ABSTRAK. Penelitian ini bertujuan mengetahui jenis bakteri Gram negatif pada uterus sapi Aceh yang mengalami kawin berulang. Dalam penelitian ini digunakan enam ekor sapi Aceh betina yang terdiri atas tiga ekor sapi fertil (K1) dan tiga ekor yang mengalami kawin berulang (K2, repeat breeding, RB). Pengambilan sampel bakteri dalam uterus sapi dilakukan dengan menggunakan swab steril yang disimpan dalam media nutrient broth (NB) untuk isolasi dan identifikasi jenis bakterinya. Berdasarkan hasil penelitian, baik K1 dan K2, positif terinfeksi bakteri dan diperoleh 16 isolat bakteri di antaranya enam isolat berasal dari K1 dan sepuluh isolat berasal dari K2. Dari 10 isolat bakteri Gram negatif yang ditemukan pada sapi RB terdiri atas Escherichia coli (E. coli) (30,00%), Pseudomonas sp. (30,00%), Enterobacter sp. (20,00%), Klebsiella sp. (20,00%). Disimpulkan bahwa bakteri yang paling banyak menginfeksi uterus sapi RB adalah E. coli dan Pseudomonas sp. (Isolation and identification of gram negative bacteria in uterine Aceh cow with repeat breeding) ABSTRACT. The study determined the type of Gram negative bacteria of the Aceh cattle uterus which has been diagnosed with repeat breeding. The study was conducted on six Aceh cows consists of 3 normal fertile cows (K1) and 3 repeat breeding cows (K2, RB). The bacteria in uterine samples were collected using sterile swab, kept into nutrient broth (NB) for further isolation and identification of bacteria. The result of the study showed that the total of 16 isolates of bacteria was observed in all cows : 6 isolates from group K1 and 10 isolates from group K2. A total of 10 isolates from cattle with repeat breeding consist of Escherichia coli (E. coli) (30.00%), Pseudomonas sp (30.00%), Enterobacter sp (20.0%), and Klebsiella sp (20.0%). It can be concluded that the most bacteria that infect uterine cows with repeat breeding are E. coli and Pseudomonas sp.

The aim of this research was to investigate the effect of red watermelon (Citrullus vulgaris) extract to the value of erythrocytes, hemoglobin, and hematocrit of mice (Mus muscullus) exposed to cigarette smoke. This study followed direct complete randomized design by using 12 males’ mice which divided into 4 groups. The treatment group is divided by the negative control group which given 0,5 ml of aquadest, the positive control group which exposed to cigarette smoke and 0,5 ml of aquadest. The treatment group I was exposed to cigarette smoke and given red watermelon extract dose 22 mg/Bw mice. The treatment group II was exposed to cigarette smoke and given red with watermelon extract dose 44 mg/Bw mice. The exposure to cigarette smoke and the given of red watermelon extract were conducted for 30 days. The blood taking was performed on day 31 in the Plexus retroorbital.  Furthermore, the number of erythrocytes, hemoglobin and hematocrit were calculated. The data were analyzed using ANOVA completely randomized design with SPSS for Windows 16.0. The results of this study showed that the extract of red watermelon for 30 days showed a highly significant effect (P 0.01) to the number of erythrocytes, hemoglobin, and hematocrit of mice. It is concluded that free radicals contained in the cigarette can cause a hemoglobin desaturation, increased blood viscosity, oxidative stress and red watermelon extract can minimize the damage.

This study aims to determine the ability of red betel leaf (Piper crocatum) or Moringa leaf extracts to reduce the endometritis level in Aceh cattle. In this study, six Aceh cows aged 3-5 years, weighing 150-250 kg from the Experimental Animal Technical Implementation Unit of Faculty of Veterinary Medicine of Syiah Kuala University were used. The cows were divided into two treatment groups, namely cows with endometritis that were given red betel leaf extract (T1) and cows with endometritis that were given Moringa leaf extract (T2). Examination of the endometritis levels was carried out before and after treatment using the White Side Test (WST) method. The collection of estrus cervical mucus was needed for the WST examination, and heat induction was performed with prostaglandin F2 alpha (PGF2α) at a dose of 25 μg. Collection of cervical mucus was performed 8-12 hours after the initiation of heat. All cows with endometritis were given intrauterine extracts of red betel leaves or Moringa leaves at a concentration of 20% every 24 hours for a week at a solution volume of 20 ml. The data were then analyzed using a paired t test. The mean endometritis levels before and after treatment on K1 vs. K2 were 3.0 and 1.7 vs. 2.7 and 2.7, respectively (P<0.05). It was concluded that red betel leaf extract at a concentration of 20% was more effective in reducing the endometritis level of Aceh cows than Moringa leaf extract.

