Database Management Systems (DBMSs) are the core of management information systems. Thus, detecting security bugs or vulnerabilities of DBMSs is an essential task. In recent years, grey-box fuzzing has been adopted to detect DBMS bugs for its high effectiveness. However, the seed scheduling strategy of existing fuzzing techniques does not consider the seeds’ correctness, which is inefficient in finding vulnerabilities in DBMSs. Moreover, current tools cannot correctly generate SQL statements with nested structures, which limits their effectiveness. This paper proposes a fuzzing solution named Squill to address these challenges. First, we propose correctness-guided mutation to utilize the correctness of seeds as feedback to guide fuzzing. Second, Squill embeds semantics-aware instantiation to correctly fill semantics to SQL statements with nested structures by collecting the context information of AST nodes. We implemented Squill based on Squirrel and evaluated it on three popular DBMSs: MySQL, MariaDB, and OceanBase. In our experiment, Squill explored 29% more paths and found 3.4× more bugs than the existing tool. In total, Squill detected 30 bugs in MySQL, 27 in MariaDB, and 6 in OceanBase. Overall, 19 of the bugs are fixed with 9 CVEs assigned. The results show that Squill outperforms the previous fuzzer in terms of both code coverage and bug discovery.

Custom tailor-made database management systems (DBMS) are an essential asset, especially for embedded systems. The continuously increasing amount of data in automotive systems and the growing network of embedded devices can profit from DBMS. Restrictions in terms of processors, memory, and storage require customizable DBMS that contain only the needed functionality. We present AutoDaMa, a customizable DBMS designed for automotive systems. With AutoDaMa, it is possible to generate tailor-made DBMS for different scenarios, for example, by restricting the storage size of the DBMS or adding security-related features such as asymmetric and symmetric encryption. We demonstrate the feasibility of our approach through applying different tailor-made DBMS versions derived from AutoDaMa in an automotive testing environment. Our experience is that AutoDaMa can dramatically reduce the development effort and can increase reliability using efficient reuse mechanisms.

The control system of the X-ray complex LIA-20 is based on the Tango Controls framework. Data archiving subsystem HDB++ was improved during the work for efficient storage of waveforms. PostgreSQL DBMS support as a storage was added. PostgreSQL extension “pguint” for unsigned numbers support was modified to support the binary transfer mode during this work. Performance testing of the modified “pguint” extension and the new DBMS interface was performed. This solution allowed to significantly increase the performance of HDB++, reduce the amount of data stored in the database, as well as remove restrictions on the size of the stored data.

Databases are an important part of today’s applications where large amounts of data need to be stored, processed, and accessed quickly. One of the important criteria when choosing to use a database technology is its data processing performance. In this paper, some methods for optimizing the database structure and queries were applied on two popular open-source database management systems: MySQL as a relational DBMS, and document-based MySQL as a non-relational DBMS. The main objective of this paper was to conduct a comparative analysis of the impact that the proposed optimization methods have on each specific DBMS when carrying out CRUD (CREATE, READ, UPDATE, DELETE) requests. To perform the analysis and performance evaluation of CRUD operations for different amounts of data, a case study testing architecture based on Java was developed and used to show how the databases’ proposed optimization methods can influence the performance of the application, and to highlight the differences in response time and complexity. The results obtained show the degree to which the proposed optimization methods contributed to the application’s performance improvement in the case of both databases; based on these, a detailed analysis and several conclusions are presented to support a decision for choosing a specific approach.

Abstract The work examines the effectiveness of the replication mechanism of the X production company database. In order to extend the functionality of the computer database of the enterprise, a model of its resource flow was created and an intensional and extensional part was created for a test database based on real enterprise resources. The model has been simplified to 3-rd normal form. The implementation was done in the MySQL database system. Two different operating systems were selected for testing: Windows and Linux. The database management system (DBMS) is working under the GPL license. MySQL DBMS offers many security mechanisms, and to secure the database, system of users permissions to objects have been selected and also an encryption of access passwords for users and connections to servers was used. A replication engine based on the binary log and the model “main server and backup server” was used to create a copy of the enterprise data.

