Abstract

In the contemporary era, technological advancements have significantly impacted various aspects of human life, offering increased efficiency and convenience. Indonesia, aiming to enhance international competitiveness, recognizes the importance of integrating technological innovation across economic sectors. Despite its abundant natural resources, Indonesia's vital agricultural sector faces challenges, including the limited adoption of modern technology, resulting in suboptimal productivity. This study focuses on addressing these challenges by developing the MyHydro mobile application, utilizing IoT and Progressive Web App (PWA) technology to enable remote monitoring and control of hydroponic systems. The research methodology includes literature review, user requirement analysis, system design, and black-box testing. Results show that MyHydro successfully bridges the gap between traditional farming practices and modern technology. Users can efficiently monitor and control hydroponic systems, enhancing crop yields and promoting sustainability in Indonesian agriculture. In conclusion, MyHydro offers a valuable solution to modernize Indonesian farming, aligning with global trends in smart agriculture.

Abstract

Rose of Sharon Church (ROSC) Salatiga, as a rapidly growing spiritual community, faces challenges in managing the increasing number of congregants, especially during events and compliance with health protocols. This significant growth necessitates more effective attendance management to avoid overcrowding. This research addresses this need by developing the ROSC Worship Reservation application based on Progressive Web Apps (PWA) using the Flutter Framework. The application aims to simplify congregants' worship reservations, reduce crowds, and support church administrative tasks. The use of Flutter as the primary framework provides advantages in rapid development and a user-friendly interface. The results of the User Acceptance Test (UAT) show a high satisfaction rate, reaching 92%, regarding the application's functionality and user interface. Additionally, 84% of respondents state that the seating layout displayed by the application significantly aids in effectively choosing seats. It is hoped that the application will continue to provide benefits in managing congregational attendance systematically, efficiently, and in compliance with health protocols. The conclusion of this research emphasizes that the ROSC Salatiga Worship Reservation has successfully created an innovative solution to support church management amid the dynamic growth of congregational attendance.

Abstract

Purpose: This training for social media content creators and professional video production techniques is conducted with the aim of providing motivation and insights into the tricks and techniques needed to become a content creator. The goal is for the participants, who are high school students, to utilize their gadgets and time more constructively rather than for consumptive purposes. Methodology: Organized by the Information Systems Department of Atma Jaya Catholic University of Indonesia, this training will be held at Campus 3 BSD Unika Atma Jaya on Saturday, November 25, 2023. Targeting 60 to 100 high school students from Banten, the activity will be evaluated using pre-tests and post-tests, calculated manually using the average formula. Results: The result of the training activity went smoothly and achieved the initial target of being attended by 90 active participants. The selection of speakers for the training was also appropriate, matching their expertise, and they were able to deliver the material clearly using various real-life examples. The evaluation results of the activity showed that the post-test scores increased by 43.7% compared to the pre-test scores. Therefore, it can be concluded that the participants understood what was conveyed by the speakers. Conclusions: The right resource persons and interactive learning methods contributed to the effectiveness of the training. The success of this activity shows a positive impact in increasing the creativity and productivity of the younger generation in utilizing gadgets constructively. Limitations: Due to time and budget constraints, the activity was not conducted with direct hands-on practice in the form of a workshop. Additionally, the target participants were limited to the surrounding area, specifically high school students in the Banten region. Contribution: This training gives high school students broader insights, enabling them to use their gadgets and time positively. It also equips them to become content creators by learning professional video production and social media management skills.

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. Salah satu sekolah ternama yaitu SMAK 7 Penabur Jakarta telah menerapkan teknologi dalam proses pengajarannya sesuai dengan visi dan misi sekolah. Pada tanggal 9 dan 10 November 2023 sekolah tersebut menggelar kegiatan Workshop IT Camp yang dimana salah satu dosen dari prodi Sistem Informasi Universitas Katolik Indonesia Atma Jaya (Unika Atma Jaya) ikut berpartisipasi sebagai narasumber.

Seluruh rangkaian kegiatan ini dilakukan dengan tahapan persiapan, pelaksanaan, dan evaluasi. Narasumber berhasil melaksanakan kegiatan edukasi pengenalan dasar web design di SMAK 7 Penabur Jakarta yang dihadiri oleh 21 peserta siswa-siswi SMA dari kelas X, XI, dan XII dengan baik dan tanpa kendala yang serius.
