PENGARUH KADAR CAMPURAN BIOMASSA PADA CO-FIRING BATUBARA TERHADAP KARAKTERISTIK PEMBAKARAN DAN ENERGI AKTIVASI
Abstract
Studi ini mengkaji dampak proporsi campuran batok kelapa sebagai campuran dalam co-firing batu bara terhadap sifat pembakaran dan energi aktivasi. Co-firing merupakan pembakaran campuran antara batubara dan biomassa, proses ini diterapkan untuk mengurangi dampak negatif dari pembakaran batubara murni.penelitian ini bertujuan untuk mengetahui rasio campuran kadar cofiring dilihat dari proses degradasi masanya. Penelitian ini menggunkan 3 campuran batok kelapa sebesar 0%, 20%, 40%. Analisis degradasi massa menggunkan metode Thermogravimetri Analysis (TGA) dengan waktu 60 menit dan suhu hingga 1000°C dan juga kenaikan suhu sebesar 10°C/menit. Hasil hasil pengujian TGA mendapatkan data hasil berupa peluruhan massa total dengan bentuk persentase. menunjukan proses pembakaran campuran batok kelapa 0% memiliki degradasi massa yang paling kecil sebesar 95,42% lebih sedikit daripada campuran 20% sebesar 96,53% dan semakin turun pada campuran batok kelapa 40%.

Abstract
This research investigates how the ratio of coconut shell mixture used in coal co-firing affects combustion characteristics and activation energy. Co-firing involves burning a blend of coal and biomass, and this method is utilized to mitigate the harmful effects of burning coal alone. This research seeks to identify the mixture ratio of cofiring levels observed through the process of mass degradation. This research employed three blends of coconut shells at 0%, 20%, and 40%. The mass degradation analysis employs the Thermogravimetric Analysis (TGA) technique with a duration of 60 minutes, reaching temperatures up to 1000 °C, in addition to a rate of temperature increase of 10 °C per minute. The TGA test results provide data as total mass loss represented in percentages. The combustion process indicates that the 0% coconut shell mixture experiences the least mass degradation at 95.42%, which is lower than the 20% mixture at 96.53%, and also declines in the 40% coconut shell mixture.