NVMe SSD hugely boosts the I/O speed, with up to GB/s throughput and microsecond-level latency. Unfortunately, DBMS users can often find their high-performanced storage devices tend to deliver less-than-expected or even worse performance when compared to their traditional peers. While many works focus on proposing new DBMS designs to fully exploit NVMe SSDs, few systematically study the symptoms, root causes and possible detection methods of such performance mismatches on existing databases. In this paper, we start with an empirical study where we systematically expose and analyze the performance mismatches on six popular databases via controlled configuration tuning. From the study, we find that all six databases can suffer from performance mismatches. Moreover, we conclude that the root causes can be categorized as databases' unawareness of new storage devices characteristics in I/O size, I/O parallelism and I/O sequentiality. We report 17 mismatches to developers and 15 are confirmed. Additionally, we realize testing all configuration knobs yields low efficiency. Therefore, we propose a fast performance mismatch detection framework and evaluation shows that our framework brings two orders of magnitude speedup than baseline without sacrificing effectiveness.

Information retrieval system is a system that is widely used to retrieve information. This research will discuss how the system finds back the information stored in database tables. Tables in the database are arranged to store all forms of data entered by database users so that later the stored data can be used again. Re-accessing the database's information must go through a mechanism known as a database management system (DBMS). One of the most widely used DBMS is MySQL. By using a DBMS, information and data can be manipulated according to user needs. Data manipulation in the database is done in a special language, namely SQL (Structure Query Language). Mastery of SQL commands is an obligation for database users so that the manipulated data can produce the required information. However, many database users still do not understand how the actual SQL command syntax manages and manipulates data into information. This is, of course, very risky if the solution is not immediately sought because it will hinder the process of retrieving information from the data stored in the database. For this problem to be resolved, it is necessary to design a system that can help database users translate their wishes into SQL command syntax. This paper will discuss how a command in Indonesian can be translated into SQL command syntax. The method used to solve this research problem is rule-based. There are two stages in the main process: the pre-processing stage, which consists of a word tokenization process, and a translation stage, including a keyword grouping process. This keyword grouping process consists of the keyword group analysis phase, table and column analysis, identification of SQL commands, and mapping of SQL commands. From all stages that have been passed and testing of 7 scenarios with ten (10) commands for each scenario, the accuracy is 81.42%. The inaccuracy in the testing process is more a problem of displaying data from two or more tables, for example, using the join table command. This problem can be addressed by adding new rules for the use of table joins.

The importance of information security in general, of managed information at the level of a database has increased with the expansion of the Internet. On the other hand, it has acquired new facets with the increase of the accessibility of the users to as many resources as possible. Large volume of private data in use and the limitation of unauthorized actions to information have brought new aspects to the issue of ensuring their protection. The scope of this field is wide and allows the operation in several directions: identification, description, creation, implementation and testing of mechanisms aimed at improving the working environment in which database management systems operates. Due to the importance of the information managed by a DBMS[1], it is necessary to define a framework safe and easy to use. The database fulfills not only the role of storage, but also of data provider to users. Thus, the information must be protected throughout the interaction process: generation, storage, processing, modification, deletion, etc. Therefore, the security of databases must not only be reduced to the protection of certain data considered sensitive, but also to the creation of a secure, authorized and controlled global environment through which information becomes available to users.

Issues involved in the infologic modeling of the ENDF-format nuclear data libraries for the purpose of converting ENDF files into a relational database have been considered. The transfer to a relational format will make it possible to use standard readily available tools for nuclear data processing which simplify the conversion and operation of this data array. Infological models have been described using formulas of the “Entity (List of Attributes)” type. The proposed infological formulas are based on the physical nature of data and theoretical relations. This eliminates the need for a special notation to be introduced to describe the structure and the content of data, which, in turn, facilitates the use of relational formats in codes and solution of nuclear data evaluation problems. The concept of nuclear informatics has been formulated based on relational DBMS technologies as one of the tools for solving the “big data” problem in modern science and technology. The organizational and technological grounds for the transfer of ENDF libraries to a relational format are presented. Requirements to the nuclear data presentation formats supported by relational DBMS are listed. Peculiarities of the infological model construction, conditioned by the hierarchical nature of nuclear data, are identified. The sequence for the ENDF metadata saving is presented, which can be useful for the verification and validation (testing of the structural and syntactical validity and operability) of both source data and the procedures for the conversion to a relational format. Formulas of infological models are presented for the cross sections file, the secondary neutron energy distributions file, and the nuclear reaction product energy-angle distributions file. A complete array of infological models for ENDF libraries and the generation modules of respective relational tables are available on a public website.

