Published: March 2016

A contact of machinery real engineering surfaces has a complex geometry and is defined by errors at machining, in particular, by macrodeviations, corrugation and roughness. This paper report the consideration carried out on a fluid consumption through an end axisymmetric sealing arrangement formed by a joint of metal surfaces. Sealed environment consumption is defined through a sum of leaks through a slit between surfaces conditioned on corrugation and dripping through a porous layer farmed by surface roughness on contact contour spots. The surface corrugation is modeled by splines according to initial parameters of a corrugation, and as a roughness a surface fractal model is used repeating a real roughness most accurate. On algorithms presented taking into account basic parameters of corrugation and roughness the 3D models of engineering surfaces are created and after their bringing in contact arises a possibility to obtain practically all parameters of contacting defining the impermeability of a sealing arrangement. The application of 3D models allows rendering processes passing in a contact of conjugate surfaces and obtaining some data, for instance, a tortuosity of leaking channels which earlier were chosen according to recommendations which no doubt increases computation accuracy.

Published: March 2016

The flank wear rate of cutting inserts grows in proportion as the force and cutting temperature in-crease which in their turn depend on the value of bevel edge wear. It is possible to reduce the influence of a tool contact area with the work piece upon processes accelerating wear by means of changing the flank form. The paper reports the methods for the estimation of wear resistance of flanks in cutters of different forms. There is offered a new design of replaceable tangential cutting inserts with a combined form of an end flank allowing the considerable increase of a tool life without decrease of work piece quality. The results of new cutting insert manufacturing testing in rail milling operations are presented
HodgeRank Is the Limit of Perron Rank
Authors: Tran Ngoc Mai
Published: March 2016

In the context of pairwise comparison ranking, we show that HodgeRank (row geometric mean), is the limit of Perron Rank (ranking with principal eigenvector) as a certain parameter k goes to 0. This result provides a novel mathematical link between two important pairwise ranking methods. It complements the known result that as k approaches infinity, Perron Rank converges to Tropical Rank. Thus, these three pairwise ranking methods belong to the same parametrized family. Our proof technique is useful for mathematical comparison of these methods. As a sample application, we show that for ranking models with i.i.d noise, HodgeRank is a linear approximation of Perron Rank. In this particular setup, for large numbers of items with sufficiently large score differences, the two methods yield identical ordinal rankings.

Avoiding collapse: Grand challenges for science and society to solve by 2050
Authors: Barnosky Anthony D. , Ehrlich Paul R. , Hadly Elizabeth A.
Published: March 2016

We maintain that humanity’s grand challenge is solving the intertwined problems of human population growth and overconsumption, climate change, pollution, ecosystem destruction, disease spillovers, and extinction, in order to avoid environmental tipping points that would make human life more difficult and would irrevocably damage planetary life support systems. These are not future issues: for example, detrimental impacts of climate change (increased wildfires and extreme weather, sea-level rise, ocean acidification), pollution (contaminated drinking water in many parts of the world), rapid population growth in some areas (contributing to poverty, war, and increasingly frequent migration) and overconsumption in others (a main driver of overexploitation of resources and greenhouse gas emissions), and new disease outbreaks (Ebola, Zika virus) already are apparent today, and if trends of the past half century continue, even more damaging, long-lasting impacts would be locked in within three decades. Solving these problems will require some scientific and technological breakthroughs, but that will not be enough. Even more critical will be effective collaboration of environmental and physical scientists with social scientists and those in the humanities, active exchange of information among practitioners in academics, politics, religion, and business and other stakeholders, and clear communication of relevant issues and solutions to the general public. This special feature offers examples of how researchers are addressing this grand challenge through the process of discovering new knowledge and relevant tools, transferring insights across disciplinary boundaries, and establishing critical dialogues with those outside academia to help effect positive global change.

