Abstract

Splitting merupakan salah satu tahapan proses produksi bambu laminasi. Splitting dilakukan dengan mesin pembelah bambu untuk mengubah batang bambu menjadi bilah-bilah bambu. Dalam proses splitting, komponen booster bergerak maju-mundur di sepanjang rel untuk mendorong bambu yang terletak pada bagian penopang sampai ujung bambu bertumbukan dengan pisau pembelah sehingga batang bambu terbelah menjadi bilah-bilah (bamboo strips). Pada mesin pembelah bambu terdapat track roller bearing yang berfungsi sebagai guide roller. Salah satu komponen penting dalam rangkaian track roller bearing adalah poros. Kasus kegagalan komponen berupa patahnya poros track roller bearing telah dijumpai pada mesin pembelah bambu yang terdapat di sentra kerajinan bambu, Rosse Bambu Yogyakarta. Kerusakan komponen mesin tentu menghambat berjalannya proses produksi bambu laminasi, oleh sebab itu dilakukan analisis kegagalan dalam penelitian ini dengan tujuan untuk mengetahui faktor penyebab kegagalan yang dialami oleh poros track roller bearing pada mesin pembelah bambu sekaligus sebagai upaya antisipasi untuk menghindari terjadinya kasus kegagalan yang serupa. Analisis kegagalan dilakukan dengan melakukan pengujian komposisi kimia material dengan metode Atomic Emission Spectroscopy (AES), pengamatan visual dan pengamatan skala makro terhadap permukaan patahan yang terbentuk, pengujian metalografi untuk mengetahui struktur mikro material poros track roller bearing yang patah, dan pengujian kekerasan Vickers. Permukaan patahan poros tampak terang dan berbentuk granular menunjukkan karakteristik patah getas. Hasil analisis menunjukkan bahwa material poros terbuat dari baja karbon tinggi AISI 1080 yang telah menerima perlakuan quenching dengan nilai kekerasan material sebesar 311,59 HV sehingga material bersifat keras dan getas. Sifat tersebut mengakibatkan poros tidak mampu menahan beban kejut yang diterima saat proses pembelahan bambu berlangsung. Kesimpulan yang diperoleh yaitu kegagalan yang terjadi disebabkan oleh faktor pemilihan material dan perlakuan panas yang dilakukan tidak sesuai untuk aplikasi poros track roller bearing pada mesin pembelah bambu.

Abstract

Carbon emissions from diesel engines, particularly those from heavy equipment, are a significant greenhouse gas emitter in industries such as construction, mining, and logistics. As global efforts toward decarbonization intensify, carbon capture technologies offer a solution to reduce global emissions. This paper conducts a literature review to explore current carbon capture technologies—including chemical sequestration, physical sequestration, and membrane separation—and evaluates their potential for integration with heavy equipment exhaust systems. Key considerations include system size, energy requirements, maintenance, and operational compatibility. Integration of exhaust heat recovery systems is also assessed as a complementary solution to address the high energy demands of carbon capture in the environment. Technical, economic, and regulatory challenges are discussed, along with potential innovations and use cases that could support future deployments. The findings indicate that although carbon capture is still in its infancy, targeted applications and modular designs supported by policy incentives could enable practical implementation in the near future. This review provides a foundation for future research, pilot projects, and system designs aimed at enabling sustainable operation of heavy equipment

Abstract

Most laminated bamboo production processes in small and medium-sized industries still rely on cold pressing, which requires long pressing times and often results in inconsistent bonding quality. This study aims to design a hot press machine by integrating a hydraulic pressing system, an electric heating system, and temperature distribution analysis using Computational Fluid Dynamics (CFD). The pressing system employs four hydraulic cylinders with a capacity of 15 tons and a maximum operating pressure of 110 bar, while the heating system requires 5.13 kW of power. CFD simulation results indicate a relatively uniform temperature distribution across the primary heating zone, although temperature gradients occur near the edges due to heat loss and the low thermal conductivity of bamboo. The proposed design satisfies the technical requirements of the laminated bamboo manufacturing process and has the potential to improve pressing uniformity and product quality, providing a foundation for the development of hot press machines for small- and medium-scale laminated bamboo industries.

