Abstract

Amarilis waterfall is in the area of Forest Park (Tahura) Nipa-Nipa mountains in addition to serve as a natural tourist spot as well as upstream sources of clean water by people around the flow of waterfalls lasting ± 30 years. The problem is that in the last two years water entering the community began to blur during the rainy season and reduced, none other than the problem of discharge and many other tourism potentials to be observed by visitors. So the researchers analyzed the flow of waterfall flow Amarilis and identify the potential tourist attraction waterfalls. After measuring the flow of Amarilis waterfall flow of 0.315 m3 / sec (instantaneous measurement). Waterfalls in addition to the potential of natural tourism there is another potential that is; peak viktor camp area, flora there are various types of plants, fauna there are various types of animals and natural panorama that has the appeal of the pengujung and observe the expanse of Kendari and Kendari Bay.

Abstract

The problem in this research is how the magnetic susceptibility of the soil and the rate of evapotranspiration in Ranooha Village, Ranomeeto District, Konawe Selatan District. Soil magnetic susceptibility was measured using Bartington Susceptibility MS2B meter while evapotranspiration rate was measured using Lycimeter. Soil magnetic susceptibility analyzed consisted of three sampling points, each consisting of vegetation (grass) and non-vegetation (without grass) sites, with the same depth variations namely 0 cm, 10 cm, 20 cm, 30 cm, 40 cm and 50 cm. Each sample is coded V00, V10, V20, V30, V40, V50 for sampling at vegetation (grass) sites, and NV00, NV10, NV20, NV30, NV40, and NV50 for sampling at non-vegetation (without grass) sites. The measurement results show that variations in values of χLF range from a minimum value of 0.8 x 10-8 m3/ kg toa maximum value of 3.8 x 10-8 m3/ kg at point 1, minimum value of 0.8 x 10-8 m3/ kg up to a maximum value of 3.9 x 10-8 m3/ kg at point 2, and a minimum value of 0.9 x 10-8 m3/ kg up to a maximum value of 2.6 x 10-8 m3/ kg at point 3 for vegetation (grass). While variations in values of χLF rangefrom a minimum value of 1.7 x 10-8 m3/ kg to a maximum value of 2.4 x 10-8 m3/ kg at point 1, a minimum value of 1.6 x 10-8 m3/ kg up to a maximum value of 2.9 x 10-8 m3/ kg at point 2, and a minimum value of 1.6 x 10-8 m3/ kg up to a maximum value of 2.9 x 10-8 m3/ kg at point 3 for non vegetation (without grass). While the maximum rate of evapotranspiration occurs in November for 2018 which is 5.3 mm / day, while the maximum rate of evapotranspiration in 2019 also occurs in November which is 6.1 mm / day for vegetation (grass) sites. While the maximum rate of evapotranspiration occurs in October for 2018 which is 4.3 mm / day, while the maximum rate of evapotranspiration in 2019 occurs in November which is 5.7 mm / day for non-vegetation (without grass)  sites

Abstract

The aim of study is to investigate the impact whatsapp-blended learning implementation of SMKN 2 Kendari student’s understanding of electricity learning. The study is quantitative research with pre-experimental way while using one group pretest-posttest design of research. Moreover, a research sample is taken by the method of probability sampling which is kind of simple random sampling. A technique of data collecting uses to test and non-test (questioner). A technique of data analysis uses descriptive statistic and inferential statistic. The results of this study show that the average value of student’s abilities to understand the physic concept on pre-test which is representatively 43.72, while in the post-test it is 88.00 while in the post-test it is 88.00 with an average n-gain of 0.78. The study shows that blended learning application generally takes a great response of students, which stood on 64.48% of the average scores.
