The process of filling bunkers at PT PJB UBJ O&M PLTU 1 east java Pacitan is very dependent on coal handling system. In the existing system is still dependent on human resources as an operator, of course, very influential on human performance. The level of the bunker is a major problem for the continuity of the combustion process in the boiler. To support productivity, the authors make an innovative coal handling system design and monitor the level conditions in the bunker by using the PID (Proportional Integral Derivative) controller method to determine the level in the bunker. After that the condition is sent to the micro controller which then commands the conveyor and coal plough. The conveyor itself is driven by a stepper motor and the coal flow is driven using a servo motor. For combustion protection, there is a temperature sensor and a water pump in the bunker to extinguish. The level in the transmitted bunker serves as input to the PID and then the filling process is carried out by the conveyor to meet the demand for the bunker level. The accuracy rate in this system is 97.8% of the input data level of each bunker through an ultrasonic sensor. To make it more optimal all the information in the visual studio display.

The background of this research is the low learning motivation of students of SMK Negeri 1 Ngawen. This is indicated by the lack of ability to ask questions, thoroughness in doing questions, still cheating, the desire to find learning resources and so on. The purpose of this study was to determine the use of the scramble learning model to increase motivation to learn physics in students of SMK Negeri 1 Ngawen for the 2019/2020 academic year. This type of research is classroom action research. This research was conducted in two cycles. The subjects in this study were 31 students of class X TAB B of SMK Negeri 1 Ngawen in the 2019/2020 academic year, consisting of 16 female students and 15 male students. The data were collected using the observation method, the test method, the questionnaire method and the documentation method. After the data was obtained, it was analyzed using a percentage scale. The results of the study can be concluded that through the use of scramble learning models in learning physics can increase the learning motivation of students of SMK Negeri 1 Ngawen. This can be seen from the observation data of student learning motivation increased from 46.94% in the pre-cycle to 60.81% in the first cycle and increased again to 73.39% in the second cycle. The percentage of students' motivation questionnaire increased 58.06% in the pre-cycle to 72.90% in the first cycle and to 81.29% in the second cycle. This increase in learning motivation has an effect on improving learning outcomes. This is indicated by the increase in the average score of students. The mean score of students increased from 59.98 with completeness 38.71% in the pre-cycle to 77.66 with 80.69% completeness in cycle I and increased again to 85.97 with completeness of 93.97% in cycle II.

Penelitian ini bertujuan untuk meningkatkan hasil belajar IPS Terpadu melalui rekonstruksi pembelajaran diskusi kelompok menggunakan peta konsep bagi siswa kelas VIIIA MTs. Negeri 1 Pontianak tahun pelajaran 2017/2018. Jenis penelitian ini adalah penelitian tindakan kelas. Subjek penelitian ini adalah siswa kelas VIIIA MTs Negeri 1 Pontianak yang berjumlah 38 siswa. Hasil belajar siswa pra tindakan yaitu sebanyak 17 siswa (44,7%) tuntas dan 21 siswa (55,3%) belum tuntas dengan rata-rata kelas 68. Hasil penelitian menunjukkan persentase ketuntasan pada masing-masing siklus sebesar 70.3% dan 86,5% dengan nilai rata-rata 76,5 dan 88,1. Terjadi peningkatan ketuntasan belajar dari siklus 1 dan 2 sebesar 16,2%. Pelaksanaan rekonstruksi pembelajaran diskusi kelompok menggunakan peta konsep dapat menjadi alternatif pembelajaran IPS Terpadu di sekolah karena dapat meningkatkan hasil belajar siswa.
