Abstract

The purpose of this research is to design a low cost sensor node using ATmega328p microcontroller for monitoring a paddy field condition. Data collection techniques are done by literature study and sensor node prototype evaluation. The designed sensor node in this research consist of ATmega328P as an electronic circuit controller, DHT11 sensor to sense temperature and humidity, soil moisture sensor to read soil moisture parameter, 9V battery as power source of the node, 16MHz clock crystal to increase the microcontroller accuracy, voltage regulator to maintain a constant voltage level, and capacitor for the timer of the circuit. We use the C/C++ Arduino programming language to develop the software side of the node. The evaluation results show that the proposed sensor node is capable of sensing air temperature and humidity, soil moisture as well as send and receive the sensing data to/from the gateway node. The communication distance of the nRF24L01 module that we use for the node without an external antenna is up to 20.65 meters with an average packet loss of 20%.

Abstract

This study aims to develop a sales application that can help the Palopo Shop Rejeki Perkasa Motor process sales data and stock items by applying a sequential linear method so that it can support the sales activities of the store. The stages in this study are divided into five, namely analysis and definition of needs, system design and software, implementation and unit testing, integration and system testing, and operation and repair. To obtain data and information that supports the implementation of this research, an application needs analysis is carried out. System design which includes system modeling is done using DFD (Data Flow Diagram) and data modeling using ERD (Entity Relationship Diagram), then implemented using Visual studio 2013 programming language and mysql as its database.

Abstract

This study aims to determine whether by using the Unified Modeling Language application developers can easily understand the self service system. The method used in this study is the Unified Modeling Language method to produce system modeling in the form of three Unified Modeling Language diagrams (use case diagrams, activity diagrams, and class diagrams) and the test method to produce an average score of 89.75 test respondents' understanding. Based on the research results obtained, it is concluded that the use of the Unified Modeling Language makes it easier for application developers to understand the self service system of the Self Service in Food Menu and Order application so that it can be used as a benchmark if you want to develop Self Service in Food Menu and Order applications in the future.
