    Tea is commonly consumed in Nigeria. Caffeine, a major constituent in tea, has some beneficial pharmacological properties, but can negatively affect human health if consumed excessively. The objective of the study was to evaluate some physicochemical properties and caffeine content of teas marketed in FCT, Abuja, Nigeria. Ten commercial brands of teas (8 black teas and 2 green teas) were assessed for weight variation, moisture content and pH tests using standard methods. Extraction of caffeine was carried out and the identity determined by thin layer chromatography and melting points, respectively. High performance liquid chromatography (HPLC) method for analysis of caffeine was developed, validated, and applied to determine caffeine content in the tea brands. Results of the weight, moisture content and pH tests of the samples ranged from 2.07–2.33 g, 5.65–11.0 % and 4.9–5.5, respectively. Caffeine was isolated from all the samples and showed same Rf value (0.46) with that of the reference standard. Melting points ranged from 236.0–238.5 °C. Caffeine content ranged from 12.25–21.76 mg/g for black teas and 13.35–15.05 mg/g for green teas. The study provides information on the stability, acidity and caffeine content in some commercially available tea brands

    ANALISIS KEBUTUHAN PROJECT BOOK BERBASIS PJBL-STEAM PADA MATA KULIAH METODE EKSPERIMEN FISIKA

    The importance of experimental science for both researchers and students causes the physics experimental method course to be evaluated and developed, one of which is by analyzing fundamental problems and appropriate solutions in the form of finding appropriate teaching material needs to be developed. The type of research used is qualitative research with research subjects, namely students from the class of 2020. And the data collection technique is by conducting unstructured interviews with item questions, namely open questions. Data analysis was carried out descriptively so that the data would be arranged in a specific pattern and narratively draw conclusions. It was found that the fundamental problem of the course was the absence of learning guidelines so that learning took place unsystematically so that a teaching material could combine STEAM and PjBL. This research will be followed up with further research regarding the development of the STEAM-PJBL-based Project Book, which is expected to be able to answer all the problems contained in the course.Pentingnya ilmu eksperimental baik untuk peneliti maupun mahasiswa menyebabkan mata kuliah metode eksperimen fisika perlu di evaluasi dan dikembangkan salah satunya adalah dengan melakukan analisis permasalahan mendasar dan solusi yang tepat dalam bentuk menemukan kebutuhan bahan ajar yang sesuai untuk dikembangkan. Jenis penelitian yang digunakan adalah penelitian kualitatif dengan subjek penelitian yakni mahasiswa angkatan 2020. Dan teknik pengambilan data yakni dengan melakukan wawancara secara tidak terstruktur dengan butir pertanyaan yakni pertanyaan terbuka. Analisis data dilakukan secara deskriptif sehingga data akan di susun dalam pola tertentu dan membuat kesimpulan dengan cara naratif. Didapatkan bahwa masalah mendasar dari mata kuliah tersebut adalah tidak adanya pedoman pembelajaran sehingga pembelajaran berlangsung dengan tidak sistematis sehingga diperlukan sebuah bahan ajar yang dapat memadukan antara STEAM dan PjBL. Dengan adanya penelitian ini maka akan dilanjutkan dengan penelitian berikutnya mengenai pengembangan Project Book berbasis STEAM-PJBL yang diharapkan dapa menjawab semua persoalan yang terdapat dalam mata kuliah tersebut

    The bacteria Klebsiella pneumoniae is one of top aetiological agents associated with nosocomial infection, and it has gained its notoriety with the emergence of multidrug resistance strains. In this study, we evaluated the effect of lytic bacteriophage cocktail isolated from our local sewage as potential antimicrobial candidate against Gentamicinresistant Klebsiella pneumoniae. A total of five clinical-acquired K. pneumoniae isolates including a carbapenem-resistant K. pneumoniae (CRKP) strain showed resistance towards gentamicin (GN). Phages were isolated using double-layer agar method against clinical- and community-acquired K. pneumoniae as host strains. Phage characterization using PCR partial sequencing of different viral genes; Lysin, Major Capsid Protein (g23) and Tail Fiber Protein has suggested that these phages possibly belonged to Myoviridae (ɸKPaV04, ɸKPaV08, ɸKPaV12) and Podoviridae (ɸKPaV03, ɸKPaV10). The characterized phages was selected for cocktail have exhibited high titer and broad host range with 22-44% lysis towards a panel of 18 K. pneumoniae strains. The antimicrobial efficacy of a single phage cocktail administration showed 80% growth suppression of GN-resistant K. pneumoniae after 18 h of incubation. Suggesting the possibility of phage cocktail to be used against nosocomial infections by multidrug resistant bacteria including being an alternative to antibiotic GN in the treatment of CRKP infections

    This journal discusses the technical taxation issues related to companies undergoing bankruptcy. Companies experiencing bankruptcy are still required to report and pay taxes as usual, albeit with some differences in the conditions before bankruptcy occurs. During the bankruptcy period, the company must continue to pay taxes on the income received during its operational period, even though in bankruptcy, the company will prioritize repaying all debts to creditors. Various taxes still need to be paid in the situation of a bankrupt company, including Value Added Tax (VAT), Property Tax (PBB), and Income Tax. Companies undergoing bankruptcy also need to prepare Annual Tax Reports, which are mandatory, with tax rates varying depending on the type of reported income. Taxation issues are crucial in the context of companies experiencing bankruptcy. Companies must understand and manage their tax obligations well, even in bankruptcy
