Penelitian ini membahas simulasi antrian di bank dengan menggunakan metode gamma. Tujuan penelitian ini adalah untuk merancang dan menerapkan metode gamma untuk mensimulasikan antrian layanan pelanggan bank. Dalam sistem antrian biasanya ada tiga komponen yang saling berhubungan satu sama lain kedatangan, antrian atau antrean. Melalui simulasi yang akan dilakukan dapat dilihat bahwa kinerja sistem yang diamati akan dikoreksi sehingga mendapatkan perbaikan agar benchmark untuk layanan dapat berjalan lebih baik lagi. Dalam penelitian ini peneliti menggunakan distribusi Poisson untuk kedatangan pelanggan tunggal dengan teller tunggal dan antrian tunggal mengikuti aturan FIFO. Berdasarkan hasil penelitian, ada empat server yang memadai untuk melayani, jika hanya satu server akan menghasilkan waktu tunggu rata-rata yang sangat panjang yang menyebabkan pelanggan bosan, sementara dengan dua server masih menghasilkan rata-rata lama menunggu waktu dan menyebabkan antrian, jika menggunakan tiga server jumlah waktu tunggu tidak terlalu lama dan tidak membuat antrean panjang. Untuk penelitian selanjutnya diharapkan akan dikembangkan simulasi antrian yang memiliki kedatangan atau layanan dengan distro lain dan dapat digunakan sebagai acuan dalam pengambilan keputusan guna memaksimalkan waktu layanan pelanggan atau menambah jumlah server sebagai pelayan, dan meminimalkan server jika dianggap berlebihan dalam layanan untuk meminimalkan biaya operasional

Perkembangan kriptografi terus berlanjut walaupun algoritma yang terkemuka dan dinilai kompleks sudah mulai bisa dipecahkan. Algoritma- algoritma kriptografi klasik seperti Hill Cipher dan Vigenere Cipher pin memiliki kelemahan akan kriptanalisis. Algoritma hill cipher dan vigenere cipher merupakan salah satu metode dari beberapa metode yang digunakan untuk melakukan kerahasian data, hill cipher adalah algoritma keamanan data menggunakan perhitungan perkalian matriks, sedangkan vigenere cipher adalah algoritma yang melakukan enkripsi sekaligus sebuah teks yang terdiri dari beberapa huruf. Jika kedua algoritma diatas dikombinasikan dalam sebuah aplikasi keamanan data, maka akan lebih sulit memecahkan sandinya bila dibandingkan dengan hanya menggunakan satu algoritma saja. Penggabungan antara dua algoritma tersebut menjadi sebuah solusi untuk memperkuat algoritma menjadi lebih sulit untuk dapat dipecahkan dan untuk mengecoh kriptanalisis. Filet eks yang telah diamankan menggunakan Algoritma Vigenere Cipher akan diamankan lagi menggunakan Algoritma Hill Cipher. Implementasi sistem menggunakan perangkat lunak Visual Basic.Net 2010. Hasil dari sistem ini berupa file yang ter-enkripsi (cipherfile) yang tidak bisa dimengerti. Kemudian fileteks kembali normal setelah di-dekripsi.

Communication is a very important activity. Communication is carried out with the aim of exchanging information between several individuals. Communication can be done in various ways. Those who wish to communicate with each other can meet in person or through intermediaries. There are several types of media that function as intermediaries of information. You can use several media such as print media, electronic media, and online media to get various information. Digital communication in the modern era is not far from the Internet because almost all digital communication tools use the Internet. Internet needs vary greatly from old to young, because Internet needs are different, connection management is needed (Management Bandwidth) so that client requests with high connections do not interfere with clients with relatively low connection requests. One of the tools commonly used for connection management is MikroTik with the Peer Connection Queue (PCQ) feature. The reason for choosing Mikrotik is because Mikrotik has complete features at an affordable price. The importance of connection management is to maximize the connection provided by the ISP so that clients can use the Internet without buffering.

