Abstract

In recent years, people have difficulty to breathe a good air quality. It is caused by vehicle emission, household combustion devices, forest fires, and industrial facilities are regular sources of air pollutants. These air pollutants can impair people health and behavior. It means that decreasing oxygen supply can reduce our immune system. The effect of reducing oxygen in our blood cause rapid fatigue, difficulty breathing, muscle pain, eye irritation and even more severe would have a heart attack. Monitoring peoples' health is one of solutions to increase the quality of human life. The pulse oximetry widely used to measure the oxygen level or oxygen saturation (SpO2) in the blood. While it has long been an important tool in clinical practice, pulse oximetry has become a popular medical tool for outside hospital environment use. Pulse oximetery work by the principles of spectrophotometry: the relative absorption of red (absorbed by deoxygenated blood) and infrared (absorbed by oxygenated blood) light of the systolic component of the absorption waveform correlates to arterial blood oxygen saturations. Patients usually take measure using pulse oxymetry in a stationary condition. While pulse oximetry recording a patient's oxygen level, the finger should not move until the recording is completed. The previous research have been evaluated a pulse oximetry in mobile condition. This paper will investigate the relationship between oxygen saturation and light attenuation in the proposed design of the ubiquitous pulse oximetry in mobile condition. This design will help the future development of SpO2 recording ability while patient in walking condition and give good accuracy as same as off-the-shelf pulse oxymetry.

Abstract

The production of the palm oil accounted for 10.15%of total palm oil production in Indonesia. Farmland monitoringsystem is designed to determine the condition of temperature andsoil moisture on oil palm plantation. In this study, we design andbuild a Wireless Sensor Network (WSN) with fitted temperatureand moisture sensors for monitoring soil quality. The process oftemperature and moisture data communication from sensor nodesto the sink using a routing protocol that named Power-EfficientGathering in Sensor Information Systems (PEGASIS). The routingprocess in the PEGASIS is the nodes will form a chain by selectinga leader node as a gateway. The development of WSN is composedof 3 nodes and 1 sink with three different scenarios. The firstscenario is placed moisture sensors on three nodes (single sensor),the second is placed the temperature sensors on three nodes (singlesensor) and the third is placed moisture sensor on two node and onenode equiped by temperature sensor (multi sensor). The evaluationof WSN communication using the PEGASIS routing protocolcompared to the direct transmission using delay, packet loss andenergy have done. The results obtained are the difference betweenthe lifetime sensor nodes between direct transmission and thepegasis is 7 minutes time difference. For the average delay ofPEGASIS and direct transmission is 31.23 and 30.92 msrespectively. All transmission in both scheme have packet loss 0%.Conclusion, the WSN has successfully implemented with longer lifetime energy using PEGASIS than direct transmission methods.

Abstract

The information framework aims to holistically address the problems and issues posed by unwanted peat and land fires within the context of the natural environment and socio-economic systems. Informed decisions on planning and allocation of resources can only be made by understanding the landscape. Therefore, information on fire history and air quality impacts must be collected for future analysis. This paper proposes strategic framework based on technology approach with data fusion strategy to produce the data analysis about peat land fires and air quality management in in South Sumatera. The research framework should use the knowledge, experience and data from the previous fire seasons to review, improve and refine the strategies and monitor their effectiveness for the next fire season. Communicating effectively with communities and the public and private sectors in remote and rural landscapes is important, by using smartphones and mobile applications. Tools such as one-stop information based on web applications, to obtain information such as early warning to send and receive fire alerts, could be developed and promoted so that all stakeholders can share important information with each other.
