Abstract

Background: Grape seeds are one part of the grape plant known to have antibacterial properties because they contain secondary metabolite compounds such as tannins and flavonoids. Previous studies have shown that grape seed extract has antibacterial activity against Streptococcus pyogenes, Streptococcus mutans, Propionibacterium acnes, and Staphylococcus epidermidis. However, testing for Enterococcus faecalis from 70% ethanol extract and n-hexane has not been found. This study aims to determine the antibacterial activity of n-hexane and 70% ethanol extract from grape seeds against E. faecalis bacteria. Methods: Extraction was carried out using the maceration method using two solvents: n-hexane and 70% ethanol. The antibacterial activity test used the disc diffusion method to determine the Diameter Inhibitory Power (DDH) value at extract concentrations of 5%, 10%, 20%, and 40%. Results: The results obtained showed that grape seed extract had antibacterial activity against E. faecalis, with the DDH value of n-hexane extract respectively being 9.70 mm, 10.36mm, 10.55mm, and 11.31 mm at concentrations of 5%, 10%, 20%, and 40%. The DDH value of the 70% ethanol extract was 11.20 mm, 12.34mm, 13.63mm, and 15.49 mm at concentrations of 5%, 10%, 20%, and 40%, respectively. Conclusions: These results indicate that n-hexane and 70% ethanol extract from grape seeds have antibacterial potential against E. faecalis.

Abstract

Background: Feed is a determining factor in the success of fish farming, but in some cases, fish feed on the market contains chemicals such as pesticides, heavy metals, and synthetic chemicals. Organic, safer, and readily available materials combine plant-based and animal ingredients such as cricket (Acheta domesticus) and coconut pulp. Cricket has a high nutritive value, especially protein content, and coconut pulp was potentially high in carbohydrate content. The study aims to determine the carbohydrate and protein content and the color, aroma, and density assessment of the combination of fermented coconut pulp flour and cricket flour. Methods: The design pattern was a 1-factor Completely Randomized Design (CRD) pattern with two repetitions of 3 treatments (A1, A2, and A3) of fermented coconut pulp flour and cricket flour. Feed is subjected to tests on carbohydrate and protein proximate levels and sensory assessments of its color, aroma, and texture. Results: The average carbohydrate content in formulas A1, A2, and A3 is 30.51%, 26.04%, and 28.45%, while the protein content is 10.64%, 20.88%, and 16.86%. ANOVA test results on color, aroma, and overall texture show significant differences in each fish feed formula. Conclusions: The highest level of sensory preference for color, aroma, and texture was observed in the combination of formula A2. Formula A1 is suitable for herbivorous fish, formula A2 for carnivorous fish, and formula A3 for omnivorous fish.

Abstract

Background: Increasing the productivity of Chili pepper plants can be done by pruning shoots and using trichotomous biofertilizer as an alternative to chemical fertilizers. This study aims to determine the effect of treating shoot pruning age and adding trichotomous doses on Chili pepper plant yields. Methods: This experiment used a Randomized Block Design with two factors. The first factor is the age of shoot pruning, which consists of 4 treatment levels, namely P0 = No pruning, P1 = shoot pruning 14 HST, P2 = shoot pruning 21 HST, P3 = shoot pruning 28 HST and trichotomous dose as the second factor consisting of 4 treatment levels, namely T0 = Without trichotomous, T1 = 600g/plant, T2 = 800 g/plant, and T3 = 1000 g/plant, so that 16 treatment combinations were obtained with three replications. Results: The results showed that the combination of pruning age treatment of 28 HST and trichotomous dose of 800g/plant produced the best number of flowers. A pruning age of 28 HST gave the best results on the number of leaves, leaf area, productive branches, total number of fruits per plant, and total fruit weight per plant. A trichotomous dose of 800 g/plant gave the best results on plant height, number of productive branches, total number of fruits per plant, and total fruit weight per plant. Conclusion: The pruning age of shoots and trichotomous doses affect the yield of Chili pepper plants.

