This research is aimed to develop the e-modul of acid base based of discovery learning.. The type of research used is research and development or Research and Development (R&D). The development model used is a 4-D model (four-D models) which consists of 4 stages, namely: define, design, develop and disseminate. This research is limited to the stage of development, namely the validity and practicality test. The research instrument used was a questionnaire of validity and practicality. The E-Module was validated by 5 validators while the practicality test was carried out by 3 chemistry teachers and 27 XI grade students of MIA SMA UNP Laboratorium UNP. Data from the validity and practicality test results were analyzed using the cohen kappa formula. Based on the results of the study, it was found that the average kappa moment of validity test was 0,953 with a very high validity category and the average kappa moment of teacher practicality was 0,921 and students were 0,883 with a very high practicality category.

The research aims at producing a valid biology module with local wisdom-based to senior high school students of Lubuklinggau. The research used research and development design with local wisdom-based. The development of the module refered to four D model which was developed by Thiagarajan. The model consists of four stages, namely Define, Design, Develop, and Disseminate. However, the research was limited on the development stage, particularly on validation stage. The validity test on this stage was a theoretic validity, which is executed by the three experts. The validation included material validation, construction/media validation, and language validation. The result showed that the development met the validity criteria with material validity score 4,165; construction/media validity score 4,259; and language validity  score 4,338 categorised to be 'very valid'. In conclusion, the biology module developed with local wisdom-based to senior high school students of Lubuklinggau was valid. Keywords: validity, biology module, local wisdom
