Abstract

The function change of land in upstream areas of subwatershed Cikapundung is very difficult to control. Most of the land has been turned into residential areas and vegetable crops. Land is currently a source of life, so it is exploited to get maximum results and income. If it is not managed properly, the land will be degraded and eventually become critical. In order for the land to be sustainable it needs an environmentally friendly farming farming system for vegetable conservation The results showed that there were two technologies for specific vegetable crop conservation systems in upstream areas of subwatershed Cikapungdung that were environmentally friendly, namely (1) Conservation farming system of bench terrace conservation, beds cutting slopes, using manure + lime, plastic mulch installed, planting system of intercropping/ overlapping rotating vegetables on land with slope of 15-25%. The conservation farming system is able to control erosion from 69.93 to 7.18 t/ha/year or by 89.73% and (2) a farming system for conservation of ridge terraces, beds cutting slopes, using manure + lime, installed plastic mulch, system for planting intercropping/overlapping vegetables on land with a slope of 8-15%. The conservation farming system is able to reduce erosion from 37.41 to 15.27 t/ha / year or 59.18%. The two conservative farming systems above are financially profitable as indicated by the value of BC Ratio> 1, NVP> 0, and IRR> The prevailing Social Discount Rate or Bank interest, which is around 12% indicated by the value of BC Ratio> 1, NVP > 0, and IRR> Current Social Discount Rate or Bank interest, which is around 12%.

Abstract

Pariaman city is one of the areas most severely affected by natural disasters that have the potential for tsunamis. The impact of the earthquake potential tsunami seen in fatalities and damage to infrastructure, both residents' homes and other public facilities. The impact also caused the community to lose their livelihood. Most of the people of Nagari Gunung Padang have livelihoods as farmers, after the earthquake disaster has the potential of a tsunami, many people lost their land and gardens because of the cliff ruins and buried by landslides that caused the land cannot be recycled. By taking into account all the physical, social, and economic aspects, this is the reason for the researchers' interest to conduct research related to the direction of Natural Disaster Mitigation Policy based on Environmental Physical Conditions and Socio-Economic Characteristics of Coastal Area Communities in Pariaman city. With Mixed Method methods, such as simultaneous and sequential data collection. Then descriptive physical environmental conditions and socio-economic characteristics, and Focus Group Discussion (FGD) in policy direction. The results of this study in the form of an explanation of the physical, social and economic Pariaman city, as well as the policies needed in disaster mitigation in Pariaman city

Abstract

The purpose of this research is to analyze the spread of COVID-19 on the earth's surface. The method used is a spatial method with the Geographic Information System (GIS) analysis technique. The results of this study explain that the spread of COVID-19 very much occurs in the region of moderate latitude. Besides, tropical climate conditions can also make the virus more quickly become unstable. The Coronavirus spreads faster in countries with high latitudes and humid climates. The spread and concentration of the COVID-19 virus increasingly to the poles are easier to develop, current conditions at high latitudes or poles are not significantly affected due to a small population concentration and population activity, so the virus cannot spread, because the body's virus does not find a host (human) to live and develop.
