Authors: Rahardja Untung , Sunarya Po Abas , Aini Qurotul , Dewi Shylvia Ratna
Published: October 2019

ABSTRACTDalam memasuki era disruptif 4.0 penyampaian informasi yang cepat dan akurat tentunya sangat dibutuhkan, salah satu diantaranya adalah pada bidang keuangan dan akuntansi karena mengandung informasi berupa tagihan pembayaran dan laporan keuangan guna pengambilan sebuah keputusan. Namun pada beberapa Perguruan Tinggi teridentifikasi 2 (dua) permasalahan yaitu penyebaran tagihan dilakukan secara konvensional sehingga informasi yang diterima tidak akurat dan real time serta mahasiswa melakukan pembayaran dengan cara menukar resi pembayaran dengan sebuah kwitansi. Sehingga kedua hal tersebut dapat mengakibatkan data dan laporan yang berserakan serta tidak efisien dalam segi waktu dan biaya. Dalam mencegah kedua permasalahan tersebut dibutuhkan sebuah cloud accounting guna menyebarkan tagihan dan melakukan pembayaran dapat dilakukan secara online. Jurnal.id merupakan salah satu cloud accounting dimana memiliki fitur Jurnal Payment yang memungkinkan pihak kasir dapat dengan mudah mengirim tagihan pembayaran melalui E-mail dan mahasiswa melunasi tagihan secara online. Adapun pemecahan masalah guna menyelesaikan permasalahan ini yaitu digunakan metode analisis SWOT dan 8 (delapan) studi pustaka yang dilakukan pada penelitian ini. Diharapkan dengan adanya Jurnal Payment dapat memudahkan dalam proses transaksi pembayaran guna menghasilkan data yang akurat dan real time. Sehingga dapat memudahkan dua belah pihak yaitu pihak kasir dalam proses penyebaran tagihan dan penginputan receive payment karena sudah tersinkronisasi secara otomatis serta pihak mahasiswa dalam melunasi pembayaran tagihan secara online dan keuangan menjadi lebih cashless, efektif dan efisien.

PERANAN REPRESENTASI BERBANTUAN SOFTWARE MAPLE PADA PEMBELAJARAN MATA KULIAH KALKULUS
Authors: Panjaitan Arie Candra
Published: October 2019

Abstract. Computers are essential tools for teaching, learning, and doing mathematics. Computers can visualize or represent mathematical ideas, organize and analyze data, and calculate effectively and accurately. Computers can help students conduct investigations through representations in various fields of mathematics such as geometry, calculus, statistics, algebra, measurements, and numbers. This paper discusses the role of Maple assisted representation in calculus learning. Representation is very supportive in increasing students' understanding of mathematical relations and concepts. There are three main functions of representation, namely complementing, constraining, and constructing. Complementing function is to complete the process and complete the information. The constraining function is to help students experience difficulties in a representation. The constructing function is to support constructing a deeper understanding of a concept. Students can get a deeper understanding if difficulties with only one representation. Maple software is a facility that is very supportive in making representations in learning mathematics as in calculus learning. By using Maple we can do numerical and symbolic calculations and perform graphical representations well. Maple can also effectively determine limits, derivatives, integrals, and a series of other functions and capabilities. With this Maple software capability, we can use it to improve students' understanding of calculus courses.Keywords: Representation, Computers, Maple, Calculus

Se valida un modelo de programación no lineal con datos de 2015 para evaluar la eficiencia del mercado de carne de cerdo en México mediante condiciones de optimización de Kuhn-Tucker. Se utilizaron ocho regiones productoras-consumidoras y dos puntos de internación de importaciones: Noroeste, Norte, Noreste, Centro-Oeste, Centro-Este, Sur, Oriente, Península. El modelo subestimó la producción nacional en 0.4% y sobreestimó el consumo en 2.5% con un valor social neto de 3 789.9 MMDP. La optimización dedujo producción y consumo positivos, así como margen de comercialización superior al costo de transporte, activándose rutas óptimas de distribución. El ajuste entre lo observado y el modelo fue menor a la unidad. Las condiciones de Kuhn-Tucker aplicadas al modelo de optimización permitieron demostrar la eficiencia del mercado porcino.

