Abstract

Plastic waste is one of the environmental problems in Indonesia. Plastic waste is a type of waste that is difficult to decompose, so it needs special handling for processing the problem. One alternative offered is by making a plastic chopper machine. One of the manufacturing of a machine is to design and analyze the components used. The blade is one of the important components of a plastic chopper. Model simulation of the blade itself needs to be done to analyze the performance of the blade during the performance of the machine. Simulation modeling is done using CAE software.. The form of meshing in the blade model is using tetrahedral and the meshing ratio is close to 1. The results obtained from the blade modeling process are the maximum Von mises stress on the loading of 300N, 500N, and 700N respectively at 6.752 x 10-3 MPa, 2.845 x 10- 3 MPa and 1,575 x 10-3MPa. While the amount of displacement in the variation of loading 300N, 500N, and 700N respectively has a value of 6.752 x 10-2 mm, 1.125 x 10-1 mm and 1.575 x 10-1 mm. The safety factor in this simulation is produced which has a value of 15, which means it is safe for all loading variations because it has a value of more than 1.

Abstract

Solar panel is popular renewable energy technology because it is environmentally friendly, zero emissions, and environmentally clean.  However, the energy conversion value from solar radiation to electricity is quiet small, more than 70% of solar radiation is discharged into heat energy.  Therefore, a heat collector is needed to take advantage of the heat dissipation from solar panel. In this study, an air heat collector is placed at the bottom of the panel to indicating the potential energy, electrical efficiency and heat efficiency. It was found that solar panels with air heat collectors were able to increase the electrical efficiency of solar panels by 0.70%. The daily primary total energy efficiency value of solar panels with a heat collector is 17.47% higher than a solar panel without a collector. In the future, the results of this research can be a reference for academics and industry to develop their renewable energy potential.

Abstract

The industrial world is currently growing rapidly. The need for JIS S45C as a structural steel is increasing which is used to manufacture machine components. Efforts to improve the mechanical properties of steel can use heat treatment and surface treatment. One of the surface treatments that is often used in the industrial world is shot peening. This study aims to determine the effect of annealing and shot peening treatment on S45C steel. The effect of treatment is indicated by changes in the results of both transverse and surface hardness tests and the microstructure of the treatment results. The result is a change in the value of hardness and microstructure changes in JIS S45C from the effect of annealing and shot peening treatments. The highest hardness in the annealing heat treatment and the 15 minute shot peening treatment was 252.08 kgf/mm2. The shot peening treatment causes the grains to become finer from the surface to the subsurface depending on the distance from the surface to the surface depth. These changes cause the surface and subsurface of JIS S45C carbon steel to increase in mechanical properties.

Abstract

The amount of plastic waste each year will increase by 10% every year which is a problem for a country. Therefore, proper processing of plastic waste needs to be done. Before being processed into plastic waste processing, it is necessary to have a chopping process using a plastic chopping machine. The plastic chopping machine has an important component, namely the chopping knife. Before carrying out the knife manufacturing process, it is necessary to validate the design of the blade that is used with its loading. Model simulation using software is one way to quickly validate the model. This study aims to determine the effect of loading variations on stress, strain, deformation and safety factors of the model. The use of ANSYS R17.2 software is used to analyze the chopping machine knife model with a variation of 5kg / hour, 10kg / hour, 20kg / hour and 50kg / hour capacities. The result is that the stress, strain and deformation parameters have an increase in value with increasing loading variations. The greatest values of stress, strain and deformation are in the variation of 50kg / hour respectively 64.995 Pa; 336.76 and 56,358 x 10-11mm. The value of the safety factor for all variations of loading has a value of 15. The value of the safety factor means that the design of the plastic chopping knife is safe to use up to a loading of 50kg / hour

