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.
