<![CDATA[Arduino is a Microcontroller platform consisting of a computer chip that is used to control electronic equipment that is flexible and easy to use. In this modern era, the implementation of Rukyatul Hilal can be done using instruments such as Hilal locater, telescope and theodolite. However, these tools are quite expensive and have a fairly heavy load and require long time to prepare. Therefore, this research provides breakthroughs and new innovations in designing the Rukyatul Hilal Instrument based on Arduino. The research uses the Research and Development model type of research, the development model that the researcher will do is to develop an Arduino Microcontroller so that it can be used as a Rukyatul Hilal Instrument. Based on 4 observations of the Moon, The Arduino-based Rukyatul Hilal instrument can successfully show the position of the Moon and verify the data used by the author is correct and the author can also photograph the image of the Moon clearly using a smartphone. However, it should be noted that the position of the Moon when viewed from the Arduino-based Rukyatul Hilal Instrument telescope is not in the middle of the telescope, but sometimes at the bottom, side and top.]]>

<![CDATA[Zodiacal light is a night sky phenomenon that can occur before or after dusk. Additionally, zodiacal light is referred to as false dawn (fajar kadzib) or false dusk. Zodiacal light is emitted by the dust leftovers of asteroids, comets, and other extraterrestrial objects colliding along the planet Mercury's orbit to Mars. This remaining material orbits the Sun in the same direction as the four planets. When the Sun illuminates the leftover dust, it appears as a zodiacal light in the hemisphere that experiences dawn or dusk. By using linear fittings we detect the presence of zodiacal light on the light curve of the night skybrightness. The Observations were made using a digital camera and SQM. From a number of observational data obtained at six locations, it shows that there is an identical linear pattern. From this linear model, it can be seen that the zodiacal light has been observed since the sun's position at -60 degrees below the horizon. Recognizing the presence of the zodiacal light is very important to know the time of the appearance of true dawn which is the beginning of the time for the dawn prayer.]]>

<![CDATA[This article aims to reconstruct the old science adopted by ancient Muslim astronomers at that time due to the absence of technology to guide on sea and land. This paper adopts a qualitative method to describe the precise technique and strategy of its application for direction identification through the selection of several Stars, Satellites, Constellations and Coordinate which are visible both from the northern and southern parts of the northern Nigeria sky. On the other hand, several challenges were identified to affect the development of science in different dimensions such as total dependence on artificial innovative devices which may very well have limitations. This article recommends awakening to Astronomers, especially Nigerian Astronomers, to pay more attention to scientific aspects as the basis for the use of modern astronomical technology in every observation of celestial bodies.]]>

<![CDATA[Ḥanafī's opinion differs from that of Al-Shāfi’ī in determining the entry of the time for the 'Asr prayer and the time for the Isha prayer. These two different determinations can be easily identified using the contextual method (calculation). The data needed in calculation is the high value of the Sun, so the thought of Ahmad Ghazali, an astronomer from Madura, explained about the height of the Sun based on two schools of thought. This provides a treasure of knowledge to someone in determining the entry of prayer times based on madhhab, just by looking at the clock. The type of method used in this study is qualitative field research with a descriptive approach, the aim is to describe Ahmad Ghazali's thoughts and to analyze in the field the given method. The results of the Anfa’ al-Wasīlah calculation with the addition of 1 in the irtifā’ formula is in accordance with the opinion of Al-Shāfi’ī, and an additional 2 in the irtifā’ formula according to the opinion of Ḥanafī, while from Ahmad Ghazali's opinion it states that the two early determinations of the time for the Asr prayer This is true, but it is more appropriate to use the ‘Aṣr Awwal time, because the ‘Aṣr Awwal opinion is supported by a number of scholars and strong arguments.]]>

<![CDATA[Calendars with cultural nuances are part of local wisdom that should be preserved, one of which is the formulation of Sheikh Abbas Kutakarang's calendar from Aceh. This article aims to see how Sheikh Abbas Kutakarang shaped local wisdom in the method of determining the classical Hijri calendar in Aceh. This article is qualitative in nature by using library data with content analysis method. The primary data source used is the book of Tāj al-Mulūk by Sheikh Abbas Kutakarang. This article finds that there are characteristics of local wisdom in determining the classical Hijri calendar in Aceh in different methods and algorithms from classical Javanese reckoning. These differences have an impact on differences in determining the beginning of the Hijri year. This method is a representation of local wisdom in the Hijri calendar in Aceh.]]>

<![CDATA[The sun's shadow and the Qibla azimuth are two techniques for figuring out the Qibla direction. To obtain Qibla direction accuracy while applied to traditional instruments with low accuracy, such istiwa'ayn, the user's accuracy is required. Slamet Hambali's theory of a process angle was inspired by this issue. The effective angle disparity formula, which is based on Slamet Hambali's concept, is discussed in this article along with how it can be used to get effective azimuth variance. This article is based on numerically-based quantitative research using library data. The aim is to comprehend the concept of various effective azimuths and how they are used to identify the direction of the Qibla. This article comes to the conclusion that Slamet Hambali's formula for the effective azimuth difference tends to make use of the idea of processing angle by calculating the azimuth difference value with particular aiming hours, azimuth difference value, and processing angle to produce a shooting clock with a different azimuth valuation.Kata kunci : azimut, efektif, jam bidik ]]>

<![CDATA[The community experiences both positive and negative consequences as a response of Qibla direction calibration, particularly in the ancient mosque, an ancestral heritage mosque whose authenticity must be preserved. One of them is the Air Tiris Great Mosque in Kampar, which must be preserved from the initial stages of growth because it is a tourist destination and an item of cultural heritage. This article aims to verify the calibration of the Qibla direction of the oldest mosque in Kampar and the techniques employed by earlier scholars in measuring their Qibla direction using field investigations and data sources from observations and interviews. This article concludes that the Qibla direction is accurate and correct, the Air Tiris Grand Mosque was established in 1901, and that it has never undergone renovation. When the global Qibla direction was wrapped in religious intuition, the cleric at the time, Datuk Engku Mudo Songkal, used the sun's shadow to bring religious intuition and scientific truth together.]]>

<![CDATA[The tool for calculating prayer times continues to develop. Likewise, there are several different formulas for calculating prayer times, both with the addition of altitude correction and without altitude correction. This article uses the prayer time formula which takes into account altitude corrections into an application called Islamic Astro Time which uses Matlab programming with solar data from the astronomical algorithms formula by Jean Meeus. This article is an experimental qualitative with descriptive analysis. This article finds that the calculation of prayer times in the Islamic Astro Time application using varying altitude levels results in different times. The difference in results starts from 2 minutes at a building height of 250 meters to more than 2 minutes depending on the level of height. The higher the position of the person praying, the greater the difference between the start of the prayer and the lower place. So that every Muslim who wants to pray must pay attention to the altitude correction factor with the sun's position approaching the horizon, namely the time of dawn, late dawn (ṭulū'), maghrib, and evening prayers.]]>
