Abstract

Hydroponics wick system is a hydroponic system by utilizing the wick to absorb water and nutrients by utilizing capillarity power. This axis serves to connect the nutrient solution in the tub with planting medium. This study aims to : (1) determine the effect of the mix AB nutrient on plant growth in hydroponic lettuce; (2) determine the effect of Liquid Organic Fertilizer on plant growth in hydroponic lettuce; (3) the effect of substitution of hydroponic nutrient with a liquid organic fertilizer on plant growth in hydroponic lettuce. This study uses a completely randomized design with 5 treatments and repeated 4 times, resulting in 20 experimental units. The results showed : (1) administration of 5 ml/l A and 5 ml/l B gives the best results in growth of mustard plants; (2) provision of 3 ml/l A and 3 ml/l B + 100 ml/l POC also gave a good response to the growth of mustard plants; (3) administration of 2ml/l A and 2 ml/l B + 150 ml/l POC also gave a good response to the growth of mustard.

Abstract

Modern agriculture not only emphasizes increased production, but also environmental sustainability. One effort to support sustainable agriculture is the use of organic fertilizers, including the innovation of amino acid-based liquid organic fertilizers (POC) as an alternative or complement to chemical fertilizers. The research was conducted in the Babatan Hamlet area, Bakalan Village, Bugul Kidul District, Pasuruan City. The research used a non-factorial Randomized Block Design consisting of five treatments and five replications. The treatments were P0: 100% urea fertilizer (control); P1: amino acid concentration 5 ml l-1 + 75% urea; P2: amino acid concentration 10 ml l-1  + 75% urea; P3: amino acid concentration 15 ml l-1  + 75% urea; P4: amino acid concentration 20 ml l-1  + 75% urea. The parameters observed were plant height, number of leaves, leaf area, dry weight of upper plant, dry weight of lower plant, total dry weight of plant, leaf area index (ILD), net assimilation rate (NAR), relative growth rate (RGR), and plant weight-1. Based on the results of the study, it can be concluded that the concentration of amino acids 15 ml l⁻¹ + 75% urea proved to be more effective in increasing the yield and growth of bok choy with a weight of 126.23 g plant-1.

Abstract

The research consists of two stages, the first being the development of LOF production from water hyacinth and banana peel applied to ginger plants. The purpose of the study is to determine the extent to which the application of liquid organic fertilizer (LOF) can enhance the early growth of ginger plants. The second is the cultivation of ginger plants by applying various types of LOF compared to ginger plants without LOF application. The research was conducted from the end of August to November 2025 in Banjar Poh Village, Sidoarjo District, Sidoarjo Regency.  Research hypothesis: (1) It is suspected that different LOF applications will result in different early growth in ginger plants, (2) it is suspected that the use of banana peel LOF provides better early growth in ginger plants compared to other treatments. The study used a Randomized Block Design (RBD) method with one factor consisting of 4 treatments. The treatment involved the provision of types of LOF, namely P1 = without LOF; P2 = LOF water hyacinth; and P3 = LOF banana peel P4 = EM4 (Effective Microorganisms 4). Each treatment was repeated 3 times, and each repetition had 3 plant samples. Observations of the early growth of ginger plants include shoot height, number of shoots, and number of leaves. The obtained data were analyzed using analysis of variance, and if there were significant differences, it was followed by the Least Significant Difference (LSD) test at 5%.

Abstract

This study is meant to check out how giving different types of organic fertilizer, like Nutrizim granules, Nutrizim crumb, and liquid rabbit urine, affects the growth and yield of large chili peppers (Capsicum annuum L.). The research method used a Randomized Block Design (RBD) with five treatments and four replicates. The study was conducted from late May to early October 2024 in an open field at Pondok Pesantren Bhakti Bapak Emak, Jombang. The results showed that (a) the application of Nutrizim Granule and Crumb fertilizers significantly affected the growth of large chili plants (plant height, number of leaves, number of branches, and stem diameter). However, it did not significantly affect the yield of large chili plants (Total Fruits, Fruit Length, Fruit Diameter, Fruit Weight, Fruit Weight Per Plant, and Fruit Volume). (b) The application of Nutrizim Granular and Crumb Fertilizer combined with liquid rabbit urine organic fertilizer significantly affected the growth of large chili plants (Plant Height, Number Of Leaves, Number Of Branches, And Stem Diameter). However, it did not significantly affect the yield of large chili plants (Total Fruits Per Plant, Fruit Length, Fruit Diameter, Fruit Weight, Fruit Weight Per Plant, And Fruit Volume). Even though, large chili plants treated with the experimental treatments were able to produce a total of 8.46 fruits per plant, fruit length of 7.79 cm per fruit, fruit diameter of 1.05 cm per fruit, fruit weight of 6.00 g per fruit, fruit weight per plant of 47.39 g, and fruit volume of 6.55 ml per fruit.

Abstract

This study aimed to evaluate the effect of various types of synthetic organic fertilizers on the growth and yield of upland water spinach (Ipomoea reptans). The research was conducted in open field conditions using a Randomized Complete Block Design (RCBD) with three treatments: P1: control (urea); P2: Nutrizim granular organic fertilizer; P3: Nutrizim crumb organic fertilizer, each replicated three times. (a) The use of synthetic organic fertilizers had a significant effect on growth parameters, including number of leaves, plant height, and fresh weight of upland water spinach. (b) The plants treated with Nutrizim granular fertilizer produced a fresh weight yield of 36.15 tons/ha, which was not significantly different from the control treatment (47.61 tons/ha), with a yield difference of 11.46 tons between the Nutrizim granular fertilizer and the control. Thus, the use of Nutrizim granular organic fertilizer can support the growth and yield of upland water spinach.

Abstract

A significant problem is the lack of interest among Indonesian youth in pursuing careers in agriculture, which has profound implications for the nation's food security and economic stability. This research aims to identify agricultural development strategies that appeal to millennials and Generation Z to ensure food self-sufficiency, achieve a sustainable agricultural system, and reduce unemployment. Data sources for the research included academic journals, books, research reports, and articles published in scientific databases such as Google Scholar, Scopus, IEEE Xplore, and ScienceDirect. Inclusion and exclusion criteria were applied to ensure that only relevant and high-quality literature was included in the analysis. Agricultural development strategies to attract millennials or Generation Z include technology-based agricultural development, particularly digital technology, entrepreneurship-based agricultural development, sustainable agricultural systems, community-based and collaborative agriculture, and market-oriented agricultural product development. The implications of the research findings for education and policymakers are to avoid introducing millennials or Generation Z to conventional agriculture, which has been viewed negatively and unattractively, and to instead introduce them to a millennial-centered agriculture (oriented towards Generation Z's agricultural needs)
