Development of augmented reality application for introducing tangible cultural heritages at the lampung museum using the multimedia development life cycle

Museum Lampung is one of the largest museums in Lampung Province which has a collection of tangible cultural heritage. If the museum visitors are seeking information about the collections, they will be assisted by museum guides orally. However, the limited number of guides are not enough to serve visitors during the school holidays. Therefore, to help visitors to find information about its cultural heritage collection, Augmented Reality (AR) technology was developed. AR is a technology that can display 3D objects in a real environment. The AR application that will be built is developed with the MDLC approach, where this method is suitable for developing multimedia applications. This research produces an application that can display 3D objects when the user's camera is directed to the collections of Museum Lampung and provides information related to these objects. Based on the test results on aspects of perceived usefulness, convenience, intention, and user friendliness, generally respondents answered "Agree" with a percentage of 83%. This indicates that the application is acceptable to the user.

Glucose level detection system in glucose solution using TCS3200 sensor with If-Else method

Early and routine examination of glucose levels plays an important role in preventing and controlling diabetes mellitus and maintaining the quality of life. Checking blood sugar levels by hurting the body (invasive) can lead to infections caused by needles. As an alternative, the examination is carried out in a non-invasive way using excretory fluid in the form of urine, which is reacted with Benedict's solution that create a color change. Experts in the laboratory only carry out an examination using non-invasive methods because in determining glucose levels, it requires accuracy and eye health factors. Therefore, a glucose level detection system was created using a sample of glucose solution to determine the system's parameters using the if-else method. The glucose level detection system is conducted by mixing the glucose solution with Benedict's solution to produce a color change. Then the reaction results are read by the TCS3200 sensor and processed by Arduino to be classified, according to predetermined parameters. The decision results based on the classification of the glucose level parameters that have been determined are displayed on a 16x2 LCD. The results achieved in this study on 10 samples of glucose solution that were tested and processed by the if-else method were successfully read and classified based on predetermined parameters.

Development of academic information system using webassembly technology

The Academic Information System (in Indonesian often abbreviated as SIAKAD) is a system developed to manage student data that aims at facilitating online academic administration activities. It aims to provide academic information services in the form of web applications, where teachers can independently create student academic reports to synchronize data into the DAPODIK system, a primary education data system, and develop academic information systems using web assembly according to user experience (UX) and developer experience (DX). The research method consists of field studies and literature related to web assembly, primary education data (DAPODIK), and the Academic Information System (SIAKAD). This information system and database were built using the Convention Over Configuration paradigm. The design phase used a prototyping model to graphically represent the system workflow and used an experimental research approach. Moreover, the study used an integrated modeling language (UML), and a Database Management System using PostgreSQL, and alpha testing for model testing. The Client Application was built using the C# programming language for users to generate student academic reports every semester. Processing data transactions using web assembly took less time than the traditional web, which was less than 300 milliseconds.
