Abstract

The aim of this study was to know the effect of dosage variation  brotowali stems extract (Trinospora crispa L.) on the mortality of aphid (Aphis gossypii L.) cucumber (Cucumis sativus L.). The most effective dose for mortality of aphid, and to design of biology learning resources of high school class x even semester in the form of Student Practicum Worksheet (LKPS) . Based on the kruskal wallis test that has been done and shows reject H0 that there is an effect if the result X2 count 1273.99> X2 table 19.7 at α 0.05 in the Chi-square table, thus H0 is rejected, and H1 is accepted that there is an influence of variation dose of brotowali (Trinospora crispa L) stem solution to the mortality of aphids (Aphis gossypii L.) cucumber (Cucumis sativus L). The results showed that the most effective dose of brotowali stem extract could result in at 20% dose. At dose of 20%  there are many compounds from the brotowali stems that can maximize the mortality of aphid pests. The results of the feasibility test learning resources by the validator design and content validators material get good results to be used as a source of biology learning.
