The behavior of this two-stream wave in the plane perpendicular to the Earth's magnetic field is simulated with a two-dimensional two-fluid code, in which the electron inertia is neglected while the ion inertia is retained. The motions of the wave packets are analyzed by the phase-and group-velocity tracing technique. We found that the propagation senses of the phase-and group-velocities of the two-stream waves are opposite in the vertical direction. We point out that this peculiar behavior in the vertical direction may be caused by the fact that the horizontal phase speed is slower than the corresponding electron drift speed. We also found that the vertical group velocities of most wave packets are in the same direction as E 0. The result of this up-down asymmetry for the wave-packet motion is consistent with the radar observations. We reconfirm the previous conclusion: the background polarization electric field driving the electro-jet is responsible for the spectral asymmetries.

Data primer penelitian ini diperoleh dari jawaban pertanyaan wawancara terhadap enam pemimpin gereja lokal (Pendeta Ressort) dan yang menjadi populasi dan sampel sekunder adalah kurikulum Prodi Teologi Tahun 2021 yang sedang digunakan pada saat ini. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan metode wawancara terstruktur tentang keterampilan mengajar mahasiswa Prodi Teologi IAKN Tarutung tahun 2021 dan juga kajian teoritis terhadap kurikulum Prodi Teologi Tahun 2021 yang sedang digunakan pada saat ini. Hasil analisa jawaban responden menunjukkan bahwa indeks keterampilan mengajar mahasiswa berada pada angka 59,46 %, yaitu pada level 55 - 64 % atau pada kualifikasi ‘kurang terampil’. Berdasarkan hasil analisa jawaban respo...

This research use descriptive qualitative approach with documents analysis method. Data analysis carried out by doing interpretation the result of qualitative data analysis, after act of ranking grades and percentage be done. The act of data analysis is done since team of researcher start doing data classification (coding) within effective reading. Data interpretation is done by two stages, first interpretation of each data item and second, interpretation of all data. The result of data interpretation indicate insufficient family financial factor occupy in the highest sequence, which causing constantly dispute and no hope for living in harmonious anymore. The result of this research, then, posses coherence with Chapter 19 Government Regulation No. 9/1975 regarding Law Imp...

Primary data were obtained from answers interview questions to 15 respondents who know and understand the history of the local church. This study was a descriptive qualitative approach with structured interview methods about the implementation of church holistic stewardship in the period 1901-1937. The results of secondary data showed that the index of the benefits of their understanding of history was 72.54%. Based on the results, recommendations are given that church ministers and historical figures must continue to make intensive refreshment for the young generation of the church because it has been proven to have supported the life of the church and the family of the congregation. Keywords: analysis, the benefits of understanding, the history of the local church, HKBP Tampahan.
