Abstract

Background: Invertebrate Zoology practicum activities require students to identify and classify types of invertebrate animals found in the environment. Phylum Arthropoda as a member of invertebrate animals had a very high number and diversity. Students had difficulties identifying arthropods using general biology books and articles from online journals that only provide general and incomplete information. The research objective was to develop android-based arthropod morphological identification media. Methods: This study used the Borg & Gall development model with stages of 1) potential and problems, 2) data collection, 3) design, 4) design validation, and 5) design revision. Design validation was assessed by the experts’ material and media experts. Validation results data has been analyzed by transforming the average of all aspects of observation qualitatively. Results: The results of the material expert validation of the arthropod morphological identification media amounted to 88.89 which was very worthy and the media experts gave an assessment of 87.5 which was very worthy. Conclusion: Media of Arthropod morphological identification to apply in invertebrate zoology practicum. Keywords : Media; Morphological Identification; Arthropoda

Abstract

The attractive appearance of soap and its various benefits make it the choice of consumers. Transparent solid soap had a transparent appearance, so it was more attractive and produced softer foam than other soaps. This research aimed to create a good combination by utilizing tofu whey waste as a transparent soap ingredient with butterfly pea flower extract (Clitoria ternatea L.) to produce environmentally friendly soap. Utilization of tofu whey waste as an alternative to sucrose and butterfly pea flower extract as the active substance triclosan from natural ingredients that contain antibacterials and antioxidants. The results of this research showed that the addition of butterfly pea flower extract produces a yellowish-white soap preparation, with a dense texture, not transparent, and a distinctive slightly sweet soap aroma. The characteristics of soap preparations from whey waste with the addition of butterfly pea flower extract had a pH of 10.7, foam stability of 70%, water content of 29%, and did not irritate.

Abstract

Molluscs are one of the most abundant invertebrate animals and live on various substrates. Peh Pulo Beach has a wide coastline, on the edge of the beach there are coral rocks, the sand is white, and the waves are big. Molluscs like to live in coral rock substrates. This research aims to determine the diversity, evenness, and richness of molluscs on Peh Pulo Beach. Sampling was carried out at three different stations using plots measuring 1x1 m which were chosen randomly. Mollusc samples were identified based on morphological characteristics and validated using the WoRMS database. The results of mollusc identification at Peh Pulo Beach showed that there were 37 species belonging to 23 families. They are classified in the classes Gastropods (32 species), Bivalves (3 species), and Polyplacophora (1 species). The diversity of molluscs in the Peh Pulo Beach area is at a moderate level. The evenness of molluscs in Peh Pulo Beach is similar. And the richness of molluscs is at a semi-disturbed level so appropriate management and conservation strategies for the sustainability of molluscs are needed.
