Abstract

Purpose: In the composition of a pop song entitled Senja, cultivators were inspired to create a pop music composition using the help of MIDI sequencer and audio effect processor. MIDI and Sequencer are two different things but can work together with each other that can be used in the recording process or the production and presentation of a work of music. Research method: The ability to compose ideas and be able to hear audio replayed quickly allows composers to experiment with the files. Results and discussion: Because MIDI is a collection of commands that make sound, MIDI circuits can be manipulated in a variety of ways that audio pre-recordings cannot. Implication: In the process of making this final task, the cultivator decided to pour his personal experience (internal) into a song called Senja. It is applied to a pop music composition played by 5 people (Quintet Performance) with the help of MIDI Sequencer.

Abstract

Musik merupakan suatu hasil karya seni  berupa bunyi dalam bentuk lagu atau komposisi yang mengungkapkan pikiran dan perasaan penciptanya melalui unsur-unsur pokok musik yaitu irama, melodi, harmoni, dan bentuk atau struktur lagu serta ekspresi sebagai suatu kesatuan. Musik  itu sendiri tercipta karena adanya proses kreativitas dari penciptanya, yang meliputi aspek pengalaman, sumber refrensi ataupun jurnal ilmiah. Dalam proses menciptakan suatu komposisi musik, tentunya harus ada pemilihan ide dan konsep yang jelas. Kata cloning menginspirasi ide, konsep dan judul ke dalam karya ini. Kloning sendiri berasal dari kata bahasa Inggris cloning yang berarti suatu usaha untuk  menciptakan duplikat suatu organisme melalui proses aseksual. Setelah membaca buku “Kloning: Kemungkinan Teknis dan Implikasi Permasalahan Sosial-Etisnya,”menginspirasi terbentuknya karya Cloning yang mengangkat bentuk musik minimalis dengan perpaduan teknik drone, ostinato, rhythmic displacement, dan layering. Proses kreativitas dalam pembuatan karya ini memiliki beberapa kendala baik dari pemilihan instrument maupun pemilihan melodi, chord, dan ritmis. Hal tersebut merupakan sebuah proses yang dilewat sehingga bisa menghasilkan karya dengan baik sebagai hasil akhirnya.

Abstract

This paper proposes a mathematical correlation between styrene butadiene rubber (SBR)-butadiene rubber (BR) composition and hyperelastic model parameters for numerical studies in vehicle tire design. Experimental, numerical, and curve-fitting methods were employed in this research. Experimental tests were conducted using tensile tests for SBR-BR. The numerical study of the SBR-BR tensile test was carried out using several classic hyperelastic models. The best hyperelastic model was selected based on the smallest deviation between numerical and experimental results. Curve-fitting was done between the best hyperelastic model parameters and the compound to obtain a new correlation, and it was validated. This research shows that the neo-Hookean model with 6 % deviation is the most suitable for the SBR-BR, and the mathematical correlation for SBR-BR composition and C10 is linearly correlated. SBR60 %-BR40 % shows the optimum composition for non-pneumatic tires with the characteristic of maximum tensile strength 16.71 MPa, elongation 251 %, and 200 % modulus 13.04 MPa.

Abstract

This study presents the conclusions drawn from previous data analysis, highlighting several significant key findings. Firstly, an evaluation using a risk matrix revealed that the critical subsystem for the CC 206 Locomotive is the Diesel subsystem, which consists of four important spare part components: The respective MTTF values for the Injector Nozzle, Inverter, Seal Output, and Retainer are 29.292 hours, 18.943,1 hours, 13.442,1 hours, and 26.318,1 hours. Furthermore, the annual requirements for these components were calculated using a Poisson process based on their respective MTTF values. These findings provide valuable insights into the importance of these components and their annual requirements, which in turn will significantly contribute to the efficient maintenance and operation of the CC 206 locomotive. It is estimated that the annual requirements for these components are 21 units for the injector nozzle, 31 units for the inverter, 42 units for the seal output, and 23 units for the retainer. This study proposes a novel application of the Poisson process to estimate the annual requirement of spare parts based on actual component failure rates and their corresponding MTTF. The method offers the advantage of being data-driven, probabilistic, and suitable for systems with constant failure rates, making it highly effective for optimizing inventory levels in railway maintenance. This research provides a new insight into quantitative spare part planning that improves reliability-based inventory strategies in Indonesian railway operations.

Abstract

This article aims to give a complete review of previous and current research on numerous types of out-of-roundness (OOR) failures in train wheels, as well as diagnostic approaches based on machine learning and vibration data. The study provides a comprehensive overview of the current state of research by categorizing reviews into three primary domains: (1) types of OOR failures in train wheels, (2) fault diagnosis methodologies, and (3) the use of machine learning and vibration data to diagnose train wheel OOR failures. Initially, the study investigates the characteristics, causes, and consequences of railway wheel OOR failures, including their impact on vibrations. It then dives further into diagnostic methods, comparing the effectiveness of statistical methods to machine learning-based methods for diagnosing failures. Furthermore, the study addresses current advances in machine learning and vibration-based diagnostic methods to diagnose train wheel OOR failures, providing information on their applications and results. This article highlights that by utilizing machine learning methods with vibration data offers a promising way for accurately diagnosing OOR faults in train wheels and predicting their potential failure and remaining useful life, resulting to enhanced maintenance efficiency and less downtime.

Abstract

One of the important components on a combat vehicle is the ground pad shoe (GPS) or track pad. GPS that has been developed at this time mostly uses rubber material. Rubber raw materials themselves are found in Indonesia in large amount. Indonesia left 3 million tonnes of natural rubber unprocessed in 2018. On the other hand, natural rubber research is quite expensive and takes a long time to become a product. To make rubber products is needed special molds and tests. To solve the high costs and long time involved in rubber research, it is necessary to carry out numerical research. In this study, a numerical study of GPS rubber for combat vehicles was carried out with a hyperelastic material model. The research was conducted experimentally and numerically. Tensile testing is carried out on imported GPS samples which are then used as comparison data for numerical studies. The Mooney-Rivlin, Neo-Hookean, Yeoh, and Ogden hyperelastic models were varied to get the stress and strain values ​​closest to the experimental test. The results of the numerical study show that the best hyperelastic model for the imported GPS rubber model is the Neo-Hookean model. The tensile strength of GPS according to the experimental tensile test results is 16.93 MPa, while the result of the finite element method (FEM) is 16.75 MPa. The GPS modulus 200% according to the experimental tensile test results is 14.7 mm/mm, while the FEM result is 15.3 mm/mm. The difference between the FEM and experimental test values ​​for tensile strength and modulus 200% are below 5%. Maximum stress on GPS is 4,4 MPa and safety factor 3,8.
