Penelitian ini bertujuan mengembangkan E-LKPD materi barisan dan deret berbasis etnomatematika pada Candi Jawi yang valid, praktis, dan efektif untuk mendukung keterampilan berpikir kritis peserta didik. Penelitian menggunakan metode Research and Development dengan model ADDIE yang meliputi tahap Analysis, Design, Development, Implementation, dan Evaluation. Penelitian dilaksanakan di SMK Darul Ulum Purwodadi dengan subjek 23 peserta didik kelas X Desain Komunikasi Visual (DKV) pada uji coba luas, setelah uji coba terbatas terhadap 6 peserta didik kelas X Kuliner (K). Validasi produk melibatkan ahli materi, ahli media, dan ahli pembelajaran, sedangkan kepraktisan diukur melalui respons guru dan peserta didik. Keefektifan dianalisis berdasarkan pretest, posttest, uji Wilcoxon Signed-Rank, dan N-Gain. Hasil penelitian menunjukkan bahwa E-LKPD memperoleh validasi ahli materi sebesar 96,74% (sangat valid), ahli media 86,90% (sangat valid), dan ahli pembelajaran 76,19% (valid). Kepraktisan berdasarkan respons guru sebesar 91,67% dan peserta didik sebesar 89,81%, keduanya berkategori sangat praktis. Rata-rata nilai meningkat dari 57,74 menjadi 89,81, dengan hasil uji Wilcoxon menunjukkan perbedaan signifikan (p < 0,05) dan N-Gain sebesar 0,71 berkategori tinggi. Dengan demikian, E-LKPD layak digunakan untuk mendukung pembelajaran barisan dan deret serta pengembangan keterampilan berpikir kritis melalui konteks budaya lokal Candi Jawi.
