Abstract

The Covid-19 pandemic that has occurred throughout the world, especially Indonesia, is a situation that requires everyone to work, study and carry out activities from home. In the world of education, the Covid-19 pandemic has had a major influence on learning activities from elementary to high (college) levels, where in the past learning could be done directly but currently requires all teachers, students and students to study online (on a network). Lecturers are required not only in mastering technology as well, but the delivery of material from lecturers also certainly has an important influence on students' understanding of the material. Lecturers must be able to make students understand what is conveyed in online learning. This research was carried out by the Civil Engineering study program at the Catholic Polytechnic of Saint Paul Sorong in the applied physics course. Research data was taken through a questionnaire distributed online to semester 1 students of the 2020/2021 academic year who had taken an online Applied Physics course with a total of 41 students as respondents. This research is descriptive quantitative. This study uses an instrument that is a questionnaire. The contents of the questionnaire relate to how much students are able to understand applied physics courses and student responses during online learning. The questionnaire used has been tested for validity and reliability using the SPSS version 23 application. Based on the research data, it can be concluded that the percentage of students' understanding of civil engineering in applied physics courses during online learning is 43% at most stating that online learning has been going well.

Abstract

A toxicity test is carried out to determine the death of the tested organism caused by the concentration of certain chemical compounds in the environment which is recorded as the value of lethal concentration (LC50). The main ingredients needed in this study are kerper fish (cyprinus carpio), water, and pesticides. The experiment was carried out 4 times, namely fresh, wayu 2 days, wayu 7 days, and wayu 9 days. 10 individual test animals were placed into each experimental container (vol. 4 liters). Water and test material were observed every 24 hours for 2 days, and during the experiment, the test animals were fed and oxygenated. The results showed that the resulting LC50 value for fresh was 3.55 x 10-4 ppm, the resulting LC50 value was 4.23 x 10-3 ppm, wayu 2 days was 8.69 x 10-3 ppm, wayu 7 days 5.68 x 10-3 ppm, and the resulting LC50 value for 9-day wayu is 1.026 x 10-2 ppm. The toxicity of matador pesticides against kerper fish that has been transmitted for 9 days is less effective. This happens because the pesticide is in direct contact with the air and the longer it is, the ability to kill the target animal is getting smaller. So if the pesticide is used, the toxicity will decrease so that the LC50 value will be higher

Abstract

Pada mesin 4 langkah terdapat sistim mekanisme katup masuk dan katup buang, tujuannya untuk pengaturan pemasukan campuran bahan bakar dengan udara dan pengaturan pengeluaran gas bekas pembakaran. Pada mekanisme katup ini diberi celah katup atau jarak diujung batang katup masuk dan katup buang tujuanya untuk mencegah pemuaian diwaktu mesin bekerja. Tujuan penelitian ini adalah untuk mencari dan menganalisa variasi celah katup masuk dan celah katup buang terhadap performa motor bensin. Metode yang digunakan dalam penelitian ini adalah metode kepustakaan dan eksperimen. Studi Pustaka dilakukan untuk mempelajari data sekunder dari referensi yang berkaitan dengan penelitian yang dilakukan. Sementara metode eksperimen dilakukan untuk mengetahui pengaruh variasi penyetelan katup terhadap putaran mesin. Pengujian dilakukan untuk posisi throttle standar (2,24 cm), posisi throttle sedang (2,11 cm) dan posisi throttle tinggi (1,82). Pengukuran putaran mesin dilakukan untuk katup 0,2 mm, 0,25 mm, dan 0,3 mm dengan 5 kali pengulangan. Hasil penelitian menunjukkan bahwa semakin tinggi posisi throttle (1,82 cm) dengan celah katup yang diperbesar maka semakin naik putaran yang dihasilkan. Sebaliknya dengan posisi throttle yang standar (2,24 cm) dengan celah katup yang standar akan menghasilkan putaran yang lebih lambat. Kata kunci: engine; katup; motor bensin. Daftar RujukanArimbawa, I.
