Abstract

This research will provide knowledge about the existence of physics principles in rice barn poles. This study aims to analyze what physics principles just the one on the rice barn pole. The type of research used is qualitative research. Data collection was carried out through interviews, observation, and documentation. The research location was conducted in Lembang Roroan Barra'-Barra'. The results of the research show that there are physics principles to the rice barn poles that need to be known, such as density ( ), gravity (w), pressure (p), and balance (F). From data analysis density is strongly influenced by mass and volume. The higher the density of an object, the bigger it will be mass per volume. Stress can occur on the pillar with supporting stones Because the pressure generated on the pole is very large so that on the pole uses stone as a support. The balance can be seen in the pole assembly method which uses the pen and hole method as a static equilibrium

Abstract

The grounding system aims to secure electrical equipment and humans. This study was located around the Auditorium area of UKI Toraja Campus 2 which does not yet have a grounding system. One of the factors to get a small grounding value is the location of the electrode to be planted and to determine the resistance value, measurement is needed. Data analysis consists of calculating the depth of the electrode and several grounding points, with the method that will be carried out in this grounding is grounding the rod with 3 measurements. In this measurement, the depth is 30 cm, 60 cm, and 90 cm. With a minimum and maximum resistance value of 30 cm, respectively 3.85 Ohm and 57.10 Ohm, the minimum and maximum resistance value of 60 cm is 2.35 Ohm and 34.52 Ohm, respectively, the minimum and maximum resistance value of 90 cm depth. also 1.69 Ohms and 24.07 Ohms. The value of ground resistance that meets PUIL 2011 standards at the Auditorium Campus 2 UKI Toraja for a depth of 30 cm is found at 2 points, a depth of 60 cm has 6 points and a depth of 90 cm has 10 points.

Abstract

Prior to the eruption of Lokon Volcano on September 13 2014 at 03.09 WITA, there were 62 volcanic earthquake events recorded by seismometers since September 4 2014. This research aims to interpret the eruption mechanism of Lokon Volcano based on seismic activity in the pre-eruption period. 04 - 12 September 2014. The distribution of source points for volcanic earthquakes, both hypocenters, can be visualized using the seismic method, namely by processing digital seimogram data using Swarm 3.1.0 software, GAD (Geiger's method with Adaptive Damping) and Origin 8. Data used, sourced from three stations, namely, Empung (EMP), Wailan (WLN), Kinilow (KIN). Lokon volcano. The hypocenter distribution of volcanic earthquakes is concentrated at a depth of 0 - 1,500 m above sea level and it was found that the aseismic area which is assumed to be a shallow magma pocket area from the Lokon volcano is at a depth of 1,500 - 3,000 m above sea level. The interpretation results show that the eruption mechanism of Lokon Volcano originates from disturbances in the volcanic system which are thought to be the result of tectonic earthquakes in the subduction zone. This causes the magma to rise upwards to supply shallow magma pockets until it reaches maximum pressure and an eruption occurs.

Abstract

The stability of the atmosphere can affect the weather conditions in an area. This study aims to compare atmospheric stability carried out in Lake Linow which has two surfaces, namely the surface of geothermal manifestation and the surface without geothermal manifestation. In determining the stability of the atmosphere, researchers use the Richardson number method. To determine atmospheric stability using the Richardson number, data on wind speed and temperature at each altitude are needed. The measured height is 2 meters and 4 meters from the surface. The results of this study show that on the surface geothermal manifestations have unstable atmospheric stability with Richardson numbers -1.4729 to -0.1420, while on the surface without geothermal manifestations have 3 states of atmospheric stability, namely: stable, neutral, and unstable, with Richardson numbers -1.1316 to 0.9808. Therefore, it can be concluded that the state of the atmosphere on the surface of geothermal manifestations is more unstable, compared to surfaces without geothermal manifestations.

