Abstract

The persistently inequality of development between major cities and surrounding areas caused the displacement process, that are transport of supplies or human itself (urbanization) or commonly known as the transportation. The government has set a number of policies to overcome transportation problems, for example construct a double track railway line. This study aimed to find an alternative solution to overcome the problems of transportation, especially railway line by optimizing of using single track railway line which is given the term semi-double track using Petri Nets and Max-Plus Algebra. In the previous research, a Max-Plus algebra model has been developed based on the hierarchical structure of semi-double track railway line. In this research, the model is simulated against the problem of delay.

Abstract

Kuliah Lintas Prodi adalah kegiatan mengikuti mata kuliah yang ditawarkan di luar mata kuliah Program Studi Matematika. Penelitian ini bertujuan untuk mengetahui hubungan antara keberlakuan sistem kuliah lintas prodi dengan keefektifan pembelajaran mahasiswa Program Studi Matematika Institut Teknologi Sumatera (ITERA). Hal ini melatarbelakangi permasalahan psikologis mahasiswa Program Studi Matematika angkatan 2017 dan 2018. Metode penelitian yang digunakan dalam penelitian ini adalah metode statistik dan pengujian hipotesis dengan Uji Korelasi Pearson dengan menggunakan variabel yaitu skor sistem kuliah lintas prodi dan skor keefektifan dalam belajar. Teknik pengumpulan data yang dilakukan adalah memperoleh data dari kuisioner dengan hasil 52 responden, yang berikutnya digunakan teknik penyajian skor hasil kuisioner. Dari hasil penelitian yang dilakukan maka dapat disimpulkan bahwa tidak terdapat korelasi yang signifikan antara sistem kuliah lintas prodi dengan keefektifan pembelajaran mahasiswa Program Studi Matematika Institut Teknologi Sumatera (ITERA).
