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

Petrogenesis is a branch of petrology dealing with all aspects of rock formation from the source, primary process, as well the changes (secondary process) occurring on rocks. The study aimed to determine the mineral element composition and rock mineral types in geothermal manifestation area using SEM-EDAX and FTIR in Candipuro Village Modayag Sub-district. Based on research done at Physics laboratory at Universitas Negeri Manado indicated that mineral element compositions contained in Candipuro Village Modayag Sub-district were Silica (Si), Aluminum (Ai), Molybdenum (Mo), Titanium (K), Niobium (Nb), Bromine (Br), Potassium (K), and Calcium (CA), as well mineral types were albite, quartz, magnetite, and gibbsite.

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).

Abstract

Geothermal Power Plant (PLTP) is a power plant that utilizes the heat generated by the bowels of the earth to produce electricity. efficiency is defined as the ratio between output and input in a process. Efficiency is one of the important equations in thermodynamics to determine how well the energy conversion or transfer process occurs. The research location of PLTP Lahendong unit 2 is located in Tondangow Village, South Tomohon District. This study aims to determine the comparison of the efficiency of cooling tower unit 2 before and after overhaul by processing data using the Ms. software application. Based on the results of the analysis, the efficiency value of the cooling tower of PLTP Lahendong Unit 2 before overhaul has an average value of 59% and the average value of cooling tower efficiency after overhaul is 63%. The magnitude of the efficiency comparison from the overhaul results in the average value of cooling tower efficiency increasing by 4%.

Abstract

Pine Forest is one of the tourist attractions in Lahendong Village, which has geothermal manifestations in the form of hot springs, which shows that the area has geothermal potential. The purpose of this study was to determine the type of fluid manifested by hot springs in the Pine Forest using geochemical methods. The results of this study indicate that the temperature at the manifestation is 40°C while the degree of acidity of the pH of hot water has a value of 4 which indicates the acidity level of hot water is acidic. The type of fluid that exists in the manifestation area of hot water in the Pine Forest is the type of fluid sulphate water and sulfate water is a fluid that is formed at shallow depths and is formed as a result of the condensation process of geothermal gas towards near the surface. This is because the results of chemical analysis show that the element SO4 is the most dominant element and contains SO4 gas. Hot water that has a sulfate type is water that is formed at shallow depths and is formed as a result of the process of condensing geothermal gas towards near the surface. The geothermal gas with gas content (water and carbon) is basically dissolved in the fluid content which is located in the deep zone but separated from the chloride water. Sulphate water is usually at the boundary and not far from the main upflow zone.

Abstract

Geothermal energy is a source of heat energy stored in rocks and fluids contained below the earth's surface. One area that has geothermal potential in North Sulawesi is Pinaesaan Village, Tompaso Baru District. Around the village of Pinaesaan, geothermal manifestations are found, one of which is a hot spring. In determining the prospect of geothermal potential in an area, it is necessary to conduct research on surface manifestations. One of the steps taken in the study of surface manifestations is the calculation of natural heat loss (heat loss) at the research site. The method used in this study is direct measurement in the field by measuring air temperature, manifestation temperature and area of manifestation, which will then be processed through heat loss calculations. Based on the research, the average temperature of the hot spring manifestations in Pinaesaan village is the temperature manifestation 71,3˚C and air temperature 24,7˚C and the area of manifestation 2,94 m2. The value of heat loss is 0,0185 MW, and the speculative resource is 0.185 MW.
