Abstract

In the era of the industrial revolution 4.0, astronomers as well as modern society in general cannot turn away from the reality of virtual life. People get information, read and study any knowledge is very easy because everything is available in their hands. Faced with this condition, what about astronomy scholarship? Amid the assumption that astronomy and experts are very rare. So astronomers are demanded to be able to adapt and develop themselves with 'literacy' technology to be able to package the astronomy knowledge and present its content to the public easily and to construct it in digital form. Why does this virtual reality have to be faced and how to deal with it? Associated with efforts to answer the needs of the public about astronomical scholarship in virtual reality, various innovations and creativity of astronomers emerged in the form of digitizing material, books (books) and astronomical applications. This variety of innovations will increase the interest of millennial students to learn and master it. Through this paper,-some of the digitization pattern-, the author will study it with the content analysis method and describe it descriptively-interpretatively. From the results of studies, the author has led to a conclusion that; the first, found a number of patterns of celestial scientific digitalization; from the side of the content, the digital astronomical material consists of the calculation of qibla direction, prayer time, the beginning of the month and eclipse and the practice of its determination, from the media aspect, the astronomy knowledge is presented through social media, such as facebook, instagram, whatsApp and youtube; through website-based media, such as bimasislam.kemenag.go.id, and if.walisongo.ac.id., in the form of smartphone applications, such as digital falak, mizwandroid, qiblat, usholli and so on. While the design of the presentation is varied, in the form of text, video, images and pdf. The second, each of these patterns has made a valuable contribution to the virtual learning of astronomy for millennial society in the current era of the industrial revolution 4.0.

Abstract

In Indonesia there are still often differences in the determination of the beginning of the Hijri month (Kamariah). This is due to the difference between the concept of rukyatul hilal and wujudul hilal is use by the largest religious organization in Indonesia. It is know from several literature sources that Nahdlatul Ulama applies the concept of rukyatul hilal, while Muhammadiyah applies the concept of wujudul hilal. Both have advantages and disadvantages of each. In addition, both of them also apply the concept of wilayatul ḥukmi enforces the initial determination of the Hijri month for a particular jurisdiction, it is valid for a country or government. Following up on this matter, this study wanted to describe the relevance between the concepts of rukyatul hilal and wujudul hilal in the implementation of the wilayatul ḥukmi concept. Problems related to wilayatul ḥukmi will occur if in a hilal area it cannot be seen when the rukyatul hilal process or in a new hilal area has not been realized when applying the wujudul hilal concept. Moving on from the above problems, the question arises as to how the concept of wilayatul ḥukmi is able to accommodate these two concepts, where the jurisdiction included in the reality does not meet the criteria to enter the beginning of the new month. On the other hand, this study also wants to uncover the advantages and disadvantages between the concept of rukyatul hilal and wujudul hilal in the current era, with the hope of being able to provide positive criticism in building common ground for the benefit of the people.  Di Indonesia masih sering terjadi perbedaan dalam penetapan awal bulan Hijriah (Kamariah). Hal ini karena adanya pebedaan antara konsep rukyatul hilal dan wujudul hilal yang digunakan oleh organisasi keagamaan terbesar di Indonesia. Diketahui dari beberapa sumber pustaka bahwa Nahdlatul Ulama menerapkan konsep rukyatul hilal, sedangkan Muhammadiyah menerapkan konsep wujudul hilal. Keduanya mempunyai kelebihan dan kekurangan masing-masing. Selain itu, keduanya juga menerapkan konsep wilayatul ḥukmi yang memberlakukan penetapan awal bulan Hijriah untuk satu wilayah hukum tertentu, yakni untuk suatu negara atau pemerintahan. Menindaklanjuti hal tersebut, penelitian ini ingin mendeskripsikan relevansi antara konsep rukyatul hilal dan wujudul hilal dalam implementasi konsep wilayatul ḥukmi. Permasalahan terkait wilayatul ḥukmi akan terjadi apabila di suatu wilayah hilal tidak dapat terlihat ketika proses rukyatul hilal atau di suatu wilayah hilal belum wujud bilamana menerapkan konsep wujudul hilal. Beranjak dari permasalahan di atas akan timbul pertanyaan bagaimana konsep wilayatul ḥukmi ini mampu mengakomodir kedua konsep tersebut, di mana wilayah hukum yang masuk didalamnya dalam realitanya belum memenuhi kriteria untuk masuk awal bulan baru. Di sisi lain, penelitian ini juga ingin mengungkap kelebihan dan kekurangan antara konsep rukyatul hilal dan wujudul hilal di era saat ini, dengan harapan mampu memberikan kritik positif dalam membangun kesamaan pandangan demi kemaslahatan umat.Kata Kunci: Rukyatul Hilal, Wujudul Hilal, Wilayatul Ḥukmi

