Abstract

The problem of hot air temperature can disrupt indoor comfort and energy efficiency. The use of AC as a solution to cool the room is often not optimal, with problems such as AC remaining on when the room is empty and arbitrary temperature settings, which can accelerate device damage. To overcome this problem, this study proposes the development of an AC control and monitoring system that utilizes the Fuzzy Mamdani method based on the Internet of Things (IoT). The Fuzzy Mamdani method was chosen because of its ability to handle uncertainty and variability in temperature settings, while IoT allows the system to monitor and control the AC in real-time via the internet. The proposed system is designed to monitor the condition of the AC, automatically adjust the temperature based on actual needs, and provide information for corrective action if necessary. With this system, it is expected that the use of AC can be optimized, energy efficiency increased, and the service life of the AC can be extended. This study shows the importance of implementing a Fuzzy Mamdani and IoT-based control system to overcome the suboptimal use of AC, improve comfort, and reduce energy consumption. The results of this study are expected to make a significant contribution to more efficient AC management in educational environments and can be a model for similar applications in other fields. From the results, the room temperature tested was 25°C with humidity reaching 80%. Based on data processing using the Fuzzy Mamdani method, the results of the decision for the recommended AC temperature were 23.3°C. These results are in accordance with the results of manual testing.

Abstract

Non-Cash Food Assistance (BPNT) is a type of assistance managed by the Ministry of Social Affairs. The problem that often occurs when selecting recipients of non-cash food assistance previously was choosing families receiving non-cash food assistance without complying with the specified requirements or criteria. In the selection of families receiving non-cash food assistance, there is still a family attitude such as the village head and his staff who choose families receiving non-cash food assistance. This is certainly very bad, resulting in poor people not getting assistance and will also cause social jealousy among residents and not produce community welfare. A decision support system (DSS) is a system that is able to provide problem-solving capabilities and communication capabilities for problems with semi-structured and unstructured conditions. In the decision support system, the MABAC method can be applied which is able to produce the best decisions and several inputted alternatives. The results obtained from the process carried out were that A4 was the selected alternative with the highest value, namely 0.602

Abstract

Rubber plant is one of plants that produces latex which can be used as materials production of vehicle tools, health equipment, mat and other kinds of equipment. In PT Gergas Utama, Wampu Sub-district, District of Langkat, a good and proper quality of ruber plants are still determined by applying conventional method of Meter Lock usage. The criteria to produce International standard Latex are the age of rubber plants, winding width, and climate or weather. In the research, the Mamdani Fuzzy method was applied as the Decision Support System in order to determine the best quality of latex which can optimize the time and can overcome failures in determining latex quality. Fuzzy variables used in the research are the age of rubber plants, winding width, and climate or weather. The Fuzzy set used in each variable are is young (0-6), medium (3-12), old (9-15), small ( 0-0.8 ), medium (0.4-1.6 ), big (1.2 -2 ), rain ( 0-20 ), transition ( 15-30 ), dry (25-35). Fuzzy Mamdani method consists of Fuzzification, Rule Formation, Inference Engine, Defuzzification and Matlab Programming

Abstract

The Indonesian Institute of Technology and Business is an institution engaged in the field of Education. Scholarship is a gift in the form of an award or in the form of financial assistance given to people who have achievements that aim to be used as a continuation of education that will be taken during education. In addition, scholarships are also given to students as an appreciation or support for outstanding students. This research was made with the aim that the Right Target, Right Amount and Timely scholarship program can be implemented in determining scholarships to improve academic achievement at the Indonesian Institute of Technology and Business. Based on the existing problems, the authors analyze and design an application system built using Matlab software by combining fuzzy logic and Matlab GUI.

Abstract

Kegiatan pengabdian kepada masyarakat ini berupa sosialisasi tentang pentingnya menjaga keamanan data menggunakan Teknologi Informasi. Pengabdian ini bertujuan untuk membantu para masyarakat di Kantor Camat Batang Serangan agar memproleh informasi tentang kemajuan Teknologi Informasi dan bagaimana cara menjaga keamanan data agar tidak mudah dicuri dan dimanfaatkan oleh oknum-oknum yang tidak bertanggung jawab. Subjek pada kegiatan pengabdian ini adalah masyarakat beserta perangkat yang ada di Kantor Camat Batang Serangan. Metode dalam pengabdian masyarakat ini berupa sosialisasi yang dilakukan dengan pemberian informasi manfaat dan peran Teknologi Informasi dalam menjaga keamanan data dan cara pencegahan dalam menghadapi pencurian data seiring perkembangan Teknologi Informasi dimasa sekarang ini. Hasil dari kegiatan kepada masyarakat terlihat bahwa masih banyak masyarakat saat ini yang belum peka terhadap bahaya dari penyalahgunaan data dan infromasi, sehingga dengan adanya sosialisasi ini diharapkan dapat membantu masyarakat mendapatkan bekal pemanfaatan Teknologi Informasi yang dapat digunakan sebagai langkah preventif awal dalam mengamankan data dan informasi mereka tentunya dapat mengurangi kecemasan dalam melakukan akses internet khususnya dalam upaya mencari dan melakukan eksplor terhadap pengetahuan yang lebih luas. Berdasarkan dengan survey yang telah dilakukan sebelum dan sesudah proses pengadian didapatkan peningkatan pemahaman terhadap keamanan data tersebut dimana sebelum dilakukan pengabdian pemahaman masyarakat sebesar 75% dan setelah dilakukan sosialisasi pengetahuan meningkatn sebesar 83%. Terjadi peningkatan sebesar 8% yang menandakan bahwasannya sosialisasi berhasil dilakukan.
