Published: December 2018

Technology to process food waste should be easy maintenance, fast, economical, affordable, environmentally friendly, and socially acceptable. Processing food waste according to the principle is biological decomposition. Biological processes usually take quite a long time (30 days). This study aims to accelerate the process of decomposition of food waste and produce a quality fertilizer products. Bulking agent (biofilm), bio activator (microorganism from cassava), and bio-drying technology are used to accelerate the decomposition process. The ratio of food waste and bulking agent is 7:3 (v/v). Mature product serves as a bulking agent and additive microorganisms. Additive microorganisms are also done by adding microorganism derived from cassava with a ratio of 10ml/500 g (Ml); 20 ml/500 g (M2); and 10ml/500 g of food waste (M3). The results showed the temperature of the food waste reached 50 ? at first. The addition of bulking agent and Additive microorganisms causes the thermophilic phase to occur early. This shows the thermophilic phase being achieved in a short period. Based on testing of compost maturity parameters, food waste has matured within 3 days. The C-Organic Concentration was 27.57%, N-total 1.98%, C/N ratio of 13.92, P-Total 0.23% and K-total 0.83%. In conclusion of this study, mature compost can be used as bulking agent with mature compost ratio and 7: 3 (v/v) bulking agent. Processing food waste is quite effective using a combination of bulking agent (mature compost), additive microorganisms and bio-drying technology.

Authors: Hernayanti  , Slamet Santoso , Sri Lestari
Published: December 2018

Cadmium is one of a heavy metal which widely used in human life, especially in the electroplating industry and a mixture of textile materials. Cadmium that enters the body binds to the metallothioneins protein. It can increase the formation of free radical compounds, there by inhibiting enzyme activity such as nitric oxide synthase3. This gene regulates the expression of endothelial nitric oxide synthase which produce a nitric oxide. Nitric oxide role in regulated blood pressure as vasodilator with Angiotensin II as vasoconstriction. The susceptibility to Cd exposure will elevate if the polymorphisms of gene is found in population. The aim of this research was to know effect of cadmium to gene NOS3 polymorphisms on NO, systolic and diastolic blood pressure and antioxidant enzyme in Cd-exposed individual. The genotype individual were detected by Polymerase Chain Reaction-Restriction Fragment Length Polymorphisms (PCR-RLFP) with MBo1 restriction enzyme. Parameter recorded were blood Cd , NO level, SOD, systolic and diastolic. Data were analyzed by independent t-test. These result showed that 20% of 40 individual of cases subject were detected as polymorphisms individual of NOS3gene, with GA genotype. Their fragment DNA located on 206 bp, 119 bp and 87 bp, but non polymorphisms of NO gene is only located on 206 bp. The result show cadmium could influence polymorphisms NOS3gene and decrease NO production followed by increasing of blood pressure both systolic and diastolic. Cadmium also decrease antioxidant enzyme SOD and GPx level.

Published: December 2018

Mangrove forests in Indonesia play an important role in mitigating climate changes and providing other ecosystem services; however, their extent continues to decline. Information on mangrove community and its carbon stock, especially for Papua, is still limited. This study was conducted to describe vegetation structure and estimate carbon stock in Payumb Coast in Merauke District, Papua. There were three primary mangrove species identified, namely, Avicennia alba, Rhizophora apiculata and Sonneratia alba. Species dominance varied along a gradient of salinity and substrate perpendicular to the shoreline. A. alba is dominant in the closest zone to the shoreline (importance value 205.76%), while R. apiculata is dominant in the farthest zone (importance value 185,35). At the community level, the carbon stock in trees differed significantly between zones (p<0.05), with the highest in the zone dominated by R. apiculata. This study has provided preliminary data on carbon stock estimation at the community level; further studies should be conducted to estimate total carbon stock based on all above- and belowground components. More accurate estimations become important, as it was found that different species could contain significantly different carbon stock; thus producing variation among mangrove communities.

Democratization in developing countries triggered by globalization has led decentralization. Post New-Order Indonesia chose decentralization as its policy to improve democratization, allowing transfer of authority to its local governments, thus raises roles taken by sub-state actors, including in international relations. States, regions, provinces and cities seek their way to promote trade, investments, cooperation, and in some cases, political support, through cross-borders contacts with their international counterparts. The phenomenon which later understood as “paradiplomacy” is thus defined as communication conducted by sub-state actors aimed to promote identity and or pursuing local interests. This study analyze how Semarang, as a melting pot city in Java, positioned itself in international community and develop its own paradiplomacy. The study finds that Municipal Government of Semarang with authority expanded by decentralization uses paradiplomacy as a mean to achieve economic interest, especially to expand market and attract foreign investment, with its environmental issue that remains left-behind. The prototype of paradiplomacy is found in “SemBiz”, annual expo in trade and investment held by Municipal Government of Semarang. Not only serves economic development in Semarang, paradiplomacy is also utilized to preserve, if not strengthen, its locality as integral part of Semarang's identity.

