Dampak Media Sosial Terhadap Perilaku Siswa Di Madrasah Aliyah Swasta Pinogaluman, Kabupaten Bolaang Mongondow Utara

The impact of social media such as YouTube, WhatsApp, Tiktok, Instagram, Facebook and so on has positive and negative impacts on students. Positive impacts, for example, will have creativity, have innovation in the development of science, and be used as an online business. The negative impact of foreign culture on students has reached an alarming stage because there is a tendency for students to have forgotten the culture of their own people. The culture of following along with Appearance or how to dress, following tick-tock trends, style of language in speaking, and shopping online, and always playing online games will affect the volume of brain cells so that the level of intelligence will decrease. Based on the above problems, the researchers conducted outreach to students in the private Madrasah Aliyah Hall, Pinogaluman District, North Bolaang Mongondow Regency with the aim of (1) strengthening and inculcating national character values for students in private Madrasah Aliyah, Pinogaluman District, Regency Bolaang Mongondow Utara. (2) Increasing students' awareness of their behavior while in the Madrasah environment. (3) Building a good cooperative relationship between teachers and parents of students. After carrying out the Mentoring and Socialization activities for students, we plan to do a mapping to find out how successful the teacher is in guiding his students

Isolation and detection of taxol, an anticancer drug produced from Lasiodiplodia theobromae, an endophytic fungus of the medicinal plant Morinda citrifolia

To determine the production of taxol from an endophytic fungus, Lasiodiplodia theobromae isolated from the medicinal plant Morinda citrifolia and also, to evaluate its cytotoxicity against human breast cancer cell line, taxol produced by the test fungus in MID culture medium was isolated for its characterization. The presence of taxol was confirmed by different chromatographic and spectroscopic analyses. The quantity of taxol produced by the fungus was calculated and estimated to be 245 μg/l. The fungal taxol was tested for its bioactivity against human cancer cell line (MCF-7) and the results showed that, the taxol possessed anticancer activity. The production of taxol was achieved from an endophytic fungus, L. theobromae. The screened taxol showed a potential toxicity against breast cancer cell lines. Fungal based production of taxol from an endophytic fungus would be the most desirable and alternate source of supply. This study proved that the fungal endophyte L. theobromae is an excellent candidate for an alternate source of taxol supply. Confirmations of the in vitro activity of taxol against human breast cancer cell lines should encourage further research. Furthermore, it is the first report of the screening of taxol from the fungus L. theobromae, isolated from the medicinal plant M. citrifolia.Key words: Endophytic fungus, Lasiodiplodia theobromae, anticancer drug, taxol production, cytotoxicity test

Space-time evolution of the average river flow in Transylvania Depression

Transylvania's physico-geographic factors distinguish it as a well-structured depression unit. Climate and relief features give it an unitary systemic functioning, which can be said about river water runoff. The three main rivers are well monitored by hydrometric stations located at the limits of the region. The length of flow strings has allowed real river flow analysis. Correlations between flow and time demonstrate the land’s systemic unity from a hydrological point of view. The variation of annual, seasonal and monthly averages indicates unitary variation laws. The values of the specific flow and the depth of surface runoff highlight the influence of the local factors, which incubate flow differentials

Austenite to ferrite transformation kinetics during continuous cooling

The austenite decomposition has been investigated in a hypo-eutectoid plain carbon steel under continuous cooling conditions using a dilatometer and a Gleeble 1500 thermomechanical simulator. The experimental results were used to verify model calculations based on a fundamental approach for the dilute ternary systems Fe-C-Mn. The austenite to ferrite transformation start temperature can be predicted from a nucleation model for slow cooling rates. The formation of ferrite nuclei takes place with equilibrium composition on austenite grain boundaries. The nuclei are assumed to have a pill box shape in accordance with minimal interfacial energy. For higher cooling rates, early growth has to be taken into account to describe the transformation start. In contrast to nucleation, growth of the ferrite is characterized by paraequilibrium; i.e. only carbon can redistribute, whereas the diffusion of Mn is too slow to allow full equilibrium in the ternary system. However, Mn segregation to the moving ferrite-austenite interface has to be considered. The latter, in turn, exerts a solute drag effect on the boundary movement. Thus, growth kinetics is controlled by carbon diffusion in austenite modified by interfacial segregation of Mn. Employing a phenomenological segregation model, good agreement has been achieved with the measurements
