Abstract

Nobita Hill, a tourist site in Padang City, is undergoing development as a tourist destination that offers a bird's-eye view of Padang City. Unfortunately, the hilly topography with steep slopes increases the risk of landslides in this area. In order to address the problem, the community service team from the Physics Department of Andalas University has carried out a six-month community service program from July to December 2022. It focused on disaster awareness education and used a qualitative approach. This activity aims to socialize disaster mitigation efforts, especially those related to landslides and earthquakes, considering that Padang City is also prone to earthquakes. The results of this activity showed an increase in the knowledge of the local community after the socialization, but repeated activities are needed to achieve optimal results. This ongoing activity is essential to ensure continuous improvement in the community's understanding of disaster mitigation and to support efforts to make Bukit Nobita a disaster-resilient area. Thus, this activity makes a positive contribution to shaping a safe, sustainable, and disaster-resilient tourism environment.

Abstract

based on soil magnetic susceptibility (MS) analysis in Tonggo Kenagarian Tigo Koto Silungkang area, Palembayan District, Agam Regency, West Sumatra Province. Soil samples were taken from on two slopes, namely Track A and Track B and one reference point. Samples were measured for low frequency MS (χlf) and frequency-dependent MS (χfd). The results showed that χlf and χfd respectively ranged from 183.7 to 435.5 ×10-8 m3kg-1 and 1.2 to 4.6% (Track A), 416.9 to 600.4 ×10-8 m3kg-1 and 0.9 to 2.2% (Track B), and 365.8 to 638.3 ×10-8 m3kg-1 (reference point). The χlf value of sample of each point on Track A is much smaller than the χlf value of sample of the reference point, while the χlf value of sample of each point on Track B is almost close to the χlf value of sample of the reference point. These results indicate that the slopes of Track A experienced more severe erosion than Track B. The distribution of χlf and χfd values for Track A was relatively straight, whereas for Track B the increase in the χlf value was not followed by an increase in the χfd value. These results indicate that Track A experienced anthropogenic disturbance. The slope of Track A has a greater landslide potential than the slope of Track B.

Abstract

A study has been conducted for slope instability analysis based on magnetic susceptibility values ​​in Nagari Sikucur Tengah, Padang Pariaman. Soil sampling was carried out on two tracks from slopes without vegetation (Path A) and slopes with vegetation (Path B) and one reference point. Measurement of magnetic susceptibility values ​​of samples using the Bartington Susceptibility Meter using two frequencies, namely low frequency (lf) and high frequency (hf). Based on the magnetic susceptibility value at low frequency (κlf), it was obtained that the magnetic minerals that control the reference point samples are ferrimagnetic, while samples from Path A and Path B are ferrimagnetic and paramagnetic, but some samples from Path B are ferrimagnetic. The relationship between the κlf value and the depth at the reference point shows a consistent pattern of decreasing values, while Path A and Path B fluctuate and the κlf value at Path A is much smaller than Path B from the reference point. Based on the frequency-dependent susceptibility value κfd, the sample of Path A is dominated by superparamagnetic domains, indicating that the sample has much smaller grains than the sample of Path B. Both slopes have experienced instability, where the slope of Path A has experienced higher instability than the slope of Path B.

Abstract

A study has been conducted to estimate soil erosion based on magnetic susceptibility values in two areas, namely agricultural land and shrub land in Kanagarian Alahan Panjang, West Sumatra. Samples were taken at five points each at a depth of 10 cm, 50 cm and 100 cm located on a track with a length of 40 m. Measurements of magnetic susceptibility values were carried out using a Bartington Magnetic Susceptibility Meter with two frequencies, namely low frequency (klf) and high frequency (khf). These two measurement results were used to calculate the frequency-dependent susceptibility value (kfd). From the measurement results, it was obtained that the klf value for agricultural land ranged from 1925.3×10-5 SI to 2796.3×10-5 SI and shrub land ranged from 1041.3×10-5 SI to 2304.3×10-5 SI. These results indicate that the κlf value for all samples is classified as high which is controlled by ferrimagnetic minerals. Analysis of the klf and kfd values against depth shows that erosion has occurred on both land areas, where the area of land that has experienced erosion on the scrub land is smaller than on the agricultural land.

Abstract

Metode Inter Aural Time Difference (ITD) dapat diterapkan dalam konteks lokalisasi sumber suara yang terinspirasi oleh prinsip-prinsip mekanisme pendengaran manusia. Robot yang dikembangkan memiliki berbagai potensi aplikasi, seperti di sektor robotik layanan, robot bergerak, dan pengendalian kamera. Metode ITD digunakan untuk mengukur perbedaan waktu kedatangan suara yang diterima oleh dua mikrofon. Sinyal suara yang diterima oleh kedua mikrofon dianalisis melalui teknik cross-correlation, dimana nilai puncak cross-correlation digunakan sebagai parameter untuk mengukur sudut asal sumber suara. Arduino Uno digunakan sebagai komponen utama perancangan robot kemudian dibantu oleh sensor suara serta motor servo. Sumber suara yang digunakan adalah suara beberapa frekuensi dari generator Matlab. Frekuensi suara yang digunakan adalah 300 Hz dengan sudut datangnya sumber suara yang bervariasi antara 5o sampai 170o. Rentang suara yang mampu dibaca oleh robot antara 300 Hz hingga 10,000 Hz sehingga sistem lebih fleksibilitas dalam menangani berbagai situasi dan sumber suara yang karakteristik frekuensinya beragam. Hasil dari Penelitian menemukan bahwa robot mampu mengidentifikasi lokasi asal sumber suara dalam bidang setengah lingkaran (0°-180°) dengan tingkat kesalahan rata-rata sekitar 5,90%. Tingkat keberhasilan penelitian mencapai 94%, menunjukkan efektivitas metode ITD dalam lokalisasi sumber suara. Hal ini dapat menjadi dasar untuk pengembangan lebih lanjut dalam mengoptimalkan robot dalam menemukan dan mengikuti sumber suara dengan akurasi yang tinggi.
