<![CDATA[BUMDes Sarimarta di Desa Wonosari, Kabupaten Demak, menghadapi kendala tata kelola administrasi dan pencatatan keuangan akibat penggunaan sistem manual berbasis kertas yang rawan kesalahan angka serta memperlambat penyusunan laporan pertanggungjawaban. Kegiatan pengabdian masyarakat ini bertujuan merancang Sistem Informasi BUMDes berbasis web (https://sarimarta.id) sekaligus meningkatkan kapasitas teknis pemuda Karang Taruna sebagai operator sistem. Metode pelaksanaan mengombinasikan rekayasa perangkat lunak System Development Life Cycle (SDLC) model Waterfall dengan pendekatan pendampingan Participatory Action Research (PAR). Evaluasi program dilakukan melalui perhitungan efisiensi waktu pemrosesan data serta pengukuran kuantitatif pre-test dan post-test terhadap peserta. Hasil implementasi menunjukkan bahwa penggunaan aplikasi sarimarta.id memotong durasi pemrosesan data keuangan dari 2.400 menit menjadi 120 menit, atau mencapai tingkat efisiensi sebesar 95%. Pendampingan PAR juga berhasil meningkatkan rata-rata skor kompetensi teknis anggota Karang Taruna dari 30% pada pre-test menjadi 89,5% pada post-test. Implementasi sistem digital ini mempercepat penyusunan laporan keuangan BUMDes yang akuntabel dan mendorong keterbukaan informasi publik bagi warga desa. A BUMDes Sarimarta in Wonosari Village, Demak Regency, faced administrative and financial record-keeping challenges due to paper-based manual systems, which led to data recording errors and delayed financial reporting. This community service program aimed to develop a web-based BUMDes Information System (https://sarimarta.id) and build the technical capacity of local youth from Karang Taruna as system operators. The methodology integrated the Waterfall System Development Life Cycle (SDLC) software engineering model with a Participatory Action Research (PAR) mentoring approach. Program evaluation was conducted by calculating data processing efficiency and measuring participants' technical competencies through pre-test and post-test assessments. The implementation results showed that the sarimarta.id platform reduced financial data processing time from 2,400 minutes to 120 minutes, achieving an efficiency rate of 95%. Furthermore, PAR-based mentoring increased the average technical competence score of Karang Taruna members from 30% in the pre-test to 89.5% in the post-test. This digitalization accelerates accountable financial reporting and supports public information transparency for the village community.]]>
