Abstract

Yield of green onion has been declining annually in West Kalimantan where land for cultivating green onion is alluvial soil. This study aims to determine the optimal dosage of a combination of areca husk biochar and NPK fertilizer on the growth and yield of green onion plants in alluvial soil. The research was conducted in Sungai Kakap District, Kubu Raya Regency, West Kalimantan Province, from September to November 2024. A non-factorial Randomized Block Design (RBD) comprised six treatments and four replications: b1 = biochar 2 tons.ha⁻¹ + NPK fertilizer 90% (270 kg.ha⁻¹), b2 = biochar 4 tons.ha⁻¹ + NPK fertilizer 80% (240 kg.ha⁻¹), b3 = biochar 6 tons.ha⁻¹ + NPK fertilizer 70% (210 kg.ha⁻¹), b4 = biochar 8 tons.ha⁻¹ + NPK fertilizer 60% (180 kg.ha⁻¹), b5 = biochar 10 tons.ha⁻¹ + NPK fertilizer 50% (150 kg.ha⁻¹), and b6 = biochar 12 tons.ha⁻¹ + NPK fertilizer 40% (120 kg.ha⁻¹). The observed variables included plant height, number of leaves, number of tillers, fresh weight, root volume, and dry weight. Data obtained from observations were analyzed using Analysis of Variance (ANOVA). If significant differences were found, a DMRT test at a 5% significance level was conducted to determine differences among treatments after obtaining the coefficient of variation (KK). The results showed that the treatment of biochar 10 tons.ha⁻¹ + NPK fertilizer 50% (150 kg.ha⁻¹) was the best dosage, significantly affecting plant height, number of leaves, number of tillers, fresh weight, root volume, and dry weight. Further research is recommended using different doses of areca husk biochar and NPK fertilizer, as well as incorporating additional factors, to evaluate their effects on the growth and yield of green onion plants in different soil types.

Abstract

The horn beetle (Oryctes rhinoceros) is an important pest in oil palm plants. This pest damages young leaves that have not yet opened as well as young plants less than two years old and damages the growing point so that the oil palm plant will die. O. rhinoceros can attack young and mature plants and has an inverted V shape. So it is necessary to control O. rhinoceros larvae. The fungus Metarhizium spp. is an entomopathogenic fungus that is used as a bioinsecticide. Utilization of the fungus Metarhizium spp. It is hoped that it will be able to suppress the population of O. rhinoceros larvae in the long term. The methods used in this research were preparation of O. rhinoceros larvae, preparation of the fungus Metarhizium spp., propagation of Metarhizium spp. in rice media, calculation of conidia density of Metarhizium spp., production of biopesticide by encapsulating Metarhizium spp. using coacervation techniques, application of biopesticides, observation and data analysis. Administration of M. anisopliae bio encapsulant to 2nd and 3rd instar O. rhinoceros larvae at a concentration of 108 conidia/ml. This can be seen from the mortality percentage of 52% for O. rhinoceros larvae. M. anisopliae infection showed symptoms of death after the second day of M. anisopliae bio encapsulant application until greenish sporulation spots appeared that covered almost the entire body of O. rhinoceros larvae. Metarhizium spp. isolate. proven to have potential for use as a biological agent because it has high virulence against O. rhinoceros. Key words: bio encapsulant, Metarhizium anisopliae, Oryctes rhinoceros  INTISARIHama kumbang tanduk (Oryctes rhinoceros) sebagai hama penting pada tanaman kelapa sawit. Hama tersebut merusak daun muda yang belum terbuka serta pada tanaman yang masih muda dengan umur kurang dari dua tahun dan merusak titik tumbuh sehingga tanaman kelapa sawit akan mati. O. rhinoceros dapat menyerang tanaman yang masih muda maupun yang dewasa serta berbentuk huruf V terbalik. Sehingga diperlukan pengendalian terhadap larva O. rhinoceros. Cendawan Metarhizium spp. merupakan cendawan entomopatogen yang dimanfaatkan sebagai bioinsektisida. Pemanfaatan cendawan Metarhizium spp. diharapkan mampu menekan populasi larva O. rhinoceros dalam jangka panjang.  Metode yang digunakan dalam penelitian ini yaitu persiapan larva O. rhinoceros, persiapan cendawan Metarhizium spp., perbanyakan Metarhizium spp.di media beras, perhitungan kerapatan konidia Metarhizium spp., pembuatan biopestisida dengan enkapsulasi Metarhizium spp. menggunakan teknik coacervation, pengaplikasian biopestisida, pengamatan, serta analisis data.
