Hisab dan rukyat, hakikatnya, adalah cara untuk mengetahui pergantian bulan. Kajian ini memperlihatkan beberapa temuan. Pertama, korelasi antara hadis Kuraib dan terjadinya perbedaan penetapan awal Ramadan, Syawal, dan Dzul Hijjah di Indonesia. Kementerian Agama Republik Indonesia telah menetapkan bahwa Indonesia secara keseluruhan menjadi satu wilayah hukum (wilayatul hukmi). Kedua, tentang keberhasilan rukyat al-hilal di satu kawasan yang diberlakukan bagi kawasan lain di muka bumi. Perlu diketahui bersama bahwa visibilitas pertama hilal tidak meliputi seluruh muka bumi pada hari yang sama, melainkan membelahnya menjadi dua bagian: (1) bagian sebelah Barat yang dapat melihat hilal dan (2) bagian sebelah Timur yang tidak dapat melihat hilal.Hisab and rukyat is a way to know the turn of the month. This study shows several findings. First is the correlation between Kuraib traditions and differences in the determination of the beginning of Ramadan, Shawwal, and Dhul-Hijjah in Indonesia. Ministry of Religious Affairs of the Republic of Indonesia has stated that Indonesia as a whole into a single jurisdiction (wilayatul hukmi). Second, on the success rukyat alhilal in one area that applied to other regions of earth. Important to know that the first visibility of the new moon does not cover the entire face of the earth on the same day, but splitting it into two parts: (1) part of the West to see the new moon, and (2) part of the East were not able to see the new moon.

Evidence has accumulated over the years indicating that the moon influences some aspects of the reproductive activity in animals and humans. However, little is known about the influence of the lunar cycle on the reproductive performance of cows under tropical conditions, where the environment strongly affects reproduction. This retrospective study was conducted with the aim of assessing the influence of the lunar cycle on some reproductive traits of tropical crossbred cows managed in a pasture-based system. Data from 5869 reproductive records from two commercial farms localized in the Maracaibo Lake Basin of Zulia State, Venezuela, were analyzed. Variables studied were first service conception rate, calving frequency, first postpartum estrous frequency, and pregnancy frequency. In addition to the lunar cycle, the effects of farm, season, and predominant breed were also considered. Data were analyzed using logistic regression and general linear model from SAS. First service conception was affected by lunar phases and predominant breed, but not by farm or season. For frequencies of calving, first postpartum estrus, and pregnancy, there was no main effect of farm, season, and predominant breed, whereas the effect of lunar phases was highly significant. First service conception was significantly greater in waning than in crescent phase of the lunar cycle. Frequencies of calving, first estrus, and pregnancy were highly correlated and showed greater figures around full moon and new moon. In conclusion, lunar cycle influenced first service conception, attaining greater values in the waning phase of the moon cycle. Frequencies of calving, first postpartum estrus, and pregnancy in crossbred cows showed a clear bimodal rhythm, whose greatest values coincided with new moon and full moon.

AbstractVery little is known about the ecology and biology of the smallest marine vertebrates, fishes in the genus Schindleria. Even though over half of named Schindleria species have been identified in the Red Sea, the collection of only very few specimens has been documented. Here, we assessed abundance patterns of nearly two thousand Red Sea long dorsal fin (LDF) adults and found evidence for putative seasonal and spatial differences, likely related to differing habitat and environmental conditions. The highest abundances were outside local seasonal temperature extremes and decoupled from peaks of coral reef fish recruitment. We also found evidence for global trends in abundances related to lunar cycles using our Red Sea data and that from a recently published large collection of specimens from the DANA Expedition (1928–1930). The abundance of adult LDF Schindleria in relation to lunar phases differed significantly, with most Schindleria caught outside the full moon, and mostly during the new moon in the Red Sea and the 3rd quarter moon in the DANA collection. We further suggest that the abundances of Schindleria at coral reefs may be related to reproductive cycles and that these cycles may be timed with the moon as back-calculations of hatch dates from otoliths from the Red Sea significantly resulted after the new moon, making Schindleria the fastest-lived coral reef fish with the shortest generation times. Schindleria could be the most numerous coral reef fish in the world, for which we encourage increased research.

AbstractThe Islamic society has great ties to astronomy. Its main religious customs (start of the Islamic month, direction of prayer, and the five daily prayers) are all related to two main celestial objects: the Sun and the Moon. First, the start of any Islamic month is related to the actual seeing of the young crescent after the new Moon. Second, the direction of prayer, i.e., praying towards Mecca, is related to the determination of the zenith point in Mecca. Third, the proper time for the five daily prayers is related to the motion of the Sun. Everyone in the society is directly concerned by these customs. This is to say that the major impetus for the growth of Islamic astronomy came from these three main religious observances which presented an assortment of problems in mathematical astronomy. To observe these three customs, a new set of astronomical observations were needed and this helped the development of the Islamic observatory. There is a claim that it was first in Islam that the astronomical observatory came into real existence. The Islamic observatory was a product of needs and values interwoven into the Islamic society and culture. It is also considered as a true representative and an integral par of the Islamic civilisation. Since astronomy interested not only men of science, but also the rulers of the Islamic empire, several observatories have flourished. The observatories of Baghdad, Cairo, Córdoba, Toledo, Maragha, Samarqand and Istanbul acquired a worldwide reputation throughout the centuries. This paper will discuss the two most important observatories (Maragha and Samarqand) in terms of their instruments and discoveries that contributed to the establishment of these scientific institutions.

