Abstract

Bucket teeth are an important component of an excavator that functions as a material penetrator or digger. This part is prone to failure because it is in direct contact with the ground. This study aims to determine the value of stress, strain, deformation, and safety factors that occur in the Komatsu PC400 excavator bucket teeth against thickness variations of 2.5 mm, 5 mm, 7.5 mm, and 10 mm. This study uses a computer with specifications: processor: Intel (R) Celeron (R) N4000 CPU @ 1.10 GHz, memory: 8 GB. Windows 10 Home Single Language 64-bit Operating System. This computer is equipped with Autodesk Inventor Professional 2023 and ANSYS Workbench R1 2023 software. The method used in this research is a testing method using ANSYS software with a finite element method approach, namely static structural. The simulation results of bucket teeth show the maximum deformation values are 0.16382 mm, 0.13832 mm, 0.1249 mm, and 0.11619 mm, respectively. Furthermore, the maximum equivalent stress values are 108.6 Mpa, 79.712 Mpa, 80.338 Mpa, and 79.992 Mpa, respectively. For the equivalent elastic strain maximum, 0.00052993, 0.00038899, 0.000392, and 0.00039029 were obtained. Then the safety factor value is obtained 3.8214, 5.2062, 5.1657, and 5.188. This shows that the thicker the thickness variation, the better the strength value.

Abstract

The process of making cement goes through numerous phases and different procedures in order to produce cement that is up to factory requirements. In addition to the combustion process, the cooling process also exists in the cement manufacturing kiln area, particularly the rotary kiln, but it is less crucial. A crucial aspect of the cement production machinery is the cooling procedure or clinker cooler. The cooling process here impacts the quality of the cement produced, therefore this equipment is used to cool or lower the temperature of the clinker so it doesn't burn in the rotary kiln. The relationship between the clinker's crystal concentration and the liquid phase is influenced by the rate at which the clinker cools

Abstract

This research focuses on manufacturing composite wings using the vacuum bag process. The vacuum bag method is used because it can reduce manufacturing time and improve the quality of the final product. This study aims to determine the impact of the vacuum bag method on the geometry between the design stages and the final results of the UAV wing. Differences in design geometry and final results are calculated by measurement. The effects of variations in thickness and loading were estimated by modeling simulations with Fusion360 Software. The geometry of the design stage and the final result did not have a significant change, with a difference of 10% in thickness, 2.45% in wing length, and 0.80% in wing width. For deformation, it can be concluded that the increase in thickness and loading is directly proportional to the magnitude of the deformation that occurs. The greater the value of thickness and loading, the greater the deformation that occurs.

Abstract

To create briquettes, the raw materials are compressed using a variety of pressing pressures. Briquette presses come in two popular varieties: vertical and horizontal. Briquettes are often made from non-hazardous home waste and agricultural biomass, offering a premium and sustainable alternative energy source. The goal of this study was to use a hydraulic press-type briquette press method to improve the shape properties of the briquettes. The ingredients employed in this investigation were water, tapioca, wood dust, and rice husk. The composition of the briquettes is 40% rice husk, 40% sawdust, 10% tapioca, and 10% water. A hydraulic press machine with a maximum pressure of 30 Psi was utilized in the briquette press method. This study will examine each mold's density, drop test, water resistance, and burning rate. According to this study, triangular briquettes have the lowest briquette burning rate value (0.1 g/min), the lowest impact resistance value (0.67%), the slowest burning rate value (0.1 g/min), which indicates longer burning, and the highest value (0.9696 g/cm³), which indicates a denser and more solid structure. According to the findings of the test criteria that researchers have conducted, triangular briquettes are recommended.

Abstract

The lack of a regular maintenance schedule system and millennial farmers' lack of knowledge about maintaining tobacco shredding machines are the issues facing Nahdlatul Ulama (NU) in Magelang.  This scenario results in less than ideal shredded quality and frequent machine failures.  Enhancing farmers' knowledge and proficiency in maintenance, repair, and information technology use for scheduling machine maintenance is the aim of this community service project. The implementation approach consists of training in the use of basic digital programs to record and arrange maintenance schedules, hands-on machine maintenance and repair practice, and teaching through the supply of materials.  Thirteen ladies and seventeen males made up the 30 participants in the exercise. With participants' average comprehension rising from 22% prior to the activity to 86% following it, the outcomes discussed shown a notable improvement. It has been demonstrated that machine maintenance results in finer and more consistent shredded tobacco, and the application of information technology facilitates efficient and sustainable scheduling for participants.  The community service project was successful in enhancing the quality of the shredded output, maximizing machine performance, and motivating millennial farmers to be more flexible when it comes to using information technology in tobacco farming.

