Abstract

Salah satu jalur penjaringan mahasiswa baru Universitas Negeri Semarang (UNNES) adalah melalui Seleksi Nasional Masuk Perguruan Tinggi Negeri (SNMPTN). Mekanisme seleksi melalui SNMPTN didesain dengan berbagai kemudahan karena berbasis laman yaitu melalui http://penerimaan.unnes.ac.id. Terdapat fenomena yang menarik terkait dengan kecenderungan jumlah pendaftar mahasiswa baru UNNES yang perlu diteliti menyangkut usability laman http://penerimaan.unnes.ac.id/. Hasil analisis data peminat SNMPTN dan SPMU UNNES selama lima periode terakhir terhadap jumlah mahasiswa yang diterima memperlihatkan jumlah penerimaan mahasiswa UNNES lebih besar berasal dari peminat SPMU dibandingkan dengan peminat SNMPTN. Hal tersebut menunjukkan usability laman http://penerimaan.unnes.ac.id/ optimal.

Abstract

The completion of gravitational data inversion results in a smooth recovered model. GRAV3D is one software that can be used to solve 3D inversion problems of gravity data. Nevertheless there are still fundamental problems related to how to ensure the validity of GRAV3D to be used in 3D inversion. One approach used is to use lower bounds as inversion parameters. In this study lower bounds are set from  to . The results obtained show that the use of lower bounds decreases resulting in a larger data misfit which means that the more data that meets the tolerance calculation, the better recovered model produced.

Abstract

The mathematical modelling of geological structures, i.e. magma intrusion or dyke, has been done,  based on magnetic data with inversion techniques using MatLab. The magnetic equation is a non-linear equation, and completion is done using a linear approach to non-linear mathematical models of magnetic data using the Taylor expansion approach and Jacobi Matrix. The first step of this research is to make synthetic data forward modelling from the magnetic equation of magma intrusion or dyke cases without errors, and the next stepping then add errors to the data. The next step is to do an inversion to get the parameters sought, i.e. depth and angle of the magma intrusion, by giving initial guesses, and then re-correct iteratively until convergent results are obtained. Finally, parameters of slope dyke or thin magma intrusion and its depth can be determined. The results obtained indicate that this technique can be used to get physical parameters sought from magnetic data for simple geological cases, i.e. dyke and magma intrusion.

Abstract

This study aims to describe teachers' perceptions of practicum in physics learning, the implementation and obstacles of implementing physics practicum in online learning during the Covid-19 pandemic in the even semester of the 2019/2020 academic year and the odd semester of the 2020/2021 academic year. The research method is descriptive quantitative. The instrument used was a google form questionnaire. Samples were taken using simple random sampling technique, obtained 50 SMA / MA physics teachers in Central Java and East Java. The results showed that all teachers have the same perception that the application of practicum in learning physics is important. However, during the online learning period the teachers rarely applied practicum. Some teachers even argue that they haven't thought about how to implement online practicum. More than 50% of teachers have tried to do practicum during online learning. The types of practicum used are various, ranging from virtual laboratories, simulations, video demonstrations and hands-on. The implementation of practicum in online learning experiences various obstacles, both hardware (practicum material tools, computers / notebooks, smartphones, networks) and software, namely practicum procedures that are not understood by students and students' activeness control mechanisms.

Abstract

The interpretation of subsurface in the Semarang City with 3D inversion model using the Chi Fact algorithm has been carried out to reveal the subsurface especially related to the presence of groundwater basins. The gravity data model in this research uses 80 stations with a research area of 20 km2 which is specialized in the surrounding area of Kaligarang district. The results of the 3D inversion using the Chi Fact algorithm founded the distribution of subsurface rock density values in the Semarang City area ranging from 1.6 gr/cc to 2.98 gr/cc. The distribution of subsurface density values indicates the subsurface geological structure of the Semarang City area had a normal fault leading to the southeast.

Abstract

Studi literatur untuk mengestimasi temperature reservoir Gunung Lumpur Bledug Kuwu telah dilakukan menggunakan metode geotermometri larutan. Perhitungan temperature diperoleh dari hasil perhitungan empiris kandungan unsure-unsur kimia terlarut pada air panas Gunung Lumpur Bledug Kuwu. Kandungan unsure ini diperoleh dari hasil analisis sampel air panas dengan metode Atomic Absorption Spectrophotometer (AAS) yang dilakukan oleh Rizqiya 2014, berupa konsentrasi Na, K, Ca, Mg dan SiO2. Dari hasil perhitungan ini, estimasi temperature reservoir Bledug Kuwu berkisar antara 90.411 – 148.354 0C.
