Authors: Anjarsari Intan Ratna Dewi
Published: August 2022

ABSTRAKTeh sebagai minuman fungsional sejalan dengan tema hari keamanan pangan  2021 yang bertema Safe food today for a healthy tomorrow, yang menekankan bahwa produksi dan konsumsi produk pangan yang aman akan memiliki manfaat jangka panjang untuk kesehatan dan ekosistem untuk masa depan. Teh (Camelia sinensis L. (O.) Kuntze ) merupakan minuman yang kaya akan senyawa bioaktif  berupa antioksidan yang baik untuk kesehatan. Tidak hanya sebagai penghilang dahaga, tetapi kini teh berkembang sebagai minuman fungsional yang berperan dalam aspek kesehatan.  Jawa Barat sebagai produsen teh dengan produksi terbanyak di Indonesia tentunya memiliki potensi yang cukup besar dalam mengembangkan industri teh mulai dari hulu hingga hilir, baik untuk jenis teh hitam, teh hijau, ataupun teh putih.  Peningkatan kadar katekin sebagai antioksidan dari segi agronomi  sangat dibutuhkan  melalui inovasi dan riset yang terus menerus. Teh Indonesia khususnya Jawa Barat berpotensi untuk dikembangkan sebagai minuman fungsional,  terutama varietas Assamica yang memiliki kandungan antioksidan yang tinggi. Rekayasa budidaya tanaman teh sebagai minuman fungsional yang kaya antioksidan dapat dicapai melalui pemilihan klon, teknologi pemuliaan tanaman, penanaman pohon pelindung, optimalisasi lingkungan tumbuh serta diikuti oleh penanganan pasca panen, yakni pengolahan di pabrik serta teknik penyimpanan. Kata Kunci :  antioksidan, minuman fungsional, assamica. ABSTRACTTea as a functional beverage is in line with the theme of the 2021 food safety day, i.e., “Safe food today for a healthy tomorrow”, that emphasizes that the production and consumption of safe food products will have long-term benefits for health and ecosystem in the future. Tea (Camelia sinensis L. (O.) Kuntze ) is an antioxidant-rich beverage that are good for health. Recently, tea served not only as a thirst quencher but also as a functional drink that plays a role in health aspects. West Java as the highest tea producer in Indonesia certainly has considerable potential in developing tea industry from upstream to downstream, whether for black tea, green tea or white tea. Increasing levels of catechins as antioxidants from an agronomic perspective are needed through continuous innovation and research on tea. Indonesian tea, especially West Java, has the potential to be developed as a functional drink, especially the Assamica variety with its high antioxidant content. Pre-harvest modification on tea plant to form antioxidant-rich functional beverage can be achieved through clone selection, plant breeding technology, planting protective trees, optimizing the growing environment and followed by post-harvest handling through factory processing as well as storage techniques.Key words :  antioxidants, assamica, functional beverage
Nation brand image and trust level of foreign citizens
Authors: Damayanti Trie , Dida Susanne , Hidayat Dadang Rahmat , Cho Sung Kyum
Published: August 2022

The state is an organization with a power structure and the population as members of the state. The state itself is an entity that interacts with other entities that can consist of other countries and their inhabitants, rules, and products. Because of this, a country needs an identity that can distinguish the country from other countries. The identity of a country is not the same as the identity of a product because a country is bound by history and images attached to foreign citizens’ minds. This inherent image is usually used to form a nation’s brand image. This study aims to discover how Malaysia’s nation brand image contributes to the trust of foreign nationals visiting their country by using a constructivist qualitative approach as a research method. It turns out that the results of the study show that the most powerful thing in determining Malaysia’s brand image is not tourism promotion. As a country with an image of different cultures, Malaysia will use this potential to visualize its tourism promotion to keep those images stronger. However, the experience of Indonesian citizens in interacting with the Malaysian state, with infrastructure, state norms, and citizens, is a determinant of how Indonesian citizens perceive Malaysia. What is inherent in the results of the experience of interacting in Malaysia is what Indonesian citizens will convey to others. Therefore, a comprehensive strategy is needed to build a national brand image of Malaysia because what sticks in mind as an image of Malaysia in foreign nationals will show their trust in the country.

