Abstract

One of the technology that can be utilized to meet the energy demands is biomass combustion. In this study, the biomass sources is from part of the palm oil such as empty fruit bunches, palm oil fiber, palm oil fronds, and palm oil shell. This research was conducted using a fluidized bed combustor (FBC) tool, which aims to observe the characteristics of the combustion process on FBC devices. The characteristics observed in this study were the combustion temperature profile, flue gas composition, and the composition of the ash deposit chemical compound. The results obtained from this study are the best combustion temperature profile which is in the condition of combustion of 2 kg biomass with 1,25 m /minute velocity of air and the maximum combustion temperature obtained in the condition of combustion with a mass of 3 kg biomass with 1,25 m 3 /minute velocity of air. The best combustion conditions occur when the ammount of biomass is 3 kg and with 1,25 m 3 /minute velocity of air with the least amount of O2 and the highest amount of CO2 respectively 0.2 % and 19.9 %. The highest combustion efficiency in the FBC device is when burning 1 kg of biomass with 0,625 m 3 /minute velocity of air in the 4th minute which is equal to 94.9%. 3

Abstract

Waste Pb are waste derived from human activities. One way to reduce this problem by adsorption through bentonite. In this research bentonite used originated from Blang Karing, Aceh. The bentonite is activated into sodium bentonite and is enlarged with Al to become Al-Pillared bentonite. Variation of metal concentration used are 300, 400, 500, and 600 ppm mixed with bentonite. Afterwards the mixture was filtered and the filtrate was taken to analyze the remaining metal content with AAS. This study showed that the greater the amount of adsorbate concentration used, the absorption of bentonite will also be greater. The amount of metal Pb and Cd left behind with initial concentration of 300 ppm respectively is 299,624 ppm (99.87%) and 289,813 ppm (96.60%). In the usage of adsorbate concentration of 600 ppm the amount of metal Pb and Cd left behind respectively is 599,605 ppm (99.93%) and 588,464 ppm (98.08%). 2+ and Cd 2+

Abstract

Industri kimia merupakan susunan berbagai unit peralatan yang terintegrasi satu sama lain secara sistematik yang dijalankan dengan sistem pengendalian tertentu. Saat ini, dikarenakan adanya isu interaksi antar loop dalam proses tuning sistem pengendalian yang berakibat pada ketidakstabilan proses telah memacu banyaknya pengkajian tentang kasus pengendali PI ataupun PID dengan sistem multivariable (MIMO) dan multiloop. Dalam penelitian ini telah dibandingkan metode tuning yang sering digunakan, yakni Biggest Log-Modulus Tuning (BLT) dengan Direct Synthesis (DS). Studi perbandingan ini dilakukan secara simulasi untuk sistem pengendali kolom distilasi. Hasil yang diperoleh menunjukkan bahwa metode  DS lebih baik dari pada metode BLT karena settling time yang lebih cepat dicapai dan nilai Integral Absolute of Error (IAE) yang lebih kecil. Hasil Fine tuning menunjukkan kinerja pengendali menjadi lebih baik dimana nilai osilasi dapat ditekan. Oleh karena itu, dimungkinkan untuk mendapatkan metode tuning yang lebih baik dari kedua metode diatas.
