Abstract

The utilization of non-wood biomass residues as alternative solid fuels is important for supporting low-carbon energy transitions and circular bioenergy development. This study evaluated the quality and energy performance of charcoal briquettes produced from vegetative residues of sugar palm (Arenga pinnata), specifically fronds, fruit stalks, and a mixture of both materials. A completely randomized design was applied, and the briquettes were assessed based on physical properties, proximate composition, combustion performance, and charcoal yield, with SNI 01-6235-2000 used as the primary quality benchmark. The results showed that all briquette types had very low moisture content (1.69–2.03%) and high calorific values (5,427–5,985 cal g⁻¹), meeting the SNI requirements for these parameters. Significant differences among plant parts were observed in ash content, volatile matter, and fixed carbon content (p < 0.05), indicating that raw material characteristics strongly influenced briquette quality. Briquettes produced from sugar palm fronds exhibited the highest fixed carbon content and calorific value, as well as the lowest burning rate, reflecting better thermal stability and longer combustion duration. Meanwhile, briquettes made from the mixture of fronds and fruit stalks showed the lowest ash content and the most balanced quality profile. Although some proximate parameters, particularly volatile matter and fixed carbon, did not fully meet the SNI limits, these limitations are process-dependent and may be improved through optimization of carbonization conditions. Overall, sugar palm vegetative residues represent a promising non-wood biomass resource for sustainable charcoal briquette production within a circular bioenergy framework.

Abstract

Peningkatan tekanan terhadap lahan pertanian, kerusakan lingkungan, dan kebutuhan akan ketahanan pangan mendorong perlunya pengembangan sistem pertanian yang berkelanjutan dan multifungsi. Sistem Pertanian Terpadu Berkelanjutan (SPTB) merupakan pendekatan inovatif yang mengintegrasikan berbagai elemen produksi seperti tanaman pertanian, tanaman kehutanan, peternakan, perikanan, dan kegiatan ekowisata dalam satu kesatuan sistem yang saling mendukung. Artikel ini merancang model SPTB berbasis agroforestri dan ekowisata yang dikembangkan pada lahan seluas 2 hektar dengan mempertimbangkan prinsip-prinsip konservasi, keberlanjutan ekologis, serta pemberdayaan masyarakat lokal. Pendekatan penelitian menggunakan metode deskriptif kualitatif melalui kajian literatur dan analisis konseptual. Agroforestri dirancang sebagai basis produksi dan konservasi yang terdiri dari tanaman keras tahunan dan tanaman pertanian musiman yang dikelola secara ekologis. Sementara itu, ekowisata dikembangkan sebagai sarana edukasi, rekreasi, dan pemberdayaan masyarakat melalui aktivitas seperti forest healing, agropetik, pengelolaan sampah terpadu, dan pendidikan lingkungan. Pembagian ruang kawasan dilakukan dalam tiga zona utama: 30% untuk tanaman kehutanan, 50% untuk tanaman pertanian, dan 20% untuk fasilitas wisata atau amenities. Seluruh aktivitas dirancang dengan pendekatan ramah lingkungan dan minim limbah. Model ini menunjukkan bahwa integrasi agroforestri dan ekowisata dalam kerangka SPTB mampu menciptakan sistem yang produktif, konservatif, dan inklusif, serta mendukung pencapaian tujuan pembangunan berkelanjutan (SDGs), khususnya tujuan 13 (aksi terhadap perubahan iklim) dan tujuan 15 (menjaga ekosistem darat). Desain ini diharapkan dapat direplikasi dalam pengelolaan lahan multifungsi berbasis masyarakat. Kata kunci: sistem pertanian terpadu, agroforestri, ekowisata, keberlanjutan, konservasi, SDGs Integrated Agriculture System Design Abstract Increasing pressure on agricultural land, environmental degradation, and the need for food security are driving the need to develop sustainable and multifunctional agricultural systems. The Sustainable Integrated Farming System (SPTB) is an innovative approach that integrates various production elements such as agricultural crops, forestry crops, livestock, fisheries, and ecotourism activities into a single, mutually supportive system. This article designs an agroforestry and ecotourism-based SPTB model developed on a 2-hectare plot of land, considering the principles of conservation, ecological sustainability, and local community empowerment. The research approach uses qualitative descriptive methods through literature review and conceptual analysis. Agroforestry is designed as a production and conservation base, consisting of perennial and seasonal agricultural crops managed ecologically. Meanwhile, ecotourism is developed as a means of education, recreation, and community empowerment through activities such as forest healing, agropetics, integrated waste management, and environmental education. The area is divided into three main zones: 30% for forestry crops, 50% for agricultural crops, and 20% for tourism facilities or amenities. All activities are designed with an environmentally friendly and waste-free approach. This model demonstrates that integrating agroforestry and ecotourism within the SPTB framework can create a productive, conservative, and inclusive system, and support the achievement of the Sustainable Development Goals (SDGs), particularly Goal 13 (action on climate change) and Goal 15 (protecting terrestrial ecosystems). This design is expected to be replicated in community-based multifunctional land management. Keywords: integrated farming system, agroforestry, ecotourism, sustainability, conservation, SDGs

