The potential use of impregnated coconut wood for power line poles in rural areas of Java
1980 - IRG/WP 3130
Electrification of rural areas in Java needs thousands of power line poles which are relatively cheap in price, but have adequate strength and are fairly durable. A choice of wood species is available in the country. One alternative is coconut wood found in abundance in the villages. This may give a solution to Java's needs since supplies are readily available almost everywhere. Based on ...
