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

This study examines about Prosthetic robotics technology which gradually continue to develop so that its use is wider. In this research author designed a control system on Microcontroller to move Prosthetic Arm. Prosthetic is an artificial device to replace the missing part of the body, this condition can occur through the condition at birth (abnormalities), illness and trauma. The purpose of this research is to create a Prosthetic Arm Prototype that can perform motion gripping, squeezing and removing. Prosthetic Arm was designed by using several control systems such as NANO Arduino, servo motor, flex sensor and Bluetooth as the main component. The Prosthetic Arm movement can only be operated based on the input of the control system that has been designed so that the movement operating on the Prosthetic Arm is desired. The result of this study shows that Prosthetic Arms can do gripping motion at 155° – 173° servo degree, squeezing motion at 180° servo degree and removing motion at 0° servo degree.

Abstract

Machining technology, especially for micro hole cutting cases is a challenge in the industrial world to supply for components that have micro dimensions. The purpose of this study was to measure dimensional accuracy (roundness) and burr formation in the part of the entrance and exit holes. The object of the material used is brass plate. Brass plates with a thickness of 0.5 mm will be drilled using a twist drill chisel 0.2 mm diameter made from tungsten carbide material. Spindle rotation speed varied is 14,000 rpm, 17,000 rpm, and 20,000 rpm. The variation in feed rate for each spindle rotation is 5 mm / min, 8 mm / min, and 10 mm / min. The hole from the results will be observed and measured using a stereo microscope. From the measurement results show that the size of the largest hole dimensions with a value of 0.217 mm is formed at a rotation of 14,000 rpm and a feed rate of 5 mm / min, while the smallest hole diameter with a value of 0.202 mm is formed at a rotation of 20,000 rpm and a feed rate of 10 mm / min. The highest entrance burr value of 0.050 mm was formed at a rotation of 17,000 rpm and a feed rate of 10 mm / min, while the lowest height of 0.038 mm occurred at a rotation of 14,000 rpm and a feed rate of 5 mm / min. The highest exit burr value of 0.077 mm was formed at a rotation of 17,000 rpm and a feed rate of 10 mm / min, while the lowest height of 0.032 mm was formed at a rotation of 14,000 rpm and a feed rate of 5 mm / min. The results of this research data conclude that the accuracy of the hole dimensions and burr formation becomes better as the spindle rotation value and machining feed rate increase.

Abstract

Penggurdian merupakan salah satu proses pemesinan yang umum digunakan pada industri manufaktur. Pada proses gurdi gaya potong sangat mempengaruhi hasil dari penggurdian tersebut. Semakin tinggi gaya potong maka semakin besar getaran dan gesekan yang terjadi sehingga dapat menyebabkan kekasaran pada benda kerja dan keausan pada pahat potong. Penelitian ini mempelajari tentang pengaruh parameter pemotongan dan metode Minimum Quantity Lubrication terhadap gaya potong pada proses gurdi. Pengukuran gaya potong menggunakan dynamometer semi konduktor sebagai alat untuk mengukur gaya tekan/gaya potong pada saat proses penggurdian berlangsung. Proses pembuatan lubang ini menggunakan dua jenis metode Minimum Quantity Lubrication yaitu dengan laju aliran 300 ml/jam dan 500 ml/jam, beberapa parameter pemotongan yaitu dengan kecepatan pemakanan (100, 120, 140) mm/min kemudian putaran spindle yang digunakan (800, 1000, 1200) rpm. Berdasarkan hasil pengujian menunjukkan bahwa gaya potong terendah diperoleh pada putaran spindel 1200 rpm dan laju pemakanan 100 mm/min dengan laju aliran 500 ml/jam didapatkan gaya potong 303,50 N, gaya potong tertinggi diperoleh pada putaran spindle 800 rpm dan laju pemakanan 140 mm/min tanpa menggunakan media pendingin didapatkan gaya potong 539,34 N.
