Abstract

Education is one of the means to create and improve the quality of better human resources. This is expected to improve human welfare. Based on data from the Ministry of Education and Culture, there are 4 sub-districts in Karawang Regency that do not have state high schools. This can result in difficulties for students who have financial deficiencies which can ultimately lead to dropping out of school. Then apart from that distance can also be an obstacle. The purpose of this study is to apply the clustering method for the distribution of educational supporting factors in Karawang District so that later this research can improve the quality of education evenly in Karawang District, not only concentrated in certain areas by paying attention to educational supporting factors. The algorithm used in this research is K-Means. The elbow method used in determining the optimal cluster supported by the silhouette method resulted in the best number of clusters being 2 clusters. The results of the clustering evaluation resulted in Davies-Bouldin Index (DBI) value of 0.408 and Silhouette Coefficient value of 0.747 (strong structure). Cluster 1 consists of 7 sub-districts and Cluster 2 consists of 23 sub-districts. Based on the results of clustering analysis, Cluster 1 has the average number of attributes of schools, teachers, classes, laboratories, libraries at all levels of education (SD, SMP, SMA, SMK, and SLB) with state status and the population shows higher results if compared with the average number of each attribute in Cluster 2. So it can be concluded that Cluster 1 is a high category and Cluster 2 is a low category.

Abstract

Every year the area of paddy fields in Karawang Regency has increased and decreased due to land conversion. Climate change also causes changes in the amount of rain and rain patterns that cause shifts in the beginning of the season and the planting period. If the decrease in planting area will be affected, then the price of rice will increase and farmers will maintain the area and not convert their rice fields to function, therefore a study was conducted to predict the rice planting area in order to know the description of the area of rice planted in Karawang Regency will increase. , decreased or stabilized. So the search for information on the data on the area of rice planting in Karawang Regency was carried out. A total of 180 data were processed using data mining techniques so that they could mine information from the data. Data mining is a technique of extracting or new discoveries from large data and then extracting the data into information that can later be used. Experiments were carried out using the CART algorithm and cross validation using the Weka tools. The results of the evaluation carried out can be concluded that the CART algorithm using different K values provides different evaluation results. The performance of the algorithm is seen from the accuracy, precision, recall and F-Measurement, thus providing different performance values for each result. The value of k=8 has the highest accuracy value, which is 90% with precision 0.918%, recall 0.906% and F-measure 0.949%.

Abstract

This study focuses on the field of Human Computer Interaction (HCI) and aims to evaluate the usability level and redesign the user interface of the SMAN 1 Karawang website to improve user experience. The problem addressed is the low level of usability, as indicated by unclear navigation, unstructured layout, and inconsistent interface design. Based on the initial evaluation using the System Usability Scale (SUS) involving 20 respondents, an average score of 61.625 was obtained, indicating that the system was still in the marginal category. The methods used in this study are the System Usability Scale (SUS) for usability evaluation and the User Centered Design (UCD) approach for the redesign process. The results show that after the interface redesign, usability improved significantly and reached the acceptable category. Therefore, the implementation of SUS and UCD methods is proven to be effective in improving usability and user experience on the SMAN 1 Karawang website.

Abstract

Website sekolah yang intuitif dan responsif sangat penting untuk memudahkan akses informasi bagi siswa, orang tua, dan masyarakat. Penelitian ini mengevaluasi antarmuka pengguna (UI/UX) website SMK Widyanusantara Bekasi menggunakan metode heuristik dan kuesioner, kemudian merancang ulang tampilan berdasarkan prinsip desain responsif dan kebutuhan pengguna. Hasil evaluasi awal menunjukkan masalah navigasi, inkonsistensi desain, serta kesulitan penggunaan yang menghambat user experience. Dengan menerapkan siklus User Experience (analisis, desain, implementasi, evaluasi), dilakukan uji kegunaan (usability test) yang mengukur keberhasilan tugas, waktu pengerjaan, dan kepuasan pengguna. Redesain menghasilkan peningkatan performa: tingkat keberhasilan tugas naik dari 65% menjadi 90%, waktu rata-rata tugas turun dari 60 detik menjadi 45 detik, dan skor kepuasan (SUS) dari 60 menjadi 80 (Tabel 1). Hal ini menunjukkan bahwa perbaikan UI/UX yang disertai desain responsif dapat meningkatkan efisiensi, efektivitas, dan kepuasan pengguna.
