Abstract

African Swine Fever (ASF) is among the most detrimental infectious viral diseases in pigs causing approximately 100% mortality. The disease was first reported about 83 years ago in Africa before spreading to Europe in 1957 and Asia in 2010. An adequate vaccine generally containing live attenuated virus isolates prepared in swine macrophages to control the disease is currently unavailable. Therefore, this study aimed to use murine neuroblastoma (N2a) cells, non-swine cell lines, to adapt African swine fever virus (ASFV) isolates for vaccine preparation. ASFV isolate called BL21 obtained from Bali and East Nusa Tenggara was previously propagated in swine macrophages. However, virus was currently adapted in the N2a cells to avoid unwanted issues associated with using swine macrophages, including microbial contamination, as well as technically laborious and ethical issues. The adapted BL21 was re-confirmed with quantitative polymerase chain reaction (q-PCR) and tested in vivo to examine the pathogenicity properties. The results showed that BL21 produced consistently and specifically positive q-PCR, killing experimental pigs with typical gross pathological changes of ASF. BL21 at a 10-3/mL dilution adapted in N2a cells showed similar antigenic properties causing the death of nearly 50% N2a cells in vitro and terminating all in vivo experimental pigs. In conclusion, the BL21 isolate reported in this study could be used as a vaccine candidate after more attenuation and particularly to determine a lethal dose of 50% (LD50) for future investigations.

Abstract

Bulung boni and bulung anggur are species of Caulerpa seaweeds commonly found along the coastline of Serangan Island, Bali. Although these species have been widely utilized in various ways, formal species identification of these two macroalgae in Bali had not been conducted prior to this study. This research aims to characterize the morphological structures of bulung boni and bulung anggur through detailed morphological examination. Identification keys and previous studies were used to assist in the morphological identification process. The findings revealed that bulung boni shares morphological characteristics with Caulerpa cylindracea, while bulung anggur is morphologically comparable to Caulerpa macrophysa. These results provide valuable insights into the species composition of seaweeds in the region and contribute to a better understanding of local biodiversity.

Abstract

Kayu tangi (Lagerstroemia sp.) is one of the medicinal plants that is often used traditionally by Balinese people for treating insomnia, diabetes, and dysentery. This study aims to determine the phylogenetic trees and the active compounds in Lagerstroemia tomentosa extract and its antioxidant activities. The methods used in molecular identification are DNA isolation, PCR, and DNA sequencing. The DNA sample was BLASTed to see its homology with the sequences in GenBank. These sequences were then used for phylogenetic tree analysis. The phytochemical analysis was done using the GC-MS method and the antioxidant activity test used the DPPH (1,1-diphenyl-2-picrylhydrazyl) after being reacted with the tested extract.  The results of molecular identification showed that the samples used were closely related to Lagerstroemia tomentosa species (MW044208.1). The antioxidant activity test results showed an IC50 of 2.1 ugml-1 which is included in the very strong category. The phytochemical test results showed that the most dominant compounds contained in the plant stem bark were furfural (AUC 8.54%), beta-sitosterol (AUC 6.00%), and gamma-sitosterol (AUC 3.81%). Based on PubChem data, these compounds have antioxidant and antimicrobial properties as well as insecticide and herbicide. In conclusion, kayu tangi is very close to  Lagerstroemia tomentosa and it’s potentially used as a medicine with strong antioxidant activities.

Abstract

Broiler chickens are a superior breed resulting from crossbreeding different chicken breeds with high productivity, especially in meat production. Chicken feces are the final product of the digestion process of feed and water consumed by livestock, in both liquid and solid forms. This study aims to determine the total plate count (TPC) of bacteria present in the feces of broiler chickens at the starter and finisher stages in Badung Regency. This research is an observational study using purposive stratified random sampling with a quantitative analysis approach. A total of 3 grams of broiler chicken feces were collected from each farm in Mengwi, Abiansemal, and Petang Districts. The total plate count of bacteria was determined using the culture method on Nutrient Agar media. The identified bacterial colonies had characteristics such as a clear white color, round shape, and glossy appearance. Data analysis was performed using variance analysis (ANOVA), and if significant differences were found (P<0.05), Duncan’s Multiple Range Test was conducted. Before analysis, the TPC data were transformed into log Y. The results showed that the TPC (log Y) in Mengwi District was 8.0608 CFU/g at 1-21 days of age and 7.6132 CFU/g at 22-35 days of age. In Abiansemal District, the values were 8.0928 CFU/g at 1-21 days and 7.7941 CFU/g at 22-35 days, while in Petang District, the values were 8.1476 CFU/g at 1-21 days and 7.9565 CFU/g at 22-35 days. Overall, the highest TPC was found in Petang District, followed by Abiansemal and Mengwi. It can be concluded that there is a significant difference (P<0.05) in the total plate count of bacteria in broiler chicken feces across the three districts based on the age groups of 1-21 days and 22-35 days. Further research is needed on broiler farm waste management following Indonesian National Standards (SNI) .

