Abstract

Pembelajaran di era 4.0 membutuhkan literasi yang sangat penting agar kompetensi siswa dapat ditingkatkan sesuai dengan perkembangan global. Namun, masih ada beberapa siswa SMK yang kurang dalam literasi, terutama dalam jurusan permesinan kapal bidang gambar teknik karena minimnya judul buku yang tersedia. Oleh karena itu, pengabdian kepada masyarakat bertujuan untuk meningkatkan literasi dalam bidang gambar teknik mesin, guna meningkatkan pengetahuan dan keterampilan siswa SMK jurusan permesinan. Metode yang digunakan dalam kegiatan ini adalah ceramah dan bedah buku untuk menyampaikan materi tentang buku gambar teknik. Pengumpulan data untuk mengevaluasi keberhasilan kegiatan menggunakan skala likert. Kegiatan ini dilakukan dalam satu hari dengan melibatkan 15 peserta dari siswa jurusan permesinan SMK N 2 Dumai sebagai peserta pengabdian kepada masyarakat. Sebelum materi disampaikan, peserta mengikuti pre-test, dan setelah kegiatan, mereka diberikan post-test dan kuesioner kepuasan. Hasil analisis menunjukkan bahwa terjadi peningkatan dari pre-test ke post-test sebesar 82,86%, dan tingkat kepuasan peserta mencapai 67%, menandakan bahwa kegiatan ini sangat memuaskan. Dalam analisis ketercapaian kegiatan ini, dari kategori penyajian, dampak kegiatan, dan kebermanfaatan kegiatan, nilai yang dicapai secara berturut-turut adalah 90,6%; 91,1% dan 94,4%. Dengan rata-rata nilai ketercapaian sebesar 92,03%, dapat disimpulkan bahwa sebagian besar kegiatan ini berhasil.

Abstract

Diamond-Like Carbon (DLC) coatings are well-regarded for their high hardness, low friction coefficient, and excellent wear resistance, making them suitable for enhancing surface properties in demanding industrial applications. This study aims to analyze the effect of DLC coating on HQ 805 steel, focusing on improvements in surface hardness and surface roughness. HQ 805 steel, which is known for its mechanical durability, was coated using the Physical Vapor Deposition (PVD) method to achieve a uniform and adherent thin film. Hardness was evaluated using the Vickers microhardness test, while surface roughness was measured with a profilometer. Results showed a significant increase in surface hardness, with the coated samples achieving up to 798 VHN. It represented a 25–30% increase compared to the uncoated steel at 355 VHN. Surface roughness exhibited only a slight increase (5–7% Ra), indicating the thin layer and uniform deposition achieved with DLC without adversely affecting the surface finish. These results confirm that PVD-applied DLC coatings can effectively enhance the mechanical surface performance of HQ 805 steel without compromising surface quality. The optimal coating condition was found at 400°C for 4 hours. This research shows the potential application of DLC-coated HQ 805 steel in high-wear industrial environments extending component service life and improving operational efficiency.

Abstract

The refrigeration system in the fishing process is important for maintaining the quality of the catch. However, the design of small-scale refrigeration machines is still not common, so it is an interesting study. Therefore, this study aimed to evaluate the design of small-scale fishing vessel refrigeration machines. Field studies are needed in machine manufacturing to observe the components required to match the refrigeration machine components onboard fishing vessels. This uses a direct observation method to determine the components of the refrigeration machine on the ship. Furthermore, the performance of the machines produced will be tested through the load cooling process. Parameters determined in the performance test include monitoring temperature (suction and discharge), pressure (suction and discharge), evaporator temperature, load temperature, COP (Coefficient of Performance), and compressor power. Refrigerant temperature measurement uses an insulative principle so that ambient temperature does not affect it. The result is that the machine produced has a capacity of 35 l or 15 kg of load. Meanwhile, in the performance test, the COP and electrical power generated while cooling the load for approximately 4 hours were 2,42 and 507 W, respectively. The results of this design were successful and did not experience failure. The significanceof this study can be used as a reference source for making cooling machines for storing the catch of small-scale fishermen.

Abstract

Occupational accidents due to human errors in the operation of main engines on fishing vessels need to be considered because they can be fatal to the ship. This study aims to identify and analyze critical activities in the operation of fishing vessel main engines using the Systematic Human Error Reduction And Prediction Approach (SHERPA) method. The analytical method is to collect data by observation and interviews to fulfill the SHERPA tabulation. SHERPA analysis is closely related to using Hierarchial Task Analysis (HTA) diagrams to determine the amount of activity generated in the operation of fishing vessel main engines. In addition, work intensity analysis is applied to determine the stages that need to be considered in the operation of the main engine. Based on the resulting analysis, the highest work intensity is at the operating stage of the main engine. At the same time, the critical activity level is in closing the fuel faucet and the cooling system water faucet, which are included in the activity category of turning off the main engine. The findings of this study provide insight into handling critical activities in the operation of the main engine so that a strategy is needed to reduce human error in operation. The strategy for reducing this activity is strictly supervising and modifying or adding tools to make it easier for operators. The investigation results can inform the intensity and critical points of human error in the operation of fishing vessel main engines to reduce the occurrence of work accidents.

Abstract

Monitoring of diesel engine operational performance on fishing vessels recorded in real time based on microcontrollers is still rarely used. Monitoring of diesel engine operations is important to ensure the engine is in optimal performance as well as a consideration for predictive maintenance actions. This study aims to design and implement a real-time monitoring device based on microcontrollers. This device can measure and record RPM, temperature, and pressure data on diesel engines with good accuracy. Hall effect sensors for RPM, DS18B20 for temperature, and piezoresistive sensors for pressure are used, to maintain the right time it is equipped with RTC, SD card module for data storage, and Wi-Fi module for data access via the web. The test results show that this device is able to measure with good accuracy on each parameter with an average error of below 2%. When the operational parameters exceed the predetermined threshold, the device successfully gives an alarm as a critical sign. This study makes a significant contribution to the management and maintenance of diesel engines with real-time data and wireless access that increases efficiency and minimizes downtime due to operational failures

Abstract

This study aims to evaluate the utilization of used piston waste as an alternative material for making fishing boat propellers. Engineering is carried out to improve its mechanical properties by shot peening treatment. Shot peening is a surface treatment method by shooting small steel ball particles in a controlled manner. In this study, used pistons were recycled and used as the basic material for propellers, then shot peening was carried out with a pressure of 8 bar with variations in shooting duration for 5, 10, 15, and 20 minutes. Testing includes testing the chemical composition of the specimen, tensile testing, and observing the micro structure. Tensile testing is to determine mechanical strength, while macro photography is to identify changes in surface structure. The results of the chemical composition test state that the recycled piston is AL-Si-Cu. Meanwhile, the results of the tensile test show that the longer the shot peening duration, the tensile strength of the material increases significantly. Shot peening with a duration of 20 minutes gives the highest strength. The increase in tensile strength is 43% or 113 MPa compared to the non-treatment specimen. Micro structure observations show that the shot peening process creates a denser surface layer, so that tensile strength can be increased. This research is expected to be a reference for the propeller industry to increase production efficiency and sustainability.
