Abstract

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.

Abstract

Malayan soft- shelled Turtle (Dogania subplana) is a species of freshwater softshell turtle that inhabits streams and swamps. This species is considered threatened with extinction and is listed in Appendix III of CITES and as Least Concern by the IUCN. This study aims to design an artificial habitat as a conservation effort and to identify the behavioral adaptations of Dogania subplana. The research method used an ecology-based design. The research subjects were five individuals of D. subplana, consisting of three females and two males. Data collection methods included field observation, literature review, and documentation. Research instruments involved environmental sensors to measure abiotic data. Data analysis was conducted both qualitatively and quantitatively. Qualitative data were analyzed descriptively through systematic and accurate reviews based on field findings and supported with photographic documentation. Quantitative data were analyzed using the average percentage of observed behaviors, presented in graphs, and supported by measured environmental abiotic data. The study results outline the stages of artificial habitat design for D. subplana, which include: location design, area division based on function, addition of supporting biota, fencing, and acclimatization. Observations revealed three behaviors feeding, basking, and aggression which were influenced by environmental temperatures from 26–31°C. D. subplana behaviors were observed only in aquatic areas with sandy and rocky substrates, indicating that such behaviors are strongly influenced by both terrestrial and aquatic environmental conditions. The study concludes that the artificial habitat at the Turtle Learning Center (TLC) of the University of Bengkulu, designed with three zones land, mud, and water effectively supports the natural adaptations and activities of D. subplana, as indicated by their feeding, basking, and aggressive behaviors.

Abstract

Lotus adalah tanaman air yang memiliki habitat alami di rawa atau tempat berlumpur. Pertumbuhan dan perkembangan lotus perlu dikaji lebih dalam untuk mempermudah proses budidaya. Budidaya lotus di bengkulu masih terbilang minim, meskipun di beberapa daerah sudah ada hanya dijadikan sebagai tanaman hias. Penelitian ini bertujuan untuk mengetahui pertumbuhan dan perkembangan lotus di kolam sains Universitas Bengkulu. Pengamatan dilakukan pada 4 stasiun penelitian dengan variasi ketinggian air dan lumpur yang berbeda. Parameter pertumbuhan lotus yang diamati adalah pertumbuhan biji (pertumbuhan tunas, jumlah tunas, jumlah daun, jumlah akar dan panjang akar), pertumbuhan bibit (jumlah daun, diameter daun, jumlah rimpang dan perbandingan pertumbuhan daun melayang dan daun koin), dan pemanenan (pertumbuhan bunga dan biji yang dihasilkan) dan dianalisis secara deskriptif kualitatif. Hasil penelitian menunjukkan bahwa pertumbuhan bibit lebih maksimal dari biji yang memiliki ciri dengan bentuk membulat sempurna, tidak kisut dan tidak berjamur. Lokasi terbaik untuk pertumbuhan dan perkembangan lotus yaitu pada plot 2 dilihat dari laju pertumbuhan yang lebih cepat dibandingkan plot 1, plot 3 dan plot 4 dengan Parameter pertumbuhan pada plot 2 memiliki rata-rata diameter daun 66,3 mm, jumlah daun 5 helai, diameter tangkai daun 2 mm, dan jumlah rimpang 5 ruas. Jumlah biji yang dihasilkan memiliki rata-rata 28 terdiri dari 19 biji fertil dan 9 biji infertil. Pertumbuhan dan perkembangan tanaman lotus di kolam sains lebih maksimal dengan ciri lokasi yaitu kedalaman lumpur 62 cm dan kedalaman air 21 cm. Bunga lotus lebih banyak menghasilkan biji fertil dibandingkan dengan biji infertil yang menunjukkan tingkat keberhasilan penyerbukan tinggi.
