Abstract

Penelitian ini merupakan penelitian dengan pendekatan kuantitatif yang bertujuan untuk mengetahui pengaruh deklinasi magnetik pada kompas dan koordinat geografis bumi terhadap akurasi arah kiblat. Pengambilan data menggunakan teknik Cluster Sampling dengan populasinya adalah wilayah Indonesia yang dibagi menjadi dua kelompok yaitu wilayah yang letak geografisnya dekat dengan khatulistiwa dan wilayah yang letak geografisnya jauh dari khatulistiwa. Data diperoleh melalui dokumen, observasi dan perhitungan matematis dengan menggunakan rumus spherical trigonometri. Selanjutnya, data hasil penelitian dianalisis menggunakan analisis varian (ANAVA) dua jalur. Hasil penelitian menunjukkan bahwa deklinasi magnetik pada kompas, baik yang bernilai kurang dari satu derajat maupun lebih dari satu derajat memberikan kontribusi yang signifikan terhadap akurasi arah kiblat. Koordinat geografis bumi baik yang letaknya dekat maupun jauh dari khatulistiwa memberikan kontribusi yang signifikan terhadap akurasi arah kiblat. Di samping itu juga tidak terdapat hubungan interaktif antara deklinasi magnetik dengan koordinat geografis bumi yang dari interaksi itu akan berpengaruh terhadap akurasi arah kiblat.

Abstract

This study aims to determine the implementation and accuracy of the Jean Meeus Algorithm in determining lunar and solar eclipses.This research is a qualitative research with a literature approach. The primary data source for this research is a book entitled Astronomical Algorithm by Jean Meeus. Meanwhile, secondary data is all information related to the Jean Meeus algorithm in determining eclipses obtained from various literature such as books, websites, encyclopedias, dictionaries, scientific articles, and other sources of information. The results of this study indicate that determining the eclipse time using the Jean Meeus algorithm involves seven stages of calculation namely; starting with determining the year the eclipse occurred, then determining the gamma value, JDE (Julian Day Ephemeris), the payoff value (k), the saros series, the reference time (To) and the Bessel Element value. The calculation of the Jean Meeus Algorithm is included in the tahkiki essential reckoning method because the calculation process involves astronomical data with very precise corrections for the motion of the Moon and the Sun, This method is also based on the heliocentric flow. In addition, the level of accuracy of Jean Meeus' calculations has a good match with NASA as a comparison, namely with results that are only 1 to 3 minutes apart and the average difference is only in seconds.

Abstract

Atmospheric humidity can affect the Rukyatul Hilal process. The greater the humidity the more difficult it is to observe the hilal, because the greater the humidity the more moisture and the more cloud growth. Therefore, the purpose of this study is to determine the level of atmospheric humidity that can affect hilal visibility at the location of Rukyatul Hilal Loang Baloq Beach. This type of research includes field research (field reseach) using a qualitative approach. The source of data from this study is the result of direct observation to the research location and collecting data from several institutions, namely, the Ministry of Religious Affairs of West Nusa Tenggara (NTB) and the Lombok Meteorology, Climatology and Geophysics Agency (BMKG). The findings of this study that atmospheric humidity affects Rukyatul Hilal on Loang Baloq Beach, because Loang Baloq Beach has a high level of atmospheric humidity. So it is difficult to observe the hilal image. If the state of atmospheric humidity is 70%, then the state of the sky will be clear. If the state of atmospheric humidity is 70% – 80% then the state of the sky will be cloudy, and if the state of atmospheric humidity is 85% then the state of the sky will rain. Atmospheric humidity at Loang Baloq Beach has an average of 84.5% throughout 2022, with this figure atmospheric humidity will be able to affect visibility on the hilal at Loang Baloq Beach.
