Pandanduri Dam waters has an essential function for the community made the activities of the surrounding community inseparable from the Pandanduri Dam that made potentially quality change of the Pandanduri Dam waters. Good water quality is an important requirement for humans that made water quality research is essential to be done. Human activities will affect environmental factors such as biological parameters, especially phytoplankton, which are indicators of water quality. The aim of this study was to analyzed water quality of Pandanduri Dam through study of phytoplankton community and diversity. Sample sites were determined based on haphazard sampling method and phytoplankton data were analyzed based on the shannon-weiner diversity index. The results showed that the phytoplankton community identified in Pandanduri Dam consisted of 5 classes, 13 orders, and 31 species with  species diversity index of 2,659. Based on fitoplankton diversity index value the water of  Pandanduri Dam was in lightly polluted category. It is suggested to more detailed studies should be undertaken especially on species that produce toxins over a longer time scale.

Berdasrkan hasil analisis disimpulkan bahwa kegiatan pelatihan operasionalisasi program IBM SPSS 21 dan meningkatkan pemahaman dan keaktifan mahasiswa dalam menerapkan penggunaan program SPSS sebagai sarana mengolah data penelitian.

Geographical conditions affect human physical and physiological conditions, one of the examples is the height of residence that can make the respiratory system different among population groups. This study aims to compare the respiratory system between highlanders and lowlanders in terms of hemoglobin levels, blood oxygen saturation, and breaths frequency. The research model used was a comparative study with a purposive sampling method based on: age criteria with a range of 16-19 years, a minimum of 6 months stayed at the research location, and there is no recorded respiratory system disease. Data analysis used was independent t-test with Shapiro-Wilk prerequisite test for normality and one-way ANOVA for homogeneity, then Mann-Whitney test for follow-up non-parametric test. The results showed that the highlanders generally have oxygen saturation and hemoglobin levels with an average value of 98.81% and 14.69g/dL higher than those in the lowlands with a value of 97.86% and 13.14g/dL. On the other hand, the average value of breath frequency of highlanders is 17.38/minute which tends to be lower than that of lowlanders with 24.17/minute. The prerequisite test showed highlanders oxygen saturation data that were not normally distributed with a significance value of 0.003, then oxygen saturation data and breath frequency were not homogeneous with a significance value of 0.000 and 0.003 respectively. The comparative test showed a significance value of 0.002 for hemoglobin through independent t-test, then obtained asymptomatic significance values ​​of 0.004 and 0.000 for oxygen saturation and breaths frequency through the Mann-Whitney test. Based on the significance value obtained, it can be stated that there are significant differences in hemoglobin levels, oxygen saturation, and breaths frequency per minute between highland and lowland residents. It is recommended to conduct further research on lung capacity and chest cavity index to provide a more holistic explanation of the differences in the respiratory system between highland and lowland residents.

Literasi sains dan keterampilan berargumentasi ilmiah sangat krusial untuk diintegrasikan ke dalam pembelajaran di sekolah. Next Generation Science Standard dan game discovery dipandang kompatibel untuk melatih literasi sains dan keterampilan berargumentasi ilmiah dalam pembelajaran. Penelitian ini bertujuan untuk: 1) menganalisis tingkat kebutuhan pengembangan bahan ajar berbasis NGSS terintegrasi game discovery (BANDI); 2) merumuskan kerangka dasar BANDI; 3) menganalisis kelayakan BANDI. Jenis penelitian ini adalah research and development (R&D) dengan menggunakan model ADDIE. Subjek penelitian ini adalah kelas X IPA SMAN 01 Labuhan Haji. Teknik pengumpulan data melalui pengamatan langsung dan kuesioner. Analisis data menggunakan Content validity index (CVI), Percentage of agreement (PA), Flesch Kincaid grade level (FKGL), dan persentase nilai tanggapan. Hasil penelitian menunjukkan bahwa: 1) tingkat kebutuhan bandi berada pada kategori sangat dibutuhkan baik melalui respon siswa maupun guru, 2) Kerangka dasar BANDI terdiri atas 4 item (umum, basis, kompetensi, dan teknologi); 3) BANDI terkonfirmasi layak dikarenakan memenuhi aspek validitas, reliabilitas, keterbacaan, dan ketercapaian. Pemenuhan aspek kelayakan terlihat melalui hasil analisis data validitas BANDI melalui CVI dengan nilai rata-rata sebesar 0,96 dengan kategori valid, reliabilitas dianalisis melalui PA dengan nilai rata-rata sebesar 89,80% dengan kategori reliabel, keterbacaan sesuai dengan usia pengguna yaitu 15-16 tahun dengan nilai FKGL 10,69, serta keterterapan terkonfirmasi melalui uji kelompok kecil dengan nilai respon 89,39% untuk aspek kemudahan dan 84,52% untuk keefektifan penggunaan. Berdasarkan hasil yang diperoleh, maka dapat disimpulkan bahwa BANDI layak untuk selanjutnya digunakan dalam pembelajaran untuk memfasilitasi literasi sains dan keterapilan berargumentasi ilmiah di sekolah.
