Abstract

The advancement of information technology (IT) has become essential for organizations, including Bank Mandiri, where it underpins critical business functions. This study examines the implementation of IT governance at Bank Mandiri’s Girian branch using the COBIT 2019 framework, a comprehensive tool for managing IT processes effectively. Through a qualitative case study approach and interviews with key stakeholders, the study analyzes 40 IT processes across 11 design factors, with each factor scored between 75 and 100 to prioritize their importance. High-priority processes, such as Managed Solutions Identification and Build (BAI03), Managed Requirements Definition (BAI02), Managed IT Changes (BAI06), and Managed Projects (BAI11), are identified as critical to operational stability, customer satisfaction, and strategic alignment. These objectives play a fundamental role in resource allocation, supporting seamless IT operations and enhancing customer service. Processes with lower scores are deprioritized, allowing strategic focus on high-impact areas. This prioritization framework helps ensure efficient resource use, aligns IT governance with organizational goals, and reinforces the branch’s commitment to achieving reliable, customer-focused IT management. The study underscores the indispensable role of IT in supporting Bank Mandiri’s operations, where any IT disruption could significantly impact business continuity and customer satisfaction.

Abstract

This study aims to optimize the feature selection process on student complaint data regarding academic services in universities using the Recursive Feature Elimination (RFE) method. Student complaints' diverse and complex nature requires in-depth analysis to identify crucial features that affect service satisfaction. An accurate feature selection process can help universities understand the most frequently reported issues, enabling them to respond and improve services more effectively. The research utilizes complaint data from various aspects of academic services, such as administration, facilities, and faculty interactions. After preprocessing the data to remove noise and irrelevant entries, RFE is applied to select the most relevant features. Subsequently, a classification model is built using the selected features to identify the most significant complaint patterns. Model evaluation is conducted through cross-validation techniques to ensure accuracy and reliability, with metrics such as accuracy, precision, recall, and F1-score. The results demonstrate that the RFE method significantly enhances model performance in selecting essential features, making the classification model more efficient and accurate in predicting student complaints. Thus, this study contributes significantly to assisting universities in enhancing the quality of academic services through a more targeted analysis of student complaints. Implementing this method will improve the complaint-handling process and increase overall student satisfaction

Abstract

This study presents an overview of Ki Hajar Dewantara's constructivism learning theory as interpreted through the system that gave rise to Tut Wuri Handayani. The system places students as the center of the learning process, while the role of the teacher is that of a guide who provides flexibility for children to develop their potential, creativity, talents, and interests according to their nature. Students are not entirely free to seek information and knowledge. Still, guidance from teachers and parents dramatically aids in identifying the nature and form of knowledge children require based on their developmental stage. This aligns with the constructivism learning theory, which suggests that teachers serve as facilitators, motivators, and communicators for their students. This study employs a qualitative approach, analyzing data from literature through an interpretive process to comprehend and provide context for the gathered qualitative data. This study will reveal how Ki Hajar Dewantara's constructivism learning theory compares to other systems. What is the relevance of Ki Hajar Dewantara's constructivism learning theory in the Merdeka Curriculum? The study's results lead to the following conclusions: First, the constructivism learning theory in Ki Hajar Dewantara's system emphasizes the importance of students' Independence in their thinking, the role of teachers as agents of change, the role of teachers as motivators, facilitators, and communicators for students, and the importance of Tut Wuri Handayani. Second, Tut Wuri Handayani illustrates Ki Hajar Dewantara's views on the Merdeka Curriculum through the roles of teachers and students in schools.

Abstract

Workload is a collection of tasks set to be completed within a specific time. The workload can be broken down into "qualitative" (too much or too little) or "quantitative" (too much or too little), which occurs when people are unable to complete tasks or if they do not utilize the abilities they have in achieving a particular job. This study aimed to determine the workload of workers engaged in the sale of fresh or cut chicken meat. Cardiovascular Load is an estimate to determine the classification of workload based on the increase in work pulse compared to the maximum heart rate. The Defense Research Agency Workload Scale (DRAWS) method is a multidimensional technique that involves participants through subjective questions and assessments consisting of four workload dimensions: input demand, central demand, output demand, and time pressure. The results showed that the workload pulse using Cardiovascular Load, the level of fatigue based on workload obtained at the chicken slaughter station by worker 1 was 44.77%, and worker 2 was 41.11% with the category of improvement needed. At the chicken cleaning station, worker 1 was 44.13%, and worker 2 was 47.43%, with the category of needed improvement. At the chicken cutting station, worker 1 was 43.73%, and worker 2 was 45.85%, with the category of needed improvement. The study's DRAWS method results showed that at the chicken slaughtering station, worker 1 was 84.25%, and worker 2 was 87.05% with the overload category. At the chicken cleaning station, worker 1 was 86.75%, and worker 2 was 84.20% with the overload category. At the chicken cutting station, worker 1 was 85.75%, and worker 2 was 81.30%, with the overload category. This means that six respondents felt a high mental burden, so improvements are needed to reduce the impact of the cognitive workload of workers. The upgrades provided include the provision of chairs around the work area, especially at the chicken slaughtering station, so that workers can sit and rest for a moment to reduce the physical workload experienced by workers.

