Abstract

Indonesia has attractive tourist destinations for tourism such as beautiful interior areas and historical places. The purpose of this research is to design and build a virtual tour application for Aceh tourism objects using augmented reality. One of the problems that occur in tourist objects is that foreign tourists do not have an idea about the tourist objects they want to visit. The technology used in this study and previous research is Augmented Reality, but previous research only displays 3D tourist objects, while in this study, augmented reality technology is incorporated into the design of the 4 Aceh tourist attractions by showing a 3-dimensional illustration of the object as a whole. for the outside of the building and displays a virtual tour image in the form of a video to illustrate the inside of the tourist attraction building on the Android mobile platform. Based on the results of distance and angle testing, the best (ideal) distance that produces clear and bright marker detection is found at a distance between 25 to 45 cm, while the best angle is between an angle with a slope of 0° to 60°. Measurements of distances and angles are carried out using threads, bows and measuring tapes. The 3D object is successfully displayed by pointing the camera at the marker to be detected.

Abstract

The process of monitoring the drying of coffee beans so far is still done traditionally so that the effectiveness of the drying process is still low. The IoT-based drying monitoring process is expected to provide better effectiveness and time efficiency. This research designs and manufactures a solar dryer with natural convection heat transfer for coffee beans equipped with an Internet of Things-based monitoring system. The purpose of this study is to develop the performance of a solar dryer with natural convection with the addition of an IoT-based monitoring unit. The research begins with a technical plan for the main components of the dryer. Components whose shapes, dimensions, and materials have been planned will be outlined in the form of detailed technical drawings. Detailed technical drawings will be a guide in the dryer manufacturing process. The main components of the dryer are solar collectors, drying chambers, and an IoT-based monitoring system. The solar collector will function to capture heat from the sun which will flow naturally into the drying room. An IoT-based monitoring system will capture the temperature and humidity (DFRobot DHT22 sensor) in the solar collector, drying room, and the environment of the dryer. In addition, a Bh1750 sensor to capture the intensity of the sun is also embedded in this monitoring system. This monitoring system will be connected to the internet network where the data will be sent to a cloud data server. The recorded data can then be downloaded using a mobile device or personal computer connected to the internet network. This IoT-based monitoring system was chosen so that performance data from the dryer can be monitored in real-time and online. The results of this study are a prototype dryer with a household capacity of 9 Kg equipped with an IoT-based monitoring system has been built and can be implemented properly
