“…Neumann et al (2017) stated that the sustainability approach in the management of coastal regions must consider the integration between components that cannot be separated. Suasti et al (2020) and Li et al (2022) stated that one of the biggest potentials of coastal region is marine tourism, where the main attraction is natural beauty itself.…”

This study reviews the implementation of policies regarding coastal management in Pariaman City. Coastal regions have huge potential to be developed and maintained through the utilisation of coastal resources and the use of functional regions in a planned, rational, responsible, harmonious and balanced manner. A descriptive qualitative approach was used for this study, focusing on coastal management policies and the impact of the implementation of those policies. The results of this review refer to the Regional Spatial Planning Regulation (RTRW) 2010-2030 for Pariaman City. With the implementation of the strategy for the development of coastal management in a sustainable manner listed in the RTRW 2010-2030 for Pariaman City, there are several positive impacts, including from an economic perspective, namely controlling the mangrove forest area. From a social perspective, there are three positive impacts, namely (1) increasing the spirit of cooperation/togetherness between communities; (2) the emergence of new mangrove farmer groups; and (3) stimulating the growing sense of community participation in the activities carried out by the government. From an environmental perspective, there are three positive impacts as well, namely (1) a wider area for mangroves, which increased from 29 ha to 31 ha; (2) the planting of mangroves that is carried out has a sustainable impact in the long term; and (3) prevent abrasion, and dampen waves.

“…1) involved decoding satellite images and aerial photography, which involved a band combination technique for brightening the images. The brightness value of the same surface material caused by topographic conditions, shadows, and sunlight intensity is seen using this band combination method to more clearly observe the distribution of land cover [11]. Field validation exercises are then conducted on the ground using near-surface geoelectric tools using a Naniura model NRD 22S resistivity-meter and then plotting the field measurement results on the study area's geological map allows for additional interpretation regarding the active fault to get a better geomorphological analysis [12].…”

On February 25 th , 2022, an earthquake with a magnitude of 6.2 in Nagari Kajai, Talamau District, West Pasaman Regency, resulted in considerable structural damage because it originated from a shallow earthquake with a hypocenter depth of 12.6 km and is a manifestation of the strike-slip faulting system linked to the Sumatra Fault System (SFS), which is adjacent to the Angkola segment, Barumun Segment, Sumpur Segment, and Sianok Segment is a newly-found active fault in this area. All of Nagari Kajai (Kajai Village) Sub-district is covered in volcanic deposits, whether they are new (quaternary deposits) or a combination of old (tertiary deposits) and young (quaternary deposits) as a product from the Talamau Mountain and the Maninjau Mountain. These geological activities will provide a good impression of the topography and geomorphology of a newly found active fault, The Kajai Fault. The geomorphological analysis is used to get new characteristic features for this new fault line continuation using Landsat 8 imagery and supported by aerial photography using Unmanned Aerial Vehicles (UAV). A 2D subsurface image was obtained from the Wenner-Schlumberger geoelectric survey configuration to get an excellent subsurface interpretation of lithology in this area. From this interpretation, the Kajai Fault is present in a valley filled with volcanic products and a narrow diversion of the Batang Talu River. The geoelectrical survey images show a double juxtaposition from two interpreted faults, namely F1 and F2, which run through The Kajai village and are suspected to be one of the shallow earthquake sources.

Tingginya polutan yang masuk ke perairan akan menyebabkan eutrofikasi, sedimentasi, polusi serta masuknya air tawar yang berlebihan dari darat ke laut, yang akan berpengaruh pada keberlangsungan sumber daya terumbu karang yang ada di perairan, dimana jenis karang dan kualitas terumbu karang juga berkurang, hal ini biasanya disebut dengan fenomena kehilangan keanekaragaman hayati atau biodiversity lost (Graham et al (2011); Suasti et al (2020)).…”

Karang merupakan ekosistem yang unik dan spesifik yang terdapat di perairan tropis, serta rentan terhadap perubahan lingkungan perairan. Penelitian ini bertujuan untuk mengetahui seberapa besar persentase tutupan terumbu karang dan indeks mortalitas terumbu karang di Perairan Pomalaa. Pengambilan data terumbu karang dilakukan pada kedalaman 3 meter untuk mewakili perairan dangkal dan 7 meter untuk mewakili perairan dalam, yang masing- masing terdiri pada 4 titik pengamatan. Parameter kualitas air yang diukur langsung di lapangan adalah, suhu, salinitas, ph, kecerahan perairan dan kecepatan arus menggunakan alat Water Quality Checker (TOAA) dan untuk analisis nitrat dan fosfat dilakukan di Laboratorium. Hasil penelitian menunjukkan bahwa kualitas perairan pada setiap stasiun penelitian tidak terdapat perbedaan yang begitu jauh. Kondisi terumbu karang di perairan Pomalaa pada kedalaman 3 m dikategorikan dalam kondisi rusak, dengan persentase penutupan karang hidup berkisar 11,85% - 22,07%. Pada kedalaman 7 m rata-rata dalam kondisi sedang-rusak, dengan persentase tutupan berada pada kisaran 16,13% - 28,81%. Hal ini menunjukkan bahwa keragaman karang secara umum rendah, sehingga tidak ada jenis karang yang mendominasi. Tingkat kematian terumbu karang di perairan Pomalaa tergolong tinggi pada kedalaman 3 meter yaitu 0,75 artinya 75% terumbu karang mengalami kondisi buruk hingga mengalami kematian, begitu pula pada kedalaman 7 meter, angka tertinggi indeks mortalitas yaitu 0,63 artinya 63% terumbu karang pada kedalaman 7 meter mengalami kondisi buruk hingga mengalami kematian.
