The use of computers in the development of Electronic Chart Display and Information System (ECDIS) teaching materials can be used to assist lecturers in learning activities on vocational campuses as well as other materials in the Computer Base Training (CBT) laboratory at the Indonesian Maritime Polytechnic. The CBT laboratory provides learning materials on ship machinery systems and multiple choice questions for learning evaluation. The purpose of this study was to determine the level of effectiveness of the use of ECDIS material learning media software when used computer-based. The method used in this study is a qualitative method by looking at the final grades of students. This software consists of 42 slides of ECDIS material theory, 1 slide of ECDIS material video tutorial, 1 slide of ECDIS material practice, 20 slides of multiple choice evaluation questions, and 1 slide of final grades made using Visual Basic software. The results of the test showed that all cadets who attended the lecture were successful in using the software until the final grade was obtained.

Incremental rotary encoder is a sensor that can be used to measure the degree of rotation in ship steering simulations. To create a ship steering simulation, Visual Basic software was used to simulate the movement of the rudder and ship. Meanwhile, to obtain incremental rotary encoder reading data, serial communication is used via Universal Serial Bus (USB) media bridged by Arduino which is programmed to convert incremental sensor signals into ASCII signals with a bolt rate of 9600 bps. The aim of this research is to test the accuracy level of the incremental rotary encoder sensor in ship steering simulations using Visual Basic software on commercial ships by using the Solas rule that a ship's rudder must comply when rotated from the midship position to the 35 degree port side position followed by the 35 degree position. starboard side and returning to midship, the rudder movement time was less than 28 seconds. Test results in terms of response speed of the incremental rotary encoder sensor are very good, while in terms of accuracy level for one degree of steering rotation, the result is 4.571 on the Arduino IDE serial monitor reading..

Kemajuan teknologi kesehatan yang cepat dan akurat semakin menjadi kebutuhan utama para pengambil keputusan. Rumah sakit, klinik, puskesmas sebagai institusi yang menyimpan begitu banyak data juga membutuhkan pengolahan data yang benar dan tepat sehingga dapat disajikan dalam bentuk laporan. Sedangkan untuk menyimpan arsip rekam medis tradisional membutuhkan lahan yang luas dan rawan terkena dampak bencana alam dan kebakaran. Menurut sudut pandang pasien, dokumen fisik rekam medis seperti kartu medik, rontgen, hasil USG, hasil EKG dan lain-lain juga berisiko hilang atau rusak sehingga menjadi masalah. Dengan metode riset & development Borg and Gall yang dimodifikasi, Metode deskriptif dipergunakan untuk menghimpun kondisi yang ada di lapangan. Metode evaluatif dipergunakan untuk mengevaluasi Sistem Informasi Rekam Medis Pasien di Pelayanan Kesehatan Kota Tegal yang diwujudkan dalam bentuk Aplikasi Implementasi Big Data dengan NIK, melalui evaluasi produk dan proses uji coba tersebut diharapkan dapat diperoleh masukan tentang kelebihan-kelebihan dan kekurangan-kekurangan dari produk tersebut. Dengan dibuatnya aplikasi rekam medis dapat mempermudah kinerja staff puskesmas dan dokter, serta sistem yang lebih efektif dan efisien dan data NIK sudah teritegrasi dengan sistem online.
