Abstract

Enterprise resource planning (ERP) software systems such as SAP S/4HANA may have problems with storage efficiency‚ latency‚ and data resilience when deployed in a public cloud? Hybrid and multi-cloud infrastructures allow organizations to utilize on-premise infrastructure on-site in combination with a distributed public cloud infrastructure for improved performance‚ cost‚ and regulatory compliance? This paper introduces a workload-aware storage framework for SAP S/4HANA migration across hybrid and multi-cloud environments? It proposes a three-level architecture for clever data-tiering based on the classification of access patterns‚ adaptive workload placement based on SLA constraints‚ and cross-cloud orchestration with multi-objective optimization of storage cost‚ access latency‚ and operational risk in SAP system migration? Evaluation with large-scale synthesized SAP workloads matching published transactional‚ analytical‚ and archival access patterns shows a reduction in storage cost by up to 34%‚ reduction in access latency by up to 28%‚ and a more reliable system under simulated provider failure patterns‚ compared to static single-cloud and hybrid baselines? We find that storage-layer optimization is an important and under-explored dimension of enterprise cloud transformation strategy?

Abstract

Semiconductor manufacturing equipment demands deterministic real-time control architectures capable of synchronizing multi-axis motion, power delivery, and process sensing within microsecond-level timing windows to achieve the precision required at advanced technology nodes. EtherCAT, an industrial Ethernet protocol designed for hard real-time fieldbus communication, provides the deterministic, low-jitter communication fabric necessary to meet these stringent timing requirements across distributed embedded control nodes. This paper presents the design and implementation of an EtherCAT-based control architecture for high-precision semiconductor manufacturing systems, with a specific focus on RF impedance matching control deployed on a heterogeneous system-on-chip platform integrating the Xilinx Zynq-7000+ SoC. The proposed architecture implements a precision closed-loop control system that dynamically regulates RF voltage by actuating variable capacitors via stepper motor drivers with optical encoder feedback, enabling deterministic EtherCAT-controlled, synchronized, and independent actuation modes across multiple control axes. The Zynq-7000+ platform leverages its heterogeneous processing architecture — combining ARM Cortex-A9 application processors with FPGA programmable logic — to implement time-critical EtherCAT slave communication and closed-loop control algorithms in hardware while managing higher-level coordination logic in embedded software. Experimental results demonstrate sub-microsecond cycle-time repeatability, RF voltage regulation accuracy within 0.5% of the setpoint, and stable closed-loop tracking performance under dynamic impedance load variations representative of plasma etch and deposition process conditions. The architectural principles and implementation methodology established in this work provide a replicable framework for deploying deterministic EtherCAT-based control in semiconductor process equipment requiring distributed, high-precision motion and power regulation.

Abstract

This study examines the typology of old houses in Kampung Arab Tanjung Selor, Bulungan Regency, North Kalimantan, a historic Arab settlement dating back to the 19th century. This settlement has historical value and unique old buildings, whose condition is deteriorating due to rapid development, requiring preservation efforts. Therefore, this study aims to identify and classify the typology of old residential buildings in Kampung Arab to support its development as a cultural heritage area. The method used is a qualitative descriptive, typological approach, in which data are collected through field observations, interviews with community leaders and elders, and documentation. The objects of study were three old houses believed by local community leaders to have been built during the arrival of the Arabs in Tanjung Selor, namely the houses of Salim bin Djoemaan, Umair Al Hasyim, and H. Muhamad Bansir, all of which are more than 100 years old and still retain their original structures. The results of the study show that these old houses share architectural similarities with Malay architecture and adopt the stilted structure of Kalimantan vernacular architecture as an adaptation to the swampy environment. The house's floor plan is rectangular, symmetrical, and clearly divided into public zones (veranda, living room), private zones (family room, bedrooms, dining room), and service zones (kitchen, bathroom). The separation of these spaces demonstrates the high value placed on privacy. Overall, these old houses embody Islamic values such as efficiency, egalitarianism, privacy, and local wisdom.

Abstract

Fisheries-based food security in underserved coastal villages remains vulnerable due to limitations in fishing capacity, rising fuel costs, environmental degradation, and restricted access to modern fishing technologies. These challenges significantly affect the productivity and income of small-scale fishers, ultimately influencing the availability and affordability of fish as a primary source of protein for coastal communities. In many coastal areas of Indonesia, particularly in underserved villages, conventional fishing activities continue to rely heavily on fossil-fuel-powered boats, resulting in high operational expenses and increased greenhouse gas emissions. Consequently, there is a growing need for innovative and sustainable technological solutions that can improve fisheries productivity while supporting environmental conservation and community welfare. This study presents the design, development, and application of an autonomous, solar-powered small fishing boat aimed at enhancing sustainable fisheries production in underserved villages in Demak Regency, Indonesia. The proposed system integrates renewable energy harvesting through photovoltaic panels, autonomous navigation technology, fish location sensing, and intelligent route optimization to reduce dependence on fossil fuels while increasing operational efficiency and fishing effectiveness. A mixed-method approach was employed, combining engineering design, prototype development, laboratory validation, field deployment, and pilot testing involving local fishers. Stakeholder feedback was also collected to evaluate usability, acceptance, and potential socioeconomic impacts. The results indicate that the solar-powered autonomous fishing boat reduces operational fuel costs by approximately 95%, increases fishing efficiency by 42%, and decreases greenhouse gas emissions by an estimated 1.8 tonnes of CO? per vessel annually. Furthermore, the system demonstrates reliable navigation performance and contributes to safer fishing operations by reducing human workload and optimizing fishing routes. The adoption of this technology has the potential to increase fisher income, strengthen local food security, and support sustainable fisheries management. This innovation aligns with national strategies for renewable energy utilization, blue economy development, and rural economic empowerment, offering a scalable and environmentally friendly solution for coastal regions facing similar socioeconomic and ecological challenges.

Abstract

This study aims to develop and evaluate a deep learning-based mobile application for the automated classification of ornamental plants, addressing challenges associated with visual similarity among species and environmental variability during image acquisition. The proposed system utilizes a Convolutional Neural Network (CNN) based on the MobileNetV2 architecture, selected for its lightweight structure and deployment efficiency on resource-constrained mobile devices. The dataset comprises approximately 600 images representing 10 ornamental plant classes, collected from real-world environments, and processed through a standardized preprocessing pipeline. Model training was conducted using the Teachable Machine platform over 100 epochs, with a batch size of 16 and a learning rate of 0.001, allocating 90% of the dataset for training and 10% for testing. Experimental results indicate that the proposed model achieves a classification accuracy of 96.3%, corroborated by evaluation metrics including accuracy curves, loss convergence, and class-wise performance analysis. The trained model was successfully converted into a lightweight format and integrated into an Android-based mobile application developed using the Flutter framework. Functional testing demonstrates that the application performs effectively in real-time classification scenarios, maintaining high accuracy and responsive on-device inference without relying on cloud computing. In conclusion, this study confirms that lightweight deep learning architectures, such as MobileNetV2, can be effectively implemented in mobile environments for ornamental plant classification. The proposed application enhances accessibility and usability, enabling rapid and accurate plant identification. Furthermore, this approach contributes to practical applications in horticulture, education, and biodiversity awareness, while demonstrating the feasibility of deploying efficient deep learning models on mobile platforms.
