Abstract

Coffee beans are the seeds of the coffee plant and are the main source for coffee drinks. In Indonesia, there are two main varieties of coffee beans developed, namely Robusta Coffee (Coffee Robusta) and Arabica Coffee (Coffee Arabica). Coffee is one of Indonesia's main export commodities, occupying the third position in the world after Brazil and Vietnam. This research aims to determine the criteria in determining the selection of quality coffee beans through the Weighted Aggregated Sum Product Assessment (WASPAS) and Additive Ratio Asessment (ARAS) methods. This is done to simplify the process of selecting quality coffee beans. This research uses 5 criteria, namely: Price, Color, Aroma , Taste , and Impurity Content . The results of the study show that the ratings resulting from the application of the two methods have similarities. The best alternative identified after the application of both methods is the C7 alternative. Using the WASPAS method, the C7 alternative obtained a reference value of 0.5255. Meanwhile with the ARAS method, the C7 alternative gets the highest reference value, which is 0.9908.

Abstract

Credit is a form of financing for most economic activities. Credit is an important activity for cooperatives, because credit is one source of funds for cooperatives. Before starting credit granting activities, a good and thorough analysis of all aspects of credit that can support the credit granting process is required, in order to prevent the emergence of credit risks and the emergence of irregularities, one of which is bad credit. Therefore, it is necessary to have a system that can support decision making in providing credit. With the decision support system created, it is hoped that it can help the cooperative chairman in analyzing credit and reducing the level of bad credit in the cooperative. For the Probabilitic method there are 3 highest alternatives, namely in the first place with the name Pratiwi Amalia getting a value of 0.604, second place with the name Helmi Yanti getting a value of 0.475, third place with the name Cut Arpiah Hasibuan getting a value of 0.439

Abstract

The rapid development of computer technology has had a significant impact on various sectors, including education. The utilization of information technology systems plays a crucial role in supporting data processing and effective, efficient decision-making processes. At SMA Swasta Panti Budaya, the selection of extracurricular activities by students is still conducted manually, which often leads to confusion in choosing activities that match their interests and potential. This can result in a lack of student participation in extracurricular programs and the failure to develop their talents and interests. Therefore, a decision support system is needed to accurately recommend extracurricular activities based on each student's potential. This study aims to design and develop a recommendation system using the Multi-Criteria Decision Making (MCDM) approach, specifically the Elimination and Choice Translation Reality (ELECTRE) method. This method is capable of selecting the best alternative from several options based on specific criteria. With the implementation of this system, the school is expected to provide more accurate and appropriate recommendations for extracurricular activities, thereby supporting students in achieving their full potential and academic success.

Abstract

− CV D'Lantik Art Project is a company engaged in the art industry, especially in providing decorations for events in malls, hotels, and other public places. In its operational process, the recording of goods is still done manually using Microsoft Excel, which often causes delays in reporting and potential recording errors. Along with the development of technology, the implementation of a web-based inventory system is an important solution to improve efficiency and accuracy in managing stock items. This internship aims to design and develop a web-based inventory system with barcode scanning features using the Agile development method. This method was chosen because of its flexibility and iterative approach in planning, implementing, testing, and maintaining the system. The result of this activity is an inventory website that can help companies in recording incoming and outgoing goods more efficiently and in real-time. It is hoped that this system will be able to reduce human error and increase the effectiveness of stock monitoring to support the company's project needs.

Abstract

In an increasingly saturated smartphone market, brand differentiation through technical specifications has become a core strategy for attracting diverse consumer segments. This study proposes a machine learning approach to uncover underlying brand strategies by leveraging smartphone specifications and market pricing across multiple regions. We utilize unsupervised clustering algorithms (K-Means, DBSCAN) to segment devices based on technical features, followed by supervised classification models (Random Forest, XGBoost) to identify and interpret brand-driven design strategies. The dataset comprises smartphones released in 2024–2025, including attributes such as RAM, camera specifications, processor type, battery capacity, and launch prices in Pakistan, India, China, USA, and Dubai. Our findings reveal distinct clusters that align with different pricing tiers and show clear brand positioning patterns. Feature importance analysis using SHAP highlights battery capacity, screen size, and processor type as critical variables influencing brand classification. This study provides valuable insights for both manufacturers and consumers in understanding competitive product strategies within the global smartphone market.

Abstract

Ibay Computer is a Course and Training Institute that focuses on Computer Technology. This institution requires teachers who are qualified and professional in their fields, however, the process of recruiting teachers at the institution has so far not been effective and does not have good standards, which has caused the institution to experience ups and downs in the number of students. Based on these problems, to help institutions, a Decision Support System is needed with support using the Preference Selection Index (PSI) Method. This system is designed to assist decision making in solving problems by sorting the highest ranking values ​​to provide decision recommendations. The decision support system for recruiting new Ibay Computer Rantauprapat teachers using the PSI method can be implemented well and has very good performance when seen from the results of accuracy testing. By applying the PSI method, Nurmayana Sari will receive the highest ranking as a computer teacher with a total score of 1,000.
