Abstract

Apu-apu (Pistia stratiotes) is a hyperaccumulator plant for lead (Pb), whereas apu-apu is widely consumed by the public. This study aimed to determine the growth and lead content (Pb) of Apu-Apu at various doses of organic fertilizer; and to determine the most effective dose of organic fertilizer to increase growth and reduce lead (Pb) content in Apu-apu. The study was conducted in a completely randomized design (CRD) with treatment with organic fertilizer at a dose of 0 grams, 50 grams, 100 grams, 150 grams, 200 grams, and 250 grams in 2 kg of soil from Ambon TPA. Each treatment was repeated 4 times and carried out for 4 weeks. Observations included plant height, number of leaves, leaf length, root length, and plant wet weight. At week 4, measurements of lead (Pb) levels in the leaves were carried out. ANOVA and 5% BNT were tested. The results showed that the application of organic fertilizer can increase the growth of Apu-apu plants. The most effective dose for Apu-apu plant growth is 200 grams in 2 kg of soil. The application of organic fertilizer could not reduce the Pb content in the Apu-apu plant.

Abstract

Objective: This study explored the integration of multimodal texts in language learning within the Merdeka Belajar curriculum framework, which emphasizes four core competencies aligned with the 21st-century educational goals. Method: Using Arts-Based Educational Research (ABER) with the Art in Research approach, we developed a music and poetry video depicting the Puragabaya Legend from Galunggung, Tasikmalaya as an innovative digital teaching material. Result: The creative process successfully produced digital performance that meets both aesthetic and educational requirements. The Puragabaya Music and Poetry Video demonstrates an effective integration of verbal metafunctions (narrative structure and cultural storytelling) and visual metafunctions (symbolic imagery and representational elements) that enhance students' comprehension and cultural understanding. The video effectively bridges traditional storytelling with contemporary digital literacy demands, providing concrete examples of metaphorical language use within authentic cultural contexts. Novelty: This research contributes to educational innovation by demonstrating how arts-based digital materials can serve both pedagogical and aesthetic functions, offering a replicable model for integrating local cultural content into language learning curricula through creative multimedia production.
