Abstract

The service center in a company or agency is a place to serve various kinds of questions and customer complaints served by a customer service. However, it is undeniable that the role of customer service has many shortcomings, such as having to answer repeated questions given to different customers and limited hours. With the rapid development of technology, this role is now supported by an interactive automation system in answering questions given to customers. The automation system in question is a virtual assistant in the form of a chatbot. The application in the chatbot design is built by utilizing text mining reasoning, applying patterns between user input and the database using the Brute Force algorithm, and the process of correcting erroneous words using the Peter Norvig algorithm. Text mining can be defined as the process of extracting the required information from textual sources, the Brute Force algorithm performs a pattern from left to right, and the Peter Norvig method for correcting words by deciphering each letter in the wrong word. The chatbot design is useful in increasing the quality and effectiveness of services at LAZISMU DIY. The chatbot system that was built certainly passed the method validation test process. Testing is done by implementing the black-box testing method. The test results obtained are based on 7 test scenarios with a total of 96 questions, which is 93%.

Abstract

User satisfaction is one of the most important factors for the successful implementation of information systems, including academic information systems in tertiary institutions. The academic information system at the Polytechnic has never been evaluated for user satisfaction, so there may be obstacles in its use. Since the implementation of this academic information system, several problems have been found, such as incorrect grades entered, some functions not running optimally, information is rarely updated, sometimes the server goes down, so the system cannot be used. The problem encountered may be due to an academic information system whose satisfaction factor has never been evaluated based on the end user's perception. As a result, the system does not meet the end user's needs and expectations so they are not very satisfied with using it. The purpose of this study is to measure the quality of academic information systems and determine user satisfaction. The model used in this study is End User Computer Satisfaction (EUCS) which consists of five factors, namely Content, Accuracy, Format, Ease of use, Timeliness as the independent variable and satisfaction as the dependent variable. The sample in this study was 146 respondents consisting of students. Data collection used a closed questionnaire consisting of 13 questions for the five variables studied. The results of this study were obtained based on data analysis carried out using descriptive analysis techniques using a range of categories and percentages via a Likert scale. The results of this study indicate that the level of satisfaction of users of academic information systems at Polytechnics as a whole is included in the agree category. Users feel satisfied using the Polytechnic academic information system, with a percentage value of 76.43%.

Abstract

Piutang adalah instrument yang krusial dan memerlukan perhatian yang serius dalam mengelola sebuah peusahaan. Kinerja suatu perusahaan dapat dipengaruhi oleh besarnya nilai piutang yang dimilikinya. Apabila nilai piutang terlalu besar, maka dapat menjadi ancaman bagi kelangsungan hidup perusahaan. Ketika melakukan penagihan, perusahaan seringkali menghadapi kendala, salah satunya adalah keterlambatan pembayaran. Seperti halnya perguruan tinggi Institut Teknologi dan Bisnis Muhammadiyah Wakatobi (ITBMW) yang menetapkan biaya pendidikan yang wajib dibayarkan oleh mahasiswa dalam jangka waktu tertentu atau dilakukan dengan cara mengangsur. Akan tetapi malah semakin banyak mahasiswa yang menunggak karena masih banyak mahasiswa yang belum membayar biaya pendidikan dan sistem angsuran yang diterapkan. Akibatnya, semakin tinggi jumlah piutang mahasiswa, semakin besar kemungkinan bahwa biaya pendidikan mahasiswa tak tertagih.  Penelitian ini bertujuan untuk memprediksi piutang biaya pendidikan mahasiswa tak tertagih di ITBMW menggunakan metode klasifikasi yaitu algoritma Naïve Bayes. Data yang akan dimanfaatkan terdiri dari informasi mahasiswa ITBMW yang didapatkan dari PDDikti selama periode 2020/2021, 2021/2022, dan 2022/2023 selain itu juga akan digunakan data internal Biro Administrasi Keuangan ITBMW untuk tahun anggaran 2021, 2022 dan 2023. Pengolahan data dilakukan untuk memperoleh hasil prediksi yang optimal dengan mengevaluasi kinerja algoritma sehingga memperoleh hasil yang terbaik. Atribut pendukung yang digunakan pada dataset yang tersedia yaitu: NIM, nama mahasiswa, status, perguruan tinggi, program studi, jenjang, alamat kelurahan/desa, alamt kecamatan, pendidikan wali, pekerjaan wali, penghasilan wali, keterangan, jumlah piutang uang kuliah tunggal (UKT) mahasiswa, umur piutang UKT mahasiswa, jumlah piutang biaya sarana dan prasarana pembangunan (BPP), umur piutang BPP, status piutang, program studi, jenjang studi, alamat, pendidikan ayah/ibu/wali, pekerjaan ayah/ibu/wali, penghasilan ayah/ibu/wali, jumlah piutang UKT, umur piutang UKT, jumlah piutang DPP, dan umur piutang DPP. Target dan sasaran dari pengolahan data ini adalah piutang mahasiswa dengan status tertagih dan tidak tertagih, dengan menggunakan dua percobaan yaitu dengan data proporsi data training dan data testing 80:20 dan 90:10. Dari dua kombinasi percobaan tersebut proporsi data training dan data testing 80:20 menunjukkan tingkat akurasi yang tinggi yaitu 92,31% merupakan tingkat akurasi yang terbaik dibandingkan dengan proporsi 90:10 yang menghasilkan tingkat akurasi 88,46%.
