This work presents the function of biobased ingredients (palm fiber) as reinforcement in brake pad materials. Reinforcement in brake lining improvise wear stability, wear resistance and friction optimization under a dynamic set of operating variables such as braking force, sliding speed, braking duration and braking temperature. The effect of palm fiber on physical, mechanical and tribological properties of brake pad composite is evaluated. The percentage of palm fiber is gradually increased from 2% to 12% at an interval of 2% as an alternate of rockwool fiber by varying the pressure and speed in a pin on disc tribometer. By increasing the pressure, 8% and 10% shows high friction stability at all speeds. The results show that the raise in the palm fiber quantity increases the hardness, specific gravity and heat swell and the properties, loss on ignition and porosity decreases. The SEM descriptions of the composite indicated that the smaller micro voids occurred in the sample having low palm fiber. Weight gain in the composites were also observed by exposing them in salt water, water and oil.

Purpose of the study: The village people of Pamarican Ciamis West Java Indonesia have great potency to be entrepreneurs. This study aims to implement the strategy to develop rural entrepreneurship potency in Pamarican. Methodology: This is an action research. We are working with several business groups. Triangulation done by conducting sources triangulation, triangulation amongst researchers and theory triangulation. Main Findings: The results shows that a business group can become a forum for the community in developing their business potential, their knowledge and skills increases by the reading material, training and guidance, the increasing knowledge and skills can make them running their business better, the small business activities have been able to increase their income. Applications of this study: This research is expected to contribute to the government in floating the entrepreneurship of rural communities. Novelty/Originality of this study: In this research, we emphasize in improving knowledge and skills to develop the rural communities become entrepreneurs. From 2015-2017, we have provided 300 books of entrepreneurship and other resources to fill their spare time. We hold regular meetings to guide the community to understand the reading material especially in Sukamukti Pamarican. To improve their skills, we also provide entrepreneurship training, mentoring and equipment that necessary to implement reading materials, such as equipment for making salted eggs, cookies and other equipment to several business groups under our guidance.

“…For 6 PF, it was moderate (0.045). It may be due to addition of palm fiber increases the third body abrasion on the surface of the composite, which tends to create friction on the interface [25]. Life of the material is reduced because of high material removal.…”

The effect of palm fiber on properties of automotive brake composite materials is analyzed. The test procedure followed is JASO C 406, which is for passenger car pads. Tribological properties of three brake pads (6 PF, 8 PF and 10 PF) were tested on full-scale inertia dynamometer for various performance parameters such as pressure-speed sensitivity (effectiveness studies) and Temperature sensitivity (fade and recovery behaviour). A pad undergoes all the testing parameters and maintains its low temperature rise in the disc for three pressure sensitivity and two temperature sensitivity tests. By increasing palm fiber content, hardness, heat swell and specific gravity increases, and also porosity and loss on ignition decreases. Test has been conducted using scanning electron microscope to analyse the all three specimens to evaluate the contact plateaus and wear debris during braking. 8% of palm fiber content in brake pad was found to be superior to 6 PF and 10 PF in most of the important tribological properties.