Abstract

Propeller merupakan salah satu komponen pada kapal penangkap ikan yang memiliki fungsi untuk menggerakan kapal. Efisiensi dari propeller kapal sangat berpengaruh langsung terhadap mesin utama penggerak pada kapal penangkap ikan. Beberapa kondisi, propeller kapal dirancang untuk menyerap daya seminimal mungkin dan memberikan efisiensi gerak kapal semaksimal mungkin. Gaya rotasi propeller kapal akan menciptakan gaya dorong kapal. Gaya yang bekerja pada propeller kapal terjadi karena adanya gaya dari dorongan dan gaya centrifugal serta torsi dari propeller kapal pada setiap blade yang disebabkan revolusi di sekitar sumbu putar propeller kapal. Oleh karena itu, perhitungan tegangan yang dihasilkan dari gaya-gaya pada propeller kapal sangat sulit di perhitungkan secara akurat. Finite Element Analysis (FEA) telah menjadi solusi untuk memprediksi dari suatu kekuatan material yang tidak dapat ditunjukkan dalam teoritis dan memungkinkan desainer untuk melihat semua gaya secara teoritis yang terjadi pada model. Penelitian ini menggunakan material paduan tembaga yang memiliki number of element sebesar 406674 dan jumlah nodes 640321. Hasil yang didapatkan yaitu tegangan maksimu Von Mises yaitu sebesar   . Sedangkan nilai regangan maksimum yaitu sebesar 0,2448 dan nilai displacement maksimum sebesar 133 mm. Nilai safety factor pada penelitian ini sangat rendah yaitu 0. Sehingga geometri desain model propeller sangat rawan terjadi kegagalan atau deformasi saat diaplikasikan.

Abstract

Propeller is part of a key component in fishing boat propulsion. Propeller can provide momentum to the fluid which can be a thrust on the ship. However, The failure of the propeller found prematurely. The failure of the propeller maybe because of overload on the propeller model so the fatigue life of the propeller becomes low. On the other hand, the rapid development of technology can simulate a design model to look for failures that occur. Finite Element Analysis is one of the designer solutions to determine the age of failure of a model and failure-prone areas in a model. This study uses propeller model data from fishing boat with engine 24HP in Dumai City TPI that always fail prematurely. The material used is copper alloy. While the drawing model uses Autodesk Inventor and Finite Element Analysis simulation using ANSYS R17.2 software with the number of model nodes is 51108 and the number of elements of the model is 26268. The results obtained from this study are Von Mises stress on the simulation model that is equal to 613.33 MPa to 0.01164 MPa. While the deformation value due to the effect of loading on the model is 5,3657 mm to 0 mm. These results affect the age of fatigue (fatigue life) on the model with the highest value 109 and the lowest 0. The results of the fatigue life value on the model affect the results of the level of damage and the safety number of the model with successive values of 1032 to 1 and 15 to 0.32446. The conclusion of the result is the propeller will fail prematurely.

Abstract

The propeller was an important component in the fishing vessels marine propulsion system. Brass was widely used as a fishing vessel propeller. Brass was chosen because it has good mechanical properties and good corrosion resistance. The content of seawater in Indonesia has levels of 3% – 3.5% NaCl. In addition to the level of Ion Cl-, environmental factors can affect corrosion rate of material or metal. The environmental factors that affect the corrosion rate are the level of salinity, pH, DO, temperature and TDS. The objective of the present work was to explain the corrosion rate of brass in artificial seawater in Indonesia with exposure time. The material used for research is fishing vessel propeller commercial in Indonesia market. Measurement of the corrosion rate of brass used the principle of weight loss according to ASTM G31-72 (2004). During the corrosion test, the artificial seawater solution was tested for its pH and salinity quality over time of immersion. The result of immersion brass in the artificial seawater shows that the corrosion rate decreases in 1-to-10-days exposure time due to the increase in salinity levels above 30‰. While the results of exposure time immersion above 15 days tends to increase the corrosion rate due to a decrease in pH level. pH level of seawater depends on the environmental conditions and tends not to change significantly.
