RESUME PERTEMUAN 1 (26/05/2023

Pada pertemuan pertama dengan pak ahmad indra siswantara(DAI) kami diberi penjelasan tentang pengantar dalam mempelajari mata kuliah metode numerik. Pak Dai menekankan bahwa kita harus berusaha semaksimal mungkin daripada kita menyontek dan tidak tau arah materi tersebut. Pak DAI memberikan arahan mengenai pentingnya kesadaran dalam menyelesaikan suatu masalah. Diberikan pula study case berupa matematika dasar dimana jawabannya adalah undefined dan infinite. 0/0 merupakan bentuk tak tentu, oleh karena itu apa yang mendasari kita mengatakan bahwa ilmu pengetahuan bersifat eksak?. Pada dasarnya segala teori yang dibuat oleh manusia tidak dapat dibuktikan kebenarannya, semuanya hanyalah pendekatan untuk mempermudah kita dalam mengkonsumsi ilmu pengetahuan. Karna pada akhirnya, kebenaran hanya milik Tuhan Yang Maha Esa. Pak DAI juga menjelaskan perbedaan mengenai ilmu pengetahuan dan ilmu agama, dimana pada dasarnya keduanya bernilai sama. Namun, perlu diingat bahwa ilmu pengetahuan adalah buatan manusia sedangkan agama berasal dari Tuhan. Kami juga diberikan Tugas untuk membuat desain tabung hidrogen dengan optimum, volum tabung 1 liter, dengan tekanan 8? desain dengan batasan harga tidak boleh lebih dari 500 ribu, Tabung hidrogen ini nantinya dipergunakan untuk mencampur dengan bahan bakar di motor agar lebih irit.
