SYNTHESIS OF RUTILE TIO2 NANOPARTICLES BY CO-PRECIPITATION METHOD Nazaruddin Nasution; Aida Fitri
FISITEK: Jurnal Ilmu Fisika dan Teknologi Vol 2, No 2 (2018)
Publisher : Universitas Islam Negeri Sumatera Utara Medan

Abstract. The objective of this research is to produce rutile TiO2 nanoparticles by co-precipitation method and to determine its characterization using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), X-ray Diffractometry (XRD), and Particle Size Analysis (PSA) methods. Synthesis of rutile TiO2 nanoparticles by co-precipitation method in this study was initiated by mixing 15% TiCl3 solution into distilled water while stirring at constant speed for some time. Then, pH is adjusted to 11-13 by dripping ammonia (NH4OH) solution while continuing to stir. The precipitate (white gel) is then dried in the oven and crushed to produce TiO2 powder. The morphology of the TiO2 particles obtained is spherical and tends to agglomerate. The average particle size of TiO2 produced is 192.2 nm. The EDS results show that the percentage of Ti mass in TiO2 particles is 59.52%. Based on XRD analysis, there are two phases formed namely anatase and rutile with a tetragonal crystal system.Keywords: Co-precipitation method, nanoparticles, and rutile.

The kitchen is one of the places most concerned by every community because the biggest fire potential in the house lies in the kitchen, the source of fire that often causes fires in the kitchen is a stove and gas. Therefore we need a design of a kitchen security system based on the ATmega32 microcontroller using flame sensors, MQ-2 and MQ-6. This study aims to produce a performance tool that will detect any movement of fire, gas, and smoke using an Early Warning System. The warning in the form of an alarm sounds, the fan turns, and the door opens automatically. Sensor detection is designed with 4 conditions namely Normal, Caution, Alert and Danger. The results of testing using the Flame sensor found a wave range from 22 nm to 1022 nm from normal to hazardous conditions, the MQ-2 found the results of testing from the ADC (Analog Digital Converter) with concentrations from 0 ppm to 130 ppm from normal to hazardous conditions, and the MQ-6 test results were obtained from the ADC (Analog Digital Converter) with concentrations from 0 ppm to 520 ppm from normal to dangerous conditions. Keywords : Kitchen, ATmega32, Flame sensor, MQ-2, and MQ-6.

Pemanasan global saat ini telah menyebabkan cuaca menjadi kurang menentu, sehingga musim kemarau dan hujan tidak lagi dapat diprediksi. Kondisi cuaca yang tidak menentu dapat mempersulit proses pengeringan pakaian. Oleh karena itu, perlu dirancang sistem otomatisasi penjemuran pakaian berbasis mikrokontroler arduino uno yang menggunakan sensor hujan dan sensor LDR. Penelitian ini bertujuan untuk mengembangkan alat kinerja yang akan menggunakan sistem otomatis untuk mendeteksi apakah ada ada hujan, tidak ada cahaya atau cuaca dalam keadaan mendung. Sistem otomatis berupa jemuran yang menggunakan motor stepper yang akan menarik tali jemuran masuk atau keluar dan pemberitahuan dari DFPlayer Mini. Desain pendeteksian cahaya hujan memiliki 4 status: hujan – siang, cerah – malam, cerah – siang, dan hujan – malam. Dalam setiap kasus, motor stepper menarik tali jemuran masuk atau keluar. Hasil dari penelitian ini menunjukkan bahwa sistem otomatisasi dapat mendeteksi besar curah hujan yaitu 0,1 mm – 817 mm, dan besar intensitas cahaya yaitu 5 Lux – 506 Lux.
