Development of Mobile Application for Freezing Point Calculation in Ice Cream Mixes

Abstract

Traditional manual calculation method for ice cream freezing point based on the predefined formula applying linear interpolation requires too complicated steps to achieve. The result is, it takes too much time and effort to find an output. Additionally, Microsoft Excel spread sheet is easier for user but it must be executed by computers not friendly to smartphones. Some of these Excel files requires Internet connection to retrieve some necessary data or formula to calculate. Therefore, mobile application is great solution and it is more user-friendly than manual method and spreadsheet in term of real-life use. This work applied linear interpolation equation and Java for Android to create a mobile application capable of calculating initial freezing point of ice cream which affects ice cream quality under the storage. Once, users download and install it from Google Play Store. It works efficiently without advertising nonfiction or any in-app purchase requirement. It is available even on the offline mode. Its interfaces come in graphical designs a lot easier than its predecessors. Then, user is capable of using it single handedly while other preparation of ice cream is also running concurrently.
