<p align="justify">This research aims to know the effects of solvotermal temperature and duration on synthesis of Metal Organic Framework (MOF-5) thin film growing on Fluorine Tin Oxide (FTO) glass as substrate. Metal Organic Framework (MOF) is a porous polymer composed of metal ions having covalent bonds with organic ligands. MOF-5 consists of Zn4O binding to 1,4-benzenedicarboxylic (BDC) as the organic ligands. MOF-5 as an insulator material has large surface and high porosity that can be utilized as gas sensor, hydrogen storage and gas separation. MOF-5 thin film can be synthesized by solvotermal method, which is heating the mixture of organic ligands with metal ions in a solvent system. Time and temperature of synthesis, metals and ligands concentration and type of solvent are obtained. Substrate immersed in the solution is Fluorine Tin Oxide (FTO) glass. The solvent used is N, N-dimethyl-formamide (DMF). After heating, the crystal of MOF-5 will be grown on the substrate, continued by drying process. The formed MOF-5 thin film were characterized by Scanning Electron Microscope (SEM) to determine the crystal morphology, method of Bruneauer, Emmet and Teller (BET) to characterize the surface area, and Powder X-Ray Diffraction (PXRD) to determine the crystalline phase. <br /> <br /> <br /> In this study, MOF-5 was solvothermal synthesized on Fluorine Tin Oxide glass with a more uniformly distributed material at a temperature of 150°C and a duration of 8 hours. <br /> <p align="justify">
