Abstrak Penelitian bahaya abrasi Pantai Surantih dilakukan di Kecamatan Sutera Kabupaten Pesisir Selatan dengan tujuan mengetahui tipologi pantai daerah penelitian dan menganalisis bahaya abrasi pantai daerah penelitian. Metode yang digunakan adalah metode survei dan metode pengharkatan pada setiap veriabel yang mempengaruhi bahaya abrasi pantai. Metode survei dilakukan untuk pengamatan langsung di lapangan serta melakukan pengukuran terhadap karakteristik karakteristik gelombang dan pengambilan sampel untuk dianalisis di laboratoium. Hasil analisis data lapangan dan data laboratorium ditabulasikan untuk menentukan tingkat bahaya abrasi. Hasil tabulasi data lapangan dan data laboratorium ini dimasukan ke dalam perangkat lunak komputer dalam bentuk software Arc GIS 10.23, hasil keluaran berupa peta bahaya abrasi daerah penelitian. Hasil penelitian menunjukkan bahwa daerah penelitian memiliki tipologi pantai yang seragam yaitu tipologi pantai berpasir (pantai bergisik). Tipologi pantai ini disebabkan oleh material penyusun pantainya berupa pasir kasar hingga pasir halus yang bersumber dari daratan dan sebagian kecil berasal dari lautan yaitu berupa rombakan karang. Sebagian besar material penyusun tipologi pantai berpasir berupa material yang merupakan hasil erosi pada bagian hulu (upper lands) yang dibawa oleh Batang Surantih ke pantai kemudian diendapan pada lingkungan pantai. Bahaya abrasi Pantai Surantih pada saat ini tergolong tinggi karena material penyusun pantainya berupa pasir yang berasal dari daratan ataupun hasil rombakan karang di laut. Pada saat penelitian dilakukan Pantai Surantih sedang mengalami akresi atau daerah pantainya sedang mengalami penambahan dan dalam kondisi equilibrium dynamic atau pantai dalam kondisi seimbang yaitu material yang terabrasi dan proses sedimentasi pada lingkungan pantai hampir sama, sehingga menyebabkan pantai tidak bertambah dan tidak berkurang (pantai dalam kondisi stabil).

Abstrak Penelitian transportasi sedimen pantai daerah Pulau Karam dilakukan di Kecamatan Sutera Kabupaten Pesisir Selatan dengan tujuan mengetahui karakteristik gelombang dan transportasi sedimen pantai pada daerah penelitian. Metode yang digunakan adalah metode survei pada setiap veriabel yang mempengaruhi transportasi sedimen pantai. Metode survei dilakukan untuk pengamatan langsung di lapangan serta melakukan pengukuran terhadap karakteristik gelombang dan pengambilan sampel sedimen untuk dianalisis di laboratoium. Hasil analisis data lapangan dan data laboratorium ditabulasikan untuk menentukan transportasi sedimen pantai. Hasil penelitian menunjukkan bahwa karateristik gelombang pada daerah penelitian berupa tinggi gelombang, panjang gelombang, periode gelombang, kecepatan gelombang, energi gelombang, dan tinggi hempasan gelombang. Tinggi gelombang pada daerah penelitian berkisar antara 0,13 – 0,92 m, periode gelombang berkisar antara 5 dt– 15 dt, panjang gelombang berkisar antaa 39 m - 156 m, kecepatan gelombang berkisar antara 7,80 m/dt – 23,40 m/dt, energi gelombang antara 0,038 kg/s2 – 1,6 kg/s2, dan tinggi hempasan gelombang ke pantai antara 0,03 m – 1, 86 m. Transportasi sedimen pantai pada daerah penelitian menunjukkan penyebaran yang tidak merata, umumnya sedimen pantai yang memiliki ukuran lebih besar akan diendapkan dekat muara sungai dan material sedimenyang berukuran halus akan diendapkan lebih jauh dari muara sungai. Material sedimen pantai pada daerah penelitan mulai dai pasir halus, pasir kasar dan kerikil. Transportasi sedimen pantai daerah penelitian dapat dilihat dari nilai d50 sedimen pantai yaitu0,222 mm – 0,753 mm, dan transportasi sedimen pantai berkisar 0,1 m3/hr – 603,98 m3/hr. Transportasi sedimen pantai dipengaruhi oleh arus sejajar pantai (longshore current) aitu 0,02 m/dt – 6,79 m/dt.

Land over function is a change in the function of some or all land areas of the original function (as planned) into another function. These changes have a negative impact (problems) on the environment and potential of the land itself. One of these changes took place in West Pasaman Regency, especially on wet farms (rice fields) into oil palm plantations. It makes the production of rice fields decrease, and has an impact on the availability of rice for society. This research aims to see how much rice production is and how the availability of food (rice) for the community in the district of Luhak Nan Duo, West Pasaman Regency. Therefore, the availability of food, especially rice in the district of Luhak Nan Duo can be fulfilled and assured for the long term. This research uses a quantitative descriptive method which provide a real potrait of the variables obtained to get the real situation. The variables in this study are, land area, amount of rice production, number of inhabitants, and the rice needed percapita. The data collection techniques are, study document to find the population of the residents, interviewing the farmer to know how rice paddy management, and observation to find out the area of existing rice fields. The method of the data analize is using descriptive quantitative. The result of the research shows that the production of the rice in Luhak Nan Duo increased. But it has not fulfilled the needs of the residents in Luhak Nan Duo. It means that Luhak Nan Duo has not self-sufficient in rice yet.
