Abstract

This paper describes the fate of customary land surrendered by indigenous peoples as part of the government's development programme to increase the palm oil plantation industry to support the economy and modernisation. The approach used is ethnography with a case study focus. Data were collected through interviews and observation techniques as well as literature study. informants were selected by grouping the interests of individuals and tribal groups (Ninik Mamak, Tanjung Tribe, KAN, Companies, Local Government, and Community Leaders). As a result, after the Nagari Bawan and Manggopoh communities surrendered their land to PT AMP Plantation with a mechanism that was considered in accordance with customary rules and applicable laws and regulations, it eventually led to conflict. The Ninik Mamak of Nagari Bawan was provoked into an internal conflict over who had the most authority in the land, and some Ninik Mamak used customary rules for political interests. Likewise, the community of Nagari Manggopoh, namely the Tanjung tribe, has ventured into conflict with plasma land management and maintaining the status quo as a full landowner. In addition, the Tanjung tribe experienced conflicts between fellow Ninik Mamak, who claimed that they had the most power over the control of plasma products and were entitled to personal benefits. They (the Tanjung tribe) are also in conflict with community groups, Ninik Mamak (KAN), and the company because of the lack of transparency in the provision of plasma distribution.

Abstract

Penelitian ini mengkaji struktur anatomi batang dan daun Anacardium occidentale dengan penekanan pada karakteristik serat serta bentuk adaptasi terhadap kondisi lingkungan kering. Pengamatan dilakukan secara mikroskopis menggunakan metode Free-hand Section untuk preparasi anatomi daun dan batang, serta metode maserasi untuk mengidentifikasi struktur serat dan trakea pada batang. Hasil pengamatan menunjukkan bahwa daun memiliki sel epidermis berbentuk poligonal tidak beraturan dan stomata bertipe anomositik. Struktur anatomi batang tersusun atas epidermis, korteks, xilem, dan floem. Melalui metode maserasi, serat xilem teridentifikasi sebagai sel-sel sklerenkim memanjang dengan ujung meruncing serta dinding sel sekunder yang sangat tebal akibat lignifikasi. Selain itu, trakea ditemukan dengan tipe penebalan dinding retikulat. Struktur tersebut terutama terlokalisasi pada xilem primer di daerah batang yang sedang mengalami pertumbuhan aktif. Temuan ini menunjukkan adanya karakter anatomi yang mendukung fungsi mekanik dan transport, sekaligus berperan dalam adaptasi tanaman terhadap kondisi lingkungan kering.

Abstract

This article examines the intricate relationship between the expansion of oil palm plantations and the preservation of customary (adat) systems in the villages of Salareh Aia Utara and Salareh Aia Barat, Agam Regency, West Sumatra. Employing a critical ethnographic approach, the study investigates how customary land, traditionally managed by Ninik Mamak (traditional leaders), has been transferred to private companies—particularly PT AMP Plantation—through adat-based agreements and compensation mechanisms. The research highlights the emergence of internal conflicts among traditional leaders, disputes over authority and compensation, and broader tensions between indigenous communities and corporate interests. Findings reveal that the process of land transfer, while formally adhering to customary and legal procedures, often leads to contestation, fragmentation of community leadership, and persistent disputes over land rights and plasma distribution. The article highlights the intricate interplay of economic, social, and political factors that influence these dynamics, underscoring the need for companies and policymakers to acknowledge the evolving nature of customary authority and the importance of culturally sensitive engagement. Ultimately, the study contributes to a deeper understanding of how modernisation and agribusiness intersect with indigenous rights and social structures in contemporary Minangkabau society.

Abstract

This research seeks to elucidate the conflict over PT PHP I's CultivationRights Title (HGU), claimed as customary land by some communities inNagari Kapa. It aims to detail the customary elements that legitimized the1997 land rights transfer to the West Pasaman Regency government. Theissue stems from internal conflicts among Nagari Kapa's customary elites,impacting PT PHP I as the HGU holder. The disputed area encompasses 315hectares of PT PHP I's land, occupied by the community since 2020. Usingethnographic methods, the study explores community and tribal leaders'(Ninik Mamak) perspectives on customs and land status. Interviews wereconducted with 10 groups of tenant farmers on PT PHP I's core HGU landand 5 Ninik Mamak. Findings reveal that land status, under the BabingkahAdat system, is determined by the Pucuk Adat and transferred according toAdat Diisi Limbago Dituang and Siliah Jariah customary requirements.However, some community members oppose this mechanism, occupying landdesignated as PT PHP I's HGU, and thus, they collectively claim the land ascustomary territory of the Nagari Kapa community.
