Abstract

Analyzing the security of hosting services is important to ensure website security. This research was conducted to test thesecurity level of the Village website. By using 15 samples with 5 websites each, on each Hosting service such as Wordpress,Blogspot, and Shared Hosting. With the Black Box method and Google dork to find the target website to be tested. Open WebApplication Security Project (OWASP) Zed Attack Proxy (ZAP) to find security holes by scanning websites. The resultsobtained are usually 3 types of vulnerabilities, namely Cross Site Scripting (XSS), Cross-Site Request Forgery (CSRF)Tokens, and Clickjacking. After that, analyze the results by seeing how many warnings you get from the scanning process tofind out which hosting service has the highest level of security.This research aims to help the village government build a secure village website. By choosing a safe hosting service andknowing how to find security holes on the website that has been made, so that you can fix these security holes.Keywords : Hosting, OWASP, ZAP, XSS, CSRF.

Abstract

Indonesia is a country that has two seasons, namely the summer and the rainy season, when the rainy season arrives, the rainfall will be very high which can cause flooding. This can be overcome by technological innovation in the form of tools that can work in real-time to detect the condition of water flow in rivers so that losses due to flooding can be minimized. This tool uses a level sensor with the float magnetic level gauge method which is connected to the ESP32 microcontroller module as a sensor data controller and sends the sensor measurement data values ​​to the IoT platform. The sensor measurement results correspond to the water level in centimeters and are sent to the IoT platforms, namely Blynk and Telegram in real-time. The results of sending data to the Blynk and Telegram applications have an average error value of 1.5%.

Abstract

The use of a computerized system saves data processing time, data storage can be safer than manual storage and can reduce the human error factor. There fore the use of information systems as a data management tool must be designed according to existing needs. This is what is needed by SMP N 5 Palu because the management of existing subject values is still done manually so it has weaknesses, including recording grades, making attendance reports, and making report cards which is quite difficult to collect lesson values from each teacher so that the recording process becomes hampered and The process of selecting outstanding students which has been carried out so far by the school still has several weaknesses as a result it raises several problems, including the processing of data for selecting outstanding students which takes a long time and the possibility of human error occurring in data processing. Therefore, a web-based subject score information system was created with the feature of selecting outstanding students using the Profile Matching method. This system was developed using the Profile Matching method, which is a multi-criteria decision-making method that has very simple calculations but has good level of selectivity in determining an alternative. The results of this study are in the form of applications that can help provide information on subject values and decisions in determining students' academic achievements at the school.

Abstract

Air is the most important factor in human life. Air quality is the most supportive factor in the development of everyday living things. Temperature, Humidity and PPM (Parts Per Million) substances in the air are the parameters most often found in the environment around where we live. Every day there is and increase in pollution from motorized vehicles without us knowing how bad or good the air condition in our environment is. Therefore we need and air quality monitoring to find out how good the air condition around us is by using the MQ-135 gas sensor which is produces air quality output and using the DHT11 sensor which is output the temperature and humidity of the air around the sensor. And using an ESP8266 microcontroller based to display the output on the sensor anywhere and anytime with internet. It is hoped that this tool can be useful to determine the condition of the room good or bad so that users can improve the condition of the room where they live. It is also hoped that this tool can detect gasses leaks that occur in closed room and provide a warning to the user’s cellphone.

Abstract

Most people, especially women, are generally not educated about what ingredients are contained in a cosmetic and only rely on social media as a reference by looking at influencers who advertise a beauty product. To consult with a dermatologist also requires a lot of money, so they choose not to care about it, this causes many cases handled by dermatologists are cases that are too severe. Therefore, there is a need for awareness and education for women, especially teenagers regarding the use of illegal cosmetics, so through this research, the authors try to propose a free, expert-based platform that can be accessed in general by people from anywhere and anytime to carry out self- assessments or self-examinations. or education that makes it easier for the public to get easy and detailed information access regarding the hazardous ingredients contained in cosmetics. So in this study, we propose an educational media and expert-based assessment of the symptoms of the disease suffered in the form of developing an expert system based on the forward chaining algorithm and certainty factor, which involves a dermatologist. based on the results of testing the accuracy of 20 data samples, 18 data were appropriate and 2 data were not appropriate so that the accuracy obtained was 90%, and from user satisfaction testing it was found that 80% were satisfied with the system created and 20% were not satisfied.

Abstract

The design of a solar tracker with digital current and voltage measurements based on a microcontroller is a system that can follow the direction of the sun automatically based on the LDR sensor. The working principle of this tool is to direct the solar panels to follow the direction of the sun automatically and the current and voltage can be monitored digitally based on a data logger. The result of this design is that the solar tracker is programmed using Arduino Uno as the control center, LDR sensor for detecting sunlight as a determinant of the slope of the solar panel to the sun. To drive it, it uses two (2) power window motors which are controlled using the BTS7960 motor driver, and uses the INA219 sensor to measure the current and voltage. The output current and voltage of the solar panel is displayed on the LCD (Liquid Crystal Display) and can be monitored using the PLX-daq data logger.

Abstract

The predictive torque control (PTC) technique of electric motor drive is based on the principle that the determined optimum voltage vector will be applied to the motor in the next cycle. If a three-phase inverter is used, this inverter can only realize eight different switching states. One of the eight switching states is used as the optimum inverter switching state for the next cycle. PTC with one-step prediction cannot obtain an experimental motor speed control, because in the real-time implementation, there is a single sampling delay between input and optimal actuation due to a large number of real time calculations. The delay time problem could be solved by modifying the optimization steps by using the two-step prediction of PTC model. The experimental results show that the motor can follow the reference speed and command torque in the step response and variable speed experiments. In variable speed experiment, good speed and torque dynamics can be achieved by selecting the proportional gain value that corresponds to the motor speed
