Abstract

Acetone is an essential ingredient in various industries whose demand continues to increase, thus requiring an efficient production method. This study aims to design an acetone production process by dehydrogenating isopropyl alcohol using Aspen HYSYS simulation and Aspen Energy Analyzer energy analysis. The simulation model was developed to enhance the purity of acetone products and improve energy efficiency by optimizing thermodynamic operating conditions. The dehydrogenation process was designed to produce acetone as the main product and hydrogen as a by-product. The basic process was then modified by integrating thermal energy and increasing the reactor operating temperature to improve energy efficiency and product purity. Simulations showed that the process modification resulted in an acetone purity of 99.76%, higher than the base process of 98.46%. In addition, energy savings in the modified process reached 40.89%, higher than the base process of 32.96%, with a reduction in carbon emissions of up to 40.88%. With these results, the modified process proved more efficient than the basic process and aligned with the research objectives.

Abstract

Proses pengolahan kotoran hewan (kohe) kambing menuai kendala, antara lain, pada aspek homogenitas material, yang diakibatkan karena ukuran partikel yang tidak seragam dan adanya pengotor. Penelitian ini bertujuan untuk mengkaji pemanfaatan paralon dan ember bekas untuk menyaring dan menghomogenkan kohe kambing sebagai bahan untuk membuat pupuk organik. Metode penelitian ini meliputi desain dan konstruksi alat dari bahan bekas, proses penyaringan untuk memisahkan kotoran dari material kasar, dan penghomogenan untuk memperkecil ukuran partikel. Evaluasi dilakukan secara kualitatif dengan pengamatan keseragaman tekstur dan kemudahan proses pemadatan (komposting) lebih lanjut. Hasil penelitian menunjukkan alat (saringan dan penghomogen) bekas memudahkan untuk mengolah kohe kambing yang lebih homogen, dan mengurangi waktu untuk pengolahan lebih lanjut pupuk organik. Selain itu, penggunaan bahan bekas pada alat saring dan homogen ini menjadikan alat ramah lingkungan, berbiaya murah, dan mudah direplikasi oleh masyarakat. Dengan demikian, inovasi sederhana ini berpotensi sebagai alat teknologi tepat guna untuk pengelolaan dan peningkatan kualitas pupuk organik secara komunitas.
