A smart irrigation system based on soil moisture sensors supported by photovoltaic energy is an innovation to address water use efficiency in the agricultural sector, especially in remote areas. This technology utilizes photovoltaic panels as a renewable energy source to operate water pumps, while soil moisture sensors provide real-time data that is used to automatically manage irrigation according to plant needs. This technology not only increases the efficiency of water and energy use but also supports environmental conservation by reducing dependence on fossil fuels. This research was conducted using a Systematic Literature Review (SLR) approach guided by the PRISMA framework to analyze trends, benefits, and challenges in implementing this technology. The analysis results show that this system offers various advantages, including energy efficiency, reduced carbon emissions, and ease of management through the integration of Internet of Things (IoT) technology. Several challenges remain, such as high initial investment costs, limited network access, and obstacles. Technical matters related to installation and maintenance. Various solutions have been proposed, including providing subsidies for small farmers, implementing radiofrequency modules, and using modular designs to simplify implementation. This study contributes to the development of a conceptual framework that can be adapted to various geographic and socio-economic conditions. Potential further developments include the integration of artificial intelligence and additional sensors to increase efficiency and support the sustainability of the agricultural sector globally.

Building-Integrated Photovoltaics (BIPV) is a transformative approach to sustainable energy, which integrates photovoltaic systems as integral elements of building structures, such as facades, roofs, and windows. This bibliometric review aims to comprehensively analyze the evolution, trends, and challenges in BIPV research by referencing more than 10,000 publications indexed in Scopus. Key findings highlight the growing importance of cross-disciplinary collaboration in engineering, architecture, and environmental science to improve BIPV efficiency, aesthetic integration, and economic viability. Despite substantial progress, challenges remain, including high initial costs, regulatory limitations, and the need for innovative materials and energy storage solutions. Emerging trends underscore the potential of BIPV in urban planning and sustainability initiatives, supported by increased collaboration and international adoption in regions with supportive policies. This review identifies research gaps in cost-effective production, adaptive materials, and integrated energy management solutions, which offer future pathways for BIPV innovation. This review serves as a reference for academics, practitioners, and policymakers aiming to advance the adoption of BIPV, contributing to global efforts towards energy sustainability and low-carbon urban development.

The production of hydrogen through water electrolysis has emerged as a promising alternative to decarbonizing the energy sector, especially when integrated with renewable energy sources. Among the key operational parameters that affect electrolysis performance, temperature and current density play a critical role in determining the energy efficiency, hydrogen yield and durability of the system. The study presents a Systematic Literature Review (SLR) that includes peer-reviewed publications from 2018 to 2025, focusing on the effects of temperature and current density across a variety of electrolysis technologies, including alkaline (AEL), proton exchange membrane (PEMEL), and solid oxide electrolysis cells (SOEC). A total of seven high-quality studies were selected following the PRISMA 2020 framework. The results show that high temperatures improve electrochemical kinetics and reduce excess potential, especially in PEM and SOEC systems, but can also accelerate component degradation. Higher current densities increase hydrogen production rates but lead to lower Faradaic efficiency and increased material stress. The optimal operating range was identified for each type of electrolysis, with PEMEL performing best at 60–80 °C and 500–1000 mA/cm², and SOEC at >750 °C. In addition, system-level studies emphasize the importance of integrating hydrogen production with flexible generation and storage infrastructure. The review highlights several research gaps, including the need for dynamic modeling, multi-parameter control strategies, and techno-economic assessments. These findings provide a basic understanding for optimizing hydrogen electrolysis systems in low-carbon energy architectures.

The utilization of renewable energy, particularly solar panels, has rapidly developed as a solution to reduce dependence on fossil fuels and carbon emissions. This study examines the application of solar panels across various sectors, including transportation, residential, commercial, industrial, and agricultural, using a systematic literature review (SLR) approach. The results indicate that solar panels provide significant benefits in supporting energy sustainability, such as high efficiency in electric vehicles, carbon emission reduction in the transportation sector, and energy cost savings in commercial buildings. In the agricultural sector, solar panels are used for irrigation and crop storage. Additionally, technological advancements such as bifacial panels and integration with energy storage systems enhance efficiency and application flexibility. However, challenges such as high initial costs, location limitations, and technological efficiency remain major barriers. Through an analysis of the advantages and disadvantages of three types of solar panels (monocrystalline, polycrystalline, and thin-film), this study provides strategic guidance for selecting the most suitable technology for specific needs. The study concludes that the adoption of solar panels can be accelerated through technological innovation, cost reduction, and government policy support. With optimal utilization, solar panels have significant potential to drive the transition toward sustainable energy in the future.

This study presents a simulation-based model of micro-scale energy harvesting using Droplet-based Electricity Generator (DEG) technology, which aims to address the energy challenges faced by remote communities. Utilizing five-year (2019-2023) rainfall data from the Ciaul weather station in Sukabumi, Indonesia, we estimated the energy yield of the DEG system based on the known electrostatic output per water droplet (3.2 μJ per 100 μL). The model evaluates the monthly and annual energy availability per square meter and compares the results with the energy requirements of basic electrical loads such as LED lights. The results show that even a small DEG array (1-10 m²) has the potential to support intermittent micro-loads in areas with high rainfall. This simulation framework supports future prototyping and hybrid integration of DEG systems in rural renewable energy planning.
