Abstract

The hydraulic system is a power transmission system by using the compressive energy of the fluid into mechanical energy to obtain a power greater than the initial power released. The press machine is one of the pieces of equipment that apply the hydraulic system. In the process of making laminated bamboo, the bamboo gluing technique is assisted using a press machine. Based on observations, the press machine used is a manual press machine, so the pressing process is not efficient. This study aims to increase the effectiveness of pressing laminated bamboo. The results of the study found that the press machine has 4 hydraulic cylinders so the pressing process can be carried out at several points simultaneously. The results of the hydraulic system analysis diagram show hydraulic cylinder moves in 16,9 seconds with a pressure of 100 bar, so the pressing process is fast. Mathematical calculations produce data, a hydraulic gear pump with a displacement of 13 cc/rev, electric motor power of 3,7 kW, hydraulic cylinder diameter of 63 mm, cylinder rod of 35 mm, rod of 400 mm, and a hydraulic tank capacity of 12 liters.

Abstract

The Vocational School Education is a university-level higher education program that places greater emphasis on practical fieldwork relevant to industry needs rather than academic theoretical knowledge. In Indonesia, vocational school programs or diplomas play a crucial role in the development and scientific research. The creation of a mini excavator model is a research and innovation project aimed at supporting students' practical training activities. The development of hydraulic swing components is used to enhance the components of the mini excavator model, which will later be expanded for educational purposes in the hydraulic drive system. The ultimate goal of this research is to manufacture hydraulic swing components that will be installed in the mini excavator model, with the final objective being to determine the pressure and rpm performance of these hydraulic swing components. Based on the conducted research, operating the mini excavator model requires a radius dimension or distance from the center point to the warning line of 3 m², and the maximum pressure for the mini excavator model is 150 kgf/cm², resulting in 11.17 rpm. Meanwhile, the allowable pressure for operating the hydraulic swing components in the mini excavator model is 100 kgf/cm², resulting in 8.54.

Abstract

A learning method is essential to achieve the existing curriculum standards. For success in the learning process, media or teaching aids are needed to enhance the process and learning outcomes related to students' levels of thinking (Suwardi et al., 2014). The mini excavator trainer serves as one of the solutions to support learning in hydraulic systems. The development of the hydraulic swing component is intended to improve the components of the mini excavator trainer, which will later be developed into a teaching aid for hydraulic drive systems. The ultimate goal of this research is to create a hydraulic swing component to be installed on the mini excavator trainer and, finally, to determine the pressure and RPM performance of the hydraulic swing component. Based on the research conducted, operating the mini excavator trainer requires a radius dimension or distance from the center point to the warning line of 3 m², with a maximum pressure of 150 kgf/cm² producing 11.17 RPM, while the allowable pressure to operate the hydraulic swing component on the mini excavator trainer is 100 kgf/cm², producing 8.54 RPM.

Abstract

The utilization of bamboo in architecture and construction as an eco-friendly alternative to wood is steadily increasing. While ovens are crucial tools in the production of laminated bamboo, particularly for heating during the bonding process, research on ovens specifically designed for bamboo lamination remains scarce. This study aims to optimize the design of laminated bamboo ovens using Computational Fluid Dynamics (CFD) simulations to achieve uniform heat distribution and maximize thermal efficiency. Three design iterations were tested: Iteration 1 with an air velocity of 4 m/s, Iteration 2 with 1.5 m/s, and Iteration 3 with 3 m/s. The results revealed that Iteration 1 exhibited uneven heat distribution, with initial temperatures reaching 1175 K before dropping sharply to 800 K. Iteration 2 showed slower initial heating, achieving a final temperature of 360 K, but heat distribution remained suboptimal. Iteration 3 delivered the best performance, achieving uniform and stable heat distribution near the target temperature of 473 K (200 °C). Overall, Iteration 3 demonstrated the most efficient thermal performance, not only meeting the target temperature with consistent heat distribution but also enhancing the overall heating efficiency of the oven.

