    Proses pada bioreaktor dapat dilakukan secara aerob yaitu menggunakan bantuan oksigen dan anaerob yaitu tidak menggunakan bantuan oksigen. Pada penelitian ini dilakukan fermentasi enceng gondok untuk menghasilkan biogas menggunakan bioreaktor anaerob tipe semi-batch. Enceng gondok memiliki rasio C/N sebesar 22.5 – 35.84% yang merupakan komposisi optimum untuk ekstraksi biogas. Kinerja dari bioreaktor dalam produksi biogas dipengaruhi oleh beberapa parameter seperti pH dan temperatur. Pada penelitian ini dilakukan perancangan sistem pengukuran besaran pH dan temperatur secara online sehingga memudahkan dalam pengambilan data. Bahan yang digunakan pada proses fermentasi adalah campuran enceng gondok yang telah dicincang dan dicampur air dengan dua komposisi penambahan berbeda untuk dibandingkan. Pada Bioreaktor1 digunakan komposisi enceng gondok dan air sebesar 1:3 dan pada bioreaktor 2 digunakan komposisi enceng gondok dan air sebesar 0,75: 1,25. Hasil penelitian menyebutkan bahwa bioreaktor 2 dengan komposisi enceng gondok dan air sebesar 0,75: 1,25 menghasilkan biogas lebih aktif dibandingkan dengan bioreaktor 1 dengan komposisi enceng gondok dan air sebesar 1 : 3. Hal tersebut diketahui dari hasil pengukuran selama 76 hari. Dari hasil pengukuran juga diketahui bahwa penurunan nilai COD pada bioreaktor 2 lebih besar dari pada bioreaktor 1

    Magnetic Interactions of Neighbouring Stator Sets in Multi DOF Local Electromagnetic Actuation for Robotic Abdominal Surgery

    Get PDF
    This paper aims to characterise the magnetic interaction in neighbouring sets of local electromagnetic actuation (LEMA) actuators in a robotic platform for abdominal surgery. The analysis looks into the affect of the magnetic fields contributed by a stator-rotor set (the actuation unit) located adjacent to the rotor of interest. Each rotor drives one of the degree-of-freedoms (DOFs) on a surgical robotic device. In this study, a two-DOF setup is used for the magnetic interaction analysis, which can be expanded to general case n-DOF setup with the Principle of Superposition of magnetic fields from multiple sources. The magnetic model is then used to compute the dynamics of the system, which involves the equation of motion of the rotors and associated robotic mechanism it drives, and the actuator (electrical) model that takes into account the back EMF generated by the permanent magnet rotors. The magnetic field effect of the neighbouring set onto the rotor is observed by obtaining the speed response of the rotor through simulation so that the dynamic model can be validated against the experimental results. The outcomes are useful for the design specification of the LEMA system configuration, involving the feasible / pragmatic distance between the stator sets such that the interference is minimised, and for the design of the necessary control strategy

    Speed Control of Non-collocated Stator-Rotor Synchronous Motor with Application in Robotic Surgery

    Get PDF
    This paper introduces Non-collocated Stator-Rotor Synchronous Motor (NSRSM) as a novel actuation system for cases where the stator and rotor are required to interact across a physical barrier. The main motivation for NSRSM is in the area of laparoscopic robotic surgery whereby it is desired to actuate the manipulators across the abdominal wall, but it also has potential application in other robotic surgery procedures. The configuration of NSRSM is similar to that of permanent magnet synchronous motor (PMSM) although due to asymmetric structure of the windings around the rotor, the electromechanical model of PMSMs was developed to obtain the dynamic model of NSRSM. The field oriented control method is used to develop an appropriate model for control purposes. Then two widely used control algorithms (PI controller and linear quadratic regulator (LQR)) are used to control the rotor speed in the presence of the modelling uncertainties and load disturbances. Simulation results show that these two methods are robust

    Disturbance Rejection in Multi-DOF Local Magnetic Actuation for Robotic Abdominal Surgery

    Get PDF
    The potential of multi-degrees-of-freedom (DOFs) local magnetic actuation (LMA) has been established in recent years for dexterous minimally invasive surgical manipulations. Nonetheless, having multiple magnetic based units, one for each DOF, within a close vicinity to each other leads to magnetic field interaction among the magnetic sources, hence, resulting in a disturbance to a given LMA unit. It is further realized that the disturbance is a result of actuation effort by the neighboring magnetic sources forming the LMA units, and that the actuation command to all LMA units is a known information to the controller. Therefore, partial information of the disturbance is known and can be exploited in a disturbance rejection strategy. In this letter, this disturbance is modeled and used to augment a simplified model of the systems dynamics of the LMA-based surgical manipulators. The internal model principle (IMP) strategy is selected in which an observer is designed to estimate the disturbance to be rejected. Numerical simulation as well as experimental validation were performed to validate the efficacy of the IMP. The results serve to remove a significant technical hurdle in bringing the new emerging technique of LMA into practical reality for abdominal surgeries

    Magnetic Surgical Instruments for Robotic Abdominal Surgery.

    This review looks at the implementation of magnetic-based approaches in surgical instruments for abdominal surgeries. As abdominal surgical techniques advance toward minimizing surgical trauma, surgical instruments are enhanced to support such an objective through the exploration of magnetic-based systems. With this design approach, surgical devices are given the capabilities to be fully inserted intraabdominally to achieve access to all abdominal quadrants, without the conventional rigid link connection with the external unit. The variety of intraabdominal surgical devices are anchored, guided, and actuated by external units, with power and torque transmitted across the abdominal wall through magnetic linkage. This addresses many constraints encountered by conventional laparoscopic tools, such as loss of triangulation, fulcrum effect, and loss/lack of dexterity for surgical tasks. Design requirements of clinical considerations to aid the successful development of magnetic surgical instruments, are also discussed

    A PRAGMATIC ANALYSIS OF MAXIM FLOUTING UTTERED BY THE CHARACTERS IN MUCCINO’S PURSUIT OF HAPPYNESS MOVIE

    This study focuses on maxim flouting uttered by the characters in Pursuit of Happyness movie. This study is aimed at (1) identifying the types of maxim flouting in Pursuit of Happyness movie and (2) describing the strategies of maxim flouting uttered by the characters in Pursuit of Happyness movie. This study applied qualitative research method. The data served as Pursuit of Happyness movie script. This study applied note-taking to collect data technique. The procedures of data analysis (1) identified the data which the researcher assumed as maxim flouting, (2) coded the data into data sheet, (3) re-checked the accuracy of the data findings, and (4) interpreted the data findings in order to answer the research question, and (5) made a conclusion of the data. The results of the data analysis show two important findings. First, the researcher finds four types of maxim flouted in the movie. They are maxim flouting of quantity, quality, relation, and manner. Maxim flouting of quantity ranks first because the characters deliberately gives more information than is needed within a conversation. Second, there are ten strategies of maxim flouting found in the movie. They are tautology, overstatement, understatement, metaphor, hyperbole, irony, banter, sarcasm, changing topic, and being not brief (obscure). The highest occurrence of the strategy used to flout maxim is overstatement strategy. On the grounds that overstatement is commonly used to pursue people to accept the speaker’s idea. Key words: Pragmatics, Maxim Flouting, Muccino’s Pursuit of Happynes
