“…Strategi yang banyak diterapkan oleh petani bawang merah dalam melakukan pemeliharaan dan penanggulangan hama penyakit adalah dengan memberikan pupuk sintetis dan pestisida nonorganik. Salah satu dampak penggunaan bahan sintetis yang berlebihan mengakibatkan biaya produksi naik dan ekosistem tanah terganggu, seperti penurunan sifat biokimia tanah, polusi lingkungan, dan kontaminasi hasil pertanian (Antonius et al 2021). Perubahan sifat fisik dapat dilihat dari struktur tanah yang keras dan sulit diolah.…”

“…Kesuburan tanah berkaitan erat dengan kelimpahan dan keragaman mikrob yang berperan penting dalam meningkatkan pertumbuhan dan produktivitas bawang merah. Pengayaan bahan organik, seperti kompos, ke dalam tanah mampu meningkatkan komunitas dan aktivitas mikroorganisme tanah yang berkontribusi dalam perbaikan kesehatan tanah dan produktivitas tanaman (Antonius et al 2021). Kompos dilaporkan dapat meningkatkan pertumbuhan dan hasil bawang merah pada berbagai kondisi tanah karena mampu menyediakan lebih banyak unsur hara pada umbi tanaman bawang merah (Sopha, 2020).…”

Shallot productivity relies on diverse environmental conditions, including soil fertility. Compost is an organic material that is crucial for the improvement of soil health and fertility. Compost amendment could be employed on shallot to improve its growth and productivity. This study aims to investigate the effect of 4 different composts amendments, processed with 4 different bioactivators, on the shallot growth (Bima–Brebes variety), the dynamic of culturable microbes, and nutrient content on the growth medium inside the polybag. Treatments include a mature compost processed with no biactivators (K0), and with the bioactivator Bioaktimo (K1), Beyonic Startmik (K2), indigenous (K3), and the mixed of K1, K2, and K3 (K4). Measured parameters on shallot growth include plant height, number of leaves, stem diameter, wet and dry weights of shallot bulb, root, and above-ground biomass, and chlorophyll content. In addition, physical, chemical, and biological characteristics of the initial planting medium on the polybag were determined. The result showed that compost amendment significantly increased all parameters tested, except chlorophyll content, when compared to the control and the treatment with 100% chemical fertilizer. The best shallot growth was found in the treatment with soil planting media of 75% Soil + 25% Compost K4 (TK5). Keywords: organic fertilizer, bioactivator, shallot
