Judul: Perencanaan lanskap ekowisata Pulau Berhala Serdang Bedagai Provinsi Sumatera Utara
Abstrak: Berhala Island is one of the 92 outermost small islands in Indonesia. The island has an area about 44.75 Ha and coastline about 700 m. There are five natural objects of tourism that exist on this island which are the beach, tombolo, Sokong Nenek Island, Sokong Siembang Island, and the jungle of the island. These objects have very potential to support the concept of eco-marine tourism which has been set by the Government of Serdang Bedagai regency. The observation method of this research will be done by observing some aspects such as legal, biophysical, tourism, and social aspects. Concept for the planning is to create an island that can maintain environmental sustainability, participatory, and educational. Site zoning is divided in two zones, zone of tourist utilization at 22.55% and conservation zone at 77.45%. Main area is used for tourism while conservation spaces just as protection area.

Abstrak: This research was located in South Morotai and South-West Morotai District.The objectives of this researchis to study carrying capacity and to establish model concept management small islands for ecotourisms sustainable used. Data and information were collected in participative term by used a questioner and field survey. Analysis methods consist of spatial analysis used geographycal information system and suitable area analysis, for modelling used software Stella 9,02. The small island areas zonation using ecology, economic, social and institution criterias could be divided into 3 management zones such as the center zone with of 1618 ha, used zone with widely of 12.412 ha, and buffer zone with widely of 32.381 ha. Whereas suitable area for ecotourism zone consist of coastal ecotourism for recreation tourism categories, marine ecotourism categories for snorcling tourism, marine ecotourism categories for diving tourism, marine ecotourism category for seagrass. Shore longs of recreation tourism 59.809 m with of carrying capacity is 2.353 person/day, snorcling tourism with widely area used 226 ha with percentage rate of coral cover community 42 % with of carrying capacity 7.624 person/day, diving tourism with widely area 1.248 ha with percentage rate of coral cover community 40% with of carrying capacity 39.942 person/day, seagrass tourism with widely area used 102 ha with percentage rate of seagrass cover 58 % with of carrying capacity 4.733 person/day. Management model KP2K MS2B for ecotourism sustainability base on environmental conservation of ecologycal small island with the primary point were archipelago small island, integration in percentage pattern of the diversity used rate and the naturalism of island, if the invironmental ecological was disturbed, it will influence the sustainability of carrying capacity and the ecotourisms demand will affected too.

Judul: Apatite Growth Optimation on Chicken Mucouse by Fourier Transform Infrared (FTIR) Characterization
Abstrak: Some experiment had been conducted to grow apatite from supersaturated solution of calcium phosphate ions on chicken mucouse. The calcium and phosphate ions were originated from Ca(NO3)2 and (NH4)2HPO4. Carbonate ions from (NH4)2CO3 was also used as starting solution. Experiment was carried out within about 5 hours at temperature 370 C and pH 7. Value of Ca+ : PO4 3- was 1.67, while molar ratio of CO3 2- : PO4 3- was 0.5 : 1. Molarity of molar ratio CO3 2- : PO4 3- variated approximately 0.15 : 0.30, 0.51 : 1.02, and 0.90 : 1.80. Mass of mucouse powder was constant 0.75 gram. The analysis result of Fourier Transform Infrared (FTIR) showed that the precipitation was apatite carbonate type A and B. In these experiment it was found out that the mucouse reduce the crystallinity of apatite precipitant, and the growth of apatite crystal was optimum at solution with molar ratio CO3 2- : PO4 3- about 0.15 : 0.30.
