Abstract

Hemoglobin is essential for diagnosing conditions like anemia and respiratory issues. Traditionally, the assessment of hemoglobin necessitates invasive techniques that involve blood draws, which can induce discomfort and present possible complications for patients. Recent advancements in non-invasive technologies have light-emitting diode (LED) to the development of smartphone applications and machine learning algorithms that allow real-time hemoglobin level estimation, eliminating the need for blood sampling. This not only improves patient comfort but also enhances access to ongoing health monitoring. This review aims to delve into the newest developments in smartphone-oriented strategies for hemoglobin estimation, highlighting their importance within contemporary healthcare practices and the potential implications they might have for more expansive clinical applications. Technological advancements have combined smartphones and artificial intelligence (AI) for non-invasive hemoglobin estimation, offering a promising alternative to traditional methods. These solutions optimize data collection and analysis processes, enhance diagnoses' accuracy, and facilitate timely medical interventions. Advancements in technology have revolutionized medical diagnostics, particularly in estimating hemoglobin levels non-invasively. AI methodologies have demonstrated significant results in accurately forecasting hemoglobin concentrations through a variety of analytical strategies. Future research should focus on the best configurations for these networks and the physiological concepts underpinning spectral data interpretations.

Abstract

The inefficient use of electrical energy and office facilities often leads to waste, equipment damage, and potential workplace hazards. This community service program focused on educating employees to use electricity and office facilities in a safe and efficient manner. The objectives were to raise awareness of safety and efficiency, reduce energy consumption and the risk of facility damage, and enhance professionalism in the use of office equipment. The program was implemented through an interactive online workshop via Zoom, consisting of a pre-test, delivery of materials and practical sessions on five key indicators (electrical devices, computers, air conditioners, lighting, and electrical panels), a post-test, and reflective discussions. The results demonstrated a significant improvement in participants’ understanding, as indicated by higher average post-test scores compared to pre-test results. Moreover, participants were able to identify risks of improper electricity use and apply energy-saving strategies. This activity successfully fostered a safer, more efficient, and professional work environment. In the future, further programs are needed to monitor work behavior, strengthen internal policies, and integrate energy-saving technologies to ensure the sustainability of these positive impacts.

Abstract

Due to the increasing trend in worldwide energy consumption, many new energy technology systems have emerged in the past decades. The implementation of energy storage system (ESS) technology in energy harvesting systems is significant to achieve flexibility and reliability in fulfilling the load demands. In this paper, several types of energy storage technologies available in the market are discussed to view their benefits and drawbacks. The main aim of this review is to provide a platform for readers especially those who seek to know more about ESS at a glance, to decide which ESS technology is best suited for any specific applications. This review would serve as a base for the initial state to make the right decision by referring to the criterias and characteristics of energy resources to get the optimal ESS technology. A comprehensive comparison among the various types of ESS technologies is outlined and elaborated to provide a better and clearer picture to the readers. Last but not least, the relevant recommendations and alternative choices for services related to the harvesting of solar PV energy are described too. It is hoped that the findings of this review article may be helpful to all readers interested in ESS technology.

Abstract

Energy resilience is a critical requirement in disaster-prone regions, where electrical infrastructure is highly vulnerable to natural hazards and prolonged power outages. Portable and modular solar power systems have emerged as promising solutions for enhancing resilience by enabling decentralized, rapidly deployable, and grid-independent energy supply. This paper presents a comprehensive review of the role of portable and modular photovoltaic-based power systems in improving energy resilience from a power electronics perspective. The review synthesizes recent literature on resilience concepts, system architectures, and converter-based control strategies relevant to emergency energy applications. Particular emphasis is placed on DC-first and hybrid AC/DC architectures, modular converter topologies, battery management systems, and energy management strategies that support reliable and fault-tolerant operation under variable and uncertain conditions. Practical deployment and performance considerations, including scalability, robustness, monitoring, and usability in disaster environments, are also discussed. The findings indicate that well-designed portable and modular solar power systems can significantly reduce recovery time, improve operational continuity, and decrease reliance on centralized grids and fuel-based generators. This review identifies key technical challenges and research opportunities to guide future development of resilient power electronic-based energy systems for disaster response and recovery.

Abstract

This community service program on electrical energy efficiency was implemented for IAES Indonesia employee partners, who faced a lack of understanding and skills in the safe, efficient, and economical use of electrical energy. The activity was conducted online with 56 participants and employed a pretest–posttest design to measure the training's impact. The instrument was a 25-item multiple-choice test covering five core competencies, with analysis using the Wilcoxon Signed-Rank Test. The results showed that 47 participants experienced an increase in their scores, with the mean rank of increase (27.46) being higher than the mean rank of decrease (17.50). The highest increase occurred in competency in electrical panels and KWH meters (17.14 points). Practically, this activity provides direct benefits for partners in the form of increased energy literacy, changes in behavior towards more efficient electricity use, and potential savings in electricity operational costs in the workplace. As a follow-up, this program recommends ongoing mentoring, monitoring of energy-saving behaviors, and the integration of energy-efficiency policies into partners' work environments to ensure the sustainability of the activity's impact.
