Abstract

Heavy metals rank high among the hazardous contaminants in the fresh produce of plant origin, originating from growing media and contaminated air environments. Plants absorb heavy metals depending on the availability of heavy metal ions in the soil and anthropogenic activities using agrochemicals. The entry of heavy metals into the human body through the tropic level can cause various chronic diseases; so regular monitoring of the presence of heavy metal contaminants in fresh products of plant origin is critical. Testing for heavy metal contaminants in plant tissues using an atomic absorption spectrophotometer – flame. The research results showed that the heavy metal contaminant Cd was not detected in the pre-cultivated agricultural land. In plant tissues, Pb in the pre-cultivated land was detected at 49,271 ± 0,423 mg kg–1, while Cu in the pre-cultivated land was 87,369 ± 0,867 mg kg–1, and in soybean seed tissue 12,571 ± 0,698 mg kg–1. Based on research results for Cu contaminants, show that a THQ value of 0.001 means that it does not have the potential to suffer chronic non-carcinogenic health consequences. This situation is reinforced by the THQ < RfD value means that stakeholders to be vigilant about reducing Cu contaminants on agricultural land, by consistently implementing good agricultural practices.

Abstract

Curly chili is a horticultural product with high nutritional value, greatly demanded as a distinctive complement or flavoring for dishes due to its unique taste and aroma. Despite the increasing demand for chilies, production has not followed suit, mainly due to disruption caused by viruses transmitted by Bemisia tabaci and Thrips sp. This study aimed to investigate the effect of tobacco extract on the growth and development of viral diseases in curly chili. Conducted at Kwangsang Village, Jumapolo District, Karanganyar Regency, from September to December 2021, the research was designed using a completely randomized block design, with treatment doses of tobacco extract at 0 mL/L, 1 mL/L, 2 mL/L, 3 mL/L, and 4 mL/L, labeled J0, J1, J2, J3, and J4, respectively. The results indicated that the variabels, i.e. plant height, number of leaves, number of fruits, and fruit weight per plant, were significantly affected by the tobacco extract. Similarly, the disease incidence and severity of viral infection were significantly influenced by the tobacco extract application. The yield decrease in curly chili was attributed to virus infection by Bemisia tabaci and Thrips sp., which caused chlorosis and mosaic symptoms on the leaves. Although the affected plants did not die, they experienced a yield reduction. The application of tobacco extract significantly reduced the percentage of incidence and severityof virus infection on curly chili. The highest disease incidence was 35.42% (J0) and disease severity was 70.92% (J0), while the lowest disease incidence was 14.58% (J4) and disease severity was 20.58% (J4).

Abstract

Organic waste management is becoming increasingly important in responding to current global environmental challenges. In this context, this community service aims to explore the potential for using organic waste as a substrate for hydroponic media in building a greener agricultural future in a sustainable system. The use of organic waste as a substrate for hydroponic media has great potential in supporting plant growth, because it contains available N, P2O5, K2O and C-organic nutrients which are sufficient for plant growth and development. Plants grown in organic waste-based substrates show comparable or even better growth compared to plants grown in conventional substrates. The use of organic waste in hydroponic farming also has a positive impact on the environment. More effective management of organic waste helps reduce environmental pollution and greenhouse gas emissions. This community service program has also succeeded in increasing public awareness and knowledge about organic waste management and hydroponic technology. Thus, the use of organic waste as a substrate for hydroponic media offers great potential in improving organic waste management, increasing agricultural productivity, and reducing negative impacts on the environment. This activity makes a real contribution to building a more sustainable agricultural future and contributes to global efforts in facing increasingly complex environmental challenges.

Abstract

The rice plant (Oryza sativa L.) is the main food commodity in Indonesia, but its production has not shown a significant increase. To increase rice productivity, especially in rainfed areas, it is necessary to optimize the use of nutrients such as nitrogen and phosphorus. Facing the challenges of low fertility and limited water availability, endophytic bacterial consortia can help increase nutrient availability and plant growth. The aim of this research was to determine the effect of nitrogen and phosphorus doses and their interactions on the growth and yield of the Mekongga rice variety in rainfed land where a consortium of endophytic bacteria was applied. The treatments carried out were designed as a factorial experiment in a Randomized Completely Block Design, namely the Nitrogen factor consisting of four dose levels: 0, 92, 184, 276 kg/ha and the Phosphorus factor consisting of four dose levels: 0, 72, 144, 216 kg/ha with three repetitions. The results showed that differences in nitrogen doses had a significant effect on the number of grains per panicle of rice plants, but did not have a significant effect on other growth and yield parameters of rice plants. Varying phosphorus doses and combinations of nitrogen and phosphorus doses did not have a significant effect on all growth and yield parameters of the Mekongga rice variety.

