Abstract

In mushroom cultivation of white oyster mushroom (P. ostreatus), problems in the contamination during the production are typically found. This contamination is due to the issue in controlling temperature during the media sterilization for growing the fungus (bag-log). This suboptimal sterilization causes unwanted bacteria and spores to grow. To reduce the amount of contamination, the purpose of this study was to demonstrate and evaluate the temperature distribution using one convection pipe with diameter of 6 and 8 cm. The fuel used for this sterilization process is rice husk. Sterilization itself aims to kill other unwanted bacteria and spores on the bag-log. Sterilization was done by traditional steaming bag-log drums arranged in four rows upwards for 6 hours. Convection pipes were built in drums. The steamer was done by performing two retrievals of data. From the experiment results, the use of convection pipe of 8 cm was better than the convection pipe of 6 cm. This is shown from the amount of fungal contamination in convection pipes were less in 8. The result of temperature measurement using dual laser infrared thermometer was also completed and interpreted using Matrix Laboratory with interpolation method to get heat distribution result.

Abstract

The changing times that followed the development of technology made the education system management must be updated to suit the needs and conditions of the environment. In this article, we look for information about the education system in two different countries, namely Japan and Indonesia. The purpose of this research is to find out the integration between the two countries that have different education management systems. The research method used is a descriptive qualitative method. In this research also, the research method is based on the philosophy of postpositivism, using natural conditions or objects. The instrument used to find out information on the education system in each school uses 10 questions and looks for curriculum information data in general in each country. The findings in this study found that, although the management of the education systems of the two countries was slightly different, Indonesian students could compete to continue their tertiary education to developed countries. Besides, the education system in Japan does not make students from Indonesia experience difficulties.

Abstract

In this study, the researchers measured cicadas' sound waves, considering that cicadas are mostly found in rural areas. The intensity level meter (AMTAST AMF003) was used with time variations (9:00 JST; 12:00 JST; and 15:00 JST). Measurements of air temperature differences (Krisbow Temperature & Humidity Data Logger) were also carried out, and weather conditions were also considered in data collection using satellite data from Himawari, Japan. The interpretation results of intensity level's trend measured at 3:00 pm JST were decreased concerning the changes in days. Meanwhile, the measurement at 09:00 am and 12:00 pm JST did not show a decrement concerning the changes in days (31 days in total). These results show that temperature changes (towards autumn) can affect the intensity level of sound waves. In addition, slightly different intensity levels can affect large changes in acoustic power or the produced sound.

Abstract

This study aims to gather information about the needs of elementary school teachers in the application of effective mathematics learning. This research is part of a research entitled Development of Learning Videos Based on Contextual Teaching and Learning Approaches to Improve Student Learning Outcomes of Primary Schools in Palembang City. The method used is research and development in the form of survey data. The survey method was carried out using a questionnaire in the Google form on 39 teachers in Palembang. The results of the distribution of the questionnaire interpreted that elementary school teachers were in dire need of media, especially in the form of contextual based mathematics learning videos. The conclusion of this research is the need for the development of learning videos to facilitate teachers in teaching contextual mathematics so that it will have a good impact on learning outcomes of elementary school students.

Abstract

Robotics technology is known as a great technology demand to be developed continuesly. One of the important things that need to be considered is the control of the motion of the robot. Movement predictions can be modeled in mathematical equations. Prediction based on learning logic is also very supportive of motion control systems, especially arm motion. In this study, the authors combined the two methods as the main study. The working principle of the arm is to take colored objects detected by the camera. In this study, we made arm four DOFs (Degree of Freedom), but only one DOF is controlled by ANFIS because the other three DOFs only move at two fixed angles. Two methods of determining the arm angle of motion used are inverse kinematics and ANFIS methods. The angle of motion and the position of the red object can be observed in real-time on the monitor with the interface in the MATLAB GUI. The angular output that appears in the MATLAB GUI is sent to Arduino in the form of characters, then, Arduino translates it into servo motion to the coordinates of the object detected by the camera. The results showed that the ANFIS method was more effective than the inverse kinematics model.
