Motivasi Berafiliasi merupakan hal yang paling efektif dalam keaktifan pembelajaran. Penelitian ini bertujuan untuk mengetahui pengaruh motivasi berafiliasi terhadap keaktifan dalam pembelajaran matematika. Metode yang digunakan ex post facto sering disebut dengan after the fact artinya penelitian yang dilakukan untuk mengetahui penyebab-penyebab terhadap peristiwa yang sudah terjadi. Populasi pada penelitian ini semua siswa kelas V SD Inpres Perumnas Antang Kota Makassar yang terdiri 92 siswa, dengan teknik Simple Random Sampling sampel yakni 32 siswa. Hasil penelitian menggunakkan analisis statistik deskriptif, nilai rata-rata motivasi berafiliasi adalah 43,25 berada pada kategori baik dan nilai ratarata keaktifan pembelajaran matematika 40,88 berada pada kategori baik dan analisis statistik inferensial, hasil uji normalitas motivasi berafiliasi 0,221 dan keaktifan 0,237 lebih dari 0,05 (berdistribusi normal), hasil uji homogenitas adalah 0,351 lebih dari 0,05 (homogen), hasil uji linearitas adalah 0,213 lebih dari 0,05 dengan demikian terdapat hubungan yang linear motivasi berafiliasi terhadap keaktifan dan hasil uji hipotesis menunjukkan nilai sig 0,001, dengan kriteria Sig (0,001) α (0,05) sehingga dapat disimpulkan bahwa terdapat pengaruh motivasi berafiliasi terhadap keaktifan pembelajaran matematika kelas V SD Inpres Perumnas Antang Kota Makassar

Seiring berkembangnya dunia bisnis seperti sekarang ini, e-commerce menjadi salah satu faktor dalam meningkatkan dan memenangkan persaingan dalam hal bisnis dan penjualan produk. Bisnis yang akan dikembangkan sebaiknya dilakukan analisa secara mendalam terkait kelebihan dan kekurangan bisnis tersebut. Studi kasus penelitian pada Toko H5 yang bergerak dibidang fashion. Sistem pada Toko H5 yang secara keseluruhan masih konvensional menjadi permasalahan pertama yang ditemukan. Masalah lain datang selama masa pandemi, omset yang menurun cukup signifikan diperikarakan mencapai 50% dibanding sebelum masa pandemi. Business Model Canvas (BMC) adalah suatu model strategi bisnis yang menggunakan sembilan blok penting. BMC digunakan oleh perusahaan dan startup untuk mendapatkan wawasan tentang analisis model bisnis mereka. Penelitian ini menggunakan analisis proses bisnis yang dilakukan dengan metode BMC untuk menghasilkan e-commerce sehingga model bisnis yang ada kemudian dapat diubah menjadi model bisnis berbasis e-commerce di web. Tujuannya yakni mengoptimalkan kinerja terutama peningkatan sektor penjualan produk sehingga dapat meningkatkan omset pada Toko H5, karyawan menjadi mudah melakukan pendataan stok dan laporan penjualan, serta membantu pelanggan untuk berbelanja secara online melalui E-Commerce.

The inflation and interest rates in Indonesia have a significant impact on the country's economic development. Indonesian inflation and interest rates data are multivariate time series data that show activity over a certain period of time. Vector Autoregressive Integrated Moving Average (VARIMA) is a method for analyzing multivariate time series data. This method is a simultaneous equation modeling that has several endogenous variables simultaneously. This study aimed to model the inflation and interest rates data, from January 2009 to December 2016 and predict inflation and interest rates by using VARIMA method. The model obtained was the VARIMA(0,2,2) model, with estimated parameters using the maximum likelihood method. The choice of the VARIMA(0,2,2) model was based on the smallest AIC value of -4,2891, with a MAPE value for the inflation and interest rates forecasting were 6,04% and 1,84%, respectively, which indicates a very good forecast results.

