Abstract

This study evaluates the growth performance and cost-effectiveness of six different seedling media for tomato (Lycopersicum esculentum Mill) cultivation: sand (M1), rice husk charcoal (M2), clay (M3), organic fertilizer (M4), clay-organic fertilizer (M5), and sand-organic fertilizer (M6). The experiment assessed plant height, number of leaves, and number of branches from 7 to 35 days after sowing (DAS). Results showed that media containing organic fertilizer (M4, M5, M6) significantly enhanced all growth parameters compared to non-organic treatments. Among these, M5 (clay-organic fertilizer) achieved the highest values for plant height (34.9 cm), number of leaves (15.5), and number of branches (5.5) at 35 DAS, indicating superior performance. However, cost analysis revealed that M5 also incurred the highest production cost. In contrast, M6 (sand-organic fertilizer) offered a more cost-effective option by providing strong growth performance at a lower cost. These findings highlight the importance of incorporating organic fertilizers into seedling media to improve early growth stages of tomato plants. The use of organic blends, particularly M6, presents a practical and sustainable solution for smallholder farmers aiming to maximize seedling vigor without incurring high input costs, ultimately supporting more efficient and eco-friendly agricultural practices.

Abstract

Plastic waste represents a significant global environmental challenge due to its resistance to natural degradation and its widespread pollution impact. In Indonesia, the management of household plastic waste remains inadequate, largely due to limited public awareness and engagement. To address this issue, a community-based initiative was developed to build local capacity for managing plastic waste by creatively repurposing used water gallons into functional trash bins. This approach involved direct, hands-on training and ongoing mentoring of residents in Bangi, Woromarto Village, Purwoasri District, Kediri Regency. The effectiveness of the program was evaluated through participatory observation and systematic documentation of the products created by community members. The findings revealed a significant increase in community participation in recycling activities and the strategic placement of the repurposed trash bins throughout the village, thereby improving local waste management practices. Beyond providing a practical solution for reducing plastic waste accumulation, this initiative fostered positive behavioral changes by encouraging residents to adopt more responsible and sustainable practices centered on environmental stewardship and maximizing the value of discarded materials. Permasalahan sampah plastik merupakan isu global yang memberikan dampak serius terhadap pencemaran lingkungan karena sifat plastik yang sangat sulit terurai secara alami. Di Indonesia, pengelolaan sampah rumah tangga terutama plastik, masih belum optimal akibat rendahnya tingkat kesadaran dan partisipasi masyarakat dalam mengelola limbah tersebut. Untuk mengatasi permasalahan ini, kegiatan yang dilaksanakan bertujuan untuk meningkatkan kapasitas masyarakat dalam pengelolaan sampah plastik melalui pemanfaatan galon bekas sebagai bahan utama pembuatan tempat sampah. Pendekatan yang digunakan adalah metode partisipatif melalui pelatihan dan pendampingan langsung kepada warga Dusun Bangi, Desa Woromarto, Kecamatan Purwoasri, Kabupaten Kediri. Evaluasi keberhasilan kegiatan dilakukan dengan observasi partisipatif dan dokumentasi hasil karya warga. Hasil kegiatan menunjukkan peningkatan keterlibatan masyarakat dalam proses daur ulang serta tersebarnya tempat sampah hasil olahan di berbagai titik desa. Kegiatan ini tidak hanya memberikan solusi praktis dalam pengurangan sampah plastik, tetapi memicu perubahan perilaku masyarakat menuju pengelolaan lingkungan yang lebih bertanggung jawab, berkelanjutan, dan bernilai guna.
