Abstract

Sorbitol is a sugar alcohol which has a molecular formula of C6H14O6. The production of sorbitol by the hydrogenation process is carried out at high pressure so that a large amount of energy is required. The use of considerable energy in the production process supports the need for innovation for energy efficiency in the production of sorbitol from dextrose, which is expected to help increase sorbitol production so that it can meet market needs. The innovation carried out here is to change the operating conditions with the help of Ru/ASMA@AC catalyst so that the temperature required during the reaction is low. In addition, modifying the use of heat exchanger units so that the heat generated during operation is reused. These innovations were simulated using Aspen HYSYS software. The results of the simulation proved to be able to improve energy efficiency by reducing the performance of compressors and coolers used during production and saving considerable energy.

Abstract

Program Kuliah Kerja Nyata (KKN) Tematik yang dilaksanakan di Desa Cokro bertujuan untuk mendorong potensi desa menjadi kawasan wisata berbasis kelestarian lingkungan. Desa ini memiliki kekayaan alam berupa Umbul Ingas dan aliran Sungai Pusur, yang telah dimanfaatkan sebagai objek wisata, namun masih menyimpan potensi untuk dikembangkan lebih lanjut. Pelibatan masyarakat dalam menjaga keberlanjutan kawasan tersebut menjadi hal yang krusial melalui upaya konservasi lingkungan. Salah satu pendekatan yang digunakan dalam kegiatan ini adalah edukasi mengenai pentingnya pengelolaan air bersih secara berkelanjutan serta teknologi pengolahan limbah dengan metode presentasi dan poster. Kegiatan ini juga disertai dengan usulan pemanfaatan limbah tersebut menjadi pupuk organik cair sebagai bentuk penguatan sistem pengolahan limbah. Selain itu, dirumuskan pula rancangan pengembangan wilayah wisata air baru pada bagian aliran Sungai Pusur yang belum dimanfaatkan, dengan menerapkan prinsip prinsip pengelolaan sumber daya air yang berwawasan lingkungan. Seluruh rangkaian kegiatan ini diharapkan dapat menjadi kontribusi nyata dalam mendukung Desa Cokro sebagai desa wisata yang berkelanjutan.Kata kunci : Wisata, Pengelolaan, Konservasi, Air, Limbah tahu cair
