Cloud Radio Access Network (C-RAN) is known as cloud radio computing which uses a centralized Base Transceiver Station (BTS) connected to a cellular antenna to process the signal and then transmit it to the core network. A fair network can be used to reduce the costs offered. The aims of this study are to formulate a fair network-based C-RAN model which is added with the modified cobb-douglas u…
The updated IRC (Improved Reverse Charging) model discussed in this study explains the combination of the IRC model and the bundling model in the wireless internet financing scheme to get the optimal solution. IRC can be interpreted as the ability of a network to replace the network that is being used when the network is suddenly lost. Bundling is a strategy of combining two or more products wi…
Supplier selection is an important stage in procurement activities. In selecting suppliers, there are several criteria that must be considered, namely price, quality and on time delivery. Price, quality, and on time delivery are goals in the matter of supplier selection. The value of the goal of price, quality, and timeliness for each offer varies so that it cannot be stated with certainty, so …
Hospital emergency room is one of the facilities that is often accessed by the public in an emergency situation. The importance of a hospital that has emergency room facilities is in an appropriate location and easily accessible to the public to reduce the risk of death. Currently, there are 23 hospitals that have emergency room facilities, which are spread across 13 of the 18 districts in Pale…
Cans are storage places for food and non-food items made of aluminum. Canned waste is difficult to decompose on the ground so that a recycling process needs to be carried out so that it does not cause problems for the environment. The process of grouping the cans is the initial process in recycling. This study classifies cans based on RGB images using the Decision Tree. The decision tree explai…
Chicken eggs are distributed by suppliers (Aguan Shop) to 17 retailers in Palembang city. Traffic conditions, road conditions and vehicle conditions greatly affect distribution activities. Uncertain travel time results in uncertain costs. This problem is solved using a fuzzy model. There are two objective functions, namely minimizing costs and minimizing delivery time. This study discusses Opti…
Survival analysis is a statistical procedure related to the time from the start to the time of occurrence of the event. Survival analysis is usually used to analyze risk factors associated with clinical events such as patient survival time, recovery time, relapse time or death at a certain time. There are two types of hazard regression models that can be used, namely the multiplicative hazard m…
Cutting Stock Problem (CSP) is a problem of cutting raw materials in the field of optimization. This study implemented the preprocessing technique in the Arc Flow model on CSP. The function of preprocessing techniques is to strengthen constraints and improve variables, so that many or excessive constraints can be eliminated but still produce optimal solutions. There are 3 stages in the applica…
Corn (Zeamays L) is one of the most important carbohydrate-producing foodstuffs in the world besides wheat and rice. Corn plants are sensitive to pests and diseases which can result in a decrease in the quantity and quality of the production. Eradicate pests and diseases according to their type is a solution to overcome the problem of disease in corn plants. The purpose of the research to class…
The use of credit in this day and age has been increasing from the bottom to the top. The level of credit risk is also higher due to the failure or inability of the customer to return the loan amount obtained from the bank and its interest in accordance with the scheduled period. So it takes a computer system that can study historical data from credit lending effectively. The Naive Bayes method…
The Improved Reverse Charging (IRC) model in this study was developed by adding a bundling model to the wireless network pricing scheme by considering the function of perfect substitute utilities in the case of homogeneous consumers which aims to obtain maximum profit and increase the level of consumer satisfaction. The IRC-bundling model is solved as Mixed Integer Non-Linear Programming (MINLP…
Endometriosis merupakan salah satu penyakit pada wanita usia subur yang ditandai dengan tumbuhnya sel endometrium di luar rongga rahim. Penelitian ini bertujuan untuk memprediksi Hazard kumulatif kekambuhan endometriosis dengan metode nelson aalen. Selanjutnya digunakan uji log rank membandingkan fungsi survival berdasarkan faktor risiko yaitu jenis operasi, jenis endometriosis, waktu olahraga,…
Dalam penanganan gejala diabetic retinopathy, diperlukannya pendeteksian terhadap pembuluh darah pada retina. Proses pendeteksian ini memerlukan ketelitian yang sangat tinggi dan terkadang citra memiliki kualitas rendah dan noise yang membuat pendeteksian sangat sulit untuk dilakukan dengan tenaga medis. Dikembangkanlah model machine learning yang mampu melakukan segmentasi pada bagian pembuluh…
This study intends to formulate new modified model which is more optimal than the original model on internet pricing scheme. Bundle pricing described is in form of original model in this study and will be modified with Quality of Service (QoS) which has four pricing strategy models, and Cobb-Douglas utility function for heterogeneous High-End and Low-End consumer. Because of these four pricing …
