Along with the increasing of infrastructure development in Indonesia especially in jepara, so the necessary of material also increase, for example: sand. Nowadays, muntilan is the sand that often be used in making infrastructure in the government because it is considered that it has the good quality, whereas in the other hand the river sand is also abundant, but the government perverted mintilan sand as the development material. River sand is usually used by the middle to lower county because the house because the price is cheaper than muntilan sand. After doing this research we hope that: can know the quality of the river sand if it is used in infeastructure, knowing the river sand in jepara that have the good quality, such as: keling sand, bangsri sand, The stages of this research are: preparation, sand inspection (mud content and organic faces, filter analysis, moister content and weight, and specific gravity), making spacimens based on SKSNI 03-6825-2002 ASTM C 305, making compressive strength test. The test result show that at 3,7,14,21,28 days old show that keling sand (93,2 kg/cm2), bangsri sand (135,2 kg/cm2). The use of river sand as the construction material by the government and community will have consequence on the balance kf muntilan sand and river sand. The specific treatment on the river sand will that quality that is almost same as muntilan sand. © Published under licence by IOP Publishing Ltd.

Indonesia is one among countries that produce abundant of rice straw every year generated as post-harvesting residue from paddy field all over country. This abundant amount residue is highly potential to be utilized as carbon source in producing single cell protein (SCP) in solid state fermentation system. SCP is a microbial protein that can be used as alternative protein for substitution of available conventional protein sources such as;fish meal, soy bean, and corn Stover for animal feed production. This research was conducted to evaluating the effects of initial medium pH of substrate (mixed rice straw pulp-urea), fermentation time and fermentation temperature on SCP production by Trichoderma reesei in solid state fermentation (SSF). The results showed that the highest SCP yield (19.71%) was produced at the initial medium pH of 5 and temperature of 30 °C at SSF conditions of C/N ratio 20:1 for 12 days of fermentation time. © Published under licence by IOP Publishing Ltd.

Ultraviolet (UV) irradiation in biomaterial synthesis is commonly used to do sterilization and to improve the physical characteristics. This study is aimed to study the characteristics of polyvinyl alcohol-Aloe vera (PVA-AV) nanofibers from electrospinning process, that was exposed by UV for 6 h with various power of 8, 10, 15, and 20 W. The physical properties of the fiber were characterized by using Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR), Differential Scanning Calorimetry (DSC) test, and water absorption test. The SEM images showed that the nanofibers were formed with s homogeneous structure and no bead was observed. The diameter and the thickness of the nanofibers are increased with the increase of the power of UV exposed to the samples. The biggest diameter was 319.60 ± 56.17 nm obtained at UV exposure power of 20 W. The FTIR test result indicated that there was no new chemical bond after the PVA-AV was exposed by UV. Meanwhile, the DSC test showed that the increase of power could increase the melting temperature (Tm) with the highest value of 189.51°C at UV exposure power of 20 W. The water absorption test showed that the highest water absorption was 739.6 % obtained at UV exposure power of 20 W. © 2020 Trans Tech Publications Ltd, Switzerland.

Indonesia meets the needs of 50% of the world's palm oil needs. Sources of Indonesian palm oil, 34 % are produced by independent smallholders. The lack of governance of independent smallholders leads to low productivity of their crops. Global market demands for palm oil derivative sources become an obligation to compete. The development of blockchain technology that favors traceability and transparency is applied in the supply agriculture sector, and this is an opportunity for how blockchain technology can help the palm oil supply chain become transparent and can find its source. This research uses the system development life cycle (SDLC) method. And business process model and notation in business model design. The results of the design of the FFB sale and purchase transaction system with blockchain technology have succeeded in connecting farmer transactions as FFB providers with traders and PKS as FFB buyers. Every transaction sent by the farmer will be locked by a hash, as immunity makes the data sent immutable. The system can display the traceability of transactions while maintaining the integrity of member information.

This study investigates the grain size characteristics and sediment types of the Aceh's coastal deposits that are primarily based on the sieve analysis. This study is mainly driven by two reasons. Firstly, this study is a preliminary effort to identify coastal sediment in the Aceh coastal areas. Secondly, this information is important to interpret the support mechanism of sediment during transportation and depositional processes. In this study, many sediment deposits from both the east and west coasts of Aceh were collected. Laboratory sieve analysis was carried out to these samples. Then, further analysis of this sieve analysis results is carried out. The analysis reveals the past transport mechanism of this study sand deposits which is river's channel. However, such finding should be investigated further as all the tested sand were taken at the top surface and big main rivers are not indicated at both sand locations. © Published under licence by IOP Publishing Ltd.

Elbow angle estimation for medical rehabilitation device based on EMG sensor with ARIMAX method

引用

AIP Conference Proceedings 2022年第1期2663卷

作者： Amelia Lita I. Made Mas Dwiyana Prasetya Wibawa Alinda Anggraini Akif Rahmatillah Riries Rulaningtyas Alfian Pramudita Putra Khusnul Ain 1Biomedical Engineering Study Program Department of Physics Faculty of Science and Technology Universitas Airlangga Surabaya 60115 Indonesia

In the development of medical rehabilitation tools, muscle signals or electromyographic (EMG) are often used as feedback from the body in order to facilitate normal movement patterns. Through this signal, the force, torque, and angle can be estimated to produce the desired movement in the robot to assist patients in rehabilitation therapy. There had been various research done on estimating the extremities' joint angle, including the system identification method with Auto-Regressive Integrated Moving Average with Exogenous Input (ARIMAX) model structure. This research aims to model biceps brachii's EMG signal and the elbow joint angle using the ARIMAX model structure. In modeling, the order of the model was selected using the methods of minimizing the AIC (Akaike Information Criteria) and RMSE (Root Mean Square Error) values. The reported results showed the comparison of the outcome and model orders from three data sets with a frequency sampling of 47.6690 Hz, l66.3248 Hz, and 935.6743 Hz, respectively. The frequency sampling of l66.3248 Hz results showed the best accuracy performance of the ARIMAX model structure. The model order which is selected based on the minimization of the RMSE value obtained the best estimate, while the order models were selected based on the minimization of the AIC value showed a more consistent performance on the data estimation and validation.
