Measurement of human body weight is an important process in various contexts, such as medical staffing administration, military recruitment, and individual health assessment, as body weight is a key parameter for determining one's body condition. Weight information is traditionally obtained using manual scales, which have been used for many years. However, manual weight measurement is quite time-consuming, especially when done for many people and repeatedly, such as in military recruitment or medical administration. A new approach using digital image technology offers improvements in this process. Therefore, this research aims to calculate human body weight based on digital photos using the Body Surface Area (BSA) method. The use of the BSA method in digital image-based weight measurement involves calculating the body surface area to estimate body mass. This method combines parameters such as height and body circumference taken from the photo image to calculate BSA. Furthermore, an investigation into calculation analysis and accuracy enhancement is conducted. The calculated weight results from the photos are then compared with the scale results to determine their accuracy. Based on the calculation results, an approximate value of 93.3% accuracy is obtained with an average conversion factor of 0.978 at a distance of 300 cm between the camera and the object.

This research applies the Monte Carlo simulation method to predict the movement of Apple Inc.'s stock price over a long period of time. Using historical data of Apple's stock price from 12 December 1980 to 24 March 2022, this study aims to generate a probability distribution of the future stock price. The method involves several steps, including data collection, log return calculation, parameter estimation, and simulation of the stock price path through random iterations based on the log return distribution. The simulation results show that the closing price of Apple stock can be predicted by following the historical trend, although there are differences with the real data due to the stochastic nature of the Monte Carlo technique. This research also applies a variance reduction method to improve simulation efficiency. The findings provide a valuable perspective for investors and financial analysts in identifying investment risks and opportunities through an in-depth understanding of the dynamics of stock price movements using Monte Carlo simulation. Suggestions for future research include the use of VaR methods with historical variance and covariance approaches, as well as considering longer data periods and more stock indices for more comprehensive results.
