In 2020 the Covid-19 pandemic has become a global problem and has an impact on all aspects of life, including education. The learning process in all educational institutions, both formal and non-formal, was affected by the Covid-19 pandemic. One of the educational institutions affected by this pandemic is the Al-Qur'an Education Park (TPQ). The Covid-19 pandemic made the government try to suppress the spread of Covid-19, with that the government issued a policy to all educational institutions to close, then switched to Distance Learning (PJJ) and Learning From Home (BDR). Many of the educational institutions carry out an online learning process (online), but not all levels of society are able to adapt to the online learning process, especially those in rural areas. So this research aims to obtain information about the impact of the Covid-19 pandemic on the learning process at TPQ. This research uses a qualitative approach with a case study method. In this study, 5 respondents were selected, namely TPQ teachers in Kutelintang Village, Blangkejeren District, Gayo Lues Regency. The results of this study obtained information that the learning process at TPQ took place face-to-face, and generally the learning process at TPQ was less effective because there were too many holidays. So that it has an impact on students, teachers and parents. In addition, TPQ also played an important role in disseminating the Covid-19 pandemic to students.
This article presents measurement data using environmental magnetism method on the bulk surface sediments related to the research article entitled “Heavy metal contents and magnetic properties of surface sediments in volcanic and tropical environment from Brantas River, Jawa Timur Province, Indonesia” Mariyanto et al., 2019. Surface sediments were taken from 20 different locations along Brantas River. In the laboratory, a series of magnetic measurements was conducted on sediment samples i.e. magnetic susceptibility, ARM (Anhysteretic Remanent Magnetization) and IRM (Isothermal Remanent Magnetization). These environmental magnetism data were used to characterize bulk surface sediments in the study area.
Mangroves have been investigated widely as plants that can absorb and accumulate heavy metals in their tissues. Due to that ability, mangroves have been used to reduce heavy metals in the aquatic environment. Furthermore, mangroves have been used for biomonitoring of heavy metals pollution. The use of mangroves for biomonitoring on aquatic environments has been considered as a cheap, rapid, and sufficient method. The mangrove is an organism that has the ability to absorb the contaminants of heavy metal and to function as fine pollutants trap. However, to develop this technique for wide use, research and investigation are still needed. This paper is aimed to describe the future direction of mangrove studies of using mangroves as a biomonitoring agent. Based on the review, Rhizophopora mucronata and Avicennia marina are mangrove species that have a promising ability to be used for biomonitoring in the aquatic environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