The purpose of this research was to determine the potency of methanolic extract of sernai stem (Wedelia bilflora) as analgesic to mice (Mus muculus) compared to ibuprofen. This research use split-plot method with 5 treatments and 5 replications. Group P0 as negative control was given aquadest, P1 as positive control was given ibuprofen, while P2, P3, and P4 were given the extract with dosage of 40, 50, and 60 mg/kg bw, respectively. The pain analysis of mice was conducted using hotplate method and the observation was carried out at 0 minute, 30 minutes, 60 minutes, 90 minutes, and 120 minutes. The data was analyzed using analysis of varians (Anova) followed by Duncan’s test. The results of this research showed  that P1, P2, P3 and P4 had significant difference (P0,05) from P0. P1 did not have significant  difference (P0,05) from P2 but it was different from P3 and P4 (P0,05). From this result we can conclude that methanolic extract of sernai stem was potential as analgesic, dosage of 40 mg/kg bw was equal to ibuprofen, while 50 mg/kg bw and 60 mg/kg bw showed better effect than ibuprofen.

This study aimed to determine the effect of the red watermelon extract can affect the number of leukocytes in mice exposed to cigarette smoke. This study was designed with a completely randomized design using a unidirectional pattern 20 male mice (Mus muscullus) were divided into 4 groups. K1 negative controls were given 0.5 ml of distilled water, K2 positive control by exposure to cigarette smoke and 0.5 ml of distilled water, K3 by exposure to cigarette smoke and red watermelon extract were given a dose of 22 mg / mouse and K4 by exposure to cigarette smoke and were given extracts of red watermelon a dose of 44 mg / mouse. Exposure to cigarette smoke and red watermelon extract conducted for 30 days, making blood on day 31. Blood sampling performed at Plexus Retroorbitalis. Furthermore, counting the number of leukocytes. Data were analyzed using ANOVA completely randomized design with SPSS for Windows 16.0. The results of this study showed that the extract of watermelon for 30 days showed their real influence (P 0.05) to the number of leukocytes in mice. It is concluded that free radicals contained in cigarette can cause a leukocytosis, an inflammatory, oxidative stress and red watermelon extract can minimize cell damage.

The experiment was conducted to compare estrous performance between and estradiol level kacang and Nubian goats estrous induction by prostaglandin F2 alpha (PGF2α). Eight female goats were divided into two groups, groups 1 (K1) consisted five Nubian goats and group 2 (K2) included three kacang goats with criterias as follows: age 1.5-3.0 years old, not pregnant, at least two months postpartum, and healthy clinically. All goats were estrous synchronized by double injection 7,5 mg PGF2α intramuscularly with 10 days interval. Goats that appeared estrus symptoms were mated naturally to a male goat. Determination of estrous intensity was performed using scoring method. Blood samples were taken at the first time the goats were mated (day 0). The measurement of estradiol concentration was done by enzyme linked immunosorbent assay (ELISA) method. Data of intensity, onset, duration, and estradiol level were analyzed using t test. The results showed that the rate of intensity, onset, duration, and estradiol level of estrous at KI vs KII were 2.08±0.52 vs 1.85±0.67, 56.00±34.11 vs 40.80±18.20 hours, and 24.00±26.15 vs 33.80±9.10 hours, and 103.51±42.49 vs 67.95±38.44 pg/ml (P>0,05). It can be concluded there was no difference of estrous performance and estradiol level between kacang and Nubian which estrous induction with PGF2α. The relationship between the intensity of estrus estradiol level in the Nubian goats was 0.995 while the kacang goats was 0.890.
