PENDAHULUAN Pemakaian bahan bakar fosil di Indonesia yang berlebihan dan terjadi sejak dahulu telah mengakibatkan semakin langkanya persediaan bahan bakar. Adanya krisis energi dan masalah lingkungan yang ditimbulkan, maka perlu dikembangkan suatu energi alternatif yang dapat menggantikan peran bahan bakar berbasis fosil [1]. Seiring dengan perkembangan teknologi dan pesatnya pertumbuhan jumlah penduduk menuntut semakin meningkatnya kebutuhan energi. Penemuan baru di bidang energi alternatif dari biomassa semakin berkembang. Salah satu energi alternatif yang berpotensi untuk di kembangkan adalah biohidrogen [2]. Biohidrogen merupakan sumber energi yang bersih, efisien, dan dapat diperbaharui karena proses pembakaran biohidrogen di udara hanya menghasilkan uap air dan energi panas. Keunggulan dari biohidrogen adalah dapat dihasilkan dari bahan yang dapat diperbaharui, ramah lingkungan, hasil pembakaran berupa uap air yang tidakmenyebabkan efek rumah kaca, hujan asam dan merusak lapisan ozon Limbah organik yang cukup melimpah di Indonesia adalah kulit pisang. Kulit pisang merupakan bahan buangan (limbah buah pisang) yang cukup banyak jumlahnya, yaitu kira-kira 1/3 dari buah pisang yang belum dikupas. Pada umumnya kulit pisang ini belum dimanfaatkan secara nyata, hanya dibuang sebagai sampah yang dapat menimbulkan suatu permasalahan [3] [4]. Berdasarkan data produksi pisang di Indonesia terlihat pada Tabel. 1 bahwa jumlah biohidrogen dari limbah kulit pisang secara fermentasi anaerob, yang ditinjau dari segi kelayakan analisa ekonominya apakah layak untuk dikembangkan lebih jauh atau memerlukan efisiensi di beberapa tahap yang diperlukan. Berdasarkan latar belakang diatas, dilakukan penelitian lebih dalam mengenai proses produksi.

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%.

PENDAHULUAN Proses pencegahan penyebaran bakteri, jamur dan virus yang paling tepat adalah mencuci tangan dangan menggunakan sabun dan air yang mengalir. Membiasakan diri menggunakan masker atau melakukan cuci tangan menggunakan sabun atau handsanitizer setiap selesai beraktivitas [1]. Akan tetapi perkembangan sosial masyarakat modern menuntut agar aktifitas manusia untuk selalu bergerak dengan cepat dan menggunakan waktu seefisien mungkin, sehingga antiseptik sediaan gel pembersih tangan atau handsanitizer merupakan produk pilihan masyarakat karena mudah dibawa kemana-mana dan cukup tersedia di pasaran. Penggunaan handzanitizer sangat mudah dengan meneteskan atau menyemprotkan pada telapak tangan sudah cukup efektif [2]. Penggunaan bahan baku biohandzanitizer secara umum masih didominasi oleh penggunaan alkohol. Pemilihan asap cair sebagai bahan baku berangkat dari riset yang telah dilakukan sebelumnya. Diketahui komponen senyawa yang terdapat pada asap cair dari biomassa kulit jambu mente terdiri dari phenol dan turunanya, benzenediol dan turunannya, Pyroline, Alpha-D-Lyxofuranoside, heptine dan pyran [3]. Efektifitas asap cair sebagai bakterisida dan fungisida disebabkan oleh asap cair limbah biomassa memiliki kandungan senyawa yang bersifat antibakteri yaitu senyawa fenol dan asam. Fraksi fenol dan asam ini dapat menghambat pertumbuhan serangga dan bakteri [4]. Kebutuhan bahan baku alternatif yang bisa digunakan sebagai antiseptik khususnya hand sanitizer selain alkohol. Salah satu bahan yang jadi pertimbangan adalah asap cair. Secara umum asap cair adalah suatu hasil destilasi/pemisahan atau pengembunan (kondensasi) dari uap hasil pembakaran biomassa melalui proses pirolisis.

PENDAHULUAN Industri kimia mengolah bahan baku menjadi suatu produk dengan nilai ekonomi yang tinggi dalam jumlah yang besar. 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. Model tidak akan selalu bisa mewakili proses secara utuh karena proses sering terpengaruh banyak gangguan yang tidak dapat diidentifikasi. Selama ini, penelitian mensimulasikan suatu proses menggunakan aspen plus dan mengendalikan proses yang telah dibangun di aspen plus menggunakan matlab simulink secara terpisah. Sutikno dkk mensimulasikan kolom distilasi deisobutanizer di aspen plus dynamics kemudian proses tersebut dikendalikan secara terpisah menggunakan pengendali IMC di matlab simulink [2][3]. Sutikno dkk juga mensimulasikan nonkonvensional kolom/rectifier dengan menggunakan pengendali MPC [4][5]. Model proses yang diambil dari aspen plus dilinierisa si sehingga model proses belum mewakili proses yang sebenarnya. Suatu sistem dikatakan nonlinier jika prinsip superposisi tidak berlaku. Jadi, untuk sistem nonlinier respons terhadap dua input tidak dapat dihitung d","PeriodicalId":15308,"journal":{"name":"Journal of Chemical Engineering & Process Technology","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80110494","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}
