<![CDATA[Quadratum Geometricum is a surveying and astronomical instrument by George Von Peurbach who is known as an Austrian astronomer. This article discusses the accuracy and development concept of Quadratum Geometricum which is named Neo Quadratum Geometricum. This research is development research, which has 2 stages, namely the preliminary stage and the formative evaluation stage which consists of: self evaluation, prototyping (expert reviews and one-to-one, and small groups), and field tests. The findings of this study include: Neo Quadratum Geometricum innovation, namely the existence of a conversion arc from the value of the horizontal and vertical rulers which serves to value of the angle of tan/cotan immediately known without looking at the table. Quadratum Geometricum is more accurate in the tan angle conversion test, Neo Quadratum Geometricum is 0.0025 greater than the calculator, while Quadratum Geometricum is the same. Because, the accuracy of Neo Quadratum Geometricum is only up to minutes. However, in terms of the effectiveness of using Neo Quadratum Geometricum it is more practical, because it does not use tables. In measuring the height of the object, the difference is 8.5 cm from the actual height.]]>

<![CDATA[Indonesia, has two calendars that have been strongly attached to the way of life in its society. These are the Gregorian calendar and the Hijri calendar. In addition, each region of Indonesia also has its own traditional calendar system. One type of traditional calendar that is still alive today is the Rowot Sasak Calendar. The Rowot Sasak Calendar uses the Moon as the base for its calculation system, so it is very similar to the Hijriyah system. But as a traditional calendar, the cultural components in it are very similar to the Islamic Javanese Calendar. So the author is interested in further research on the existence of cultural acculturation between Islam, Java and Sasak in the Rowot Sasak Calendar. This research uses qualitative methodology with field study research type and descriptive qualitative analysis. The findings of this study indicate that there is a strong acculturation between the three cultures in the rowot sasak calendar. The acculturation is based on the system that uses the Islamic calendar (Hijriyah) urfi hisab system. This is proven by the names of the months that adopt from the Hijriyah calendar, as well as the number of days 29/30 each month. Meanwhile, the Javanese cultural element can be identified in the component of determining good days for the community. In addition, the use of market names such as kliwon, wage, pahing, pon and legi is strong evidence of Javanese cultural acculturation. While the elements of Sasak culture itself can be found in the mention of the name of the day and other cultural terms that use terms in the Sasak language. As well as the determination of mangse (season) which uses the 5-15-25 tradition benchmark with synchronization on the Hijriyah calendar.]]>

<![CDATA[Al-kashi was a Persian astronomer who was nicknamed the second Ptolemy. The important work is zij named zij khaqani. This Zij has a deficiency in terms of the epoch or reference calculation in 851 Persia or November 16, 1481 M. This Zij has the potential to be developed so that it can be used as the initial reckoning of the lunar month. This research was conducted by Qualitative methods. Techniques for collecting data using literature. The problem the author wants to know is 1). What is the zij al-Kashi compilation algorithm? 2) How to reformulate zij al-Kashi as the initial reckoning of the Kamariyah Month? 3) how is the accuracy of Zij al-Kashi post reformulation as the initial reckoning of the month of Kamariyah? This research produces first, zij al-kashi uses Ptolemy's theory to correct the movement of celestial bodies. Al-kashi still considers the movement of celestial bodies in the form of circles instead of ellipses. Second, Reformulation is carried out by renewing the epoch, the dating system, correction for six months of movement disorders. Third, Contemporary reckoning in this case is used by Jean Meeus. Accuracy tests were carried out in critical years for the initial determination of ramdahan, Syawal Dzulhijjah. These years are 1427, 1428, 1432, and 1439. 14 The difference in the height of the modified zij al-Kashi hilal with contemporary reckoning is at intervals of 3-11 minutes of arc. The smallest difference is 3 minutes of arc and at most 11 minutes of arc.]]>

<![CDATA[This study was motivated by the researcher's attention to the beginning of the Asr prayer time, which in its determination requires high accuracy and a long formula. Because in determining the beginning of the 'Asr prayer time, the height of the Sun must be found first using the Sun's height formula. So a tool is needed that is easier to determine the beginning of the Asr prayer time without very long calculations, namely Al-Murobba'. Thus the focus of this study is to find out the accuracy of Al-Murobba' in determine the beginning of Asr prayer time. This research is categorized as field research with a descriptive qualitative approach. The sources and types of data used are Al-Murobba' instruments and several books, articles and scientific journals that are in accordance with the research theme. While the analysis uses data reduction, data presentation and conclusion writing. The results of this study indicate that Al-Murobba' has accuracy is categorized as quite accurate. This is evidenced by the results of the researcher's observations 5 (five) times by comparing the results using the spherical trigonometry calculation method. The time gap which is shown in Al-Murobba' and spherical trigonometry is 0-2 minutes.]]>

