Abstract

The objective of this study is to describe and analyze the relationship between disaster knowledge and environmental leadership in dealing with floods and with flood disaster preparedness behavior in \with a total of 10,688 people. The sample was taken using a multistage proportional random sampling technique, namely choosing a village that was used as the sampling area and then choosing an area that was very prone to flooding, so that the Awio Village was selected with a sample of 30 respondents. The questionnaire consists of three instruments, namely the flood preparedness behavior instrument (30 questions), the disaster knowledge instrument (26 questions) and the leadership instrument (29 questions). Rating scale with five answer choices that have the lowest value of 1 and the highest value of 5, namely for positive statements and for negative statements otherwise. The results showed the relationship between knowledge and leadership simultaneously (F=280,802,sig=0,000, p0,05). The partial relationship of disaster knowledge contributes individually and significantly to disaster preparedness behavior (ꞵ=0.097, sig=0.028, p0.05) and leadership also contributes individually and significantly to disaster preparedness behavior (ꞵ=0.954, sig=0.000, p0.05). The results showed that the level of community knowledge was still low, because they did not know about the causes of the flood disaster (60% of respondents), the level of leadership was still low, it was seen that disaster preparation planning had never been carried out (50% of respondents), and the behavioral dimension was still relatively low with the percentage behavior does not care about the preservation of nature (40% of respondents). The study recommends collective leadership so that each individual will complement each other according to their strengths, so that it will increase the effectiveness of each phase of disaster management that has been planned.

Abstract

This study aims to determine the differences in daily behaviour and home range of male and female rehabilitated Javan slow loris (Nycticebus javanicus) in Gunung Sawal Nature Reserve, Ciamis, West Java, Indonesia. The study was conducted on four individuals of Javan slow loris rehabilitates (two adult males and two adult females) during their post-released monitoring period. Those animals were fitted with a radio transmitter and were monitored for their daily behaviour and home range for six months (May - October 2018). The focal animal sampling method was employed for daily behaviour observation. The home range of each individual was estimated by Minimum Convex Polygon (MCP) and Kernel Density Estimation (KDE) methods. Data analysis was descriptively displayed in maps, tables, and figures. According to the statistical analyses of the Mann Whitney U test, there are no significant differences (μ = 1,074,554.5 [p 0.01]; P-Value 0.238 0.01) in the daily behaviour of male and female Javan slow loris rehabilitate. In contrast, the home range (vertically and horizontally) of female and male Javan slow loris rehabilitate are significantly different (μ = 816,286.0 [p 0.01]; P-Value 0.000 0.01).   Penelitian ini bertujuan untuk mengetahui perbedaan perilaku harian dan wilayah jelajah kukang jawa (Nycticebus javanicus) jantan dan betina hasil rehabilitasi di Suaka Margasatwa Gunung Sawal, Ciamis, Jawa Barat, Indonesia.
