AbstractOil Palm Empty Fruit Bunch (OPEFB) is a type of solid waste from the palm oil processing industry. The components of OPEFB include cellulose, hemicellulose, and lignin. OPEFB has a large cellulose content, so it possesses the potential to be used as a bioplastic material. The purpose of this research was to examine the stages of the bioplastics' production process and its characterization. The cellulose content of OPEFB as raw material and during the isolation process which includes hydrolysis, delignification, pulping, and bleaching are 39.59%, 56.00%, 59.85%, 61.48%, and 68.20%, respectively. Cellulose isolation produces α-cellulose content of 97.87%. The resulting cellulose acetate has an acetyl content of 25.93%. The bioplastics were then characterized to determine the effect of cellulose acetate, starch, chitosan, and glycerol on the physical and mechanical properties of the plastics. The results of the physical properties characterization include biodegradability, water absorption, and density with values of 78.73%, 38.26%, and 1.2% respectively. The results of the mechanical properties characterization include tensile strength, elongation, and modulus of elasticity with values of 0.729 MPa, 4.13%, and 17.5 MPa, respectively. The functional groups in the bioplastics, which are O-H, C-H, C-O, C=O, and N-H, are produced from the mixing process between cellulose acetate, starch, chitosan, and glycerol.

From this combination, 100% seaweed has the highest effectiveness in decreasing 27% pH level , 75.16% turbidity, 91.43% of TSS of and 97.77% of COD level.","PeriodicalId":15308,"journal":{"name":"Journal of Chemical Engineering & Process Technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81949967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Most chemical processes are closely related to nonlinear processes so that control issues become a challenge for an engineer and the chemical industry itself. This study aims to integrate Aspen Plus Dynamics and Matlab Simulink as an effort to eliminate linearization techniques so that nonlinear processes can be controlled optimally. The method used is steady state simulation using Aspen Plus in the distillation process with a case study of the separation of propane and isobutane. Furthermore, dynamic simulation using Aspen Plus Dynamics. The process that has been built in Aspen Plus Dynamics is then integrated with Matlab Simulink through the AMSimulation block. The results of this study are that the steady-state and dynamics simulations were successfully run. Aspen Plus Dynamics Journal of Chemical Process Engineering e-ISSN Number 2655 2967 2 and Matlab Simulink are integrated and able to run together at the same time. There are three controllers installed, namely reflux drum level control, top column pressure control, and reboiler level control. The three controllers are able to control the process well, as evidenced by the process being able to return to the setpoint.

Dalam prosesnya, adanya interaksi yang kuat antar variabel proses, kondisi operasi yang berbeda – beda menyebabkan pentingnya mendesain pengendali yang handal untuk menjaga keselamatan lingkungan, memaksimalkan hasil produksi, dan meminimalkan biaya operasi. Sebagian besar proses kimia berkaitan erat dengan proses nonlinier, banyak proses fisik diwakili oleh model nonlinier sehingga masalah pengendalian menjadi tantangan bagi seorang engineer dan industri kimia itu sendiri. Banyak peneliti memilih menggunakan metode linier untuk mengatasi permasalahan pengendali nonlinier dengan cara linierisasi. Teknik linierisasi terbatas dalam mengendalikan proses kimia dengan tingkat nonlinier yang tinggi [1]. Hal yang paling umum terjadi adalah adanya ketidaksamaan antara model dengan proses yang ada.
