Abstract

Green lettuce (Lactuca sativa L.) is one of the leafy vegetables that is widely cultivated because it has a relatively short harvest time and high nutritional value, especially as a source of fiber, vitamin A, and vitamin K. This study aims to improve the growth of green lettuce using a DFT (Deep Flow Tecnique) hydroponic system equipped with IoT-based pH and TDS sensors. This study used a completely randomized design (CRD) with two treatments, namely P1 (50% AB Mix + 50% POC) using pH and TDS sensors and P2 (50% AB Mix + 50% POC) without pH and TDS sensors, each with two replications and nine samples per replication. The results showed that the use of pH and TDS sensors significantly increased plant height (32.44 cm), number of leaves (23.66 strands), leaf area (422.8 cm2), wet weight (236.4 g) and dry weight (23.41 g) compared to the manual method. Data analysis using an unpaired t-test at a 5% significance level showed significant differences in most growth parameters. IoT technology has proven effective in increasing the efficiency and productivity of hydroponic systems by providing real-time nutrients according to plant needs. This research supports the development of IoT technology for sustainable agriculture, while also having a positive impact on production efficiency and resource savings.

Abstract

Pakcoy (Brassica rapa L.) is a widely cultivated leafy vegetable with high economic value. Limited agricultural land and the need for more efficient cultivation systems encourage the use of hydroponic technology, particularly through the use of pH and TDS sensors to optimize nutrient management. This study aims to compare the growth of pakcoy plants using the Deep Flow Technique (DFT) hydroponic system with pH and TDS sensors and without sensors. The study used a Completely Randomized Design (CRD) with two treatments: 50% AB mix + 50% POC with sensors, and 50% AB mix + 50% POC without sensors, with nine replications. The parameters observed included plant height, number of leaves, leaf area, fresh weight, and dry weight. Data were analyzed using an unpaired t-test at a significance level of 5%. The results showed that the use of pH and TDS sensors significantly affected all growth parameters. The treatment with sensors resulted in higher average values, namely plant height of 25.1 cm, number of leaves of 17.3, leaf area of 514.6 cm², fresh weight of 236.28 g, and dry weight of 30.7 g compared to the treatment without sensors. Automatic nutrient monitoring creates stable solution conditions, thereby increasing nutrient absorption efficiency and plant biomass accumulation. This study concluded that the use of pH and TDS sensors is effective in optimizing and increasing the productivity of bok choy plants in hydroponic systems. It is recommended that IoT-based monitoring technology be applied more widely to improve cultivation efficiency, reduce costs, and support sustainable agriculture.

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

The Al Barkah Cooperative continues to produce goat milk, but the milk's distinctive aroma, unpopular with many, remains a limiting factor, resulting in low demand. To address this, innovation in goat milk processing is needed to ensure wider consumer acceptance. To enrich the cooperative's economic value, training and mentoring in dairy product processing are needed to optimize dairy farmers' milk production, including milk crackers and ginger milk. The training included lectures, demonstrations, and hands-on practice, covering everything from preparation to packaging. Evaluation results showed that 85% of participants felt they had gained new insights and were motivated to develop dairy products independently or in groups. Therefore, this activity has the potential to encourage business diversification, increase the added value of goat milk, and open wider market opportunities for the cooperative and the surrounding community.
