Abstract

Degradasi gliserol menjadi produk akrolein, menjadi salah satu topik penelitian yang menarik untuk dibahas mengingat kebutuhan dan permintaan akrolein yang cukup tinggi di Indonesia. Gliserol adalah bahan kimia penting yang murah dan mudah didapatkan di Indonesia, sementara akrolein merupakan salah satu senyawa kimia yang dapat dihasilkan dari proses pengolahan gliserol. Indonesia saat ini masih tergantung dari Impor akrolein, pada tahun 2008 akrolein yang masuk ke Indonesia sekitar 6.500 ton (BPS). Kebutuhan akrolein pada tahun 2020 disinyalir akan mencapai 10.800 ton. Nilai tersebut mengindikasikan bahwa akrolein masih dibutuhkan dalam jumlah yang besar. Berbagai macam proses yang selama ini digunakan untuk mendegradasi gliserol menjadi menjadi senyawa kimia yang lain masih dikategorikan sebagai proses yang membutuhkan waktu yang lama serta suhu dan tekanan yang tinggi, sehingga diperlukan metode alternatif guna mengantisipasi kekurangan dari berbagai macam proses tersebut (hidrogenolisis, hidrotermal dan lain-lain). Metode yang dimaksud adalah penggunaan gelombang suara atau yang lebih dikenal dengan nama metode sonifikasi. Proses sonifikasi dilakukan dengan viriabel suhu 30 – 60 oC, dengan waktu sonikasi 20 – 40 menit, dimana katalis yang digunakan adalah asam sulfat konsentrasi rendah (1%) dengan rasio massa gliserol : air adalah 1 bagian gliserol berbanding 8 bagian air. Hasil yang diperoleh pada penelitian ini adalah konversi tertinggi sebesar 48,98 % yang dihasilkan pada waktu reaksi 40 menit dengan suhu reaksi 60 oC. Pada kondisi tersebut juga dihasilkan yield akrolein tertinggi sebesar 11,45 %.

Abstract

The development of the era where everything is instantaneous and fast as it is today must be supported by the development of increasingly sophisticated information technology. One of the functions of this technological development is to obtain accurate and fast information. But in fact, there are still companies / organizations that have not used computer technology as a work aid, such as the Bromo Rajawali Convection which still uses the manual method of writing employee data, namely data storage still using books. Therefore, the design of an employee data management information system is carried out that can help companies control the production data of each tailor employee. The method used in this research is the Waterfall method. It is called a waterfall because the steps that are passed must wait for the completion of the previous stage and run sequentially, for example the design stage must wait for the completion of the previous stage, namely the requirements stage [1]. The Waterfall method consists of 5 stages, namely Analysis, Design, Coding, Testing and Maintenance. The purpose of this study is to design an information system that can make it easier for companies to write down employee production data accurately. From the design results, there are two factors that support the running of the system, namely administration and production data, the input form available on the system that has been designed, namely the login input form and the employee data input form, while the output form contains complete data related to employee personal data and employee production data. With the creation of a management information system in writing data on employee production, the Rajawali Bromo Convection can accelerate the search for more accurate data in the future, and applications made later by the company can be used properly as one of the employee production data systems
