Abstract

The maze solving robot is the development of the line follower robot. Where the robot can trace a path that has an intersection, in tracing a maze, apart from finding a way out / finish, it will be more efficient if the robot can find a shorter path through the maze. From the maze samples made, the robot can explore a maze and find the shortest path. When the mapping process is carried out, the robot traces 12 path codes; after the path simplification process is carried out, the robot can shorten the path it takes to 6.

Abstract

This research aims to develop the Blended Learning application because of the COVID19 pandemic that is hitting the world. The application is built in such a way as to simplify the process of use in school learning by using the Research and Development (R&B) type of research. The development method used a model designed by Plomp with three stages of research: 1) Preliminary Research, 2) Prototype Phase, 3) Assessment Phase. The determination of the validity and practicality of the Blended Learning application is based on the validation test of experts and users, namely teachers and students, through a questionnaire, in determining the sample, using a purposive sampling technique. The results showed that the results of this development research were as follows: 1) The validity of the Blended Learning application was valid; 2) The practicality of the Blended Learning application based on user responses, namely teachers and students, was stated to be very practical. Based on the findings of this study, it is concluded that the Blended Learning application is very valid and very practical.

Abstract

In its development, image processing is very helpful for solving problems faced by humans. Imaging processing is an image processing technique of an object to distinguish the background and the object to be analyzed. This research uses a segmentation method that can distinguish between objects and backgrounds. Analyzing objects from ultrasound images requires the expertise of an experienced doctor. In addition, there are artificial factors that make automated analysis complicated. We aim to improve natural imagery. Therefore to overcome the potential difficulties in analysis, we present four Comparison of Edge Detection, namely Gradient Image, Roberts Operator, Sobel Operator and Prewitt Operator. In image processing, data accuracy and accuracy are required as well as knowledge of statistics because image processing is related to data processing. The result of this research is to determine which edge detection is more appropriate for analyzing ultrasound images. The conclusion from this research is that from the four operators that were tried, the results of the testing process showed that the Prewit operator succeeded in detecting existing objects, even objects that function as background were successfully detected. The resulting edge detection is smoother compared to other operators.

Abstract

Soybeans (Glycine max (L.) Merill.) are an important source of protein in Indonesia, it is a part of variety of beans. The soybeans’ need is increasing as people demand for raw materials. While there are so many problems with soy plants that they cause the decline in soy production. The decline in the production of soybean plants has been due to both pest and disease factors. Therefore in this condition it would require an expert to address the problem of soy farmers, but in this condition the lack of an expert and the time of the expert is a problem, so with by existence expert system can provide an alternative to addressing problems. This system of experts can be used to help soy farmers in an effort to identify pests and crop diseases and how the prevention and treatment of pest and soy diseases. The system was used Backward Chaining methods. This application made based Web used PHP programming language.

Abstract

INA TEWS (Indonesian Tsunami Early Warning System) is an important part of the national disaster mitigation system, and a domestic technological innovation for tsunami disaster mitigation. In the assessment of technology development priorities, INA TEWS uses the Analytical Hierarchy Process (AHP) method and the Technology Readiness Level (TRL) method to assess the level of technology readiness. There are four criteria of assesment, namely urgency of need, financing, supply of raw materials, and acceleration of innovation. INA TEWS technology is divided into four technology components, namely Technoware, Humanware, Infoware, Orgaware. Based on the preferences of expert respondents, it shows that the most prioritized criteria at this time are supply of raw materials (30.9%), urgency of need (28.4%), financing (22%) and the last is innovation creation (18.8%). For the highest priority technology components are Technoware (42.5%), Orgaware (28.4%), Humanware (19%), and finally Infoware (10.1%). Technoware components are priority and top. As seen from the test results of various sensitivity chart analysts, the Infoware component looks the lowest of all other technology components. It seems that Infoware has not become the focus of attention for management in developing INA TEWS. For this reason, the Infoware component is encouraged to immediately meet the aspect of innovation creation criteria.

Abstract

Monitoring the security of the house is something that needs to be done to prevent criminals. Housing is a very important thing for us to be aware of, where most of the perpetrators of crime occurred in homes that were left traveling by the occupants. Therefore, for the sake of comfort when we travel, monitoring the state of the house is very necessary. In this monitoring system is done by monitoring the doors and windows of the house using a magnetic switch sensor, later each sensor on the door and window will be connected to the Raspberry Pi which is synchronized with firebase, and every door or window that is open the sensor will send information to Firebase. and then by utilizing push notification firebase will send notification messages to the android application that has been designed. With this, residents monitor the state of the house when traveling using an android application that has been designed via a smartphone, where every open door and window will be visible on the android application display. Using this monitoring system can create a sense of comfort and safety for residents when traveling.

Abstract

The eye is one of the most valuable gifts of the creator. Besides being used for looking, senses of vision are also very influential in various human activities. It takes a healthy eye to avoid being disturb. One of them is an eye disease, and we often forget to treat it well because of less public knowledge to prevent eye diseases. That's why it’s needed an expert system for diagnosing and classify diseases eye of humans, which play a role in replacing and imitate the reasoning process of an expert in solving a problem. And can give the right and fast solution to be able to help an expert to diagnosing diseases stored in the database system. In this research, an expert system was built based on Android Mobile with the use of programming language Android Studio. This application exerts system uses the forward chaining method, aims to trace the symptoms that appear in the form of questions to diagnose the type of disease that can recognize the type of disease after consulting with answering questions displayed, known disease data adjusted the rules made to match the symptoms of eye disease and gave a percentage value and can conclude the type of eye disease suffered by patients to know the value of the approach type of the patient's illness.