A microbacia hidrográfica do rio Jundiaí Mirim abastece o município de Jundiaí e está inserida entre as regiões metropolitanas de Campinas e São Paulo, as duas principais do estado de São Paulo. Nessa região, problemas como a escassez dos recursos hídricos, bem como sua qualidade, conflitos entre usuários da água e poluição hídrica são parte da realidade enfrentada pelos órgãos gestores governamentais. O índice de estado trófico (IET) permite a classificação dos corpos d’água conforme aporte de nutrientes no sistema que acabam por estimular artificialmente a proliferação de algas e macrófitas, podendo ocasionar uma série de problemas, dentre os quais, proliferação de algas tóxicas, mortandade de peixes e mau cheiro. Já os macroinvertebrados bentônicos estão entre os organismos mais amplamente utilizados e reconhecidos como indicadores de qualidade do ambiente aquático respondendo a alterações na água, no sedimento e no entorno. O objetivo do presente trabalho foi avaliar a qualidade ambiental da microbacia do rio Jundiaí Mirim com base na avaliação conjunta do índice de estado trófico e na análise rápida da comunidade de macroinvertebrados bentônicos. Foram realizadas amostragens para determinação do IET e análise expedita da comunidade de macroinvertebrados bentônicos em quatro pontos ao longo da microbacia do rio Jundiaí-Mirim. Em conjunto os dados revelam uma situação preocupante da bacia que se encontra em processo de eutrofização, resultando em uma qualidade ruim de suas águas e sedimentos. Além disso, foi registrada a presença do molusco invasor Corbicula fluminea, espécie esta dentre os animais exóticos de maior preocupação no mundo em ambientes de água doce. Recomenda-se o desenvolvimento de um plano de ação com metas de curto, médio e longo prazo para a recuperação do ambiente a fim de se evitarem perdas ambientais e econômicas e desdobramentos sociais adversos. Um índice para análise rápida com macroinvertebrados bentônicos foi proposto.
A ACESSIBILIDADE DE IDOSOS E AS UNIDADES DE CONSERVAÇÃO: REFLEXÕES RUMO À DEMOCRATIZAÇÃO DOS ESPAÇOS PÚBLICOS DE LAZER
Authors: Luiz Fabiane Imenes , Teixeira Juliana Carolina
Published: March 2016

Frente ao processo de urbanização, a busca por atividades de lazer em áreas naturais é cada vez mais crescente. Um dos principais espaços utilizados para a prática desse segmento são os parques, que visam conservar o ambiente e proporcionar a visitação pública. Neles, as trilhas são um dos principais meios de acesso aos atrativos, devendo oferecer segurança e, quando autoguiadas, autonomia aos visitantes. Esse estudo avaliou as condições de acessibilidade para usuários idosos da trilha Peroba do Parque Estadual Lago Azul, em Campo Mourão (PR). Como procedimentos metodológicos, optou-se, em um primeiro momento, por uma pesquisa bibliográfica e documental. Posteriormente, desenvolveu-se um estudo de campo para levantar as competências dos condutores quanto à segurança de visitantes idosos e aos obstáculos enfrentados por esse grupo. Os resultados mostraram que as competências dos condutores atendem parcialmente às necessidades de segurança de visitantes idosos e que a trilha estudada apresenta obstáculos, que limitam a segurança e a autonomia desses indivíduos. As deficiências estruturais observadas resultam das deficiências relacionadas às políticas públicas na área e à responsabilidade do Estado sobre elas. Portanto, a promoção da acessibilidade em trilhas torna-se passo fundamental para que se possa garantir uma maior democratização desses espaços de lazer. Palavras-chave: Idosos. Acessibilidade.

Published: March 2016

Este estudo analisa o construto ‘satisfação dos residentes com o lugar’, com a finalidade específica de propor uma escala para sua mensuração. O pressuposto foi de que a atratividade de um lugar é evidenciada, em grande parte, pela satisfação que seus residentes têm, de modo que se faz necessário monitorar e empreender esforços para elevar o nível de satisfação deste grupo de stakeholders. A partir de uma revisão da literatura da área, definiu-se o construto e avaliaram-se os principais indicadores de satisfação. Em seguida, foi empreendido um esforço de construção de uma métrica, seguindo os passos convencionais de construção de escalas para construtos com mensuração refletiva. Para validação empírica, foram coletados dados das cidades do estado da Paraíba, Brasil: João Pessoa, Campina Grande, Guarabira, e algumas outras pequenas cidades circunvizinhas. Inicialmente foi feita uma primeira atividade de amostragem com a finalidade de limpeza da escala, e a segunda amostragem foi realizada no sentido de validar a escala. A escala final proposta é unidimensional de quatro itens e pode ser utilizada não apenas para cidades, como também para bairros e/ou regiões. A proposição dessa escala tem direta implicação prática na atuação dos gestores de lugares no sentido de oferecer um instrumento de mensuração da satisfação de seus residentes. Academicamente, preenche uma lacuna na literatura da área em termos de métrica na área de satisfação de lugares. Palavras-chave: Residentes. Satisfação. Mensuração.