Democracy and Continuing Marginalization of Women in Indonesian Politics
Authors: Hara Abubakar Eby , Trihartono Agus , Viartasiwi Nino
Published: December 2018

Although much progress and efforts have been made to increase women’s participation in politics, the main idea of women’s involvement in politics has not yet penetrated into the mainstream of Indonesian politics. The main idea is not only a representation of the number of female population but also the representation that will bring new norms for Indonesian politics that has been so far dominated by the assumption of masculinity based on power politics and struggle to control resources by one party for the loss of others. This paper seeks to see how this marginalization of women continues to occur. One of the reasons for this cannot be separated from the waning of the reform spirit that inspired the reformation. Slowly but surely Indonesian politics is re-defined in term of power struggles by all means including by corruption, collusion, and nepotism that was once the object of criticism of reform groups. In this context, it is often the case that if women want to succeed in politics, they must follow such political norms and abandons the idealism of their struggle. In fact, such women politicians not only abandon the ideal of feminist struggle but reinforce the assumption that politics is the world of men.

Published: December 2018

We have investigated the effect of sudden water condensation processes and the behavior of its condensed water prior evaporation, with an integrated resonant photonic structure and dynamic tracking of its transduced signal. The aim of this analysis is to develop a water condensation lab-on-chip sensor, with the possibility of data treatment with an embedded system. Integrated photonic micro-resonator (MR) devices have been designed and fabricated with polymer UV210 by means of Deep-UV photolithography. Thanks to this technique, we have achieved racetrack shaped micro-resonators coupled to suited access waveguides. We have assessed such MRs with different geometrical characteristics while changing, respectively, the coupling length (LC), the radius of curvature (R) and the width (w) of the guides. The chosen values for the set of parameters LC-R-w (in μm) are 5-5-3 and 10-10-3. The laser source used with the injection bench is a Gaussian broadband laser (λcentral = 790 nm, FWHM = 40 nm) allowing us to visualize several resonances at the same time in order to multiplex the relevant measurements. The transduced spectrum is then acquired with an optical spectrum analyzer (OSA) linked to a computer with Labview and MATLAB software recording and processing data in real time. Then, relevant characteristics to be tracked are the Free Spectral Range (FSR) and the transmitted energy; these quantities can be linked to the physical characteristics of the structure considering both the effective refractive index and the absorption coefficient. The experimental setup also includes various movies with a top-view imaging camera of the chip (MRs) recording the soft matter process steps, so as to correlate the changes in the transduced spectrum and the behavior of the condensed water mechanisms (condensation, coalescence and evaporation). Then, the chip is fitted with a temperature controller, so as to carry out measurements at different temperatures: 20, 24 and 28 °C.
Two consistent estimators for the skew Brownian motion

The skew Brownian motion (SBm) is of primary importance in modeling diffusion in media with interfaces which arise in many domains ranging from population ecology to geophysics and finance. We show that the maximum likelihood procedure estimates consistently the parameter of an SBm observed at discrete times. The difficulties arise because the observed process is only null recurrent and has a singular distribution with respect to the one of the Brownian motion. Finally, using the idea of the expectation–maximization algorithm, we show that the maximum likelihood estimator can be naturally interpreted as the expected total number of positive excursions divided by the expected number of excursions given the observations. The theoretical results are illustrated by numerical simulations.

Hintergrund Schmerzen treten im Sport sowohl als Folge akuter Verletzungen als auch in Form von chronischen Schmerzen durch Über- oder Fehlbelastungen auf. Sie kommen im Tanz häufig vor und stehen in Zusammenhang mit der hohen tanztechnisch bedingten, spezifischen Belastung des muskuloskelettalen Systems. Bisher fehlen Daten zu schmerzrelevanten Aspekten aus dem semiprofessionellen bzw. ambitionierten Breitensportbereich. Dies gilt gleichermaßen für die Tänzer als auch für die Tanz-vermittelnden (professionellen) Lehrkräfte. Ziel der Studie war es, Schmerzen bezüglich der Prävalenz, der Lokalisationen und des zeitlichen Verlaufs im nicht professionellen Tanzbereich bei weiblichen Tänzerinnen (T) und Tanzpädagoginnen (TP) zu eruieren.

Methoden Die quantitative Querschnittsbeobachtungsstudie mit deskriptivem Charakter erfolgte bei n = 153 semiprofessionellen Tänzerinnen und n = 149 professionellen Tanzpädagoginnen im Rahmen einer vollstrukturierten anonymen Online-Befragung.

Ergebnisse Jeweils über 70 % der Befragten gaben Schmerzen am Bewegungssystem im Kontext des Tanzens innerhalb der letzten 3 und 12 Monate an. Am häufigsten und stärksten waren jeweils der untere Rücken und die Kniegelenke betroffen. Im zeitlichen Verlauf zeigten sich sowohl bei den T als auch TP vorrangig über 6 Monate andauernde, häufig auftretende Schmerzen. Bei den TP waren die Schmerzen länger anhaltend, traten eher auch in Ruhe auf und waren eher in der Beweglichkeit und Belastbarkeit einschränkender als bei der Gruppe der T.

