“…Data from the water quality algorithms are then tested for validity by comparing the results from two different satellites in the same year. Validity test using the Spearman Rank correlation (Equation 1) because all the results of the processing have non-normal distribution (Setiawan et al, 2019). Data prove to be valid as indicated by the minimum significance value of 0.05, thus analysis can be continued using the Mann-Whitney U-Test as presented in Equations 2 (Dadson, 2017;Milenovic, 2011;Sanyé-Mengual et al, 2018).…”

The presence of Cirebon coal-fired power plant I and II caused negative effects to coastal morphology and the quality of marine waters. This also have negative impacts to the fisherman around that sea. This study aims to examine the impact of the Cirebon coal-fired power plant on the water quality of Mundu Bay, Cirebon Regency. Water quality is determined based on total suspended solids (TSS), sea surface temperatures (SST), chlorophyll-A, and salinity in the range 1999 – 2019. Data collection was carried out using satellite imagery of Landsat-5 TM, Landsat- 7 ETM+, and Landsat-8 OLI verified with in-situ field measurements, Sentinel-2 A MSI, and MODIS Aqua imageries. Changes in water quality due to the infrastructure of the two power plants are known through the Mann-Whitney U-Test and Spearman’s correlation analysis. This research shows that two Cirebon coal-fired power plant has a significant effect on changes in the quality of Mundu Bay waters. Changes in water quality are shown by a significant increase in TSS concentrations and SST values accompanied by a decrease in chlorophyll-A levels and salinity levels. Changes in the quality of these waters also disrupt marine biota habitat and cause fishermen in around are difficult to get the ideal catchment yield.

The purpose of this study is to describe alternatives to joy fun online learning using the quizziz application. The research method used is qualitative research. The study was conducted at vocational high school Miftahul Falah, Dawe District, Kudus Regency. Acquisition of data results using indept interviews sent via googleform and key informants to teachers dan students. Based on the results of the study it was concluded that (1) quizziz online learning application is a technology based learning evaluation application that can be accessed online by teachers and students, which is applied during a pandemic in the education sector in order to be able to balance and harmonize learning in school to be always relevant and enjoyable especially in Indonesian language learning content; (2) the existence of the quizziz application provides alternative online learning that can be done without having to face to face directly between the teacher and students and can be accessed outside and in the classroom; (3) quizziz provides advantages for online learning by utilizing learning changes that prioritize learning in the era of the industrial revolution 4.0 using information technology in its delivery, will be more fun, motivating, and attracting the attention of students. Thus, the use of quizziz can make the implementation of online learning no longer make a problem for students and is flexible in accordance with students abilities.

“…Pada kajian ini pengujian mikro sensor DHT11-Arduino dengan data pembanding mengacu pada uji korelasi Spearman Rank (lihat Persamaan 4). Metode ini dipilih karena distribusi data-data tersebut bersifat tidak normal dan diperoleh dengan kaidah purposive sampling [15]. Selain itu, analisis korelasi juga dilakukan secara silang untuk mengetahui hubungan antara suhu dan kelembaban udara relatif di Cikarang Raya.…”

Climatic factors are an abiotic component that determines ecosystem characteristics. Rapid development activities require capable observation instruments and able to provide a variety of weather data to analyze their impact on the environment. This study aims to develop an instrument for measuring temperature and humidity as an essential component of climatic factors based on the DHT11-Arduino microsensor. Tests carried out at 30 scattered points in Cikarang Raya, Bekasi Regency, West Java. Data from the DHT11-Arduino microsensor measurement results are compared with the results of ground measurement and satellite imageries data in the same period through statistical tests. This research shows the DHT11-Arduino microsensor is able to measure temperature and humidity in Cikarang Raya with a significance level of 0.05-0.01. The correlation between microsensor and the comparative data in observing the temperature reached 0.934, while the humidity reached 0.687. The distribution of temperature and humidity of the instruments shows a similar pattern. Using DHT11-Arduino microsensor to observe temperature and humidity has proven to be feasible and able developed to obtain climatic factors data as part of sustainable ecosystem management.
