Abstract

The research aims to determine the effectiveness of guided inquiry with Edmodo-based mobile learning system implementation in physics learning. Edmodo is a learning management system application developed for mobile learning that enables students to access tasks and teaching materials anytime and anywhere. This research was quasi-experimental that used a pretest-posttest control group design with 11th-grade students in SMAN 1 Makassar as a sample, and each class consisted of 33 students who were used as the experimental class and the control class. The sample selection was carried out using a purposive sampling technique. The instrument used in this study was a physics learning achievement test in the form of multiple-choice tests. Data were analyzed using the T-test on two samples with test equipment that had gone through expert validation tests and empirical tests. The result of the T-test analysis showed no difference in learning outcomes between experimental and control classes before being treated, this result contradicts the results of the T-test analysis after treatment which shows significant differences in physics learning outcomes in students taught using guided inquiry by applying a learning-based mobile learning system with students taught using guided inquiry without mobile learning system. Based on these two T-test results and by using Cohen-D analysis with the result of 2,980. Therefore, the application of a mobile learning system based on Edmodo is effective in improving physics learning students outcomes in class XI MIPA SMA Negeri 1 Makassar.

Abstract

Sultan Hasanuddin International Airport is an airport with a unique topography, making the process of rainfall formation at this airport very dynamic. To ensure safe flight operations at Sultan Hasanuddin International Airport, rainfall forecasting is needed using fuzzy logic methods, with input data influencing rainfall formation, such as precipitable water, relative vorticity, and divergence. In this study, the data used for applying fuzzy logic can be divided into three types: training data (for developing the fuzzy logic method), validation data (for validating the fuzzy logic method), and testing data (for testing the fuzzy logic method). Therefore, validating the fuzzy logic method to obtain results and accuracy of rainfall events, as well as testing the fuzzy logic method for rainfall event forecasting, are the goals of this research. The precipitable water, relative vorticity, divergence, and rainfall data in this study are divided into three types: training data (2010 – 2021), validation data (2022 – 2024), and testing data (2025 – 2030). The validation results for 2022 – 2024 were dominated by non – rain events, with 7.051 occurrences, while there were 948 occurrences of rain events. The accuracy of the fuzzy logic validation method was found to be 78.58% during 2022 – 2024, allowing the fuzzy logic method to be applied for forecasting rainfall events in 2025 – 2030, beginning with the creation of input data using the moving linear regression algorithm. The forecasting results for 2025 – 2030 using the fuzzy logic method were dominated by non – rain events, with 15.232 occurrences, while there were 2.296 occurrences of rain events.

Abstract

This study aims to implement a problem-based learning model and to measure its effect on students' physics learning outcomes. This research is a pre-experiment using a one-group pretest-posttest research design. The population in this study were all students in class XI MIPA at SMA Negeri 1 Wangi-Wangi for the 2022/2023 academic year, while the sample was 35 students who were selected using the Slovin method. The results of the descriptive analysis showed that the average score of students' physics learning outcomes before using the problem-based learning model was 7.26. Conversely, after using the problem-based learning model, the average score of students' physics learning outcomes was 12.14. The results of the N-gain test analysis showed N = 0.36, which indicated that there was an increase in students' physics learning outcomes after using the problem-based learning model. Therefore, this study concluded that the problem-based learning model is effective in improving the physics learning outcomes of class XI MIPA students at SMA Negeri 1 Wangi-Wangi.

Abstract

The Maros-Pangkep region in South Sulawesi is a tropical karst landscape not officially mapped as an active fault zone, yet it has exhibited increasing micro-seismic activity in recent years. This study investigates the potential existence of hidden faults through hypocenter relocation using the double-difference method. A total of 191 earthquake events with magnitudes of 1-2.6 were successfully relocated using BMKG catalog data and the IASP91 global velocity model. The resulting hypocenters form a northwest–southeast-trending cluster, with fault plane geometry of 333°–346° strike, 8°–9° dip, and ~11 km length. These events cluster along boundaries of the Tonasa, Camba, and intrusive rocks, where competence contrast and karstification localize deformation. To complement the spatial analysis, magnitude–frequency characteristics were evaluated using the Gutenberg–Richter relationship. The estimated b-value of 1.34 indicates a low-stress regime dominated by small-magnitude seismicity, consistent with distributed deformation in brittle, heterogeneous lithologies. Although micro-seismic in scale, the spatial and statistical patterns suggest the presence of a structurally weak and potentially seismogenic zone that is not reflected in current tectonic maps. These findings underscore the importance of including the Maros–Pangkep region of South Sulawesi in seismic hazard assessments and land management efforts. The integration of relocation techniques and seismicity statistics proves effective for detecting latent fault structures in complex karst settings. In addition to seismic risks, such activity may accelerate land degradation through sinkholes, aquifer disruption, and ground instability, highlighting the value of geophysical assessments in managing vulnerable karst environments.

