Abstract

The coastal area as a densely populated area with high socioeconomic activity is currently experiencing impacts in various sectors due to the COVID-19 virus outbreak. However, the efforts to minimize the impact of the pandemic are still general and have not taken consider the conditions of communities in coastal areas. This analysis aims to determine the factors that cause the coastal community of Kenjeran to experience a decline and a decrease in trade and economic activity and identify the probability during the COVID-19 pandemic. The method used in this analysis is Fault Tree Analysis (FTA). The result shows that the main factors causing the decline are decreased fish sales, decreased community income, decreased activity at sea, and decreased activity of traders in the market with the probability factor of 0.2494 or 24%. Mitigation recommendations for the coastal community of Kenjeran Beach are a collaboration between the fishers and the policy of cooperation between the trade office and the marine service to conduct clustering for fishers so that they can supply scarcity of marine fish and limited marine product, also monitoring the health protocols with the swab and rapid tests for traders by permanent health service

Abstract

Since the COVID-19 pandemic hit Indonesia, many fishery households on Indonesia's coast have been affected. Therefore, an analysis of the impact of the COVID-19 pandemic was carried out on the health and economy of fisheries households in the coastal areas of Kenjeran Beach, especially in Kedung Cowek Village, Bulak, Surabaya. The Fault Tree Analysis (FTA) method is used to find the probability of decreasing fisheries household welfare and the Event Tree Analysis (ETA) to find the level of risk for each factor causing the decline in the welfare of fishery households. The analysis result shows that 21 factors cause household welfare in Kenjeran Beach to decline, grouped into two intermediate events: decreasing fisheries household income and decreasing fishery household health. The probability of fishery household welfare decreases by 0.0171212. Decreasing welfare of fisheries households has a risk that fisheries household income will not experience a decrease in income, and there is no spread of COVID19, with a risk probability of 0.0052 and having a medium risk index level. Based on this, stakeholders in the income and health of fisheries households such as the government, analytical institutions, and households have a role in mitigating the impact of COVID-19.

Abstract

Optimizing costs and time and manpower planning are very important in project management. The case study raised in this research is a cooling water pipe fabrication project with a processing time duration of 231 days and a project cost allocation of Rp. 306,545,488,000. The method used to control project delays is earned value analysis, and to optimize the project is done by shortening the project duration and minimizing project cost losses using the crash program method. The results of the earned value analysis stated that the project experienced delays, exceeded budget costs and was subject to project delays penalties, which was 340 days of completion time more than 111 days from the planned time and with a total final project cost of Rp.331,813,410,524.46 more than Rp. 25,267,922,524.44 of the costs that have been prepared. Then an effort was made to accelerate the duration of the project with three scenario options. From the results of the crash cost calculation, it is found that the final total cost estimate for scenario 1 with 3 hours overtime is Rp.289,043,553,541. Scenario 2, the estimated total final cost with 4 hours overtime is Rp.289,051,063,021 and scenario 3 the estimated total final cost with the addition of workers is Rp. 289,310.359,861. So, the scenario that can be used by PT. X in order to minimize losses is to impose 3 hours overtime with an estimated total final cost of Rp.289,043,553,541.
