Abstract

Peningkatan kualitas siswa praktik kerja industri dibidang komputer yang siap terjun ke lapangan kerja merupakan salah satu mutu dari setiap SMK, salah satunya beberapa Sekolah Menengah Kejuruan (SMK) baik yang Negeri ataupun Swasta selalu mengirimkan siswa nya untuk prakerin (Praktek Kerja Industri) Pada sebuah perusahaan atau institusi selama 3 bulan dengan kerja lapangan dan menghasilkan laporan. Penelitian ini akan merancang aplikasi android prakerin menggunakan monitoring prakerin programming dengan pemantau aktifitas kegiatan siswa terhadap pembimbing DUDI yang akan diketahui informasi oleh guru pembimbing / pihak sekolah. Proses pengujian aplikasi menggunakan ISO 9126 dengan stakeholder dan pengujian efektivitas, efisiensi, usefullness untuk memastikan aplikasi bisa dipakai dan sesuai fungsional oleh sekolah (SMK Kejuruan). Hasil penelitian berupa monitoring prakerin programming yang dapat berdampak pada pemanfaatan bagi guru pembimbing akan laporan kegiatan prakerin. Aplikasi ini setelah diuji untuk aspek kegunaan bernilai 84,35 (kriteria baik), aspek efisiensi bernilai 83,06 (kriteria baik), aspek fungsional mendapatkan nilai 83,05  (kriteria baik), dan aspek reliability 80,96 (kriteria baik), sehingga secara keseluruhan rata-rata 83,05 (kriteria baik).

Abstract

Steganografi adalah salah satu teknik yang paling kuat untuk menyembunyikan keberadaan data rahasia tersembunyi di dalam penutup obyek. Gambar adalah objek penutup paling populer untuk Steganografi dan dalam steganografi gambar kerja ini diadopsi. Menanamkan informasi rahasia di dalam gambar membutuhkan perhitungan yang intensif, dan oleh karena itu, merancang Steganography dalam mempercepat kecepatan perangkat Steganografi. Ini diimplementasikan menggunakan prosesor ARM7TDMI dan GSM 900. Ada beberapa teknik untuk menyembunyikan informasi di dalamnya gambar sampul. Teknik domain spasial memanipulasi nilai bit pixel gambar sampul untuk menanamkan informasi rahasia. Bit rahasia ditulis langsung ke sampul image pixel bytes. Akibatnya, teknik domain spasial sederhana dan mudah diterapkan. The Least Significant Bit (LSB) adalah salah satu techniques utama dalam steganografi citra domain spasial. Dalam penelitian ini, teknik baru steganografi LSB telah diusulkan yang merupakan versi improvisasi teknik LSB satu bit. Ada pun tujuan dari penelitian untuk menyembunyikan pesan teks rahasia kedalam file gambar sehingga pesan rahasia menjadi aman karena sudah disimpan didalam file gambar sehingga menjadikan alternatif pengiriman pesan agar terhindar dari pencurian dan sabotase.

Abstract

Increasing the competence of vocational students to be able to enter the field is the first goal for the quality of every major level school. The supervisory system for monitoring field work practices at the agency is to monitor, control the activities and activities of students where the completion of reports is one of the important requirements in implementing field work practices in research places of companies or agencies, this supervision system effort occurs because most students come from regions which is far from home so that it requires boarding and the number of students who commit fraud by not attending / coming to companies or research institutions, especially when the current pandemic is an excuse for students. In this study using the direct field observation method, interviews with external supervisors, laboratory assistants and students, while the implementation uses the PHP programming language and MySQL database. The results of the student supervision system in implementation activities for 3 months which can have a positive impact on the use of supervising teachers, schools and internship students in completing reports during the pandemic.

Abstract

With the rapid advancement of information technology today, every world of education requires campuses to develop teaching and learning services in their special practicum in the laboratory. Rapid response laboratory services are a form of participation to take part in the implementation of practicum adjusting standard operating procedures (SOP). In this case, the author takes a case study at the Atma Luhur ISB computer laboratory, making a damage report or PC troubleshooting now still in the form of LOG books and manuals, and the processing time is waiting for lecture hours to finish. Thus, a rapid response application process for response and information service laboratories is needed to make it easier for laboratory workers to carry out job descriptions. The method used in designing this rapid response system application is the waterfall model and is run on the Android operating system. The results of the rapid response application in the Atma Luhur ISB laboratory can help smooth practicum in this laboratory, making it easier for the laboratory and to obtain service responses and practicum services more quickly and effectively. This application after being tested for functional aspects by distributing questionnaires to laboratory assistants got an average value of 87.083% (good criteria), so overall it can be concluded that this application can be applied in the Atma Luhur ISB laboratory.
