Abstract

Edible film is a thin, edible film used as a food coating. The advantages of edible film include its biodegradability and its ability to maintain the quality and shelf life of the food product it covers. The objective of this study was to ascertain the impact of varying concentrations of sorbitol on the thickness, water vapor transmission rate, and microstructure of whey-chia seed edible film. The present study employed a Completely Randomized Design, comprising three distinct treatments, each with three replicates. The data obtained were analysed using Analysis of Variance, and if there were significant differences between treatments, these were followed by Duncan Multiple Range Test. The treatments incorporated the following: P1 (10% sorbitol), P2 (20% sorbitol), and P3 (30% sorbitol). The variables measured in this study were thickness, water vapor transmission rate and edible film microstructure. The findings demonstrated that the incorporation of sorbitol at varying concentrations elicited a highly significant effect (P<0.01) on the thickness of the edible film. However, the water vapor transmission rate test did not yield a significant difference (P>0.05). The mean thickness of the samples ranged from 0.0296 to 0.0303 mm, and the water vapor transmission rate ranged from 4.60 to 5.68 g/mm²/day. Microstructure analysis revealed that the incorporation of sorbitol enhanced the flexibility and uniformity of the distribution of the films at concentrations of 10% and 20%. However, at a concentration of 30%, the films exhibited increased rigidity and reduced flexibility. The utilization of a 20% sorbitol concentration was identified as the optimal treatment.

Abstract

The aim of this study was to compare the effectiveness of different brands of intramuscularly injected prostaglandin hormones on the speed and duration of estrus in Bali cattle. The study used 21 Bali cattle as subjects, divided into three treatment groups: P1 received 5 ml of Capriglandin, P2 received 5 ml of Lutalyse, and P3 received 2 ml of Juramate. The data collected included the speed and duration of estrus in hours. The results showed that for the speed of estrus onset, P1 required 69 hours, P2 56 hours, and P3 55 hours. Regarding the duration of estrus, P1 took 17 hours, P2 14 hours, and P3 13 hours. The findings indicate that the Juramate hormone resulted in the quickest onset of estrus, while the Capriglandin hormone led to a longer duration of estrus compared to the other hormones.

Abstract

The seedling phase is a critical stage in plant development, where the presence of plant-disturbing organisms (PDOs) can significantly reduce seedling quality and viability, particularly in rehabilitation species such as Samanea saman (Trembesi). This study aimed to analyze the intensity of pest and disease attacks, identify the types of PDOs involved, and describe the symptoms and signs of infestation observed in S. saman seedlings at the Tectona Nursery, KHDTK Bukit Soeharto, East Kalimantan. A simple random sampling method was applied to select 50 seedlings from a total population of 1,000 four-month-old individuals. Data collection was conducted through direct field observation of physical plant conditions, severity scoring, and documentation of symptoms and signs of biotic attack. The results showed that all sampled seedlings were affected, with an infestation intensity reaching 65.2%, classified as heavily infested. The observed symptoms included defoliation, foliar tissue loss (skeletonizing), leaf spots, leaf blight, and stem boring. Identified signs of attack included larvae from the order Lepidoptera and  mealybug (Pseudococcidae) and aphids, which are suspected to be the primary agents of tissue damage. These findings underscore the importance of monitoring pest and disease populations and implementing ecologically based Integrated Pest Management (IPM) strategies tailored to the nursery microclimate. Technical training and coordinated IPM implementation are essential to enhance seedling resilience and support the success of tropical forest rehabilitation.

Abstract

Interactions between biotic and abiotic components in ecosystems influence insect mortality, natality, and dispersal, thereby making species composition dynamic. The presence and abundance of arthropods in agricultural systems cannot be precisely predicted, as they are affected by numerous factors such as cropping practices, habitat type, plant age, and interspecific interactions among arthropods. This study aimed to examine the diversity, abundance, and community composition of arthropods across four agricultural habitat types: maize, soybean, weeds, and soil surface. Arthropod samples were collected through direct observation, sweep netting, and pitfall traps. The findings revealed that insects from the order Hemiptera had the highest abundance in comparison to other orders, with 51 individuals recorded on maize and 409 on soybean. In contrast, 244 insects were found on weeds, dominated by the order Diptera. On the soil surface, a total of 482 insects were collected, predominantly from the order Collembola. The Collembola order exhibited the lowest values in terms of relative diversity index (H′), dominance (D), and evenness (E) compared to other habitats. The Bray–Curtis similarity index between soybean and weed habitats was the highest (0.205), indicating a greater similarity in arthropod composition between these two habitats. Conversely, the lowest similarity value (0.043) was observed between soybean and soil surface habitats, suggesting a greater difference in arthropod community composition.

