Conventional document collection by applicants can lead to the loss of documents, and there is no method in the selection of training providers, resulting in frequent occurrences of sole providers and difficulties in choosing providers for specific training needs. The research has led to the development of a web-based system using the Profile Matching method. The Profile Matching method was chosen because it involves determining competency values (standard assessment criteria) required for specific types of training, serving as a reference to evaluate selected provider candidates. This method selects the best alternative from various options by comparing the individual competencies of providers with the desired training profile values, resulting in competency differences (Gains Across Product). The smaller the GAP, the higher the weight of the score generated. Providers with the highest score have the highest ranking and a greater chance of being selected as training instructors at PCU. Data collection techniques used include observation and interviews.</em></p> Ahmad Zaki, Rahmi Fauzana Copyright (c) 2024 Digital Zone: Jurnal Teknologi Informasi dan Komunikasi http://creativecommons.org/licenses/by-sa/4.0 https://journal.unilak.ac.id/index.php/dz/article/view/16679 Wed, 01 May 2024 00:00:00 +0000 Implementation of the Linear Regression Method to Determine Predictions of the Influence of Religion on General Election Participation https://journal.unilak.ac.id/index.php/dz/article/view/18105 <p><em>This research aims to predict election participation in places of worship through statistical data analysis methods and predictive algorithms. Election participation, as a complex phenomenon, is influenced by various factors, with religion often being a crucial element that motivates or inhibits voter turnout. This study uses variables from Central Statistics Agency (BPS) data and recapitulation of previous general elections, based on historical patterns. Using a statistical approach, the relationship between religious variables and the level of voter participation in places of worship is identified. The linear regression method is used to predict the influence of religion on election participation. In this research, a series of scenarios were carried out, and the research results showed different variations in R-squared (R-Square) and Mean Squared Error (MSE) results. The best scenario, namely the R-squared scenario with a value of around 0.00012 and an MSE of 0.09934, highlights the potential relationship between religion and voter participation. These findings suggest the need for further considerations in this context, as well as demonstrating the need for model adjustments to improve the accuracy of future election predictions.</em></p> Saniya Izza fitria, Arif Senja Fitrani, Ade Eviyanti Copyright (c) 2024 Digital Zone: Jurnal Teknologi Informasi dan Komunikasi http://creativecommons.org/licenses/by-sa/4.0 https://journal.unilak.ac.id/index.php/dz/article/view/18105 Mon, 06 May 2024 00:00:00 +0000 Public-Private Collaboration to Overcome the Digital Divide in Digital Transformation of Government https://journal.unilak.ac.id/index.php/dz/article/view/17027 <p><em>The objective of this article is to explore the issue of the digital divide and how we can bridge it to overcome the challenge of digital transformation.

The resulting images often exhibit heterogeneous intensity distributions, with boundaries not always distinctly clear between the tooth roots and bone, along with variations in shape and pose. This study specifically aimed to identify the optimal image for segmenting specific parts of the dental structures. Image segmentation is crucial for ensuring effective diagnosis in the context of dental medicine. To achieve optimal dental image segmentation, this research combines edge detection methods with the determination of color thresholds, specifically grayscale and Hue, Saturation, Value (HSV). The research findings revealed that edge detection using the Sobel gradient operator yielded a relevant count of 17,099 pixels. Using RGB=3 and HSV=0.3 the color thresholds show an enhancement in the brightness of the resulting HSV-segmented image, while in the RGB-segmented image, the selected object appears more prominent. The findings of this study contribute significantly to the evolution of dental image segmentation techniques, potentially enhancing the accuracy and effectiveness of diagnoses within the realm of modern dental practice</em></p> Susandri Susandri, Sumijan Sumijan , Ahmad Zamsuri , Rahmiati Rahmiati, Asparizal Asparizal Copyright (c) 2024 Digital Zone: Jurnal Teknologi Informasi dan Komunikasi http://creativecommons.org/licenses/by-sa/4.0 https://journal.unilak.ac.id/index.php/dz/article/view/18757 Fri, 31 May 2024 00:00:00 +0000 Optimizing Arowana Fish Breeding with IoT Aquaculture https://journal.unilak.ac.id/index.php/dz/article/view/13896 <p><em>Monitoring and controlling water temperature and pH levels are crucial aspects in maintaining a healthy environment for breeding Arowana fish.