Abstract

The hydraulic system plays a vital role in supporting excavator performance by transmitting power through pressurized fluid to actuate the boom, arm, and bucket. However, fluid leakage can significantly reduce operational efficiency and performance. This study aims to analyze the hydraulic system performance of the Zhugimada mini excavator trainer unit before and after repair. Tests were conducted on three main parameters: silinder drift, silinder speed, and silinder pressure, under three load conditions zero capacity, struck capacity, and heaped capacity. The results show that leakage was caused by damage to the fittings on the arm and bucket silinders, the seal on the boom silinder, the valve connecting the tank and pump, and an electric motor speed exceeding the standard (1,491 rpm). The leakage impact was indicated by a decrease in silinder speed 1.41% for the boom, 1.34% for the arm, and 0.51% for the bucket and a 16.28% pressure drop in the boom under no-load conditions. After the repair, system performance improved significantly, with boom speed increasing by 0.92%–2.04% and arm speed by 0.82%–1.77%. The repair effectively addressed both internal and external leakage and improved the overall efficiency of the hydraulic system.

Abstract

The use of electric road sweeper waste sweeping vehicles can increase effectiveness in waste management. This electric road sweeper research aims to integrate the hydraulic system of the sweeper arm and the double cylinder vessel. The process of designing a hydraulic system diagram uses FluidSIM 4.2 software and carries out mathematical calculations based on collecting data directly in the field. The test results show that when the vessel is unloaded, the movement of the sweep arm hydraulic cylinder when extending is 4.20 m/s and the retract movement is 3.1 m/s, and the movement of the vessel hydraulic cylinder when extending is 11.77 m/s and the movement retract worth 9.4 m/s. When the vessel was given a load of 100 kg, the test results obtained were that the movement of the hydraulic cylinder of the sweep arm during extend was 4.20 m/s and the retract movement was 3.1 m/s, as well as the movement of the vessel's hydraulic cylinder in both extend movements was 12.30 m/s. s and a retract movement of 8.60 m/s. It can be seen based on the results of the tests carried out that the load on the vessel influences the movement speed of the vessel's hydraulic cylinder, this is caused by the influence of gravity.

Abstract

The electric road sweeper developed by the Mechanical Engineering Department of the Gadjah Mada University Vocational School can handle waste management problems. To improve sweeper performance, several changes are still required in the unit, especially in the sweeper vessel section. In an effort to improve sweeper performance, vessel design is needed. Design and performance analysis of vessels using Autodesk Inventor software. In this research, the addition and replacement of hydraulic cylinder types was carried out to make it a transport vehicle. Apart from that, the use of lighter materials also reduces the weight of the vessel from 650 kg to 278.95 kg. The simulation results show that all vessel sweeper components have a safety factor above one, indicating that they are safe to use. Apart from that, this design is able to withstand loads of up to 4900 N without exceeding the yield strength limit of the material used by the vessel. The maximum inclination of the sweeper vessel is 30.4 degrees. Hydraulic cylinder testing shows an extend speed of 11.77 m/s and a retract speed of 7.9 m/s. Under 100 kg load conditions, the extend speed becomes 12.49 m/s and the retract becomes 8.39 m/s, the retract movement is faster due to gravity.

Abstract

Based on field observations, the exhaust brake component on the Hino 500 FM 260 JD unit frequently experiences breakdowns. One of the primary causes of failure is the ingress of mud into the exhaust chamber, which disrupts the functionality of the component. This study aims to compare the performance of exhaust brake components with and without a protective cover to enhance their lifetime, analyze the failure rate, and calculate the potential lost cost associated with exhaust brake failures in hauling units. Data collection was conducted directly in the field, and protective covers were installed on three dump truck units in the hauling fleet. The test results indicate that when the exhaust brake component was used without a cover, 14 failures were recorded, whereas with the cover installed, only 4 failures occurred. These findings demonstrate that the protective cover significantly impacts the lifetime and failure rate of the exhaust brake component. Following the testing phase, a potential lost cost analysis was conducted, considering four cost variables: spare parts, production losses, operator costs, and mechanic costs.

Abstract

This research aims to optimize consumable goods inventory control for dotting gloves items in a heavy equipment company. The inventory control process uses mathematical calculation methods, namely additional inventory (buffer stock) and reorder points as well as designing a web-based inventory application system. The research results showed that stock outs occurred repeatedly for dotting gloves. In 2023, the initial inventory of this item will be out of stock for 4 months. The frequency of purchasing dotting gloves is relatively small, only done twice in 5 months. After calculating the buffer stock and reorder point, the company is advised to place a reorder when the stock of dotting gloves reaches 83 pairs or 7 dozen to maintain the continuity of the company's operations. Next, a web-based inventory management application was created to automatically detect reorder points on dotting glove items.
