Two kinds of stresses in the gear teeth are root bending stress and tooth contact stress. These two stresses results in the failure of gear teeth. The root bending stress results in fatigue failure and contact stress results in pitting failure at the contact surface. The stress analysis used to minimize gear failure in the design of helical gear. It is also optimize the design of helical gear ...

ABSTRACT
High carbon steel generally has a high hardness but lower ductility. To obtain a hard and ductile material, surface hardening can be done on a low carbon steel. Surface hardening can be achieved by hard chrome plating. The objectives of this research were: (1) Conducting the process of hard chrome plating on low carbon steel, (2) Knowing the increasing of surface hardness of low-carbon steel after the plating process in time variations, (3) Knowing the ...

ABSTRACT
This study aims to investigate the characteristics of stationary diesel engines which use a mixture of diesel fuel - biodiesel from sunan candlenut seed. Experiments were done with diesel fuel, B5, B10, B15, and B20 with a variety of engine rotation and load variations. The results showed that the values of torque, power and thermal efficiency when the engine uses B5, B10, B15, and B20 tends to decrease if compared when engine use diesel fuel. ...

ABSTRACT
Indonesia is endowed with abundant natural wealth capable of being transformed into an energy source. However, until now the utilization of natural resources can not be optimally processed.
One alternative solution to make the fuel as a substitute for LPG is to fuel the briquettes. The general purpose of this research is the manufacture of briquettes from waste materials such as rice husk and
garlic skin. While the specific purpose of this research ...

ABSTRACT
The position of the sun in the sky always changes periodically. A lot of research has been done
to follow the sun's motion using a solar tracking system to increase the amount of solar energy that can
be absorbed. The solar tracking system can be grouped into passive and active system. Active sun tracker
system uses motor drive in following the motion of the sun. The current active tracking system is ...
