Abstract

Seaweed is an abundant aquatic product in Indonesia, where around 80% of its production is sold dry. The drying process of seaweed is done in 2 ways, namely direct sunlight or a drying machine method. Seaweed drying machines require a power transmission system to optimize the drying process. The aim of this study is to design a transmission system for a ratary dryer drying machine. The method used in this study is the design and selection of a sprocket and chain transmission system. The research result showed that the chain used was number 25, a single chain with 59 links and a ratio of 15 sprocket pins to 38. The axle distance is 100.4 mm using steel shaft material bearing with the symbol S30C with the drip lubrication method. The sprocket and chain that have been designed were capable of transmitting 14 watts of electric dynamo energy with a torque of around 4.75 Nm at 19.56 revolutions for a load of 1 kg of seaweed.

Abstract

In this modern era, noise has become an increasingly common and significant problem in everyday life, thus requiring the use of sound absorbers to address this noise issue. This research created a sound absorber using coconut husk waste through the impedance tube method. Sound absorbers can be made by utilizing readily available waste materials, such as coconut husk waste. The effectiveness value of the coconut fiber absorption coefficient was tested using the impedance tube. The research method employed was the impedance tube method, with variations ranging from level 1 to level 5 and frequencies of 200 Hz, 400 Hz, 600 Hz, and 800 Hz. The impedance tube lengths used in this study were 50 cm and 100 cm. The highest absorption result at a tube length of 50 cm was found at level 1 with a frequency of 200 Hz. At a tube length of 100 cm, the highest absorption value was observed at level 2 with a frequency of 600 Hz. Based on this research, it was concluded that coconut husk can minimize noise and serve as an effective sound absorber.

Abstract

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.

Abstract

Indonesia is a country that has a region rich in natural resources, including water. With the existence of this natural wealth, until now many have utilized water as a Hydroelectric Power Plant (PLTA). PLTA is a generator that utilizes potential and kinetic energy through water to produce electrical energy. This study aims to determine the Archimedes screw turbine, to obtain the results of laboratory-scale Archimedes screw turbine efficiency tests. This study uses an experimental method carried out at the Conversion Laboratory of the Mechanical Engineering Department, Borneo Tarakan University. Archimedes screw turbine with a frame length of 120 cm, width 110 cm, height 140 cm, uses a suction pump engine to suck water with a power of 5.5 HP and uses a screw with 8 threads, the turbine shaft has a shaft diameter of 10 mm with a length of 1 m, the distance between the threads is 12 cm and the inner diameter of the thread is 2.54 cm, the outer diameter is 20 cm. The highest turbine efficiency value or turbine performance is at an angle of 35o, namely 0.051% because the 35 o slope of the water pushes the screw very well so that the rotation obtained is more maximum than the 15 o and 25 o slopes.

Abstract

In this study, the composite was reinforced with waste from instant noodle packaging consisting of polypropylene (PP) plastic. The creation of composites using PP as a filler was the purpose of this study. Impact and hardness testing were the composite variant without filler (100%/0%) and variation B (15%/10), with value of 80,5 Shore D and 67 shore D, accrding to analysis of research data. Particle addition composite materials’ impact strength could be increased by adding chopped plastic trash. With a composition of 15%/85% and an impact strength of 0.099 J/mm², composite variantion B had the maximum impact strength. When instant noodle wrapper plastic waste was combined with epoxy resin, a composite material was created. This matrials’ mechanical strength could be increased by increasing the instant noodle wrapeper fiber content and decreasing  the epoxy resin composition this demonstrated that the primary filler for boosting mechanical strength was instant noodle wrapper fiber. The fibers in the instant noodle wrapper were what gave it iss increased mechanical strength, but because so much filler was employed, the interface between in and the  matrix did not bind. The fiber would lift in a mechanical test.
