Abstract

Aloe vera is a tropical plant with significant potential to develop into a promising agricultural sector in Indonesia. To achieve high-quality Aloe vera harvests, it is important to pay attention to several growth conditions, especially plant care such as fertilization. This study aims to determine the effect of Photosynthetic Bacteria (PSB) fertilizer application and the effective dosage of PSB fertilizer for the growth of Aloe vera using vertical farming techniques. This research used a Non-Factorial Randomized Block Design (RBD), with treatment factors including: no application of PSB fertilizer (P0), PSB 5 ml/l (P1), PSB 15 ml/l (P2), and PSB 30 ml/l (P3). The research involved several stages of observation, including plant height, number of leaves, leaf width, leaf thickness, and root volume. The observed data were analyzed using ANOVA with the help of SPSS 26. If the ANOVA test showed a significant effect, further analysis was carried out using Duncan's Multiple Range Test (DMRT). The results showed that the application of PSB fertilizer had an effect on plant height (22.8 cm), leaf width (2.76 cm), number of leaves (7 leaves), leaf thickness (8.91 cm), and root volume (4 cm³). The best average treatment result for Aloe vera growth was obtained at a dosage of 15 ml/l (P2), indicating that Photosynthetic Bacteria (PSB) fertilizer at a dosage of 15 ml/l (P2) was sufficient to supply the necessary nutrients for the growth of Aloe vera.

Abstract

The Indonesian people are familiar with the herbaceous vegetable plant known as basil (Ocimum basilicum L.). The leaves of the basil plant are typically used to flavor cuisine and as fresh vegetables. This study set out to determine how applying liquid organic fertilizer from eco farming affected basil plants' ability to grow vegetatively (Ocimum basilicum L.) as well as the optimal dosage for this growth. August and September of 2023 saw the completion of this study. Using three treatments and five replications, the research employed a Randomized Block Design (RAK) methodology. Treatment A0 was the control, receiving no fertilizer; treatment A1 received 4 milliliters of eco-farm fertilizer; and treatment A2 received 6 milliliters of eco-farm fertilizer. The characteristics that need to be taken into account include plant height, number of branches, leaf area index, number of leaves, initial and final soil analysis, and chlorophyll content. The study data will be analyzed using statistical products and services solutions (SPSS) software version 25. The administration of 6 milliliters of eco-farm fertilizer to plants, or treatment A2, had a significant effect on the vegetative development of Ocinum basilicum L. basil plants, according to the research findings. Measurements of plant height are affected by a concentration of 6 ml. The highest average value for number of leaves is 30.00, while the highest average value for height is 39.60, the highest average value of 3.35 for leaf area index, and the highest average for leaf area index. 4.0 for number of branches.

Abstract

Soybeans contain many vitamins and minerals and are low in saturated fatty acids. Food ingredients derived from soybeans are also free from lactose, making them suitable for consumers who suffer from lactose intolerance. It is impossible to separate microgreens growth from their requirement for nutrients and water. Since microgreens are organic, chemical fertilizers are not used to them. Rice washing waste water is one substitute that can be utilized as fertilizer for microgreen plants. The purpose of this study is to ascertain the optimal concentration for maximizing the growth and yield of yellow soybean microgreens (Glycine max) and the impact of giving waste rice washing water on these microgreens. This study conducts quantitative research using an experimental design. A non-factorial randomized block design (RAK) was employed to collect the data, with concentration being the primary variable (P0: Control, P1: 50 ml rice washing water, P2: 100 ml rice washing water, P3: 150 ml rice washing water). Plant height, plant dry weight, plant wet weight, and chlorophyll levels are all significantly impacted by the availability of rice washing water, according to the research findings. The amount of leaves was unaffected by the presence of rice washing water. Plant height, dry weight, wet weight, and chlorophyll content can all be increased with P1 in as much as 50 milliliters of rice washing water.

Abstract

Soybean-based food business and population growth drive the increase in soybean consumption every year in Indonesia. Soybean varieties and liquid organic fertilizer applications can help overcome losses in soybean plant growth and productivity. This study used a randomized block design (RAK) with treatment consisting of 2 factors with 3 repetitions. Factor i liquid organic fertilizer (p), consists of 4 levels, namely: p0 = 0 ml, p1 = 20 ml, p2 = 40 ml, p3 = 60 ml. the 2nd factor cultivar (k), consists of 2 types, namely: k1 = cultivar detam 1, k2 = cultivar detam 3. The results showed that the response and effectiveness of the application of soybean peel poc and different cultivars did not significantly affect the vegetative growth of black soybean plants, but when viewed as a whole p3 (60 ml) gave the highest value on the parameters of leaf area index 21 hst, root nodules, chlorophyll a, and chlorophyll b content.

