Authors: Bahrin Bahrin
Published: February 2021

Air merupakan kebutuhan utama bagi proses kehidupan di bumi, sehingga tidak ada kehidupan seandainya di bumi tidak ada air. Namun demikian, air dapat menjadi malapetaka bilamana tidak tersedia dalam kondisi yang benar, baik kualitas maupun kuantitasnya. Air yang relatif bersih sangat didambakan oleh manusia, baik untuk keperluan hidup sehari-hari, untuk keperluan industri, keperluan pertanian dan lain sebagainya. Sehingga secara kualitas, sumber daya air telah mengalami penurunan. Demikian pula secara kuantitas, yang sudah tidak mampu memenuhi kebutuhan yang terus meningkat. Oleh sebab itu dibutuhkan seorang pakar yang dapat menangani masalah kualitas air. Karena sistem ini adalah milik instansi maka dari itu sistem pakar ini merupakan sistem pakar yang diperuntukkan untuk masyarakat Pohuwato sebagai tempat kami melakukan penelitian. Hasil pengujian yang dilakukan dengan metode white box testing dan bases path testing yang menghasilkan nilai V(G) = CC, dimana V(G) = 4 dan CC = 4, sehingga didapat bahwa logika flowchart perhitungan vektor S dan Vektor V serta perankingan adalah benar dan berdasarkan pengujian black box yang meliputi uji input proses dan output dengan mengacu pada rancangan perangkat lunak yang sudah dibuat telah terpenuhi dengan hasil sesuai dengan rancangan.

Proses penerimaan sumber daya manusia memerlukan cara yang professional dan akurat agar menghasilkan sumber daya manusia yang dapat mendukung mutu dan kesuksesan sebuah organisasi. Dalam proses perjalanannya, sumber daya manusia menjadi sebuah investasi bagi sebuah organisasi untuk dapat tumbuh dan berkembang sesuai dengan visi dan misi organisasi. Oleh karenanya obyektivitas sangat diperlukan untuk dapat menunjang setiap keputusan agar mendapatkan sumber daya manusia yang baik untuk jangka waktu yang panjang. Namun, hal ini sangatlah kontradiktif dengan yang diimplementasi di lapangan. Seringnya penilaian yang berdasarkan subyektivitas dan nepotisme merupakan salah satu contoh dari kegagalan dalam pengambilan keputusan dalam proses penerimaan. Bila dibiarkan dalam jangka yang panjang hal tersebut dapat mempengaruhi kinerja sebuah organisasi sehingga berakibat pada gagalnya organisasi dalam mencapai tujuan. Dalam upaya mencapai tujuannya itu, maka Hotel Irene memerlukan sebuah Sistem Pendukung Keputusan penerimaan karyawan melalui sistem komputerisasi berbasis web dengan menggunakan bahasa pemrograman PHP. Metode yang diajukan untuk merancang sistem pendukung keputusan ini adalah SAW.

This research is intended to know the impact of PBBP2 acceptance to the regional tax. This research uses primary data from the results of interview with the collecting division of PBBP2, meanwhile the secondary data are report target and the realization of PBBP2 acceptance and regional tax of BPPRD of Muba 2014 to 2018. Technique of data analysis used is quantitative descriptive analysis technique by calculating target ratio and realization of PBBP2 acceptance, regional tax and graphic data presentation. The result of this research shows that the performance of BPPRD Muba in collecting regional taxes, especially PBBP2 is not optimum since the decision of PBBP2 acceptance target is not based on SPOP and is not appropriate with the tax potentiality, so PBBP2 target is not accurate. This gives the impact of low acceptance of regional tax from PBBP2 22.44%, so the regional tax acceptance from PBBP2 is relatively small, the average is only 15.07%. Thus, the realization of PBBP2 is very low during 2014 to 2018 only 64%. This is caused by the system and procedures of tax objects data collection are not accurate, the payment system is not online and just through the regional bank, lack of socialization and low awareness of tax obedience.

