Abstract

Lake Linow is one of the volcanic lakes that has geothermal activity characterized by geothermal manifestations in the form of hot springs that appear on the surface. The purpose of this research is to study the type of fluid and estimate the reservoir temperature. The methods used in this research are ion analysis of fluid content using spectrometry, pH, and physical analysis of fluids in the form of physical appearance manifestations of hot springs. The results showed that the hot springs in Lake Linow are immature water types with a high percentage of Mg concentration. It is interpreted that there is a process of dilution with other elements and mixing with meteoric water which is rich in Mg elements. Calculations using water geothermometer equations on hot spring samples in the area are estimated to have a reservoir temperature of 92.85°C-127.9°C

Abstract

The increasing population of the world's population results in the need for energy to continue to increase, therefore the Indonesian government develops energy outside of fossil fuels, one of which is geothermal. Geothermal is one of the alternative energy source that is relatively new and renewable and can be renewed because production waste in the form of water is re-injected and produces a recycle process that allows sustainability. Geological surveys, geochemical surveys, and geophysical surveys are characterizations that need to be carried out in describing geothermal potential. The purpose of this study was to determine the type of fluid and molecular functional groups of hot springs in Tempang Village, Minahasa Regency. With the geochemical method using a spectrophotometer and FTIR (Fourier Transform Infra Red) spectroscopy, it is known that the type of fluid in the hot springs in Tempang Village is Bicarbonate (HCO3) type with a content of 69 mg/L and the molecular functional group is O-H and C=O.

Abstract

The island of Sulawesi and its surroundings regionally shows a complex geological structure with mineral complexity due to the accumulation of collisions from various Australian and Pacific macro plates. North Sulawesi Province is one of the areas that have alteration rocks that are commonly found in geothermal manifestation areas. The purpose of this study was to determine the element composition and types of rock minerals in steaming ground and warm ground in Tondangow, North Sulawesi Province. The method used is the electron beam method on SEM, and the energy dispersive X-ray spectroscopic method and FTIR spectroscopy. The results obtained indicate that the composition of rock elements in the steaming ground in Tondangow Village, Tomohon, North Sulawesi Province is O, Si, and Al with the percentage content of O 51.96 percent, Si 40.37 percent, and Al 7.67 percent. For warm ground rocks obtained O and Si content, with the percentage of O 54.40 percent and Si 45.60 percent. The type of rock mineral in the steaming ground is obtained by quartz and kaolinite minerals, which are dominated by quartz. For rocks on warm ground obtained the type of mineral quartz

Abstract

The Lahendong Geothermal Power Plant (PLTP) is the largest power plant in North Sulawesi. Turbine is one of the important components in a power plan, so performance and efficiency must be considered. Environmental temperatures that change on a daily basis can potentially affect turbine performance and efficiency. Therefore, it is necessary to analyze the turbine to determine whether the ambient temperature can affect the performance and efficiency of the turbine. The results of the study for 14 days at 10.00 and 22.00 showed differences in the value of turbine performance and efficiency. The turbine performance value is greater during the day than at night. Turbine efficiency is affected by the ambient temperature, when the ambient temperature increases there is a decrease in efficiency and when the temperature decreases there is an increase in turbine efficiency

Abstract

Geothermal Power Plant in Lahendong is the largest power plant unit with environmentally friendly energy, with geothermal resources in North Sulawesi. At the Geothermal Power Plant in Lahendong unit-2, there are important components used to convert steam into electricity. These components include a demister, turbine, condenser, generator, cooling tower, injection well, and also a heat exchanger. One of the important pipes in the line of the Geothermal Power Plant is the pipe between the demister to the turbine. In the flow of steam in the unit-2 pipe from the demister to the turbine, it may experience heat loss during steam flow. The purpose of this study was to determine the amount of heat loss in the pipe from the demister to the turbine at Geothermal Power Plant Lahendong unit-2. This research uses the Steam Tabie application and Microsoft Excel. In this study, the results of the calculation of heat loss along the pipe from the demister to the turbine at the Lahendong Unit-2 Geothermal Power Plant amounted to 4465699 kJ/s

Abstract

The level of salinity in water quality is one of the determining factors in the success of seaweed aquaculture production. The purpose of this study was to develop a website-based monitoring system for the level of water salinity in seaweed ponds. Monitoring system development is carried out by designing and developing an integrated website. Measurement of water salinity in ponds uses a sensor with a microcontroller connected via the internet network so that monitoring can be carried out without the need to go to the pond location. This type of research is development (Research and Development) which refers to the waterfall model (Planning, Analysis, Design, Implementation, Maintenance). The results of the research show that website development as a monitoring system has been successfully developed. There are four pages that can be displayed on the website for monitoring seaweed pond water salinity, namely the login page, homepage, viewing data, and monitoring water salinity. This research is expected to provide an overview in monitoring water quality in increasing the productivity of seaweed cultivation.

Abstract

Clackers are one of the most popular toys in Indonesian society today. There are many physics concepts in this toys that can make clackers as a source of learning physics. The purpose of this research is to examine the concepts of physics, especially the concepts of momentum and collisions in clackers’ games. The method used in this study is a qualitative method with an explanation in the form of descriptive analysis. Literature study and observational analysis were used in this study. This study provides an illustration that every ball's motion in the clackers’ game contains the concept of momentum at each point of its motion and collision when the two balls collide. The results of this study are expected to explain that clackers have the potential as a source of learning physics.

Abstract

Symbolic computing emphasizes the exact processing of data representations. The exact representative states that even though the output is small, the data generated using processing can produce larger mathematical expressions. To overcome this problem, a method needs to be used in representing data. This process is carried out to solve a physical problem in the case of the center of gravity on a triangle. Symbolic programming languages can convert rational numbers, so that this symbolic processing can be applied to inductively validate geometric theorems in the case of triangular center.

Abstract

North Sulawesi has a fairly large geothermal potential, this is evidenced by the emergence of several types of geothermal manifestations, one of which is in the village of Tempang. The purpose of this study was to determine the microstructure of rocks and the types of rocks contained in the rocks in the manifestation area in the village of Tempang. The method that will be used in this research is to analyze in the laboratory using SEM-EDX and FTIR. The results showed that the mineral content and types of minerals around the geothermal manifestation in the form of steaming ground had 3 mineral elements, namely oxygen, silica, and aluminum. The percentage results from EDX for sample 1 contained Oxygen (O) 43.72%, Silica (Si) 54.12%, and Aluminum (Al) 2.16%. For sample 2, the content of oxygen (O) is 51.10% and silica (Si) is 48.90%. This is in accordance with FTIR measurements obtained that the mineral type of steaming ground rocks in Tempang Village is Quartz (SiO2).
