ABSTRACT<br />Background of research is human errors in manual data recording, less accurate and data<br />searching requires several time, thus cause difficulties in traceability system, while traceability is<br />to collect product history from receipt of raw materials, processing, packaging until product<br />delivery to customer. The purpose of this research is to design, and develop information system in<br />fish processing to assist traceability of seafood product from receiving, processing until shipping<br />to customer. System have feature to print QR Code label to put in products, which is readability<br />through label scanning, in packaging stage and product shipments. Information label consist of<br />product information,, species type, grade, and weight, supplier information, processing date, and<br />fishing location. System design consist of feasibility study, data collection, system analysis,<br />system design, and development, testing and implementation. Through the summary transaction<br />module, fish processing can be traced from the beginning, starting from the stage of receiving,<br />cutting, retouching to packaging. The QR code stores information where input data is faster<br />through scanning. The use of internal lot codes, makes it easier to trace fish resources at each<br />stage of fish processing, which consists of the code of the fish catch area, supplier code, and fish<br />processing date.<br />Keywords: Traceability, QR Code, Data Management, Information System<br />ABSTRAK<br />Latar belakang penelitian ini adalah banyaknya kesalahan dalam input data manual,<br />ketidakakuratan dan pencarian data yang memerlukan waktu yang lama, kesulitan dalam sistem<br />penelusuran dimana penelusuran sebagai kegiatan mengumpulkan data riwayat produk dari<br />penerimaan bahan baku, pengolahan, pengemasan sampai pengiriman ke pelanggan.Tujuan<br />penelitian ini adalah untuk merancang, dan membangun sistem informasi pengolahan ikan untuk<br />membantu penelusuran produk perikanan dari awal sampai akhir. Sistem menyediakan fitur untuk<br />print label QR Code untuk ditempel pada kemasan produk yang dapat dibaca oleh alat pemindai<br />dalam pengemasan maupun pengiriman produk. Informasi label terdiri dari informasi produk,<br />jenis spesies ikan, jenis, grade dan berat, informasi pemasok, tanggal pengolahan dan lokasi<br />penangkapan ikan. Perancangan terdiri dari studi pendahuluan, pengumpulan data, analisa sistem,<br />perancangan sistem dan pengujian dan implementasi sistem. Melalui modul summary transaction,<br />dapat di telusuri pengolahan ikan dari awal mulai dari tahap penerimaan, pemotongan, retouching<br />sampai pengemasan. Kode QR menyimpan informasi sebagai kode untuk scanning tahap<br />pengolahan lanjutan, proses penginputan data lebih cepat melalui pemindaian maka data ikan<br />sudah otomatis tercatat pada sistem. Penggunaan kode internal lot, memudahkan dalam<br />melakukan penelusuran sumber ikan pada setiap tahap pengolahan ikan, yang terdiri dari kode<br />wilayah tangkapan ikan, kode supplier, dan tanggal pemrosesan ikan.<br />Kata Kunci: Penelusuran, QR Code, Manajemen Data, Sistem Informasi

Rapid technological developments provide benefits for library management. One of them is the application of automatic identifiers in library management, through RFID and QR Code implementation. Some problems that are faced by libraries at the moment, include the lack of guarantees for the safety management of books in the library, lack of services human resources library management, and book availability information has not been accurate. This research conducts the development of a library management information system to solve the problems by using automatic identifiers utilizing Near Field Communication and QR Code technology. The implementation scenario is each library member has the NFC Card and their personal information stored in the NFC card, also each book in the library is put with a QR Code label containing book code information. Transaction of book loan and book return are done by initially tapping NFC Card to record visitor returned or borrow the book and then continue to scanning QR Code label of each book borrowed or returned. In the final stage, the application tested by tapping the NFC card (RFID) on the reader/writer device, and it found the NFC Card could be read or record data from the device at a maximum of 7 cm, while testing phase conducted QR Code label could be read at a maximum distance of 40 centimeters from the device. Implementing automatic identifier help to manage transaction in library more accurate, improve services and provide added value for the library.

In accordance with the assessment of KI-3 and KI-4 on mathematics subjects still have problems in understanding the concept of student learning so that it affects the learning outcomes. With these constraints, in this study researchers combined scientific approaches with learning videos. The design used in this study uses an experimental experimental design called True experimental design, namely the Posttest Only Control Design. The material given at the time of the research action includes the material Limit Functions, Derivatives, and Integral. Through the steps of the research that has been carried out, the final test results are obtained in the experimental class 45% of students belong to a category with very good concept comprehension ability, and 2.5% of students included in the concept comprehension ability category are still lacking in Limit Function material. Then in the material the percentage derivative in the very good category is 50% and the sufficient category is 5%. In Integral material, 50% of students are in the very good category and 50% are in the good category.
