Abstract

Terrain analysis on land can be done through field activities or remote sensing. The development of aerial photography technology through drones can be used to identify land conditions, especially on narrow land, and requires large-scale maps. Terrain characterization can use a Digital Elevation Model (DEM) generated through aerial photography with drone vehicles. This study aimed to determine the research location's topographic characteristics, scale, and class of map geometry accuracy. The research location is in the Eastern Region of Padjadjaran Jatinangor University, Hegarmanah Village, Jatinangor District, part of the Cikeruh Sub Das. The method used is a descriptive survey method and quantitative data analysis. The results showed that the topographic characteristics of the study location had an elevation of 715 – 747 m above sea level and a flat slope class (0 – 3%) – steep (>60%), which was dominated by a steep slope class (26 – 40%) on 55 land units. The aerial photography used meets the standard of map accuracy class at a scale of 1:2,500 class 3

Abstract

The use of compound inorganic fertilizers in plant cultivation systems is on the rise because of their practicality, more comprehensive and homogeneous nutrient availability, and potential to reduce production costs. Different combinations of compound fertilizer products can generate a variety of responses in terms of plant growth. The aim of this investigation was to assess how plants responded to the components of their results, specifically the variations in two distinct compositions of compound fertilizers. This investigation divided 60 experimental sites into two groups, each using two distinct types of compound fertilizers. The macronutrient content of the compound fertilizers (NK and NP), distinguished them. This study employed nine treatments, which included a control (without fertilizer treatment), conventional NPK fertilizer, a combination of NPK fertilizers (3/4, and 1) doses with (1/2, 3/4, 1 and 1) doses of compound fertilizer, and a randomized block design Each treatment was repeated three times. The results of this study suggest that the application of compound fertilizer with two distinct compositions has a substantially different effect than the control treatment. In comparison to compound fertilizers with a higher potassium content, which have a yield component value of RAE 134%, the application of compound fertilizers with a higher phosphorus content can provide a higher yield component value of RAE 127.92%. The function of applying potassium-containing nutrients can produce better outcomes for corn plant than those with higher phosforus content, making it an interesting study that should be investigated further in the future

Abstract

The Nutrient Film Technique (NFT) in hydroponic crop production systems generally uses chemical nutrient solutions to provide plant nutrients, even though biofertilizer inoculation can enrich liquid nutrients. The purpose of this experiment was to observe the effect of liquid biofertilizers applied with chemical nutrient solutions on changes in the acidity and electrical conductivity of nutrient solutions, as well as the growth and yields of pak choy (Brassica rapa L.) grown in Nutrient Film Technique. This experiment was set up in a completely randomized design with three nutrient solution treatments and eight replications. The treatments included the application of 100% chemical nutrient solution (control), and 75% and 50% concentrations of chemical nutrient solution enriched with a consortium biofertilizer. The results showed that at the end of the experiment, the acidity of all nutrient solutions increased, but their electrical conductivity (EC) was reduced. The fresh weight of pak choy shoots in medium B (75% chemical nutrition with biofertilizers) was 34% lower than the control (A), although statistically it was not significant. However, 50% chemical nutrition with biofertilizers produced the same shoot weight as the recommended dose of chemical nutrition. Moreover, 75% chemical nutrient with biofertilizers increased root weight. This current experiment verified that a reduced concentration of nutrient solution enriched with biofertilizer can be used to maintain the yield of pak choy grown in NFT.

Abstract

Lead pollution in rice fields in Rancaekek is attributed to the inadequate processing of waste from the textile industry. This phenomenon engenders a decline in soil fertility, thereby posing a threat to both food quality and agricultural sustainability. Employing N Bio-Organomineral fertilizer stands as one of the measures aimed at ameliorating the quality of rice fields afflicted by heavy metal contamination, particularly lead (Pb). This study seeks to elucidate the impact of N Bio-Organomineral fertilizer on various soil parameters, namely pH, NO3 - , soil organic carbon (C-organic), soil Pb solubility, and plant Pb uptake. The research was conducted in Linggar Village, Rancaekek, spanning from December 2019 to April 2020. Utilizing a Randomized Block Design as the experimental setup consisted of eight treatments with four replications, including: a control (0), urea at 250 kg/ha, and varying doses of the fertilizer at 250, 500, 750, 1000, 1250, and 1500 kg/ha. N Bio-Organomineral fertilizer represents a modified form of nitrogen fertilizer comprising urea, zeolite, activated charcoal, and compost enriched with Bacillus subtilis, formulated in a ratio of 60:20:10:10, respectively. The findings indicate that the application of N Bio-Organomineral fertilizer leads to an augmentation in soil NO3 - and C-organic content, while concurrently mitigating the uptake of Pb by plants. Among the treatments, the application of 500 kg/ha of N Bio-Organomineral fertilizer emerges as the most efficacious in enhancing soil NO3 - and C-organic content, as well as diminishing Pb accumulation in plants

