Abstract

problem that often occurs is the difficulty in determining the average bad credit spread across 7,823 savings and loan cooperatives in Indonesia. The main problem faced by savings and loan cooperatives is the difficulty in identifying and mitigating credit risks that can cause bad credit. Bad credit not only harms cooperatives, but can also disrupt the financial stability of cooperative members. The lack of effective tools to measure and predict credit risk makes cooperatives potentially face unnecessary losses. The aim of this research is to apply the C4.5, SVM, and KNN algorithms in determining the average non-performing loans of savings and loan cooperatives, comparing the results and performance of the three such algorithms in the context of credit risk management, and improve understanding of the use of machine learning techniques in identifying credit risk patterns that may be difficult to detect manually. The application of the C4.5 Algorithm, SVM (Support Vector Machine), and KNN (K-Nearest Neighbors) models in determining the average bad credit in the context of savings and credit cooperatives is carried out by considering the appropriate configuration. This research first collects and preprocesses data which includes credit history, income, length of membership, and other related factors from savings and loan cooperatives. Next, factor analysis and feature selection are carried out to identify the factors that most influence credit risk. The results of the three models are evaluated using various evaluation metrics, such as accuracy, precision, recall, F1-score, and AUC-ROC. The results of this research The results show that the SVM model has the highest performance in predicting credit risk, followed by the C4.5 and KNN algorithms. Careful feature selection and robust model validation are also key components in accurate credit risk assessment. Thus, the results of this research can help cooperatives better manage credit risk and make more informed decisions regarding loan approvals.

Abstract

Video Games are games that use electronic device technology that provides images as a medium that is related to the user and the user can control the objects that are in the picture with a controller (Input Device). During the times, Video Games have other output media (output) such as sound and vibration. Budi Luhur University has a community that prioritizes Creative Boxes, which is a video game developer community at Budi Luhur University. Creative Box Community has made several games for the Android and PC platforms. However, this community has never implemented a special Artificial Intelligence (AI) technique in the game title created by the Creative Box community. Therefore, the main objective of this Final Project is to create AI content in the Third Person Shooter (TPS) genre as the main opponent, because the TPS genre is used as the main opponent as the main source. For this reason, the Pathfinding Method is needed to determine the direction of the road and the Decision Tree as the determinant of the action (behavior) of the main opponent. Pathfinding method uses Algorithm A *, how to take by taking the distance between each node and destination. The Decision Tree method is a hierarchical tree that is implemented using Nested if-else, each condition will be made and a decision is made based on the condition.

Abstract

The use of automated technology has advanced enough that routine tasks can now be performed automatically because people don't always follow rules. Automation can be used to assist ordinary jobs if they can be performed continuously regardless of the passage of time. We can utilize this contemporary technology in the fields of plantations and agriculture to get far better outcomes and maximize time efficiency. Small computers are the latest technical advances that can assist humans in carrying out routine tasks. The name of this device is microcontroller. To produce intelligent internet of things based tools that will facilitate plant care in the future, this research set out to do just that (IOT). So that it can be used in plant maintenance, especially for the maintenance of aglaonema plants which can monitor automatically whenever and wherever we are, whether we are still working, sleeping, or on vacation. A device for watering plants in a greenhouse made with a microcontroller embedded fuzzy logic system in the form of a multi-system, with three inputs for soil moisture fuzzy sets and temperature fuzzy sets for the surrounding environment. The tool can operate according to the requirements of the fuzzy logic method by carrying out routine tests. We can make a prototype that can water the plants automatically and monitor the level of soil moisture and temperature coming from the sensor via the internet using the Arduino microcontroller along with sensors such as the YL-69 soil moisture sensor and the DHT11 temperature sensor. The results of the plant watering prototype show that it can operate effectively based on a predetermined schedule and soil moisture value limit. The prototype will water at 07:00 and 17:00 and will water liquid fertilizer at 08:00 and 18:00 if the soil moisture reading is greater than 700. Electricity must flow through this device

Abstract

PT XYZ, a startup in the Information Technology sector, developed an asset management application to digitalize the asset management process for its clients. However, as new features were added, the application became more complex, causing difficulties for new users. PT XYZ responded by introducing a customer service system to assist new users in exploring the company’s services and application features. To improve service efficiency while maintaining quality, the company opted to implement a chatbot. The chatbot was designed to provide automatic and responsive assistance, reducing the load on the customer service team and increasing user satisfaction. The author integrated NLP and NLU in designing the chatbot for PT XYZ using the open-source RASA framework. This framework was chosen for its strong capabilities in natural language processing and understanding conversational context. The NLP and NLU models are used to create a customer service engine in the form of text messages that answer questions specifically related to the use of the asset management application. By leveraging this technology, the chatbot can provide relevant and accurate responses, even when faced with variations in language and complex questions. Based on black box testing, the chatbot successfully recognized the intent behind user queries. The testing was conducted to evaluate how well the chatbot understood and responded to user questions. The results, using a confusion matrix, showed that precision, recall, accuracy, and f1-score all achieved a perfect score of 1.0.