The isolation level Multiversion Read Committed (RC), offered by many database systems, is known to trade consistency for increased transaction throughput. Sometimes, transaction workloads can be safely executed under RC obtaining the perfect isolation of serializability at the lower cost of RC. To identify such cases, we introduce an expressive model of transaction programs to better reason about the serializability of transactional workloads. We develop tractable algorithms to decide whether any possible schedule of a workload executed under RC is serializable (referred to as the robustness problem). Our approach yields robust subsets that are larger than those identified by previous methods. We provide experimental evidence that workloads that are robust against RC can be evaluated faster under RC compared to stronger isolation levels. We discuss techniques for making workloads robust against RC by promoting selective read operations to updates. Depending on the scenario, the performance improvements can be considerable. Robustness testing and safely executing transactions under the lower isolation level RC can therefore provide a direct way to increase transaction throughput without changing DBMS internals.

Sistem Informasi Pengolahan Data Mahasiswa Universitas Muhammdiyah Sumatera Barat,Sistem pengolahan data adalah suatu kesatuan yang saling berhubungan atau terintegrasi untuk membentuk suatu sistem antara data, perangkat keras, perangkat lunak, prosedur pengolahan, dan tenaga pelaksana.Pembuatan sistem ini menggunakan metode blackbox testing karena pengujian yang dilakukan hanya mengamati hasil eksekusi melalui data uji dan memeriksa fungsional dari perangkat lunak. Jadi dianalogikan seperti kita melihat suatu kotak hitam, kita hanya bisa melihat penampilan luarnya saja, tanpa tau ada apa dibalik bungkus hitamnya. Sama seperti pengujian black box, mengevaluasi hanya dari tampilan luarnya (interfacenya), fungsionalitasnya.tanpa mengetahui apa sesungguhnya yang terjadi dalam proses detilnya (hanya mengetahui input dan output).Hasil pembuatan sistem ini menghasilkan sebuah sistem yang mampu mencegah terjadinya duplikasi data serta dapat menampilkan data yang terkait pada setiap individu,dalam pembuatan sistem ini menggunakan framework Admin Lte 2, bahasa pemrograman PHP dan DBMS XAMPP, serta untuk pemogramannya menggunakan aplikasi visual studio code. Pembuatan website ini bertujuan untuk menggantikan system yang semula menggunakan google form, digantikan dengan website pengolahan data yang dapat menampilkan data yang terkait degan setiap individuKata Kunci: Sistem Informasi, Mahasiswa, bahasa pemograman

Selectivity estimation refers to the ability of the SQL query optimizer to estimate the size of the results of a predicate in the query. It is the main calculation based on which the optimizer can select the least expensive plan to execute. While the problem has been known since the mid-1970s, we were surprised that there are no solutions in the literature for the selectivity estimation of inequality joins. By testing four common database systems: Oracle, SQL-Server, PostgreSQL, and MySQL, we found that the open-source systems PostgreSQL and MySQL lack this estimation. Oracle and SQL-Server make fairly accurate estimations, yet their algorithms are secret. This paper, thus, proposes an algorithm for inequality join selectivity estimation. The proposed algorithm was implemented in PostgreSQL and sent as a patch to be included in the next releases. We compared this implementation with the above DBMS for three different data distributions (uniform, normal, and Zipfian) and showed that our algorithm provides extremely accurate estimations (below 0.1% average error), outperforming the other systems by an order of magnitude.

