<![CDATA[Healthcare expenses can be significantly reduced, and lives saved by enabling the continuous monitoring of patient health remotely using Wireless Body Sensor Networks (WBSN). However, an energy efficient mobile gateway (e.g. 5G smartphone) is required which moves with the patient in real time to process the data from the bio sensors without depleting the battery. Thispaper proposes a 5G based healthcare cardiovascular disease Remote Monitoring system called 5GREM using Electrocardiogram (ECG) bio sensor as a BSN device. The aim is to monitor and analyse the patient’s heart rhythms and send emergency alerts during irregularities to the nearest caregivers, ambulance or physician to minimize heart attacks and heart failures while saving energy. Since ECG signal execution is computer intensive, requests from the ECG sensor are either executed locally on thegateway, offloaded to nearby mobile devices or to the 5G edge while considering the battery level, CPU level, transmission power, delays and task fail rate.]]>

<![CDATA[The introduction of Electronic Health Records (EHR) has opened possibilities for solving interoperability issues within the healthcare sector. However, even with the introduction of EHRs, healthcare systems like hospitals and pharmacies remain isolated with no sharing of EHRs due to semantic interoperability issues. This paper extends our previous work in which we proposed a framework that dealt with semantic interoperability and security of EHR. The extension is the proposal of a cloud-based similarity analyzer for data structuring, data mapping, data modeling and conflict removal using Word2vec Artificial Intelligence (AI) technique. Different types of conflicts are removed from data in order to model data into common data types which can be interpreted by different stakeholders]]>

<![CDATA[Interior designer is a profession that is most responsible for the whole series of human activities on this earth. It is very important to place this concept because all important aspects of the human life in this space are fully in contact with the profession of interior designer. The education of interior designing is not just about creating ideas on how to create beauty and designspaces, but also about having responsibilities on various aspects in life. In the era of digitalization and where the components of life become increasingly complex, interior designers must be able to play the appropriate role to solve life’s problems. The developments in various aspects of ecology are also connected to interior designers, for example, recycling the waste must be one of interior designer’s goals. Experimenting, innovating, and becoming part of social life is the actual responsibility of interior designer, not living in the works of hedonism. This paper aims to highlight the concept work of MESE (material-experiment and social-entrepreneurship) in the interior design.]]>

<![CDATA[Magnesium (Mg) and its alloys seem to be a potential biodegradable bone scaffold materials as their biocompatibility and mechanical properties fit to natural bone. Magnesium alloys as biomaterials have higher mechanical properties that may close to cancellous bone once composed and produced in a specific production route. Fabricating porous magnesium for bone scaffold material aims to reduce the rigidity and strength of the material by which the porous density can be adjusted to the original nature of the bone. It forms interconnected porosity, has physical and mechanical properties similar to cancellous bone. This paper describes the production and characterization of porous magnesium material for the potential application as bone scaffold through powder metallurgy technique with pieces of Titanium Wire Space Holder. Mg containing titanium pieces were then compacted and sintered before immersed in hydro fluoride acid solution to form a porous magnesium structure. Density and porosity, micro Vickers hardness, micro structure test and SEM-EDX were performed to prove the existing porous structure inside Mg metal. The result finds out that a good cooperation and a potential application for the fabrication of an inter-connected porous magnesium samples for cancellous bone implant.]]>

<![CDATA[In beef route delivery, many logistics companies have problems in making delivery plans correctly. Most logistics companies have a limited number of trucks, but there are shipping schedules, locations and volumes of demand is not fixed, in addition to returning products with various reasons that must be collected. Therefore the purpose of this study is to assign trucks to fulfill all beef delivery activities at a minimum cost. One reason for research on truck assignments in beef delivery is the high cost of shipping because it uses cold chains. This study uses the DBSCAN method to obtain density values based on customer distance to the central warehouse and the number of delivery requests, the data used in this study is the data of product delivery to customers for 6 months. Clustering research results using DBSCAN show the maximum values for epsilon 0.7 and Minpoints 2 are 3 clusters with 6 noises. with these results divided of trucks based on clusters is 2 trucks for the area of Banten, 7 trucks forthe area of Jakarta, Bogor, and Bekasi, 2 trucks for Malang, and Surabaya, and 1 truck for the Bali area and noise or non-permanent delivery.]]>

