Technology that is increasingly easy to use has been embedded in all aspects of life, appraisal system technology is one of many intelligent systems that facilitate human work in the level of accuracy of performance appraisal. The quality of the lecturer's performance is not good and quality, resulting in the reduced quality of lecturer dedication and the quality of students at STMIK Triguna Dharma Medan. Therefore, a method is needed to identify the causes of the optimal and effective assessment of lecturer performance to facilitate improving the quality of lecturers and students at STMIK Triguna Dharma Medan. Researchers use comparisons to find out which system is more effective and accurate in determining lecturer performance appraisal using DSS (Decision Support System). This decision support system is to determine the best criteria in determining the best value weights from a comparison of two methods, namely the ORESTE method with PSI (Preference selection index) in solving the material and determining the best level of accuracy of performance assessment in this case, where the ORESTE method uses the Besson process. rank which means this method uses ranking and ordinal data. The PSI (Preference Selection Index) method was chosen because it can determine the weight value for each attribute, in this case it can be continued with ranking which will be able to select each attribute from the best alternative from several existing alternatives, so that the results are obtained from the selection of the best weight. , namely the best lecturer performance

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

Air Conditioner or what is usually called AC is a room temperature cooling device which is usually placed in the upper corner of the room ceiling or in the corner of the room, which is sometimes not maintained and cannot be reached by the room owner. Almost all companies or large-scale businesses use Air Conditioning (AC) to create comfortable conditions so that all employees can work more optimally. However, this cannot be fully implemented because there are more units in a company than there are technicians employed by that company. Due to conditions like this, an idea was created that would make the work of technicians, especially AC technicians, in a company easier, a system that would be able to determine the condition. The latest Air Conditioner unit uses the Simplex technique and a medium distance signal, namely Microcontroller-based Bluetooth. Equipment that will be placed in every Air Conditioner (AC) unit in every air-conditioned room in a company

Kemampuan menghindar rintangan dapat diberikan kepada robot dengan berbagai cara, termasuk menggunakan sensor yang dapat mengukur jarak seperti sensor ultrasonik. Pemanfaatan sensor ultrasonik sebagai pendeteksi halangan dapat dilakukan dengan mendeteksi ada tidaknya pantulan gema ultrasonik akibat dari media pantul yang ada dihadapan sensor. Dalam melakukan geraknya, robot dirancang dapat menerima perintah dari pengontrol.[5] Sebagai medianya digunakan sebuah modul Bluetooth yang dapat berkomunikasi dengan smartphone sebagai pemberi perintah. Sebuah aplikasi yang dapat menerjemahkan perintah untuk berbelok, maju, dan mundur digunakan pada smartphone. Apabila sensor mendeteksi adanya penghalang dihadapannya, maka robot akan mencari solusi dengan cara membandingkan jarak di kiri dan di kanan robot. Jarak terjauh antara kiri dan kanan yang akan dipilih yang selanjutnya pengontrol akan diaktifkan kembali setelah robot memberi arah untuk melanjutkan aksi. Hasil percobaan menunjukkan bahwa robot dapat bekerja sesuai dengan apa yang diharapkan. Untuk hasil penelitian akan diteruskan sebagai media pembelajaran yang baik kepada mahasiswa yang ingin mendalami lebih jauh tentang robotika dan sistem kendali ataupun yang hanya ingin belajar robotika.

Bird pest attacks are one of the main causes of declining rice productivity in Deli Serdang Regency, especially during the grain ripening phase. This study develops the smartRicefield innovation, namely an automated bird pest repellent system based on the Internet of Things (IoT) and Artificial Intelligence (AI) using the YOLO11m image detection model. This study begins with collecting bird image datasets in rice fields collected from field image capture or dare sources, then labeled using the YOLO format, and wrapped with augmentation techniques to increase shape diversity. The YOLO11m model consisting of 125 image layers and 20,030,803 parameters with a complexity of 67.6 GFLOPs drilled for the next 100 epochs. The best model in the 86th epoch achieved 100% precision, 83.2% recall, mAP@0.5 of 86.3%, and mAP@0.5–0.95 of 69.3%. The Confusion Matrix Analysis showed good bird detection performance, but a high false positive rate in the background of the trigger image caused false triggers in the object testing. The system was tested in Deli Serdang rice fields with a detection latency of less than 1 second and an expulsion effectiveness of 90% at an effective distance of 10 meters. These results indicate that the integration of AI and IoT in Smart Ricefield is able to provide an effective real-time solution for bird pest mitigation, although improvements are still needed in dataset variations and expulsion mechanisms to increase the system's long-term resilience to all types of bird pests in the rice field environment.
