One of the factors causing the lack of agricultural productivity in Indonesia is the majority of farmers in Indonesia still rely on climate change in the processing of agricultural land. The Design of Automatic Plant Sprinklers Control Devices Using Soil Humidity Sensor in the Agricultural Area was created aimed at helping farmers in Indonesia to manage agricultural land without the need to manually water and see weather conditions. How it works This tool is by using Arduino as a brain movement tool and Soil Moisture Sensor to retrieve data from plants. Then the data that has been obtained by the tool will be sent to the web-based monitoring system using Ethernet Shield. The experimental results and implementation in the field shows that this prototype or prototype can work according to its function and purpose.

Abstract

The Decision Support System (DSS) of SMA major which had been tested in Banten was a system obtained from the former research, as it was expected to help private schools in Banten for students' major. This system has been developed through Fuzzy Tsukamoto's method in obtaining students' major. Fuzzy Tsukamoto requires three determinant factors, namely: skill, interest and aptitude. Fuzzyfication is carried out to get a firmed score of IPA and IPS. After the two scores are obtained, the comparison of those highest scores is conducted to determine the recommendation. In the process of manual data testing, Fuzzy Tsukamoto can be applied in students' major in Banten, with 98% of its accuracy level. After manual testing, Decision Support System of SMA major is designed by using Research and Development (R & D) as its developing system and by Unified Modeling Language (UML) as its designing analysis. The objective of this research aims at measuring the quality testing process of the application that is based on the aspects of functionality, reliability, usability, dan efficiency testingby employing the black box method. Based on the measurement Black Box Method, the Decision Support System of SMA major gets very goodvield, as it can be applied to be as SMA major recommendation in Banten.

Course Scheduling is a routine activity at a college and it is a very important activity for the implementation of condusive academic activities. Problems that often occur in course scheduling are the length of the schedule making process and the clashes due to the many rules that must be considered. This problem happened in Indonesian Computer University at accounting major because the lecture scheduling process was still done conventionally. Given the importance of this scheduling process, optimization steps are needed so that the scheduling process will be faster and the schedule clashes can be minimized. Based on the problems, this research purpose is to optimize course scheduling application using genetic algorithm. The system approach method used in the development of course scheduling applications is object-oriented approach, with system development methods namely prototype models. to build the application we use the Java SE programming language with MySQL database. The conclusion of this study is that the implementation of genetic algorithms to course scheduling applications is able to achieve 0 (zero) clash which means very optimal, and view by time the result is very fast with an average of 1.003 seconds from 10 times the schedule creation attempt.

Komparatif Performance Model Keamanan Menggunakan Metode Algoritma AES 256 bit dan RSA

Along with the rapid development of information technology, the ability to access and provide information to users is getting quicker and more accurate, Therefore, protecting those from any unauthorized access is very important. Cryptography can be use as they’re one of the fields of information technology development to secure data or messages that are personal and confidential. So, it takes a security to prevent things that are not desired. In this case, the message sending process will be encrypted (plaintext to ciphertext) and the recipient of the message will need to be decrypted (ciphertext to plaintext). The algorithm that we will be using are 256-bit American Encryption Standard (AES) symmetric encryption and RSA asymmetric encryption. Performance testing (size and time-process), integrity ("data integrity"), confidentiality, and "non-repudiation" of data or message security with the algorithm method above will refer to 4 (four) modern cryptographic objectives developed. Those algorithm will be used to encode data stored in document files and implementing it using Python 3.0 language and some support applications. And the results of the process of designing and testing data (text and images) obtained did not experience significant growth, but the encryption / decryption of the RSA algorithm method is much slower than the performance of the AES algorithm time-processing method

Aplikasi Info Pariwisata Kabupaten Solok Selatan Berbasis Android

Solok Selatan Regency is a Regency in the eastern part of the province of West Sumatra. In the County many interesting attractions to visit. As nature tourism, cultural tourism, historical tourism, culinary tourism, and lodging. There has been no use of the android technology to publish existing tourism in Solok Selatan Regency, so information on tourism objects do not meet the attraction of tourists. Tourism android-based applications are used to facilitate tourists in exposing and searching for tourism information in Solok Selatan District. This application can be used as a medium of information at once media Solok Selatan District tourism promotion. This application using GPS on Smartphones to find out the location of the user application and instructions the way to tourist sites through the Google Map. There is a menu to share sights form images to a variety of social media or tools provided on the smartphone, as well as the rating menu to perform the assessment of the tourism objects in the form of the input value rating.
