Abstract

Anatomy is the most essential course in health and medical education to study parts of human body and also the function of it.  Cadaver is a media used by medical student to study anatomical subject. Because of limited access to cadaver and also due to high prices, this situation makes it necessary to develope an alternative anatomical education media, one of them is the use 3D printing to produce anatomical models. Before 3D Print the cranium, it is necessary to do the segmentation process and often the segmentation result is not good enough and appear a lot of noises. The purpose of this research is  to optimize a 3D cranium based on DICOM (digital imaging and communications in medicine) data processing using the smoothing modules on 3D Slicer. The method of this research is to process the Cranium DICOM data using 3D Slicer software by varying the 5 types of smoothing modules. The results with default parameter fill holes and median have better results compared to others. Kernel size variations are performed for smoothing module fill holes and medians. The result is fill holes get optimal segmentation results using a kernel size of 3 mm and the median is 5 mm

Abstract

The vortex generator is one of the methods to improve heat transfer augmentation on flow characteristics in the air side of the fin and tube heat exchanger. There are some models of vortex generators to produce longitudinal vortices when the airflow passes the surface of the vortex generator. In the previous studies, the longitudinal vortices were able to reduce the wake region phenomenon behind the tube heat exchanger. This research aims to investigate the thermal performance of heat transfer on the collaboration between two models of vortex generators namely delta wing and winglet vortex generators on plate fin and tube heat exchanger. The simulation used four models (1) without the vortex generator (2) with the delta wing vortex generators (3) with delta winglet (4) with the combination of delta wing and winglet. The study was generated with computational fluid dynamics. The boundary conditions were set in the inlet as velocity and the outlet as pressure outlet. The airflow of velocity is represented by Reynolds numbers in the range of 4000 - 8000 with an interval of 500. The wall temperature of the tube is given at 400 Kelvin and the temperature of the airflow is given at 300 Kelvin. The epsilon model was used in the turbulence model of the simulation. The result explained that the thermal performance of heat transfer on delta winglets improved the airflow to induce longitudinal vortices and then reduced the wake region to improve the heat transfer coefficient more than other vortex generator models

Abstract

The Industrial Revolution 4.0 has produced many technologies that can increase productivity with various sophistications. Some of the technologies from the Industrial Revolution 4.0 are Cyber-Physical Systems (CPS), the Internet of Things (IoT), and also machines that are widely used today in 3D printing. 3D printing is related to reverse engineering, the process of remaking existing objects and creating digital documentation from existing objects. In this training, we introduced the concept of reverse engineering along with its workflow using 3D scanning and 3D printing technology. The aim of this training was that participants could gain inspiration and additional knowledge that can be used in companies to increase productivity and can also be used in the education sector to increase the knowledge of teachers. The method used in this training was divided into 2 sessions. The first was a seminar session to explain the theory and the second was a workshop session to practice the reverse engineering process directly. Hopefully, the results of this training could contribute to empowering companies, human resources, teachers, and students to have the skills and knowledge of the latest technology.

Abstract

Mechanical strength in weld joints is important in construction strength. This research takes the issue of SMAW weld joints strength when receiving bending loads on hopper products made from stainless steel 304. Two types of bending loads identified: root bend and face bend load. This research aims to obtain welding process parameters that are able to maximize the bending strength value of SMAW welding joints on stainless steel 304 material. Taguchi's experimental design uses current strength factors and electrode diameter, with an L8 (4121) Orthogonal Array. The novelty of this research is the use of response variables for root bend and face bend strength values which are optimized simultaneously. Multi-response optimization using Grey Relational Analysis method. The results of multi-response optimization are applied in confirmation tests to obtain actual results. The combination of a current strength of 65 A and an electrode diameter of 2.6 mm produces an optimal bending strength value with a desirability of 0.7475. These parameters produce actual face bend strength response of 1071.01 MPa (an increase of 5.38%) and a root bend strength of 1065.86 MPa (an increase of 17.36%).

