Full text linkThis article or paper aims to analyze the ideological construction of the Hanura Party, namely "Religious Nationalist," about the regeneration process in Medan. In addition, this study also aims to evaluate the electability of candidates for the Hanura Party legislative members in Medan City by applying the ideology of "Religious Nationalists." This study uses a qualitative research method with a type of descriptive research, using primary and secondary data collection techniques. Primary data in this Thesis was obtained through interviews and observations, while secondary data was obtained through books, journals, and the Internet. Research shows that the religious nationalist ideology of the Hanura Party plays a vital role in shaping the political identity, loyalty, and ethics of cadres in the city of Medan. However, the challenge of internalizing ideology underscores the need to strengthen the regeneration program, especially in connecting ideological teaching with field practice. The success of cadre regeneration requires the development of technical competence to deal with political dynamics, so the Hanura Party needs to innovate in forming cadres who are loyal to ideology and politically competent
Policy Analysis of the Occupational Safety and Health Management System of SMK3 at the North Sumatra Provincial Employment Supervision UPTD
Full text linkThis study aims to analyze the policies of the Occupational Safety and Health Management System (SMK3) implemented in the North Sumatra Provincial Manpower Supervision UPTD. A qualitative approach is used to explore the effectiveness of policies, implementation challenges, and their impact on occupational safety. Data were obtained through in-depth interviews, field observations, and document analysis. The results of the study show that the SMK3 policy has positively impacted reducing the number of work accidents, especially in companies that consistently implement safety standards. However, its implementation is still constrained by limited resources, a low understanding of small and medium enterprises (SMEs) regulations, and a lack of labor participation in several companies. Management commitment and occupational safety culture have proven to be key factors in successfully implementing SMK3. In addition, digital technology has begun to support supervision, although it still requires development. This study recommends increasing the capacity of supervisors, more intensive policy socialization, and collaboration with K3 training institutions. With a more inclusive and technology-based approach, the SMK3 policy is expected to improve overall occupational safety in North Sumatra Province

Madurese Men's Sinden or Lengge's Resistance to Gender Construction
Full text linkMadurese Sandur's art is unique in that those who play the role of sinden or lengge' are men. On the other hand, in gender construction, the roles of men and women are divided. In the field of work, men must have masculine professions, and women must have feminine professions. Because of this construction, someone can experience gender bias. This study aims to describe the form of resistance of Madurese male sinden or lengge' to gender construction. The method used is qualitative with a phenomenological approach. In addition, this study technique uses observation, interviews, documentation, and literature studies. The results show that Madurese male lengge experience negative stereotypes, namely that male lengge' are considered transvestites and like women. The existence of these stereotypes causes male lengge' to resist. The resistance carried out is only to suppress feelings every time someone labels him as a transvestite. This shows that Madurese male lengge' carries out closed resistance. Open resistance is also carried out by showing the fame of male lengge'. They prove that being a lengge' is not easy, this is proven by the fact that there is no regeneration of male lengge' in the Madurese sandur art
The Role of the Regional Disaster Management Agency (BPBD) in Preventing Flood Disasters in Mandailing Natal Regency
Full text linkHigher than usual rainfall and an inability to absorb water optimally have caused flooding in Mandailing Natal Regency. Geographical conditions that include mountains, highlands, lowlands, and coasts also contribute to the potential for complex disasters. This study aims to analyze the role of the Regional Disaster Management Agency (BPBD) in flood prevention and identify inhibiting factors. A qualitative descriptive approach was used, with data obtained through interviews, observations, and documentation. The results of the study indicate that BPBD carries out its role through pre-disaster mitigation, including media appeals, training, construction of safety structures, non-structural mitigation based on community empowerment, and the establishment of Disaster Resilient Villages. At the emergency response stage, BPBD deploys a Rapid Reaction Team (TRC) to assess the situation, while post-disaster recovery is carried out through infrastructure reconstruction, victim trauma assistance, establishment of command posts, damage inventory, and evaluation. The main obstacles include budget limitations and cross-sector coordination. The conclusion of this study confirms that optimizing the role of BPBD requires better synergy with the central government and the community to increase the effectiveness of flood prevention and handling in Mandailing Natal
