Abstract

According to a study published in the International Journal of Cardiology titled "Heart failure across Asia: Same healthcare burden but differences in organization of care," the mortality rate due to heart failure in Indonesia is relatively high. The research findings indicate that approximately 5% of the total population in Indonesia suffers from heart failure. Heart disease is a condition that occurs when the heart experiences disruptions, either due to infections or congenital abnormalities. It is important to pay attention to heart disease in order to reduce the mortality rate. However, there are several inaccuracies in identifying heart disease, and it is necessary to perform calculations using a predictive approach utilizing data mining techniques. One of the data mining methods used is the Naïve Bayes (NB) algorithm, which serves as a classification technique. Additionally, before performing the classification, issues with the data content are often encountered, such as the presence of missing values. This problem can interfere with the classification process; therefore, a special technique called pre-processing is needed to remove missing values. By employing this technique, it can support obtaining accurate prediction results. Furthermore, to support the classification, this study applies feature selection using the Backward Elimination (BE) method to enhance accuracy. In this study, through the implementation of data pre-processing techniques and feature selection, the accuracy rate was successfully improved to 98.31%.

Abstract

The problem of Overdimension and Overloading (ODOL) freight transportation has become a national issue.  Various impacts caused by ODOL freight transportation include a decrease in vehicle speed, a decrease in road technical life, loss of road maintenance budget, vehicle damage, and the occurrence of traffic accidents on the road. East Java Province has a fairly high economic activity by using freight transportation in various conditions including Overdimension and Overloading. The Ministry of Transportation through the UPPKB Service Unit throughout East Java has made various efforts to handle ODOL freight transportation, but the level of violations of freight transportation still occurs. This study aims to determine the factors that affect the effectiveness of handling Overdimension and Overloading (ODOL) in freight transportation so that it can provide recommendations for appropriate ODOL handling. The data collection method used interviews and questionnaires to Korsatpel, UPPKB Operational Staff, and freight transport drivers. While the analysis method used fishbone diagram analysis and multiple linear regression analysis using field data. Based on the results of the study, it is known that the dominant factors that affect the effectiveness of handling Overdimension and Overloading (ODOL) in freight transportation are the enforcement of Tilang (X1) and Transfer of Cargo / Transfer of Excess Load (X3) with the value of coefficient determination at UPPKB Trosobo and Singosari of 96.1% and 92.3%. The handling recommendations given are the need to increase ticket fines and provide transportation services for excess cargo in the form of vehicles and transportation personnel as well as forklifts and cranes at the UPPKB Satpel to move heavy loads.

Abstract

A disaster is an event that can be predicted but cannot be known with certainty when it occurs. Recently, the intensity of natural disasters has increased, in the form of landslides, floods, earthquakes, tidal waves, typhoons, and volcanic eruptions. This needs to be watched out for everyone, including users of public facilities. Currently, there are not many public facilities that are friendly to disasters, one of which is the passenger terminal. This study aims to determine the potential vulnerability of terminal buildings and analyze the availability of terminal infrastructure facilities and the need for terminal infrastructure facilities based on disaster mitigation. The method used in the analysis of the needs of terminal infrastructure facilities is observation, interviews, and questionnaires, while to determine the potential vulnerability of terminal buildings using the Rapid Visual Screening (RVS) worksheet issued by FEMA 154-2015.

Abstract

The development of the construction world today, especially in EPC (Engineering, Procurement and Construction) project work is very rapid and complex. So the level of difficulty and the potential for delays is quite large. From data taken at one of the EPC divisions of construction companies in Jakarta in March 2023, there are 9 projects that experience delays from 10 existing projects. So the purpose of this study is to identify and analyze the main factors causing delays in completing EPC projects as well as alternative completion. In achieving good project time performance, it requires the support of resources (Man, Material, Machine, Money, Method) that are owned efficiently from the input process to the output. The method used in this study is DMAIC (Define, Measure, Analyze, Improve & Control) where analysis is carried out using Fishbbone, 5W + 1H Brainstorming and Pareto Diagram. The main factors causing delays in EPC project work are lack of material supply, lack of manpower, late material arrival schedule, damage or loss of materials, lack of experts and design errors during planning. Alternatives to solving EPC project delays are first submitting an EOT (Extention of Time), adding man power, evaluating schedules, monitoring the implementation of engineering designs, and collaborating with consultants who are more experienced in the EPC field so that there are no planning design errors and implementation methods.
