Abstract

Composites are a combination of matrix or binder materials with reinforcement. The combination will produce a composite material that has different mechanical properties and characteristics from the constituent material, so that a desired composite material can be planned. The abundance of natural resources of palm fiber from palm trees but its utilization is still lacking, due to the mechanical properties of this fiber which is still in doubt about its reliability. For this reason, it is necessary to conduct research on epoxy resin composites with fibers as a filler so that the mechanical properties of each fiber and matrix composition can be known. The study used an experimental method that began with the manufacture of composite materials for the test specimens using an epoxy resin matrix reinforced with fibers with fiber volume fraction variations of 0%, 5%, 7% and 9%. Testing the mechanical properties of composite materials, which in this case is testing the torsional strength and impact strength of composite materials with variations in some fiber content, is then carried out simulations using the test data. The results of this study obtained an optimum average impact strength of 13.00 kJ/m on a composite material with a fiber content of 9% and obtained an optimum torsional strength with an average torque value of 271.14 N.m and an average stress value. shear of 2698.48 MPa on a composite material with a fiber content of 9%. The data obtained shows that the higher the percentage of fiber used, the greater the impact strength and torsional strength produced by the fiber-reinforced composite material.

Abstract

Corrosion of carbon steel frames is a major concern in the automotive industry, especially for motorcycles that are often exposed to harsh environments. As an eco friendly alternative to synthetic chemical-based corrosion inhibitors, this study evaluates the effectiveness of corn husk extract as a natural, tannin-based inhibitor. Corn husks were selected due to their abundant availability as agricultural waste and their active compounds with potential anti-corrosion properties. The extract was obtained using maceration, reflux, and ultrasonic methods, and tested in corrosive solutions of NaCl, HCl, and H₂SO₄. The inhibitor’s effectiveness was assessed using weight loss measurements and surface morphology analysis. Results showed that corn husk extract reached up to 100% inhibition efficiency at a 600 ppm concentration, particularly in NaCl solution. The tannins and phenolic compounds in the extract played a crucial role in forming a protective layer on the carbon steel surface. These findings highlight the strong potential of corn husks as a green base material for corrosion inhibitors, while also promoting the use of biomass waste in developing sustainable corrosion protection technologies for the automotive industry.

Abstract

Climate has a significant influence on nearly all aspects of plant growth, including that of citrus plants. To overcome the uncertain environment, a reliable irrigation system is essential in citrus gardens, with optimization achieved through the use of an automated irrigation system. The engineering of this automatic citrus garden fertilization irrigation system is carried out in groups on citrus plants using a photocell timer and PVC stop valve on each plant group path to facilitate maintenance and repairs if damage occurs to the automatic irrigation system without disrupting the main pipe irrigation system and other plant groups. This automatic irrigation system, in the driving engine and sprayer pump section, utilizes a machine and a sprayer pump with spare parts readily available in each region, thereby facilitating maintenance and repairs as needed. The machine and sprayer pump function to pump water and fertilizer that have previously been mixed in the mixing tank. Then the water and fertilizer will be distributed through the main pipe distribution line and the fertilization system pipe in groups using ½ inch PVC pipes and using a sprayer hose to the citrus trees. Engineering an automatic citrus fertilization irrigation system and processing carried out in groups on citrus plants will speed up the work of farmers in the garden, so that it can be more effective and more efficient, and save labor

Abstract

Strength Analysis of Straight (Vertical) Pipe Connections Using Modified Flange on Deep Well Pump Pipe Installation is an important part of the oil and natural gas industry, because it functions to drain fluid from the well to the oil gathering station. Well pump pipelines must be well designed to ensure safety and operational efficiency. One of the important components in the well pump pipeline design is the straight (vertical) pipe connection using a modified flange. The strength analysis of this straight pipe connection is carried out to determine how the modified flange affects the strength of the pipe connection. The method used is a design analysis of the strength of straight pipe joints using modified flanges with reference to international codes and simulations using Solidworks software. The results show that the flange must be modified because it is for the cable line and adjusts to the diameter of the well which is 8' in diameter. The strength of straight pipe joints is also affected by pipe diameter, operating pressure, and pipe material type. The conclusion of this analysis is that the modified flange can reduce the strength of the straight pipe connection, so it requires proper consideration and calculation. Therefore, the modified flange should be considered in the well pump pipeline design to ensure safety and operational efficiency

Abstract

Abstract-- Corrosion is a significant factor that decreases the performance and service life of motorcycle components, especially exhaust pipes that are directly exposed to the environment. This study aims to analyze and compare the corrosion rate of factory-made motorcycle exhausts when exposed to two corrosive media: a 3.5 wt% sodium chloride (NaCl) solution and natural seawater. An immersion test was conducted under laboratory conditions for seven days (168 h) using eight AISI 1010 coupons (2 × 2 cm). Four specimens were immersed in seawater, and four in 3.5 % NaCl. After pickling, each coupon was weighed, immersed, cleaned, and re-weighed. Mass loss was converted to a corrosion rate using the gravimetric method and expressed in millimeters per year (mm· year¹). The average corrosion rate in seawater was 4,121.9 mm/year, whereas in 3.5% NaCl it was 71.7 mm/year. The significantly higher rate in seawater is attributed to additional ions, such as magnesium, calcium, and sulfate, that accelerate electrochemical reactions. These findings underscore the importance of adequate surface protection for exhaust pipes, particularly for motorcycles operating in coastal or high-humidity environments, and serve as a basis for developing corrosion-resistant materials or coatings for automotive components.