Abstract

The valorization of agro-food waste represents a promising pathway toward sustainable bio-based materials. This study aimed to formulate a fermentation medium from rice panicle straw (merang) and watermelon rind for producing eco-friendly SCOBY (Symbiotic Culture of Bacteria and Yeast) biofilm. The waste materials were thermally extracted without filtration to retain active solids and subsequently fermented with lactic acid bacteria for 14 days. The fermentation broth was enriched with soybean flour as a nitrogen source and Ziziphus mauritiana leaf extract as an antioxidant additive. Phytochemical screening was conducted using colorimetric reactions analyzed through chromaticity coordinates for flavonoids and grayscale intensity for alkaloids. SCOBY growth was evaluated by measuring biofilm thickness, wet and dry weight, tensile strength, and elongation at break. The results revealed that the combination of these residues provided sufficient nutrients and bioactive compounds to support SCOBY development. The best treatment produced a biofilm with 4.51 mm thickness, 17.49 g wet weight, 3.86 g dry weight, 43.11 MPa tensile strength, and 6.66% elongation. Colorimetric evaluation showed a red chromaticity spectrum for flavonoid presence (dominant wavelength 620 – 625 nm, purity 81.04%), and a clear white grayscale range (220 – 240) for alkaloids. In conclusion, this formulation offers a simple, low-cost approach to converting agricultural waste into functional biofilms. Further investigations are recommended to evaluate the shelf life and potential of liquid SCOBY as a plant immunomodulator and biofilm as organic packaging.

Abstract

Physically, development of plants will experience physical changes, one of which is the height of the plant. Monitoring activities will certainly be effective with the help of technology. The utilization of IoT is a technological breakthrough in that multitasking can be used for monitoring and sharing data simultaneously. So to support growth observation activities, this study aims to implement an IoT-based prototype modeling tool with ultrasonic sensors embedded in the NodeMCU microcontroller which is integrated with the database server. Modeling is used to analyze the workings of measuring plant height, involving case studies of mustard plant growth which are interpreted descriptively based on sensor capture height which is compared with expert-validated original observations. The research method used is quantitative data processing in the form of comparison charts. The data obtained in real-time by accessing the website address is available so that the data records are stored in the database server for as much as 1071 data for 33 days with 5 storage sessions a day. The results of the IoT prototype modeling managed to capture altitude data, with a comparison presentation between the height of the original plant and the sensor capture of 54.7% valid data without any difference. The conclusion from this study, there are still quite a lot of differences in the comparison of the two. This is due to modeling with improper sensor placement, so that it is detected outside the boundaries between predetermined objects.

Abstract

The rapid deterioration of soybean seeds during storage severely limits the availability of high-quality planting stock. Seed invigoration, specifically through matriconditioning, a technique involving controlled hydration using a moist solid medium, offers a method to improve the germination capacity of aged seeds. This study was thus designed to ascertain the optimal dosage of vermicompost utilization as a matriconditioning agent for improving the physiological quality of soybean seeds. Vermicompost, the product of organic matter decomposition, provides a comprehensive nutrient profile that may enhance seed physiological quality. The research aimed to determine the optimal vermicompost dosage for improving soybean seed physiological quality. A two-factor Factorial Completely Randomized Design (CRD) with four replications was employed. The factors were the priming ratio seed (g): vermicompost (g): water (ml) at four levels R0​ (control), R1​ (12:14:12), R2​ (12:14:13), R3​ (12:14:14) and priming duration four levels: D0​ (control), D1​ (6 hours), D2​ (12 hours), D3​ (18 hours). The experiment used Argomulyo cultivar seeds (initial germination 70-79%). Results indicated that the most effective invigoration treatment utilized the vermicompost priming ratio of 12:14:12 and an incubation period of 18 hours at ambient conditions (25±2 ºC).
