Rotating machines that have been operating within a certain period of time there is frequent vibration. The vibration is usually caused by unbalance, misalignment, bearing defect, and others. Unbalance is ranked as a first cause of vibration, which more than 80% cases of vibration caused by unbalance. This condition causes the balancing process needs to be done. A commonly method of vibration measurement uses vibration sensors such as accelerometer or vibrometer, that should be affixed to the machine in operation. This can cause discomfort and may even dangerous the operator when measuring the machines. The solution of the problem can be done using non contact measurement, where the sensor is not attached directly to the test equipment. Microphone is a device that can record the sound signal without necessarily contact the tested device. The unbalance tendency of the test is characterized by the presence of the dominant frequency at one rotational speed (1 x rpm). From the test, the result of balancing of normal condition on one rotor and two rotors are 0.039 V and 0.031 V with balancing efficiency 87.88% and 80.74% respectively. The addition of unbalance mass on one rotor and two rotors is obtained balancing result of 0.031 V and 5.88x10-3 V with efficiency balancing of 93.58% and 97.43% respectively.Keywords : voice signal, unbalance, balancing, microphone, unbalance mass

Machines that operate under certain conditions will experience a performance degradation that will cause vibration, one of which is caused by unbalance symptoms. Machines with unbalance conditions that occur under safe conditions can damage components in a machine. One of them is the damage to the bearing and the entire shaft system of a machine. Efforts to overcome this matter required preventive maintenance with the contact measurement method by attaching a vibration sensor in the form of an ADXL335 accelerometer with the help of Arduino. Accelerometer ADXL335 is attached to the engine component that is operating with the sensor output measurement in the form of vibration signal amplitude. The unbalance indication of the test is characterized by the presence of the dominant frequency at one rotational speed (1xRPM). From the test, the result of balancing of normal condition in one rotor are 0.0165 G with balancing efficiency 78.47 %. The addition of unbalance mass on one rotor obtained balancing result that is 0.01593 G with efficiency of balancing respectively 78.09%.Keywords: vibration signal, unbalance, balancing, Accelerometer, Arduino, ADXL335, unbalance mass

PENGARUH RASIO MASSA KITIN/NaOH DAN WAKTU REAKSI TERHADAP KARAKTERISTIK KITOSAN YANG DISINTESIS DARI LIMBAH INDUSTRI UDANG KERING. Kitosan merupakan polimer yang dapat dibuat dari kitin menggunakan proses deasetilasi. Tujuan penelitian ini untuk mempelajari pengaruh rasio massa kitin dengan volume NaOH dan waktu reaksi terhadap karakteristik kitosan yang disintesis dari limbah industri udang kering. Kitin diisolasi dari cangkang udang dengan metode deproteinasi dan demineralisasi. Deasetilasi kitin dilakukan pada suhu 120 °C, kecepatan pengadukan 150 rpm, rasio massa kitin dengan volume NaOH 1:15, 1:20, 1:25 (w/v), dan waktu reaksi 0,5-3 jam. Hasil penelitian menunjukkan bahwa peningkatan nilai rasio massa kitin dengan volume NaOH terhadap waktu reaksi mengakibatkan peningkatan derajat deasetilasi dan penyusutan kadar abu dan rendemen kitosan, sedangkan kadar air tidak memiliki efek yang signifikan. Derajat deasetilasi kitosan adalah 85,7% pada rasio massa kitin dengan volumeNaOH 1:15 selama 3 jamdanmeningkatmenjadi 86,1%setelah rasiomassa kitin dengan volume NaOH ditingkatkan menjadi 1:25. Kadar rendemen berkisar antara 86,6 % hingga 63,5 %, kadar air kitosan berkisar antara 1,2 % hingga 1,0 %, dan kadar abu kitosan berkisar antara 1,9 % hingga 1,1 %.

Kopling T.B Woods Elastomeric merupakan kopling yang digunakan pada mesin kompresor udara jenis screw. Kebakaran pada kompresor pernah terjadi di PT Semen Padang, akibat kerusakan yang tidak terdeteksi pada kopling berbahan buttyl rubber tersebut. Studi kasus ini bertujuan untuk mengetahui penyebab kegagalan dari kopling kerusakan tersebut melalui pendekatan teoritis. Bagian kopling terdiri atas gigi-gigi pencekam, bidang utama, serta lubang kopling yang diberi hub. Bidang utama kopling berbentuk seperti silinder bertingkat dengan sambungan berupa chamfer. Tegangan maksimum terdapat pada bidang utama kopling sebesar 1,0852 MPa dengan jumlah siklus akibat fatik sebesar 5,6x107 siklus, sehingga lifetime dari kopling adalah 164,5 hari. Beban torsi dari putaran poros motor dan rotor secara terus menerus mengakibatkan terjadinya fatik, yang meyebabkan retakan pada daerah chamfer dan merambat ke seluruh bagian kopling

Chatter is an excessive vibration that occurs due to performing of tools which have a negative effect that causes poor surface quality, disproportionate use of tools, damage to equipment, and etc. By these reasons chatter has became important research area in mechanical engineering to detect its existence in operational condition of machining process. In this research, the chatter detection method by using sound signal was developed. The artificial chatters were then generated by unsharpening the lathe cutting. The uncalabrated microphone which operated by PC and MATLAB software was then used to grap the sound data from operating turning process. The sound signals in normal and chatter condition were then processed to perform sound signal in the time domain, frequency domain, and spectrogram. The existence of chatters was signed by excessive vibration and bad roughness of turning process product. The Spectogram display TF representation, Time-Magnitude domain and 3D spectrogram. TF representation showing magnitude enhancement, that occurs during the chatter. the Time-Magnitude domain showing time span of the chatter and 3D spectrogram can be seen in the contours and characteristics from chatter. From whole of representation, the chatter can be detected.Keywords : Sound Signal, Chatter, Turning Process, Spectrogram

Machining processes in manufacturing industries such as machine tools required special monitoring during the operation process. Cutting tool is a component that needs to be monitored, because it is a part that often suffered damage or wear. In this research the Monitoring is conducted to determine the damage or wear that occurs on the tool HSS lathe and drill. The method used is the indirect method, where the sound signal is recorded by using the microphone as a sensor through the software. The obtained sound signal is then processed by using fast fourier transform (FFT). The results show that there is a difference in the amplitude value of time domain signal and frequency domain. The tendency is the more wearness, the higher the amplitude of sound signal which can be seen clearly in time domain and frequency domain.Keywords : Tool Wear, Sound Signals, Machine Tools, FFT

Structural Health Monitoring (SHM) is a process of identifying damage by Nondestructive Evaluation (NDE). The method can be done by non-contact method. In this study a non-contact method was proposed to monitor the specimen by utilizing the sound signal as an excitation. This method has advantage becauseit is not costly toset-up testing.Excitation is given to specimen by the loudspeaker. The sound response on the specimen is recorded through the microphone. Recorded data in the form of time domain is transformed into a frequency domain using FFT (Fast Fourier Transform) method. The domain data frequency response and data excitation frequency can be processed into data of FRF(Frequency Response Function).FRF matrix form is used to estimate the mode shape. The first Natural frequency of mode shape is transformed to detect the location of damage. The study was performed on specimen under normal and damaged conditions. The result of the research on simulation and testing show that proposed method can detect the location of the damage properly and accurately. Keywords: Signal Sound, SHM,FFT,FRF,Mode Shape
