Abstract

The Kampar River is one of the rivers in the upper reaches that has caused pollution due to local communities such as excessive activity and gravel and sand mining. The purpose of this study was to determine the density of phytoplankton in the Kampar River in Koto Kampar Hulu Subdistrict, Kampar Regency. Purposive sampling was used to determine observation stations, which took into account habitat types and biological parameters observed such as species composition, abundance, and diversity index. The findings revealed that five classes of algae were discovered in Kampar Chlorophyceae, Cyanophyceae, Zygnematophyceae, Bacillariophyceae, and Xanthophyceae. The abundance of phytoplankton in the Kampar River's waters is classified as moderate fertility, ranging from 2,419.96 cells/liter to 3,629.96 cells/liter.

Abstract

The approach to biology learning methods with biodiversity material that explores natural potential such as recognizing regional flora and fauna mascots can be an idea to form positive student characters, one of which is caring for the environment and having pride in regional identity. This study aims to analyze the feasibility and effectiveness of the module as an enrichment of biodiversity material based on local potential through the introduction of regional flora and fauna mascots on the learning outcomes of students of SMAN 1 Sungai Apit and students' responses to the module. This research was conducted in three stages, namely problem analysis, development, and testing with purposive sampling technique. The discovery learning model has fulfilled the scientific principles, but the design is not complete according to the syntax of the discovery learning model in the planning stage and the implementation stage. Evaluation, which is used by observing student activeness and conducting tests to students, namely by assignment and practice. In addition to student participation, it takes the active role of subject teachers and support facilities from the school. Abstrak. Pendekatan metode pembelajaran biologi dengan materi biodiversitas yang menggali potensi alam seperti mengenal maskot flora dan fauna daerah dapat menjadi sebuah gagasan untuk membentuk karakter positif siswa salah satunya peduli lingkungan dan memiliki kebanggaan atas identitas daerah. Studi ini mengeksplorasi kelayakan dan efektivitas modul yang bertujuan memperkaya pendidikan biodiversitas melalui pengenalan maskot flora dan fauna daerah. Studi ini dilakukan di SMAN 1 Sungai Apit dengan mengikuti tiga tahap: analisis masalah, pengembangan, dan pengujian. Studi ini menemukan bahwa meskipun model discovery learning sesuai dengan prinsip-prinsip ilmiah, perlu penyempurnaan lebih lanjut dalam desain dan implementasinya. Modul menunjukkan potensi dalam meningkatkan keterlibatan siswa dan kesadaran lingkungan, tetapi membutuhkan peran aktif guru dan fasilitas sekolah yang memadai untuk efektivitas optimal.

Abstract

The plankton community structure is a collection of zooplankton and phytoplankton populations that interact with each other in a waters. This study aims to analyze the structure of the plankton community and the influence of environmental conditions (physico-chemical) on the structure of the plankton community in the ponds. The research sample was taken using a purposive sampling method, which represents three types of catfish ponds, namely, earthen ponds, tarpaulins, and biofloc. The results showed that in the three types of ponds studied, there were two species of zooplankton and 45 species of phytoplankton. Phytoplankton in soil ponds was dominated by Stigeoclonium subsecundum. Meanwhile, the zooplankton was dominated by Nebela collaris. Diversity (H') of zooplankton is in the low category with polluted water quality in the three ponds, while phytoplankton is in the high-low category. The equitability index (E) of zooplankton is in the stable category, while phytoplankton is in the depressed-stable category. The dominance index (D) of zooplankton belongs to the medium-low category, while phytoplankton belongs to the low category. As for the physico-chemical parameters of the waters, the three types of ponds have different effects from each parameter tested on the structure of the plankton community.

Abstract

This study aims to highlight and evaluate the issues at an in-depth level to provide different solutions that are expected to be a reflection for the government, especially the Ministry of Education and Culture, to be able to improve the implementation and monitoring of the Kampus Mengajar Program. A descriptive qualitative approach was used, and the data were collected from a focus group discussion with students of the English Education Study Program at Universitas Lancang Kuning, then the data was analyzed descriptively. The results highlight some problems in the implementation of the Kampus Merdeka Program. These included a lack of coordination and clear communication between stakeholders, which led to confusion among students and schools, uneven targeting of schools, inadequate support for the program, and credit conversion, resulting in frustration and challenges. Addressing these issues, the study recommended increased socialization of the program, transparency in credit equivalency, and more accurate school data collection. In conclusion, this research offers several solutions that are expected to reflect the Ministry of Education, Culture, Research and Technology (Kemendikbudristek) that the Kampus Mengajar Program faces various challenges in its implementation, which need to be addressed for the program to effectively meet its goal of improving education in the 3T areas.
