Abstract

Ruminal tympany is a major digestive disorder that limits productivity and increases mortality in smallholder goat production systems, particularly in rural areas with limited veterinary support. This community service study aimed to improve farmers’ knowledge and awareness of ruminal tympany through a participatory extension approach. The program applied a one-group pretest–posttest quasi-experimental design involving 30 smallholder goat farmers in Panerokan Village, Jambi Province, Indonesia. The intervention combined lectures, interactive group discussions, and hands-on demonstrations focusing on disease identification, risk factors, preventive feeding management, and basic on-farm response strategies. Farmers’ knowledge was measured using structured questionnaires administered before and after the intervention. The results showed a substantial increase in knowledge, with mean scores improving from 45% in the pretest to 77% in the posttest across all assessed indicators. The novelty of this program lies in its practice-based and context-specific extension model that integrates scientific knowledge with local feeding practices. The findings suggest that participatory extension interventions can effectively strengthen farmers’ capacity for early detection and prevention of ruminal tympany, thereby contributing to more sustainable and resilient smallholder goat farming systems when supported by continued mentoring and follow-up initiatives.

Abstract

Mangroves are coastal forest ecosystems commonly distributed in tropical and subtropical regions and play a vital role in maintaining coastal environmental stability. The mangrove ecosystem in Pangkal Babu, Tungkal 1 Village, Tungkal Ilir District, West Tanjung Jabung Regency, Jambi, functions as an ecological buffer for the coastal zone; however, scientific information on its species composition and diversity remains limited. This study aimed to identify and document the mangrove species present in the area. Field surveys and direct observations were conducted to characterize mangrove vegetation by recording and photographing each species and examining diagnostic features, including root structure, stem morphology, leaf shape, and fruit characteristics. The results showed that the Pangkal Babu mangrove ecosystem is composed of several true mangrove species, each exhibiting distinctive morphological traits: Acanthus ilicifolius with thick spiny leaves; Nypa fruticans with large pinnate leaves and clustered fruits; Sonneratia alba with erect pneumatophores and subglobose fruits; Avicennia alba with salt-excreting leaves and pencil-shaped pneumatophores; Bruguiera cylindrica with knee roots and cylindrical propagules; Rhizophora mucronata with mucronate leaves and large stilt roots; Rhizophora apiculata with black-spotted leaves and shorter propagules; and Xylocarpus granatum with compound leaves and large spherical fruits resembling cannonballs. These findings provide essential baseline data for future conservation efforts, habitat monitoring, and sustainable coastal management initiatives in Tungkal Ilir and the surrounding regions.

Abstract

Nanotechnology represents an innovative strategy to enhance the penetration and efficacy of active compounds in topical formulations. This study aimed to formulate and evaluate the physicochemical properties of Boswellic Acid (BA) nano-gel with varying concentrations of the active ingredient using a Carbopol 940-based matrix. The research methodology commenced with particle size reduction of BA through an ultrasonication technique for 150 minutes, followed by its integration into a gel matrix containing propylene glycol and glycerin as humectants. The pharmaceutical quality evaluation included organoleptic, homogeneity, pH, viscosity, spreadability, and drying time tests. The results demonstrated that all formulations (NgBA-F1, NgBA-F2, and NgBA-F3) exhibited excellent homogeneity with a constant pH value of 5, ensuring compatibility with skin physiology. The viscosity of all formulas reached 3000 cPa, meeting the ideal standards, although the concentration of the active ingredient significantly influenced the color intensity of the preparation. However, mechanical testing revealed a spreadability of 3 cm, which did not meet the ideal criteria of 5–7 cm due to high viscosity. Furthermore, the addition of BA extended the drying time to a range of 26.27–28.17 seconds compared to the gel base (15.65 seconds). This study concludes that the Boswellic Acid nano-gel formulation met the physical quality standards for pH, viscosity, and homogeneity, but requires further optimization of the base components to improve spreadability characteristics and drying time kinetics.

Abstract

Limited knowledge among smallholder goat farmers regarding appropriate antibiotic use may contribute to the emergence of antimicrobial resistance in livestock-associated bacteria. This study aimed to identify bacterial isolates and evaluate antibiotic resistance patterns of bacteria obtained from fecal and nasal mucosal swabs of goats in Pematang Gajah. Samples were collected from nine goats with three repeated examinations. Bacterial identification was performed using Gram staining followed by standard biochemical tests. The results showed that 8 of 9 isolates (≈90%) from fecal swabs exhibited biochemical characteristics consistent with Escherichia coli, including Indole (+), MR (+), VP (−), Citrate (−), TSIA A/A with gas production, positive motility, and metallic green sheen on EMB agar. A total of 7 of 9 isolates (≈76%) from nasal mucosal swabs demonstrated typical characteristics of Staphylococcus aureus, namely Gram-positive cocci, catalase-positive, coagulase-positive, mannitol fermentation positive, and β-hemolysis. Antibiotic susceptibility testing conducted on one isolate of E. coli and one isolate of S. aureus with three replications revealed the highest inhibition zones in E. coli against enrofloxacin (23.33 ± 0.58 mm) and gentamicin (21.33 ± 0.58 mm), categorized as sensitive, while high resistance was observed against tylosin (8.33 ± 0.58 mm) and penicillin–streptomycin (9.33 ± 0.58 mm). Staphylococcus aureus isolates showed high sensitivity to enrofloxacin (24.33 ± 0.58 mm), tylosin and gentamicin (22.33 ± 0.58 mm), but resistance to penicillin–streptomycin and ampicillin. These findings indicate variability in antimicrobial susceptibility among goat-associated bacteria and highlight the importance of susceptibility-based antibiotic selection to reduce antimicrobial resistance risk.
