Abstract

Spinach is a vegetable that people like since it owns high nutrition. The high demand for green spinach is not balanced with the amount of production due to the narrowing of agricultural land. Hydroponic spinach cultivation is one of the efforts to solve the problem. Deep Flow Technique (DFT) is a commonly used hydroponic system. The study aimed to examine the characteristics of energy, water, and nutrient consumption on green spinach cultivation as well as the performance of theDFT fertigation system. The study used the analytical descriptive method. The result showed that the energy consumption used was 51.86 during one planting time or the costs incurred for the use of electricity was Rp76.104,64. In addition, water and nutrient consumption used during the planting period was 103.63 liters and 1.504 liters. System performance was viewed in terms of good uniformity with 93% as an average of plant height, 81.75% as the net plant weight, and 80.05% of root length with a faster harvesting time when compared to conventional cultivation namely 22 days. Water use efficiency resulting from the study was 112.127 kg/m3 and 2.82 kg/m2 of land productivity.

Abstract

Monitoring microclimate conditions, including temperature, humidity, and light intensity, is crucial for maintaining plant health and productivity in vertical indoor hydroponic systems. These conditions directly influence essential physiological processes such as photosynthesis and respiration, affecting growth and yield quality. Manual monitoring methods often suffer from inefficiencies such as slow data collection, operator dependency, and human error. This can delay responses to sudden microclimate changes, leading to plant stress and reduced productivity. This study aims to design a real-time microclimate monitoring and graphical interface system for indoor vertical hydroponics using a User-Centered Design (UCD) approach. The system integrates DHT11 and BH1750 sensors to measure temperature, humidity, and light intensity, respectively, with data processing performed using a Raspberry Pi 3 Model B+. The system performance was evaluated over 24 h using the root mean square error (RMSE) and accuracy metrics. Based on this analysis, the RMSE values for temperature, humidity, and light intensity were 2.398, 1.483, and 392.225, respectively, with an overall accuracy of 97.33%, demonstrating high reliability. Two interface prototypes, Design A and Design B, were developed using distinct visual approaches and evaluated by ten respondents across six criteria: appearance, color, layout, information, icon, and font. Design A outperformed Design B, achieving a higher average score (49 versus 43.4), reflecting its superior clarity and intuitive design. These findings highlight the potential of the proposed system to enhance microclimate management and optimize plant growth in indoor vertical hydroponics.
