    • Authors: Muhamad Azmi Dwi Susanto, Okta Fina Arianti
      First page: 110
      Abstract: Sabo Dam Complang is a dam area that is minimally polluted and disturbed so that it has the potential as a natural habitat for various types of dragonflies. Diversity and abundance of dragonflies in a location is one component of biodiversity that plays an important role as a predator to maintain the balance of the food chain in natural ecosystems and as a bioindicator of water quality. This study aims to identify and analyze the diversity and abundance of dragonflies species at Sabo Dam Complang. Samples were taken using the VES (Visual Ecounter Survey) method and 2 transect methods, namely line transects and belt transects. The data that has been obtained were analyzed using the Shannon-Wienner species diversity index (H') and the relative abundance of species (KR). The results of this study show the diversity index value of 2.59 which is included in the relatively medium category. There were 20 species of dragonflies that belonged to 6 families.

      Abstract: Aspartame is one of the most widely used artificial sweeteners in food and beverages. In the body, aspartame will undergo metabolism into methanol which will be oxidized to formaldehyde. Formaldehyde will increase the production of ROS. The purpose of this study was to determine the effect of Catharanthus roseus leaves extract on kidney histology of mice aspartame-induced. Mice were divided into 4 groups, namely the negative control group (K-) without treatment, the positive control (K+) given aspartame 0.02 mg/day, the dose group 1 (D1) was given aspartame 0.02 mg/day and continued with the C. roseus leaves extract at a dose of 0.42 mg/kg, and group 2 (D2) were given aspartame 0.02 mg/day followed by C. roseus leaf extract at a dose of 0.84 mg/kg bw.  Aspartame was administered by IP for 14 days and C. roseus  leaves extract was administered by gavage for 12 days. The data obtained were analyzed by One Way Anova and DMRT test with a significance level of 0.05. The results showed that the induction of aspartame at a dose of 0.02 mg/day in mice increased the average number of proximal tubular necrosis cells. Catharanthus roseus leaves extract administration at 0.42 mg/kg bw and 0.84 mg/kg bw for 12 days can reduce the number of proximal tubular necrosis cells in aspartame-induced mice. Thus it can be concluded that the administration of C. roseus  leaves extract can reduce the proximal kidney tubules necrosis but has not been able to reach normal conditions yet.

  • Identification of Bacterial Symbiont Sponge with Antibacterial Activity
           against Multi Drug Resistant Organism (MDRO) Bacteria from Sea Waters in
           Sibolga, North Sumatra Indonesia

    • Authors: Endang Sulistyarini Gultom, Hasruddin Hasruddin, Aida Fitriani Sitompul, Albert D Situmorang, Eko Prasetya
      First page: 169
      Abstract: Irrational use of antibiotics for the treatment of infections in diseases caused by pathogenic bacteria can cause resistance. One way to overcome this resistance is to explore active compounds that have the potential as antibacteria of natural origin, namely sponge symbiont bacteria. This research method is experimental with descriptive data analysis. The purpose of this study was to isolate and identify sponge symbiont bacteria that have antibacterial potential against Multi Drug Resistance Organisms (MDRO) with the 16S rRNA gene marker. Based on the results of the study, 2 sponges were obtained, namely Clathrina sp and Agelas sp, each having 11 and 7 isolates of symbiont bacteria, respectively. Based on the results of the antibacterial activity test, out of 18 isolates of symbiont bacteria, only 4 had antibacterial potential against MDRO (Klebsiella pneumonia ESBL, Pseudomonas aeruginosa ESBL, or Stapyhlococcus lugdunensis MRSA) with inhibition zones of 9.3 mm, 8.3 mm, and 8.1 mm, respectively. The results of bacterial identification using the 16S rRNA gene sequence, isolates S1I3, S1I9, and A1I3 belong to the Bacillus cereus and Bacillus paramycoides types. This research is expected to provide important information about sponge symbiont bacteria that have antibacterial potential against MDRO.

      Abstract: Colchicine is often used in plant breeding to induce mutations to produce polyploid plants that have superior properties. Polyploid plants are plants that have more than one set of chromosomes in their somatic cells. Cytologically, polyploid plants have a larger variations in shape, the number of chromosomes, and cell size. The use of colchicine compounds in Kepok Abu Banana expected to produce the polyploid of  Kepok Abu Banana. The purpose of this study was to determine the emergence of mitotic abnormalities, changes in the number of chromosomes, the mitotic index, and the number and length of plantlet roots of Kepok Abu banana due to 0.1% of colchicine's application on tissue culture media. This research was conducted at the Botanical Laboratory of the Biology Department, Faculty of  Mathematics and Natural Sciences, University of Lampung. This study compared cytology with the Squash method between root tip cells of Kepok Abu banana's plantlets after 0.1% of colchicine addition with control. Data were analyzed descriptively and displayed in tables and bar charts. The results showed that 0.1% of colchicine caused mitotic abnormalities and increased the number of chromosomes. The control group resulted 2n = 3x, and the group with 0.1% of colchicine's treatment is 2n = 3x + 4. The mitotic index decreased, and the average number of roots was less, but the size was longer than the control. It can be concluded that 0.1% of colchicine can induce polyploid cells in Kepok Abu Banana plantlets.
