Abstract

Buluhcina is one of the villages in Siak Hulu, Kampar District, Riau Province. The natural wealth potential in Buluhcina includes: (1) several villagers develop cage fish cultivation; (2) the river along the village as a natural potential has lots of fish needed by the community; and (3) lakes and swamps that have the potential to be developed for new jobs. From the community service activities in Buluhcina, it was concluded that: (1) this fish feed molding machine is capable of producing fish feed, the feeds is produced from the machine must be dried by conventional drying (the heat from the sun). (2) Running test for the production of fish feeds that have been made are used as samples of fish feed developed in Buluhcina. Operational training activities for produce the alternative fish feed have been successfully carried out in Buluhcina.

Abstract

The tensile strength and tear resistance properties of pineapple leaf fiber can be improved as a new woven fabric product. This paper aims to experimentally investigate the effect of variations in alkali treatment using sodium hydroxide on the tensile strength of single fibers and tear strength of pineapple leaf fiber woven fabrics.  Alkaline treatment was carried out with variations in sodium hydroxide concentration of 2%, 4%, 8%, 10% and non-alkaline. Alkali treatment on single pineapple leaf fibers affected the tensile strength. The results showed that single pineapple leaf fibers non-alkali treatment had a tensile strength value of 80 N/mm2 and the alkali treatment with a percentage of 8% had the highest tensile strength of 108.57 N/mm2. Alkali treatment on pineapple leaf fibers affects the tear force of woven fabrics made from pineapple leaf fibers. The results showed that non-alkali-treated woven fabrics had a tear force of 47.40 N and the alkali treatment with a percentage of 8% experienced the highest force of 53.98 N. Single pineapple leaf fibers with 8% alkali treatment contained 87.78% cellulose. This shows that the effect of alkali on pineapple leaf fibers can increase the percentage of cellulose, resulting in higher mechanical properties of the fiber. At an alkali percentage of 10%, mechanical properties decreased.
