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

The performance of the main engine of a fishing vessel becomes less than optimal when its cooling system does not function properly. Centrifugal pumps, as an important component of the cooling system, require special attention in selecting maintenance methods to maintain stable performance. This study aims to investigate the maintenance strategy of centrifugal pumps in the cooling system of the main engine of a fishing vessel. The Failure Mode and Effects Analysis (FMEA) method is used to analyze maintenance strategies based on RPN values. The resulting RPN value can indicate the maintenance strategy that needs to be carried out. The highest RPN value and the failure mode category that requires special attention are analyzed using a histogram diagram. While the root cause of failure is clarified with a fishbone diagram. The results show that the highest failure mode is damage to the pump impeller due to corrosion. The main cause of this failure is found in the selection of impeller materials that are less suitable for working conditions and the environment. Predictive maintenance strategies are considered as a solution to overcome pump impeller problems. This study provides insight into choosing the right maintenance strategy, especially for fishing vessel engines.

Abstract

Steel is one of the metals that is widely used in today's rapidly growing industrial world. The need for manufacturing machine components is increasing. 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 normalising and shot peening treatments on S45C medium carbon steel. The effect of the treatment is indicated by changes in microstructure results and surface and transverse hardness testing of the treatment results. The result is a change in the microstructure and hardness value of S45C carbon steel from the effect of normalising and shot peening treatment. 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 sub surface of S45C carbon steel to experience an increase in mechanical properties. The highest hardness in normalising heat treatment and shot peening treatment at 20 minutes was 316.4 HV.

Abstract

Al-Zn alloys are widely utilized in industries such as automotive, aircraft manufacturing, and advanced military equipment due to their exceptional strength-to-weight ratio. Among various fabrication methods, metal casting is a commonly used technique for producing structural components from these alloys. However, a significant challenge with metal casting is the reduction in mechanical properties compared to the base material before melting. This reduction highlights the need for research to identify the optimal casting conditions, particularly the casting temperature, which plays a crucial role in maintaining and potentially enhancing the material's mechanical properties. Aluminum alloy 7075, known for its high strength, was selected for investigation. According to the Al-Zn phase diagram, the melting point of aluminum alloy 7075, based on the weight percentage specified by the Standard Aluminum Association, is approximately 660°C. Experiments were conducted by varying the pouring temperature during casting in 30°C increments above this melting point. Specifically, the alloy was melted and cast at three different temperatures: 690°C, 720°C, and 750°C. The mold temperature was consistently maintained at 220°C to isolate the effects of the pouring temperature. Results indicate that increasing the casting temperature significantly affects the alloy's microstructure and mechanical properties. As the casting temperature increases, the cooling rate decreases, leading to a finer grain structure. This finer grain size directly contributes to an increase in hardness, suggesting that higher casting temperatures can enhance the mechanical properties of Al-Zn alloys. These findings emphasize the importance of precise control over casting temperatures to optimize the performance characteristics of aluminum alloy 7075 in high-strength applications.
