Abstract

Commerson’s anchovy (Stolephorus commersonnii) is a small pelagic fish that live in a group and its existence is very abundant in Segara Anakan Cilacap. This anchovy is widely consumed by communities live around Segara Anakan. This leads to a high exploitation rate. Exploited populations generally have low genetic diversity. This study aims to evaluate genetic diversity of commerson’s anchovy population in Segara Anakan Cilacap inferred from PCR-RFLP of the cytochrome c oxidase 1 (CO1) gene. This study was conducted from January to April 2018 and used survey method by applying random sampling. As many as 30 samples of anchovy were taken. Genomic mtDNA was isolated using modified Chelex method. Partial sequences of the COI gene were amplified using a pair forward commercially available primer. The lengths of 650 base pair of the PCR products were digested with four restriction enzymes. The HindIII enzyme produces PCR-RFLP fragment with the size of 416 bp and 234 bp lengths, VspI produces 435 bp and 214 bp, CO1-TaqI produces 556 bp and 94 bp and RsaI produces 319 bp, 183 bp, and 148 bp fragments, respectively. The PCR-RFLP fragments were obtained from all samples but they produced uniform band pattern for all 30 anchovy individuals. These results indicated that the anchovy population in Segara Anakan Cilacap has monomorphic allele for all PCR-RFLP markers. Hence, it can be concluded that genetic homogenity was observed on anchovy population in Segara Anakan Cilacap as inferred from PCR-RFLP COI gene.

Abstract

Penelitian ini bertujuan untuk mengonstruksi perpustakaan metagenom tanah dari sekitar lokasi industri pengolahan minyak kelapa di Kabupaten Banyumas, Jawa Tengah, dalam upaya mendapatkan klon rekombinan dengan aktivitas lipase indigenuos. Penelitian dilakukan di Laboratorium Genetika, Fakultas Biologi, Universitas Jenderal Soedirman mulai bulan Mei hingga Desember 2006. Secara umum tahapan penelitian terdiri atas ekstraksi dan pemurnian DNA tanah, isolasi pUC19, pemotongan DNA tanah, pemotongan dan defosforilasi pUC19, ligasi fragmen-fragmen DNA tanah ke dalam pUC19 untuk menghasilkan molekul DNA rekombinan, dan transformasi sel inang E. coli JM109 menggunakan molekul DNA rekombinan yang diperoleh untuk mengonstruksi perpustakaan metagenom tanah. Pemotongan DNA tanah menghasilkan fragmen-fragmen yang sebagian besar berukuran lebih kurang 5 kb sehingga gen lipase dimungkinkan untuk dibawa di dalamnya. Transformasi sel inang E. coli JM109 memperlihatkan efisiensi 1.7 x 105 cfu/μg plasmid. Di antara koloni-koloni yang diperoleh, terdapat 102 koloni berwarna putih, yang menunjukkan keberadaan molekul DNA rekombinan. Koloni putih ini dapat digunakan sebagai materi untuk skrining klon rekombinan dengan aktivitas lipase.

PEMERIKSAAN BAKTERI LEPTOSPIRA PADA SAMPEL DARAH MANUSIA SUSPECT LEPTOSPIROSIS MENGGUNAKAN METODE PCR (POLYMERASE CHAIN REACTION) Abstract ABSTRACTLeptospirosis is a zoonotic disease, which is caused by leptospira. Leptospirosis cases often show no specificclinical symptoms and is difficult to diagnose without testing samples in the laboratory. Testing using PCR(Polymerase Chain Reaction) is considered more accurate than the other methods. Components required in theexamination Leptospira bacteria in human blood samples using PCR method is DNA template, DNA polymeraseenzyme, forward primer (PU1 and SU1) and reverse primer (Lep R1), nuclease free water, Mg 2 +, and dNTPs.Examination of Leptospira bacteria in human blood samples include sampling, DNA isolation, examination byPCR, and electrophoresis running.Key words: leptospirosis, Leptospira, PCR methods ABSTRAKLeptospirosis adalah penyakit zoonosis yang disebabkan oleh bakteri Leptospira. Kasus leptospirosis seringtidak menunjukkan gejala klinis yang spesifik dan sulit didiagnosis tanpa pengujian sampel di laboratorium.Pengujian dengan menggunakan metode PCR (Polymerase Chain Reaction) dinilai lebih akurat dibandingkandengan metode yang lain. Komponen-komponen yang dibutuhkan dalam pemeriksaan bakteri Leptospira padasampel darah manusia menggunakan metode PCR adalah DNA template, enzim polymerase, Primer PU 1 danPrimer SU 1, Primer Lep R1, air, Mg2+ , dan dNTP.

