ANALISIS PERBEDAAN TRADING FREQUENCY ANTARA PORTOFOLIO OPTIMAL DENGAN PORTOFOLIO TIDAK OPTIMAL DI BURSA EFEK JAKARTA (Studi Empiris Model Indeks Tunggal Pada Perusahaan Manufaktur)
Seorang investor dalam melakukan investasi di pasar modal memerlukan
pengetahuan yang cukup, pengalaman, serta naluri bisnis untuk menganalisa efek-
efek mana yang akan dibeli, mana yang akan dijual dan mana yang akan tetap
dimiliki. Salah satu strategi investor untuk meminimalkan resiko investasi pada
saham adalah dengan melakukan diversifikasi saham dalam suatu portofolio.
Tujuan penelitian ini adalah untuk mengetahui apakah terdapat perbedaaan
trading frequency yang signifikan antara portofolio optimal dengan portofolio
tidak optimal di Bursa Efek Jakarta. Dalam melakukan analisis tersebut
menggunakan Model Indeks Tunggal.
Penelitian ini menggunakan data harga saham penutupan (closing price)
bulanan, saham-saham perusahaan manufaktur dari bulan Januari 2002 sampai
dengan bulan Juni 2004 sebagai populasi, dan metode pengambilan sampel
dengan purposive sampling, yaitu dengan hanya memilih saham-saham
perusahaan yang mempunyai rata-rata return saham positif, dari hasil perhitungan
tersebut terdapat 55 perusahaan yang dijadikan sebagai sampel penelitian.
Hasil penelitian menunjukkan adanya perbedaan yang signifikan dari
trading frequency antara portofolio optimal dengan portofolio tidak optimal di
BEJ yang tercermin dari hasil pengujian hipotesis dengan menggunakan Mann-
Whitney menunjukkan bahwa Asymp. Sig. (2-tailed) adalah sebesar 0,049 atau
probabilitas < 0,05 (0,049 < 0,05)

PENERAPAN STRATEGI PEMBELAJARAN INKUIRI SEBAGAI UPAYA MENINGKATKAN KEAKTIFAN DAN HASIL BELAJAR TEORI DASAR-DASAR PENGELASAN KELAS XII DI SMK KRISTEN 1 KLATEN TAHUN AJARAN 2013/2014
The purpose of this research was to know the learning process and underlying principles of welding achievement students of with problem based learning. This research is Classroom Action Research. The subjects in this research were students of class XII which is 21 students. The data collecting technique in this research was done by using observation, and tests. The result of this research showed an increase in the learning process and achievement of students in the learning process. This is indicated by an increase in percentage of students learning process on the first cycle is 74%, while on the second cycle increased to 79%, and while on the third cycle increased to 85%. The percentage of the KKM students also increased, first cycle at 28,57% increased to 33,33% in the second cycle, and the third cycle again increased to 76,19%
PENGEMBANGAN TEKNOLOGI TUNGKU PEMBAKARAN DENGAN AIR HEATER TANPA SIRIP
Tujuan penelitian ini untuk mengetahui pengaruh penggunaan air heater tanpa sirip pada tungku pembakaran terhadap temperatur tungku pembakaran, temperatur gas cerobong, waktu pendidihan air dan mengetahui nilai efisiensi tungku pembakaran dengan bahan bakar sekam padi.
Metode penelitian yang digunakan berupa pengujian pengaruh temperatur tungku pembakaran, temperatur gas cerobong, temperatur gas air heater, lama waktu pendidihan air, serta mengetahui nilai efisiensi thermal tungku berbahan bakar sekam padi dengan penambahan air heater tanpa sirip sebagai laluan udara dalam proses pembakaran dengan variasi kecepatan udara 9,5 m/s, 10,5 m/s, 11,5 m,s.
Hasil penelitian menunjukkan bahwa variasi kecepatan udara pada air heater sangat berpengaruh pada temperatur tungku pembakaran, temperatur gas cerobong, waktu pendidihan air dan efisiensi tungku. Dimana temperatur tungku tertinggi didapat pada kecepatan udara 9,5 m/s dengan temperatur 636°C, temperatur gas cerobong tertingii 427° pada kecepatan udara 11,5 m/s, waktu pendidihan air tercepat pada kecepatan udara 9,5 m/s dengan waktu total 100menit dan nilai efisien tungku pembakaran terbaik adalah 64,65% pada percobaan tungku pembakaran dengan penambahan air heater tanpa sirip dengan kecepatan udara 9,5 m/s
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