Analysis of the total copper and zinc content of four species of talitrid amphipods, Orchestia gammarellus, O. mediterranea, Talitrus saltator and Talorchestia deshayesii throughout a complete spring/neap tidal cycle failed to reveal any significant effects of moulting upon body copper or zinc in any species. Moulting was synchronized to the lunar cycle only in T. saltator, taking place 5–7 days prior to a new moon. The fact that no significant changes in body metal concentrations took place with the moult cycle is discussed in relation to the use of talitrid amphipods in copper and zinc biomonitoring programmes.

Although graphical methods are in common use by engineers and astronomers, they are less familiar to archaeologists. To portray the rhythm of celestial motions, astronomers often use “elongation” diagrams to show angular distances of moon and planets from the sun on each day of the calendar year.The Maya recognized a zone within which the planets could not be seen because of proximity to the brilliant disk of the sun. The moon cannot be seen on the day of conjunction with the sun, and is generally invisible on the day before and the day after this “new moon day.” The three consecutive days in the lunar table of the Dresden Codex may represent the 3-day phase of moon disappearance.

Madidihang/yellowfin tuna merupakan salah satu jenis ikan tuna ekonomis penting bagi industri perikanan di Indonesia dengan kontribusi hasil tangkapan yang terbanyak. Penelitian ini bertujuan untuk mengetahui pengaruh fase bulan terhadap waktu mulai tebar pancing dan laju tangkap madidihang pada armada rawai tuna. Pengumpulan data dilakukan oleh pemantau ilmiah pada armada rawai tuna yang sebagian besar berbasis di Pelabuhan Benoa, Bali mulai Agustus 2005 hingga Juni 2014. Daerah penangkapan ikan dari armada rawai tuna yang diambil datanya berada di lokasi (lintang dan bujur) 9°-16° LS hingga 109°-120° BT. Analisis anova satu arah dan tes Tukey dilakukan untuk mengetahui pengaruh fase bulan terhadap waktu mulai tebar pancing dan laju tangkap madidihang. Total sebanyak 60 trip dan 1.467 hari operasi penangkapan armada rawai tuna dilakukan dalam penelitian ini. Analisis statistik anova satu arah menunjukkan bahwa terdapat pengaruh yang nyata pada fase bulan terhadap waktu mulai tebar pancing (p<0,05). Selanjutnya, tes Tukey menunjukkan bahwa waktu mulai tebar pancing pada saat bulan purnama dimulai pada pukul 9:00 pagi hari. Waktu ini lebih lambat sekitar 2 jam dari pada waktu mulai tebar pancing pada ketiga fase bulan lainnya (perbani awal, perbani akhir dan bulan baru) yang dilakukan sekitar pukul 7:00 pagi hari. Analisis statistik anova satu arah juga menunjukkan terdapat perbedaan yang nyata antar fase bulan terhadap laju tangkap madidihang (p<0,05). Selanjutnya, tes Tukey menunjukkan bahwa laju tangkap pada saat bulan baru dan perbani awal sebesar 0,13 ekor/100 mata pancing atau lebih besar dibandingkan nilai laju tangkap pada saat purnama dan perbani akhir yang hanya sebesar 0,09 ekor/100 mata pancing. Yellowfin tuna is one of the most economically important species for fisheries industry in Indonesia. The objectives of this study are to investigate the effect of lunar phase to the set time start and catch rate of yellowfin tuna on tuna longline vessels. Data collected by scientific observer on tuna longline vessels mainly based in Benoa Port, Bali from August 2005 to June 2014. Fishing ground of sampled longline tuna located from 9°-16° S to 109°-120° E. One-way anova analysis and Tukey test conducted to examine the effect of lunar phase to the set time start and catch rate of yellowfin tuna. A total of 60 trips and 1,467 fishing days of longline tuna fishing vessels operation have been sampled for in this study. One-way anova analysis showed that there was a significant difference of lunar phase to the set time start (p<0.05). Furthermore, Tukey test showed that the starting time for setting during the full moon begins at 9:00 am. Its time was around 2 hours slower than the start of setting of the other three moon phase (first quarter, last quarter and new moon) which start around 7:00 am. One-way anova analysis also showed that there was a significant difference of lunar phase to catch rate of yellowfin tuna (p<0.05). Furthermore, Tukey test confirmed that hook rate on new moon and first quarter was 0.13/100 hooks or 0.4 bigger than hook rate on full moon and last quarter with only 0.09/100 hooks.
