Authors: Mohamad Fatkhurohman  , Robingun Suyud El Syam
Published: March 2024

Agama dan sains merupakan kekuatan yang mampu mentransformasi kehidupan manusia. Harmonisasi diantara keduanya berusaha mengarahkan dan memberikan kesejahteraan bagi umat manusia. Namun, karena ketidaktahuan atau kemalasan seingkali manusia menganggap ada dikotomi antara keduanya, padahal keduanya terkait kehidupan sehari-hari. Tujuan penelitian ini untuk mengungkap relasi sains dan agama: materi besaran dan satuan dalam meningkatkan keimanan peserta didik. Melalui penelitian kualitatif korelasi, menyimpulkan: Dalam fisika, besaran diartikan sebagai sesuatu yang dapat diukur dan dinyatakan dengan angka. Sebuah besaran dinyatakan dengan angka diikuti dengan satuan. Angka tanpa diikuti satuan akan menjadi sesuatu yang tidak bermakna. Idealnya sebuah alat ukur memiliki akurasi, presisi dan sensitivitas yang baik sehingga tingkat kesalahannya relatif kecil dan data yang dihasilkan akan akurat. Ukuran adalah sesuatu yang sangat mendasar dalam bidang apapun. Ukuran erat kaitannya dengan takaran, dan dosis  yang sesuai dengan maksud firman Allah Swt dalam surat Al Qamar (54): 49, yang esensinya Apa yang terjadi pada semua makhluk sudah ditetapkan oleh Allah. Segala sesuatu menurut ukuran, yaitu suatu sistem dan ketentuan yang telah ditetapkan, tetapi manusia wajib berusaha, ketentuan-Nya diserahkan kepada usaha manusia. Dengan memahami konsepsi ini peserta didik akan bertambah nilai keimanannya.

. Currently, the times are increasingly advanced, starting from technology, transportation, payments, placement of funds in securities is one of them. Placement of funds in securities is a bank that only acts as a liaison between customers who need funds and customers who have funds. Placement of these funds is only in securities that are not listed on the stock exchange, such as BI certificates. The purpose of this study is to examine the determination of a fund to become securities and also how is the legal relationship between depositors of funds and banks and what are the legal consequences of placing funds in securities as security for wealth. The conclusion of this study is that the role of securities in a bank is inseparable from the role of banks which have a strategic function in implementing national development. The development of the times is also a supporting factor for using securities for payment, deposit of funds, investments, and others. This strategic role is mainly due to the main function of the bank as a vehicle that can collect and distribute public funds effectively and efficiently and anticipate economic and banking developments. To anticipate economic and banking developments as mentioned above, it is necessary to have laws and regulations regarding securities in general that are more adequate as an umbrella that underlies these developments.
