Abstract

Anthracnose caused by Colletotrichum spp. leads to significant losses in bird’s eye chili (Capsicum frutescens L.) production, including reduced fruit quality, lower yield, and increased production costs. Although synthetic pesticides are widely used for disease management, their prolonged application raises concerns regarding environmental sustainability and food safety. This study aimed to evaluate the antifungal potential of citronella essential oil, in both free and nano-encapsulated forms, against Colletotrichum spp. Compared to the previous studies, this work uniquely evaluates and compares nano-encapsulated and non-encapsulated citronella essential oil against anthracnose in bird’s eye chili. The experiment was arranged in a Completely Randomized Design (CRD) with treatments consisting of citronella essential oil at concentrations of 0.125% and 0.063%, either encapsulated or non-encapsulated, tested under in vivo and in vitro conditions. Parameters observed were incubation period, disease intensity, inhibition percentage, colony appearance, and hyphal morphology. Data were analyzed using ANOVA at a 5% significance level, followed by Duncan’s Multiple Range Test (DMRT) when significant differences were detected. Application of 0.125% citronella essential oil effectively delayed incubation (6.05 DAI), resulting in a disease intensity of 45%, and achieved the highest in vitro inhibition (92.21%) until 10 DAI, outperforming Propineb 70 WP and other treatments. Colony morphology remained generally similar, but notable differences in hyphal fate were observed, including lysis, shrinkage, curling, and unbranched growth. These findings indicate that citronella essential oil is a promising natural candidate to reduce reliance on Propineb 70 WP. However, further field-scale evaluations are needed.

Abstract

Spodoptera frugiperda is a newly emerging pest species attacking maize crops by damaging the plant whorl, thereby disrupting the growth point of the plant. The use of biological control agents, particularly the bioinsecticide Bacillus thuringiensis, represents one of the alternative strategies to manage S. frugiperda infestations. This study aimed to investigate the morphological characteristics and developmental changes of S. frugiperda following the application of the bioinsecticide B. thuringiensis. The experiment was conducted at the Basic Laboratory, Faculty of Agriculture, Winaya Mukti University, from August to September 2023. The experimental design employed a Completely Randomized Design (CRD) consisting of five treatments with six replications. The concentrations of the B. thuringiensis bioinsecticide were as follows: A = 0.00 g/L of water (control); B = 0.125 g/L of water; C = 0.25 g/L of water; D = 0.50 g/L of water; and E = 1.00 g/L of water. The results showed that the concentration of B. thuringiensis at 1.00 g/L significantly affected the morphology and development of S. frugiperda, as indicated by increased feed consumption loss, average larval weight, larval length, head capsule width, and larval mortality, which reached up to 90.00%. In addition, this concentration significantly influenced the percentage of pupae formation and the percentage of adult emergence.

Abstract

Tomatoes (Solanum lycopersicum) are a horticultural commodity with high economic value and are widely cultivated in Indonesia. However, tomato productivity is often limited by pest and disease attacks. This study aims to identify insect species and analyze the intensity of diseases that attack tomato plants. The research methodology used was quantitative descriptive research involving two main components, namely identification in the laboratory and direct observation in the field. The research findings showed that there were four types of arthropods with various roles in the tomato ecosystem, namely Spiders (Lycosa sp.) classified as Natural Enemies; Ants (Odontoponera sp.) classified as Predators; Grasshoppers (Oxya chinensis) classified as Pests; Moths (Order lepidoptera) classified as Pests. In addition to pests, brown spot disease (Alternaria solani) was also found. The results of observations of the intensity of disease attacks showed differences in each treatment, the intensity of disease attacks was highest in the treatment without mulch and suckering compared to other treatments.