Abstract

Briket biomassa merupakan salah satu sumber energi terbarukan yang potensial, namun kualitas briket sangat dipengaruhi oleh mekanisme densifikasi dan orientasi gaya tekan yang dihasilkan oleh mesin pencetak briket. Penelitian ini bertujuan untuk menganalisis pengaruh desain mesin pencetak briket tipe vertikal dan horizontal terhadap karakteristik fisik dan mekanik briket biomassa. Penelitian dilakukan secara eksperimental dengan pendekatan komparatif menggunakan campuran biomassa berupa arang sekam padi (40%), arang serbuk kayu (40%), perekat tapioka (10%), dan air (10%). Mesin pencetak tipe vertikal menggunakan sistem pemadatan pneumatic-hydraulic dengan variasi tekanan sebesar 206.842, 344.738, 482.633, dan 620.528 Pa, sedangkan mesin tipe horizontal menggunakan mekanisme screw press yang digerakkan motor listrik 1,5 HP dengan diameter screw 6 cm, panjang screw 26 cm, dan kapasitas produksi 200 kg/jam. Tekanan pemadatan pada mesin horizontal tidak dapat dinyatakan sebagai satu nilai tetap seperti pada mesin vertikal karena mekanisme screw press menghasilkan tekanan dinamis yang berubah secara kontinu selama proses pencetakan. Kualitas briket dianalisis berdasarkan densitas, ketahanan mekanik (drop test), water resistance index (WRI), dan laju pembakaran. Hasil penelitian menunjukkan bahwa peningkatan tekanan pemadatan pada mesin vertikal mampu meningkatkan densitas briket dari 0,551 menjadi 0,731 g/cm³ serta menurunkan persentase kerusakan drop test dari 45,15% menjadi 18,51%. Selain itu, laju pembakaran menurun dari 0,215 menjadi 0,158 g/menit yang menunjukkan terbentuknya struktur briket yang lebih padat dan stabil. Mesin horizontal menghasilkan densitas rata-rata sebesar 0,654 g/cm³ dengan laju pembakaran sebesar 0,175 g/menit serta menunjukkan variasi struktur yang relatif lebih besar. Hasil penelitian menunjukkan bahwa orientasi gaya tekan vertikal menghasilkan distribusi tekanan yang lebih merata dan proses densifikasi biomassa yang lebih efektif sehingga menghasilkan briket dengan kekuatan mekanik dan kestabilan pembakaran yang lebih baik. Penelitian ini memberikan kontribusi ilmiah dalam menjelaskan hubungan antara orientasi gaya tekan, mekanisme densifikasi, dan kualitas briket pada sistem pencetakan biomassa.

Abstract

The use of excavators across industrial and mining sectors is critical, particularly for bucket tooth components that perform penetration and excavation. These components often undergo wear and tear due to repeated stress and abrasion. This study aims to analyze the influence of variations in bucket tooth notch types on stress, strain, deformation, and safety factors using the Finite Element Method. The variation of standard, elliptical, and diamond notch types in the Komatsu PC200 bucket tooth model was designed using Autodesk Inventor Professional 2025. The simulation results show that the elliptical notch type has a maximum stress value of 6.2893 MPa, a maximum strain of 0.000036465 ul, and a maximum deformation of 0.00266049 mm, which is better than the standard and diamond types. Meanwhile, the diamond type has the highest maximum stress of 7.8416 MPa and the lowest deformation of 0.00259299 mm. The highest safety factor was found in the elliptical type (6.91635), which indicates that this design is safer to use in heavy workload conditions. The results of this study show that the elliptical notch type design is more efficient and has the best resistance to workload, so that it can improve the service life and performance of bucket teeth. The applied load represents a static reference for comparative evaluation among geometries; therefore, the results reflect relative design performance.
