AbstrakArtikel Info Kemajuan ilmu pengetahuan dan teknologi memberi dampak yang luar biasa diberbagai sendi kehidupan. Indonesia yang mayoritasnya beragama Islam, sebagian besar masyarakatnya masih melakukan pengamatan hilal untuk memastikan masuknya awal bulan baru hijriah. Penngamatan yang dilakukan bermacam-macam, dari yang sederhana hanya menggunakan mata telanjang hingga pengamatan yang sudah menggunakan berbagai teknologi penunjang. The Islamic Science Research Network (ISRN) Universitas Muhammadiyah Prof. DR. HAMKA teah membangun sistem pengamatan hilal yang menggunakan teknologi terkini yang terdiri dari teleskop William Optic Zenith Star 71ED, kamera CCD Skyris 274M, dudukan teleskop tipe iOptron CEM60, dan filter Baader 685nm. Sebagai instrumen pembantu, sistem teleskop ditambah dengan baffle untuk menapis kuatnya cahaya Matahari pada saat pengamatan.
Direct learning has migrated into online learning since the education sector is affected by the COVID-19 pandemic. One alternative to the online learning method is by implementing an online cooperative-jigsaw or virtual jigsaw. The study explores students' perceptions of virtual Jigsaw learning as an alternative model during the COVID-19 pandemic. The data were obtained through questionnaires given to the 25 students of science student-teachers at State Islamic University who have implemented the model. The perceptions to be seen are related to interest, effectivity based on the advantages and difficulties they have experienced, and syntax implementation during online learning using the Jigsaw model. The result indicates that most students showed positive perceptions and interest, also gained more advantages rather than difficulties. Moreover, the Jigsaw syntax is well-applicable though it runs online.
This paper discussed the implementation of the new MABIMS hilāl visibility criteria in the unification of the Hijriyah calendar in member countries (Malaysia, Brunei, Indonesia and Singapore). This research uses the approach of Astronomy and Grindle's theory of policy implementation. The data source comes from the MABIMS Muzakarah results document and related articles. The research results indicate that the new MABIMS moon crescent visibility criteria are part of a public policy that, in its implementation, requires two mutually supportive variables. First, the content of the policy in the form of the moon crescent visibility criteria (3⁰; 6.4⁰) was accepted by all member countries through the signing of an ad referendum on 8 December 2021. This acceptance will receive public support if it is beneficial to time management. Second, the context of implementation is carried out in stages by taking into the characteristics of the institutions involved in preparing the Hijriyah calendar. At the practical level, the policy can be well received by the public, except in Indonesia, which still faces obstacles. This is due to the policy in the three countries being carried out on a top-down basis, while in Indonesia, it is carried out on a bottom-up basis. Furthermore, determining of Ramadan, Shawwal, and Zulhijjah are still waiting for confirmation of the sighting of the moon (ru’yah). It related to the domination of ru’yah, and a strong distinction between the function of the calendar in civil administration and worship practice. Abstrak Makalah ini membahas penerapan kriteria baru visibilitas hilalMABIMS dalam penyatuan penanggalan Hijriyah di negara-negara anggota(Malaysia, Brunei, Indonesia dan Singapura). Penelitian ini menggunakanpendekatan penerapan kebijakan Astronomi dan teori Grindle. Sumber databerasal dari dokumen hasil Muzakarah MABIMS dan artikel terkait. Hasilpenelitian menunjukkan bahwa kriteria baru visibilitas hilal MABIMS merupakanbagian dari kebijakan publik yang dalam pelaksanaannya membutuhkandua variabel yang saling mendukung. Pertama, isi kebijakan berupa kriteriavisibilitas bulan sabit (3⁰; 6.4⁰) diterima oleh seluruh negara anggota melaluipenandatanganan referendum pada 8 Desember 2021. Penerimaan ini akanmendapat dukungan publik jika bermanfaat hingga manajemen waktu. Kedua,konteks pelaksanaannya dilakukan secara bertahap dengan memperhatikankarakteristik lembaga yang terlibat dalam penyusunan penanggalan Hijriyah.Pada tataran praktis, kebijakan tersebut dapat diterima dengan baik olehmasyarakat, kecuali di Indonesia yang masih menghadapi kendala. Hal inidisebabkan kebijakan di ketiga negara dilakukan secara top-down, sedangkan diIndonesia dilakukan secara bottom-up. Selanjutnya, penentuan awal Ramadan,Syawal dan Zulhijah masih menunggu konfirmasi penampakan hilal (rukyah).Ini terkait dengan dominasi ru’yah, dan perbedaan yang kuat antara fungsipenanggalan dalam administrasi sipil dan praktik ibadah.
