Abstract

Progress in various fields of technology, especially advances in information technology and computers, encouraging the emergence of new innovations in the presentation of information to meet the needs of information. As a tool of man, the computer also has advantages such as speed, accuracy and efficiency of data processing as compared to manual systems. In the case of SMAN 1 Matur still many systems are still done manually, including the majors interests of students, where the weaknesses of the current system is the amount of use of paper for printing questionnaires charging interest and talent for each student. Long process of distribution of questionnaires from teachers to students, after students filled in questionnaires, the questionnaire must be returned to the teacher to be processed in order to get the interest and talent, only then accepted by the students. Thus it will be in designing a new system of student data processing system before using the questionnaire into a web-based application that can encapsulate student data thus simplifying the decision granting the interest and talent of students of SMAN 1 mature.

Abstract

This study aims to automatically classify rice field and oil palm land cover based on aerial imagery by utilizing the Gray Level Co-occurrence Matrix (GLCM) for texture feature extraction and the K-Nearest Neighbor (KNN) algorithm as the classification method. The dataset consists of 130 training images and 111 test images. The images were processed through cropping and grayscale conversion, followed by texture feature extraction including contrast, correlation, energy, and homogeneity. These features serve as the foundation for distinguishing the unique texture patterns of each land type. The test results show that the K parameter in KNN significantly affects the classification accuracy, with K=7 achieving the best result of 97.30%. Evaluation using a confusion matrix reinforces the effectiveness of the method in distinguishing the two land cover classes. The combination of GLCM and KNN proves to be both efficient and accurate, with great potential to be applied in automated mapping and monitoring systems, particularly in agricultural and plantation contexts.

Abstract

The important role of a computer in work activities is solving cases that require fast and precise computing processes. However, the limitations of the required computer specifications must sometimes be taken into account according to the specified needs. Cases that are commonly found in terms of aspects of the availability of computer specifications are related to multimedia, and one that is quite prominent in the current 4G technology trend is e-sport activities, namely online games. The main requirement for running games is video-memory capacity, namely image requirements. The image is based on a dictionary-color data that can be saved, so for a display with fidelity characteristics it certainly requires a large video-memory capacity, so that when the game is running it doesn't get stuttering. A fairly simple method with a decision-tree approach by applying certain techniques or algorithms, in order to obtain the specifications of the computer; based on the component attributes it has (such as processor, main-memory, and video-memory), and the operating system (such as software) is whether it is compatible or vice versa. There are two operating systems involved in the testing process, namely: Windows 10 and Windows 11; the Windows family was chosen for the reason that the majority of users use it and is adapted to games that are commonly run on this variant of the operating system. The decision tree approach is based on the C4.5 algorithm. And in this research a series of tests have been carried out on a number of computers with various characteristics and specifications; with the field of objects tested being games, without specifically limiting whether they run on-line or off-line; but on this research used on-line . There were three sample games involved in the testing with the number of computers processor being selected using seven different specifications. The results show that from a number of computer specifications involved in testing the three game samples, some are compatible. And the results obtained showed that the machine learning model designed was optimal.

Abstract

Micro, small and medium enterprises (MSMEs) are one of the pillars of the current economy because they help the community and increase employment opportunities. MSMEs usually only reach an area, so if the area's MSMEs are developed then the surrounding community will also prosper, and vice versa. Even though it is only MSMEs in a region, it does not rule out the possibility of selling products/services to other regions or even abroad, one of which is by utilizing online-based sales. However, for food products, buyers usually prefer to go directly to the shop compared to ordering online because it takes time and there is a risk of damaged packaging and so on. Good sales are inventory that is always available and measurable both in offline and online sales. Therefore, the form of this system is to present information from data on the number of product sales using the Monte Carlo simulation method in the MSME industry of XYZ shop, the aim of which is to predict income and inventory of goods from sales of each product for the following month. In essence, this system is designed to predict gross profit on each type of item in the store. With this system, it is hoped that it can be used by the MSME industry to simulate the sale of goods in shops, and can make it easier for MSME industry owners to obtain information about the possibilities that will occur in the sale of their products.
