Authors: Hardwiyono Sentot
Published: March 2022

The provision of road infrastructure cannot be separated with the pavement construction itself. One of the materials used is asphalt that is really related to natural resources. Using asphalt is not durable in many cases because of the oxidation process, mainly due to heating. This can lead the road (flexible pavement) to fast deformation, including cracking. Nowadays, there are many additives to improve the asphalt quality. One of them is adding rubber to the asphalt which can give more durability under high temperatures, increase its adhesion, and improve its flexibility. This study used the additives in the form of shredded rubber with the content of 20%, 21%, and 22% of the total mass of asphalt. The shredded rubber was mixed with the asphalt, and then heated at least 45 minutes before mixing it with the aggregates. The HRS WC mixture with the tire rubber was compared in term of optimum asphalt content and Marshall results. The results show that adding shredded tire rubber in HRS WC mixture can decrease the flow. This shows that the addition of shredded rubber can decrease of the sample deformation, so that the mix will not be too plastic and easily deformed under the loading. It can also increase the VIM and decrease the VFA, so that it can reduce the bleeding possibility.

Yogyakarta is a region with high traffic. It also has high population density. These matters have been predicted to cause transportation problems. HOS Cokroaminoto Street, as a road in urban city center, has the potential to have such problems. Analysis and evaluation needs to be done to maintain good performance of the road. Manual Kapasitas Jalan Indonesia 1997 is used to measure the performance of traffic which includes operational analysis and the planning of urban roads. Level of Service Criteria (LSC) is determined based on the regulation of The Ministry of Transportation KM No. 14 of 2006. Traffic data had been obtained by counting the number of vehicles for 3 days on the busy-hour. These data were presented in tabular data of the vehicle, and then the performance of the traffic was analyzed. For urban roads, form UR-1, UR-2, and UR-3 (MKJI 1997) are used. Based on the results of the performance analysis on HOS Cokroaminoto Street with MKJI 1997 method, in 2010, the degree of saturation (DS) of the road is 0.43. It means that, in LSC term, this road is in level B. It is predicted that, in 2016-2020, this road will not satisfy the eligibility standard (DS 0.75). This shows that the performance improvement of HOS Cokroaminoto Street is required. From the alternative solutions, the scenario of side friction reduction is more rational to maintain the eligibility and performance of HOS Cokroaminoto Street.

Published: March 2022

Concrete is one of the most commonly used materials for construction. Due to the increased of concrete demand, the need for alternative material to substitute natural aggregate becomes crucial. In this study HDPE plastic waste was used as artificial aggregate. HDPE was mixed with natural coarse aggregate at variation of 0%, 10%, 15% and 20%. Compressive test and split tensile tests were performed on concrete age of 28 days. The compressive strength of concrete decreased with the addition of HDPE levels. The result shows that the highest value of compressive strength was 27,88 MPa on 0% HDPE and the lowest value was 11,08 MPa on 20% HDPE mixture. The highest split tensile strength achieved by normal concrete of 2,71 MPa. Split tensile strength of concrete gradually decreased with the addition of HDPE variations. The lowest value of tensile strength was obtained from variation of 20% HDPE plastic waste that is equal to 1.72 MPa. From the analysis it can be concluded that the replacement of coarse aggregate crushed stone with HDPE plastic waste reduce split tensile strength of concrete.

The objective of the current investigation is to find out temperature distribution regimes in a horizontal pipe when condensation process is happened.  The research was conducted at Pusat Studi Ilmu Teknik Universitas Gadjah Mada. The experiment apparatus consists of an inner annulus pipe made from copper (din = 17.2 mm, do = 19 mm) with the length of 1.8 m. The outer annulus pipe is a galvanized iron pipe (din = 108.3 mm, do = 114.3 mm) with the length of 1.6 m. Thermocouples type K 36 TT OMEGA with chromel (+) and alumel (-) materials were used as temperature sensors, to detect the spread of temperature in radial or axial direction along the pipe. The measurement ranged from -50 to 260 oC, with an accuracy of 0.01 °C. A data logger of RX 40 serial (OMRON, 20 Channels) was used to read and record temperature data with the sampling rate of 5 Hz. In the experiment, the water (H2O)was heated using a boiler to generate steam which was then flowed and condensed inside the annulus pipe to form a steam-condensate two-phase flow in horizontal pipe. On the other hand, the water was used as a coolant in the outer of annulus pipe. The results indicated that the temperature distribution regimes are influenced by axial posisition.The farther distances from the inlet the lower the temperatures being recorded which indicate the increase of film condensate thickness. Such phenomena can affect slugging in the location.

