Abstract

The selection of candidates to become Service Ambassadors is an important and complex process. Assessors need to consider many factors and the relative weight of each factor to ensure the best candidate is selected for the position. One method that can be used in candidate selection is the ORESTE method. The ORESTE method is a multi-criteria decision-making method developed by J.P. Brans and B. Mareschal in 1994. This method allows assessors to aggregate multiple criteria and consider the relative weight of each criterion to compare alternatives and produce a ranking of candidates based on the highest relative value. In the context of Service Ambassador selection, the ORESTE method can assist assessors in solving complex decision-making problems and ensuring the best candidate is selected for the position. The method allows raters to consider multiple criteria and consider the relative weight of each criterion, resulting in a ranking of candidates based on the highest relative value. Thus, the use of the ORESTE method in determining the selection of Tourism Ambassadors can simplify and speed up the candidate selection process, as well as increase accuracy and satisfaction in decision making. By using the ORESTE method, the results of the decision to select the winner of the Service Ambassador event are obtained with a preference value of 4.42

Abstract

Among teenagers or adults, body shape greatly affects a person's confidence. Most people will be very confident if their body shape is ideal, where the person will be very confident speaking in public. Different things with people who have a body shape that is too thin/fat, so their confidence is less to appear in public. To get the ideal body shape they will do everything possible, one of which is dieting, taking weight loss capsules, and so on. They do not know the dangers of dieting too strictly and taking weight loss capsules carelessly which can make them contract Nervosa disease. To get the results of the expert system, the case-based reasoning method will be used. After this application is built, the result obtained is the type of nervosa disease based on the symptoms felt by the user.

Abstract

The leaf staining disease caused by the fungus Curvularia sp. is a serious threat to palm coconut cultivation in Binanga Village. Surveys showed that the intensity of the attack reached 25-75% of the infected leaves, especially in seedlings aged <4 months. Humid environmental conditions, poor sanitation, and the use of infected seeds/seeds play a role in the spread of disease. Integrated control strategies combining healthy seeds/seedlings, environmental sanitation, alternate application of fungicides (azoxystrobin, mankozeb, chlorotalonil), insecticides (deltametrin, imidakloprid), and Gandasil D have proven effective. Implementing this strategy reduces the intensity of attacks by 80% and increases the percentage of healthy seedlings by 85%. Despite resource constraints, optimization of control strategies is carried out to the maximum extent possible. Strict monitoring, preventive measures, and planting of resistant varieties also play an important role. This research provides practical recommendations for increasing the production of high-quality palm coconut seedling sustainably in Binanga Village by implementing integrated control strategies against leaf spotted disease Curvularia sp.

Abstract

Increased global warming and awareness of the need to reduce greenhouse gas emissions have strengthened the focus on energy efficiency in various sectors, including the HVAC (Heating, Ventilation, and Air Conditioning) industry. In this context, the selection of air conditioning (AC) systems becomes crucial in providing thermal comfort. However, decisions regarding air conditioning systems are often complex as they involve considerations of energy efficiency, operational costs, system reliability, and environmental impact. To address this complexity, Complex Proportional Assessment (COPRAS) emerged as an effective multi-criteria analysis method. However, the application of COPRAS in determining AC system traffickers is still limited. This research explores the possible application of COPRAS in this context and identifies key factors to consider. The evaluation results show that Medan Elektronik and Citra Inovasi Prima are the top choices in the selection of AC system traffickers. This research is expected to contribute to the development of more sophisticated analysis methods in the HVAC industry as well as assist decision makers in selecting more appropriate and sustainable air conditioning systems.

