Abstract

Shares are valuable documents that prove ownership of a company. Stock investment is one of the right choices to get more profit. There are various stocks in Indonesia, one of which is the shares of PT Bank Central Asia Tbk (BBCA). However, in making stock investments, it is necessary to analyze the data of a company that can determine the increase or decrease in a stock price. Very dynamic movements require data modeling to predict stock prices in order to get a high level of accuracy. In this study, modeling using the Long-Short Term Memory (LSTM) algorithm to predict BBCA stock prices. The data used is secondary daily data obtained from securities with a date range of January 3, 2011 to December 30, 2022. The main objective of this research is to analyze the accuracy of the LSTM algorithm in forecasting stock prices and to analyze the number of epochs in the formation of the optimal model. The optimal epoch variation is obtained with the number of epochs of 5 and batch size 1. The resulting values include Mean Absolute Error (MAE) of 96.92, Mean Squared Error (MSE) of 16185.22 and Root Mean Squared Error (RMSE) of 127.22. The results of this study provide further insight into the performance of the LSTM algorithm in stock price prediction and show that with the right parameter settings, it can be a useful tool for investors in making better investment decisions

Abstract

The increase in online-based services makes a security system for server computers increasingly needed. A server computer is a device that must always be available to be accessed anytime and anywhere. Some of the security systems needed for server computers include security for ssh port access for remote server access needs and a security system to protect servers from Denial of Service (DoS) attacks which can make the server down and completely inaccessible. In this study, a security system is proposed for a server computer with the Linux CentOS operating system on a port 22 secure shell(ssh) access system using the port knock method and a security system to prevent Denial of Service (DoS) attacks on server computers using the RST Cookies method. The simulation results from the port 22 Secure Shell (SSH) access experiment for the server computer can work well where port 22 Secure Shell(SSH) will remain closed and cannot be accessed carelessly except by accessing several ports first according to predefined port knocking rules. Likewise, the implementation of a security system with the RST Cookies method works very well to prevent Denial of Service (DoS) attacks and can still keep the server accessible with a good response time of under 1 ms

Abstract

The purpose of this study is to reduce the dimensions of the dataset that affect the prediction of breast cancer. The data used in research is very much data or is called high-dimensional data. The use of classification algorithms has weaknesses when used on high-dimensional data, so an appropriate method is needed to reduce the dimensions or variables used. There are several methods that can be used to reduce dimensions. In this study using the method of linear discriminant analysis (LDA). LDA is a supervised machine learning algorithm that is used to classify data into several classes, using a linear technique to determine the best set of linear variables to unify class data. LDA is used to reduce the dataset variables used by retaining information that is important for the classification process. The method used in this research is using LDA in data processing and then using a logistic regression model for the classification process. The conclusion obtained in this study is that LDA can overcome the problem of multiclass classification. The results obtained were 16 wrong cases out of a total of 455 cases so that the results obtained were 0.035% misclassification.

Abstract

The point of sale (POS) system is not something foreign to prominent entrepreneurs, this system has long been used by large-scale business actors, but generally, a system like this has complex features and its operation requires special personnel, therefore in the all-digital era Currently, there are still many small entrepreneurs using traditional processes in managing their businesses due to limited access to technology and costs, this will undoubtedly take time and reduce business productivity compared to using modern management systems. Then we need a POS that is easier to access and does not require large costs by small or medium-scale businesses, because it will be the right solution for business management with a lot of manual work automated by the system, such as profit and loss calculations, information on the availability of goods, information on quantities goods, and transaction processes using a scan code where the total payment and change will be calculated automatically by the system, of course with the presence of this point of sale system it will make it easier for small and medium business actors because the system is available in the form of mobile application which can be accessed easily by many business groups.

Abstract

Cooperatives are social organizations or economic bodies that have a very important role in the growth, development of economic potential and community success. One of the cooperative activities is the provision of credit or loans to community members. Cooperative credit is one of the most important banking activities and serves to provide credit to the community. In practice, errors often arise due to inaccurate credit analysis, or the behavior of the customers themselves. The purpose of this research is to compare the accuracy results between the Naive Bayes algorithm and Support Vector Machine (SVM), where the best accuracy results can later be used as a reference to determine the profitability of lending. The attributes used in this study consist of 11 attributes, namely: Gender, marital status, occupation, relatives, nominal income, income criteria, loan amount, loan term, interest rate, installments and class as income characteristics. The dataset used in this study includes 166 members of the Daru Nahdla Capita Shari'ah cooperative. The results of testing the naive bayes algorithm after dividing the data five times, dividing the data set 70% as test data and 30% as training data, obtained a precision value of 97.00%, recall 100.00%, F1 score 99.00%. and accuracy 98.00%. Thus, the Naive Bayesian algorithm is an algorithm that shows accurate classification and prediction

Abstract

In this era, the development of technology in the field of transportation is growing rapidly. This causes the number of vehicles used to facilitate the activities of most people, the need for private vehicles also increase. This condition is increasingly causing overcrowding, especially in rural and urban areas. In order to prevent overcrowding of these vehicles and reduce the rate of accidents on the highway, a traffic light or commonly called a traffic light is needed at every intersection or crossroads. Traffic lights are lights that control and regulate the flow that occurs in traffic. But most motorists lack in obeying traffic rules. In traffic regulations, there is also a zebra cross facility, which serves as a marker for motorists that there is a path for pedestrians to cross the road. However, in reality, even though the number of zebra crossings is quite large and has a size that can be seen, it doesn't seem to work properly. This phenomenon occurs because the increase in the number of motorized vehicles is not accompanied by an increase in public awareness. So we need a tool to make it easier for pedestrians to pass the zebra cross and provide convenience for officers to monitor traffic violations. The tool is a prototype of a motorist violation detection device passing through a zebra cross based on Internet of Things technology using the infrared Proximity Sensor E18-D80NK which is used to detect objects within a distance of 3-80 cm, the buzzer will issue an alarm sound as a warning to comply with traffic regulations in accordance with set. ESP32-Cam to capture images when the driver persists in violating traffic signs and the image will be sent via telegram.
