INTRODUCTION
Experiment of the organic chemistry 1 is an experiment carried out to identify organic compounds studied in the organic chemistry course. The organic chemistry course is one of the compulsory courses included in the group of scientific and skill courses in the department of chemistry education at a public university in Tulungagung, Indonesia. The organic chemistry course examines the concepts, structure, nomenclature, physical and chemical properties, and reaction mechanisms of organic compounds including: hydrocarbons, alkyl halides, alcohols, ethers, aldehydes, ketones, carboxylic acids, and esters (Smith, 2011;Wade, 2013;Solomons, et al., 2014).
The implementation of experiment requires modules as experiment guides. Modules are teaching materials containing materials, methods, and evaluations that are arranged systematically as a means of independent learning (Triyono, 2021). Experiment modules can be developed in the form of e-modules (electronic modules) to support learning in the new normal era of the Covid-19 pandemic and preparing for the digital era of industrial revolution 4.0. E-module is a module that is packaged in digital form and displayed using a computer or smartphone or through the internet network which in its presentation can be equipped with audio and video. social groups as a form of local wisdom or culture (Sumarni, 2018). Ethnoscience-based learning raises local wisdom or culture that is integrated in the learning process. Shidiq (2016) stated that ethnoscience-based learning that does not separate science and local wisdom can make students understand and apply the science they learn to be used in everyday life and solve problems in everyday life so as to make science learning more meaningful.
The success of ethnoscience-based chemistry learning is shown by several research results. Shidiq (2016) showed that ethnoscience-based chemistry learning can increase student interest and achievement. Arfianawati, Sudarmin, and Sumarni (2016) showed that the application of ethnoscience-based chemistry learning can improve students' cognitive abilities and critical thinking. Trianah (2020) showed that ethnoscience-based chemistry learning is more effective than conventional learning in terms of science process skills and increased mastery of students' chemical materials.
Based on the results of these researches, the development of ethnoscience-based organic chemistry experiment e-module needs to be carried out to create experiment activities to be more meaningful and interesting. One of the local wisdom found in the area around a public university in Tulungagung, Indonesia which is related to learn in organic chemistry 1 is the production of cane brown sugar traditionally. Most of the residents around a public university in Tulungagung, Indonesia and throughout Tulungagung regency produce brown sugar from sugar cane traditionally as a hereditary activity. The results of research by Rifa'i, et al. (2019) showed that the number of residential-scale or individual-scale cane brown sugar industries in Tulungagung Regency as a whole reaches more than 300 industries. The production process of cane brown sugar traditionally can be integrated in organic chemistry 1 experiment to identify the content of organic compounds in cane brown sugar, such as aldehydes, ketones, and carboxylic acids, as well as alcohol compounds in cane brown sugar production waste.
Observation of the production process of cane brown sugar can also be used to solve many problems related to the analysis of experiment results.
The development of ethnoscience-based modules as a guide for chemistry experiment has never been carried out. A development research that has been carried out is to develop ethnoscience-based modules for learning chemical theories. Lia, Udaibah, and Mulyatun (2016) have developed an ethnoscience-oriented chemistry learning module by raising the culture of Pekalongan batik and showing that the module that has been developed is effectively used in learning by improving student learning outcomes after following the learning stages contained in the module. Utari, Andayani, and Savalas (2020) have developed an ethnoscience-based chemistry module by elevating the habits of salt farmers and demonstrating that ethnosciencebased chemistry modules meet the feasibility and practicality requirements for use in learning. environmental conservation attitudes in MAN 2 Central Lombok schools and showed that students' responses to chemistry modules with an ethnoscience approach are included in good criteria and the module can be used to instill students' environmental conservation attitudes. Nurhayati, Andayani, and Hakim (2021) have developed a STEM-based chemistry e-module with an ethnoscience approach and showed that the e-module is included in the feasible and practical category of use in learning. Based on the description of the problem, the purpose of this study is to develop and determine the feasibility of an ethnoscience-based organic chemistry experiment e-module: a cane brown sugar production process in Tulungagung< Indonesia. Furthermore, the percentage score is matched with the feasibility criteria referenced from Arikunto (2006) in Table 1.
