Abstract

Augmented Reality (AR) applications that use 3D object tracking are still rarely used. This is because the appearance of information expected from a real object that is used as a marker is often slow and difficult to detect by the camera. The taking angle and lighting are part of many factors that influence marker detection. This study applies an experimental method by building an AR application using 3D object tracking by testing 2 variables, namely the angle and light intensity. The purpose of this study was to see the effect of light angles and intensity on the reading of 3D objects. The results obtained show that the effect of angle is inversely proportional to the magnitude of the light intensity. In other words, the appearance of 3D objects from the AR application is greatly influenced by conditions with bright light at a small angle. The level of light intensity is very influential on object detection. This can be seen from the average light flux (lumen) obtained, which is at an angle of 90° with lumen 205Cd. 3D object tracking applications can be used by the wider community in studying and getting to know building spatial plans.

Abstract

This research was conducted in January 2024 in the waters of Lukit, Merbau District, Meranti Islands. This study aimed to analyze the total oil content and abundance of planktonic diatoms and determine the relationship between total oil content and abundance of planktonic diatoms. This study used a purposive sampling method. The sampling location was divided into three stations with three sampling points. Station 1 is in the oil company jetty area, Station 2 is in the crossing port area, and station 3 is far away from residential areas. The results of the analysis of total oil content was 0,252 ppm. The highest oil content was found at station 2, which was 0,274 ppm, and the lowest oil content was found at station 3, which was 0,222 ppm. The results of the planktonic diatom abundance ranged from 75 – 187,5 ind/L. The highest abundance was found at station 3, which was 166,67 ind/L, and the lowest was found at station 2, which was 79,17 ind/L. The results of the simple linear regression test obtained the equation y= 177,77-225,55x with the value of R² = 0,1321 and the correlation coefficient r = -0,36, which shows that higher total oil content will cause a decrease in the abundance of planktonic diatoms
