Abstract

With the development of means of communication and the exchange of information over the Internet, and with the development of hacking operations, intruders became able to view, and change information, so the need to find means to preserve privacy and information exchange arose. Cryptography and steganography had a prominent role in this field Encryption distorts the message and steganography hides the message's presence. In this paper, the proposed system uses both steganography and cryptography to provide a double layer of security. In cryptography, we use both a substitution and RSA algorithm to encrypt the message. In steganography, we used LSB technology with a stego key to embed data in the image, all of this to improve data security. A scale of Mean Square Error (MSE) and a scale of peak signal-to-noise ratio (PSNR) assessed system performance. The results showed that the image quality is good, and it is difficult to notice any difference between it and the original image. The results of both MSE and PSNR were good, as the PSNR value was more than 56.

Abstract

The development of the shipping industry in Indonesia has continued to increase over the past 10 years due to the sabotage principle. This development can be seen from the increasing number of national vessels. The number of national vessels becomes wider from 6,041 units in 2005 to 24,046 units in 2016. The number of vessels makes monitoring the operational performance of the vessel difficult because each ship has different travel routes. This research made tools that can monitor the performance of ships especially the use of MFO aboard the ship. The sensors used to measure the volume of MFO in the tank on board are HC-SR04 ultrasonic sensors and potentiometer pendulum sensors. The data from the sensor was processed by Arduino Uno microcontroller. This study would compare the performance of ultrasonic sensors and potentiometer pendulum sensors mounted on MFO oil premises. The study was conducted by measuring the position of the ship horizontally, right and left tilted with a slope level of 30 degrees and 45 degrees. The result of this research is that the potentiometer pendulum sensor was better when MFO surface condition was flat with the average of error sensor 1.60%, while HC-SR04 ultrasonic sensor has an average of error for 2.87%. However, on the skewed surface conditions of MFO, the usage of HC - SR04 ultrasonic sensors was better with average of error for 3.21%, while the potentiometer pendulum sensor had an average of error for 8.66%.

Abstract

Measurement of the remaining MFO oil in the tank when the ship is sailing makes the crew become more troublesome because it must be reported within a certain period of time, for example every once an hour using a pendulum sensor. The measurement using this pendulum sensor the accuracy and precision of each becomes a deficiency of the value produced because the position of the ship is not taken into account. Another disadvantage of conventional methods is that fraud can occur if the tank capacity is full by manually falsifying measurement data, then MFO can be sold in the middle of the sea to fishermen or smuggled illegally to an outside country. To overcome these problems, the need for special monitoring for the availability of MFO oil in tanks by ship-owners needs to be carried out. In this case the accuracy, precision and the need for data that is always displayed and known by ship-owners is very important for the business management process of the company. For that, a precise, accurate and real-time fuel consumption monitoring tool is needed. As a comparison, manual measurement of appeal sensors was also carried out in order to get a more significant comparison value. There are 4 HC-SR04 ultrasonic sensors needed to get accuracy and precision on the position of the ship such as horizontal, tilted to the right, tilted to the left with a slope of 8 degrees and 16 degrees. The test results have shown that the four HC-SR04 sensors are able to read more accurate than the pendulum sensors in various ship positions. The reading result with HC-SR04 sensor has an error below 5% compared to an error in the pendulum sensor of 7.5%. Then, the mean error on the surface of the tank with the condition of a flat vessel of 2, 08%, on the position of the tilted vessel of 2.17% and the condition of the ship with a bumpy wave of 3.35%. The results of the measurement of the MFO volume in the tank sent through the internet to the monitoring station can be perfectly received so that it becomes accurate and real-time information for the observation of fuel consumption by the company management. Thus the prototype of monitoring the use of MFO fuel on passenger ships can be used to replace conventional measurement models which use pendulum sensors.

Abstract

LPG is an alternative fuel that is used for daily needs, it is caused not only because of its cheap price but also its easy installation. However, the characteristic of LPG gas which is flammable and heavier than oxygen makes LPG gas leakage is hard to be detected. Based on that problem, a system that is able to detect gas leakage is needed and the system itself has to pass the sensitivity level test to be gas sensor. In this study there are 3 sensors; MQ-2, MQ-5 and MQ-6 gas sensors which are connected to the Arduino Uno microcontroller as it can be used as a feature to classify the condition of the gas by the implementation of the Fuzzy Mamdani method. The output of the system is displayed on an LCD, marked with a buzzer and a fan as gas decoder. The Arduino Uno that was programmed using fuzzy logic was used to control the level of leakage and to give a solution level through the rotation of fan and the buzzer sound. From the test results, the system could determine various conditions of gas leakage with 93% accuracy. From the results of its simulation and test, MQ-5 had higher sensitivity rather than MQ-2 which had the lowest sensitivity toward gas leakage.   Keyword: Leakage, LPG Gas, Fuzzy Logic,

Abstract

The wind turbine generator used for charging the battery produces an unstable electrical voltage, this is caused by the wind speed on the highway that varies. As a result of the instability of the electrical voltage, the energy storage charging process is not optimal. To deal with these problems, voltage stabilization is carried out using a boost buck converter to maximize the use of electrical energy generated from the wind turbine generator. This study discusses about a prototype voltage stabilizer for battery charging using a boost buck converter circuit. Implemented a comparison of two different techniques, including the application of fuzzy Mamdani logic control with PID using Ziegler-Nichols to minimize the value of settling time, percentage of overshoot, steady state error, and maximum voltage ripple. The results show that application of fuzzy Mamdani logic control is more effective than the application of PID using Ziegler-Nichols. In the study, it was found that the effectiveness of adding a charging circuit protection system and monitoring system did not exist in previous studies.

Abstract

Within this paper, we will discuss about a development process of SpO2 monitoring system that will be used for detecting a patient in the early stage of stroke. This system will measure and compare the SpO2 from both right and left arm at the same time. Stroke patients who experience weakness in the muscles of the one hand can experience different values with hands that do not experience muscle weakness. Stroke patients who are hospitalized with an intravenous infusion in one arm can cause differences in SpO2 values between the right and left fingers. Therefore this measurement method held from that phenomenon. From the monitoring system design, the system should have two sensors to measure the blood saturation, a microcontroller to process the data, and a monitor, buzzer, and micro sd card module to store and display the data. The research shows that the system has been developed and can be used to measure patient’s SpO2 from both hands at the same time, an indicator that will rings when there is an error in the measurement, and a lcd display to show the measurement data. This system also has a microSD card writer to store the measurement data from time to time.
