Integrasi Nilai Karakter pada pembelajaran sejarah lokal
Full text linkIntegrasi pendidikan karakter dalam kurikulum pendidikan Indonesia, mulai dari lembaga pendidikan dasar hingga perguruan tinggi belum nampak hingga saat ini. Peguruan Tinggi sebagai gerbang akhir sebelum peserta didik kembali ke tengah masyarakat mengaplikasikan ilmunya, dianggap belum punya bekal yang cukup untuk menelorkan nilai-nilai yang baik bagi masyarakat. Integrasi pendidikan karakter dalam berbagai mata kuliah, khususnya Mata Kuliah Sejarah Lokal yang memiliki materi yang memiliki korelasi dengan pendidikan karakter karena mengandung local wisdom, local genius atau local knowledge diharapakan menjadi komando dalam pengintegrasian pendidikan karakter pada mata kuliah lainnya. Khusus di Sejarah Lokal Sulawesi Selatan yang memiliki beragam nilai karakter yang terkandung dalam lontara, lontara bilang, pappaseng dan sumber-sumber sejarah lokal lainnya adalah kekayaan yang tidak ternilai yang dapat menjadi sumber sejarah yang berbasis pendidikan karakter
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
Pembuatan Papan Gipsum Plafon dengan Bahan Pengisi Serbuk Batang Kelapa Sawit dan Bahan Perekat Polivinil Alkohol
No full textThe purpose of this research is to produce a gypsum board ceiling using filler palm oil stem powder and polyvinyl alcohol adhesive. The gypsum board ceiling is produced by varying gypsum and a palm oil stem powder in which later mixed with polyvinyl alcohol adhesive. In this research, Gypsum Jayaboard is used as the standard of comparison. The mechanical characteristic is based on SNI 03-2105-2006 and SNI 07-6732-2001 which is the testing of standard procedure. The most optimum variations obtained by the mechanical testing of 25 g gypsum, 25 g of palm oil stem powder, and 15 g polivynil alcohol adhesive resulting 4,07 MPa of flexural strength value, 24,07 MPa of modulus of elasticity, 1,52 MPa of tensile strength, and 5000 J/m2 of impact. But the results do not meet specifications of SNI-6384-2000, it’s about spesifications of gypsum board to the test results for flexural strength and modulus of elasticity. For the results of physical properties characteristics obtained density are 1,29 g/cm3, 46,93% of water absorbtion, 135°C of glass transition temperature, 445oC of decomposition point, and showed that mixed physical bonding.Penelitian mengenai pembuatan papan gipsum plafon dengan bahan pengisi serbuk batang kelapa sawit dan bahan perekat polivinil alkohol selesai dilakukan. Papan gipsum plafon dibuat dengan memvariasikan antara gipsum dengan serbuk batang kelapa sawit yang kemudian dicampurkan bersama perekat polivinil alkohol. Dalam penelitian ini, gipsum merk Jayaboard digunakan sebagai pembanding. Karakterisasi mekanik mengacu pada SNI 03-2105-2006 dan SNI 07-6732-2002 yang merupakan prosedur standar dari pengujian. Variasi yang paling optimum dari pengujian mekanik diperoleh untuk gipsum 25 g, serbuk batang kelapa sawit 25 g, dan perekat polivinil alkohol 15 g dihasilkan nilai kuat lentur 4,07 MPa, modulus elastisitas 24,07 MPa, kuat tarik 1,52 MPa, dan impak 5000 J/m2. Akan tetapi hasil ini belum memenuhi SNI 03-6384-2000 tentang spesifikasi papan gipsum untuk hasil pengujian kuat lentur dan modulus elastisitas. Hasil karakterisasi sifat fisik diperoleh densitas 1,29 g/cm³, penyerapan air 46,93%, yang memenuhi SNI-01-4449-2006. Hasil karakterisasi sifat panas menghasilkan suhu transisi gelas sebesar 135oC, titik dekomposisi sebesar 445oC, dan menunjukkan bahwa campuran hanya terjadi pada ikatan secara fisis saja.91 HalamanTesis Magiste

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

No full textConcrete bricks in this study is made of a mixture of cement, sand, fly ash, pumice
and ash from rice husk. Variables on this brick is the composition of fly ash
substituted for cement ranging from 0 – 30 % of the volume of adhesive and a
substituted pumice sand + rice husk ash ranging from 0 – 55 % of the aggregate
volume, where the ratio between the volume of pumice with rice husk ash is 1 : 1
and a comparison between the adhesive and the aggregate volume is 1 : 4. The
brick characteristest have been perfomed including density, water absorption,
compressive strength, fracture strength, impact strength, and obtained the results
for density (1649.41 to 1865.08 kg / m³), water absorption (9.60 to 19.23 %) ,
compressive strength (4.74 to 8.73 MPa), fracture strength (0.27 to 1.31 MPa)
and impact strength (from 6666.67 to 10444.44 J/m²). Test results indicate and
increasing ash percentage characteristics of fly ash as substitute of cement and
pumice and rice husk ash as substitute for sand resited in a decreased density,
compressive strength, fracture and impact strength, but increased for absorption
of water. Based on test data characteristics of a brick and concrete brick walls for
the pair in accordance with SNI as a comparison, we conclude that fly ash can
be used as substitute for cement and pumice and ash from rice husk can be used
as substitute for sandBatako dalam penelitian ini dibuat dari campuran semen, pasir, abu batubara, batu