Published: March 2016

Various environmental conditions (heat waves and drought events) strongly affect leaf and xylem phenology. Disentangling the influence of temperature, precipitation and soil moisture content (AWR) on the forest productivity remains an important research area. We analyzed the impact of climate variability on the leaf phenology (10 sample trees) and radial growth (17 sample trees) of European beech ( L.). The study was conducted on 130-year-old European beech trees growing in a temperate forest stand in the Czech Republic. Detailed 20-year phenological monitoring was performed at the study site (1992â2011). As expected, leaf phenological events were mainly driven by the growing season temperatures. Leaf unfolding was highly affected positively by spring temperatures and the top-layer (to 40 cm) AWR in March. The correlation of tree-ring width with the interpolated climate data was positive significant for the growing season AWR and precipitation signal. Furthermore, the water availability in the top soil layer was found to be an important predictor of tree growth and extremely low growth occurrence. The extended phenological growing season, which was caused by a temperature increase, was not followed by an increased tree-ring width. The examined relationships point out the significance of the water availability in the top soil layer in European beech stands.Fagus sylvatica

Tendo em vista a competição acirrada presente na economia nos dias atuais e a necessidade crescente de conquistar clientes e mantê-los fiéis, o presente trabalho tem como objetivo aplicar a consagrada Teoria das Filas em uma agência bancária com a finalidade de apontar oportunidades de melhorias no tempo de espera dos clientes, a partir do pressuposto de que as filas analisadas seguem a distribuição de Poisson. Tal pressuposto é decorrente da comparação realizada entre a referida distribuição com os dados de chegada dos clientes em todas as filas analisadas. Constatou-se também a existência de filas com sazonalidade na demanda, enquanto outras apresentaram uma demanda regular. A partir do estudo realizado, melhorias no gerenciamento desta agência bancária poderão ser realizadas como, por exemplo, a realocação de funcionários em determinados períodos para funções com maior demanda. Concluiu-se, portanto, que a aplicação da teoria é viável e que pode auxiliar no aumento das vantagens competitivas da agência

O Sistema Penitenciário brasileiro apresenta muitas falhas, que envolvem desde o tratamento dispensado aos presos, como a situação de trabalho dos profissionais atuantes neste cenário. Este fato conduziu à realização desta investigação, a qual teve o propósito de identificar à presença de estresse decorrente das atividades laborais, avaliar o nível de qualidade de vida dos trabalhadores e correlacionar as dimensões de qualidade de vida com o estresse ocupacional entre os dos agentes prisionais. Pesquisa descritiva, transversal e quantitativa, realizada com 35 trabalhadores (70% do universo) atuantes no sistema carcerário de Cajazeiras, Paraíba após parecer 815.685 do Comitê de Ética em Pesquisa da Faculdade Santa Maria. Para a coleta de dados foram utilizados o World Health Organization Quality of Life – Bref (WHOQOL-Bref) e a Job Stress Scale (JSS). A análise foi feita a partir da estatística descritiva e inferencial. Nas comparações entre os domínios de qualidade de vida e os fatores de estresse no trabalho, utilizou-se o teste de Friedman e para controlar o efeito do erro de conjunto realizaram-se testes de bonferroni. Os resultados, quanto ao estresse ocupacional, indicaram que a demanda psicológica foi o que apresentou maior pontuação (3,74) e a falta de controle do trabalho a menor (2,71). O nível de qualidade de vida total dos agentes prisionais apresentou média de 71,07, com maior escore para o domínio social (76,90 pontos) e o menor ao ambiental (62,23 pontos). Ao correlacionar a qualidade de vida com o estresse, houve correlação negativa e significativa da qualidade de vida total com a falta de controle sobre o trabalho (ρ = -0,42; p <0,05) e com o estresse total (ρ = -0,41; p <0,05) mostrando que quanto maiores os níveis de estresse menor a qualidade de vida. Apesar de a qualidade de vida ter sido adequada, o domínio ambiental tem implicado em sua redução, bem como o estresse ocupacional, sendo este mais afetado pela falta de controle do trabalho. Sugerem-se intervenções no campo da promoção da saúde e segurança no ambiente ocupacional, com melhorias gerais nas condições de vida e de trabalho dos agentes prisionais.

