Published: September 2021

Concrete is a building structure whose development is relatively fast because it is an important part of development. Shells of keong sawah, which are pests for rice plants, can also be used as an added material in making concrete because they contain a large amount of calcium carbonate. This study aims to determine the effect of adding shells of keong sawah on the compressive strength of concrete with a variation of 0% and 15% on the weight of cement. This research was conducted using a cylindrical concrete specimen with a diameter of 15 cm and a height of 30 cm. The results showed that the addition of 15% powder shells of keong sawah had an increase in compressive strength, namely 31.1 MPa when compared to the 0% variation with a compressive strength value of 25.6 MPa. It can be concluded that in this study the addition shells of keong sawah 15% by weight of cement can increase the compressive strength of the concrete.

Published: September 2021

Development of The Syamsudin Noor Airport Project in Banjarmasin is one of the largest projects in Banjarmasin, South Kalimantan. This project applied BIM-based cost estimation on a steel roof structure. However, the cost estimation for this steel roof structure is applied conventionally. The BIM-based cost estimation could have been applied in collaborating a building information becomes unity in one model. This research will raise the issue of applying BIM-based cost estimation at The Syamsudin Noor Airport Project to find out the effectiveness calculation of cost estimation conventionally and BIM-based cost estimation. The report result by 3D modeling of Tekla is quantity take-offs using as a data for processing the cost analysis conventionally. Whereas the 3D model made by Tekla will be exported to Revit through the interoperability of IFC or application of extention of Tekla warehouse that is “Export to Revit Geometry” for the processing the BIM-based cost estimation analysis. The unit price for the cost calculation is acquired by list price (AHSP or subcontractor value). The result of these both cost calculation, there are large enough difference in cost of these both calculations. Difference of conventional calculations and BIM-based cost estimation using Revit worth Rp 3,690,741,474 - Rp 5,047,206,780 with a percentage of 14% - 20%. Cause of these large enough differences in cost due to the model exported is only 90% succeeded.

Implications of Water Tariff Structures on Water Demand in Santa Cruz Island (Galapagos Archipelago)
Authors: Reyes Maria F.
Published: September 2021

The island of Santa Cruz, located in the Galápagos Archipelago has experienced a significant increase in tourism with consequent growth of the local population over the past two decades. The rapid increase in the number of hotels and restaurants raised pressure on the water demand needed to satisfy the customers’ needs. The municipality of Santa Cruz has not been capable of coping with current expansion rates in order to provide good quality water services. Financial constraints, limited personnel, and tariff structures are the main reasons that restrict the capacity of the Department of Potable Water and Sanitation (DPWS) to manage the water supply system. There are two main settlements on the island are Puerto Ayora and its suburb, Bellavista, with a total population of approximately 14,500 and independent water supply systems. Puerto Ayora has a fixed-priced tariff per month, for categories established by the municipality. On the other hand, Bellavista has a metered system, with fixed consumer costs Yet, approximately 32% of water meters are faulty. Consequently, water demand in these two settlements varies significantly, which is likely influenced by the difference in tariff structures. This manuscript assesses the difference in tariffs between the two settlements. Furthermore, the impacts on revenues due to faulty meters (Bellavista) and fixed tariffs (Puerto Ayora) are quantified. In addition, several scenarios have been developed and analyzed in order to examine the benefits. Finally, the information regarding overdue bills and willingness to pay by the different categories of users has been examined. Results show that the revenues from water supply vary extensively between the two settlements. Due to the fixed tariffs in Puerto Ayora, the estimated cost per cubic meter of water varies depending on the specific category and estimated quantities of water used. In the case of Bellavista, water meters should be managed better and have regular maintenance. The high percentage of faulty meters gives an extra deficit to the municipality.
A nemzeti kisebbségek parlamenti képviselete Európában, különös tekintettel a Jugoszláv utódállamokra
Authors: Heka László
Published: September 2021

