Facing Qibla ( Kaaba in Mecca ) and getting the correct direction of it are the obligations which every Muslim need to do when they are performing salah. So it is truly important for them to learn how to determine the qibla properly correctly so that they will be able to find out the it easily wherever they are. Finding out the Qibla is not hard to do because there are many classic and modern astronomical instruments which have the function as Qibla Finder but it is for sure we will not be able to use them if we do not learn how to operate those instruments properly. People are also confused to choose which tool is the most accurate and simple one to use because there are too many qibla finders which are created. So on this opportunity the researcher have made the limitation for the qibla finder which would have discussed, those are Mizwala and Istiwa’aini. They have many similarities but totally different that is why the researcher are interested in doing research about them.
The research is quantitative which uses field research. The data is obtained from some sources and direct measurement at field. Considering that it is a field research so it has two types of data, those are primary source and secondary source. The primary source is the result of the astronomical calculations and measurements to determine the qibla direction using Mizwala and Istiwa’aini. Then the Secondary data is obtained from books, articles, and journals which explain about qibla direction. The methods of data collection are interview, observation and documentation. Then for for the methods of data analysis, the researcher uses a qualitative research method using descriptive approach and comparative.
The location for the research was in Masjid Al- Ikhlas, BPI, Ngaliyan, Central Java by the data, Latitude (ϕ^x) = 6°59'35”, Longitude of place (λ^x)= 110°21'12", Longitude (λ^d)=105° (Wib), Measurement Time (WD)=14.00, Declination At the time of measurement (δ)= 23°56'17”, Equation of time

(e)=0m 3d. The research was conducted in the beginning of 2020 for two times ( 2 days) at 14.00 WIB everyday . The instruments used were Mizwala and Istiwa’aini.
The result of the research has shown that there is no much difference between both tools. In addition the researcher has ever read and learnt the thesis which have written by Muhammad Adieb ( Studi Komparasi Penentuan Arah Kiblat Istiwqaaini Karya Slamet Hambali dengan theodolite, (UIN Walisongo Semarang: 2014 ) which explained about the comparacy between theodolite and istiwa’aini in determining the qibla direction by the result is only less than 2 degree the difference of measurement between Theodolite and Istiwa’ain . So, based on that research, it means Istiwa’aini is not only accurate to find out the qibla but also it has function as parameter for the measurement result of the research of this thesis which have been written by the researcher about the Comparative Study of Mizwala and Istiwa’aini as Qibla Finder. The result of the thesis is less than 1,2 degree for the difference between both tools. It means Mizwala and Istiwa’aini are accurate qibla finder even though they have several strengths and weaknesses.