ABSTRAK Untuk meingkatkan kepercayaan konsumen luar negeri terhadap produk furnitur kayu Indonesia maka mulai Januari 2015 setiap aktifitas ekspor furnitur harus menyertakan dokumen        V-Legal (Verified Legal). Pada prinsipnya, V-Legal merupakan dokumen yang menyatakan bahwa produk kayu tersebut telah  memenuhi standar verifikasi legalitas kayu sesuai dengan ketentuan Pemerintah RI. Penelitian ini bersifat deskriptif kualitatif dengan melakukan wawancara dan observasi terhadap 11 pelaku usaha furnitur di Jepara. Penelitian ini menggambarkan berbagai manfaat dan kendala yang timbul dari penerapan V-Legal. Banyak faktor yang akan mempengaruhi hasil penelitian tersebut seperti kesiapan para pengusaha untuk menyiapkan dokumen tersebut, serta tanggapan mereka tentang beberapa prosedur yang mereka jalankan dan pemanfaatan fasilitas dari pemerintah ataupun pihak swasta untuk membantu mereka dalam pengurusan V-Legal. Dari hasil dari penelitian ditemukan beberapa kendala seperti masih banyaknya pengusaha furnitur yang belum memahami secara betul mengenai manfaat, tujuan dan alasan dari pemberlakuan V-Legal. Namun, berdasarkan  hasil  wawancara kepada salah satu pengusaha mengatakan ada indikasi kenaikan  permintaan produk furnitur dari Indonesia khususnya untuk pasar Eropa yang mungkin disebabkan oleh naiknya  pamor produk furnitur Indonesia karena mempunyai sumber bahan baku yang jelas dan dapat dibuktikan melalui penerapan V-Legal. Kondisi yang berbalik dengan Negara tetangga; Malaysia dan Singapura yang selama ini juga menjadi pengekspor furnitur namun tidak memiliki cukup hutan sebagai bahan baku sehinggamereka kesulitan untuk membuktikan asal-usul kayu yang mereka gunakan.

One of the environmental problems caused by human beings as a result of their activities is solid waste, the amount will be more and more, which can potentially lead to a variety of complex waste problems. Similarly, one of the central sub districts of the growing fast as urban areas, Desa Kutoharjo. The growing of heterogeneity of the population and land uses, it will emerge as problems of solid waste. Therefore, the village government through Community Self-reliance Agency (BKM) and non-governmental groups trying to implement the stages of sustainable waste management. Various attempts of implementation program has been done by community, such as sorting, ‘takakura’ or composting, but have not been able to run effectively. Along with it, the scavengers have been running their activities, who pick up trash sorting community property. So, the purpose of this article are to examines the activities and presence of scavengers in a state of society that seeks to manage the solid waste by strengthening local institutions in community-based integrated waste management. This article shows that the informal sector has been a well-established network, but it has become a community problem, if the scavengers take the solid waste sorting, especially on trash sorting, which is valuable if recycled. Most of the Scavengers has distinctive characteristics, namely do not care, ignorant with limited capabilities. Thus, their involvement in the management of  community-based sustainable integrated waste is not easy and difficult to implement, especially most people have the same interests as scavengers. However, there are many scavengers-level collectors who can be trusted and people willing to work together with them, especially on trash sorting, such as plastic, metal, glass, paper, paperboard and etc. Therefore, its effectiveness for more sustainable waste management, formal and informal relations sector requires a better cooperation, due the informal sector already has a well established network to manage a solid waste and on the other side the local government officially through BKM that have been formed community groups of waste management.

