    Sumur gali merupakan salah satu sumber penyediaan air bersih bagi masyarakat di pedesaan dan perkotaa. Sumur gali harus ditunjang dengan konstruksi sumur yang baik dan jarak lokasi sumur dengan sumber pencemar yang sesuai dengan yang dipersyaratkan, serta tindakan masyarakat dalam menggunakan sumur gali yang tepat, agar air sumur gali terbebas dari pencemaran, dan dapat dikonsumsi oleh masyarakat secara aman. Penelitian ini bertujuan untuk mengetahui hubungan kualitas bakteriologis air sumur gali pada kawasan permukiman dengan tingkat kepadatan tinggi, yaitu Dusun Blimbingsari; dan kawasan permukiman dengan tingkat kepadatan rendah, yaitu Desa Hargobinangun; serta mengetahui gambaran kondisi fisik sumur gali dan pengguna sumur gali terhadap kandungan Escherichia coli.Pengambilan sampel dilakukan secara purposive sampling, yaitu pada 8 (titik) sumur gali. Pengamatan kondisi fisik sumur gali menggunakan checklist sebagai instrumen penelitian, sedangkan perilaku pengguna sumur gali menggunakan kuesioner. Pengujian kualitas bakteriologis air sumur gali dilakukan dengan menggunakan Biosensor TECTA TM B16. Biosensor TECTA TM B16 merupakan alat pengukuran kualitas air untuk mendeteksi dan mengetahui konsentrasi Escherichia coli dengan metode Colony Forming Units (CFU). Hasil penelitian menunjukkan bahwa jumlah Escherichia coli bervariasi antara 0 CFU/100 ml sampai 1.049 CFU/100 ml. Berdasarkan hasil analisa, pada Dusun Blimbingsari terdapat hubungan yang positif antara konstruksi sumur gali dan tindakan penggunanya terhadap kualitas bakteriologis air sumur gali. Sementara itu pada Dusun Wonorejo terjadi hal yang sebaliknya. Hal ini disebabkan oleh beberapa faktor, anatara lain tingkat kepadatan penduduk yang berbeda. Untuk itu perlu adanya perhatian dari masyarakat dalam membuat sumur gali yang aman dan baik, serta memerhatikan tindakannya dalam menggunakan sumur gali agar diperoleh kualitas air yang memenuhi syarat kesehatan

    Tourism is one of the most significant contributors to the construction sector in Indonesia, with the contribution around 13.9 percent of the total GDP in 2012. In connection with the government\u27s efforts in improving the contribution of tourism in an effort to boost economic growth while improving the welfare of society, then the increase in tourism investment as focus in the development program, the goal for the activities can provide added value as well as lead to increased production that will be produced. If it is known that the average investment for the tourism sector is Rp. 2.73 billion during the period 2006-2012. This figure also shows that the contribution of tourism investment to total investment amounted to only 6 percent (Kemenpraf, 2012), in other words, an investment in the tourism sector has not been able to provide optimal contribution to the national economy development. Based on the fact that some of the problems arising from the government\u27s efforts to boost trade and investment in the tourism sector continues to be done. The determinant factors of the amount of investment and trade from the Indonesian tourism and other countries to be considered and used as the basis of decision-making reference. Similarly, the amount of trade and investment flows to and from outside the State, are also worthy of consideration. To answer the problems, we use the gravity model as methodology and construvt the model of investment and trade of flows which consists of 5 models: the model of the flow of Indonesian tourism investment, exports of goods and services models Indonesian tourism, imports of goods and services model of tourism in Indonesia, Indonesian tourism demand flow model, and the model Indonesian tourism supply. Based on the results of the analysis using the five models were obtained magnitude of investment inflows to Indonesia influenced by the population of the country of origin of tourists and mileage of the country of origin of foreign tourists to Indonesia, where the influence of explanatory variables endogenous variables as a whole is at 0:42 at a significance level of 95 percent. The magnitude of the flow of goods and services exports of Indonesian tourism is affected by the distance variable, price of Indonesian tourism in the country of origin of tourists, exchange rate against foreign currencies origin of tourists, population, tourism and exports of the previous year are variables that significantly affect the confidence level of 95 percent, the magnitude of the effect was 92.7 percent and this shows considerable influence.In the model the flow of goods and services for Indonesian tourism, we use a variable distance, Indonesian GDP, the exchange rate, the price of Indonesian tourism in the countries of origin of tourists and imports of goods and services in the Indonesian tourism previously an influential variable significantly (at 90 percent confidence level), and in general of the statistical results obtained by the relationship between the value of imports of goods and services to the Indonesian tourism is the independent variable by 96 percent. In the model flow of Indonesian tourism demand, the estimation results indicate that the tourism demand variable by independent variables Indonesian GDP, GDP of the country of origin of tourists, tourism for Indonesia, Tourism for the competing countries of ASEAN countries, and tourism consumption by foreign tourists in Indonesia as significant variables in the real level of 0:05 with the magnitude of the effect is at 93.2 percent. Statistically, the result also define there is relationship between magnitude supply of Indonesian tourism deals with variable-GDP Indonesia, Indonesian tourism price, exchange rate, domestic consumption, and consumption in other countries as variables significant (at significance level 0.05) effect on variable deals with the influence of Indonesian tourism amounted to 95.6 percent and the remaining 4.4 percent are influenced by other factors outside of the study such as inflation, interest rates, and investment tourism

