Abstract

The people of Lombok and Bali initially used palelintangan, but in its development, the Balinese leaned more towards astrology. Most of the Sasak tribe, the people of Lombok, work as farmers and have been friends with nature since their ancestors existed. The evidence is that they utilize nature as a sign before carrying out their activities by calculating a lucky day or the right time, the beginning of the year, and changing seasons based on constellations, besides that natural signs are also considered. However, there has yet to be a complete study. What is palelintangan? How is the concept and implementation of palelintangan? Moreover, how does palelintangan affect the Sasak tribe? This study employs the library method. The main data source comes from a book entitled 'Traditional Astronomical Studies (Palelintangan) in Lombok, West Nusa Tenggara' and the additional data sources are taken from journals and scientific papers related to palelintangan. The data analysis's results discover that pelentangan is a traditional astronomy that has been implemented and was outlined in the form of wariga boards and rowot calendars to calculate the lucky days and determine the time related to the Sasak people's lives.

Abstract

The purpose of this research is to find out how to determine the Qibla direction of aplace using the position of the planet Venus and how to prove the calculation of the position ofVenus in the sky. This research is motivated by the question of how to determine the Qibladirection at night if the conditions do not have sophisticated technological equipment. Thisresearch is a descriptive analysis research where all the data is collected through observationtechniques. The research results show that the position of the planet Venus can be used as analternative reference to determine the Qibla direction. Based on observations using astronomicalcalculations, it is known that Venus looks very luminous on the western horizon when the sky isclear and the sun has set perfectly. We can also see one of the planets Venus at dawn on theeastern horizon, so Venus is also often referred to as the morning star. Data on the position of theplanet Venus such as the altitude and azimuth of the planet Venus somewhere are then calculatedusing the horizon coordinate system. The data is used as a theodolite reference. Furthermore, toobtain the actual Qibla direction, the theodolite lens is directed to the position of the planet Venusand rotated clockwise (same as the difference in the azimuth angle with the Qibla azimuth ofVenus). Thus, the position of the planet Venus can be used as an alternative to determine the Qibladirection.

Abstract

Based on the Sipariama cycle described in the Lontara Pananrang, we aim to determine a reasonable timing schedule for farming activities in this study. The Buginese people utilise this as a rule of thumb because they believe that the same occurrences occur every eight years and by observing natural signals, they may be certain in their forecasts for this auspicious period. In addition, since the Sipariama cycle's calendar system is based on the Hijri month, which employs the lunar calendar system, this research also attempts to establish a link between the moon's motion and the occurrence of climate change. By comparing the findings of the analysis in the sipariama cycle with the findings of the analysis of the data that had been obtained, the data listed in this paper were taken from the results of analysis from journals related to Lontara Pananrang. According to the findings of this study's work, the Sipariama cycle, which lasted for eight years, solely had a numerical basis. then climatic change, namely the occurrence of air tides, is influenced by the motion of the moon.

Abstract

Historians present the origin of the Javanese Islamic calendar by associating it with Sultan Agung, in contrast to the explanation in the fiber Widya Pradhana, Ronggowasito precisely mentions that the Javanese Islamic calendar was formulated by Sunan Giri II. So it can be examined is there a difference between the calculation of the calendar formulated by Sultan Agung and Sunan Giri II as described by Ronggowasito. This study used a qualitative descriptive approach, with secondary data taken from the manuscript fiber Widya Pradhana. The results of the study will be divided into two, the difference in terms of calculation and in terms of the function of the Javanese Islamic calendar in both versions.

Abstract

The Javanese Islamic Aboge calendar is one of the local Indonesian calendars whose calculations are static and standard. The Javanese calendar is a special calendar because it is a blend of Islamic culture and Javanese Hindu-Buddhist culture whose calculations are based on the moon around the sun. Astronomically, the Javanese calendar is classified as a mathematical calendar, while the Hijri calendar is an astronomical calendar. Methodologically this paper is a Research Library where the data collected comes from library sources that are considered representatively related to the object of this study. This paper is descriptive-analytical, where this paper will explain and explain the truth and error of a fact. Then also analytically developed in a balanced manner by looking at the advantages and disadvantages of the object under study. According to the reckoning rukyah discourse, the Aboge system which includes 'urfi reckoning is no longer relevant to what is required by syara' and cannot be used in determining the beginning of the Lunar month related to the implementation of worship (determination of Ramadan fasting and holidays). Because according to this system, the age of Sha'ban remains 29 days while the month of Ramadan also remains 30 days.

Abstract

This research discusses the history of the calculation of the date of Easter as part of the reform of the Gregorian calendar using a historical approach. It examines the history of the determination of the date of Easter by the Council of Nicaea in 325 AD and the use of the ecclesiastical full moon method to calculate the date of Easter. This research also discusses the differences in the dating of Easter in the Julian and Gregorian calendars and the relationship between the dating of Easter and the astronomical vernal equinox. The results of this research show that the date of Easter is calculated based on mathematical calculations, taking into account the ecclesiastical full moon and is no longer related to accurate astronomical calculations. This research provides a clear overview of the history and methods of determining the date of Easter and can serve as a reference for scientists and researchers to further study the reform of the Gregorian calendar and the calculation of the date of Easter.

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

This study aims to determine the new moon's position towards Mount Agung in mapping at the beginning of the Lunar Month at the Loang Baloq  Beach Rukyat location. Loang Baloq Beach has been a routine location for the new moon sightings carried out by the Mataram BMKG team since 2013. However, The hilal is rarely reported to be visible at Loang Baloq Beach. The presence of Mount Agung hinders the condition of the new moon. Based on the study's results, it can be determined that the condition of Loang Baloq Beach does not meet the ideal assessment criteria. This is because the west is not clear at Azimuth 294o46'36.40". Then the west horizon of the Loang Baloq beach is blocked by the presence of Mount Agung in the Karangasem district of the island of Bali. In addition, the existence of Mount Agung causes the western horizon of the Loang Baloq coast always to be unclean or always cloudy, even though the local weather conditions are hot/sunny, Although Loang Baloq Beach does not meet the ideal criteria as a place for the sighting of the new moon. However, this location has enough potential for the sighting of the new moon compared to other locations in Mataram. Even if the new moon's position from Loang Baloq is right on Mount Agung, the new moon cannot be seen, but if it is to the left and right of Mount Agung, it is still possible to see the new moon. It is also possible to see the exact position of the new moon on Mount Agung if the height of the new moon is above Mount Agung. The mapping of the new moon position is carried out in the months of Muharram, Safar, Rabiul Awal, Rabiul Akhir, Jumadil Awal, Jumadil Akhir, Rajab, Shaban, Ramadhan, Shawwal, with the results of the appearance of the new moon being to the left of Mount Agung. In contrast, the month of Dzulqoidah, Dzulhijjah with the appearance of the new moon is right with Mount Agung. When the hilal position is right at Mount Agung, the observer shifts to another location, Tanjung Mina, North Lombok Regency.

Abstract

The development of science encourages the presence of new methods in determining the beginning of the prayer time. One of them is the reckoning method which utilizes astronomical data to determine the beginning of the prayer time. This study aims to simulate the initial calculation of prayer times based on ephemeris data from the National Oceanic and Atmospheric Administration (NOAA) using a spreadsheet. The prayer times resulting from the simulation are not much different from the prayer times published on the BIMAS Kementerian Agama Republik Indonesia website
