Consumer liking of steamed green Chinese cabbage (Brassica rapa ssp. chinensis) cultivated in formulated vegetable waste-based organic hydroponic solutions

Chinese cabbage or pak choy (Brassica rapa ssp. chinensis) is often consumed because of its high nutritional content and several health advantages. Due to their promotion as being healthier and more ecologically friendly, hydroponic vegetables have seen a recent spike in consumer interest. The production of Chinese cabbage involved the processing of the vegetable waste to create various hydroponic solution formulations (F1 = banana peels, eggshells, and bean sprouts; F2 = banana humps, onion peels, bean sprouts, and moringa leaves; F3 = moringa leaves, onion peels, and bean sprouts; and F4 = AB Mix solution). They were applied at concentrations of 600, 900, 1,200, and 1,500 parts per million. The aim of this study was to investigate the relationship between the type of hydroponic growth solutions and Chinese cabbage customer acceptance. As a result, using a hedonic test of consumer liking, a panel of 32 untrained individuals was asked to show their liking score on sensory attributes of Chinese cabbage. There was a significant difference in the color liking of Chinese cabbage as an effect of hydroponic solution formulation. However, both organic vegetable waste-based formulations did not statistically substantially affect consumer acceptance, which includes color, taste, flavor, texture, and overall liking. Ultimately, vegetable waste-based organic formulations can be used to produce Chinese cabbage that is as acceptable to customers as those prepared with inorganic AB-Mix solution.

Growth response of mustard greens (Brassica juncea L.) to nutrient formulations in hydroponic media

Abstract The production of mustard greens (Brassica juncea L.) by applying a hydroponic technique has been widely operated in urban areas. One of limited factor on hydroponic operation is a high spending cost on nutrition input i.e. AB Mix nutrition. The aim of this research was to evaluate the effectiveness of NPK for substituting AB Mix on hydroponic operation of mustard greens. The research was conducted at BPTP Jakarta, from February to April 2021. Five combinations of NPK substitution on AB Mix were evaluated, namely: 100% AB Mix as control (H0), 75% AB Mix - 25% NPK (H1), 50% AB Mix - 50% NPK (H2), 25% AB Mix - 75% NPK (H3), 100% NPK (H4). All the treatments were arranged on a completely randomized design with 4 replications. The results showed that combination of AB Mix 25% + NPK 75% (H3) yield mustard greens growth similarly with the control plant (100% AB Mix). This finding approved that proportion of NPK for AB Mix substitution was appropriate up to 75% on hydroponic operation for mustard greens cultivation.

Analysis of Kale Vegetable Production (Brassica oleracea var. sabellica) in Catfish Pond Water Media Using Floating Net Aquaponics Technology

Kale (Brassica oleracea var. sabellica) is a horticultural plant that looks like broccoli and cabbage, but its leaves are headless. This study aims to analyze the production of kale (Brassica oleracea var. sabellica) vegetables in catfish pond water media using floating net aquaponics technology, focusing on the impact of various doses of organic fertilizer on plant growth. The method used was the analysis of variance, and if a significant difference were found, Duncan's Multiple Range Test at the 5% level would be applied further. The results showed that various doses of organic fertilizer did not produce significant differences in plant height, although higher doses tended to increase. However, applying organic fertilizer significantly increased the number of kale plant leaves, with a dose of 100 ml/L producing the highest number of leaves compared to the control. This indicates that organic fertilizer effectively supports kale plants' vegetative growth. On the other hand, the treatment using AB Mix and catfish ponds as media did not show significant differences in the fresh weight of kale plants at various observation periods. Variations in plant wet weight were not statistically different enough to affect the study's conclusions. These findings indicate that although organic fertilizer significantly increased the number of leaves, aquaponic media with AB Mix and catfish ponds did not significantly affect plant wet weight.

Susut Bobot dan Kadar Air Tajuk Tanaman Pakcoy Akibat Pengaruh Jenis Media Tanam dan Konsentrasi Nutrisi AB Mix

Pakcoy (Brassica rapa subsp. chinensis) is a type of vegetable commonly cultivated using hydroponic systems. The weight loss and moisture content of pakcoy plant shoots can be influenced by the type of growing media and the concentration of AB Mix nutrients. Each type of growing medium has distinct physical and chemical properties. The combination of different AB Mix nutrient concentrations with various growing media types results in varying weight loss and moisture content in the plant shoots. Pakcoy plants with lower weight loss and higher shoot moisture content exhibit better storage resistance. The research method employed was a Factorial Randomized Block Design with two factors: the first factor being the type of growing media (burnt rice husk, cocopeat, rockwool), and the second factor being the concentration of AB Mix nutrients (1,000, 1,200, and 1,400 ppm). The results indicated that rockwool, combined with an AB Mix nutrient concentration of 1,000 ppm, resulted in the lowest weight loss and the highest shoot moisture content compared to other treatments.
