Abstract. Brake pads are a crucial component of brake parts, especially for motor vehicles. Regulations restricting the use of asbestos have prompted researchers to seek alternatives. In this study, brake pads will be made using biomass waste from sawdust obtained from the activities of furniture MSMEs in the Bangkinang area, Kampar, Riau. The utilization of this biomass waste is intended to minimize waste volume and provide an alternative raw material and production process for brake pads that are low-cost and abundantly available. In this study, brake pads are made with a mixture of sawdust filler matrix and epoxy resin reinforcement matrix. Next, the brake pad samples will be tested for physical characteristics in the form of density and water absorption. Mechanical strength is tested through a bending test using the Universal testing test. Brake pad performance will be tested through wear test values. The results of the test on physical and mechanical properties obtained a density of 0.73 g/cm3, a maximum bending load of 452.67 N, a flexural strength of 187.97 MPa, and an elastic modulus of 184.69 MPa. The physical characteristics of this composite show that sawdust can be an alternative raw material for brake pads that is cheap and abundantly available, thus supporting environmental sustainability.

Piping systems are critical components across various industrial sectors, including agriculture. The 90° elbow plays a key role in directing fluid flow; however, abrupt changes in flow direction within the elbow often lead to pressure losses and vortex formation, particularly in configurations with small curvature radii. This study aims to analyze the fluid flow characteristics within a 90° elbow under different curvature radii (extreme, R30 mm, and R50 mm) and various valve opening conditions, using numerical simulation based on Computational Fluid Dynamics (CFD) in ANSYS Fluent 2019 R3. The simulation results show that increasing the curvature radius leads to a more uniform pressure distribution along the bend and a reduction in vortex formation. Although larger valve openings increase flow velocity and Reynolds number, the pressure and velocity contours do not exhibit significant changes in flow patterns. This study confirms that elbow geometry design greatly influences the hydrodynamic efficiency of piping systems and can help minimize the risk of damage due to uneven pressure distribution

Abstract. This research was conducted at PT. Yamatogomu Indonesia with a focus on the I49 Injection machine that experienced high downtime. The objective of the research was to analyze the causes of machine failure and design an appropriate maintenance strategy. The method used was Reliability Centered Maintenance (RCM) supported by Failure Mode and Effect Analysis (FMEA) and Logic Tree Analysis (LTA). The FMEA results identified five main failure modes with a total Risk Priority Number (RPN) value of 702. The top three modes, namely no heat or excessive heat, no vacuum motor pressure gauge indicator, and compound puller motor malfunction, contributed 76% of the total risk. Based on LTA, all failure modes were classified as evident and did not have a direct impact on safety, but could disrupt operations. The maintenance strategies implemented consisted of Condition Directed (CD), Time Directed (TD), and Failure Finding (FF), with the majority of actions (60%) being CD. These results can be the basis for developing a more effective maintenance schedule to minimize downtime and increase production efficiency.

Abstract. The increasing demand for eco-friendly and recyclable materials has driven the development of natural fiber-based composite materials. This study aims to analyze the effect of volume fraction variation on the mechanical properties of hybrid composites made from coconut coir fiber and banana stem fiber with an epoxy matrix. The research employed an experimental method with variations of fiber volume fractions at 40%, 30%, and 20%, and mechanical testing including tensile, bending, and impact tests based on ASTM standards. The results showed that the highest tensile strength was achieved by the composite with a 60% matrix and 40% fiber volume fraction, reaching 21.16 MPa. Meanwhile, the highest bending strength and impact resistance were obtained by the composite with an 80% matrix and 20% fiber volume fraction, at 49.46 MPa and 0.00837 Joule/mm², respectively. Increasing the fiber content tends to enhance tensile strength but reduces bending strength and impact resistance due to uneven resin distribution and the formation of voids. This hybrid composite has potential as an environmentally friendly material alternative with competitive mechanical properties.

Geographically and demographically, Indonesia has natural conditions that have the potential for floods disaster. There are at least 16,771 islands and 65,017 rivers that fill the archipelago. Unfortunately, the ever-increasing urban population accompanied by a lack of awareness and preparation for protecting the environment has resulted in a higher risk of flooding in urban areas. This study utilizes digital imagery to detect flood conditions in urban areas. In terms of access, digital images are available in urban CCTV monitoring systems as well as office areas, housing, and from people who have smartphones. The detection method used in this study is the VGG19 model which consists of 16 convolution layers and 3 standard classification layers. All convolution layers are divided into 5 blocks followed by a MaxPooling layer for each block to reduce the resolution of the input image. In the last layer, SoftMax layer is used to estimate the probability between flood labels and normal conditions. There are 4 parameters that were optimized during the VGG19 model training process, namely Batch Size, Learning Rate, Dropout and Epoch (training repetition). To test the proposed model, public datasets are used, namely the Roadway Flooding Image Dataset and Road Vehicle Images Dataset. The best flood detection results (or normal conditions) achieve the accuracy of 98.78%. As for the other three performance metrics, namely precision, recall and F1-score, they reach 99%. These results are generated by the VGG19 model with a Batch Size parameter of 20, a Learning Rate of 1e-5 (0.00001), 50% Dropout and 100 Epoch. The achievement values of the four metrics can be considered quite good, so that the VGG19 model has the opportunity to be developed for flood detection applications in order to monitor urban flood conditions.
