Abstract

The deformation mechanisme in ductile – transition zone show microfracture cataclasis activities,intracrystalline deformations, twinning, kinking, solid-sate diffusion creep, recovery and recrystallisation. Thatactivities to extend the sense shear indication. Sense shear can see i.e porfiroclast, mica fish, porfiroblast, veins,strain shadow, strain fringe and boudin. Commonly sense shear indications to get the form of ellipsoid geometry.That geometry experience to development the structure along progressive deformations process. Thedevelopment of inclusion and fabric also occur at that process.

Abstract

Semarang city has experienced of the land subsidence that be caused by intake groundwater in confined aquiferabundant. The land subsidence happened during range of time 20 years, it’s critical boundary so that result theenvironmental damage. Hence needed a study of cause of the land subsidence. This study aim to know theposition of piezometric surface and also explain the mechanism hydrogeology when happened the landsubsidence. The study of spreading aquifer has been done by the analysis of secondary data which is in the formof drilling log data, piezometric surface and soil mechanics test obtained from PLG (Environmental Center ofGeology) Bandung. Later then, between the land subsidence and piezometric surface be overlay becamezonation. From the data made a analysis of cause of the land subsidence. This aquifer has the land subsidence.The land subsidence explainable with the experienced phenomenon fact for example degradation of piezometricsurface at confined aquifer and process of hydrocompaction. That process influenced by two factors that areassess the pore number (e) and specific gravity (Gs). The degradation of piezometric surface formed the trapezeof water table until 20 m from sea level with the mean 0.7 - 1.1 m/year. Hydrocompaction cause the degradationof number of mean pore 0.145 - 0.5 and specific gravity 0.009 - 0.073 . The degradation of piezometric surfaceand process the hydrocompaction cause the fast of land subsidence around 0.5 - 1.75 cm/year.

Abstract

This research aims to test the influence of the anime Haikyuu!! as a learning medium for students' interest in participating in extracurricular volleyball at SMA Negeri 1 Klari. The research method used was an experimental design with a one-group pretest-posttest approach. This research was conducted on 31 students of SMAN 1 Klari who took part in extracurricular volleyball. The data collection technique in this research is using a questionnaire instrument. Student interest data was collected through questionnaires before and after the intervention using the Haikyuu!! anime learning media. From the research results, data obtained before using learning media for the anime Haikyuu!!, the mean pre-test score was 106.29, with a median of 107.00, a standard deviation of 11.513, a minimum score of 83, and a maximum score of 128. After using learning media, the mean post-test score increased to 123.42, with a median of 125.00, a standard deviation of 12.326, a minimum score of 102, and a maximum score of 150. With this, it can be said that there was a significant change in students' interest after being influenced by the anime Haikyuu!! in extracurricular volleyball. This means that there is a difference between students' interests before and after being given treatment, so it can be concluded that there is an influence from the anime Haikyuu!! as a learning medium for residual interest in participating in volleyball extracurriculars at SMAN 1 Klari.
