Abstract

Dalam teknologi penangkapan ikan yang berkembang saat ini masih menggunakan teknologi fishfinder yang berbasis akustik, selain mahal tidak semua ikan terdeteksi alat ini. Padahal Kementerian Kelautan dan Perikanan (KKP) saat ini telah menyediakan peta digital daerah persebaran ikan. Peta tersebut kita kenal dengan Peta Perkiraan Daerah Penangkapan Ikan (PPDPI). Untuk mengatasi permasalahan tersebut, sudah mulai dikembangkan teknologi yang lebih baik, yang dinamakan Portable Virtual Assistant untuk nelayan. Penelitian ini menfokuskan pada cara memperoleh data latitude dan longitude area berkumpulnya ikan yang berasal dari peta PPDPI. Terlebih dahulu gambar peta digital tersebut diolah dengan cara menentukan area fokus gambar peta yang akan diolah pada tahap berikutnya dengan menggunakan image processing. Area fokus gambar peta tersebut dirubah dari gambar berwarna menjadi hitam-putih. Dengan hitam-putih, gambar lebih mudah diolah lagi untuk ditemukan titik koordinat piksel gambar. Titik koordinat piksel tersebut dirubah ke latitude dan longitude dengan cara menggunakan rumus perbandingan latitude dan longitude peta dunia. Hasil penelitian ini mampu memberikan keakurasian hingga 1.791838% untuk latitude dan 1.11416% untuk longitude. AbstractExisting fishing technology still uses the acoustic-based fishfinder, besides expensive, itdoes not detect all types of fish. Whereas, Ministry of Marine Affairs and Fisheries Republic of Indonesia has provided digital map of fish distribution. The digital map is known as Peta Perkiraan Daerah Penangkapan Ikan (PPDPI). To tackle the problem, a better technolgy has just been developed , namely Portable Virtual Assistant for sailor. This study focuses on how to get latitude and longitude of fish group sourcing from the PPDPI map. Firstly the digital map is processed to determine the focus area of map image processed on the next steps by image processing. The focus area of map image is changed from color image to black and white image. By black and white image, it is easier to be processed again to be found coordinate-piksel of image. The coordinate-piksel was converted to latitude and longitude by comparing formula latitude and longitude of world map. The result is able to give accuracy up to 1.791838% for latitude and 1.11416% for longitude.

Abstract

AC motors are becoming increasingly popular in the industry due to their reliability and ease of control. It can be used in liquid mixing machines that require regular mixing of materials. The aim of this research is to control the speed of an AC motor using the PID method to ensure that the motor rotation remains stable when a disturbance occurs. The simulation results show that applying PID parameters with Kp of 4717, Ki of 41059, and Kd of 0.136 produces an error value of 8.75%. This is different from a system without PID, which has an error value of 15.2%, and these results show a performance increase of 6.45%. Therefore, the PID method is effective in improving the performance of PLC-based liquid stirring systems

Abstract

Maritime traffic management in major ports requires a comprehensive understanding of vessel movement patterns to ensure operational efficiency and safety. This study presents a spatio-temporal analysis of vessel traffic in Kaohsiung Port, Taiwan, utilizing a 10-month snapshot of AIS data (December 2024–October 2025). Employing quantitative methods including Kernel Density Estimation (KDE) for spatial intensity mapping, grid-based discretization for traffic density quantification, and temporal resolution analysis at multiple scales, the research identifies key operational hotspots and peak traffic periods. The analysis encompasses 1,247,890 AIS records from diverse vessel types, revealing distinct spatial clustering patterns in port entrance channels, anchorage zones, and terminal areas. Temporal analysis demonstrates pronounced diurnal and weekly cyclical patterns, with peak traffic intensities occurring during daytime operational hours and weekdays, reflecting commercial shipping schedules and port operational rhythms. The KDE-based hotspot identification reveals high-density zones concentrated within 0.5 nautical miles of major container terminals, indicating critical areas requiring enhanced traffic monitoring and collision avoidance measures. Grid-based traffic density quantification provides granular insights into vessel distribution across different port sectors, enabling zone-specific risk assessment and resource allocation strategies. The findings reveal complex spatio-temporal patterns that reflect the port's role as a major container hub in the Asia-Pacific region. Despite data quality limitations such as unspecified vessel types (59.9%) and incomplete destination fields, the results provide actionable insights for port authorities to enhance safety, optimize operations, and support strategic planning. This methodological framework demonstrates scalability and transferability to other port environments, contributing to the advancement of data-driven maritime traffic management systems
