Indonesia is a big country which has many isolated power system networks. Sumatera power system is one of the main power system networks in Indonesia that supplies electricity for more than 45 million inhabitants in Sumatera Island. For the transmission topology and load characteristic, there are some dynamic stability problems in Sumatera power system such as voltage and small signal stability. To...
One of the important factors that support the advance of agriculture system is the quality of the soil, which is used as a medium for growing the plant. The soil quality is a fertile soil and able to give a productive harvest. There are several environmental factors which influence the soil conditions, such as temperature, soil humidity, light, pH of the soil, etc. In this paper, we are designing...
Wireless Body Area Network (WBAN) is one of developed technology that supports telemedical services. WBAN provides low power consumption, mobile, and easier monitoring. This application needs a wearable device especially a textile antenna for implementation. So far, the antenna's performance is mainly affected by a human body when it is applied near to the human body. In this paper, we propose a novel...
A system providing accurate environmental data for campus stakeholders to formulate and evaluate policies of the sustainable campus development is needed. This paper presents the design of WSN infrastructure capable of providing accurate, real-time and reliable environment data, namely PM2.5, SO2, CO, O3, NO2, temperature, humidity, soil moisture and light intensity to be analyzed and presented by...
Thalassemia is an inherited blood disorder that requires lifelong disease management and therefore poses a pecuniary challenge in public health management in Malaysia. Constant monitoring of patients throughout their life requires novel adaptation of new technologies to enhance the effectiveness and success of the complex disease treatment regimen. In this paper we present a prototype mobile health...
In diagnosis, planning, intervention and monitoring of the potentially fatal Coronary Artery Disease multimodal medical imaging plays an important role. Medical cardiac images of patients suffering from Atherosclerosis exhibit information on cardiovascular plaque that can cause a sudden death due to its vulnerability. The identification of vulnerable plaque is an important research field and can be...
Wireless Sensor Network using many wireless communication protocols, such as Bluetooth, ZigBee, ultra wideband, and wifi. Wifi has the advantages of high data rate and long range distances, but it requires a great power. While ZigBee has the advantages that it uses less power, but the resulting low data rate and short range distances. With respective these advantages and disadvantages, this paper...
Wireless Sensor Network is increasingly popular in the field of microclimate monitoring due to its promising capability. Wireless Sensor Network using many wireless communication protocols, such as Bluetooth, ZigBee, ultra wideband, and WiFi. WiFi has many advantages, i.e high data rate and long range distances, but it requires a high power. ZigBee uses less power, but it offers low data rate and...
Radio Frequency Identification (RFID) is one of the developed technologies, which is used in several applications, including for medical field applications. For patient monitoring purpose, the RFID system is consisted of a medical tag that is implanted into the human body and a reader unit that is installed away from the human either in proximity or far away from the human body. By this communication...
In this paper, the development of a cost-effective shooting simulator is presented. The proposed system employs the photodiode sensors for detecting the laser pointer. To reduce the cost, the photodiode sensors are arranged into rows and columns, and the scanning technique is adopted to detect the presence of the laser beam on the sensor arrays. A cheap microcontroller system AT89S52 is used to perform...
