<![CDATA[This research topic discusses the comparison of the K-Means and C4.5 algorithms in the application of data mining to predict aquarium sales in a company. K-Means is a clustering algorithm that functions to group data based on similarity, for example grouping customers based on frequency or type of purchase. This helps companies understand market segments and design marketing strategies accordingly. Meanwhile, C4.5 is a classification algorithm that builds decision trees based on important attributes that influence sales, such as price, season, or promotions. This algorithm is able to predict sales categories, such as increases or decreases, based on historical data. By comparing these two algorithms, the research sought to find out which algorithm is more effective in helping companies predict sales and make strategic decisions. A combination of the two can also be used, with K-Means grouping the data first, then C4.5 classifying each segment formed. These results can provide more accurate sales predictions and more effective marketing strategies. This research is important to understand the effectiveness of algorithms in data mining to improve business decision making.]]>

<![CDATA[Increasing productivity in the agricultural sector increasingly requires modernization of plant planting technology. This can be done by encouraging human resources such as helping farmers to be interested in knowledge about better and more appropriate agricultural techniques. Good agricultural technology must have a positive impact on the surrounding environment, not have a negative impact on human health and the surrounding environment, and be accessible and affordable to farmers. IoT tools are able to monitor soil through sensors that can measure soil conditions in real time. Sensors can observe various aspects of soil conditions, such as pH, humidity, temperature, and nutrients. IoT technology in the agricultural sector is utilized to achieve progress in melinjo plant production. Sensors as devices used can provide information on conditions such as soil humidity, air temperature, and humidity levels. Data obtained from sensors are sent via the internet to an intelligent system for analysis. The results of this analysis can provide information for farmers to make the right decisions to provide appropriate nutrition. Community service activities contribute to increasing melinjo plant agricultural yields in Dalu Sepuluh Village through the use of IoT technology for automatic plant watering.]]>

<![CDATA[Lack of knowledge about the problem of acne for the people who do not know how to prevent early steps to prevent acne more inflamed. This system can help doctors to facilitate patient diagnosis and can save the patient's medical records for consideration of the results of diagnoses of new problems that will come. Therefore, this study aims to produce an expert system for diagnosing acne problems on the face using the case base reasoning method. The algorithm used for the CBR method is the Nearest Neighbor Retrieval algorithm for determining the value of disease symptom weighting based on: if the symptoms of the selected disease will be the same value of 1 and if the symptoms chosen are not the same will be value of 0 to the symptoms of old disease cases. In this CBR method the system will determine the solution of the problem with the highest level of similarity value which will be chosen as the solution of the new problem.]]>

<![CDATA[Rapid development of digital image technology secret causes images require security aspect. Reviews These digital secret image can be encrypted using cryptographic methods. After being encrypted, the image is randomized, so that if it is Obtained by an unauthorized party, the image has no meaning. The cryptographic algorithm used in this study is Gifford method. The Gifford method is a stream cipher, a symmetry encryption algorithm that transforms the data character by character. Gifford has 8 registers filled with key bits. The processes performed by the Gifford method are the Output Function process, the 1-bit Sticky Shift Right process, the 1-bit Left Shift process, the XOR operation and the shift register operation to the right. The decryption process must use the same key as the encryption process in order to Obtain the original image.]]>

<![CDATA[Respiratory tract infections are infectious diseases that interfere with the process of human breathing. When the breathing process takes place, there are often various kinds of diseases, most of which can only be treated by a lung specialist. The arrival of a pulmonary specialist for consultation can take hours and is expensive. Then we need an expert system that can quickly find out the type of disease in human breathing and how to handle it and the solutions that will be provided. Expert system is a system that uses human knowledge to find out the system that is entered into a computer and then is used to solve problems that usually require expertise or human expertise. One application of an expert system to diagnose respiratory tract infections is to use the certainty factor method. The certainty factor method is a method used to solve problems from uncertain answers, and also produce uncertain answers. This uncertainty is influenced by two factors, namely uncertain rules and uncertain user answers. The research aims to build an expert system application for handling respiratory tract infection problems with Visual Studio 2010 as a tool for designing applications and using Microsoft Access 2007 Database as a database. This expert system is able to calculate similarity in weight calculation based on symptoms of respiratory tract infection using certainty factor methods and provide reports using crystal reports]]>

<![CDATA[The research conducted through community service aims to develop artificial intelligence (AI)-based software capable of detecting students' emotions at SMKS Methodist 8 in real time, as an effort to support teachers in implementing a more adaptive and responsive learning approach. This system is designed by integrating facial recognition and emotional expression analysis through a camera, which is then processed using the Certainty Factor method to determine the confidence level of the detected emotional classification. This approach allows the system to generate emotional diagnoses with a reliable degree of confidence, based on predefined parameters. Test results have shown that the software is capable of detecting several basic emotions such as happiness, sadness, anger, and neutrality with an adequate level of accuracy. The implementation of this system in classrooms is expected to assist teachers in quickly identifying students’ emotional states, allowing learning strategies to be adjusted accordingly to improve the effectiveness of the learning process. Therefore, this technology offers an innovative solution in supporting the improvement of education quality through an approach that focuses on individual students.]]>
