Abstract

Natural fibers are increasingly used in various industries due to their eco-friendly properties and cost-effectiveness. However, current methods for testing the mechanical properties of these materials, such as tensile strength, often face limitations in accuracy and efficiency. This study aims to develop an innovative digital-based fiber tensile testing apparatus to enhance the precision of tensile testing. The research involves the design and construction of the apparatus, utilizing components such as ST37 steel, stepper motors, and Arduino technology. The apparatus was tested using two types of natural fibers, Cocos nucifera L. (coconut fiber) and Sansevieria, to assess their tensile properties. The results showed that although Sansevieria fibers have a smaller diameter, they exhibited higher tensile stress compared to coconut fibers. The developed digital testing apparatus enables more accurate and efficient fiber testing, contributing to the development of stronger and more sustainable materials for industrial applications. The findings of this study highlight the potential of advanced testing equipment in supporting the use of natural fibers in manufacturing and environmental sustainability.

Abstract

Komposit merupakan material yang terdiri dari dua kombinasi dua jenis bahan berbeda dimana tiap bahan tersebut memiliki sifat mekanik yang berbeda. Komposit yang diteliti dalam penelitian ini yaitu komposit serat yang menggunakan serat alam sebagai penguatnya dan resin epoxy sebagai matriks. Serat alam yang digunakan ada dua jenis yaitu serat sisal dan serat ijuk. Tujuan penelitian ini untuk mengetahui sifat mekanik komposit yang menggunakan serat sisal dan serat ijuk sebagai penguat. Sebelum dibuat menjadi spesimen uji, serat sisal direndam dalam NaOH 5% selama 4 jam dan serat ijuk dalam NaOH 5% selama 2 jam. Serat dalam komposit ini sebanyak 15% dari massa matriks kemudian persentase massa antara serat sisal dan serat ijuk dibagi menjadi tujuh variasi yaitu S15I0, S12I3, S9I6, S7.5I7.5, S6I9, S3I12 dan S0I15. Arah susunan serat yaitu serat lurus kontinu dan serat acak. Berdasarkan hasil penelitian ini, kekuatan tarik terbesar terdapat pada komposit variasi serat sisal 12% dan serat ijuk 3% (S12I3) dengan arah serat lurus kontinu yang memiliki kekuatan tarik rata-rata 115,01 MPa. Untuk kekuatan bending terbesar pada komposit variasi serat sisal 9% dan serat ijuk 6% ( S9I6) dengan arah serat lurus kontinu yang memiliki kekuatan bending rata-rata 123,83 MPa. Sedangkan kekuatan impak terbesar pada komposit variasi serat sisal 9% dan ijuk 6% (S9I6) dengan arah serat lurus kontinu yang memiliki energy impak rata-rata 20.71 kJ/mm2. Penelitian ini juga menunjukkan bahwa dengan adanya kombinasi anatara serat sisal dan serat ijuk dapat meningkatkan sifat mekanik komposit dan serat lurus kontinu memiliki sifat mekanik yang lebih baik dibandingkan dengan serat acak.

Abstract

Maintenance for machining and production facility is an important aspect to ensure a smooth production process. During this time, it was performed regular maintenance based on technical advice from supplier’s engines which just shows things in general without considering the actual operating conditions. This paper aims to plan the maintenance strategies for the Finish Mill unit based on reliability analysis by considering the target system reliability and cost of improving reliability. The data distribution obtained the most appropriate distribution. Based on the data obtained distribution parameters, then the function of the reliability of each part an be determined so that the value of the reliability of each part and the overall system for a specific time period can be calculated. The results showed that the failure or breakdown Mill Finish Unit was majority caused by the part of 561.BM1, 531.WF1, 531.BC6, 531.BC2, 531.BC1, 561.SR1 and 531.BC3. it means that need to focus o the reliability analysis to allocate their parts.

Abstract

Steel possesses mechanical properties that can enhance the hardness and microstructure of its surface, and heat treatment is one way to achieve these properties. This study aimed to investigate the impact of different cooling media on the heat treatment process and the resulting impact strength of S45C medium carbon steel. The steel specimens were heated at various temperatures (800oC, 850oC, and 900oC) in a furnace and then cooled using three different media: water, oil, and air. The study concluded that for all three temperatures, the specimens cooled with oil had the highest impact value. Furthermore, oil and air immersion resulted in ductile fractures, while water immersion caused brittle fractures.

Abstract

This article presents the design, fabrication, and testing of a hydraulic sheet metal bending tool. The main objective was to create a tool capable of bending sheets of various thicknesses, ranging from 2 to 4 mm, with high precision and minimal operator effort. The design incorporates a hydraulic ram for easy operation, allowing multiple plates to be bent in a short period of time. Key calculations, including bending force, spring load, and hydraulic force, are performed to ensure the efficiency and safety of the tool. Experimental results show that the tool is able to achieve the desired bending angles, with minimal spring return, and can handle up to three 10 cm wide sheets in approximately 10 minutes. The performance of the tool has been proven by tests, and the results confirm that it can meet the requirements of industrial sheet metal bending. Based on these results, the tool demonstrates its effectiveness in small and medium-scale operations, providing a cost-effective solution for sheet metal production.

Abstract

The maritime industry requires lightweight, strong, corrosion-resistant, and environmentally friendly materials, particularly for crewboat construction. Conventional metallic materials often suffer from corrosion, high weight, and elevated maintenance costs. This study investigates the mechanical performance of epoxy–jute fiber composite materials as a sustainable alternative for crewboat hull applications. Experimental laboratory testing was conducted using a quantitative approach to evaluate the tensile strength, flexural strength, impact resistance, and environmental durability of the composites. Specimens were fabricated using epoxy resin reinforced with jute fibers arranged in four different orientations (0°, 45°, 90°, and random) and tested according to ASTM standards. The results indicate that fiber orientation significantly influences mechanical properties. The 0° fiber orientation exhibited the highest tensile strength (89.04 MPa) and elongation (1.287%), indicating efficient load transfer and good ductility. The 45° orientation produced the highest flexural strength (39.14 MPa), while the random fiber orientation demonstrated the greatest elastic modulus (25.81 GPa) and impact resistance (6.409 kJ/m), providing superior stiffness and energy absorption. Seawater immersion tests showed no visible degradation in the composite structure. These findings suggest that epoxy–jute fiber composites have strong potential as eco-friendly crewboat construction materials, especially when applied using hybrid laminate configurations (0°/±45°/random) to optimize strength, stiffness, and impact resistance
