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

Electricity is needed by the whole society. Sasnek village is one of the villages located in Sawiat District, South Sorong Regency, West Papua Province. Sasnek village is very clear and inhabited around 100KK. This village has not been served by electricity until now.  Micro-hydro power plants are small-scale power plants whose capacity presents between 100 W to 100 kW. This study will be used for loading stages with a 12 Volt DC power capacity, because it is one of the most efficient, young and safe ways. Measurement of air discharge, discharged by 2 liters / second from a measurement area of 5 m2 and an average air speed of 00.65 m / d.  However, due to the condition of the river water flowing throughout the year in the sense of never dried, then used a correction factor of 0.75. Thus the flow that can be used is equal to 0.65 m3 / d. Based on the analysis of the potential contained in Sasnek PLTMH, it can be calculated Distribution Grid sourced from Sasnek PLTMH is 10 KW.With the careful planning so that the results of its implementation will give a positive impact to be meeting the needs of electricity in the village and surrounding villages sasnek.
