Abstract

Permasalahan dalam penelitian ini adalah rendahnya hasil belajar siswa pada mata pelajaran Biologi kelas XI IPA SMAS 2 Diponegoro Wuluhan. Guru mata pelajaran tersebut menerapkan model pembelajaran Problem Based Learning (PBL) dengan bergantung pada Lembar Kerja Siswa (LKS), namun hasil yang diperoleh masih belum optimal. Dalam hal ini, didapati bahwa ketergantungan pada LKS secara monoton cenderung menimbulkan rasa jenuh pada diri siswa saat proses belajar. Kondisi tersebut dipicu oleh ketidaktepatan pemilihan model pembelajaran, di mana model yang digunakan cenderung membosankan sehingga hasil capaian belajar peserta didik kurang optimal. Melalui demikian, penelitian ini ditujukan sebagai salah satu upaya optimalisasi mencapai hasil belajar yang tinggi oleh siswa dengan mengetahui laju kenaikan hasil belajar Biologi oleh siswa kelas XI IPA SMAS 2 Diponegoro Wuluhan jika menerapkan Model PBL Berbantuan Wordwall. Penelitian ini termasuk ke dalam tindakan kelas, di mana pelaksanaannya terjadi selama dua siklus dengan masing-masing dua kali pertemuan. Hasilnya terungkap bahwa terdapat kenaikan hasil belajar siswa, yang semula pada siklus I nilai ketuntasannya hanya sebesar 50%, kini pada siklus II mencapai 85%. Maka, didapati jika hasil capaian belajar siswa meningkat sebesar 35%.

Abstract

This study aims to design and assess the technical, environmental, and economic feasibility of an integrated Zero-Waste Palm Oil biorefinery for the production of Sustainable Aviation Fuel (SAF) and other value-added co-products. A quantitative-descriptive approach was employed, integrating process simulation using Aspen Plus V14, Life Cycle Assessment (LCA), and financial modeling to evaluate the system’s performance and sustainability. Primary data were obtained from operational palm oil mills. In contrast, secondary data were sourced from the International Energy Agency (IEA), the International Renewable Energy Agency (IRENA), Statistics Indonesia (BPS), and the Ministry of Energy and Mineral Resources (ESDM) during 2023–2024. The results demonstrate that the integrated biorefinery configuration, which combines thermochemical conversion pathways (pyrolysis, gasification, and Fischer–Tropsch synthesis) with biochemical processes (anaerobic digestion), achieves a mass conversion efficiency of 58.4 percent, net energy efficiency of 72 percent, and an Energy Return on Investment (EROI) of 4.97, exceeding the global bioenergy feasibility threshold of three. The LCA results indicate total Life-cycle emissions of 17.3 g CO?-eq per MJ, representing an 80.6 percent reduction relative to fossil-based Jet A-1 fuel, thereby meeting both CORSIA and RED II sustainability standards. The system also achieves a 95 percent reduction in solid residues, effectively realizing a near-zero-waste operation. Financial modeling reveals a net present value (NPV) of USD 68.2 million, an internal rate of return (IRR) of 17.6 percent, and a payback period of 6.2 years, confirming the project’s economic viability. Overall, this model establishes a scalable pathway for decarbonizing the palm oil industry through circular bioeconomy principles and positions Indonesia as a potential global hub for SAF production aligned with international carbon reduction targets.

Abstract

The European Union (EU) introduced the Carbon Border Adjustment Mechanism (CBAM) to impose carbon price on imported goods based on their carbon footprint, aiming to mitigate carbon leakage and accelerate global decarbonization. While designed to promote sustainable industrial practices, CBAM poses significant challenges for emerging markets and developing economies (EMDEs), including Indonesia, which depends heavily on carbon-intensive industries for export revenues. This study investigates CBAM’s potential impact on Indonesia’s trade competitiveness, economic stability, and policy landscape by comparing its projected consequences in Indonesia with its implementation in the EU. This research employs a qualitative approach through a literature review, analyzing academic studies, policy reports from organizations such as the OECD, WTO, and IMF, and case studies from Indonesia and EU member states. The findings reveal that implementing CBAM in Indonesia would elevate production costs, weaken export competitiveness, and heighten economic risks for industries reliant on high-emission production, particularly in the manufacturing and energy sectors. Moreover, CBAM could intensify social challenges, including job losses and inflationary pressures. However, a comparative analysis with the EU’s experience highlights potential opportunities for Indonesia, such as incentives for a green economic transition, increased investment in renewable energy, and alignment with global sustainability standards. These findings underscore the urgency for Indonesia to formulate strategic policy responses, including trade diversification, technological innovation, and active participation in international climate negotiations. By providing a comparative perspective, this study advances the discourse on climate and trade policies, emphasizing the need for an equitable and adaptive regulatory framework that enables developing economies to navigate the global transition toward sustainability.

Abstract

Background: This research addresses regulatory friction and systemic risks arising from the integration of tokenised bullion into the Decentralised Finance (DeFi) ecosystem, focusing on how to balance investor protection with continued innovation. It outlines the context of DeFi’s permissionless architecture, the sensitivity of bullion as a high value asset class, and the resulting challenges for regulatory certainty and market integrity. Methods: The study employs an analytical and conceptual approach based on a comprehensive literature review and the examination of international regulatory frameworks, including IOSCO principles and FATF recommendations. It develops an adaptive regulatory model by comparing existing rules on securities, commodities, and virtual assets with the specific risk profile of tokenised bullion in DeFi. Findings: The analysis identifies core conflicts between DeFi’s borderless, permissionless protocols and jurisdiction bound AML/KYC requirements, as well as single point of failure risks arising from custodial bullion structures. To address these conflicts, the paper proposes a DeFi Bullion Specific Regulatory Sandbox Framework grounded in technology neutral and risk based principles, which embeds regulatory KPIs, capital adequacy thresholds, and RegTech enabled real time monitoring. Conclusion: The results indicate that the proposed sandbox model offers a viable pathway to mitigate systemic risk and enhance regulatory certainty by enforcing compliance at critical on chain and off chain interaction points, particularly physical redemption of bullion. The framework strengthens investor protection while preserving space for innovation in tokenised bullion markets. Novelty/Originality of this article: This research delivers a comprehensive and actionable regulatory blueprint tailored to tokenised bullion in DeFi, explicitly addressing jurisdictional arbitrage and dual asset integrity issues. Its original contributions include defining technical prerequisites for embedding AML compliance into DAO governance and outlining a cross border mandatory liquidation protocol as a theoretical roadmap for regulators and industry stakeholders.
