Among them is the difficulty of SMEs in developing their marketing strategy. Furthermore, the KOL Marketing strategy is one of the marketing strategies that have recently become a trend to be implemented in many business sectors. KOL marketing is considered more effective in influencing audiences to make purchasing decisions so that it has an impact on rapid sales. Unfortunately, KOL marketing is identically implemented by big brands because it is assumed that KOL marketing costs are relatively expensive, while SMEs themselves are very limited in terms of financing. In the midst of limited funding and poor marketing implementation, Nana Baby Carrier as one of the RKS Sleman SMEs was able to adapt KOL marketing strategies and implement them according to the SMEs conditions. KOL Marketing concepts and strategies are imitated and modified to remain relevant to SME business conditions. So it actually gives birth to a KOL marketing concept that is right on target and more efficient. This research aims to determine the KOL Marketing Strategy in Improving the Product Branding of the SMEs of RKS study on the SMEs Nana baby carrier. KOL marketing itself is a development of digital marketing. This research uses qualitative descriptive research methods and characteristics assisted by interview data collection techniques with two informants (Founder and Cofounder Nana Baby Carrier) and document analysis. The research results show that there are six ways to create a strategy for using KOL to increase brand awareness.</p> 2024-02-17T00:00:00+00:00 Copyright (c) 2024 Proceeding of International Conference on Information Science and Technology Innovation (ICoSTEC) https://prosiding-icostec.respati.ac.id/index.php/icostec/article/view/97 Detection Of Worker Presence Using The Yolo Model Based On Digital Image 2024-03-20T17:05:53+00:00 Jazmi Matondang jazmimatondang@gmail.com Rika Rosnelly rikarosnelly@gmail.com Roslina Roslina roslinanich@gmail.com <p>The large number of workers requires a long time for administrative officers to check worker attendance manually so that work efficiency cannot be achieved. It takes quite a long time to check worker attendance manually. Attendance reports are sent to office social media, including the names of each worker and so on. This is considered less efficient and sufficient as a basis for providing a solution by detecting worker presence using the YOLO (You Only Look Once) method, so that the process of checking worker attendance can be more efficient. The test results with low pixels and training of 100 epochs, namely 224x192 pixels, obtained an accuracy of 86%, while the best test results were using dimensions of 1088x640 pixels in the worker's photo as test data with original photo dimensions of 1080x1920 pixels in the YOLO model which succeeded in detecting faces with 100% accuracy. So, it can be concluded that the higher the pixel value, the better the accuracy tends to be. However, in this case it also has pixel limitations that are recognized by the model.</p> 2024-03-20T00:00:00+00:00 Copyright (c) 2024 Proceeding of International Conference on Information Science and Technology Innovation (ICoSTEC) https://prosiding-icostec.respati.ac.id/index.php/icostec/article/view/96 Securing Data Files Using RSA-ElGamal and Diffie-Hellman Algorithms 2024-03-20T16:57:55+00:00 Ameliana Sitohang amelianasihotang123@gmail.com Rika Rosnelly rikarosnelly@gmail.com Zakarias Situmorang zakarias65@yahoo.com <p>Data security involves efforts to protect and ensure three key aspects in the cyber realm: the confidentiality, integrity, and availability of data.

These values play a pivotal role in determining the graduation status of the santri (students) within the institution. This research investigates the application of feedforward neural networks (FFNN) architecture, focusing on the number of hidden layers and neurons per hidden layer, to develop a predictive model for the future graduation status of the santri. The study explores three different activation functions (Sigmoid, ReLU, and Tanh) and assesses their impact on model performance. Our findings reveal that the optimal model for predicting the santri's graduation status involves the use of the Tanh activation function in combination with four hidden layers and four neurons per hidden layer.

In terms of academic activities, UNRIYO has an Entrepreneurship course as a compulsory subject, and other entrepreneurship courses developed by the Faculty such as Technopreneur, Sociopreneurship and Health Technology and Innovation. Based on the results of the 2022 Tracer Study, UNRIYO graduates who have become entrepreneurs have not yet reached the desired number. This is of course UNRIYO's evaluation of the graduate profile which is expected to be in accordance with the entrepreneurial vision. One effort to overcome the problems described above is by increasing collaboration between UNRIYO, industry and the government. Collaboration is carried out through learning activities and activities carried out by UNRIYO through university business units. This collaboration is aimed at the UNRIYO academic community, especially students and academics who have an interest and desire to become entrepreneurs. The university incubation program is one of the efforts that UNRIYO can undertake to achieve its entrepreneurial vision and mission, as well as facilitating the development of startup businesses in Indonesia. This program provides benefits for universities, startup entrepreneurs, government and society. Even though there are still many obstacles faced, with good collaboration between universities, industry and the government, the university incubation program can be an effective solution in developing the creative economy in Indonesia. It is hoped that the UNRIYO higher education incubation program will provide opportunities for UNRIYO to participate in developing Indonesia's creative economy. Start-up businesses that are expected to pass incubation by the UNRIYO Center for Entrepreneurship Studies (ReCEnt) are businesses that apply advances in information technology and have innovation value in their products or methods.