Abstract

This research aims to analyze the characteristics of the Quasi Linear Convective System (QLCS) based on weather radar in the South Sulawesi region, which influences extreme weather. This research is a case study that focuses on the occurrence of QLCS, which grows around the waters of the Makassar Strait and moves east towards the mainland area of South Sulawesi. The study area is limited to a radius of 200 km from the weather radar center. The data processing technique uses the Rainbow application with weather radar data input from the Hasanuddin Makassar Meteorological Station. Next, the radar data output in the form of MAX products is filtered according to the criteria of Lombardo and Colle (2010) to obtain QLCS cases. The selected QLCS cases were then analyzed for their characteristics based on spatial and temporal distribution, type of formation, propagation, and Vertical Wind Shear. The data processing results found 24 cases of QLCS in South Sulawesi with varying characteristics, where the formation location was most often in the waters of the Makassar Strait with a lifetime of around 60-90 minutes. The most common type of QLCS formation is a broken line, and the most dominant QLCS propagation is towards the east, with fast-moving speed and a strong VWS category.

Abstract

Makassar merupakan salah satu kota terbesar di Indonesia yang rentan terhadap kejadian hujan ekstrem sehingga diperlukan indeks peringatan dini untuk meminimalisir resiko yang akan ditimbulkan jika terjadi hujan ekstrem. Data yang digunakan dalam pembuatan indeks peringatan dini meliputi data angin (divergence dan relative vorticity), Madden-Julian oscillation (MJO), anomali outgoing longwave radiation (OLR), dan southern oscillation index (SOI) pada tahun 2017-2021. Hujan ekstrem di Makassar pada tahun 2017-2021 tercatat sebanyak 43 kejadian yang umumnya dipengaruhi oleh pola angin konvergen, pola angin siklonik, dan anomali (OLR) yang bernilai negatif. Hasil indeks dari tiap faktor cuaca saat kejadian hujan ekstrem di Makassar pada tahun 2017-2021 meliputi data divergence (-280,59 µs-1 sampai dengan -25,47 µs-1), data relative vorticity (-236,13 µs-1 sampai dengan -55,23 µs-1), data MJO (fase 1 sampai dengan fase 8), data SOI (-40,11 mb s/d 34,1 mb), dan data anomali OLR (-95,85 W/m2 s/d 9,59 W/m2).

Abstract

Madden Julian Oscillation (MJO) is one of the global phenomena that affects weather and climate conditions in Indonesia. MJO increases the rainfall rate and causes a plethora of extreme rainfall occurrences in areas along its trajectory. Those extreme rainfall events could trigger hydrometeorological hazards that endanger the surrounding environment. As the first step to analyse this extreme weather event, this research tries to determine the threshold of the extreme rainfall rate. The method used for determining the threshold is the statistical method 98th percentile. The next step is to identify the frequency trend of the extreme rainfall in the period of 1991 to 2020, by measuring the rainfall rate and comparing it with the normal value. If the rainfall rate is above the normal condition in a certain threshold, then it is considered an extreme rainfall event. After that, these extreme rainfall occurrences are compared to the active MJO phase to find out the influence of MJO to the rainfall in the west coast of South Sulawesi. Then, the dynamical atmospheric conditions are to be analysed during those extreme rainfall events. The result shows that the frequency trend of extreme rainfall events are generally negative in 5 (five) regions, which means an insignificant correlation between MJO and rainfall rate. In contrast, 3 (three) other regions show a positive trend. The influence of an active MJO on the extreme rainfall rate is about 34,1%. Meanwhile, the rest for about 65,9% is influenced by other factors. The use of MJO indices for generating early warning hydrometeorological disasters is by utilising the MJO monitoring data, supported with the analysis of dynamical atmospheric condition in the west coast of South Sulawesi.

Abstract

Indeks stabilitas memiliki nilai ambang batas dan akurasi nilai ambang batas yang beragam terhadap prakiraan terjadinya awan Cb dan thunderstorm di tiap wilayah, sehingga dengan kondisi tersebut indeks stabilitas sangat menarik untuk dikaji tak terkecuali di Bandara Internasional Sultan Hasanuddin. Indeks stabilitas sangat beragam jenisnya, namun yang umum digunakan dalam memprakirakan terjadinya awan Cb dan thunderstorm adalah SI, LI, TTI, SWEAT, KI, dan CAPE. Pada penelitian ini, ambang batas indeks stabilitas terhadap kejadian awan Cb dan thunderstorm hampir identik satu sama lain dengan bulan Desember merupakan bulan dengan ambang batas terendah dan tertinggi bagi tiap-tiap indeks stabilitas terhadap kejadian awan Cb dan thunderstorm. Akurasi ambang batas indeks stabilitas terhadap kejadian awan Cb lebih baik dibandingkan akurasi ambang batas indeks stabilitas terhadap kejadian thunderstorm yang disebabkan oleh awan Cb yang muncul di suatu wilayah belum tentu menghasilkan thunderstorm namun ketika thunderstorm terjadi di suatu wilayah maka thunderstorm tersebut disebabkan oleh adanya awan Cb.
