Abstract

Geographically Weighted Logistic Regression (GWLR) model is a regression model developed from logistic regression which is applied to spatial data. The aims of research is a GWLR model determination on dichotomous data of community welfare status based on the Human Development Index (HDI) and to find the factors influencing the probability of high welfare status of each Regency/City on Kalimantan Island in 2017. Parameters estimation of the GWLR model was done at each observation location using a weighted Maximum Likelihood Estimation (MLE) method and maximum likelihood estimator was obtained by Newton Raphson iterative method. Spatial weighting on parameter estimation was determined using Adaptive Gaussian weighting function and optimum bandwidth was determined using Generalized Cross-Validation (GCV) criterion. Based on the result of GWLR parameter testing, it was concluded that the factors influencing the probability of high welfare status of Regency/City on Kalimantan Island in 2017 were school enrollment rates (senior high school), the number of health workers, real per capita income and the open unemployment rate.

Abstract: Lack of practical activities in schools can result in a decrease in the creativity of students. worksheets based on the discovery learning model in them trigger students to think creatively and critically. The sampling technique is cluster random sampling. The purpose of this study is to look at the improvement of skills competencies which are assisted by student worksheets based on the discovery learning model. The data analysis technique is testing hypotheses where there is a difference which means the use of this student worksheet. Hypothesis testing conditions are to carry out normality tests for skill scores from both sample classes and homogeneity tests to see the distribution of values from two sample classes that have homogeneous data. after treatment is obtained, the average value of the skills of the experimental class is 78.62 and for the control class is 70.10.Abstrak: Kurangnya kegiatan praktikum di sekolah dapat mengakibatkan penurunan kreativitas siswa. lembar kerja berbasis model discovery learning di dalamnya memicu siswa untuk berpikir kreatif dan kritis. Teknik pengambilan sampel adalah cluster random sampling. Tujuan dari penelitian ini adalah untuk melihat peningkatan kompetensi keterampilan yang dibantu oleh lembar kerja siswa berdasarkan pada model pembelajaran penemuan. Teknik analisis data menguji hipotesis di mana ada perbedaan yang berarti penggunaan lembar kerja siswa ini. syarat pengujian hipotesis adalah untuk melakukan tes normalitas untuk skor keterampilan dari kedua kelas sampel dan tes homogenitas untuk melihat distribusi nilai dari dua kelas sampel yang memiliki data homogen. setelah perawatan diperoleh, nilai rata-rata keterampilan dari kelas eksperimen adalah 78,62 dan untuk kelas kontrol adalah 70,10.

Abstract

Penelitian ini menggunakan pendekatan kuantitatif melalui metode survei yang dilakukan dengan menyebarkan kuesioner kepada 120 mahasiswa yang telah diseleksi berdasarkan kriteria tertentu. Data yang dikumpulkan dianalisis dengan regresi linier berganda menggunakan software SPSS versi 27. Hasil analisis menunjukkan bahwa literasi keuangan memiliki pengaruh yang positif dan signifikan terhadap kemampuan pengelolaan keuangan mahasiswa, dengan koefisien regresi sebesar 0,360 dan nilai signifikansi 0,02 (di bawah 0,05). Selain itu, penggunaan teknologi finansial juga menunjukkan pengaruh positif dan signifikan, dengan koefisien regresi sebesar 0,623 dan nilai signifikansi 0,00 (jauh di bawah 0,05).Dari hasil tersebut dapat disimpulkan bahwa peningkatan literasi keuangan dan pemanfaatan fintech secara optimal dapat menjadi strategi yang efektif untuk memperbaiki perilaku pengelolaan keuangan mahasiswa.

Abstract

Discovery of black turmeric's anti-radical, anti-inflammatory properties and ability to inhibit the growth of tumor cells. This study aimed to evaluate the cardioprotective effects and identity the effect of black turmeric (Curcuma caesia Roxb) ethanol extract in preventing cardiac damage in mice induced by doxorubicin. The experimental design employed is a pre-post test control group design. The study used male Wistar rats weighing between 150-200 grams, divided into 6 groups, with each group consisting of 4 rats. The first group, serving as the normal group, was only provided with food and water. The second group received Na-CMC as a negative control, while the third group was given Vitamin E as a positive control. The fourth, fifth, and sixth groups were administered suspensions of black turmeric extract at doses of 100, 300, and 500 mg/kg BW, respectively. The rats were induced with doxorubicin at a dose of 5 mg/kg BW once a week for 3weeks. On the final day of treatment, the rats were fasted for 18 hours, anesthetized, and blood samples were taken for analysis. The rats were also secured on a surgical board. Following induction, CKMB and LDH levels were measured again, and histopathological observations were conducted. The results showed CKMB levels indicated significant differences between groups with p<0,05 (0,025), while LDH levels did not show significant differences with p-value>0,05 (0,225). Histopathological examination of the heart revealed improvements in function and structure in the group IV.