Universitas Muhammadiyah Yogyakarta (UMY) is a big and high-grade educational institution. During the period of 1998-2014, UMY has produced about 20550 graduates. But, the big number of graduates is not supported by a good data storage system. Whereas those data are needed in filling up the accreditation form. For that reason, we have to build an integrated data storage system to provide graduates data as needed, that is graduate data mart. The development of graduate data mart uses SDLC Model Waterfall method. This method involves several types, there are requirement analysis, design system, implementation system, testing system, and maintenance system and those must be done sequentially. If there is an error, the process must be repeated from the beginning to fix the error. Development of graduate data mart uses Operational Data Store (ODS) and Dimensional Data Store (DDS) architecture. Those architectures are selected because they support transactional level. By using those architectures, graduate data mart is capable to display the data of graduates on the academic year, GPA, educational years, and the status of the student transfers. As the result, those data are able to help the management of university in filling up the accreditation form.

Esse artigo apresenta uma reflexão sobre as questões de gênero e educação no Estado do Amazonas. Trata-se de um recorte de pesquisa em andamento desenvolvida no Programa de Pós-Graduação em Ensino de Ciências e Humanidades (PPGECH) no âmbito da Universidade Federal do Amazonas – UFAM, Unidade de Humaitá - IEAA. Neste recorte busca-se refletir sobre a tratativa das questões relacionadas ao gênero na educação pública do Estado do Amazonas, considerando o questionamento que impulsiona a pesquisa: De que forma o Estado do Amazonas tem lidado com as questões de gênero no cenário educacional? Buscou-se, então, levantar pesquisas recentes desenvolvidas sobre a temática no contexto amazonense, discutir o que dizem os documentos oficiais regulatórios da educação no Amazonas e descrever a atuação das secretarias Seduc/Am e Semed/Manaus em torno da temática. O amparo teórico-metodológico tem como base a metodologia pós-crítica em Educação, a partir de autores que transitam entre os campos de prefixos “Pós” trazidos por Meyer e Paraíso (2012), ancorados nos estudos culturais, de gênero e estudos feministas. A produção de dados se deu a partir do estudo bibliográfico e documental. A análise dos resultados, realizada a partir de uma abordagem qualitativa, sugere que as questões de gênero possuem um espaço muito discreto no cenário educacional amazonense, mas que desponta como uma pauta que pode e deve ser ampliada.
Enhancement of the O2 Sensitivity: ZnO, CuO, and ZnO/CuO Hybrid Additives' Effect on Meso-Tetraphenylporphyrin Dye
Authors: ZEYREK ONGUN Merve
Published: March 2022

Semiconductor metal oxide materials have attracted great interest in gas sensors due to their high sensitivity to many target gases. In this study, an oxygen-sensitive optical chemical sensor was prepared in thin-film form by immobilizing meso-tetraphenylporphyrin (H2TPP) in silicon matrix in the presence of ZnO, CuO and ZnO/CuO hybrid nanoparticles as additives. Characterization of synthesized metal oxide powders was performed using XPS, XRD, SEM, and PL spectroscopy. Emission and decay time measurements of H2TPP-based materials were investigated between the concentration range of 0% and 100% [O2] in thin-film forms. The intensity-based signal drops of the additive-free form of porphyrin dye toward oxygen were calculated as 70%. Whereas, the oxygen sensitivities of H2TPP-based sensor slides were measured as 80%, 75%, and 88% in the presence of ZnO, CuO, and ZnO/CuO hybrid particles, respectively. The usage of porphyrin dye with ZnO/CuO hybrid additive provided higher oxygen sensitivity, larger linear response range, higher Stern-Volmer constant (KSV) value and faster response time compared to the undoped form, ZnO and CuO additive-doped forms of H2TPP. The response and the recovery times of the porphyrin-based sensing slide along with ZnO/CuO hybrid particles have been measured as 10 and 20 s. These results make the H2TPP along with the metal oxide additives promising candidates as oxygen probes.