Abstract

To meet future energy needs, the Indonesian government has developed alternative energy sources: geothermal energy. Rano Raindang is one of the areas with a geothermal field due to several geothermal manifestations, such as hot springs. This study aims to examine the fluid type, the reservoir temperature estimation, and the functional group of hot springs. The method used is a geoindicator of Na, K, Mg, Cl, SO4, and HCO3, combining spectrophotometry and FTIR spectroscopy. Research results show that the type of hot spring fluid around Rano Raindang with geoindicators Na, K, Mg is immature waters, this is because the type of hot spring fluid around Rano Raindang has undergone a mixing process, while the geoindicators Cl, SO4, HCO3 are bicarbonate (HCO3) types. This corresponds to the results of measurements using FTIR spectroscopy. The estimated reservoir temperature in the area is 193.66 °C and is included in the medium-temperature geothermal system, as the temperature around Rano Raindang is between 125–225 °C. The functional group of hot spring molecules around Rano Raindang has functional groups C=O and O-H.

Abstract

Viscosity, also known as fluid viscosity, is a fluid characteristic that provides shear stress resistance by the fluid. Viscosity describes a fluid's resistance to a flow so that it can be used to measure fluid friction. The viscosity of a lubricant is affected by changes in temperature and pressure. The pressure increases if the value of the viscosity increases, the higher the pressure, the more significant the fluid's viscosity. This study aims to find out the viscosity value of lube oil in turbine unit 2 of the Lahendong PLTP. Based on the results of the calculation, the result was obtained from the viscosity value of lube oil in turbine unit 2 of 373.61 kg/ms with a pressure of 30591.486 kg/m2, and the viscosity value increased by 386.06 kg/ms due to an increase in pressure of 31611.2 kg/m2.

Abstract

This study aimed to determine the effectiveness of using the Algodoo application in the process of understanding the motion of objects descending an inclined plane. The method used in this research was an experimental method with a quantitative approach to identify the physical quantities of objects descending an inclined plane. The physical quantities were acceleration, velocity, force, potential energy, kinetic energy, and mechanical energy. Based on the data analysis, the acceleration of the object was found to be 4.9 m/s². The velocity of the object changed in a linear equation of 4.9t m/s. The potential energy decreased as the object descends the inclined plane. The kinetic energy of the object increased with the equation 1.2005t² J. The total of potential energy and kinetic energy, the mechanical energy, remained constant at 2.6956 J. These results indicated that Algodoo can be used to analyze physical quantities whose experimental values are close to theoretical ones. Therefore, Algodoo has the potential as an effective learning resource for understanding physics concepts.

Abstract

Ranolewo, located in the Toraget Village, North Langowan District, North Sulawesi, is recognized for its geothermal manifestation in the form of hot springs, indicating the area's geothermal potential. The aim of this study is to characterize the fluid type of the hot spring manifestation in Ranolewo using geochemical methods. The findings reveal a temperature of 52°C at the manifestation site, with a pH level of 5.6, indicating acidic properties. The fluid type identified in the Ranolewo hot spring area is sulfate water. This is attributed to chemical analysis results showing sulfate as the dominant element, along with the presence of SO4 gas. Sulfate water typically forms at shallow depths due to the condensation of geothermal gases nearing the surface. Geothermal gases, comprising air and carbon, are generally dissolved within fluid content in deeper zones but separated from chloride water. Sulfate water is commonly found at the boundary area, not far from the main upflow zone.

Abstract

Geothermal energy is the heat stored within the Earth’s subsurface rocks and the fluids contained within them. Indonesia, located on the Ring of Fire, has significant geothermal potential, particularly in North Sulawesi. This study aims to assess the geothermal energy potential in Sawangan Village, North Minahasa Regency, specifically at the Kepangian River hot springs. The research was conducted by analyzing the fluid characteristics and estimating the geothermal reservoir temperature using geochemical fluid analysis and geothermometer calculations. The analysis Involved laboratory testing of fluid samples, followed by data processing using Na-K and silica geothermometers, and plotting on a Na-K-Mg ternary diagram. The results indicate that the fluid type at the Kepangian River hot springs is immature water, with an estimated reservoir temperature ranging from 240.04°C to 267.01°C, which classifies it as a high-temperature reservoir.