Az általunk vizsgált térségben némely kisebbségek részéről hiányzik a nemzeti államhoz való politikai hűség, amelyet az államalkotó nemzet elvárna tőlük, ezért is alakultak ki azok a sztereotípiák, amelyek szerint a nemzeti kisebbségek szeparatisták, főként olyan esetekben, ha az anyaországuk szomszédos állam. A korábbi három szocialista szövetségi állam – Jugoszlávia, Szovjetunió és Csehszlovákia – felbomlása ezt részben bizonyította is, hiszen a délszláv államban sokéves véres háború folyt. E három országból a népek önrendelkezési és elszakadási joga alapján 24 új utódállam keletkezett, amelyek nemzetközi elismerésének feltételei között szerepelt a nemzeti kisebbségek jogainak tiszteletben tartása. Jelen tanulmányban górcső alá vesszük a nemzeti kisebbségek parlamenti képviseletre vonatkozó szabályozását a posztjugoszláv országokban és annak kihatását a parlamenti képviseletükre és a társadalmi életre.

Investigating the Relationship between Proficiency Level and Perceived Test Consequences: A Case Study of Iranian High School Students
Authors: Khodabakhshzadeh Hossein , Khosravani Mahmood
Published: September 2021

Aimed at promoting the consequential validity of high-stakes test, unexpected aspects of assessment process which negatively affect the learning process have been investigated by researchers in the last decades. Since discovering those variables that contribute to adverse test consequences is necessary for any successful intervention, the current study was an attempt to shed light on the relationship between proficiency level of examinees and their perception of test impacts.  To this purpose, 63 third grade male students studying for a high-stakes exam were selected through convenience sampling from three different high schools in the city of Birjand. A teacher developed proficiency test was then administered and participants were either assigned to high-proficiency group (N=34) or low-proficiency group (N=29). Then, using an interview protocol and conducting a content analysis of the interviews, students were either placed at social or psychological impact groups on the bases f the frequency of their answers to different items of the interview. The obtained data were entered into SPSS (version 21) and analyzed through Chi Square test to determine the goodness of fit. A significant interaction was found (X2 (1) = 6.647, p = 0.01). It was concluded that high proficiency students are more likely to perceive test consequences (54.0%) than low-proficiency group (46%). Besides, on the basis of Phi and Crammers’ V symmetric measures, the strength of the association between the variable was 0.325 which shows a medium effect of proficiency level on type of perceived test consequence. These findings have implication for language teachers, language learners, researchers and educational decision makers.
RETHINKING TRADITIONAL SCIENCE TEACHING THROUGH INFUSING ICT LEARNING EMBEDDED BY A ‘LEARNING-AS-DESIGN’ APPROACH
Authors: du Plessis André
Published: September 2021

The South African Department of Basic Education (DoBE) has been promoting constructivist learning principles, the development of higher order thinking, the implementation of ICT (Information and Communication Technology) (Department of Education, 2004; Du Plessis, 2014) and the development of critical outcomes such as problem solving, critical thinking, collaboration, self-management, finding and analysing information, developing effective communicating skills, assisting learners to use science and technology effectively as well as promoting effective learning strategies (Department of Education, 2004). The use of ICTs to promote teaching and learning has also been high on the agenda of the DoBE (2004; 2007). However, it appears that the use of ICT within South African schools is ‘bolted-on’ on to the curriculum as an added extra, resulting that integration with school subjects is minimal (Du Plessis, 2010). The above is probably prevalent outside the South African context too in many other schools all over the globe.

Published: September 2021

The rapid expansion of social networking websites (SNW) is raising several issues regarding the influence it has on the modern school. As many authors mentioned, the proliferation of social networks among university people is changing the educational processes. In order to find out how Facebook could support education, a social learning perspective is needed. In turn, this requires to measure the social capital and to analyze its educational potential. The aim of this research is to elaborate a theoretically grounded and empirically validated multi-dimensional model, measuring the social capital that is embedded in the Facebook networks of Lithuanian university students. This is a pilot research carried out between September and December, 2014. In this respect, the research limitation reveals itself; therefore, a wider theoretical and empirical research is necessary, analyzing the usage of Facebook in the university student population. The research is significant, because it is prepared and validated a multidimensional model of the bridging social capital as perceived by university students that are using Facebook.

