Abstract

Lack of knowledge about the early diagnosis of disease in pregnant women is very risky and can cause death. So it is very necessary to do socialization early to anticipate this. Based on the results of existing surveys if the handling is late, the mortality rate of pregnant women can increase. Then the use of technology and applications to help users (pregnant women) in making diagnoses before meeting with experts to help in knowing and detecting symptoms experienced. To produce the right solution, data from experts on disease diagnosis for pregnant women is needed to be included as a knowledge base in the system. This study uses the approach or method of Certainty Factor (CF), namely by calculating according to the weight given by the expert and the answers given by the user. The aim is to help and provide a level of user confidence in diagnosing diseases with high accuracy. The results of the tests carried out by testing validation and accuracy between expert systems and those carried out by experts obtained a diagnosis with the same CFCombine value ..

Abstract

Technological progress in the Millennial Era is very fast, especially in the business world, it has a very large effect. Information technology is currently growing in line with the needs of millennial children who want convenience. So every college wants to achieve a goal. So to achieve this goal, higher education institutions encourage to establish a Business Unit of the Faculty of Computer Science, Indonesian Methodist University (FIKOM UMI). Therefore we need a system that aims to improve the development of an entrepreneurial culture and improve the academic community. By overcoming these problems, a web-based millennial child accessories sales application was designed by applying the FCFS (First Come First Served) method. The millennial generation is currently a major player in the Indonesian economy. So in the business context, it is very important to understand the millennial character so that they can read product trends that are currently popular. One of the products that can show a person's character is accessories. The results obtained are intended to make it easier for customers to order and purchase a variety of accessories products and prioritize customers who are required to pay then the goods are sent and processed first. The system is built using the HTML and PHP programming languages, and the server uses Xampp and the database uses MySql.

Abstract

This study uses the Support Vector Machine method, where this method aims to obtain a classification model that has high accuracy or small error in classifying an image. The development of the medical world today is closely related and cannot be separated from the development of information technology that continues to grow. To be able to distinguish Magnetic Resonance Image (MRI) images detected by brain tumors, it is necessary to carry out a classification process using the Support Vector Machine (SVM) method. So we need an application for classifying brain tumors to facilitate medical work in determining the type of brain tumor disease. Image processing will use 2 types of brain tumors, namely Glioma and Meningioma

Abstract

Shallot production is threatened by a number of diseases resulting in quite large losses and causing a decrease in shallot quality. One of the main diseases that attack shallots is purple spot disease and another common disease on shallots is lanas. Therefore it is necessary to classify the diseases of shallots in order to know the type of disease that attacks shallots. Shallot disease can be seen from the shape of the leaves and the texture of the leaves is the most appropriate feature used in the identification of shallot disease. However, the various forms of shallots are not easy for humans to detect, especially for ordinary farming communities. Therefore, technology can help detect shallot disease through leaf texture with the K-Means method using matlab. Based on the results of the identification test with test data as many as 20 images managed to get an accuracy value of 80%, where this accuracy value can be said to be good

Abstract

Habitat Coffee adalah salah satu kafe yang menawarkan berbagai jenis menu minuman dan makanan dengan harga yang beragam yang disajikan kepada pelanggan. Habitat coffee dapat menjual ratusan transaksi dalam sebulan yang mengakibatkan penumpukan data transaksi yang kerap tidak digunakan dikarenakan terbatasnya waktu dan jumlah data yang besar sehingga sulit dalam pengelolaan data. Untuk mengubah penumpukan data transaksi tersebut menjadi sebuah informasi tentang menu yang dibeli pelanggan secara bersamaan maka dibutuhkan sebuah metode atau teknik sehingga pihak Habitat Coffee dapat berinovasi dengan membuat paket menu makanan baru yang dapat meningkatkan keuntungan penjualan karena dapat menjual banyak menu dalam sebuah paket makanan dan mengetahui bahan baku apa saja yang harus di siapkan atau disediakan menggunakan teknik data mining yaitu metode algoritma apriori. Dari pengujian yang telah dilakukan sebanyak 4 kali menggunakan 150 data transaksi dengan menetapkan nilai minimum support, minimum confidence serta lift ratio untuk menentukan tingkat kevalidan suatu aturan maka menghasilkan kombinasi menu yaitu jika membeli lontong spesial maka akan membeli es teh manis dan kentang goreng, jika membeli nasi soto betawi maka akan membeli es teh tawar dan es teh manis.

Abstract

Teknologi informasi memegang peranan penting dalam sebuah perusahaan atau instansi lainnya, namun untuk melihat kesesuaian teknologi dengan kebutuhan perusahaan diperlukan evaluasi tata kelola teknologi informasi. Pada penelitian yang dilakukan, fokus evaluasi meliputi divisi Data Management PT Telkom Gaharu dengan menggunakan kerangka kerja COBIT 2019 dengan domain EDM04 (Ensure Resources Optimization), MEA01 (Managed Performance and Conformance Monitoring) dan DSS03 (Managed Problems) yang berfokus pada sistem informasi yaitu Unified Inventory Management. Penelitian ini menggunakan teknik pengumpulan data studi literatur, observasi, wawancara dan kuesioner yang dikelola menggunakan pengukuran skala Guttman dengan bantuan perhitungan Microsoft Excel. Evaluasi yang dilakukan berfokus pada nilai Capability Level dan Gap Analysis yang disajikan dalam bentuk Tabel dan Grafik Radar. Nilai Capability Level dari domain EDM04 sebesar 92% (Fully Achieved) dengan Gap Analysis 0.97 maka dapat dikatakan bahwa proses tata kelola teknologi informasi untuk domain EDM04 sepenuhnya sudah tercapai. Nilai Capability Level domain MEA01 sebesar 94% (Fully Achieved) dengan Gap Analysis 1.33 maka dapat dikatakan bahwa proses tata kelola teknologi informasi untuk domain MEA01 sepenuhnya sudah tercapai. Nilai Capability Level domain DSS03 sebesar 81% (Largely Achieved) dengan Gap Analysis 0.25 maka dapat dikatakan bahwa proses tata kelola teknologi informasi untuk domain DSS03 sepenuhnya sudah tercapai.

Abstract

Indonesia's plantation sector, especially palm oil, has a high selling value and its attractiveness continues to increase. The price of palm oil is strongly influenced by external factors, especially the price of crude oil (CPO) and palm oil production globally. Unstable price fluctuations have become a challenge for companies such as PT Bakrie Sumatera Plantations, Tbk. in planning harvest time and optimizing profits. To overcome this uncertainty, this study proposes the use of the Multiple Linear Regression method to predict palm oil prices. Price and production data from 2021 to 2023 are the main basis for developing the prediction model. In this study, 4 independent variables were used, namely year, month, oil price and total production. The amount of data used in this study is 33 data. In testing the Multiple Linear Regression method has an RMSE value of 0.24 and the predicted value of palm oil prices from January to December 2024 is the price of palm oil with the highest value in January 2024 of Rp. 2,276.931 / kg and with the lowest value in December 2024 of Rp. 1,474.75 / kg.
