Tujuan penelitian ini adalah untuk mengembangkan bahan ajar berupa LKPD berbasis Guided Inquiry pada mata pelajaran ekonomi kelas X IPS SMA yang dikembangkan dengan model pengembangan R & D dengan metode 4-D (define, design, develop dan Disseminate) dengan desain uji coba yang digunakan adalah pretest-posttest control group desain yang diujicobakan terbatas pada 20 peserta didik di SMA Negeri 1 Sumberrejo
Hasil validasi para ahli menunjukkan kelayakan komponen isi sebesar 89,35%, komponen evaluasi sebesar 77,77%, dan komponen grafis 77,14% diperoleh rata-rata keseluruhan sebesar 81,42% yang dikategorikan sangat layak. Efektivitas LKPD dilihat dari ketuntasan klasikal peserta didik pada kelas ekperimen sebesar 90% dengan gain score sebesar 0,80 kategori tinggi sedangkan kelas kontrol ketuntaasan klasikal sebesar 40% dengan gain score 0,64 dalam kategori sedang serta respon peserta didik sebesar 97,5% dalam kategori sangat baik. Sehingga dapat disimpulkan bahwa pengembangan LKPD berbasis guided inquiry pada mata pelajaran ekonomi kelas X IPS SMA layak digunakan dalam pembelajaran ekonomi.

The purpose of this study was to develop teaching materials consisting of Guided Request-Based student worksheet on social studies class X high school economics subjects developed with the 4-D method of R & D development (defining, designing, developing and disseminating) with the trial design used the pretest-posttest control group design which was tested was limited to 20 students in SMA 1 Sumberrejo
The results of the expert validation showed component feasibility of 89.35%, the valuation component was 77.77%, and the graphic component 77.14% obtained an overall average of 81.42% which was categorized as very feasible. The effectiveness of student worksheet is seen from the classical completeness of students in the experimental class by 90% with a gain score of 0.80 in the category of classical mastery control class of 40% with a score of 0.64 in the medium category and the response of students at 97.5% in very good category. So that it can be denied that the development of inquiry-based student worksheet on economic subjects in class X IPS SMA is feasible to be used in economic learning.
