Abstract

To clean the floor, it can be done manually by using a floor mop along with floor cleaning fluid, but this will result in a floor that is already clean. Still, the implementation time is long enough to interfere with the time of mothers who are office workers or manufacturers to help their husband's income. . In the process of cleaning the floor, cleaning the floor can be done until the floor is clean so that the children are comfortable playing on the floor. The process of cleaning floors can be done in various ways, either manually or automatically. To clean the floor with a large floor size more quickly, the floor is cleaned with machine power. But the range and limitations of floor cleaning machines exist. So it is necessary to make a robot that works automatically without human assistance to do the cleaning so that the job is done quickly and the area limit of the cleaning results is greater. The system will work using penggerak technology remotely using Bluetooth. This system aims to connect communication between wheeled robots and smartphones via Bluetooth communication media. From the test results, the author has successfully applied Bluetooth technology to a wheeled robot by providing instructions such as forward, backward, turn right, turn left, and stop. This robot is used to clean floors quickly and practically so that it can be done by itself.

Abstract

Various techniques are used to protect digital information, especially information that is kept secret from people who are not entitled to the right of access to information, one of which is the technique of steganography. Steganography technique is a technique used to secure data by inserting or hiding data into an object without changing the shape of the object; one of the objects is a digital image. The steganography technique also has several methods, namely the Spread Spectrum method. Spread Spectrum is a method of communication where information signals are spread across all available frequencies by selecting where to insert data at low frequencies and adding pseudo-noise (PN). This study secures text data with the Spread Spectrum steganography technique on digital image objects by the steps of changing the value of the RGB pixel image and text data into binary, spreading the text data, followed by key generation and the modulation process of spreading text data with the generated key results. To produce a stegano image with an RGB pixel value that changes the value of 0 to 1 value that does not affect the color reproduction of the RGB pixel image.

Abstract

Honey guava is guava that has an extraordinarily sweet taste. The level of sweetness of honey guava can beat the sweetness of apples and other fruits. Quality seeds are the main thing to get planting that can provide optimal results. Quality seeds come from pure varieties, free from pests, diseases, and treatments suitable for this type of honey guava. This application can help farmers to obtain information on determining the best quality of honey guava seeds by applying the TOPSIS method and can be better selected based on the specified criteria. The application of the TOPSIS method uses the PHP programming language and MySQL database, which states that the best alternative is the alternative that has the shortest distance from the positive ideal solution and the farthest distance from the negative ideal solution, so the best alternative is the alternative that has the largest percentage, namely Green Deli guava. With a value of 77.97%.

Abstract

Small Medium Enterprises (SME) play an important role in the economic growth of Indonesia, and it was no exception in Sleman Regency, D.I. Yogyakarta province. This study aims to investigate and to recommend factors driving SME success by using formal concept analysis (FCA). Eleven factors and 36 subfactors were found based on the literature study to be further tested against a dataset based on interviews of 14 SMEs from seven different business sectors. With 95 attribute values from the attribute scaling process, the FCA results showed 641 concepts and concept lattice visualizations. Using a support threshold of 64%, seven intents were found to be more important, while other intents not included in the iceberg concept lattices were considered to be less important. The findings show that five factors (i.e., customers, products, human resources, networks, and external influences) play more important roles in driving SME success in Sleman Regency than the other six factors (i.e., characteristics, finance, competitors, market, technology, and government policy).

Abstract

The Indonesia government has started to prepare the strategies by setting the new policies regarding the spread of the coronavirus (Covid-19) since the first case was found on March, 2nd 2020. One of those policies is appealing to all government staffs/State C3il Apparatus and pr3ate employees to apply the system of remote working (Work from Home). To support the act3ity of remote working, the employees have been using some applications for online meetings to communicate with colleagues, superiors, and business partners in resolving the workloads without direct physical contacts. These applications needed are Zoom, Google Meet, Skype, and Webex. The writer conducted a study using the Analytical Hierarchy Process (AHP) method to determine the selection of the appropriate application for online meetings according to the priority criteria required by the employees who work at home. AHP method can provide the best order that will produce criteria and alternat3es with the highest values. The research was conducted based on the criteria for application features, ease of use, number of participants, duration of time, bandwidth requirements, and application security. The result for alternat3es with priority results was the Zoom application with the highest value of 0.341 (34.1%), followed by Google Meet with a value of 0.319 (31.9%), Skype with a value of 0.187 (18.7%), and Webex. With a value of 0.153 (15.3%) as the lowest order.

Abstract

Identification process type of bird lovebird, usually determined by parameters characteristic feather color of birds lovebird. Parameters to define the type of bird lovebird usually done manually by using the sense of sight. This way has a weakness that is, it takes a long time and results in an invalid identification. Based on that weakness, the researcher designed an identification system type of lovebird birds by using the Matlab programming language. Identify the type of lovebird bird conducted by researchers, namely color analysis of lovebird bird feathers. Image data were taken in the form of bird samples, lovebird josan, albino, and lutino by using a DSLR camera and identification algorithm K-means Clustering. The system is divided into two stages, namely the training stage and the testing phase. The training stage uses 30 bird images recognized according to type resulting in an accuracy level of 100%. While The testing phase uses 24 bird images, 22 images of lovebird birds identified according to their type, and two recognizable lovebirds images but not according to its kind resulting in an accuracy level of 91,67%.
