Abstract

This study aimed to inventory the dragonfly species inhabiting the Sendang Gile Waterfall area, evaluate their diversity, and develop the findings into a local biodiversity-based biology learning resource for senior high school students. A descriptive exploratory approach was employed using a sweep net sampling method along three observation transects. Species diversity was analyzed using the Shannon–Wiener diversity index (H′), evenness index (E), and dominance index (C). The research findings were subsequently developed into a biology booklet and evaluated through expert validation involving material and media specialists. A total of 364 dragonfly individuals representing 12 species from five families were recorded. Euphaea lara lombokensis was the most abundant species, accounting for 119 individuals. The overall Shannon–Wiener diversity index (H′ = 1.81) indicated a moderate level of species diversity, accompanied by a relatively balanced species distribution and low dominance. The developed booklet obtained an average validation score of 90.09%, indicating that it was highly valid and suitable for educational use. These findings demonstrate that the Sendang Gile Waterfall area supports a moderately diverse dragonfly community and that the developed booklet can serve as an effective local biodiversity-based learning resource for biology education in senior high schools.

Abstract

Pembelajaran di sekolah dasar perlu memberikan pengalaman belajar yang bermakna sehingga siswa dapat membangun pengetahuan secara aktif dan memecahkan masalah yang berkaitan dengan kehidupan sehari-hari. Problem Based Learning (PBL) menempatkan masalah sebagai pusat pembelajaran dan siswa sebagai pembelajar aktif melalui kegiatan penyelidikan, kolaborasi, dan penyusunan solusi. Penelitian ini bertujuan untuk mengetahui pengaruh model Problem Based Learning terhadap hasil belajar IPAS siswa kelas V SD Negeri Kerato Sumbawa. Penelitian menggunakan pendekatan kuantitatif dengan metode quasi experiment dan desain nonequivalent control group. Populasi penelitian berjumlah 40 siswa, dengan kelas V-A sebanyak 20 siswa sebagai kelompok eksperimen dan kelas V-B sebanyak 20 siswa sebagai kelompok kontrol. Data dikumpulkan menggunakan tes hasil belajar berbentuk pilihan ganda dan lembar observasi keterlaksanaan PBL. Instrumen diuji validitas dan reliabilitasnya; dari 30 butir yang diuji, 25 butir dinyatakan valid dan koefisien reliabilitas sebesar 0,952. Analisis data meliputi statistik deskriptif, uji normalitas Shapiro–Wilk, uji homogenitas Levene, uji Mann–Whitney, dan N-Gain. Hasil uji Mann–Whitney menunjukkan nilai Asymp. Sig. (2-tailed) sebesar 0,035 (<0,05). Rata-rata posttest kelas eksperimen sebesar 79,50, sedangkan kelas kontrol sebesar 67,00. Nilai N-Gain kelas eksperimen sebesar 0,683 dan kelas kontrol sebesar 0,406, keduanya berada pada kategori sedang. Keterlaksanaan PBL meningkat dari 70% pada pertemuan pertama menjadi 100% pada pertemuan ketiga dengan rata-rata 83,33%. Temuan menunjukkan adanya perbedaan hasil belajar yang signifikan secara statistik antara kedua kelompok, dengan peningkatan yang lebih besar pada kelompok eksperimen. Temuan perlu dipahami dengan mempertimbangkan keterbatasan desain quasi-eksperimen, durasi perlakuan tiga pertemuan, dan sampel yang berasal dari satu sekolah.

Abstract

This study aimed to analyze the effectiveness of ethanol extracts of basil leaves (Ocimum basilicum L.) and sweet flag rhizomes (Acorus calamus L.) as attractants and to evaluate the effect of extract concentration on fruit fly catches (Bactrocera spp.). The study was conducted in a crystal guava plantation in the Jempong Baru area of Mataram from June to August 2026. Fruit fly catches were observed using attractant traps containing ethanol extracts at concentrations of 0%, 5%, 15%, 30%, 45%, and 60%, with three replications for each treatment. The data were analyzed using a Generalized Linear Model (GLM) with a Poisson distribution, Followed by Benferroni-adjusted pairwise comparisons. A total of 296 fruit fly individuals belonging to Bactrocera dorsalis, Bactrocera umbrosa, and Bactrocera carambolae were collected. Fruit fly catches differed significantly between the two plant extracts and concentrations (p < 0.001). Basil leaf ethanol extract attracted more fruit flies than sweet flag rhizome ethanol extract, with estimated mean catches of 12.4 and 3,6 individuals, respectively. Mean fruit fly catches tended to increase with increasing extract concentration, with the highest mean catch observed at 60%. However, the 45% and 60% concentrations were not significantly different in the reported pairwise comparison. Thus, the 60% concentration produced the highest observed mean catch, but cannot be stated as an optimal concentration based solely on the present statistical comparison.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran kooperatif tipe Think Pair Share berbantuan Index Card Match terhadap kemampuan berpikir kritis siswa kelas IV SDN 3 Paok Motong. Penelitian ini menggunakan pendekatan kuantitatif dengan metode Quasi Experimental Design (eksperimen semu) dengan desain Nonequivalent Control Group Design. Penelitian dilaksanakan di SDN 3 Paok Motong pada semester genap Tahun Ajaran 2025/2026, yaitu pada bulan Mei–Juni 2026. Populasi penelitian adalah seluruh siswa kelas IV SDN 3 Paok Motong berjumlah 56 siswa. Teknik pengambilan sampel menggunakan Sampling jenuh, sehingga seluruh populasi dijadikan sampel penelitian yang terdiri dari dua kelas yaitu kelas IV A berjumlah 28 siswa ditetapkan sebagai kelas eksperimen dan kelas IV B berjumlah 28 siswa ditetapkan sebagai kelas kontrol. Teknik pengumpulan data menggunakan observasi, tes, dan dokumentasi. Data dianalisis menggunakan uji normalitas, uji homogenitas, dan uji hipotesis dengan bantuan aplikasi SPSS Statistics 25. Hasil uji hipotesis menggunakan Independent Sample t Test diperoleh nilai signifikansi sebesar 0,000, nilai signifikansi tersebut lebih kecil daripada taraf signifikansi 0,05 (0,000 < 0,05), artinya H0 ditolak dan Ha diterima. Dengan demikian, dapat disimpulkan bahwa ada pengaruh model pembelajaran kooperatif tipe Think Pair Share berbantuan Index Card Match terhadap kemampuan berpikir kritis siswa kelas IV SDN 3 Paok Motong.
