Abstract

Pencemaran lingkungan dapat menyebabkan berbagai permasalahan dalam kehidupan. Salah satu masalah pencemaran lingkungan di Indonesia adalah terjadinya penumpukan sampah di TPST Bantargebang Bekasi. Berdasarkan data empiris yang diperoleh, banyak mahasiswa yang belum mengetahui mengenai permasalahan penumpukan sampah di TPST Bantargebang. Oleh karena itu dilaksanakan penelitian ini yang bertujuan untuk mengetahui pemahaman mahasiswa Pendidikan Fisika Universitas Jember angkatan 2020, angkatan 2021, dan angkatan 2022 mengenai pencemaran lingkungan pada TPST Bantar Gebang di Bekasi. Penelitian ini menggunakan metode deskriptif dengan menyebarkan kuesioner kepada mahasiswa Pendidikan Fisika Universitas Jember dan dianalisis menggunakan microsoft exel. Hasil penelitian menunjukkan bahwa pemahaman mahasiswa Pendidikan Fisika Universitas Jember adalah “Kurang (D)”. Hal ini dibuktikan melalui nilai rata-rata sebesar 54,95 dengan nilai mediannya adalah 60. Pernyataan tersebut diperoleh berdasarkan tabel 3 terkait “Pengkategorian Nilai Hasil Kuisioner Mahasiswa”. Hal ini juga didukung dengan hasil wawancara yang menyatakan bahwa beberapa narasumber tidak mengetahui permasalahan penumpukan sampah di TPST Bantargebang Bekasi.

Abstract

The aim is the expected value of helium ions to determine its properties as a heat transmitter to reactors and chirogenic science. This research is non-experimental research using quantum mechanics literature study methods because there are many previous studies that are relevant to this research. Data on the expected value of electron momentum in helium ions is determined based on numerical calculations using the Matlab 2015a program to simplify calculations using ion expectation calculations in momentum. The results obtained are that the electron momentum value in the helium ion can provide an overview of the average momentum value of the helium ion electrons in momentum space. This research data also shows that in momentum space the expected value of electron momentum decreases as the principal quantum number (n) increases. This can be seen when n=1,l =0 then 3p0 = 1.3146, and when n=3,l =0 then 3p0 = 0.5098.
