Abstract

Energy is very important for humans, apart from that the environment also has the same important role, in other words energy and the environment are inseparably linked. This research aims to see the differences in the chemical content and physical properties of geothermal manifestation water and residents’ well water, as well as to find outh whether the manifestation water content affects local residents’ well water. The research samples consisted of hot springs and local well water, where the physical and chemical properties observed were: Temperature, pH, DHL, CL, Fe, H2S,SO4. The results of measurement and sample testing obtained were then analyzed descriptively. The result obtained from this research are that for the physical properties and chemical content of Cl, Fe, H2S, and SO4 there is not much difference in the content analysis results, while for the DHL, Temperature and pH values there are quite large differences, but still is below the standard value for clen water quality.

Abstract

Geothermal is a source of heat energy contained in hot water, rocks, water vapor as well as gases and minerals and others that cannot be genetically separated from a geothermal system. Geothermal energy is a renewable natural resource with high potential. The source of this energy comes from heating magma against water rocks together with elements contained in the earth's crust. North Sulawesi has the potential to become a geothermal development area, both directly and indirectly. The existence of hot springs shows that the research location in Sawangan Village has geothermal potential. This research aims to determine the fluid type and molecular functional groups of hot springs in Sawangan Village, North Minahasa Regency, North Sulawesi Province. Using geochemical methods using Cl-SO2-HCO3 and FTIR diagrams, it is known that the type of hot spring fluid in Sawangan Village is Bicarbonate (HCO3) and the molecular functional group is C=O, where the parent chain C binds HCO3 (Bicarbonate) which corresponds to fluid type results.

Abstract

The conservative energy principle is one of the fundamental concepts in physics used to understand closed mechanical systems. This research aims to analyze the application of the conservative energy principle through a qualitative approach in the loop trajectory on a simple roller coaster. The research method used is descriptive analysis, with information collected through literature study on the loop trajectory as well as concept analysis and formulation of study results. The analysis results explain that the law of conservative energy can explain how the mechanical energy in the system is maintained while going through the loop trajectory by reviewing important parameters such as normal force, minimum speed, radius of the loop trajectory, and minimum height.

Abstract

In chemical experiments, thermocouples offer a better solution than conventional thermometers with fast response, non-intrusive materials, and fairly affordable cost. This research focuses on developing a thermocouple-based solubility meter that utilises the Seebeck effect to detect temperature changes with high accuracy and fast response. This device is designed using a K-type thermocouple, Arduino UNO microcontroller, signal amplifier circuit, and LCD display. The research methodology includes design, calibration, and characterisation of the sensor to ensure accuracy and precision. Tests were conducted on sugar solution, and the results were compared with solubility reference data. The results show that the device has an average error of 0.348% and a standard deviation of 0.114%, proving its reliability in measuring solubility. The conclusion of this research is that thermocouples can be effectively utilised as temperature sensors for solubility analysis, offering a more efficient and economical solution than conventional methods.

Abstract

Single-phase induction motors play an important role in industrial and household applications due to their ability to drive equipment efficiently. PID (Proportional-Integral-Derivative) control is often used to regulate the speed of these induction motors, but determining optimal PID parameters can be a challenge. The Particle Swarm Optimization (PSO) algorithm is proven to be effective in optimizing PID parameters thereby increasing system adaptability and performance. This research combines PID control with the PSO algorithm to create a more intelligent and responsive single-phase induction motor speed control system. Scilab is used as a simulation platform to implement and test this control model. The research results show that combining PSO with PID control is able to reduce oscillations, improve system response, and increase energy efficiency where the initial parameter values are (Kp = 1, Ki = 2, Kd = 3) resulting in new parameter values. after going through an optimization process using the PSO algorithm (Kp = 0.20 Ki = 1.40 and Kd = 2.00). With this optimization, single-phase induction motors can operate more efficiently and reliably in dealing with various operational conditions.

Abstract

This research provides knowledge regarding the existence of physical principles in Toraja pa'gellu dance. This research aims to identify, analyze and describe the physical principles involved in the movements that occur in a pa'gellu dance. The type of research used is qualitative research. Data collection was carried out through observation, documentation and interviews. The location of the research was the lunar dao art studio. The research results show that there are physical principles in pa'gellu dance that need to be known, such as displacement, circular motion, pressure and equilibrium. The movement can be seen from the dancer's initial position to the next position. Circular motion occurs when the dancer rotates around a certain point on one of the toes. Pressure can occur on the soles of the dancer's feet as a cross-sectional area to support the weight of the upper body. Balance can be seen when the dancer cannot balance the body, where when the legs cannot balance the dancer's body can go backwards or forwards and even fall.

Abstract

In this study, Fe3O4@PEG:ZnO nanoparticles were synthesized using the coprecipitation method. Synthesis is carried out to produce nano-sized materials with wide application potential. Synthesis is carried out through three stages, namely Fe3O4 production, Fe3O4 coating with polyethylene glycol (PEG-4000), and Fe3O4@PEG doping with ZnO. Characterization was carried out using X-Ray Diffraction (XRD) tests to analyze the crystallographic properties and structure of the material. The results of XRD analysis showed that the crystal size at Fe3O4 was 7,963 nm and Fe3O4@PEG:ZnO was 6.014 nm. The combination of the magnetic properties of Fe3O4 and the photocatalytic properties of ZnO makes this material have the potential for wide applications in environmental fields, such as the degradation of organic pollutants in water. This research contributes to the development of nanoparticle-based multifunctional materials that support sustainable technology, thereby providing significant benefits for applications in the energy and environmental fields.

Abstract

Nanopartikel Fe3O4 disintesis menggunakan metode kopresipitasi, yang menghasilkan material berukuran nano dengan potensi yang dapat diaplikasikan dalam berbagai jenis bidang. Bahan dasar yang digunakan dalam sintesis ini yaitu FeCl3.6H2O, FeSO4.7H2O, larutan NH4OH, dan aquades. Nanopartikel Fe3O4 dikarakterisasi dengan Uji X–Ray Diffraction (XRD) yang digunakan untuk menganalisis besar ukuran kristalit dan besar parameter kisi dari nanopartikel yang disintesis dengan dua suhu yang berbeda. Dari hasil analisis XRD menunjukkan bahwa ukuran kristalit pada Fe3O4 yang disintesis dengan suhu 40 sebesar 7,82 nm dan besar nilai parameter kisi 8,18 A. Sedangkan Fe3O4 dengan besar suhu sintesis 60 memiliki ukuran kristal sebesar 8,99 nm dan besar nilai parameter kisi 8.17 A. Dari hasil penelitian yang telah dilakukan ini, menunjukkan bahwa pertumbuhan ukuran kristalit nanopartikel Fe3O4 akan meningkat sesuai dengan peningkatan suhu reaksi TR dari 40 C menjadi 60 C.
