Abstract

This study aims to develop a dynamic system model designed to improve service quality and reduce the gap between the expected and actual levels of community satisfaction. The study is motivated by the importance of understanding the interaction between key variables such as human resources (HR), information and communication technology (ICT), and evaluation mechanisms within a feedback-based service system. The system dynamics method is employed to construct causal loop and stock–flow models to simulate their impacts over a 12-month period. The simulation results show that strengthening HR, ICT, and evaluation aspects leads to a significant improvement in service quality, which directly increases community satisfaction. In addition, the gap between actual and targeted satisfaction shows a decreasing trend over time. Community feedback emerges as a crucial factor that accelerates performance improvement through reinforcing loops. Graphical and tabular representations support the positive dynamics of the main variables and demonstrate the system’s flexibility in responding to internal changes. This study demonstrates that dynamic system modeling is an effective approach to managing complex service systems. By illustrating nonlinear interactions among variables and considering time delays, decision-makers can simulate policy impacts before implementation. The study concludes that feedback-based models can serve as useful tools for simultaneously improving public services and reducing performance gaps.

Abstract

This study develops a deterministic mathematical model integrated with system dynamics to measure key success factors driving e-government maturity in Indonesia’s education sector. Addressing the gap in previous research, which mainly relied on descriptive methods, the model quantitatively examines causal relationships among leadership commitment, budget support, digital infrastructure, human capital, service quality, and feedback mechanisms. The methodology involves three stages: (1) constructing a causal loop diagram based on theoretical and empirical insights, (2) converting these relationships into a linear system of equations normalized on a [0–1] scale, and (3) performing simulations and sensitivity analyses to evaluate policy scenarios. Simulation results indicate that even relatively high leadership commitment (K=0.75) only produces moderate maturity levels (M≈0.409). The greatest improvement occurs when feedback loops are reinforced and service quality investments are prioritized. Sensitivity analysis reveals the model is particularly responsive to changes in feedback effectiveness and service quality weighting, identifying these as critical leverage points for accelerating transformation. Under optimal conditions, maturity can increase from 0.41 to 0.48, reflecting a 7% gain over the baseline. The study contributes a replicable quantitative framework for evidence-based policymaking, while noting limitations in parameter assumptions and empirical calibration for future refinement.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan kompetensi penulisan dan publikasi ilmiah masyarakat akademik menuju jurnal terakreditasi SINTA melalui model Klinik Penulisan Artikel Ilmiah. Latar belakang kegiatan ini adalah rendahnya kemampuan publikasi dosen, guru, dan peneliti muda di daerah akibat keterbatasan kompetensi teknis dan minimnya pendampingan publikasi berkelanjutan. Metode yang digunakan adalah clinic-based training berbasis daring yang mengombinasikan webinar penulisan artikel ilmiah, praktik penulisan berbasis naskah nyata, serta pendampingan teknis submission melalui sistem Open Journal System (OJS). Evaluasi dilakukan menggunakan pre-test, post-test, dan pemantauan luaran publikasi. Hasil kegiatan menunjukkan peningkatan kompetensi peserta secara signifikan, ditandai dengan seluruh peserta (100%) memperoleh skor post-test di atas batas kompetensi minimal dan berhasil melakukan submit artikel ke jurnal ilmiah nasional. Sebagian naskah telah berstatus published dan accepted, sementara lainnya masih dalam tahap review. Kegiatan ini efektif meningkatkan kapasitas publikasi ilmiah dan berpotensi direplikasi sebagai model pengabdian berbasis literasi akademik yang berkelanjutan
