"Peningkatan sifat mekanis baja perkakas untuk pengerjaan panas telah menjadi perhatian dunia industri sebagai prioritas untuk menghasilkan produk dengan kualitas dan efektifitas produksi terbaik. Penelitian ini dilakukan dengan membandingkan sifat mekanis dari proses High Impact Treatment (HIT) yang mengalami pendinginan dengan media oli pada temperatur 180oC dan pendinginan oleh angin dan sifat mekanis yang diperoleh dengan menggunakan proses High speed quenching. Hasil penelitian ini digambarkan dalam grafik laju pendinginan, harga impak dan nilai kekerasan yang menjadi parameter dalam menentukan hasil yang dianggap lebih baik. Sampel dengan penggunaan metode HIT dengan media quenching oli memiliki nilai harga impak yang paling tinggi yaitu 25 J pada permukaan dan 28 J di bagian tengah sampel. Sementara proses high speed quenching memiliki nilai kekerasan paling tinggi dengan nilai 47 HRC di permukaan dan 45 di bagian tengah. Dengan tujuan meningkatkan ketangguhan baja perkakas, metode HIT dengan media quenching oli pada temperature 180oC dianggap mampu menjadi alternatif pengganti metode High speed quenching.

Improving the mechanical properties of hot work tool steel has become one of industry’s the biggest concern to get a better product by its quality and effectiveness of production. The research was conducted by comparing the mechanical properties of the High Impact Treatment (HIT) which is quenched by oil at temperatures of 180oC and gas quenching, and the mechanical properties which is obtained by using High speed quenching process. The results of this study were illustrated in the cooling rate graph, the impact values and hardness as the parameters that are considered in determining the better process. Samples of HIT process with oil quenching have the best impact value with 25 J on the surface and 28 J on its core. On the other hand, sample of high speed quenching claims the biggest value of 47 HRC for hardness on the surface and 45 HRC in the core. For improving the toughness of tool steel, HIT process with oil quenching medium at temperatures of 180oC is considered to be an alternative High speed quenching process."

"Perusahaan menggunakan pendanaan eksternal melalui utang dan ekuitas pada saat perusahaan tidak dapat membiayai aktivitas operasional dan investasinya dengan hanya menggunakan pendanaan internal. Pecking order theory menyebutkan bahwa pemilihan struktur permodalan perusahaan akan berdasarkan pada rendahnya asymmetric information cost dimana perusahaan menggunakan pendanaan internal sebelum mencari pendanaan eksternal. Namun, dalam trade-off theory, perusahaan akan menggunakan leverage karena adanya tax deductible sehingga perusahaan akan meningkatkan debt ratio untuk meningkatkan corporate value. Semua perusahaan akan menyesuaikan tingkat leverage ke level optimal dimana penyesuaian ini akan memiliki transaction costs. Faulkender, dan Flannery et al., (2012) menginvestigasi faktor yang mempengaruhi speed of adjustment dari leverage. 53% perusahaan di Indonesia termasuk perusahaan Underleveraged dimana memiliki tingkat leverage yang lebih rendah dibandingkan targetnya. perusahaan Underleveraged akan memiliki financial distress risk yang lebih rendah sehingga mereka akan menerbitkan utang baru untuk menyesuaikan tingkat leverage ke level optimal. Penelitian ini menggunakan data panel statis dan panel dinamis untuk menentukan determinan dari leverage yang akan mempengaruhi speed of adjustment untuk perusahaan Overleveraged dan Underleveraged di perusahaan non-finansial di Indonesia. Penelitian ini menemukan bahwa keputusan leverage lebih baik dijelaskan menggunakan pecking order theory dan perusahaan Underleveraged memiliki speed of adjustment lebih cepat dibandingkan perusahaan Overleveraged.

Firms use external funding through debt and equity when firms cannot pay operating activities and investment with just internal funding. Under pecking order theory, firms’ capital structure decisions are based on lower asymmetric information cost that firms would use internal funding before seeking external funding. However, under trade-off theory, firms would use leverage as interest paid by corporate is a tax deductible so increasing debt ratio would raise corporate value. All firms would adjust leverage to its optimal level that leverage adjustment would have transaction costs. Faulkender, Flannery et al. (2012) investigated factors that affect leverage speed of adjustment that transaction cost would impact firms. Firms will adjust their leverage level based on firm characteristics before managers will be sure to raise or lower their leverage level so that they could have an optimal capital structure with lower cost. 53% firms in Indonesia are Underleveraged that they have lower leverage than its target. Underleveraged firms would have lower financial distress risk so they would issue new debt to adjust leverage to its optimal level. This study utilizes panel data techniques and system GMM to find determinant of leverage and interest rate that will impact speed of leverage adjustment of Overleveraged and Underleveraged non-financial firms listed in Indonesian Stock Exchange. Coefficient sign and significance of this study finds that capital structure decisions of Overleveraged and Underleveraged are both better explained by pecking order theory and Underleveraged firms will adjust leverage faster than Overleveraged firms"

"Kecepatan menjadi faktor yang paling besar pengaruhnya terhadap jumlah kecelakaan karena baik kecepatan yang kurang maupun lebih dari batas kecepatan mempunyai resiko terhadap terjadinya kecelakaan di jalan raya. Beberapa kecepatan yang berlaku di jalan yaitu kecepatan rencana (design speed), batas kecepatan (posted speed limit) dan kecepatan yang disarankan (advisory speed). Kecepatan yang konsisten dengan rambu-rambu di alinemen horizontal dapat menyampaikan pesan yang realistis untuk pengemudi dan dapat membuat operasi jalan menjadi lebih efektif. Tujuan dari penelian ini adalah menetapkan rambu kecepatan berkeselamatan yang diambil dari advisory speed dan mengkaji resiko kecelakaan di lokasi penelitian dengan diberlakukannya rambu ini. Hasil penelitian ini menunjukkan bahwa advisory speed diambil berdasarkan Metode GPS. Advisory speed ini berlaku di tikungan, sementara di jalan lurus dilakukan perubahan batas kecepatan menjadi 60 Km/Jam tetapi di lokasi-lokasi khusus ada pengurangan kecepatan untuk mengurangi kecelakaan terhadap pejalan kaki.

Speed becomes the most factors that affect number of accidents because whether the speed is less or more than speed limit have the risk toward accident on the road. Some speed which is applicable on the road are design speed, speed limit, and advisory speed. Speed that is consistent with signs in horizontal alinemen can give realistic message to drivers and can make road operation be more effective. The purpose of this study was to determine safety speed signs which is taken from advisory speed and to review the accident risk in this study location by enforcing this speed signs. The results indicate that advisory speed is taken based on GPS method that is a speed from the measurements of road geometric. This advisory speed is applied at the road bend while in the straight road there is changing of the speed limit become 60 Km/Jam but at special locations such as school there is a reduction due to reduce the accident risk toward pedestrians."

Objective : To know the effect of treadmill exercise and overground walking program on velocity and capacity of walking in stroke patients in dr. Hasan Sadikin hospital, Bandung

Design : Pre- and post treatment with a control group.

Subject : A sample of 23 ambulatory individuals after a stroke more than 3 months previously.

Setting : Physical Medicine and Rehabilitation Department, dr. Hasan Sadikin Bandung.

Intervention : The experimental group participated in a 30-minute treadmill and overground walking program, 3 times a week for 4 weeks. The control group was asked to walk at home for at least 30 minutes as fast as they can, 3 times a week for 4 weeks.
