The Yogyakarta Forest Management Unit (FMU) manages the Sendang Mole Cajuput<br />plantation forest and the oil factory. This research aimed to analyze the production costs, business feasibility, and sensitivity to changes in market conditions that may affect the company's viability. Data were collected through interviews, observations, and financial documents from 2018 to 2022. Financial feasibility indicators include profit, Cost-to-Income Ratio (CIR), Return on Investment (ROI), and sensitivity to changes in yields and raw material prices. The results showed an average annual profit of IDR 610,863,515, an Income Ratio of 88.36%, and an ROI of 13.18%. These indicated the business was financially viable and profitable. Sensitivity analysis demonstrated that the business was highly sensitive to cajuput oil selling price reductions, becoming unfeasible at IDR 190,100/L and reaching break-even at IDR 212,408/L, while remaining feasible under a 10% decline in the yield and a 20% increase in raw material costs. </p>2026-09-17T00:00:00+07:00Copyright (c) 2026 Achmaludin Taufan Azmi, Agus Affianto, Dwiko Budi Permadihttps://jurnal.ugm.ac.id/v3/jik/article/view/27128Legal Pluralism and Customary Forest Governance: Customary Community-Based Zoning and Institutional Adaptation in Yongsu Desoyo, Papua2026-08-03T19:47:45+07:00Normalia Ode Yanthynormaliaodeyanthy@gmail.comYannice Luma Marnala Sitorusnalaustj2006@gmail.comAnna Mariani Labokanna.marialabok@yahoo.com<div> <div>Customary forest governance in Papua reflected the complex dynamics of legal pluralism, where state and customary law interacted in the management of community living spaces. This research aimed to analyze the governance of the indigenous forest by the Yongsu Desoyo community through a traditional zoning system consisting of sena, buso, and sasena as cultivation land, utilization zone, and sacred zone. The response of customary institutions, particularly keret and ondoafi, to external pressures and socioecological change was also examined. Data were collected through in-depth interviews, participant observation, and document analysis. The results showed that forest management practices in Yongsu Desoyo embodied key principles of Community-Based Natural Resource Management (CBNRM). The customary zoning system contributed to maintaining the ecological functions of the forest, strengthening social legitimacy, regenerating customary values, and promoting ecological justice. Furthermore, institutional adaptation and the active participation of youth were crucial to sustaining customary forest governance in the context of power asymmetries and limited legal recognition by the state. Customary forest governance in Yongsu Desoyo reported the potential of a co-governance approach that combined the strengths of Customary institutions with formal policy support. This offered a strategic pathway for enhancing the sustainability of forests and advancing justice in conservation.</div> </div>2026-10-13T00:00:00+07:00Copyright (c) 2026 Normalia Ode Yanthy, Yannice Luma Marnala Sitorus, Anna Mariani Labok
