Abstract

This paper discusses the stability, control and observation of the dynamic system of the Lapan Surveillance UAV 05-NG (LSU 05-NG) aircraft equation. This analysis is important to determine the performance of aircraft when carrying out missions such as photography, surveillance, observation and as a scientific platform to test communication based on satellite. Before analyzing the dynamic system, first arranged equations of motion of the plane which includes the force equation, moment equation and kinematics equation. The equation of motion of the aircraft obtained by the equation of motion of the longitudinal and lateral directional dimensions. Each of these equations of motion will be linearized to obtain state space conditions. In this state space, A, B and C is linear matrices will be obtained in the time domain. The results of the analysis of matrices A, B and C show that the dynamic system in the LSU 05-NG motion equation is a stable system on the longitudinal dimension but on the lateral dimension directional on the unstable spiral mode. As for the analysis of the control of both the longitudinal and lateral directional dimensions, the results show that the system is controlled.

Abstract

This research focuses on calculating the force distribution on the wings of the LSU 05-NG aircraft by several numerical methods. Analysis of the force distribution on the wing is important because the wing has a very important role in producing sufficient lift for the aircraft. The numerical methods used to calculate the lift force distribution on the wings are Computational Flow Dynamics (CFD), Lifting Line Theory, Vortex Lattice Method and 3D Panel Method. The numerical methods used will be compared with each other to determine the accuracy and time required to calculate wing lift distribution. Because CFDs produce more accurate estimates, CFD is used as the main comparison for the other three numerical methods. Based on calculations performed, 3D Panel Method has an accuracy that is close to CFD with a shorter time. 3D Panel Method requires 400 while CFD 1210 seconds with results that are not much different. While LLT and VLM have poor accuracy, however, shorter time is needed. Therefore to analyze the distribution of lift force on the wing it is enough to use the 3D Panel Method due to accurate results and shorter computing time.

Abstract

Strategi desain signage merupakan bagian krusial dalam sistem komunikasi visual yang berfungsi untuk mempermudah orientasi, mendukung efisiensi pergerakan, serta memperkuat citra dan identitas visual suatu kawasan. Dalam konteks ini, Sekolah Vokasi IPB dipilih sebagai objek studi karena mewakili tipologi kawasan terintegrasi dengan struktur spasial multizona, yang mencakup area akademik, zona bisnis, ekowisata, dan fasilitas pendukung lainnya dalam satu kawasan kampus. Kompleksitas ini menuntut kehadiran signage informatif yang menyampaikan arah, lokasi, dan identitas dengan cara yang mudah dipahami oleh berbagai pengguna. Tujuanpenelitian ini adalah merumuskan strategi desain signage di Sekolah Vokasi IPB yang mampu mempermudah orientasi, meningkatkan efisiensi pergerakan, serta memperkuat identitas visual kawasan.Metode penelitian ini menggunakan pendekatan deskriptif-kualitatif dengan analisis deduktif berbasis teori persepsi visual untuk menafsirkan elemen signage dan merumuskannya menjadi strategi desain yang komunikatif dan kontekstual. Dari hasil penelitian diperoleh hasil desain signage informatif melalui lokasi, dimensi, material, warna, simbol/ikonografi, dan tipografi. Dengan demikian dapat dihasilkan desain yang komunikatif, fungsional, dan kontekstual.
