In recent years, the population and authorities in West Germany have become very concerned with water pollution. In this respect, combined sewage discharges have been pointed out as a major source. Various measures can be considered, which can be ordered into three categories: a redefinition of the objectives of the Urban Drainage System (UDS), the reshaping of the UDS (e.g. extension of the storage capacity) or the modification of its operation. Among the latter measures, Real-Time Control (RTC) constitutes the main option. It aims at a better exploitation of the existing storage potential. As the city of Bremen (Germany) decided, several years ago, to renew the on-line survey and monitoring system of its UDS, the determination of on-line strategies to operate the pumps came to the fore. Methods and tools to investigate the possibility to reduce the pollution loads through improved control strategies have been developed. Some results are presented.

DETERMINATION OF DOLOG’S IDEAL WAREHOUSE BASED ON MINIMUM LOGISTICS COSTERIANA ASTUTYFaculty of Business and Management, Widyatama UniversityJalan Cikutra 204 A, Bandung, Jawa Barat 40125E-mail: [email protected] besar penduduk Indonesia mengkonsumsi beras sebagai makanan utama sehingga memerlukan jumlah beras yang mencukupi kebutuhan dalam waktu yang tak terbatas. Gudang penyimpanan diperlukan untuk mengelola persediaan beras.. Gudang beras harus berada di tempat yang strategis dan mudah dijangkau sehingga memperlancar pendistribusian dan menunjang efisiensi pendistribusian dalam segi ongkos logistik yang minimum. Dolog (Depot Logistik) merupakan agen tunggal Bulog (Badan Urusan Logistik) di Indonesia yang mempunyai tugas utama menjaga stabilitas dan ketersediaan bahan pangan di Indonesia terutama beras. Untuk dapat menjalankan tugasnya, Dolog harus mempunyai gudang beras ideal yang mempunyai kapasitas sesuai kebutuhan permintaan pasar. Penggunaan metode cluster dalam penelitian ini menghasilkan 3 gudang beras ideal dan strategis dalam memenuhi kebutuhan pasar di Bandung yang apabila dibandingkan dengan kondisi gudang sekarang yang sudah ada yaitu di Cimindi, ternyata dapat menghemat sebesar Rp 45.032.203 per tahun atau sekitar Rp125.000 per hari. Sehingga terdapat 2 solusi yang dapat diambil Dolog, yaitu membangun gudang beras baru di lokasi strategis atau tetap menggunakan gudang lama dengan menambah kapasitas gudang sebesar ± 6.000 ton.Kata kunci: dolog, gudang beras, metoda cluster, ongkos logistikABSTRACTMost of indonesian societies consume rice as staple food and therefore need the amount of rice that meet the demand within the infinite time. Food warehouse is needed in order to maintain supplies. Rice warehouse should be located in the strategic location so that it is easy to reach and to avoid the stagnation of supply. In addition, that can also be useful for financing streamline because it can minimize the logistics costs. Dolog as a unit of the agency Bulog is responsible to maintain the stability and availability of basic foodstuffs in the region of Indonesia and to participate in the procurement and supply of basic foodstuffs especially rice. To carry out its duties, Dolog also must have an ideal rice warehouse which its capacity should meet the demand of the rice according to the market supplied. The result of cluster method used in this research suggests that there are three ideal warehouse locations to supply main markets in Bandung. If the three ideal warehouse locations are compared with the existing warehouse, proposed warehouse location donates saving about IDR 45,032,203 per year or approximately IDR 125,000 per day. So there are two solutions can be taken by Dolog that the first is open new warehouses and the second is using the old warehouse and adding the shortage storage capacity by opening additional warehouse at ± 6,000 tons.Key words: dolog, rice warehouse, cluster method, logistics cost

Abstract Benzene is considered a toxic and hazardous pollutant in Tehran metropolis. The storage tanks of petroleum products and refueling in gas stations are among the main sources of benzene emissions. Using the software AERMOD and reviewing the benzene dispersion maps at different distances from 412 storage tanks at 148 gas stations, it was found the permissible distance of the emission source is dependent on various variables such as the number of loading times and the storage capacity. When, storage capacity in the range of 60,000 L to 96,000 L and the number of loading is in the range of 676 to 1,328 times a year, the concentration of benzene at a distance of 30 m of the emission source reaches the annual standard of 5 μg/m3. While, storage capacity in the range of 80,000 L to 128,000 L and the number of loading is in the range of 1,329 to 1,834 times a year, the concentration of benzene at a distance of 40 m of the emission source reaches the annual standard of 5 μg/m3. Also, based on the analysis of data and the linear regression equation, the permissible distance of the emission source can be predicted.

Based on the low cyclic loading test results of vertical stiffener joints between concrete-filled double steel tubular (CFDST) columns and steel beams, the shear transfer mechanism and shear resistance were analyzed in this paper. A conceptual model formulated was presented in terms of equilibrium and stress-strain relationships. The results calculated by the theoretical model and the available experimental data were compared, and then one new concept of shear storage coefficient was proposed for the determination of the shear storage capacity of the joint, which quantitatively explained the ductility failure progression of the joint specimens in the seismic performance test. It was concluded that the vertical stiffener joint had sufficient shear resistance, which met the seismic design principle of strong shear and weak bending. Results show that the ribbed joints have greater shear resistance than unribbed ones; lengthening the overhang of the vertical stiffener can both increase shear resistance and shear storage capacity of the joint; axial compression ratio can reduce the shear storage capacity. The paper also suggests that the joint design should ensure enough safety storage of shear resistance to improve the seismic performance.

1. All determinations of soil moisture should be made to a depth of from four to five feet for wheat and oats, and to a depth of six or seven feet for grasses.2. Unless all the soil under consideration is very uniform, determinations of the hygroscopic coefficient are indispensable. The determination of this value is extremely important even where the soil is uniform.3. The storage capacity for available water of the two soil types studied, may be placed at from five to seven inches of rainfall for wheat and oat crops.4. A better idea of the moisture conditions of the soil at Indian Head may be obtained from a casual examination in the field than from the drying and weighing of the samples, unless the hygroscopic coefficient is considered.5. The moisture stored in the subsoil during the previous summer, and not the frost of the preceding winter, is the cause of the high yields of wheat and oats obtained in southern Saskatchewan.6. The soil of southern Saskatchewan does not remain permanently frozen at any depth.7. Investigations of the moisture conditions to a depth of only 12 to 16 inches are of no value and may often be entirely misleading.