So these conditions affect the change in the pattern of land use, activity system as well as the pattern of people and goods mobility that are happening in the urban system. The phenomenon of the emergence of new urban areas (cities and towns) in IKK Gemolong causes changes in land use patterns along the road corridor is experiencing rapid development, it is evidenced by the increased activity and physical growth of the city. The conditions were observed with the growth of new activities such as residential, commercial district and other commercial areas. So that it will affect land use patterns, activities systems and people and goods mobility patterns that occur, which in turn will affect the characteristics of the spatial structure of the development of IKK Gemolong formed as a town in Sragen. The focus of discussion such as land use, population activity systems, as well as the people and goods mobility which the influencing factors of the formation of the spatial structure of a city. The study is considered important because as the basis for consideration in the development of towns in the future. This is because the policy of urban development continues in administrative and sectoral nature, so the presence of the regional autonomy policy of development with regional and integrated system and assessed more quickly to implement. This study used quantitative an quantitative study method. The analysis results indicated the characteristics of land use in Gemolong dominated by settlements, while the commercial district developed along the main streets of this town because Gemolong have function as service centers for its surrounding areas. The residents of Gemolong mostly have work in the non-agricultural sectors, such as trade and services, while the population as a farmer is relatively small, so that these conditions indicated that Gemolong says as urban area. The people mobility in Gemolong originated from both internal and external area of the town in destination location of commercial areas to have studying, working, shopping and other purposes. The residents of Gemolong do not have to big cities to access the daily life necessities for since it is already available in Gemolong. Based on the phenomenon of Gemolong have a compact city type of development, while the structure of urban spaces that were formed have view more functioning of each of the regions even though the condition is still occurring mixture of functions. Then, the structure of urban spaces is the type of sector, although not as ideal as yet which happened in developed countries.

Perumahan Bumi Wanamukti merupakan perumahan yang terdapat di Kecamatan Tembalang. Perumahan ini merupakan perumahan yang dibangun oleh Real Estate, mulai huni sekitar tahun 1986 yang terdiri dari empat tipe yaitu tipe 36, 48, 57 dan 70. Perubahan dilakukan tidak hanya pada rumahnya tetapi juga perubahan pada sarana, prasarana dan utilitas umum. Perubahan tersebut menimbulkan dampak ketidaknyamanan terhadap kondisi perumahannya selain itu perubahan tersebut banyak melanggar peraturan yang telah ditetapkan untuk perumahan di Kota Semarang. Berdasarkan pada permasalahan di atas, penelitian ini dilakukan untuk mengidentifikasi perubahan perumahan dari karakteristik penghuni, perubahan rumah, sarana, prasarana dan utilitas umum. Pertanyaan penelitian yang dapat dirumuskan adalah “Bagaimana perubahan perumahan di Perumahan Bumi Wanamukti?”. Penelitian untuk mengetahui perubahan perumahan di Perumahan Bumi Wanamukti ini menggunakan pendekatan kuantitatif. Teknik analisis yang digunakan adalah analisis statistik deskriptif dan analisis faktor. Dilihat dari perubahan rumah yang dilakukan penghuni Perumahan Bumi Wanamukti pada rumah tipe 36, 48, 57 dan 70 sebagian besar adalah perombakan. IMB sebagai salah satu instrumen pengendalian pemanfaatan ruang dirasa kurang berhasil jika dilihat dari hasil analisis, untuk faktor-faktor yang terbentuk pada kempat tipe rumah memiliki kesamaan untuk faktor pertama yang terbentuk adalah dari variabel peningkatan penghasilan. Sedangkan dilihat dari perubahan sarana sebagian besar perubahan lebih kepada kuantitas dimana sarana olahraga yang tersedia menjadi berkurang karena adanya perubahan fungsi, untuk prasarana perubahan terjadi lebih kepada kualitas yang menurun, dan untuk perubahan utilitas umum perubahan terlihat pada kebutuhan penghuni yang meningkat. Sedangkan untuk faktor perubahan sarana, prasarana dan utilitas umum memiliki kesamaan untuk faktor yang terbentuk adalah faktor kondisi pembuangan limbah. Dapat disimpulakan bahwa perubahan rumah memberikan dampak besar terhadap perubahan perumahan, jika dilihat dari bentuk dan faktor perubahan rumah tidak terdapat perbedaan yang signifikan pada setiap tipe rumah.
Jakarta Under Water: The 2007 Flood and The Debate On Jakarta’s Future Water Infrastructure
Authors: Mohsin Anto
Published: March 2016

