“…At present, there were three types of rural industrial integration models in China: the intra-agricultural industrial restructuring and integration model, the inter-agricultural industrial cross-fusion model and the advanced technology to agriculture penetration-type integration model (Layuk et al, 2021;Polcyn, 2021;Suryasa et al, 2021). The intra-agricultural industry restructuring and integration model was developed to integrate the various subindustries within the agricultural industry, such as planting, farming and aquaculture, with each other (Darmayanti et al, 2020;Liu et al, 2022;Ratini et al, 2020;Xie & Huang, 2021). By establishing organic links between upstream and downstream, it effectively integrated various resources and promoted the integrated development of various sub-industries within the agricultural industry to protect the environment, save resources and promote farmers' income (McInnis & Merajver, 2011).…”

Industrial integration provides an important tool to promote the revitalization of rural industries and is an effective way to promote sustainable income growth for farmers and to build a well-off society. The main implementer of rural industrial integration are individual farmers. The fundamental state of life of the farm households determines the implement ability of industrial farming cooperation. The development of rural industries has played an irreplaceable role in the process of poverty eradication in China. Promoting the integration of the three rural industries can play an important role in consolidating the fight against poverty and bridging the stage of rural revitalization to continuously play a role in the development of rural industries and lay the foundation for the smooth implementation of rural revitalization. Whereas human capital was one of the important perspectives in studying the integration of three rural industries, the relationship between human capital in education and the integration of three rural industries was empirically analyzed based on data from the China Household Tracking Survey (CFPS). With the help of a Random Forest model algorithm, the importance of key elements affecting the integration of rural industries was measured and ranked.

“…Dalam pengoperasian pesawat sinar-X, control panel digunakan sebagai pengatur parameter. Sistem sinar-X standar memiliki tiga prinsip pengendalian, yaitu tegangan (kV), arus tabung (mA), dan waktu eksposi (s) [8]. Transformator adalah alat elektromagnetik yang dapat mengubah tegangan arus bolak-balik dan menaikkan atau menurunkan tegangan.…”

Abstrak – Telah dilakukan penelitian untuk mengetahui pengaruh luas bidang penyinaran dan delay time processing terhadap exposure index (EI) dan deviation index (DI) computer radiografi (CR). Alat bantu yang digunakan berupa phantom skull, imaging plate, grid, dan CR. Faktor eksposi yang digunakan diatur konstan. Untuk mengetahui besar nilai EI dilakukan ekspose dengan variasi luas bidang penyinaran berikut, 25 cm x 25 cm, 25 cm x 28 cm, 28 cm x 30 cm, 30 cm x 36 cm dan 30 cm x 43 cm. Kemudian dilakukan ekspose dengan menggunakan luas bidang penyinaran konstan yaitu 25 cm x 25 cm, namun dilakukan variasi delay time processing sebagai berikut, 5, 10, 15, 20, 25 menit. Nilai EI digunakan untuk mencari nilai DI. Selanjutnya dibuatkan grafik dan dilakukan pengujian berupa uji regresi untuk mengetahui hubungan luas bidang penyinaran terhadap EI dan delay time processing terhadap EI. Dilakukan juga uji analisis jalur untuk mengetahui hubungan luas bidang penyinaran terhadap DI dan delay time processing terhadap DI. Hasil uji regresi menunjukkan luas bidang penyinaran dan delay time processing memiliki pengaruh signifikan terhadap EI. Hasil uji analisis jalur menunjukkan luas bidang penyinaran tidak memiliki pengaruh signifikan terhadap DI, sementara delay time processing dan EI memiliki pengaruh signifikan terhadap DI. Kata kunci: Exposure index, deviation index, delay time processing, luas bidang penyinaran, computer radiografi

“…The larger the SNR value, the easier the signal and noise to distinguish. The SNR value on the application of heel effect anodes with stepwedge images has a significant and very strong influence on CR (Ratini et al, 2020). CNR is a measure of how far the signal can be distinguished from the background.…”

A study has been carried out on the application of anode heel effect (AHE) with stepwedge to variations in X-ray tube voltage on contrast to noise ratio (CNR) on computed radiography (CR) images. Stepwedge used with 21 steps with the addition of a thickness of 1.5 mm each step. X-ray tube voltage variations are 40kV, 50 kV, 60 kV, 70 kV, 80 kV, and 90 kV. Analysis of the variation of the X-ray tube voltage on the CNR value was determined using IMB SPSS Statistics 26 with a simple regression test. The results of these tests indicate that the variation of the X-ray tube voltage affects the CNR value, where the greater the variation of the X-ray tube voltage, the lower the CNR value. The CNR value at a thickness of 27.0 mm is the optimal CNR value of 71.113