Industrial waste pollution from the upstream of the Bengawan Solo river, makes the river's quality unfit for various purposes. Water filtering needs to be done first to improve its quality. One of them is the absorption process. One of the adsorbents that have good prospects is rice husk waste because of its ability to bind the adsorbate components. Study related to the effectiveness of rice husk charcoal as a water filter material need to be carried out before it can be used as a water filter material. Making appropriate filter technology needs to be done to apply it. The results of the analysis show that the filter can improve the physical parameters of water, namely reducing the residue by 25% on average. Meanwhile, from inorganic chemical parameters, only DO (Dissolved Oxygen) elements have decreased in quality standards. The organic chemical parameters, namely the phenol content are relatively constant, this indicates that rice husk charcoal is not effective in binding phenols. Based on Government Regulation No. 82 of 2001, the filtered water is classified as Class I. However, in its use, other parameters that have not been studied should be studied, namely microbiology, other organic chemistry, radioactivity, etc.The technological capacity needs to be increased by the use of a larger body and or a reduction in the thickness of the filter layer. Meanwhile, the manufacture of rice husk charcoal should use controlled combustion mechanisms and or husk charcoal activation with the chemical Na OH to strengthen the properties of the husk charcoal adsorbent against harmful chemical compounds.

Effect of chemically induced fracturing on the ice nucleation activity
of alkali feldspar
Authors: Kiselev Alexei , Keinert Alice , Gaedecke Tilia , Leisner Thomas , Sutter Christoph , Petrishcheva Elena , Abart Rainer
Published: February 2021

Abstract. Feldspar is an important constituent of airborne mineral dust. Some alkali feldspars exhibit particularly high ice nucleation (IN) activity. This has been related to structural similarities of the ice (10-10) prism planes and the (100) planes of alkali feldspar. Here the effect of generating surfaces with close to (100) orientation by means of chemically induced fracturing on the IN activity of alkali feldspar was investigated experimentally. Gem quality K-rich alkali feldspar was shifted towards more Na-rich compositions by cation exchange with an NaCl-KCl salt melt at 850 °C, and a system of parallel cracks with an orientation close to (100) was induced. Droplet freezing assay experiments performed on grain mounts of the cation exchanged alkali feldspars revealed an increase of the overall density of ice nucleating active sites (INAS) with respect to the untreated feldspar. In addition, annealing at 550 °C subsequent to primary cation exchange further enhanced the INAS density and lead to IN activity at exceptionally high temperatures. Although very efficient in experiment, fracturing by cation exchange is unlikely to be of relevance in the conditioning of alkali feldspars in nature. However, parting planes with similar orientation as the chemically induced cracks may be generated in lamellar microstructures resulting from the exsolution of initially homogeneous alkali feldspar, a widespread phenomenon in natural alkali feldspar known as perthite formation. Perthitic alkali feldspars indeed show the highest IN activity. We ascribe this phenomenon to the preferential exposure of crystal surfaces oriented sub-parallel to (100).

Abstract. The enormous problems caused by the scarcity of potable water and the transmission of waterborne diseases such as cholera, dracunculiasis, hepatitis, typhoid and filariasis in some parts of Nigeria have created a public health concern. Every day thousands of lives are lost due to contact with waterborne diseases. The insufficient medical resources available in developing countries are deployed towards the treatment of waterborne diseases that can easily be avoided if potable water can be made available. This study seeks to investigate the purification of four different water samples (namely water from flowing rivers, freshly dug well or groundwater, rainwater from the rooftops and heavily polluted dirty water) consumed by the people in the local community using a solar desalination method. A single basin solar still was constructed, and experimental studies were carried out to determine the influence of solar insolation and temperature variations on the yield of the distillate for both the passive and active solar stills tested. The quality of the distillate was tested by measuring the total dissolved solid (TDS) and electrical conductivity (EC) and later comparing it to the World Health Organization (WHO) standard for drinkable water. The values obtained after desalination fall within the acceptable/tolerable range for TDS and EC, in accordance with the WHO standard for drinkable water. This analysis provides an indigenous distillation method to enhance the production of drinkable water at a low cost.