<![CDATA[The advancement of this technology is the increasing number of alternative ways to determine the direction of the Qibla, one of which is by using an andoid cellphone in which there is a google maps application feature. but how to determine the direction of Qibla using google maps application is not many people know even though it can be said that almost all muslim communities have Android phones and have google maps applications. so in this article raised two formulations of the problem. First, how the analysis of Qibla direction determination using Google Maps application astronomical perspective. Second, how the analysis of Qibla direction determination using Google maps application Fiqh perspective. This research is of qualitative type with a focus on astronomy and fiqh studies. Primary Data is the result of observations and interviews related to determining the direction of Qibla using google maps application. with data analysis techniques used are descriptive-analytical. The study produced two findings. First, determining the direction of Qibla by using the google maps application is very easy with several stages, namely first looking for the Kaaba on the search menu and finding the location of our place where we are. for the determination of the direction of prayer with the Google maps application has weaknesses including the Qibla direction that can be determined with the google application can be used for buildings that are already standing. determining the direction of Qibla with Google Maps can only be applied to buildings, can not be applied to vacant land. Determination of the direction of Qibla with Google Maps on a large building that is clearly visible image, it will be easy to put the paper on the phone with the right, with reference to one / more sides of the building in the picture. Determining the direction of Qibla with Google Maps on a small building and the picture is not clear, it is difficult to put paper on the phone precisely, because it is not clear to see the reference to one/more sides of the building in the picture. Determining the Qibla direction with Google Maps on empty land cannot be applied. so that ijtihadong has been done using the google maps application, the intended direction of the results of this ijtihad makes a person more confident that he has been facing the Qibla. in fiqh dzan strong is something that can not be replaced by any doubt, in accordance with the rules اليقين َل يزال بالشك so long as a person has been convinced from the results of his Ijtihad that he is really facing the Qibla, then he has really been facing the Qibla and his prayer is valid.]]>

<![CDATA[Observing the crescent moon to determine the beginning of the Hijri month has important notes in the form of the validity of the observation results and contrast problems. The application of astronomical observation technology and instrumentation can help the crescent moon observation process to increase the validity of observation results and increase contrast, including the use of an Open Computer Vision (OpenCV) based observation system. In OpenCV you can run a multiview menu, which displays several image profiles at once even if you only use 1 (one) camera instrument. Various models and observation systems have been widely applied, but it is necessary to quantify them to see the effectiveness of the observation results. Analysis of the effectiveness of observation results can be done by measuring the resulting image contrast value. From 8 data from observations carried out on 19 July 2023 in Sidarjo (7°27'39.2" S 112°39'23.2" E), with Michelson contrast, a very significant increase in the image contrast value was obtained, namely an average of 0, 90, with the lowest increase of 0.86 and the highest contrast increase of 0.92.]]>

<![CDATA[The Wehea Dayak is one of the Dayak tribes that still exist today. The Wehea Dayak tribe lives in close proximity to nature. They depend on the surrounding rivers, mountains, and forests. Daily activities cannot be separated from farming and hunting. This activity has a close relationship with the Dayak Wehea traditional activities. In determining the time of traditional activities, the Wehea Dayak people still use the Wehea Dayak calendar, which is a legacy from their previous ancestors. The Dayak Wehea calendar is unique among most calendars in Indonesia. The Wehea Dayak calendar only has two elements, namely the 29/30 months and the 10 periods. The Wehea Dayak calendar does not recognize years like other calendars. This research examines how the Dayak Wehea calendar is implemented in the traditional activities and rituals of the Dayak Wehea community in Muara Wahau District. This research is field research conducted in Muara Wahau District in August and December 2017. This research uses a qualitative approach to describe the research results. The results of this research explain that the Wehea Dayak people use this calendar for ten periods, which refers to traditional activities. This implementation includes determining the cutting period (Nep bloh), farming time (Nemeq), time to plant rice (Nugal), rituals in the fields (Entaglel), the ritual of welcoming the rice that begins to contain (Embeq Hemin Plai), harvest time (Neljiang), the period of completion of harvest (Mel Haq Pangseh May), rice feast (Erau/Lom Plai), time to make a hut (Naq Jengea), and finally the children's era/wedding party (Nak Lom).]]>

<![CDATA[Astronomical Instruments or Astronomy is a scientific icon that is clear evidence of the development of Astronomy in classical Western and Islamic civilization. Even though the classical Falak instrument is simple, it holds extraordinary scientific treasures. Rubu' Mujayyab is an instrument used by humans to observe and calculate the positions of celestial bodies before telescopes and logarithm tables were invented. In the current era of technological development, Classical Falak Instruments such as the Rubu' Mujayyab need to be developed and adapted to technological advances into software or digital applications in order to continue to exist. This research aims to design the Javascript-based Rubu' Mujayyab application and determine the results of functionality testing and evaluation of the Javascript-based Rubu' Mujayyab digital application. This research was conducted using the Research and Development method. In this research, the classical astronomical instrument was digitally developed using the JavaScript programming language. The Falak instrument developed is Rubu' Mujayyab. This instrument is a classic astronomical instrument which is still relevant to current conditions and is widely used in studying astronomy in Madrasas, Islamic boarding schools and Islamic universities. After the digital application of the classic astronomical instrument was created, it was then validated with an instrument validation sheet by an Expert Researcher from Imah Noong, Lembang, namely Hendro Setyanto, as well as testing the functionality of the two applications. The result is a classic digital falak application, namely rubu' al-mujayyab itself. Apart from that, based on the results of functionality tests by Expert Researchers, it was found that this digital application can run and function well according to the function of the physical instrument.]]>