Abstract

Riau Province has significant potential for tomato production, with harvested area increasing from 44 ha (2021) to 45 ha (2022) and productivity reaching 4.48 tons/ha. However, weed competition is a major obstacle to yield optimization. This study aimed to evaluate the effectiveness of the interaction of palm kernel shell mulch and rice husk mulch in suppressing weeds and increasing tomato yields. The method used was a Completely Randomized Design (CRD) experiment, involving two factors: palm kernel shell mulch thickness (0 cm, 2 cm, 4 cm) and rice husk mulch thickness (0 cm, 0.75 cm, 1.5 cm), each replicated three times. Observation parameters included plant height, stem diameter, number of productive branches, fruit weight per plant, total harvested fruit, and wet and dry weed weight. The results showed that the combination of 4 cm palm shell mulch and 1.5 cm rice husk (C2S2) provided the best results, including the highest plant height (67.67 cm), the highest fruit weight per plant (1,175.10 g), the highest number of fruits (31.33 fruits), and the lowest dry weight of weeds (41.67 g). The interaction of the two mulch types significantly affected plant growth and weed suppression, although not significantly for some parameters such as stem diameter and number of productive branches. Organic mulch also helped improve soil structure, reduce water evaporation, and provide additional nutrients for plants.

Abstract

Shallots are a horticultural commodity in Indonesia with high economic value. This spice vegetable plays a very strategic role. The demand and demand for shallots always increase every year, but production has not been matched. This study aims to determine the effect of Trichoderma sp dosage on the growth and yield of shallots. This research was conducted in rice fields in Pekandangan village, Indramayu Regency, from June to August 2025. The experimental design used in this study was a Randomized Block Design (RBD) consisting of five treatments, each replicated five times. The five Trichoderma sp. dosage treatments were T0=0, T1=10kg/ha, T2=20kg/ha, T3=30kg/ha, T4=40kg/ha. The result of the study of various doses of Trichoderma sp showed a significant effect on the parameters of plant height, number of leaves, tuber diameter and root length, the highest in the T3 treatment, namely 30kg/ha. However there was no significant effect on the yield parameters of shallots wet and dry tuber weight.

Abstract

Marginal soils are characterized by low nutrient availability, which adversely affects crop productivity. The incorporation of organic materials and cultivation techniques plays an important role in maintaining soil health and crop yield. This study aimed to  evaluate the effects of photosynthetic bacterial fertilizers and the push-pull system cultivation technique. The research was conducted in Banjaran Village, Purbalingga Regency, utilizing a completely randomized block design. Treatments tested included S0 (control), S1 (50 mL/2L), and S2 (100 mL/2L), as well as P0 (control), P1 (lemongrass), and P2 (peanuts). Each treatment was replicated three times and analyzed using ANOVA, with Duncan's Multiple Range Test (DMRT) (α=5%) applied for significant differences. The observed variables included fresh plant weight, leaf area, fresh root weight, age of male flowers, and chlorophyll a levels. The results indicate that the application of photosynthetic bacteria significantly affects the fresh weight of the plants and the age of male flowers. However, there is no significant effect on leaf area, fresh root weight, and chlorophyll a levels. The push-pull system cultivation technique significantly affects chlorophyll a levels, although no significant differences were found in fresh plant weight, leaf area, fresh root weight, and age of male flowers.

Abstract

Purple eggplant productivity is still relatively low and has not been able to meet market demand, so efforts are needed to increase production through fertilization. The study aims to determine the growth and yield of purple eggplant plants at various doses of NPK fertilizer and coconut fiber POC concentration. The study used a Completely Randomized Design (CRD) with 2 factors + 1 control with 3 replications. The first factor was the dose of NPK fertilizer, namely 10, 13, and 16 g/plant. The second factor was the concentration of coconut fiber POC, namely 50, 75, and 100 mL/L. The control used NPK fertilizer at a dose of 20 g/plant. Data were analyzed using a 5% analysis of variance (ANOVA) and continued with a 5% DMRT test. Differences between treatments and controls were analyzed using the Orthogonal Contrast Test. The results showed that there was an interaction between plant height (42 days after planting) and flowering time. Application of NPK fertilizer at a dose of 13g/plant produced the best results in terms of fruit length and fruit weight per fruit. Meanwhile, application of coconut fiber POC at a concentration of 75 mL/L produced the best results in terms of plant height at 28 days after planting, number of leaves (21 and 28 days after planting), stem diameter (42 days after planting), fruit diameter, fresh fruit weight per plant, and harvest index. The combination of treatments was significantly better than the control in plant height (21 days after planting), number of leaves (21 days after planting), flowering time, number of eggplant fruits per plant, fruit diameter, fresh fruit weight per plant, and harvest index.

