Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

At the end of 2019 the world faced the Covid 19 Virus pandemic which also changed activities in daily life. All activities are carried out at home (Work From Home) including meetings and exchanging information via digital. Problems at this time in the office of PT. PLN often loses internet connection, at PT. PLN ULTG Tarahan also uses 2 ISP (Internet Service Provider) lines Indihome and Icon Plus in the server room, there is no system that can regulate the two ISP networks so that they can switch connection lines if there is a disturbance on the main ISP line so that there is a possibility of interruption during activities using the internet network. Failover is a technique for adding connections in Mikrotik, where if one of the internet connections dies (main connection), the other connection (backup connection) will replace the main connection line by defining a check gateway and differentiating the distance value on each routing rule. The results of this study will be able to guarantee the availability of internet at the PT. PLN ULTG Tarahan so as to increase employee productivity.
