Abstract

The geoelectric method is a very effective method for subsurface aquifers (water reserves). This method is based on the injection of an electric current from the surface to the earth's body with a certain electrode configuration. The geoelectric method used in this study uses a Schlumberger electrode configuration. Surveys with this method are proven to be able to map the height of the water table at a point in the survey area. In this study, the geoelectric method has been proven to be able to map the potential for water flow discharge in aquifers. From the results of the calculation of the potential for water discharge using the Darcy equation, it is found that the discharge value is around 22.11 liters per second.

Abstract

Gravity is a concept that is considered difficult for students and it is not uncommon for them to experience misconceptions about this concept. This study aims to analyze students' conceptions of the concept of gravity. The research was conducted at SMPN 1 Aikmel, West Nusa Tenggara, Indonesia. The sample consisted of 28 Class VIII students who were taken by simple random sampling technique. The instrument used is a standard test instrument used by TIMSS (Trends in International Mathematics and Science Study) by selecting content about the concept of gravity. Research data were analyzed using descriptive statistics. The results of the data analysis showed that only 32.14% of students were able to answer questions correctly. When compared with the average percentage of students at the international level for the same concept (Gravity), the number of students at SMPN 1 Aikmel is still below the international average (48.28%). This shows that the level of students' understanding of concepts at SMP 1 Aikmel is below the international average. This can be used as an illustration for teachers at SMPN 1 Aikmel and even for junior high school teachers in East Lombok Regency, considering that SMPN 1 Aikmel is the school with the second-highest National Exam (UN) scores in East Lombok.

Abstract

A study has been carried out on the estimation of X-ray dose on hereditary effects on conventional radiography. The research was conducted at the Bali Academy of Radiodiagnostic and Radiotherapy Engineering using a Raysafe X-Ray Multimeter. Secondary data was obtained in the form of results of checking the output voltage (kV), exposure time (ms) and exposure (mGy). The data obtained are then grouped according to the voltage used. The data is used to calculate the Entrance Surface Dose (ESD) value, which is then used to find the value of the Hereditary effect on the examination of each organ. In this study, the lowest ESD value was found at the use of a voltage of 40 kV, namely 0.3737 mGy, while the highest ESD value was at the use of a voltage of 80 kV, which was 0.7328 mGy. Based on the calculation of hereditary effects for generation I has the highest probability compared to generation II, this is very dependent on the ability of cells after exposure to radiation. Cells in general can make natural repairs. The longer the time after exposure to radiation, the more cells have the opportunity to repair the effects of radiation. So the probability of the risk of hereditary effects in generation II will be smaller.