Currently, the book still refferenced as the praying schedule determination in some areas in West Sumatra. The main issues of this research are to answer abot how the hisab method of all the time of praying schedule by Sa’aduddin Djambek as well as how to analyze this method. Then, the objectives of the research is to describe the calculation method of all the time praying schedule and analyze this method. The result shows that the determination of the beginning of praying schedule in Indonesia it mostly close or even equal to the result of modern hisab. Some factors causes the diffences of hisab result is method, formula, and data. Nevertheless, the differences are not that much, it is only 1 to 2 minutes. Besides, the all time praying schedule sometimes sooner and later than hisab result of praying schedule calculated by contemporary hisab method. Therefore, it can be assumed that the all time praying schedule is accurat hisab method, since its result close or even equal to contemporary hisab method. Moreover, its calculation is more simple and understandable.Keywords: Sa’aduddin Djambek’s Hisab, Praying Schedule, All the Time Abstrak Perkembangan ilmu Falak saat ini tidak terlepas dari keterlibatan ahli falak sebelumnya, seperti Sa’aduddin Djambek yang terkenal dengan karyanya “Pedoman Waktu Shalat Sepanjang Masa”. Sampai saat ini kitab tersebut masih menjadi rujukan dalam penentuan awal waktu shalat di beberapa wilayah di Sumatera Barat. Pokok permasalahan dalam makalah ini adalah bagaimana metode hisab awal waktu shalat sepanjang masa menurut Sa’aduddin Djambek dan bagaimana analisis terhadap metode hisab waktu shalat sepanjang masa. Adapun tujuan dari penulisan ini adalah untuk mendiskripsikan hisab awal waktu shalat sepanjang masa dan menganalisis metode hisab awal waktu shalat sepanjang masa. Analisis yang diperoleh dari metode Hisab tersebut, bahwa  dalam penetapan awal waktu shalat wajib untuk wilayah Indonesia, jadwal waktu shalat sepanjang masa  banyak yang mendekati bahkan ada yang sama dengan hisab kekinian.  Faktor-faktor yang menyebabkan terjadinya perbedaan hasil hisab tersebut karena disebabkan oleh cara-cara, rumus dan data yang digunakan. Walaupun demikian, perbedaan-perbedaan hasil yang didapatkan tidak mencapai pada takaran waktu yang cukup jauh, tapi hanya terpaut pada menit saja  dengan selisih antara 1-2 menit. Selain itu jadwal shalat sepanjang masa kadang lebih awal dan kadang lebih akhir daripada jadwal shalat hasil perhitungan dengan rumus hisab kontemporer.[MIH1]  Sehingga dengan demikian dapatlah dikatakan bahwa metode hisab waktu shalat sepanjang masa merupakan metode hisab yang akurat  dan hasil hisab mendekati hasil yang sama.dengan hisab kekinian.