Abstract

The aim of this research is to understand the characteristics of fins with a trapezoidal cross-section. The shape of the fin's cross-section is one of the influential factors affecting fin characteristics. In the design of fins, it is crucial to comprehend the characteristics of the fin as they relate to temperature distribution, heat transfer rate, and the efficiency of the fin. The research was conducted using numerical computation with an explicit finite difference method. Variations were made in the length of side 3 of the trapezium to 0 m, 0.02 m, and 0.04 m. The research results indicate that increasing the width of the fin enhances the temperature distribution, flow rate, and efficiency achievable by the fin. Significant improvement occurred when varying the side length from 0 m to 0.02 m, whereas subsequent variations did not considerably alter the efficiency. The highest efficiency achieved was 0.90 when the length of side 3 was 4 cm at the 300 seconds.

Abstract

The present study investigates the effect of the concentration of flexible resin on the dimensional accuracy of mixtures product manufactured by 3D printing using SLA technology. Specimens were designed and according to the ASTM D412 standard. Ten variations of resin mixtures were examined. The concentrations of the flexible resins were varied from 10% to 100%. Measurements of accuracy dimension were conducted on the fabricated specimens, and the average deviation was used to estimate the dimensional accuracy. The study reveals the least deviation in dimensions in the 10% flexible resin containing mixture and the highest in the 60% flexible resin containing mixture. The results explain the fabrication tendency of flexible resins in dimensional accuracy for 3D printing.

Abstract

As toddlerhood is a golden milestone during children's growth, high-protein foods like fish are strongly recommended to avoid stunting. On the other hand, a series of proper aeration is often required to support aquaculture in fish farming. Here, the technology of microbubble generators (MBG) can be properly applied. In the present work, subsequent activities which were carried out comprised the design manufacturing, installation, and also trial of MBG units, followed by site exposures. During the first exposure, two sessions covering a talk show and another practical work were conducted. The working principle of MBG was discussed in the first session, while the installation and operation were practically elaborated in the second session. Additionally, in the second exposure, several units of microbubble generators were granted to be applied to the community’s fish farming.

Abstract

Currently, the aviation industry is experiencing rapid growth, not only in manned aircraft but also in the development of Unmanned Aerial Vehicles (UAVs). One of the crucial components in UAVs is the propeller. Common manufacturing methods for propellers include forming, hand lay-up, and vacuum bagging. Alternative methods with promising potential include silicone molding and three-dimensional (3D) printing. This study aims to determine the most suitable manufacturing method for producing a propeller with a Clark Y airfoil type. The research was conducted using simulation, geometric analysis, and visual analysis. The silicone molding method can serve as an alternative to injection molding, as the dimensional difference between the CAD design and the final product is relatively minor, with the maximum shrinkage recorded at -8.77%. Meanwhile, the 3D printing method is more appropriate when the airfoil thickness is greater.

Abstract

In the present work, a simple aeration technology, utilizing the concept of a microbubble generator (MBG), was applied to an aquaculture field. It aims to support aeration by increasing the dissolved oxygen (DO) in the water. Subsequent supporting activities were carried out, comprising design, optimization and manufacturing, installation, and trials of MBG units, followed by site exposures. During one of the exposures, two sessions covering a discussion and another practical work were conducted. The working principle of the MBG was briefly explained in the first session, while the installation and operation were practically elaborated in the second session. Additionally, two units of MBG appliances were granted to be applied on the exposure site, namely Usaha Budidaya Ikan Senandung Betta. During the following exposure, the MBG implementation was evaluated through a series of DO measurements. Here, the measurement reached a range of 5.7 – 5.9 mg/L by operating the MBG. This means that the MBG increases the DO by around 1.5 mg/L.

Abstract

Over the years, technologies of 3D printing have enhanced the opportunity to ease the production of complex geometries. In particular, it further implies that the flexibility of materials is of a great importance. Therefore, the works covering studies of applicability on novel materials in rapid prototyping contribute to the development of additive manufacturing. The present work experimentally investigates a mechanical property, namely tensile strength, of 3D printing materials on the basis of the concentration of flexible-standard resins. Tensile strengths were obtained by a series of tensile tests. Here, the result reveals that the tensile strength monotonously decreases as the increase of the concentration of flexible resin’s concentration. Moreover, an ANOVA analysis strongly implies a consistent relationship between the tensile strength and the material’s mixture.
