Experiments have been successfully carried out to react with lactic acid and 1,4-butanediol, tin (II) chloride dihydrate (SnCl2.2H2O), chloroform, methanol, liquid nitrogen, nitrogen gas, and silicone oil at various concentrations. The objective exists to synthesize polylactic acid by forming polylactic acid diol (PLA-OH) via a direct polycondensation reaction of lactic acid and 1,4-butanediol in a glass reactor following a specific reaction scheme. Synthesis was carried out using different amounts of reagents according to the predetermined mole ratio of lactic acid (AL) and 1,4-butanediol (BD). The FTIR, 1H NMR, and GPC analyses that characterized the PLA-OH revealed its physicochemical characteristics. The FTIR and 1H NMR characterization results show new absorption peaks and a shift in PLA-OH absorption peaks. It indicates that a bond has been formed from the reaction between lactic acid molecules and 1,4-butanediol to produce PLA-OH. From the spectrum analysis, it can be concluded that the structure of the synthesized PLA-OH has four different proton environments (there are four different peaks in the spectrum). The peaks originate from the protons in methylene (-OCH2CH2CH2CH2O), internal methine (-O-CH-), and methine at the end of the PLA-OH chain, as well as proton peaks in methyl (H3C-). The characterization results with GPC showed that the tendency to increase Mn PLA was directly proportional to the increasing amount of lactic acid in the PLA chain

This research is motivated by the low learning outcomes of basic chemistry and the diversification of academic backgrounds of first-year students that hinder in-depth understanding of concepts. The problem focuses on testing the effect of the Project Based Learning (PjBL) model integrated with the Science, Technology, Engineering, and Mathematics (STEM) approach on student academic achievement. This quantitative study applies a quasi-experimental method using a pretest-posttest control group design in two study groups. The instrument used is an objective learning outcome test consisting of 20 validated multiple-choice questions. The results show that the average posttest score of the experimental class reached 77, while the control class only obtained a score of 61. This superiority is reinforced by the achievement of the N-gain index of the experimental group of 0.6 which exceeds the control class with an achievement of 0.4. Based on the inferential independent sample t-test using the SPSS program, a significance value of 0.000 was found to be less than 0.05, indicating a significant difference in achievement. The main conclusion of the study confirms that the application of the PjBL model with the STEM approach has proven to be much more effective in boosting student learning outcomes evenly compared to the conventional model. This interdisciplinary approach successfully facilitates students in constructing a meaningful understanding of stoichiometry through applied projects that connect mathematical calculations with real scientific phenomena in the laboratory.