Authors: DEMİREL Maruf Hurşit , AYDOĞMUŞ Ercan
Published: March 2022

In this research, new composite materials were improved by reinforcing the environment-polluting waste polyurethane (WPU) to unsaturated polyester (UP). Polyester composites were produced with WPU, UP, methyl ethyl ketone peroxide (MEKP), and cobalt octoate (Co. Oc.). The effect of WPU on the changes in density, Shore D hardness, thermal conductivity coefficient, thermal stability, and porosity of the obtained composites were investigated. According to the findings, as WPU ratio increased in the composite, both the thermal conductivity coefficient and the density of the composite decreased. Shore D hardness was been found to decrease as the rate of WPU in polyester composites raised. The use of optimum WPU ratios (7 wt.%) in composite production improved some thermo-physical properties of polyester composite. The high use of WPU negatively affected both the surface morphology and thermal stability of the polyester composite. In addition, the parameters affecting the production of polyester composites were optimized according to response surface methodology (RSM).

Amaç: Bu çalışmada kompozit üretim işinde kullanılan pek çok kimyasalın neden olduğu Mesleksel Astım (MA) sonucu çalışanların hem klinik hem tanı sonrası sosyal durum, işyeri koşulları ve tanıya bağlı karşılaştıkları durumları değerlendirmeyi amaçladık.

Gereç ve Yöntemler: Çalışma kesitsel bir çalışmadır. Ağustos 2018- Ağustos 2021 tarihleri arasında Meslek hastalıkları polikliniğine yönlendirilen bu sektörde çalışan, MA tanısı alan olgular değerlendirilmiştir. Olguların maruz kalım öyküleri, mesleki astım risk faktörleri yanı sıra meslek hastalıkları durum bildirir rapor sonrası işe devam etme ve klinik durumları değerlendirilmiştir.

Bulgular: İzmir ve çevresinde bulunan fabrikalardan gelen toplamda 126 olgu değerlendiril-di. Son tanı olarak 45 olguya (%35,7) astım tanısı koyulurken bunlardan 33 olguya (%26,1) PEF izlemi yapılarak mesleki nedensellik ilişkisi kuruldu. Bu olgulardan 31’i (%93,9) erkek, yaş ortalaması 31,18± 5,5 (min/maks 23-46) idi. Maruz kalım ile yakınmaların ortaya çıkması arasındaki latent süre ortancası 36 aydı. Çalışanların tanı sonrası Meslek Hastalığı (MH) kaydı veya SGK’ya MH bildirimi konularında bilgi sahibi olmadıkları görüldü. Olguların çoğunluğu (30 olgu, %93,7) işyerinde sağlığı tehdit eden risk varlığı olduğunu, en sık riskin toz ve kimyasal riskler olarak bildirdi. Olgulardan 19 (%57,5)’u MH raporunu aldıktan sonra işyerinden ayrılmış, 14 (%42,5) olgu ise rapor sonrası aynı işyerinde çalışmaya devam ediyordu. Bunlardan 8 (%24,2)’ine bölüm değişikliği yapılmıştı. 25 olguya (%75,7) işten ayrılması için baskı yapılmıştı. İşten ayrılan olgulardan sadece 1 tanesi kendi ayrılış yapmıştı diğer 18 (%54,5) olgunun sözleşmesi işveren tarafından feshedilmişti. İşten ayrıldıktan sonra bütün olguların yakınmaları gerilemiş ve ilaç kullanım ihtiyacı azalmıştı.

Sonuç: Kompozit materyal üretim sürecinde çalışanların sağlık etkilerini ortaya koymuş, MH tanısı sonrası işyerinde karşılaştıkları etkileri değerlendirilmiştir. İşyerinde MH izlemi ve yönetimi açısından elde edilen sonuçların çalışanların haklarını korumak bakımından halen oldukça yetersiz olduğu görülmüştür.

Anastomoz kaçağına etki eden başlıca faktörün ameliyat zamanlaması olduğu ve acil şartlarda ameliyat edilen hastalarda anastomoz kaçağı riskinin anlamlı şekilde arttığı tespit edildi. İleri yaş ve düşük albümin düzeyi anastomoz kaçağı ve mortalite üzerine etki eden diğer risk faktörleri olarak tespit edildi.

