Coal dust and cigarette smoke are pollutants found in coal mines that are capable of inducing oxidative stress, the effects of which on blood malondialdehyde (MDA) level and serum superoxide dismutase (SOD) level are still unknown. The purpose of the present study was to evaluate the effect of coal dust and cigarette smoke on levels of MDA and SOD in rats. An experimental study was done on Wistar male rats divided into the following groups: control (C), coal dust exposure (14 days) (CDE), cigarette smoke exposure (14 days) (CSE), coal dust exposure (7 days) followed by cigarette smoke exposure (7 days) (CDE+CSE), cigarette smoke exposure (7 days) followed by coal dust exposure (7 days) (CSE+CDE). All exposures increased MDA levels and decreased SOD activity significantly between groups (p=0.000). All exposure groups had significantly increased blood MDA levels, compared to the control group, although there was no difference between CSE + CDE and CDE + CSE. For SOD levels, all exposure groups had significantly decreased the SOD levels compared to control. But there were no significant differences between CSE vs CDE and CDE + CSE vs CSE + CDE. We conclude that exposure to cigarette smoke significantly increases blood MDA level and decreases serum SOD activity, which was not found in exposure to coal dust. Combined exposures also increase blood MDA level and decrease serum SOD activity significantly.

Cladding merupakan proses pelapisan logam dengan logam lainnya dengan cara pengerolan panas atau pengelasan. Tujuan dilakukan cladding adalah untuk memberikan tambahan lapisan luar pada permukaan material yang mengalami keausan untuk mendapatkan kembali dimensi awal. Pada prakteknya, proses cladding ini akan menyebabkan perubahan struktur pada material akibat proses pemanasan yang diberikan selama proses cladding berlangsung. Berdasarkan data histori perbaikan shaft wringer roll, perbaikan shaft wringer roll telah dilakukan dengan metode cladding menggunakan shielded metal arc welding [SMAW] namun belum diperoleh hasil yang optimal. Tutujuan penelitian ini adalah menentukan kombinasi dan level parameter yang sesuai untuk rekomendasi proses perbaikan selanjutnya. Shaft wringer roll yang digunakan sebagai sampel adalah milik salah satu perusahaan baja terbesar di Kota Cilegon. Material shaft tersebut adalah AFNOR 25CD4 [SAE 4130] dan elektorda Nikko Steel RD-18B yang memiliki karakteristik mirip dengan material shaft wringer roll. Proses cladding dilakukan menggunakan tiga parameter cladding yang dikelompokkan dalam dua level parameter, yaitu arus cladding (110 A dan 170 A), kecepatan cladding (3 mm/s dan 7 mm/s), dan perlakuan panas (tanpa preheating dan preheating pada 200 oC selama 1 jam). Melalui pendekatan full factorial design experiments didapatkan delapan kombinasi parameter proses cladding. Hasil penelitian diperoleh perubahan struktur mikro dan kekerasan material yang paling mendekati raw material adalah sampel dengan parameter cladding menggunakan arus las 110 A, kecepatan pengelasan 3 mm/s, dan diberikan pemanasan awal.

The Company Capital Structure plays an important role in the financing of a company. Planning a good capital structure is an important tool to understand since with the right decision of the appropriate capital structure, the company can reduce the cost of capital (cost of capital), which means to increase the value of the company. The author conducted a research to analyze the influence of several variables, namely liquidity, profitability, size, age and growth on capital structure. The data analyzed are generated from the companies in the list LQ 45 in IDX. The author uses multiple linear regression to analyze the data. The results shows that the variables of liquidity, profitability, size, age and growth of the company negatively affect the capital structure. Of these variables only variable of growth that has a significant at alpha level of 10%.