Abstract

Bamboo is recognized for its eco-friendly attributes and rapid growth, serves as a promising sustainable alternative to wood. However, the high production cost of laminated bamboo remains a major challenge due to labor-intensive processes, particularly manual splitting, which affects efficiency and labor costs. To overcome this issue, this study presents an automated bamboo diameter measurement system that leverages Canny Edge Detection and Hough Transform to ensure precise and uniform slat dimensions. A dataset of 100 bamboo images with diameters ranging from 11 - 13 cm was utilized for training and testing. The system achieved a high accuracy, with a coefficient of determination (R²) of 0.973, demonstrating strong predictive reliability. Furthermore, Bayesian Optimization was applied to fine-tune parameters, resulting in an optimized configuration for both Canny Edge Detection and Hough Transform. The proposed system reduces dependence on manual labor, thereby lowering production costs and improving overall manufacturing efficiency. Automation in the bamboo splitting process ensures consistent and precise slat dimensions, supporting scalability and enhancing the economic feasibility of laminated bamboo production. The findings of this study provide a practical and sustainable solution to optimize production, making laminated bamboo a more viable and competitive material in the industry.

Abstract

Laminated bamboo is an engineered composite product made from dried and bonded bamboo strips, offering high potential as an eco-friendly material for construction and furniture applications. One of the critical steps in its production process is the drying of bamboo strips, which aims to reduce moisture content and prevent mold, cracking, and delamination. This study aims to design an energi-efficient bamboo strip drying system to enhance the productivity of the laminated bamboo industry. The system design includes a modular drying chamber, a boiler-based heating system with a centrifugal blower, and corrosion-resistant materials such as stainless steel SS304. Thermal energi demand was calculated using convection heat transfer and total thermal resistance approaches, resulting in a required energi of 212240.42 kJ to dry 250 bamboo strips per cycle in an hour. Computational Fluid Dynamics (CFD) simulations indicate uniform temperature and airflow distribution inside the drying chamber. The thermal efficiency of the system reaches 97.4%, indicating its suitability for industrial application. These findings provide a foundation for developing standardized, efficient, and sustainable bamboo drying systems.

Abstract

Penggunaan mesin pembelah bambu dalam produksi bambu laminasi adalah untuk mengubah batang bambu menjadi bilah-bilah bambu. Pada mesin pembelah bambu di Rosse Bambu Yogyakarta terjadi kerusakan komponen yaitu patahnya poros track roller bearing. Poros mengalami mekanisme patah getas yang disebabkan oleh ketidaksesuaian pemilihan material. Diketahui bahwa poros yang patah terbuat dari baja karbon tinggi AISI 1080 yang telah melalui proses quenching. Poros track roller bearing dari mesin pembelah bambu diharapkan memiliki ketahanan impact yang tinggi namun juga harus memiliki nilai kekerasan yang sesuai dengan standar nilai kekerasan poros. Dengan memilih material substitusi yang ideal untuk poros dan mengidentifikasi proses perlakuan panas yang tepat untuk mendapatkan sifat material yang diinginkan, proses yang efektif dapat diketahui untuk meningkatkan masa pakai poros track roller bearing dan mengurangi potensi terjadinya kegagalan serupa. Tujuan dari penelitian ini adalah untuk mengetahui temperatur tempering optimum yang dapat dilakukan terhadap baja VCN 150 sebagai material substitusi poros track roller bearing pada mesin pembelah bambu. Pada penelitian ini proses perlakuan panas dilakukan dengan memanaskan spesimen uji pada temperatur 850 °C dalam tungku selama 1 jam kemudian dilanjutkan dengan quenching dengan media oli. Setelah quenching, dilakukan tempering pada temperatur 200 °C, 300 °C, dan 400 °C selama 1 jam kemudian dilanjutkan dengan pendinginan di udara bebas. Pengujian yang dilakukan meliputi uji struktur mikro, uji kekerasan Vickers, uji impact Charpy, dan analisis fraktografi menggunakan Scanning Electron Microscope pada permukaan patahan hasil uji impact. Hasil pengujian menunjukkan bahwa spesimen yang melalui proses tempering pada temperatur 400 °C memberikan hasil optimum dengan nilai kekerasan sebesar 359,92 HV dan harga impact sebesar 1,37 J/mm ².

Abstract

As the solidification reaches the hot spot area, no molten metal remains and shrinkage is formed. To anticipate the shrinkage, a riser is added to the casting system. An optimal riser design would produce free shrinkage components. One of the factors that affect riser efficiency is the riser shape. This study aims to find the most efficient side riser shape by using simulation software. The riser shape of tubes, tubes with a half sphere on top, hemispheres, conical tubes, tubes with an oval cross-section, and cubes are used in this experiment, with the volume of all risers kept constant. The most efficient shape of the riser is the tube. The tube riser produces a larger modulus. The tube riser generated directional solidification. The same pattern can be seen in the niyama criteria and solidification temperature, where the tube riser has a more continuous pattern compared to other riser shapes.
