This research aims to describe the violence acts prevention through counseling service by using a problem-solving approach to improve the students’ selfcontrol. This study is a quantitative research with an experimental design. The population consisted of Senior High School (SHS) students in Padang, Indonesia, and the sampling technique was cluster random sampling. Data collection was performed through the use of Firman and Yennikarneli's questionnaire (2017) which validity and reliability have been approved. Data analysis was performed through a descriptive method and the Wilcoxon Signed Rank Test. Based on the results of the analysis, it was found that violent acts prevention through counseling service by using a problem-solving approach is effective in improving high school students' self-control.","PeriodicalId":240056,"journal":{"name":"Proceedings of the Proceedings of The 5th Annual International Seminar on Trends in Science and Science Education, AISTSSE 2018, 18-19 October 2018, Medan, Indonesia","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115141457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concrete is made in the form of cubes 15 x 15 x 15 cm with the standard SNI K-175 with a composition of 1: 2: 3 cement mixture with FAS 0.5. In this study, variations in the composition of red sand (fine aggregate) were made by 0%, 5%, 10%, 15%, 20% of the weight of the fine aggregate used and the variation of red sand grain size of 80 mesh, 100 mesh, 120 mesh. After the concrete is 24 hours old, the mold is opened and given the code number as desired and treated in a water bath. After going through the immersion period 28 days later the pressure strength was tested and the XRD test. From the results of the study obtained the mechanical properties of the maximum concrete pressure strength test at a composition of 5% along with a decrease in the size of the red sand grain size (80 mesh, 100 mesh, 120 mesh) with pressure forces of 31.9 MPa, 35.4 MPa, and 35.5 MPa, respectively. This goes beyond the force of pressure set by the Indonesian National Standard Agency. XRD testing on concrete after smoothing, from the results of the XRD test obtained elements such as SiO2, Ca (OH) 2, CaO and Ta2O5 show that the graph shows a high silicon intensity value. Addition of red sand fine aggregate has an impact on improving the quality of concrete (the strength of pressure from SNI k-175 becomes K-400).","PeriodicalId":240056,"journal":{"name":"Proceedings of the Proceedings of The 5th Annual International Seminar on Trends in Science and Science Education, AISTSSE 2018, 18-19 October 2018, Medan, Indonesia","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126466322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concept of system resilience that functions for machines that move normally and can return to a stable state after a disturbance occurs. Oscillation of changes in speed and oscillation changes in the electric power system occur due to disturbances. Disturbance in electricity causes an electric current that works on the system beyond the nominal current. The effect of the current disturbance will have an impact on changes in the current torque parameters that cause prime-over instability when the generator is operating. This instability will affect the rotor speed and the voltage emitted by the generator. Dynamic oscillation repair testing by applying phase compensation control and PID-Controller on the excitation system is done to see the response of speed and voltage response when the system is experiencing interference. Observation of system oscillation response using matlab simulation to see system performance. The simulation results show that dynamic stability improvement with phase compensation method can reduce oscillation speed and voltage within 6 seconds and the use of PID-controller can reduce the speed and voltage in 3 seconds. The phase compensation method and PIDcontroller applied to the excitation system can reduce the electric power system oscillation.","PeriodicalId":240056,"journal":{"name":"Proceedings of the Proceedings of The 5th Annual International Seminar on Trends in Science and Science Education, AISTSSE 2018, 18-19 October 2018, Medan, Indonesia","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131281864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
