Abstract

Abstract. The increasing global population has spurred a greater need for agricultural products, particularly mushrooms, which are valued for their exceptional nutritional content and rapid growth rates. To optimize mushroom cultivation, it's vital to monitor environmental factors like temperature and humidity for ideal growth conditions. This study introduces an Internet of Things (IoT)-based mobile app for ongoing monitoring of temperature and humidity within mushroom cultivation structures, using sensor, microcontroller, LCD display, and mobile apps. The setup involves strategic placement of system components to efficiently gather data. The mobile app boasts a user-friendly interface for easy navigation and access to critical insights. The assessment of data transmission gives efficient information flow, less than 2% missclicks and 96% effectivity score, with minimal delays. Notably, the mobile app's features exhibit high accuracy and efficacy in delivering real-time updates on cultivation conditions. Furthermore, a survey using a Likert scale garnered positive user feedback, affirming the app's potential value in mushroom farming. This innovative system holds promise in elevating sustainability and profitability in the mushroom cultivation sector.  Keywords:  IoT, Monitoring system, Mushroom cultivation, Mobile application

Abstract

Windows are a critical factor in enhancing energy efficiency in buildings, especially in tropical climates, where they are exposed to high-intensity sunlight. The incorporation of transparent photovoltaics using various PV technologies offers the opportunity for windows to harness solar energy for building purposes. The energy-saving benefits of using transparent photovoltaics have been extensively analyzed in various countries, but there is still a lack of comparative studies focusing on tropical countries. Our study aims to fill this gap by assessing the potential of transparent photovoltaics in enhancing energy efficiency in buildings located in Jakarta, Singapore, Kuala Lumpur, Rio de Janeiro, and Kotoka. We developed an energy consumption model located in a tropical climate, utilizing the EnergyPlus software. The simulation results clearly indicate that integrating photovoltaics into the building is particularly advantageous due to consistent solar radiation and the need for cooling and ventilation, resulting in a substantial up to 59.3% reduction in total energy consumption. As a contribution, our research underscores the potential of transparent photovoltaics to revolutionize building energy efficiency in tropical climates, providing significant energy savings and promoting sustainable building practices. Addressing climate challenges, such as temperature and humidity management, necessitates the utilization of advanced materials and design strategies. Additionally, policy challenges encompass the requirement for favorable policies, incentives, and well-defined guidelines for the installation of PV windows.

Abstract

Energy plays a strategic role in human life today. In this case, energy is an interdisciplinary concept from the concepts of science and the environment to global social problems. One aspect of energy development is energy conservation, where efficient and rational use of energy is carried out without reducing energy use performance. To increase public awareness and participation on energy issues, especially those related to energy conservation, it is necessary to increase knowledge about energy in the wider community, one of which is through energy literacy. This is because knowing energy will empower people to make wise decisions and take responsible action regarding energy use. Energy literacy here can be obtained through formal and informal education. This study investigates the condition of energy literacy in Indonesian society in general through a sampling method, and it is found that the level of energy literacy in Indonesian society is on a moderate scale, but it is still not enough to reach the expected level of energy literacy, while the energy literacy level is less. Energy literacy and energy conservation will also be increasingly hampered. Therefore, it is hoped that an increase in education or energy literacy related to formal and non-formal education so that people are more familiar with and apply energy conservation in their daily lives.

Abstract

Energy and climate problems that occur encourage the intensification of energy use efficiency, one of which is in buildings. The building sector is the largest contributor to energy consumption when compared to other sectors due to the need for comfort in life, including to regulate air temperature, ventilation, and artificial lighting. Window innovation as a building component leads to adaptive smart windows technology that has energy saving features. The use of these windows is attractive because they are designed to adapt to changing environmental conditions to minimize large heat losses by adjusting their transmissivity and conductivity. Various types of smart windows have developed, one of which is electrochromic technology as dynamic glass technology which has been widely used as smart windows in commercial buildings. Several studies have shown that its use in buildings has been shown to save energy consumption in buildings through the HVAC and lighting aspects. However, in today's technology, its performance still requires external power to adjust their optical conditions. Therefore, the innovation in developing electrochromic smart windows technology that is integrated with photovoltaic technology is an interesting thing to do. The combination of the electrochromic solution with photovoltaic Si-TFSC placed on a glass substrate provides promising optical performance and energy benefits. The integration of electrochromic and photovoltaic devices provides better efficiency in energy saving, because photovoltaic and electrochromic devices can achieve electrochromic layer discoloration without an external power source. Given the photoelectric and optical modulation properties of electrochromic photovoltaic windows that can function as solar cell modules as well as powered smart windows on their own, this technology has a major advantage in applying sustainable energy to buildings. In its application in buildings, to improve device performance, the control system can be applied by adjusting environmental conditions according to the sensor system readings to obtain better device performance.