Abstract

Yoghurt merupakan produk pangan fungsional hasil fermentasi dari susu yang melibatkan peran bakteri asam laktat (BAL) Lactobacillus bulgaricus dan Streptococcus thermophillus. Menurut beberapa penelitian terdapat BAL yang memiliki ketahanan lebih baik dalam saluran pencernaan manusia, yaitu Bifidobacterium sp.. Selain itu, Bifidobacterium sp. memiliki manfaat diantaranya adalah meningkatkan fungsi pencernaan, menurunkan kolestrol, sebagai antioksidan dan anti inflamasi, mengurangi gejala alergi, serta dianggap sebagai salah satu bakteri probiotik yang penting dalam tubuh manusia. Tujuan dari penelitian adalah mengetahui pengaruh penambahan Bifidobacterium sp. Bb2E terhadap kualitas yoghurt dan mengetahui konsentrasi Bifidobacterium sp. Bb2E yang terbaik dari segi organoleptik. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 kali ulangan, sehingga terdapat 12 unit percobaan. Perlakuan yang diterapkan adalah perbandingan konsentrasi starter yoghurt yang berbeda dari BAL L. bulgaricus, S. thermophillus dan substitusi Bifidobacterium sp. Bb2E dengan perbandingan 2:2:0 (Y0), 2:2:1 (Y1), 2:2:2 (Y2), dan 2:2:3 (Y3). Variabel dalam penelitian ini, variabel bebas, yaitu konsentrasi Bifidobacterium sp. Bb2E dan variabel terikat, yaitu kualitas yoghurt. Parameter utama adalah kadar asam laktat. Parameter pendukung, yaitu total BAL pada yoghurt, nilai pH, dan sifat organoleptik pada yoghurt. Data diolah dengan Analysis of Variance (ANOVA) dengan taraf kesalahan 5%. Penambahan Bifidobacterium sp. Bb2E tidak memberi pengaruh nyata terhadap kualitas yoghurt dari segi kadar asam laktat, pH, dan total BAL dan yoghurt dengan starter Lactobacillus bulgaricus : Streptococcus thermophillus : Bifidobacterium sp. Bb2E dengan perbandingan konsentrasi 2:2:3 merupakan yoghurt yang disukai konsumen dengan nilai rata-rata tertinggi pada uji organoleptik.

Abstract

The purpose of this study is to asses motility and viability of domestic duck (Anas platyrhyncos) spermatozoa after 6 day storing in preservation medium of different egg yolk cryoprotectant concentration in three different medium Tris, PBS or Ringer lactate. In this experiment, we applied 3 combination of factors as treatments : extender (Tris, PBS or Ringer lactate), egg yolk (EY) concentration (0, 5, 10, 15 or 25%) and storage time (0,1,2,3,4,5,6 days). Spermatozoa was obtained by massage technique, ejaculate then were swup up in the extender, the swup-up sperm then were incubated in preservation medium as each treatments subjected to motility and viability assesment before and after storage at refrigerator temperature (50C). The results showed that sperm motility and viability were highly significantly different (P<0.01) among 107 treatments. Extender factor as well as storage duration time were highly significantly different (P<0.01) affected the motility and viability of the treated sperm. EY concentration was significantly (P<0.05) affected viability, however there were no factor (P>0.05) affected motility of the sperm. The best treatment resulted in promising quality having the highest motility of 46,67 ± 32,15 5 motile was from the treatment of 10% EY in PBS stored for 4 days. The best viability result was from the tretament of 25% EY in PBS after 4 days storage resulted in 50,00 ± 36,05 % of viabie sperm. In conclusion this protocol could be applied for artificial insemination trial.

Abstract

The economic value of ducks has increased one Day Old Duck in large quantities and short time, effects on artificial insemination technologies improvement. Spermatozoa used for artificial insemination, could be derived from sperm preservation biotechnology, by means to maintain or extend their viability and motility of those spermatozoa. Extenders and cryoprotectant are needed for maintaining sperm motility and viability during storage or preservation. This study aims to assess motility and viability of local ducks spermatozoa after six days srotrage in 3 different extenders (Ringer's lactate, Tris or PBS) in combination with 5 different concentrations (0, 2, 4, 6, and 8%) of cryoprotectant glycerol. Results showed that sperm motility and viability was very highly significant (P<0.01) different among treatments, extender factor as well as duration storage time also very highly significantly (P<0.01) affected motility and viability of treated sperm. However, glycerol concentration factor was not significant (P>0.05) affected motility and viability of the sperm. The best treatment, resulted in the highest percentage motility and viability of sperm with progressivity score >1, was the 8% glycerol in PBS storage for up to 2 days (75.00 ± 21.79% and 71.67±14.43%). This protocol could be applied in artificial insemination trial.