Fund management in financial institutions is a fundamental thing. Baitul Maal Mitra Usaha Mandiri as a microfinance institution plays a role in collecting and distributing donations to those in need. Data recording of receipts and distribution of donations at the Baitul Maal is still done manually where staff enter data into Microsoft Excel and send WhatsApp messages one by one, causing data not to be integrated and allowing for errors such as repeated recording, data loss, or other human errors. This problem has led to the development of a website-based donation management information system that can be accessed online. The system was built to make it easier for staff to manage financial data, make it easier for managers to monitor financial reports, and as an effort to be transparent to the public. The system was developed using the System Development Life Cycle (SDLC) waterfall model. System development is carried out using the Hypertext Preprocessor (PHP) programming language with Laravel framework and MySQL database management system (DBMS). The system was tested using black-box testing and System Usability Scale (SUS). The results of this study are the creation of a website-based Baitul Maal donation management information system that can be used to manage data on receiving and distributing donations and publishing financial reports to the public. The system has been tested using black-box testing and System Usability Scale with a test result of 80.81.

Evaluating students' learning experiences outcomes cannot be considered a simple task. This paper aims at investigating students' overall performance and the discriminating power of particular tests' items in the context of business courses. The purpose of this paper is to contribute with this issue while analyzing it, with scientific approach, from an accounting information systems standpoint: two experiments based on a database management system (DBMS) undergraduate course, involving 66 and 62 students (experiments E1 and E2, respectively). The discriminant analysis generated discriminant functions with high canonical correlations (E1= 0.898 and E2= 0.789). As a result, high percentages of original grouped cases were correctly classified (E1= 98.5% and E2= 95.2%) based on a relatively small number of items: 7 out of 22 items from E1 (multiple-choice), and 3 out of 6 from E2 (short-answer). So, with only a few items from the analyzed instruments it is possible to discriminate "good" or "bad" academic performance, and this is a measure of quality of the observed testing instruments. According to these findings, especially in business area, instructors and institutions, together, are able to analyze and act towards improving their assessment methods, to be of minimum influence while evaluating students' performance.

Geospatial data and information within contemporary land administration systems are fundamental to manage the territory adequately. 3D land administration systems, often addressed as 3D cadastre, promise several benefits, particularly in managing today’s complex built environment, but these are currently still non-existent in their full capacity. The development of any complex information and administration system, such as a land administration system, is time-consuming and costly, particularly during the phase of evaluation and testing. In this regard, the process of implementing such systems may benefit from using synthetic data. In this study, the method for simulating the 3D cadastral dataset is presented and discussed. The dataset is generated using a procedural modelling method, referenced to real cadastral data for the Slovenian territory and stored in a spatial database management system (DBMS) that supports storage of 3D spatial data. Spatial queries, related to 3D cadastral data management, are used to evaluate the database performance and storage characteristics, and 3D visualisation options. The results of the study show that the method is feasible for the simulation of large-scale 3D cadastral datasets. Using the developed spatial queries and their performance analysis, we demonstrate the importance of the simulated dataset for developing efficient 3D cadastral data management processes.

Health agency service indicators are used to determine the level of utilization, quality, and efficiency of health agency services. The measurement of service indicators is determined by applying the correct IPRI (Indicator of Inpatient Service) method/formula. Based on the results of observations in the Medical Record unit of the Berbah Public Health Center, Sleman Yogyakarta, it was found that the delay in returning the daily inpatient census sheets affected the value of each service indicator. In addition, inaccuracy in calculating the daily inpatient census data recapitulation resulted in inaccurate data. Therefore, a computer-based inpatient service indicator measurement system is needed in order to produce a faster and more accurate value for each service indicator in inpatient services. The stages of the research carried out adopted the stages in the SDLC Waterfall method, including the first stage of communication (project initiation & requirement gathering). The second stage is planning (estimating, scheduling, tracking). The third stage of modeling (analysis & design). The fourth stage of construction (code & test). The last stage, deployment (delivery, support, feedback). The application of the IPRI method/formula in PHP coding and supported by MySQL DBMS storage is part of the construction phase which is combined with testing using the black box test and alpha test methods. The goal has been achieved with the establishment of the Service Indicator Measurement System Application based on IPRI in inpatient services at the Berbah Health Center, Sleman Yogyakarta. The system is categorized as good and feasible to use based on the results of black box testing of 84.62% true. Alpha testing obtained a very high level of acceptance (approved) of 100%. The use of this application is proven to be able to produce IPRI calculations quickly and accurately so as to improve the quality of inpatient services, especially related to the daily census, so that leaders can make decisions faster.

