They are susceptible to disease. Therefore, this study proposes an expert system model of disease diagnosis in children. We develop expert strategies to meet the needs of alternative diagnostic tools in making decisions and first aid for children suffering from illness. The development of an expert system model for diagnosing children's diseases using forwarding chaining based on If-Then as an inference engine. We chose the forward chaining method because it has a framework for thinking like a doctor's when diagnosing and concluding the disease. We made testing to model by doctors with 35 patients. The test results show that the expert systems model of disease diagnosis in children in this research has to be used as an alternative or comparison diagnostic tool with an accuracy rate of 79%.</p> 2022-08-13T12:05:28+07:00 Copyright (c) 2022 Henderi Henderi, Fahmie Al Khudhorie, Giandari Maulani, Shofiyul Millah, Viola Tashya Devana https://ojs.unpkediri.ac.id/index.php/intensif/article/view/17433 Android-Based Claim System for Electricity Network Customers of PLN Padang Branch 2022-09-28T15:54:49+07:00 Apriade Voutama apriade.voutama@staff.unsika.ac.id Elfina Novalia elfinanovalia@ubpkarawang.ac.id Garno Garno elfinanovalia@ubpkarawang.ac.id <p>The Padang branch of the State Electricity Company (PLN) is a BUMN responsible for the electricity aspect. Complaints about various electricity problems are difficult for customers, so it is necessary to have a system that can be used as a place for protests and increase PLN's loyalty to customers. The Android-based Claim System is a new application developed to be used by customers as a forum for complaints about electrical problems to the Padang branch of PLN. The Claim System is made into two parts: a Website-based System for PLN and an Android-based Claim Application for customers. Application development using the OOP concept uses UML (Unified Modeling Language) diagrams with the PHP MySql and Android programming languages. The test results were carried out using black box testing with the relevant results. The data of 35 respondents from the assessment questionnaire on the claims system obtained results with an Excellent rating of 78%, a Good rating of 21%, and a Bad rating of 2%. From the analysis results, the Claim System supported by this Android-based Client application can help customers complain about electrical problems quickly and easily.</p> 2022-08-13T12:17:13+07:00 Copyright (c) 2022 Apriade Voutama, Elfina Novalia, Garno Garno https://ojs.unpkediri.ac.id/index.php/intensif/article/view/17509 Measuring The Success of E-Learning In Universities Using The Technology Acceptance Model 2022-09-28T15:54:48+07:00 Anton Yudhana eyudhana@ee.uad.ac.id Imam Riadi imam.riadi@is.uad.ac.id Tuska Abe tuska1907048007@webmail.uad.ac.id <p>This study aims to determine the factors of acceptance of e-learning technology in students who use the technology acceptance model, namely perceived usefulness (PU), perceived ease of use (PEOU), an attitude of acceptance of use (ATU), and acceptance (IT) of the e-learning acceptance system.

