Studi Deskriptif Tim Paduan Suara SD Negeri 01 Kota Bengkulu Dalam Konteks Musikalitas

The purpose of this study was to determine the musicality of the elementary school choir team 01 Bengkulu City. The research method used is descriptive qualitative method. The subject of this research was the choir team from the 01 Elementary School of Bengkulu City. The instruments used were observation and interviews. Data collection techniques using observation, interviews, and documentation. The data obtained were analyzed through the Miles, Huberman, and Saldana models, namely data collection, data condensation, data display, and data verification. The results of this study are the musicality of the choir team's performance at the State Elementary School 01 Bengkulu City is still not maximal, which is due to disciplinary aspects, inadequate performance aspects and inadequate implementation of supporting facilities for the choir team's activities, especially the absence of competent trainers music especially in the choir field

Effect of Severity Factor on the Subcritical Water and Enzymatic Hydrolysis of Coconut Husk for Reducing Sugar Production

Preventing the further degradation of monomeric or oligomeric sugar into by-product during biomass conversion is one of the challenges for fermentable sugar production. In this study, the performance of subcritical water (SCW) and enzymatic hydrolysis of coconut husk toward reducing sugar production was investigated using a severity factor (SF) approach. Furthermore, the optimal condition of SCW was optimized using response surface methodology (RSM), where the composition changes of lignocellulose and sugar yield as responses. From the results, at low SF of SCW, sugar yield escalated as increasing SF value. In the enzymatic hydrolysis process, the effect of SCW pressure is a significant factor enhancing sugar yield. A maximum total sugar yield was attained on the mild SF condition of 2.86. From this work, it was known that the SF approach is sufficient parameter to evaluate the SCW and enzymatic hydrolysis of coconut husk. Copyright © 2021 by Authors, Published by BCREC Group.
