and consistent enforcement in this case highlights the critical function of the post-merger notification system in Indonesia as a preventative mechanism to assess transactions that could lead to excessive market concentration. The decision underscores the legal principles of     transparency, fairness, and accountability that underpin Indonesian competition law. This case serves as a powerful deterrent, signaling to all business actors that non-compliance will not be tolerated. Ultimately, such rigorous enforcement is crucial for fostering a culture of legal adherence, maintaining market integrity, and building a more transparent and competitive business ecosystem that supports sustainable economic growth in Indonesia.

Renewable energy is non-fossil energy that can be renewed and managed sustainably, such as solar, wind, water, and biomass. To overcome dependence on weather conditions, this energy can be combined with alternative energy sources such as piezoelectric sensors, which can convert pressure into electrical energy. This study aims to design a prototype monitoring system for hybrid electric energy using solar panels, wind turbines, and piezoelectric elements as alternative energy sources on board ships. The use of Internet of Things (IoT) technology is key to monitoring and managing these energy sources in real-time and automatically through integrated sensors and software. This research uses the Research and Development (R&D) method by creating a prototype that combines solar panels, wind turbines, and piezoelectric components as energy sources and designing a monitoring system based on the Internet of Things (IoT) using the Kodular application. Several system components were tested through two types of testing: static and dynamic testing. The test results showed that the solar panel had the most stable performance with a voltage of approximately 16.50V and a current of 2.41A occurring between 13:00 and 16:00 WIB. The wind turbine was able to operate at low wind speeds and reached its highest voltage of 3.63V and current of 1.14A on the fifth day at 20:00 WIB with a wind speed of 1.1 knots. The piezoelectric system generated power according to the pressure and frequency of footstep impacts. The highest voltage recorded for a 70kg subject was 4.11V with a current of 0.19A. This hybrid system has the potential to be an environmentally friendly energy support solution on board ships.

Regulatory changes through Law No. 3 of 2024 concerning the Second Amendment to Law No. 6 of 2014 stipulate an extension of the village head's term of office from six to eight years. This policy is intended to strengthen leadership stability and the sustainability of village development, but also raises concerns regarding reduced leadership circulation, weakened community political participation, and increased potential for abuse of power. This research uses empirical legal methods with sociological, conceptual, and case-based approaches, conducted through field observations and in-depth interviews with village officials, community leaders, MSMEs, and residents of Kerato Village. The results show a diverse response from the community. Some support this policy because it is seen as providing the village head with the opportunity to complete development programs sustainably. However, others reject it, arguing that term extension has the potential to reduce the quality of local democracy, limit leadership regeneration, and reduce the frequency of community political participation. The discussion emphasizes the dilemma between village government stability and the principles of participatory democracy. In conclusion, this policy is ambivalent: positive in maintaining development continuity, but risky for accountability and community participation. Therefore, strengthening the function of the Village Consultative Body (BPD), transparency, and effective oversight mechanisms are very necessary to maintain the balance between government stability and village democracy.