Abstract

Suboptimal peanut productivity requires more effective and sustainable fertilization strategies. This study aimed to evaluate the effects of combined SP-36 fertilizer and cow manure applications and to determine the most effective dosage combination for improving peanut growth and yield. The experiment was conducted in Ulubalang Village, Salomekko Subdistrict, Bone Regency, South Sulawesi Province, from May to August 2025. A Randomized Block Design (RBD) with six treatments and three replications, namely P0 (control), KS20 (cow manure 20 tons/ha), SP50 (SP-36 at 50 kg/ha), SP100 (SP-36 at 100 kg/ha), KS20 + SP50 (cow manure + SP-36 at 50 kg/ha), and KS20 + SP100 (cow manure + SP-36 at 100 kg/ha). Data were analyzed using ANOVA and a 5% LSD post-hoc test. The results showed that the fertilizer combination treatments influenced plant height at 30 days after sowing, the number of pods, the percentage of filled pods, and seed weight per plant. The best treatment was obtained with the KS20 + SP100 combination, yielding a plant height of 21.11 cm, 19.61 pods, a percentage of filled pods of 19.61%, and a seed weight of 18.94 g. Thus, the application of organic and inorganic fertilizers proved to be more effective than single-fertilizer application in increasing peanut productivity.

Abstract

The problem of land degradation and the high price of inorganic fertilizers are factors that cause the production of curly chilies to be less than optimal. One effort to overcome this is the use of organic fertilizers such as chicken, cow, and goat manure as a source of nutrition for plants. This study aims to determine which type and dose of manure is optimal for the growth and yield of cayenne pepper plants. The study was conducted in Purwaharja Village, Purwaharja City, Banjar City, West Java from September 2024 to January 2025. This study used a factorial Randomized Block Design (RAK). The first factor is the type of manure consisting of 6 levels including K1 (chicken manure), K2 (cow manure), K3 (goat manure), K4 (chicken + cow manure), K5 (chicken + goat manure), and K6 (cow + goat manure). The second factor is the dose of manure consisting of 3 levels including D1 (150 g polybag-1), D2 (200 g polybag-1), and D3 (250 g polybag-1). The type of chicken and goat manure is optimal for plant height (60.53 cm) and number of leaves (44 strands), the type of chicken, goat, chicken + cow, chicken + goat, cow + goat manure is optimal for leaf color 4 MST (4), and the type of chicken manure is optimal for the beginning of flowering (36 HST). The dose of manure is 250 g polybag-1 optimal for plant height (49.41 cm), number of leaves (55 strands), and leaf color 4 MST (4), and a dose of 200 g polybag-1 optimal for leaf color 4 MST (4). There is an interaction between the treatment of type and dose of manure on leaf color 8 MST.

Abstract

Fruit flies (Diptera: Tephritidae) are major pests of horticultural crops reducing fruit quality and limiting export opportunities due to quarantine restrictions in many importing countries. Developing environmentally sustainable pest management strategies is therefore essential to enhance the competitiveness of Indonesian horticultural products. This study aimed to identify fruit fly parasitoid on snake fruits, level of parasitism and to find a feasible mass-rearing method under laboratory conditions. Fruit fly parasitoid was collected from snake fruits in Magelang, Central Java and Sleman, Special Region of Yogyakarta followed by laboratory rearing, morphological and molecular identification and comparison of mass rearing methods using natural host fruits and modified artificial diet. Morphological and molecular identification showed that parasitoid parasitized fruit fly on snake fruits was identified as Fopius arisanus (Hymenoptera: Braconidae). F. arisanus associating with fruit fly that was morphologically identified as Bactrocera carambolae (Diptera: Tephritidae). The average field parasitism rate of F. arisanus on fruit fly infesting snake fruits was 27.38%, with sex ratio of males and females were 43.89% and 56.11%). Mass rearing method using natural host fruits (snake fruits) showed successfully parasitizing on fruit fly eggs and resulted sex ratio of males and females were 42.1% and 57.9%, whereas rearing method using the modified artificial host showed no parasitizing on fruit fly eggs and should be further studied and developed. These findings support F. arisanus as a potential biological control for fruit fly management programs in Indonesia.
