Abstract

Alabio ducks (Anas Plathycus Borneo) developed in the Alabio area of Hulu Sungai Utara Regency, South Kalimantan with a duck population in 2006 recorded at 3,487,002 heads. So far, alabio ducks have only been used for meat and eggs, even though the feather part of this one poultry can also be used as a composite raw material because of its relatively strong and elastic nature. To improve the quality of the composite, duck feathers are combined with rat purun fibers (eleocharis dulcis) so that they become Hybrid composites. Fraksi volume Hybrid composite Duck Feathers and Rat Purun Fiber are as follows 10% : 90 %, 20% : 80%, 30% : 70%, 40% : 60%, 50% : 50%, 60% : 40%, 70% : 30%, 80% : 20%, 90% : 10%. This study used experimental methods. From the results of the study, it is known that the value of tensile and tensile strength stress and bending strength decreased as the percentage of rat purun fibers decreased compared to the percentage of duck feathers.

Abstract

ST 41 steel is a low carbon steel, has a relatively low surface hardness, so it requires additional heat treatment to improve resistance to wear and cyclic loads. This study aims to examine the effect of variations in cooling media on the mechanical properties of ST 41 steel, especially hardness and fatigue resistance. The variations in cooling media used were water, SAE 20W-50 oil, and air at a temperature of 950°C with a holding time of 15 minutes. The heat treatment process includes preheating and hardening, followed by quenching using the three media. The results showed that the hardness of the steel increased significantly after heat treatment, with the highest value in water cooling (171 HV). In fatigue testing, untreated ST 41 steel showed 71,651 cycles, while heat treatment with oil, air, and water reduced the number of fatigue cycles to 30,571.67, 19,461, and 43,402.33 cycles