Da concordância entre o velho e o novo: ler a tradição em Uma viagem à Índia, de Gonçalo M. Tavares
Authors: De Almeida Catarina Nunes
Published: August 2022

Em Uma Viagem à Índia (2010), Gonçalo M. Tavares propõe-nos um exercício de revisão e desconstrução do cânone literário. Tomando por modelo Os Lusíadas de Luís de Camões, esta obra vem apelar à revisitação da mitologia cultural e literária -- não só portuguesa, mas ocidental — através de um conjunto de textos do nosso imaginário de leitores. O intuito deste artigo é apresentar uma análise do texto de Gonçalo M. Tavares, para mostrar como na sua obra a tradição é virada do avesso, instigando à releitura, graças à interação dialética que o presente mantém com o passado. Procurarei demonstrar que a compreensão de Uma viagem à Índia depende necessariamente da verificação de certos procedimentos que caracterizam as relações ``entre textos''. O objetivo é, pois, refletirmos acerca do trabalho de transformação e de assimilação realizado em torno desse texto centralizador, Os Lusíadas, tendo em conta os quinhentos anos que nos separam dele.

Information about larva and nymphal stages as well as additional descriptions of adults of four littoral species of the families Fortuyniidae, Selenoribatidae and Podacaridae found around the coast of South Africa are provided. Juveniles of Fortuynia elamellata micromorpha are well in accordance with the morphology of other known juveniles of Fortuynia, but the larva of the former shows distinctly barbed rostral setae, a trait which lacks in all the other species. Adults of the South African Selenoribates divergens are similar in morphology to the Egyptian specimens, except for the presence of small rostral humps, anterior notogastral tubercles and the position of lyrifissure ih. These differences are presently considered to be only geographic variation. Juveniles of Sel. divergens can be easily distinguished from juveniles of other known Selenoribates species by the presence of a spinose clavate bothridial seta and branched notogastral setae in deuto- and tritonymph. Due to the loss of type specimens of Schusteria ugraseni, a neotype was designated. The juveniles of this species are very similar to those of Schusteria littorea and Schusteria melanomerus, but differ in amongst others the anoadanal and leg setation. Adults of Halozetes capensis show strong variation in the length of dorsal setae and juveniles of this species differ significantly from others in the number of prodorsal and gastronotic porose sclerites. Finally, a table is provided listing all ameronothroid species with known juvenile stages.

Published: August 2022

Problems related to air quality in large urban agglomerations (e.g., high concentration of pollutants, the urban heat island phenomenon) make it necessary to take comprehensive measures to improve air exchange in urban areas. The paper concerns the relationship between wind phenomena observable in cities and the geometrical features of building development. The knowledge on the subject is already well-founded and has been intensively developed. Regardless, it remains relatively poorly applied to urban planning. Based on the analysis of source literature, the classification of features and spatial elements of building development that are crucial for ventilation is conducted in the following paper. Five different cities are also analyzed regarding how the air exchange improvement policy should be pursued through conscious building development shaping. The cities selected for analysis include Warsaw and Cracow in Poland, a large agglomeration of New Dehli in India, the experimental Masdar City in the United Arab Emirates, and the newly designed Jätkäsaaridistrict of Helsinki. Based on the example of the above cities, the paper investigates the possibilities of combining spatial features of building development that are essential to aerodynamics, in order to create effective ventilation systems.

Published: August 2022

Rice husk disposal has become a great challenge for Pakistan being one of the largest rice producer across the globe. Rice Husk Ash (RHA) contains sufficient pozzolanic properties which opens up opportunities for its usage as cementitious material as partial replacement of Ordinary Portland Cement (OPC). In this research RHA was added as cement replacement in different percentages by weight of cement i.e. 0%, 6%, 12%, 18% and 24% at constant mix ratio of 1:2:4 and water-cement ratio of 0.6 that is M15 grade concrete with a target strength of 15-20 MPa. The properties of concrete like workability, compressive strength, tensile strength, flexure strength, and water permeability were investigated by casting standard concrete samples in the form of cubes, cylinders and beams in addition to cost comparison study The outcomes show that workability of fresh concrete increases with an increase in RHA content and almost all concrete properties studied in this research gave more favorable results at 6% replacement level compared with the control mix.
Theoretical Models of PV-EC Windows Based on the Architectural Analysis of PV-EC Technologies
Authors: MARCHWIŃSKI Janusz
Published: August 2022