Abstract

Sistem pangan global saat ini menghadapi tekanan multidimensional yang semakin kompleks akibat interaksi krisis ekologis, sosial, ekonomi, dan politik. Perubahan iklim, degradasi lahan, hilangnya biodiversitas, serta ketimpangan dalam struktur ekonomi pangan telah meningkatkan kerentanan sistem produksi pangan di berbagai wilayah. Dalam konteks tersebut, agroekologi berkembang sebagai pendekatan alternatif yang menekankan integrasi antara prinsip ekologi, keberlanjutan sosial, dan penguatan ekonomi lokal dalam sistem pertanian. Penelitian ini bertujuan untuk menganalisis peran agroekologi dalam transformasi sistem pangan berkelanjutan serta mengkaji relevansinya dengan praktik agraris lokal di Indonesia. Penelitian menggunakan pendekatan systematic literature review (SLR) dengan menganalisis berbagai publikasi ilmiah internasional, laporan lembaga global, serta literatur akademik yang relevan dengan agroekologi dan sistem pangan berkelanjutan. Analisis dilakukan melalui identifikasi tema-tema utama yang mencakup krisis sistem pangan global, prinsip dan kerangka teoretis agroekologi, perkembangan penelitian agroekologi, praktik agraris lokal Indonesia, serta hambatan implementasi agroekologi. Hasil kajian menunjukkan bahwa agroekologi memiliki potensi besar dalam meningkatkan resiliensi agroekosistem melalui diversifikasi produksi, efisiensi pemanfaatan sumber daya, serta penguatan kelembagaan komunitas. Praktik agraris lokal di Indonesia seperti agroforestri, kebun campur, subak, dan mina padi menunjukkan kesesuaian yang kuat dengan prinsip agroekologi dan berpotensi mendukung sistem pangan yang lebih berkelanjutan. Namun implementasi agroekologi secara luas masih menghadapi berbagai hambatan struktural, termasuk dominasi kebijakan pertanian berbasis input eksternal, lemahnya kelembagaan petani, serta keterbatasan akses teknologi dan pasar. Penelitian ini menunjukkan bahwa agroekologi dapat menjadi kerangka konseptual penting dalam mentransformasi sistem pangan menuju model yang lebih resilien, adil, dan berkelanjutan melalui integrasi pengetahuan lokal, inovasi ilmiah, serta kebijakan publik yang inklusif.   Kata kunci: agroekolog; sistem pangan berkelanjutan; transformasi sistem pangan; pertanian berbasis biodiversitas.   ABSTRACT. The global food system is currently facing increasing multidimensional pressures resulting from the interaction of ecological, social, economic, and political crises. Climate change, land degradation, biodiversity loss, and structural inequalities in food distribution have intensified the vulnerability and instability of agricultural production systems worldwide. In this context, agroecology has emerged as an alternative approach that integrates ecological principles, social sustainability, and local economic empowerment in food production systems. This study aims to analyze the role of agroecology in transforming sustainable food systems and to examine its relevance to local agrarian practices in Indonesia. The research employs a systematic literature review (SLR) approach by analyzing international scientific publications, reports from global institutions, and academic literature related to agroecology and sustainable food systems. The analysis identifies key themes including the global food system crisis, theoretical frameworks of agroecology, trends in agroecological research, local agrarian practices in Indonesia, and structural barriers to agroecology implementation. The findings indicate that agroecology has significant potential to enhance agroecosystem resilience through biodiversity-based production systems, efficient resource use, and strengthened community institutions. Traditional agrarian practices in Indonesia—such as agroforestry, mixed gardens, the subak irrigation system, and rice–fish farming—demonstrate strong alignment with agroecological principles and offer important pathways for developing more sustainable food systems. However, the large-scale implementation of agroecology remains constrained by structural barriers, including policy frameworks that prioritize input-intensive agriculture, limited institutional support for smallholder farmers, and restricted access to technology and markets. This study highlights agroecology as a strategic conceptual framework for transforming food systems toward models that are more resilient, equitable, and environmentally sustainable through the integration of local knowledge, scientific innovation, and inclusive public policies.
