Abstract

This research was aimed to study about the potential of fiber structure teki grass (Fimbristylis sp), linggi grass (Penicum sp) and sianik grass(Carex sp) as natural fibre for fishing gear materials. The parameter of this research are; water content, elongation, breaking strength andhistology of the fiber. This research used the observation and experimental method. The observation method is used to know the fiberstructure and water content of teki grass, linggi grass and sianik grass. The experimental method was used to test the breaking strength andelongation of the objects in wet and dry condition. Based on the histology observation, teki grass has an epidermis layers as fiber structure.It consists of parenchyma tissue and collenchymas tissue.Fiber structure of linggi grass and sianik grass are similar with teki grass. Sianikgrass has the most excessive epidermis layer than others i.e. 5.57 gram. The average water content of teki grass is 1.03 gram, and linggi grassis 0.17 gram. Based on the breaking strength test, sianik grass is stronger than others with average strength 9.05 kgf in wet condition and9.75 kgf in dry condition. Meanwhile, breaking strength of the teki grass and linggi grass is 3.20 kgf and 4.16 kgf in wet condition and 4.30kgf and 5.25 kgf in dry condition. The average of the elongation of sianik grass is longer than others i.e. 24.50 mm in wet condition and18.75 mm in dry condition. The elongation of teki grass is 9.05 mm in wet condition and 11.10 in dry condition. The average of linggi grasselongation is 12.20 mm in wet condition and 12.90 mm in dry condition. Based on the breaking strength and the elongation test, the resultshowed that sianik grass is the most potential natural fiber as fishing gear material.

Abstract

Effort for obtaining effective engine power of fishing vessel and improve thework condition comfortableness on the vessel believed to increase productivity andefficiency of fishing vessel. Assembling of engine accessories effected output ofengine power optimally. Therefore, based on mechanism system analysis of fishingvessel was conducted a study on assembling of engine accessories, such as exhaustpipe, electricity system, rudder and its size calculation method.

Abstract

The integration of engine into the wooden boat needs good knowledge ofeffective engine installation technique. Otherwise, the function of engine will notharmonic with the aims to move the boat properly to be optimum. The effectivenessof engine installation has link to engine foundation, the position of propeller axispoint at the height of keel and the stern. Two systems of engine installation, whichhave experimented and observed its effectiveness; first the lobe point of propelleraxis at the horizontal position just on the middle of the height of the ā€œLā€ pillarbetween the keel and bosom of stern ceiling. Secondly, the propeller horizontal axishole in the point at the mid-height of keel-end and the ceiling of stern as the propellerposition. The result found that the first technique causes the power of engine weakeras compare to the second one; whilst the keel and engine fundation have to bemodified so that the position of engine foundation can be well on horizontal line,which caused change of the keel strength or the boat strength will be lesser. Hence,by mean the propeller axis lobe point at the mid-height between keel-end and thestern bosom found to be effective as the function of engine as power to move the boatworks better with less engine noise and vibration than the other technique.