Penelitian ini bertujuan untuk mengukur prestasi hasil belajar dalam kegiatan pelatihan SAILS-UINSA di Fakultas syariah dan Hukum dengan menggunakan Mann-Whitney. Metode penelitian yang digunakan yaitu kuantitatif, dengan pengumpulan data menggunakan angket, data dianalisis secara diskriptif dan menggunakan Mann-Whitney. Berdasarkan hasil analisis terhadap data yang telah dikumpulkan, diperoleh kesimpulan bahwa pelatihan SAILS-UINSA di Fakultas Syariah dan UINSA secara diskripsi memberikan kenaikan rata-rata hassil prestasi belajar antara sebelum dan sesudah pelatihan yaitu sebesar 1,14, dengan peserta yang mengalami kenaikan prestasi belajar sebesar 57,14%. Namun, jika dianalsiis dengan mann-whitney pelatihan tersebut tidak memberikan kenaikan prestasi belajar.
Early fajr time research was carried out by various parties with various techniques, one of which was using a sky quality meter (SQM) photometric tool. Observational data from various regions that have varying night levels result in a varying early fajr time as well. By paying attention to the effect of sky quality represented by the night level at the observation location, this research wants to answer whether the 20 mpsas night level limit is ideal data by looking at the correlation coefficient between night level and the turning point solution. From 1068 data with varying night levels, the correlation coefficient ( ) between the night level and the turning point solution is 0,42 which means there is an effect, while for data with a minimum night level of 20mpsas the correlation coefficient is 0,07 which means there is no influence. Based on the results of the analysis, the night level of 20mpsas can be the minimum limit for conducting an ideal early fajr time research. From 241 ideal observation data from 6 LAPAN observation stations, early fajr time presents when the Sun's elevation angle is -16,51°. Early fajr time is also the beginning of subuh prayer time, with its standard used in Indonesia, which is -20° or 3,49° different from the analysis results, if it is converted there is a difference of 13 minutes 57 seconds.
Research using a simple photometric device, namely the Sky Quality Meter (SQM), is widely carried out for various purposes. Research of determining subuh prayer time using SQM in Indonesia is also widely carried out, by various groups and produces observational data from various locations. Each observation location has a different sky quality, the quality of the sky is represented by the night level obtained from observations using SQM. The beginning of subuh prayer time is obtained by determining the inflection point of the SQM data. From 460 observational data from LAPAN Pasuruan station and LAPAN Pontianak station, to determine the night level that represents the quality of the sky and the turning point solution, this research uses product moment correlation. The calculation shows that there is a correlation between the night level and the turning point solution with r = -0.77 in the strong or high correlation category, besides that the correlation pattern shows a negative correlation or reverses which indicates that the higher the night level, the deeper the turning point results. This also shows that researchers who want to make observations with SQM to determine turning points should be done in locations that have good or high night levels. Keywords: subuh prayer time, SQM, correlation, night level, turning point. Abstrak: Penelitian menggunakan alata fotometri sederhana yaitu Sky Quality Meter (SQM) marak dilakukan untuk berbagai keperluan. Penelitian awal waktu subuh menggunakan SQM di Indonesia juga marak dilakukan, oleh berbagai kalangan dan menghasilkan data pengamatan dari berbagai lokasi. Tiap-tiap lokasi pengamatan memilki kualitas langit berbeda, kualitas langit direpresentasikan oleh level malam yang diperoleh dari hasil pengamatan menggunakan SQM. Awal waktu subu diperoleh dengan menentukan titik belok dari data SQM. Dari 460 data pengamatan yang berasal dari stasiun LAPAN Pasuruan dan stasiun LAPAN Pontianak, untuk menentukan antara level malam yang merepresentasikan kualitas langit dengan solusi titik belok, penelitian ini menggunakan korelasi product moment. Perhitungan menunjukkan adanya korelasi antara level malam dengan solusi titik belok dengan r= -0.77 masuk pada kategori korelasi yang kuat atau tinggi, selain itu pola korelasinya menunjukkan korelasi negatif atau berbalik arah yang menunjukkan bahwa makin tinggi level malam maka hasil titik belok akan semakin dalam. Hal ini juga menunjukkan bahwa para peneliti yang ingin melakukan pengamatan dengan SQM untuk menentukan titik belok, sebaiknya dilakukan di lokas-lokasi yang memiliki level malam baik atau tinggi. Kata kunci: waktu subuh, SQM, korelasi, level malam, titik belok.
Now, astronomical observations including hilal observations are easier and simpler because of instruments equiped with computerbased technology. One of them is a telescope that is equipped by a automatical motor drive and computerized. Telescope control is now easier to do with applications based on open source operating systems, one of them is KStars application. With Meade LX-600 telescope owned by the departement of Ilmu Falak, Islamic Studies and Law Faculty UIN Sunan Ampel Surabaya, a control system was built using the KStars application based on open source, which has the advantage of no need to install additional drivers for connectivity with cables.