    Stochastic Models on a Ring and Quadratic Algebras. The Three Species Diffusion Problem

    Full text link
    The stationary state of a stochastic process on a ring can be expressed using traces of monomials of an associative algebra defined by quadratic relations. If one considers only exclusion processes one can restrict the type of algebras and obtain recurrence relations for the traces. This is possible only if the rates satisfy certain compatibility conditions. These conditions are derived and the recurrence relations solved giving representations of the algebras.Comment: 12 pages, LaTeX, Sec. 3 extended, submitted to J.Phys.

    Nuclear Isospin Diffusivity

    Full text link
    The isospin diffusion and other irreversible phenomena are discussed for a two-component nuclear Fermi system. The set of Boltzmann transport equations, such as employed for reactions, are linearized, for weak deviations of a system from uniformity, in order to arrive at nonreversible fluxes linear in the nonuniformities. Besides the diffusion driven by a concentration gradient, also the diffusion driven by temperature and pressure gradients is considered. Diffusivity, conductivity, heat conduction and shear viscosity coefficients are formally expressed in terms of the responses of distribution functions to the nonuniformities. The linearized Boltzmann-equation set is solved, under the approximation of constant form-factors in the distribution-function responses, to find concrete expressions for the transport coefficients in terms of weighted collision integrals. The coefficients are calculated numerically for nuclear matter, using experimental nucleon-nucleon cross sections. The isospin diffusivity is inversely proportional to the neutron-proton cross section and is also sensitive to the symmetry energy. At low temperatures in symmetric matter, the diffusivity is directly proportional to the symmetry energy.Comment: 35 pages, 1 table, 5 figures, accepted by PRC, (v3) changes in response to the referee's comments, discussion for isospin diffusion process in heavy-ion reactions, fig. 5 shows results from a two different isospin depndent uclear equation of state, and a new reference adde

    Scroll waves in isotropic excitable media : linear instabilities, bifurcations and restabilized states

    Full text link
    Scroll waves are three-dimensional analogs of spiral waves. The linear stability spectrum of untwisted and twisted scroll waves is computed for a two-variable reaction-diffusion model of an excitable medium. Different bands of modes are seen to be unstable in different regions of parameter space. The corresponding bifurcations and bifurcated states are characterized by performing direct numerical simulations. In addition, computations of the adjoint linear stability operator eigenmodes are also performed and serve to obtain a number of matrix elements characterizing the long-wavelength deformations of scroll waves.Comment: 30 pages 16 figures, submitted to Phys. Rev.