This research aims to develop a web-based Geographic Information System (Web- GIS) for water quality monitoring in that watershed. The water quality data had been collected from Enviromental Office of Malang District and Malang City. Water quality in this application was determined using the STORET method, comparing water quality data to water quality standards according to Government regulation so that the water quality status at each monitoring point will be known. The total 57 monitoring points are visualized spatially in this application based on the sampling location plotted by Global Positioning System (GPS). The longitude and latitude coordinates of the monitoring location had been converted in GeoJSON using Quantum GIS (QGIS) software. Google Map API key was used to display a sampling location map on the website. Web-GIS application was tested functionally using a black box, compatibility, and usability testing. Based on the testing results, it worked correctly on Chrome, Edge, Mozilla, and Opera browsers for PC/Laptops and also for browsers on Android smartphones version 4 and above. The application could be appropriately used and efficiently based on usability testing results.</p> 2022-08-14T08:33:04+07:00 Copyright (c) 2022 Novita Rosyida, Layta Dinira, Alfi Nur Rusydi, Agung Dwi Saputra, Ginanjar Setiabudi https://ojs.unpkediri.ac.id/index.php/intensif/article/view/17897 Integration of UTAUT 2 and Delone & McLean to Evaluate Acceptance of Video Conference Application 2022-09-28T15:54:48+07:00 Shahnilna Fitrasha Bayastura shahnilnafit@gmail.com Budi Warsito budiwrst2@gmail.com Dinar Mutiara Kusumo Nugraheni dinar.mutiara@live.undip.ac.id <p>This article explores how college students adopt video conferencing software for distance education. This research aims to examine the factors that influence the spread of video conferencing programs in Indonesia. A video conferencing application is a multimedia program that generates audio and visual content to facilitate real-time, two-way communication between its users. Because of COVID-19, classes of all kinds are now being taken online. As a result, more people are turning to tools like video conferencing. Therefore, learning how to access student video conferencing software is crucial. The UTAUT 2 and Delone &amp; McLean models will be integrated into the analysis. A total of 327 people answered the survey. Next, we used the PLS-SEM technique in smart pls 3.0 to analyze the data collected from the respondents. The R-Square value of 26.2% for the retention intent variable and 62.3% for the user satisfaction variable demonstrate that independent variables in the study can explain endogenous variables and that the remaining variance is influenced by factors external to the survey.</p> 2022-08-13T12:46:06+07:00 Copyright (c) 2022 Shahnilna Fitrasha Bayastura, Budi Warsito, 3Dinar Mutiara Kusumo Nugraheni https://ojs.unpkediri.ac.id/index.php/intensif/article/view/17987 Ontology Data Modeling of Indonesian Medicinal Plants and Efficacy 2022-09-28T15:54:48+07:00 Rizky Maulidya Afifa rizkyafifa@apps.ipb.ac.id Wisnu Ananta Kusuma ananta@apps.ipb.ac.id Annisa Annisa annisa@apps.ipb.ac.id <p>People use medicinal plants for as early prevention and treating disease. Medicinal plants must be careful not to cause side effects, so knowledge is needed. Medicinal plant knowledge is stored using an ontology data model. In some ontology studies, there are still shortcomings in managing information, namely the absence of a relationship between scientific terms related to medicinal plants and phrases already known to the public. Hence, it is necessary to have this relationship. In other studies, there is no information related to disease protein, so this research also develops ontologies to enrich knowledge about medicinal plants and their efficacy. Based on the results, the developed ontology test can build a relationship between scientific terms of therapeutic pants and phrases that are known to the public. The public also knows which proteins affect a disease, so public knowledge about medicinal plants is getting wider.