Abstract

Plant pathogens pose a significant challenge to the cultivation of red Jabon (Anthocephalus macrophyllus) seedlings. Notably, the fungi Rhizoctonia sp. and Pestalotia sp. are responsible for the destructive red leaf spot disease on Jabon leaves. To combat these fungal pathogens, the use of endophytic bacteria has emerged as a potential alternative. Endophytic bacteria can be isolated from various plant sources, although their effectiveness in controlling forest plant pathogens like Jabon has not been thoroughly explored. This study aimed to assess the potential of endophytic bacterial isolates obtained from Pteris ensiformis (Isolates APE15, APE22, APE33, and APE35) in controlling the growth of Rhizoctonia sp. and Pestalotia sp. through in vitro experiments. The antibiosis activity of the endophytic bacteria against the pathogenic fungi was evaluated using the dual culture method on PDA media. The results revealed that among the four endophytic bacterial isolates, APE35 exhibited the highest inhibitory effect on Rhizoctonia sp. (86.79%) and Pestalotia sp. (67.5%), while isolate APE22 only inhibited the growth of Pestalotia sp. (55%). In contrast, isolates APE15 and APE33 were unable to suppress either fungus. The antibiosis activity of APE35 and APE22 resulted in abnormal hyphal growth of the pathogenic fungi, characterized by shriveled, bent, dark-colored, and coiled hyphae. Physiological characterization of the endophytic bacteria revealed their ability to produce protease, cellulase, catalase, and phosphate-dissolving enzymes. Additionally, these bacteria exhibited a Gram-positive nature. This study provides valuable insights into the potential of endophytic bacterial isolates from P. ensiformis (APE35 and APE22) as biological control agents for Rhizoctonia sp. and Pestalotia sp., the causative agents of red Jabon leaf spot disease.

Abstract

Cocoa bean shells are a by-product of cocoa processing that contain bioactive compounds, particularly phenolics, with potential antioxidant activity. However, information on the effect of roasting time on the total phenolic content and antioxidant activity of fermented cocoa bean shells remains limited. Therefore, this study evaluated the effect of roasting time on the total phenolic content and antioxidant activity of fermented cocoa bean shells derived from Forastero cocoa beans (BR 25 variety) from Bolang Village, Enrekang Regency. A laboratory experiment was conducted using a drum roaster with a charge temperature of 135°C and roasting times of 10, 14, 18, and 22 min. Roasting time significantly affected total phenolic content and antioxidant activity. Roasting for 14 min produced the highest mean total phenolic content (30.1425 mg GAE/g extract) and the lowest IC50 value (83.69 ppm), although these results were not significantly different from those at 18 min. In contrast, the 10 and 22 min treatments showed lower total phenolic content and weaker antioxidant activity. These findings suggest that moderate roasting durations, particularly 14–18 min, were more favorable for maintaining the bioactive properties of cocoa bean shells.

Abstract

Chili is a commodity that is susceptible to damage, because of its highwater content, so it is necessary to carry out efficient and effective post-harvest actions through drying methods. Chili drying aims to reduce the water content of the dried material. The purpose of this study was to determine the pattern of water content reduction in bird’s eye chili and curly chili and the appropriate drying model to use for chili peppers. The average drying temperature inside the chamber ranger from 39 until 75 C and the total drying time was 21 hours from each treatment. The samples used were two types of chili peppers, namely bird’s eye chili and curly chili. The models whose suitability was evaluated were the Newton, Page, Handreson & Pabris models. The Page model showed the best performance in describing the drying behaviour of bird’s eye chili and curly chili, with R2 values of 0.9952 and 0.9971, respectively, which were higher than those obtained from the Newton and Henderson & Pabis model.

Abstract

Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) is a major polyphagous corn pest that has caused significant corn yield losses in Indonesia. Synthetic insecticides are still the primary choice, but their effectiveness in the field against S. frugiperda larval mortality is determined by the active ingredient and concentration used. This study aimed to evaluate the efficacy of several synthetic insecticides with the active ingredients cypermethrin, abamectin, and a combination of emamectin benzoate + chlorfenapyr on the mortality and time-response of S. frugiperda larvae on corn plants through laboratory testing. The study used a completely randomized design (CRD) with six treatments and four replicates. Larval mortality was observed at 6, 12, 24, 36, and 72 hours after treatment (HAT) and analyzed using the Kruskal-Wallis test at a significance level of 5% (α = 0.05). The results showed that corrected mortality at 72 HAT ranged from 85–100% across synthetic insecticide treatments, caused mortality in S. frugiperda larvae with symptoms such as decreased feeding activity, paralysis, body color changes, and shriveled death. The combination of emamectin benzoate + chlorfenapyr at the highest consentration caused 100% mortality within 12 HAT, whereas cypermethrin reached complete mortality at 24 HAT. Abamectin exhibited a more gradual increase in mortality up to 72 HAT. Numerically, the combination treatment demonstrated a more rapid mortality response than the single active ingredient treatments. These results indicate that all tested synthetic insecticides were effective against third instar S. frugiperda larvae, although differences in the speed of mortality response were observed among treatments.
