PERKAWINAN DI BAWAH UMUR DAN IMPLIKASINYA TERHADAP KEHARMONISAN RUMAH TANGGA (Studi Kasus di KUA Kecamatan Parengan Kabupaten Tuban)
Full text linkFenomena pernikahan dibawah umur ini memang bukan suatu hal yang baru, akan tetapi yang perlu diperhatikan seperti ini adalah apakah pernikahan di bawah umur ini akan bisa berjalan dengan harmonis atau tidak, karena pernikahan merupakan suatu hubungan yang harus mempunyai kecakapan lahir dan batin, baik dari skis maupun psikologis. Dalam Undang-undang No.16 Tahun 2019 tentang perkawinan pasal 7 ayat 1 disebutkan bahwa setiap warga negara untuk melakukan perkawinan hanya diizinkan jika pihak pria dan Wanita sudah mencapai usia 19 tahun. Namun pada kenyataannya hal tersebut tidak berlaku untuk sebagian masyarakat Kecamatan Parengan Kabupaten Tuban. Hal ini yang menyebabkan penyusun merasa perlu untuk mengkaji apa saja sebab-sebab masyarakat Kecamatan Parengan melakukan pernikahan di bawah umur dan bagaimana implikasinya dengan keharmonisan rumah tangga sehingga diketahui seberapa banyak keluarga yang harmonis atau tidak harmonis dari pernikahan tersebut. Dalam penelitian ini metode yang digunakan adalah penelitian lapangan (field research) dan bersifat deskriptif. Pengumpulan data dengan observasi secara langsung dan wawancara dengan responden terhadap pasangan pernikahan dibawah umur serta keluarga atau kerabat. Data yang diperoleh penyusun dalam penelitian ini bersumber dari Kantor Urusan Agama Kecamatan Parengan Kabupaten Tuban, khususnya perkara pernikahan di usia muda,yang terjadi tahun 2016 sampai 2020. Hasil penelitian ini menyimpulkan bahwa sebagian masyarakat Kecamatan Parengan Kabupaten Tuban menikah di usia muda disebabkan karena adanya empat hal yaitu faktor ekonomi, pergaulan bebas, pendidikan, dan perjodohan. Dari faktor tersebut yang paling banyak adalah karena pergaulan bebas. Sejauh ini keluarga pasangan pernikahan d bawah umur di Kecamatan Parengan Kabupaten Tuban dikategorikan sebagai keluarga yang harmonis
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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
Full text linkWe 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
PEMILIHAN MONOMER FUNGSIONAL PADA MOLECULARLY IMPRINTED POLYMER (MIP) DIAZEPAM DENGAN TEKNIK KOMPUTASI
No full textTeknik preparasi yang tepat dapat mempengaruhi hasil analisis sehingga pemilihan preparasi sampel yang tepat harus diperhitungkan terutama untuk analisis diazepam dalam matriks sampel yang rumit seperti serum dan urin. Molecularly imprinted polymers (MIP) merupakan salah satu teknik preparasi yang efektif untuk mengekstrak analit target dari matriks kompleks sebelum analisis. Pemilihan monomer fungsional merupakan hal terpenting dalam pembuatan MIP yang baik, sehingga pemilihannya sesuai dengan sifat fisikokimia monomer dan diazepam sebagai tamplate. Interaksi monomer dan tamplate yang memberikan nilai binding affinity yang paling baik pada monomer asam adalah p-vinylbenzoic acid sebesar -3,3 kkal/mol, pada monomer basa adalah 5-[1-(2,3-dimethylphenyl)ethenyl]-1H-imidazole sebesar -3,8 kkal/mol dan pada monomer netral adalah ethylstyrene sebesar -3,6 kkal/mol. Dari semua monomer yang diuji baik monomer asam,basa atau netral yang menghasilkan binding affinity yang baik adalah monomer basa yaitu 5-[1-(2,3-dimethylphenyl)ethenyl]-1H-imidazole sebesar -3,8 kkal/mol yang artinya template diazepam akan berinteraksi dengan baik dengan monomer tersebut.

An Update on the Use of Molecularly Imprinted Polymers in Beta-Blocker Drug Analysis as a Selective Separation Method in Biological and Environmental Analysis
No full textBeta-blockers are antihypertensive drugs and can be abused by athletes in some sport competitions; it is therefore necessary to monitor beta-blocker levels in biological samples. In addition, beta-blocker levels in environmental samples need to be monitored to determine whether there are contaminants from the activities of the pharmaceutical industry. Several extraction methods have been developed to separate beta-blocker drugs in a sample, one of which is molecularly imprinted polymer solid-phase extraction (MIP-SPE). MIPs have some advantages, including good selectivity, high affinity, ease of synthesis, and low cost. This review provides an overview of the polymerization methods for synthesizing MIPs of beta-blocker groups. The methods that are still widely used to synthesize MIPs for beta-blockers are the bulk polymerization method and the precipitation polymerization method. MIPs for beta-blockers still need further development, especially since many types of beta-blockers have not been used as templates in the MIP synthesis process and modification of the MIP sorbent is required, to obtain high throughput analysis
Synthesis of Mesoporous Silica Imprinted Salbutamol with Two TEOS/MTES Ratio Compositions through the Direct Incorporation Method for Salbutamol Separation
No full textMolecularly imprinted mesoporous silica (MIPMS) is one of the methods to improve site accessibility molecule target on molecularly imprinted polymer (MIP) for application in solid-phase extraction (SPE). The MIPMS was prepared using salbutamol sulfate as template molecule, cetyltrimethylammonium bromide as a directing agent, and tetraethyl orthosilicate and methyltriethoxysilane were used as silica precursor and organosilane. In this study, two TEOS : MTES ratios were used. The MIPMS-2 with 3 : 1 ratio of TEOS : MTES has better analytical performance than the MIPMS-1 with 2 : 1 ratio of TEOS : MTES. The adsorption capacity of MIPMS-2 was about 0.0934 mg/g, and it was 0.0407 mg/g for NIPMS-2. The extraction ability of MIPMS-2 was good, with a recovery of about 104.79% ± 1.01% of salbutamol in spiked serum. The imprinting factor (IF) value obtained is 1.2. When serum was spiked with salbutamol and terbutaline, the ability of NIPMS-2 to recognize salbutamol increased. Therefore, optimizing the conditions for the MIPMS synthesis is necessary to produce a sorbent with better selectivity
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
