Abstract

This study focuses on evaluating the thermal efficiency and exhaust emissions produced by the rotary kiln used in Factory 2 PT. Semen Baturaja Tbk. As a central component in the cement production process, rotary kiln performance has a significant impact on factory operations and the surrounding environment. This study combines direct measurement of exhaust emissions with analysis of kiln operational data to identify achieved levels of thermal efficiency and the impact of exhaust gases on the environment. The results of this study are expected to provide an in-depth view of the rotary kiln performance in terms of thermal efficiency and exhaust emissions. By understanding the factors that affect efficiency and emissions, manufacturers can design appropriate remedial measures to increase thermal efficiency and reduce environmental impact. The positive results of this research can contribute to sustainable practices in the cement industry, by ensuring that the production process is not only energy efficient but also environmentally friendly

Abstract

Ketergantungan dunia terhadap energi fosil telah menimbulkan berbagai permasalahan serius, seperti krisis energi, polusi, dan perubahan iklim. Untuk mengatasi masalah ini, transisi menuju energi baru dan terbarukan menjadi semakin mendesak. Indonesia, sebagai negara penghasil minyak sawit terbesar di dunia, memiliki potensi besar untuk mengembangkan green diesel sebagai alternatif bahan bakar fosil. Green diesel, yang dihasilkan dari minyak sawit melalui proses hidrogenasi, memiliki kualitas yang setara dengan solar konvensional dan lebih ramah lingkungan. Dengan mengembangkan green diesel, Indonesia tidak hanya dapat mengurangi ketergantungan pada impor bahan bakar fosil, tetapi juga berkontribusi dalam upaya global untuk mengatasi perubahan iklim. Green diesel diproduksi dengan mereaksikan molekul hidrogen pada molekul trigliserida, yang merupakan komponen utama dalam minyak nabati dan dibantu dengan katalis untuk mempercepat reaksi. Pada penelitian ini didapatkan, Hasil uji menunjukkan bahwa sampel biohidrokarbon memiliki densitas 780,8 kg/m, viskositas kinematik 2,24 cSt, titik nyala 64C, cetane number 75,1, nilai kalor 42,91 MJ/kg, dan berwarna kuning jernih. Semua parameter ini sesuai dengan standar EN 15940 untuk bahan bakar diesel. Cetane number yang tinggi mengindikasikan potensi pembakaran yang baik dan emisi yang rendah, sedangkan nilai kalor yang cukup tinggi menjamin ketersediaan energi yang memadai. Densitas dan viskositas yang sesuai memastikan aliran bahan bakar yang baik dalam sistem bahan bakar kendaraan. Titik nyala yang tinggi menjamin keamanan dalam penanganan danpenyimpanan.
