Natural disasters that often occur in coastal areas are tidal floods and river floods. Flood vulnerability management of coastal areas has become increasingly important to mitigate and prevent floods. The purpose of the study was to analyze the socio-economic vulnerability of the Mataram City coast. The spatial-DPSIR approach was employed to study the socio-economic and ecological framework. The socio-economic vulnerability was analyzed using the following parameters: population density, poverty level, livelihoods, land ownership, awareness of disasters, the presence of business areas and trade areas, and physical damage to buildings. The analysis result of the coastal flood socio-economic vulnerability showed that most of the Mataram coast were classified as intermediate. The results of this study are expected to become a reference for development and management, especially in spatial planning policies for a disaster-secure coastal area.
Tujuan penulisan adalah untuk menggambarkan dinamika hubungan patron-klien pada pelaku usaha perikanan budidaya, khususnya antara bakul (pengumpul) dengan langgan (pembudidaya polikultur udang dan bandeng) di Kabupaten Indramayu. Metode penelitian dilakukan melalui pendekatan kualitatif. Analisis data dilakukan dengan pendekatan teori patron-klien dari James Scott (1972). Penelitian dilakukan pada tahun 2012 dengan jenis data yang dikumpulkan adalah data sekunder dan primer. Pengumpulan data sekunder dilakukan dengan cara mencatat dan mempelajari dokumen tertulis dan laporan-laporan, sedangkan data primer diperoleh melalui observasi dan wawancara mendalam dengan para pelaku usaha perikanan budidaya polikultur udang-bandeng yang terlibat dalam pola hubungan patron-klien. Hasil penelitian menunjukkan dalam hubungan patron klien, pengumpul bertindak sebagai pihak patron yang memilki modal (capital), kekuasaan (power), status, wewenang dan pengaruh terhadap pembudidaya (langgan). Pembudidaya merupakan subordinat, diposisikan sebagai klien, yakni sebagai bawahan dari si patron. Hubungan patron-klien ini bersifat dominatif dan sengaja dipelihara patron (pengumpul) agar klien (pembudidaya) menjadi tergantung dan terus menyediakan pasokan hasil budidayanya.
Human population growth, the rapid development of urban areas, and climate change were causing a scarcity of freshwater resources. Providing water and sanitation is important to protect the health during a pandemic. However, North Jakarta still faces problems in meeting the water demands of its residents. The COVID-19 pandemic expands the challenges faced by vulnerable individuals living in poverty and without access to health services, water, sanitation, and adequate housing, especially for women. During the COVID-19 pandemic, woman's responsibilities became even heavier; aside from paying attention to their safety and health, women were often burdened with domestic roles towards their families and their responsibility for collecting water supplies for the household. This study examines the situation of women's vulnerability in household water management in the urban environment of North Jakarta, especially during the COVID-19 pandemic. A quantitative approach with descriptive statistical analysis was used in this study. The result of this study portrays women's vulnerability in household water management during the COVID-19 pandemic in North Jakarta in two categories, 49.26% have a high level of vulnerability, and 50.74% have a low level of vulnerability. The level of exposure, sensitivity, and response capacity assessed the vulnerability components. This study is expected to be a reference for sustainable water management, considering gender roles and conditions in urban environments, especially during disasters.
Floods are natural disasters that have harmed populations in several places in the world. Flooding in urban areas can be caused by coastal floods or river floods. One of the flood-prone areas in Lombok is the Jangkok River, the largest rivers that cross the city of Mataram. Floods have consequences that impact the social and economic activities. Direct impacts of flooding can include damage to property and infrastructure, especially in the settlement area. The purposes of this research are to analyze the flood-prone areas and to build a flood modeling of the Jangkok River. The data used for the analysis combined a topographic map scale 1:5.000, DEM LiDAR, land system, and rainfall data from the Tropical Rainfall Measuring Mission. The result shows that along the Jangkok River at a distance of 100 m estimated as the flood-prone areas. River flood modeling shows settlements have very high potential affected by floods caused by overflowing water from the Jangkok River. Modeling of flood inundation for the return period of 10 years, 50 years, and 100 years shows that the area of inundated settlements periodically expands the flooded area of 70.95 ha, 97.17 ha, and 108.41 ha. This study is expected to be an input to improve the preparation of disaster mitigation-based spatial planning in many coastal cities in Indonesia.
Every year, electricity demand is always increasing, especially in Indonesia where the deficiency of electrical power plants still becomes an issue. Currently, it is necessary to find other alternative sources of renewable fuels that can be used as power plants. One of the solutions is through the development of Micro Hydro Power Plant. Furthermore, social feasibility related to the ability and willingness of the local community is important to be carried out to develop and manage the micro-hydroelectricity sustainably. This study used quantitative data collection techniques through surveys by questionnaires in Paweden Village, Banjarnegara, Central Java. Community capacity analysis is carried out through 3 indicators, such as human capital, organizational resources, and social capital. Spatial analysis is also conducted to find out the affordability of Micro Hydro Power Plant access to the local community. The results showed that the Micro Hydro Power Plant is sufficient to cover 95.87% of the entire Paweden Village area. Related to the electricity needs in Paweden Village, the electricity supply is still insufficient based on the local community opinion. Based on the survey, although the quality of human resources is still limited, the willingness of the community to participate in the development and management of the Micro Hydro Power Plant is considerably high.
