Abstract

This study purposes to analyze the levels of coliform bacterial contamination and coliform bacteria types in water sources used by population in BTN Sosial housing in Jayapura Regency. The method used is the MPN method (Most Probable Number) and biochemical test methods. The results of the examination showed that there were <3 cells / 100 ml in the spring, 2300 cells / 100 ml of water flow, and in 24,000 cell / 100 ml water samples. The types of coliform bacteria found in the water sources are Citrobacterfreundii and Serratiamarcescens. Based on the results of the examination, it can be concluded that the water used by the people in the BTN Sosial housing contaminated with coliform bacteria exceeds the limit set by the Minister of Health of the Republic of Indonesia and needs further treatment to be consumed.

Abstract

The COVID-19 pandemic has caused the learning process to change, from face-to-face to online learning. Online learning requires optimal mastery of technology and the need for innovation in learning, especially in evaluating learning outcomes and online assessment. The use of Quizizz media is an alternative for evaluation with an attractive appearance far from being scary. This study uses a quantitative descriptive method that aims to determine student perceptions of the evaluation of learning outcomes accompanied by online assessment using Quizziz media. The research subjects are active students of chemistry education, Musamus University who have participated in an evaluation using quizizz. The instrument of this research is a questionnaire containing 20 questions based on 6 indicators and using a Likert scale. The research data was obtained from the results of the questionnaire that had been distributed through the google form application. The results showed that students' perceptions of the use of quizizz received a positive response of 87%. The conclusion in this study is that the use of quizizz as an evaluation accompanied by online assessment can be applied in chemistry education and can increase student motivation in learning.

Abstract

Keberadaan dan kelimpahan lempung alam (clay) di kabupaten Merauke sampai saat ini belum di manfaatkan dengan maksimal. Hal ini disebabkan karena kurang atau bahkan belum adanya penelitian dan informasi tentang karakteristik lempung alam tersebut. Lempung alam merupakan salah satu mineral alam yang mengandung silika dan partikelnya berukuran kurang dari dua mikrometer. Penelitian lempung alam Merauke dari Distrik Sota bertujuan untuk mendapatkan data awal berupa karakter fisika dan kimia karena selama ini belum ada kajian terkait hal itu. Lempung alam akan dipreparasi selanjutnya akan diidentifikasi karakternya menggunakan instrumen. Karakterisasi yang dilakukan meliputi kekristalan menggunakan X-ray Difractometer (XRD) dan analisa morfologi permukaan dengan Scanning Electron Microscope (SEM). Hasil karakterisasi menunjukan komposisi mineral kimia utama pada pada lempung asal distrik Sota adalah Illite dan silika Quartz.