Professional certification is an effort to recognize a person's competence by the required work competency standards. Bung Hatta University Professional Certification Institute (LSP) is an agency implementing competency certification activities that have received a license from the National Professional Certification Agency (BNSP) to certify students from various fields of science and professions at Bung Hatta University. Bung Hatta University LSP has the status of the first party LSP educational institutions. The registration process for certification at the Bung Hatta University LSP is still done manually by filling in several paper forms. This is considered ineffective considering the current technological advances. By developing a website-based information system, this can be overcome. The purpose of designing a website-based information system is to produce an information system that can assist the certification process and can be accessed by any relevant user anytime and anywhere. This information system was developed using the waterfall method. This method has several stages, namely the needs analysis, design, implementation, and testing stage. The design of this information system used Unified Modeling Language (UML) and implemented using the Yii2 framework as a PHP framework and MySQL as a Database Management System (DBMS). The design of this information system resulted in a web-based Information System for Bung Hatta University LSP, which focused on the initial administrative process.

The paper is devoted to the development of an expert system for the diagnosis of postcoid syndrome. The introduction provides basic concepts and definitions related to expert diagnostic systems. An analytical review of them is given. Due to the lack of knowledge of the problem of postcovid syndrome in the work, much attention is paid to substantiating the relevance of the issue under consideration. Based on the analysis of the considered expert diagnostic systems, it was concluded that the problem is poorly studied and its further consideration is relevant. The proposed solution provides the main functions and capabilities of the system being developed, the structural diagram of the expert diagnostic system and the description of the system architecture, provides a physical model, and describes the developed knowledge base in sufficient detail. On the basis of the developed rules of the postcovid syndrome, the rules for their scoring are formulated. When calculating the final assessment of the likelihood of diagnosis of postcovid syndrome, the likelihood of influencing the diagnosis of chronic diseases in diagnosed patients was taken into account. The calculation algorithm is described in detail. The system for diagnosing the postcovid syndrome was developed using the C# programming language, Visual Studio 2019, and implemented under the Windows OS. The data storage layer in the system is built on the basis of a modern relational DBMS - MySQL. The paper describes in detail the procedure for working with the system and the procedure for editing it. When describing the testing of the proposed diagnostic system, it is stated that the diagnostic system has passed the testing of all functions; examples of changing the rule base and editing the system are given. In conclusion, it is argued that the diagnostic system proposed by the authors will help medical specialists in determining the postcovid syndrome in patients; in particular, it helps to increase the clarity, reliability of the diagnosis and reduce the time for diagnosis.

Natural Language Interface to Database (NLIDB) translates human utterances into SQL queries and enables database interactions for non-expert users. Recently, neural network models have become a major approach to implementing NLIDB. However, neural NLIDB faces challenges due to variations in natural language and database schema design. For instance, one user intent or database conceptual model can be expressed in various forms. However, existing benchmarks, using hold-out datasets, cannot provide thorough understanding of how good neural NLIDBs really are in real-world situations and its robustness against such variations. A key difficulty is to annotate SQL queries for inputs under real-world variations, requiring considerable manual effort and expert knowledge. To systematically assess the robustness of neural NLIDBs without extensive manual effort, we propose MT-Teql, a unified framework to benchmark NLIDBs against real-world language and schema variations. Inspired by recent advances in DBMS metamorphic testing, MT-Teql implements semantics-preserving transformations on utterances and database schemas to generate their variants. NLIDBs can thus be examined for robustness utilizing utterances/schemas and their variants without requiring manual intervention. We benchmarked nine neural NLIDBs using 62,430 inputs and identified 15,433 defects. We analyzed potential root causes of defects and conducted a user study to show how MT-Teql can assist developers to systematically assess NLIDBs. We further show that the transformed (error-triggering) inputs can be used to augment popular NLIDBs and eliminate 46.5%(±5.0%) errors made by them without compromising their accuracy on standard benchmarks. We summarize lessons from this study that can provide insights to select and design NLIDBs that fit particular usage scenarios.

