Judul: Perencanaan Lanskap Situ Rawa Kelapa Dua Wetan, Ciracas, Jakarta Timur
Abstrak: In landscape, water was one of the decisive element of a shape and function. Water was also a natural resource which had a very important function for living creatures. Lake was a natural resource that almost forgotten. The main function was as buffer zone, water catchment areas and prevention of natural disasters such as floods, especially in big city like Jakarta. Protection and management of lake had less attention. Kelapa Dua Wetan Bog Lake have an area 8.40 ha and serves as a catchment area, reservoir, and rain water control in East Jakarta by KDB 20% based RUTR Jakarta. Physical condition of the waters were blue-black, slightly smelly, and the contaminated medium. The lake experienced siltation, narrowing, and loss due to switching function. Population pressure and the shifted- land exacerbated existing environmental conditions. The lake managed by local government in East Jakarta who planned to expand the acreage lake of the 8 to 11 Ha. Every month there was janitor of the Irrigation Department to clean up the environment around it. The basic concept in planning Kelapa Dua Wetan Bog Lake was refers to the return of the initial function of the lake as water catchment areas and flood buffer. It could be sustained existence and preservation also sustainability in the future. Landscape planning of Kelapa Dua Wetan Bog Lake as water catchment areas included spatial plan, green plan, circulation plan, landscape plan, and plan programs. The spatial planning was divided into three spaces with the main function was to restore the ecological function. Program plan aimed to support regional landscape plan of Kelapa Dua Wetan Bog Lake that addressed to people, because plan couldn’t come to fruition without the support and participation of surrounding communities.

Judul: Landscape Design Situ Jatijajar as Water Tourism Area of Depok City
Abstrak: Danau adalah salah satu lahan basah dengan sistem airnya yang tergenang. Air dalam danau alami atau buatan dapat digunakan untuk kebutuhan manusia dan berbagai macam keperluan hidup manusia. Salah satunya dapat menjadi tujuan rekreasi, dimana keperluan ini dibutuhkan untuk menyegarkan fisik maupun mental manusia. Terdapat beberapa kota yang memiliki fungsi sebagai kota tangkapan air. Kota Depok sebagai salah satunya difasilitasi oleh banyaknya danau dan badan air yang membuat kota ini cocok untuk menjadi kota tangkapan air. Penelitian ini bertujuan untuk menganalisa dan mengembangkan potensi wisata air sehingga dapat membentuk kawasan wisata air yang mempertahankan kondisi sosial dan ekologi lingkungan. Hasil penelitian ini memberikan rekomendasi kepada pemerintah dan pengelola terkait mengenai perancangan kawasan tersebut sebagai wisata air yang sesuai dengan kondisi sosial dan lingkungan. Konsep dasar penelitian adalah sustainable tourism yaitu konsep pengembangan kawasan dengan memperhatikan kondisi lingkungan dan menunjang potensi aktivitas pariwisata. Pemilihan material dan desain fasilitas berbasis pada gambaran pohon jati secara natural dan organik. Hasil penelitian berupa rancangan kawasan yang terbagi menjadi area budidaya, area konservasi, area pelayanan, area penerimaan, area rekreasi serta area wisata dan edukasi yang menunjang berbagai aktivitas dan kebutuhan pengunjung tetapi tetap menjamin batasan konservasi kawasan. Area wisata dan edukasi sebagai area utama kawasan menunjang aktivitas mengelilingi situ menaiki sepeda air atau perahu naga dan menjelajah hutan jati atau melihat pemandangan di menara observasi, Lake is one of the wetlands with its stagnant water system. Water in either natural or artificial lakes can be used for human needs and various purposes of human life. One of them can be a recreational purpose, where this necessity is needed humans to refresh physically and mentally. Several activities have the function of Water Catchment City. Depok City is one of them facilitated by the existence of many lakes and water body that makes suitable as the Water Catchment City. This study intended to analyze and develop the area-based potential of water tourism so that formed a water tourism area that considers the social and ecological condition of the environment. The result of this study provides recommendations for the government and related managers on the design of the area as suitable for water tourism and by social and environmental conditions. The basic concept of the study is Sustainable Tourism, the concept of regional development by taking account of environmental conditions and supporting potential tourism activities. Material selection and facility design are based on the natural and organic image of the teak tree. The result of the study is design which is divided into cultivation area, conservation area, service area, reception area, recreation area as well as tourist and educational area that support various activities and visitor needs but still guarantee the boundaries of area conservation. The tourist and educational area as the main supports activities such as around the lake with water bike or dragon boat and exploring the teak forest and seeing the scenery at the observation tower.

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.
