Reverse Osmosis plant adalah suatu permesinan bantu yang dioperasikan
untuk mengubah air laut menjadi air tawar dengan menggunakan prinsip tekanan.
Tujuan dari perawatan Reverse Osmosis adalah untuk. 1) Untuk mengetahui sebab
mengapa terjadi penurunan produksi air tawar, 2) Untuk mengetahui upaya apa saja
yang harus dilakukan untuk mengatasi penurunan produksi air tawar pada Reverse
Osmosis. Metode yang digunakan dalam skripsi ini adalah metode Deskriptif
Kualitatif dengan teknik SHEL dan USG sebagai metode untuk menentukan
penyebab dan upaya untuk menanggulanginya.
Penurunan produksi air tawar pada reverse osmosis disebabkan oleh rusaknya
filter pasir yang disebabkan oleh tertahanya pipa outlet filter karena banyaknya
endapan yang ada di filter pasir dikarenakan air laut yang kotor dan kurangnya
perawatan pada filter pasir.
Dari hasil penelitian ini disimpulkan outlet filter pasir (prioritas 1),
Komunikasi yang buruk (prioritas 2), Air laut kotor (prioritas 3), Kurang
berjalannya planned maintenance sistem (PMS) diatas kapal khusnya pada reverse

dan perawatan komponen Reverse Osmosis secara berkala. Dan Sebaiknya
perusahaan segera melengkapi dan mencarikan manual book yang sesuai dengan
permesinan yang ada di kapal agar seluruh crew tidak mengalami kesulitan dalam
melaksankan perawatan permesinan
Intellectual property laws and Islam in Malaysia.
No full textPhDThis study is undertaken on the premise that Islam and Islamic law is to be taken into
serious consideration in any future legislative reform of laws in Malaysia. Islam being
the religion of the country and the strong religious sentiment of the Muslims (who
form the majority in Malaysia) cannot be overlooked or dismissed lightly by the
legislators in Malaysia. Reformation of intellectual property laws is timely, as we are
now approaching to the dateline set by GATF-Trips agreement which aim is to
improve our standard of intellectual property protection. This study seeks to analyze
and evaluate the current legislation pertaining to intellectual property in Malaysia in
terms of the philosophy and rules governing the existence, ownership and exercise of
these rights and their consistency and inconsistency with Islam and Islamic law. The
main objective of this study is to prove that a coherent and logical conceptual
framework of ownership of intellectual property can be derived from an Islamic
perspective which not only offers the basis of rights but also defines the scope of
these rights. From the point of ownership of rights, support can be obtained from the
normative framework of property rights within the traditional classification of 'mal'
(property) and 'haqq al-milkiyyah' (ownership rights) under Islamic law. From the
point of exercise of rights, the exact scope can be defined from the analysis of
fundamental concepts which have been developed by Muslim jurists. It has been
established that Islam and Islamic law offers a sound and systematic paradigm, which
in deeper analysis, can satisfy both our current obligations under international
treatises, as well as our responsibility to practise our religion to the fullest
Prediksi Pergerakan Bayangan Bumi Saat Terjadi Gerhana Bulan Menggunakan Ephemeris Hisab Rukyat
Get PDFIn this era, the prediction of lunar eclipse can be determined accurately with the astronomical data based algorithm. Usually, the prediction just compute the position and time of lunar eclipse without considered the movement of Earth shadow in the begginning to the end of eclipse. In this article the author explain how is the concept, algorithm, and analysis about the movement of Earth shadow on going lunar eclipse in certain local coordinate point, using the data from Ephemeris Hisab Rukyat
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
Astrology in literature: how the prohibited became permissible in the Arabic poetry of the mediaeval period
Get PDFThis thesis is concerned to position the art of astrology within the context of classical Arabic poetry, primarily by investigating and elucidating attitudes to the notion of
qadar (fate) and the ideology in which it was embedded. These attitudes were revelatory of the broader world view of the Arabs of those periods, and their shifts from those held in the pre-Islamic and early Islamic eras tell us a good deal about the importance given to the nature and role of fate and about the various understandings of its influence. The pre-Islamic Arab's notion of qadar was in some ways similar to that of the early Muslims: both emphasised predetermination and the irresistible power of fate. But while the jahilf (Pre-Islamic) Arabs identified fate with the malign power of dahr (Time), the Muslims believed the power of fate lies in the hands of God the
Omnipotent, who alone is responsible for the fate of the whole universe. Thus the astrology of the pre-Islamic era was one aspect of divination (kihana) and claimed to be
able to reveal in advance an individual's destiny, which could be avoided by taking certain precautions. These precautions, however, were considered effective only in
relatively trivial cases; they were useless in the areas of major impact: a person's happiness or misery (shaqiiwa aw sa ada), sustenance (rizq) and one's term (ajal), the
three inevitable and irresistible manifestations of fate. In the Islamic period not only these major aspects of life are governed and controlled by the Omnipotent; the destiny
of the universe, in even its most minute details, is determined and controlled by God alone. Astrology was considered to be of no value whatsoever, and its practitioners were subject to the death penalty. These two irreconcilable views are evident in early Islamic poetry, which reflected clearly the response of poets, and society, to astrology from the perspective of qadar.
When the orthodox caliphate was replaced by dynastic rule the status of astrology was changed dramatically. The idea that the stars, as indicators, play a role in the life of
human beings found popowerful supporters in some governors of the Islamic world, who allowed astrology to fulfil a public function regardless of the hostility of the official
religion of that society. This social phenomenon generated rich material of a controversial character in the realm of literature. Investigating the factors, motivations
and impact of mediaeval political, theological and philosophical attitudes to astrology, in relation to the notions of free will and predestination, is the concern of this study
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
Kulminasi Bulan sebagai Acuan Titik Koordinat untuk Penentuan Arah Kiblat
No full textTitik koordinat merupakan komponen penting dalam perhitungan ilmu falak. Salah satu metode untuk mencari titik koordinat adalah dengan memanfaatkan kulminasi Bulan. Metode ini masih banyak yang belum mengetahui, oleh karena itu penulis mencoba mengkaji metode tersebut, dengan membuktikan tingkat akurasinya terhadap perhitungan arah kiblat. Teknik analisis yang dipakai penulis adalah teknik deskriptif analitik matematis, menggambarkan teori dan metode kulminasi Bulan secara matematis dan juga menggunakan analisis komparatif dengan membandingkan hasil perhitungan arah kiblat. Hasil temuan dari penelitian ini adalah akurasi metode kulminasi Bulan mendekati dengan metode modern (GPS dan Google Earth) dan dapat digunakan untuk keperluan perhitungan Arah kiblat. Hasil pengukuran titik koordinat menggunaan acuan kulminasi Bulan jika diimplementasikan dalam perhitungan azimut kiblat, jarak simpangnya memiliki nilai yang cukup rendah, sekitar 280,06 m hingga 7,87 km dari pengukuran GPS. Nilai ini masih sangat jauh dari batas toleransi arah kiblat sebesar 45 km. Dari pembuktian tersebut, titik koordinat menggunakan metode kulminasi Bulan dapat dijadikan acuan data yang cukup akurat dalam perhitungan arah kiblat
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
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