THE EFFECT OF CONCEPT CARTOONS EMBEDDED WITHIN CONTEXT-BASED CHEMISTRY: CHEMICAL BONDING
Authors: Ültay Neslihan
Published: September 2021

The aim of this study was to investigate the effect of concept cartoons embedded within context-based learning approach on 8th grade students’ alternative conceptions of “chemical bonding”. Within a nonequivalent pretest-posttest control group design, the study was conducted with 45 8th grade students. To gather data, Chemical Bonding Concept Test (CBCT) with 16 multiple choice questions and clinical interviews with 5 open-ended questions was used to probe their conceptions. Clinical interview questions were prepared in parallel with the same alternative conceptions asked in the CBCT. At the end of the study, context-based approach was found effective at remedying alternative conceptions about chemical bonding. On the other hand, although concept cartoons are found powerful tools to remedy alternative conceptions about chemical bonding, they did not show an extraordinary effect. This suggests that we may need to use more than one intervention method to effectively remedy the alternative conceptions in chemical bonding.
Key words: alternative conception, chemical bonding, concept cartoons, context-based approach.

This article presents the results of a pilot research how the entrepreneurship is perceived by the participants of entrepreneurship courses. Also we have researched their previous (entrepreneurial) background and its relevance on enabling market entrance. We had two target groups: self financed students of Open University and participants in entrepreneurship course financed by European Social Foundation. Lifelong learning is a socio-personal process as we associate our thoughts and actions to our earlier experiences but on the same time revising that experience. The aim of this article is to explore how to teach entrepreneurship in lifelong learning process and to explore it in participants’ perspective. In empirical part authors used questionnaire with 77 statements with persons being admitted to some entrepreneurship courses. The respondents were asked to express their opinion on a five-point Likert scale. The data has been discussed in the context of the related literature. We discuss what learning methods are most effective - to learn about, for or through/within entrepreneurship (Hyrsky & Kyrö, 2005; Gibb, 1999; Hytti & O’Corman, 2004, Rae, 2004).

O tempo e o Direito do Trabalho no Brasil da pandemia de Covid-19: quatro teses inspiradas em François Ost
Authors: Soares José Luiz
Published: September 2021

Trata-se de uma reflexão inspirada na teoria de François Ost sobre como a noção de tempo pode contribuir para pensar o Direito do Trabalho. São apresentadas quatro teses a respeito da relação entre o tempo e a situação do Direito do Trabalho no Brasil durante a pandemia de Covid-19: 1) O neoliberalismo vem subvertendo os sentidos conferidos pela Constituição Federal de 1988 para o ordenamento jurídico-político brasileiro e essa subversão teve um capítulo à parte durante a pandemia. 2) O enfrentamento da pandemia se deu com uma grande aceleração do tempo jurídico, o que deteriorou o Direito do Trabalho. 3) Na conjuntura da pandemia, o choque entre diferentes temporalidades fomentou desigualdades e vulnerabilidades. 4) O neoliberalismo e a aceleração do tempo jurídico trouxeram sérios impactos para as possibilidades de mobilização coletiva e para a democracia. Para desenvolver a reflexão, foram analisadas medidas provisórias, leis trabalhistas, ações judiciais, estatísticas socioeconômicas, matérias jornalísticas e entrevistas com atores sociais selecionados.

Published: September 2021

A case-control cross-sectional study was carried out to observe the changes in serum calcium, albumin and alkaline phosphatase levels of postmenopausal women compared to their premenopausal counterparts. This is to enable us ascertain the relative risk of developing osteoporosis in postmenopausal women in Bangladesh. One hundred and eighteen (118) apparently healthy females (59 premenopausal=control and 59 postmenopausal=case) were selected for the study. The study was carried out in the Department of Biochemistry, Mymensingh Medical College in cooperation with the Department of Gynecology, Mymensingh Medical College Hospital and Community Based Medical College Hospital Bangladesh during the period from January to December 2009. Data were collected through clinical evaluation from pre-selected questionnaires. Fasting venous blood samples were taken for laboratory investigations. Serum calcium and albumin was determined using colorimetric method and enzymatic end point method was used to determine serum alkaline phosphatase levels. Statistical significance of difference between two groups were evaluated by using Student's unpaired 't' test with the help of SPSS software package. The results showed statistically significant decrease in serum calcium and albumin (p<0.01) of menopausal women compared to reproductive age group. The postmenopausal women had significantly higher (p<0.01) concentrations of serum alkaline phosphatase than the premenopausal women with regular menstruation. Therefore, it can be concluded that menopause leads to the increased risk of osteoporosis by decreasing serum calcium and albumin and by increasing alkaline phosphatase levels. The decreased serum calcium and increased alkaline phosphatase levels indicate that menopause is an independent risk factor for developing osteoporosis in women of Bangladesh.

