Abstract

This study investigates physical properties parameters of the soil in landslide prone areas in West Battang Village, Palopo City. This study aimed was to determine the grain size of the soil, the value of soil permeability, and the distribution characteristics of the soil in landslide-prone areas. The 30 samples were taken randomly at a depth of 30 cm, then tested the soil grain size, permeability, and the samples distribution. The results showed that the grain size of the soil consisted of gravel, coarse sand, medium sand, and fine sand, with a size of approximately 0.075 – 4.75 mm. The soils in West Battang Village are dominated by sandy soil. The grains soil in the West Battang Village is dominated by coarse sand. The physical characteristics of the soil grains in this area are classified as poorly graded due to incomplete grain size with soil permeability values in the range of 0.5 – 2.0 cm/hour which can absorb water in category of moderately slow. These permeability values can be categorized as a moderately slow and can stimulate landslides due to gradually accumulation of water in the soils.

Abstract

Akibat kemajuan Teknologi Informasi dan Komunikasi (TIK), media pembelajaran saat ini semakin beragam. Penting bagi guru untuk cerdas dalam memilih media yang tepat untuk memudahkan siswa memahami materi yang disampaikan. Namun, pada kenyataannya inovasi dalam media pembelajaran tidak dimanfaatkan secara maksimal dalam proses belajar. Hal tersebut menyebabkan terjadinya kesulitan dalam memahami dan membayangkan konsep fisika yang abstrak dan matematis. Salah satu materi yang dianggap sulit oleh sebagian peserta didik adalah materi gelombang mekanik. Rendahnya pemahaman konsep gelombang mekanik dapat disebabkan oleh beberapa faktor, salah satunya kurangnya partisipasi siswa selama proses pembelajaran berlangsung. Media pembelajaran fisika berupa buku teks, animasi konsep, simulasi sederhana, sampai pada proses evaluasi belajar dapat dikemas menjadi suatu bahan ajar yang dapat di akses melalui website sehingga sangat fleksibel digunakan. Media pembelajaran berbasis website dapat menurunkan suasana yang statis serta dapat menciptakan proses pembelajaran yang efektif, menarik, interaktif dan dapat membangkitkan motivasi belajar siswa. Dalam pembuatan website, platform Wix menjadi alternatif yang sangat cocok. Wix memiliki fitur yang mengumpulkan konten multi bahasa dan memungkinkan penambahan video, dokumen, animasi, dan audio. Berdasarkan hal tersebut maka dilakukan sebuah kegiatan pengabdian pelatihan pembuatan media pembelajaran Fisika berbasis website menggunakan platform Wix pada materi gelombang mekanik di SMA Negeri 5 Takalar. Wix dipilih sebagai platform karena memudahkan akses dan pengaturan pembuatan website tanpa memerlukan pengetahuan dalam pemrograman. Wix juga menyediakan hosting dan domain secara gratis. Selain itu, tampilan dashboard Wix sangat mudah dipahami oleh pengguna, baik untuk posting konten maupun optimasi website.

Abstract

Pada tanggal 15 Januari 2021, pukul 02.28 WITA 2021 terjadi gempa bumi signifikan dengan magnitudo M 6,2 di wilayah pesisir barat pulau Sulawes. Gempa bumi tesebut disebabkan oleh aktivitas sesar lokal Mamuju dengan pola patahan naik (Thrust Fault). Gempa bumi majene-Mamuju memberikan dampak kerusakan yang besar pada konstruksi bangunana yang berada dipermukaan khususnya pada wilayah kota Mamuju yang menjadi ibukota wilayah Sulawesi Barat. Perlu adanya evaluasi untuk menganalisis dan memodelkan ancaman dampak gempa bumi di wilayah kota Mamuju. Salah satu motode yang dapat digunakan untuk mengevaluasi kerentanan seismik suatu wilayah dapat menggunakan metode Horizontal to Vertical Spectral Ratio (HVSR). Data yang digunakan merupakan data sinyal microtremor dari hasil pengukuran lapangan sebanyak 39 titik menggunakan portable seismometer TDS-303 jenis short period. Terdapat empat parameter output yang dapat digunakan untuk menganalisis dan engevaluasi kerentanan seismik yaitu frekuensi dominan (f0), faktor amplifikasi (A0), indeks kerentanan seismik (Kg), dan periode dominan (T0). Dari hasil pengukuran di lapangan, maka output HVSR tersebut dapat dipetakan untuk mengiterpretasikan sebaran data secara spasial. Hasil penelitian menunjukkan jika wilayah kota Mamuju memiliki nilai frekuensi dominan (f0) antara 0,608 Hz-0,97 Hz, faktor amplifikasi (A0) antara 1,01-7,69, indeks kerentanan seismik (Kg) antara 0,468-73,886, dan periode dominan (T0) antara 0,09 s-1,64 s. Dari hasil tersebut wilayah kota Mamuju yang berada dekat dengan pesisir pantai memiliki potensi kerentanan terhadap bahaya gempa bumi yang jauh lebih tinggi, jika dibandingkan dengan wilayah yang berada di sebelah selatan. Hal ini juga didukung oleh hasil perhitungan ketebalan sedimen yang berkisar antara 7,6 m-130,2 m dengan wilayah utara jauh lebih tebal dari wilayah sebelah selatan. Sehingga wiilayah pesisir kota Mamuju relatif lebih rentan terhadap potensi amplifikasi gelombang seismik dipermukaan.

