Abstract

Improper processing of soymilk, such as soybean raw materials, use of well water, and use of cooking vessels, produces soymilk that does not meet SNI standards. These conditions can contaminate soymilk with harmful metals. The purpose of this study was to measure the nutritional quality and metal content of soymilk produced using aluminum and stainless steel cooking vessels. The research was descriptive and was conducted in July 2022. Analytical tests were carried out by comparing the nutritional content in the form of total protein, fat, lactose, and solid non-fat (SNF), and analyzing the heavy metal content. The results showed that the contents of Pb, Cu, and Hg in soy milk processed with stainless steel were lower than those of aluminum, from 11,494 ppm to 2,706 ppm, 114,612 ppm to 10,211 ppm, and 0,372 ppm to 0,012 ppm, respectively.  The contents of Zn and As in soymilk with stainless steel were higher than those treated with aluminum, from 884,585 ppm to 73,616 ppm and from 0,107 ppm to 0,079 ppm, respectively. Cooking water also contributed 0,055; 0,044; 0,028, and 0,156 ppm to the heavy metal content of Pb, Cu, Zn, Hg, and As, respectively. In conclusion, the use of stainless steel in soymilk processing resulted in better nutritional quality and lower heavy metal content compared to aluminum.

Abstract

Teknologi mengalami perkembangan tiap tahunnya, dimana teknologi merupakan suatu sarana yang digunakan manusia untuk memenuhi kebutuhan mereka. Banyak teknologi yang dikembangkan sehingga lebih membantu manusia untuk memenuhi kebutuhannya. Salah satunya adalah teknologi computer, yang mana di dalam computer terdapat mikrokontroller yang berfungsi sebagai pengontrol berbagai komponen elektronika di dalamnya. Pada penelitian ini membahas mengenai 30 (tiga puluh) jenis model kit mikrokontroller yang berbasis arduino UNO. Arduino UNO itu sendiri merupakan salah satu mikrokontroller atau pengendali mikro papan tunggal yang bersifat sumber terbuka dan menjadi salah satu proyek yang sangat popular di bidangnya. Tujuan dari penelitian ini akan diaplikasikan pada praktikum otomasi dan pengendalian automatic di Laboratorium Teknologi Rekayasa Pangan. Selain itu penelitian ini diaplikasikan untuk meningkatkan manajemen pengeloloaan laboratorium seperti pemasangan smoke detector, setting suhu penyimpanan alat, dan lain-lain. Penulis juga membuat video pembelajaran dan buku yang mencakup 30 (tiga puluh) jenis model kit berbasis Arduino UNO, sehingga dapat mempermudah mahasiswa dan juga pembaca untuk memahami dan mengaplikasikan model kit tersebut.
