UJI AKTIVITAS ANTI BAKTERI EKSTRAK ETANOL 96% DAUN TEH-TEHAN (Acalypha siamensis) PADA BAKTERI Escherichia coli DENGAN MENGGUNAKAN METODE CAKRAM

Teh-tehan (Acalypha siamensis) is a plant that has many branches including a bush with a height of 1-2 m. Escherichia coli bacteria can be found in the human intestine, most of these bacteria are harmless, but some can cause serious poisoning in humans such as diarrhea. The purpose of this study was to determine the antibacterial activity of the ethanol extract of tea-tea leaves (Acalypha siamensis) against Escherichia coli bacteria using the disc method. This research is descriptive by using the ratio of the extract concentration of 20%, 30%, 50%, and 80% with a positive control of chloramphenicol and a negative control of aquadest. he results showed that the concentration of ethanol extract had antibacterial activity. Escherichia coli bacteria gave the highest inhibition zone at a concentration of 80% with an inhibition zone diameter of 12.8 mm while the control chloramphenicol was 28.5 mm. Based on the ANOVA data analysis test that there is a significant difference in antibacterial inhibition

Self-help for stress and burnout without therapist contact: An online randomised controlled trial

Interventions designed to reduce stress and burnout may be costly and access is limited. This study examined the effectiveness of a self-help book, using Acceptance and commitment therapy (ACT) to target stress and burnout in a randomised controlled online trial without any therapist contact. Participants were recruited through a newsletter of a health insurance company. Participants ( N = 119) who reported at least moderate levels of stress were randomly assigned to an immediate intervention ( n = 61) or a waitlist group ( n = 58). Measures before and after the intervention assessed stress, burnout (primary outcomes), depression, well-being, emotion regulation (secondary outcomes) and ACT-specific constructs. Compared to the waitlist group, participants in the immediate intervention group reported lower stress and burnout and higher psychological flexibility at post-assessment. Effects between groups were large for stress ( d = 0.9), moderate to large for burnout ( d = 0.5–0.8) and large for psychological flexibility ( d = 0.8). All primary and most secondary outcomes and ACT processes continued to improve in the 3-month-follow-up period. Results suggest that an ACT self-help book without any therapist contact is effective in reducing stress and burnout for various occupations. Thus, it may provide a cost-effective public health intervention for reducing stress and burnout

STRATEGI SUPERVISI PENDIDIKAN DI SEKOLAH DAN MADRASAH (Educational Supervisions strategy In Schools and Madrasah)

Kualitas guru dan tenaga kependidikan salah satu penentu keberhasilan dan kualitas peserta didik pada Lembaga Pendidikan di sekolah. Supervisi salah satu kegiatan yang dapat menjaga kualitas kinerja guru dan tenaga kependidikan. Supervisi merupakan kegiatan pembinaan dan pengawasan yang dilaksanakan pengawas sekolah dan kepala sekolah terhadap guru dan tenaga kependidikan untuk meningkatkan kualitas dan kopetensi kerja. Kegiatan supervisi salah satu cara meningkatkan kualitas pembelajaran peserta didik, sehingga perlunya stratgi pelaksanaan kegiatan dengan sebaik mungkin. Sehingga penerapan supervisi memperhatikan pendekatan, teknik dan aspek yang harus di jalankan, agar proses supervisi berjalan dengan baik

La lettura farà emergere la sorprendente contemporaneità della studiosa, testimonial di una medicina estetica di genere, in anticipo rispetto ai tempi e leader di una cosmetica che precorre le idee portanti, i fattori chiave e le linee di sviluppo della moderna cosmetologia

Arrays of P=O dipoles as a recurrent structural motif in dis-diphenylphosphine oxides, established from powder x-ray diffraction

Rationalization of the solid-state structural properties of odd members (n = 3, 5, 7) of the series Ph2P(O)(CH2)nP(O)Ph2 leads to insights concerning the structural determinants of this class of material, particularly with regard to the formation of preferred arrangements of P═O dipoles. The odd members of this series are recalcitrant to the formation of single crystals of suitable size and quality for single-crystal X-ray diffraction, and modern techniques for carrying out crystal structure determination directly from powder X-ray diffraction data were essential for determining the structural properties of these materials. In the present work, nonsolvate crystal phases of the materials with n = 3 and 5 were prepared by appropriate solid-state desolvation processes (starting from hydrate and toluene solvate phases, respectively), yielding microcrystalline powders of the nonsolvate phase in each case. Structure determination was carried out directly from powder X-ray diffraction data, employing the direct-space genetic algorithm technique for structure solution followed by Rietveld refinement
