Implementasi Model Pembelajaran Jigsaw Untuk Meningkatkan Pemahaman Konsep Peserta Didik Pada Materi Gelombang Bunyi
type: item
description: Pemahaman konseptual yang kuat merupakan landasan utama dalam pendidikan di abad ke-21. Hal ini krusial agar peserta didik dapat mengembangkan kemampuan berpikir kritis, menyelesaikan berbagai persoalan, dan beradaptasi terhadap perubahan yang dinamis (Kemendikdasmen, 2025). Studi pendahuluan di salah satu SMA di Kabupaten Bandung, yang menunjukkan dimana sebagian besar (65%) dari 300 peserta didik belum mencapai KKM (79) pada mata pelajaran fisika dengan partisipasi peserta didik yang rendah terutama pada materi gelombang bunyi maka memerlukan pendekatan pembelajaran yang inovatif. Penelitian ini bertujuan untuk menguji sejauh mana model pembelajaran kooperatif Jigsaw efektif dalam meningkatkan pemahaman konsep gelombang bunyi pada peserta didik. Metode penelitian ini menggunakan desain pre-eksperimental dengan model one-group pretest-posttest dengan sampel 37 peserta didik kelas XI MIPA yang dipilih melalui purposive sampling. Instrumen yang digunakan berupa tes uraian pemahaman konsep. Data dianalisis menggunakan statistik deskriptif, uji wilcoxon, analisis N-Gain dan perhitungan effect size. Hasil menunjukkan peningkatan pemahaman konsep dari rata-rata 64 menjadi 90 dengan N-Gain sebesar 0,76 yang termasuk kategori tinggi. Uji wilcoxon menghasilkan Asymptotic Sig.Value sebesar 0,01 (p<0,05), menunjukkan perbedaan yang signifikan antara pretest dan posttest. Analisis effect size r mengungkapkan r=0,88 yang termasuk kategori efek besar. Implementasi model pembelajaran kooperatif tipe jigsaw terbukti efektif untuk meningkatkan pemahaman konsep peserta didik pada materi gelombang bunyi. Penelitian selanjutnya disarankan menerapkan model Jigsaw pada materi fisika lainnya yang bersifat abstrak, eksplorasi di tingkat kelas berbeda serta durasi penerapan yang lebih panjang.

Pengolahan Data Mikrotremor Metode HVSR Menggunakan Bahasa Pemrograman Python
type: item
description: The main purpose of this research is to implement the Python programming language in the processing of microtremor data using the Horizontal to Vertical Spectral Ratio (HVSR) method. The microtremor data used in this study was obtained from field measurements conducted at several specific sites. The data are then processed using various popular and effective Python libraries, such as ObsPy, NumPy, and Matplotlib. The data processing involved several important steps, including reading MiniSEED data, filtering with a Bandpass Filter to eliminate noise, segmenting the signal using windowing techniques, and transforming from the time domain to the frequency domain using the Fast Fourier Transform (FFT) method. Furthermore, the HVSR curve is processed with smoothing steps by applying the Konno-Ohmachi method to achieve more accurate results. The analysis results from this process can provide the dominant frequency (f_0), amplification factor (A_0), and seismic vulnerability index (Kg), which are crucial for risk evaluation. In addition, the processed data was visualized in the spatial distribution maps using coordinate data and the image of the satellite. Results from this research demonstrate that Python can be effectively used for the processing and visualization of microtremor data and can be applied to identify the potential seismic vulnerability in the research area with a significant degree of accuracy.

Cut-Off Frequency Analysis On Resistance Values Variation In Low-Pass Filter And High-Pass Filter Circuits
type: item
description: Filter circuit was an electronic system used to filter signals at specific frequencies. In application, signal filtering is often imperfect due to shifts in the cut-off frequency caused by several components in the electronic circuit, one of which was the resistor component. Therefore, this research objective was to find the relationship between resistors and frequency changes to determine the cut-off frequency in low-pass and high-pass filter circuits. This research method used a series of LM741 op-amps by adding capacitor components and resistor variations as active low-pass filter and active high-pass filter circuits, each at the 1st and 2nd order, then connected to a function generator to provide frequency variations ranging from 100 Hz to 1 MHz. The results showed that for first-order low-pass filters, the optimal feedback resistance was 990 Ω, which yielded a cut-off frequency of 7546 Hz with a 3,16% error percentage. For the second-order configuration, a 9720 Ω resistance provided the best results, producing a cut-off frequency of 706.5 Hz with an error percentage of 35,4%. Similarly, for high-pass filters, the optimal resistance for the first-order configuration was 56,200 Ω, yielding a 275 Hz cut-off frequency and a 2,82% error percentage, while the second-order configuration performed best with an 82 Ω resistance, producing a cut-off frequency of 13.075,3 Hz with a 9,2% error percentage. These findings indicate that resistor values significantly influence the accuracy of cut-off frequency in active filter circuits.

