Abstract

This study aims to develop an Android-based calorie requirement application using the User-Centered Design (UCD) approach and to evaluate its usability through the System Usability Scale (SUS). The application calculates individualized calorie needs using the Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) formulas, while the Body Mass Index (BMI) feature functions only as a weight classification tool to support user awareness. Healthcare workers at Puskesmas Loa Ipuh were involved throughout the research, concept development, design, prototyping, and testing stages to ensure that the system aligns with real user needs. The UCD process used in this study consists of five stages: research, concept, design, development, and testing. The final application was built using the Kotlin in Android Studio and includes features such as calorie calculation, BMI calorie calculates, food recommendations, and daily nutritional tracking. Usability evaluation with the System Usability Scale involved 23 respondents and resulted in an average score of 82.60, which falls into the “excellent” category, indicating that the application is easy to use, efficient, and well accepted by target users. These findings demonstrate that integrating UCD with validated calorie estimation formulas can produce a functional and user-centered mobile application that supports users in understanding their daily calorie needs and improves accessibility to basic nutritional information.

Abstract

The rapid development of the e-commerce sector in Indonesia has made customer feedback a very important source of information in assessing the quality of goods and services. However, with so many reviews available, the manual assessment process often becomes complicated. The purpose of this study is to analyze customer sentiment towards PedagangAksesoris store on the Shopee platform using the Naïve Bayes Classifier method to identify positive and negative opinions that can help improve customer satisfaction. The data for this study was collected through web scraping of Shopee user reviews, followed by a preprocessing stage that included cleaning, filtering, removing affixes, and separating words. The data was then divided into training data and testing data to train and test the model. The Naïve Bayes method was applied by calculating word probabilities using Laplace smoothing, while model performance was evaluated using a Confusion Matrix through the RapidMiner application. The results of this study show that the Naïve Bayes model can classify customer reviews with a high degree of accuracy, with precision reaching 100% for the negative category and 80% for the positive category, as well as recall of 87.5% and 100%. These findings confirm that the Naïve Bayes method is an effective and efficient way to perform text-based sentiment analysis on reviews in e-commerce. The results of this sentiment analysis can be used as a basis for strategic decision-making by businesses to improve product quality, services, and customer satisfaction.

Abstract

The recent proliferation of electric vehicle (EV) charging stations has a serious impact on the power quality of the electricity distribution network. This issue cannot be ignored, as EV chargers are a type of non-linear load. With the increasing presence of non-linear loads in modern power systems due to the influence of EV charging, harmonic distortion, both THD and TDD, will become a significant problem, especially for distribution transformers that supply power to EVs. The increasing number of high-power electric vehicle batteries being charged at DC fast-charging stations, especially those with large load capacities, and when parallel with other vehicles, can cause overloads during peak hours, sudden power gaps, and voltage drops, all of which contribute to power quality issues, particularly in the surrounding electricity grid. Harmonic distortion, particularly due to the access of EV power supplies to the distribution network, which causes increased power quality disturbances, must be eliminated because the resulting odd harmonics will impact the performance of electrical equipment due to the suboptimal P and Q power in the distribution line. To understand the impact of charging electric vehicles, high-efficiency chargers are required in the power grid. Simulations revealed a high harmonic spectrum approaching 25%, but this was reduced to a much lower and safer level using passive filters.

Abstract

This study aims to analyze the implementation of educational human resource management (HRM) and its role in enhancing teachers’ professional competence in schools. In the current era of educational transformation, effective HRM is essential to ensure that teachers continuously develop their professional capacities in line with institutional goals and technological advancement. The research employed a descriptive qualitative approach, involving principals, teachers, and supervisors from five public schools in City Samarinda. Data were collected through in-depth interviews, field observations, and document analysis, and were analyzed using the Miles and Huberman interactive model, consisting of data reduction, data display, and conclusion drawing. The findings reveal that educational HRM contributes significantly to teacher professionalism through three primary dimensions: 1. systematic career planning and competency-based professional development, 2. continuous training, mentoring, and academic supervision, and 3. transparent and fair performance evaluation and reward systems. Supporting factors include visionary and participatory leadership, collaborative organizational culture, and policy support from educational authorities. However, budget constraints, insufficient training facilities, and low teacher motivation remain as barriers to optimal HRM implementation. The study concludes that strengthening integrated, adaptive, and data-driven HRM practices particularly those aligned with digital transformation is crucial to fostering teachers’ professional competence and enhancing educational quality. Educational HRM should not be viewed merely as an administrative function but as a strategic and transformational framework for building a professional, innovative, and sustainable learning environment in the twenty-first century.

