Abstract

Trichoderma spp., is a fungus with the ability to control disease and promote plant growth. The mechanism is through the activity of microparasites, antimicrobial secondary metabolites, phytohormones and mobilization of plant nutrients for plant growth and production. The purpose of this study was to examine the biopolymer composition as a seedcoating formula on corn seeds with Trichoderma as the active ingredient, namely to obtain a biopolymer composition that is able to maintain viability and inactivate Trichoderma during storage. Completely randomized design was used with a single treatment factor for the composition of the formula, i.e.; K1 is control 1 (suspension of conidia Trichoderma sp.); K2 is xanthan gum 2.5% + Na alginate 2.5% + conidia suspension Trichoderma sp. + talk; K3 is xanthan gum 5% + Na alginate 5% + conidia suspension Trichoderma sp. + talk; K4 is xanthan gum 2.5% + CMC 2.5% + conidia suspension Trichoderma sp. + talk; K5 is xanthan gum 5% + CMC 5% + conidia suspension Trichoderma sp. + talk; K6 is Na alginate 2.5% + CMC 2.5% + Trichoderma sp. conidia suspension. + talk; K7 is Na alginate 5% + CMC 5% + conidia suspension Trichoderma sp. + talk; K8 is control 2 (suspension of conidia Trichoderma sp. + Talc). The results obtained showed that the composition of the seedcoating formula consisting of 5% xanthan gum + 5% Na alginate + Trichoderma conidia suspension + talc up to 60 days after application of seedcoting on seeds could inactivate Trichoderma reproduction, but could not suppress the decrease in viability.

Abstract

Guided inquiry is recognized as an effective instructional model for Vocational High Schools (SMK), as it actively engages students in systematic exploration and investigation with teacher guidance. This study aims to address the problem of low student engagement and learning outcomes by implementing the guided inquiry model in classroom instruction. The research employed a Classroom Action Research (CAR) design, conducted over two cycles, each comprising the stages of planning, action, observation, and reflection.The participants consisted of 36 students from Class X of the Agribusiness for Food Crops and Horticulture (ATPH) program at SMK Negeri 1 Purwosari during the 2024/2025 academic year. Data collection instruments included student engagement observation sheets, evaluation tests, and documentation, with data analyzed using descriptive quantitative methods. The findings revealed that the guided inquiry model significantly improved both student engagement and learning outcomes in the topic of vegetative propagation. Student engagement increased from 32.81% in the pre-cycle to 70.49% in the first cycle and 84.72% in the second cycle. Similarly, the percentage of students achieving mastery in learning outcomes rose from 38.89% in the pre-cycle to 83.33% in the first cycle and reached 100% in the second cycle.
