Abstract

Penurunan produktivitas cabai di Provinsi Gorontalo dalam beberapa tahun terakhir dipengaruhi oleh serangan penyakit layu Fusarium yang disebabkan oleh Fusarium oxysporum, patogen tular tanah yang dapat menurunkan hasil hingga 50%. Pengendalian penyakit ini umumnya masih mengandalkan fungisida sintetis yang berisiko menimbulkan resistensi patogen dan dampak lingkungan. Penelitian ini bertujuan mengevaluasi potensi limbah pertanian, yaitu ekstrak kulit kopi dan kulit singkong, sebagai media perbanyakan Trichoderma brevicompactum serta efektivitasnya sebagai pemacu pertumbuhan dan pelindung benih cabai terhadap infeksi F. oxysporum. Penelitian disusun menggunakan Rancangan Acak Lengkap (RAL) dengan tujuh perlakuan dan tiga ulangan, mencakup kontrol, infeksi patogen, perlakuan fungisida, serta biopestisida berbasis ekstrak limbah pertanian.Hasil penelitian menunjukkan bahwa F. oxysporum menurunkan daya berkecambah dan indeks vigor secara signifikan, dengan nilai terendah pada perlakuan P1 (30% dan 0%). Sebaliknya, perlakuan fungisida (P2) dan biopestisida T. brevicompactum (P3–P6) mampu mempertahankan daya berkecambah tinggi (93,33–96,67%). Indeks vigor tertinggi setelah kontrol ditunjukkan oleh perlakuan ekstrak kulit singkong + F. oxysporum (P6) sebesar 93,33%, mengindikasikan adanya sinergi antara T. brevicompactum dan senyawa bioaktif kulit singkong dalam menekan patogen. Secara keseluruhan, ekstrak limbah pertanian terutama kulit singkong berpotensi sebagai media perbanyakan T. brevicompactum sekaligus sebagai biopestisida hayati ramah lingkungan untuk meningkatkan viabilitas benih cabai dan mendukung pertanian berkelanjutan.

Abstract

 Trichoderma brevicompactum indigenous to Gorontalo is a potential biological control agent that plays an important role in plant disease management and agricultural waste utilization. The availability of cost-effective and environmentally friendly growth media is a key factor in supporting the production of fungal inoculum. This study aimed to describe the growth response of Gorontalo indigenous T. brevicompactum on agricultural waste-based media, namely cassava peel extract and coffee peel extract, in comparison with Potato Dextrose Broth (PDB) as a control medium. The study was conducted using a descriptive approach at the Laboratory of Plant Pests and Diseases, Faculty of Agriculture, Universitas Negeri Gorontalo. The observed parameters included changes in the physical properties of the media (temperature, pH, and color), mycelial biomass, relative growth rate (RGR), absolute growth rate (AGR), and conidial density during the incubation period. The results showed that, descriptively, cassava peel extract exhibited a higher tendency in RGR and AGR values than the control medium and coffee peel extract, particularly during the mid-incubation phase. In contrast, coffee peel extract showed a relatively lower growth response, especially at the later incubation stage. Conidial density increased over time in all media, with the highest values observed in the control medium, followed by cassava peel extract and coffee peel extract. Overall, cassava peel and coffee peel wastes have potential as alternative growth media for T. brevicompactum, with cassava peel extract demonstrating a more favorable growth tendency.

Abstract

This study aims to determine the administration of Trichoderma asperellum TZ11DI1 against Fusarium wilt disease in shallot plants. This study was conducted at the Laboratory of the Agricultural Plant Protection Agency of Gorontalo Province and agricultural land in Hulawa Village, Telaga District, Gorontalo Regency, from February to May 2025. This study used a Completely Randomized Design (CRD) with negative control treatments (T0), Positive control of chemical pesticide application (T1), application of Trichoderma Asperellum TZ11DI1 5 grams (T3), application of Trichoderma Asperellum TZ11DI1 10 grams (T2), and application of Trichoderma Asperellum TZ11DI1 15 grams (T3) each repeated 8 times, so that 40 experimental units were obtained. The variables observed were the incubation period, disease incidence, attack intensity, number of bulbs, and bulb weight. Data analysis used ANOVA and a further LSD test at a significance level of 5%. The results showed that T. asperellum TZ11DI1 treatment was effective in extending the incubation period, reducing disease incidence, and reducing the intensity of Fusarium wilt disease attacks on shallot plants. A higher dose of T. asperellum TZ11DI1 15 grams) significantly reduced the attack rate and produced an average bulb weight of 56.46 g, and the number of bulbs was 18.25 per clump.
