Abstract

The rapid development of data and technology in science encourages the collaboration of various disciplines to produce new branches of science, one of which is Bioinformatics, which studies molecular biology data stored in digital databases. The process of studying digital data requires special skills, such as analytical thinking skills and digital literacy. Efforts are needed to improve these two skills, one of which is by applying innovative teaching materials in project-based learning (PjBL). This study aims to determine the effect of the application of ARMOD E-Module teaching materials in PjBL on these two skills. Research with quasi-experimental methods and pretest-posttest control group design was conducted on students of the UNJ biology education study programme. The results showed that the application of ARMOD E-Module in PjBL can increase the average post-test in the aspects of segmentation ability, ability to connect system functions, ability to compare, ability to evaluate which are aspects of analytical thinking. The average post-test increases also occurred in the aspects of information and data literacy, communication and collaboration, digital content creation, security, and problem solving which are all aspects of digital literacy. The results of the one-way MANOVA test between the experimental class and the control class were 0.026, indicating a significant difference. The significant difference is thought to be due to the innovative features of teaching materials used in learning bioinformatics.

Abstract

Microplastic waste has polluted Indonesian waters, especially at Sepanjang Beach. Microplastics that are not handled properly can enter the digestive tract of aquatic animals, one of which is gastropods. The presence of microplastics must be identified in the gastropod digestive tract, considering that gastropods are also a food ingredient. Sampling was done by purposive sampling and quadratic transects. The length of the transect used is 50m perpendicular to the beach with a quadrant plot measuring 1x1 m. In each plot, 1 individual was taken for each species found. Sample preparation using 15 ml of 10% KOH solution and incubated for 1 night. Optical analysis of microplastics using a stereo microscope at 40x magnification. The most microplastics were found in the Turbo setosus species with 701 particles. The most common form of microplastic found in Gastropods and Bivalvia in the sample was fiber with a total of 2204 particles. Microplastics were also found in seawater on the beach with the form of fiber being the most commonly found, namely as many as 553 particles.