Published: September 2021

There are few case reports regarding star fruit's nephrotoxicity and neurotoxicity in chronic kidney disease patients. Star fruit (Averrhoa carambola) is commonly consumed as a herbal remedy for various ailments in tropical countries. However, the dangers associated with consumption of star fruit are not commonly known. Although star fruit induced oxalate nephrotoxicity in those with existing renal impairment is well documented, reports on its effect on those with normal renal function are infrequent. We report two unique clinical presentation patterns of star fruit nephrotoxicity following consumption of the fruit. The first patient is a 52 year-old male diabetic patient who had normal renal function prior to developing acute kidney injury (AKI) after consuming large amount of star fruit juice at once for remedy of diabetes. The second patient, a 27 years old young male who developed acute kidney injury following star fruit ingestion in empty stomach. One case needed 4 sessions of hemodialysis another case recovered over 2 weeks without the need for haemodialysis. Consumption of star fruit, especially on an empty stomach or in a state of dehydration may precipitate acute kidney injury. A history of star fruit ingestion must be actively looked for in patients presenting with unexplained acute kidney injury. The use of star fruit as a therapy for diabetes should be discouraged.

ABSTRACTPumpkin (Cucurbita moschata (Duch.) Poir ) is one of the vegetables that is rich in β-carotene as a precursor of vitamin A and has a fairly high carbohydrate content. Pumpkin processing can be done to produce various kinds of products, one of which is cake. Cake is a baked dough and liquid dough made from flour, sugar, salt, ingredients, shortening, milk, eggs, and aroma enhancer. This study aims to determine the levels of β-carotene contained in pumpkin cake and to determine the acceptability of β-carotene in pumpkin cake. This research is an experimental research. The experimental design used was Completely Randomized Design (CRD) with 1 control 4 treatments and each treatment was repeated 3 times. The research phase consisted of making flour and making cake. Data collection methods include organoleptic tests and β-carotene tests. Data were analyzed using analysis of variance / ANOVA to determine differences in quality, and if there is an influence then proceed with the Tukey test. Organoleptic test results show that the best treatment of pumpkin cake in terms of color is A1 with a value of 3.88, in terms of aroma namely A0 with a value of 3.92, in terms of texture is A0 with a value of 4.28 and in terms of taste is A0 with value of 4.16. As for the β-carotene test, the treatment of pumpkin cake with the highest β-carotene content was found in A4 with an average of 0.262 and the lowest level was in A0 with an average of 0.018. Based on research data, pumpkin flour is worthy of being used as an alternative source of flour because the resulting cake meets SNI quality standards both in terms of color, taste, aroma, texture and β-carotene content.Keywords : Cake, Pumpkin, β-Carotene, Organoleptic

O presente estudo tem como objetivo discutir sobre a importância de grupos operativos, a partir do trabalho social, em um grupo de idosos que residem e convivem em um asilo. Este estudo, derivado de um Trabalho de Conclusão de Curso, visa contemplar o processo de conhecimento vivenciado durante o estágio curricular, sendo que para isto, foi dividido em capítulos. O primeiro faz um resgate histórico da velhice através dos tempos, como ela é vista por diferentes sociedades, trazendo também as políticas de atendimento ao idoso e como estas vêm se efetivando no contexto social. Salienta o crescimento do número de casas geriátricas devido ao crescente envelhecimento e em especial da instituição asilar Asilo da Velhice Nossa Senhora Medianeira e sua trajetória histórica. O segundo capítulo destaca os grupos e seu sentido na sociedade de uma maneira mais ampla, focalizando em grupos operativos que foram os grupos desenvolvidos com os idosos da instituição asilar. Traz também a importância do desenvolvimento destes grupos na terceira idade e quais as mudanças que possibilitam ao idoso participante. No terceiro capítulo, são feitas considerações acerca do processo de trabalho do Serviço Social, trazendo a vivência de estágio desde a observação até a implementação do projeto de intervenção, dando ênfase ao produto final, obtido através deste processo de trabalho. A metodologia deste estudo qualitativo é delineada a partir de um estudo de caso, utilizando o diário de bordo como instrumento de coleta de dados, neste estudo intitulamos como “diário de campo”, que posteriormente foram discutidos e relacionados com a bibliografia pertinente. Com isso, foi possível identificar a necessidade de um trabalho voltado aos idosos da instituição por meio da aplicação de grupos operativos, assim como avaliar este processo de trabalho positivamente, com a efetivação do grupo, que resulta no fortalecimento e na autonomia aos seus participantes.

