Solar Photovoltaic (SPV) generation system is one of the renewable energy sources that is currently experiencing increased penetration on the grid. Generally, SPV panels are installed at a certain tilted angle. This type of installation has its own drawback such as when the sun’s position is behind the SPV panel, the energy produced decreases. To overcome this condition, the SPV panel with the dual axis sun tracker system is designed and implemented. The designed dual axis sun tracker of this research has several main components, such as 4 LDR sensors for detecting the position of the sun and the Arduino microcontroller used to read the measurement from the LDR sensors, processing these measurement data and instructing the actuator to drive the SPV panels at a perpendicular incident angle. The actuator is made from 2 servo motors for each vertical and horizontal axis respectively. It can be seen from the results that the use of dual axis sun tracker is capable to increase the “energy gain” up to 60 %. It is also worth noting that the use of this dual axis sun tracker has a big potential to apply in the tropical region such as Pekanbaru City, Indonesia.
太阳能光伏(SPV)发电系统是目前在电网中日益普及的可再生能源之一。SPV板一般以一定的倾斜角度安装。这种类型的安装有它自己的缺点,如当太阳的位置在SPV面板后面,产生的能量减少。为了克服这种情况,设计并实现了带有双轴太阳跟踪系统的SPV面板。本课题设计的双轴太阳跟踪器主要由几个部分组成,其中4个LDR传感器用于检测太阳的位置,Arduino微控制器用于读取LDR传感器的测量数据,处理这些测量数据并指示执行器以垂直入射角驱动SPV面板。执行器由2个伺服电机组成,分别用于垂直轴和水平轴。从结果可以看出,使用双轴太阳跟踪器可以将“能量增益”提高60%。同样值得注意的是,这种双轴太阳跟踪器的使用在印度尼西亚北干巴鲁市等热带地区具有很大的应用潜力。

The development of research related to the use of domain ontology in requirement elicitation in recent years has enabled improvement on process effectiveness and efficiency. The implementation of domain ontology has enhanced requirement elicitation process in many ways, among others: in defining requirements specification and constructing test cases. However, building a domain ontology requires great effort by considering the quantity and type of input data. Our study proposes a methodology in building domain ontology by utilizing Business Process Modeling Notation (BPMN), a popular semi-formal modeling language. Ontology classes are built by finding potential term from BPMN components and defining semantic relation among the components. This study produces two outputs: the proposed methodology in domain ontology development with BPMN as data input and the domain ontology as the implementation of the proposed methodology implementation in university’s academic process as a case study.
近年来,领域本体在需求提取中的应用研究的发展,提高了需求提取过程的有效性和效率。领域本体的实现在许多方面增强了需求激发过程,其中包括:定义需求规范和构建测试用例。然而,构建领域本体需要考虑输入数据的数量和类型,需要付出很大的努力。本文提出了一种利用业务流程建模符号(BPMN)构建领域本体的方法,BPMN是一种流行的半形式化建模语言。本体类是通过从BPMN组件中寻找潜在项并定义组件之间的语义关系来构建的。本研究产生了两种结果:以BPMN为数据输入的领域本体开发方法和以领域本体为案例研究的方法在大学学术过程中的实施。

To date, sulphur hexafluoride (SF6) gas has been the predominant insulation medium in high voltage applications which mainly due to its exceptional physical and electrical properties. However, environmental concerns arise since SF6 is a potent greenhouse gas. In this study, the breakdown behavior of SF6/N2 gas mixtures under non-uniform field is investigated. A breakdown voltage test on SF6/N2 gas mixtures which subjected to AC voltage was conducted inside a pressure vessel. The gas mixture ratio was fixed to 10/90, while the total gas pressure was varied between 0.11 MPa to 0.15 MPa with 0.01 MPa intervals. Meanwhile, R6-Plane electrode configuration was used to produce a non-uniform field where the electrodes gap distance was varied between 5 mm to 30 mm. The results show that the breakdown voltage of SF6/N2 (10/90) gas mixtures increases linearly with the increase of gas pressure and electrodes gap distance. However, it is found that the effect of electrode gaps distance is more dominant to cause the breakdown voltage of SF6/N2 gas mixtures to increase, as compared to the effect of small range of pressure levels.
迄今为止,六氟化硫(SF6)气体一直是高压应用中主要的绝缘介质,这主要是由于其特殊的物理和电气特性。然而,由于SF6是一种强效温室气体,环境问题也随之出现。本文研究了SF6/N2混合气体在非均匀场作用下的击穿行为。在压力容器内对SF6/N2混合气体进行了交流电压击穿电压试验。气体混合比固定为10/90,总气压在0.11 ~ 0.15 MPa之间变化,间隔为0.01 MPa。同时,采用r6 -平面电极结构产生非均匀场,电极间隙距离在5 ~ 30 mm之间变化。结果表明:SF6/N2(10/90)混合气体的击穿电压随气体压力和电极间隙距离的增加呈线性增加;然而,与小范围压力水平的影响相比,电极间隙距离对SF6/N2混合气体击穿电压升高的影响更为主导。

