Malaysia has introduced 21st-century learning initiatives through the Malaysia Education development plan 2013-2925. Among the focus are learning, teaching, and facilitation (TLF) by teachers in schools. This study aims to understand the knowledge, attitude, and practice of 21st-century education among teachers in the Rompin District, Pahang. This study employs a quantitative approach with the help of a questionnaire. The sample comprised 152 school teachers with simple random sampling techniques. This research employed a descriptive analysis and inferential analysis (Pearson correlation, t-test. The findings showed the moderate level for knowledge (M=2.95, SD=0.22), attitude (M=2.94, SD=0.23) and practices (M=2.90, SD=0.29). The t-test showed a significance difference between knowledge (t=-2.11, df=157, p<0.05) and attitude (t=-2.26, df=157, p<0.05) while there are no significant differences in practice (t=-1.81, df=157, p>0.05). Pearson correlation analysis showed a modest positive relationship between knowledge and practices (r=0.677, p<.01) and a high positive relationship between attitudes and practices (r=0.837, p<.1). In conclusion, the knowledge, attitude, and practices level are moderate among teachers. So, teachers need to improve their 21st-century education from time to time with, among others, short courses. Help from the obligatory authorities and academicians will increase teachers' awareness of 21st-century learning in their lives. This study's implications showed that 21st-century education literacy among teachers can increase the teachers' knowledge, attitude, and practice and always use 21st-century education in their teaching process.

In rural areas of Sabah, Malaysia, the groundwater source is the only water supply for domestic consumption. Therefore, the monitoring of groundwater quality is essential to adhere to the standards by Malaysia's Department of Environment. This article seeks to evaluate the groundwater quality through the quantitative analysis, and the sampling carried out between January and March 2019. Among national water quality standards sampled including dissolved oxygen, pH, ammonia nitrogen, and total suspended solids. The result showed that the chemical oxygen demand was above the standards, >197mg/l (Station 5) and fall into Class V. However, the index of water quality for all stations indicate Class II with the lowest in Station 5 (80 per cent) and the highest in Station 6 (90 per cent). All stations showed clean category except for Station 5 (moderately polluted). This study also implicates that the water quality assessment could act as a tool in monitoring the groundwater.

This study aims to look at the effectiveness of Geography fieldwork study among form six students in Machang, Kelantan. A quantitative approach was applied in this study by using a questionnaire as an instrument. A simple random sampling method was used for the selection of respondents and the total number of respondents was 80 form six students who were taking Geography in some selected schools in the Machang district in Kelantan. Four study variables were used, namely interest, understanding, skills and effectiveness, in the implementation of the Geography fieldwork study. Descriptive analysis was used to examine the level of each variable I, II, III and IV, and inferential analysis (Pearson's correlation and regression) was used to examine the relationships and influential contributions of each study variable. The findings showed that all of the variables, namely interest (M = 2.89, SP = 0.32), understanding (M = 2.87, SP = 0.32), manipulative skills (M = 2.33, SP = 0.50), soft skills (M = 2.75, SP = 0.44) and the effectiveness of the implementation (M = 2.90, SP = 0.30) were at a moderate level. The results of the Pearson's correlation analysis also found that there was a significant positive relationship between the interest and understanding variables (r = 0.538, p <0.005), understanding and manipulative skills (r = 0.556, p <0.005), manipulative skills and soft skills (r = 0.595, p <0.005) and soft skills with effectiveness (r = 0.677, p <0.005). In addition, regression analysis showed that soft skills had the highest impact on the effectiveness of the Geography field study by 45.8% with R2 = 0.581, F (26.030) = 0.324, P<0.05. In conclusion, this study finds that students show an interest, understanding, and skills in the effectiveness of the Geography field study. This shows that the implementation of Geography field study in schools can bring about change among students, and indicates that an effective Geography field study can enhance students' interest, understanding and skills in the subject of Geography and is able to give students the opportunity to be more innovative and to think creatively.

The combination between DS18B20 Waterproof temperature sensor and Arduino has been recently used as a data acquisition (DAQ) system on a temperature measurement for its user-friendly and relatively affordable price. Arduino can be a valid data acquisition device if the sensor is perfectly calibrated. This research proposed a calibration method for a temperature sensor DS18H20 Waterproof based on Arduino Uno using a thermometer calibrator ASTM 117C which value could be traced by a calibration medium of oil in an open surface bath. The election of oil as the medium is aimed to reduce its conditional instability so that the calibration could be done. There are 12 arranged DS18B20 waterproof sensors that will be calibrated alongside the ASTM 117C calibrator so that all the measurement points have the exact identical conditions. Such a system was done for having the small deviation characteristics between the oil temperature measured on the DS18B20 Waterproof sensor to the ASTM 117C mercury thermometer. The small deviation characteristics that presented as a linear equation is obtained by using a linear regression method. Calibration was done by using the ambient temperature as the energy to calibrate the sensors. The movement of ambient temperature will cause temperature slowly movement response on the medium (oil) and resulted a measurement points. DS18B20 waterproof sensors resulted a mean error of ± 3.00 % before calibration begun. Meanwhile after the calibration using the proposed method, the DS18B20 sensor has a smaller mean error of ± 0.85 %, so that obtained a more accurate sensor and it can be used for testing of Grashof Portable Incubator made by University of Indonesia.
