Abstract

Hydroponics offers a modern agricultural solution to overcome land limitations in urban settings. Despite its advantages, the system commonly relies on synthetic fertilizers like AB Mix, which are costly and may pose environmental risks. As a sustainable alternative, liquid organic fertilizer (POC) derived from Tithonia diversifolia, combined with nanobubble technology, may improve nutrient uptake efficiency in plants. This study aimed to evaluate the effect of combining AB Mix and nano POC on the growth of pakcoy (Brassica rapa L.) in a nanobubble-based hydroponic system. A Completely Randomized Design (CRD) was used with five treatments and five replicates: P1 (100% AB Mix), P2 (75% AB Mix + 25% nano POC), P3 (50% AB Mix + 50% nano POC), P4 (25% AB Mix + 75% nano POC), and P5 (100% nano POC). The measured variables were plant height, leaf number, leaf area, fresh weight, and dry weight. ANOVA and Duncan’s 5% test showed that P2 resulted in the best growth, while P5 had the lowest. These results indicate that nano POC is effective as a supplementary nutrient but cannot fully replace inorganic fertilizers. Further research is necessary to determine the optimal composition and its influence on plant quality.

Abstract

Pakcoy (Brassica rapa L.) production in Indonesia has declined due to limited land and reliance on costly inorganic fertilizer such as ABmix. Therefore, alternative fertilizer that are more efficient and enviromentally friendly are needed. This study aimed to eximine the effects of the liquid organic fertilizer (POC) made from gamal leaves (Gliricidia sepium Jacq. Kunth) using nano bubble technology on the growth and quality of pakcoy in a hydroponic system. A Completely Randomized Design (CRD) was used with five treatments: P1 (100% ABmix), P2 (75% ABmix +25% POC nano), P3 (50% ABmix+50% POC nano), P4 (25% ABmix+75% POC nano), and P5 (100% POC nano) each replicated five times. Observed parameters included plant height, leaf number and area, and fresh and dry weight. Result showed that treatment P3 gave the best performance in all observed variables. The balanced combination of ABmix and POC nano improve nutrient availability and photosynthetic efficiency, supporting optimal plant growth. Nano POC from gamal leaves shows potential as an alternative organic fertilizer in hydroponic systems, though further research is needed to understand its long-term effects and broader application.

Abstract

Cucumber (Cucumus sativus L.) is a horticultural crop with high water content, low calories, and potential benefits as an antibiotic, lipid-lowering agent, and antioxidant. This Plant has great potential for cultivation, as it can be marketed both domestically and internationally. However, cucumber production remains relatively low and has declined from 2022 to 2023. This decrease is caused by several factors, one of which is changing environmental conditions. Therefore, the plant's ability to adapt to different environmental conditions becomes a crucial factor in the effort to develop cucumber cultivation. Based on this, the present study was conducted to investigate the morphological characteristics of cucumber leaves under different environmental conditions. This research was conducted from September 2024 to January 2025 in two different locations, namely Kota Padang and Kamang Magek. The method used in this study was a Completely Randomized Design (CRD) with 2 treatments and 20 replications. The data obtained were analyzed using a t-test at a 5% significance level. The results showed that there were significant differences in leaf length and the number of leaf vein branches between the two research locations. The average leaf length in Kota Padang was higher, at 12.21 cm, compared to Kamang Magek, which only reached 10.42 cm. In contrast, the average number of leaf vein branches in Kamang Magek was higher, at 14.65, compared to Kota Padang, which was only 13.3. Meanwhile, no significant differences were found in leaf width and petiole length between the two locations.