Abstract The science of Islamic astronomy that develops in the Indonesian archipelago is quite diverse with various methods of approach and defined criteria. Along with the development of science and technology, the works of Indonesian archipelago mufti on science of Islamic astronomy seemed to have sunk without a trace. There are only a few that still exist and can be enjoyed by researchers and observers of science of Islamic astronomy. The rest has not been touched to be developed, let alone to be reconstructed. Reconstruction and reexamination of the science of Islamic astronomy by the previous mufti of Indonesian archipelago is very important for several things. As an appreciation for the services of the author, preserve and develope the scientific treasures. The writer examines this issue with the library research method. First, the writer traces the works of Indonesian mufti in an organized manner in each region. Second, classify these works according to the criteria of taqribī or taḥqīqī. Third, reconstruct the works that belong to the taqribī category into the taḥqīqī category. And fourthly, rewrite the works referred to as a form of preservation of scientific treasures in the field of Islamic astronomy. The results that will be obtained from the four stages above are, first; knowing how many previous works of Mufti of Indonesian archipelago in the field of Islamic astronomy in each region shows that Mufti of Indonesian archipelago  had a high concern over  the development of islamci astronomy at that time. Second; You will find a comparison of the number of works that belong to the taqribī and taḥqīqī categories. Third; By reconstructing the works of the taqribī category into the taḥqīqī category, it will further foster enthusiasm for carrying out scientific studies which are verybenefical in order to increase knowledge of Islamic astronomy. And fourth; The preservation of the scientific treasures of the Indonesian archipelago created by previous scholars of the Indonesian archipelago which can be used as a reference for future research.Keyword: archipelago scholar, islamic astronomy, reconstructionAbstrakIlmu falak yang berkembang di nusantara cukup beragam dengan berbagai metode pendekatan dan kriteria. Seiring dengan perkembangan ilmu pengetahuan dan teknologi, karya-karya ulama nusantara tentang ilmu falak seakan tenggelam tanpa bekas. Hanya ada beberapa yang masih eksis dan dapat dinikmati oleh para peneliti dan pemerhati ilmu falak. Selebihnya belum tersentuh untuk dikembangkan apalagi direkonstruksi. Rekonstruksi dan penelahaan kembali terhadap ilmu falak karya ulama nusantara terdahulu sangat penting dilakukan untuk beberapa hal. Sebagai penghargaan atas jasa para mu’allif, melestarikan dan mengembangkan warisan khazanah keilmuan. Penulis mengkaji hal ini dengan metode library research. Pertama penulis menelusuri karya-karya ulama nusantara secara terorganisir dimasing-masing daerah. Kedua melakukan klasifikasi karya-karya tersebut sesuai dengan kriteria taqribī atau taḥqīqī. Ketiga merekonstruksi karya yang masuk kategori taqribī menjadi kategori taḥqīqī. Dan keempat menulis kembali karya-karya dimaksud sebagai bentuk pelestarian khazanah keilmuan dibidang ilmu falak. Hasil yang akan diperoleh dalam melakukan empat tahapan diatas adalah, pertama; mengetahui seberapa banyak karya-karya terdahulu ulama nusantara dalam bidang ilmu falak di masing-masing daerah yang menunjukkan bahwa ulama nusantara memiliki perhatian yang tinggi terhadap berkembangnya ilmu falak pada saat itu. Kedua; akan ditemukan perbandingan jumlah dari karya tersebut yang termasuk kategori taqribī dan taḥqīqī. Ketiga; dengan merekonstruksi karya kategori taqribī menjadi kategori taḥqīqī semakin menumbuhkan semangat untuk melakukan kajian-kajian keilmuan falak yang sangat bermanfaat dalam rangka meningkatkan pengetahuan. Dan keempat; lestarinya khzanah keilmuan falak hasil karya ulama nusantara terdahulu yang dapat dijadikan rujukan untuk penelitian-penelitian di masa yang akan datang.Kata kunci: ulama nusantara, ilmu falak, rekonstruksi
