ABSTRACT
One way to expand the time spent teaching science in elementary grades and teacher access to science resources is through partnerships with local universities. This article examines one collaboration that aimed to help students "Think Like a Scientist and an Engineer " using aquaponics. This self-sustainable garden combines aquaculture (fish farming) and hydroponics (growing plants in water). The Biological Sciences Curriculum Study (BSCS) 5E Instructional Model was used to introduce the aquaponics project. This article first discusses the University-School partnership, highlighting the project logistics, successes, challenges, and lessons learned, andfollows up with recommendations for future STEM teaching projects.
ABSTRACT
This study was conducted to assess the performance of vegetables using a non-greenhouse hydroponic system as a sustainable urban farming technology to increase food security (in terms of vegetable production and availability). Leafy lettuce (red and green) was grown using non-circulating hydroponics under a complete randomized design. The effect of hydroponics on growth and yield of the vegetables was studied. Six parameters were studied: plant height, length of the root, number of leaves, weight of lettuce, moisture content and dry matter. Data was collected 20 and 40 Days after transplanting and analyzed using T-test at 5% significance level with Origin Pro software (version 9.0). Soil-based cultivation was used as the control experiment. A significant difference (P < 0.05) existed at yield for lettuce grown under soil and hydroponics for;dry matter content (0.02, 0.01), fresh weight (0.03, 0.02) and root length (0.01, 0.02) in that order. Based on number of leaves which is the key edible part of the vegetable, hydroponics has the potential to perform as equally well as conventional farming. Further research can be done to study the nutritional composition of the lettuce and performance of the other vegetables using the system. © 2023

ABSTRACT
The COVID-19 pandemic has highlighted the need to adapt to and rebound from unexpected change and uncertainty. The increasing climate chaos of the Anthropocene additionally underscores the necessity of resilient societies and individuals. Individuals able to problem-solve in emergent situations are integral to a resilient society, and science education can develop these competencies both individually and collectively. We use the concept of resiliency to argue for science education that enables learners to adapt and respond in the face of disruption, unrest, and disaster. We focus specifically on the ways in which learning how to grow plants indoors can develop resilience on multiple levels while authentically facilitating science and engineering principles. This study seeks to explore how indoor agriculture might support science education for resiliency. We examine a higher-education project, the "Grow Pod," involving shipping container agriculture with first-year undergraduates. We argue that inclusion of indoor agriculture within science education has the potential to support both learning for and as resiliency. In our analysis, we note how the Grow Pod project supports a science education for resiliency through collective learning that helps learners understand plant basics and how to grow food, and a science education as resiliency which includes learning through and rebounding from challenges/mistakes, learning resourcefulness, and experiencing restorative benefits of working with plants.

ABSTRACT
The old conceptual dichotomy between the city and the countryside has often been a historical stumbling block for architects and urban planners. Whilst there have been many attempts to bring the city closer to the natural environment, some on grand scales, more modest experiments have often gleaned better results. Daniele Belleri is a partner at design and innovation office CRA-Carlo Ratti Associati, where he is in charge of all editorial and curatorial projects. He and the practice's founder, architect and engineer Carlo Ratti – who is director of the Senseable City Lab at the Massachusetts Institute of Technology (MIT) – together explore our contemporary options.

