“…Scilab biasanya digunakan dalam pemodelan matematika di bidang teknik rekayasa, namun Scilab juga bisa digunakan dalam pembelajaran. Randjawali & Riupassa (2019) menggunakan Scilab dalam penerapan kalkulus di perguruan tinggi. Adapun Supriyadi (2020) menyimpulkan bahwa Scilab bisa digunakan untuk mengukur pemahaman siswa SMK dalam operasi matematika dasar dan dasa-dasar pemrograman komputer.…”

“…Hal ini dikarenakan karena materi matematika di sekolah menengah masih relatif sederhana dan dapat menggunakan software pembelajaran matematika lainnya yang lebih fungsional, seperti Geogebra. Adapun Scilab oleh Randjawali & Riupassa (2019) diterapkan pada materi kalkulus di perguruan tinggi. Walupun demikian, Supriyadi (2020) berhasil menggunakan Scilab ini pada siswa SMK dalam operasi matematika dasar dan dasar-dasar pemrograman komputer.…”

One of the competencies mathematics teachers need is the deepening of subject matter in mathematical concepts. Among the methods that can be done is through software training to support mathematics lessons. One of the software that can be used in learning mathematics is Scilab software. The use of Scilab software in mathematics learning cannot be separated from the role of the teacher. This service activity aims to carry out online training for Scilab software for learning mathematics. The method used is an online training and evaluation of activities by a questionnaire about knowledge and skills using Scilab software. This online training was carried out synchronously two times in the September 2020 period and was accompanied asynchronously through the Edmodo software. 68 teachers actively participate in this online training who are members of the Mathematics Subject Teachers' Consultation (MGMP) for Lebak Regency High School Mathematics and Nusantara Mathematics for Banten Region. The teacher's response to learning using the Scilab software depends on the teacher's initial ability to use the software. The result of this activity is that this online training can add insight to teachers about mathematics learning software, especially Scilab. Of the 68 participants who participated in the training, only 36 participants filled out the questionnaire. There is 8 person with excellent results, 9 people satisfied, 6 people extraordinary, 10 people enough, and 3 people low.

In this paper, we present the imaging formation process of the piecewise mirror eyes of the deep-sea spookfish, which has a strange combination of refractive and reflective eyes. The biological reflective eye structure is formulated to the curved surface’s flat mirror array. Zemax is utilized to evaluate optical features such as the modulation transfer function, distortion, and imaging performances. However, the natural images are highly distorted, and the resolution is lower than expected. Therefore, we increase the number of piecewise mirrors of the fisheye to see higher quality images, which can be improved entirely by the mirror shapes. Finally, the fisheye’s imaging analysis reveals the deep-sea creature’s resolution limit and also shows the possibility of artificial and biomimetic camera applications.
