KUALITAS AIR WADUK PENJALIN BERDASARKAN STRUKTUR KOMUNITAS MAKROBENTHOS
Get PDFMacrobenthos is one of the biotic water constituent and can be used as bioindicator in determining water quality conditions. Water quality can be seen in terms of community structure of macrobenthos. The present study aimed to determine the physical and chemical water qualities in Penjalin Reservoir and to know the community structure of macrobenthos contained in the waters of Penjalin Reservoir. Community structure includes Density (organism/m2), Relative Density, Dominance Index (C) and Diversity Index (H ') as well as to determine the relationship between the water quality (physical and chemical) and the macrobenthos density. The physical and chemical qualities of Penjalin Reservoir water was good based on class III water quality standard according to PP No. 82 Ttahun 2001. Based on observation, 11 macrobenthos were obtained. Diversity Index (H') based on the criteria of Lee et al. (1978) showed moderate values (2.07 to 1.66) suggesting a low contamination level. The relationship of macrobenthos density and its chemical and physical quality of water pH, temperature, light penetration, depth, DO, BOD was weak, but had strong relationship with TSS. The results showed a linear regression equation Y = 898.76 X - 236.946 (Y = density and X = TSS) which could be interpreted that the more value of macrobenthos density the higher value of TSS contained in the water
VARIASI SEKUENS DNA YANG DIAMPLIFIKASI MENGGUNAKAN PRIMER atpB-rbcL PADA BEBERAPA KULTIVAR KACANG TANAH
Get PDFPeanut is one of food crops commonly consumed in Indonesia. This species comprises several cultivars such as Kancil, Bison, Jerapah, Talam, and Tuban, each of which has its individual advantages and disadvantages. The vast variation among peanut cultivars leads to the need of study on genetic diversity and relationship among them using particular molecular marker. This study aims to see whether variation on DNA sequences among some peanut cultivars amplified with atpB-rbcL primers exists or not and to know the relationship among the cultivars based on the amplicon sequences. The method involves some sequential steps, i.e. genomic DNA isolation using CTAB protocol, amplification of DNA sequence using atpB-rbcL primers and sequencing of the amplification products. Data on sequences were edited manually using Bioedit version 7.0.4.1. Sequence alignment was performed using ClustalW, which is also implemented in Bioedit version 7.0.4.1. Arlequin 2.0 was used to calculate nucleotide diversity p. Phylogenetic analysis was performed using Maximum Parsimony in MEGA 5.0. The results showed that considerably high variation in DNA sequences of some peanut cultivars amplified with atpB-rbcL primers are observed. On the other hands, very close genetic relationship among cultivars is found
GAMBARAN HEMATOLOGI MENCIT (Mus musculus) MODEL TOKSISITAS SUBKRONIS
Get PDFGarlic commonly is consumed as medicine to prevent or heal illness or to maintain someone's health. Many societies prefer garlic (Allium sativum) among other herbal remedies for cholesterol treatment. It consists of several types, and one of them is single bulb garlic used to treat hypertension. There has been, however, no published research reporting the toxicological properties of single bulb garlic. The purpose of this study was to determine subchronic toxic effects of single bulb garlic administered to mice using hematological parameters. The experiment parameters were hemoglobin and hematocrit levels, the number of erythrocytes and leukocytes. Male mice (Mus musculus) strain Balb-C were treated with single bulb garlic extract for 28 days with dosage levels of 0% (N ), 0.25% (P1 ), 0.5% (P2 ), 1% (P3 ), and 2% (P4 ). Single bulb garlic showed no effect on hemoglobin and hematocrit levels but increased the number of erythrocyte and leucocyte. We concluded that single bulb garlic did not cause subchronic toxic effects

