<![CDATA[In medical physics, the simulation of radiation dose distribution in the body of radiotherapy patients is generally carried out using the Monte Carlo method. But in conducting this simulation, medical physicists are often faced with the incompatibility problems of phantom geometry with simulation needs. Phantom ORNL-MIRD is the most commonly used phantom in simulation. In a radiotherapy simulation, cancer cells are usually only assumed to be in the phantom’s body without any concrete form. This can cause the administration of radiation doses that are not right on cancer cells. Phantom ORNL-MIRD is also only composed of three materials, namely bone, lung, and the rest are considered as soft tissue. This certainly provides inappropriate simulation results, especially in the case of breast cancer radiotherapy where the breast is composed of adipose tissue. This study aims to make ORNL_MIRD phantom modelling suitable for the needs of Monte Carlo simulations of breast cancer patients. The phantom modification will be carried out on the soft tissue structure of the breast and the structure of the skin tissue. Cancer cells with a diameter of 2 cm were also added to the left breast at a depth of 2.5 cm. The γ rays from radionuclide 60Co with the energy of 1.1732 MeV and 1.3325 MeV and the probabilities of 0.989 and 0.998, respectively, were exposed to the phantom. The simulation results show that there are significant differences before and after modification. Absorption dose values in the breast with a soft tissue without tumour cells were 0.31 mGy with a relative error of 0.0023, while the absorbency dose rate in the breast with soft tissue and tumour cells was 0.2 mGy with a relative error of 0.0023.]]>

<![CDATA[Substrate integrated waveguide (SIW) is a technique to implement waveguide into microstrip material that can be applied to filter, antenna, mixer, coupler, and so on. Implementation of SIW to filter can overcome the problem of size reduction and high insertion loss commonly used in a conventional filter. While the complementary split ring resonator (CSRR) method overcomes the problem of size reduction and selectivity in conventional filters, thus combining the two can provide better filter performance. This research proposes both methods in realizing a bandpass filter by using a parameter study. Bandpass filter design works on a frequency of 3.4 – 4.6 GHz with an insertion loss value of 0.5 dB and a return loss value above 15 dB and has one transmission zeros at the frequency of 3.32 GHz. While the measurement results provide an insertion loss value below 3 dB and 6.5 dB return loss.]]>

<![CDATA[The use of solar panels to get electrical energy from solar energy is one effort to utilize renewable energy resources. Solar panels (solar cells) are instruments that can convert the energy of sunlight into electrical energy. Solar panels are not only used in homes or in certain places, but also in large transport equipment such as cars and on ships. Solar panels are mostly installed in a stationary or static position. Whereas the direction of sunlight will change its angle relative to the surface of the solar panel. The change is increasingly irregular if the vehicle where the panel is located moves in the direction you want to go. Conditions like this cause the absorption of solar energy by solar panels to be less than optimal. In this research, a system has been designed where the solar panel was always controlled so that the direction of sunlight always falls perpendicular to the surface of the solar panel even though it was in a changing location and the direction of the sun's light on the earth's surface was always changing. Solar panels that can maneuver in two axes of motion were controlled by a microcontroller and two servo motors as actuators to adjust the position of the solar panel so that the surface was always perpendicular (following) the direction of sunlight. From the results of the tests, it turns out that solar panels in this research design can produce power 6.51% greater compared to static solar panels output.]]>

<![CDATA[Renewable energy implementation could become the alternative for electrical energy supply in a remote area with no network for electricity and also could be implemented in an urban area to reduce electricity consumption in daily usage. One of the problems to implement renewable energy is how to measure solar power potential and wind power potential to decide the qualification to apply the system in a particular area. This research used Arduino Uno as the main Controller that connected to a Voltage sensor, Current Sensor ACS712 30A dan light intensity sensor BH1750 to measure solar power potential and also anemometer to measure wind power potential. Software design was done using Arduino IDE program that successfully produced stable Low-Cost system that can operate well with all kind of solar panel with maximum Voltage of 34.7 V and current ± 30 A. The results from system testing shows that the system has accuracy for voltage sensor with value of 99.2%, current sensor with value of 95.3% and light intensity sensor with value of 99.8% and also has excellent precision with SDR value for every sensor are 0.034%, 4.58% and 0.026%.]]>

<![CDATA[Water condition is the main factor that affects the success rate of aquaculture, especially in shrimp cultivation. However, the farmer often experiences difficulties in determining the condition which is stated based on the measurement of various water parameter. Therefore, a proper classification model is needed to help the farmer in classifying the water condition in a pond. By knowing the condition, then proper and correct treatment can be given. In this research, a machine learning algorithm called SVM is used to make a model from an aquaculture dataset. Another processing technique like data normalization and the usage of optimization algorithm named grid search is also performed to improve the modelling result. Furthermore, a test scheme with using k-fold cross-validation is performed to know the performance of the model which is measured by the value of accuracy, precision, recall, f-measure, and AUROC. Then, the SVM model is compared with several models which are made by using another machine learning algorithm such as KNN, CNB, RF, MLP, and LR in order to know the best model to be implemented on cultivation process. From the experiment results, the model which is made with SVM and grid search optimization has the best performance in the validation process with the performance score of 3.54383.]]>

