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

In this research, experimental study is conducted related to the latent heat transfer and thermal energy storage using finned tubes. An experimental unit consisted of data acquisition, the heat exchanger shell and tube were used to improve heat transfer. The fluid heat pipe was designed in longitudinal fin and radial fin. Paraffin wax was used as a thermal storage medium. The characteristics of heat transfer from fluid to paraffin wax is investigated in different heat flux conditions. The experimental results show that the heat transfer characteristics show similarities to the heat exchanger tubes. In the preheating process, it is dominated by conduction, but at the melting temperature of the heat transfer, it is dominated by convection. The use of longitudinal finned pipe has been able to increase the heat transfer rate.

Abstract

The aim of this thesis is to analysis the effect of using of guide vane in order to increase turbine rotation and power. This thesis is consisting of two stages. First stage is testing the turbine without guide vane and second stage is testing the turbine with guide vane. Testing was did at Gampong Juli Keude Dua, Kecamatan Juli Kabupaten Bireuen.The test did on three kind discharge, 0,14 m3/s, 0,12 m3/s, and 0,10 m3/s by using three kind of guide vanes diameter, 25 cm, 27 cm, and 29 cm. Based on experemental result, the best efficency is 80,9 %, given from the 29 cm guide vane diameter and turbine rotation on 610 rpm with discharge  0,14 m3/s.