Badan Pemberdayaan Masyarakat dan Keluarga Berencana (BPMKB) Kota Bogor setiap tahunnya melaksanakan lomba kinerja kelurahan melalui proses perlombaan kelurahan, yaitu untuk mengevaluasi tingkat keberhasilan pembangunan dikelurahan dengan kriteria-kriteria tertentu dalam penyeleksiannya. Berdasarkan hasil wawancara dan observasi lapangan penyelenggaraan perlombaan dilakukan melalui tiga jenis seleksi yaitu seleksi administrasi, seleksi presentasi (ekspos) dan seleksi kunjungan lapang dengan mengacu pada Peraturan Menteri Dalam Negeri nomor 13 tahun 2007 tentang penyelenggaraan perlombaan desa dan kelurahan. Untuk seleksi administrasi sudah ada aturan dan sistem tersendiri untuk menghitung hasil skor penilaian, sedangkan dalam penentuan penetapan pemenang lomba kinerja kelurahan dinilai pada seleksi presentasi dan kunjungan lapang masih menghitung secara manual sehingga dibutuhkan Sistem pendukung Keputusan (SPK) yang mampu memberikan solusi alternatif untuk penilaian presentasi dan kunjungan lapang. Metode yang digunakan dalam sistem pendukung keputusan lomba kinerja kelurahan menggunakan metode Analytical Hierarchy Process (AHP) untuk pembobotan kriteria dan alternatif. Perancangan SPK lomba kinerja menggunakan Model SDLC. Model SDLC terdiri atas perencanaan, analisis, perancangan, implementasi, pengujian, dan pemeliharaan. SPK menggunakan 3 jenis hak akses (roles) yaitu admin, juri dan pimpinan. Keluaran sistem disajikan dalam bentuk hasil angka perhitungan AHP yang dapat dipertimbangkan lebih lanjut oleh pihak pengambil keputusan. Sistem pendukung keputusan dibangun menggunakan Database Managament System (DBMS) MySQL Xampp dan bahasa pemrograman PHP. Pengujian sistem menggunakan Black-Box Testing. Berdasarkan hasil perhitungan diperoleh hasil perhitungan bobot kriteria yaitu : 0,1667 untuk kriteria penguasaan materi ekspos, 0,0556 untuk kriteria penampilan pemberi materi ekspos, 0,1111 untuk kriteria ketepatan waktu ekspos, 0,2222 untuk kriteria produk unggulan, dan 0,4444 untuk kriteria inovasi , sedangkan hasil perhitungan alternatif urutan ranking terbaik yaitu kelurahan Menteng, kelurahan Cibadak, kelurahan Ciparigi, kelurahan Katulampa, kelurahan Cikaret, dan kelurahan Babakan Pasar.

Meningkatnya jumlah kendaraan bermotor memunculkan masalah kemacaten khususnya di perkotaan termasuk Kota Pontianak. Dari sisi pengendara kendaraan bermotor pasti pernah mengalami masalah saat berkendara seperti kehabisan bensin, ban bocor, mogok, kerusakan kendaraan dan sebagainya. Saat mengalami masalah di jalan, misalnya kehabisan bensin atau ban bocor, maka pengendara sangat memerlukan informasi dimana lokasi pom bensin dan bengkel. Jika masalah tersebut terjadi pada malam hari dimana pom bensin dan bengkel sudah tutup maka pengendara memerlukan informasi kios bensin eceran atau bengkel yang masih buka untuk mendapatkan bantuan. Untuk membantu mengatasi masalah yang dihadapi pengendara maka dibangunlah sistem informasi geografis persebaran bengkel, tambal ban dan minyak eceran di Kota Pontianak yang dapat memberikan petunjuk arah jalan serta informasi yang berguna bagi pengendara. Sistem yang dibangun ini sangat penting mengingat data bengkel kecil, kios tambal ban, dan kios bensin eceran belum tersedia atau belum dikelola oleh Google yang selalu menjadi sumber untuk mencari informasi. Sistem ini didesain untuk memudahkan pihak pengguna (pengendara) mencari lokasi layanan terdekat dengan lokasi/posisi keberadaannya dengan menerapkan layanan berbasis lokasi (location based service/LBS) yang disediakan Google Maps. Data lokasi layanan (bengkel, tambal ban, dan minyak eceran) diperoleh dari hasil survey lapangan dan dikelola menggunakan DBMS MySQL. Dengan LBS dan Haversin Formula sistem dapat menghitung jarak radius serta menampilkan lokasi layanan terdekat dan rute perjalanan ( google direction) menuju lokasi layanan tersebut. Berdasarkan hasil pengujian black box testing dengan menggunakan nilai jarak radius tetap (default) maupun nilai jarak radius yang ditentukan oleh pengguna, sistem mampu menunjukkan lokasi layanan tersebut. Sementara berdasarkan pengujian user acceptance test (UAT) dengan menggunakan metode kuesioner skala likert diperoleh nilai rata-rata 83,4%, yang menunjukan bahwa aplikasi mudah untuk digunakan.Kata kunci: sistem informasi geografis, bengkel, tambal ban, minyak eceran, petunjuk arah, skala likert.

