Abstract

Ergonomic physical environment workshop is one of the supporting factors in the process of vocational learning, especially the practicum. The main problems in this activity are the ergonomic conditions of the physical environment workshop is less conducive thermal comfort aspects, minimal lighting, disturbing noise, and poorly designed workspace such as oil fluid and equipment scattered on the floor. This condition can lead to fatigue, negligence and accidents, which will affect the development and improvement of students’ competence. The purpose of this study is to know the description and information about ergonomic standard of ideal physical environment including thermal, lighting, acoustic (noise), and work room design. This study is a quantitative approach with survey method. The technique of collecting data uses observation and direct measurement. The result of descriptive analysis and conclusion shows that; (1) the thermal comfort is at 32.10 °C, while the ideal standard ranges from 24 °C-27 °C; (2) llighting with a value of 460.26 Lux while the ideal standard ranges from 200 to 300 Lux; (3) the illusion (noise) with a value of 80.97 dB, while the ideal standard for space theory ranges between 35-45 dB and practical space of 85 dB, and: (4) spatial design with 46.21 m2 results, while the standard ideal size for each work unit ranges from 64 m2. Keywords: ergonomic, physical environment, workshop

Abstract

Tujuan dari penelitian ini untuk untuk mengetahui apakah merdeka belajar memiliki pengaruh secara parsial dan signifikan terhadap minat belajar siswa kelas X (sepuluh)  teknik pengelasan SMK Muhammadiyah Bungoro. Penelitian ini menggunakan metode deskriptif kuantitatif. Jumlah sampel  dalam penelitian ini sebanyak 41 responden. Adapun responden dalam penelitian adalah seluruh siswa kelas X (sepuluh) teknik pengelasan SMK Muhammadiyah Bungoro. Penentuan sampel menggunakan teknik probability sampling. Teknik pengumpulan data dengan memberi kuesioner pada responden. Dalam membuktikan dan menganalisis hal tersebut, maka digunakan uji validitas dan reliabilitas, analisis deskriptif, uji asusmsi klasik, uji regresi linear sederhana, uji koefisien determinasi dan uji t. Hasil pengujian menunjukkan bahwa : 1) Variabel merdeka belajar (X) berpengaruh terhadap variabel minat belajar (Y). Hasil pengujian tersebut diperoleh dari nilai konstanta (a) variabel X sebesar 7,606 yang mengandung arti bahwa nilai konsistensi variabel merdeka belajar sebesar 7,606. Nilai koefisien regresi (b) variabel X sebesar 0,967 yang menyatakan bahwa setiap penambahan 1% nilai merdeka belajar maka minat belajar akan bertambah sebesar 0,967. 2) Secara parsial berpengaruh terhadap variabel minat belajar (Y). Hasil pengujian secara parsial menunjukkan bahwa, nilai t_tabel   dengan alpha 5% sebesar 2022 dan nilai t_hitung  sebesar 14,624 dan nilai signifikansi 0,000 < 0,05. Sehingga t_hitung > t_tabel, maka Ho ditolak dan Ha diterima,. Dengan demikian hasil uji t (parsial) adanya pengaruh positif dan signifikan dari variabel merdeka belajar (X) terhadap minat belajar.

Abstract

Misconception is well-known as barrier to students in learning science, and many studies have tried to investigate the type of misconception and try to remediate the common misconception after finding the cause of it. A study about how to provide information about an overview of the eye optics concept in physics was conducted to analysis pre-service teacher misconceptions about the eye optics and provide solutions with conceptual change text-based analogy model in learning processing qualitatively. Data were collected from Open ended question in worksheet of exploration phase (WEF) and Open-ended question in worksheet of concept application phase (WCA). The study resulted in explanation that misconceptions occur in the preservice teacher, especially in the matter of the eye optics. There are three types of Misconceptions. Firstly, They thought that: 1) many understand that the eye as is a biological study and which is the five senses in living things/human body and the rather than they do not understand the eyes as an optical instrument that can detect light and how the eye itself can see objects as a result of the light reflecting process that occurs in the eye ; 2) in determining the nature of the image formed in the eye, it was written based on the experience of seeing in everyday life, namely: real, upright, equal in size. In fact, if it is depicted using a graph using the principle of the passage of light, then the nature of the image formed on the eye is real, inverted, and reduced. ; and 3) in determining the type of lens needed for those whose eyes have problem to be able to see properly that can be used by people with eye defects does not first determine the strength of the lens but is determined based on the type of eye defect suffered. For example, near sighted people (hypermetropy) use glasses with concave lenses and people with farsightedness (myopia) use convex lenses. So that when they encounter problems in the application of concepts to determine the strength of the lens for sufferers of eye defects, both near sighted and farsighted, they tend to be wrong because they do not pay attention to the use of a negative sign (-) in the object's image distance which is calculated mathematically. They immediately determine the power of the lens by solving it mathematically and later at the end of the new solution then they are given a mark based on the type of lens used for people with eye defects.
