Abstract

As social beings, humans have a desire to socialize, to build deeper relationships with individuals they like, and also to get a spouse according to the criteria they like. However, there are often obstacles in finding a spouse, one of which is due to being too busy and an increasing workload. Luckily we live in an era of technology that makes it easier for us to interact with other people. The spouse selection application itself is quite common for several circles in Indonesia, but some of these applications are considered not fully providing services to recommend a spouse based on the criteria. Therefore, it is necessary to design an application that helps users find a spouse according to the criteria they like. In this application, the Simple Additive Weighting (SAW) method will be used to process data. The SAW method itself has the ability to find optimal alternatives from a number of alternatives with certain criteria.

Abstract

Pada saat ini industri perfilman di dunia sudah sangat hebat, dikarenakan perkembangan teknologi yang sangat pesat sehingga memberi pengaruh yang besar terhadap industri perfilman. Berkat perkembangan teknologi inilah yang membuat film-film yang dibuat menjadi semakin menarik, bahkan banyak munculnya kreator-kreator baru yang belajar membuat film dengan budget yang kecil mulai dari membuat film pendek maupun film cerita (feature film). Film yang berhasil cenderung memiliki rating film tinggi, sungguh menarik bukan jika dapat mengetahui keberhasilan suatu film yang telah dibuat atau belum dibuat dengan memprediksi seberapa tinggi rating film tersebut. Untuk memprediksi rating film digunakanlah metode data mining yaitu Naïve Bayes dan KNN, Naïve Bayes dan KNN adalah metode pengelompokkan statistik yang dipakai untuk memprediksi probabilitas anggota suatu class. Prediksi menggunakan faktor internal dan eksternal yang mempengaruhi keberhasilan film sebagai variabel independent dan rating film sebagai variabel dependent. Dari sistem yang dibuat dapat diketahui rating film sebuah film dan faktor-faktor yang mempengaruhi keberhasilan sebuah film. Dengan sistem ini diharapkan dapat mengefektifkan dan mengefisiensikan produksi sebuah film.

Abstract

TCP\IP protocol can be connected to various computer data networks in the world. This protocol increasingly exists and is needed so that many parties develop it to vote through this protocol. Voice Over Internet Protocol technology is the answer to that desire. This technology is able to convert analog voice (human voice) into data packets then through public internet data networks and private intranet data packets are passed, so that communication can occur. With VoIP communication costs can be reduced so that it can reduce investment costs and conversations (cost saving) or even up to 100% free. VoIP implementation can be done by designing a wireless VoIP network (cable) using 3CXSystemPhone software as a PBX. In this scientific work the software used is 3CXSystemPhone 11.0, where SIP is a VoIP server which is a freeware software, in its application only requires one PC server and several PC clients (2 for example) that are connected to each other

Abstract

The difficulty of finding the desired food and to buy it also one of the problems that almost everyone faces. This problem occurs because the desired item is only sold in a certain place or rare. We need a way to solve the problem. One of them is e-commerce, which mostly uses the internet network. By making a ordering program, customers can see a list of foods sold and can order food from far away and the transaction process becomes safer and easier. Therefore the author conducted a research in a place / business called Ayam Gepuk Pak Gembus Dasana Indah Branch, and the author found several problems in the place like a narrow place to eat, so most people ordered to take home, the storage of data is still manual (storing it in paper) and the owner want to expand their business. So, the author decided to make a booking application for Ayam Gepuk Pak Gembus Dasana Indah Branch to make it easier for customers to order food, and also make the admin page so that the owner can monitor the income from his business, stock items, and view reports. At least the author made the ordering application using the CodeIgniter framework. MVC (Model-View-Controller) CodeIgniter framework that makes coding is divided into three, namely Controller, Model, and Views so that the coding is easy to read by new programmers in the future and there are already codes so programmers don't bother to look for codes.
