Abstract

Subak is a traditional organization owned by the Balinese people to manage rice field irrigation. In the process of irrigating the fields, subak administrators and farmers check the condition of the irrigation in the fields by directly coming to the location to check the condition of the water level in the fields, so it is time consuming and less efficient. The creation of a geographic information system is intended so that subak administrators and farmers know the water level of the fields and regulate irrigation without going to the fields. The geographic information system is built using the Laravel framework equipped with a map. The map was created with the Google Maps API with the aim of displaying the location of rice fields. The result of this research is a geographic information system that can monitor the height of rice fields and display data on a map. The information system can also receive sensor data and send configuration data to Antares. In black box testing, the information system has been running according to the functions and scenarios given. Based on the results of the System Usability Scale test, the application obtained a score of 76,125 which indicates the application is classified as good and can be accepted by the user.

Abstract

Some studies such as Aoki measure clock skew by filtering outliers by selecting the minimum offset that is collected using linear regression to calculate the slope of the accumulated minimum offset. Huang who uses the QPM (Quick Piecewise Minimum) algorithm to calculate the skew of the minimum offset at the beginning and end of the collected offsets and Moon's research that uses the LPA (Linear Programming Algorithm) algorithm which determines the clock skew of the line gradient that is below the offset. In addition, there are several methods that have the potential to be used in measuring clock skew including ant colony, bee colony, particle swarm, and also genetic algorithm. From these several methods, one method that has potential as a method that can be used for measuring clock skew will be selected. The method that can be used is particle swarm optimization because it is considered more efficient and flexible and easy to implement with few parameters used.

Abstract

OFDM is a transmission technique using orthogonal multi-carrier which can save bandwidth. While MIMO is a technique of using more than one antenna for transmitting and receiving. This can increase data transmission capacity without increasing bandwidth. In this study, an analysis of variations MIMO antennas 2x2, 2x4, 4x2, and 4x4 was carried out to determine the effect of antenna variations on OFDM MIMO performance. The modulation are BPSK and QPSK with frequency selective fading and AWGN channels. Performance parameters are Bit error rate (BER) versus Energy Bit per Noise (Eb/No), Power to Average Peak Ratio (PAPR), and eye diagram. The model simulated using a simulink with a number of input 100,000 bits. The results showed that BER performance compared to Eb/No, in MIMO 2x4 and 4x4 produced better performance than MIMO 2x2 and 4x2. With many receiving antennas, it gets a better signal which can reduce the occurrence of errors. Meanwhile, in PAPR parameter, 4x2 and 4x4 MIMO produce higher PAPR values than 2x2 and 2x4 MIMO. With the number of antennas, the PAPR value is distributed over all antennas and increase the PAPR value in the system. In the eye diagram parameters, the greater the Eb/No value, make a better eye diagram.

Abstract

The project-based learning model is one of the strategies used to increase student engagement and motivation, especially in supporting the development of character education. However, in its application, project learning faces challenges such as taking a long time, causing students to feel bored, and not all students are fully and evenly active in the learning process. This has an impact on the non-achievement of learning objectives in the development of character education. This study aims to identify the factors needed to improve the quality of project learning implementation for character education development. The strategy analysis used in the study uses external as well as internal factors analysis with SWOT and AHP (Analytic Hierarchy Process). The method used in this study is a mixed method with an exploratory sequential design, which collects data qualitatively, namely through interviews and observations, which are then followed by quantitative analysis by distributing questionnaires to respondents. The results show that internal factors, namely innovative and digitalized school management, are the main strengths in implementing project learning for character education development. On the other hand, external factors show significant opportunities for driving schools to support this learning while considering external threats. The top priority strategy recommended in character education development is to utilize technology for innovative learning that increases student engagement. This strategy aims to provide space for students to make progress in cognitive, affective and psychomotor aspects. The main focus in project learning is to ensure students are actively engaged, so an innovative, technology-based approach is needed that allows students to explore, think critically and develop themselves.
