Abstract

Tesis ini menyajikan pengembangan dan optimasi jaringan distribusi fluida untuk sistem tiga node dan empat node, dengan mengevaluasi secara sistematis berbagai topologi jaringan seperti star (bintang), hull, tree (pohon), mesh, ring, dan konfigurasi hybrid. Melalui simulasi berbasis MATLAB, studi ini menganalisis metrik kinerja utama seperti total panjang pipa, kehilangan energi, dan biaya ekonomi. Analisis sensitivitas juga dilakukan untuk menilai pengaruh kecepatan desain, faktor gesekan, dan perubahan posisi node. Hasil penelitian menunjukkan bahwa topologi jaringan berperan penting dalam menentukan efisiensi instalasi maupun operasional. Di antara konfigurasi yang dievaluasi, topologi star muncul sebagai solusi optimal untuk logistik suplai yang diberikan, dengan total panjang pipa terpendek dan kehilangan energi terendah, sehingga menghasilkan biaya keseluruhan yang minimal. Topologi tree terbukti paling ekonomis dari segi biaya instalasi, sementara topologi mesh dan hybrid menawarkan keunggulan dalam aspek keandalan dan kemampuan ekspansi. Optimasi diameter pipa berdasarkan kecepatan dan aliran menghasilkan penghematan energi jangka panjang yang signifikan, meskipun pilihan yang paling hemat energi tidak selalu sejalan dengan investasi awal terendah. Studi ini menekankan pentingnya pemilihan topologi dan menunjukkan nilai dari optimasi grid kasar-halus serta analisis sensitivitas distribusi node. Temuan ini memberikan panduan praktis bagi para insinyur dalam menyeimbangkan biaya, efisiensi, dan ketahanan sistem di aplikasi dunia nyata.

This thesis presents the development and optimization of fluid distribution networks for three-node and four-node systems, systematically evaluating various network topologies including star, hull, tree, mesh, ring, and hybrid configurations. Using MATLAB-based simulations, the study analyzes key performance metrics such as total pipe length, energy loss, and economic costs. Sensitivity analyses were also conducted to assess the effects of design velocity, friction factor, and node position perturbations. The results highlight that network topology plays a crucial role in determining both installation and operational efficiency. Among the evaluated configurations, the star topology emerged as the optimal solution under the given supply logistics, offering the shortest total pipe length and the lowest energy loss, thereby minimizing overall cost. Tree topology proved most economical in terms of installation, while mesh and hybrid topologies provided advantages in reliability and expandability. Optimizing pipe diameter based on velocity and flow led to significant long-term energy savings, though the most energy-efficient option did not always align with the lowest initial investment. The study emphasizes the importance of topology selection and demonstrates the value of coarse-fine grid optimization and node distribution sensitivity analysis. These insights offer practical guidance for engineers in balancing cost, efficiency, and system robustness in real-world applications.
