Identification of Actinomycetes in Freshwater Sediments from Mamasa, West Sulawesi and Their Antibacterial and Phosphate Solubilizing ActivitiesABSTRACTA large number of actinomycetes that have been isolated and screened were obtained from soil and marine samples. Consequently, the possibility of isolating novel Actinomycetes and secondary metabolites compounds strains from soil and marine samples have limited. Exploration of actinomycetes from freshwater sediment is rare. In this study, 30 isolates of Actinomycetes from freshwater sediments in Mamasa District, West Sulawesi were isolated, identified, and screened for their antibacterial and phosphate solubilizing activity. Actinomycetes were isolated by serial dilution method and were identified based on morphological and 16S rRNA gene sequence. Antibiotic activity was screened using the agar plug diffusion method, while soluble phosphate ability was observed by clear zone ratio in PKA medium. Most of the isolates belong to the genus Streptomyces (80%). Out of 30 isolates, 56.6% showed antibacterial activity and 36.6% had potential as solubilizing phosphate which belong to genus Streptomyces, Actinomadura, and Kitasatospora.Keywords: 16S rRNA, Actinomycetes, antibacterial, freshwater sediment, phosphate solubilizing ABSTRAKSebagian besar aktinomisetes yang telah diisolasi dan dilakukan penapisan metabolit sekundernya berasal dari sampel tanah dan laut.

Mosses growing on the surface of the Borobudur Temple will affect the aesthetic value of the temple. Interaction between moss and actinomycetes may trigger the growth of moss that can cause an increase in biodeterioration of stone. The purpose of this study was to isolate and identify the actinomycetes associated with moss on the surface of decayed stone of Borobudur Temple as well to assess their ability for phosphate solubilizing. Actinomycetes were isolated using serial dilution method and were identified based on 16S rRNA gene sequences. A total of 37 actinomycetes were isolated from three sampling sites. The isolates found belong to five genera (Gordonia, Microbacterium, Micromonospora, Nocardia, and Streptomyces) and distributed among four families (Microbacteriaceae, Micromonosporaceae, Nocardiaceae, and Streptomycetaceae). Isolates of actinomycetes composed of 19 Streptomyces Group and 18 Rare Actinomycetes Group. Nineteen isolates (51.35%) were identified as genus Streptomyces. Seventeen isolates (45.94%) showed abilities to release soluble phosphate and most of the isolates belong to the genus Streptomyces. The isolates have been collected will be deposited to Indonesian Culture Collection (InaCC) to enrich the collection of actinomycetes from ancient stone in Indonesia and will be used as a source of reference material research, taxonomic, or as source for further study.

Personal branding is the process of branding people and their work, and its motivation is different from awareness management and impression management. Providing benefits and brand equity associated with a particular individual is simply planned. Branding efforts usually require extensive financial support to make progress in order to raise brand awareness and soon afterwards to increase brand credibility. With its ideological and innovative structure, online networking gives the general public the opportunity to develop as a brand in a reasonably crude and productive way. Online personal branding refers to an approach that conveys the superior qualities of an individual in the online phase, helping to achieve professional goals with social aspirations, with the ultimate goal of separating oneself from others. increase. Various studies have focused on the importance of a solid personal brand, but generally overlooked how to create it in a virtual world, especially for an educator in the current era of digital technology. The purpose of this paper is to explore the different typefaces of different committees and explore the importance of building a personal brand for everyone.

The patient is an essential stakeholder within the medical healthcare system and an important stakeholder of the medical education program. The patients should be able to assess the performance of junior doctors in general practitioner residency to ensure their competency. Some instruments of patient assessment are available, but they do not adapt to local needs and context. This study aims to validate newly developed evaluation instruments from the patient’s perspective against the performance of a junior doctor in a teaching hospital. Fifty patients from outpatient clinics of internal medicine of two teaching hospital Faculty of Medicine Universitas Islam Bandung were selected to fill out the questionnaire in September–October 2018. The tool consists of 20 items and used a 4-point Likert scale of strongly disagree, disagree, agree, and strongly agree. The SPSS version 21 have used to extract the data as the principal axis factoring of analysis. Oblimin rotation method was applied with Kaiser normalization to simplify and describe the data structure. The detailed analysis identified five factors based on the initial eigenvalue >1. Patient perception instruments of junior doctor performance (PIJDP) showed that five constructs extracted explained 81.27% of the variance of them. Constructs were namely: humanism, responsibility-accountability, communication-empathy, altruism, and pleasant manner. Construct validity achieved after the PIJDP run fifteen times, and consistency internal with Cronbach’s alpha was 0.95. In conclusions, the PIJDP could be used to assess the performance of junior doctors and could make a novel contribution to the development of medical education.