Abstract

This research aims to evaluate the quality of university web pages in Medan City using two decision-making methods, namely Complex Proportional Assessment (COPRAS) and Organization Rangement Et Syntest De Relatonnelles (ORESTE). University websites play a very important role in reflecting the identity, vision, and mission of the institution, as well as improving its reputation in today's digital era. However, not all universities in Medan have implemented optimal standards in managing their web pages. Therefore, the results of this study show that based on the COPRAS method, there are 3 top universities, namely Muhammadiyah University of North Sumatra (UMSU) ranked first with the highest score of 100.0000, followed by Quality University with a score of 93.7500 ranked second, and Harapan University Medan with a score of 91.4063 ranked third. Meanwhile, using the ORESTE method also ranked UMSU first with a score of 5.00, followed by Universitas Pembangunan Panca Budi in second place, and Santo Thomas Catholic University in third place with a score of 7.17. The similarity of the first rank between the two methods shows consistency in the recognition of the quality of the UMSU web page. However, differences were seen in the second and third rankings, where COPRAS ranked Universitas Quality and Universitas Harapan Medan, while ORESTE ranked Universitas Pembangunan Panca Budi and Universitas Katolik Santo Thomas. This difference reflects the different evaluation approaches of the two methods. The findings are expected to assist universities in Medan in developing more effective strategies for improving user experience and strengthening institutional reputation.

Abstract

In communication, there is a process of transferring information from the sender to the recipient. The information sent must be the same as the information received. If there are differences, it means that there has been a data change process carried out by irresponsible parties. One technique for changing the content of information is man in the middle. The data changer will receive information from the sender, then change it and forward it to the recipient, so that the changed information appears to have come from the sender.To protect information, this can be done by utilizing the science of cryptography and steganography which aims to protect information by changing it to another form or by inserting the information into other media. In this research, to protect information the Caesar Cipher Algorithm is used, this algorithm will change the letters in plaintext to another letter (ciphertext) by using an alphabetical shift according to the number in the form of the key used, namely > 1 and < 26, then the Reverse Cipher algorithm is carried out, namely changing the position of the letters of the plaintext from the first order to the last order and so on. The encrypted information will then be inserted into a video using the Steganography Algorithm, namely Least Significant Bit (LSB). Before being inserted, the video will first be converted into several image frames, then in one frame the information will be inserted. This can be done because the frame is a collection of RGB arrays which have values 0-255 or 0 and 1. So the insertion is done in bit form. Frames containing information will then be converted back into a video.On the receiving side, the video will be converted into a frame, next is the process of retrieving the information that was previously inserted. The information that has been taken is then reversed in order and then shifted using the Caesar chipper algorithm according to the key used by the sender, then the first letter of each word is changed to capital, so that the information sent is the same as that received. The implication of this research is that it is a way to combine cryptography with steganography as an information security technique.

Abstract

Kampung Sejahtera is a densely populated area in the river basin of Medan City which often faces challenges in overcoming the spread of false information or hoaxes which can cause confusion and social loss. The lack of digital literacy among their members exacerbates this situation, so efforts are needed to improve their ability to manage digital information effectively. This service aims to optimize digital literacy among Kampung Sejahtera members in order to tackle the spread of hoaxes. Specifically, this service evaluates the current level of digital literacy, identifies types of hoaxes that often circulate, and develops and implements effective digital literacy programs. The effectiveness of the program is evaluated through post-training surveys and observation of member behavior after training. The service shows that members' initial digital literacy level is relatively low, especially in the ability to identify and counter hoaxes. The most frequently spread hoaxes include false information about health, politics and sensational news. After participating in the digital literacy training program, it is hoped that there will be a significant increase in members' ability to recognize and reduce the spread of hoaxes. They become more critical and careful in verifying information before sharing it. Optimizing digital literacy through appropriate training programs has proven effective in tackling hoaxes in Kampung Sejahtera.

Abstract

This research aims to develop an expert system based on the case-based reasoning method for diagnosing anxiety disorders. Anxiety Disorder is a mental health disorder that is often experienced by the public but is often not detected correctly. The case-based reasoning method was chosen because of its ability to utilise previous cases to solve new problems that have similarities. Case-based reasoning uses four main stages: retrieval, reuse, revise, and retain. The case-based reasoning method is implemented using case data obtained from psychology clinics and interviews with mental health experts. Testing the case-based reasoning method shows a high level of accuracy in diagnosing various types of Anxiety Disorders, such as Generalised Anxiety Disorder, Panic Disorder, and Specific Phobias. The results of this study show that the case-based reasoning method can be an effective tool in helping mental health professionals diagnose Anxiety Disorders more quickly and accurately. After searching using the symptoms obtained, the percentage of each type of disease is the percentage of Generalised Anxiety Disorder 35.7%, the percentage of Panic Disorder 30.7%, and the percentage of Specific Phobias 65%.