Abstract

Lettuce is a plant that is quite popular with the public. Not only does it have economic value but it also has quite high nutritional content. So one method used to maintain the stability of lettuce production on the market is by providing rice husk ash and monosodium glutamate (MSG). This research uses a non-factorial randomized block design (RAK) which consists of 5 levels, namely giving fertilizer without combination and giving combined fertilizer, namely P1 (Rice husk ash 100 grams/polybag), P2 (MSG 15 grams/polybag), P3 (Combination of rice husk ash and MSG with a dose ratio of 100 grams of rice husk ash : 15 grams of MSG), P4 (Combination of rice husk ash and MSG with a dose ratio of 75 grams of rice husk ash : 10 grams of MSG), P5 (Combination of rice husk ash and MSG with a dose ratio of 50 grams of rice husk ash: 5 grams of MSG). The study's findings demonstrated a significant impact on all parameters (plant height, number of leaves, leaf area index, and plant fresh weight) when a combination of rice husk ash and MSG was used. The results of testing the levels of chlorophyll a b and the total use of a combination of rice husk ash and MSG did not provide a significant effect. The most effective dose to increase the growth of lettuce plants was the use of a combination of rice husk ash and MSG with a level of P3 = 100 grams of rice husk ash: 15 grams of MSG.

Abstract

Peanuts (Arachis hypogea L.) are leguminous plants which are classified as the most important nuts after soybeans in Indonesia. Indonesia not only imports rice but also imports other food crops such as peanuts. By using NPK fertilizer and organic liquid palm oil waste fertilizer as treatments in this study, we hope to boost the productivity of peanut plants. A Factorial Randomized Group Design (RAK) was employed in the study, with two treatment components, namely: 1. Factors for administering liquid organic fertilizer from palm oil mill waste (P) with 4 levels, namely: P0= POC LCPKS 0 ml/polybag P1= POC LCPKS 100 ml/polybag P2= POC LCPKS 200ml/polybag P3= POC LCPKS 300 ml/polybag, 2. The NPK (K) fertilizer application factor consists of: K0= 0 mg / polybag K1 = 7.5 mg/polybag K2 = 15 mg/polybag K3= 22.5 mg/polybag. The findings of the research indicate that the vegetative growth of peanut plants (Arachis hypogaea L.) is significantly impacted by the availability of a combination of organic fertilizer made from liquid palm oil waste and NPK fertilizer. Nearly every metric, including plant height, leaf area index, and blossom count, is significantly impacted by the application of a blend of NPK fertilizer and organic fertilizer made from liquid palm oil waste. The P3K2, P0K1, P1K3, and P2K1 levels represent the best level attained depending on the supply of POC from palm oil waste and NPK fertilizer.

Abstract

Chives are a type of vegetable that comes from the lily family (bulb plants). This plant contains vitamins B and C, carotene and sulfur components. As time goes by, planting media not only uses soil media, but also uses air media, known as hydroponics. Good nutrition for hydroponic growth is one that contains micro and macro nutrients such as eco enzyme nutrients and fish waste. This research aims to determine the growth of chive plants (Allium tuberosum) in hydroponic growing media and to find out the most effective nutrients in increasing the growth of chives (Allium tuberosum) using hydroponic growing media. Data were collected using a non-factorial randomized block design (RAK), namely with nutritional treatment P1: AB Mix (5 ml/liter of air), P2: Eco enzyme + fish waste (5 ml/liter of air), P3: Eco enzyme (5 ml/liter of air), P4: fish waste (5 ml/liter of air). Based on the research results, P3 had a real influence on plant height at 1 and 2 MST with results of 9 cm at 1 MST and 13.33 cm at 2 MST. P1 had a real influence on plant height at 3.4 and 5 MST. The leaf area index parameter P1 had a significant effect at 5 MST with a result of 9.67 cm but had no real effect at 6 MST. The values of net assimilation rate, relative growth rate, and chlorophyll content were not significantly impacted by P1. The parameters of leaf area index, chlorophyll content, relative growth rate, and net assimilation rate were not significantly affected by P2, P3, or P4.
