Abstract

Abstract:The performance of an agency is very dependent on the data and quality of information obtained, not least in the police agency. The Criminal Investigation Unit (SatResKrim) is one of the most important units in the police force. One form of handling SatResKrim is to manage crime data. Crime data is managed because it contains information to support the investigation process. The information used in the investigation process is included in the crime data, so it is necessary to search for documents of criminal data relevant to the investigation process. Currently, data on SatResKrim unit at East Sector Police Dept. of Yogyakarta Special Region still use Microsoft Excel application, so the process of searching data is still based on text not based on knowledge, consequently if the search keyword is not in accordance with the text contained in the data, then the data is not will appear, if the data does not appear it will slightly hamper the investigation process. From these problems raised the idea to represent police crime data into the form of knowledge as an effort in providing references to the police agencies against the form of development of data processing crime-based semantic ontology. Knowledge of crime data is limited to criminal data by category of theft. Knowledge related to theft criminal data is then stored or represented in an ontology-based semantic model. In representing knowledge using language Ontology Web Language (OWL) and SPARQL as its query. Software used to build systems in this study include protégé 3.5, NetBeans and Jena API as its library. The programming language used is Java Server Page (JSP). Based on the results of research that has been done, by representing crime data into the form of semantic ontology-based knowledge and tested into the form of search-based applications, can generate semantic-based search or search that is able to understand the meaning. It is also supported by test results using recall and precision methods, each of which results in a value of more than 90%. Abstrak:Kinerja suatu instansi sangat bergantung pada data dan mutu informasi yang diperoleh, tak terkecuali pada instansi kepolisian. Satuan Reserse Kriminal (SatResKrim) merupakan salah satu unit terpenting dalam kepolisian. Salah satu bentuk penanganan SatResKrim adalah dengan mengelola data kriminalitas. Data kriminalitas dikelola karena mengandung informasi guna menunjang proses investigasi. Informasi yang digunakan dalam proses investigasi diantaranya terdapat pada data kriminalitas, sehingga diperlukan adanya pencarian terhadap dokumen data kriminalitas yang relevan dengan proses investigasi. Saat ini data yang berada pada unit SatResKrim pada Kepolisian Sektor Depok Timur Daerah Istimewa Yogyakarta masih menggunakan aplikasi Microsoft Excel, sehingga proses pencarian data masih berdasarkan teks bukan berdasarkan pengetahuan, akibatnya apabila kata kunci pencarian tidak sesuai dengan teks yang terdapat pada data, maka data tidak akan muncul, jika data tidak muncul maka akan sedikit menghambat proses investigasi. Dari permasalahan tersebut memunculkan gagasan untuk merepresentasikan data kriminalitas kepolisian kedalam bentuk pengetahuan sebagai upaya dalam memberikan referensi kepada instansi kepolisian terhadap bentuk pengembangan pengolahan data kriminalitas berbasis semantik ontologi. Pengetahuan-pengetahuan mengenai data kriminalitas dibatasi pada data kriminalitas dengan kategori pencurian. Pengetahuan-pengetahuan terkait data kriminalitas pencurian kemudian disimpan atau di representasikan dalam model semantik berbasis ontologi. Dalam merepresentasikan pengetahuan menggunakan bahasa Ontology Web Language (OWL) serta SPARQL sebagai query-nya. Software yang digunakan untuk membangun sistem dalam penelitian ini meliputi protégé 3.5 ,NetBeans serta Jena API sebagai library-nya. Bahasa pemrograman yang digunakan adalah Java Server Page (JSP). Berdasarkan hasil penelitian yang telah dilakukan, dengan merepresentasikan data kriminalitas kedalam bentuk pengetahuan berbasis semantik ontologi dan di ujikan ke dalam bentuk aplikasi berbasis pencarian, dapat menghasilkan pencarian berbasis semantik atau pencarian yang mampu memahami makna. Hal tersebut juga didukung oleh hasil uji dengan menggunakan metode recall dan precision yang masing-masing hasilnya menunjukkan nilai lebih dari 90%.

AbstractIn practicum activities, laboratory assistants input data in the form of minutes, input values, input presences, and report preparation in an excel form. When the assistant wants to see the development of a student, then the assistant must open excel data one by one and look for the student's name or number and then collect the scores from previous meetings starting from the quiz value, assignment value, report value, project value, and response then check whether the student experiences an increase or decrease in the lab. With a large number of students, of course, the assistant will encounter difficulties if you have to find students one by one while the excel data is not small. The solution provided is to create a web-based system as the application of smart labs to monitor the development of student grades in the campus laboratory environment. By using a web-based system, laboratory assistants and lecturers will be facilitated to recapitulate student grades and monitor students as well as input values or calculate the final grades of students. The study uses the Waterfall method as a method of developing systems and research methodologies by conducting observations, interviews, and literature. The results obtained are that the system can display values in the form of a practicum value report that has been calculated using assessment weights and graphs that show the development of values at each meeting with different value categories.Keywords: Information System, Practicum, Smart LabAbstrakPada kegiatan praktikum, asisten laboratorium melakukan penginputan data berupa berita acara, input nilai, input presensi dan pembuatan laporan ke dalam dokumen berupa excel. Ketika asisten ingin melihat perkembangan seorang mahasiswa, maka asisten harus membuka data excel satu persatu dan mencari nama atau nomor mahasiswa tersebut lalu mengumpulkan nilai dari berbagai pertemuan sebelumnya mulai dari nilai kuis, nilai tugas, nilai laporan, nilai projek dan responsi lalu mengecek apakah mahasiswa tersebut mengalami penaikan atau penurunan pada praktikum tersebut. Dengan jumlah mahasiswa yang banyak tentunya asisten akan mengalami kesulitan jika harus mencari mahasiswa satu persatu sementara data excel tidaklah sedikit. Solusi yang diberikan adalah dengan membuat sistem berbasis web sebagai penerapan smart lab untuk memantau perkembangan nilai mahasiswa di lingkungan laboratorium kampus. Dengan menggunakan sistem berbasis web, maka asisten laboratorium dan dosen pengampu akan dimudahkan dalam merekap nilai mahasiswa dan memantau mahasiswa praktikan serta menginput nilai ataupun menghitung nilai akhir dari mahasiswa praktikan. Penelitian menggunakan metode Waterfall sebagai metode pengembangan sistem dan metodologi penelitian dengan melakukan observasi, wawancara dan studi pustaka. Hasil yang didapatkan adalah sistem dapat menampilkan nilai dalam bentuk laporan nilai praktikum yang sudah dihitung menggunakan bobot penilaian dan grafik yang menampilkan perkembangan nilai di setiap pertemuan dengan kategori nilai yang berbeda – beda.Kata Kunci : Sistem Informasi, Praktikum, Smart Lab