</p> 2022-08-13T12:53:44+07:00 Copyright (c) 2022 Rizky Maulidya Afifa, Wisnu Ananta Kusuma, Annisa Annisa https://ojs.unpkediri.ac.id/index.php/intensif/article/view/18104 Information Technology Governance Design in DevOps-Based E-Marketplace Companies Using COBIT 2019 Framework 2022-09-28T15:54:49+07:00 Merryana Lestari 972020011@student.uksw.edu Ade Iriani ade.iriani@uksw.edu Hendry Hendry hendry@uksw.edu <p>The E-Marketplace system is a digital place where sellers and buyers meet virtually, and transactions can be processed safely. E-Marketplace companies are oriented toward consumer-centric products and services and operate and have 24/7 non-stop transaction activities. E-Marketplace system development has become the digital transformation in Information Technology (IT) governance that meets the requirements of a system-based automated control with the application of DevOps principles. This study uses a mixed method approach through questionnaires, interviews, expert judgment, and relevant literature reviews related to the e-Marketplace system and IT governance concepts using the COBIT 2019 framework, which has 11 design factors with 40 IT processes to obtain the most appropriate governance model for e-Marketplace companies. The results were obtained in the form of 6 (six) methods in the IT governance model using the DevOps approach, namely the APO03 – Managed Enterprise Architecture, APO04 – Managed Innovation, BAI04 – Managed Availability and Capacity, BAI06 – Managed IT Changes, BAI11 – Managed Projects, and DSS03 – Managed Problems with a score ≥ 75 and the capability level target is at level 4.</p> 2022-08-13T00:00:00+07:00 Copyright (c) 2022 Merryana Lestari, Ade Iriani, Hendry Hendry https://ojs.unpkediri.ac.id/index.php/intensif/article/view/18141 Similarity Identification Based on Word Trigrams Using Exact String Matching Algorithms 2022-09-28T15:54:48+07:00 Abdul Fadlil fadlil@mti.uad.ac.id Sunardi Sunardi sunardi@mti.uad.ac.id Rezki Ramdhani rezki2008048036@webmail.uad.ac.id <p>Several studies regarding excellent exact string matching algorithms can be used to identify similarity, including the Rabin-Karp, Winnowing, and Horspool Boyer-Moore algorithms. In determining similarities, the Rabin-Karp and Winnowing algorithms use fingerprints, while the Horspool Boyer-Moore algorithm uses a bad-character table. However, previous research focused on identifying similarities using these algorithms based on character n-gram. In contrast, identification based on the word n-gram to determine the similarity based on its linguistic meaning, especially for longer strings, had not been covered yet. Therefore, a word-level trigram was proposed to identify similarities based on the word trigrams using the three algorithms and compare each performance. Based on precision, recall, and running time comparison, the Rabin-Karp algorithm results were 100%, 100%, and 0.19 ms, respectively; the Winnowing algorithm results with the smallest window were 100%, 56%, and 0.18 ms, respectively; and the Horspool algorithm results were 100%, 100%, and 0.06 ms. From these results, it can be concluded that the performance of the Horspool Boyer-Moore algorithm is better in terms of precision, recall, and running time.</p> 2022-08-13T18:06:06+07:00 Copyright (c) 2022 Abdul Fadlil, Sunardi Sunardi, Rezki Ramdhani https://ojs.unpkediri.ac.id/index.php/intensif/article/view/17465 Analysis of A Pieces Framework of A Localhost Web-Based Income Statement EPOSAL Application 2022-09-28T15:54:47+07:00 Dyah Mustikasari Dyah dyahmustika@umpo.ac.id Jamilah Karaman jamilah@umpo.ac.id Adi Fajaryanto Cobantoro adifajaryanto@umpo.ac.id <p>Measuring the quality of a system must be conducted. This is useful for repairing the damage that may be in the system that has been created. One thing that can be measured in a system is to measure the level of satisfaction of a system. Many methods can be used to measure the level of satisfaction, one of which is the PIECES framework method. PIECES framework is a series of activities that measure the level of happiness based on six variables: performance, information, economics, control and security, efficiency, and service. One of the systems that can be analyzed is the system contained in the EPOSAL application. EPOSAL is a localhost web-based application that can be used to create an income statement. The sample in this study was respondents who used this EPOSAL application. The instrument used was a questionnaire. Data analysis was carried out by following the PIECES calculation provisions. After analyzing the data, it is known that for the variables Performance, Economics, Control, and Security and Service, the satisfaction level is at the "Very Satisfied" level. As for the Efficiency, Information, and Efficiency variables, the level of satisfaction is at the "Satisfied" level.</p> 2022-08-31T12:45:16+07:00 Copyright (c) 2022 Dyah Mustikasari Dyah, Jamilah Karaman, Adi Fajaryanto Cobantoro https://ojs.unpkediri.ac.id/index.php/intensif/article/view/18276 Architecture Design Development of e-Learning for Primary School Learning in Madiun City 2022-09-28T15:54:47+07:00 Hani Atun Mumtahana hanimumtahana@unipma.ac.id Ridho Pamungkas ridho.pamungkas@unipma.ac.id <p>Learning quality can be improved by utilizing technology and digital media in teaching and learning.
