Indonesia is an archipelago with a tropical climate with very high rainfall. In the rainy season floods occur which cause losses, namely loss of life and property. This condition is a routine disaster that always threatens people's lives. Therefore, research needs to be done to identify flood-prone areas and flood-causing factors in the Maros River Basin. The method used to determine flood-prone areas is used by a combination of remote sensing, terrestrial, secondary data and interviews using the criteria of Sutikno et al (1995) with development. The variables used topography (flat and sloping), soil texture, drainage, inundation time and flood return period. The analysis shows that in the Maros watershed there are 3 classes that are prone to flooding namely not prone, prone and very prone. Most are vulnerable because more than 50 percent of the area is at a vulnerable and very vulnerable level. The class is very prone to spread from downstream to the middle of the watershed, covering the southern sub-districts of Maros Baru, Marusu, Turikale, southern Bantimurung, western Simbang, northern Mandai and northern Tanralili. The contributing factors are high rainfall, flat and sloping topography, fine soil texture in the downstream river, poor drainage due to poor waste management, land use dominated by ponds and paddy fields and high flood return periods.
This study is aimed at building and analysing a SIRS model and also simulating the model to predict the number of dengue fever cases. Methods applied for this model are building the SIRS model by modifying the SIR model, analysing the SIRS model using the Lyapunov function to prove three theorems (the existence, the free disease, and the endemic status of dengue fever), and simulating the SIRS model using the number of dengue case data in South Sulawesi by Maple. The results obtained are the SIRS model of dengue fever transmission, stability analysis, global stability, and the value of the basic reproduction number R 0 . The simulation done for the dengue fever case in South Sulawesi found the basic reproduction number R 0 = 26.47609 > 1 ; it means that South Sulawesi is in the endemic stage of transmission for dengue fever disease. Simulation of the SIRS model for dengue fever can predict the number of dengue cases in South Sulawesi that could be a recommendation for the government in an effort to prevent the number of dengue fever cases.
This study aims to determine the quality of the Dayak cultural tourism area in the village of Pampang village in East Kalimantan and determine the contribution of the Dayak cultural tourism area to the level of income of the Dayak tribe community in the village of Pampang, East Kalimantan. The population in this study were people who work in the Dayak cultural tourism area in the village of Pampang, East Kalimantan as many as 30 people. The number of samples taken was 30 people using total sampling. Retrieval of data in this study using observation techniques, questionnaires, and documentation. Then analyzed using qualitative and quantitative analysis techniques (mix methods). Research data is displayed in the form of frequency and percentage tables. The results showed that the quality of the Dayak cultural tourism area in the village of Pampang was included in the "good" category of 61.1%. With the contribution of the Dayak Kenyah community in the village of Pampang to the level of income, the highest number of contributions obtained by respondents was 85.71% and the lowest number of contributions obtained by respondents was 15.62%.
This research is included in a qualitative research that aims to determine public perceptions about the structure of macrocosm and symbol of the construction of a Bugis traditional house in Manurungnge village Tanete Riattang sub-district based on cultural geography. Macrocosm is an understanding of Bugis Bone society's trust in the universe that implemented into a form of dwelling. This understanding has been around for decades. After conducting research, it can be concluded that with the times, the understanding of this macrocosm has begun to fade among the people, the structure of the macrocosm is very closely related to the symbol of Bugis traditional house construction, because every time when building a traditional house, the public always includes the symbol of construction on the Bugis traditional house
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
