Abstract

Desa Klungkung, Kecamatan Sukorambi, Kabupaten Jember merupakan salah satu sentra kopi rakyat yang menghasilkan limbah kulit kopi cukup melimpah. Selama ini, limbah hanya dibuang atau dibakar sehingga menimbulkan pencemaran lingkungan. Kegiatan pengabdian ini bertujuan untuk meningkatkan keterampilan petani dalam mengolah limbah kulit kopi basah maupun kering menjadi pupuk organik cair (POC) bernilai tambah, serta mendorong keberlanjutan usaha tani kopi yang ramah lingkungan. Kegiatan dilaksanakan pada Mei – Desember 2025 dengan melibatkan 20 anggota Kelompok Tani Hutan (KTH) Santoso Lestrai. Metode pelaksanaan meliputi sosialisasi, pelatihan, dan pendampingan dalam proses produksi POC. Bahan pendukung yang digunakan dalam fermentasi antara lain mikroba starter, molase, dedak, kentang, dan serbuk telur. Hasil kegiatan menunjukkan peningkatan pengetahuan dan keterampilan peserta hingga 100%, dari kondisi awal yang belum mengenal Teknik pengolahan limbah kulit kopi menjadi POC. Produk POC yang dihasilkan mulai diaplikasikan pada lahan pertanian kopi dan tanaman hortikultura anggota kelompok. Dampak kegiatan ini terlihat pada aspek lingkungan (berkurangnya limbah kopi yang terbuang), ekonomi (efisiensi biaya pemupukan), serta sosial (peningkatan keterampilan dan partisipasi petani).

Abstract

Genetic purity in hybrid maize is essential to ensure the stable combination of parental genetic materials, which underpins heterosis and on-field hybrid performance. Conventional field-based tests for assessing hybrid purity are labor-intensive, time-consuming, and less efficient compared to molecular marker-based approaches. Alternatively, DNA-based markers such as simple sequence repeats (SSRs) provide a feasible alternative. DNA-based markers assay requires the DNA extraction method that produces sufficient amount and quality of DNA. Therefore, this study compared three extraction methods—SDS-based, CTAB-based, and a commercial DNA extraction kit—using leaf tissue from maize seedlings as the DNA source. The extracted DNA samples were assessed for yield, quality, and suitability for SSR-based polymerase chain reaction (PCR) assays. Results demonstrated that all three methods successfully produced DNA of adequate quality and quantity for SSR-PCR analysis. These findings confirm the applicability of multiple extraction techniques for molecular based hybrid purity testing. The study contributes practical guidance for optimizing DNA extraction in maize, supporting the broader adoption of molecular markers in hybrid breeding programs.

Abstract

This study investigates innovation ecosystems within Teaching Factory Agribusiness, addressing the critical gap in the literature regarding the absence of a strategic framework to enhance innovation and sustainability in agribusiness education. Using a grounded theory methodology, we conducted in-depth interviews with 20–30 participants, including educators, industry stakeholders, and policymakers, to gain insights into collaboration, resource sharing, and continuous learning dynamics. The results clarify four thematic areas; (1) Collaboration and Partnerships, (2) Resource Mobilization and Sharing, (3) Policy and Institutional Support, and (4) Continuous Learning and Adaptation. The above threads weave together into a framework to make agribusiness education explicit in the functioning of innovation ecosystems. The findings have significance for policy-makers, educationists, and industry personnel involved in improving the quality of agribusiness innovation. Future research directions can be a framework, especially regarding the benefits of innovation, and collaboration through technological facilities.

Abstract

Red chili is a crucial horticultural crop in Indonesia. The increasing demand for high-quality chili necessitates seeds with optimal germination and growth. Spirulina platensis, a microalgae species, can be cultivated in waste media such as Sugar Mill Effluent (SME). Moreover, Spirulina contains phytohormones that can stimulate seed germination. This study investigated the impact of various concentrations and soaking times of S. platensis solution on red chili seed quality. A factorial Completely Randomized Design (CRD) was employed with 5 levels of microalgae biomass concentration: control (untreated seeds), 0, 30, 45, and 60% and 3 levels of soaking time: 1, 2, and 3 hours. Data analysis involved ANOVA and Bonferroni post-hoc tests at a 5% level using GraphPad Prism version 5.01. The results demonstrated seed priming application using S. platensis significantly enhanced seed vigor. The S. platensis treatment at 60% concentration for 2 hours significantly reduced MGT by 1 day, while 30%-2 hours and 60%-3 hours treatments exhibited the highest germination rate (100%), vigor index (49.17% in 30%-2 hours), seed growth simultaneity (85.56% in 60%-2 hours and 83.33% in 30%-2 hours), and growth rate (11.48% in 60%-3 hours and 11.11% in 30%-2 hours), with the 60%-3 hours treatment showing the longest shoot (2.73 cm) and radicle (8.13 cm) lengths, compared to the control. These findings suggest that S. platensis priming can be a promising approach for improving seed quality and crop establishment.
