Development and Validation of Microbiology and Parasitology Laboratory Manual for Science Education

2025-05-30T10:09:49+07:00

Purpose of the study: This study aimed to develop and validate a Microbiology and Parasitology Laboratory Manual specifically designed for Science Education students, in alignment with the Commission on Higher Education (CHED) Memorandum Order No. 75, series of 2017. The manual seeks to bridge theoretical knowledge with practical application through structured, inquiry-based laboratory activities that cultivate scientific skills, promote critical thinking, and reinforce adherence to laboratory safety protocols.

Methodology: The validation process was conducted in two phases. First, subject matter experts in microbiology, parasitology, and science education evaluated the manual based on content accuracy, instructional clarity, relevance, alignment with CHED competencies, and pedagogical soundness. Their feedback was systematically integrated to enhance the manual’s quality. Second, pilot testing was conducted with science education students to assess usability, engagement, and impact on learning outcomes. Data were collected through expert validation checklists, student perception surveys, and performance assessments during laboratory sessions.

Main Findings: Findings revealed that the manual was highly satisfactory across all validation criteria. Quantitative and qualitative results from pilot implementation demonstrated significant improvements in students’ comprehension of microbiological and parasitological concepts, laboratory competencies, and overall engagement.

Novelty/Originality of this study: This study offers a discipline-specific, standards-aligned laboratory manual developed for teacher preparation, filling a critical gap in localized instructional materials. It emphasizes not only scientific content but also the pedagogical approaches needed for future educators, contributing to quality enhancement in science teacher education.

Factors Influencing Farmers’ Interest in Using Trichoderma sp. for Chili Cultivation in Giritirto Village, Gunung Kidul

2025-05-30T10:09:46+07:00

Purpose of the study: This study aims to identify and analyze the internal and external factors that influence farmers’ interest in using Trichoderma sp. as a biological control agent for chili cultivation in Giritirto Village, Purwosari Subdistrict, Gunung Kidul.

Methodology: This study used a quantitative approach with purposive and random sampling methods. Data were collected through observation, interviews, questionnaires, and documentation. Instrument testing employed Microsoft Excel. Data analysis included validity and reliability tests, classical assumption tests, and multiple linear regression using SPSS software to assess the influence of various independent variables.

Main Findings: The study found that farmers' interest in using Trichoderma sp. was generally high. Among the factors examined, the role of extension workers and the availability of facilities and infrastructure had a significant positive effect on farmers' interest. In contrast, age, education level, and farming experience did not have a significant influence on their interest in adopting Trichoderma sp..

Novelty/Originality of this study: This study uniquely explores the socio-demographic and institutional factors influencing farmers’ interest in adopting Trichoderma sp., which has rarely been addressed in previous research. It provides new insights into the human dimension of sustainable agriculture adoption, offering practical implications for policy and extension strategies to promote environmentally friendly farming practices.
