Chi-Square Histogram Analysis of Woven Fabric Images Made from Natural Dyes Due to Exposure to Sunlight

This research aims to conduct a Chi-square analysis on the histogram of woven fabric images dyed with natural dyes following exposure to sunlight. Woven fabrics dyed with natural dyes have attracted attention in the textile industry due to their sustainability and environmental safety. Continuous sunlight is a significant factor influencing color changes in woven fabric dyed with natural dyes. The methodology involves capturing images of woven fabric pre- and post-sunlight exposure, followed by histogram analysis using Chi-Square testing, mean, mode, and standard deviation. We utilize pre-cropped and resized grayscale images. Research findings demonstrate that sunlight significantly impacts the histogram of woven fabric images dyed with natural dyes, causing shifts in color distribution, standard deviation, and mode. These findings hold critical implications for the textile industry, particularly for manufacturers of woven fabrics dyed with natural dyes. The application of Chi-Square analysis and standard deviation provides guidelines for product design, maintenance procedures, and consumer education regarding the preservation of color quality in fabrics exposed to sunlight. Changes in the quality of woven fabric images under sunlight exposure can offer essential guidance in the care and maintenance of textile products dyed with natural dyes. This research contributes to a deeper understanding of the interplay between natural dyes, sunlight, and woven fabrics, supporting the development of sun-resistant natural dyes

Aplikasi Pembayaran Iuran Sekolah Katolik Yayasan Sagrado Coração de Jesus Berbasis Web

The Sagrado Coração de Jesus Foundation is a formal educational institution that manages 58 Catholic schools in the Maliana Diocese of Timor Leste. In dealing with the payment of fees, Catholic schools under the Sagrado Coração de Jesus Foundation still use books to record payment transactions. These transactions must be carried out at the foundation, and it takes a long time to record transactions in the book so that it becomes a problem faced by the foundation, schools, and parents of students. A web-based school tuition payment application is needed by the Sagrado Coração de Jesus Foundation to handle the school's tuition payment activities on behalf. The use of website media makes it easier for parents to show proof of payment without having to come to the foundation. Applications that are built can also speed up the process of recording the payment of contributions by foundation employees. Based on the research results, the Web-based application for payment of tuition fees for Catholic schools at the Sagrado Coração de Jesus Foundation makes it easier for parents and foundations to make payment transactions more efficiently and quickly.Yayasan Sagrado Coração de Jesus adalah sebuah lembaga pendidikan formal yang mengelola 58 sekolah Katolik di wilayah Keuskupan Maliana Timor Leste. Dalam menangani kegiatan pembayaran iuran, sekolah-sekolah Katolik yang bernaung di bawah Yayasan Sagrado Coração de Jesus masih menggunakan buku untuk mencatat transaksi pembayaran. Transaksi tersebut wajib dilakukan di Yayasan serta dibutuhkan waktu yang lama untuk mencatat transaksi di buku sehingga menjadi masalah yang dihadapi oleh pihak yayasan, sekolah, maupun orang tua siswa. Sebuah aplikasi pembayaran iuran sekolah berbasis web dibutuhkan oleh Yayasan Sagrado Coração de Jesus untuk menangani kegiatan pembayaran iuran sekolah-sekolah milik yayasan. Penggunaan media website memudahkan orang tua untuk menunjukkan bukti pembayaran tanpa harus datang ke yayasan. Aplikasi yang dibangun juga dapat mempercepat proses pencatatan pembayaran iuran oleh pegawai yayasan. Berdasarkan hasil penelitian, aplikasi pembayaran iuran sekolah-sekolah Katolik di Yayasan Sagrado Coração de Jesus Berbasis Web memudahkan orang tua serta yayasan dalam melakukan transaksi pembayaran yang lebih efisien dan cepat

Visualisasi Hasil Produksi Pangan di Provinsi Nusa Tenggara Timur

The Department of Agriculture of the Province of East Nusa Tenggara (NTT) is a regional apparatus with the main task of providing services to the community in the agricultural sector, one of which is food coverage. The website http://distan.nttprov.go.id does not yet contain information about food production results that are complete and clear. To overcome these problems, it is necessary to build a Food Production Results Visualization which is expected to display a picture of food production results based on the year of production, types of commodities and production results from each district in the province of East Nusa Tenggara that is easily accessed and understood by the public.

Artificial Neural Network-Based Prediction Model Back Propagation on Blood Demand and Blood Supply

The balance between blood demand and supply at the Indonesian Red Cross Blood Transfusion Unit (UTD-PMI) is crucial. This condition must be maintained to reduce unused or expired blood supplies. Despite the situation in UTD-PMI, where the blood supply exceeds demand, there is still a shortage of blood when needed by patients. This research aims to model the prediction of blood demand and supply for each blood type using the Back Propagation artificial neural network approach. Data from the last 3 years, from 2020 to 2022, were utilized in this research process. There are three stages in this research process. The first stage involves the training process, using data from January 2020 to December 2021. The testing process utilizes data from January 2021 to December 2022. The prediction process involves displaying the forecasted data for the next 12 months from January to December 2023. The accuracy of the calculations is assessed using the mean square error (MSE). Ultimately, the research results present the prediction model for the four types of blood with respect to the demand and supply. These findings can serve as a reference to regulate future blood donation activities carried out by the UTD-PMI
