The use of plants as traditional medicine has been known since long time ago by people in Lipu. This process has been inherited from one to next generation, nevertheless. nowdays, it has started to be extincted. So, it should be better to indentify the species of plant used as traditional medicine by people in Lipu. The research aims to investigate thekinds of plant which uses as traditional medicine. The part of plant used and how to process and the adventage of the plant. The research used explorative survey method. The result of the research there are 54 species from 31 family of plants used as traditional medicine by the people. The parts used of plant are leaf, stem/bark, root, flower, fruit, seed, tuber,rhizome and sap. The processing of the plants by refine, boil, squeeze, parch, pour boiling water, rasp and without processing. And the ability of the plants are can treat kinds of disease.

This study aimed to determine the effect of planting media and shoot pruning on the vegetative growth of the tapak dara (Catharanthus roseus (L.) G. Don) plant. The research method was factorial completely randomized design (CRD) with a combination of planting media and shoot pruning. The treatments were ultisol soil media (M0), a mixture of husk charcoal in a ratio of 1:1 (M1) and 1:2 (M2) with a pruning frequency of no shoot pruning (P0), 1 time pruning (P2) and 2 shoots pruning (P2), so that 9 treatment combinations were obtained, namely M0P0, M0P1, M0P2, M1P0, M1P1, M1P2, M2P0, M2P1 and M2P2, each treatment consisted of 3 replications so that the all sample of media used in this study was 27 polybags. Parameters observed in this study were vegetative growth including plant height (cm), number of branches, number of leaves (strands). The results showed that the planting medium and shoot pruning had a significant effect on the vegetative growth of the tapak dara (Catharanthus roseus (L) G. Don) plant which included plant height, number of branches and number of leaves, where the best plant height measurement was the M2P0 treatment with height the plant reaches 23.5 cm. The highest number of branches was produced in the M2P2 treatment with an average number of branches, which was 7.3. The highest number of leaves was in the M1P1 treatment with the number of leaves reaching 40 strands.

Research has been carried out in the coastal area of Moramo District, South Konawe Regency. This study aims to determine the value of the distribution of sediment layer thickness. Data collection was carried out using a TDL-303S seismometer at 15 measurement points. Microtremor data were analyzed using the HVSR method (Horizontal To Vertical Spectral Ratio) use software geopsy 3.4.2 to obtain the dominant frequency value (f0) which then determines the value of the wave velocity shear (VS30) to obtain the value of the thickness of the sediment layer (h). The results of data analysis obtained the dominant frequency value (f0) obtained ranged from 1.025 Hz to 14.297 Hz and the wave speed values shear (VS30) obtained from website www.USGS.gov with a range of values ranging from 234.43 m/s to 422.33 m/s. Based on the data obtained, the value of the distribution of sediment layer thickness (h) will be determined. The thickness of the sediment layer in the study area ranged from 6.596 meters to 66.124 meters.

The essential analyses in the magnetic method are fundamental approaches of geophysical studies that should be commonly applied for interpreting the magnetic data. In this study, the essential analyses of the magnetic method incorporated several fundamental techniques such as analytic signal processing, upward continuation technique, horizontal gradient method (HGM), tilt angle derivative (TDR), and Euler deconvolution. These techniques were successfully applied to process the field data acquired from the Lainea geothermal site, South Konawe District, Southeast Sulawesi Province, Indonesia. The results of the magnetic data processing were then analyzed to characterize the anomaly sources. This analysis is applied to the total magnetic intensity (TMI). Based on the application of all essential stages in processing and analysis of magnetic data, it was found that signal analysis and Euler deconvolution were effective and efficient in analyzing the magnetic anomaly source. Furthermore, from the TMI map it can be verified that a positive anomaly trend corresponding to the main fault and formation distribution. The HGM implementation can accurately detect the edge boundary of the body anomaly in the form of the altered rock. Here, there are several magnetic lineation paths trending in the north-south (N-S), northeast-southwest (NE-SW), and northwest-southeast (NW-SE) directions. The combined results of TDR and Euler deconvolution can completely show the detection of edge and depth of the anomaly. In particular, the altered rock zones can be specifically found at Boroboro fault, Windo fault, Kaindi fault, Laindi fault, and Lainea fault. A contact anomaly indicating rock intrusion was detected at a depth of 1300–1500 m, which may be associated with the development of altered rock zones.