The electrical energy produced by photovoltaic (PV) is very dependent on weather conditions and the amount of solar irradiation received. Maximum power point tracking (MPPT) Fuzzy logic controller is used to increase the power generated by PV. In this study, comparing the performance of fuzzy logic controllers with two types of algorithms, namely, Perturb and Observe (P&O) and Incremental Conductance (InC). The research was carried out with simulations using Simulink Matlab and fuzzy logic control. The Buck-boost converter is used to control the power flow from the PV panel to the load. Maximum power is obtained by setting the value of the duty ratio of the buck-boost converter. Based on the simulation results of the two algorithms, the Incremental Conductance algorithm is able to track the maximum power of the module better and faster. With the maximum power of the module of 50.3 W and the output power that can be channeled at 47.25 W. The Perturb and Observe algorithm is able to reach the maximum power of the module of 50.18 W and the output power of 47.13 W.

Fixed WiMAX network access requires Customer Premise Equipment (CPE) that uses small and easy to integrate antennas. This research will design a 4 element microstrip antenna using an H-shaped patch with the addition of a circular slot in the center. Antennas are used for fixed WiMAX CPE applications at 3.5 GHz (3.4–3.6 GHz) working frequency. The substrate used is FR4 with dielectrics constant 4.4 and Duroid with dielectrics constant 2.2. The feeding technique used is microstrip line. Determination of antenna dimension is done by using mathematical equation. Result design using software simulation obtained VSWR antenna using FR4 was 1.013, return loss −43.803 dB and gain 4.7083. While VSWR antenna using Duroid substrate was 1.015, return loss −42.5923 dB, and gain was 8,486 dB. Characterization of rectangular and circular slot sizes affects the working frequency range. Antenna with FR4 substrate has optimal working frequency on rectangular stripe characterization of 4 mm, 4.5 mm, and 5 mm width with 2–3 mm slot size variation. Duroid substrate design antennas have optimal working frequency with rectangular piece characterization of 5 mm, 5.5 mm, and 6 mm and variations of 4 – 5 mm slot size.

Landslide is one of the most frequent disaster happened in Indonesia. It can occur due to some major factors, e.g.; high rainfall and soil moisture. In order to predict the occurrence of landslide disaster, data sensing system of these factors are acquired. A prototype of data acquisition is proposed. The prototype provides sensors for sensing of four parameters, which are MPU 6050 sensor, tipping bucket with reed switch, two of FC-28 humidity sensors, and 801s sensor, to measure slope, rainfall, moisture, and ground vibration, respectively. This system is also equipped with the process of data retrieval or log data in real-time with SD Card in the process directly and delivery via the server via SIM900. From the sensor test results, which are obtained from reading value of each sensor, the system shows low error values of 0.165, 0, 0, 0.39, and 0.71, for MPU6050, tipping bucket, 801S, and the two of FC-28 sensors, respectively.
山体滑坡是印尼最常见的灾害之一。它可能是由一些主要因素引起的,例如;高降雨量和土壤湿度。为了预测滑坡灾害的发生,建立了这些因素的数据传感系统。提出了一种数据采集样机。样机提供了四个参数的传感器,分别是MPU 6050传感器、带簧片开关的倾卸斗、FC-28湿度传感器两个和801s传感器,用于测量坡度、降雨量、湿度和地面振动。本系统还配备了过程中直接用SD卡进行数据检索或实时记录数据,并通过SIM900通过服务器传送。从各传感器的读数测试结果来看,系统对MPU6050、铲斗、801S和FC-28两个传感器的误差值较低,分别为0.165、0、0、0.39和0.71。

Wireless Sensor Network (WSN) has gained enormous popularity since it is a base of an Internet of Things and applied in many areas of application. However, this network suffers an energy constraint issue which has to be tackled. Medium Access Control (MAC) manages the radio communication of transmitter and receiver, which is the highest energy consumed of sensor nodes. Therefore, many researchers have been proposed new MAC protocols to overcome this limitation. This paper explores and compares several MAC protocols for clustering WSN. Clustering network has a different characteristic since it classifies nodes as Cluster Heads and Cluster Members. This leads to a unique approach in developing MAC to enhance the network’s performance.
无线传感器网络(WSN)作为物联网的基础,在许多领域得到了广泛的应用。然而,该网络面临一个必须解决的能源限制问题。MAC (Medium Access Control,介质访问控制)是传感器节点中能量消耗最高的一种,用于管理发送端和接收端之间的无线电通信。因此,许多研究人员提出了新的MAC协议来克服这一限制。本文探讨并比较了用于聚类WSN的几种MAC协议。集群网络有一个不同的特点,因为它将节点分为簇头和簇成员。这导致了开发MAC以提高网络性能的独特方法。