Authors: Emanuel Ulu
Published: September 2021

This study aimed to determine whether the supervision activities by supervisors in Subject Teacher Organization (or MGMP) could improve teachers' abilities to implement the active, creative, effective, and fun learning (or PAKEM). To obtain the data needed, this study involved 34 teachers of SMA Negeri 1 Tasifeto Barat and was carried out in three months, starting from 18 August 2019 to 13 October 2019. The results of this study indicated that the teachers’ ability to prepare PAKEM model increased after coaching was carried out by supervisors in the MGMP. The increase was proved by an increase in the average percentage of lesson plan (RPP) preparation, that was 61.19% in cycle I and 67.77% in cycle II as well as the teachers’ ability to compile learning scenarios and components in designing classroom management by determining the types of learning activities that provided opportunities to involve students with detailed and challenging steps for improvement. Therefore, it was suggested that supervisors and school principals took the advantage of the school MGMP forum as a target for teacher training to improve their quality of learning activities and teachers could actively participate in MGMP activities, as one of the forums for improving their quality.
INCREASING TEACHERS' CAPABILITIES IN ONLINE LEARNING BY USING WHATSAPP DURING THE PANDEMIC AT SDN 18 BENGKALIS
Authors: Kamaruddin Kamaruddin
Published: September 2021

Organizing online learning for each educational unit and developing or determining how to provide learning to students could be done by using social media. Choosing social media in carrying out learning is necessary because social media did not recognize space and time, it made it easier to communicate with people who were far apart. Thus, it was necessary to train teachers in using WhatsApp as an alternative to learning by using action research methods or often school action research. This research involved 8 teachers at SDN 18 Bengkalis. The results of the study found that the teachers’ understanding in online learning in Cycle I was 51.13 with sufficient category. After making improvements and seeing reflections from learning, it was continued with cycle II with the results obtained an average of 73.13 with good category while the teacher's ability in learning in cycle I got sufficient category. In cycle II, out of 8 teachers, 2 teachers got very good category and 6 people got good category. In the learning carried out by the teacher using WhatsApp, there was an increase compared to cycle I. In cycle II, the teachers were already able to use WhatsApp in explaining, providing guidance, and also providing tasks that would be done by the teacher.

This study aimed to improve the students’ learning outcomes at fourth grade of SDN 010 Bagan Punak, Kecamatan Bangko, through a gadget-based internet use approach. The subjects of this study consisted of 20 students. This research was classroom action research with the aim of improving the learning outcomes and learning activities. The results of the research found that the initial data on the average score of students’ learning outcomes was only 60, meaning that it had not yet reached the completeness of the learning outcomes. Then, after learning to use the gadget-based internet with zoom media from cycle I to cycle II, students’ learning outcomes increased from the beginning of learning when using gadget-based internet in learning Bahasa Indonesia and continued to increase in each cycle. This was evidence of the success of using internet in improving student learning outcomes. In the first cycle, there was a good increase in which the average value of students’ learning outcomes as a whole was 74.6compared to the initial data which was only 60. The number of students with complete learning outcomes were 15 of the 20 students who took the learning outcomes test. it indicated around 75% of the fourth grade students at SDN 010 Bagan Punak, Kecamatan Bangko Then, it was proceeded to the second cycle in which the average of students’ learning outcomes also experienced a good increase. The students’ learning outcomes in the second cycle was 81.8 meaning that has achieved good completeness. There were about 18 students from 20 students who took the learning outcomes test completed the test, meaning that around 90% of fourth grade students at SDN 010 Bagan Punak, Kecamatan Bangko.
Climate change impacts and adaptation strategies for pasture-based industries: Australian perspective
Authors: Cullen Brendan , Harrison Matthew , Mayberry Dianne , Cobon David , Davison Thomas , Eckard Richard
Published: September 2021

