<![CDATA[There is currently no standard for the Specific Energy Consumption (SEC) in the palm oil industry. SEC is a value that can be used as an indicator to measure the optimization level in the use of energy. Indonesia as one of the largest palm oil producing countries requires a standard for energy intensity in the palm oil industry. SEC in palm oil mill is defined in the amount of energy per unit of production (kWh/kg). The classifying method that has been used in this study is K-means cluster analysis with the measurement samples in 14 palm oil mills for 12 months of period. This study has suggested the SEC standard for Indonesian palm oil industry and it is expected to be SEC reference for other studies in the palm oil industry.]]>

<![CDATA[The gesture is one of the most natural and expressive methods for the hearing impaired. Most researchers, however, focus on either static gestures, postures or a small group of dynamic gestures due to the complexity of dynamic gestures. We propose the Kinect Translation Tool to recognize the user's gesture. As a result, the Kinect Translation Tool can be used for bilateral communication with the deaf community. Since real-time detection of a large number of dynamic gestures is taken into account, some efficient algorithms and models are required. The dynamic time warping algorithm is used here to detect and translate the gesture. Kinect Sign Language should translate sign language into written and spoken words. Conversely, people can reply directly with their spoken word, which is converted into literal text together with the animated 3D sign language gestures. The user study, which included several prototypes of the user interface, was carried out with the observation of ten participants who had to gesture and spell the phrases in American Sign Language (ASL). The speech recognition tests for simple phrases have therefore shown good results. The system also recognized the participant's gesture very well during the test. The study suggested that a natural user interface with Microsoft Kinect could be interpreted as a sign language translator for the hearing impaired.]]>

<![CDATA[Final Gear terdiri dari pinion gear dan ring gear, yang terletak di dalam differential atau gardan. Terdapat hubungan antara final gear pada pinion gear dengan efisiensi daya / power engine kendaraan atau truck. Daya/Power Engine pada truck dinyatakan dalam satuan hp dimana Power yang dibutuhkan kendaraan di pengaruhi oleh daya tahanan gelinding, daya tahanan udara, daya tahanan kelandaian, daya energi kinetis dan daya internal engine. Awal penelitian dimulai dengan pemilihan jenis pinion gear baik dari sisi harga, material, jumlah gigi, suku cadang dan kesesuaian dengan pasangannya. Dari hasil pemilihan tersebut ada 2 jenis dari 3 jenis pinion gear yang ada di pasaran dan 2 jenis tersebut menjadi sample penelitian. Yaitu jenis pinion gear dengan jumlah gigi 11 dan jumlah gigi 12. Sedangkan pasangannya yaitu ring gear dengan jumlah gigi 37. Dalam penelitian efisiensi power engine truck kapasitas 30 ton ini dikondisikan dengan 3 variasi grade jalan ( 4%, 6% dan 8%) dalam 3 kali pengujian. Dari hasil pengujian tersebut diperoleh hasil bahwa gigi pinion dengan jumlah 11 memiliki efisiensi power engine 68,5 %, sedangkan untuk gigi pinion jumlah 12 memiliki efisiensi power engine 65,1 %. Jadi kesimpulannya gigi pinion dengan jumlah 11 lebih efisien 3,4 % dibanding dengan gigi pinion dengan jumlah 12. Sehingga gigi pinion jumlah 11 mampu menghemat tenaga engine dan menghemat konsumsi bahan bakar engine.]]>

<![CDATA[A classifier plays a crucial role in the cement industry. It is in charge of separating coal that has been smoothened out and is ready to be burned although the coal is still rough after going through the grinding process. It takes a long time to burn coal that is not perfectly processed with a classifier. Therefore, it will reduce the amount of cement production, and the factories will release more energy. The closed arrangement and the number of components in the unit classifier requires a sophisticated method to detect damage that occurs early. Vibration analysis is a method that has been effectively employed in detecting the initial damage that occurs to the engine, especially the classifier. This study was aimed at detecting the location of the damage occurring in the classifier by using a vibration signal analysis and by measuring the magnitude of vibration and presenting it to the frequency domain (spectrum) form using Fast Fourier Transform. Engine condition assessment referred to ISO 10816-3 standard in velocity and displacement modes. Based on data spectrum analysis, the dominant damage laid in the unbalanced rotor. Spectrum characteristics of the damage appeared to be in the spectrum line worth 438.01 μm at a 3.5-Hz frequency (1X) radially. This analysis proved to be supported by the decrease in vibration value to 18.65 μm after balancing the Classifier rotor.]]>

<![CDATA[Nickel Oxide (NiO) have widely applied in industrial and automotive to forming oxide layer on the substrate due to it have high thermal stability and corrosion resistant. However, NiO was not directly diffused to the substrate via co-precipitation, spray-pyrolysis and sol-gel methods. Therefore, NiO-electroplating was performed in coating FeCrAl substrate by γ-Al2O3 powder. This method was conducted using various time of 15, 30, 45, 60 and 75 minutes, a current of DC power supply is 1.28A and sulphamate type solution. From the data shows that smallest surface roughness (Ra) of NiO-electroplating (EL) samples located at EL 30 min sample for 0.69 µm. Ra of raw material was lower than coated samples due to it performed by coating activity on the substrate. It supported by coating thickness analysis that treated samples has a higher coating thickness up to 11.3 µm. EDS analysis observed some elements on coated and uncoated samples such as Carbon (C) of 4.62-20.67%, Oxygen (O) of 6.16-19.62%, Nickel (Ni) of 6.76-25.14%, Iron (Fe) of 23.96-48.53%, Sodium (Na) of 2.21-9.95%, Chromium (Cr) of 7.97-15.59% and Aluminum (Al) of 2.17-3.12%. Those elements promote to develop a protective oxide layer on FeCrAl at a high temperature of 1000 0C.]]>