Published: October 2019

In this study, the irrigation

performance of Atabey Irrigation Scheme was assessed by making use of Remote

Sensing (RS) and the Geographic Information System (GIS). For this purpose, the

crop pattern maps of the scheme were generated by the help of the supervised

classification method with the RapidEye satellite data of 2012 concerning the

study area by employing the RS techniques, whereas the canal maps of the scheme

were generated by the help of the techniques of the Geographic Information

System. By the help of these data, the monthly water supply ratios – one of the

performance indicators – were computed. A total of 24 crop classes, 10 of which

were in the irrigated area corresponding to about one-third (5,239.75 ha;

33.72%) of the total area but the remaining 14 of which were in the

non-irrigated (rainfed agriculture) area corresponding to about two-thirds

(10,299.74 ha; 66.28%) of the scheme area, were determined as a result of the

crop pattern classification. The total irrigation water requirement for Atabey

irrigation scheme was calculated as 42,618 m3 minimum and 5,647,246

m3 at the maximum between April and October. The Relative Water

Supply (RWS) in the months concerned ranged from 28.16 to 2.39 and the average

in 2012 was calculated as 3.25. The assessment, collection, operating and

maintenance expenses of the scheme and, by the help of these data, its fee

collection and financial efficiency ratios were calculated. The fee collection

ratio was found as 88.12% and the financial efficiency ratio as 1.42 at the

Published: October 2019

This study was conducted to

examine the effect of 4 different quality criteria (chick weight, toe length,

shank length and chick length) on live weight, feed consumption, feed

conversion ratio and mortality in broiler chicks at the end of the fattening

period. A total of 192 male broiler chicks were used in the experiment, and two

separate groups were formed for each quality criterion. In 1 day-old chicks, a

heavy group and a light group (≥47.7 g and <47.7 g) were created for chick

weight; and a tall group and a short group were created for each of the toe

length (≥2.01 cm and <2.01 cm), shank length (≥2.9 cm and <2.9 cm) and

chick length (≥18.3 cm and <18.3 cm) criteria. At the end of the six-week

fattening period, the live weight was significantly higher in the heavy group

compared to the light group; in the short toe group compared to the tall toe

group; and in the short chick length group compared to the tall chick length

group (P<0.01 and P<0.01). In terms of feed consumption, more feed was

consumed in the heavy group compared to the light group; in the short shank

group compared to the tall shank group; and in the short chick length group

compared to the tall chick length group (P<0.01). The feed conversion ratios

were influenced by the quality criteria, and the feed efficiency was better in

the heavy group compared to the light group; in the short toe group compared to

the tall toe group; and in the short chick length group compared to the tall

chick length group. The mortality of the experimental groups showed significant

differences in the groups other than the shank length group (P<0.05).

Published: October 2019

Características físicas da madeira, como a umidade, influenciam diretamente na qualidade da superfície, resistência ao corte e energia requerida para o processamento. Portanto, o objetivo foi conhecer a relação do gasto de energia, para realizar o corte transversal, com a umidade da madeira de nove espécies. Foram utilizados cinco corpos de prova por espécie para coleta de dados de energia específica de corte. Os corpos de prova foram processados transversalmente em serra circular de carrinho. A velocidade de avanço foi mantida constante pelo alimentador de avanço mecânico e a velocidade de corte foi fixada durante todo o processo. Assim, não exerceram fonte de variação nos dados de energia específica de corte. Posteriormente, foram calculados os valores de energia específica, considerando o volume de madeira removida, para cada espécie. Os resultados mostraram que houve relação mediana entre os dados de energia específica de corte e umidade para os cortes transversal (r=-0,462). A relação obtida entre a energia específica de corte e a umidade da madeira foi inversamente proporcional, ou seja, maiores umidades facilitam o corte da madeira. Conclui-se, que a umidade exerce de fato influência no corte, afetando diretamente no quanto a madeira vai requerer de esforço durante seu processamento mecânico.

