In Indonesia, the detection of forest and land fires relies on hotspot information captured from satellites. However, the location obtained by the satellite has a horizontal error of 2 km from the ground check data. Therefore, these information are less relevant to the actual location.</p> <p>In this research, an android app is proposed to extract Exchangeable Image Format (EXIF) photo metadata. The metadata has image information such as latitude and longitude, to obtain the location of forest fires reported by the application user. In addition, this research implemented one of the image processing methods to classify fire and smoke in images of fires. Color filtering method is used based on the color space of Red Green Blue (RGB), Hue Saturation Value (HSV) and YCbCr. This classification process aims to ease the burden on the admin in confirming user reports.</p> </td> </tr> </tbody> </table> <p>The results of the fire and smoke classification process are described using a confusion matrix. This matrix produces an accuracy rate of 75%, a precision of 80% and a recall of 80% for a fire classification and an accuracy of 70%, a precision of 92% and a recall of 87% for smoke classification. There are 25% and 30% of misclassified data of fire and smoke. This is because the color filtering method classifies each color pixel from the image, therefore many pixels that are not classified as fire or smoke images are classified because there are other objects that have a range of colors to classify fire and smoke</p> Rizal Endar Wibowo Rony Teguh Ariesta Lestari Copyright (c) 2021 Jurnal Teknologi Informasi: Jurnal Keilmuan dan Aplikasi Bidang Teknik Informatika 2021-01-10 2021-01-10 15 1 1 12 10.47111/jti.v15i1.1934 MENDETEKSI REDUNDANSI PASANGAN KALIMAT DALAM DOKUMEN SPESIFIKASI KEBUTUHAN PERANGKAT LUNAK DENGAN PENDEKATAN KEMIRIPAN SEMANTIK https://e-journal.upr.ac.id/index.php/JTI/article/view/1894 <p>Software Requirements Specification Document must be complete, unambiguous and correct because an incorrect Software Requirements Specification Document can lead to failure in software development. Software Requirements Specification document must contain non-redundant sentences. Meyer's Seven Sins describes several errors in Software Requirements Specification Document, one of which is redundancy which is a variant of noise. Redundancy is the repetition of the same information, but using different terms or phrases, thus giving the impression that new information is available. This study analyzes the performance of the framework and tools for detecting redundancy in sentence pairs in the software requirements specification document using the WordNet-based semantic similarity method. This study tries to develop the framework and tools that have been proposed in previous studies, namely by detecting redundancy in sentence pairs without fact extraction. The proposed approach and evaluation process uses Kappa values ??to determine whether the performance of the framework and assistive tools can be used to detect redundancy in sentence pairs properly.</p> <p>The method using literature study, data collection, problem analysis, making a framework, making auxiliary tools, and testing. The test uses the Kappa value with two scenarios, from the results of testing the framework and assistive tools can be used to detect redundancy in the Software Requirements Specification Document with a Kappa value of 0.777 with the interpretation of the kappa value is a substantial agreement at a threshold of 0.73</p> Enny Dwi Oktaviyani Licantik Licantik Copyright (c) 2021 Jurnal Teknologi Informasi: Jurnal Keilmuan dan Aplikasi Bidang Teknik Informatika 2021-01-10 2021-01-10 15 1 13 24 10.47111/jti.v15i1.1894 OPTIMALISASI KEAMANAN WIRELESS MENGGUNAKAN FILTERING MAC ADDRESS https://e-journal.upr.ac.id/index.php/JTI/article/view/1910 <p>The use 802.11 wireless-based network services have become one of the most widely used network services, this will be directly proportional to the security holes that are in the wireless network. The rise of access rights theft in wireless networks is due to the large number of software and tools available on the internet to read encryption in wireless security. To minimize the occurrence of theft of access rights in wireless networks can use a layered security system by implementing security Hotspot login and MAC Address Filtering. This layered wireless network security is able to block users who try to access the network. This is because the wireless network security system has verified access rights 2 (two) times by matching the username and password in the hotspot login with the physical address or MAC address of the client. From the research results obtained by clients who use a username and password with different devices can not access the computer network. So every client who wants to connect to the internet network must use a device that has registered its MAC Address and in accordance with user access rights and passwords in the Hotspot login</p> Firmansyah Firmansyah Rachmat Adi Purnama Rachmawati Darma Astuti Copyright (c) 2021 Jurnal Teknologi Informasi: Jurnal Keilmuan dan Aplikasi Bidang Teknik Informatika 2021-01-10 2021-01-10 15 1 25 33 10.47111/jti.v15i1.1910 WEBSITE PEMESANAN PENGINAPAN DI PALANGKA RAYA https://e-journal.upr.ac.id/index.php/JTI/article/view/1935 <p>Internet as a means of fast and easy information media for the general public, in this case can also be used to find accommodation in Palangka Raya, Website booking accommodation in Palangka Raya also to facilitate customers in the process of booking a stay where customers can know the availability of room, room facilities and last room price also make it easier for the property to use it as a media information on the The property can manage the accommodation, rooms, room facilities as well as confirmation of orders from customers, then admin tasks as the manager of the website.</p> <p>The method of software development used is the advanced waterfall methodology, namely analysis, design, coding and testing.

