The present study on beach morphology and its profile dynamics was carried out to categorize the morphodynamic classification of selected beaches in Pahang, comprising the areas from Teluk Chempedak to Kuala Pahang. Beach stations were monitored monthly for a complete 1-year cycle; beginning from February 2012 to February 2013 at 12 corresponding stations established at random morphological intervals. Based on the results obtained, which include the granulometric analysis and beach surface topography, three main beach classes have been differentiated: reflective, intermediate and dissipative beaches. The reflective beaches exhibits rather high degree beach slopes and coarse-grain sand sizes compared to intermediate and dissipative classes.

A study was carried out around the lagoon and coastal area of Setiu wetlands to determine the general characteristics and grain-size distribution of their sediments. Sediment samples were collected from 39 stations of the lagoon area and 8 stations of the coastal area, and were analyzed for their sedimentological characteristics (mean, sorting, skewness and kurtosis). The sediment mean size ranged between 0.06-2.52 and 2.12-2.69 phi (Ø) for both lagoon and coastal sea-bottom sediments, respectively. Generally, the sediments in the study area consist mostly of coarse to fine particles. The major portions of the sediment are negatively skewed. This indicates that the study area is under the influence of the rather strong wave and current action. The study also encompassed the geophysical survey that was conducted near the coastal zone of the study area. The high-resolution seismic sub-bottom profiling technique is the standard method employed to map geological features and locate structures below the surface of the seafloor. Data obtained from seismic records were used to interpret the seismic reflectors. Three main reflectors (layers), which consist of the seabed and the seabed multiple, were traced using Sonar Web Pro software, and the results showed a uniform distribution pattern for all stations surveyed. It is envisaged that this method could be an effective way to image the marine subsurface structures; thus, its use is anticipated in the higher degrees of sedimentary research and marine resource exploration.

Abstrak. Pemanfaatan tikar pandan duri, dan gula aren, di Desa Remukut sudah berlangsung sejak lama dan diwariskan turun temurun. Tujuan penelitian ini adalah untuk mengidentifikasi jenis-jenis hasil produk hasil hutan bukan kayu berupa tikar pandan duri dan gula aren, selain itu untuk mengetahui nilai ekonominya. Sampel dalam penelitian ini sebanyak 19 kepala keluarga yang memanfaatkannya. Produk hutan bukan kayu yang dimanfaatkan berupa pandan duri yang diolah menjadi tikar, dan aren yang diambil niranya kemudian diolah menjadi gula. Berikut ini nilai ekonomi dari setiap produk per tahun, yaitu: tikar pandan duri sebesar Rp. 74.800.000, dan gula aren Rp. 37.310.000. Hasil per tahun memiliki nilai ekonomi sebesar Rp. 112.110.000 dengan rata-rata penghasilan per kepala keluarga dalam satu tahun adalah Rp. 5.900.526. The Economi Value of Some Untilization of Non-Timber Forest Products on the Income of the Remukut Village Community Pantan Weather District Gayo Lues RegencyAbstract. The use of thorn pandan mats and palm sugar in Remukut Village has been going on for a long time and has been passed down from generation to generation. The purpose of this study was to identify the types of non-timber forest products in the form of pandanus thorn mats and palm sugar, in addition to knowing their economic value. The sample in this study were 19 heads of families who used it. Non-timber forest products used are pandanus thorns which are processed into mats, and sugar palm which is taken from the juice and then processed into sugar. The following is the economic value of each product per year, namely: pandan thorn mats of Rp. 74.800.000, and palm sugar Rp. 37,310,000. The yield per year has an economic value of Rp. 112.110,000 with an average income per head of family in one year is Rp. 5,900,526.
