Tahap-Tahap Pendidikan Karakter Dalam Pemikiran Ki Ageng Suryomentaram Dan Relevansinya Dengan Pendidikan Akhlak Islam
No full textMorality shows people’s life quality and how the moral education could influence them. The religious people have assumption that religion always teaches the followers to do goodness and forbid them from doing badness. Islam, in the context of Indonesia, is of course influenced by the real condition of the society. In relation to this, there is Javanese philosopher, Ki Ageng Suryomemtaram, who thought the character building that is still relevant. He thought, “feeling is the center of everyone’s personality”. Based on his idea and feeling, he divides them into four dimensions of lif
Meningkatkan Etika Berbicara Dengan Teman Sebaya Melalui Bimbingan Kelompok Dengan Teknik Modelling pada Siswa SMP
No full textThis study aims to (1) Describe the actions of counselors in using group guidance services with modeling techniques to improve the ethics of talking with peers. (3) Describe the improvement of the ethics of talking with peers by using group guidance services with modeling techniques for students of class IX.B SMP 1 Pancur Rembang Semester II Academic Year 2017/2018. Based on the results of the study the ethics of talking with peers in pre-cycle obtained a score of 130 on average 16.25 percentage 32.25% entered in the category of very poor (SK), cycle I obtained a total score of 533 an average of 22 percentages 44% entered the category less ( K), and in cycle II there was a total score of 939 on average 39 percent 78% in the good category (B). So from the pre-cycle, cycle I, cycle II, the results were 32.25% to 78%, so there was an increase of 45.75%. Based on the results of the discussion it can be concluded that group guidance services with modeling techniques can improve the ethics of talking with peers in class IX.B SMP 1 Pancur Semester II Academic Year 2017/201
ANALISIS EFEK HALL PADA BAHAN PENGHANTAR LISTRIK
No full textHall Effect experiments on electric conductor
materials, silver and tungsten metals, have been carried out at room temperature using Leybold's Hall Effect apparatus.
From this experiments give following result : Hull constant, RH' and carrier concentration, n, of both silve? and tungsten samples, these values are in a good agreement with the results extracted from earlier experiments by other persons. And the negative values of RH , indicates negative charge carries in metals. This can be explained by "energy band theory".
If one places a conductor carrying acurrent I in a transverse magnetic field induction B, an electric field will be induced in the direction normal to both I and B, known as Hall effect.
The Hall potential VH to rise proportional with current I and megnetic field B given by the equation :
V = const. B I (1)
The theoretically,derived formula for Hall potential VH in the conductor (of thickness d) is
1 1
B I
H n e d
with n the charge carrier concentration.
The material-dependent factor (1/ne) is designated as Hall constant R
In equation (2) all quantities except n are accessible to measurement so that the Hall effect enables the charge carrier concentration to be determined by experiment.
In these experiments, Hall effect, using Leybold's Hall effect apparatus with silver and tungsten metals as samples. The potential Hall VH record for magnetic field B constant on the current I to variation.
With linear regression, applied to equation (2) we get the Hall constant RH and from these value the charge carrier concentration can be determined.
From these experiments given results :
R • = - (8,52 ± 0,08) 10-11 m3 C-1
n = (7,19 ± 0,07) 10" II1-3
and
R • = - (15,58 ± 0,07) 10-11 ma C-1
n = (3,97 ± 0,02) len m 3 for silver metal
for tungsten metal
These values are in a good agreement with the results extracted from earlier experiments by other persons.
For silver and tungsten metals, the Hall constant RH determined in practice its negative value; indicating that majority charge carrier two both silver and tungsten metals is electron. This can be explained by 'energy band theory'.
Telah dilakukan percobaan Effek Hall pada bahan
penghantar listrik, logam perak dan logam tungsten, pada suhu kamar dengan menggunakan peralatan Effek Hall buatan Leybold Jarman,
Dari percobaan diperoleh bahwa konstanta Hall, RH, dan konsentrasi pembawa muatan listrik, n, mempunyai nilai yang yang sesuai dengan hasilpercobaan yang dilakukan oleh orang lain sebelumnya untuk kedua sampel tersebut. Dan nilai negatip pada tetapan Hall RH yang diperoleh, untuk logam perak dan logam tungsten, mehunjukan bahwa mayoritas pembawa muatan listrik dalam kedua logam tersebut adalah elektron. Hal ini dapat dijelaskan melalui 'teori pita tenaga".
Hasil-hasil tersebut menunjukan persesuaian dengan
hasil percobaan yang dilakukan oleh orang lain.
Untuk logam perak dan tungsten, tetapan Hall. RH yang diperoleh mempunyai nilai yang negatip; ini berarti mayoritas pembawa muatan listrik dalam kedua logam tersebut adalah elektron. Hal ini dapat dijelaskan melalui 'teori pita tenaga*