<![CDATA[The photovoltaic grid-connected business opportunity offers challenges to power quality and voltage fluctuations in the distribution system. The purpose of this study is to optimize the location and power capacity of the grid-connected photovoltaic so that the voltage values are in accordance with the operating standards and meet the requirements of the connection techniques in the distribution system. The distribution system tested is the 69 Buses radial distribution feeder. The optimization uses three constraints namely voltage constraints, active power capacity constraints and total active power capacity constraints of the Grid-Connected Photovoltaic. The Optimization is carried out by considering the value of the percentage of the total active power of the Grid-Connected Photovoltaic capacity to the total load in the distribution system. The optimization results in the first simulation indicated seven grid locations with a total active power of 1.156 MW (38% PV) and produced a fitness value of 0.029. The second Simulation showed 7 locations with a total active power of 1.243 MW (41% PV) and produced a fitness value of 0.023. The Third simulation was identified with 11 locations with a total active power of 1.385 MW (46% PV) and produced a fitness value of 0.022. The best fitness value is the lowest value of the active power losses. The entry of a number of the Grid-Connected Photovoltaic System with distributed location can increase the voltage level in the distribution system.]]>

<![CDATA[Developing technology can facilitate work activities, one of which is technology in the field of robotics. One of the purposes of creating the robot was to assist in investigating suspected targets. The target can be a gas source leak object. On the other hand, gas leaks in industrial estates have a large impact on the environment. Robots are needed to facilitate the inspection process of targets suspected of gas leakage. Robots generally have systems that are integrated with sensors as interfaces and intelligent computing. In this study mobile robots and manipulators have been designed and have the purpose of inspecting objects suspected of being gas leaks. This robot system is called a mobile robot manipulator equipped with a wireless camera for object detection, two gas sensors for aroma detection, each sensor is mounted on the end-effector manipulator and next to the camera. The methods used in robots are fuzzy logic and cubic trajectory. Fuzzy logic is used to navigate robots to objects, and cubic trajectory for navigating manipulators based on the specified route. In the experiments that have been done, the mobile robot can navigate to the target until it stops at a distance of 20cm, and the manipulator is also successful in navigating. In the testing instrument, two leaking points have been determined. Each point is tested six times. The robot succeeded in detecting gas leaks with a success rate of 91.67%, and the position of coordinates read by the manipulator can be observed through the monitor.]]>

<![CDATA[Paralysis is a disease that can limit the mobility of the sufferer. One solution that can help people with paralysis in carrying out their mobility is the use of an electric wheelchair. In this study, an electric wheelchair with specifications where the wheelchair motion control uses muscles on both arms, so that the electric wheelchair is very suitable for patients with paralysis in the legs and weak hand strength in turning the wheels from the wheelchair. The input of motion control commands is carried out through an electromyograph sensor mounted on the flexor muscle in both patients’ arms. The output of each sensor is given a threshold of 2 volts to distinguish control commands or not. When the sensor output is more than the same as the threshold, it is considered logic one and the other is considered logic zero. The method is used to interpret the output as a control command by impulse detection. The electric wheelchair movement that can be done is forward, turn right, and turn left.]]>

<![CDATA[The postpaid KWH Meter reading by officers is sometimes constrained to reach the physical KWH Meter because the house fence is locked or the KWH Meter is inside the house. This often causes problems such as reading errors and the officer must come to the customer several times. Therefore a telemonitoring system for KWH Meters is made through an online WiFi network to help officers record electricity usage for consumers. This system uses ACS712 current sensor, ZMPT101B voltage sensor, different phase sensor, RTC DS1307 as a timer and date, Arduino as a data processor, Micro SD Card for storing date, time, and sensor readings, LCD as a viewer, and transmitted with modules ESP8266 Wi-Fi to a smartphone or PC with a simple web display. The test results show that all components can function properly. ACS712 30A current sensor has an average error of 1%, and the ZMPT101B voltage sensor is capable of carrying out voltage readings in load or no load conditions with an average error of0.5% and a different phase sensor has an average error of 1% for resistive load and 4.2% for inductive loads of TL lights. Power measurements have an average error of 1.3% for 75W incandescent lamp loads and 300W irons. The ESP8266 Wi-Fi module emits a maximum of 15 meters when not blocked and 10 meters when blocked. All measurement data can be stored on the SD Card.]]>
