TUMBUHAN AIR LAHAN BASAH SEBAGAI AGEN FITOREMEDIASI DAN KEMAMPUANNYA MENURUNAN POLUSI LIMBAH CAIR
No full textABSTRAK
Limbah cair merupakan kombinasi cairan dan partikal padat tersuspensi yang
dibuang ke lingkungan dari berbagai fasilitas seperti pemukiman, perdagangan,
perkantoran, rumah makan, industri, rumah sakit yang biasanya mengandung bahanbahan
yang dapat membahayakan kehidupan manusia, serta menggangu kelestarian
lingkungan hidup. Pengolahan limbah cair dari berbagai sumber secara alami dapat
terjadi pada wilayah lahana basah yang banyak terdapat tumbuhan air, proses
pengolahan limbah dengan menggunakan tumbuhan air ini disebut fitoremediasi.
Penelitian dilakukan dengan menggunakan 4 jenis tumbuhan air dan 3 jenis kombinasi
tumbuhan dengan menggunakan media yaitu aluvial dan zeolit. Pengamatan dilakukan
secara periodik 10, 20, dan 30 hari terhadap bahan pencemar. Kombinasi perlakuan
media penyaring tanah aluvialzeolit
dengan tumbuhan air wlingenkiapu
merupakan
kombinasi perlakuan yang terbaik mengurangi kadar bahan pencemar,dengan nilai
keefektivan berkisar antara 7298.82%

An Integrated Decision Support System (DSS) for the Management of Sustainable Mariculture in Indonesia
Get PDFIndonesia has great potential for aquaculture development but its expansion is often insufficiently focused in environmentally sustainable practice. For this reason, regarding an ecosystem approach to aquaculture (EAA),the aim of this paper is to demonstrate the application of decision support system for the management of sustainable floating net cage mariculture (SYSMAR DSS)in three selected regions in Indonesia: Talise Island, Galang Island and Ekas Bay.Through GIS spatial planning tools, SYSMAR DSS is used to perform site selection and assesses production and ecological carrying capacity. Economic analysis provides vital information on 18 cases, focusing on the economic viability of Tiger Grouper (Epinephelus fuscoguttatus), Humpback Grouper (Cromoliptes altivelis)and Leopard Coral Grouper (Plectropomeus leopardus) which utilizes various feed types and production scales.SYSMAR DSS shows that only Galang Island provides a substantialarea with a suited area of about 12,940 ha. The estimated maximum production carrying capacity is 51 – 366 tons/farm andecological carrying capacity is in the range 18,393 – 21,727 tons/year/suitable area. After a 5-year projection period, the economic evaluation highlighted that all studied culture developments are economically viable. These results confirm the SYSMAR DSS is able to determine potential sites which comply with environmental sustainability and socio-economic criteria

PIMPINAN YANG MELAYANI TERHADAP BURNOUT TENAGA KESEHATAN: MEDIASI KEAMANAN PSIKOLOGIS
No full textThis research was carried out on health professional at Budhi Mulia Mother and Child Hospital Pekanbaru with the aim of examining the role of psychological security in mediating the influence of serving leaders on burnout. The population and sample of the study were health professional of Budhi Mulia Mother and clild Hospital Pekanbaru, totaling 98 people. Analysis of the research data using descriptive statistics and verification analysis, as an analytical tool used Structural Equational Model which is processed with SmartPLS2 Software. The results of the analysis prove that at Budhi Mulia Mother and Child Hospital Pekanbaru, the more effective the serving leader, the more likely it is to reduce burnout; the behavior of leaders who serve improve the psychological security of employees; a high level of psychological security in the health professional of RSIA Budhi Mulia, reducing work fatigue; and serving leaders have an effect on burnout of health professional through psychological security mediation
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
