Potential benefit for production management of a pulp and paper company from using an ft-nir analyzer

The pulp and paper segment has been seeking to increase mill efficiency through cost reduction and better production management. One of the ways to achieve this goal is through better control and operation of the pulp plant digester cooking. The study aimed to verify the accuracy of the FT-NIR analyzer in the liquor lines of a pulp and paper digester and its possible benefits for production management. The research methodology used was the case study, where it was analyzed and compared the results of the equipment with the values of the company's laboratory. The analysis of the instrument proved accurate and reliable, providing information on various properties of liquors that enable the optimization of production management with the stabilization of the operation. Future trends indicate that infrared technology will continue to play an important role as a detection platform due to its inherent flexibility and capability.

PENENTUAN EFISIENSI DYE SENSITIZED SOLAR CELL (DSSC) MENGGUNAKAN EKSTRAK BUAH KAKTUS (Opuntia elatior Mill.)

Dye-Sensitized Solar Cells (DSSC) research by using cactus fruit extract (Opuntia elatior Mill.) has been done. The objectives of the research are to determine the highest efficiency of submersion time and Dye pH treatments of cactus fruit extract (Opuntia elatior Mill.). This research was used a Complete Random Design (CRD) method whereas the submersion time of the worked electrode on five extents of treatments are 6,12,18, 24, 30 hours and Dye pH on four extents of treatments are 1, 3, 5, and 7. The result showed that the optimum time at 12 hours with the Dye pH at 3 has resulted in the highest efficiency of 0.105. Keywords: Cactus fruit extract, Opuntia elatior Mill, efficiency, DSSC.
