Abstract

Ants have a very important role in an ecosystem. The insects act as decomposers, pollinators, soil aerators, pest controllers, and predators. Their role is very varied so that they can be easily found in various ecosystems, one of which is the rubber and oil palm ecosystem. The ant’s diversity in this forest eventually will affect the productivity of the land. The aim of this study is to determine the diversity and role of ants in the rubber and oil palm plantations in Sungai Merah Village. Both of the plantations dominate the industrial forest in Jambi. The method used in this study was purposive random sampling. Observation plots were installed in the ecosystem of rubber and oil palm plantations; each ecosystem had 4 plots consisting of 9 units of pitfall traps, and 9 units of bait traps. The results of this study show that 15 species of ants are found in the ecosystem of rubber and oil palm plantations. Furthermore, the collected ants consisted of 39.972 individual ants belonging to 12 genera and 5 subfamilies. Ants establish in the ecosystem of rubber and oil palm plantations in Sungai Merah Village have an important role either as predators (Crematogaster spp., Odontomachus rixosus, Odontoponera tranversa, Pheidole huberi, Tetraponera rufonigra, Tapinoma melanocephalum, Camponotus spp. and Colobopsis moeschi), or foragers such as ants from the genera Anoplolepis, Camponotus, Monomorium and Polyrhachis. As predators, Oecophylla smaragdina, Camponotus spp. and Crematogaster spp. also play a role as biological control agents in the ecosystem.

Abstract

Background: Cucumber (Cucumis sativus L.) is a vegetable plant from the Cucurbitaceae family whose production in Indonesia has decreased. Water hyacinth can be used as an organic fertilizer, and the application of Local Microorganisms (MOL) has been shown to improve the physical, chemical, and biological properties of the soil. This study aims to determine the effect of water hyacinth bokashi application and stale rice MOL on the growth and yield of cucumber plants and the most effective dose. Methodology: A factorial completely randomized design (CRD) was employed, utilizing 12 treatment combinations, which were repeated three times, resulting in 36 experimental units. The first factor is the Stale Rice MOL Factor (M), consisting of three levels, namely (M0) Control (M1) 100 ml/liter of water, (M2) 150 ml/liter of water. The second factor is Water Hyacinth. th Bokashi (E) with three levels, namely (E0) Control, (E1) 80 g / polybag, (E2) 130 g / polybag, (E3) 180 g / polybag. Findings: The findings indicated that the implementation of water hyacinth bokashi in conjunction with stale rice MOL exerted an influence on plant height parameters at 30 DAP. The optimal dosage of water hyacinth bokashi was determined to be 180 g/polybag in combination with stale rice MOL, equivalent to 150 ml/liter of water. Contribution: These results suggest that the integration of organic matter and local microbial inputs can serve as a sustainable alternative to synthetic fertilizers in cucumber cultivation, contributing to improved soil health and supporting environmentally friendly agricultural practices.
