Abstract

Background: The use of aqueous extracts from certain plants in controlling weeds is gaining attention in eco-friendly agriculture due to their allelopathic activity. One of the plants that has been investigated as a potential bioherbicide for controlling various weeds is Lantana camara L. Its extract has been tested on several non-targeted plants and has been shown to inhibit their germination. This study aimed to examine the effect of bioherbicide (aqueous extract of Lantana camara L. leaves) on rice (Oryza sativa L. cv. Cempo Merah) as a non-targeted plant. Methods: This experimental study used a completely randomized design with three replications. Concentration series of the aqueous extracts from L. camara L. leaves (0%, 25%, 50%, 75%, and 100%) were tested on rice seeds that were germinated on petri dishes for 14 days. Results: The results showed that the aqueous extract of L. camara L. leaves had a phytotoxic effect on germination and early growth of rice (Oryza sativa L. cv. Cempo Merah). Conclusions: The highest concentration exhibited the greatest phytotoxicity. Allelopathy chemicals in L. camara L. leaves were responsible for these effects.

Abstract

Background: Aspergillus flavus is a fungus that produces aflatoxin, a toxic compound that can contaminate food products, especially nuts. The impact caused by A. flavus causes significant losses for peanut-producing countries in cases of international trade. A. flavus infection in peanuts causes physical changes and quality, as well as a decrease in seed germination. Environmentally friendly control efforts for A. flavus can be carried out by utilizing biological agents such as Trichoderma spp. This study aims to evaluate the ability of T. harzianum and T. asperellum to inhibit the growth of A. flavus. This study also evaluates bio-priming methods enriched with Trichoderma spp. to optimize peanut seed germination. Methods: The research used a factorial Completely Randomized Design (CRD) of 2 factors. The first factor is the isolate species Trichoderma spp. namely T. harzianum (T1), T. asperellum (T2), and Control (T0), namely A. flavus without biological control treatment. The second factor is the application method, which includes the bio-priming (B1) and bio-matrixpriming (B2) methods. Each treatment combination was repeated 4 times, and the number of seeds used was five in each unit. Results: T. harzianum showed the highest inhibitory ability against A. flavus in the in vitro test, namely 49%. Bio-priming treatment containing the active ingredient T. harzianum is the best treatment for increasing peanut germination by 95%. Conclusions: The research results showed that bio-priming treatment with the active ingredient T. harzianum increased the germination rate significantly compared to other treatments.

Abstract

Background: Shallots (Allium ascalonicum L.) are a commodity that contributes significantly to the country's foreign exchange, holding high economic value. Rabbit urine, when processed into liquid organic fertilizer, provides plants with the macro and micro nutrients they need. This study aims to investigate the interaction between liquid organic fertilizer concentrations derived from rabbit urine and three varieties on the growth and yield of shallots. Method: The method chosen for this study was a Completely Randomized Design (CRD) consisting of two treatment factors: three varieties of shallots (Bima Brebes, Bauji, and Tajuk) and five levels of rabbit urine LOF concentration (0, 100, 250, 400, and 550 ml/L). and obtained 15 combinations (V1, V2, V3 and K1, K2, K3, K4, K5). Results: Significant interaction occurred in the number of leaves aged 7–14 HST. The Bima variety showed the best vegetative growth, while the Tajuk variety produced the highest number of bulbs. A concentration of 550 ml/l gave the highest results in plant length, number of leaves, and wet and dry weight of the stover. Conclusion: Rabbit urine LOF concentration of 550 ml/l is effective in increasing the growth and yield of shallots, especially in the Bima variety.

Abstract

Background: Corn (Zea mays L.) is the most essential food commodity after rice and a secondary crop. The demand for Corn in Indonesia is currently relatively high, yet its production has been declining. To increase Corn production, improvements in cultivation techniques are necessary. One such method is optimizing assimilate distribution through leaf defoliation, as well as creating optimal growing conditions through fertilization. Fertilization should be balanced by using both inorganic and organic fertilizers. In this study, NPK Phonska and Guano fertilizers were used. Methods: This study employed a factorial randomized complete block design (RCBD) with two factors. The first factor was the level of leaf defoliation below the cob, consisting of three levels: no defoliation (D1), defoliation leaving three leaves (D2), and defoliation leaving two leaves (D3). The second factor was the substitution of NPK Phonska and guano fertilizers with five levels: 100% NPK Phonska (P1), 75% NPK Phonska + 25% Guano (P2), 50% NPK Phonska + 50% Guano (P3), 25% NPK Phonska + 75% Guano (P4), and 100% Guano (P5). Results: The study's results showed that defoliation, leaving two leaves below the cob, combined with the application of 7 tons/ha of guano fertilizer without the addition of NPK, increased cob weight, cob length, and dry kernel weight per plant. Additionally, the independent application of 7 tons/ha of guano fertilizer without NPK Phonska significantly increased cob diameter. Conclusions: The combination treatment of defoliation, leaving two leaves below the cob, and the application of 7 tons/ha of guano fertilizer without the addition of NPK had the most favorable effect on Corn production.

