Abstract

The use of several shallot varieties applied with the biological agent Bacillus spp. is one of the most developed methods of controlling twisted disease, as it is safe and efficient. The large number of shallot varieties released to farmers requires the selection of varieties with the best resistance response to twisted disease. This study aimed to determine the different responses between five local shallot varieties treated with a combination of Bacillus velezensis B-27 and B. cereus RC76 against the twisted disease. This study was conducted in a greenhouse and on the field using Tajuk, Bima Brebes, Bauji, Crok Kuning, and Manjung varieties, which were dipped and sprayed with a B. velezensis B-27 and B. cereus RC76. The treatment of B. velezensis B-27 and B. cereus RC76 on five varieties showed a good response to suppressing twisted disease. The twisted disease incubation period in five varieties treated with the combination of B. velezensis B-27 and B. cereus RC76 showed a slower result than the control, the disease incidence and intensity could be reduced by 70 90%. The best resistance response of varieties treated with the combination of B. velezensis B-27 and B. cereus RC76 was shown by Tajuk compared to the other four varieties.

Abstract

Kegiatan pengabdian kepada masyarakat mengenai budidaya agroforestry kopi Liberika di bawah tegakan kelapa sawit dilaksanakan untuk meningkatkan pengetahuan dan keterampilan petani dalam memanfaatkan ruang gawangan secara produktif dan berkelanjutan. Petani di Desa Temiang masih menghadapi kendala minimnya pengetahuan teknis budidaya kopi, rendahnya pemahaman agroforestry, serta tingginya kejadian penyakit tanaman pada lahan gambut. Kegiatan dilakukan melalui ceramah interaktif, diskusi kelompok, demonstrasi lapangan, praktik langsung, serta pembahasan studi kasus. Hasil kegiatan menunjukkan peningkatan signifikan pada pemahaman petani terkait teknik budidaya kopi Liberika, identifikasi penyakit, pemangkasan, sanitasi kebun, serta penerapan pengendalian hama terpadu. Peserta juga mampu menganalisis masalah lapangan secara lebih tepat dan menunjukkan motivasi lebih tinggi untuk menerapkan tumpang sari kopi–sawit. Dampak kegiatan meliputi peningkatan kapasitas teknis, kesiapan adopsi inovasi agroforestry, serta peluang penguatan ekonomi melalui diversifikasi komoditas. Secara keseluruhan, kegiatan ini berhasil mendukung pengembangan sistem agroforestri berkelanjutan pada kebun sawit masyarakat.
