The consumption profile of electrical energy always increases every year due to the highly consumptive and inappropriate lifestyles of modern society. A bad lifestyle such as forgetting to turn off the unused electronic devices when they are leaving home is one of the factors influenced the increasing consumption of electrical energy. This is off course contributing in wasting energy. In the paper, an IoT-based electronic device control system has been successfully constructed. Monitoring and control tasks could be performed remotely and in real time mode using an interface application installed on a smartphone. The system built is equipped with a device operational condition monitoring featured by placing light, temperature, thermal and current sensors, respectively. Through the utilization of the implemented system, users can monitor and control electronic devices easily and can figure out the condition of the device remotely in a real time mode. The control test on the system was successful with an average response time of approximately 3.32 seconds and the accuracy of sensor readings above 89%. With the implementation of this system, users can easily monitor and control electronic devices anywhere and anytime so that the opportunities for efficient and effective use of electrical energy could be further optimized. © 2022.

The purpose of this paper is to gift a visualization of three-dimensional (3D) trees using L-System that has been researched before. In this research, he succeeded in making a two-dimensional (2D) tree visualization and stated that when the iteration value or iteration value is larger than five, the 2D tree model results from associate iteration, it lost detail from the branch. This research is to develop the research results, namely the transformation from a 2D tree to a 3D tree. This research is intended to see what is needed in the transformation process from a two-dimensional tree to a three-dimensional tree using the L-System approach. The experiments carried out in three steps, the first step performing a two-dimensional visualization of the grammar origin from the previous research, the second step carrying out a three-dimensional transformation, and the third step making grammar modifications so that the 3D tree becomes realistic. The test results show that mathematically there are differences in the depiction of geometry in the cartesian coordinate with three axes, namely the x, y, and z axes, causing the transformation process from two-dimensional to three-dimensional trees to expand the use of symbols in the L-System. The extended production rules give more complex and more refined geometric shapes. © 2020 IEEE.

This research investigates the adoption of digital twin technology for marine debris management in Bali, focusing on the regions of Denpasar, Badung, Gianyar, and Tabanan. Digital twin technology involves creating virtual models that replicate physical environments and processes, enabling real-time monitoring and simulation. This capability is particularly crucial in Bali, where marine debris presents significant ecological and economic challenges. Digital twin technology offers a strategic advantage by allowing detailed scenario analysis and optimization of management strategies. Using Structural Equation Modeling (SEM), the study evaluates the influence of four key factors within a community resilience framework on the willingness to adopt digital twins: risk perception, planning capability, coping ability, and interest level. The findings suggest that heightened awareness through targeted workshops and campaigns significantly boosts the community's willingness to engage with digital twin technology, highlighting the impact of risk perception. In terms of planning capability, strong processes such as the creation of action plans and task forces are crucial for integrating digital twins into marine debris management strategies. Additionally, robust coping mechanisms, which benefit from access to advanced technologies for real-time response, correlate with a greater readiness to adopt digital twins. Lastly, active community involvement in environmental initiatives indicates a higher propensity to support innovative technological solutions, underscoring the importance of interest level. The study emphasizes the critical role of these factors in creating an environment conducive to the adoption of digital twin technology in Bali. By enhancing these aspects of the community resilience framework, the region can more effectively leverage digital twins to address its marine debris problem. This research offers valuable insights for policymakers, practitioners, and researc

This study aims to determine the best distance to install a CCTV camera in identifying a person's face in the passenger inspection area at the airport, which can be developed for suspect detection systems. The training data used is in the form of an image with five different angles per person, while the testing data is in the form of video. The initial stage conducted is face detection based on local features (a pair of eyes, nose, and mouth) in the input data using the Viola-Jones method. The face detection results process with pre-processing, feature extraction, and classification. In the pre-processing stage, the Brightness Enhancement (BE), Grayscale and Contrast Limited Adaptive Histogram Equalization (CLAHE) methods are used to improve the quality of the detected face. Furthermore, the feature extraction and classification stages use the Histogram of Oriented Gradient (HOG) and the Multi-class Support Vector Machine (MSVM) methods, respectively. The result shows that the best accuracy obtained is 86.76% for a CCTV camera distance of 300 cm and a height of 250 cm. © Published under licence by IOP Publishing Ltd.

Management of breast cancer requires a diagnosis of breast cancer, including an accurate pathology diagnosis to direct the provision of appropriate treatment. Part of inseparable diagnosis of breast cancer itself is determining the presence of metastasis. This study aims to determine the relationship model of pathological diagnosis with the possibility of metastasis to other organs of the breast. Pathology diagnosis results include tumor position, topography, behavior, grade, and tumor status. This study used secondary data from the Hospital Information System (SIRS) of the hospital in Makassar, Indonesia. Data obtained from the results of pathology and clinical examinations of breast tumor as many as 204 patients were hospitalized during the year of 2018. Binary regression analysis modeling was performed to see the relationship between types of pathological diagnosis (laterality, topography, behavior, grade, tumor status) of breast cancer with the possibility of metastases to other organs. The results of the analysis found a significant relationship between the position and status of the tumor with the presence of metastasis. The results of the metastatic binary logistic regression model was L(Y) = 1.330 - 0.670lat1 - 0.779lat2 - 0.724status Chi-square analysis between metastasis with surgery and chemotherapy found the significant relationships between metastasis with surgery (X2 = 15.951;p value = 0.001) and metastasis with chemotherapy (X2 = 20,796;p value = 0.001). The results of this analysis indicate that the position and status of the tumor have a relationship with the likelihood of metastasis. In addition, this metastasis further determines the management of treatment whether surgery or chemotherapy or both. © Published under licence by IOP Publishing Ltd.

Let G be a simple and finite graph with vertex set V and edge set E. The local antimagic total labeling of G is a map from V ∪ E to the set of positive integers from 1 to |V| + |E| such that the weight of two adjacent vertices are distinct. The weight of a vertex v is calculated by the sum of the label of the vertex v and the labels of all edges incident to it. If the vertices of G is labelled by the smallest labels, that is, {1, 2,.., |V|}, then the such labeling is called local super antimagic total labeling. Thus, the local super antimagic total labeling induces a proper vertex coloring of G where the vertex v is colored by the weight of vertex v. The minimum number of colors taken over all colorings induced by super local antimagic total labeling of G, is called local super antimagic total chromatic number of graph G, and denoted by χlsat (G). In this paper, we consider the local super antimagic total chromatic number of some wheel related graphs such as fans, even gear graphs, and sun flower graphs. © Published under licence by IOP Publishing Ltd.

This study examines the decline in the usage of the Javanese language, which has experienced a decrease in the number of speakers from approximately 82 million in 2007 to 68.2 million in 2015. The convergence of the Javanese script and Optical Character Recognition (OCR) technology is proposed as a solution, allowing for the preservation and accessibility of the Javanese script in the digital age. The integration of Convolutional Neural Networks (CNNs) in Javanese script classification achieved a high accuracy rate of 92.95% in identifying positive and negative cases. The dataset used for training consisted of 8440 sample images, which were divided into 20 subfolders for training and testing. The results presented in Table IV demonstrate the successful implementation of the classification model, achieving a 98.87% sensitivity, 100% precision, and 98.88% specificity. This research contributes to the preservation and understanding of the culturally significant Javanese script while addressing the decline in its usage. © 2023 IEEE.
