Abstract

ZnO is an inorganic material that has many benefits, one of which is in the pharmaceutical field. So far, the synthesis of inorganic materials has been carried out using high temperatures. Research was carried out to synthesize ZnO using hydrothermal at 180°C for 24 hours then burned at temperatures of 300, 600, and 900°C for 6 hours. The compound resulting from synthesis at 180°C was obtained by the compound [Zn(urea)3](NO3)2 which decomposed into ZnO nanoparticle compounds at 300°C to 900°C. ZnO synthesized at temperatures of 300, 600, and 900°C has a hexagonal structure, space group P63/m with lattice parameters a=b= 3.25 Å and c= 5.21 Å and ? = ? = 90° and ? = 120°. The synthesized ZnO has a nanoparticle size in the range of 172-455 nm. Keywords:          ZnO, hydrothermal, synthesis, nanoparticle, hexagonal structure   Abstrak ZnO merupakan material anorganik yang memiliki banyak manfaat, salah satunya dalam bidang farmasi. Selama ini sintesis material anorganik dilakukan menggunakan suhu yang tinggi. Penelitian dilakukan untuk mensintesis material ZnO pada suhu rendah. Metode sintesis material ZnO dilakukan dengan menggunakan hidrotermal pada suhu 180°C selama 24 jam kemudian dibakar pada suhu 300, 600, dan 900°C selama 6 jam. Senyawa hasil sintesis pada 180°C diperoleh senyawa [Zn(urea)3](NO3)2 yang terurai menjadi senyawa nanopartikel ZnO pada 300°C hingga 900°C. ZnO hasil sintesis pada suhu 300, 600, dan 900°C memiliki struktur heksagonal, grup ruang P63/m dengan parameter kisi a=b= 3,25 Å dan c= 5,21 Å serta memiliki sudut ? = ? = 90° dan ? = 120°. ZnO hasil sintesis memiliki ukuran nanopartikel dengan rentang 172-455 nm. Kata Kunci:         ZnO, hidrotermal, sintesis, nanopartikel, struktur heksagonal

Abstract

In various studies, rosella flowers can cure various diseases, prevent disease transmission and are used as processed food or health drinks. The increasing use of rosella flowers can be a business opportunity and can improve the community's economy, but limited knowledge, skills, abilities, creativity, innovation and inadequate guidance are obstacles to the community in utilizing rosella, so training is needed to increase people's knowledge and skills in utilizing rosella. and home product development. The purpose of carrying out this activity is to increase public knowledge about rosella plants, how to make rosella flower tea and how to increase the economic value of a product. This activity was carried out using the training method, beginning with the provision of material on rosella and how to increase the economic value of a home product, followed by direct demonstrations and practice of making rosella flower tea. This activity is useful for increasing public knowledge regarding rosella plants, the use of rosella flowers, how to make rosella flower tea and how to increase the economic value of a home product.
