Abstract

Current technological developments are very influential on the process of data distribution that is demanded fast because every second of information can change. One of the methods used in data exchange is to use data replication in a distributed database. The speed of the process and the number of rows that can be replicated in units of time are some of the things that can be taken into consideration when trying to determine how to replicate data in a distributed database.In replication, a software is used to find or more precisely track changes that occur in a database. After changes in one database are identified and known, then changes are made so that all databases are the same as other databases.This study implements two computers consisting of master and slave, each of which is a database server that is connected to each other in the network. The test results obtained in this study are that with the database replication, every data that is stored periodically always backups the slave computer.Keywords—Replication, Database, Distributed Database DOI : 10.5281/zenodo.1493829

Abstract

The hydroponic plant is the technique of cultivating plants (fruits, vegetables, and flowers) by utilizing water and not using soil as a planting medium. Internet of Things (IoT) is the communication between one device and another with the help of software through the internet network. The one method for controlling IoT is using Fuzzy Tsukamoto. The Tsukamoto method is an extension of monotonous reasoning.In Tsukamoto's method, each consequence of  If-Then form rule must be represented by a fuzzy compilation with an affiliation function. The advantages of Fuzzy Tsukamoto system are the mathematical concepts that underlie fuzzy reasoning is very simple and easy to understand. In applying  Fuzzy Tsukamoto in the determination of control and monitoring of hydroponic plants in real-time-based, it functions very efficiently and simplifies work. Keywords—Hydroponic Plants, IoT, Fuzzy Tsukamoto.DOI : 10.5281/zenodo.2781533

Abstract

Kelembaban memegang peranan penting dalam proses dekomposisi pupuk sehingga kelembaban ideal harus dijaga pada kisaran 40% hingga 60% sedangkan suhu pupuk pada kisaran 30°C hingga 60°C. Masalah yang sering terjadi dalam pembuatan pupuk kompos adalah tingkat kematangan pupuk yang belum sempurna yang disebabkan oleh tingkat kelembaban dan suhu dalam proses pembuatan tidak stabil. Umumnya pemantauan suhu dan kelembaban pada proses dekomposisi dilakukan secara manual yaitu dengan mengikuti kebiasaan para petani pupuk sehingga waktu dan kinerja tidak efisien. Namun dengan menggunakan komponen mikrokontroler berbasis android pada proses dekomposisi pupuk dapat memberikan kemudahan untuk memperoleh nilai suhu dan kelembaban pupuk kompos secara lebih akurat. Sensor DHT22 digunakan untuk mengukur suhu dan kelembaban sedangkan NodeMcu ESP8266 sebagai mikrokontroler board untuk mengolah data yang didapatkan dari sensor. Dengan implementasi perangkat lunak menggunakan framework ionic untuk smartphone android, dan arduino untuk mikrokontroler. Proses monitoring suhu dan kelembaban pupuk yang menerapkan monitoring realtime dapat berjalan dengan baik melalui internet dengan latency yang sangat kecil.Kata kunci; Monitoring, Dekomposisi, Mikrokontroler, Realtime, Android
