Goat is one of the most important germplasm in supporting the economy of rural communities. Benggala is a local breed of goat originating from Flores Island, East Nusa Tenggara province and has distinctive characteristics. The RAPD technique has several advantages and has been widely used in studies of the genetic diversity of goats. A total of 50 blood samples of Benggala goats were taken from four sub-districts in West Manggarai Regency. This study was conducted to estimate genetic variations of Benggala goats using OPA-6 and OPA-16 primers. The OPA-6 primer consisted of 0-11 bands, while the OPA-16 primer consisted of 0-7 bands. The total bands produced on the OPA-6 primer from all samples was 456, whilst OPA-16 primer was 314. The lowest genetic similarity between individuals of Benggala goats was 44% from the sample K46. Based on the sample population, the average genetic similarity level was 72%. These results show that the genetic diversity of Benggala goats is low.Keywords: Benggala  goat, genetic similarity,genetic variation, RAPD, West Manggarai ABSTRAKIndonesia memiliki beberapa jenis kambing lokal yang memiliki periode adaptasi yang panjang dengan kondisi alam di Indonesia.

There is an increasing demand for Atlantic potatoes as the raw material for processed potato products. The demand, which has not been met by the increased production, has been the cause of the ongoing potato import activities in Indonesia. The limitation of producing quality Atlantic potato seeds economically is one of the obstacles to increasing the production of Atlantic potatoes in Indonesia. The aim of this research was to study the effect of various table sugar concentrations as the carbon source and the type of the culture containers used for Atlantic potato shoot multiplication in vitro.

The fermented fish feed, however, had poor floatability in aerated water, probably due to structural damage during the size reduction process of the feed. Thus, this study used alternative size-reducing methods, namely slicing and moulding, to improve the floatability of the fermented feed. Other physical characteristics were also measured and compared to those of commercial sinking and floating fish feeds. Results showed that both the moulded and the sliced fermented-feeds had lower density as well as higher water stability, absorption capacity, floatability, and durability compared to those of the commercial sinking feed used as the fermentation substrate.

Dari 30 isolat, 56,6% isolat menunjukkan adanya aktivitas antibakteri dan 36,6% dari isolat berpotensi sebagai pelarut fosfat, yang termasuk ke dalam marga Streptomyces, Actinomadura, dan Kitasatospora.Kata Kunci: 16S rRNA, Aktinomisetes, sedimen air tawar, antibakteri, pelarut fosfat","PeriodicalId":231498,"journal":{"name":"Jurnal Bioteknologi & Biosains Indonesia (JBBI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130271314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this research was to determine the effect of humic acid on the spleen of mice infected with Escherichia coli. The study used a completely randomized design with six treatments and five replicates. The treatments were normal control, negative control, positive control of isoprinosine, humic acid dose of 62.5; 125; and 250 mg/kg body weight (BW). The results showed that E. coli infection caused diarrhea symptoms and significant weight loss. There were significant differences (P<0.05) on hematocrit value and a total leukocyte count of humic acid, in which isoprinosine treatment was higher than those of negative control and normal control. There was no significant difference in the spleen weight of the mice subjected to the different treatments, but through histologic observations a significant difference (P<0.05) was found in the histologic size of the spleen. Humic acid treatment of 250 and 125 mg/kg BW resulted in the widest white pulp (495.8 ± 58.2 µm) and the highest leukocytes count (6725 ± 1018 cell/mL), respectively. On the red pulp serving as negative control numerous clusters of lymphocyte cells were found.Keywords: Escherichia coli, humic acid, peat soil, spleen, white pulp ABSTRAKSenyawa asam humat mempunyai potensi imunostimulan. Penelitian ini bertujuan mengetahui pengaruh pemberian asam humat terhadap organ limpa mencit yang diinfeksi bakteri Escherichia coli. Penelitian ini menggunakan rancangan acak lengkap dengan enam perlakuan dan lima ulangan. Perlakuan tersebut yakni kontrol normal, kontrol negatif, kontrol positif isoprinosin, asam humat dosis 62,5; 125; dan 250 mg/kg berat badan (BB). Hasil penelitian menunjukkan bahwa infeksi bakteri E. coli pada mencit menyebabkan mencit mengalami gejala diare dan penurunan berat badan yang signifikan. Perbedaan signifikan (P<0,05) pada nilai hematokrit dan jumlah leukosit total perlakuan asam humat dan isoprinosin lebih tinggi dibandingkan kontrol negatif dan kontrol normal. Tidak terdapat perbedaan nyata (P>0,05) pada berat limpa mencit antar perlakuan, melalui pengamatan histologi ditemukan perbedaan ukuran histologi limpa mencit. Perlakuan asam humat 250 mg/kg BB mempunyai ukuran pulpa putih (495,8 ± 58,2µm) dan perlakuan asam humat 125 mg/kg BB mempunyai nilai leukosit tertinggi (6725 ± 1018 sel/mL). Pada pulpa merah perlakuan kontrol negatif ditemukan banyak sel limfosit yang menggerombol.Kata Kunci: asam humat, Escherichia coli, limpa, pulpa putih, tanah gambut","PeriodicalId":231498,"journal":{"name":"Jurnal Bioteknologi & Biosains Indonesia (JBBI)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121836175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
