Abstract

Water quality is defined as the condition of water assessed and evaluated based on specific parameters and standardized measurement methods. Degraded water quality—such as increased turbidity—can result in reduced dissolved oxygen levels, decreased feeding activity in fish, and obstruction of fish gills by suspended sediment particles. Consequently, water quality serves as a critical factor in aquaculture monitoring, as it directly influences fish growth performance and overall pond productivity. This study aims to develop an integrated water-quality monitoring system for tilapia aquaculture ponds, utilizing a turbidity sensor to detect water clarity and an ultrasonic distance sensor (SRF-05) to measure water level. Both sensors interface with a control unit based on the ATMega328p microcontroller implemented on an Arduino Uno board. The control unit processes sensor data and regulates water conditions through a single relay module connected to two 10W water pumps. The acquired sensor data are transmitted and visualized in real time on an Android application, developed using the Java programming language, to facilitate remote monitoring. The system is expected to support tilapia farmers by providing continuous, accessible, and automated water-quality surveillance, thereby enhancing management efficiency and improving aquaculture outcomes.

Abstract

This study aims to develop and evaluate an integrated framework combining COBIT 2019 and ISO/IEC 27001 to enhance IT governance and information security management. Using a qualitative-descriptive approach, the research involved document analysis, expert interviews, and a case-based validation within a government institution. The integration process consisted of three phases: mapping, harmonization, and synthesis, which resulted in the development of the Integrated IT Governance and Security Framework (IGSF). The findings reveal a high degree of alignment between COBIT 2019’s governance domains and ISO/IEC 27001’s security control structures, forming a unified model that strengthens strategic alignment, risk management, and compliance. Expert validation confirmed that the IGSF facilitates better communication between governance and security teams, reduces redundancy, and enhances operational efficiency. The practical case study demonstrated improved coordination, documentation, and audit readiness following implementation. This study contributes to IT governance and information security literature by presenting a structured, adaptable framework that organizations can adopt to achieve both governance excellence and security resilience. The results also suggest potential for future quantitative evaluation to measure the impact of this integration on organizational performance and compliance outcomes.

Abstract

Dermatoscopy image-based skin lesion classification is a challenge in dermatology due to the high visual variation between lesion types and the imbalanced class distribution in the dataset. In this study, a Hybrid Vision Transformer–ConvNeXt architecture is proposed, combining the global attention capability of Vision Transformer (ViT) and the spatial feature representation of ConvNeXt, to improve the classification performance of skin lesion images on the HAM10000 dataset. This study also applies Multi-Task Focal Loss, auxiliary classifier, and Weighted Random Sampler to effectively address the class imbalance. In addition, the Medical Test-Time Augmentation (TTA) approach is used in the inference stage to improve the stability of predictions. The model is trained using a two-stage strategy (head training and full fine-tuning), as well as optimization based on AdamW and Cosine Annealing Warm Restarts. The test results show that the proposed model successfully achieves a validation F1-Score of 0.8723, and after TTA it increases to 0.90, surpassing the baseline of ViT and single ConvNeXt. These findings indicate that the integration of ViT–ConvNeXt with loss strategy and medical TTA is able to significantly improve the performance of skin lesion classification, and has the potential to be applied as a clinical diagnosis support system.

Abstract

This study aims to analyze the effect of capital structure, operational efficiency, liquidity ratio, and firm size on the profitability of national private banks in Indonesia, with Good Corporate Governance (GCG) as a moderating variable. This research employs a quantitative approach using secondary data derived from annual financial statements and GCG implementation reports of national private banks listed on the Indonesia Stock Exchange during the 2018-2023 period. The research sample consists of 11 national private banks with a total of 66 observations. Profitability is measured using Return on Assets (ROA), capital structure is measured by the Debt to Equity Ratio (DER), operational efficiency by the Operating Expense to Operating Income ratio (BOPO), liquidity ratio by the Loan to Deposit Ratio (LDR), and firm size by the natural logarithm of total assets. Data analysis was conducted using panel data regression with moderation testing. The results indicate that capital structure and operational efficiency have a significant effect on bank profitability, while the liquidity ratio and firm size do not have a significant effect. Furthermore, Good Corporate Governance is unable to moderate the effect of capital structure and operational efficiency on profitability, but is able to moderate the effect of the liquidity ratio and firm size on bank profitability. These findings suggest that the role of GCG in enhancing bank profitability is contextual and depends on the characteristics of the moderated variables.

Abstract

Lecturers in higher education face challenges in balancing professional and personal responsibilities, necessitating flexible work policies and supportive leadership to enhance well-being. This study aims to examine the influence of Flexible Working Arrangement and Supervisor Trustworthiness on Work-Life Balance, with Perceived Organizational Support as a mediator, among tenured lecturers at Universitas Prima Indonesia. A quantitative approach was employed, utilizing a structured questionnaire with a 5-point Likert scale to collect data from 129 tenured lecturers, representing a 92% response rate from the total population of 140. Data were analyzed using Partial Least Squares Structural Equation Modeling to test direct and mediated relationships. The findings reveal that Flexible Working Arrangement and Supervisor Trustworthiness significantly enhance Perceived Organizational Support, which in turn positively affects Work-Life Balance. Additionally, Perceived Organizational Support mediates the relationship between both Flexible Working Arrangement and Supervisor Trustworthiness and Work-Life Balance. These results highlight the critical role of flexible policies and trustworthy leadership in fostering lecturers’ well-being in the Indonesian academic context, where such studies are limited. The study suggests that universities implement flexible schedules and leadership training to promote Work-Life Balance, contributing to improved job satisfaction and institutional productivity.

Abstract

Most of Gedebage area consist of expansive soil and always greatly induce disturbance to structure of foundation. Nature properties of expansive soil is a high plasticity value, low soil shear strength, high swelling, and large potential for shrinkage. One solution for soil improvement is to use an additional material to stabilize this soil. Additional material uses locked emulsion asphalt 8% and mud from Lapindo area in variation of 3%, 6%, 9% and 12%. The results of testing the physical and mechanical properties after stabilization indicates increasing of density value around 68%. Plasticity index tends to decrease until 10% from CBR test. CBR values with curing time of 14 days are 8.1% for unsoaked and by 4.6% for soaked conditions.
