Abstract

This research designs and makes an analysis of the performance of a solar panel-based DC-DC boost converter topology using an Arduino Uno microcontroller. Boost converter is given a variation of inductor wire with 30 turns and 60 turns using a diameter of 1 . This research was conducted to obtain the highest characteristics and efficiency of the performance of the boost converter that has been designed and made for each inductor wire turn variation. In this research, data analysis will be carried out, namely the effect of duty cycle on voltage and current, and how the effect of variations in the number of inductors turns on the efficiency of the boost converter. This circuit uses an arduino uno microcontroller to generate and control the duty cycle on pulse width modulation (PWM) to regulate and increase the desired output voltage. The inductor on the DC-DC boost converter with a wire variation of 60 turns at a diameter of 1  gets the highest efficiency with an average efficiency of 67.13 , while the inductor wire with 30 turns gets an average efficiency of 66.32 .  The maximum voltage generated by the solar panel used as the main source of electrical energy in the boost converter is 20.0  and the control system that has been applied to the arduino uno microcontroller can control and generate a duty cycle with a ratio of 0  - 90 .  The boost converter circuit made gets low efficiency due to the presence of MOSFET components that work in non-ideal conditions, which causes excessive power losses.

Abstract

The island of Sumatra is a meeting area between the Indian Ocean plate in the South and the southwest edge of the Sunda Exposure, which is also the continental plate of Southeast Asia or the Eurasian Plate. The meeting of the plates makes the island of Sumatra an area prone to tectonic earthquakes, including Mount Imun and Helatoba which are located in the Tarutung basin. This study uses the Mohr-Coulomb model in the analysis of changes in coulomb stress. This modeling uses data from earthquakes that occurred on the West Coast of Sumatra which was then processed in coulomb 3.4 software. This modeling resulted in stress distribution in Imun and Helatoba. Coulomb stress changes until this time in Imun is 0.323 bar (2024) and coulomb stress change in Helatoba is 0.217 bar. The effect of the increase in coulomb stress (red lobe) originating from the earthquake on the west coast of Sumatra is triggering 2 tectonic earthquakes at the coordinates of Mount Imun in 2022 and triggering a tectonic earthquake at the coordinates of Helatoba in 2018.

Abstract

Creative thinking ability (CTA) is essential for generating innovative solutions to real-world challenges. This study analyzes high school students' CTA on dynamic fluid topics, focusing on subtopics of flow rate, continuity principle, and Bernoulli's principle. A quantitative survey was conducted with 33 students from a high school in Malang, Indonesia, using a validated essay-based Creative Thinking Ability Test (reliability: 0.880). Descriptive statistics and rubric-based scoring (0–4 scale) categorized CTA levels. Results indicated an overall low CTA (average score: 26.52/100), with flow rate subtopic scoring "very low" (18.18%), while continuity and Bernoulli’s principles scored "low" (34.85% and 26.01%). Indicators like fluency, flexibility, originality, and elaboration were underdeveloped, as students struggled to generate diverse ideas, link concepts, and elaborate solutions. Dominant teacher-centered learning and fragmented conceptual understanding were identified as contributing factors. The study recommends integrating authentic problem-based learning (aPBL), project-based learning (PjBL), and technology-enhanced simulations to foster CTA. These findings highlight the urgency of reforming physics pedagogy to align with 21st-century skill demands.

Abstract

This study aims to identify the level of mastery of physics concepts on static fluid material. This research uses quantitative descriptive methods. The research subjects consisted of 23 MA students in Malang. The test instrument used was a four-point description question. The data collection process was carried out by distributing questions to students who were done for 60 minutes. The results showed that students' mastery of the concept of static fluid was in a very low category. The ability to remember (C1) students scored 51.1%, while the ability to understand (C2) reached 42.4%. The ability to apply (C3) was only 31.5%, and the ability to analyse (C4) reached 32.6%. The low mastery of this concept has an impact on the completion of tasks related to static fluid. Students experience various difficulties, such as assuming that the difference in hydrostatic pressure in a container depends on the shape of the container. Students also have difficulty in solving problems mathematically and assume that the longer the rope of the hanging object, the greater the buoyant force will be. Thus, the difference in buoyant force on an object suspended from a rope is considered to depend on the length of the rope. These findings emphasize the need to improve physics learning in the future, especially in improving the strengthening of the ability to master the concept of static fluid material.

