Abstract

Rice is the primary food commodity in Indonesia. To increase the rice production, urea fertilizer has been excessively used, specifically on marginal land. However, it has no desired effect on the plant’s Nitrogen uptake due to volatilization. Previous studies suggest the use of zeolite to be mixed with urea to reduce the volatilization rate. This study aimed to determine the effect of six NP-SR (Nitrogen Phosphorus Slow Release) fertilizer compositions (without NP-SR; 20.69-0; 19.7-5; 17.27-10; 15.9-15; and 18.94-20) on soil chemical properties, nitrogen efficiency, and paddy rice yield on Ultisols at three waterlogging levels (0.5 cm, 3 cm, and 5 cm). The study was an experiment arranged in a Randomized Complete Block Design (RCBD) consisting of two factors, which were waterlogging levels and NP-SR fertilizer compositions. The results showed that waterlogging treatments significantly affected soil chemical properties in the initial vegetative and harvest phases. It can be concluded that the treatment of flooding (up to 3 cm) and fertilizer (NP-SR of 15.90-15) application could significantly reduce the volatilization rate, increase the efficiency of N fertilizer, and increase rice yield.

Abstract

The case of motor vehicle theft is not a new case for the Indonesian National Police (POLRI). The number of cases of motor vehicle theft is also due to the easy plot of burglars in breaking the safety system on motor vehicles. In addition, the condition is caused by various factors such as environmental security, owner's negligence and the vehicle's own security system. For that reason, it is necessary to activate the Arduino Mega 2560 Motor Based Activation Lock Controller, a device capable of preventing and reducing the theft of motor vehicles using RFID technology, password keypad, GSM module and voice signaling. Arduino Mega 2560 Arduino Mega 2560 Arduino Mega 2560, RFID, password keypad, GSM Module Enabled Key Device Turned into a good running system. RFID functions to read IDs from RFID tags that function to activate security first and keypad function to enter password and activate second security and relay electrical of motor. When there is a thief who pushes the stater button directly without doing a tag and enter a password, then the motor will immediately issue a horn and send an SMS to the phone number of the owner of the vehicle. So the owner does not have to worry about theft. Kasus pencurian kendaraan bermotor bukanlah kasus yang baru bagi Kepolisian Republik Indonesia (POLRI). Banyaknya kasus pencurian kendaraan sepeda motor juga disebabkan mudahnya komplotan pencuri dalam membobol sistem pengaman pada kendaraan bermotor. Selain itu kondisi tersebut disebabkan oleh berbagai macam faktor seperti keamanan lingkungan, kelalaian pemilik dan sistem pengaman kendaraan itu sendiri.Untuk itu, dibutukanlah Pengaman Pengaktifan Kunci Kontak Motor Berbasis Arduino Mega 2560, suatu alat yang mampu mencegah dan mengurangi tindak pencurian kendaraan bermotordengan menggunakan teknologi RFID, keypad password, Modul GSM dan isyarat suara. Pengaman Pengaktifan Kunci Kontak Motor Berbasis Arduino Mega 2560 menggunakan Arduino Mega 2560, RFID, keypad password, Modul GSM yang disatukan menjadi sistem yang berjalan dengan baik. RFID berfungsi membaca ID dari Tag RFID yang berfungsi untuk mengaktifkan keamanan pertama dan keypad berfungsi untuk memasukkan password serta mengaktifkan keamanan kedua dan relay kelistrikan motor.Ketika ada pencuri yang menekan tombol stater langsung tanpa melakukan tag dan memasukkan password, maka motor akan langsung mengeluarkan bunyi klakson dan mengirimkan SMS ke nomer ponsel pemilik.Maka pemilik tidak perlu khawatir akan terjadi tindak pencurian.

This paper describe about develop a hardware simulation with a hardware-in-the-loop principle for control system analysis dedicated to the practice of diploma students. The real system is simulated using a neural network based system model and the controller uses digital control. The system model is built based on real system input-output data. meanwhile, control of the system is built with digital PID control. Students can tune PID parameters and provide disturbance to the system model. The results of this study indicate that the system model is able to represent real systems and PID controllers are able to improve system performance when there is disturbance. Penelitian ini mengembangkan media pembelajaran untuk sistem kendali kontinyu menggunakan hardware-in-the-loop sehingga diharapkan dapat dihasilkan sistem proses di industri yang serupa dan identik yang dapat diujicoba secara langsung oleh mahasiswa. Hardware-in-the-loop yang dikembangkan merupakan sebuah rangkaian elektronika dan komputer dengan model sistem berbasis pada neural-network.
