Continuous use of agrochemicals can cause heavy metal contamination. This study aimed to investigate chromium removal, physiological characters, and yield of shallot (Allium ascalonicum L.) on biochar and mycorrhizae application on chromium-contaminated soil. A pot experiment was conducted at the screen house ex-farm of the Faculty of Agriculture, Jenderal Soedirman University. The treatments tested consisted of two factors. The first factor was biochar dosage (B) consisting of 4 levels, i.e., B0 = without biochar, B1 = 1.2 g biochar kg-1 of soil, B2 = 2.4 g biochar kg-1 of soil, and B3 = 4.8 g biochar kg-1 of soil. The second factor was mycorrhizae inoculation consisting of 3 levels, i.e., M0 = without mycorrhizae, M1 = 0.1 g mycorrhizae kg-1 of soil, M2= 0.2 g mycorrhizae kg-1 of soil. The twelve treatments were arranged in a randomized block design with three replications. The results showed that the application of 1.2 g, 2.4 g, and 4.8 g biochar kg-1 of soil had been able to increase plant height and the percentage of root infection. The application of mycorrhizae 0.1 g and 0.2 g mycorrhizae kg-1 of soil was able to increase plant height, percentage of root infection, and plant tissue P uptake. Both applications of biochar and mycorrhizae increased plant height and the percentage of root infection by mycorrhizae.

Abstract

Teknologi nano menawarkan potensi besar dalam meningkatkan efisiensi dan keberlanjutan di sektor lingkungan, energi, dan pertanian. Pendekatan sintesis partikel nano berbasis tumbuhan (phytosynthesis) muncul sebagai metode ramah lingkungan yang menggantikan bahan kimia beracun dengan metabolit alami, menghasilkan partikel nano yang stabil, seragam, dan ekonomis. Aplikasi teknologi nano dalam fitoremediasi memanfaatkan kemampuan tanaman hiperakumulator untuk menyerap polutan dan mengubahnya menjadi material bernilai tinggi, sementara dalam bioenergi, partikel nano berperan sebagai katalis yang meningkatkan konversi lignoselulosa menjadi bioetanol serta produksi biogas. Di bidang pertanian, pupuk-nano dan pestisida-nano berbasis logam oksida seperti ZnO dan CuO meningkatkan efisiensi nutrisi dan perlindungan tanaman dari patogen, didukung oleh karbon nanotube (CNTs) yang memperbaiki struktur tanah dan penyerapan air. Namun demikian, tantangan seperti toksisitas partikel nano terhadap lingkungan, bioakumulasi dalam rantai makanan, dan gangguan pada mikroba tanah memerlukan perhatian serius. Selain itu, pendekatan berbasis data seperti kecerdasan buatan (Artificial Intelligence / AI) dan pembelajaran mesin (Machine Learning / ML) menyediakan solusi untuk mengoptimalkan desain partikel nano, meningkatkan stabilitas, dan meminimalkan dampak toksik. Integrasi teknologi nano dengan pendekatan ini diyakini mampu mempercepat inovasi di berbagai sektor sekaligus mendukung keberlanjutan ekosistem secara global.
