Improving quadcopter control systems poses significant challenges in unmanned flight technology development. Key issues include the intricate nature of PID and Kalman filter parameter settings, necessitating profound knowledge of system dynamics and sensor properties. Furthermore, successfully integrating the Kalman Filter with PID control demands meticulous coordination to optimize state estimation precision and system responsiveness. This research emphasizes the incorporation of the Kalman filter into PID-based control for quadcopter pitch angle regulation. The Proportional-Integral-Derivative (PID) approach governs pitch angle, augmented by the Kalman Filter, to enhance estimation accuracy and mitigate sensor uncertainty. Optimal outcomes during system response testing were achieved with parameters of Kp at 2.95, Ki at 0.23, and Kd at 0.02, resulting in superior oscillatory response, including a 9-degree overshoot, a 5-second rise time, a 15-second settling time, and a 0.15-degree steady-state error, showcasing effective regulation of the quadcopter pitch angle. A concurrent observation during testing indicated that including the Kalman filter led to a significantly reduced overshoot compared to tests without it; conversely, the settling time experienced considerable acceleration, while measurement accuracy in the steady-state condition improved by 50%.

Penelitian ini bertujuan untuk mengembangkan sistem perencanaan jalur (path planning) robot mobile dengan menggunakan algoritma A* berbasis pengolahan citra dari kamera top-view di lingkungan simulasi V-REP (CoppeliaSim). Metode yang digunakan melibatkan deteksi posisi robot, tujuan, dan rintangan melalui segmentasi warna pada citra RGB, kemudian mengubah hasil deteksi menjadi representasi grid navigasi biner. Jalur optimal dari posisi awal ke tujuan dihitung menggunakan algoritma A*, dan hasil lintasan divisualisasikan langsung di atas peta citra asli. Pengujian dilakukan dengan variasi bobot heuristik untuk mengevaluasi pengaruhnya terhadap jumlah node yang dikunjungi dan panjang lintasan. Hasil menunjukkan bahwa semakin besar bobot heuristik, semakin sedikit node yang dieksplorasi oleh algoritma, meskipun panjang lintasan cenderung sedikit meningkat. Visualisasi berupa heatmap node yang dikunjungi dan grafik perbandingan performa mendukung kesimpulan tersebut. Sistem ini menunjukkan potensi pendekatan navigasi visual yang sederhana namun efektif, dan dapat menjadi dasar untuk implementasi lebih lanjut pada sistem robot fisik berbasis kamera. Pendekatan ini juga cocok untuk pembelajaran dan penelitian karena fleksibel, bebas sensor fisik, dan mudah dimodifikasi di lingkungan simulasi.

Comparative Advantage Analysis and Products Mapping of Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam Export Products Jayadi, Akhmad; Aziz, Harry Azhar

Publisher : Universitas Airlangga

The research aims to answer some questions. First, what kind of export product groups that the six countries have comparative advantage? Second, is there a shifting on its comparative advantage? Third, what is the relationship between six countries? Data used in this study is secondary data which published by the World Integrated Solution (WITS) of World Bank, from 1997 to 2014. Analytical tools applied are products mapping using Revealed Symmetric Comparative Advantage (RSCA) and Trade Balance Index (TBI). The results of this study showed as follows: first, on average, the comparative advantage of six countries increase. Second, Thailand and Vietnam's comparative advantage and trade balance changes seems more dynamic than those of other four countries. Third, there is competition and complementary amongst six countries.Keywords: Comparative Advantage, Export Specialization, Products Mapping, Flying Geese JEL: P51, P33

This study examines FDI influence on economic growth in 24 emerging market economies. The generalized Method of Moment (GMM) method is used in this research using panel data to see the effect of FDI on economic growth. This study also uses the Panel Vector Error Correction Model (PVECM) method to see the short-term relationship and Fully Modified Ordinary Least Square (FMOLS) to see the long-term relationship. This study finds strong empirical evidence indicating that the influence of FDI on economic growth is statistically significant in the short and long term. These results vary if we include the level of development reached by countries in emerging market economies. In upper-middle and lower-middle-income countries, FDI positively and greatly influences economic growth. Different results occur in high-income countries, and the results are positive and insignificant. The results show that FDI in high-income countries tends to leave these countries.

Map of Export Product Competition of Indonesia, Malaysia, Singapore, and Thailand Jayadi, Akhmad; Aziz, Harry Azhar

This research attempts to investigate the export product competitiveness of Indonesia, Malaysia, Singapore, and Thailand which are classified into five major groups: primer product, natural research-intensive product, unskilled labor-intensive product, technology-intensive product, and human capital-intensive product. The method used in this research is product mapping, which is the combination between Revealed Symmetric Comparative Advantage (RSCA) and Trade Balance Index (TBI). The result shows that Indonesia has a comparative advantage in the export specialization of primary products, natural research-intensive products, and unskilled labor-intensive products. Singapore and Malaysia have a comparative advantage in technology-intensive products, while Thailand has a human capital-intensive product. This research proves the flying geese pattern of the five groups of products, that if a country becomes a leader of one product, it will become a follower in another product.

Indonesia is a maritime country that has huge potential in fisheries sector. The average of indonesian fisheries production and export volumes always increase every year. This study aims to analyze the effect of exchange rates, government spending, inflation, interest rates, and sanitation policies to Indonesia fishery export to the United States in 1989-2019. Data were obtained from the Indonesian Ministry of Finance, the World Bank, UN COMTRADE, and the Indonesian Ministry of Maritime Affairs and Fisheries. This study uses the Error Coerrection Model (ECM) method to examine the effect of the independent variables on the dependent variable in the long term and short term. This study explains that in the long-term, government spending and exchange rate have positive effect, and interest rates have negative effect on export. In short-term, government spending and exchange rate have positive effect on export. Inflation and sanitation policy do not affect export in the long-term or short-term, while interest rates in the short-term do not affect Indonesian fishery exports. Keywords: Exports, Government Spending, Exchange Rates, Non-Tariff Barriers, Error Correction Model. JEL: F10, F13, C32

This study examines the effect of information and communication technology infrastructure on foreign direct investment in 20 emerging market economies. In the 90s, developing countries had policies to make it easier for investors. Emerging markets countries are significant and potential markets. There is data that emerging market countries have increased from 35.90% to contributing 46.62% of FDI of the world's total in 2019. Using 25 years of data (1995-2019), use the panel data regression method to see the influence of ICT infrastructure on FDI. Find strong empirical evidence showing that the influence of ICT infrastructure on FDI is significantly positive in emerging market economies. In addition, we also examine the relationship between the variables GDP, inflation, and Trade openness to FDI. GDP, and Trade openness have significant positive results for FDI, while inflation has significant negative results for FDI in emerging market economies.
