Analyzing Peak Ground Acceleration (PGA) Distribution in IKN Development Area Using Kanai Method

2024-12-25T23:56:22+00:00

This study examines the distribution of Peak Ground Acceleration (PGA) values in the development area of the new capital city (IKN) in Sepaku District, Penajam Paser Utara Regency, East Kalimantan. Although seismic activity in Kalimantan is lower compared to other regions in Indonesia, earthquake risks still need to be anticipated, especially with the relocation of IKN to this area. Earthquake disaster mitigation efforts are conducted through PGA mapping using the empirical Kanai approach, which provides information on potential damage risks due to earthquakes. The study utilizes seismic data obtained from microtremor measurements at 44 points, as well as earthquake data from Paser Regency in 2022 and the 2018 Palu earthquake. The data were analyzed using the Horizontal-to-Vertical Spectral Ratio (HVSR) method to calculate the natural frequency and dominant soil period, which are key input parameters in determining PGA values. The results show PGA values ranging from 0.69 to 34.29 gal, divided into two main zones: low (PGA < 2.9 gal) and moderate (PGA 2.9–34.29 gal). This information serves as a critical foundation for earthquake risk mitigation and safe development planning in the IKN area, particularly in the Sepaku District, East Kalimantan.

2025-01-08T10:41:56+00:00

This study aims to develop Arduino-based parallel series circuit teaching aids to facilitate students in understanding the concepts of Ohm's Law. The method used in this research is to use research and development procedures (Research and Development) with Nieveen's description. The design of teaching aids in this study uses the help of Arduino Uno R3 so that measurements can be made automatically. The props designed by researchers use a 30 ampere acs712 current sensor. Based on the results of the data obtained, the relationship between the voltage and the current produced is directly proportional. This is evidenced when the series circuit given a voltage of 6 volts produces a current of 1.82 A when given a voltage of 7.6 volts produces a current of 2.08 A, and when given a voltage of 9.25 volts produces a current of 2.34 A. Likewise, in parallel circuits, the relationship between voltage and current is also directly proportional. When the voltage given is 6 volts, it produces a current of 1.04 A, when the voltage is 7.6 volts, it produces a current of 1.30 A, when the voltage is 9.25 volts, it produces a current of 1.56 A. Based on these data, it can be interpreted that the greater the voltage given, the greater the current that will be generated. Thus, the research and development of Arduino-based parallel series circuit teaching aids is by the existing literature. This Arduino-based parallel series circuit trainer can be said to have a relatively good level of measurement accuracy. that the props that have been made can work well in series circuits and parallel circuits. The parallel series circuit is arranged using an Arduino uno R3 microcontroller and uses a 30-ampere acs 712 current sensor. The level of measurement accuracy produced is relatively good at around 88%. according to experts, the percentage of similarity of 80%-90% can be said to be good. Thus, this Arduino-based series parallel circuit trainer can be said to have a relatively good level of measurement accuracy.

Proving the Resonance of DO, RE, MI, FA, SOL, LA, SI, High DO Tones by Comparing Frequency of Sound Produced by Wine Glasses

2025-01-08T21:55:49+00:00

Due to the lack of standard laboratory facilities in many schools in Indonesia, the researcher created a simple musical instrument based on the concept of sound physics. The research was to prove the phenomenon of ‘resonance’ with the frequency comparison of the sound from ‘wine glasses’. Eight identical glasses filled with water at different heights to produce the do, re, mi, fa, sol, la, si, and do. The results showed the longer the air column, the higher the frequency of the sound produced. The sound produced by the glasses filled with less water was louder than the glasses filled with more water. This happened because of the resonance between the sound waves produced by the glasses and the sound waves propagating in the tube. Thus, it was following the theory. It could be used in the laboratory. As suggested, the researcher used tall and straight wine glasses to make it easier.

Identifying Student Misconceptions Using Three-Tier Test with Certainty of Response Index on Temperature and Heat Topics

2025-01-10T01:01:31+00:00

This research aims to identify students' misconceptions using a Three-Tier diagnostic test assisted by the Certainty of Response Index (CRI) on temperature and heat material. The data analysis method used in this research is quantitative descriptive and equipped with a three-tier Certainty of Response Index (CRI). The population in this study was class XI 1 IPA MAN 1 Musi Banyuasin with 30 students, and the sample in this study was class. Data collection techniques were used during the observation, test, and documentation stages. The research results showed that the misconceptions identified regarding the concept of temperature and heat were 40%, 36% understood the concept, 6% understood the concept but needed clarification and 18% needed to learn the concept. The misconceptions experienced by students are classified as moderate-level misconceptions with a percentage range of 31% ≥ 60%. The cause of misconceptions is the students' errors in learning context and incomplete reasoning. It is hoped that the results of this research can provide information about misconceptions that occur in the matter of temperature and heat and can serve as a guide for further research to find out the causes of misconceptions and efforts to overcome them.

Development of a VOC (Volatile Organic Compound) Measurement System to Identify Placebo Phenomenon in Emission Areas

2025-01-13T10:06:38+00:00

VOCs (volatile organic compounds) can be used as a biomarker of placebo phenomenon, such as stress, panic disorder, health conditions, and many others. VOCs from the exhaled breath have different concentration levels that are also related to many health diseases. However, the use of VOCs as biomarkers in exhaled breath are very limited. Hence, this study aims to develop a novel e-nose (electric nose) system based on a VOC measurement system to identify placebo phenomenon in emission areas. For this purpose, a digital semiconductor VOC sensor and a microcontroller were used to detect VOC level. The developed system was tested inside a chamber for the initial calibration and comparation steps using fresh air and a comparator device. After calibration, the system was used to measure the VOC concentrations of 20 exhaled breath samples in the emission sampling areas (control and emission sources). In other sides, the VOC levels surrounding the emission areas were also measured using the comparator device. The placebo levels (PLS) of the exhaled breath samples were divided into PLS(-) or placebo negative and PLS(+) or placebo positive related to the placebo conditions. The sampling areas were divided into indoor and outdoor areas to identify the different placebo percentages and the dependence related to the emission levels. The results show that the emission levels of the emission sources are about 504-528 ppb, meanwhile, the control area (clean area) has <10 ppb of VOC levels. A higher VOC concentration, a higher PLS(+) percentage. The exhaled breath of PLS(+) samples contain >78 ppb of VOC levels, while PLS(-) samples has < 78 ppb of VOC levels (p < 0.05). It can be concluded that VOC concentrations in the emission sources has a potential to influence the placebo quantification in human psycological health. The developed e-nose system can be used to identify VOC levels as a biomarker of a placebo phenomenon.

2025-01-23T11:02:03+00:00

The synthesis of nano-silica gel based on magnetic minerals from the coastal sand and river sand of Lombok Island has been carried out. The synthesis method used is sol-gel with HCl acid and NH4OH base. The results showed that nano-silica based on coastal sand has a greater silica content than nanosilica based on river sand. The morphology of nanosilica based on coastal is granular with a smaller grain size of nanosilica based on coastal sand compared to nanosilica based on river sand. To a temperature sensor, nano-silica based on coastal sand has a larger coefficient when compared to nanosilica based on river sand. This indicates that nano-silica based on coastal sand has better physical properties as a temperature sensor than nanosilica based on river sand.
