The construction of Dhaha Kediri Airport in Kediri City has caused an increase in investors' desire to invest their businesses in Kediri City. This is reinforced by the very high GRDP level of Kediri City over the last three years. The high interest of investors to invest in the City of Kediri is not accompanied by the efforts of the Government of the City of Kediri to provide an analysis of each sector in the City of Kediri so that investors find it difficult to identify and predict the sustainability of the sector they wish to invest in. The research carried out resulted in an information system that can provide information on the development of GRDP for each sector of the city of Kediri from 2017 to 2021. In addition to the information system built, it can provide the value of the contribution of each sector and classify the seventeen existing sectors into leading sectors and non-seeded ones using Location QUotient analysis. The information system was developed using PHP programming and MySQL RDBMS. The final results of calculations using Location QUotient analysis found that the City of Kediri only has one superior sector, namely the Manufacturing or Manufacturing industry sector. Meanwhile, other sectors are still not well developed so they require support from outside investors to develop these sectors.
