Abstract

This study is motivated by the ineffective internal control of inventory at PT Sejahtera Berkat Mandiri, which is attributed to the use of relatively basic technology and the suboptimal performance of internal auditors. This study aims to analyze the influence of information technology implementation and internal audit on the effectiveness of inventory internal control at PT Sejahtera Berkat Mandiri. The research is grounded in issues faced by the company, namely discrepancies between physical stock and system records, limited integration of information technology, and insufficient and non-comprehensive internal audit practices. A quantitative research method with a causal approach was employed. The study sample consisted of 75 respondents selected using total sampling technique. Data were collected through questionnaires and analyzed using multiple linear regression tests. The results show that the implementation of information technology significantly affects the effectiveness of inventory internal control, with a significance value of 0.000 and a regression coefficient of 0.827. Internal audit also has a significant influence on the effectiveness of inventory internal control, with a significance value of 0.000 and a regression coefficient of 0.461. Furthermore, the simultaneous implementation of information technology and internal audit significantly influences the effectiveness of inventory internal control, with a significance value of 0.000.

Abstract

Assessment systems across countries often face challenges in balancing the functions of selection and learning. Examinations often focus on measuring learning outcomes without considering the accompanying pedagogical and social impacts. This study aims to critically analyze and compare the assessment systems implemented by the Council for the Indian School Certificate Examinations (CISCE) in India and the National Education Examinations Authority (NEEA)/Gaokao. This study uses a qualitative, comparative document analysis design to provide an in-depth understanding of the characteristics, principles, and implications of both institutions' assessment systems. The research subjects consisted of 32 official documents. Data were collected through documentation studies and in-depth interviews. The instrument was a validity analysis sheet containing four main components: content relevance, indicator clarity, source consistency, and theoretical relevance. Data analysis was conducted descriptively and analytically using thematic categorization techniques based on four main dimensions: assessment instrument development, system validity and reliability, impact on learning, and institutional credential recognition. The results show that the CISCE excels in curriculum flexibility, integration of formative assessment, and recognition of international credentials. In contrast, the Gaokao excels in mass selection efficiency and national standard consistency. This study concludes that an effective assessment system must balance selection and student potential development to avoid excessive academic pressure. The implications of this research emphasize the importance of developing a national assessment system that is equitable, relevant, and oriented toward lifelong learning

Abstract

Stress has become a major global health concern affecting both physical and mental well-being. Conventional stress assessment methods rely on subjective self-reports that cannot capture real-time physiological changes. Existing systems are often limited to controlled laboratory environments or depend on traditional machine learning approaches requiring extensive manual feature engineering. This study aims to develop an Internet of Things–based stress monitoring system using deep learning to enable objective, continuous, and practical real-world stress detection.  The system incorporates wearable sensors using an ESP32-DevKit V1 microcontroller, a MAX30102 photoplethysmography sensor, and a Grove-GSR module for real-time acquisition of Heart Rate Variability and Galvanic Skin Response signals. A dual-branch Convolutional Neural Network architecture processes preprocessed HRV and GSR time-series data to automatically learn discriminative features without manual feature engineering. Data were collected from 30 participants, resulting in 8,100 labeled samples across four stress levels. The proposed CNN model achieved 91.3% classification accuracy, outperforming baseline machine learning models such as Support Vector Machine (78.4%), Random Forest (81.7%), and XGBoost (84.3%). Real-time system evaluation demonstrated an average latency of 1.47 seconds and battery endurance exceeding 13 hours, confirming the feasibility of continuous wearable stress monitoring. The integration of IoT infrastructure with deep learning provides an effective framework for physiological stress assessment, offering potential applications in preventive healthcare, workplace health management, and personalized mental-wellness monitoring.

Abstract

The development of a green economy in rural areas requires active community participation, particularly from women’s groups, supported by digital transformation and environmentally friendly technology. However, the Women’s Welfare Movement Group (PKK) of Lebak Village, Jepara Regency, faces several challenges, including reliance on conventional agricultural practices, low digital literacy, and the absence of online media for promoting local agricultural products. Therefore, this community service program aimed to empower PKK members through the application of aquaponic technology and the utilization of the Wonderful Taman Sari (WoTaS) digital application to enhance productivity and support sustainable economic practices. The program employed a participatory–educative approach implemented in five stages: socialization, aquaponic technology training, WoTaS application training, intensive mentoring, and evaluation. The results demonstrated a substantial improvement in participants’ knowledge and skills, with an average achievement rate of 91.9%. All participants (100%) were able to operate a simple aquaponic system, while 80% successfully used the WoTaS application independently to promote local products. In conclusion, this program effectively increased community productivity and digital literacy while strengthening the role of rural women in supporting a sustainable green economy.

Abstract

Since 2022, the application of the Internet of Things (IoT) in the healthcare sector has grown significantly, marked by the increasing adoption of wearable technology, artificial intelligence (AI), machine learning (ML), and blockchain integration. Research highlights India and China as leading contributors in this domain. IoT enables real-time monitoring of chronic diseases, tracking of patient vital signs, and detection of health protocol compliance. Integrated systems such as Monit4Healthy and RADAR-IoT support personalized medical recommendations and cross-platform interoperability. However, key challenges persist, including patient data privacy and security, system interoperability issues, data fragmentation, and barriers to user acceptance due to cost, digital literacy, and device comfort. Proposed solutions include blockchain for secure data sharing, adaptive congestion control for network performance, and user training to improve technology adoption. Therefore, successful IoT deployment in healthcare requires a comprehensive approach that addresses technological, social, ethical, and sustainability aspects to achieve an effective and inclusive transformation of health services.
