Table tennis is indeed a sport which involves or four people hitting a lightweight ball back and forth across a surface using small wooden rackets. Table tennis players must retrieve played balls off the field's floor, even though numerous balls are used and played during training sessions. As a result, collecting is a time-consuming and exhausting procedure. Pick up hoppers and tubes are some of the equipment and systems used to make the collecting process easier. In this paper, we designed and built an autonomous Table Tennis Ball Retrieving Robot that can collect up to 5 balls at once. An acrylic frame supports the robot, which is guided by four separately controlled wheels. The table tennis balls are sucked into a lightweight basket on top of the robot by a rotating fan. The fan is driven by a brushed motor with a high RPM speed.
Swamedikasi atau pengobatan sendiri tanpa resep dokter mengalami peningkatan saat pandemi COVID-19. Peningkatan ini mendorong pentingnya mengetahui gambaran pengetahuan, sikap dan tindakan (KAP) konsumen swamedikasi terutama yang mengalami gangguan sistem pernapasan saat pandemi COVID-19. Penelitian ini dilakukan untuk mengembangkan kuesioner dan melakukan validitas terhadap instrumen yang akan digunakan untuk mengetahui KAP konsumen swamedikasi gangguan sistem pernapasan di apotek Kota Surabaya saat pandemi COVID-19. Penelitian ini menggunakan metode kuantitatif survei yang dilakukan terhadap 201 responden di 15 apotek Kota Surabaya. Kuesioner KAP dikembangkan dengan pendekatan Health Belief Models (HBM) dan divalidasi menggunakan Confirmatory Factor Analysis (CFA). Penelitian ini menghasilkan 18 butir kuesioner (3 faktor masing-masing 6 butir kuesioner) dengan factor loading terbaik. Semua factor loading secara statistik signifikan dan menunjukkan nilai di atas 0.4. Nilai indeks ketepatan model ditunjukkan oleh RMSR = 0.032 , GFI = 0.874, TLI = 0.914 , CFI = 0.93 , dan RMSEA = 0.072. Realibilitas diukur dengan menggunakan rumus Construct Realibility (CR) dengan hasil masing-masing 0.819 (faktor pengetahuan), 0.855 (faktor sikap) dan 0.860 (faktor tindakan). Kuesioner KAP pada penelitian ini merupakan instrumen yang valid dan reliabel untuk mengetahui gambaran pengetahuan, sikap dan tindakan konsumen swamedikasi gangguan pernapasan selama pandemi COVID-19.
