Floods are recurring disasters in urban areas, particularly in flood-prone regions, such as Makassar City, Indonesia. The preparation of residents for such events is crucial for reducing risks and enhancing resilience. This study aims to analyze the relationship between Quality of Life (QoL), as measured by the World Health Organization Quality of Life-BREF (WHOQOL-BREF), and disaster preparedness in flood-prone areas of Makassar City. A combination of conventional statistical methods and Structural Equation Modeling- Partial Least Squares (SEM-PLS) was used to analyze the data collected from 409 respondents across four sub-districts: Biringkanaya, Tamalanrea, Panakkukang, and Manggala. The findings indicate that a higher QoL correlates with improved disaster preparedness, suggesting that efforts to enhance residents' well-being can positively influence their readiness for floods. Based on these results, this study proposes integrating QoL factors into disaster preparedness programs to increase community resilience.

In order to support Indonesian Government priority sector to build toll maritime in conjunction to connect “nusantara” as an archipelago country, and also to develop the frontier area of Indonesia, the existence of a port should get more in attention as the gate of Indonesia. A port has significant role in changing of transport mode and at the end as catalyst of economic growth. An important thing from pre-feasibility studies is the priority factor will clearly shown wheather it is good or fair. As a supporting to service passenger moving, container, general cargo and also bulk, a port is necessary to have an excellent design and planning. A pre-feasibility study is required to obtain a scientific basis based on value of interest and the necessity of the region. A pre-feasibility study in this paper aims to identify potential support of the region and giving priority location of development of new port in Minahasa Utara regarding to spatial, government issues, transportation aspect, regional economics, environmental aspect and technical aspect consideration. Experimental Method used are qualitative and quantitative, going through to the data obtained and supported by interview on the spot as well as questionnaire surveys. Result of this paper showing that there are 5 locations suitable with the requirements. Based on the level of priority, high (Kema, Likupang), moderate (Linuhu, Kahuku) and low (Gangga 1).

The back–arc thrust region in Eastern Java to Flores is significantly influenced by the arc–continent collision between the Australian Plate and the Eastern Sunda Arc, leading to a tectonic regime characterized by high seismic and volcanic hazards. This area has experienced several major earthquakes. However, back–arc thrust in Eastern Java remains absent from significant shallow earthquakes, which might indicate intense deformation. We conducted an analysis using recent and dense Global Navigation Satellite System (GNSS) observations from both continuous and campaign stations to develop a strain rate model and explore the detailed crustal behavior and strain accumulation within the Eastern Java back–arc thrust system. Our findings revealed varying values of compression and extension throughout the region, with compression values ranging from −2.24 to 0.086 μstrain/year. Additionally, we observed that the maximum shear strain rate and dilatation strain rate were within the ranges of 0.0013 to 1.12 μstrain/year and −2.24 to 0.698 μstrain/year, respectively. These findings could facilitate more informed strategies and improve preparedness for future seismic events.

The objective of study is to reduce surface water runoff in low-lying areas that potentially occurred flooding. The concept of environmentally friendly drainage is the right choice to be applied in reducing the potential for flooding and sediment buildup, especially in areas with small water absorption. The quantitative method used to analyze hydrological and flood discharge then evaluated canal capacity in urban area. Rainfall data and population development for 10 years are used to determine the planned discharge with a certain return period according to actual conditions. The result show that from the 4 types of primary canals, an average of 1.03 m3/sec can be obtained. while the evaluation results for the secondary channel obtained 7 channels with a reduced average inundation discharge of 1.97 m3/s. It can be said that the application of infiltration wells is quite effective to be used as an alternative solution in reducing inundation of urban area.
