Full text linkKaempferia rotunda, usually called as temu putih is belonging into Zingiberaceae family.This plant has been used as traditional medicine for curing diarrhoe and disentry.Objective of the study was to determine the effect of pseudo tubers number and organicfertilizers on the productivity of K. rotunda. Research was conducted in TreubLaboratory, Research Centre for Biology LIPI, Bogor, from July 2002 until April 2003.The experiment was arranged in a factorial Randomized Block Design. The treatmentsconsisted of two factors, i.e the first factor were number of pseudo tubers (0, 2 and 4)and second factor were organic fertilizers (soil, goat manure and compost).The result of the exsperiment showed that both factors, i.e number of pseudo tubers andorganik fertilizers significantly affect productivity of K.rotunda. The effect of goatmanure more dominant than compost. The interaction of those two factors significantlyinfluenced number of leaves and fresh weight of rhizome. The best results was on thecombination treatment of two pseudo tubers and goat manure which had the highestvalue on all peubahs observed which were increased growth and yield of K. rotundasignificantly
Respon Pertumbuhan Bibit Picrasma javanica Blume terhadap Intensitas Naungan dan Media Tanam
Full text linkStudy on the growth response of Picrasma javanica Blume seedling to different shading intensities and medium was conducted at the Experimental Garden of Treub Laboratory, Research Centre for Biology, LIPI from June to December 2007. The research was arranged using Factorial in Completely Randomized Block Design with 2 factors and 5 replications. The first factor was shading intensities which were 0% (N0, without shading, average light intensities 39300 lux), 25% (N1, average light intensities 16430 lux), and 50% (N2, average light intensities 5867 lux), respectively and the second factor was medium (combinations of soil: manure:compost) with 6 levels were M1= 1:0:0, M2= 1:1:1, M3= 1:1:2, M4= 3:1:1, M5= 1:2:1, and M6= 2:1:1. The result showed that the N0 treatment (without shading) resulted the best growth response of Picrasma javanica Blume seedling, as showe in all parameters observed (plant height 27.11 cm; leaf number 15.57; diameter of trunk 4.32 mm; and root length of 15.97 cm, shoot dry weight of 1.762 g, root dry weight of 0.688 g and seedling quality index of 0.277). The growth media treatment of M5 (1-soil:2 manure:1 compost) showed the positive response on the growth of seedling better than other treatments and different with control (M1, soil media), with parameters were observed which was plant height 25.05 cm (M1= 19.10 cm); leaf number 16.53 (M1= 9.20); diameter of trunk 3.89 mm (M1= 2.76 mm); root lengh 15.23 cm (M1= 12.71 cm); shoot dry weight 1.58 g (M1= 0.663 g); root dry weight 0.51 g (M1= 0.221 g) and seedling quality index 0.220 (M1= 0.089). The combination treatment of N0 (without shading) and media M5 (1:2:1) gave the best response on the growth of Picrasma seedling (plant height 36.14 cm; leaf number 28.2; diameter of trunk 4.7 mm; and root length 16.7 cm, shoot dry weight 3 g and root dry weight 0.92 g)
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
PENINGKATAN PRODUKSI DAN PERBAIKAN UKURAN UMBI KENTANG HITAM (Plectranthus rotundifolius (Poir.) Spreng) MELALUI TEKNIK BUDIDAYA SEBAGAI UPAYA KONSERVASI
Full text linkA decrease of the role of a species in the society culture can lead to scarcity and even the extinction of that species. Along with the government program to diversify food, it can be repopularized the underutilized carbohydrate source potential plants with the aim as the plant conservation efforts. Related to this, the hausa potato (Plectranthus rotundifolius) can be an alternative food source for the people who occupy arid areas. Hausa potatoes not only serve as a carbohydrate source with low glycemic index, but also rich in essential vitamins and minerals. Information on cultivation techniques become important things that need to be prepared within the framework of development. The study was conducted to answer questions regarding cultivation techniques that need to be done to improve the quality of the hausa potato crop in the market. The study was designed based on a randomized block design (RCBD) two factors, four hausa potato accessions and four types of cultivation techniques (four hausa potato accessions: Nganjuk, Sangian, clone 6G and O3; and four types of cultivation techniques: stockpilling, prunning, mulce, and lifting). Every treatment consist of four replications with three plants/replications. Observations were made on growth and yield parameters. The results showed that the different hausa potatoes accession need different cultivation techniques to improve the yield and tuber size. The use of rice straw mulch on hausa potato cultivation can improve the size of hausa potato tubers in the rainy season
Respon Pemberian Hormon Tumbuh Dan Mikoriza Terhadap Pertumbuhan Stek Ramin (Gonystylus Bancanus (Miq.) Kurz)
Full text linkThis study was conducted to determine the effect of growth hormones and mycorhyza application on the growth of ramin cuttings. A Completely Randomized Design with 5 replicates was used in this study. The experiment consisted of two stages i.e hormon treatments (control, Rapid root, Root Up, IBA 250 mg/l, IBA 500 mg/l, IBA 1000 mg/l), Fusarium and mycorhyza applications. The result showed that the highest number of root was obtained from Root Up (12,83 cm), while the lowest was from Fusarium treatments (4,67 cm). IBA 250 mg/l enhanced the number of roots and the length of root significantly but not stimulate the development of new leaf. While mycorhyza application improving the growth of the new leaf and the root development of ramin
