Kegiatan pengabdian kepada masyarakat yang dilaksanakan oleh Tim Pengabdian Kepada Masyarakat kolaborasi antara dosen pendidikan fisika FKIP UHAMKA dengan guru fisika di SMA Bina Dharma ini, bertujuan untuk meningkatkan pemahaman siswa terhadap materi fisika Mesin Carnott dan Hukum Kirchoff. Manfaat dari kegiatan pengabdian masyarakat yaitu terbentuknya video pembelajaran fisika berbasis tim teaching daring pada tiap – tiap sekolah dan menjadi kegiatan yang berkesinambungan. Manfaat tambahan yang didapatkan dari kegiatan ini yaitu terbentuknya tim pembuatan video pembelajaran berikutnya. Kegiatan pengabdian kepada masyarakat ini dilaksanakan dengan pembuatan video secara bersama – sama antara dosen dan guru, kemudian melalui proses editing. Metode kegiatan yang digunakan dalam pengabdian kepada masyarakat ini adalah metode tim teaching secara daring. Evaluasi kegiatan yang digunakan dalam pengabdian masyarakat ini adalah aspek pengetahuan dan minat, berdasarkan data angket kepada siswa didapat bahwa video pembelajaran hasil kolaborasi dosen dan guru memudahlan siswa saat pembelajaran daring dengan hasil responden 93,5 %.
Simulation of radiation calculation of black body by using the interpolation method is designed to facilitate the determination of radiation in black matter efficiency. Fortran programming languages are chosen for computational processes. The calculation program that has been designed is able to calculate the efficiency of black body radiation easily and quickly with a fairly small error rate of 0.5\%. The light radiation spectrum of objects is around 1000, 1100, 1200, and 1300 $^{\circ}$C. The $x$ axis shows the wavelength, while the $y$ axis shows the intensity or strength of light. If we pay attention to the curvature of 1000 $^{\circ}$C, along with the increasing frequency of light, the intensity of light is also getting stronger aka more bright. But at certain light frequencies, the line reaches the peak, and after that the light intensity drops dramatically. At temperatures of 1200 $^{\circ}$C and 1300 $^{\circ}$C, even though the temperature rises, the outline of the line graph is similar to the line 1000 $^{\circ}$C. This is in accordance with the existing theoretical and experimental results.
This paper reports the process and the results are supplemented by material microwave absorber characterisation \ce {La_{0.67}Sr_{0.33}Mn_{0.8}Ni_{0.2}O3} which has been synthesised by sol gel method. Results refinement of the XRD data showed that the material \ce {La_{0.67}Sr_{0.33}Mn_{0.8}Ni_{0.2}O3} have formed a single phase. From the results of using the software refinement High Score obtained crystal size on sample of 21.18 nm. Number of spin concentration in the sample at ESR test results showed a decrease when doping Ni increased, the area under the curve of absorption decreases as 388.718. This is due to the substitution of \ce {Ni^{2+}} ions \ce {Mn^{3+}} ions thus inhibiting electron hopping of electrons $\mathrm{e_g}$ (\ce {Mn^{3+}} ion) to $\mathrm{t_{2g}}$ (\ce {Mn^{4+}} ion) in the mechanism of double exchange so that the spin of the electrons will $\mathrm{t_{2g}}$ antiparallel. Competition between ferromagnetic properties with antiferromagnetic spin make will change the direction so that the sample magnetisation will decrease and the magnetic moments become random. ESR results are used to confirm the results of the VNA. Microwave absorption ability is indicated by the value of reflection loss on the sample is $-66.67$ dB.
This study aimed to determine the correlation between boarding schools and spiritual quotient (SQ) on learning outcomes. The method used was a survey with quantitative approach, because there are two independent variables, then use path design analysis. The results obtained, the first, there was a significant relationship between the pesantren with the student learning outcomes, t count = 2,22 > t table(0,05) =1,69, a contribution of the boarding school environment to learning outcomes was 36.1% with the category enough. The second, there was a significant relationship between spiritual quotient with a physics student learning outcomes, t count = 4,3 > t table (0,05) = 1,69, a contribution spiritual abilities physics quotient on learning outcomes by 36% with the category enough. The third, there was a significant relationship between the pesantren and spiritual quotient on learning outcomes t count ≥ t table(0,05) =1,69.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
