The structure and diversity of understory herb vegetation were studied at Tropical Mountain Forest of Mount Bawakaraeng, South Sulawesi. The study was conducted at two areas. The first area was natural forest (NF) (Site 1). The second area (Site 2) was dominated by Pteridium aquilinum (L.) Kuhn ferns and Lantana camara shrubs (NP). The value of similarity index between the two sides was 22,15. The mean values of diversity parameters at Site 2 relatively higher compared to those in Site 1. The Dominance Diversity Curve for Site 2 shows curve that longer than that of Site 1. There are 12 species that are found at both sites. At Site 1, the highest mean value of Species Richness (S) and Shannon Wiener Diversity Index (H’) are found in Rather Steep Slope (RSS) and the lowest are in Gentle Slope (GS). In the Site 2 area, the highest mean value of S, H’, Simpson’s Diversity Index (1-D) and Pielou’s Evenness Index (E) are found in Flat Slope (FS) and the lowest is in RSS, whilst the highest value of Simpson’s Dominance Index (D) is in RSS and followed in FS and finally in GS. At Site 1, species with highest important value index (IVI) are varying. The most dominant species at Site 2 is Isachne globosa. The Asteraceae family is the family that has species with highest IVI at Site 1. At Site 2, Poaceae family is the plan family that has the most species with the highest IVI at all slope level.

Games that improve the ability of elementary school students to learn abstract things is needed more now than ever before. Learning media is important in presenting the subject of learning. The purpose of this study was to develop a mathematical learning media design on plane subject using the Android operating system applicable on mobile phones. The methodology used was Research and Development (RnD) with ADDIE approach. The research included three stages 1) Analysis of the needs and availability of mathematics learning media needed by elementary school students. 2). Designing the appearance of puzzle and games subject suitable for elementary school students. 3) Development of mathematics learning media using android-based puzzle games.

Penelitian ini bertujuan untuk menganalisis pengaruh Capital Adequacy Ratio (CAR), Loan to Deposit Ratio (LDR), Biaya Operasional dan Pendapatan Operasional (BOPO) terhadap Return on Asset (ROA) pada Perbankan yang Terdaftar di Bursa Efek Indonesia. Jenis data yang digunakan adalah data sekunder yang berasal dari publikasi laporan keuangan Perusahaan Perbankan yang terdaftar di Bursa Efek Indonesia Periode Tahun 2017 – 2019. Teknik analisis data yang digunakan adalah analisis regresi linear berganda dengan bantuan Program SPSS versi 25. Hasil penelitian menunjukkan bahwa variabel Capital Adequacy Ratio (CAR) berpengaruh positif dan signifikan terhadap Return on Asset (ROA), variabel Loan to Deposit Ratio (LDR) berpengaruh negatif dan tidak signifikan terhadap Return on Asset (ROA), dan Biaya Operasional dan Pendapatan Operasional (BOPO) berpengaruh negatif dan signifikan terhadap Return on Asset (ROA).

Penelitian ini merupakan penelitian eksperimen semu (quasy experimental) yang bertujuan untuk mengetahui pengaruh penggunaan media power point dan animasi terhadap hasil belajar biologi siswa Kelas XI IPA SMA Negeri 1 Makassar. Hipotesis penelitian ini adalah  ada pengaruh penggunaan media power point terhadap hasil belajar biologi siswa. Sampel penelitian ini adalah siswa SMA Negeri 1 Makassar kelas XI IPA2sebagai kelas eksperimen dengan jumlah siswa 32 orang dan kelas XI IPA3 sebagai kelas kontrol dengan jumlah siswa 32 orang. Penelitian ini dilaksanakan selama 5 kali pertemuan. Pengukuran hasil belajar dilakukan dengan memberikan tes hasil belajar dalam bentuk pilihan ganda. Pengambilan data dilakukan dengan mengevaluasi hasil belajar, melalui tes tertulis yang meliputi Pretes (tes hasil belajar kognitif awal siswa) dan postest (tes hasil belajar kognitif akhir siswa) Data yang terkumpul dianalisis secara statistik deskriptif dengan menggunakan pedoman pengkategorian hasil belajar menurut Arikunto dan uji hipotesis secara inferensial dengan menggunakan analisis kovariansi (Anakova) dengan taraf signifikan 5%. Hasil penelitian menunjukkan bahwa media pembelajaran diperoleh nilai p lebih kecil dari alpha 0,05 (p < 0,05) dengan sig. 0,010. Dengan demikian dapat disimpulkan bahwa media pembelajaran berpengaruh terhadap hasil belajar biologi siswa.

This study is a development research, which uses ADDIE development model. The study was conducted in the even semester of the academic year 2019/2020. The authentic assessment instruments developed consist of cognitive and psychomotor assessment instruments for measuring the students’ science literacy skills in 10th grade on Environmental Change material. Indicators of scientific literacy refer to indicators developed by Gormally (2012). Measurement aspect were the validity by the expert appraisal and empirical validity test, difficulty level and practicability of instrument. The results of study showed the authentic assessment instruments that had been developed were proper to use with validity value 4.43. Empirical validity data for multiple choice were analysed using point biserial correlation. Result showed 76% in valid category with reliability value 0,82. For essay and psychomotor assessment showed 100% in valid category. The reliability value for essay is in the reliable category with value 0,62. Psychomotor assessment with reliability value 0,89. Difficulty index of assessment instrument in cognitive domain for multiple choice were 24 % in difficult level, 44 % in moderate level and 32 % in easy level, meanwhile for essay 40 % difficulty index in moderate level and 60 % in easy level. Result of data analysis for and practicality of authentic assessment instruments based on scientific literacy were in practically category.
