Published: March 2019

Teripang Holothuria atra merupakan biota laut yang banyak ditemukan di perairan Indonesia yang termasuk dalam filum Echinodermata dan berpotensi sebagai antikanker. Penelitian ini bertujuan untuk mengetahui sitotoksisitas dan induksi apoptosis ekstrak etanol teripang H. atra secara in vitro terhadap beberapa sel lestari. Pengujian sitotoksisitas dilakukan dengan metode MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) menggunakan sel HeLa, T47D, WiDr dan sel normal Vero, sedangkan uji induksi apoptosis dilakukan terhadap sel dengan hasil uji sitotoksisitas terbaik menggunakan metode flowcytometry dan double staining. Hasil penelitian menunjukkan bahwa ekstrak etanol teripang H. atra mampu menghambat pertumbuhan sel kanker HeLa, T47D dan WiDr. Nilai IC50 ekstrak H. atra terhadap ketiga sel tersebut masing-masing sebesar 41,06±4,21; 20,89±1,55; 26,50±4,43 µg/ml tetapi esktrak tersebut memiliki sitotoksisitas yang lebih rendah terhadap sel Vero (IC50 sebesar 128,00). Analisis flowcytometry dan double staining pada sel T47D memperlihatkan bahwa ekstrak etanol teripang H.atra mampu menginduksi apoptosis pada sel tersebut.
Bienes comunes urbanos en tensión: el caso de la ecoaldea Velatropa, en Argentina/ Urban Commons in Tension: The Case of the Velatropa Ecovillage in Argentina
Authors: Fiore Giuliana 
Published: March 2019

El crecimiento de la Ciudad Autónoma de Buenos Aires (CABA) no escapa a la tendencia mundial de crecimiento poblacional en las zonas urbanas. En este contexto, surgen movimientos sociales que buscan construir alternativas a la forma de vida impuesta por la modernidad en las grandes urbes. Uno de esos movimientos se produce en torno a los procesos socioambientales de defensa y restauración de espacios verdes y de conformación de nuevas comunidades; movimientos que pueden pensarse en el marco de una resignificación y apropiación del territorio, para constituirlo en un bien común urbano. El objetivo del presente artículo es analizar las tensiones que produce la creación de nuevos bienes comunes urbanos a partir del análisis de caso de la ecoaldea Velatropa, ubicada en la Universidad de Buenos Aires, en CABA, Argentina. Para ello, se utiliza una metodología cualitativa, basada en el método etnográfico de observación participante, complementado mediante el análisis de fuentes secundarias. Los resultados describen la tensión fundamental que surge de las racionalidades contrapuestas por sobre las que actúa cada uno de los actores involucrados en el conflicto. En este caso, se encuentran cara a cara la convivencia comunitaria y ecológica del territorio con el uso mercantil del predio.

Abstract
The growth of the Autonomous City of Buenos Aires (CABA) does not escape the worldwide trend of population growth in urban areas. In this context, social movements emerge seeking to build alternatives to the way of life imposed by modernity in large cities. One of these movements takes place around the socio-environmental processes of defense and restoration of green spaces and the conformation of new communities. The movements can be thought in the framework of a resignification and appropriation of territory to constitute it in an urban common good. The objective of this article is to analyze the tensions produced by the creation of new urban commons based on the case analysis of the Velatropa ecovillage, located in the University Campus of the University of Buenos Aires, in CABA, Argentina. For this, the research uses a qualitative methodology, based on the ethnographic method of participant observation, complemented by the analysis of secondary sources of information. The results describe the fundamental tension that arises from the conflicting rationalities over which each one of the actors involved in the conflict acts. In this case, the community and ecological coexistence of the territory with the mercantile use of the property are face to face.