Flights were reopened when the government relaxed the PSBB in mid-May 2020. However, aviation activities must comply with health protocols. One of the requirements for traveling by plane is to show a letter of negative PCR test results for COVID-19 or rapid test with non-reactive results. The medical clinical laboratory in registering the rapid test is still manual so that the general public who wants to travel by plane in carrying out a rapid test must be served from registration to completion at the clinic. So that sometimes there is an accumulation of people who want a rapid test. It is necessary to make a registration system for rapid tests in medical clinics using the waterfall method. The stages of system development are business process modeling using Data Flow Diagrams (DFD) and Entity Relationship Diagrams (ERD), user interface design, and the testing process will be carried out with a blackbox. The system developed can reduce the accumulation of patients in the clinic. From the test results, the system functionality can run well</p> Putu Bagus Adidyana Anugrah Putra Copyright (c) 2021 Jurnal Teknologi Informasi: Jurnal Keilmuan dan Aplikasi Bidang Teknik Informatika 2021-01-10 2021-01-10 15 1 44 52 10.47111/jti.v15i1.1959 SISTEM INFORMASI PENDAFTARAN TES TOEFL PADA UPT BAHASA UNIVERSITAS PALANGKA RAYA BERBASIS WEBSITE https://e-journal.upr.ac.id/index.php/JTI/article/view/1958 <p>Information about the TOEFL test at Palangka Raya University is still being carried out manually starting from registration, payment confirmation, announcing when the exam will be held, the TOEFL test process, and graduation announcements.

The use of databases on the geographic information system of residents' lands makes it possible to store, change, and display all data quickly and easily. One of the factors that become a problem in database design is the point of view of seeing data that varies between designers, programmers, and end-users. Therefore we need a methodology in good database design by applying procedures, techniques, tools, and documentation. The method used in this study used the Research and Development (R&amp;D) method, while the database design method used the Database Life Cycle (DBLC) method. The research variables were database design for the geographic information system of resident land with a relational data model. Research aspects include conceptual design, logical design, and physical design. The final result of this research is to produce 10 types of conceptual entities, produce a relationship diagram of the ten logical entities, and produce a physical design consisting of user_admin, user_pengguna, data_desa, data_kecamatan, data_kabupaten, jenis_tanah, data_penduduk, data_buku_c, data_mutasi, and data_sppt tables.</p> Tri Amri Wijaya Constantin Menteng Afis Julianto Adi Surya Ema Utami Copyright (c) 2021 Jurnal Teknologi Informasi: Jurnal Keilmuan dan Aplikasi Bidang Teknik Informatika 2021-01-10 2021-01-10 15 1 72 81 10.47111/jti.v15i1.1867 APLIKASI SENTIMENT MONITORING UNTUK TWITTER DENGAN ALGORITMA NAIVE-BAYES CLASSIFIER https://e-journal.upr.ac.id/index.php/JTI/article/view/1902 <table> <tbody> <tr> <td> <p><em>Every day there are millions of opinion spread across social networks.