The paper provides an architectural analysis of the switchable PV-EC glazing technology based on combining photovoltaic (PV) technology with electrochromic (EC) glazing. The integration of these technologies is considered to constitute future-oriented façade solutions in shaping buildings that are energy-saving and environmentally friendly. The paper aims to define theoretical models of windows using PV-EC technology as solutions adequate from the architectural point of view. To achieve this goal, a comparative analysis of three PV-EC technologies was conducted, i.e., side-by-side (SBS) technology and tandem technologies, namely tandem solid technology (TST) and tandem liquid technology (TLT). The analysis covered functional aspects related to such issues as thermal and visual comfort, energy and aesthetics. The analysis led to extracting the features of the three compared technologies; consequently, their strengths and weaknesses were determined. As a result, seven window models were developed which, based on the above analysis and the insights derived from it, were recognized as the solutions in which the potential of PV and EC technology is best used. The dominant advantages of SBS, being the most developed technology and one with the greatest flexibility in construction applications, are indicated. The research is of a contributory nature, as it constitutes the basis for further numerical and simulation research. Such studies may prove useful to architects in making design decisions, especially at the initial design stages. However, at the current stage of technological development, the study mainly serves as an introduction to further research on improving the PV-EC properties towards integration with the building and its architecture.

Published: August 2022

Due to the so-called road run-off, many various contaminants including Bisphenol A (BPA) and Pyrene (PYR) could enter the environment and retention basins. It was also suggested in the literature that their removal by using conventional treatment methods could be problematic, and modern techniques should be developed. In this study, the first attempt to remove BPA and PYR by using ultrasonication as a single process and with UV irradiation assistance was performed. The results showed that after 30 min of sonication, the degradation rate of BPA reached 92% while PYR was completely removed, however, after 1 min of the treatment degradation rate of BPA was significantly higher than PYR. In the study effect of pulsed ultrasound was also evaluated and it was found that its effectiveness in micropollutants removal could be higher than ultrasonication in continuous mode. Research revealed that the maximum removal rate of BPA and PYR was obtained during the ultrasonication process combined with UV irradiation-30 min of treatment resulted in 95% of BPA degradation. However, toxicity assessment showed that with an increase in the treatment time, an increase of toxic effects occurs. This phenomenon might be related to degradation of by-products formation which were identified in the study.
The Importance of Recovery of PGMS from Catalysts – A Case Study of Recycling Network in Poland
Authors: GENEROWICZ Natalia
Published: August 2022

Combustion engines are the main driving force of passenger cars, trucks or buses. Engines burn fuels, and as a side effect, release many pollutions to the atmosphere. Car manufacturers had been aware of a need of lowering the amount of exhaust fumes. This brought on the market the first catalytic converters. Nowadays automobile catalyst manufacturing is the largest sector of demand of PGMs (mainly platinum, palladium and rhodium), and unfortunately consumption and future demand of there critical metals is getting higher.

Over the past two decades, most countries around the world have developed and implement solutions that would minimize the impact of the growing number of cars on the environment. One solution contributing to this is the organisation of an end-of-life car collection and recycling network, which is now an integral part of automotive industry. The main drivers for the development of such network were stricter environmental regulations and economic conditions.

The development of recycling is also becoming more popular in Poland. However, catalyst recycling system is still not transparent to all stakeholders. Due to the huge variety of catalysts and their different structure and composition of elements from the PGMs group, the valuation of their price before they are recycled is not obvious. This raises a lot of controversy and does not inspire trust among those who recycle their catalysts.

The aim of this work is to show how the management of used catalytic converters looks like in Poland and how developed is network of catalysts recycling in Poland. At the same time this will show how important it is in terms of a circular economy and the recovery of valuable raw materials from a group of PGMs.
Firefighters’ Protective Clothing – Water Cleaning Method vs Liquid CO2 Method in Aspect of Efficiency
Authors: SZMYTKE Ewelina , BRZEZIŃSKA Dorota , MACHNOWSKI Waldemar , KOKOT Szymon
Published: August 2022

Multilayer material of firefighters’ Personal Protective Equipment (PPE) creates obstacles in toxins disposal while washing. This leads to long-term exposure and health risks to firefighters. The University of Leuven conducted experiments that showed the highest concentrations of toxins in the bodies of firefighters who wore the most contaminated clothes. In contrast a non considerable increase of toxins was observed in the group using LCO2 decontaminated clothes. Another study run in Finland in 2018 analyzed water cleaning of PPE and concluded that it was not efficient in providing safe and clean firefighters’ clothing. To check the efficiency of LCO2 cleaning, a set of laboratory tests on worn-out Polish fire gear was undertaken. The results presented in this paper confirmed that the clothes were clean enough to consider them safe for use.
Genetic basis of acute myeloid leukemia (AML): The most common molecular changes in patients with normal karyotype
Authors: Matiakowska-Bryk Karolina , Bartoszewska-Kubiak Alicja , Haus Olga
Published: August 2022

