Purpose. Estimation of the influence of non-stationary blast-furnace smelting on the thermal state of the cooling system. Methodology. Analysis of changes in the meanings of thermocouples installed in the body of the cooling system plates, under different operating conditions of the blast furnace. Results. The study of the influence of transitional modes of blast-furnace smelting on the temperature change of the cooling-system plates at the joint use of natural gas and coal-pulverized fuel, under conditions of a low-intensity blast furnace operation and using pulverized coal with a consumption of more than 110 kg/ton of pig iron. Findings. The peculiarities of the influence of transitional modes of blast-furnace smelting on the thermal state of the cooling system are established: incl. with various fuel additives for blasting and with the operation of the furnace with reduced intensity. Practical value. The results presented in the article can be used in the design of the cooling system, as well as in the selection of rational operating modes of the blast furnace. Keywords. blast furnace, PCI technology, natural gas, cooling-system plates, thermocouple.

Hierarchy Process

Usaha Kecil Menengah (UKM) adalah salah satu penggerak perekonomian suatu daerah, termasuk Kota Sorong. UKM di Kota Sorong belum berkembang secara optimal. Ada beberapa penyebab diantaranya adalah mengenai finansial, lokasi, bahan baku dan lain-lain. Untuk menyelesaikan permasalah tersebut peneliti terdorong untuk melakukan pengembangan Aplikasi yang dapat membantu menentukan prioritas UKM yang sesuai dengan kondisi pelaku usaha. Pada penelitian ini akan digunakan metode Analitycal Hierarchy Process (AHP), untuk pengambilan keputusannya. Metode AHP dipilih karena mampu menyeleksi dan menentukan alternatif terbaik dari sejumlah alternatif yang tersedia. Dalam hal ini alternatif yang dimaksudkan yaitu UKM terbaik yang dapat dipilih oleh pelaku usaha sesuai dengan kriteria yang telah ditentukan. Penelitian dilakukan dengan mencari nilai bobot untuk setiap atribut, kemudian dilakukan proses perankingan yang akan menentukan alternatif yang optimal, yaitu UKM. Aplikasi Sistem Pendukung Keputusan yang dikembangkan berbasis Android, dimana pengguna akan mudah menggunakannya sewaktu-waktu jika terjadi perubahan bobot pada kriteria atau intensitas.  Hasil akhir menunjukkan bahwa metode AHP berhasil diterapkan pada Aplikasi Penentuan Prioritas Pengembangan UKM.
