Abstract

One of the Indonesia's leading online food delivery services is Shopee Food. It has competed with other big players. This application has caught the attention of users, even those from the Z generation, who are known for their easy-to-move characteristics and are close to technological applications but sensitive to user experience. This generation's convenience is influenced by many factors. This study analyzes the factors that influence attitudes and behavior for sustainable use of this application in Jakarta. Quantitative data is collected using a survey and questionnaire. This PLS-SEM modeling study shows that after using the service in this application, the user's hedonic motivation must be followed by comfort and usability. The user will evaluate the post-use usefulness of the previous experience to form an attitude toward the next perceived experience. Behavioral intentions toward sustainable use are encouraged. This study highlights the importance of usability and ease of use in determining user comfort. Generation Z does not easily form positive usage attitudes until the benefits of the next experience are the same or better.

Abstract

Impact testing is carried out to determine the strength of the material against shock resistance, such as brittleness caused by heat treatment or the brittleness of the casting product and the effect of the shape of the product. This test is carried out on a testing machine designed by having a pendulum with a certain weight that swings from a height to provide shock loads, in this test there are two kinds of testing methods, namely the "Izod" method and the "Charpy" method which differ according to the direction of loading on the test material and the position of the test material. This study aims to determine the ductility of ST 37 steel and aluminum from smelting beverage cans combined with oil. The research method used in this research is a direct review in the field then conducting data collection and literature studies including taking report sources from various books, both in campus libraries and libraries outside the campus. The results showed that 1) The impact price on aluminum material was obtained 0.057 Joules / mm2 with the energy given at 4,588 Joules. 2) The impact price on ST37 steel material is 0.192 Joules/mm2 with Energy given at 15.34 Joules.
