The Authority of Labuhanbatu Utara Regency Government in Fulfilling Plasma Rights for the Community in Merbau Selatan (A Study on PT. Perkebunan Nusantara IV Regional I)
No full textThe ongoing conflict between the community in Merbau Selatan and PTPN III reflects the lack of attention from the local government. Additionally, PTPN III is obligated to allocate 20% of its HGU (Right to Cultivate) land for the development of community plantations. This study examines the regulations related to plasma rights for the community, the authority of the Labuhanbatu Utara Regency Government in fulfilling plasma rights, and the efforts that can be undertaken by the local government to address the issues surrounding plasma rights in Merbau Selatan. This research adopts a normative juridical method by analyzing legal theories, principles, and regulations relevant to the subject matter.
The study reveals that the obligation to allocate 20% of HGU land for community plantations is mandated by Article 58 of Law No. 6 of 2023 on the amendment to Government Regulation in Lieu of Law No. 2 of 2022 on Job Creation. Failure to comply with this obligation may result in administrative sanctions as stipulated in Article 60 of Law No. 39 of 2014 on Plantations. However, the Labuhanbatu Utara Regency Government, through the Agriculture Office, has not imposed any administrative sanctions on PTPN III despite non-compliance. Raising awareness among companies about their rights and obligations is crucial to prevent violations in the implementation of partnership programs. Furthermore, increased supervision and protection for plasma farmers are necessary. The enactment of a Regional Regulation on the Protection of Plasma Farmers is recommended to ensure legal certainty, improve income, and enhance the welfare of communities around the plantation.154 PagesTesis Magiste

Analysis of the Economic and Social Needs of Poor Fishermen Communities in Paluh Sibaji Village, Pantai Labu District, Deli Serdang Regency
No full textIndonesia, as an archipelagic country, has vast potential in marine resources; however, the welfare of poor fishing communities remains far from satisfactory due to various economic and social limitations. This study aims to analyze the economic and social needs of poor fishermen who face challenges such as low income, limited access to education and healthcare, and dependence on middlemen. The research was conducted in Paluh Sibaji Village, Pantai Labu Subdistrict, Deli Serdang Regency. The key informant was the Head of Paluh Sibaji Village, with three poor fishermen serving as main informants and fishermen’s families as additional informants. Data collection was carried out through literature review and field studies, including observation, interviews, and documentation. The data obtained in the field were then qualitatively analyzed until conclusions could be drawn. Based on the findings, the living conditions of poor fishermen in Paluh Sibaji Village reveal ongoing multidimensional economic and social needs. Referring to Sukirno’s (2005) theory of economic needs, it is evident that low per capita income, limited employment opportunities, unequal income distribution, and inadequate economic infrastructure persist. An analysis based on Abraham Maslow’s (1943) theory of social needs indicates that poor fishermen in Paluh Sibaji experience a sense of belonging and social bonds, love and affection, as well as social interactions within the community, although these remain limited and not yet optimal.119 PagesSkripsi Sarjan
