Abstract

The era of globalization is marked by the development of technology and information, this has an impact on the human need for information. PMB(Reception New Students) is a routine college activity at each opening of new teachings. The implementation of PMB is not without questions that has been asked before. By making use of technology information the an FAQ (Frequently Asked Questions) was born which contain answers of the questions that are often asked by people who are need information. To reduce the question repeatedly, then an FAQ answering system was built by applying TF-IDF (Term Frequency - Inverse Document) and the cosine similarity algorithm. TF-IDFweighting is a method for giving weights the relationship of a word (term) to a document is based on two concepts, namely frequency of occurrence of words in a document and frequency inverse documents containing the word. Meanwhile, cosine similarity is a method used to calculate the level of similarity between two objects. This method calculates the similarity between two pieces the object represented in two vectors using keywords of a document as a measure. This study uses 7 data samples from all FAQ data obtained from an interview with Ms. Susilawati, S.Kom. The sample data used will go through a processpreprocessing, TF-IDF weighting, and the cosine similarity method fordetermines the highest level of similarity that will come out as a result end. By using TF-IDF weighting and the cosine similarity method on 7 sample data can get an accuracy rate of up to 64,28%.

Abstract

Guna mendapatkan pelayanan Kesehatan di Pusat Pelayanan Kesehatan masyarakat (Puskesmas) biasanya diawali dengan antrean, antrean merupakan aktivitas menunggu untuk dilayani oleh satu orang atau lebih guna mendapatkan pelayanan yang diinginkan. Pasien yang melakukan kunjungan Puskesmas, biasanya akan mendaftar terlebih dahulu ke loket dan kemudian diberikan nomor antrian manual dan petugas mencatat kedalam buku kunjungan dan buku tersebut sebagai rekam kunjungan sehingga setiap kali kunjungan, staf akan mencari buku pasien dan memastikan apakah pasien terdaftar atau tidak, yang menyebabkan proses pelayanan menghabiskan waktu lebih banyak. Dari permasalahan tersebut maka dilakukan penelitian untuk sistem antrean, antrean dengan memanfaatkan teknologi IoT (Internet of Things) yaitu RFID (Radio Frequency Identification) dengan obkjek e-KTP (electronic Kartu Tanda Penduduk). Pada penelitian dengan menggunakan e-KTP yang di tempelkan pada alat RFID perekaman informasi pengunjung puskesmas cukup satu kali pendataan saja dan untuk kunjungan berikutnya pengunjung tidak perlu dicatat lagi ientitasnya, pengunjung puskesmas hanya mendaftar ke bagian/ poli yang ingin didatangi, seingga dapat memudahkan petugas / staf Puskesmas. Proses identifikasi menggunakan RFID dengan objek e-KTP dapat terjadi dengan menggunakan gelombang elektromagnetik, proses identifikasi RFID membutuhkan dua perangkat yaitu tag dan reader agar dapat berfungsi dengan baik. Penelitian ini menggunakan metode Guidelines for Rapid Application Engineering (GRAPPLE) agar dapat menghasilkan luaran dari sistem ringkas namun tidak mengurangi kualitas sistem yang dibangun. Penelitian ini bertujuan untuk memudahkan pelayanan Puskesmas salah satunya pada proses antrean. Sistem Informasi Pusat Layanan Kesehatan Masyarakat Menggunakan RFID dan objek e-KTP dapat dibuat dan dioperasikan dengan mikrokontroler ESP8266 sebagai pusat kendali rangkaian dan fitur Multi Database yang memudahkan dalam sinkronisasi dengan sistem Rekam Medis, sehingga sistem informasi yang di buat dapat diimplementasikan pada Puskesmas

Abstract

– Streaming is a term for a video or audio file that can be played without first downloading the file. Streaming can also be interpreted as a technique used to transfer data so that it can be processed continuously and continuously. Currently, there are many applications that run audio and video streaming, such as Gnump3d, Spotify, Joox, Deezer and so on. The number of applications does not guarantee the quality of service or good QoS if run on the internet network that passes through many network devices. QoS problems on Audio Streaming media will not be seen much on physical servers but will be seen if the application is installed on a Virtual Private Server. The purpose of this study is to determine the level of service quality or QoS generated by a Gnump3d application installed on a VPS by only paying attention to the parameters of Delay, Jiiter, Packet, Loss and Throughput. The research methodology uses the Network Development Life Cycle (NDLC) methodology. The results of this study obtained that the QoS of audio streaming is considered good based on the TIPHON QoS measurement standard and only one QoS parameter is considered to have failed, namely Jitter because it has a value that does not match the standard.
