Abstract

Telah dilakukan pengamatan deformasi pada kawasan pesisir pantai dalam siklus interseismic dengan menggunakan Global Positioning System (GPS) pada lima titik pemantauan di wilayah Bengkulu bagian selatan. Pengamatan GPS dilakukan dalam kurun waktu 2019-2020 kecuali untuk stasiun DEYU pada kurun waktu 2014-2016. Pengolatan data GPS dilakukan dengan menggunakan software GAMIT/GLOBK. Hasil pengolahan berupa posisi harian GPS time series dalam komponen utara dan timur yang kemudian dilakukan linear fit untuk mendapatkan vektor pergeseran. Kecepatan pergerakan pada stasiun GPS berada 22,23-27,67 mm/tahun dengan error pengukuran < 2,5 mm/tahun. Dari hasil penelitian ini menunjukkan adanya aktivitas deformasi interseismic di wilayah pesisir Bengkulu bagian selatan dengan arah vektor pergeseran hasil pengamatan menuju ke arah timur laut. Vektor pergerakan interseismic yang teramati masih perlu dikoreksi terhadap rotasi Blok Sunda, sehingga vektor pergerakan interseismic yang diperoleh hanya berasal dari pergerakan zona subduksi Sumatera dan sesar Sumatra yang berguna sebagai input pada pemodelan potensi kegempaan di Sumatra khususnya di daerah Bengkulu.

Abstract

The hot spring pool, Lemeu Village, Lebong Regency, is one of the geothermal fields. This research aims to identify the study area's geothermal potential and lithology. This is illustrated by the correlation method of resistivity and electrical conductivity values of rocks based on geoelectric measurements. This research uses the Wenner-Schlumberger configuration geoelectric method, as many as four tracks spread around the hot spring hill with a length of 480 meters, which are used to see variations in resistivity values that can indicate the presence of hydrothermal potential. The result is a 2D Resistivity model processed with Res2DinvX32 software. Based on the interpretation results, the subsurface rock lithology in each track is relatively similar in color, texture, grain size, and composition because it is around the hill. The Hulusimpang formation consists of clay, silty sand, tuff, andesite, basalt, and granite. Hydrothermal is found on lines 2 and 4 with resistivity values of 7.3 and 10.1 Ωm at a depth of 26 meters. Geothermal potential in the research area is divided into several temperature categories; some have low, medium, and high temperatures. In the research area, tracks 1 and 3 have low temperatures.

Abstract

This study examines the linguistic landscape of public signage at Hang Nadim International Airport in Batam, which typically features three languages simultaneously: Indonesian, English, and Korean. The study aims to (1) map the patterns of language use on public signage, (2) analyze the status and functions of these three languages, and (3) explain the factors underlying their presence, particularly that of the Korean language. This study employs a descriptive qualitative approach, utilizing data consisting of nine public signifiers collected and analyzed online from Padang, supplemented by the personal experiences of the researcher, who resides in Batam. The data were analyzed using the theory of informative and symbolic functions, the concept of code preference, and the distinction between top-down and bottom-up signifiers. The research findings reveal a highly consistent language hierarchy, in which Indonesian is always given priority through its top position, largest size, and most striking color, followed by English, with Korean in the most subordinate position. This trilingualism is systematic and top-down in nature, extending even to spaces with Islamic cultural characteristics such as prayer rooms, while commercial signage does not follow this pattern. The presence of the Korean language is not determined by geographical proximity, but rather by a partnership with Incheon International Airport regarding airport management. The study concludes that the presence of a language on visual signage at international gates is driven by economic power and institutional policies, rather than demographics or local identity alone.

Abstract

This article was written to analyze the speech acts of female and male teachers in language learning in junior high schools, classify the types of speech acts used by teachers, and identify speech acts from a gender perspective. This study used a descriptive qualitative approach. The data in this study were collected from one female teacher and one male teacher. The research instruments used included data triangulation; observation, interviews, and documentation. The data analysis technique used was descriptive analysis. The results of the study show that there are distinctive characteristics of female and male teachers in their speech acts during language learning, whereby female teachers tend to use structured, detailed, and systematic speech, while male teachers tend to use dialogic, exploratory, and process-oriented speech acts. In addition, male teachers' speech acts are more straightforward and to the point, while female teachers' speech acts emphasize politeness and familiarity.
