Persepsi Mahasiswa Terhadap Pemanfaatan Microsoft Teams Sebagai Platform Pembelajaran Kimia Pada Masa Pandemi Covid-19

Pandemi Covid-19 menstimulus terjadinya perubahan tata cara proses pembelajaran. Tidak diakomodasinya pembelajaran tatap muka, menstimulus munculnya inovasi pembelajaran berbasis digital. Salah satu inovasi tersebut yakni pemanfaatan Microsoft Teams sebagai platform pembelajaran kimia. Pada penelitian ini, dipaparkan persepsi mahasiswa terhadap platform tersebut yang ditinjau dari sisi aksesbilitas, easiness implementating, dan ketersediaan fitur. Sampel penelitian berjumlah 73 orang, yang masing-masing diberi angket persepsi dimana setiap angket terdiri dari 10 pernyataan dengan 5 opsi pilihan pada masing-masing kategori. Berdasarkan hasil penelitian, 93,15% mahasiswa beranggapan bahwa Microsoft Teams mudah diakses, 54,79% beranggapan mudah diimplementasi, dan 43,83% beranggapan bahwa fitur Microsoft Teams tersedia namun perlu updating. Data tersebut menunjukkan bahwa mayoritas mahasiswa mampu mengintegrasikan Microsoft Teams pada proses pembelajaran kimia

Guide to measurement of winds with instrumented aircraft

Aircraft measurement techniques are reviewed. Review of past and present applications of instrument aircraft to atmospheric observations is presented. Questions to be answered relative to measuring mean wind profiles as contrasted to turbulence measurements are then addressed. Requirements of instrumentation and accuracy, data reduction, data acquisition, and theoretical and certainty analysis are considered

Investigation on the Aha-Experience as an Indicator of Correct Solutions in Functional Analysis in Engineering Design

The functional analysis of technical systems is an important part of the design process. To further improve the design process, especially the functional analysis, it must not be viewed as a monodisciplinary process. To this end, cognitive factors such as the aha-experience must also be included in studies of analysis processes to a greater extent. This paper investigates the relationship between the occurrence of aha-experiences and the correctness of solutions in the analysis of a technical system. An aha-experience is a strong feeling of subjective certainty that accompanies the cognitive process of suddenly finding a previously unknown solution. For this purpose, a study on the functional analysis was evaluated. The results show that many identified subfunctions of the system under investigation were identified with an aha-experience and that these subfunctions are more often correct. The results also suggest that aha-experiences occur more often among students than among experienced design engineers. Especially among students, a positive relation of aha-experiences on the correctness of the identified subfunction can be seen. This offers potential for further investigations to make aha-experiences useful in design methods

HUBUNGAN MOTIVASI BELAJAR TERHADAP KETERAMPILAN PEMECAHAN MASALAH SISWA PADA METODE PRAKTIKUM

This study aims to analyze the relationship between students' learning motivation with the student's ability in solving problems faced. By doing this analysis, the teacher will have additional input in determining the appropriate method of the learning process in the laboratory. This type of research is an experimental research. The hope of this study is that students who have high learning motivation will have high problem solving skills. The research data was collected by using test and observation instruments. Based on the results of the study, students' learning motivation has a significant relationship with student problem solving skills with probability or sig value. 0.012 <0.05. Students with high learning motivation (upper grade ≥ 70) had average problem solving skills of 75.8 while students with low learning motivation (lower class <70) had an average problem of problem solving skills of 58.6. Thus, it can be concluded that students who have high learning motivation will have better problem-solving skills than students who have low motivation to learn on practical methods. Keywords: problem solving skills, practice methods, learning motivatio

Sensitivitas Ligan Ditizon terhadap Absorbsi Logam Zink dengan Teknik Emulsi Membran Cair

Contamination by zink metal can cause death in humans, animals, and plants. one of the uniqueness of this metal is that it can accumulate. consuming it at a low concentration does not cause death but if it happens continuously it will accumulate into high concentrate which can cause death. Ligand ditizon is one of the ligands which can absorb zink metal at low concentration, to be more efficient then used the liquid membrane emulsion technique which enables separation without going through the process of precipitation. Variations of concentration used is 1:3 v/v, 1:1 v/v and 3:1 v/v. Optimum absorption occurs at concentrations 1:3 v/v are 90.77%. Variations of liquid membrane emulsion duration used is 5 minute, 10 minute and 15 minute. Optimum absorption at duration 5 minute are 50.22%. Optimum absorption on the interaction between concentration and liquid membrane emulsion duration are 43.73% obtained F (392.76) >  Ftable (14.80).