ABSTRACT
Work-induced stress is a large problem that has only been exacerbated by the coronavirus pandemic. Nature has beneficial effects on psychological and physiological well-being, with an abundance of scientific literature demonstrating the ability of greenery to reduce stress. As such, the fusion of nature-based design into the work and academic environments has the potential to greatly decrease student and employee stress. Primary methods of incorporating greenery indoors include living walls and potted plants. However, these methods fall short of creating an immersive environment that maximizes the positive impact on worker well-being, and additionally, barriers such as maintenance, costs, and extensive construction limit implementation. This paper outlines a new method to integrate nature into the work environment through 'EcoRealms,' which are immersive, natural spaces created by modular and self-maintaining 'living partitions.' These low-cost, easy-to-install partitions act as design elements to create a flexible space that serves worker well-being and enhances productivity. Discussed are prototypes that demonstrate the design's technical feasibility and results from a self-reported questionnaire that validate the positive impacts of the EcoRealm on wellbeing. © 2022 IEEE.
ABSTRACT
People always wanted to access natural things, like gardens, fresh forests, and agricultural fields which are associated with a range of health benefits. Studies have shown that exposure to natural and green space reduces stress, creates a happy mood, increases satisfaction in life and mental stimulation. The new normal created by the Covid 19 pandemic, has brought people to create gardens in their own place. The limiting things for people to adapt gardens in their own place: 1) Larger space is required to create a garden. 2) More water consumption 3) Consistent care for the plants 4) Doesn't have knowledge about the plants. Our project mainly focuses on these issues by providing an IOT based 'Movable mini hydroponic home garden with automated monitoring system' suitable for any geographic situation. We adopt the hydroponic concept, to create a movable garden, which can fit into any place like balconies, a small placecorner in the room. Also, it needs very minimal care and water consumption would also be minimal. Daylight and nighttime that the plant receives to determine the health of the plant. Therefore, we track the time the plant is exposed to sunlight and nighttime, which can be used to on the bulb (in case of indoor) or intimate the owner about the same. In the same way, the heat of the environment is also monitored and intimated to the owner, in the case of indoor, we either on the fan exhaust. The particular nutrition that the plant needs is been monitored by the sensor and intimated if it exceeds deficient. Insect bug could be detected by the sound it makes and the buzzer would be used to move it away from the plant. Daily messages would be given to the lower about the status of the plant, so they need not worry about the plant. © 2022 IEEE.
ABSTRACT
Agrivoltaic systems have the potential to maximize the usefulness of spaces in building rooftops. Urban farming systems improve the microclimatic conditions, which are beneficial to solar photovoltaic (PV) systems, as they lower the operating temperatures, resulting in a higher operating efficiency. Microclimate simulations by means of ENVI-met simulation showed that between 0800 h and 1800 h, PV temperatures in the plot that has crops below the PV system were on average lower by 2.83 °C and 0.71 °C as compared without crops on a typical sunny and cloudy day, respectively. Hence, we may see PV efficiency performance improvement of 1.13–1.42% and 0.28–0.35% on a sunny day and cloudy day, respectively. Data collected from a physical prototype of an agrivoltaic system suggested that evaporative cooling was responsible for the reduction in ambient temperatures. The presence of crops growing underneath the PV canopy resulted in the agrivoltaic prototype generating between 3.05 and 3.2% more energy over the day as compared to a control system with no crops underneath.
ABSTRACT
Along with the restrictions during the covid-19 pandemic, many new farmers are growing vegetables for their own needs or for sale and there are also many new farmers who are planting ornamental flowers which are currently booming, these new farmers are mothers or people who have free time at home. In growing vegetables using the hydroponic method, it does not require a large area of land and yields faster harvests by paying attention to the accuracy in providing nutrients, the intensity of light and temperature around the plant and the flow of water that is maintained to circulate oxygen and nutrients to the plant roots. In previous research, Hydroponic Plants powered by Solar Panels have been designed and tested but in the middle of the night the motor stops flowing water to the plants due to insufficient battery voltage, so it is necessary to find a solution so that the existing equipment can be optimized again, so this research aims to get a solution so that the existing system can be optimized by using the control system carried out by Arduino so that the pump can continue to flow water (oxygen and nutrients) for 24 hours continuously.
ABSTRACT
Resources such as fertile soil and clean water are already limited in many parts of the world. Additionally, the conventional use of arable land is becoming increasingly difficult, which is further exacerbated by climate change. Soilless cultivation systems do not only offer the opportunity to save water and cultivate without soil but also the chance to open up urban areas such as residential rooftops for food production in close proximity to consumers. In this review, applications of soilless farming systems are identified and compared to conventional agriculture. Furthermore, aspects of economic viability, sustainability and current developments are investigated. An insight into the most important soilless farming systems-hydroponics, aquaponics and vertical farming-is provided. The systems are then differentiated from each other and, as far as possible, evaluated in terms of their environmental impact and compared with conventional cultivation methods. Comparing published data analyzing the yield of hydroponic cultivation systems in comparison to soil-based cultivation methods enables a basic overview of the profitability of both methods and, thus, lays the foundation for future research and practical applications. The most important inert substrates for hydroponic applications are presented, and their degree of sustainability is compared in order to emphasize environmental impacts and affect substrate selections of future projects. Based on an assessment of the most important soilless cultivation systems, the challenges and developments of current techniques are highlighted and discussed.
ABSTRACT
With changes in the pattern of life or habits of the community caused by the outbreak of the Covid-19 virus in Indonesia, such as the prohibition of crowding and the recommendation to stay at home which makes people stay at home more often, gardening, especially hydroponic gardening, can is one of the activities that can be useful in filling spare time while at home, besides gardening it also has promising business potential. The so-called hydroponics is a method of farming using other planting media besides soil.In connection with the still outbreak of the Covid-19 virus in Indonesia, especially in the city of Bandung and its surroundings, this time community service activities are carried out virtually (online) through the Zoom application, in order to keep the event interactive and to avoid boredom from the participants, So in addition to the presentation of the material from the speakers, this time, community service activities also combine talkshow styles so that participants can be more interactive and better understand the material that has been delivered.PKM activities that have been implemented have reached the expected targets in terms of the number of participants, the material presented, and the achievement of the objectives of the activity. By participating in this PKM activity, participants can better understand the ins and outs of the hydroponic business, and indirectly increase motivation from within the activity participants to become a hydroponic business entrepreneur.
