Abstract

A bachelor's degree in chemical engineering enhances one's capacity to adapt both hard and soft skills in the classroom and at work to the quick changes in technology and increasing competitiveness in the professional world. This motivates an individual who has graduated from chemical engineering to enhance the caliber of their work. Technology for simulation programming is one of the hard skills he needs to possess. In the realm of chemical engineering, these abilities encompass not only using Microsoft Office but also making objects work with other software. Through theoretical research on cases in the process industry, the simulation program is used. Prioritizing the operational foundation of an application is essential for work in the chemical sector. It is recommended that a graduate of chemical engineering possess software capabilities in order to facilitate their employment in the workforce. Basic requirements and increased proficiency can be supported by theoretical and data processing techniques. This article discusses the need for software skills in the field of chemical engineering, such as Aspen HYSYS, Matlab, AutoCAD P&ID, and Scilab, using a literature study methodology. This endeavor is a method of looking through library data for pertinent articles and then delving deeper into an article's content. The purpose of this article review is to balance hard and soft skills in order to determine how software is used in the field of chemical engineering and what is required in the chemical industry.

Abstract

Industri pembuatan tahu menghasilkan limbah cair pada proses produksinya. Limbah cair industri tahu mengandung zat organik tinggi serta padatan tersuspensi yang dapat berdampak negatif terhadap lingkungan dan masyarakat jika tidak dikelola dengan baik. Salah satu solusi untuk mengatasi pencemaran tersebut yaitu mengolah air limbah secara efektif dan efisien dengan sistem constructed wetland menggunakan metode fitoremediasi. Fitoremediasi dilakukan menggunakan tumbuhan melati air (Echinodorus palaefolius) dengan variasi waktu tinggal selama 3, 5, dan 7 hari. Hasil menunjukkan bahwa semakin lama waktu tinggal akan berpengaruh pada besarnya penurunan kadar polutan, pH dan suhu air limbah cair industri tahu. Pada parameter Biochemical Oxygen Demand (BOD) menunjukkan penurunan signifikan kadar polutan pada hari ke-3, 5, dan 7 sebesar 188 mg/L, 175 mg/L, dan 140 mg/L. Sedangkan untuk parameter Chemical Oxygen Demand (COD) pada hari ke-3, 5, dan 7 adalah 4.762 mg/L, 4.206 mg/L, dan 3.950 mg/L. Lalu untuk parameter Total Suspended Solids (TSS) pada hari ke-3, 5, dan 7 yaitu 376 mg/L, 178 mg/L, dan 144 mg/L. Efisiensi penyisihan kadar polutan tertinggi terjadi pada hari ke-7 dengan parameter BOD mencapai 30,35%; COD sebesar 65,26%; dan TSS sebanyak 75,59%. Kata kunci : limbah tahu, constructed wetland, melati air, BOD, COD, TSS
