Abstract

The Indonesia Stock Exchange (IDX) states that stocks, including LQ45 stocks, which constitute the stock market index for the IDX, have become one of the preferred investment options for the public. Investors need to have accurate analysis and information to gain significant profits as stock prices fluctuate due to company performance, industry factors, changes in interest rates, liquidity, global market conditions, market sentiment, and investor psychology. The Gated Recurrent Unit algorithm is suitable for application on historical stock data sets because they are time series data, can be computed and compared on a numerical scale. This algorithm is a variant of the Long Short-Term Memory algorithm or other types of processing modules for Recurrent Neural Networks. The data set used consists of closing price data or close features, comprising a training data set of 4,406 data and a test data set of 1,889 data that have undergone data preparation using various techniques, including data cleansing, data scrubbing, data splitting, data normalization, and data reshaping. The results showed that the Gated Recurrent Unit algorithm is the right strategy because it obtains a good evaluation of model performance, namely MSE of 0.0009; RMSE of 0.17325 and MAE of 0.0207.

Abstract

SMKN 13 Bandung is a vocational school that prioritizes information technology, most interactions and activities utilize information technology in order to achieve the school's vision and mission. Based on observations and problems found on the SMKN 13 Bandung website, there has been no attempt to evaluate measurements of user usability and satisfaction when visiting this website. This is to ensure that the SMKN 13 Bandung website in the future can be developed and operated with optimal quality according to the experience and needs of its users. In measuring usability, this research uses the System Usability Scale (SUS) method. This is because SUS is a valid and reliable tool for testing usability even on small samples. The SUS score results obtained from measurements on the SMKN 13 Bandung website resulted in an average SUS score of 71.29. These results show that the SMKN 13 Bandung website is quite usable, acceptable but still needs to be evaluated and developed to a better stage. The results of the measurements carried out can be the first step for evaluating the SMKN 13 Bandung’s website.
