Abstract

In 2020 corn production in TTU Regency experienced a decrease in corn productivity by 21.91 percent from 2019 corn production of 46,621 tons to 36,406, one of which is Central Insana District. This study aims to: (1) Identify the geographical and non-geographical factors that influence the potential for maize crop failure in Insana Tengah Subdistrict, (2) Identify the efforts made by the people of Insana Tengah in dealing with maize crop failure. This research is a quantitative research with descriptive method with variable X in the form of geographical factors namely rainfall, sunshine, slope while variable Y is potential corn crop failure. The study population was 895 farmers with a sample of 90 farmers from 7 villages in Insana Tengah sub-district determined using the Slovin formula with an error rate of 10%. Data sources consisted of primary and secondary data collected by observation, documentation, and questionnaires. The analysis method uses descriptive analysis, multiple correlation, with Microsoft Excel, and SPSS software. The results showed that: (1) Geographical factors in the form of slope have a higher influence than the intensity of rainfall, the intensity of solar irradiation, has an influence of 0.638 while, the intensity of rainfall, the intensity of solar irradiation 0.287 and 0.294. (2) Efforts made by the community are in the form of non-geographical factors, in dealing with pest attacks on corn plants the community does by means of technical culture control, namely by managing planting media, cleaning weeds, and providing fertilizers that are not excessive. Then chemical control is done by using active insecticides. Based on the results of the study, it is concluded that geographical factors in the form of rainfall intensity, sunlight intensity, and slope have an influence on corn crop failure. The influence of geographical factors in the form of rainfall intensity, sunlight intensity, and slope on corn crop failure in Insana Tengah Subdistrict using multiple correlation analysis obtained a result of 0.759 which shows that the factors of rainfall intensity, sunlight intensity, and slope, have an influence of 76% on corn crop failure, while 24% is influenced by other factors.

Abstract

Earth Science System In The Community Learning Model is a model that is oriented towards problems that occur in the earth that can be solved within the scope of the community (society). The purpose of this study was to determine the effect of the Earth Science Community (EarthComm) learning model i n geography subjects on students' spatial thinking skills at SMA Negeri 2 Kota Kupang. The type of research used is quantitative research, the method used is quasi-experimental with the form of research design is Nonequivalent Control Group Design. The population of this study is all students of class XI IPS with sampling techniques using saturated sampling techniques. The results of this study indicate that the average value of the experimental class is higher than the control class. It is known that the average value of the control class is 69.57 and the experimental class is 75.86 so that there is a difference between the two. Based on the results of data analysis of the Independent Sample T-Test test, there is an effect of the Earth Science System in the Community (EarthComm) learning model in geography subjects on students' spatial thinking skills compared to the control class using the conventional model. The EarthComm learning model is recommended to be used as a variation of teacher learning in the application of the learning model. This model can also be develo ped by other researchers by adding moderator variables or other media.
