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: Desain Lanskap Bantaran Sungai Ciliwung Berbasis Ekologi di Kawasan Permukiman Kelurahan Pejaten Timur, Kota Jakarta Selatan
Abstrak: Jakarta merupakan kota yang memiliki jumlah penduduk cukup padat dan terus bertambah setiap tahunnya. Peningkatan jumlah penududuk yang pesat menimbulkan kurang selarasnya antara kebutuhan lahan untuk tempat tinggal dan ketersediaan lahan yang ada. Kondisi tersebut mendorong terjadinya perubahan fungsi lahan bantaran sungai menjadi pemukiman pada bantaran sungai seperti yang terjadi di Kelurahan Pejaten Timur, Jakarta Selatan. Pemukiman yang ada pada bantaran sungai tersebut kemudian menimbulkan masalah lingkungan berupa penyempitan lebar sungai dan juga pencemaran sungai. Keadaan tersebut menyebabkan daerah ini sering dilanda banjir setiap musim hujan datang. Penelitian ini dilakukan dengan tujuan mendesain bantaran Sungai Ciliwung dengan mengembalikan fungsi bantaran sungai yang sesuai sebagai ruang terbuka hijau. Ruang terbuka hijau yang didesain berupa taman kelurahan yang dapat digunakan sebagai daerah resapan air, meningkatkan fungsi ekologis bantaran sungai, dan sebagai tempat bersantai bagi penghuni permukiman di sekitar tapak. Desain bantaran Sungai Ciliwung dilakukan dengan metode proses desain menurut Booth (1983) yang terdiri dari persiapan, inventarisasi, analisis, sintesis, dan desain tapak. Pada bagian analisis ditentukan potensi dan kendala tapak sehingga dapat dihasilkan rencana pengembangan tapak yang sesuai. Konsep yang diterapkan adalah “Eco-relaxing riverside park”, yaitu taman kelurahan di tepi sungai yang ramah lingkungan dan memiliki fungsi utama sebagai tempat bersantai bagi pengunjung. Di dalam taman terdapat berbagai fasilitas publik yang dapat digunakan oleh pengguna untuk beraktivitas dengan nyaman di dalamnya, seperti menikmati pemandangan, bersantai, bermain, berolahraga, dan berinteraksi sosial. Desain taman kelurahan yang dihasilkan diharapkan dapat meningkatkan nilai fungsional dan estetika bantaran Sungai Ciliwung di Pejaten Timur, Jakarta Selatan. Hasil akhir dari penelitian ini adalah site plan, perspektif keseluruhan, perspektif spot, gambar potongan tampak, gambar detail, serta penjelasan mengenai gambargambar tersebut.

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.
