Where things will be involved are learning difficulties. Learning difficulties that are often carried out by children or students in the teaching and learning process. Teachers who have given the same lessons and the same method to students in one class but still have students who cannot absorb the lessons well even though they have the same perfect ones if they are seen with ordinary eyes. This is what found learning difficulties to exist. Where learning difficulties and student development will produce obstacles in information. Learning difficulties are internal and external factors. In this case, learning difficulties can be done because students relate to the psyche of students or with different learning with learning difficulties due to physical factors or physical disabilities.

Abstract

Hematoxylin-eosin staining is a crucial technique used in histopathology to differentiate tissue components. One of the steps in this staining is changing the color of the nucleus, which was previously reddish due to the acid solution, to bluish; this step is known as blueing. The bluing agent, lithium carbonate, is commonly used in laboratories but has side effects and low availability. Sodium bicarbonate, also known as baking soda, can be used as an alternative due to its optimal pH, lower toxicity, and availability. This study aims to find out whether baking soda is as effective as lithium carbonate when used as a blueing agent for hematoxylin-eosin staining. The study design used was a true experimental post-test only control group design with a sample size of 32 preparations. Results of preparations using baking soda microscopically had good color uniformity, the nucleus was visible, the cytoplasm was clear, so the boundaries between cells were visible, and no cell lysis was found. In percentage terms, 14 preparations received a score of two (87.5%), two preparations received a score of three (12.5%), followed by a P value of 0.051 after carrying out the Fisher's exact test in bivariate analysis. Based on the results, baking soda is as effective as lithium carbonate, so it can be used as an alternative to bluing agent of hematoxylin-eosin staining.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh harga minyak dunia dan harga emas dunia terhadap pergerakan Indeks Saham Syariah Indonesia (ISSI). Penelitian menggunakan pendekatan kuantitatif eksplanatori dengan data time series bulanan periode 2015–2024 yang dianalisis menggunakan regresi linear berganda melalui aplikasi SPSS 27, setelah terlebih dahulu dilakukan uji asumsi klasik untuk memenuhi kriteria Best Linear Unbiased Estimator (BLUE). Hasil penelitian menunjukkan bahwa harga minyak dunia dan harga emas dunia berpengaruh positif dan signifikan terhadap ISSI, baik secara parsial maupun simultan. Harga minyak dunia memiliki kontribusi pengaruh yang lebih dominan dibandingkan harga emas dunia, sementara nilai koefisien determinasi menunjukkan bahwa sebesar 65,3% variasi ISSI dapat dijelaskan oleh kedua variabel tersebut. Implikasi penelitian ini menegaskan pentingnya dinamika harga komoditas global sebagai faktor eksternal yang perlu diperhatikan oleh investor dan pembuat kebijakan dalam merespons perkembangan pasar modal syariah di Indonesia.
