Abstract

This study aims to analyze student needs and describe student responses to the limited trial of a revitalized Human Anatomy and Physiology (HAP) laboratory manual integrated with QR Codes as multimedia enrichment access. Revitalization here refers to the comprehensive updating of an existing module, encompassing content substance, procedural instructions, materials alignment, and the addition of digital media via QR Codes. The study employed the ADDIE model; data were collected through four Likert-scale questionnaires and one open-ended evaluation sheet, analyzed descriptively using quantitative and qualitative approaches. Needs analysis involved 57 active students and 23 alumni; the limited trial was conducted with 33 students for one practicum topic due to time constraints. Results showed a very high practicality level with an average student response score of 91.3%. QR Code integration proved effective as a comprehensive pre-lab guide, and qualitative feedback from laboratory assistants confirmed a significant reduction in repetitive technical instruction. This study is limited in scope, covering only one of six practicum topics, and formal expert validation was not conducted.

Abstract

The Andalas River is located in Seluma Regency, Bengkulu Province and is used by the community as a source of raw water for PDAM, however, river rock mining activities, waste disposal by rubber factories, and water extraction have the potential to reduce the water quality of the Andalas River. This research aims to analyze the diversity and abundance of phytoplankton as a bioindicator of water quality in the Andalas River. Sampling was carried out in March-April 2026 at three stations using a purposive sampling method using a plankton net, then analyzed using the Shannon-Wiener index (H'), uniformity (E), and dominance (C). The research results found 51 types of phytoplankton from 8 divisions, namely Bacillariophyta, Chlorophyta, Euglenophyta, Charophyta, Cyanophyta, Dinophyta, Ochrophyta, and Cryptophyta, with the most dominant division being Bacillariophyta. The highest diversity and abundance was found at Station 1 (32 species; 286 individuals/L; H' = 3.323), followed by Station 2 (28 species; 137 individuals/L; H' = 2.986), and Station 3 (23 species; 105 individuals/L; H' = 0.177). The dominance index values ​​for the three stations are close to 0, indicating that there are no species that dominate excessively. Water quality varies from good condition (Station 1), moderately polluted (Station 2), to heavily polluted (Station 3). Physico-chemical parameters in the form of pH, temperature and DO show that river conditions are still within the range that supports phytoplankton life.
