Abstract: Based on the
researcher's observations, the influence of Islamic da'wah and education
carried out by Yayasan Rahmatan Lil 'Alamin needs to be studied in depth to
identify the aspects of effectiveness and challenges faced by this institution
in carrying out its mission. Through this study, emphasis will be given to the
extent of the effectiveness of Islamic education in guiding converts towards an
appreciation of the true teachings of Islam. An analysis will also be carried
out on the da'wah programs and activities implemented by this foundation, as
well as their suitability with the current needs of converts. Through a study
of the experiences of other institutions that are also active in the field of
Islamic da'wah and education, it was found that there is still a great need to
develop a strategy that is more effective and relevant to the unique needs of
converts in non-Muslim societies. Islamic education in this context needs to be
holistic, with the goal of guiding converts to develop spiritually and be able
to adapt socially in a balanced way. This study was conducted to develop and
validate an instrument based on the Exploratory Factor Analysis (EFA) process
to measure the factors Religious Field, Field of Worship, Morality. This study
used a quantitative research method by analyzing the relationships between
variables in the study model. Before the data was analyzed, Exploratory Factor
Analysis (EFA) was conducted to identify the suitability of the items used in
the study instrument. This study explains in detail the procedure for
conducting Exploratory Factor Analysis (EFA) for each factor. The findings of
this study show that the validity values based on Kaiser-Meyer-Olkin (KMO),
Total Variance Explained (TVE), Factor Loading and reliability values based on
Cronbach's Alpha, have met all the required values.
