Abstract

Aceh marine area has many potential resources that need to be explored, studied, and conserved. These activities require a suitable mean that has capability to bring data collection and observation tools into the seabed. One of the means that can carry out these jobs is the AUV (Autonomous Underwater Vehicle). AUV has an ability to dive without any supporting cables from the surface. It can be programmed to do the required task in the seabed. One of the most important parts on the AUV is the thruster system, a component that provides the thrust force. A thruster is a mechatronic device consists of power source (battery), motor controller, electric motor, and propeller as the main thrust component. A defect in the thruster design will result in the failure of the AUV thus the design of thruster is critical in an AUV unit. In this research, an experiment apparatus was design and fabricated in order to measure the performance of a thruster. The measurement includes the thrust force, the power consumption, and the total effective working time. The proposed experiment apparatus is expected to assist the design stage of the AUV before fabrication in order to minimize the failure caused by defect in the thruster system.

Abstract

 Supplies of fossil fuels as an energy source that is depleting became its own challenges in the provision of energy to the continuation of the future. One alternative is to become energy electrical energy. Study conducted in this study is meant to make the eco-friendly vehicles, one example is the electric car. Light vehicle weight and becomes a keyword in doing energy saving in everyday. The research was carried out using the element method to the frame of the car, with condition of load static – general. The software used in this study is ABAQUS. From the results stress result maximum stress of 1.972 x 105 Pa, maximum strain results of 2.592 x 10-6, while the displacement that occurred was of 2.858 x 10-7 m. Research results obtained that the car frame able to withstand loads given of 700 N, so that, it can be concluded that the framework of this car is secure against a given load.

Abstract

Marine observation and research activities require a suitable transportation means that has an ability to bring necessary equipment for data collection and observation into the sea. One of the means that has the ability is AUV (Autonomous Underwater Vehicle), an electric powered underwater vehicle. The vehicle does not require cable connection from the surface and has an ability to move to global positions according to programmable trajectory installed in a microcontroller and other navigation equipment. The control system of the AUV trajectory is programmed in the microcontroller. The navigation equipment consists of integrated sensor. The main sensor used is global positioning sensor, digital compass, pressure sensor, and 3-axys gyroscopes. The main focus of this paper is the design and application of the control system for an underwater survey vehicle that has an ability to bring necessary equipment for observation of coastal area. The vehicle moves from an observation point to another according to GPS assisted programmed data. The control system consists of the thruster system, the depth control system, the positioning system and compass system. The design and algorithm for the control system is proposed.

Abstract

Indonesian ocean has a riches of maritime ​​fishery potency, so fishery mapping is important to be maintained, examined and explored. Fishery potency observation requires a vehicle to bring the observations and data collection equipments to the seabed by  an electric-powered underwater vehicle or AUV (Autonomous Underwater Vehicle). AUV is a kind of underwater vehicle that has an ability to bring underwater observation’s instrument. The operation of these vehicles is wireless and autonomous. It is able to move to specific locations in accordance with trajectory in the programmable microcontroller and the GPS sensors. The aim this research is to design a control system for underwater survey that can make a communication  to control center on the beach by sending and receiving SMS thru GSM network. This AUV communication systems to explore coastal area, moving from one point of observation to the next observation point (point to point) in accordance with the latitude and longitude  that is programmed and customized using GIS MapQuest software, and also trajectory correction control system by using GPS. In this paper, we described control systems and data communication for navigating auv based on GPS, GSM and GIS technology. Development control systems includes trajectory monitoring system, long range control by GSM network and position tracking by GIS .

Abstract

Abstrak—Pembangkit energi listrik pada umumnya masih menggunakan bahan bakar fosil sebagai bahan bakar utamanya, sekarang ini banyak penelitian yang ditujukan untuk mencari solusi supaya mengurangi penggunaan bahan bakar fosil.  Energi ramah lingkungan yang tersedia di alam kebanyakan mempunyai karakteristik tenaga yang tidak selalu konstan. Pembangkit energi ramah lingkungan yang bisa memanfaatkan tenaga alam yang tersedia secara maksimal menjadi fokus utama para peneliti, untuk itu pada penelitian kali ini akan dibahas mengenai perancangan generator linier magnet permanen. Pada prinsipnya generator linier bekerja dengan mengubah tenaga mekanik menjadi energi listrik sebagaimana generator pada umumnya, namun terletak perbedaan pada arah gerak rotornya, pada generator umumnya rotor bergerak dengan berputar pada inti stator. Namun pada generator linier, translator bergerak maju mundur pada inti stator (gerakan lurus). Pada saat perancangan magnet akan disimulasikan kerapatan fluxnya menggunakan software Finite Element Magnetic Method (FEMM 4.2). Adapun parameter yang akan di analisa dari hasil perancangan yaitu tegangan yang dihasilkan, frekuensi serta kecepatan linier generator. Dari hasil simulasi menunjukkan dengan kecepatan linier 1 m/s pada translator. Hasil pengujian generator linier magnet permanen Emax tiap fasa yaitu R=8.2V, S=8.2V, T=8.3V. Serta hasil perhitungan Emax tiap fasa yaitu R=8.0V, S=8.5V, T=8.5V. Perbandingan Emax hasil perhitungan dan pengujian tanpa beban terdapat perbedaaan rata-rata sebesar 2.33%, dengan tingkat keakuratan pengujian yaitu 97.7%. Hasil yang diharapkan dari penelitian ini yaitu didapatkannya sebuah generator linier yang dapat di aplikasikan pada sumber energi kinetik dari alam dengan rpm rendah.  Kata kuci: pembangkit, FEMM, generator linier, fluks magnetik, simulasi, energi kinetik.