Abstract

Lebong is one of the areas located in Bengkulu Province and is passed by the Ketaun Segment fault. The fault causes several locations in Lebong to have manifestations such as hot springs, solfatara, and fumarole. This research aims to identify rock lithology with 2D modeling using the magnetotelluric method.  The data acquisition process was carried out using a magnetotelluric device with a low frequency of 128 Hz, a medium frequency of 1024 Hz, and a high frequency of 4096 Hz. The sensor in the recording consists of two sensors, namely electric and magnetic. Based on the field survey, the results obtained are several distributions of resistivity values from low, medium, and high. The acquired data was processed using ZONDMT software to obtain 2D modeling. The results of data processing interpret the resistivity value to depth. There are 8 measuring points in one track with a west-southeast direction. Variations in measured resistivity consist of low, medium, and high resistivity.  The distribution of low resistivity values (10-25 Ωm) in this area is identified as the response of the caprock, having a depth of <1.5 km, shown in light blue. The distribution of medium resistivity values (40-150 Ωm) shown in green to yellow is identified as a reservoir zone with a depth of >1.8 km. Rocks with high resistivity values (>300 Ωm) shown in red are identified as hot rock zones. Hot rocks are at a depth of 4-6 km. The range of frequency values on the 2D modeling color scale ranges from 1-800 Ωm. The results of this study can be used as a basis for feasibility studies for local governments to develop geothermal energy projects. By knowing the subsurface characteristics, the potential for geothermal energy reserves in Lebong can be evaluated more accurately.

Abstract

Meningkatnya penggunaan sinar-X di bidang medis disertai dengan kemajuan teknologi yang pesat dan telah berdampak signifikan pada radiologi terapeutik dan diagnostik. Di bidang radiologi diagnostik, modalitas dengan teknologi canggih yang memanfaatkan sinar-X adalah Computed Tomography Scanner (CT Scan). Dosis radiasi CT scan diketahui lebih besar dibandingkan dengan modalitas lain, membuat perlindungan pasien dari paparan berlebihan menjadi prioritas kritis. Oleh karena itu, penelitian ini bertujuan untuk mengetahui pengaruh usia dan massa tubuh terhadap nilai Computed Tomography Dose Index (CTDIVol) dan Dose Length Product (DLP) pada pasien CT Scan di Instalasi Radiologi RS Universitas Andalas, untuk memberikan dosis radiasi yang tepat dan tepat untuk keperluan diagnostik. Prosesnya termasuk mengumpulkan data dosis radiasi pada pasien yang mengalami CT Scan kepala dan perut non-kontras. Hasil penelitian menunjukkan bahwa usia memiliki korelasi yang sangat lemah dengan nilai CTDIVol dan DLP, sedangkan massa tubuh memiliki korelasi yang cukup rendah, kecuali untuk CT Scan perut non-kontras. Penelitian ini menunjukkan bahwa massa tubuh pasien tidak berpengaruh signifikan terhadap pemeriksaan CT scan di RS Universitas Andalas. Dianjurkan untuk mengoptimalkan dosis radiasi dengan mempertimbangkan massa tubuh dan menggunakan Automatic Exposure Control (AEC).

Abstract

A study of wind patterns was conducted to minimize aircraft accidents at Fatmawati Soekarno Airport, Bengkulu City. The data was then processed using the Wrplot application to show the direction and difference in wind speed and create a wind pattern image in the form of a wind rose diagram. This study aims to analyze wind patterns and speeds at Fatmawati Soekarno Airport, Bengkulu City for a period of 5 years (2019-2023) using the Wind Rose method. Data obtained from the Meteorology, Climatology, and Geophysics Agency, Fatmawati Bengkulu Meteorology Station shows that the dominant wind direction comes from the Southeast, Northeast, and North which are influenced by seasonal changes. The results of the analysis show extreme wind speeds ranging from 2.50 - 4.70 m / s which are classified as light winds and are still safe for flight operations. With a deep understanding of this wind pattern, it is hoped that airport managers can optimize the use of runways and improve flight safety by accommodating weather conditions. The results of this study also emphasize the importance of consistent wind pattern monitoring to support risk management related to extreme weather.
