Abstract

This study aims to determine the effect of pretreatment on hemicellulose, cellulose, and lignin content of Salacca midrib. Unlike previous studies, this study was designed to evaluate the effects of single-, double-, and triple-stage pretreatments on the sallaca midrib. The study was also designed to evaluate the differences in the physical and biological pretreatment methods. The pretreatments applied consist of physical, chemical, biological, physicochemical, chemical-biological, physical-biological, and physicochemical-biological pretreatments. Physical pretreatment is carried out in an autoclave at 121 °C, chemical pretreatment using Sodium Hydroxide (NaOH) 4%, and biological pretreatment using Debaryomyces hansenii. Based on the ANOVA test, the various pretreatment methods have a significant effect on lignocellulose content. The highest hemicellulose content was the chemical pretreatment at 34.13%, the cellulose content was the chemical pretreatment at 40.85%, and the highest lignin reduction was the physical-chemical-biological at 27.15%

Abstract

The training and mentoring of microorganism isolation and identification practicums wereconducted as an effort to provide learning integration experiences with practicum activitiesdue to the limited laboratory facilities in high schools in Toba Regency. The community serviceactivities began with an evaluation of initial understanding related to the community serviceactivities carried out, followed by the provision of basic theory on microorganism isolation andidentification. After that continued with practical activities of isolation and identification ofmicroorganisms carried out through aseptic techniques and mentoring in observations, datarecording, and analysis of practical observation results. The activity was concluded with a finalevaluation of the activity. Training and mentoring were carried out intensively so the studentsand teachers were able to carry out the stages and analysis of practical activities appropriately.The evaluation results showed that this activity increased the understanding of students andteachers of the basic theory and practical work of isolating and identifying microorganisms for66%. This training activity is also expected to be a strategic step to encourage high schools inToba Regency to have laboratory facilities to support the integration of learning materials withpractical activities.