One of the principal's responsibility toward teacher is improving teachers' capability in managing teaching learning process in the school. Therefore, he must hold supervision perfectly. In fact, in many cases indicate that the principal, in general, who holds the duties of supervision in the school were not inherent with the principles of supervision yet. The methods used by the principal were less persuasive, whereas the appropriate method can determine the success supervision, because the activities of supervision are related with social interaction between supervisor and teachers. This article describes about individual's emotional intelligence that has influence in achieving the goals. Someone who has a high emotional intelligence is more success in his works, can develop a good personal relation, and motivate other people and himself The principal's emotional intelligence has influence toward achievement of his works significantly. The principal who has a high emotional intelligence is more success in holding supervision and duties, can develop a personal-interpersonal relations and motivate the teachers and himself well.
Signifikansi: Proses Pencarian Makna Terhadap Teks-teks Agama (Menyibak Pemikiran Nasr Hamid Abu Zaid)
Authors: Muzakki Akhmad 
Published: March 2019

Naturally, said Gadamer, word belongs to and is taken from reality. Human being looks for appropriate words as form of expression for reality. Ontologically, language created by human being is not only as a means of communication and thinking, but rather it is seen as the manifestation of reality, while they are articulating that language. Therefore, the meaning of a word is in the concept of thought. In the linguistic theory of Saussure, a word is a sign related to signifiant (which gives meaning) and signifie (which is given meaning). The signifiant gives form or expression while signifie concept or meaning. The relationship between the signifiant and the signifie based on the social convention is called signification, or "maghza" in Nasr Hamid's term. In other words, the signification is the effort of giving the meaning to the sign (language). Among the language philosophers, Jacques Derrida, for instance, the last signifie is not always admitted. Derrida said, meaning appears due to metaphor exchange and meaning changes when the speakers change. Or, as what Nasr Hamid had expressed, the meaning of the religious texts are not established when the text was made, but rather it is dynamic, relational, and changing depending on the socio-historical background of the readers.

ABSTRACT Reproductive design for gonadal maturation process mostly related with some factors such as environmental signals, reproductive organs, hormonal and nutrition. This research was conducted on female Mutiara strain of North African Catfish, Clarias gariepinus by combining two kinds of materials administered to broodstock diet, namely oocyte developer (Oodev) which contains of PMSG hormone and antidopamin, and astaxanthin carotenoid. Research designs were divided into C (Control), A50 (astaxanthin 50 mg/kg feed), A100 (astaxanthin 100 mg/kg feed), Od0.5 (Oodev 0.5 mL/kg fish for two weeks), Od1 (1 mL/kg fish for 2 weeks), Od0.5A50 (combined Od0.5 with A50), Od1A50 (combined Od1 with A50), Od0.5A100 (combined Od0.5 with A100), and Od1A100 (combined Od1 with A100). This research was performed during twelve weeks of feeding. The Od1A100 treatment showed the best reproduction performance result compared to other treatment with highest hepatosomatic (HSI) and gonadosomatic (HSI) indexes (P<0.05), also fastest increase in egg diameters (P<0.05), shorter rematuration periods and highest proportion of mature broodstock. These results indicated that Oodev and astaxanthin could accelerate gonadal maturity in female broodstock of Mutiara catfish.Keywords: Broodstock, hormonal, reproduction, oocyte developer, astaxanthin ABSTRAK Rekayasa reproduksi untuk proses pematangan gonad sebagian besar terkait dengan beberapa faktor seperti sinyal lingkungan, organ reproduksi, hormonal dan nutrisi.

Authors: Bonawitz Rachael , McGlasson Kathleen Lucy , Kaiser Jeanette L. , Ngoma Thandiwe , Lori Jody , Boyd Carol , Biemba Godfrey , Hamer Davidson H. , Scott Nancy A. 
Published: March 2019

