Abstract

Geothermal is one of the alternative energy sources that are classified as new and renewable (new and renewable). This is because geothermal energy sources are still relatively new and are said to be renewable because production waste in the form of water is re-injected and produces a recycle process that allows sustainability. The process of exploration, exploitation and production does not produce toxic gas emissions. In terms of prospects, geothermal itself is a promising energy in the future because the source is heat from within the earth that will never run out. One of the areas in North Sulawesi that has the potential for geothermal project development is located in the Tomohon area, North Sulawesi Province. Based on the preliminary survey that has been carried out, at this location found manifestations in the form of hot springs located in the Pine Forest. The purpose of this study was to determine the type of fluid and functional groups of molecules manifesting hot springs in the Tomohon pine forest tourism area. Analysis of the ion content in the fluid using spectrophotometer characterization, and analysis of molecular functional groups using FTIR (Fourier Transform Infra Red) spectroscopy. The results showed that the type of fluid manifestation of the hot springs in the Tomohon Pine Forest Tourism Area has the type of bicarbonate (HCO3). Analysis of functional groups of fluid molecules in the manifestation of hot springs in the Tomohon Pine Forest Tourism Area has functional groups C=O, C≡C and O-H.

Abstract

The Probabilistic Seismic Hazard Analysis (PSHA) method is a method used in seismic hazard analysis based on the definition of a probability distribution function that takes into account and combines the uncertainties of the earthquake event scale, location, and frequency of occurrence, to obtain a comprehensive picture of the hazard level or a location that reviewed. The Likupang area, North Minahasa is a location that is prone to earthquake disasters, for this reason, early mitigation is needed, one of which is mapping the potential for disaster hazards. Maximum ground vibration acceleration (PGA) is the greatest value of ground acceleration at a place caused by earthquake vibrations in a certain period of time. In this study, the results of the PSHA calculation in the North Minahasa Likupang area were obtained, the largest PGA value was 1.4g–1.8g, tilapia SA T= 0.2 seconds was 1.7g-2.1 and SA T=1 value, 0 seconds is 0.5g – 0.6g. Based on these results, the danger of light to severe damage can be caused.

Abstract

In analyzing the risk of an earthquake it is necessary to have parameters used, one of which is the maximum ground acceleration or Peak Ground Acceleration (PGA). Some data is not fully available on the accelerometer network. Therefore, the purpose of this study is to select an appropriate GMPE equation to estimate the PGA size in Manado City. The selection of the GMPE equation in this study considers the relative difference value and the correlation coefficient in the GMPE equation. Based on these results, the formulation of Kanno, et al. (2006) was chosen to be the initial GMPE equation in the Manado City area. The equation is modified to get an equation with new coefficients. From the results of this equation, it can be determined that the city of Manado often experiences any type of earthquake and also gets the mitigation that needs to be applied.

Abstract

Cooling water has a role in the process of condensing steam from the turbine to the condenser. Cooling water has an effect on maintaining the vacuum pressure in the condenser, so that the steam going to the condenser is maximally condensed. This study aims to determine the effect of variations of the cooling water temperature on the efficiency and performance of the turbine.. The research begins by reviewing the turbine conditions and turbine specifications including the surrounding environment. The higher the cooling water temperature, the greater the efficiency achieved. When the cooling water temperature is 29.14℃ the turbine efficiency value is 72% with the turbine performance value achieved is 627.568 kJ/kg. When the cooling water temperature is 30.43℃ the turbine efficiency achieved is 80% with the performance value achieved is 570,994 kJ/kg. The results also show that the higher the cooling water temperature, the turbine performance value will decrease and vice versa if the cooling water temperature decreases, the turbine performance value will increase.

Abstract

Indonesian An archipelago country that has many volcanoes, namely 147 volcanoes 127 of which are active volcanoes. Spread in several regions of Indonesian following the boundaries of the active plate starting from the islands of Sumatra, Java, Bali, West Nusa Tenggara, Flores, Sulawesi and Maluku. Soputan volcano is one of 127 active volcanoes in Indonesia, is a Strato volcano. As an active tecto-volcanic country, with many volcanoes we try to minimize and prevent the dangers posed by volcanic eruptions. Based on these thoughts, to date in Indonesian various methods of volcanic natural disasters have been carried out, including earthquakes (seismic). Volcanic earthquakes usually occur in the area around volcanoes and their magnitudes are generally very small, averaging less than 5 on the Richter Scale. The depth of the volcanic earthquake ranges from 0-40 km. Based on the hypocentrum distribution of the depth of the epicenter, it shows that the earthquake point that occurred before the eruption was at a depth of 0 km - 2 km at sea level, while the point of the earthquake that occurred during the eruption was at a depth of 0 km - 2 km below sea level, the point of the earthquake that occurred after the eruption it is at a depth of 0 km - 3 km below sea level. The mechanism for the eruption of Mount Soputan Volcano is a visual change in the vegetation around the crater, the plants turn yellow and can die, as soon as the thin crater turns gray.

Abstract

Indonesia is a country with great geothermal potential because it is located at the meeting point of three large plates, and North Sulawesi is right in the ring of fire area, so it has large reserves of geothermal energy. The research area located in Karumenga Village, North Langowan District, Minahasa Regency, North Sulawesi Province was chosen as the research location because in that area there are surface manifestations in the form of hot springs which are estimated to come from a geothermal system. The purpose of this study was to determine the fluid characteristics and reservoir temperature estimation at the research site using geochemical methods andanalysis was carried out using the Na-K-Mg geo-indicator and the Na-K Giggenbach geothermometer. After plotting laboratory chemistry data on Giggenbach's Na-K-Mg ternary diagram, it shows that the fluid characteristics of the hot springs at the research site are partial equilibrium water where the fluid has partially changed so that it is not completely in a state of equilibrium. and based on calculations using a Na-K geothermometer, it was found that the estimated temperature of the hot spring reservoir in Karumenga Village, North Langowan District is 209.638 oC and is included in the medium enthalpy system.
