Abstract

This study aims to determine whether or not there are differences in the results of social studies learning material on the history of the proclamation of Indonesian independence of students taught by learning methods. Learning Starts With A Question and Question Student Have. This study uses a quantitative method with the type of approach "quasi-experimental" and "experimental design posttest-only control group" research sample consisted of 30 students in the experimental class I and 30 students in experiment II. This sampling uses a sample cluster. Based on the calculation results obtained an average of X1 66.3 and an average value of X2 93.5 after which the t-test was calculated, then the t-count was obtained at 9.03 with a dk of 58 then obtained a ttable with a significance level of 2.02 . Because tcount> ttable, it can be concluded that H0 is rejected and H1 is accepted, it can be concluded that there are significant differences in the use of learning strategies Learning Starts With A Question And Question Student Have.

Abstract

Gangguan scram yang terjadi pada pengoperasian reaktor nuklir akan mengganggu kelancaran operasi reaktor. Ketika reaktor sedang dimanfaatkan untuk mengiradiasi sampel atau untuk melaksanakan penelitian dan tiba-tiba reaktor scram, proses iradiasi dan proses penelitian akan terganggu yang selanjutnya akan mempengaruhi hasil. Makalah ini mengevaluasi gangguan scram yang terjadi pada pengoperasian reaktor serba guna GA SIwabessy (RSG-GAS) pada kurun waktu 2009 – 2014. Evaluasi dilakukan dengan mengumpulkan dan mengidentifikasi data gangguan scram kemudian menginvestigasi dan mengevaluasi penyebabnya.  Dari hasil evaluasi diketahui bahwa telah terjadi gangguan scram sebanyak delapan puluh delapan kali terdiri dari 34 kasus terputusnya pasokan listrik PT PLN, 9 kasus penanganan yang salah oleh operator, dan 45 kasus yang lain terkait dengan kegagalan komponen sistem proteksi reaktor. Dapat disimpulkan bahwa kerusakan dengan frekuensi paling banyak berasal dari kegagalan komponen sistem proteksi reaktor. Diperlukan pengkajian lanjut berkaitan dengan keandalan SPR agar pengoperasian reaktor dapat dilaksanakan dengan lancar dengan jumlah gangguan minimal bahkan pengoperasian tanpa gangguan.ABSTRACT EVALUATION ON SCRAM DISTURBANCES AT THE GA SIWABESSY MULTI PURPOSE REACTOR OPERATION. Scram occurred during reactor operation will disturb the operation of the reactor. In the course of sample irradiation or research processes an advertently scram will develop instability and shortcoming causing poor result of irradiated sample.  This paper is aim to evaluate scram disturbances during the GA Siwabessy reactor operation for a time frame of year 2009 – 2014. The evaluation is carried out by compiling data disturbances followed by investigating and evaluating their causes. From the evaluation result it is known that reactor scram occurred within above period are 88 times including scram due PLN electrical  power supply failed of 34 times,  scram due component failure of 45 times and scram due human error of  9 times. Then it can be concluded that components failure considered as main disturbances. Assessment components reliability is a must. While disturbances of PLN electrical power supply and disturbance of human error should be avoid by continuously improving human knowledge and experience

Abstract

AbstractThe research was started from a survey that students experienced struggles in participating the learning that wasalso a desire to find out the obstacle factors in the high jump material. The purpose of this study was to determinethe error and difficulty factors experienced by students in participating the high jump straddle style of high jumplearning. This study used survey method with observation sheets and questionnaires. The subjects were fifth gradesstudents of State Elementary School in Pengasih, Wates, Kulon Progo. The data analysis employed quantitativedescriptive analysis. The results showed that the percentage of data classification of straddle high jump as follows;the most error factor was when floating, the second error factor was landing, the third error factor was pushing, andthe fourth error factor was the beginning.Keywords: error, straddle high jumpAbstrakPenelitian dimulai dari suatu survei bahwa siswa mengalami hambatan dalam mengikuti pembelajaran juga suatukeinginan untuk mengetahui faktor penghambat itu dalam materi lompat tinggi. Tujuan penelitian ini adalah untukmengetahui faktor-faktor kesalahan dan kesulitan yang dialami oleh siswa dalam mengikuti pelajaran lompat tinggiguling perut. Penelitian ini menggunakan metode survei dengan lembar pengamatan dan angket. Subyek penelitianadalah siswa kelas V Sekolah Dasar Negeri III Pengasih Wates Kulon Progo, analisis data menggunakan analisisdeskriptif kuantitatif. Hasil penelitian menunjukkan bahwa klasifikasi data persentase pelaksanaan lompat tinggiguling perut sebagai berikut; faktor paling banyak kesalahan adalah saat melayang, tingkat kesalahan kedua adalahmendarat, tingkat kesalahan ketiga adalah tolakan, dan tingkat kesalahan keempat adalah awalan.Kata kunci: kesalahan, lompat tinggi guling perut
