Abstract

Agriculture in Bali generally using Subak system as an irrigation system. This irrigation system is regulated by a traditional leader who is also a farmer in Bali. Water distribution is carried out according to the area of farmers land. The problems that can be happened on this irrigation system, such as the community that opens the floodgates to the rice fields, are not in accordance with the time provided by traditional leaders, and that can break the unity in the area. In addition, during the dry season the distribution of water is sometimes uneven because the availability of water in the dam does not meet the needs. So that Arduino-based Solar Powered Smart Irrigation is designed as one of the tools to facilitate the management of subak water distribution. The modeling made is to simulate 3 pieces of rice fields that are drained by water with the main source being the river and the source of the reserve in the form of a reservoir. This system is controlled based on the programmed time on the RTC module and the monitoring system uses the GSM SIM900 module. The data obtained is the value of water discharge in the rainy season of 2.090 L / s, the dry season of 11.18 L / s, and 0 L / s in the hard dry season.

Abstract

Perkembangan teknologi jaringan yang pesat telah mendorong lahirnya arsitektur Software Defined Network (SDN) yang memungkinkan mengatur dan mengontrol jaringan melalui perangkat lunak terpusat. Dengan SDN, administrator jaringan dapat mempercepat koneksi dan mengelola lalu lintas jaringan dari satu lokasi pusat tanpa harus mengakses perangkat keras secara langsung. Openflow adalah protokol komunikasi yang memungkinkan pengawasan dan kontrol penuh terhadap jaringan. Urgensi dari penelitian ini terletak pada kebutuhan untuk menentukan jalur terpendek secara efisien dalam SDN agar mendapatkan performa jaringan yang terbaik. Algoritma Dijkstra sering digunakan dalam SDN untuk menentukan jalur terpendek, namun Algoritma Floyd-Warshall juga dapat digunakan dengan pendekatan pemrograman dinamis. Penelitian dilakukan untuk membandingkan kedua algoritma ini dalam memperoleh jalur terpendek pada SDN. Metode yang digunakan yakni pertama, Algoritma Floyd-Warshall diubah menjadi Algoritma Dijkstra pada controller. Kemudian, dibangun tiga skema topologi jaringan menggunakan mininet, masing-masing terdiri dari dua host (host awal dan tujuan), satu controller, dan beberapa switch. Pengujian dilakukan pada controller dengan algoritma berbeda menggunakan tools POX pada tiga skema topologi jaringan. Pada penelitian ini diperoleh untuk mendapatkan jalur terpendek pada SDN, Algoritma Dijkstra terbukti lebih unggul dibandingkan Algoritma Floyd-Warshall. Dengan ini menunjukkan bahwa pemilihan algoritma yang tepat pada controller SDN dapat meningkatkan efisiensi jaringan.

Abstract

Abstract— Bali is one of the provinces with quite complex cultural diversity in Indonesia. One of them is the characterization of traditional masks. Traditional masks in Balinese tradition are not only intended as performance accessories, but also as symbols of characterization, social status in indigenous communities, rites, and certain primordial activities. Every detail in the curve of the carving on the Balinese mask indicates an aesthetic richness that is certainly measurable as an ontological entity. In this case, the magnitude of this aesthetic measurability can be assisted by using various computational methods. This study tries to create a machine learning model with supervised learning to create a classification system for Balinese mask characterization. The methods used include: processing mask images into a 3-dimensional vector, each representing the red, green and blue color indices. Then each vector will go through a training process to create a measurability model for each characterization. The models used are EfficientNetV2 and Xception which are developments of convolutional models. The performance measurement metrics used are Accuracy, Precision, Recall & F1-Score. The Xception model produced an accuracy of 97%, while the EfficientNetV2 model produced an accuracy of 99%. Keywords— Bali, Classification, EfficientNetV2, Mask, Xception

On July 9, 2024, the Computer Engineering Faculty at Warmadewa University conducted a Community Service Program titled "TERAS Digital Peguyangan Kaja," which involved outreach and training to maximize the use of electronic signatures, evaluated using SWOT analysis. This program offers benefits such as the effectiveness and efficiency of public services. The implementation of electronic signatures is hindered by infrastructure issues and social resistance, necessitating outreach, intensive training, and infrastructure improvements. This community service program, in collaboration with the Denpasar City Communication and Information Agency (Diskominfo). This activity involved 25 participants consisting of village officials and service implementers, as well as representatives from the Denpasar City Communication and Information Office (Diskominfo). The evaluation of activities was carried out using SWOT analysis, involving socialization, training, and mentoring to implement the use of electronic signatures. evaluation using SWOT analysis. The implementation of socialization and training has increased the digital literacy of the community and village officials, increasing efficiency and effectiveness in solving the problems of the people of Peguyangan Kaja Village when the party whose signature is required by the village apparatus is in the way. .

Abstract

Bali, with its rich culture and diverse symbolism reflected in the traditional fabric motifs. However, the manual recognition of Balinese fabric motifs faces challenges such as pattern complexity, similarity between motifs, and limited public knowledge. This study aims to address these challenges by using Artificial Intelligence (AI) to automate the process of accurately and efficiently identifying Bali fabric motifs. The research develops a motif recognition model for Bali fabrics using Inception V3 and EfficientNet B1 algorithms in image classification analysis. The research methodology used is experimental, starting with dataset collection, data augmentation, feature extraction, modeling, and testing. The results show that the EfficientNet model achieved an accuracy of 99% on the 25th iteration, much higher than Inception V3, which only achieved 62% accuracy. These results indicate that the EfficientNet model is more effective in recognizing and classifying Bali fabric motifs and strengthen the potential of artificial intelligence in cultural preservation.Keywords: Bali; Classification; EfficientNet; Inception; Pattern AbstrakBali, dengan kekayaan budaya yang kompleks serta beragam simbolisme.

Abstract

The construction industry is renowned for its hazardous nature, with a significant number of accidents occurring annually. These accidents result in serious consequences, including costs for disability benefits, decreased worker productivity, and idle equipment, hindering development. To address these challenges, safety must be a priority during the construction planning stage. Occupational Health and Safety (OSH) programs play a crucial role in ensuring worker safety and health. Building Information Modeling (BIM) has emerged as a technology that can significantly improve safety in construction projects. BIM provides detailed information and visualizations that help identify potential hazards and develop effective mitigation strategies. However, its implementation in Indonesia is still limited to level 1 BIM, primarily involving 2D and 3D CAD drafting. To enhance 3D building visualization and safety planning, this paper proposes integrating BIM with three.js and ReactJS. Three.js is a JavaScript library that enables the creation of 3D visualizations in web browsers, while ReactJS is used to build user interfaces in web applications. By combining these technologies, interactive web applications can be developed to display 3D buildings in real-time. This allows users to easily view building designs, identify potential hazards, and make informed decisions regarding safety measures. Furthermore, the Industry Foundation Classes (IFC) file format is utilized for data exchange in the BIM environment. IFC contains building geometry information, material properties, and other relevant data, enabling collaboration among project teams using different software. This integration enhances collaboration and facilitates more informed decision-making in construction projects. The results demonstrate efficient 3D rendering of BIM models with an average response time of 0.8 seconds, as well as real-time visualization of worker positions within buildings based on sensor data.
