Uji Antagonis Jamur Tempe (Rhizopus Sp) terhadap Bakteri Patogen Enterik
Get PDFIndonesian tempeh is a food product made from soybeans fermented by Rhizopus oligosporus. The role of R.oligosporus as the primary fungi in soybean is very important, that changing the composition of the substrate soybeans into food that is more nutritious and contains many enzymes and bioactive compounds, including antibacterial compounds. This study was aimed at testing the antibacterial activity of Rhizopus sp fungus isolated from commercial tempeh against several enteric pathogen bacteria Escherichia coli ATCC 25922, Salmonella typhimurium ATCC 14028 and Shigella flexneri ATCC 12022. The tests were conducted by the antagonism test agar diffusion method, by putting pieces of SDA that has grown Rhizopus sp on agar Muller Hinton which test bacteria was inoculated. The incubation period was 24 hours at 37 ° C. The results showed that Rhizopus sp has antagonistic to the bacteria, which produce inhibitory zone of 28 mm against the E.coli ATCC 25922, 26 mm against S.typhimurium ATCC 14028 and 39.5 mm against Shigella flexneri ATCC 12022. Based on these results it can be concluded that the Rhizopus sp isolated from tempeh is antagonistic against enteric pathogenic bacteria. The results of this study reinforce the benefits of tempeh as a functional food

PENGARUH PEMBERIAN EKSTRAK KULIT PISANG KEPOK KUNING (Musa balbisiana) TERHADAP ASUPAN MAKAN DAN BERAT BADAN TIKUS WISTAR (Rattus norvegicus) JANTAN
Get PDFA positive energy imbalance results in overweight and obesity. Overweight and obesity are the major risk factors for many diseases, including diabetes, cardiovascular diseases, and mental health. Animal studies suggested that serotonin involves in food intake control. The Banana peel is a potential natural source of serotonin precursor; furthermore, it may influence food intake. This study aimed to determine the effect of banana peel extract on food intake and body weight gain in male Wistar rats. Twenty-four male Wistar rats (8-10 weeks old), were divided into four groups for feeding treatment. All four group were; the control group (C), the banana peel extract dosage of 4 g/kg BW group (T1), the banana peel extract dosage of 8 g/kg BW (T2), and the banana peel extract dosage of 16 g/kg BW (T3). The food intakes were measured daily, while rats body weights were recorded at the beginning and the end of the three days experimental periods. The study found the rats in the T1 group (8.80 ± 2.63) showed no significant difference in food intake compared to C group (10.68 ± 1.89), T2 group (6.65 ± 3.12), and T3 group (5.42 ± 1.59). Rats in the T2 group (p = 0.038) and T3 group (p = 0.005) showed lower food intake significantly compared to control group. After three days of treatment, the T3 group showed a significant decrease in body weight compared to control group (p = 0.008). This study concluded, the administration of banana peel extract dosage of 8 g/kg BW and 16 g/kg BW suppressed food intake, while the dosage of 16 g/kg BW reduced the body weight in male Wistar rats
STUDI PERILAKU GAJAH SUMATERA, Elephas maximus sumatranus UNTUK MENDUKUNG KEGIATAN EKOWISATA DI PUSAT KONSERVASI GAJAH TAMAN NASIONAL WAY KAMBAS
No full textStudies of Sumatran elephant behavior that include the typical behavior of each elephant individual is significant to support ecotourism activities. Information on the elephant behavior obtained by scientific observation can be presented to tourists to provide exciting insights and knowledge during their visit to the Way Kambas Elephant Conservation Center (PKG). This study aimed to determine elephant behavior based on gender, age, the origin of capture, the training time, and also to examine the elephant behavior in supporting ecotourism activities in PKG Way Kambas. The results indicated that the behavior of Sumatran elephants could be determined by sex, age, the origin of capture, and the training period. The male elephant has a more aggressive response than female elephants. The mahout efficiently instructed the adult elephants than the baby, toddlers, and youngsters elephants. The elephant's behavior born in PKG compared to those from capture in the wild were different. Those born in PKG were easier to tame than elephants from outside PKG. Duration of training was also influential to elephants behavior, the longer they were trained, the tamer the elephants. The training was prepared to elephants so that the elephants can be safely presented and familiar to tourist to raise fund for PKG primarily to support the elephant caring and handling
LEUKOCYTE DIFFERENTIAL OF ANGUILLID EEL, Anguilla bicolor McClelland, EXPOSED TO VARIED SALINITIES
Get PDFThe anguillid eel is a catadromous eel capable of inhabiting freshwater growth habitat and seawater spawning habitat throughout their life cycle. At the juvenile to mature stage, they inhabit freshwater then migrate to marine water to spawn. Changes in salinity, which is one of the stressful environmental factors for the eel, affect their physiological condition by increasing the leukocytes number. This increase is an adaptation method to improve their immune system as a response to salinity change. This study intended to evaluate the leukocyte differential of anguillid eel (Anguilla bicolor McClelland) exposed to various salinities. This research applied a Completely Randomized Design. The treatment was three levels of saline media including 4 ppt, 15 ppt, and 30 ppt with five replicates. The independent variable was the different salinity, and the dependent variable was the leukocyte differential. The parameters measured consisted of the different percentage of neutrophils, lymphocytes, monocytes, and eosinophils in which the measurements administered after two months of the eel exposure. We analyzed the data with ANOVA at the confidence level of 95%. The results showed that exposure of salinity significantly affected the percentage of leukocyte differential (P < 0.05). The increase in salinity decreased the neutrophils and monocytes, but increased the lymphocytes, and showed no effect on eosinophils