This paper examines the debate in the wake of the 2007 flood in Jakarta, the biggest one to occur in the city’s history. By analyzing textual sources both online and in the archives as well as interviews with several actors in the debate, I demonstrate that a new sociopolitical condition in Indonesia facilitated a vibrant discourse in the wake of a so-called “natural disaster.” In a democratizing society such as Indonesia, state actors no longer monopolized the social production of a “risk object” or a source of danger or harm. I show that the Indonesian public, who participated in the debate, shaped “networks of risk objects” either by “emplacing” a risk object (i.e. defining an entity as an object and linking it to a potential harm) or by “displacing” it (i.e. challenging the existence of a risky object or delinking it from a putative danger) (Hilgartner 1992). These non-state actors managed to insert themselves into a sphere once dominated by the technocrats, in large part because the press was no longer controlled by the state. In doing so they exposed the messiness and vulnerability of the city’s water management system. The “risk objects” they identified run the whole gamut of entities that make up the entire Jakarta’s water management sociotechnical system, which includes water technologies, laws, practices, institutions, conditions, policies, and the environment.

Udara sangat penting dijaga kelembabannya agar nyaman dalam kehidupan manusia. Udara yang terlalu lembab dapat memicu tumbuhnya bakteri , korosi pada alat-alat logam, dan membahayakan kesehatan manusia. Udara terlalu kering juga menimbulkan ketidaknyamanan bagi kulit manusia.. Dehumidification merupakan proses untuk menurunan kelembaban udara yang terjadi di dehumidifier, dimana uap air diserap saat terjadi kontak dengan udara oleh liquid dessicant sebagai fluida kerja. Penelitian ini menguji pengaruh variasi nosel dan variasi konsentrasi terhadap kelembaban udara dengan menggunakan larutan CaCl2 sebagai liquid dessicant. Di bagian atas dari dehumidifier, liquid dessicant didistribusikan menggunakan spraying nozzle dan pada waktu bersamaan udara bergerak secara counter flow masuk ke dalam dehumidifier dari bagian bawah, dengan menggunakan induced fan yang terletak di atas spraying nozzle pada jarak tertentu. Dimensi nosel bervariasi sebesar 0,2 mm, 0,3 mm, 0,4 mm, dan 0,5 mm, sedangkan variasi konsentari CaCl2 30%, 40%, dan 50%. Debit aliran udara masuk dehumidifier dijaga konstan sebesar 2,35 m3/min, temperatur masuk CaCl2 sebesar 18 OC, serta perubahan kelembaban dan temperatur akan diukur menggunakan sensor suhu dan kelembaban DHT 11. Hasil penelitian menunjukan penurunan kelembaban udara lebih tinggi menggunakan spraying nozzle berdimensi 0,2 mm pada konsentrasi 50% yaitu RH turun 13%.
PEMANFAATAN ABU VULKANIK GUNUNG KELUD SEBAGAI BAHAN ADITIF DALAM PEMBUATAN CETAKAN PENGECORAN LOGAM
Authors: Umardani Yusuf
Published: March 2016

Erupsi gunung berapi selalu mengeluarkan Abu vulkanik yang dikeluarkan dari perut bumi, seperti letusan gunung Kelud pada awal tahun 2014 ini yang mengeluarkan ratusan juta m2 abu Vulkanik. Abu vulkanik salah satu unsur yang terkandung didalamnya adalah lempung/bentonit. Bentonit dalam proses pengecoran logam dimanfaatkan sebagai bahan aditif untuk mengikat antar butiran pasir sehingga pasir bisa dibentuk sebagai bahan cetakan. Kekuatan ikatan antar butiran diuji melalui kuat tekan, mampu bentuk dan kuat geser dari pasir tersebut. Metode penelitian ini dengan cara membuat spesimen dari pasir yang dicampur dengan abu vulkanik 5%, 10 % dan 15%. Kemudian dilihat kekuatan tekan, kekuatan geser dan mampu bentuk serta mampu alir udara atau permeabilitasnya. Pasir cetak dengan tambahan abu vulkanik 15% mempunyai kekuatan tekan sebesar 22,8 kg/mm dan kekuatan geser sebesar 17,7 kg/mm

