An important aspect that needs attention to support success in the learning process is the teacher's competency. One of the key competencies required by teachers is mastery of technology, which supports the development of TPACK (Technological Pedagogical Content Knowledge)-based learning. Additionally, mastery of technology can help develop learning media and serve as a learning aid. One of the software that can be used as an option for learning media is Octave. Octave is open-source software, allowing teachers to access it for free. It can be used as a medium/teaching tool to explain various mathematical concepts, such as functions, function limits, derivatives, integrals, and more. This training was attended by high school teachers and took place at Al Bayan Superior High School, Sukabumi Regency. During the training, participants were taught how to use Octave in mathematics instruction to enhance teacher competency. The results of the training show that the use of Octave can support learning in schools by boosting teacher competency and inspiring teachers to become more professional. This, in turn, leads to improved learning quality in schools, which ultimately enhances the overall quality of education.

The diversity of terrestrial plants in Indonesia are very huge, including production crops such as palm oil (Elaeis sp.), teak (Tectona grandis L.), lemon (Citrus limon L.) and Aloe vera. The quality of production crops is influenced by the diversity of soil microorganisms, namely the Arbuscular Mycorrhizal Fungi (AMF). AMF plays an important role in the growth and development of the host plant. This study aims to determine the diversity of AMF in the rhizosphere of some production crops at SEAMEO BIOTROP, West Java. Research methods are soil sampling and preparation, soil sieving, AMF spore extraction and morphological identification. As a result, spore density tends to be uniform in all four plants (3 spores per 10 gram). The highest to lowest relative abundance percentage of spores on Glomus sp. (52.17%), Acaulospora sp. (34.79%) and Gigaspora sp. (13,04%). Soil, host plant and AMF factors affect the diversity of AMF.

The outbreak of Covid-19 in 2020 has brought downturn to the global economy and many companies went bankrupt during the epidemic. However, according to Unilever's financial report for the first half year, its sales fell only by 1.6% and its financial situation is still stable.