Get PDFRumput laut memiliki beberapa aplikasi ekonomi dalam berbagai jenis industri, salah satunya untuk industri kosmetik. Salah satu kosmetik yang banyak digunakan yaitu krim tabir surya. Efektivitas dari krim tabir surya biasanya dinyatakan dengan nilai SPF (sun protection factor). Tujuan dari penelitian ini adalah untuk mengetahui kandungan senyawa aktif dan nilai SPF pada ekstrak rumput laut Turbinaria conoides dan Eucheuma cottonii yang dapat digunakan sebagai bahan aktif pada sediaan krim tabir surya. Hasil pengujian menunjukkan rumput laut Turbinaria conoides mengandung golongan senyawa fenol hidrokuinon, flavonoid, triterpenoid, steroid, dan saponin. Rumput laut Eucheuma cottonii hanya ditemukan senyawa alkaloid. Nilai SPF tertinggi pada rumput laut Turbinaria conoides terdapat pada ekstrak metanol (SPF 16.7), sedangkan untuk rumput laut Eucheuma cottonii terdapat pada ekstrak etil asetat (SPF 8.8). Hasil tersebut memperlihatkan bahwa ekstrak dari rumput laut Turbinaria conoides dan Eucheuma cottonii memiliki potensi yang baik jika digunakan sebagai bahan aktif pada sediaan krim tabir surya.

Tujuh individu yang dipelajari merupakan spesies semiendemik Gunung Slamet dan endemik Jawa, yaitu N. adrianii dan N. gymnampora. Metode yang digunakan adalah survei dengan teknik pengambilan sampel secara acak. DNA genomik sampel diekstraksi untuk kemudian digunakan sebagai templat dalam amplifikasi marka RAPD menggunakan teknik PCR dengan 10 primer acak, yaitu ES10G23, ES10A26, ES10C24, ES10G33, OPA-2, OPA-9, OPA-13, OPB-3, OPB-5, dan OPB-7. Hasil penelitian menunjukkan bahwa ke-10 primer tersebut menghasilkan 43 (67,2%) pita polimorfik dan 21 (32,8%) pita monomorfik dengan ukuran berkisar dari 130 hingga 1.500 bp. OPA-2 and OPB-3 menghasilkan polimorfisme tertinggi, sedangkan ES10G23 dan OPA-13 menghasilkan pita monomorfik terbanyak. Dendogram yang dikonstruksi menggunakan UPGMA dalam MEGA 6.06 memperlihatkan bahwa dua klaster terbentuk pada jarak genetik 18%. Kedua klaster tersebut cenderung dipisahkan oleh lokasi geografi
