Abstract

Technological advances in the field of mobile applications for online purchases, especially those involving food and beverages, have grown significantly in the current era of globalization. To overcome this problem, the reviewer uses QR code scanning technology. This QR code technology was chosen because it can offer a very fast, simple, precise and mechanical data collection method. The purpose of designing this application is to make it easier to order food and drinks using QR-codes. In this study using the Linear Search Algorithm method as a search for food and beverage data. Linear Search works on unordered or ascending text sequences. he looks for data by comparing one by one the elements of a set, write them in a table or array, by starting the search on the first element in the sequence of a set. From the results of the tests that have been carried out, it can be seen that the earlier the position of the food and beverage menu data that is being searched for, the longer the program will take to find the intended data, the faster it will be. Meanwhile, the later the data menu position you are looking for, the longer the program execution time will be. Here proves that the index position of the data you are looking for is very influential on the speed of searching for the data. So that the average value is obtained as follows, the data is in the initial position 0.25 seconds, the middle position is 0.27 seconds, the final position is 0.29 seconds. While the use of memory that is used both eat the same memory storage, which is 523kb.

Abstract

Currently, many automation systems have been implemented in various fields, one of which is animal husbandry. There are many hobbyists who want to keep turtles, both for care and for business. It is quite difficult now to be preoccupied with matters that require leaving the house. Therefore the owner must have a lot of free time to care for the turtles. In fact, keeping turtles is also not easy, there are many obstacles to face. One of them is to provide feed manually by still using human power, therefore the aim of this research is to make an automatic feeding device to make it easier for turtle keepers to provide feed automatically with a set time that can be determined. This study uses ESP8266 as a hardware platform to connect to a Wi-Fi network. In this study monitoring feed via the web and connected to the tool to be made, the author integrates ultrasonic sensors for testing based on the percentage of remaining feed that comes out, with the method used, namely Fuzzy Logic to calculate the percentage of the remaining feed that comes out. By using an ultrasonic sensor this research has been successfully carried out according to the main purpose of the research, the results of this test have been carried out and got the desired result of the author, namely 100, which means that if the feed capacity is 8cm during the day, the servo will open according to the action given, and it can be concluded that this research has been successful.
