Abstract

The use of land is a part of the fulfillment of human needs. The establishment of a large-scale infrastructure project often triggers an increase in land cover around its infrastructure project. Most of the increase in built up land tends to occur in areas that are traversed by or located near main accessibility routes such as toll roads. Although the construction of toll roads can improve accessibility between regions, land is a limited resource. So that it becomes the basis for researchers to identify the changes in land use in regencies and cities on the island of Sumatra that are crossed by toll roads that have been operating. The goal of land use change analysis is to give a description or explanation, predict, look at the effects, and make a decision (prescription). This research was conducted by identifying the changes in the existing land cover and predicting the land cover using cellular automata. Cellular automata have proven to be a method that is suitable for predicting the dynamics of land use through spatial simulation. The results show that there was an increase in the amount of land built from early 2017 to 2030. The covered land is developed around the toll gate after it is actively operated. In all provinces studied, deviation discrepancies were found in the conservation and cultivation areas. Deviations that occur in conservation areas need to be considered as there should be no land built in these areas, which means that there are cultivation activities in the conservation areas.

Abstract

Urban water management efforts are essential in encouraging the fulfillment of the SDGs targets. One action that can be done is to approach the calculation of the actual water consumption value. This research conducted a survey of domestic water consumption in Bandar Lampung City to obtain comprehensive information. Bandar Lampung City was chosen because it is one of the cities on the island of Sumatra with a high economic growth rate. Lampung Province is the top 3 province in Sumatera Island with the higher Gross Domestic Product Growth on 2022, with Bandar Lampung as its capital city. Furthermore, water consumption patterns were analyzed for various activities, socio demographic conditions, and the community's economy. The results showed that of the 404 samples, the average water usage was 195.08 liters/person/day, with the dominant activities in use including bathing (66.84 liters/person/day), flushing the toilet (35.71 liters/person) / day), and ablution (29.74 liters/person/day). Furthermore, the variable number of family members in one house and income level have significant different on total domestic water consumption. The results obtained in this study are expected to assist in making decisions regarding urban water management plans.
