Abstract

High ambient temperatures inside tropical greenhouses can significantly raise nutrient solution temperatures in vertical hydroponic systems, disrupting nutrient uptake and reducing plant productivity. This study focuses on the design and development of a nutrient cooling system (chiller) using two TEC1-12706 thermoelectric modules (Peltier) arranged in series to enhance heat dissipation performance. The nutrient solution is pumped from the reservoir to the cooling chamber using a 12 V DC pump and recirculated in a closed-loop configuration. The chiller system is fully automated, controlled by two DH48S digital timers operating simultaneously: one activates Peltier 1, while the other controls Peltier 2 via the NC output (5 minutes) and the pump via the NO output (30 seconds), enabling alternating programmed cooling and circulation. The entire chiller unit is active only from 08:00 to 18:00 WITA using a KG316T programmable timer, corresponding to peak thermal stress hours inside the greenhouse. Results showed that despite greenhouse temperatures reaching up to 39.4 °C with relative humidity dropping to 47.6%, the chiller system maintained nutrient solution temperatures within the optimal 27–30 °C range. This design proved effective in reducing and stabilizing nutrient temperature under high heat microclimates. With its simple, automated, and energy-efficient architecture, the chiller system offers a promising solution for small-scale vertical hydroponics and greenhouse-based urban farming in tropical regions.

Abstract

Petroleum is currently the most commonly used fuel in Indonesia, but its availability is decreasing! Therefore, alternative energy sources are needed.  One solution is to convert agricultural and livestock waste into biogas, which is a renewable and environmentally friendly energy source! Biogas can be used for cooking, generating electricity, and even as fuel for vehicles! The aim of this research is to develop a mathematical model for predicting biogas volume! Can you believe it? The experiment involved creating biogas from a mixture of cow dung and water in a 1:2 ratio. The mixture was stirred until evenly distributed in a portable biogas floating drum. No gas was formed from the first day until the seventh day, but on the eighth day, gas began to form and its volume was recorded! A mathematical model approach, namely the Gompertz and Logistic Models, was used to predict the formation of biogas volume! And guess what? The results indicate that both models were able to predict the data accurately with a coefficient of determination (R2) of 0.99!  The validity test results show that the Gompertz model is the most reliable for making predictions! This is indicated by the bias value of 0.002, MSEP value of 0.000, and EI of 0.058. The validity test value is smaller than the validity test value obtained in the Logistic model, which is a bias value of 0.016, MSEP value of 0.005, and Ei value of 0.329.
