Abstract

Penelitian ini bertujuan untuk mengoptimalkan produksi etilen glikol dari limbah etilen oksida hasil proses sterilisasi menggunakan simulasi Aspen Hysys dan metode Response Surface Methodology (RSM). Etilen glikol merupakan produk kimia penting yang banyak digunakan di berbagai industri, seperti otomotif, tekstil, dan plastik. Namun, proses produksi tradisional sering kali memiliki tantangan terkait konsumsi energi yang tinggi dan pembentukan produk sampingan yang tidak diinginkan. Dalam penelitian ini, limbah etilen oksida dari proses sterilisasi diolah kembali untuk menghasilkan etilen glikol dengan pendekatan yang lebih efisien secara energi. Simulasi dilakukan menggunakan perangkat lunak Aspen Hysys untuk memodelkan berbagai skenario operasional, termasuk variasi suhu, tekanan, dan fraksi uap. Optimasi dilakukan menggunakan metode Response Surface Methodology (RSM) dengan desain eksperimen Central Composite Design (CCD) untuk mengevaluasi interaksi antar variabel. Berdasarkan hasil prediksi RSM, kondisi optimal tercapai pada suhu 196°C, tekanan 14 atm, dan fraksi uap 0,6, yang menghasilkan kemurnian produk sebesar 99,85%, penghematan energi mencapai 55,869%, dan kapasitas produksi sebesar 15.176,596 kg/jam. Hasil simulasi aktual menunjukkan sedikit perbedaan dengan hasil prediksi, di mana penghematan energi tercatat sebesar 62,09%, kapasitas produksi 14.318,3067 kg/jam, dan kemurnian produk tetap berada pada angka 99,85%. Analisis varians (ANOVA) menunjukkan bahwa suhu dan fraksi uap memiliki pengaruh yang signifikan terhadap efisiensi energi dan kapasitas produksi. Hasil penelitian ini membuktikan bahwa pendekatan kombinasi simulasi Aspen Hysys dan optimasi RSM efektif dalam meningkatkan efisiensi energi dan memaksimalkan hasil produksi etilen glikol.

Abstract

The field of materials and technology has developed rapidly, various types of inventions have been developed and researched to obtain new materials that are suitable for use at low production costs. The potential of bamboo plants is promising where the availability is abundant and sustainable, the utilization of specimens is made with polyester binders reinforced with natural and synthetic fibers. The type of bamboo that will be investigated for the tensile strength and toughness of the specimen with the difference in fiber volume fraction is a reference for the combination of bamboo fiber and fiber-glass where the volume fraction of 25% SB:25% FG, 35% SB:15% FG and 40% SB:10% FG particles at a fixed resin volume is 50%. Of the three variations in the volume fraction, the highest tensile strength in a balanced fiber filler is 40% bamboo fiber: 10% fiber-glass with an average value of 80.907 MPa, with a tensile strain of 2.53 % The lowest tensile strength value is in the volume fraction of 35% bamboo fiber: 15% fiber-glass with an average value of 75.552 MPa, with a tensile strain of 2.09%. For the highest toughness value of the specimen is in the volume fraction of 35% bamboo fiber: 15% fiber-glass, i.e., 0.83 J〖/mm〗^2 With an absorbed energy of 43.73 joules. On the other hand, the lowest toughness value is in the volume fraction of 25% bamboo fiber: 25% fiber-glass with an average value of 0.24 J〖/mm〗^2. With an absorbed energy of 39.94 joules. The observation results showed that the fiber volume was good at a percentage of 40% SB with 15% FG suitable for combination as an alternative tensile material. The toughness value in the volume fraction of 40% SB:10% FG is very low. However, the observation of bamboo fiber fracture results has a strong enough ability for the application of manufacturing products and others.
