Abstract

Perkembangan teknologi yang sangat pesat membuat manusia semakin mudah dalam melakukan aktifitasnya sehari-hari contohnya pengiriman pesan via email. Namun dengan perkembangan teknologi juga membuat pengiriman pesan menjadi semakin tidak aman. Oleh karena itu dibutuhkan sebuah teknik untuk mengamankan pesan sehingga tidak terjadi perubahan pesan di tengah jalan oleh pihak ketiga, diantaranya dengan menggunakan kriptografi. Salah satu algoritma dalam kriptografi yang dapat berfungsi untuk mengamankan teks adalah algoritma RSA. Dalam perkembangannya proses RSA memiliki masalah saat melakukan proses dekripsinya, yaitu membutuhkan waktu yang relatif lama sehingga ditambahkan algoritma CRT (Chinese Remainder Theorem) untuk mempercepat waktu dekripsi. Pada penelitian ini mengimplementasikan algoritma RSA-CRT pada pengiriman teks via email. Penelitian ini menggunakan model proses waterfall yang diimplementasikan dengan menggunakan bahasa pemrograman MatLab. Berdasarkan hasil penelitian, algoritma RSA-CRT dapat diimplementasikan pada pengiriman sebuah pesan via email. Pada penelitian ini dapat disimpulkan bahwa kecepatan waktu algoritma RSA-CRT lebih cepat dibandingkan dengan algoritma RSA. Semakin besar parameter nilai n berdampak pada waktu proses dekripsinya begitu juga ukuran teksnya semakin besar.

Abstract

Mahasiswa Fakultas Pertanian Universitas RiauDosen Fakultas Pertanian Universitas RiauJOM FAPERTA VOL. 6 Edisi ! Januari s/d Juni 2019 This study aims to identify the external factors of the P3A group  production unit affecting the  off succes agricultur bisnis of tidal rice fields in Indragiri Hilir Regency and analyze the relationship of external factors of the P3A group as a production unit to support the success of tidal rice farming in Indragiri Hilir Regency. Research has been carried out in Indragiri Hilir Regency. This study condacted from September 2016 - February 2017, using a survey method with descriptive analysis and regression and correlation. The results of this study indicate that the majority of P3A members of tidal lowland rice in Indragiri Hilir Regency have high school education down, male, productive age, have small dependents, have a narrow land area, the majority work on their own land and P3A external factors play a role in increasing the production of lowland rice in Indragiri Hilir Regency only agricultural extension workers. Agricultural extension agents have a significant relationship to the increase in productivity of tidal paddy rice in the P3A group, namely extension activities for P3A members will increase tidal rice production in Indragiri Hilir by 0.153 ton.ha-1.Keywords: Lowland rice, tides, farmer associations

Abstract

Curriculum has strategic values in the era of independent campus. This research aims to construct a curriculum based multiple perspectives tends to learners’ preference and diversity in Islamic Higher Education. It’s a mix-method research. Qualitative methods, using naturalistic design with interactive models, while quantitative methods with cross-sectional surveys to determine the level of stakeholder’s understandings and the result of it. The result found that multiple dimensions leads to an eternal-essential closed to the Oneness of God, creativity, capability. The other one refers to instrument; model, knowledge, organization, sequence, need analysis, purpose, value, and stakeholder. Furthermore, the appropriate one tends to an essential-humanistic technologies curriculum in fulfilling for independent campus recognition.
