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.

Judul: Landscape Planning of Ecotourism in Malasari Village, Mount Halimun Salak National Park
Abstrak: Indonesia memiliki 53 taman nasional yang tersebar di seluruh penjuru negeri. Taman nasional dengan tingkat biodiversitas yang tinggi di Pulau Jawa yaitu Taman Nasional Gunung Halimun Salak (TNGHS). Upaya pelestarian TNGHS dihadapkan pada beberapa masalah. Salah satu masalah yang sering terjadi adalah adanya konflik kepentingan antara masyarakat dengan pengelola taman nasional dikarenakan pelanggaran pemanfaatan lahan dan sumber daya. Konflik ini terjadi di beberapa desa, salah satunya adalah Desa Wisata Malasari yang memiliki potensi tinggi untuk dikembangkan sebagai kawasan ekowisata. Namun, kegiatan ekowisata belum memberikan keuntungan yang nyata bagi masyarakat lokal sehingga performa ekowisata Desa Malasari perlu ditingkatkan dengan perencanaan lanskap yang mengintegrasikan potensi desa yang disesuaikan dengan karakteristik lanskap desa dalam mempertahankan fungsinya sebagai wilayah konservasi taman nasional dan hutan lindung. Tujuan dari penelitian ini adalah menyusun perencanaan lanskap kawasan ekowisata Desa Malasari, Taman Nasional Gunung Halimun Salak. Perencanaan lanskap dilakukan dengan pendekatan bioregion dan Ecotourism Opportunity Spectrum (ECOS). Metode perencanaan lanskap didasari pada analisis karakteristik lanskap bioregion, potensi objek dan daya tarik ekowisata, spektrum peluang ekowisata, serta preferensi dan akseptibilitas masyarakat. Hasil penelitian berupa perencanaan lanskap ekowisata yang didasari lima prinsip ekowisata dengan menguntamakan kelestarian lingkungan serta memberi manfaat ekonomi bagi masyarakat. Perencanaan lanskap kawasan ekowisata Desa Malasari, Taman Nasional Gunung Halimun Salak menghasilkan rencana ruang, rencana aktivitas dan fasilitas, rencana sirkulasi dan ekowisata, serta rencana vegetasi., Indonesia has a total of 53 national park around the country. One with the greatest biodiversity in Java is Mount Halimun Salak National Park. Throughout the conservation programs, the national park has faced with some problems, such as conflict of interest between communities and the park manager due to some villagers that has been utilizing park’s territory and resources. One of the village with such conflict is Malasari Tourism Village which has high potential to be developed into ecotourism district. However, these ecotourism activities have not provided tangible benefit for local communities so the ecotourism performance needs improvement by landscape planning integrating potentials with landscape characteristics of the village to maintain its function as a national park and protected forest. The purpose of this research is to arrange a landscape planning for the ecotourism area of Malasari Village, Mount Halimun Salak National Park. Landscape planning is carried out using the bioregion approach and Ecotourism Opportunity Spectrum (ECOS) approach. The landscape planning method is based on the analysis of bioregion landscape characteristics, ecotourism objects and attractions, the spectrum of ecotourism opportunities, also the preferences and acceptability of the inhabitants and visitors. The research result is ecotourism landscape planning based on five ecotourism principles prioritizing in environmental sustainability and providing economic benefits to the community. The landscape planning of ecotourism in Malasari Village, Mount Halimun Salak National Park produces spatial plans, activity and facility plans, circulation and ecotourism plans, and vegetation plans.

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.