Abstract. The monthly standardized precipitation evapotranspiration index (SPEI) can
be used to monitor and assess drought characteristics with 1-month or
longer drought duration. Based on data from 1961 to 2018 at 427
meteorological stations across mainland China, we developed a daily SPEI
dataset to overcome the shortcoming of the coarse temporal scale of monthly
SPEI. Our dataset not only can be used to identify the start and end dates
of drought events, but also can be used to investigate the meteorological,
agricultural, hydrological, and socioeconomic droughts with a different timescales. In the present study, the SPEI data with 3-month (about 90 d)
timescale were taken as a demonstration example to analyze spatial distribution
and temporal changes in drought conditions for mainland China. The SPEI
data with a 3-month (about 90 d) timescale showed no obvious intensifying
trends in terms of severity, duration, and frequency of drought events from
1961 to 2018. Our drought dataset serves as a unique resource with daily
resolution to a variety of research communities including meteorology,
geography, and natural hazard studies. The daily SPEI dataset developed is
free, open, and publicly available from this study. The dataset
with daily SPEI is publicly available via the figshare portal (Wang et al.,
2020c), with https://doi.org/10.6084/m9.figshare.12568280.Highlights. A multi-scale daily SPEI dataset was developed across mainland China
from 1961 to 2018.
The daily SPEI dataset can be used to identify the start and end days of the
drought event.
The developed daily SPEI dataset in this study is free, open, and

Published: February 2021

Abstract. We present the Copernicus Atmosphere Monitoring Service
TEMPOral profiles (CAMS-TEMPO), a dataset of global and European emission
temporal profiles that provides gridded monthly, daily, weekly and hourly
weight factors for atmospheric chemistry modelling. CAMS-TEMPO includes
temporal profiles for the priority air pollutants (NOx; SOx;
NMVOC, non-methane volatile organic compound; NH3; CO; PM10; and PM2.5) and the greenhouse gases
(CO2 and CH4) for each of the following anthropogenic source
categories: energy industry (power plants), residential combustion,
manufacturing industry, transport (road traffic and air traffic in airports)
and agricultural activities (fertilizer use and livestock). The profiles are
computed on a global 0.1 × 0.1∘ and regional European 0.1 × 0.05∘ grid
following the domain and sector classification descriptions of the global
and regional emission inventories developed under the CAMS programme. The
profiles account for the variability of the main emission drivers of each
sector. Statistical information linked to emission variability (e.g.
electricity production and traffic counts) at national and local levels were
collected and combined with existing meteorology-dependent
parametrizations to account for the influences of sociodemographic factors
and climatological conditions. Depending on the sector and the temporal
resolution (i.e. monthly, weekly, daily and hourly) the resulting profiles are
pollutant-dependent, year-dependent (i.e. time series from 2010 to 2017)
and/or spatially dependent (i.e. the temporal weights vary per country or
region). We provide a complete description of the data and methods used to
build the CAMS-TEMPO profiles, and whenever possible, we evaluate the
representativeness of the proxies used to compute the temporal weights
against existing observational data. We find important discrepancies when
comparing the obtained temporal weights with other currently used datasets.
The CAMS-TEMPO data product including the global (CAMS-GLOB-TEMPOv2.1,
https://doi.org/10.24380/ks45-9147, Guevara et al., 2020a) and
regional European (CAMS-REG-TEMPOv2.1, https://doi.org/10.24380/1cx4-zy68, Guevara et al., 2020b) temporal
profiles are distributed from the Emissions of atmospheric Compounds and

Published: February 2021

Abstract. The presence of bare patches within otherwise vegetated coastal marshes is sometimes considered to be a symptom of marsh dieback and the subsequent loss of important ecosystem services. Here we studied the topographical conditions determining the presence and revegetation of bare patches in three marsh sites with contrasting tidal range, sediment supply, and plant species: the Scheldt estuary (the Netherlands), Venice lagoon (Italy), and Blackwater marshes (Maryland, USA). Based on GIS (geographic information system) analyses of aerial photos and lidar imagery of high resolution (≤2×2 m pixels), we analyzed the topographic conditions under which bare patches occur, including their surface elevation, size, distance from channels, and whether they are connected or not to channels. Our results demonstrate that, for the different marsh sites, bare patches can be connected or unconnected to the channel network and that there is a positive relationship between the width of the connecting channels and the size of the bare patches, in each of the three marsh sites. Further, pixels located in bare patches connected to channels occur most frequently at the lowest elevations and farthest distance from the channels. Pixels in bare patches disconnected from channels occur most frequently at intermediate elevations and distances from channels, and vegetated marshes dominate at highest elevations and shortest distances from channels. In line with previous studies, revegetation in bare patches is observed in only one site with the highest tidal range and highest sediment availability, and it preferentially occurs from the edges of small unconnected bare patches at intermediate elevations and intermediate distances from channels. Although our study is only for three different marsh sites with large variations in local conditions, such as tidal range, sediment availability, and plant species, it suggests that similar topographic conditions determine the occurrence of bare patches. Such insights may inform decision makers on coastal marsh management on where to focus monitoring of early signatures of marsh degradation.
Current status on the need for improved accessibility to climate models code
Authors: Añel Juan A. , García-Rodríguez Michael , Rodeiro Javier
Published: February 2021