Analisis Spektrum Raman pada Sampel Darah untuk Keperluan Forensik
type: item
description: Dalam dunia forensik, identifikasi waktu kejadian suatu peristiwa kriminal merupakan aspek yang sangat penting untuk membantu penyelidikan. Darah adalah salah satu bukti biologis yang paling umum ditemukan di Tempat Kejadian Perkara (TKP). Salah satu metode yang sering digunakan untuk mendapatkan informasi garis waktu kejadian adalah dengan menganalisis bercak darah yang ditemukan di TKP. Salah satu instrumen yang dapat digunakan untuk menganalisis bercak darah adalah dengan spektroskopi Raman. Kelebihan alat ini adalah tidak bersifat merusak sampel, pengukurannya cepat dan akurat, serta dapat dilakukan pada sampel padat, cair, dan gas. Data darah yang diteliti adalah dari 20 orang volunter yang setiap orang memberi sekitar 50 μL darah. Darah tersebut diteteskan pada substrat aluminium foil, dan diukur setiap seminggu sekali, selama 16 minggu. Data hasil pengukuran spektroskopi Raman dilakukan preprocessing terlebih dahulu, sehingga datanya dapat dianalisis lebih lanjut. Didapat pola perubahan bentuk spektrum darah pada sampel yang sama dengan waktu pengukuran yang berbeda. Perbedaan bentuk spektrum disebabkan oleh adanya perubahan struktur hemoglobin yang mengalami oksidasi dan terdenaturasi, dari bentuk deoxyHb menjadi hemichrome. Analisis lebih lanjut dilakukan metode Principal Component Analysis (PCA). Berdasarkan hasil analisis PCA didapat bahwa bercak darah dapat diklasifikasikan berdasarkan subjek individunya dan berdasarkan perbedaan umur bercak darah tersebut. Hal ini dapat dimanfaatkan untuk mencari informasi tertentu untuk kepentingan forensik.

Geothermal Estimation In Pantar, Nusa Tenggara Timur Based On Land Surface Temperature
type: item
description: Pantar Island in East Nusa Tenggara is one of the regions located on the Pacific Ring of Fire and is part of the active volcanic zone of Mount Sirung. This condition gives Pantar great geothermal potential, marked by surface manifestations in the form of hot springs and hot soil. However, the utilisation of geothermal energy in this region is still not optimal due to limited research specifically identifying prospective areas, coupled with high investment and exploration costs. This study aims to estimate geothermal areas on Pantar Island through analysis of surface temperature anomalies (Land Surface Temperature/LST) using a remote sensing approach. The data used are Landsat 9 images with Thermal Infrared Sensor (TIRS) bands. Anomalies were determined using the classify method, which groups temperature values into fewer categories, and the quantile method, which divides the data range into equal numbers of data. In general, temperatures above 37.8 °C are considered LST anomalies. The analysis results show four areas of surface temperature anomalies, with indications of geothermal areas in the northeast of Mount Sirung, covering several manifestations. These findings are expected to provide preliminary information on the geothermal potential of Pantar Island, which can serve as a basis for recommendations for further research and planning for the utilisation of geothermal energy that is economically viable, clean, and sustainable.