Abstract

Application of Biofertilizer and Azolla (Azolla pinnata) to Improve Several Soil Chemical Properties, Growth and Yield of Rice Plants (Oryza sativa L.). Efforts to increase agricultural production through intensification programs cannot be separated from using artificial chemical fertilizers. However, the continuous use of artificial chemical fertilizers must be balanced by providing organic matter to avoid a deficiency of land-available nutrients, organic matter, and beneficial microorganisms. Using biofertilizers and Azolla can help provide nutrients and improve the biological properties of the soil. This research aimed to determine the effect of the interaction of biofertilizer and Azolla in increasing soil N and lowland rice yields. This research was conducted in a greenhouse, experimental garden, Ciparanje, Jatinangor, Faculty of Agriculture, Universitas Padjadjaran. The experimental design used was a factorial randomized block design with two factors. The first factor, the dose of Azolla pinnata (A), consisted of 4 levels: without Azolla, Azolla 10 t ha-1, Azolla 20 t ha-1, and Azolla 30 t ha-1. In comparison, the second was the dose of solid biofertilizer (H), which consisted of 3 levels, without biofertilizer, 12.5 kg ha-1 biofertilizer, and 25 kg ha-1 biofertilizer, repeated three times. The results of the study showed that there was no interaction between biofertilizer and A. pinata on total soil N, plant N concentration, soil C/N ratio, and lowland rice (Oryza sativa L.) yields; however, the application of Azolla 30 t ha-1 increase the number of productive tillers. The application of biofertilizer and Azolla has yet to increase rice plants' Dry Harvested Grain (DHG). However, the DHG tends to increase by 9.58% and 9.95%, respectively, compared to the control

Abstract

Plant productivity is influenced by soil quality and availability of plant nutrients. Soil conditioner can improve soil quality by enhancing soil properties. Both macro and micronutrients can be fulfilled through application of nutrient solution containing macro and micronutrients and biofertilizer. This experiment was conducted from at experimental field of the Faculty of Agriculture, Universitas Padjadjaran to test the combination of soil conditioner, NPK fertilizer, nutrient solution (NS), and biofertilizer (BF) effects on soil biological and chemical properties and red chili growth. The experiment was designed using a Randomized Block Design with seven treatments and four replications. The treatments consisted of control, combination of NPK and NS with a dose of 0, 6, and 12 kg.ha-1 BF contained Azotobacter sp., Azospirillum sp., and Pseudomonas sp.. The doses used for a single application were 15 gplant-1 NPK and 300 mLplant-1 NS. Manure was applied to the control treatment and soil conditioner to the other treatments as a basic fertilizer at a dosage of 4 ton.ha-1. The results showed that the combination of soil conditioner, NPK fertilizer, nutrient solution, and biofertilizer had significant effects on soil biological properties and red chili growth, but didn’t show significant effect on soil chemical properties. The combination of soil conditioner + NPK + 12 kg.ha-1 BF increased soil fungal population (113,4 x 103 CFU.mL-1) and bacterial population (599,5 x 108 CFU.mL-1). Meanwhile, the combination of soil conditioner + NS + 6 kg.ha-1 BF increased plant height (60,48 cm).

Abstract

This study investigates the microbial populations during different coffee fermentation processes and their impact on coffee quality. Bacillus, Pseudomonas, and endophytic populations in coffee beans undergoing natural saccharic and natural lactic fermentation remained unchanged compared to fresh coffee beans. However, a notable increase in Bacillus population occurred in honey saccharic fermentation, possibly attributed to the high sugar content in the mucilage, supporting bacterial growth. Additionally, the introduction of Lactobacillus and Saccharomyces during fermentation enhanced sugar consumption and influenced the final coffee quality, particularly aroma profile and nutritional composition. Varietal differences were observed, with Bacillus population decreasing slightly post-fermentation, especially in honey saccharic and natural lactic processes. This decline may be attributed to the dominance of Saccharomyces and Lactobacillus, antagonistic to Bacillus, and the fermentation conditions leading to decreased pH, unfavorable for Bacillus. These findings highlight the intricate microbial interactions and their implications for coffee fermentation and quality.