Approaches to comparing object characteristics<br>in image processing can be divided into High Dimensional Feature<br>and Low Dimensional Feature approaches. Support Vector<br>Machine (SVM) is an accurate High Dimensional Feature method,<br>while Linear Discriminant Analysis (LDA) is a powerful Low<br>Dimensional Feature method. Some studies combine SVM with<br>LDA to reduce complexity and improve performance. In the<br>classification of palm fruit image diseases, the comparison<br>between SVM (High Dimensional Feature) and LDA (Low<br>Dimensional Feature) can be done with variations in dataset size<br>and the percentage of training and testing data in the research is<br>50:50, 60:40 and 70:30. Performance measurement is based on<br>accuracy, precision recall and f1-score values. The algorithm for<br>testing the validity of the accuracy results is k=5 Cross Validation.<br>The average test result on linear dicriminant analysis, the highest<br>prediction, namely 0.57, was obtained in the 1st iteration.<br>Meanwhile, the lowest average value was obtained in the 5th<br>iteration, namely 0.44. Then the predicted value for system testing<br>is 0.52. Meanwhile, the calculation of the support vector machine<br>testing results has the highest average prediction, namely 62.63%,<br>obtained in the 2nd iteration. The lowest average accuracy value<br>was obtained in the 4th iteration, namely 62.36%. Then the<br>prediction value for the testing data system was 62.57, obtained<br>from the average results of each iteration. This study aims to<br>compare the performance of the LDA and SVM algorithms in<br>classifying healthy and diseased oil palm fruit diseases with<br>variations in dataset size and percentage of training and testing<br>data. From the results of research conducted, SVM has an<br>accuracy of 72.02% at the 3rd percentage variation. Meanwhile,<br>LDA is 69.04% with the same percentage variation. SVM shows<br>that it is more effective in classifying images of sick palm fruit or<br>healthy fruit compared to LDA.</p> 2024-02-17T00:00:00+00:00 Copyright (c) 2024 Proceeding of International Conference on Information Science and Technology Innovation (ICoSTEC) https://prosiding-icostec.respati.ac.id/index.php/icostec/article/view/62 Questionnaire Based Hospital Patient Satisfaction Level Classification With Support Vector Machine 2024-02-15T07:47:30+00:00 Khoirunsyah Dalimunthe choyrun2@gmail.com Hartono hartonoibbi@gmail.com B.

Using nine questions as features and<br>measuring the patients' willingness to recommend RS Haji<br>Medan to others, we built three classification models with<br>Polynomial, RBF, and Sigmoid kernel functions. Out of the 86<br>responses we received, our t-test validation test revealed that all<br>the questions we asked are valid for use in the classification<br>process. The results show that the Polynomial model produced<br>the highest accuracy (90.5%), precision (91.8%), and recall<br>(90.5%) when compared to the RBF and Sigmoid models.<br>Furthermore, the generated model exhibits stable performance,<br>with an average difference of less than 7% between the training<br>and testing performance.

Focusing<br>on walking, riding, and swimming distances, our study employs<br>machine learning algorithms, including Random Forest (RF),<br>Support Vector Machine (SVM), and Multilayer Perceptron<br>(MLP), to predict PUBG player performance, with a primary<br>emphasis on solo matches. Our research encompasses data<br>collection, filtering, model configuration, data sampling, and<br>model evaluation stages to ensure data reliability and model<br>appropriateness. The results highlight the consistent superiority<br>of the Random Forest model, which demonstrates the lowest<br>Mean Squared Error (MSE), Root Mean Squared Error<br>(RMSE), Mean Absolute Error (MAE), and the highest Rsquared (R2) values in both training and testing phases. In<br>contrast, the SVM-Sigmoid model consistently delivers poor<br>predictive performance, emphasizing the significance of selecting<br>an appropriate model. In summary, this research unveils the<br>vital role of travel distance in PUBG player performance and<br>underscores the importance of data-driven decision-making and<br>model selection in achieving accurate and reliable predictions.<br>This contribution enhances our understanding of player<br>performance in the dynamic world of PUBG.</p> 2024-02-17T00:00:00+00:00 Copyright (c) 2024 Proceeding of International Conference on Information Science and Technology Innovation (ICoSTEC) https://prosiding-icostec.respati.ac.id/index.php/icostec/article/view/60 Exploring Student Learning Interests with Support Vector Machine in Pedagogical Strategies 2024-02-15T07:38:30+00:00 Tasya Fahriyani dipo.ar@gmail.com Hartono hartonoibbi@gmail.com B.