The Trans Binjai Bus or Bus Rapid Transit (BRT) which is managed by the Binjai City Transportation Service is a bus system that is fast, comfortable, safe and on time. Each BRT system must use a different improvised system, although the improvements are shared with other BRT systems. The queue system in operations carried out by the Trans Binjai Bus often occurs overcrowding and even builds up at one point which results in Trans Binjai Bus users having to wait and not know the departure schedule. Therefore, the queuing system in the operation of the Trans Binjai bus must be carried out in a systematic and scheduled manner so that accumulation at one point and delays can be avoided. Queue is a waiting line situation where a number of physical units (entrants) are trying to receive service.

Formalin is very dangerous for human health and for that we need to detect the content of formaldehyde in these foods so that this abuse should be known easily. For that we need a tool that can detect the content of formalin in food. The use of a gas sensor is the fastest way to detect formalin used in food because it does not require a chemical process that is not instant. The MQ-138 sensor is used as a formalin detection sensor in food where this tool uses an Arduino microcontroller as a processor and data processor for the MQ-138 sensor readings which then the sensor readings will be displayed on a 16x2 LCD display, and then the tool system is inputted with a fuzzy method. logic, with fuzzy logic that is safe, a little formalin, and a lot of formalin.

Land and Building Tax or abbreviated as PBB is a fee that must be paid for the existence of land and buildings owned by the community or residents. The determination of PBB in Binjai City is based on the application of the Land Value Zone (ZNT) which is close to the market price, which will be able to create equitable development throughout Binjai City. BPKPAD (Regional Revenue and Assets Financial Management Agency) Binjai City is a government agency that receives PBB payments from the community. Data - data on PBB payments for the people of Binjai City have been stored in an existing system and every year it will continue to increase so that it will cause data accumulation in the land and building tax archives. A data processing system is needed to manage these data, one of which can be done with data mining which can process piles of data into useful information and can be utilized by grouping PBB data based on criteria. Clustering is a method in data mining that can be used to automatically detect clusters of adjacent records that have a certain definition in all variables. K-Means algorithm is a simple algorithm to classify or group a large number of objects with certain attributes into groups (clusters). So that this system can be used as input for the Binjai City BPKPAD in finding solutions to increase regional income from PBB payments.

Red chili is one type of vegetable that has a high economic value. Chili is usually used in the form of fresh or dried or cooked, for ingredients for kitchen spices, medicinal ingredients, the needs of the food industry, and home industries. . However, it is common for farmers to harvest red chilies that are not yet ripe or even ripe, such as reddish-brown, red-black (rotten). This can lead to a lack of maturity level of red chili and the quality of the red chili. From the input pattern/image of chili as training data and training targets, it is possible to identify the ripeness of chilies using the backpropagation method. Based on the image data of chilies, it can recognize the pattern of chilies that have a maturity level that is in accordance with the digital image by using the backpropagation method and using the MATLAB application, with an accuracy level of training and testing data that is 97,78%.

Scheduling is a process, method, manufacture, or schedule to be included in the schedule (KBBI). Scheduling that is needed in general and that occurs at one point of education in making study schedules requires various supporting factors from the division of teacher tasks. Based on this, efforts to facilitate learning schedules are made to optimize an activity so as to increase productivity and effectiveness.To carry out learning activities that are carried out conventionally and for a long time, teachers who have teaching schedules in two or more different classrooms at the same time must be revised by changing their respective schedules or reducing the hours that occur as guided by the teacher. At SD S Muhammadiyah Sambirejo, which is a school located in Sambirejo Village, Binjai District, Langkat Regency, and has several educators and educational staff at this school, I focus on the case study of learning scheduling, so that teaching and learning activities in a school must pay attention to the learning schedule and avoid clashes. This makes it easier to prepare a study schedule. The method used is linear regression as an optimization of learning scheduling. The results of testing the linear regression method in optimizing learning scheduling using linear regression with a total of 10 forecasting data as analysis and determining the forecasting result value of 2.0063334474495 obtained data results with the number of conflicting hours.
