Culture and traditions are formed due to several factors, one of which is geographical factors. Along with the development of the times, culture and customs have an essential role in creating the spatial structure. The spatial frame formed in each region will vary according to the ordinary conditions of the community in carrying out life. A spatial pattern influenced by geographical factors is the Sa'o Atalaki house, located in the Wolotopo traditional village, Ende Regency, East Nusa Tenggara. This study examines the spatial pattern of the Sa'o Atalaki traditional house and its relationship to geographic spatial patterns. This research uses a descriptive analysis method with literature study and direct observation. The study results are the spatial pattern of the Sa'o Atalaki traditional house consisting of several parts that function as a burial place, a deliberation room, and a traditional offering room for ancestors. Meanwhile, spatial planning in geography is divided into no parts, namely spatial, spatial ecology, and spatial complex. The spatial arrangement of traditional houses and geography is made according to the needs of each spatial function, as well as social and environmental impacts.

This type of research is descriptive and quantitative. The sample in this study was the entire subject population, namely all 61 students consisting of two classes. The data collection technique was carried out by distributing a questionnaire (questionnaire) to respondents, which contained questions about the open personality of students and the geography learning experienced so far in the learning process. The descriptive percentage data analysis technique is intended to determine the status of variables, namely, to describe openness personality in geography learning. This study found that learning geography can put students in contact with their geographical environment to better understand modern processes and problems. The strongest openness personality of the MAN I Medan students is curiosity, while the lowest openness personality is smart and thinking. Curiosity is an action that always seeks to know deeper or wider than something learned, seen, and heard. Therefore, it is necessary to provide freedom by explaining the learning encyclopedia to develop and accommodate students' curiosity. This happens due to differences in all student’s abilities and personalities. Personality and ability are dimensions of individual differences in the tendency to exhibit consistent patterns of thinking, feeling, and acting. The nature of the personality focuses on identifying, describing, and measuring individual differences and is also a behavioral and mental mark typical of individuals who refer to differences through feelings, emotions, actions, motivations, and behaviors.Keywords: Geography, Openness Personality, Students","PeriodicalId":31787,"journal":{"name":"Jurnal Geografi","volume":"70 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82135059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rainfall observation data in some areas are incomplete, so alternative data are needed for rainfall estimation for those areas, such as satellite data. However, the satellite data does not necessarily match the conditions in the field, so validation is needed. In this study, satellite data were validated with available observational data in the area, so the results can be used as a reference when field data is unavailable. The data used are GSMaP_GNRT6 and observation data from 5 rainfall observation posts: Beutong, Cut Nyak Dien Meteorological Station, Darul Makmur, PT. Socfindo and Pulo Ie for the period 2010-2019. The satellite and the observation data were correlated with the Pearson method to see the relationship between the two data. The difference between each satellite data and observations at the same time and place is calculated using the formulas Mean Error (ME), Root Mean Square Error (RMSE) and Mean Absolute Error (MAE). Furthermore, a case study of fire incidents and satellite hotspot data at several locations was also observed simultaneously. In addition, the validated rainfall data were also used to calculate the Standardized Precipitation Index (SPI) value. The result shows the validation of rainfall data with GSMaP_GNRT6 satellite data has a moderate correlation with the MAE value ranging from 101.3 to 195.12 from the five rainfall observation posts. The results also show that a 10-day base of rainfall before the occurrence of the wildfires was in a low category (86%).
