Abstract

Makroinvertebrata merupakan organisme tidak bertulang belakang yang memiliki ukuran kasat mata, memiliki habitat di darat, dalam  tanah, perairan meliputi air laut dan tawar. Kelompok makroinvertebrata di perairan bisa dijadikan bioindikator suatu perairan. Makroinvertebrata di perairan air tawar contohnya kelompok keong air tawar, serangga air, udang dan Clitellata seperti lintah. Penelitian dilakukan pada bulan Oktober 2023 sampai Januari 2024 menggunakan teknik purposive sampling. Pengambilan sampel menggunakan leaf litter bags, jaring seser, dan mengambil sedimen dasar perairan menggunakan ember. Pengukuran parameter lingkungan dilakukan meliputi pengukuran intensitas cahaya, suhu air, tingkat keasaman (pH), oksigen terlarut (DO), kedalaman lumpur, dan kedalaman air. Analisis data menggunakan indeks Shannon-Wiener, indeks Eveness dan indeks Simpson. Hasil identifikasi makroinvertebrata menunjukkan terdapat 16 spesies terdiri atas 13 famili dan 4 kelas. Indeks keanekaragaman makroinvertebrata di area kolam konservasi ex-situ kura-kura Siebenrockiella crassicollis Universitas Bengkulu secara umum tekanan ekologis berada pada kondisi tekanan rendah hingga sedang, dapat dilihat pada nilai H’ berkisar antara 0,981 sampai 1,577, indeks keseragaman berkisar antara 0,354 sampai 0,569 dan indeks dominansi berkisar antara 0,342 sampai 0,506. Kelimpahan, keanekaragaman, keseragaman dan dominansi makroinvertebrata dipengaruhi oleh parameter fisika kimia dan kondisi lingkungan.

Abstract

The Palak Siring Waterfall is a natural tourism object located in Kemumu Village, Armajaya District, North Bengkulu Regency were the area have variety of vegetation. This research aims to analyze the Terrestrial Fern Diversity in that area. The benefits of ferns in an ecosystem are as one of the pioneer organisms that open and start a new life in an ecosystem, food sources, and planting media. The method used is transect by forming (five) plots based on the slope of the land, consist of flat, sloping, rather steep, steep, and very steep areas. Plot size of 20 x 20 m placed along the transect line. Based on the survey was found 22 species with 13 types of family ferns in the Palak Siring Waterfall. The Diversity Index value of ferns (pteridophyta) belongs to the medium category. This certainly indicates that there is a fern that can adapt to the environment as well as other plants in area. Diversity of fern have the potential to be applied to junior high school science learning through several Basic competencies, materials, and forms of learning activities.

Abstract

This study aims to improve the quality of learning in Organic Chemistry 1. The specific objective of this study is to determine the difference in learning outcomes between students who use MOOCs (Massive Open Online Courses) and WhatsApp using the Project-Based Learning model. The type of research used is quasi-experimental research with a sample of third-semester students from Class A and Class B. This study uses two experimental classes, namely Class A using MOOCs and Class B using the WhatsApp application. The data analysis used is the average score, homogeneity test, normality test, and t-test. Based on the research results, there is a difference in learning outcomes between MOOCs and WhatsApp Group (WAG) applications with the same learning model treatment, namely the PjBL model, with a sig value (2-tailed) of 0.000, indicating p < 0.05. It can be concluded that there is a significant difference in the learning outcomes of the two experimental classes. Student responses to MOOCs and WAG applications are very good. Students stated that MOOCs and WAG applications are very practical, interesting, and easily accessible, especially for access to learning materials.

ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh model Problem based Learning (PBL) berbantuan Handout  terhadap hasil belajar peserta didik kelas VII di SMPN 15 Kota Bengkulu dalam materi pencemaran lingkungan.. Sampel penelitian diambil menggunakan teknik purposive sampling dengan berbagai pertimbangan maka dipilih kelas VII D dengan jumlah siswa sebanyak 24 siswa yang terdiri dari 11 siswa laki-laki dan 13 siswa perempuan. Jenis penelitian ini adalah Pre-Experimental Design tipe One-Group Pretest-Postest Design. Pengumpulan data hasil belajar siswa dilakukan dengan memberikan lembar soal berupa Pretest (tes awal) dan Postest (tes akhir) di setiap pertemuan. Uji hipotesis  dilakukan  menggunakan uji –t. Jika dari hasil  uji –t tersebut  terdapat perbedaan yang signifikan maka ditarik kesimpulan terdapat pengaruh penerapan model Problem Based Learning berbantuan handout terhadap hasil belajar siswa,  dan sebaliknya jika tidak terdapat perbedaan  yang signifikan maka tidak terdapat pengaruh. Hasil uji t diperoleh signifikasi hitung sebesar 0,00 > α = 0,05 sehingga Ho ditolak dan Ha diterima yang menyatakan bahwa terdapat perbedaan hasil belajar yang signifikan antara sebelum dan setelah siswa mengikuti pembelajaran Problem based Learning menggunakan handout. Berdasarkan hasil perhitungan N-gain score rerata sebesar 0,512 dalam kategori sedang. Berdasarkan hasil perhitungan effect size  diperoleh nilai sebesar 0,27 dalam kategori sedang. Dapat disimpulkan terdapat pengaruh penerapan model problem based learning menggunakan Handout Ilmu Pengetahuan Alam terhadap hasil belajar materi pencemaran lingkungan, dengan besar pengaruh pada kategori sedang. Kata kunci: Problem Based Learning, Handout, Pencemaran Lingkungan, Hasil Belajar ABSTRACT This study aims to determine the effect of the Problem-based Learning (PBL) model assisted by Handout on the learning outcomes of seventh grade students at Junior High School 15 Bengkulu City in environmental pollution material. The research sample was taken using purposive sampling technique with various considerations, class VII D was chosen with a total of 24 students consisting of 11 male students and 13 female students. This type of research is Pre-Experimental Design type One-Group Pretest-Postest Design. Data collection on student learning outcomes was carried out by giving question sheets in the form of Pretest (initial test) and Postest (final test) at each meeting. Hypothesis testing was carried out using the t-test. If from the results of the t-test there is a significant difference, it is concluded that there is an effect of applying the Problem Based Learning model assisted by handouts on student learning outcomes, and vice versa if there is no significant difference, there is no effect. The t-test results obtained a significance count of 0.00> α = 0.05 so that Ho is rejected and Ha is accepted which states that there is a significant difference in learning outcomes between before and after students take part in Problem-based Learning learning assisted by handouts. Based on the results of the calculation of the average N-gain score of 0.512 in the medium category. Based on the results of the calculation of effect size obtained a value of 0.27 in the medium category. It can be concluded that there is an effect of applying the problem-based learning model using the Natural Science Handout on the learning outcomes of environmental pollution material, with a large effect in the moderate category.