Abstract. Over the past few years, increasing attention has been focused on the need to publish computer code as an integral part of the research process. This has been reflected in improved policies on publication in scientific journals, including key related issues such as repositories and licensing. We explore the state of the art of code availability and the sharing of climate models using the Fifth Coupled Model Intercomparison Project (CMIP5) models as a test bed, and we include some particular reflections on this case. Our results show that there are many limitations in terms of access to the code for these climate models and that the climate modelling community needs to improve its code-sharing practice to comply with best practice in this regard and the most recent editorial publishing policies.

Published: February 2021

Abstract. This paper presents a novel kinematics architecture with 4 DoFs (degrees of freedom) intended to be used as a haptic interface for laparoscopic surgery. The proposed architecture is a result of an association of serial and parallel kinematics chains, with each one handling a part of the whole device DoF. The serial chain allows one to handle the translation and self-rotation and the parallel chain handles the two tilt motions, and this in a disjoint way as the natural gesture of the surgeon. The proposed hybrid-haptic device (HH device) benefits from the split DoF to ensure a good kinematic performance, large workspace, as well as gravity compensation. The kinematics study of the HH device is presented and followed by the optimal dimensional synthesis and the gravity compensation model.

Abstract. The changing climate and anthropogenic activities raise the
likelihood of damage due to compound flood hazards, triggered by the
combined occurrence of extreme precipitation and storm surge during high
tides and exacerbated by sea-level rise (SLR). Risk estimates associated
with these extreme event scenarios are expected to be significantly higher
than estimates derived from a standard evaluation of individual hazards. In
this study, we present case studies of compound flood hazards affecting
critical infrastructure (CI) in coastal Connecticut (USA). We based the
analysis on actual and synthetic (considering future climate conditions for
atmospheric forcing, sea-level rise, and forecasted hurricane tracks)
hurricane events, represented by heavy precipitation and surge combined with
tides and SLR conditions. We used the Hydrologic Engineering Center's River
Analysis System (HEC-RAS), a two-dimensional hydrodynamic model, to simulate
the combined coastal and riverine flooding of selected CI sites. We forced a
distributed hydrological model (CREST-SVAS) with weather analysis data from
the Weather Research and Forecasting (WRF) model for the synthetic events
and from the National Land Data Assimilation System (NLDAS) for the actual
events, to derive the upstream boundary condition (flood wave) of HEC-RAS.
We extracted coastal tide and surge time series for each event from the
National Oceanic and Atmospheric Administration (NOAA) to use as the
downstream boundary condition of HEC-RAS. The significant outcome of this
study represents the evaluation of changes in flood risk for the CI sites
for the various compound scenarios (under current and future climate
conditions). This approach offers an estimate of the potential impact of
compound hazards relative to the 100-year flood maps produced by the Federal
Emergency Management Agency (FEMA), which is vital to developing mitigation
strategies. In a broader sense, this study provides a framework for
assessing the risk factors of our modern infrastructure located in
vulnerable coastal areas throughout the world.
A formação e o desenvolvimento da profissionalidade do professor de Geografia - Doi: 10.5212/OlharProfr.v.13i1.0003

