Abstract

This research aims to discuss the crucial role of analysing the National Education Report Card as an instrument of education quality management. The focus is on the importance of consistency in deciphering report card data to evaluate student, teacher and overall education policy performance. Through this approach, the article illustrates how appropriate analyses can provide an in-depth view of education trends, identify potential improvements, and support data-driven decision-making. The report also highlights the impact of consistency in research on the efficiency of the national education system, providing a basis for developing more effective strategies to improve learning quality sustainably.

Abstract

Salah satu aspek pemasaran yang harus diperhatikan dalam peningkatan arus penjualan gabah dari produsen awal sampai ke tangan pengempul yaitu efisiensi pemasaran. Penelitian ini bertujuan untuk mengetahui saluran pemasaran padi dan struktur pemasaran yang ada di Desa Demung Kecamatan Besuki Kabupaten Situbondo. Metode yang digunakan dalam penelitian ini menggunakan metode simple random sampling untuk petani, dimana jumlah sampel yang diambil sebanyak 40 orang. Sedangkan untuk lembaga pemasaran menggunakan metode snowball sampling. Berdasarkan hasil penelitian, bahwa saluran pemasaran yang ada di Desa Demung terdiri dari dua saluran pemasara, yaitu saluran I (Petani - Tengkulak – penggilingan – Distributor – Pedagang – Konsumen ) yang digunakan sebanyak 30 petani dan saluran II (Petani – Penggilingan – Distributor – Pedagang – Konsumen) yang digunakan sebanyak 10 petani. Struktur pasar padi yang ada di Desa Demung yaitu oligopsoni, dimana pangsa pasar sebesar 75,7% dengan Kr sebesar 0,75 dan IHH sebesar 0,61.

Abstract

The way to increase heat transfer is to use nanofluids and expand the heat transfer area. This research studied the thermal performance, convection heat change coefficient, and pressure drop in a double pipe heat exchanger experimentally in a vertically arranged helical microfin tube heat exchanger. Hot water flows on the side of the annulus. In contrast, nanofluid CuO/distilled water concentration of 0.05 vol% flows laminarly in the inner pipe of the microfin tube with cross-flow and parallel-flow arrangements. The result is convection heat transfer coefficient enhancement and thermal performance factor compared to the base fluid. Counter flow improves heat transfer better than parallel flow. This research contributes to the use of helical microfin and nanofluids to increase heat transfer in heat exchangers used in industrial processes.
