Indikator Penciri Penanggalan Hijriah pada Pergerakan Pasang Surut
No full textRhythmic movement of the tides follow the movement of the moon,as the dominant component of which has a rhythmic, should the movement of tidal inform month trip in the form of style variations of tide generating force (GPP) which indicates the time in the Hijra calendar. This article aims to determine the indicator of the tidal movement indicating the time of the Hijri calendar. The timing of slack water (t sw) the movement receded into pairs (tsw s) in peak II relatively consistent for the three months of data were analyzed tidal movement. Consistency is shown on the results of the statistical analysis by comparing the Probability (Pr) to the Wilks’ Lambda ( ) is very small(<0.0001) which means that the time of slack water (t sw) can be a primary identifier in determining the Hijra calendar. Further research is needed to determine the time point t SWS belt of a general nature in order to facilitate the determination of the Hijra calendar through the movement of the tides.DOI: 10.15408/ajis.v17i2.5686</p
Posisi komponen GPP terhadap variasi konstituen harmonik pasang surut bulan Muharram di Stasiun Sabang
No full textThe movement of celestial bodies produces a variation of a gravitational gradient as a tidal generation force (GPP). Position Sabang Station, declination maximum and position lunar month of Muharram aka n generate harmonic constituent character identifier of GPP, where the water level is the sum of the amplitude of harmonic constituent that generated at a certain time.This research is to determine the variation of harmonic constituents and identify the character of harmonic constituents of GPP component position characterization in Muharram month. The results show Katrakteristik tidal movement beginning of the month of Muharram in Sabang Station occurred 1-2 hours after ijtimak.. Value riding dominant water derived from the value of Mean Sea Level (> 52%), and the dominant contribution hamonik constituents derived from component M 2 (28 - 33%). Harmonic constituents M 2 does not show the position of the moon in Muharram, while the position of the sun is reflected in the constituent phase harmonic S 2.
Ethno Tide Masyarakat Pesisir Indonesia Timur Dalam Menentukan Penanggalan Hijriah
Get PDFMasyarakat Indonesia timur menentukan penanggalan hijriah selain melihat ukuran cakram bulan, mereka juga mengamati perubahan pasang surut terhadap waktu shalat fardhu. Pengetahuan mereka dalam menerjemahkan fenomena pasang surut disebut dengan ethno-tide. Diperlukan identifikasi karakter pasang surut sebagai buktian kebenaran ilmiah dari ethno tide tersebut. Ethno tide masyarakat indoinesia Timur adalah suatu kebenaran ilmiah. Konsistensi waktu terjadinya Tsw terhadap waktu shalat relatif kecil (deviasi < 44 menit. Waktu terjadinya slack water (TSW), merupakan indikator penciri dari umur bulan dan effektif (sederhana) dalam menentukan penanggalan hijriah. Waktu Tsw pada peak II (siang hari) lebih effektif mengidentifikasi umur bulan dibandingkan Tsw yang terjadi di peak I (malam hari). Setiap TSw yang terjadi pada rentang waktu shalat fardhu menginformasikan umur bulan dalam satu fase bulan tertentu. Umur bulan dari fase bulan baru (BB) ke fase kuartil 1 (BB-KW1) untuk penanggalan 1 – 5 H lebih efektif diperlihatkan Tsw-SI yang terjadi antara Shalat Ashar dan Isha. Slack water untuk penanggalan di fase kuartil I (5 – 10 H) terjadi dalam rentang shalat shubuh ke Ashar oleh Tsw-SII. Rata-rata pergeseran Tsw harian awal bulan hijriah sebesar 48 menit yang mendekati pergeseran saat fase purnama (49 menit). Pergeseran harian saat fase kuartil 1 (01:23) lebih kecil dibandingkan kuatil 2 (02:50) sedangkan saat fase akhir bulan (bulan mati) sebesar 53 menit
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
ETHNOOCEANOGRAPHY DAN TITIK TEMU ASPEK SYAR’I DALAM PENENTUAN AWAL BULAN RAMADHAN DAN SYAWAL OLEH JOGURU KESULTANAN TIDORE
Get PDFEthnooceanography and the intersection of shar'i aspects to determination of the early of Ramadan and Shawwal by Joguru Sultanate of Tidore. The determination of the early of the new month of Ramadan and Shawwal was very important for Muslims because it is related to the time of worship. Judge syara 'The Sultanate of Tidore (Joguru) has long applied the method of determining the early month of Hijri (Ramadan and Shawwal) through tidal movement observed on "akebai" included in ethooceanography and called Joguru Method (MJ). Hilal that has never been seen in Tidore and its surrounding areas in the long-term cycle of moon (34 years) caused its early moon to be inapplicable due to non-fulfillment of the requirement of hisab (hadith). MJ makes observation (rukyat) change of tidal movement on "akebai" is "ijtihād". The appropriateness of the scientific aspects of ethnoocaenography and the intersection of the shar'i aspects make it a comparative method of determining the beginning of the new month of Hijri in astronomy (hilāl). Required the expansion of the meaning of the “hilāl” as an indicator of the beginning of the month of the Hijri calendar.

Ethnooceanography dan titik temu aspek Syar’i dalam penentuan awal bulan Ramadhan dan Syawal oleh Joguru Kesultanan Tidore. Penentuan awal bulan baru Ramadhan dan Syawal sangat penting bagi umat Islam karena berkaitan dengan waktu ibadah. Hakim syara’ Kesultanan Tidore (Joguru) telah lama mengaplikasikan metode penentuan awal bulan baru Hijriah (Ramadhan dan Syawal) melalui pergerakan pasang surut yang terpantau pada “akebai” termasuk dalam ethooceanography dan disebut dengan Metode Joguru (MJ). Hilal yang tidak pernah terlihat di wilayah Tidore dan sekitarnya selama siklus jangka panjang (34 tahun) menyebabkan hisab awal bulan tidak dapat diaplikasikan akibat tidak terpenuhinya persyaratan hisab (hadis). MJ melakukan pengamatan (rukyat) perubahan tinggi air pada “akebai” adalah “ijtihad”. Terdapat kesesuaian aspek sains dari ethnoocaenography serta titik temu aspek syar’i yang menjadikan MJ berpotensi sebagai metode utama sekaligus sebagai metode pembanding dari metode umum dalam penentuan awal bulan baru Hijriah. Diperlukan perluasan makna kata “hilal” sebagai indikator awal bulan baru penanggalan Hijriah
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Variation of Tidal Range Based On Hijra Calendar And Its Relation With Ethno-Oceanography of The Sama Tribe In Eastern Indonesia
No full textBased on Ethno–Oceanography of the Sama tribe in Eastern Indonesia, they measured and determined tidal range when Sya’ban taking place. Why do they do so? The questions and objective of this study were intended to respond the scientific fundamental of Ethno-Oceanography of the Sama tribe. In order to achieve the objective of this study, the tidal range value in each Hijra month was compared and analyzed statistically (ANOVA). Tidal Analysis results showed that the tidal range at Sya’ban was higher and the deviation was lower than the other months. Moreover, ANOVA results showed that Sya’ban was significantly different (P<0.05) on Highest High Water Level (HHWL) throughout Hijra month.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