In recent decades Australia has experienced warmer temperatures and, in southern Australia declining rainfall, and climate change projections indicate that these trends are likely to continue.  In southern Australia pasture growth patterns have changed with increased winter production but a contraction of the spring growing season and increased inter-annual variability of production.  A range of options have been investigated to adapt farm businesses to the changing climate including feedbase, livestock management and diversification.  The challenge for adaptation research is to better understand impacts and adaptation options for increases in extreme climate events, such as heatwaves, drought and intense rainfall events.
Soil structure: its importance to resilient pastures in New Zealand (review)
Authors: Houlbrooke David , Drewry John , Hu Wei , Laurenson Seth , Carrick Sam
Published: September 2021

Soil structure is critical to soil quality due to its influence on many soil processes and functions, including water storage and transport, the oxygen supply, the emission of greenhouse gases, and biological processes such as carbon and nitrogen mineralisation, nitrification and denitrification. These soil functions underpin key ecosystem services such as pasture production, nutrient cycling and mitigation of contaminant losses to receiving waters. The paper discusses key soil physical indicators relevant to pasture performance and the environment, including soil porosity, bulk density and hydraulic conductivity. In regions with robust programs for monitoring soil quality, e.g., Waikato, Canterbury, Auckland, Marlborough and Wellington, soil compaction is found to be widespread under pastoral land-use. The specific consequences of degraded soil quality on pasture production and financial implications remain unclear, at farm, regional and national levels. The range of impacts of soil structural damage on pasture yield, persistence, farm system response, and management practices that minimise or repair damage are presented. Knowledge gaps and further research needs are also summarised.
Osmanlı Aydınlarından Ali Kemal'in Türk Gazetesi ve Gazetenin Yayın Anlayışına Dair Bir Değerlendirme
Authors: MEZİLİ Önder
Published: September 2021

Türk Gazetesi 1903-1907 yılları arasında Mısır’ın Kahire şehrinde haftalık olarak yayınlanan siyasi, ilmi ve edebi bir gazetedir. Gazeteyi yayınlayan Osmanlı aydını Ali Kemal, 1900-1908 yılları arasında Mısır’da ikamet eder. Mısır’da rahat bir hayat yaşayan Ali Kemal gazetecilik yönünden verimli bir dönemde 1903-1907 yılları arasında Türk Gazetesi’ni yayınladı. Türk Gazetesi o dönemde Osmanlı Devleti ile ilgili siyasi gelişmelerin anlaşılması bakımından önemlidir. Ayrıca birtakım aydın ve yazarlar görüşlerini bu gazete aracılığıyla halka duyuruyorlardı. Örneğin Yusuf Akçura “Üç Tarz-ı Siyaset” adlı uzun makaleler dizisini Türk Gazetesi’nin 24-34. sayıları arasında yayınlamıştı. Ali Kemal de yayınladığı Türk Gazetesi’nde “Üç Tarz-ı Siyaset” adlı makaleye cevap olarak kendi görüşlerini dile getirdiği “Cevabımız” adlı makaleyi yayınladı. Kahire’de yayınlanan Türk Gazetesi’nde Ali Bey Hüseyinzade de Türk birliği hakkındaki fikirlerini dile getiriyordu. Türk Gazetesi incelendiğinde Osmanlı Devleti ile ilgili birçok önemli gelişmenin, gazeteyi yayınlayanlar tarafından takip edildiği görülmektedir.
INTERVENTION TO SUPPORT PEOPLE IN THEIR SELF-DEVELOPMENT PROCESS: A LITERATURE REVIEW
Authors: KIRSCHENBOIM Ofra
Published: September 2021

Nowadays, we see people who have difficulty in speaking about themselves. They found it easier to talk about others and to blame and attack them. This leads to negative energies, lack of confidence and unhappiness. Pressure, stress or anxiety can be the trigger for personal growth and development. In recent years, an attempt has been made to combine research into personality, research on mutual social action, and research into society. The need for critical self-awareness and for active, selective learning, are the factors behind the desire to combine these research areas. There are approaches that claim that interaction between individuals is the social basis. This is a micro paradigm, which states that the individual has an influence on the society. Following the literature, this paper aims to understand the self-development process, as an argument for developing a method for personal and emotional growth. Thus, the model will be developed to help people deal with crises and difficulties caused by external factors, beyond the control of the patient.
