Noise is a sound that humans do not want and it is an environmental factor that can negatively affect health. To overcome the noise issue, many efforts have been made to reduce noise levels. An example is the manufacture of the walls of a house using materials with sound and absorbent standards. The materials used can also be derived from types of wood such as plywood, wood panels and calciboards. Therefore, the value of its sound absorption coefficient is calculated to find out which active material is to be used in the manufacture of the building. Based on the research results, the value of the sound absorption coefficient of the three types of materials, it can be seen that the shape of the graph and its analysis states that the lowest sound absorption coefficient is most likely at the lower frequencies and the highest value of the sound absorption coefficient tends to be at the higher frequencies. In fact, when viewed as a whole, the magnitude and magnitude of the sound absorption coefficient on the graph is not in line with the increase in the frequency value.

The purpose of this study was to ascertain the impact of repeated heating of coconut oil on the value of viscosity, density (mass density), surface tension, and the coefficient of temperature reduction rate (Newton cooling constant). The coconut oil sample used was the result of my own production. The heating repetition was carried out at most five times with a peak temperature of 90oC. The physics quantities were respectively determined by the methods of the falling ball, the directly measuring the mass and volume with the measuring cylinder, the raising fluid in a capillary tube, and the Newton cooling.From this study, it was found that there was an effect of repeated heating of coconut oil on the value of viscosity, mass density, surface tension, and the Newton cooling constant. This effect is indicated by the presence of a functional relationship between the heating test and the value of the four physical quantities. The relationship between heating repetition and viscosity is a quadratic function, the relationship between heating repetition and mass density is a linear function, the relationship between heating repetition and surface tension is a quadratic function, and the relationship between heating repetition and Newton cooling constant is a quartic function. The four functional relationships are empirical equations that state the laws of nature in a certain heating range and can be used as material for further studies to reveal the physical mechanisms that build them, including determining the general equations that unite them.

Abstract Ordinary kriging geostatistical method is an interpolation method that used spatial data. This method generally used to estimate coal and mineral resources. However, over time this method is also used in estimating land prices. The purpose of this research is to determine the best model for land price estimation in North Samarinda District, especially in Sempaja Selatan Sub-District between spherical models, Exponential models and Gaussian models and to determine land price estimation using ordinary kriging geostatistical method based on the best semivariogram model displayed in the form of a contour map. The estimation process begins by create an experimental semivariogram and a structural analysis which is carried out to obtain sill, nugget and range. Then, interpolated using the three models to get the predicted value and calculated RMSE to determine the performance of the model, which the spherical model is the best model because it has the smallest RMSE value. From this method, a contour map of the estimation results of land prices in Sempaja Selatan Sub-District of North Samarinda District is obtained. The lowest land prices are found to be predominantly located in the northwest and north of Sempaja Selatan Sub-District. The lowest price of the land range from Rp. 279,000,- to Rp. 900,000,- per m2 and the highest price of land is predominantly located in the southern part of Sempaja Selatan Sub-District with prices ranging from Rp. 2,982,000, - to Rp. 4,981,000, - per m2. The variation in land prices in Sempaja Selatan Sub-District of North Samarinda District is influenced by physical factors, namely the elevation and slope of the slope. Low land prices tend to be in areas of high elevation and steep slopes, while high land prices are at low elevations and with a slope that is flat. So from this, it can be said that the land price is inversely proportional to the physical factor of the land.