Testing a preference inference account of classic preference reversals
Authors: Balakrishnan Harish , Srivastava Nisheeth
Published: October 2019

Different theories of decision making assume different sources of preferences for the choices we make. A recent theory has proposed that preferences are inferred from past choices in respective contexts, and that such preference inference offers a rational basis for the origin of classic preference reversals given certain sequences of observations. In this paper, we empirically test this theory for some of the classic preference reversals - the attraction effect and the compromise effect, through longitudinal preferential choice experiments. In this paradigm, participants provide their preferences for different choices occurring in different contexts throughout the experiment. Results indicate evidence in favour of a considerable attraction effect but are mixed for a compromise effect. We briefly discuss the theoretical implications of our findings and possible directions for future work.

When faced with uncertainty, human observers maximize performance by effectively integrating sensory information with learned task-relevant regularities. Does this behavior similarly occur in social, intergroup settings? Here, by providing participants with repeated exposure to a probabilistic decision-making task involving social information, we characterized their ability to learn task-relevant regularities and explored how social information interacted with learning over time. In particular, we examined how a behavior typically attributed to implicit intergroup bias––taking group membership into account when irrelevant or inappropriate––might be influenced by learning mechanisms that promote efficacy in the face of uncertainty. Across two experiments we show that observers learned and utilized task-relevant regularities to inform their decisions and maximize rewards. Notably, social information was utilized only when doing so conferred reward gains. Furthermore, learning about the utility of social information had a long-term influence on observers’ ability to subsequently learn and utilize other sources of information. Taken together, our findings highlight the powerful influence of learning in intergroup contexts: human observers are sensitive to–and quickly learn–the task-relevance of social information, and are able to use this learned knowledge to flexibly reweight available sources of information.

The aim of this work was to study the effect of the interaction between tools and workpiece on the plastic behavior and microstructural evolution of a carbon steel during hot deformation of a cylinder with diameter of 600 mm and height of 1 000 mm. The metallurgical processing was simulated applying the finite elements method. Temperature, deformation and strain rate gradients, recrystallized volume fraction, and grain size distribution were determined using this technique. The data obtained shown that the level of friction and the heat transfer between tools and material have strong influence on the deformation and microstructure gradients, creating large grain size heterogeneities.

It was shown that new high-manganese austenitic steels can be used as an alternative to conventional Ni–Cr austenitic steels especially in vacuum vessels. In this study, a nickel-free austenitic steel with chemical composition of 24 wt.% Mn, 10 wt.% Cr, 0.13 wt.% C and trace elements of Si, Ti, V, W, and Al was hot-rolled at 950 and 1100 °C to different strains. Microscopic observations, X-ray diffraction, tensile, impact and microhardness tests were performed to characterize the microstructural aspects and mechanical properties. A small amount of chromium carbide was found on the grain boundaries of this fully austenitic steel. The results showed that the microstructure and mechanical properties of hot rolled manganese austenitic steel are affected by the dynamic recrystallization and twinning phenomena. Also, by changing the grain morphology from equiaxed to elongated, strength and hardness increased, and the impact toughness and ductility were reduced.