Abstract

Cucumber (Cucumis sativus L.) is a high-value horticultural crop widely used as fresh vegetables, processed food ingredients, and cosmetic products. In addition, cucumber contains important nutrients for health, such as vitamin C, vitamin K, and various essential minerals. As a plant with many benefits, cucumber is greatly influenced by climatic conditions, which can directly affect productivity and harvest quality. Based on this, a study on the phenology of cucumber plants under two different climatic conditions was conducted. This study used an experimental method involving 20 cucumber plants, with two location treatments and two replications. The observed parameters included the time of flower emergence and flowering duration. The study was conducted from September to December 2024 at two locations, Kamang Magek and Padang. The data were analyzed using a t-test with a significance level of 5%. The results of the study showed significant phenological differences between cucumber plants grown in Kamang Magek and Padang. Plants in Kamang Magek went through generative phases earlier, marked by earlier flower emergence, which occurred on day 25.4 after planting, compared to day 29.45 in Padang. The flowering duration in Kamang Magek was also shorter, lasting 7.9 days, compared to 10.55 days in Padang. These findings indicate that differences in climatic conditions between the two locations have a significant impact on the phenological development of cucumber plants.

Abstract

Hydroponics, a farming technique using nutrient-enriched water, has been widely practiced due to its suitability for limited agricultural land. One of the key factors affecting hydroponic efficiency is the nutrient blend, with AB Mix and liquid organic fertilizer playing a crucial role. This study aims to evaluate the potential of nanotechnology-based nutrient solution in hydroponic to enhance nutrient absorption and improve plant growth in different vegetable species. Five vegetable species, which include red lettuce, red spinach, green spinach, pakcoy, and kailan, were selected to assess the interaction between nutrient composition and vegetable species. A study with factorial design was conducted using a randomized complete block design (RCBD). The primary factor was the fertilizer composition and the secondary factor was the type of vegetable. The treatments consisted of Control (Well water + AB Mix), P1 (Nanotechnology water + 100% AB Mix), P2 (Nanotechnology water + 25% nanotechnology liquid organic fertilizer + 75% AB Mix), P3 (Nanotechnology water + 50% nanotechnology liquid organic fertilizer + 50% AB Mix), P4 (Nanotechnology water + 75% nanotechnology liquid organic fertilizer + 25% AB Mix), and P5 (Nanotechnology water + 100% nanotechnology liquid organic fertilizer). Growth parameters measured included plant height, fresh weight, dry weight, number of leaves, and leaf area. Data were evaluated using a two-way ANOVA to assess the effects of fertilizer composition and vegetable type, followed by a 5% DMRT test for mean comparison. The findings indicated that the use of liquid organic fertilizer technology influenced plant growth. The most optimal average growth was recorded in the P2 treatment (a combination of nanotechnology water, 25% nanotechnology liquid organic fertilizer, and 75% AB Mix), while the least favorable result was observed in P5 (nanotechnology water combined with 100% nanotechnology liquid organic fertilizer).

Abstract

The agricultural sector cannot be separated from the role of inorganic fertilizers to support plant growth, as is the case with rice cultivation. Farmers' dependence on using inorganic fertilizers has led to decreased soil fertility and damage to natural resources. One way to overcome this is to implement organic farming. Organic cultivation in this research uses the SRI (System of Rice Intensification) method, while inorganic cultivation follows conventional methods from local communities. The aim of the research was to determine the effect of giving Trichoderma asperellum on rice plant height in organic and inorganic cultivation. The research was carried out in September-December 2022 in Jorong Galo gandang, Nagari III Koto, Tanah Datar Regency, Biological Research Laboratory, and Plant Physiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Padang State University. This type of research is experimental. The research was structured using a Randomized Block Design, with 4 treatments, namely; O (Organic) OT (Organic + Trichoderma asperellum), A (Inorganic), AT (Inorganic + Trichoderma asperellum) and 5 repetitions. Observational data was analyzed by analysis of variance (ANOVA) using the SPSS application. If there are differences, continue with the DNMRT test (Duncan's New Multiple Range Test). The results showed that giving Trichoderma asperellum had no significant effect on rice plant height in organic and inorganic cultivation. Because the high rainfall at the research location caused the nutrients from each experimental plot to be washed away by the water.
