Abstract Colibacillosis is one of the most problematic issues in the boiler industry. However, the antibiotic overuse has induced Escherichia coli resistance so that other alternative to reduce colibacillosis is needed. One of the alternatives is using aloe vera (Aloe barbadensis Miller), which has been widely used as an antibacterial agent. This study aims to isolate and identify E. coli from the broiler drinking water source and test the aloe vera antibacterial activity against it. Escherichia coli were isolated from well in three broiler farms in Moyudan District, Sleman, Yogyakarta that previously had colibacillosis. Escherichia coli were isolated using eosin methylene blue (EMB) agar and the metallic sheen colony was tested to confirm the biochemist reaction. The pure isolate of E. coli was used in the aloe vera inhibition test using Muller Hinton agar (MHA) by a Well Diffusion method. Aloe vera was processed using aquades and ethanol 70%. The aquades infusion was diluted into 12.5%, 25%, 50%, 75%, and 100% and the extract ethanol 70% was diluted into 10%, 12.5, %, 25%, 40%, and 50%. The bacterial identification showed that one of three samples contained E. coli which was then used for inhibition test. The result showed no inhibition zone in the aquades infusion while ethanol extract showed an inhibition zone in concentration 25%, 40%, and 50% of aloe vera extract with a diameter 19.5 mm, 24 mm, and 25 mm. It can be concluded that aloe vera ethanol extract has inhibitory activity against E. coli in poultry drinking water with a minimum concentration of 25%.  Keywords: Aloe vera; Broiler drinking water; Escherichia coli; Inhibitory activity   Abstrak  Colibacilosis masih menjadi permasalahan dalam industri broiler. Penggunaan antibiotik berlebihan telah menyebabkan resistensi sehingga perlu alternatif lain. Salah satu alternatif adalah menggunakan bahan alami seperti adalah lidah buaya (Aloe barbadensis Miller) yang memilliki aktivitas antibakteri. Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi E. coli dari sumber air minum di kandang broiler serta menguji aktivitas inhibisi lidah buaya terhadap bakteri tersebut. Air yang digunakan sebagai sumber E. coli berasal dari sumur di tiga peternakan broiler di Kecamatan Moyudan, Sleman, Yogyakarta yang memiliki riwayat infeksi colibacilosis. Bakteri E. coli diisolasi menggunakan media eosin methylene blue (EMB) dan diuji sifat biokimia untuk mengkonfirmasi sifat bakteri E. coli. Isolat murni E. coli digunakan pada uji daya hambat bakteri dengan metode difusi sumuran menggunakan media Muller Hinton Agar (MHA). Lidah buaya diproses menggunakan aquades dan ethanol 70%. Infusa aquades diencerkan menjadi konsentrasi 12,5%, 25%, 50%, 75%, dan 100% dan ekstrak ethanol 70% diencerkan menjadi 10%, 12., %, 25%, 40%, dan 50%.  Hasil isolasi menunjukan bahwa satu sumber air dari sumur di Desa Kolowenang mengandung E. coli yang kemudian digunakan pada pengujian daya hambat. Hasil pengujian menunjukan tidak ada daya hambat yang terbentuk pada infusa aquades sedangkan ekstrak etanol lidah buaya 25%, 40%, dan 50% menunjukan adanya zona hambat sebesar 19,5 mm, 24 mm, dan 25 mm berturut-turut. Ekstrak etanol lidah buaya pada penelitian ini memiliki kemampuan menghambat pertumbuhan E. coli yang bersumber dari air minum broiler dengan konsentrasi terendah 25%.

The coagulation–flocculation–sedimentation process is widely used for removal of suspended solids and water turbidity reduction. The most common coagulants used to conduct this process are aluminum sulfate and ferric sulfate. In this paper, the use of Aloe vera as a natural-based coagulant for drinking water treatment was tested. The bio-coagulant was used in two different forms: powder as well as liquid; the latter was extracted with distilled water used as a solvent. The obtained results showed that the use of the natural coagulant (Aloe vera) in both powder (AV-Powder) and liquid (AV-H2O) forms reduced the water turbidity at natural pH by 28.23% and 87.84%, respectively. Moreover, it was found that the use of the two previous forms of bio-coagulant for drinking water treatment had no significant influence on the following three parameters: pH, alkalinity, and hardness. The study of the effect of pH on the process performance using Aloe vera as a bio-coagulant demonstrated that the maximum turbidity removal efficiency accounted for 53.53% and 88.23% using AV-Powder and AV-H2O, respectively, at optimal pH 6.

Background and Aim: Staphylococcus pyoderma is a common problem in dogs that need a novel treatment rather than antibiotic therapy. The aim of this study was to investigate the therapeutic efficacy, anti-inflammatory, and antioxidative properties of Aloe vera (Aloe barbadensis) gel ointment on dogs' Staphylococcus pyoderma compared to gentamicin ointment. Materials and Methods: The inhibition zone of A. vera extract 20% and 40% and gentamicin 1% against Staphylococcus aureus was determined on well diffusion agar. Twenty Baladi local breed dogs were used as control negative group before intradermal inoculation with 105 CFU S. aureus. The animals were classified into four equal groups, control positive group without treatment (n=5), treated groups by 20% A. vera gel ointment (n=5), 40% A. vera gel ointment (n=5), and gentamicin ointment 1% (n=5). Topical application of A. vera and gentamicin ointments was carried out twice daily for 2 weeks until complete healing of dogs' pyoderma. Clinical evaluation was recorded. Inflammatory, oxidant, and antioxidant parameters were measured in serum. Results: The inhibition zone of A. vera extracts 20% and 40% was 19 mm and 23 mm, respectively, while gentamicin 1% was 18 mm. The half maximal inhibitory concentration (of A. vera 20% and 40% were 13.70 with R2=0.98. Dogs' pyoderma treated with A. vera gel ointment 20% and 40% were more likely to have low haptoglobin and tumor necrosis factor-α concentrations than gentamicin 1% ([odds ratio [OR]=4.6; 95% confidence interval [CI]=1.31-17.40; p<0.05]; [OR=5.2; 95% CI=1.04-22.30; p<0.05]), respectively. Conclusion: It seems evident that A. vera has therapeutic effect, antibacterial, and anti-inflammatory effects against dogs' staphylococcal pyoderma than gentamicin that would support its further use rather than antibiotics in one health arena.