Abstract

The Internet has become a vast repository of information, often filled with distractions that can hinder the user experience. News content, for example, is usually interspersed with advertisements that interrupt the flow of reading. In addition, the fast pace of news publication is also a challenge, with potentially more than 50 new articles appearing in 20 minutes. This high-speed data flow is valuable for various applications, including Social Media Analytics Services. In this context, the speed and efficiency of data acquisition (crawling) and processing (scraping) are critical. These processes must be optimized to ensure comprehensive data collection without gaps, focusing on the latest information. To meet this need, we propose developing an application capable of capturing news data in its entirety, minimizing the risk of missing important information. At the core of this solution is a web crawler- a sophisticated program designed to automatically browse the hyperlink structure of the web, systematically downloading linked pages to local storage. This crawling methodology is often the basis for web mining initiatives and search engine development. Since web information is distributed across billions of pages hosted on millions of servers worldwide, our application utilizes the PHP programming language to capture and process this data effectively. The main goal is to present pure news content to users without any irrelevant elements. We use a Data Flow Diagram (DFD) to model the system architecture and data flow. This approach provides a clear visualization of how web users can navigate through hyperlinks to efficiently access the desired news information. By implementing this system, we aim to improve the user experience of consuming news content, facilitate more effective data analysis, and contribute to the broader web information search and processing field.

Abstract

This study employs a sociometric analysis of Community Concern and Participation in Implementing the Lancang Kuning Nusantara Application for Forest and Land Fire Prevention in Toba Regency, Indonesia. With a sample of 401 respondents, the study aims to comprehensively understand social interactions and community engagement in this context. Results indicate that the perception score (X(i.1)) and participation score (X(i.2)) are high or significant, reflecting positive community awareness and active involvement in fire prevention activities. However, the acceptability score (X(i.3)) is low or insignificant, suggesting potential dissatisfaction or skepticism regarding the effectiveness or implementation of current programs. Furthermore, standard deviation analysis reveals that variability in respondent ratings is generally within control, with only 2 out of 15 testing points showing high standard deviation, while 13 are within acceptable limits. Nevertheless, the proportion of respondents who rate low (PRMR) exceeds the desired threshold of 10% across all variables, indicating that many respondents have low evaluations. These findings suggest a need for improved communication, education, and potential adjustments to enhance the acceptability and effectiveness of the fire prevention initiatives and the Lancang Kuning Nusantara System application.

Abstract

Teba, being an essential component of traditional Balinese dwellings, holds a significant role in community assignments, historical and societal contexts of Balinese culture, and ecological sustainability. Nevertheless, the process of urbanization and shifts in lifestyle have resulted in a decrease in Teba spaces and their conversion into less ecologically sustainable regions. This article explores initiatives to rejuvenate the design of Teba spaces in traditional Balinese houses to uphold a harmonious coexistence between environmental and cultural conservation in contemporary times. This research explores techniques and design solutions for Teba places that can effectively adapt to evolving circumstances while upholding traditional values. By doing so, it seeks to promote both environmental and cultural sustainability. This study employs a qualitative and ethnographic methodology to investigate ways for revitalization. These strategies involve the utilization of natural and local materials, the implementation of sustainable design techniques, and the creation of flexible and multifunctional spatial arrangements. The findings suggest that the restoration of Teba contributes to preserving biodiversity and enhancing air quality, reinforces cultural identity, and promotes sustainable tourism development. Integrating traditional techniques with modern technologies can optimize the functionality of Teba as both a productive green area and a center for cultural preservation. Hence, cooperation among architects, government entities, and the community is crucial in developing inventive and sustainable design solutions that enhance the cultural heritage of Bali within evolving circumstances.

Abstract

One of the contributors to Indonesia's economy is the fisheries sector, which has a high potential for development. Fisheries are a highly promising subsector for development in Indonesia's growth efforts. Based on data from the Central Bureau of Statistics of Dairi Regency, three types of aquacultures remain actively utilized in each subdistrict: ponds/freshwater ponds and paddy fields. This research aims to develop a fish production prediction system based on aquaculture types using the Multiple Linear Regression method. The accuracy of the prediction results will be measured using the Mean Absolute Percentage Error (MAPE). The results of this study indicate that in almost every subdistrict, especially pond aquaculture, the MAPE value is 20%, which means it has good accuracy. However, exceptions are found in the Siempat Nempu Hulu subdistrict, which has a MAPE value of 34.29%, and the Silahisabungan subdistrict, which has a MAPE value of 43.78%. Despite these values, they are still categorized as sufficient since they are 50%. The lower the MAPE value, the more accurate the prediction results. The findings of this research show that the multiple linear regression method can be considered correct. For future predictions, some results show negative values. For instance, in Silimapunggapungga subdistrict, a decline in production is predicted for 2024 with -114.779 tons and 2025 with -134.316 tons. The pessimistic prediction results are caused by the decrease in the X2 variable (area size), leading to a minor Y (production) value, potentially becoming negative if the contribution of X2 is no longer sufficient to balance the values of X1 (b1) and a. On the other hand, the Lae Parira subdistrict is predicted to experience an increase in production in 2024 by 87.024 tons and in 2025 by 84.380 tons. This system is implemented using the Python programming language. It is expected to help relevant stakeholders understand production trends and enhance the efficiency of fisheries resource management in the Dairi Regency.