Abstract

Background: Paenibacillus polymyxa is a potent antagonist that can be utilized as a biological agent. The use of biological agents has gained interest among farmers, but their application in liquid formulations has not consistently maintained the optimal stability and viability of microorganisms. One promising approach to overcome this problem is bioencapsulation, which is a method of wrapping biological agents to protect bacteria in the soil and increase their efficiency. This study aims to assess the encapsulation efficiency, measure the viability of microorganisms in the beads, and determine the difference in swelling power of beads made with various concentrations of calcium chloride (CaCl2) as a binding agent. Method: Beads were produced using the extrusion method by combining Paenibacillus polymyxa suspension, sodium alginate suspension, and adding CaCl2 at concentrations of 1%, 3%, and 5%. Results: The results showed that different CaCl2 concentrations can affect the viability of Paenibacillus polymyxa in beads. Beads made with CaCl2 at 3% concentration were the best results in the encapsulation efficiency test compared to beads made with 1% and 5% CaCl2 binders. In comparison, beads with 3% and 5% CaCl2 concentrations were able to maintain the viability of microorganisms at a higher level and for a longer time than beads using CaCl2 at 1% concentration. The decrease in viability and swelling power of the beads is thought to be caused by the carrier material used and the storage conditions. Conclusion: Bead treatment with 3% calcium chloride concentration was the best treatment for encapsulation efficiency in absorbing Paenibacillus polymyxa, amounting to 98.21%.

Abstract

Background: The need for e-encyclopedia development due to the low utilization of ICT in developing e-encyclopedias makes students lazy and less interested in studying the morphological diversity of Pteridophyta based on local potential. Therefore, the development of Canvaflipedia addresses the above problems as a learning medium that is more interactive and easily accessible to students, and can be applied in the PBL model of learning. This study aims to design and test the validity of an electronic encyclopedia related to the morphological diversity of Pteridophyta based on local potential in PBL learning. Methods: The type of research used is an R&D study with a 4D (Define, Design, Develop, and Disseminate) model, but the research only reached the development stage, which focused on validity testing by three validators using a validation sheet as a research instrument. Data was collected by compiling the results of the validation sheet and analyzed descriptively and quantitatively to interpret the validity results obtained. Results: The findings of the material expert validation test analysis showed a very valid category with an average value of 91.11%. By contrast, the results of the media expert validation test analysis showed a very valid category with an average value of 87.70%. Conclusions: Based on these results, the Canvaflipedia developed is very valid for application in PBL learning.

Abstract

Background: The oxeye snail (Turbo argyrostoma) is a marine gastropod commonly harvested by coastal communities for consumption. Intensive and unregulated harvesting may lead to population decline, raising concerns for ecosystem stability and resource sustainability. This activity directly reduces the population of T. argyrostoma in coastal waters. This study aims to determine the abundance and the correlation between the length-weight and condition factors of T. argyrostoma in the waters of Batam, Riau Islands. Method: This study was performed from September to October 2024. Sampling was conducted at three locations: Kajang Island, Piring Island, and Layang Island. The sampling method conducted was purposive sampling. Water quality measurements were carried out in situ. Abundance was determined based on the number of individuals per unit area. Morphometric data were collected by measuring the body dimensions of T. argyrostoma using digital callipers. Next, the length-weight relationship was analysed using linear regression to determine growth patterns. Results: The aquatic environment met the quality standards set by the Minister of Environment, as outlined in Decree No. 51/2004. The highest abundance of T. argyrostoma was observed at Kajang Island (1.37 ind/m²). Morphometric measurements showed mean shell length (SL) of 39 ± 4.83 mm, weight (W) of 21.3 ± 4.58 g, and shell width (SW) of 30.3 ± 3.25 mm in Layang Island samples. A positive length–weight relationship was identified at all stations (r = 0.73, 0.45, 0.78) with allometric growth coefficient (b) values indicating growth patterns. Condition factors (K and Wr) varied across locations: 6.766 and 70.340 at Piring Island; 6.518 and 103.984 at Kajang Island; and 6.229 and 101.037 at Layang Island, respectively. Conclusion: A positive length–weight relationship was observed at all sites, and variation in condition factors suggests differing ecological pressures. The low Wr value at Piring Island may indicate environmental stress or higher predation pressure.