Analisis Multi-Panjang Gelombang Erupsi Filamen 29 September 2013
type: item
description: Geomagnetic disturbances in Earth's environment can be caused by Coronal Mass Ejections (CMEs) that reconnect with Earth's magnetic field. CMEs originate from the Sun, carrying magnetic fields from their source. There is a strong correlation between the magnetic flux ropes (FRs) of solar filaments and CMEs that lead to these terrestrial disturbances. CMEs can be initiated by either solar flares or quiescent filament eruptions. Key characteristics of filaments linked to CMEs include magnetic chirality patterns, flux rope (FR) configurations, sigmoid orientations, double ribbon flares, and post-eruptive arcades (PEAs). When a CME carries a flux rope (FR) into Earth's environment as an interplanetary CME (ICME) containing a magnetic cloud, it may subsequently trigger geomagnetic storms. Therefore, this study aims to analyze multi-wavelength filament eruption events to identify filament characteristics associated with geoeffective CMEs and geomagnetic storms. This study aims to analyze the filament eruption using multi-wavelength observations to identify filament properties linked to a geoeffective CME and subsequent geomagnetic storm. A quiet-Sun filament eruption on 29 September 2013 was examined. Automated identification of the filament’s chirality and tilt angle was conducted using H-alpha chromospheric images. The flux rope configuration, sigmoid structure, and PEA were analyzed using extreme ultraviolet (EUV) solar images, while the CME geometry was reconstructed using the Graduated Cylindrical Shell (GCS) fitting method. The filament detection results indicate a dextral chirality with a left-handed helical flux rope, showing a tilt angle of 71.1° consistent with the CME geometry. Examination of solar wind parameters reveals that the filament eruption, carried by a fast CME flux rope, generated a shock upon arrival at Earth. No magnetic cloud signatures were detected in the near-Earth environment. but the CME was geoeffective and triggered a moderate geomagnetic s…

Development of an IoT-Integrated Smart Water Quality Monitoring Device to Enhance Fish Farming Sustainability
type: item
description: A study has been conducted on the development of an Internet of Things (IoT)-based water quality monitoring device to support sustainability in freshwater fish farming. Water quality is a critical factor that affects fish health, growth, and productivity. Manual monitoring of water parameters is often inefficient and less responsive to environmental changes. To address this issue, an automated system was developed by integrating an ESP32 microcontroller with sensors for water temperature, pH, turbidity, and air humidity. Sensor data are transmitted in real-time via Wi-Fi and displayed on the Blynk application, allowing remote monitoring. The research methodology included hardware design and assembly, system programming, sensor integration, and functional testing in a semi-controlled environment. The test results showed that the system operates stably and provides accurate data. The recorded average pH was 7.25, water temperature ranged from 28–29°C, and turbidity was between 18–20 NTU, all of which fall within the optimal range for fish cultivation. This system demonstrates potential as an innovative solution for more efficient and data-driven aquaculture management. The implementation of this technology is expected to assist fish farmers in making timely and informed decisions based on real-time data.

Relocation Of Earthquake Distribution In The Bogor Region Using The Double-Difference Method (Hypodd)
type: item
description: This study aims to improve the accuracy of earthquake hypocenter distribution in the Bogor region by applying the Double-Difference relocation method using HypoDD. This study focuses on seismic data collected from 2023 to 2024 around Mount Salak and Halimun Salak National Park (TNGHS). A total of 219 earthquake events were processed, with 186 of them successfully relocated using the iterative least-squares inversion method. This method utilizes the time difference in the arrival of P and S waves from paired events recorded at the same station to reduce the effects of heterogeneity in the subsurface velocity model. The results showed a significant improvement in hypocenter accuracy, with most hypocenters shifting by 1–2 km and located at shallow depths of 5–20 km. The spatial distribution of post-relocation hypocenters forms a linear pattern that is thought to be associated with unmapped active faults and local volcanic zones. Temporally, seismic activity increased between December 2023 and January 2024, dominated by swarm activity potentially related to tectonic or volcanic processes. These results emphasize the importance of continuous seismic monitoring and integration of additional geophysical data to improve subsurface interpretation and support early warning and hazard mitigation in active seismic areas such as Bogor.

Efektivitas Strategi Deorbit Mega Konstelasi Satelit Starlink Periode Tahun 2019 - 2025
type: item
description: The growth of the Starlink satellite megaconstellation has led to a significant increase in the number of objects in low Earth orbit (LEO), contributing to a higher risk of collisions and the accumulation of space debris. This research analyzes the active deorbit strategies implemented by SpaceX to manage the end of operational life of Starlink satellites. The analysis was conducted based on the orbital decay trends from various launch batches and compared against passive decay scenarios. The results show that the active deorbit strategy thru propulsion systems and controlled maneuvers has proven to be more effective in reducing orbital density, with an average deorbit of 137 satellites per year during the period 2019–2025. This is significantly higher than the theoretical passive estimate of 16 satellites per year. These findings indicate that the implementation of active deorbit strategies plays a crucial role in efforts to mitigate space debris and ensure the operational sustainability of satellites in LEO.

