Abstract

Batik Besurek is an Indonesian cultural heritage that presents a variety of motifs reflecting the richness of creativity and symbolic meanings. A significant challenge in this field is accurately and efficiently identifying and classifying batik Besurek motifs, known for their intricate designs and cultural significance. In efforts towards cultural preservation and development, a combination of modern technology and local wisdom is required. One technology that can be utilized is object detection technology using You Only Look Once (YOLO), specifically the latest version, YOLOv8, for the classification of batik Besurek motifs. The dataset collected consists of 1,656 images taken from the Roboflow public repository, containing various motifs such as Burung Kuau, Kaligrafi, Kembang Melati, Rafflesia, and Rembulan. The dataset is divided into 1,324 images (80%) for the training set, 166 images (10%) for the validation set, and 166 images (10%) for the test set. Model training is conducted with hyperparameter values: learning rate of 0.01, batch size of 16, and 100 epochs. The application of the YOLOv8 model as a training model for the batik Besurek motif dataset yields an accurate final model with an average precision value for each motif class of 96%, and an average recall value for each motif class of 93%. This study aims to assist communities in recognizing and distinguishing batik Besurek motifs, contributing to the preservation of Indonesia’s cultural heritage.

Abstract

Sebagian besar lembaga pendidikan telah melakukan upaya nyata untuk memajukan kecerdasan bangsa dengan menerapkan penggunaan teknologi khususnya komputer dalam kegiatan belajar mengajar.

Abstract

Gereja Isa Almasih Jemaat Purwodadi dengan jumlah jemaat yang terus bertambah dan kegiatan ibadah yang beragam, menimbulkan tantangan bagi pengurus gereja dalam mengelola semua aspek administrasi dan penjadwalan dengan efisien.

Abstract

The quality of education needs to be observed and maintained in building an effective teaching and learning environment. There are several factors that can affect the quality of education in a school, such as the availability of human resources, supportive learning facilities, environmental conditions, and various other factors. The focus of this research is on the ideal number of teachers in a school, considering the number of students and the availability of facilities such as laboratories and libraries, which will be correlated with the failure to pass the class rate. Data were obtained from the official website of the Kemdikbudristek regarding educational statistics, comprising 29 districts in Tangerang Regency for the academic year 2023/2024 at the senior high school level. The analysis was conducted using multiple linear regression, and it was found that the variables "availability of laboratory" and "availability of library" did not correlate with the failure to pass the class rate, whereas the "teacher ratio" variable correlated with the failure to pass the class rate with a value of +0.46. This can be explained that for every increase of 1 unit in the teacher ratio variable, or in other words, the fewer teachers teaching in a school compared to the number of students, the failure to pass the class rate will also increase by 0.46 students. Therefore, the results of this research can provide input for schools, especially in Tangerang Regency, to pay attention to the number of teachers in each school.

Abstract

The rapid advancement of information technology has significantly impacted various sectors, including public service. The Indonesian government's M-Paspor application, designed to streamline the passport application process, has faced several user experience challenges, such as complicated registration processes, inaccurate location selection, and difficulty in finding queue schedules. This study aims to analyze and redesign the M-Paspor application using the Design Thinking method, a user-centered approach involving empathy, problem definition, ideation, prototyping, and testing stages. Through a thorough literature review and usability analysis, we identified key issues affecting the application's performance based on four usability indicators: learnability, efficiency, errors, and satisfaction. The redesigned interface, developed using the Design Thinking framework, addresses these issues by improving clarity, navigation, and overall user experience. Our findings indicate that the redesigned M-Paspor application significantly enhances user satisfaction and efficiency, ultimately supporting the government's vision of effective and efficient e-governance. This study not only provides practical solutions for improving the M-Paspor application but also offers insights into the application of Design Thinking in public service technology design.