Acute myeloid leukemia (AML) is a clonal disorder that results from errors in proliferation and differentiation of bone marrow stem cells from myeloid lineage. According to the Gilliland “two-hit” model, genes of both groups related to proliferation (e.g., FLT3) and differentiation (e.g., CEBPA) must be mutated for full development of AML. The genetic background of AML is very complicated and varied, from single nucleotide mutations or changes in gene expression to cytogenetic aberrations. The DNA sequencing results enable identification of important gene alterations that occur first and may lead the whole leukemogenesis (driver mutations). Some of them have prognostic significance – that is, they are related to the overall survival (OS), complete remission rate, and event-free survival (EFS). The most common molecular changes in AML are mutations in NPM1, CEBPA, FLT3, and DNMT3A. Alterations in NPM1 gene are associated with a good prognosis but simultaneous mutation in FLT3 may change this prognosis. DNMT3A mutations are very often correlated with NPM1 mutations and are associated with short OS.
Countercyclical fiscal policy and gender employment: evidence from the G-7 countries
Authors: Akitoby Bernardin , Honda Jiro , Miyamoto Hiroaki
Published: August 2022

Would countercyclical fiscal policy during recessions improve or worsen the gender employment gap? We answer this question by exploring the state-dependent impact of fiscal spending shocks on employment by gender in the G-7 countries. Using the local projection method, we find that, during recessions, a positive fiscal spending shock increases female employment more than male employment, contributing to gender employment equality. Our findings are driven by disproportionate employment changes in female-friendly industries, occupations, and part-time jobs in response to fiscal spending shocks. The analysis suggests that fiscal stimulus, particularly during recessions, could achieve the twin objectives of supporting aggregate demand and improving gender gaps.

Slaughterhouses produce wastewater containing high organic matter, which has the effect of polluting water and the surrounding environment. Slaughterhouse wastewater treatment can be done biologically, namely biofiltration, by utilizing microorganisms and chlorination. Efforts in wastewater treatment continue to be developed. This study aimed to determine the effectiveness of biofiltration processing techniques with an Aerobic Fixed-Bed Reactor (AFBR) with pumice stone media combined with chlorination to reduce the levels of COD, BOD, TSS, ammonia, and coliform bacteria. The method applied was to use biofilms from the seedings on pumice with variations of with or without the addition of active suspension, aeration system treatment with time variations, and the addition of chlorine with variations of active chlorine doses. The results showed that the addition of active suspension in the process produced the best biofilm, and was effective in reducing the levels of COD, BOD, TSS, and ammonia. The best reduction of COD levels was at the 36th hour at 81.60 mg/L with an efficiency of 57.45%, BOD at the 36th hour was 24.67 mg/L with an efficiency of 65.74%, TSS at the 42nd hour was 54.0 mg/L with an efficiency of 85.66%, and ammonia at the 42nd hour of 1.5539 mg/L with an efficiency of 88.29%. Chlorination after the treatment with AFBR resulted in a decreased number of coliform bacteria from 1,100 MPN/100 mL to 0 MPN/100 mL with 100% efficiency. The chlorination process resulted in the optimum chlorine dose of 165 ppm with a chlorine residual of 28.80 mg/L. Thus, the treatment for 36-42 hours on AFBR followed by chlorination with a chlorine dose of 165 ppm was relatively effective in reducing COD, BOD, TSS, ammonia, and coliform levels of bacteria in slaughterhouses wastewater.

Perubahan Identitas Tempat dan Konflik Ruang di Pinggiran: Studi Awal Tentang Urban Habitus dalam Transformasi Ruang di Kota Depok, Jawa Barat
Authors: Setiadi Hafid
Published: August 2022

The study aims to reveal ideas of structure contained in the idea of Habitus as expounded by Bourdieu. The concept is applied to urban transformation in Depok, West Java, a rapidly expanding suburb of Jakarta. In the process, actor dominance, and socio-cultural resistance in the process of urban transformation emerge as significant processes. Discussion of findings derived from observations in the field, literature reviews, and in-depth interviews are deployed, with an emphasis on the symbiotic connection between place identity and conflicts over space which occurs due to imbalances in the exercise of power. Accordingly, notions of “structuring structure” and “structured structure,” used in the study show that changes in physical performance, architectural design, and building function are reducing place identity. Much depends on the depth of spatial associations embodied by people regarding their history and its contribution to a specific place. However, resilience of place identity is able to absorb conflicts over space as a reflection of symbol competition among urban actors for strengthening their resistance to power struggles.