Abstract

The rapid acceleration and advancement of information technology have significantly impacted the education sector, including higher education institutions. However, the implementation of existing systems has also introduced new challenges that are not yet addressed within the digitalization of information systems. One such issue is the absence of a dedicated platform for Student Online Complaint Services. This includes the lack of digital records as evidence and archives of complaints and issues raised by students, and the establishment of task forces such as the PPKS (Prevention and Handling of Sexual Violence). Despite these efforts, there is no digital-based platform to facilitate online complaints. The objective of this research is to develop a requirement model and user interface design to support the design of a web-based system that serves as a platform for students to easily report issues encountered during their studies. It also aims to assist campus stakeholders in capturing all student complaints as documentation for internal evaluation. The methodology used includes Agile Development Requirements Engineering with the Scrum model and the User-Centered Design (UCD) method to address the identified issues and research objectives. The research outcomes include the development stages of the website, system requirements, requirement model processes, requirement specification, and user interface design. furthermore, the research tested the user interface design on a website prototype, achieving a score of 87.5, classified as Excellent under the Adjective Rating system.

Abstract

Taxpayer compliance represents a fundamental aspect of a sustainable taxation system. This study investigates the influence of tax administration modernization, taxpayer knowledge, taxpayer awareness, and administrative sanctions on motor vehicle taxpayer compliance at the One-Stop Administration Services Office in Ciledug, Tangerang City. The research employed a quantitative explanatory design with multiple linear regression analysis. Primary data were collected through questionnaires distributed to 88 purposively selected respondents. The results reveal that modernization of the tax administration system, taxpayer knowledge, and administrative sanctions have no significant effect on compliance, while taxpayer awareness shows a positive and significant influence. These findings highlight that compliance is shaped more by intrinsic awareness and moral responsibility than by technical modernization or punitive measures. Thus, policy efforts should focus on strengthening taxpayer awareness and internal motivation as the foundation for improving voluntary compliance.

Abstract

Through South-South Cooperation, China develops opportunities for political and economic development in southern countries. This study wants to focus more on the influence of bilateral cooperation in the form of CPEC foreign aid by China in Pakistan, which influences Pakistan's domestic and foreign political policies related to the interests of the Chinese state. So the question of this study is how does CPEC aid affect the attitude of the Pakistani government that supports the Chinese government at the domestic level of Pakistan? In this research, the influence of Michel Foucault's theory of power will be explained. The use of deductive qualitative analysis, in which the researcher uses existing theories and then analyzes the data obtained with Michel Foucault's Power influence theory on China's foreign aid to Pakistan. The data collection technique through library studies is data collection by understanding and studying theories from various literature related to these cases. The results obtained from this study are the construction of Gwadar airport, which is more profitable for China. The Pakistani government tends to disregard the fate of the Uyghur ethnic group when UNHCR Pakistan does not extend the Uyghur refugee card, so that the Pakistani government deports the refugees. Then, the emergence of bride trafficking cases after easy access between China and Pakistan resulted in public protests and dissatisfaction with the ongoing CPEC cooperation, which was considered asymmetrical.

Abstract

This community service program supports the ProKlim (Program Kampung Iklim) initiative in RT 10 Petukangan Utara, South Jakarta by implementing a circular economy model through integrated tilapia (Oreochromis niloticus) and Pak coy (Brassica rapa var. chinensis) cultivation using aquaponic technology. Designed for densely populated urban areas with limited land, the aquaponic system converts fish waste into plant nutrients while plants purify the water, creating a closed-loop, zero-discharge process. The program consisted of awareness sessions, technical training, installation of aquaponic units, and community mentoring. Program outcomes indicate substantial improvements in environmental knowledge, climate adaptation awareness, and sustainable food-production skills. The system achieved 78–82% water savings, significantly reducing resource consumption compared to conventional methods. Pre- and post-training assessments showed a 90% increase in participants’ understanding of aquaponics and circular economy principles. Each production cycle generated 20 kg of Pak coy and 10 kg of tilapia, contributing to household nutrition and providing IDR 400,000–600,000 in additional microeconomic value through consumption and local sales. These quantitative results validate the effectiveness of aquaponic-based circular economy practices in supporting ProKlim objectives, particularly in enhancing climate adaptation, promoting sustainable resource use, and strengthening community empowerment in limited urban spaces.

Abstract

This study explores how students perceive the implementation of the Pancasila Student Profile Strengthening (P5) program under the theme of Local Wisdom, focusing on both the positive and negative aspects experienced in classroom and project activities. The research used a descriptive qualitative approach involving 30 students from class XI SAINTEK 3 at SMAN 5 Palangka Raya. Data were obtained through questionnaires and interviews to capture a broader and more personal view of their learning experiences. Findings show that 63% of students expressed positive perceptions toward P5, while 37% viewed it less favorably. Students who responded positively described P5 as enjoyable and meaningful, particularly because they could engage directly with cultural practices and teamwork activities that reflected Pancasila values. In contrast, others noted issues such as unclear instructions, lack of organization, and additional material costs, which made the experience less engaging. These differences highlight that while the P5 program supports cultural appreciation and character development, its success depends greatly on facilitation, communication, and resource support. The study suggests that better planning, teacher guidance, and collaboration with local communities are needed to enhance the relevance and sustainability of P5 activities. Overall, the results reflect that the theme of Local Wisdom remains a strong yet challenging approach to cultivating civic and cultural values in the Merdeka Curriculum.
