Suitable small farm reservoir development planning for drought disaster risk management of agricultural land using remote sensing and GIS

Abstract

Water is the resource and determinant factor that determines the performance of the agricultural sector, although the role is very strategic, the water management is still far from expected so that the water that should be a farmer's turn turned into a cause of disaster for farmers. Small farm reservoir is built to accommodate excess rainwater during the rainy season. The water collected is then used as a source of supplementary irrigation for the cultivation of high-value economic commodities in the dry season. This research aims to survey, inventory, and study the potential of small farm reservoir development, and to plan potential site locations to be developed into small farm reservoir based on the results of analysis of physical and socio-economic data and drought potential using advanced remote sensing technology in Jombang Regency. Research planning of small farm reservoir location in Jombang Regency is designed in four stages of activity that is data gathering, mapping, and compilation of database, analysis, planning of location, and recommendation of the small farm reservoir location. The results of this research state that the appropriate area built small farm reservoir based on the parameters used are Ngoro, Mojoagung, Kesamben, and Kabuh village.

Waters Quality Assessment on Physical-Chemical Parameters Using Remote Sensing Technologies: Criteria for Total Suspended Solids and Waters Transparency

“…Waters transparency can be observed visually using a Secchi disk (Olmanson et Remote sensing is the process of gathering information without direct contact with the object under research carried out using an airplane or satellite (Danoedoro, 2012;. The development of remote sensing is increasingly rapid making this technology more effectively used for ecosystems with wide coverage areas (Wicaksono et al 2016; Danoedoro, 2012;Anurogo et al, 2019). Remote sensing is able to provide information and synopsis description because it plays an important role to map, monitor, and evaluate coastal and marine areas at the same time (Yanti et al 2016;Lubis et al, 2017).…”