In Indonesia, watermelon has diversity in its cultivar as can be seen from the stem, leaf, flower, and fruit morphology. This research is aimed to find out the diversity and the similarity relationship of watermelon cultivar in Nusawungu, Cilacap. A survey method was used in this research by taking the samples with a random sampling technique (purposive sampling). This research parameter consisted of stem, leaf, flower, and fruit morphology of each watermelon cultivar. Data of watermelon cultivar morphology were analyzed descriptively and then analyzed based on the similarity relationship with UPGMA method (Unweighted Pair Group Method with Arithmetic Mean) using the MEGA 5.05 software. The result of this research showed that there were five watermelon cultivars namely C. lanatus ‘Farmers Giant’, C. lanatus ‘Nina’, C. lanatus ‘Black Orange’, C. lanatus ‘Torpedo’, and C. lanatus ‘Bintang’. There were two groups of watermelons based on phenetic analysis namely group I consisting of C. lanatus ‘Torpedo’, C. lanatus ‘Black Orange’, and C. lanatus ‘Nina’ cultivars, group II consisting of C. lanatus ‘Bintang’ and C. lanatus ‘Farmers Giant’. The closest similarity was between C. lanatus ‘Farmers Giant’ and C. lanatus ‘Bintang’ cultivars with the dissimilarity index of 0,516. While the most distantly related was between C. lanatus ‘Nina’ and C. lanatus ‘Farmers Giant’ cultivars with the dissimilarity index of 2,338
RAPD Profile Of Winged-Bean [Psophocarpus tetragonolobus (L.)DC] Mutated Using Ethyl-Methane Sulphonate
Get PDFGenetic diversity of winged-bean [Psophocarpus tetragonolobus (L.) DC] can be produced by induced mutation with EMS (ethyl-methane sulphonate). To identify the genetic diversity after EMS application on winged-bean, molecular analysis using RAPD (Randomly Amplified Polymorphic DNA) technique was carried out. This study aims to identify RAPD profile of winged-bean after EMS application. Winged-bean seeds of both long and short pod types were soaked in wet paper towels for 6 hours followed by soaking in EMS of 0.3% and 0.5% for 4 hours. Winged-bean seeds of both pod types without EMS served as control. Ten of the 30 primers operon technologies USA and 2 primers bangalore genei showed sufficiently clear bands (OPA 1, OPA 3, OPA 10, OPA 15, OPA 19, OPB 1, OPB 6, OPB 7, ES10C27, and ES10C28). All the ten primers produced polymorphic fragments with a total number of 320 and size ranging from 100 bp to 2,000 bp. As many as 66 loci were observed. The polymorphism values obtained ranged from 16.67% to 46.97%. This low polymorphism values indicate that EMS concentrations applied have not resulted in sufficiently high genetic variation. At the same time, the genetic distance observed were only 0.11 to 0.41
Ekspresi Relatif mRNA BRLF1 Epstein-Barr Virus dari Biopsi Jaringan Tumor dalam Blok Parafin sebagai Petanda Biologi Patogenesis Karsinoma Nasofaring
Get PDFKarsinoma nasofaring (KNF) merupakan tumor ganas pada sel epitel nasofaring dan merupakan penyakit multifaktor yang bersifat endemik. Tipe KNF tidak berdiferensiasi (KNF WHO-3) telah terbukti konsisten dengan infeksi EBV. Gen litik BRLF1 berperan sebagai mediator transisi dari fase laten menjadi litik. Pengukuran aktivitas mRNA EBV di lokasi tumor primer perlu dilakukan karena lebih mencerminkan patogenesis KNF yang sesungguhnya dari pada diagnosis serologi dan pengukuran DNA EBV di sirkulasi darah. Penelitian ini bertujuan untuk mengetahui nilai ekspresi relatif mRNA BRLF1 Epstein-Barr Virus pada beberapa tingkat stadium tumor penderita KNF sebagai petanda biologi potensial dalam patogenesis KNF. Metode penelitian yang digunakan adalah metode deskriptif yang berbentuk studi seran lintang. Sampel penelitian ini adalah biopsi jaringan tumor dalam blok parafin penderita KNF sebanyak 24 sampel. Sampel tersebut telah didiagnosis pasti sebagai KNF WHO-3 dari hasil pemeriksaan Patologi Anatomi pada Poli Patologi Anatomi, RSUD Prof. Dr. Margono Soekarjo, Purwokerto serta memenuhi kriteria inklusi sampel. Analisis statistik dilakukan untuk membandingkan ekspresi relatif mRNA BRLF1 stadium yang berbeda. Nilai ekspresi relatif mRNA BRLF1 EBV pada 24 sampel KNF berkisar 99,04415959-1097,496026. Hasil analisis statistik menunjukkan nilai ekspresi relatif mRNA BRLF1 EBV pada stadium awal (n = 5; 544,72420 + 142,614733) lebih tinggi 1,8 kali dibandingkan dengan stadium lanjut (n = 17; 395,68612 + 293,172201), namun peningkatan ekspresi relatif mRNA BRLF1 EBV tidak bermakna secara statistik karena didapatkan nilai p=0,130 (p>0,05). Oleh karena itu, ekspresi relatif mRNA BRLF1 EBV dari biopsi jaringan tumor dalam blok parafin tidak berpotensi sebagai petanda biologi molekul patogenesis KNF, khususnya progresivitas tumor pada stadium lanjut KNF
