SINTESIS DAN KARAKTERISTIK TiO2 DAN SiO2 SERTA APLIKASINYA TERHADAP KADAR Fe DALAM AIR SUMURABSTRAK Air merupakan kebutuhan yang terpenting dalam kehidupan manusia. Air berperan banyak dalam berbagai kegiatan manusia oleh karena itu kandungan yang ada di air harus bermanfaat bagi manusia. Banyak kandungan yang terdapat di air yang sangat bermanfaat, tetapi bayak juga kandungan air yang mungkin tidak bermanfaat bahkan bahaya jika digunakan oleh manusia, salah satunya yaitu kandungan logam berat terutama Fe (besi).  Sehingga tujuan pada penelitian ini untuk mengetahui penurunan kadar Fe (besi) dalam air sumur yang di lakukan dengan fotokimia dengan TiO2 dan SiO2 serta dapat mengidentifikasi karakteristik dari TiO2 dan SiO2. Sampel yang digunakan yaitu air sumur 300 m dibagi menjadi tiga masing-masing 100 ml dengan perlakuan yang berbeda. Pada sampel 100 ml pertama tidak diberikan perlakuan dan juga penambahan. Sampel 100 ml kedua diperlakukan dengan penambahan SiO2 dan pengadukan selama 1 jam, dan untuk sampel 100 ml ketiga diperlakukan dengan penambahan TiO2 dan pengadukan selama 1 jam. Ketiga sampel dengan perlakuan yang berbeda tersebut di analisis dengan menggunakan AAS (Atomic Absorption Spectroscopy) di Laboratorium Kimia Universitas Negeri Semarang. Hasil penelitian Analisis menggunakan AAS (Atomic Absorption Spectroscopy) menunjukkan hasil kadar Fe meningkat pada saat penambahan SiO2 dan TiO2 terhadap sampel yang tidak mendapatkan perlakuan tambahan. kadar Fe pada sampel yang tanpa penambahan sebanyak 0,206 mg/L, kemudian kadar Fe pada sampel yang ditambahkan SiO2 sebenyak 0,225 mg/L, dan kadar Fe pada sampel dengan penambahan TiO2 sebanyak 0,214 mg/L. Hal ini dikarenakan bentuk TiO2 dan SiO2 berupa suspensi. Kelemahan sistem suspensi ini adalah pemisahan partikel TiO2 memerlukan waktu yang lama dan biaya yang sangat mahal,serta daya tembus sinar sinar UV yang terbatas karena absorbsi yang kuat oleh TiO2 (efek bayangan) dan spesies organik terlarut. Kata Kunci: air sumur, TiO2, SiO2, Logam besi (Fe).   SYNTHESIS AND CHARACTERISATION OF TiO2 AND SiO2 APPLICATION TOWARD LEVELS OF Fe IN THE WELL WATER ABSTRACTWater is the most important need in human life. Also, water has many contributions in many human activities. Therefore, the existing content in the water must be beneficial for human. However, material contained in water may be beneficial yet dangerous for human as well, for instance heavy metals content, especially Fe (iron). The main objective of this study is to determine decreasing levels of Fe (iron) in the well water that is done by photochemical reaction using TiO2 and SiO2, and identify the characteristics of TiO2 and SiO2. Samples of well water used is 300 ml divided into three part, and every part of 100 ml water will be given different treatment. First 100 mL sample is not given any treatment and addition. Second 100 mL samples treated with the addition of SiO2 and stirring for an hour, and the third sample of 100 mL is treated with the addition of TiO2 and stirring for an hour. All of three samples with different treatments are analyzed using AAS (Atomic Absorption Spectroscopy) in the Chemistry Laboratory Semarang State University. The research result of analysis using AAS (Atomic Absorption Spectroscopy) shows Fe content increased as the addition of SiO2 and TiO2 in the samples than the sample without any additional treatment. Fe content in the sample without addition is 0.206 mg/L, while Fe content in the sample with addition of SiO2 is 0.225 mg/L, and Fe content in the sample with the addition of TiO2 is 0.214 mg/L. This caused by the form of TiO2 and SiO2 is a suspension. The weakness of this suspension system is the TiO2 particle separation takes a long time, very expensive, and also limited UV rays penetrating power because of the strong absorption by TiO2 (shadow effect) and may dissolved organic species. Keywords: well water, TiO2, SiO2, metals iron (Fe).