Abstract

The impact of climate change has emerged as a strategic issue threatening the national interests and environment, particularly in the context of Tana Toraja in the tropical region of Indonesia. The process of climate change, influenced by both natural factors and human activities, has led to a global increase in temperatures and climate anomalies. The risks of natural disasters, especially those related to rainfall such as floods, landslides, and the spread of diseases, are on the rise. The Indonesian government needs to design region development strategies with low greenhouse gas emissions and control deforestation. This study employs a qualitative descriptive method and utilizes data from the Pongtiku Toraja Meteorological Station from 2000 to 2019 to analyze the patterns of climate change and the impact of the El-Nino Southern Oscillation (ENSO) in Tana Toraja. The research findings indicate a decrease in the annual average air temperature, an increase in air humidity, and a shift in rainfall patterns towards an equatorial climate type. The impact of ENSO on air temperature, humidity, and rainfall is variable. Predictions suggest a decrease in rainfall, but combined analyses show an average increase of 4.5% per year until 2029. This conclusion provides a holistic overview of climate dynamics in Tana Toraja, crucial for understanding and planning adaptation for the future.

Abstract

Climate change occurs due to global warming, resulting in irregular seasonal shifts and ecological disasters such as floods or droughts that cause substantial losses. This research aims to determine the influence of climate variability on drought conditions by analyzing drought using the Standardized Precipitation Index (SPI) method. The data used consists of monthly rainfall over 40 years, from 1981 to 2020, obtained from CHIRPS satellite and observation data located in Sleman District. From the 40-year data divided into ten-year periods, severe droughts occurred in the second and fourth periods, specifically from 1991 to 2000 and from 2011 to 2020. The highest frequency of drought occurrences from the entire dataset also happened during the 1991-2000 period. Climate variability, based on the Schmidt-Ferguson climate types, shows climate changes by calculating the Q value. Initially, from 1981 to 1990, the Q value ranged from 33.3 to 60, categorized under type C climate. However, from 1991 to 2000, the Q value ranged from 33.3 to 100, with climate types categorized as C and D. Climate pattern changes have occurred from 2001 to 2010, with climate types ranging from B to D. Spatial analysis scale changes were observed from 2011 to 2020. These conditions indicate climate pattern changes in Sleman District over the 40-year period. The relationship between drought index and SPI method with climate variability (Q) values indicates a weak to moderate relationship with a significance level of 5%. This suggests climate change affects rainfall patterns and drought levels. The correlation coefficient values indicate a moderate relationship, with correlation coefficient values ranging from 0.3 to 0.5 highest during period II (1991-2000) and period IV (2011-2020).

Abstract

Rapid urbanization in Mamuju City, Indonesia, has altered land cover patterns and contributed to the development of Urban Heat Island (UHI) conditions. This study aims to analyze the spatial and temporal characteristics of UHI in Mamuju City during the dry season (June–September) from 2015 to 2024, and to examine the relationships between land surface temperature, land cover change, and atmospheric temperature. The study integrates ERA5 reanalysis air temperature data with Landsat 8/9 Level-2 imagery using the Google Earth Engine platform. Land cover classification was conducted using the Random Forest algorithm with 200 decision trees, incorporating spectral bands, spectral indices (NDVI and NDBI), and topographic variables. Land Surface Temperature (LST) was derived from Landsat thermal data. UHI intensity was calculated as the difference between mean LST of built-up and bare land areas (urban zone) and the mean LST of vegetated, agricultural, and water areas (rural zone). Pearson correlation analysis was applied on a per-year basis to assess relationships between LST, NDVI, NDBI, and ERA5 air temperature. The results show that UHI intensity remained in the strong category (ΔT = 5.1–7.6°C) throughout the study period. Mean LST increased from 30.6°C in 2015 to 32.1°C in 2024, accompanied by a 69.2% increase in built-up area and a 7.9% decrease in dense vegetation. Land cover classification achieved an overall accuracy of 72.0% with a Kappa coefficient of 0.65. LST showed a positive correlation with NDBI (r = 0.662–0.721) and a negative correlation with NDVI (r = −0.658 to −0.693). ERA5 air temperature showed a weak and statistically insignificant correlation with LST (r = 0.137, p = 0.707). These results indicate that observed surface temperature patterns in Mamuju City are closely associated with land cover composition and change, while coarse-resolution reanalysis data are not suitable for representing intra-urban thermal variability at the city scale.
