Abstract

The use of organic fertilizers is considered to be beneficial by farmers such as increasing land productivity. Corn farming contributes the highest agricultural waste in Indonesia, such as stem litter, leaves and husks. This waste has the potential to be used as organic fertilizer because based on research it contains many nutrients in it. This study aims to evaluate the effectiveness of EM4-based microbial treatment in accelerating the composting of corn litter waste through observational qualitative analysis. The results of this study indicate that the addition of microorganisms can shorten the time to make organic fertilizer. On the 6th day, the corn litter waste sample that had been given EM4 had shown the appropriate criteria for organic fertilizer in the form of a neutral pH concentration of 6.5 and did not have a disturbing odor and a texture that was no longer stiff. These findings suggest that EM4 can be used to accelerate composting of corn waste into high-quality organic fertilizer, potentially supporting sustainable agriculture.

Abstract

Genetic concepts, particularly DNA technology, often lead to misconceptions among students. Integrating a virtual laboratory (VL) into coursework presents an innovative approach to enhancing concept understanding and visual literacy through interactive, story-based simulations that bridge theory and practice. This study aimed to analyze the students' concept understanding and visual literacy improvement by applying a VL to teach DNA Test Simulation (Paternity Test) using a contextual narrative method. The research was conducted in the Science Education undergraduate program with a purposive total sampling of students enrolled in Genetics (First Semester 2024/2025), utilizing an open-source web-based VL platform. Pretest and posttest assessments measured students' concept understanding and visual literacy before and after VL integration. The findings reveal a significant improvement, with concept understanding rising from an average pretest score of 42.6 to posttest 69.9 (N-Gain 0.46) and visual literacy increasing from 53.8 to 71.8 (N-Gain 0.37). Furthermore, 97% of students were satisfied with the VL-based learning method. This research contributes to knowledge and science development by demonstrating that VL can improve concept learning and visual literacy in genetics education. It offers an accessible and scalable solution for teaching complex DNA technology concepts, reducing reliance on costly wet laboratory experiments while maintaining scientific rigor. Beyond academia, the study supports broader educational equity, making advanced molecular biology concepts more available to diverse learners and fostering scientific literacy in society.

Abstract

Artikel ini bertujuan mengusulkan adaptasi model pembelajaran berbasis Orton-Gillingham (OG) yang terintegrasi dengan pendekatan visual sebagai solusi konseptual dalam pembelajaran sains, khususnya pada materi gaya dan gerak, bagi siswa dengan disleksia. Pendekatan OG dikenal efektif dalam membantu siswa dengan kesulitan membaca melalui strategi multisensori yang terstruktur dan eksplisit. Dalam konteks pembelajaran sains yang menuntut pemahaman konseptual dan representasi simbolik, integrasi media visual seperti kartu konsep, peta konsep, dan simulasi digital berbasis PhET diharapkan mampu memperkuat pemahaman siswa disleksia terhadap konsep gaya dan gerak. Artikel ini mengembangkan kerangka konseptual pembelajaran yang mengedepankan diferensiasi visual guna mengatasi hambatan literasi sains pada siswa dengan kebutuhan khusus. Model ini diharapkan menjadi rujukan alternatif dalam merancang pembelajaran sains yang inklusif dan berbasis bukti.
