Abstract

Abstract.  This study is a quasy experimental with pretest posttest control group design that aimed to determine the influence of guided inquiry learning on students’ motivation and learning outcome. The population of this research was all of X grade students at SMA Negeri 3 Tana Toraja in academic year 2017/2018. Sampling technic used random sampling that choosed X MIA 3 grade as experiment group and X MIA 5 grade as control group. Technic of data collecting were test and non-test method which were analysed by using anacova. The results of this study showed that students’ motivation and learning outcome who taught by implementing guided inquiry learning in high category and there is  significantly difference between students’ motivation and learning outcome who taught by implementing guided inquiry learning and direct instruction. Keywords: guided inquiry, learning motivation, learning outcome.

Abstract

Lignocellulosic biomass is an abundant and renewable carbon source with great potential for biodiesel production by oleaginous yeasts. These yeasts can accumulate high amounts of lipids when grown on lignocellulosic biomass, which primarily consists of glucose and xylose. However, the complex structure of lignocellulosic biomass requires pretreatment and hydrolysis steps to release fermentable sugars. This process often produces by-products in the form of inhibitors such as furfural, 5-hydroxymethylfurfural (HMF), and acetic acid, which can inhibit yeast growth. Therefore, oleaginous yeasts capable of simultaneously assimilating glucose and xylose and are tolerant to inhibitors, are needed to optimally utilize this substrate. This review discusses yeast species that can utilize lignocellulosic hydrolysates for growth, the types and compositions of available sugars, the mechanisms of sugar assimilation, and the impacts of inhibitors on lipid production. This review aims to provide a comprehensive understanding of the potential and challenges of using lignocellulosic biomass for biodiesel production by oleaginous yeast. Keywords: Lignocellulosic biomass, oleaginous yeast, lipid, inhibitor, biodiesel
