In the future, climate change, especially temperature increase that occurs throughout the world is expected to pose a high risk both physic and social. As one of the coastal areas in Indonesia that has a high level of vulnerability to sea level rise, currently Semarang has experienced to inundation. Some areas in North Semarang such as Bandar Harjo and Tugu has been inundated and abandoned by its residents for quite a long time. The unavailability of information on disaster hazard prediction maps for future conditions is the background of the need for making accurate and actual flood hazard maps to minimize the impact of disasters. The combination between Geographical Information System (GIS) and Analytical Hierarchy Process (AHP) has been used to analyze and to determine the weight and score the risk map of Semarang City. As a result, 37% (141.403km2) areas of Semarang City are vulnerable to flood. This result is divided into 19 % high vulnerable, 13% moderate and 5% are low. By this, the flood risk map of Semarang City can be used by stakeholders and government to make a safe and resilience city planning.

Semarang is one of the cities with many threats of natural disasters that have an impact on human life, can bring harm and can also be good. One of the natural disasters that often occurs and has a direct impact on human life is flood disaster. The purpose of this study was to determine the extent of flooding from 2020-2021 in Semarang City and changes in the socioeconomic conditions of people affected by floods and people affected by Covid-19. This study used several data collection methods including a survey of topographical conditions and also interviewing respondents related to socio-economic conditions. The research was conducted in the city of Semarang as a potential flood area. The sample was selected using purposive sampling, the criteria for the age of 18-39 years or commonly referred to as the millennial generation. Field observations were carried out with guided questionnaires to collect data on the role of the government, community, private sector and non-governmental organizations in flood management. Data were analyzed based on demographics, areas, and understanding of flood disasters. After that the data is processed and processed into spatial data so that it can be in the form of vulnerability maps and flood disaster preparedness levels in the city of Semarang. Results of the study it can be concluded that the area of flooding in the city of Semarang in 2020-2021 is 24,443 hectares and the category of disaster risk is classified as having a high impact on the socio-economic conditions of the community.

This study was conducted to investigate poultry farming and the impact of insurgency on poultry production in Maiduguri Metropolitan Council, Borno State, Nigeria. A total of 170 poultry farmers were randomly selected from the areas and a structured questionnaire was administered to each farmer through scheduled interviews. The results of this study showed that a larger percentage of poultry farmers were male (59.4%) and the majority of the respondents were educated (72.9%). A significant proportion of the respondents (p=0.037) were full-time farmers (38.8%), and the percentage of married people was 58.8%. The majority of respondents (57.1%) had between 0 and 5 years of experience in poultry farming with majority of farmers preferring the keeping of broiler chickens (52.9%). In addition, deep litter rearing (72.4%) was the most common production system. Before the insurgency, most of the flock size was in the range of 100-200 birds but during the Boko Haram insurgency they ranged from 50-59 birds signifying a decrease in the production output attributed in parts to disruption of economic activities due to the unrest. In conclusion, due to insurgency, in Maiduguri, poultry farming has been negatively affected resulting in decline in production. We therefore recommendthat the government, non-governmental organisations and wealthy individuals support farmers with financial resources to revive the poultry industry in the study area

High School State 12 Semarang is in Plalangan Village which is one of the villages with a high vulnerability to landslides in Gunungpati District, Semarang City. Students need knowledge about prevention and preparedness, in order to reduce the impact of landslides. This study aims to determine the learning process of landslide risk reduction, find out student responses to landslide simulations, and find out the difference between learning outcomes for students who get learning using disaster simulation with students who get learning without using simulation. This study uses a quasi-experimental research design, using quantitative analysis in the form of percentage calculations and analysis of independent test samples t-test. The results of the t-test showed that there were differences in student learning outcomes between students who received learning using disaster simulation with students who received learning without using disaster simulation. Thus, learning using disaster simulation is better than learning by not using disaster simulation, meaning that disaster simulation can be used as an alternative learning method in learning to reduce landslide risk in the city of Semarang.