Background: Maternity waiting homes (MWHs), defined as residential lodging near health facilities, are an intervention to improve access to maternal care recommended by the World Health Organization. Little is known about utilization of MWHs by HIV-positive women. This paper describes: 1) maternal awareness and utilization of MWHs in rural Zambia among HIV-positive women, and 2) health outcomes for HIVpositive women and their infants with regards to utilization of MWHs.
Methods: Data were collected from recently delivered women (delivered after 35 weeks in the previous 12 months) living >9.5 km from 40 health facilities in rural Zambia. For our analysis, primary outcomes were compared between self-identified HIV-positive and HIV-negative women in the sample. Primary outcomes include: 1) awareness of MWHs and 2) utilization of MWHs. We summarized simple descriptive statistics, stratified by maternal self-reported HIV status. We conducted bivariate analyses using chi-square tests, t-tests and Wilcoxon rank sum test.
Results: Among 2,381 women, 50 (2.4%) self-identified as HIV-positive. HIV-positive women were older and had more pregnancies and children than HIV-negative women (p<0.001). There was no difference in awareness of MWHs, but HIV-positive women were more likely to use a MWH than HIV-negative women. There was no difference in receipt of infant antiretroviral prophylaxis between women who did or did not stay at a MWH.
Conclusion and Global Health Implications: Though HIV prevalence in this sample was lower than expected, MWHs may represent a useful strategy to improve prevention of mother to child transmission of HIV in high prevalence, low-resource settings.
Key words: • Maternity waiting homes • HIV • PMTCT • Zambia

High performance adsorption of hazardous triphenylmethane dye-crystal violet onto calcinated waste mussel shells
Authors: Dandil Sahra , Sahbaz Deniz Akin , Acikgoz Caglayan 
Published: March 2019

AbstractSynthetic dyes are harmful to human beings, and the removal of colour from process or waste effluents is environmentally important. Crystal violet (CV) is a typical triphenylmethane dye, which is widely used in textile dyeing and paper printing industries. The present study shows that granulated and calcinated waste mussell shells (CWMS) can be used as a potential low-cost and locally available adsorbent for the removal of CV from aqueous solutions. The adsorption capacities of the CWMS for CV were investigated with respect to the effect of pH value, adsorbent dosage, contact time, initial dye concentration and temperature. Process variables were optimized, and a maximum dye adsorption of 482.0 mg/g was achieved at pH 6, 0.2 g/L adsorbent dosage, 220 min contact time and 25 °C for dye initial concentration of 100 mg/L. Adsorption kinetics and isotherms were followed by the pseudo-second order model and Freundlich isotherm models, respectively. Thermodynamic parameters demonstrated that adsorption of CV was spontaneous and endothermic in nature. The results indicated that the CWMS as a new adsorbent had the potential to serve in wastewater treatment applications, especially in the removal of CV from aqueous solutions.

Background: Several emerging problems of regular hemodialysis (HD) including cardiovascular complication or atherosclerosis formation caused by chronic inflammation. High sensitive C-reactive protein (hs-CRP) and intima-media thickness (IMT) of the carotid artery can be applied as atherosclerosis progressivity marker. This study was designed to investigate the relationship between some inflammatory factors, including hs-CRP, interleukin (IL)-6, oxidized-low-density lipoproteins (LDL), with IMT among end-stage renal disease (ESRD) patients. This was the first study in Indonesian population. Materials and Methods: This cross-sectional study was performed on ESRD patients who performed regular HD at Hemodialysis Unit of Dr. Kariadi Hospital and Telogorejo Hospital Semarang between October 2009 and April 2010. This was a preliminary report for the cohort study.Results: Seventy-eight HD subjects were enrolled in this study, with mean age of 49.8 years old. Mean HD duration was 25.5±32.16 months. The mean carotid artery wall thickness was 0.64±0.149 mm. IL-6, hs-CRP, and ox-LDL level were higher in IMT group ≥0.5 mm than IMT group <0.5 mm. There was a significant correlation between hs-CRP (prevalence ratio (PR)=1.3; 95% confidence interval (CI)=1.02-1.7; p-value=0.01) as well as IL-6 (PR=1.5; 95% CI=1.1 -2.0; p-value<0.001) and IMT wall thickness. The oxidized-LDL level was not a significant factor to be associated with IMT. The cut-off value for hs-CRP and IL-6 to predict IMT progressivity was 2.8 mg/L and 2.88 mg/L, respectively.Conclusion: There was a significant correlation between IL-6 and hs-CRP levels and IMT. There was not significant correlation between oxidized LDL and IMT.Keywords: hemodialysis, atherosclerosis, IMT, IL-6, hs-CRP, Oxidized-LDL
