Abstract

Red lettuce (Lactuca sativa var. crispa) cultivated using hydroponic systems requires precise nutrient management to optimize growth. Internet of Things (IoT)-based sensors, particularly pH and Total Dissolved Solids (TDS) sensors, enable real-time automatic regulation of nutrient solutions. This study aimed to evaluate the effect of IoT-based nutrient automation using pH and TDS sensors combined with a 50% AB Mix and 50% nano gamal leaf POC formulation on the growth of red lettuce. Data were analyzed using an independent t-test at the 5% significance level. The results showed that all growth parameters in the sensor-based system were significantly higher than those in the manual system (p < 0.05). The automated system improved nutrient balance, increased nutrient absorption efficiency, and maintained stable pH and TDS values throughout the growth period. This study demonstrates that IoT-based nutrient automation effectively enhances hydroponic red lettuce productivity and supports sustainable agricultural practices through efficient resource management. Statistical analysis confirmed significant differences between treatments, indicating that IoT technology improves the efficiency and productivity of hydroponic systems by providing real-time nutrient supply. This research strengthens the potential application of IoT technology in sustainable agriculture and contributes to improved production efficiency and resource savings.

Abstract

Enhancing rice productivity is essential to meet increasing national food demands, especially for local varieties such as Bujang Marantau from Tanah Datar District. This variety is highly valued for its yield potential and pest resistance; however, it faces challenges related to declining seed quality. This research investigates the effect of incorporating an ecoenzyme into a Trichoderma asperellum formulation, using a red glutinous rice medium, on the germination and early growth of Bujang Marantau rice. The study employed a Completely Randomized Design (CRD) with eight ecoenzyme concentrations (0%, 10%, 20%, 30%, 40%, 50%, 60%, and 70%) and four replications. The measured parameters were the fresh and dry weights of seedlings at seven days after germination. Data were analyzed using ANOVA at a 5% significance level, followed by DNMRT when significant differences were detected. The results indicated that ecoenzyme application significantly affected seedling fresh weight during germination but did not influence dry weight. A 30% ecoenzyme concentration was found to be the most effective in promoting germination biomass. This finding demonstrates that ecoenzyme incorporation at this optimal concentration enhances Bujang Marantau rice seedling vigor and represents a promising approach for improving seed quality. Further research is recommended to evaluate field performance and the long-term effects on productivity.
