Abstract

Tujuan penelitian ini adalah untuk mengetahui proses, perancangan, dan menciptakan value-added sistem informasi pemasaran di PT Global Kapital Investama Berjangka. Data yang digunakan adalah data primer. Metode pengumpulan data berupa observasi langsung ke objek penelitian yaitu PT Global Kapital Investama Berjangka. Hasil penelitian yaitu proses pemasaran di perusahaan ini menggunakan system yang manual. Prosedur sistem informasi pemasaran ini diawali dengan client menanyakan informasi kepada sales administrasi/pegawai PT Global Kapital Investama Berjangka terkait informasi mengenai cara melakukan investasi pada Perusahaan ini. Informasi yang ditanyakan oleh client dilakukan dengan media elektronik. Informasi tersebut ditampung oleh sistem dan setelah data tersebut di masukkan ke sistem, informasi itu diterima dengan baik oleh client dan akhirnya client tertarik melakukan investasi pada perusahaan ini. Client selanjutnya melakukan pendaftaran dan selanjutnya sales melakukan follow up kembali kepada client mengenai data diri yang masih harus diisikan lagi karena data diri ini sangat detail dan dibutuhkan data yang lebih valid. Client disuruh membuat sebuah akun email dan passwordnya. Setelah akun tersebut dibuat, akun tersebut harus di verifikasi dan verifikasi akun dilakukan dengan diberikan melalui sebuah link dan dikirimkan kepada e-mail client dan client harus melakukan verifikasi data dengan membuka link yang diberikan. Data diri client yang baru kemudian diajukan kepada wakil pialang dan wakil pialang akan membuatkan form pembayaran pertama (top-up) yang harus dilakukan oleh setiap client yang baru. Selanjutnya, client melakukan pembayaran pertama kali dan bukti pembayaran diberikan kepada wakil pialang. Wakil pialang lalu meneruskan datanya kepada sales untuk dibuatkan kuitansi pembayaran. Setelah semua proses dilalui, data diri client dan laporan pembayaran client (laporan) diberikan kepada manager untuk di cek dan di approved. Lalu laporan tersebut disimpan di dalam sistem yang telah dirancang. Penulis melakukan rancangan sistem menggunakan alur data flow diagram (DFD). Setelah semua hal dilalui, proses selanjutnya adalah menggambarkan rancangannya secara sederhana.Terlihat perbedaan jumlah biaya antara sistem lama dan baru yang cukup signifikan. Pada sistem lama jumlah yang dikeluarkan dalam jangka waktu tiga bulan adalah Rp 2.273.097.914,- sedangkan sistem baru dalam jangka waktu tiga bulan adalah Rp 1.206.150.000,-. Biaya yang dihasilkan pada sistem baru terlihat lebih rendah daripada sistem lama karena terdapat pengurangan pemakaian alat tulis kantor seperti kertas, tukang servis komputer, dan install ulang komputer. Perbedaan jumlah tersebut di karenakan adanya proses penambahan nilai yang diberikan oleh sistem baru.

Abstract

Bibliometric analysis is a quantitative method used to measure and analyze scientific literature. This technique involves the collection and analysis of publication data, such as journal articles, books, and conferences, to evaluate and understand patterns of scientific communication, research productivity, author collaboration, journal impact, and trends within a scientific field. Bibliometric analysis has a limitation in that it is challenging to visualize effectively, necessitating the use of software for proper visualization. Therefore, this article discusses bibliometric analysis on spline regression for trend mapping and strategy development using VOSviewer software. The research results show that the visualization of spline regression keywords with VOSviewer can help in understanding patterns of relationships between variables, research trends, and network structures in scientific literature. Based on the analysis results, bibliometric analysis on spline regression can be visualized in trend mapping, which can aid in planning further research strategies, including identifying collaboration opportunities and underexplored research areas.

Abstract

Investment is a commitment of funds or other resources made with the goal of obtaining profits in the future. Gold is one of the commodities favored by investors because of its relatively stable value. Although relatively stable, gold prices experience fluctuations, which introduce risks associated with gold investments. The pattern of gold prices can be mathematically modeled using Support Vector Regression (SVR). SVR finds a function as a hyperplane (separating line) in the form of a regression function that fits all input data with an error and minimizes it as much as possible. SVR enables a balance between data fitting and overfitting through the use of kernel functions. The pattern of gold prices and SVR is the main focus of this research, aiming to model gold prices effectively. Furthermore, SVR seeks to obtain a hyperplane (regression function) that fits all input data by minimizing errors. The gold price modeling results using SVR indicated that the best model was obtained with a linear kernel, showing an error of 0.73% with parameters C = 10^(-4) and ? = 10^(-4). This implies the model's strong ability to follow data patterns accurately, resulting in highly reliable forecasting.

Abstract

This study aims to analyze the relationship between the neutrophil lymphocyte ratio (NLR) and the incidence of acute appendicitis in patients at Ibnu Sina Hospital, Gresik Regency, in the 2022-2023 period. Acute appendicitis is a frequent emergency surgical condition, especially in adolescents and young adults, with the risk of complications such as perforation and peritonitis. NLR, as an indicator of inflammatory response, is considered more practical and economical than CT scans and ultrasounds, which have limited cost, accessibility, and risk of radiation exposure. This study used an observational analytical method with a cross-sectional approach on 51 appendicitis patients who underwent appendectomy. NLR data was obtained through routine blood results, with statistical analysis using SPSS to test the normality and difference in NLR values between uncomplicated appendicitis and appendicitis with complications. There was a significant difference in the mean NLR value between patients with complementary and non-complementary appendicitis, with a p < value of 0.001. The results of the ROC Curve analysis show that NLR has a high prediction value in predicting complementary appendicitis of 97.5%. This study concludes that NLR can be an effective indicator in distinguishing cases of complementary and non-complementary appendicitis and the potential of NLR as an easy and efficient screening tool in the treatment of acute appendicitis, especially in health facilities with limited resources.
