Logika Fuzzy adalah suatu cara yang tepat untuk memetakan suatu ruang input ke dalam ruang output. Untuk sistem yang sangat rumit, penggunaan logika fuzzy (fuzzy logic) adalah salah satu pemecahannya. Sistem tradisional dirancang untuk mengontrol keluaran tunggal yang berasal dari beberapa masukan yang tidak saling berhubungan. Karena ketidaktergantungan ini, penambahan masukan yang baru akan memperumit proses kontrol dan membutuhkan proses perhitungan kembali dari semua fungsi . Kebalikannya, penambahan masukan baru pada sistem fuzzy, yaitu sistem yang bekerja berdasarkan prinsip-prinsip logika fuzzy, hanya membutuhkan penambahan fungsi keanggotaan yang baru dan aturan-aturan yang berhubungan dengannya.Secara umum, sistem fuzzy sangat cocok untuk penalaran pendekatan terutama untuk sistem yang menangani masalah-masalah yang sulit didefinisikan dengan menggunakan model matematis Misalkan, nilai masukan dan parameter sebuah sistem bersifat kurang akurat atau kurang jelas, sehingga sulit mendefinisikan model matematikanya.Sistem fuzzy mempunyai beberapa keuntungan bila dibandingkan dengan sistem tradisional, misalkan pada jumlah aturan yang dipergunakan. Pemrosesan awal sejumlah besar nilai menjadi sebuah nilai derajat keanggotaan pada sistem fuzzy mengurangi jumlah nilai menjadi sebuah nilai derajat keanggotaan pada sistem fuzzy mengurangi jumlah nilai yang harus dipergunakan pengontrol untuk membuat suatu keputusan. Keuntungan lainnya adalah sistem fuzzy mempunyai kemampuan penalaran yang mirip dengan kemampuan penalaran manusia. Hal ini disebabkan karena sistem fuzzy mempunyai kemampuan untuk memberikan respon berdasarkan informasi yang bersifat kualitatif, tidak akurat, dan ambigu. Fuzzy logic is an appropriate way to map an input space into an output space. For very complex systems, the use of fuzzy logic is one solution. Traditional systems are designed to control a single output that comes from multiple unrelated inputs. Because of this independence, adding new inputs will complicate the control process and require recalculation of all functions. On the other hand, adding a new input to a fuzzy system, namely a system that works based on the principles of fuzzy logic, only requires the addition of new membership functions and the rules associated with it. In general, fuzzy systems are very suitable for reasoning approaches, especially for systems that handle Problems that are difficult to define using a mathematical model For example, the input values and parameters of a system are less accurate or unclear, making it difficult to define the mathematical model. Fuzzy systems have several advantages when compared to traditional systems, for example in the number of rules used. Initial processing of a large number of values into a membership degree value in the fuzzy system reduces the number of values to a membership degree value in the fuzzy system reducing the number of values the controller must use to make a decision. Another advantage is that fuzzy systems have reasoning abilities similar to human reasoning abilities. This is because the fuzzy system has the ability to respond based on information that is qualitative, inaccurate, and ambiguous.

Fuzzy logic is considered capable of mapping input into output without ignoring existing factors. Fuzzy logic is very flexible and tolerant of existing data. By using fuzzy logic, a model will be produced from a system that is able to estimate the perceptions of immigrants to local wisdom. The factors that influence the determination of immigrants' perceptions of local wisdom with fuzzy logic are the attitude of immigrant communities. Society's socio-cultural life is shown by the many links to other social life, such as ideology, lifestyle, and economy. This means that changes in one socio-cultural life will affect other social and cultural lives. Therefore this system is made so that the public can know, study and examine the variety of local wisdom, examine the role of indigenous and immigrant people in preserving local wisdom and study the strategies of indigenous and immigrant populations in limiting conflict and so on by applying fuzzy mamdani methods that are expected to provide decisions good in responding to the perceptions of immigrants towards local wisdom in West Kinali Pasaman.

An information system is already a necessity by a school in running a better administrative system. The administrative information system using information technology with the help of computers is very helpful in the smooth operation of the school. One of the school's operations that is the principal for supporting operations is the payment of Educational Development Contributions (SPP). A more effective and efficient tuition payment procedure can streamline all school operational activities. This study aims to improve the administration of tuition payments with a whatsapp gateway-based system. This system can perform all SPP payment procedures on a mobile or mobile basis. The data processed in this study were sourced from the administration system for paying tuition fees at Mukomuko High School (SMA). The system uses PHP programming language tools and MySQL database. The result of this research is a computerized SPP payment administration system. So that the school administration can control tuition payments more effectively and efficiently. So that this system is very precise and fast in the administration of tuition payments and becomes a reference for other administrations in order to assist the administrative process and improve time efficiency and provide the right information.

Many various types of industrial companies use aluminum to support their industrial productivity. One of the reasons companies use this aluminum material is because aluminum is a good electrical conductor, light and strong. In determining which aluminum metal is suitable to be used to make ordering equipment, of course the metal with the best quality must be chosen so that the production of aluminum equipment is in demand by many consumers. Multi Factor Evaluation Process (MFEP) method, all criteria which are important factors in making considerations are given weighting. (weighting) is appropriate. Decision making using the Multi Factor Evaluation Process method is carried out subjectively by considering several factors that influence alternatives. While selecting metal, SMEs still record manually, so it takes quite a long time to make decisions. Not only that, determining the quality of aluminum metal also involves visual observations just by looking at the durability and assessing the physical metal. To overcome the problems faced by the old system. then a new system was formed, where the selection process could be carried out by Toko Berkah Qory Siregar Aluminum without waiting a long time . The results obtained based on calculations are Aluminum A, namely Blue Sky Aluminum with a preference value of 100.

completed quickly and performed effectively and efficiently, especially in the agricultural sector. Pesticides are chemical or organic substances that farmers use to protect rice plants from pests , so farmers often have difficulty choosing pesticides that will be used to prevent rice pests. In fact, the large number of pesticide products on the market and their very different advantages make farmers confused in determining pesticide choices. The Harapan Jaya farmer group always provides counseling and training regarding the management of agricultural products, therefore the farmer group continues to maintain rice production to avoid pests and there is no shortage of rice plants at this time by using pesticide products on the market. Decision Support Systems (DSS) are systems that are able to provide problem solving abilities and communication abilities for problems with structured and unstructured conditions. The method in the decision support system is Multi Objective Optimization on the basis of Ratio Analysis (MOORA). The results obtained from this calculation method are Rodenticide with a value of 0.288 which is ranked first and the fifth rank is Insecticide with a value of 0.047. By implementing a decision support system using the MOORA method, it is hoped that it will help select interconnected outputs, because the decision results are based on criteria data in determining the best pesticide for rice plants