The role of BBM is very important in people's lives. Fuel is a basic need for rural and urban communities, both as household needs and as business needs. The existence of kerosene in Jayapura is quite evenly distributed. From the results of survey conducted by the OFFICE OF INDUSTRY, COOPERATIVE TRADE AND SMEs that every year the use of LPG as fuel for cooking is still very low, while the use of kerosene from year to year is widely used by local community, it causes more kerosene bussiness but people have difficulty getting information about the location to get the kerosene, therefore we need a system that can help find the location, namely geographic information system that can provide information about fuel oil base points. This system is in symbols form for making the system using QGIS with the PIECES analysis method, the design using Unified Modeling Language (UML) method and the development method using waterfall method. This research produces a system that can be expected to make it easier for the public to know the distribution of kerosene in Jayapura

Remaja adalah suatu tahap transisi antara masa kanak-kanak kemasa dewasa. Remaja akan mengalami masa pubertas, salah satu tanda pubertas remaja yaitu menstruasi. Obesitas adalah penimbunan jaringan lemak tubuh secara berlebihan, sehingga meningkatkan kadar prostaglandin dalam tubuh dan memicu terjadinya dismenore. Tujuan penelitian ini, mengetahui hubungan kejadian obesitas dengan tingkat dismenore pada remaja putri di SMAN 20 Bone. Desain penelitian yang di gunakan adalah obeservasional analitik dengan pendekatan Cross sectional study. Dilaksanakan di SMAN 20 Bone pada bulan Agustus 2019. Populasi penelitian ini, semua siswi kelas X dan XI jurusan IPA dan IPS yaitu sebanyak 115 siswi. Adapun penentuan perkiraan jumlah sampel yang akan diambil digunakan rumus slovin dengan teknik Stratified Sampling yaitu sebanyak 90 sisiwi. Hasil penelitian menunjukkan bahwa siswi yang obesitas dan mengalami tingkat dismenore (tidak nyeri, ringan, sedang, berat dan sangat berat) sebanyak 40 sisiwi. Uji hubungan dilakukan dengan menggunakan uji statistik Chi-Square, dengan tingkat kemaknaan, nilai ρ=value 0,003 (<0,05). Kesimpulan dari penelitian ini, menunjukkan bahwa ada hubungan kejadian obesitas dengan tingkat dismenore pada remaja putri di SMAN 20 Bone. Teenagers are a transitional stage between childhood and adulthood. Teenagers will experience puberty, one sign of adolescent puberty is menstruation. Obesity is excessive accumulation of body fat tissue, thereby increasing prostaglandin levels in the body and triggering dysmenorrhea. The purpose of this study was to determine the relationship of the incidence of obesity with the level of dysmenorrhea in young women at SMAN 20 Bone. The research design used was observational analytic with cross sectional study approach. Conducted at 20 Bone High School in August 2019. The population of this study, all students of class X and XI majoring in Natural Sciences and Social Sciences as many as 115 students. The determination of the estimated number of samples to be taken used the Slovin formula with the Stratified Sampling technique of 90 students. The results showed that students who were obese and experienced levels of dysmenorrhea (painless, mild, moderate, severe and very severe) were 40 students. The relationship test was performed using the Chi-Square statistical test, with significance level, the value of ρ = value 0.003 (<0.05). The conclusions of this study, show that there is a relationship between the incidence of obesity with the level of dysmenorrhea in young women at SMAN 20 Bone.

This research aims to develop worksheets through Creative Problem Solving (CPS) model to improve students' creative thinking. The implementation of the research conducted by Research & Development (R & D), with a model of Four-D development. This model consists of 4 stages of development: Define, Design, Develop and Disseminate, with the development of learning mathematics of worksheets for the material fractions through Creative Problem Solving (CPS) model to improve creative thinking the fifth-grade students of SD Tunas Bangsa Makassar. The instrument used in this research was the sheet validity test, sheet test the practicalities, and the post-test (students thinking creatively). Based on the validity test results, worksheets through the model of creative problem solving (CPS) with an average value of 4,01 and valid category. While the test results in the practicalities when the trial was limited worksheets with model creative problem solving (CPS) belongs to the category was very practical, with the percentage of 82,43%. Based on the post-test results, students' creative thinking was the category of creative with a percentage of 81,68%. Finally, it can be concluded that worksheets through a model of creative problem solving (CPS) to improve students' creative thinking that developed were valid, practical, and useful. So it can be applied in class V of mathematics subject.