Sonuç: Bu çalışma sonucunda ameliyat zamanlaması, hasta yaşı ve düşük albümin düzeyi sağ hemikolektomi sonrasında anastomoz kaçağına etki eden faktörler olarak tespit edilmiştir. Acil ameliyat gerektiren ileri yaştaki, beslenme bozukluğu olan hastalarda sağ hemikolektomi sonrası anastomoz yapılması yerine diversiyonun tercih edilmesi uygun bir yaklaşım olacaktır.
Normalisation of Precariousness? Biographical Experiences of Young Workers in the Flexible Forms of Employment in Poland
Authors: Mrozowicki Adam
Published: March 2022

This article explores interpretive practices and life strategies related to the flexibilisation of employment in Poland. The socio-economic background for workers’ biographical experiences and coping patterns can be defined in terms of a shift from the socialist type of Fordism to the capitalist, neoliberal, flexible labour regime. In 2015, Poland remained the leader in the EU in terms of the share of employees with temporary contracts in total employment. Yet, despite the expansion of precarious employment, the Polish workers were, until recently, not too prone to protest. This paper explains this apparent paradox by analysing the meanings given to the changing nature of employment by workers themselves in the context of their overall biographical experiences. The empirical basis are 24 biographical narrative interviews collected within a mini-research project on non-unionised young (18-29) workers in services in the city of Wrocław, in South-Western Poland (in 2013). The analysis documents some level of “normalisation” of unstable employment among young precarious employees for whom it became an important aspect of their “taken-for-granted” assumptions related to their occupational careers. Simultaneously, the research demonstrates the biographical and social limits of “normalisation of precariousness” and suggests that the “disenchantment” with flexibility can (in some cases) contribute to greater support for various collective counter-movements (Karl Polanyi). In the article, both the normalisation and disenchantment with market flexibility are discussed with the reference to selected biographical cases.

Anak usia dini adalah anak yang rentang usianya 0-6 tahun, masa ini adalah waktu yang pas untuk memberikan stimulus yang baik kepada anak baik untuk kecerdasannya, perkembangannya maupun moralnya. Moral sangat penting diberikan kepada anak sebab moral adalah yang menentukan baik dan buruknya seseorang. Dalam meningkatkan moral tentunya guru menggunakan metode salah satunya dengan metode keteladanan yakni pemberian contoh langsung kepada anak.

Pada penelitian ini menggunakan kualitatif deskriptif, adapun sumber datanya diperoleh dengan melalui proses wawancara, observasi dan pengambilan dokumentasi. Informannya yakni guru sebagai figur keteladanan. Sedangkan keabsahan data di cek dengan melakukan perpanjangan keikiutsertaan.

Adapun yang didapat peneliti dari hasil penelitian ini menunjukkan bahwa : Pertama, implementasi metode keteladanan dalam meningkatkan moral ini dilakukan dengan cara mencontohkan hal-hal baik yakni dengan sholat berjamaah, berdoa, memburang sampah pada tempatnya, bersikap lemah lembut kepada sesama. Kedua, hasil dari penerapan metode keteladanan itu membuat anak dengan sendirinya melakukan tanpa disuruh sekalipun, contoh sudah bisa berwudhu’ sendiri, membuang sampah pada tempatnya sehingga sekolah itu sangat bersih, dan bertutur sapa dengan baik, sholat berjamaah bersama.

In the present investigation, the parents (P1 and P2), F1,’s, F2’s and BC1F1’s progenies of four selected hybrids involving four cytoplasmic genetic male sterile lines based on Cajanus scarabaeoides (A2) cytoplasm and four restorers from diverse source were evaluated to determine the inheritance of fertility restoration in pigeonpea [Cajanus cajan (L.) Millsp)] hybrids. Among these restorers, three restorers viz. BDNHR 1, BDNHR 21-2 and BDNHR 22-1-2 were identified and developed from segregating materials of interspecific cross involving C. scarabaeoides, however one restorer viz. BDNHR 60-2 from interspecific cross involving C. albicans wild species. The results revealed that the hybrids viz. BDN 2004-1A x BDNHR 1, BDN 2004-4Ax BDNHR22-1-2 and BSMR 736A x BDNHR 21-2 showed the monogenic dominant gene action (3:1) with single fertility restoring gene. However, only one hybrid viz. BDN 2004-2A x BDNHR 60-2 showed digenic duplicate gene action with complete dominance for fertility restoration in Pigeonpea hybrids. The information generated on genetics of fertility restoration will help in knowing the selection of breeding methods and further transfer of fertility restorer genes in to elite backgrounds.