Abstrak: Sekolah Menengah Kejuruan masih menjadi favorit para siswa dalam menimba ilmu pengetahuan dibangku sekolah, salah satu yang menjadi alasannya adalah biaya yang terjangkau. Hal ini dibuktikan dengan semakin bertambahnya siswa SMK yang ada pada kota Bekasi sehingga pihak sekolah membutuhkan peningkatan pelayanan yang cepat tanggap yang didukung dengan teknologi informasi, ruang belajar yang nyaman dan pendidik yang profesional. Seiring dengan bertambahnya jumlah siswa membuat pihak sekolah kesulitan dalam mengelola data siswa yang mendaftar secara akurat sampai dengan proses pembuatan laporan yang membutuhkan waktu yang lama. Pada saat penerimaan siswa baru pihak sekolah masih menggunakan sistem manual yakni calon siswa mengisi kertas formulir yang diberikan panitia pendaftaran. Berdasarkan permasalahan yang dihadapi maka tujuan dari penelitian ini adalah membantu pihak sekolah mengelola data siswa dalam proses penerimaan siswa baru menggunakan website yang mana dapat diakses melalui smartphone sehingga kegiatan penerimaan dapat berjalan dengan efektif. Metode yang digunakan pada penelitian ini adalah metode Waterfall karena dianggap memiliki tahapan yang terurut atau sekuensial yaitu analisis kebutuhan, desain, pengkodean, pengujian dan pemeliharaan. Sedangkan bahasa pemrograman untuk membangun sistem menggunakan PHP dengan CodeIgniter web framework, karena dianggap dapat mempermudah dan mempercepat proses pembangunan aplikasi yang memiliki banyak library dan DBMS yang digunakan menggunakan mysql yang kompatibel dalam pembangunan aplikasi berbasis website. Hasil penelitian ini berupa sistem informasi penerimaan siswa baru berbasis web menggunakan framework codeigniter sehingga dapat membantu mempermudah siswa dalam mendaftar dan pihak sekolah dalam melakukan kegiatan penerimaan siswa baru secara online. Kata kunci: penerimaan siswa baru, sistem informasi, metode waterfall Abstract: Vocational High School is still a favorite of students in studying at school, one of the reasons is the affordable cost. This is evidenced by the increasing number of vocational students in the city of Bekasi so that the school needs an increase in responsive services that are supported by information technology, comfortable learning spaces and professional educators. As the number of students increases, it is difficult for schools to manage the data of students who register accurately up to the process of making reports that require a long time. At the time of admission of new students the school still uses a manual system where the prospective student fills out the paper form provided by the registration committee. Based on the problems faced, the purpose of this study is to help the school manage student data in the process of admitting new students using a website which can be accessed via a smartphone so that the reception activity can run effectively. The method used in this study is the Waterfall method because it is considered to have sequential or sequential stages namely requirements analysis, design, coding, testing and maintenance. While the programming language for building systems using PHP with CodeIgniter web framework, because it is considered to be able to simplify and accelerate the process of building applications that have lots of libraries and DBMS that are used using mysql that are compatible in building website-based applications. The results of this study in the form of a web-based new student admission information system using a codeigniter framework so that it can help facilitate students in registering and the school in conducting new student admission activities online. Keywords: new student admissions, information systems, waterfall methods