Penelitian ini bertujuan untuk meneliti pengaruh % berat serbuk SiC terhadap kekerasan dan kekuatan bending material komposit AlSiTiB yang diperkuat dengan serbuk silikon karbida (SiC). Penelitian dilakukan dengan variasi persentase serbuk SiC: 2,5%, 5% dan 7,5 % berat. Pembuatan komposit dilakukan dengan metode semi solid stir casting. Metode ini dipilih agar terjadi pencampuran antara matrik dengan penguat pada suhu semisolid. Pengujian kekerasan dilakukan dengan metode Rockwell sedangkan uji bending dilakukan dengan metode four point bending. Hasil penelitian menunjukkan bahwa, semakin tinggi persentase berat serbuk SiC semakin meningkat kekerasan dan kekuatan bending material komposit
ANALISIS DISTRIBUSI ALIRAN SPRINKLE TEKANAN RENDAH
Authors: Widyanto Susilo Adi
Published: March 2016

Kebutuhan pangan terus meningkat seiring dengan pertumbuhan jumlah penduduk, tetapi pada sisi lainnya daya dukung alam termasuk luas lahan pertanian terus menurun dari tahun ke tahun, sedangkan perubahan iklim menunjukkan pola yang semakin ekstrim. Penerapan teknik irigasi yang mengacu pada analisis kondisi lingkungan perlu dipertimbangkan untuk mengatasi persoalan turunnya produktivitas hasil pertanian. Penggunaan sprinkle sebagai mekanisme pendistribusi aliran air irigasi telah lazim digunakan. Namun permasalahan distribusi aliran merupakan aspek penting yang harus diselesaikan agar dapat mendukung pengotomasian sistem irigasi. Penelitian dilakukan dengan menggunakan empat jenis sprinkle rotari. Setiap sprinkle diuji distribusi alirannya dengan metode mengukuran massa air sebagai fungsi radius posisi sprinkle. Pengujian dilakukan dengan memvariasikan ketinggian air suplai dalam kurun waktu 3 menit. Data karakteristik distribusi aliran sebagai fungsi dari jenis sprinkle dan ketinggian air suplai yang diperoleh digunakan sebagai dasar desain ulang salah satu jenis sprinkle yang akan dikembangkan untuk mendukung sistem irigasi terotomasi. Hasil penelitian menunjukkan bahwa sprinkle yang dijual dipasaran hampir semuanya tidak memenuhi karakteristik distribusi aliran yang baik pada luasan pembasahan. Perbaikan desain secara umum dapat dilakukan dengan mengatur posisi lubang aliran keluaran yang disesuaikan dengan daerah pembasahan yang dituju serta mengubah diamater lubang efektif yang dikaitkan dengan luasan daerah pembasahan dan pertimbangan distribusi tekanan dalam konstruksi sprinkle

The Impact of Education and Occupation on Temporary and Permanent Work Incapacity
Authors: Datta Gupta Nabanita , Lau Daniel , Pozzoli Dario
Published: March 2016

This paper investigates whether education and working in a physically demanding job causally impact temporary work incapacity (TWI), i. e. sickness absence and permanent work incapacity (PWI), i. e. the inflow to disability via sickness absence. Our contribution is to allow for endogeneity of both education and occupation by estimating a quasi-maximum-likelihood discrete factor model. Data on sickness absence and disability spells for the population of older workers come from the Danish administrative registers for 1998–2002. We generally find causal effects of both education and occupation on TWI. Once we condition on temporary incapacity, we find again a causal effect of education on PWI, but no effect of occupation. Our results confirm that workers in physically demanding jobs are broken down by their work over time (women more than men) but only in terms of TWI.
