Abstract

Project Based Learning (PjBL) has many advantages but has not been widely implemented, let alone linked to entrepreneurial activities in schools. Entrepreneurship in schools, especially those taught by chemistry teachers, still has not produced crafts that link chemical knowledge therein. The aim of the research carried out was to analyze how much influence the application of the PjBL model has in improving students' creative thinking skills and entrepreneurial interest. The research method uses a one group pretest-posttest design approach. The research sample was selected using proportional sampling with data collection techniques, namely test techniques and distributing questionnaires which were then analyzed using the paired sample t test. Based on the results of the research that has been carried out, it can be concluded that there is a positive significant difference between before and after treatment. This shows an increase in students' creative thinking abilities and entrepreneurial interest after implementing the PjBL learning model.

Abstract

Captive animals are not immune to infectious diseases, including parasitic infections that can be fatal. Prolonged periods of captivity can increase the likelihood of transmission between animals and humans. This study was conducted to identify and document the parasites that infect birds housed at Taman Rusa in the Aceh Besar District. The collected fecal samples were placed in labeled sample bottles containing formalin and stored in ice boxes. Fecal samples were collected, preserved in 10% formalin, and examined using flotation, sedimentation, formol-ether, and modified Ziehl-Neelsen techniques. The data obtained from the examination of the fecal samples were tabulated and descriptively analyzed. The results of fecal sample examinations carried out on 60 birds (representing 28 species) indicated that 39 birds (19 species) were infected with parasites. The nematode class included Heterakis sp. (3.33%), Capillaria sp. (13.3%), Trichuris sp. (6.67%), and Strongyloides sp. (8.3%). The cestode class included Hymenolepis sp. (10%), while the trematode class included Neodiplostomum sp. (1.67%). Additionally, the class Conoidasida protozoa included Eimeria sp. (33.3%) and Isospora sp. (1.67%). The highest prevalence of helminth infection was observed in Capillaria sp. infection (13.3%), while Eimeria sp. exhibited the highest prevalence of protozoan infection (35%). The findings deliver valuable guidance for veterinary health management, disease surveillance, and biosecurity strategies in avian conservation facilities. The identification of parasites with established pathogenic and zoonotic potential, including Strongyloides sp. and Capillaria sp., highlights the significance of these results for both avian health and potential public health risks.
