    As implementation of Tri Dharma is a Community Services. This activity is carried out directly in the field by involving the public and university lecturers together in an effort to overcome the practical application of science in a comprehensive community issues. This community service focused on the in-depth problems of Islamic studies at the Serikat Amal Baik mosque in Kelurahan Sei Kera Hilir I, precisely on Jalan Ibrahim Umar Gg. Nikmat No. 7, Medan city. Working together with the partner Badan Kemakmuran Masjid (BKM) and teachers at SDIT Zahira school, conduct “Rumah Islami” studies and perform continued of comfort supporting infrastructure improvement activities as part of the worship of Islam by Zahira SDIT teachers joining together the surrounding communities. This community service activities that have been carried out concluded that the targets and outcomes achieved by seeing the enthusiasm of the participants in the Islamic spiritual education development framework on an ongoing basis

    In order to regulate the significant variations in the dynamic characteristics of a distributed collector field in a solar power plant, various control techniques including feedforward control, gain scheduling and fuzzy control have been considered in the past. This paper develops some of these previous approaches by considering the operating conditions of the plant and the desired controlled responses. The result is a control scheme that employs a fuzzy PI controller, with feedforward, for the highly nonlinear part of the operating regime and gain scheduled control over the more linear part of the operating envelope. In order to satisfy performance characteristics for the plant at different points in the operating regime, a multiobjective genetic algorithm is used to design the parameters of the fuzzy controller. To reduce the size of the search space and the resulting fuzzy controller, a hierarchical encoding is employed with the multiobjective genetic algorithm. The resulting controller is shown to both satisfy the desired performance criteria and have a reduced number of terms compared with a conventional design approac

    Batak Karo's Architecture is one of the Indonesian archipelago's architecture which is the result from the local wisdom of the Batak Karo tribe, one of the karonese architectures is the traditional Karo house. Masri Singarimbun explained that karo traditional houses are not only related to their functions but related to the process of establishment and how to dwell in it, there are so many customary rules when establishing and occupying the house. Now the Karo Batak tribe has turned to contemporary architecture and has lost its meaning in its architecture. This study will examine space in karo architecture with space theory that proposed by Christian Noberg Schultz, namely architectural space and existential space. The methodology used in this research is descriptive qualitative. It was found that karo architecture is a manifestation of the world view Batak Karo tribe which considers the world divided into three parts, namely the upper world, the middle world and the underworld and also the concretization of their kinship relationship, beru, senina and kalimbubu, which is called sangkep ngeluh

    A Preliminary Study on Attitude Measurement Systems Based on Low Cost Sensors

    The increasingly use of Autonomous Underwater Vehicles (AUVs) in several context led to a rapid development and enhancement of their technologies, allowing the automatization of many tasks. One of the most challenging tasks of AUVs still remains their robust positioning and navigation, since classical global positioning techniques are generally not available for their operations. Inertial Navigation System (INS) methods provide the vehicle current position and orientation integrating data acquired by the internal accelerometer and gyroscope. This system has the advantage of not needing to either send or receive signals from other systems; however, among the errors the sensors are mainly affected by, the most critical one is related to their drift, which makes the position error growing over time. The attenuation of the effect of these problematics is generally achieved combining different positioning methods, as for example acoustic- or geophysical-based ones. An accurate estimation of the device orientation is anyway necessary to get satisfying results in terms of position and autonomous navigation. In this paper, a preliminary study on the use of smartphone low-cost sensors to perform attitude estimation is presented. With the final aim of developing a cheaper and more accessible underwater positioning system, a first analysis is conducted to verify the accuracy of the attitude angles obtained by the integration of smartphone data acquired in different operative settings. Different filtering methods will be employed
