ABSTRAK
Malaria merupakan salah satu penyakit di dunia termasuk Indonesia yang
disebabkan oleh Plasmodium. Kasus malaria diperparah dengan timbulnya
resistensi Plasmodium karena penurunan akumulasi obat pada pencernaan parasit,
mutasi gen dan tingginya resistensi penggunaan antimalaria. Penemuan
antimalaria baru terus diupayakan termasuk dari tumbuhan. Coptosapelta
tomentosa adalah tumbuhan obat Indonesia yang digunakan secara empiris oleh
masyarakat Kotabaru dalam pengobatan malaria. Penelitian ini bertujuan
menentukan persentase penghambatan dan nilai IC50 polimerisasi hem setelah
pemberian infusa akar C. tomentosa. Penelitian ini dilakukan dengan pemberian
sampel uji pada konsentrasi infusa 17; 8,5; 4,25; 2,125; 1,0625 dan
0,53125 mg/mL. Hasil penelitian rata-rata kadar hemozoin pada konsentrasi
sampel infusa masing-masing sebesar 54,67±8,76; 85,82±3,20; 97,24±7,44;
100±0; 100±0 dan 100±0 mg/mL. Rata-rata persen penghambatan pada
konsentrasi infusa secara berturut-turut adalah 63,13±5,91; 42,12±2,16;
34,42±5,02; 24,69±8,34; 13,79±5,20 dan 0±0. Nilai IC50 penghambatan
polimerisasi hem infusa akar C. tomentosa adalah 9,61±0,99 mg/mL. Analisis
data menggunakkan uji Independent Sample t-Test membandingkan antara IC50
infusa terhadap klorokuin difosfat didapatkan hasil p > 0,05 yang menunjukkan
tidak terdapat perbedaan yang bermakna, artinya infusa akar C. tomentosa
memiliki aktivitas penghambatan polimerisasi hem yang sebanding terhadap
klorokuin difosfat.
Kata Kunci : Coptosapelta tomentosa Valeton ex K. Heyne, IC50, Infusa,
penghambatan, polimerisasi hem.

Abstrak
Cawat hanoman (Labisia pumila) salah satu tanaman yang digunakan secara empirik sebagai afrodisiaka di Kalimantan Selatan. Penggunaan secara tradisional dengan meminum air rebusan akar cawat hanoman. Penelitian bertujuan mengetahui dosis dan persentasi fraksi n-butanol akar cawat hanoman yang memberikan efek afrodisiaka mencit putih jantan. Penelitian dilakukan dengan cara non hormonal berdasarkan parameter introduksi, klimbing, dan koitus. Mencit dikelompokkan dalam 5 kelompok, kontrol negatif (KN), kontrol positif mestrolon (KP), dosis 2 mg/kgBB (K1), dosis 5mg/kgBB (K2), dosis 10mg/kgBB (K3). Mencit jantan diadaptasi 5 menit setelah pemberian fraksi n-butanol, selanjutnya dikumpulkan dengan 3 ekor mencit betina estrus dalam satu kandang. Jumlah introduksi, klimbing, koitus dihitung dan dianalisis pada tingkat kepercayaan 95%. Hasil analisis diperoleh perbedaan bermakna antara perlakuan dan terhadap kontrol. Aktivitas afrodisiaka pada mencit putih jantan dosis 5 mg/kgBB (K2) memberikan efek paling baik yakni introduksi 80,15%, klimbing 99,35%, koitus 100% terhadap kontrol negatif dan memberikan efek introduksi -6,34%, klimbing 69,03%, dan koitus 91,30% terhadap kontrol positif. Fraksi n-butanol mengandung senyawa golongan alkaloid, saponin dan steroid.

The Effectiveness of Problems Plane Game as a Joyful Learning Strategy in Developing Students’ Speaking Skills of SMAN 16 Makassar
Full text linkArnida. 2017. The Effectiveness of Problems Plane Game as a Joyful Learning Strategy in Developing Students’ Speaking Skills of SMAN 16 Makassar. Thesis. Faculty English and Literature. English Department. Supervised by Prof Baso Jabu and Amra Ariyani.
This thesis presents the description of the students’ speaking skills and interest toward the use of discussion by using Problems Plane Game in the classroom. It aims at finding the answers to the following problems: 1) Is the use of problems plane game effective to enhance the speaking skills of the second year students of SMAN 16 Makassar? And 2) Does the use of Problems Plane game attract the student’s interest to enhance their speaking skills? In this research the writer applied the pre-experimental method by using Pretest, Posttest and treatment. The writer collected data by using two instruments; the first is interview to obtain data about the students’ speaking skills consists of accuracy, fluency and comprehensibility. The second is questionnaire to obtain data about the students’ interest. The research findings show that the students’ accuracy there are 10 (45.5%) students categorized as good and 12 (54.5%) as very good. the student’s fluency show that 12 (54.5%) students categorized as very good and 10 (45.5%) students categorized as good. and the student’s comprehensibility show that there are 11 (50 %) students categorized as very good, 9 (40.9%) students categorized as good and 2 (9.1%) students categorized fair. The questionnaire shows their interest in speaking English in the classroom through Problem Plane Game with percentages there are 9 (40.9%) students categorized as very high interest and 13 (51.9%) students as high interest. None of them belongs to moderate, low and very low interest
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
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
