The history of floods that have occurred in Baubau City from 2009 to 2018 occurred as many as 20 cases, submerging population buildings with a total of 1,206 units. To reduce the impacts that have previously occurred, this study aims to determine the potential flood areas in the Baubau watershed with a return period of 5 to 100 years. The first thing to do is to know the design flood discharge using 10 years of rainfall data analyzed by the Nakayasu Synthetic Unit Hydrograph method. From the results of the field survey data on river hydrological characteristics and watershed morphometric parameters were obtained then analyzed with a hydraulic model using HEC-RAS 5.0.7 software then exported to HEC-GeoRAS is a tool of ArcGis version 10.5. Based on the results of the hydrological model integrated into the hydraulic model in the findings of this study, an estimate of physical, social and economic losses is obtained as well as maps of spatial-based flood potential areas that occur in 3 sub-districts namely Murhum sub-district, Batupoaro sub-district and Wolio sub-district scattered in 7 urban villages through which the Baubau river flows with a high risk class status level.

Landslide is a movement of soil with slope direction and moves it on a slide. This study aimed to predict the landslide susceptibility map by using a frequency ratio. It used seven causative factors, such as slope, curvature, land use, lithology, distance to a river, distance to lineament, and rainfall. The result showed the AUC of success rate and predicted rate produced high accuracy with 0.907 and 0.904, respectively. According to the frequency ratio, the slope was the most influential than the other causative factors with 7.15. The landslide susceptibility divided into five classes, i.e. very low, low, moderate, high, and very high. Landslide susceptibility with very high and high was 19%. Moreover, classes susceptibility of very low, low, and moderate were 71%. The presentation of very high and high susceptibility is low, but it was located on an upper stream, and it will be a danger if to the downstream.

The study aims to develop and apply land use change (LUC) performance on landslide susceptibility map using frequency ratio (FR), and Logistic regression (LR) method in a geographic information system. In the study area, Upper Ujung-loe Watersheds area of Indonesia, landslides were detected using field survey and air photography from time series data image of Google Earth Pro from 2012 to 2016 and LUC from 2004 to 2011. Landslide susceptibility map (LSM) was constructed using FR and LR with nine causative factors. The result indicated that LUC affect the production of LSM. Validation of landslide susceptibility was carried out in this study at both with and without LUC causative factors. First, performances of each landslide model were tested using AUC curve for success and predictive rate. The highest value of predictive rate at with LUC in both FR and LR method were 83.4 % and 85.2 %, respectively. In the second stage, the ratio of landslides falling on high to a very high class of susceptibility was obtained, which indicates the level of accuracy of the method.LR method with LUC had the highest accuracy of 80.24 %. Taken together, the results suggested that changing the vegetation to another landscape causes slopes unstable and increases probability to landslide occurrence.

This study aims to build a landslide susceptibility map (LSM) by using certainty factor (CF) models for mitigation of landslide hazards and mitigation for people who live near to the forest. In the study area, the mountainous area of the Ujung-loe watersheds of South Sulawesi, Indonesia, information on landslides were derived from aerial photography using time series data images from Google Earth Pro© from 2012 to 2016 and field surveys. The LSM was built by using a CF model with eleven causative factors. The results indicated that the causative factor with the highest impact on the probability of landslide occurrence is the class of change from dense vegetation to sparse vegetation (4-1), with CF value 0.95. The CF method proved to be an excellent method for producing a landslide susceptibility map for mitigation with an area under curve (AUC) success rate of 0.831, and AUC predictive rate 0.830 and 85.28% of landslides validation fell into the high to very high class. In conclusion, correlations between landslide occurrence with causative factors shows an overall highest LUC causative factor related to the class of change from dense vegetation to sparse vegetation, resulting in the highest probability of landslide occurrence. Thus, forest areas uses at these locations should prioritize maintaining dense vegetation and involving the community in protection measures to reduce the occurrence of landslide risk. LSM models that apply certainty factors can serve as guidelines for mitigation of people living in this area to pay attention to landslide hazards with high and very high landslide vulnerability and to be careful to avoid productive activities at those locations.

RTH in urban areas has undergone many changes into built-up land so that it has changed its function into settlements, hotels, restaurants and others due to the very high growth of urban activities in Makassar City. Cemeteries have the main function as a place of public service for the burial of bodies. Cemeteries can also function as green open spaces to add to the beauty of the city and can function as water catchment areas, protectors, ecosystem supporters, and unifying urban spaces. The research aims to determine the design of the appropriate burial area model that functions as green open space and determine the potential of green open space that can be maximized from the Makassar City cemetery area. Research using survey techniques and descriptive analysis of 7 TPUs in Makassar City, was carried out from July to August 2021. The results show that dense cemeteries with high land cover have reduced the function of TPU as City Green Open Space. The design of the TPU in the context of optimizing the green open space increases the capacity of the tomb and improves environmental functions and religious norms, through the addition of facilities and diversity of vegetation.
