Abstract

Food security is one of the key strategic issues in sustainable development, particularly at the local community level, which is vulnerable to food crises and climate change. To address this challenge, this community service activity was conducted with the aim of improving knowledge and skills among community members, especially local farmer groups in cultivating herbal plants as a strategy for local food resilience and the implementation of a circular economy at Kebun Dakwah Muhammadiyah Yogyakarta. The cultivated commodities include ginger, aromatic ginger (kencur), turmeric, temulawak, and lemongrass, all of which have high potential as raw materials for value-added herbal products. The educational program was designed using a participatory approach, involving lectures, hands-on training, and mentoring by a multidisciplinary team of lecturers and students from Universitas Ahmad Dahlan’s KKN (Community Service Program). The training covered land preparation, seed selection, eco-friendly cultivation techniques, and post-harvest product processing education to support the circular economy concept. Evaluation results showed a significant increase in participants’ understanding of the benefits of herbal plants (increasing 29%) and cultivation techniques (increasing 30%). This initiative also supports the optimization of existing post-harvest technologies such as solar dryers, while strengthening the circular economy ecosystem in the area. Abstrak. Ketahanan pangan merupakan salah satu isu strategis dalam pembangunan berkelanjutan, khususnya di tingkat komunitas lokal yang rentan terhadap krisis pangan dan perubahan iklim. Untuk menjawab tantangan ini, kegiatan pengabdian kepada masyarakat ini dilaksanakan dengan tujuan meningkatkan pengetahuan dan keterampilan masyarakat khususnya kelompok petani komunitas dalam membudidayakan tanaman herbal sebagai bagian dari strategi ketahanan pangan lokal dan implementasi ekonomi sirkular di Kebun Dakwah Muhammadiyah Yogyakarta. Komoditas yang dibudidayakan meliputi jahe, kencur, kunyit, temulawak, dan sereh wangi yang memiliki potensi tinggi sebagai bahan baku produk olahan herbal bernilai tambah. Program edukasi dirancang melalui pendekatan partisipatif dengan metode penyuluhan, pelatihan praktik langsung, dan pendampingan oleh tim dosen lintas disiplin dan mahasiswa Kuliah Kerja Nyata (KKN) Universitas Ahmad Dahlan. Edukasi dilakukan mulai dari penyiapan lahan, pemilihan bibit, teknik budidaya ramah lingkungan, hingga edukasi pengolahan produk pascapanen sebagai implementasi konsep ekonomi sirkular. Hasil evaluasi menunjukkan adanya peningkatan signifikan dalam pemahaman peserta terhadap manfaat tanaman herbal sebanyak 29% dan teknik budidayanya sebesar 30%. Kegiatan ini juga mendukung optimalisasi teknologi fasilitas pascapanen yang telah ada di lokasi pengabdian seperti rumah pengering, sekaligus memperkuat ekosistem ekonomi sirkular di kawasan tersebut.

Abstract

Urban household waste management in developing countries faces increasing complexity due to population growth, land constraints, and socio-environmental considerations. This study proposes a comparative evaluation of the Analytic Hierarchy Process (AHP) and Fuzzy AHP to support decision-making in selecting sustainable household waste treatment alternatives in Umbulharjo Sub-district, Yogyakarta City, Indonesia. Five sustainability criteria and five alternative treatment methods were identified through expert consultation and literature review. Primary data were collected from 20 household respondents using structured questionnaires. The AHP method applied a crisp pairwise comparison scale, while Fuzzy AHP incorporated linguistic assessments converted into Triangular Fuzzy Numbers to better handle uncertainty and subjectivity. The results demonstrate that while AHP prioritizes the burning method due to perceived simplicity and feasibility, Fuzzy AHP reveals a stronger preference for “Sorting, Hoarding, and Selling,” reflecting the community’s implicit environmental and economic concerns. The divergence in outcomes highlights the limitations of deterministic assessments in complex socio-technical systems and underscores the added value of fuzzy logic in capturing nuanced stakeholder preferences. By integrating quantitative and qualitative criteria within a hierarchical decision framework, this study contributes to the development of more context-sensitive and adaptive decision-support tools. The findings offer practical guidance for municipal authorities and urban planners seeking to align waste management strategies with cleaner production principles. The proposed methodological framework enhances transparency, inclusiveness, and responsiveness in sustainability assessments, supporting the transition toward more resilient and community-driven urban waste systems.
