Di Indonesia, penelitian mengenai Jamur masih belum banyak dilakukan. Hal ini membuat minimnya informasi tentang keanekaragaman Jamur, sehingga perlu adanya kegiatan eksplorasi. Oleh karena itu, penelitian ini dilakukan untuk menginventarisasi Jamur makroskopis khususnya di jalur pendakian Kawah Ratu Taman Nasional Gunung Halimun Salak (TNGHS). Penelitian ini menggunakan metode jelajah. Data yang diamati meliputi data primer dan data sekunder. Identifikasi Jamur menggunakan alat bantu berupa buku identifikasi, jurnal yang relevan, aplikasi, dan website identifikasi Jamur. Hasil penelitian menunjukkan bahwa di kawasan jalur pendakian Kawah Ratu TNGHS terdapat 59 spesies Jamur dari 2 divisi yang berbeda, yaitu Divisi Ascomycota yang meliputi satu famili dan 2 spesies, serta Divisi Basidiomycota yang meliputi 18 famili dan 57 spesies.

Pusat Pendidikan Konservasi Alam Bodogol (PPKAB) wilayah sekitar 2.600 ha (26 km2) merupakan bagian dari Taman Nasional Gunung Gede Pangrango. Tumbuhan lumut Bryophyta merupakan tumbuhan tingkat rendah yang banyak dijumpai di daerah tropis. Penelitian ini bertujuan untuk mengetahui keanekaragaman lumut (Bryophyta) di kawasan Pusat Pendidikan Konservasi Alam Bodogol. Penelitian ini merupakan penelitian eksploratif yang dilaksanakan mulai Januari – September 2021. Penelitian ini dilakukan pada empat stasiun pengamatan menggunakan metode jelajah dengan teknik pengambilan data secara purposive sampling. Parameter lingkungan yang diukur diantaranya suhu, kelembaban udara, pH tanah dan intensitas cahaya. Berdasarkan hasil penelitian didapatkan hasil sebanyak 21 spesies yang termasuk kedalam 15 famili yang terdiri dari tiga kelas dengan jumlah sebanyak 1466 individu. Jenis tumbuhan lumut terbanyak ditemukan di kawasan PPKAB adalah Barbula indica dari famili Pottiaceae dengan jumlah 295 individu. Indeks keanekaragaman pada semua stasiun pengamatan tergolong sedang, indeks kemerataan semua stasiun berada pada kategori tinggi dikarenakan pertumbuhan yang tumbuh beragam dan merata dan indeks dominansi berada pada kategori rendah hal tersebut dikarenakan nilai indeks yang mendekati nol sehingga tidak adanya spesies yang sangat mendominasi pada setiap stasiun pengamatannya.

The Javan Eagle Wildlife Sanctuary Center (PSSEJ) is one of the regions in Indonesia that has a high diversity of flora and fauna in Bogor, West Java. One of the fauna that live in PSSEJ is an insect of the order Lepidoptera. The limited information about Lepidoptera in this location causes the data on the diversity of these species to not be known with certainty. It is necessary to research the diversity of Lepidoptera. This study aims to study the species diversity of the order Lepidoptera at the Javan Eagle Wildlife Sanctuary Center. This research is an exploratory research conducted from December 2020 to August 2021 in two routes, namely track 1 (camping ground area) and route 2 (officer entrance route and land use). The research method uses a survey method using a sweeping net technique. Collecting data in the form of primary data covering the number of Lepidoptera species and secondary data covering temperature, humidity and light intensity. Based on the research, it was found 39 species of the order Lepidoptera with a moderate diversity index of 2.84, a high evenness index of 0.87 and a low dominance index of 0.08.Â Keywords: Diversity, Javan Eagle Sanctuary Center, Lepidoptera

The development of 21st century science and technology in the field of education requires students to be able to master the 4C skills, one of which is critical thinking. Critical thinking skills can improve students' ability to solve problems, draw conclusions and find appropriate solutions from various aspects and perspectives they will face. PBL-based student worksheets and PBL learning models are the right choice to improve critical thinking skills and can be linked to SDGs problems which will later make students solve various problems to be able to achieve SDGs goals and targets. This study aims to analyze the improvement in aspects of students' critical thinking skills after applying PBL-based student worksheets on SDGs problems. The research was conducted at a public high school in Bogor Regency, while the method used was a experiment. The population that was used as the object of research was students in several public high school classes in Bogor Regency, with cluster random sampling taking the sample. Based on the results of research and analysis, it shows that PBL-based student worksheets can improve students' critical thinking skills in SDGs problems, seen from the N-Gain score in the experimental class of 0.48 and the control class 0.32 in the medium category. The activeness of the students in the class which was assessed through the attitude and skill aspects, showed that the experimental class was higher than the control class which affected the improvement of students' critical thinking skills. The conclusion of this research is that the alternative research hypothesis is accepted, so that there is an influence of PBL-based student worksheets on SDGs issues to improve students' critical thinking skills.

ABSTRACT: Soybean husk is waste from the tempe making process which contains organic materials and nutrients so that it can be used as raw material for making organic fertilizer. The use of organic fertilizer on vegetable plants is one effort to meet the need for organic vegetables. This research aims to obtain information on the nutrient and heavy metal content of liquid organic fertilizer for soybean epidermis and the effect of this fertilizer on the growth and yield of pak choy. This research was carried out in December 2022-July 2023, in Citeureup, Bogor and the Laboratory of the Faculty of Agriculture, IPB University. The experimental design used was a Randomized Block Design with three replications. The liquid organic fertilizer treatments used consisted of control, 5%, 10%, 15% and 20%. The parameters observed were plant height, number of leaves, leaf area and plant wet weight. The results showed that liquid organic fertilizer from soybean epidermis contained C-organic (1.63%), C/N ratio (20.13), macro nutrients (N+P₂O₅ +K₂O) 0.42%, total and available Fe (26.61ppm and 25.56 ppm) and Zn (0.42ppm). The heavy metal content (Pb, Cd, Cr, As, Hg) meets the quality standards set by the Minister of Agriculture of the Republic of Indonesia No. 261 of 2019, so that it can be applied to plants. Liquid organic fertilizer with a concentration of 5% was the best supporting growth and production of Pak Choy compared to the control, 10%, 15% and 20%.

The study of Gastropod diversity in Cibuaya is very important, since Gastropods are the most important organisms in the food chain in aquatic ecosystems. To understand Gastropods, students need electronically supported learning aids in the form of e-booklet. One of the very important roles of e-booklets students can access e-booklets anytime, anywhere on their devices. The aim of this research is to develop a research-based electronic booklet for the identification of gastropod diversity, based on the findings from the identification of gastropods at Cibuaya Beach, Sukabumi. The development method used in this research is the 4-D model, which includes definition, design, development, and dissemination. This research was realized by developing the research results into an electronic brochure on gastropod diversity at Cibuaya Beach, Ujung Genteng, Sukabumi. Validation of the e-booklet was carried out by three Lecturers who were experts in material content, language, and media, and three Biology teachers to validate regarding the content of the material which is adapted to the material at school . The results of the validation test produced an average score of 86%. This score indicates that the E-booklet learning support falls into the very viable category and can be used in learning activities.
