Abstract

Applying environmentally friendly technology in melon cultivation aims to create sustainable agriculture. Nutrient and plant growth regulators management are simple to apply and have a relatively rapid effect on melon fruit production. Water footprint assessment in melon cultivation is crucial for ensuring sustainable agricultural practices and efficient water use. This study aimed to evaluate the electroconductivity of nutrient solutions and GA3 concentration in increasing fruit production and water footprint efficiency. This research was conducted from June to September 2022 at Tefa SGH Polije. This research used a completely randomized design with treatments that consisted of nine combinations of nutrient solution electrical conductivities (2.8, 3.2, and 3.6 mS cm-1) and GA3 concentrations (0, 60, and 120 mg L-1). Observation variables were fruit diameter, edible part thickness, fruit sweetness level, fruit weight, and water footprint. Data were analyzed using ANOVA and DMRT. Applying 2.8 mS cm-1 nutrient solution (NS) + 60 mg L-1 GA3 was the best treatment according to fruit diameter, edible part thickness, and fruit sweetness level. Although statistically, it had no significant effect, 2.8 mS cm-1 NS + 60 mg L-1 GA3 increased fruit weight by 18.75% and water footprint efficiency by 15.48% compared to control.

Abstract

Eggplant (Solanum melongena L.) is an important horticultural crop in tropical and subtropical regions. However, suboptimal seed germination and poor early seedling growth often impede successful crop establishment. Seed priming with potassium nitrate (KNO₃) is widely recognized for enhancing seed performance, but prolonged soaking in priming solutions can limit oxygen availability during imbibition, potentially inhibiting metabolic activity and reducing priming efficiency. This study aimed to evaluate the effectiveness of aerated KNO₃ priming in improving germination and seedling vigor of eggplant. A completely randomized design with seven treatments, including control, KNO₃ concentrations (0%, 1%, 2%), and priming conditions (with and without aeration), was applied. Results showed that seed priming significantly improved germination parameters, stem diameter, and dry mass. The best germination performance was observed in seeds primed with 2% KNO₃ under aeration with 88.50% germination, the highest germination rate index (23.08), and the shortest mean germination time (3.38 days). While priming did not significantly affect plant height at 35 days after planting, and the concentration of KNO₃ did not significantly affect the seedling performances, aeration significantly increased stem diameter and seedling dry mass. These findings suggest that aerated priming with 2% KNO₃ can be recommended as an effective technique to enhance germination performance and seedling vigor in eggplant.

Abstract

Permasalahan ketersediaan dan tingginya harga pupuk menjadi tantangan utama bagi banyak petani, termasuk di Desa Seputih, Kecamatan Mayang, Kabupaten Jember. Biaya operasional budidaya yang tidak sebanding dengan hasil produksi menjadi kendala serius dalam meningkatkan produktivitas pertanian. Melalui pendekatan konsep zero waste, pemanfaatan potensi limbah hasil pertanian diharapkan dapat menjadi solusi yang efektif untuk mengatasi persoalan ini. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan wawasan dan keterampilan petani dalam mengolah limbah produksi benih dan kotoran ternak menjadi pupuk organik yang lebih bernilai guna dan bernilai ekonomi. Metode pelaksanaan kegiatan meliputi survei potensi desa, sosialisasi manfaat pupuk organik, pelatihan pembuatan pupuk organik padat dan cair, serta evaluasi menggunakan kuesioner. Hasil evaluasi menunjukkan peningkatan signifikan dalam pengetahuan dan keterampilan petani setelah mengikuti kegiatan ini. Hal ini ditunjukkan dengan 40% petani telah mulai mencoba memproduksi pupuk organik secara mandiri. Diharapkan, kegiatan ini dapat mendorong keberlanjutan praktik pengolahan limbah di tingkat petani, sehingga mereka tidak hanya mampu memenuhi kebutuhan pupuk sendiri, tetapi juga mendukung produksi benih hortikultura yang ramah lingkungan dan bebas limbah.