Abstract

The cattle slaughtering process at the Slaughterhouse (RPH) involves various occupational health and safety (OHS) hazards that require effective management. This study aims to identify potential OHS hazards and assess their risk levels at each stage of the cattle slaughtering process at the Denpasar City RPH. The research method used an observational approach with the Hazard Identification and Risk Assessment (HIRA) technique to analyze physical, biological, ergonomic, and psychosocial hazards. The results show that several work stages have a high-risk level (score ≥10), particularly during the slaughtering stage (physical risk score 10, biological score 12, ergonomic score 12) and the use of the restraining pen (physical risk score 16). Dominant hazards include exposure to zoonotic bacteria, injuries from sharp tools and animals, and musculoskeletal disorders due to non-ergonomic working postures. Psychosocial factors such as work stress also contributed significantly, with risk scores reaching 12 in several stages. Based on these findings, this study recommends implementing comprehensive mitigation measures, including: (1) improved use of standardized personal protective equipment (PPE), (2) regular OHS training on animal handling and tool use, (3) redesign of work facilities to be more ergonomic, (4) implementation of an ISO 45001-based OHS management system, and (5) a mental health program for workers. These recommendations are expected to reduce work accident rates and increase productivity at the Denpasar City RPH, while also serving as a reference for developing OHS policies in the livestock sector.

Abstract

Organically cultivated salak (Salacca zalacca) on dry land has limited production in Bali. Typically, fertilization is carried out using leaf litter or other organic fertilizers because soil fertility is low for salak plantations. The present study analyzed the effectiveness of an indigenous endomycorrhizal biofertilizer on the nutrient and total carbohydrate content of salak leaves and fruits. The study used a randomized block design with nine replicates. The treatment consisted of three levels, i.e., (1) fertilization with leaf litter only, as practiced by farmers and used as the control (C); (2) fertilization with an indigenous endomycorrhizal biofertilizer prototype (P); and (3) combined fertilization with leaf litter and an indigenous endomycorrhizal biofertilizer prototype (PM). Spores of indigenous endomycorrhizae from salak plantations were used to prepare the biofertilizer prototype. The results showed that the P and PM treatments provided beneficial results, such as: (1) significantly increasing chlorophyll content, relative water content of leaves, and the number and weight of fruits per tree; (2) improving fruit quality by increasing sweetness and weight per fruit; and (3) having a positive effect on water uptake and nutrient absorption, as indicated by high N and P contents in leaf tissue and high carbohydrate content in leaves.

Abstract

Red beetroot has been reported to possess various medicinal properties and antimicrobial activity. Therefore, this study aims to determine the compounds contained in the ethyl acetate extract of red beetroot pulp and evaluate its anti Escherichia coli effect. The extract was obtained by soaking the fruit in ethyl acetate, and then assessed for its components using GC-MS analysis. Antibacterial activity was tested using a disc diffusion assay. The results showed that the ethyl acetate extract of red beetroot pulp contained a total of 20 major compounds. These included ester of 1,3-benzenedicarboxylic acid and bis(2-ethylhexyl), 1,4-benzenedicarboxylic acid, and n-hexadecanoic acid. In the antibacterial test, the sample was highly effective against E. coli (IC 50 was 0,783 mg/mL). In addition, the diameter of the growth inhibition zone increased along with the extract concentration. These results suggest that the ethyl acetate extract of red beetroot pulp offers a natural antibacterial substitute to its synthetic equivalents.