<![CDATA[One of river flow components considered in watershed management is baseflow, the main contributor to the river flow during dry season. Ratio between baseflow to total flow is called Base Flow Index (BFI). In fact, BFI can be used as an indicator how good the catchment hydrology is. The purpose of this study is to analyze BFI of Way Seputih river at Buyut Udik Hydrometry Station. The method includes Recursive Digital Filter (RDF) method, which utilizes constant recession of hydrographs in displaying the ratio of baseflow from continuous discharge during periods when there is no direct runoff. Daily discharge data from Way Seputih river at Buyut Udik recorded from 1973 to 2006 is used. The result shows that yearly BFI values range from 0.142 to 0.487 and there is a decrease trend of yearly BFI over time. This result is confirmed by yearly average discharges which tend to decrease over time. These are affected by land cover degradation in Way Seputih catchment and this should be a concern for authorities to improve land and water conservation in Way Seputih catchment so that river flow could be maintained throughout the year]]>

<![CDATA[Arjowilangun Village is one of the most significant areas of origination in the Malang Regency for Indonesian migrant workers aiming to work overseas. The remittance sent by Indonesian migrant workers can be utilised to support the Designative program, by establishing and developing entrepreneurship. The growth and development of entrepreneurship can be formed from theparticipation of the village community. Community participation in developing independent entrepreneurship can in turn boost village development. In line with Indonesian culture, rural communities still put forward kinship, trust, mutual cooperation, networking and high social norms (social capital component). This research aims to identify the social capital of retiredIndonesian migrant workers and their decision to start business entrepreneurship. The results of the Social Network Analysis (SNA) as identified through three approaches: rate of participation, density and centrality showed that 14 respondents had the potential to be key figures in spreading information to increase community participation in village development. While the results of the correlation analysis indicate that the decision to start a business were influenced by the high value of their social capital, higher social capital can encourage the community to become entrepreneurs, enabling them to have a positive influence on village development.]]>

<![CDATA[This paper seeks to utilize the improved model of reverse charging scheme. Reverse charging basically is defined as a capability of stored network that replaces the network used when the network is suddenly shut down. In this paper, charging back on 3G and 4G network that is user automated platform, will change the access of 4G to 3G and on the contrary when platform conduct thehosting. This research was solved as a problem Mixed Integer Nonlinear Programming (MINLP) by LINGO 13.0. An optimal pricing scheme is applied to a local data server, including digilib traffic and mail traffic. The improved model of Reverse Charging is modified into 4 cases and formed by setting the base price (?) and service level (?). Based on the analysis that has been done, the results of this study indicate that the reverse charging model can be utilized Internet Service Provider (ISP) to maximize profits and provide quality services for the user if compared to previous model without reverse charging scheme]]>

<![CDATA[The design of fractal Hilbert sensor is presented in this paper. The sensor is intended to detect partial discharge (PD) in transformer insulation. The fractal Hilbert sensor designed using 4 order fractal and etching on single layer PCB board. The Hilbert fractal type is chosen as this type of sensor can be built on smaller area compare to other types. The sensor overall dimension is limited to 5x5 cm as it is proposed to be use to detect the PD presence in transformer. The sensor sensitivity is tested using a closed type TEM cell. After the sensitivity of the sensor is tested the sensor then applied to detect the PD signals emitted by void PD defect model. The results show the sensor has sensitivity as high as 10 dB. The sensor also has capability to detect the PD signals generated by the PD defect source. The waveforms captured by the sensor show the sensors can capture high frequency pulse generated by the PD source]]>
