Pengaruh Tri Sandya dan Komitmen Mahasiswa terhadap Coping Stress pada Mahasiswa Tingkat Akhir di Kampus STAHN Mpu Kuturan Singaraja
No full textThis study aims to evaluate and validate the influence of tri sandya on copingstress in final year students at STAHN Mpu kuturan Singaraja Campus; evaluateand validate the influence of student commitment on coping stress in final yearstudents at STAHN Mpu kuturan Singaraja Campus; and evaluate and validate theinfluence of tri sandya and student commitment together on coping stress in finalyear students at STAHN Mpu kuturan Singaraja Campus. In this particularresearch, quantitative and correlational approaches were used. It was determinedthat a sample size of 162 would be sufficient to accurately reflect all of thegraduating seniors at STAHN Mpu Kuturan. Trisanda and student devotion areexamples of elements that might be considered independent, whereas copingstress is the variable that is being studied. The information obtained from thesurveys and observations was put through an examination process that employedmultiple linear regression analysis. A t count of 2.938 indicates that there is a0.004 percent probability that TriSanna will have a good impact on themanagement of stress. It is possible to predict how well a student would do underpressure based on their degree of devotion (t-score = 13.641, probability = 0.0000.05). The effect of Hurricane Sandy and the amount of devotion shown bystudents results in an overall reduction in stress management of 81.7%. Accordingto the results of the research, students in their final year at the STAHN MpuKuturan Singaraja Campus exhibit a significant influence of Tri Sandya andstudent devotion in their ability to cope with stress..Keywords: tri sandya, student commitment, coping with stress

Fourier analysis of gapped time series: Improved estimates of solar and stellar oscillation parameters
No full textQuantitative helioseismology and asteroseismology require very precise measurements of the frequencies, amplitudes, and lifetimes of the global modes of stellar oscillation. The precision of these measurements depends on the total length (T), quality, and completeness of the observations. Except in a few simple cases, the effect of gaps in the data on measurement precision is poorly understood, in particular in Fourier space where the convolution of the observable with the observation window introduces correlations between different frequencies. Here we describe and implement a rather general method to retrieve maximum likelihood estimates of the oscillation parameters, taking into account the proper statistics of the observations. Our fitting method applies in complex Fourier space and exploits the phase information. We consider both solar-like stochastic oscillations and long-lived harmonic oscillations, plus random noise. Using numerical simulations, we demonstrate the existence of cases for which our improved fitting method is less biased and has a greater precision than when the frequency correlations are ignored. This is especially true of low signal-to-noise solar-like oscillations. For example, we discuss a case where the precision of the mode frequency estimate is increased by a factor of five, for a duty cycle of 15%. In the case of long-lived sinusoidal oscillations, a proper treatment of the frequency correlations does not provide any significant improvement; nevertheless, we confirm that the mode frequency can be measured from gapped data with a much better precision than the 1/T Rayleigh resolution
SDSS J212531.92–010745.9 : the first definite PG 1159 close binary system
No full textAims. The archival spectrum of SDSS J212531.92−010745.9 shows not only the typical signature of a PG 1159 star, but also indicates the presence of a companion. Our aim was the proof of the binary nature of this object and the determination of its orbital period.
Methods. We performed time-series photometry of SDSS J212531.92−010745.9. We observed the object during 10 nights, spread over one month, with the Tübingen 80 cm and the Göttingen 50 cm telescopes. We fitted the observed light curve with a sine and simulated the light curve of this system with the nightfall program. Furthermore, we compared the spectrum of SDSS J212531.92−010745.9 with
NLTE models, the results of which also constrain the light curve solution.
Results. An orbital period of 6.95616(33) h with an amplitude of 0.354(3) mag is derived from our observations. A pulsation period could not be detected. For the PG 1159 star we found, as preliminary results from comparison with our NLTE models, T eff ∼ 90 000 K, log g ∼ 7.60, and the abundance ratio C/He ∼ 0.05 by number fraction. For the companion we obtained with a mean radius of 0.4 ± 0.1 R, a mass of 0.4 ± 0.1 M, and a temperature of 8200 K on the irradiated side, good agreement between the observed light curve and the nightfall simulation, but we do not regard those values as final

Efektifitas Penerapan Project Based Teaching Module dalam Mengangkat Tingkat Kreativitas Belajar Siswa
No full textThe aim of this research is to see the level of effectiveness of implementing the project based teaching module on the topic of Culinary Basics. The uniqueness of this research lies in the responses of students who use the module. The module content is very interesting and varied so that it can increase student interest and stimulate creativity. Students become interested in reading because usually students only use books that are still rigid. The examples given in the module are very up to date. The method used in this research is a quasi experimental design research method with a control group and a random research sample. Data analysis techniques were carried out qualitatively (input criticism, suggestions) and quantitative (respondent assessments in the form of numbers on the questionnaire and observation sheet provided). The data collection technique used Pretest - Posttest Control Group Design which was analyzed using analysis prerequisite tests through normality tests and inferential statistics through t-tests (independent sample T-tests) to see differences in the average group learning outcomes. The population of this class is 40 people. The samples used were 30 with random sampling. Testing the effectiveness of using project based teaching module products in increasing the creativity of Dwi Tunggal Tourism Vocational School students was carried out using a two-tailed t-test. The tcount = 2.133 while the ttable value = 2.000, this shows that tcount is greater than ttable with a significance level of 0.05. So, the creativity of Dwi Tunggal Tourism Vocational School students who take part in learning using project based teaching modules is higher than the creativity of Dwi Tunggal Tourism Vocational School students who take conventional learning

No full textThe research aims to find out the significant effect of the ALC Model Assisted by Quizizz Media with Conventional Learning Models to Improve Mathematical Numeracy Literacy for IV elementary School Students. This research has quasi-experimental. The total population in this study was 161 students and research sample is 60 students with 30 experimental class students and 30 control class students. Based on the hypothesis that has been tested that, data analysis using independent t-test for N-Gain Score shows that df 30 + 30 - 2 = 58 with the value of tcount = 3,341 at a significant of 5%, the ttable value is obtained, namely 2,002. From the calculations results is known that tcount > ttable is 3,341 > 2,002 and Sig. (2-tailed) < 0.05 (0.001 < 0.05). This shows there is a significant difference in the effect of mathematical numeracy literacy between students who study with the ALC Model assisted by Quizizz media with the Conventional Model to improve mathematical numeracy literacy for 4 grade students of SD Cluster 3 Tejakula Village in the 2021/2022 academic year.
