Abstract

Sumber air panas merupakan salah satu habitat alami dari bakteri termofilik. Bakteri termofilik adalah kelompok bakteri yang mampu tumbuh pada suhu lingkungan yang tinggi, berkisar antara 45°-90°C. Penelitian ini bertujuan untuk mengetahui jumlah dan karakterisasi morfologi isolat bakteri termofilik yang dapat diisolasi dari sumber air panas Pincara. Metode penelitian yang dilakukan adalah deskriptf eksploratif, dengan mengambil sampel pada sumber air panas Pincara. Isolasi dan karakterisasi morfologis dilakukan di Laboratorium Sel dan Jaringan Fakultas Sains Universitas Cokroaminoto Palopo. Isolat dikulturkan pada medium Luriah Bertani Agar (LBA) dan diinkubasi pada suhu ±50ºC selama 3x24 jam. Sebanyak 3 isolat murni bakteri termofilik ditemukan dengan karakteristik bervariasi. Semua isolat bakteri merupakan bakteri Gram positif dan berbentuk basil. Isolat P1 memiliki karakteristik morfologi koloni dengan pigmentasi putih krem, bentuk circular, tepi entire, dan elevasi convex. Isolat P2 memiliki karakteristik morfologi koloni dengan pigmentasi putih krem, bentuk circular, tepi entire, dan elevasi flat. Sedangkan isolat P3 memiliki karakterisasi morfologi koloni dengan pigmentasi putih krem, bentuk irreguler, tepi undulate, dan elevasi flat.

Abstract

Sea star is an invertebrate animal that is included in the phylum Echinoderms from the Asteroidea class. Radial symmetry is shaped and generally has five or more arms and does not have a frame that helps movement. This study aims to determine the diversity of sea star (Asteroidea) in Lamalaka Beach, Ile Boleng District, East Flores Regency.This research will be conducted in July-August 2019, the location of the study is on the Lamalaka coast, Ile Boleng District, East Flores Regency.The method used is a survey method, based on the presence of Asteroidea species that are considered to represent the area. The steps in data collection are field survey, observation, identifying species in each plot, observing and recording their marphological characteristics.Sampling uses the technique of determining the location of sampling using Area sampling. To identify based on Human and Deloach identification guidelines, 2010. Analysis of the data used in this research is quantitative descriptive and the composition of Asteroidea species can be stated based on visual observations calculating species density, relative density, and dominance index, diversity.Based on the results of the study, found 4 species of Asteroidea, namely Protoreaster nodulosus, Linckia laevigata, Echinaster luzonicus, Astropecten polyacanthus. The highest species density calculation results were found in P. nodulosus species with a value of 0.78 ind / m2. while the lowest species density was found in L.laevigata species with a value of 0.63 ind / m2. The highest relative density was found in P. nodulosus species with a value of 27.64%, and the lowest relative density found in L.laevigata species with a value of 22.35 %. The index of starfish species dominance in Lamalaka Beach, obtained a value of D <0.5, indicates that there are no species that dominate in Lamalaka Beach. The existence of starfish in Lamalaka Beach, Ile Boleng District, East Flores Regency needs to be preserved. One form of effort to preserve it is to conduct monitoring with routine monitoring to monitor the condition of the sea star population in these waters. Besides that, it is also necessary to increase the utilization of sea stars as one of the natural tourism objects and as an Ecoedutourism tourism object. Thus, the presence of starfish will be felt by the wider community so that awareness to maintain the existence of starfish will be increased.

Abstract

ABSTRACTResearch is a ethnobotany of medicinal plants in Barene Village, Central Malaka District, Malacca Regency which aims to find out what types of plants are utilized by the people of Barene Village, what plant organs are used in medicine, how to process these plants for traditional medicine and the benefits of medicinal plants. Sampling was conducted in Barene Village, Central Malaka District, Malacca District. This type of research is a descriptive study with a sampling technique approach conducted by purposive sampling. Data collection methods used are observation, interviews, and documentation. Data from the results of subsequent studies were analyzed descriptively qualitatively according to the purpose of the study which would later be presented in the form of tables, photographs or images. The results showed that in Barene Village there were 20 types of plants that were used by the community as traditional medicine. Plant organ parts used in medicine are leaves, leaf buds, roots, bark, rhizomes, leaves and bark. How to process these plants in traditional medicine that is boiled, chewed, eaten, pounded, and soaked. The people of Barene Village use the ingredients more often by boiling and then drinking. The part that is most used by the people of Barene Village as a treatment for the use of leaves. The benefits of traditional medicinal plants are efficacious in curing several types of diseases.Keywords: Ethnobotany, Medicinal Plants, Barene Village Community

Abstract

ABSTRACTMangrove plant is one of the coastal ecosystems that dominates the coastal area and has the potential to be developed in the prevention of various diseases both infections in aquaculture and as a natural treatment medium for humans, because the secondary metabolite compound contained can be efficacious as an anti-bacterial. The purpose of this study was to determine the effect of A. marina mangrove bark extract against the growth of E. coli and the optimum concentration of A. marina mangrove bark extract in inhibiting the growth of E. coli bacteria. The method used in this study is a laboratory experimental method with 4 treatments namely a concentration of 55 mg/mL, 60 mg/mL, 65 mg/mL, 70 mg/mL and 1 control without administration of extract with 3 replications. Observation result of inhibition zone diameters were statistically analyzed using a one-way analysis was performed using the SPSS program version 16.0. the results showed that the rough extract of A. marina mangrove bark affected the growth of E. coli bacteria. This can be seen from the concentrations used starting from 55 mg/mL, 60 mg/mL, 65 mg/mL and 70 mg/mL having average inhibition zones ranging from 26 mm, 27.33 mm, 27.66 mm and 28.66 mm. thus the higher the concentration of the extract used, the greatervthe inhibition formed.

Abstract

The purpose of this study was to determine the effect of role playing learning models assisted by digital comic learning media on student learning outcomes. The method used is quasi experiment. The research design used was posttest only control design. Data collection techniques using the Learning Outcomes Test. Data management and analysis using the polled variance t-test formula with SPSS version 16 statistical test. Based on the results of data analysis, it shows that there is a significant effect with tcount greater than ttable, 6.488> 1.674, it can be concluded that H1 is accepted and H0 is rejected, meaning there is a significant influence in the use of role playing learning models assisted by digital comic learning media towards student learning outcomes.
