Human Development Index (HDI) of the Fisherman Community in Ransang Island Indonesia

HDI of fisherman communities is an important indicator to measure the success of developing the quality of life of fisherman communities. HDI is used to see the development of fisherman communities in the long term. This research was conducted in May-August 2021 in Ransang Island, Meranti Islands Regency, Riau Province, Indonesia. This study used a survey method, the sampling method was carried out by multi-stage cluster sampling as many as 40 fisherman spread over several sub-districts. Data analysis for determining HDI is calculated based on the geometric mean of the health index, knowledge index and expenditure index which refers to the UNDP calculation model. The HDI value of the fisherman community of Ransang Island in 2020 was 57.83. The HDI value is composed of a Health Index of 75,08; Education Index of 62,57; and the Expenditure Index of 45,88. The value of the health index is influenced by child mortality. The low Education Index is caused by accessibility, facilities and infrastructure constraints and costs. The expenditure index value is influenced by low productivity, one of which is the impact of the Covid-19 pandemic. HDI of fisherman communities is an important indicator to measure the success of developing the quality of life of fisheries communities. HDI is used to see the development of fisheries communities in the long term.

Estimation of Physiological Cost Index as an Energy Expenditure Index using MacGregor’s Equation

Introduction: Physical activity and energy expenditure can be quantified by measuring heart rate, oxygen uptake and respiratory quotient. The Physiological Cost Index (PCI) proposed by MacGregor is a simple and straightforward method to estimate the energy expenditure index. Here, we aim to estimate the energy expenditure among young Asian population using MacGregor’s equation. Methods: A total of 50 young randomly selected healthy females performed 50m, 100m and 150m walking test at their self-selected preferred speed. The physiological cost index values for 100 m walk at speeds slower and faster than the preferred speed were also obtained. The physiological cost index during exercise was calculated using MacGregor’s equation considering heart rate and speed of walking over the varying distances. Results: The PCI values on three different distances are consistent during self selected preferred speed. The PCI estimation on second and third tests for all three distances walked consistently reproducible. However for each distance walked, the first test the PCI was significantly higher than the second and third test values. The PCI values increased significantly when subjects walked either slower (p = 0.02) or faster (p = 0.001) than their normal preferred speed. Conclusion: The physiological cost index values were similar for varying distances walks. The PCI was the least at the preferred speed of walking and increased when the subjects either walked slower or faster than the preferred speed. The first estimation was higher than subsequent estimations. Keywords: energy expenditure index; exercise; physiological cost index. | PubMed
