Abstract
This study aims to measure the eligibility of a developed learning media. The media is a student worksheet (LKPD). The LKPD being developed is LKPD with a process of science skills based on the 5E Learning Cycle in acid-base material. This type of research is descriptive quantitative research using the ADDIE model. Researchers used a validation sheet as a validation instrument. The validation was carried out by three experts in chemistry education. The validation aspects that are assessed are aspects of content, presentation, language, and graphics. Based on the research results, it shows that the validity of the developed LKPD can be criticized as "very valid" in every aspect with a proportion value of 82.67% in content aspects, 86.67% in presentation aspects, 87.78% in language aspects, and 88.33% in graphic aspects. LKPD which is considered very feasible is expected to be a teaching material that can increase understanding of concepts and science process skills (SPS).

Summary
Penelitian ini memiliki tujuan untuk mengukur validitas dari suatu media pembelajaran yang dikembangkan. Berdasarkan hasil penelitian ini menunjukkan bahwa validitas dari LKPD yang dikembangkan dapat dikriteriakan “sangat valid” pada setiap aspek dengan nilai persentase 82,67% aspek isi, 86,67% aspek penyajian, 87,78% aspek Bahasa, dan 88,33% aspek kegrafisan. Teachers work so that chemistry can be used in life such as Chemistry Education Practice, 4 (1), 2021 - 41 Ahmadiyanti, Hidayah acid-base matter This is a training for students to understand nature by making observations to build knowledge and skills (Kemendikbud, 2014). Based on the 2013 Curriculum, what is to be achieved in learning is that students have scientific thinking skills which include observing, asking questions, processing information, presenting information, and concluding.The teacher should be able to determine an appropriate learning model that is able to improve learning outcomes and improve science process skills. According to Bilgin (2006) scientific process skills are the understanding of a method and procedure of scientific investigation
