Abstract

Land Surface Temperature (LST) is average temperature of an element of the exact surface of the Earth calculated from measured radiance which depends on the albedo, the vegetation cover, and the soil moisture. Land Surface Temperature can affect human discomfort, health problem, higher energy bill and further reduce the habitability of urban and sub urban area as Makassar city has been recently undergoing massive urban development. This study tries to monitor and estimate Land Surface Temperature by using Landsat 8 TIRS and the data analyzed by vegetation index, and temperature index in order to derive Land Surface Temperature value. The result shows that the vegetation area declined around 3470 hectares in the last four years while the urban area increased approximately 1509 hectare. In addition, 2015, Makassar, South Sulawesi, Indonesia are experienced the highest temperature at 32 degree Celsius while 2019 shown that the maximum heat reached 29 degree celsius. However, the moderate and high temperature (26 – 29 degree Celsius) in 2019 expand and cover wider area than in 2015 as the area of vegetation declined and built-up area increased significantly

Abstract

Manokwari Regency is one of the districts in West Papua Province which has the potential for moderate to high Tsunami vulnerability. One of the vulnerable districts is East Manokwari District. Potential disaster vulnerability in an area should be followed by community preparedness. This is because when a disaster occurs, the community already understands what steps to take. This study aims to determine the level of overall preparedness of the community in Pasirido Village, East Manokwari District. This research was conducted for one month in January 2021 in Pasirido Village, East Manokwari District, Manokwari Regency. This research uses quantitative methods. The sample was determined using the method of puposive sampling with the category of the head of the family and has lived for 10 years in Kampung Pasirido so that a total sample of 30 respondents. Data collection was carried out by distributing questionnaires and interviews to respondents. The questionnaire used is a standard from LIPI-UNESCO / ISDR 2006 with parameters of knowledge and attitude (KA), emergency response plan (EP), disaster warning (WS), and resource mobilization (RMC). The results showed that the level of community preparedness on the parameters of knowledge and attitude was mostly in the very ready category of 67%. The level of community preparedness in the parameters of the emergency response plan was mostly in the very ready category of 60%. The level of community preparedness for disaster warning parameters in the very ready category was 93%. The level of community preparedness on the parameter of resource mobilization was mostly in the ready category of 80%. Based on these four categories, overall community preparedness for flood disasters is included in the very ready category of 77%. The recommendation of this study is the need to increase community preparedness by conducting training to simulations from related agencies to the community. This is so that all people in Pasirido Village are in the category of being very prepared to face the Tsunami disaster.

Abstract

Hubungan antara pola aliran dengan struktur geologi erat kaitannya sehingga perlu dianalisis. Struktur geologi yang terbentuk di permukaan merupakan hasil dari kinematika mekanisme struktur geologi suatu daerah. Struktur geologi tersebut merupakan bidang lemah yang memiliki pola, di mana dapat mengakomodasi jalur air yang mengalir di permukaan. Saluran air akan mengikuti pola struktur yang berkembang, sehingga saluran air tersebut juga memiliki pola yang dapat dikelaskan sesuai dengan klasifikasi pola aliran air. Tujuan penelitian ini untuk membuktikan kesesuaian hubungan antara pola aliran air dengan struktur geologi yang berkembang di daerah penelitian, sehingga analisis pola aliran air dapat digunakan sebagai data awal untuk menginterpretasi struktur geologi yang berkembang pada suatu daerah. Penelitian dilakukan di Kampung Klaka dan sekitarnya, Distrik Maudus, Kabupaten Sorong, Provinsi Papua Barat dari Agustus 2020 – Juni 2021. Metode yang digunakan berupa analisis pola aliran air dan pemetaan geologi permukaan. Hasil penelitian menunjukkan bahwa hasil analisis pola aliran air di daerah penelitian sesuai dengan hasil pemetaan struktur geologi, di mana pola aliran air yang mengindikasikan adanya struktur sesar dan lipatan terbukti sesuai dengan temuan struktur geologi hasil pemetaan geologi di daerah penelitian.

Abstract

One of the most important activities in landslide risk management is mapping the level of landslide threat. The objective of this research was to map the level of landslide threat in the Ransiki District. This study was carried out in the Ransiki District, South Manokwari Regency, West Papua Province from May to November 2021. Lithology, Geological Structure, Rainfall, Land Use, and Slope were the parameters used in this study. The stack plate method was used, and the analytical hierarchy process (AHP) method was used for parameter weighting. This AHP was used to calculate the weight of each parameter class and landslide disaster parameter. The landslide threat level was mapped using ArcGIS 10.1 software. According to the research findings, there were three levels of landslide threat in the Ransiki District, South Manokwari Regency. The low threat level covered 6,792.06 hectares, or 37.52% of total area of Ransiki District. The Ransiki District has a moderate threat level covered 6,741.33 hectares, or 37.24% of its total area. Ransiki District had a high threat level of 4,567.85 hectares, or approximately 25.24% of its total area. This study provided suggestion that in areas with moderate and high threat levels, more research can be conducted to reduce the impact and losses caused by landslides
