Cultivation of Water Spinach Using A Hydroponic Systems at Different AB Mix Concentrations

Abstract

Water spinach is one of the most popular vegetable commodities in Indonesia. Currently, limited land due to plastic waste and uncertain climate change are inhibiting factors for plant cultivators. Efforts that can be done is to carry out cultivation activities to water spinach hydroponically. Hydroponic cultivation can use the wick system because it is easy to apply and does not require expensive costs. To support optimal growth of water spinach and reduce plastic waste in Indonesia, presenting AB Mix nutrition and the use of plastic bottles as a nutrient container in hydroponic cultivation are efforts to obtain quality water spinach production. This study aims to determine the response of water spinach plants to the use of hydroponic growing systems, as well as to obtain information regarding the best concentration of AB Mix. The experimental method used was a completely randomized design, which consisted of 3 levels, namely the nutrient concentration of 800 ppm, 1000 ppm and 1200 ppm. The results of the various concentrations of mixed AB showed significantly different effects on the parameters of plant height, number of leaves and weight of fresh plants. AB Mix concentration treatment of 1200 ppm was the best treatment for all observed parameters.

Smart Aquaponics: An Automated Water Quality Management System for Sustainable Urban Agriculture

“…Through real-time monitoring and alerts, coupled with Wi-Fi-enabled control via the ESP822 module, the system promises enhanced management capabilities, ensuring the health and productivity of the aquaponic setup. Research for managing water quality in treatment plants has intensified due to its substantial potential to enhance operational efficiency, ensure regulatory compliance, and improve overall water treatment effectiveness [16][17][18]. Simultaneously, research efforts [19][20][21][22][23][24][25][26][27][28][29][30] have concentrated on refining water management control.…”

Response Water Spinach (Ipomoea Aquatica) to Different Medium Treatment with AB Mix Nutrients on The Cultivation Hydroponic DFT (Deep Flow Technique)

“…One of the most widely used plant cultivation methods, especially horticultural crops, is the hydroponic method. Water spinach is a plant that is easy to cultivate and can be done in the midst of limited land using the hydroponic method (Nanda and Khozin, 2022). According to mulasari (2018) hydroponic is a business of cultivating plants without using soil media but using nutrient mineral solutions or using other media such as coconut fiber, broken brick, sawdust and others.…”