Diskussion In der Schmerzprävalenz sowie in den Schmerzlokalisationen sind die vorliegenden Ergebnisse sowohl bei den TP als auch T mit bisherigen Studienergebnissen aus dem professionellen Bereich vergleichbar. Gesundheitliche Risiken und damit verbundene (berufliche) Einschränkungen entstehen vor allem durch chronische Schmerzverläufe bei den TP. In der Gesundheitsversorgung von TP können daher die Behandlung und der Umgang mit chronischen Schmerzzuständen hinsichtlich der beruflichen Teilhabe dieser sehr bedeutsam sein.
Retrospektive Analyse von Risikofaktoren bei
Adeno-Tonsillektomie im Kindesalter
Authors: Knipping Stephan , Michaelis Franziska
Published: December 2018

Hintergrund Die Tonsillektomie zählt zu den in Deutschland am häufigsten
durchgeführten Operationen, deren gefährlichste Komplikation vor allem für
Kinder die Nachblutung darstellt. Die Bestimmung von INR und PTT erfolgt meist
nur noch in Ausnahmefällen.

Material und Methoden In einer retrospektiven, pseudonymisierten
Untersuchung aus einem 4-Jahreszeitraum wurden die Daten von Kindern und
jugendlichen Patienten mit Eingriffen am Waldeyerschen Rachenring erfasst.
Hierbei sollten anhand des präoperativen Fragebogens zur Blutgerinnungsanamnese
sowie des laborchemischen Screenings Risikofaktoren für Nachblutungen sowie für
ein von-Willebrand-Syndrom (vWS) identifiziert werden.

Ergebnisse Es handelte sich um 171 männliche und 137 weibliche Patienten,
bei denen vom 1. bis zum 13. postoperativen Tag bei 43 Kindern (14 %)
Nachblutungen beobachtet wurden. Davon traten 4,2 % innerhalb von 24 Stunden und
10,4 % nach 24 Stunden auf. Ein signifikant höheres Risiko für Nachblutungen
hatten Kinder mit anamnestisch häufigem Nasenbluten. Eine signifikant höhere
Nachblutungsrate bestand bei präoperativ pathologischem Hämoglobinwert. Für
Kinder mit vWS konnte ein signifikant erhöhtes Nachblutungsrisiko, festgestellt
werden.

Schlussfolgerungen Bei Vorliegen einer auffälligen Familienanamnese sowie
der Zusatzfragen an die Mutter des Blutungsfragebogens konnte ein signifikant
erhöhtes Risiko für ein vWS nachgewiesen werden. Hier empfiehlt sich die
Bestimmung der PTT sowie der PFA-100 und eine weitere vWS-Stufendiagnostik
anzuschließen. Auffällige Werte in der präoperativen Routinediagnostik,
besonders der Hämoglobinwert, können hinweisgebend für ein erhöhtes
Nachblutungsrisiko sein. Eine bestmögliche Risikoabschätzung für Nachblutungen
sowie dem vWS erfolgt durch eine gezielte Anamnese mittels standardisiertem
Fragebogen in Kombination mit einer gezielten Labordiagnostik.

2-Amino-5-(3’-indolomethylene)-1, 3 , 4 - oxadiazole (3) undergoes facile condensation with various aromatic aldehydes to gave 2-substitiuted arylidenylamino-5-(3’- indolomethylene) – 1, 3 , 4 – oxadiazole (4–8). Cyclocondensation of (4–8) with thioglycolic acid and triethylamine yielded 3-[5’-(3”- indolomethylene)- 1’, 3’, 4’- oxadiazol-2’-yl]- 2- (substituted aryl)-4- thiazolidinones (9–13) and 1-[5’-(3”- indolomethylene) -1’, 3’, 4’- oxadiazol - 2’- yl ] -4-(substituted aryl) -2- azetidinones (14–18). The structures of these compounds were established on the basis of analytical and spectral data. The newly synthesised compounds were evaluated for their anticonvulsant activity and acute toxicity.
Clinical Needs as a Starting Point for Different Strategies in Computational Drug Development
Authors: Portela César
Published: December 2018

Traditionally, the first step in the development of drugs is the definition of the target, by choice of a biological structure involved in a disease or by recognition of a molecule with some degree of a biological activity that presents itself as druggable and endowed with therapeutic potential. The complexity of the pathophysiological mechanisms of disease and of the structures of the molecules involved creates several challenges in this drug discovery process. These difficulties also come from independent operation of the different parts involved in drug development, with little interaction between clinical practitioners, academic institutions and large pharmaceutical companies. Research in this area is purpose specific, performed by specialized researchers in each field, without major inputs from clinical practitioners on the relevance of such strategy for future therapies. Translational research can shift the way these relationships operate towards a process in which new therapies can be generated by linking experimental discoveries directly to unmet clinical needs. Computational chemistry methods provide valuable insights on experimental findings and pharmacological and pathophysiological mechanisms, allow the virtual construction of new possibilities for the synthesis of new molecular entities, and pave the way for informed cost-effective decisions on expensive research projects. This text focus on the current computational methods used in drug design, how they can be used in a translational research model that starts from clinical practice and research-based theorization by medical practitioners and moves to applied research in a computational chemistry setting, aiming the development of new drugs for clinical use.
