Abstract

[Land Suitability Modeling for Fishery Resource Enhancement in the Padang Pariaman Regency, West Sumatera, Indonesia: GIS and Multi-Criteria Evaluation Approaches] Land suitability analysis is required for successful aquaculture planning. Due to the geographical setting of the Padang Pariaman Regency, aquaculture development is likely hindered by the vulnerable coastal area. Suitability assessment of aquaculture projects is crucial to specify the best method espousing sustainable development in the study area. This study aims to select the most proper location to be developed as a center of shrimp aquaculture in the Padang Pariaman Regency. This study employed the multi-criteria decision-making (MCDM), and analytical hierarchy process (AHP) approaches. This study combined the GIS-based analysis, AHP, and MCDM to yield the most proper location for aquaculture development. The three sub-models (engineering, water quality, and infrastructure) are overlaid using the weighted linear combination (WLC) technique. The infrastructure sub-model resulted in the highest coverage of highly suitable criteria with 61.74%. By contrast, the highest percentage of the unsuitable category was found in the water quality sub-model with 17.67%. Of particular concern, 87.5 % of the study area is suitable for aquaculture development. The remaining region is categorized as highly suitable with 11.93%, found in the eastern Padang Pariaman. Thus, we conclude that developing shrimp aquaculture in the study area is possible. Still, the future environmental impacts should be considered beforehand.

Abstract. Conservation Efforts of Gosong Nambi Shipwreck as an Evidence of the Past Maritime Trading Routes in Pesisir Selatan Regency, West Sumatra. The coastal region of West Sumatra has become one of the main trading routes in the 15th-19th centuries so there is no doubt that this area has many archaeological remains both underwater, coastal area, and buried underground. One of the underwater archaeological remains in this region is the discovery of a shipwreck at the Gosong Nambi coral site which is administratively located in Pesisir Selatan Regency, West Sumatra Province in 2015. This study aims to provide an overview of the current condition of the Gosong Nambi Shipwreck site. Research activities include collecting information, searching the shipwreck’s location, recording data, measuring the visible dimensions, and sketching the shipwreck, has been done. Visually, it is a small size vessel which was predicted as a cargo ship from the 1900s that might sail from Bengkulu to West Sumatra and crashed into Gosong Nambi coral (Atoll) and then sank. The shipwreck is partially buried in the sand and piles of the dead coral in the stern and most of the ship’s hull had been looted by scarp metal hunters. Natural factors also trigger site vulnerability so it is advisable to excavate. Conservation efforts are necessary to be done with a CRM approach which can have a positive impact on society on socio-economic aspects without harming any related parties. Abstrak. Wilayah pesisir Sumatra Barat menjadi salah satu jalur perdagangan utama pada abad ke-15--19 sehingga tidak diragukan lagi wilayah ini memiliki banyak tinggalan arkeologis baik yang di bawah air, wilayah pantai, maupun terkubur di bawah tanah. Salah satu tinggalan arkeologi bawah air di wilayah ini adalah temuan kapal karam di situs gugusan karang Gosong Nambi yang secara administratif terletak di Kabupaten Pesisir Selatan, Provinsi Sumatra Barat pada tahun 2015.Tujuan dari penelitian ini adalah untuk memberikan gambaran kondisi terkini situs kapal karam Gosong Nambi. Aktivitas penelitian berupa pengumpulan informasi, pencarian lokasi situs, perekaman data, pengukuran dimensi kapal yang terlihat, dan membuat sketsa kapal, telah dilakukan. Secara visual, kapal tersebut termasuk kapal kecil yang diprediksi sebagai kapal barang dari tahun 1900-an yang mungkin berlayar dari Bengkulu menuju ke Sumatra Barat dan menabrak gugusan karang (atol) Gosong Nambi dan akhirnya tenggelam. Kondisi kapal karam tersebut sebagian terkubur dalam pasir dan tumpukan karang mati pada bagian buritan dan sebagian besar lambung kapal telah dijarah oleh para pemburu besi tua. Faktor alam juga menjadi pemicu kerentanan situs sehingga disarankan untuk melakukan ekskavasi. Upaya konservasi perlu dilakukan dengan pendekatan CRM yang dapat berdampak positif terhadap masyarakat pada aspek sosial ekonomi tanpa merugikan berbagai pihak yang terkait.