Proses Terbentuknya Teritorialitas pada Permukiman Padat Penghuni di Kampung Jawa, Denpasar
Authors: Mentari Indriani Ni Ketut Ayu Intan Putri
Published: August 2022

Territoriality is a pivotal element in the study of architecture. It relates to functions that personify one's spatial behaviour in achieving a desired level of privacy. Territoriality works in parallel with a sense of belonging as well as one's controlling and defensive attitudes toward a supposedly claimed spatial context. In the populated urban settlement of the overly crowded Kampung Jawa of Denpasar City, access to space becomes a privilege its occupants hold dearly. The growing population has consequently escalated its demand for space that has no practical resolution given the amount of land available. In turn, this has affected people's manner in sharing, adapting, and conceiving their space. Grounded by such in such conditions, this study aims at identifying various territorial phenomena that take place in Kampung Jawa, as well as the spatial and social adaptations associated with each observed territorial setting. The study implements a qualitative approach and explains its findings in a descriptive manner.

Objective: In this study, it was aimed to determine the age of the onset of crown calcification of third molars in children aged 5-15 years in Turkey, and to evaluate the development status of third molars by age.Material and Methods: Panoramic radiographs of the first 1024 patients between the ages of 5 and 15 years were evaluated. The development (calcification) of third molars was classified according to the Demirjian method.Results: When the onset age of the stages for maxillary and mandibular third molars were compared, no statistically significant difference was found (p≥0.05). In addition, although no statistically significant difference was found between genders regarding the age of calcification onset of third molars, it was observed that teeth #28 and #48 developed in boys approximately one year before girls (p≥0.05). When the onset age of the stages for maxillary and mandibular third molars were compared, no statistically significant difference was found (p≥0.05). Concerning stage 5, in which the furcation zone of third molars begins to calcify, although not statistically significant, all the maxillary and mandibular third molars were seen earlier in girls than boys.Conclusion: It was found that the maxillary third molars on the right side developed earlier than mandibular third molars.

Amaç: Enfeksiyöz gastroenteritler, özellikle çocuklarda morbidite ve mortalitenin en önemli nedenlerinden biridir. Rotavirüs ve enterik adenovirüsler, enfeksiyöz gastroenteritlerin önemli viral etkenlerindendir. Çalışmamızda, akut gastroenterit ön tanısı ile laboratuvara gönderilen gaita örneklerinde; rotavirüs ve adenovirüs pozitifliği ile etkenlerin cinsiyet, yaş ve mevsimsel dağılımının belirlenmesini amaçladık.Gereç ve Yöntemler: Temmuz 2015-Haziran 2019 tarihleri arasında çeşitli kliniklerden akut gastoenterit ön tanısı ile mikrobiyoloji laboratuvarına gönderilen gaita örnekleri rotavirüs ve adenovirüs varlığı açısından incelendi. Gaita örneklerini incelemede kalitatif immunokromotografik yöntem ile çalışan Simple/StickRota Adeno (Operon, İspanya) kiti kullanılmıştır. Çalışma verilerini retrospektif olarak inceledik. İstatistiksel değerlendirmeler, “Ki-Kare (Chi square) testine” göre yapıldı.Bulgular: Çalışmaya dahil edilen 5294 örneğin, 472’sinde (%8.91) rotavirüs pozitifliği; 237’sinde (%4.4) ise adenovirüs pozitifliği saptanmıştır. Rotavirüs pozitifliği 13-24 ay arasında 104 (%22) ve 2-5 yaş arasında 116 (%24.5); adenovirüs pozitifliği 2-5 yaş arasında 38 (%16) ve 18 yaş üstünde 85 (%35.8) olarak saptanmıştır. Mevsimsel olarak rotavirüs enfeksiyonlarının 179’u (%37.9) ilkbahar, 153’ü (%32.5) kış; adenovirüs enfeksiyonlarının 65’i (%27.4) kış, 61’i (%25.8) yaz aylarında saptanmıştır.Sonuç: Viral gastroenterit etkenlerinden rotavirüs ve adenovirüs, dışkıda bakılan antijen testleriyle kolaylıkla tespit edilebilir. Rotavirüs ve adenovirüs pozitiflik oranlarının, yaş, cinsiyet ve mevsimsel dağılımlarının bilinmesi bölgesel ve ülke çapında verilere katkı sağlayacaktır.
