"ABSTRACTRobert Louis Stevenson, who is well known for treasure island (1883) and strange case of Dr Jekyll and Mr Hyde (1886), ws born in a family engaged in linghthouse engineering for generations. Under the Influence of his family business, the sea had been familiar to the scottish writer since his childhood although he did not succeed it. For This reason, it is no wonder that he should foreground the sea as the main setting in some of his works."

"Kenaikan muka air laut sebagai dampak fenomena pemanasan global telah mengakibatkan terjadinya perubahan garis pantai di seluruh dunia, didalamnya termasuk pesisir Madura yang merupakan sentra produksi garam nasional. Penelitian ini mengkaji perubahan garis pantai dan wilayah yang berpotensi sebagai tambak garam di pesisir selatan Kabupaten Pamekasan. Variabel pengunaan lahan, kemerengan lereng, ketinggian tempat, kenaikan muka air laut dan letak garis pantai secara time series kedua masalah yang diteliti. Informasi spasial ketinggian dengan interval 1 meter diperoleh dengan menggunakan metode ANUDEM berbasis citra Quicbird. Analisisi overlay citra Iqonos 2006 dengan citra Quikbird 2014 menemukan bahwa wilayah pantai yang berubah terletak di Kecamatan Pademawu. Analisis peta yang didasarkan pada scenario kenaikan muka air laut yang di keluarkan IPCC diperoleh wilayah yang berpotensi sebagai area tambak garam baru terletak di Kecamatan Pademawu.

Sea level rise as an impact of global warming phenomenon has changed shoreline around the world, including Madura shoreline that happen to be central of national salt production. This research tries to examine the changes in coastline environment and to find a potential area for salt pond in south Pamekasan Regency. Land use, slope, altitude, sea level rise and shoreline in time series used as variables to examine that problems. Spatial information for coastal altitude in interval 1 meter range was obtained bay using AMUDEM method based of Quickbird imagery of 1 meter intervals obtained using the method based ANUDEM QuickBird imagery. Overlay analysis from Iqonos imagery in 2006 and Quickbird imagery in 2014 found that from over south coastal area in Pamekasan, Pademawu shoreline is the only one that changes. Analysis based on topographic map and scenario from IPCC found that the most potential area in Pamekasan to be salt pond located in Pademawu District. "

"Kadar air dan kadar garam merupakan beberapa parameter yang digunakan untuk memprediksi tingkat kualitas teripang pasir kering (Holothuria scabra) atau yang dikenal Bêche-de-mer. Namun, pengukuran kadar air dan garam umumnya bersifat destruktif dan dilakukan secara manual melalui uji laboratorium sehingga memakan waktu yang lama. Dalam penelitian ini, sistem pengukuran yang dikembangkan untuk memprediksi kualitas teripang pasir kering adalah sistem pengukuran yang berbasis citra Visible Near-Infrared (V-NIR) yang mampu mengukur kadar air dan garam secara non-destruktif. Algoritma partial least squares regression (PLSR) digunakan untuk membangun model prediksi pada data spektral. Sistem pengukuran untuk kadar air dan garam di evaluasi dengan koefisien korelasi untuk data pelatihan sebesar 0,99 dan 0,99 secara berurutan. Sedangkan untuk root mean square error dari kadar air dan garam adalah 0,92 dan 0,11. Hasil penelitian ini menunjukkan bahwa sistem ini dapat diusulkan sebagai sistem pengukuran kadar air dan garam secara non-destruktif untuk menguji kualitas pada teripang pasir kering (Holothuria scabra) dan dapat diimplementasikan sebagai sistem penyortiran di dunia industri.

Water content and salt Content are parameters used to predict the quality level of dried sea cucumber (Holothuria scabra) or known by Beche-de-mer. However, Measurements of moisture content and salt content are generally conductive and carried out manually through laboratory tests so that it takes a long time. In this study, a measurement system developed to predict the quality of dried sea cucumber is a valid system for Visible-Near Infrared (V-NIR) images based on the spectral reflectance characteristics of the moisture content and salt content to predict non-destructively the values ​​of the moisture and salt content. The partial least squares regression (PLSR) algorithm is used to build prediction models on spectral data. Predictive system models are used to obtain moisture and salt values. The predicted results are compared with the results of measurements of data references obtained using the laboratory test. The measurement prediction system for moisture and salt content has a correlation coefficient for test data 0,99 and 0,99 respectively. While for the root mean square error of the water and salt levels are 0,92 and 0,11. The results of this study indicate that this system can be proposed as a non-destructive system of measuring moisture and salt content to test the quality of dried sea cucumbers (Holothuria scabra) and is suitable for implementation in sorting systems in the industrial world"
