Abstract

The purpose of this article is to present DES encryption on the Raspberry Pi mini pc. This implementation also aims to illustrate that the DES algorithm can be applied with small resources. This research was carried out by an experimental approach, which carried out the implementation process in mini pc hardware and xampp software. The DES algorithm is implemented web-based with PHP programming with the Apache web server using text data. The results of the study, that the DES algorithm can run well with minimum hardware, such as mini pc raspberry with a very fast time in the process, speed in the process and lots of text data from the process. So, the DES algorithm can be widely adopted for various applications from the mini Raspberry PI by producing information that is strong in security and reliability.

Abstract

The need for irrigation is absolute for the agricultural system. Water pump is a highly needed tool by society in providing clean water and irrigation. If we only rely on rainwater, the land becomes unproductive in the dry season. The unavailability of electricity in many locations in Indonesia is an obstacle for farmers to install drilled wells or draw water from rivers. In this research, a solar water pump system is designed that allows it to be moved easily. The solar pump uses a 100 Ah battery, a 120 WP solar panel and a 1000 watt inverter. The model has been tested to irrigate strawberry gardens in Pintubosi Village, Toba Regency. The pump has been running for 4 hours (12.00 – 16.00 AM) while irrigating and charging the battery are running simultaneously.
