Mosses or Bryophytes are a group of cryptogamous plants or lower plants. Moss can be found in various places that have high humidity by attaching to various substrates, such as soil, rocks and tree bark. PPKA Bodogol is a potential area that protects endemic flora and fauna on the island of Java that has excellent humidity and air for moss growth and supports moss diversity. This study aims to determine the diversity of mosses and their relationship to environmental factors in the PPKA Bodogol. Data collection in this study was carried out at the PPKA Bodogol on 3 routes, namely Cikaweni, Rasamala and Kanopi. This research uses a purposive sampling method with a cover square technique. The results showed that the total number of moss species identified were 21 species. Then it was also known that the highest level of diversity was found on the Rasamala route with a diversity index of 3.03. In the Cikaweni route, was in moderate category, namely 1,967. The lowest diversity index, however, was in the canopy path with a medium category, namely 1.216. Environmental factors such as humidity, temperature, light intensity, and altitude also had an influence on the level of moss diversity of the three routes.

Praktik pendidikan di setiap jenjang sekolah, selayaknya memenuhi tantangan abad ke-21. Literasi sains merupakan salah satu keterampilan penting yang harus dikembangkan sejak tahap awal pendidikan. Pada penelitian ini, instrumen untuk menilai keterampilan literasi biologi siswa SMP dikembangkan dan divalidasi. Pengembangan instrumen ini menerapkan tahapan model ADDIE. Instrumen ini dirancang berdasarkan kompetensi dasar IPA Biologi kurikulum 2013 untuk kelas VII, dan terdiri dari empat dimensi literasi Biologi. Dari 20 soal yang dikembangkan, terdapat 5 soal berdimensi nominal, 7 soal berdimensi fungsional, 4 soal berdimensi struktural dan 4 soal literasi biologi multidimensi. Uji validitas logis dilakukan untuk isi, konstruksi dan bahasa oleh empat validator, dan dianalisis dengan formula Aiken. Validitas empiris dilakukan dengan uji coba soal kepada 82 siswa kelas VII SMPN 3 Parung Panjang dan dianalisis menggunakan korelasi point biserial. Hasil analisis memperoleh 19 soal valid dan 1 soal tidak valid. Reliabilitas soal diuji menggunakan rumus Kuder Richardson 20, dan diperoleh nilai 0,57 yang berarti instrumen ini cukup reliabel. Tingkat kesulitan setiap soal juga dianalisis, dan diperoleh hasil dengan proporsi 70% soal memiliki tingkat kesulitan sedang dan 30% soal memiliki tingkat kesulitan tinggi.

The ability of Higher Order Thinking Skills (HOTS) is one of the important aspects to solve environmental problems, in this case related to 21st century learning. The purpose of this study is to develop Higher Order Thinking Skills Assessment based on Environmental Problems (HOTS-AEP) in elementary school level. The research method used is research and development model Borg and Gall. The study was conducted in March-April 2019 at State Elementary School of Jatimulya 02, Tambun Selatan, Bekasi, West Java, Indonesia. The results show that HOTS-AEP is suitable for use in learning evaluation because it has a valid category according to experts with an average validation score of 3.63 and valid based on Pearson product moment calculations and has moderate reliability. This is because HOTS-AEP is very compatible with the context of problem-based environmental learning. The conclusion of this study is that HOTS-AEP is worthy of being used as an evaluation of learning for students at the elementary school level.

The purpose of this study was to analyze gender-based biological concepts understanding at secondary school students of bilingual programs. 6 (sixth) problems, according to Bloom's taxonomy categorization, were designed consisted of: understanding, applying, analyzing, evaluating, and creating. The topics included cell, classification of the organism, ecology, plant anatomy and physiology, and human anatomy and physiology. Samples were 47 students from grade nine (secondary school) from one of bilingual secondary schools in Jakarta, Indonesia. Data obtained were analyzed quantitatively and qualitatively. The analysis showed that the average value of the concept comprehension test was 55.07, which was below the Minimum Criteria of Completeness score of 73. The average value of male students was 57.29, and the average value of female students was 52.85. There was no significant difference between the learning outcomes of male and female students. Some male students have higher achievements because they have more engagement in science than others. Students' low ability to understand the biology concept makes them unable to perform their competency at the stages of applying, analyzing, evaluating, and creating. Overall, data showed that the average level of understanding of biological concepts for secondary school of bilingual programs still tends to be low and needs to be continuously improved in the learning process. Hopefully, further studies can be conducted to develop the most appropriate learning method to improve biological concepts.

COVID-19 literacy is very important in dealing with the current pandemic, especially for students who will or are carrying out offline learning. So, it is necessary to develop an instrument that can measure the literacy ability of COVID-19. This study aims to develop an instrument that can assess the COVID-19 literacy level of high school students. The research method used is research and development with Borg & Gall model, which consists of eight stages namely (1) research and initial information collection, (2) designing, (3) developing initial products, (4) expert validation, (5) initial product revision based on input from expert validators; (6) Field trials, (7) revision, (8) implementation and dissemination. The results of the development obtained 28 items consisting of eight questionnaires and 20 multiple choice questions. The questionnaire aims to obtain descriptive data about students' attitudes towards the COVID-19 pandemic, while multiple choice questions are used to measure students' knowledge. The expert test results obtained a score of 3.56 so that the COVID-19 literacy instrument developed was in the very feasible category. In the next stage, the validity of multiple-choice questions was tested and 15 questions were included in the valid category, then the 15 questions obtained were tested for reliability, based on the calculation of the calculated r value greater than r table so that the developed instrument was reliable and could be used in subsequent research.