Biofertilizers are micro-organisms that originated either from root nodule or rhizospheric soil and enrich the soil by enhancing the availability of nutrients to crop also reduce the application of chemical fertilizers, ensuring environmental safety. Nitrogen and phosphorus are the major plant nutrients, which are referred to as the master key element in crop production. Some of the beneficial microbes used in biofertilizers are N2 –fixing bacteria, phosphate-solubilizing microbes which are able to fix atmospheric nitrogen or solubilize phosphorus in the soil. In the present study, fifteen Azotobacter and five phosphate solubilizing fungal (PSF) isolates were isolated from chilli rhizosphere of Kolhapur District. All isolates were identified on the basis of morphological, cultural, microscopic features and different biochemical tests. The results of yield parameters revealed that the treatment, 100% RDF + commercial Azotobacter + commercial PSF, showed the highest number of flowers (55.67 / plant), number of fruits (41.67 / plant), length of fruit (9.60 cm) and green Chilli yield (25.23 t/ ha) was on par with treatment, 100% RDF + Efficient Azotobacter + Efficient PSF i.e. number of flowers (52.87 / plant), number of fruits (39.00 / plant), length of fruit (8.80 cm) and green chilli yield (21.69 t/ ha). Whereas, highest dry matter weight (102.21 g), available N (178.75 Kg/ha), P (22.03 Kg/ha) and K (187.22 Kg/ha) was showed by treatment, 100% RDF + commercial Azotobacter + commercial PSF which was on par with treatment, 100% RDF + Efficient Azotobacter + Efficient PSF i.e. dry matter weight (98.00 g), available N (176.66 Kg/ha), P (21.59 Kg/ha) and K (186.40 Kg/ha) in soil after harvest.

Four marine microalgal strains viz. Pavlova sp. ABT 102, Chromulina sp. ABT 103, Thalassiosira sp. AMS 5 and Chlorella sp. AMS 6 were tested for their biomass and lipid productivities through bench-scale studies to assess their potential for production of value added products. Among the four different marine microalgal strains Pavlova sp. ABT 102 isolate showed maximum volumetric biomass productivity of 0.048 g L-1d-1 followed by Chlorella sp. AMS 6 (0.035 g L-1d-1), Thalassiosira sp. AMS 5 (0.021 g L-1d-1) and Chromulina sp. ABT 103 (0.019 g L-1d-1). The highest volumetric lipid productivity was recorded by Chromulina sp. ABT 103 (11.12 mg L-1d-1) followed by Pavlova sp. ABT 102 (10.65 mg L-1d-1), Thalassiosira sp. AMS 5 (8.77 mg L-1d-1) and Chlorella sp. AMS 6 (7.73 mg L-1d-1). Among four algal strains, Chlorella sp. AMS 6 could effectively utilise sodium bicarbonate as an external inorganic carbon source in the growth medium. It was found that the addition of inorganic carbon source (sodium bicarbonate) in the algal strain AMS 6 Chlorella sp. enhanced biomass and lipid productivity by 6.5 and 7.6%, respectively. This strain when grown in 1-m2 open raceway pond with and without CO2 supplementation showed volumetric and areal biomass productivities of 0.046 g L-1 d-1 and 6.9 g m-2 d-1 in CO2 supplemented treatment and 0.032 g L-1 d-1 and 4.8 g m-2 d-1 for control, respectively. Total lipid content of Chlorella sp. AMS 6 with and without CO2 supplementation was 28-30% and did not show significant variation. The present study showed the potential of microalga Chlorella sp. AMS 6 to be utilised for biomass and lipid production for commercial applications.

Field experiment was carried out during 2020-2021 to study the effect of amino acids and silicon on flowering, fruit characters and yield of pomegranate cv. Phule Bhagwa Super in a randomized block design with seven treatments which were replicated three times. The treatments were Potassium silicate 0.5% (T1), Potassium silicate 1.0 % (T2), Amino acids 150 ppm (T3), Amino acids 200ppm (T4), Amino acids 250 ppm (T5), Water spray (T6), Absolute control (T7). Foliar sprays of each treatment except T7 were applied twice. The first spray was taken one month before water holding for inducing hasta bahar (hasta flowering) and second spray was taken15 days after initial growth, but before flowering. The results revealed that all the parameters studied were significantly influenced due to foliar spraying of different concentrations of potassium silicate and amino acids. The treatment T5 (amino acids 250 ppm) recorded maximum number of hermaphrodite flowers/ tree (147), sex ratio (33.3), fruit set(67.8%), number of fruit per tree (99.7), fruit weight (g) and yield per tree (35.3 kg) whereas the treatment T4 (amino acids 200 ppm) recorded highest fruit weight (302.8g). The results suggested that spraying amino acids is more effective as compared to silicon as it produced more number of hermaphrodite flower, fruit set, fruit weight number of fruits per plant and yield per plant.
