Abstract

Abstract Lake Laut MatiTasi Ana is located in Daeurendale Village, Landuleko Sub-District of Rote Ndao Regency East Nusa Tenggara Province. The conditions and characteristics of water habitat of this Lake greatly affect the diversity of existing biota. Insofar, data and information about the diversity of macrozoobenthos and nekton in this lake arestill are not available. This study aims to identify the diversity of macrozoobenthos and nekton that exist in the lake as well as their habitat condition parameters. The samples of data were collected from four predetermined stations of coordinate points (1.Oemasapoka, 2.Olokama, 3.Kaluoen, 4. Lolokaslain) by using cruise method. The study found that in this lake there exist eight species of macrozoobenthos which include Parathelphusaconvexa, Melanoidesturricula, M. tuberculata, M. maculata, Neritaundata, Mytilusedulis, Acar squamosa, Cerastodermaglaucum. Most of those macrozoobenthos belong to Gastropod class. In addition, there are four species of nekton namely Oreochormis niloticus, O. mossambicus, Paracheirodon simulans, Channa sp. All of these nektons are found only in station 1 (Oemasapoka). It is conceivable asthe watersalinity of this station is 30 0/00 and the pH level is 9.29. Such condition allows the existence of the nektons.

Abstract

Investors need to invest wisely because the Covid 19 pandemic has gone global, so that the stock exchange has also begun to waver. Therefore, several methods are needed to determine investment decisions. This study uses the CAPM (Capital Asset Pricing Model) method and classifies and evaluates LQ 45 index companies based on the level of undervalued and overvalued. This type of quantitative descriptive research is the type of research applied in this research. In this study using saturated samples. Data processing was done using Microsoft Excel application program. The results of the study by comparing the beta value with the expected return have an inversely proportional relationship. from the 45 companies, there are 20 Undervalued companies and 25 Overvalued companies.

Abstract

Drainage in peatland caused reducing water storage and subsidence. Groundwaterlevel fluctuations are a major role in the water balance that occurs in peatlands. Theresearch was conducted in a specific area of agricultural peatland. The location inSub-Peatland Hydrological Unit (Sub- PHU) 5 and 6 Kahayan Sebangau, CentralKalimantan Province, Indonesia. Modeling for groundwater table was applied usingFreewat / Modflow software with input rainfall probability 80% (R80), infiltration,and evapotranspiration data analysis. Groundwater table should not be less thanminus 0.4 meters based on the Indonesian Ministry of Environment and Forestry(Menlhk). The deficit means the groundwater level below -0.4 m and surplus uponthe criteria. Land modeling is simulated with an area of 300 x 1000 meters. Thecalibration in the model was found conductivity values, 50 m / day or 5.78 x 10-4 m /s with the best value with the largest NSE and Correlation. The modeling showedthat the deficit occurred in seven months. The groundwater management is how tokeep the water level upon -0.4 m with the planning of canal blocking height. Thescenarios are 0.2 m. 0.3 m, 0.4m, and 0.5 m upon the base flow of the canal. Thebest scenario was chosen 0.5m according to the simulation which has the waterlevel upon -0.4 m.

Abstract

Dysmenorrhea is the pain experienced during menstruation that causes women to experience varying degrees of cramps. It presents as discomfort, while others suffer pain that can stop daily activities for some women. Therefore, to reduce the use of drugs, herbal methods are used, boiled water for the wood secang, so that side effects can minimize for the body. This research aims to analyze the reduction of Visual Descriptor Scale (VDS) of adolescence with dysmenorrhea in Makassar. This research lasted for one year with several stages, including the first stage; identify research samples based on criteria. The second stage, making informed consent and choice of respondents. The third stage, using a Quasi-Experimental design with a pretest and post-test approach in one treatment group, namely adolescents with dysmenorrhea, measured VDS before giving the boiled water for secang wood and after giving it. The fifth stage, assessing the decrease of VDS before and after treatment. This study indicated that the average intensity of the respondents' menstrual pain before giving the boiled water of secang wood was 4.5, where the lowest menstrual pain intensity was two. The highest was 8, while after giving secang wood boiled water was 3.0, where the pain intensity was the lowest menstrual period was 0, and the highest was 6. The Paired T-Test results obtained a p-value of 0.000 <0.05 so that the boiled water of secang wood affects reducing pain intensity in young females.
