Abstract

This paper describes the prototype and implementation of the unmanned surface ship to detect illegal fishing using solar power generation technology. Indonesia, one of the Southeast Asian countries, has some of the world’s most productive fishing grounds. Under the leadership of President Joko Widodo, Indonesia has launched a severe crackdown on illegal fishing in its waters. The color tracking technique is the capability to take a picture, segregate a specific color, and extricate data regarding the location of that picture containing merely that color. Whilst processing the pixels in a vision, the CMUcam5 controls a counter that keeps tracking the number of consecutive pixels in the current row before being within the tracked color bounds. The current pixel is marked as a tracked pixel only when the value is higher than the noise filter value. The team has developed innovative features to complete the program. The features are double hull and propulsion design, automatic cooling system, automatic camera scanning using pixy CMUcam5 for image processing, Webcam video camera, voice command with system recognition intelligent software, fuel engine speed maximum 50 km/h, double fin, solar panel for supply battery, and computerized control. In the screen base station, we can see the situation of PTS Siluman Ship from serial communication microcontroller, serial communication image processing CMUCam 5, video webcam, GPS, and compass. All of the data from PTS Siluman Ship are sent online.

Abstract

This paper presents a new robust optimization technique for distribution network configuration, which can be regarded as a modification of the recently developed genetic algorithm. The multi-objective genetic algorithm has been applied to this problem to optimize the total cost while simultaneously minimize the power loss and maximize the voltage profile. The IEEE 69-bus distribution network is used in the tests, and test results have shown that the algorithm can determine the set of optimal nondominated solutions. It allows the utility to obtain the optimal configuration of the network to achieve the best system with the lowest cost.

Abstract

Software for accounting information systems has its own peculiarities, because the transaction data is recorded in pairs over a period of time, must be traceable and can be seen again in the future at the time period desired by the user according to the accountability of financial information systems. This research presents a prototype development technique about inter-account configuration in the accounting structure and aims to provide technical assistance on how to develop a pattern of financial transaction information presentation on a double entry record system model using financial applications. Relational data set theory and concepts are used as a scientific explanation framework on how the correlation between accounts can be constructed mathematically so that the concepts can be understood by programmers when they develop software. The result of this study has been tested by applying to the financial applications in one of the microfinance institutions and it can work properly. The prototype development techniques of this research can be applied to the software development in the business field, such as services, manufacturing and trade byimplementing in the form of the software configuration system tools. furthermore, the financial application developers are expected to utilize this prototype development technique to produce more dynamic software as a financial data processor according to the accounting rules in the business organizations.

Abstract

At this time controlling electrical equipment in the form of fans and lights are still mostly using conventional switches. By using an android voice command device with a bluetooth connection, controlling the equipment can be easier. Using a Bluetooth connection will reduce the use of cables and speed up the process of activating or deactivating electronic devices because they do not have to get close to reach the switch. With input in the form of voice commands is very easy in controlling electronic devices such as fans and lights. With the adjustment of the fan speed and brightness of the lights with voice commands can save electricity and more easily in its settings

Abstract

Analysis of the performance of the LTE network with WiFi networks was carried out in the G5 building of the Faculty of Engineering, University of Muhammadiyah Yogyakarta, which is the building of the Faculty of Engineering Laboratory. This research was conducted by comparing the LTE network with indoor or indoor WiFi networks, measuring these two networks using the Network Analyzer and Wifi Analyzer application to obtain information on signal quality data based on KPI and TIPHON standardization, which shows RSRP, RSRQ, and Throughput values through measurement using the Network Analyzer and Wifi Analyzer application. From the results of research that has been done shows that the G5 building has a WiFi internet network that is superior to the LTE internet network. The overall condition of the Wifi network is in very good condition and is stable for each floor. While the LTE network even though it has increased conditions on the second floor but overall is in a bad condition to normal. The LTE network has an RSRP value with an average of -143 dBm, while a WiFi network with an average of -90 dBm. Then the LTE network has an RSRQ value with an average of -13 dBm, while the Wifi network with an average of -15 dBm. For LTE network throughput it has an average max. ping by 50.9 ms and min. ping is 864.5 ms, while WiFi networks have max average. ping by 24.3 ms and min. ping of 144.5 ms. From the results of these data show that the G5 Building has a good WiFi network and is superior to the LTE network.

Abstract

With the increasing number of people contaminated with cat disease, many veterinarians specializing in cats in Indonesia open up a practice in big cities only. Thus, it is not uncommon for cat owners who are late to provide treatment for skin diseases since the initial symptoms occur. Based on the problems to overcome skin diseases in cats, it is necessary to build a computerized system that has knowledge such as veterinarians and the system can be a tool in diagnosing types of diseases and provide solutions for treatment and prevention with the expert system of Certainty Factor (CF), because the Certainty Factor (CF) method is to prove whether a fact is certain or uncertain in the form of a metric that is usually used in expert systems. The results of the system are to help users, among others, veterinarians in diagnosing skin diseases in cats and animal owners, especially cats to find skin diseases in cats. It is expected to make it easier for doctors and cat owners to determine the type of skin disease based on existing symptoms and get the right treatment method.

Abstract

One way to prevent the transmission and spread of Covid-19 is to always keep ourselves and our environment clean. Maintaining personal and environmental hygiene can be done by using antiseptics and disinfectants. Disinfectants that are not used properly will be bad for humans. That is why so far the spraying of disinfectants for the prevention of COVID-19 has been carried out by human workers who are dressed in complete Personal Protective Equipment (PPE) using manual sprayers. This is certainly very risky to humans who do the spraying manually. The objective of this research is to minimize the risk of spraying disinfectants, by using a robotic power to spray disinfectant based on the Internet of Things (IoT) and a camera. This robot is operated by using a smartphone while to determine the environmental conditions around it is used a camera. From the test results, it obtained data that the robot works well and is quite reliable due to the wider scope limit because it uses an IoT connection to communicate with smartphones. The results of camera readings on laptops are also quite clear, although the higher the resolution on the display, the lag time required to transfer images to the laptop affects.
