Abstract

This study aims to determine the effect of polyethylene (HDPE) adhesive percentage on the physical and mechanical properties of Wood Plastic Composite (WPC) made from Dipterocarpus spp. (keruing) sawdust. The research is driven by the decreasing availability of natural wood and the increasing volume of plastic waste, highlighting the need for innovative, environmentally friendly, and sustainable material alternatives. The method used was a Completely Randomized Design (CRD) with five treatment compositions of keruing sawdust and polyethylene: A (80:20), B (75:25), C (70:30), D (65:35), and E (60:40), each with three replications. The observed parameters included physical properties (density, moisture content, water absorption, and thickness swelling) and mechanical properties (Modulus of Rupture/MOR and Modulus of Elasticity/MOE). Data were analyzed using ANOVA followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level.The results showed that increasing the proportion of polyethylene significantly affected most physical and mechanical properties of WPC. The highest density (1.1 g/cm³) was observed in treatments D and E, although not significantly different statistically. Moisture content, water absorption, and thickness swelling decreased significantly with increased adhesive. The best performance was found in treatment E (60% wood, 40% polyethylene) with moisture content at 1.54%, water absorption at 197.82%, and thickness swelling at 9.19%, meeting the JIS A 5908-2003 standard. Mechanically, MOR and MOE values also increased, with the highest values recorded at 99.47 kgf/cm² and 30 kgf/cm², respectively, although still below JIS standards. In conclusion, increasing the proportion of polyethylene adhesive improves both physical and mechanical properties of keruing-based WPC. A formulation of 60% keruing sawdust and 40% polyethylene is recommended as the optimal composition for producing high-quality WPC from wood and plastic waste. Keyword: Wood Plastic Composite, polyethylene, keruing sawdust, physical properties, mechanical properties, HDPE.

Abstract

The Harau Valley Nature Tourism Park (TWA) faces complex sustainability challenges, with an increase in tourist visits reaching 270,790 visitors in 2022. This has led to ecological pressure, multi-stakeholder conflicts, and ambiguity regarding the destination's identity between conservation and commercial functions. This Systematic Literature Review (SLR) analyzes the multidimensional sustainability status (ecological, socio-cultural, economic, infrastructure), identifies gaps between formal public policy frameworks and field implementation practices, and formulates evidence-based, integrative policy recommendations. The study analyzes five peer-reviewed articles (2017-2024) using a multidimensional framework with MDS (Multidimensional Scaling), TALC (Tourist Area Life Cycle), and GRADE evidence synthesis. Inclusion criteria: publications in Indonesian/English, quantitative/qualitative/mixed-methods methodologies, field-based empirical research. The multidimensional sustainability index reached 59.45 (moderately sustainable) with dimension heterogeneity: ecology 66.52, infrastructure 65.66, economy 54.14, socio-culture 51.48. The optimal carrying capacity is 315,169 people/year, but temporal distribution is uneven, creating seasonal pressure. A significant gap was identified between formal regulations (Ministerial Decree, Regional Regulation) and implementation practices. The local leadership model of Tungku Tigo Sajarangan offers potential conflict resolution mechanisms for stakeholders. The Harau Valley Nature Tourism Park requires an integrative policy framework that balances conservation objectives, local livelihoods, and visitor satisfaction through community-centered governance, evidence-based quota systems, and the revitalization of traditional local leadership. A phased implementation is recommended, focusing on critical infrastructure (0-1 year), governance restructuring (1-3 years), and long-term ecological conservation (3-5 years).

Abstract

Mining activities constitute a high-risk industry that requires the implementation of a structured, measurable safety management system in compliance with regulatory requirements. The Mining Safety Management System (SMKP) is mandatory for all mining companies and mining service companies as a primary instrument for protecting occupational safety and the environment. However, research findings at PT Adaro Tirta Sarana indicate that the level of SMKP implementation has only reached 57.08%, which remains below the minimum standard of 75% required by the PKP2B holder, PT Adaro Indonesia. This condition reflects a gap between policy formulation and implementation across various SMKP elements. This study employed a qualitative approach using open coding, axial coding, and selective coding techniques to identify the root causes of non-compliance in SMKP implementation. Data were collected through document reviews, interviews, field observations, and focus group discussions (FGDs) conducted in three operational areas involving eight key informants. The open coding results reveal that the main obstacles include policies that remain merely as documents without being translated into actionable programs, unmeasurable planning, mismatches in personnel competencies, operational implementation that does not comply with procedures, and weak evaluation and follow-up mechanisms. Through axial coding, these obstacles were categorized into four main groups: policy weaknesses, ineffective planning, inconsistent implementation, and low evaluation accountability. The core theme identified through selective coding indicates that the lack of integration of a safety culture within organizational governance is the primary factor contributing to the gap between policy and SMKP implementation. This study emphasizes the need to reformulate SMKP implementation, strengthen organizational safety structures, and optimize monitoring and evaluation systems to enhance compliance of mining service companies with applicable safety standards and regulations.

Abstract

This paper investigates the urgent need to reconstruct the principle of proportionality within contracts for palm oil partnerships, where structural power imbalances, information asymmetry, opaque financing arrangements, and unilateral sanction mechanisms systematically disadvantage plasma smallholders. The study aims to identify the fundamental factors that hinder the effective application of proportionality in oil palm partnership and to formulate an operational framework capable of ensuring contractual justice within highly asymmetric agribusiness relationships. Employing a normative juridical method complemented by conceptual, comparative, and socio-legal approaches, this research analyses Indonesian contract law, institutional practices, and international regulatory models drawn from Malaysia, Thailand, and India. The findings reveal that the proportionality principle in Indonesia remains largely abstract and lacks enforceable parameters, enabling exploitative contractual clauses such as undisclosed deductions, disproportionate risk distribution, and one-sided penalties to persist in nucleus plasma schemes. Comparative insights demonstrate that proportionality can be translated into practice through mandatory disclosure obligations, standardized minimum clauses, equitable risk-sharing mechanisms, contract registration, and accessible local dispute-resolution systems. The principal novelty of this study lies in proposing a three-pillar operational model of proportionality substantive, procedural, and sanction-based integrated with institutional governance reforms and community empowerment strategies. The paper concludes that reconstructing proportionality requires both normative refinement and structural intervention across negotiation processes, corporate procurement practices, evidentiary mechanisms, and state oversight. This integrated framework provides a concrete basis for embedding substantive justice within palm oil agreements and strengthening legal protection for structurally weaker parties.

Abstract

Plantation partnerships constitute one of the instruments for community empowerment, juridically grounded in Law Number 39 of 2014 concerning Plantations as well as the contractual provisions set forth in the Civil Code. However, in practice, the implementation of partnership agreements frequently gives rise to various legal, economic, and social issues. This article examines and analyzes the implementation of the Oil Palm Plantation Partnership Cooperation Agreement between the core company and plasma farmers in Kuala Dasal Village, Tanjung Jabung Barat Regency, Jambi Province.This research employs an empirical juridical method with a descriptive qualitative approach. The findings indicate that in its implementation there remains an imbalance in bargaining power between the company and the farmers, a lack of transparency in financial management and profit-sharing mechanisms, and limited understanding among farmers regarding the substance of the contract. Based on these findings, this article advocates for the reconstruction of oil palm plantation partnership agreements. Furthermore, it elaborates on the concept of an ideal oil palm plantation management agreement.