Abstract

Background: Amorphophallus oncophyllus is a tuber plant that is beneficial for various industrial sectors, but in its cultivation, it is often affected by the pathogen Sclerotium rolfsii, requiring control measures. Control efforts can be carried out using a combination of the biological agent Trichoderma sp. and the plant pesticide made from bandotan leaf extract. The combined control application can be formulated in a solid granular form. Method: This research was conducted both in vitro and in vivo. In vitro, a Completely Randomized Design (RAL) was used with the combination of Trichoderma sp. and bandotan leaf extract, divided into four levels: 0% (TB0), 5% (TB5), 10% (TB10), and 15% (TB15). In vivo, a 2-factor RAL was applied. The first factor was the concentration of the rice flour carrier material in four levels: 0% (B1), 25% (B2), 50% (B3), and 75% (B4). The second factor was the storage duration of the granular formulation, consisting of 0 weeks (M1), 3 weeks (M2), and 5 weeks (M3). Result: The study's results showed that the granular combination of Trichoderma sp. and 10% bandotan leaf extract reduced S. rolfsii infection by 64.25% and stimulated the growth of porang plant height. Conclusion: The treatment with the granular combination of Trichoderma sp. and 10% bandotan leaf extract, adding 25% rice flour and a storage period of 0-3 weeks, showed the best effect on the porang plant seedlings.

Abstract

Background: Sweet corn (Zea mays saccharata Sturt) is a food plant from the family grass, and cultivating sweet corn is more profitable because it has high economic value on the market. The growth phase of sweet corn plants often experiences a decrease in production yields, even crop failure due to pest attacks. This research aims to determine the pest population and the level of Noctudiae pest attacks that attack sweet corn plants. The study was conducted on moorland in Pilanggot Hamlet, Wonokromo Village, Tikung District, Lamongan Regency, East Java, from May to July 2023. This research used a selected random sampling survey method, namely observations on five plots, and each plot contained 48 observed plants. Observations began when the sweet corn plants were 14 HST and carried out once a week, 10 observations with 7-day intervals, namely in the vegetative phase (14, 21, 28, 35, 42) and generative phase (49, 56, 63, 70 and 77 HST). ). The research results show that the highest population of Noctuidae pests is the armyworm (Spodoptera frugiperda), with as many as 63 individuals with a relative abundance of 54%. The Noctuidae pests found were the armyworm (Spodoptera frugiperda), moth (Spodoptera litura), and cob borer (Helicoverpa armigera). The highest attack percentage is 25%, but it is still mild.

Abstract

Background: Mangrove environments play an essential function in coastal tidal areas. Petengoran mangrove forest is located in Gebang village, Teluk Pandan district, Pesawaran, Lampung province. Describe the ecological and ethnocentric conditions of the Petengora mangrove forest in Gebang village, linked to mangrove vegetation to facilitate forest maintenance, community empowerment, and community impacts on Petengoran mangroves. Methods: This research uses the transect method at three stations with four plots. Each plot had an area of 10 x 10 m2. Ethnocentric data collection was conducted using questionnaires and field observations. Results: INP of Rhizopora mucronata was the highest (300%). The station's overall diversity level (H') is medium. The specific richness index (R) of all stations is low. All stations' uniformity index (E) is high, as shown by findings from community interviews on ethnocentric elements of Petengoran mangrove ecotourism. The environmental conditions of the mangrove forests are relatively clean and maintained, and the infrastructure and ecotourism infrastructure are pretty adequate. Conclusions: Petengora mangroves are managed by farmers who create nurseries and plantations. This area is a mangrove reserve. The mangrove forest is considered a traditional place, but surrounding communities do not have any unique traditions.

Abstract

Background: Seed-borne pathogens threaten plants because they can survive in seed tissues for long periods. Efforts that can be made include treating the seeds before planting them in the field with biological agents, one of which is Trichoderma sp. It is often found in soil with high organic matter, namely peat soil. This research aims to determine the potential of Trichoderma sp. isolates. from peat soil on pathogen infection of soybean seeds and germination of soybean seeds. Method: This research used a factorial method. The first factor was sick and healthy seeds, and the second was Trichoderma sp. isolates, consisting of TP1 and TP2. The control treatment uses the active ingredient fungicide mancozeb 80%. Seed treatment was carried out by soaking the seeds in a suspension of Trichoderma sp. with a spore density of 106 for 24 hours. The seeds were then tested using the growing-on-test method in sterile soil. Results: Identifying pathogens in soybean seeds found two genera, Aspergillus sp., and Fusarium sp., in the immersion treatment on Trichoderma sp isolates. TP2 gave the best results, where the lowest infection power was 46.6% for healthy seeds and 73.3% for symptomatic seeds. In addition, treatment with isolates of Trichoderma sp. TP2 can increase the germination capacity of soybean seeds by 60.0%. However, seed treatment with Trichoderma sp. does not affect soybean plant height and root length growth. Conclusion: The two isolates of Trichoderma sp. from peat soil positively protect seeds against soybean seed pathogens, seed germination, and soybean growth.
