<![CDATA[One of the first steps in order to utilize ocean waves as electrical energy is to create a medium that can be a means of observing wave characteristics. In this research, a laboratory-scale flap model wave tank was designed. Wave tanks can minimize the use of time and cost in the development of technology that uses ocean waves as a source of energy. The purpose of this research is to design a wave tank with a flap model wave maker, and determine the length and height of the waves produced. This laboratory scale flap model wave tank has a size of 150 cm x 35 cm x 35 cm and uses an electric motor with a power of 200 Watts. The wave tank can work with 22 Watts of electric power and an electric motor rotation of 120 rpm.

<![CDATA[Public consumption of bottled drinking water continues to increase. Single use plastic bottled water is still an option, this increases plastic waste. The main cause is that plastic cannot be decomposed so it has a bad impact on the environment. Plastic waste recycling has been done to reduce plastic waste but is still in low quantities. One of the recycling processes of plastic waste bottles can be utilized as composite materials. Composite consists of elements namely matrix and filler. In this study, the composite is composed of epoxy as a matrix and plastic bottle waste as a filler. The composition of the filler used ranges from 12.5%, 15%, 17.5%, 20%. The composite was made using the hand lay-up method. The composite that had been made was tested for hardness and impact to observe its mechanical properties. From the results of the research test, it was obtained that the greater the variation of the filler used, the lower the impact strength and hardness values. The highest impact strength was 1.02 J/mm2 Joule at a variation of 12.5%. The highest data results from the hardness test in this study were at a variation of 20% of 75.33 shore D.]]>

<![CDATA[Coconut fiber is one of the versatile natural materials with various applications in various industries. Coconut fiber is used in the manufacture of ropes, fabrics, and other textile products. This fiber is often used in the production of sacks, mats, and wickerwork. Coconut fiber can be used as a mixture in the manufacture of concrete and other building materials. Coconut fiber can also be used as a composite material. Composites consist of two elements, namely matrix and filler. This study aims to determine the effect of coconut fiber variations on impact strength and hardness. The composition of the filler is around 10, 15, 20 (%) of coconut fiber with matrix resin. The addition of filler is accompanied by a reduction in the matrix used from 100% epoxy. Specimens with NaOH treatment were made with 9 specimens and without treatment were made as many as 3 specimens. Composites were made by hand lay-up process. The composites that have been made were then subjected to mechanical tests, namely hardness and impact. The highest hardness test data results with NaOH treatment at variation (15%/85%) were 75 shore D. The lowest hardness at variation (10%/90%) was 63 Shore D. While without treatment the research results showed the highest at variation (10%/90%) was 74 Shore D. And the lowest hardness at variation (20%/80%) was 63 Shore D. The highest impact strength of NaOH treatment was at variation 20% absorbed energy of 3.28 Joules and impact toughness of 0.020 J/mm2. The highest untreated composite was at variation 20% absorbed energy 0f 3.39 Joules and impact toughness of 0.021 J/mm2.]]>
