AbstrakKale merupakan tanaman hortikultura yang kaya antioksidan, karotenoid, dan antosianin. Kale dapat dibudidayakan secara hidroponik dengan menggunakan AB mix sebagai pupuk, namun nutrisinya sering mengendap di dasar bak sulit terserap oleh akar. Penambahan Pupuk Organik Cair (POC) yang disemprotkan ke daun diharapkan dapat menjadi nutrisi tambahan bagi tanaman. Penelitian ini bertujuan untuk menganalisis respon pertumbuhan dan produksi tanaman kale terhadap penambahan POC pada sistem hidroponik Deep Flow Technique (DFT). Penelitian menggunakan Rancangan Acak Kelompok dengan 5 perlakuan, yaitu dosis POC (0; 10; 20; 30; dan 40 mL/L). POC disemprotkan ke daun setiap minggu sejak hari ke-0 sampai 35 hari setelah tanaman. Analisis data menggunakan sidik ragam (ANOVA) dan uji lanjut DMRT pada taraf 5%. Penambahan POC berpengaruh nyata pada pertumbuhan tanaman kale (P <0,05), yaitu POC konsentrasi 10 mL/L dapat meningkatkan panjang akar tanaman (41,25 cm) dan berpengaruh tidak nyata terhadap parameter lainnya seperti tinggi tanaman, jumlah daun, diameter batang, berat basah, dan kering tanaman serta berat layak konsumsi. Namun, tanaman kale yang disemprot POC memiliki nilai rata-rata semua parameter lebih tinggi dari kontrol (0 mL/L). Perlakuan POC 10 mL/L memiliki rata-rata parameter pertumbuhan dan produksi lebih tinggi dari yang lainnya, sehingga berpotensi meningkatkan pertumbuhan dan produksi tanaman kale pada sistem hidroponik DFT.AbstractKale is a horticultural plant that is rich in antioxidants, carotenoids and anthocyanins. Kale can be cultivated hydroponically using AB mix as fertilizer, but the nutrients often settle at the bottom of the tub and are difficult for the roots to absorb. The addition of Liquid Organic Fertilizer (POC) which is sprayed through the leaves is expected to provide additional nutrition for plants. This research aims to analyze the growth and production response of kale plants to the addition of POC in the Deep Flow Technique (DFT) hydroponic system. The study used a randomized block design with 5 treatments, namely POC doses (0; 10; 20; 30; and 40 mL/L). POC is sprayed on the leaves every week from day 0 to 35 days after planting. Data analysis used analysis of variance (ANOVA) and further DMRT test at the 5% level. The addition of POC has a significant effect on the growth of kale plants (P <0.05), namely POC concentration of 10 mL/L can increase plant root length (41.25 cm) and has no significant effect on other parameters such as plant height, number of leaves, stem diameter. , wet and dry weight of the plant and weight suitable for consumption. However, kale plants sprayed with POC had an average value of all parameters higher than the control (0 mL/L). The 10 mL/L POC treatment has higher average growth and production parameters than the others, so it has the potential to increase the growth and production of kale plants in the DFT hydroponic system.

Fertilization is important in increasing crop production. The use of liquid organic fertilizer (LOF) in addition to inorganic fertilizer in crop cultivation is expected to reduce the use of inorganic fertilizer and increase growth and production. The research aimed to determine the effect of LOF on peanut growth and production and to obtain the right dose to reduce the use of inorganic fertilizer doses. The research used a factorial Randomized Group Design (RGD) with two factors. The first factor was LOF dose (0, 3, 5, and 7 ml/L/Plot) and the second factor was inorganic fertilizer dose (0, 25, 50, and 100% of the recommended dose). Data analysis using ANOVA and DMRT. The results showed that the dose of LOF had a very significant effect (P0.01) on plant height, number of leaves, leaf area, number of filled pods, and total number of pods. The best dose in improving all these parameters was LOF 3 ml/L/Plot. The combination treatment of LOF and inorganic fertilizer had a very significant effect (P0.01) on the number of filled pods, but not significant effect (P0.05) on other parameters. The best combination of LOF dose and inorganic fertilizer was C1A1 (3 ml/L/Plot LOF + 25% Inorganic) which produced almost the same number of filled pods as C0A2 (0 ml/L/Plot LOF + 50% Inorganic), and higher than other treatments. The C1A3 treatment also produced higher fresh pod weight and dry pod weight than the other treatments. The application of LOF 3 ml/L/Plot + 25% inorganic fertilizer from the recommended dose can increase peanut production, and can reduce the use of inorganic fertilizer by 75%.

Cardamom (Amomum compactum) is an aromatic spice plant with numerous benefits, widely used in cooking, medicine, and beverages. The high demand for cardamom remains unmet due to the lengthy germination period required for cardamom seeds and the inability of cardamom shoots to thrive when planted independently from the mother plant. The presence of the mother plant significantly impacts cardamom nurseries utilizing shoots, making it challenging to obtain large quantities of nursery transplants. Growth stimulants, such as vitamin B1 and Indole Butyric Acid (IBA), are required to enÂhance vegetative growth in plants. Vitamin B1 (IPI brand) is applied due to its ease of accessibility and cost-effectiveness. Meanwhile, IBA is utilized for its accessibility, stable chemical content, and prolonged efficacy. This research aims to determine the optimal concentration of vitamin B1, IBA, and their combination to enhance the growth of mother and tiller shoots of cardamom ex vitro. The research employed a two-factorial Randomized Complete Block Design, with vitamin B1 concentrations of 21.5% and 43% and IBA concentrations of 0.75 ppm and 150 ppm. The treatment V1I1 (vitamin B1 21.5% and IBA 75 ppm) on mother plant shoots maintained a survival rate of 67% up to 12 Weeks After Planting (WAP). The interaction between vitamins B1 and IBA exhibited no significant effect on all parameters of mother shoots and tillers; however, vitamin B1 significantly influenced the vegetative growth of cardamom mother shoots. Vitamin B1 at 43% produced a significantly higher number of leaves compared to 21.5%. Thus, vitamin B1 at 43% is recommended for cardamom propagation, while vitamin B1 at 21.5% has the potential to enhance the average growth of tiller shoots across all parameters.

The overuse of synthetic AB mix fertilizers in hydroponic systems raises concerns over chemical residues and long-term health risks. Incorporating liquid organic fertilizer (LOF) is a potential strategy to improve nutrient efficiency and enhance crop productivity. This study aimed to evaluate the application of liquid organic fertilizer (LOF) as a sustainable strategy to reduce AB mix dependency while maintaining crop growth and productivity. The experiment was arranged in a Completely Randomized Design (CRD) with five treatments: P1 (100% AB mix/control), P2 (25% LOF + 75% AB mix), P3 (50% LOF + 50% AB mix), P4 (75% LOF + 25% AB mix), and P5 (100% LOF). Plant growth and yield parameters were analyzed using Analysis of Variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT). The combination of LOF and AB mix significantly affected (P<0.05) plant height, root fresh weight, leaf number, and shoot fresh weight, but had no significant effect (P>0.05) on root length. All combinations of LOF and AB mix, including the 100% AB mix treatment, yielded statistically similar results across all measured parameters. However, the treatment with 75% LOF + 25% AB mix tended to produce the highest values, enhanced flavor, and did not reduce shelf life, whereas the 100% LOF treatment resulted in the lowest performance. These findings highlight the potential of LOF to substantially reduce synthetic input in hydroponic lettuce production, supporting more sustainable and health-conscious cultivation practices.