O Brasil consome 20% de todo o agrotóxico produzido no mundo. Somente até o mês de julho de 2019, 290 novas substâncias agrotóxicas foram liberadas pelo atual governo brasileiro. Conforme dados do Greenpeace, dessas novas substâncias, 41% são consideradas extremamente tóxicas, enquanto 32% são proibidas pela União Europeia. Estudos recentes demonstram que a crescente massificação de agrotóxicos no Brasil enseja prejuízos à saúde das mais diversas ordens e para os mais distintos segmentos, com destaque para as crianças, em razão da sua peculiar condição de desenvolvimento. O presente trabalho assume por objetivo principal analisar o fenômeno da massificação dos agrotóxicos no Brasil e os limites jurídicos para a responsabilização internacional pelos prejuízos severos ocasionados ao direito à saúde de crianças. Para tanto, valeu-se de pesquisa bibliográfica e documental. No primeiro tópico, apresentou-se um panorama conceitual sobre agrotóxicos no Brasil. Já no segundo, declinaram-se as normas nacionais e internacionais referentes – direta ou indiretamente - à matéria em estudo. Finalmente, no terceiro tópico, comentou-se sobre os possíveis procedimentos utilizados para a responsabilização do Estado brasileiro e das empresas transnacionais do agronegócio, no que concerne à produção, comercialização e distribuição massificadas de agrotóxicos no território nacional, dados os prejuízos ocasionados ao direito à saúde de crianças.

Background: Stress has always been with human despite all the progress in science and technology. Stressful conditions reduce concentration and lead to the lack of focus. This can increase human errors and bring about catastrophe. The aim of this study is to present a model to increase safety climate by controlling job stress among the personnel of Iran’s medical centers.

Methods:  In this study, 680 personnel of Iran’s hospitals were chosen in random. Demographic, job stress (35 questions) and safety climate (37 questions) questionnaires were filled. The data were inserted in SPSS 20 software. Descriptive statistics method and Pearson’s correlation coefficient were used to describe the data and evaluate the relation between the variables, respectively.

Results: The scores of safety climate and job stress were 3.40 and 3.21, respectively which imply that they are suitable. The overall fitness of the model was acceptable. In this model, χ2 = 6366.17, df= 2452, χ2/df = 2.596, RMSEA = 0.054 (90% CI = 0.000–0.084), NFI = 0.901, GFI=0.913, and CFI=0.856. In the regression analysis, there were positive significant relationships between job stress and safety climate, job stress and any of its components, and safety climate and any of the components.

Conclusion: Job stress is directly related to safety climate. Since in this study job stress was in a suitable level, it influenced the safety climate. If job stress is high, then it can affect safety climate in a negative way. We suggest that further studies be done regarding this subject.

Introduction: Enhancement of patient safety represents a principle objective followed by any health system, and it is necessary to consistently monitor the patient safety culture among nurses. Adopted by health service providers, the patient safety culture is described as the acceptance and maintenance of the patient safety as a common priority and value across the organization, or representation of the common patient safety-related values, beliefs, perceptions, and attitudes among the staff at centers providing health services, as expressed in their behaviors. Given the importance of this topic, the present research investigates the state of safety management in the relationship between safety management and patient safety culture in Cancer Treatment Centers, so as to study the patient safety culture among the personnel at the hospitals.

Methods: The present research plan is an applied study following a descriptive aim via a correlational methodology. Validity of the questionnaires used in this research was confirmed based on opinions of five experts, with the reliability of the results among the observers confirmed by a Cronbach’s alpha of 0.86. The statistical population included three training hospitals in the city of Kermanshah, where different departments such as management, operating rooms, nurses, and the committee of safety and incidents were investigated during 2017-2018.

Results: Based on the findings of the present research, significant direct relationships were observed between the patient safety culture and safety management variables (e.g., operating room standards assessment, the committee of safety and incidents, hospitalization wards assessment, hospital accreditation score, hospital structure, and hospital organization), and an inverse relationship was obtained between the hospital occupancy rate and the patient safety culture.

Conclusion: Determination of safety policies by the management, keeping the personnel well-trained, and continuous reports by the personnel tend to enhance the level of safety across a hospital, thereby adding to the safety culture and productivity of the hospital while reducing potential safety risks. Accordingly, in order to enhance patient safety, it is necessary to adequately invest on the assessment of the safety culture.
