Tujuan dari penelitian ini adalah menganalisis pengaruh perceived usefulness dan perceived ease of use terhadap intention to use dengan sikap konsumen sebagai variabel mediator pada platform online food delivery. Analisis deskriptif digunakan untuk mengetahui karakteristik konsumen. Untuk mengetahui pengaruh-pengaruhnya, peneliti menggunakan analisis metode structural equation modeling partial least square (SEM-PLS). Dari hasil analisis tersebut dapat diketahui bahwa perceived usefulness dan perceived ease of use dapat meningkatkan attitude toward using atau sikap konsumen dan attitude toward using dapat meningkatkan intention to use pada platform online food delivery. Selain itu, perceived ease of use dan perceived usefulness juga dapat meningkatkan intention to use atau niat menggunakan kembali jika melalui variabel mediator sikap konsumen.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
