Abstract

Investors in investing are always accompanied by a sense of tolerance for the risk of funds invested in an asset. Each investor has a different form of risk tolerance, depending on the function of the utility. This paper aims to conduct a theoretical study of the forms of investor risk tolerance for several utility functions. This study is carried out by reviewing several utility functions which include: square root utility, cubic fraction utility, quadratic utility, exponential negative utility, and logarithmic utility. Based on the results of the study for each of these utility functions, successively obtained risk tolerance in the form of linear, linear, linear, constant, and linear. Linear risk tolerance illustrates that an investor changes the value of his investment in line with changes in the level of risk faced.

Abstract

In the oil production distribution network, there are three main nodes, namely the supply node, the transshipment node, and the demand node. The pattern of distribution of oil production from the supply node to the demand node is very diverse and can affect the costs to be incurred. Therefore, a company must be able to determine the right distribution pattern, so that the costs incurred are optimal. This paper intends to conduct a study of how to determine and calculate the distribution patterns and the minimum total costs incurred, using the primal-dual linear program method. Based on the results of the case analysis, it is known that the number of supply commodities will be the same as the number of demand commodities, but the distribution from each source does not necessarily have the same capacity and costs. Therefore, the distribution pattern is determined based on the existing cost and capacity, so that cost optimization can be achieved.

Abstract

Flooding is a natural event, one of which is caused by the overflow of rivers. This disaster often occurs in the Dayeuhkolot area, Bandung Regency. Geographical conditions that are close to the flow of the Citarum River and the plains that are lower than the surrounding area cause this area to be flooded especially during the rainy season. This paper aims to analyze the effectiveness of disaster training given at a young age and analyze the effectiveness of training methods provided in the form of games and PowerPoint media. This activity is aimed at grade 6th students at BojongAsih Elementary School starting with the questionnaire I which functions as a pre-test and ends with questionnaire II which functions as a post-test. Questionnaires were given at the beginning and at the end to see the extent to which the material provided new influence and knowledge to BojongAsih Elementary School students. The results of the questionnaire showed that before counseling about flood mitigation, samples were categorized as having a good knowledge of 91% and having poor knowledge of 9%. After counseling about flood disaster mitigation using games and PowerPoint media there was an increase in knowledge, samples that had good knowledge were 98% and those with less good knowledge were 2%. Based on the pre-test and post-test results, this activity was proven successful in increasing the knowledge of BojongAsihElementary School related to flood mitigation.

Abstract

In the face of investment risk, investors generally diversify and form an investment portfolio consisting of several assets. The problem is the fiery proportion of funds that must be allocated to each asset in the formation of investment portfolios. This paper aims to study the optimization of the Markowitz investment portfolio. In this study, the Markowitz model discussed is that which considers risk tolerance. Optimization is done by using the Lagrangean Multiplier method. From the study, an equation is obtained to determine the proportion (weight) of fund allocation for each asset in the formation of investment portfolios. So by using these equations, the determination of investment portfolio weights can be determined by capital.

Abstract

West Java noted, as of August 14, 2021, 653,741 people were confirmed positive for COVID-19. On the same date, the number of active COVID-19 cases in West Java was 65,000. There is a significant increase in active cases of COVID-19 in 2021 in West Java. In the period 5 June – 17 July 2021, there was an increase in the number of active cases by 95,532. In that period, active cases increased by 484%, and the Bed Occupancy Ratio (BOR) in West Java had jumped in June 2021 with the highest number of 91.6%, this figure far exceeded the WHO recommendation of 60% before finally continuing to decline and finally in August was at 30.69%. This has an impact on the incidence of patient rejection at the COVID-19 referral hospital. Active cases talk about COVID-19 patients who need medical treatment and new cases talk about the rate of spread of COVID-19 in West Java, so these two things are very strategic to study. In this study, active cases and new case were predicted using Multilayer Perceptron (MLP). The data used in this study were sourced from the COVID-19 Task Force. The data is the number of positive cases, recovered and died of COVID-19 sufferers in 34 provinces in Indonesia in the period 2 March 2020 - 14 August 2021. The results of the study found, from the results of the evaluation using data testing the number of active cases in the last 19 weeks, namely April 10 – August 14, 2021, MLP is accurate in predicting the number of active cases for the first coming week 17 times, and the next two weeks for the second week 12 times with an absolute percentage error (APE) < 20%. As for weekly new cases, MLP has been accurate 10 times for the next one week and 9 times for the next two weeks. It is hoped that the results of this study can be useful for the government as a reference in conditioning the hospital bed capacity to deal with active cases of COVID-19 in West Java in the next two weeks so that no COVID-19 patients are rejected by the hospital because the hospital is full.
