Abstract

Environmental factors are important in influencing plant growth and development. In adapting to environmental factors, plants will respond through physiology, morphology and anatomy. One of the fastest aspects in responding to changes in environmental factors is leaf morphology, because leaves are the most sensitive and responsive organ to environmental changes. This literature review was written with the aim of knowing the morphological response of leaves to environmental factors. The method used is literature review by reviewing 25 articles selected to obtain 5 national journals, 8 international journals, and 4 indexed journals so that there are 17 articles. Based on the identification of 17 scientific articles, it was found that plants change aspects of leaf morphology such as leaf size, leaf shape, leaf thickness, and leaf colour as a form of adaptation to environmental factors such as climatic factors such as sunlight intensity, humidity, rainfall, and temperature, drought, altitude, anthropogenic environmental factors, water factors and soil factors.

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

Nagari Talang Babungo in Solok Regency, West Sumatra, exhibits significant potential for sugarcane (Saccharum officinarum L.) cultivation. While the current average sugarcane yield in this area is 70 tons/ha, the maximum potential could reach 150 tons/ha. This research aims to enhance sugarcane productivity through the application of biochar, produced from agricultural waste including bagasse, as a soil amendment. Biochar has been shown to improve soil fertility and nitrogen use efficiency in plants. To capitalize on this potential, a comprehensive mentoring program has been implemented to enhance farmers' knowledge and skills in sugarcane cultivation and post-harvest processing techniques. Results demonstrate that biochar application can increase sugarcane biomass production by up to 23% and improve nitrogen use efficiency by up to 35%. Moreover, the socialization and training initiatives have significantly improved farmers' understanding, with average participant scores rising from 42.3 to 85.7 after program completion. The integration of biochar application and effective training not only boosts sugarcane productivity but also supports local economic development and agricultural sustainability in Nagari Talang Babungo. This program aligns with local government policies aimed at enhancing food security and agricultural productivity, thus contributing to the region's overall development strategy.

Abstract

Kale (Brassica oleracea var. acephala) cultivated in hydroponic systems commonly relies on inorganic AB Mix nutrients, which raises sustainability concerns. This study evaluated the potential of nano-technology liquid organic fertilizers (nano-POC) derived from Sargassum, Gliricidia sepium (gamal leaves) and Tithonia diversifolia as partial substitutes for AB Mix in hydroponic kale cultivation. The experiment was conducted using different substitution formulations, and plant growth responses were assessed based on morphological and biomass-related parameters. The results showed that partial substitution of AB Mix with nano-POC maintained superior growth performance compared to full organic application. The formulation P3S (50% AB Mix + 50% Sargassum nano-POC) produced the most balanced and consistent growth responses, reaching a plant height of 22.5 cm, an average of seven leaves and a dry weight of 0.17 g, and showed no significant difference from the 100% AB Mix control. In contrast, the exclusive use of nano-POC resulted in significant declines across all growth indicators. Multivariate analysis using Principal Component Analysis (PCA) confirmed the stability and consistency of the optimal treatment across growth parameters. These findings indicate that nano-POC functions effectively as a complementary nutrient source in hydroponic systems. Integrating nano-technology liquid organic fertilizers through partial substitution strategies offers a sustainable approach to reducing dependence on synthetic fertilizers while maintaining hydroponic kale productivity.

Abstract

Phaleria macrocarpa (Scheff.) Boerl., referred to as Mahkota Dewa, is a valuable medicinal plant with significant economic importance, requiring effective propagation methods to enhance its cultivation. Grafting is a frequently utilized technique, and its effectiveness is affected by the kind of growth medium used. This study aimed to evaluate the effect of different planting media on root growth of grafted Mahkota Dewa. The research was carried out between January and March 2026 in Lubuk Minturun, employing a Completely Randomized Design (CRD) with three different treatments: soil (P0), sawdust (P1), and cocopeat (P2), each consisting of six replications. The parameters monitored included the number of roots, root length, and dry weight of roots. Data were evaluated by using analysis of variance (ANOVA). The findings showed that the type of growth medium did not have a significant impact (p>0.05) on any of the root growth parameters measured. These results imply that alternative mediums like sawdust and cocopeat can serve as replacements for soil without notably hindering root growth in grafted P. macrocarpa.