Penerapan Model Think Pair Share terhadap Pemahaman Konsep Siswa pada Materi Gelombang Bunyi
type: item
description: Conceptual understanding plays a vital role in physics education, enabling students to develop logical thinking and construct scientific arguments based on evidence. However, many students struggle with abstract physics concepts and find it difficult to articulate their ideas clearly. This study aims to investigate the impact of the Think Pair Share (TPS) cooperative learning model on students’ conceptual understanding of sound waves. The research was conducted at a public senior high school in Bandung, involving 36 eleventh-grade students. A quasi-experimental method was employed using a one-group pretest-posttest design. The research instrument consisted of essay-type questions administered before and after the TPS implementation. Students’ conceptual understanding was assessed using normalized gain (n-gain). The results showed an n-gain score of 0.87, which is categorized as high. These findings suggest that the TPS model encourages active participation and peer discussion, which significantly improves students’ comprehension of physics concepts. Thus, the TPS model is a promising strategy for teaching abstract topics such as sound waves in high school physics.

The Effect of Calcination Temperature Variation In Pineapple Leaf Adsorbent Preparation On Methylene Blue Adsorption Using NaCl Activator
type: item
description: The use of adsorbents has emerged as a potential solution in wastewater treatment, particularly in addressing pollution caused by heavy metals, dyes, and other organic compounds. However, one of the main challenges still encountered is the relatively low adsorption capacity of adsorbents compared to synthetic adsorbents, which is largely influenced by the pore structure of the adsorbent material. This study aims to optimize the adsorption capacity of pineapple leaf-based activated carbon through cellulose delignification and calcination at varying temperatures of 500°C, 600°C, and 700°C, and to analyze its effects on crystallinity, morphology, as well as adsorption efficiency and capacity for the Methylene Blue (MB) dye. The results show that the highest removal efficiency was achieved at a calcination temperature of 700°C, with an efficiency of 87.07% and an adsorption capacity of 42,27 mg/g. Conversely, the lowest efficiency was observed at 500°C, with an efficiency of 30.15% and an adsorption capacity of 18,09 mg/g. In line with this, morphological characterization revealed that the average pore depth of the adsorbent increased with higher activation temperatures. Thus, it can be concluded that higher calcination temperatures lead to greater adsorption efficiency and capacity of the resulting activated carbon.

Pemodelan Evolusi Sistem Bintang Ganda Tipe Algol Berbantuan MESA (Modules for Ekxperiments in Stellar Astrophysics) : Studi Kasus DN Orionis
type: item
description: The DN Orionis binary star system was a semi-detached binary undergoing mass transfer using Roche Lobe Overflow (RLOF) mechanism. This process played a role in the evolution of both stars, influencing physical parameters such as mass, radius, effective temperature, and orbital dynamics. This study aimed to analyze the impact of mass transfer on the evolution of both stars, focusing on changes in their parameters after the mass transfer ended without extending to their final evolutionary stages. Using MESA (Modules for Experiments in Stellar Astrophysics), the evolution of the DN Orionis system was modeled. Initially, the primary star had a smaller mass M = 1.8 Msun than the secondary M = 3.1 Msun, with an orbital period of P = 2.5 days. Mass transfer increased the primary’s mass to M = 2.9 Msun, while the secondary lost most of its mass, leaving M = 0.23 Msun. The radii and effective temperatures of both stars changed significantly: the secondary’s radius contracted from R = 5.67 Rsun to R = 0.0174 Rsun, while the primary expanded from R = 1.5 Rsun to R = 25.72 Rsun. The primary evolved into a sub-red giant with a effective temperature log Teff = 3.688, while the secondary became a white dwarf with a effective temperature log Teff = 4.2682. Angular momentum redistribution caused the orbital period to increase to P = 20.9 days. This study provided insights into how mass transfer shaped the evolution and parameters of semi-detached binary stars before reaching their final evolutionary stages, demonstrating that significant mass ratio inversion and orbital period expansion are key outcomes of Roche Lobe Overflow in systems like DN Orionis.