Published: February 2021

Este artigo trata do processo de apropriação, produção e desenvolvimento dos conhecimentos/saberes necessários à docência em Geografia. No bojo das pesquisas que têm por escopo a profissionalização dos professores e seu principal corolário, os saberes docentes, pretende-se contribuir, de maneira geral, para o reconhecimento e maior valorização social do trabalho docente e, particularmente, com a melhoria dos processos de formação do professor de Geografia. Para tanto, além de pesquisa bibliográfica que focaliza esse campo de investigação, obtiveram-se dados e informações em observações de aula e entrevistas com cinco professores experientes e especialistas nessa área do currículo escolar que atuam no município de Maringá, PR. Verificou-se que o olhar global dos professores de Geografia sobre seu trabalho e profissão carrega as marcas do campo disciplinar. Os professores percebem que a afirmação do discurso geográfico, seus temas, conceitos e procedimentos no currículo escolar são importantes para o fortalecimento não somente da identidade da disciplina, como da própria profissionalidade. Eles se definem como professores em seu sentido mais genérico, mas buscam-se reconhecer e serem reconhecidos como professores de Geografia. Nesse movimento, apropriam-se de uma determinada tradição geográfica escolar que, alimentada pelo desenvolvimento histórico da ciência de referência e pelo próprio saber produzido e acumulado pela experiência profissional, é avaliada, criticada e recriada continuamente.
Aprendizagem da docência: um estudo com professores do curso pré-vestibular da UFSCAr - Doi: 10.5212/OlharProfr.v.13i1.0008
Authors: Moraes Alessandra Cardoso de
Published: February 2021

Trata-se, este artigo, de uma investigação sobre o processo de aprendizagem da docência de sete professores licenciados e não licenciados do Curso Pré-Vestibular da Universidade Federal de São Carlos (CPV), com o objetivo de analisar as aprendizagens construídas pelos professores no exercício da docência. Apoia-se em estudos sobre a formação de professores, concebendo que a aprendizagem da docência ocorre num continuum por meio da reflexão, na e sobre a ação pedagógica e seu contexto. Foram realizados questionários e entrevistas focalizando como os professores percebem a própria prática. Os resultados mostram que os professores modulam o ensino de acordo com as demandas dos alunos e a análise da experiência vivida ao se envolverem em espaços que, devido à forma de gestão e organização que caracteriza o CPV, extrapolam o âmbito da sala de aula.

Para a escola, um exercício de parceria e leitura de sua função de educar. Durante um ano, dezenove estudantes e um professor universitário, com o apoio da escola, desenvolveram três pesquisas que refletiram sobre dimensões do cotidiano do campo e os desafios para seu desenvolvimento.
Progresso, modernização e sustentabilidade: desafios para as políticas agrícolas. DOI: 10.5212/OlharProfr.v.15i1.0009
Authors: Marcon Telmo
Published: February 2021

O presente texto é resultado de pesquisas bibliográficas já realizadas e discute como o discurso da modernização e do progresso, de modo mais acentuado nas últimas duas décadas, vem conquistando cada vez mais uma posição hegemônica também em relação à agricultura. Nesse movimento, predomina uma perspectiva determinista, segundo a qual não existe qualquer possibilidade alternativa ao modelo dominante que se acha em implantação desde a década de 1950 no contexto da revolução verde, baseado no uso intensivo de produtos químicos. As experiências de produção da subsistência tradicionalmente construídas são desprezadas em nome da modernização e do progresso. Nesse contexto, ganha destaque a exploração intensiva do solo, a destruição de recursos naturais e o uso em larga escala de insumos químicos. Até onde esse modelo sustenta-se? Como ficam as experiências historicamente construídas, desqualificadas como inviáveis? Quais são os riscos desse modelo para as pessoas e para o planeta, ou seja, para o futuro da humanidade? Palavras-chave: Políticas agrícolas. Modernização. Progresso. Sociedade de riscos.

Authors: Ghon Maria da Glória , Zancanella Yolanda
Published: February 2021

O artigo apresenta resultados de pesquisa realizada com egressos e graduandos do Curso de Pedagogia para Educadores do Campo da Universidade Estadual do Oeste do Paraná (Unioeste), campi de Francisco Beltrão e Cascavel, com o objetivo de analisar “O que move o MST na busca do ensino superior para os seus militantes?”. Aborda a relação entre universidade e movimentos sociais, analisando a formação superior universitária dos militantes do Movimento dos Trabalhadores Rurais Sem Terra (MST). Discutem-se o direito da população do campo ao acesso ao ensino superior, a responsabilidade da universidade e seu compromisso com a sociedade civil, e o papel do Estado na garantia dos direitos fundamentais dos indivíduos e grupos. Os resultados evidenciam que as ações dos movimentos sociais refletem-se nas suas conquistas no âmbito social, político e cultural, e que a formação superior universitária é concebida como uma perspectiva fundamental na luta dos militantes do MST, sob o ponto de vista do acesso ao conhecimento prático-teórico aplicável no trabalho, objetivo que inclui a formação política de sua base.
