Abstract

This research aims to examine the strategies used by Islamic religious education teachers at SMP Negeri 03 Tungkal Ulu, Jambi Province, in forming religious tolerance in students. The issues studied are how students develop attitudes of tolerance towards various beliefs, teacher strategies for teaching religious tolerance, and identifying factors that support and hinder the formation of religious tolerance in students. This research is a qualitative research. The attitude of religious tolerance at SMPN 03 Tungkal Ulu, Jambi Province has reached a good level, with mutual respect, protection and respect for differences of opinion between individuals. PAI teacher strategies also involve inter-religious dialogue when there are differences in beliefs or when non-Islamic students take PAI lessons. Even though there are still several obstacles, the efforts made at SMPN 03 Tungkal Ulu, Jambi Province to build religious tolerance are quite encouraging. Penelitian ini bertujuan untuk mengkaji strategi yang digunakan oleh guru pendidikan agama Islam di SMP Negeri 03 Tungkal Ulu, Provinsi Jambi, dalam membentuk toleransi beragama pada siswa. Persoalan yang dikaji adalah bagaimana siswa mengembangkan sikap toleransi terhadap beragam keyakinan, strategi guru untuk mengajarkan toleransi beragama, serta mengidentifikasi faktor-faktor yang mendukung dan menghambat dalam membentuk toleransi beragama pada siswa. Penelitian ini merupakan penelitian kualitatif. Sikap toleransi beragama di SMPN 03 Tungkal Ulu Provinsi Jambi telah mencapai tingkat yang baik, dengan adanya saling menghargai, mengayomi, dan menghormati perbedaan pendapat di antara individu-individu. Strategi guru PAI juga melibatkan dialog antar beragama ketika terjadi perbedaan keyakinan atau ketika siswa non-Islam mengikuti pelajaran PAI. Meskipun masih terdapat beberapa kendala, upaya yang dilakukan di SMPN 03 Tungkal Ulu Provinsi Jambi dalam membangun toleransi beragama cukup menggembirakan.

Abstract

Pembelajaran yang baik apabila guru mampu mengelola kelas dengan pembelajaran yang inovatif dengan menggunkan metode pembelajaran yang dapat membuat siswa berusaha sendiri seperti  pada pembelajaran IPA dengan  menggunakan metode Problem Based Learning dan metode pembelajaran saintifik. Penelitian ini bertujuan untuk mengalisis efektivitas metode Based Learning dengan Pembelajaran saitifik terhadap hasil belajar. Penelitian ini menggunakan penelitian eksperimen semu, dengan menggunakan non equivalent control group design. Populasi dalam penelitian berjumlah 419 sampel  52 orang siswa. Data hasil  penelitian dikumpulkan dengan menggunakan angket dan observasi. Teknik analisis data yang digunakan yaitu SPSS versi 26 dengan Teknik analisis data Independent Sampel T-test ,analisis data terdiri dari uji normalitas, uji homogenitas dan uji t. Hasil penelitian menemukan nilai signifikansi sebesar 0,034 dengan kata lain yakni 0,034 < 0,05 sehingga H0 ditolak dan H1 diterima yakni ada perbedaan peningkatan hasil belajar IPA tentang organ pernapasan manusia antara siswa yang diajarkan dengan pembelajaran Problem Based Learning dengan yang diajarkan pembelajaran saintifik sehingga dapat disimpulkan bahwa terdapat perbedaan efektifitas antara kelas yang menerapkan metode pembelajaran Problem Based Learning dengan  kelas yang menerapkan metode pembelajaran saintifik terhadap hasil belajar kelas V di Kecamatan Suppa Kabupaten Pinrang. Good learning if the teacher is able to manage the class with innovative learning using learning methods that can make students try on their own, such as in science learning using the Problem Based Learning method and scientific learning methods. This research aims to analyze the effectiveness of the Based Learning method with scientific learning on learning outcomes. This research uses quasi-experimental research, using a non-equivalent control group design. The population in the study amounted to 419 samples of 52 students. Research data was collected using questionnaires and observations. The data analysis technique used is SPSS version 26 with the Independent Sample T-test data analysis technique, data analysis consists of a normality test, homogeneity test and t test. The results of the research found a significance value of 0.034, in other words, namely 0.034 < 0.05, so H0 was rejected and H1 was accepted, namely that there was a difference in the increase in science learning outcomes regarding human respiratory organs between students taught Problem Based Learning and those taught scientific learning so it can be concluded that there is a difference in effectiveness between classes that apply the Problem Based Learning learning method and classes that apply scientific learning methods on class V learning outcomes in Suppa District, Pinrang Regency.

Abstract

The problem encountered while developing the RKX-200TJ/booster is the measurement of mass vehicle (center of gravity). The thrust line of the rocket booster does not coincide with the center of gravity can induce a pitch disturbance. By controlling the pitch parameter, the pitch disturbance phenomenon can be minimized. In this paper is presented the flight performance and dynamics analysis and the design of pitch and roll control system for RKX200TJ/booster during rocket booster and climb phase. The result indicates that the pitch disturbance can be reduced until decrease about 27% whereas roll angle ( ) can be damped at zero level ( ). Pitch angle ( ) can be maintained at angle 5° for climb phase. Although the one of moment arm case shows the static instability and uncontrollability during rocket booster phase, the control system can control vehicle the further phase. This simulation presented in X-Plane and Simulink. The PID controller is selected in control system design.

Abstract

The performance of rocket flight can be evaluated from flight test data. The difference between flight prediction simulation and flight test data will indicate the accuracy of rocket identification model. Several factors cause rocket flight test deviated from flight prediction. Atmospheric disturbances and thrust scale are major factors causing inaccuracy rocket model. Another obstacle encountered is lack of flight data measured from flight test although there are still several data are obtained from accelerometer, altitude sensor, and GPS. Rocket performance identification can be obtained by conducting simulation of flight test data. This paper addresses identification of RX-450 series-5 in terms of flight performance. Thrust profile is generated from accelerometer recording data, and this parameter become an input for rocket simulation. The wind data is treated as atmospheric disturbance. The wind data is augmented by GPS on air balloon, and further processed become wind speed and win direction. Comparison both data can be explained as follow: During boost-phase, flight test data of the rocket shows maximum acceleration of 14.5g, on the other hand flight identification gives 13.4g. Rocket flies for 157.36 s in flight test whereas rocket identification predicts the max of flight time is 162.8 s. The rocket has max-range in 86.06 km measured by GPS data whereas flight identification estimates the max-range is 82.78 km. The flight identification indicates that the roket was deviated 6.25° from initial azimuth of the launcher direction. This 6.25° of deviation leads the rocket flies in Y-direction with the distance of 9.02 km. Flight test data shows that the rocket slides its direction 6° to the right of the initial launch azimuth.
