Judul: Potensi dan Pemanfaatan Tumbuhan Berguna Di Cagar Alam Bojonglarang Jayanti Kabupaten Cianjur Jawa Barat
Abstrak: Bojonglarang Jayanti Nature Reserve is a protected area which has various ecosystem including lowland forest, and land processed forest. This research purposes are to identify the potency of useful plant and the utilized plants by the local people. The methode of research wash conducted by vegetation analysis and snowball sampling technik for interview. The calculation of vegetation analysis in every forest formation has the diversity index > 1,5 and evenness > 0,5 in every growth level. The vegetation analysis of useful plant potency wich is ±83% identified or 128 species from 154 species that belong into 57 families. People utilization of herb, there are 130 species that belong into 51 families. Mostly those plants are utilized as medicine, housing material, and food.

Judul: Etnobotani dan potensi tumbuhan berguna di Taman Nasional Gunung Ciremai, Jawa Barat
Abstrak: The people around TNGC have a very close interaction with the surrounding natural resources as can be seen when they deal with the use of plants (ethnobotany). Documenting the people‟s knowledge in TNGC ethnobotany is especially important so that the knowledge of TNGC people in the use of these plants can be preserved. This study aimed to identify the use of plants by the people around TNGC (etnobotany) and to find out the potential of useful plants in the TNGC region. Ethnobotany study was conducted by interviews and the potential of useful plants in the TNGC region was learned through a vegetation analysis. The number of species obtained from the ethnobotany results was 131 species and 62 families. Medicinal plants were among the much used reaching 37 species. The number of spesies obtained from the results of vegetation analysis was 99 plant spesies and 43 families residing in the TNGC area. The most useful plant species were plants producing buildings as many as 14 species. Out of 131 plant that were used by community, many them were not be found in the area of TNGC reached 113 species, whereas plants that were aas many as 18 species. Of all the plants obtained from the ethnobotany results and vegetation analysis, 10 superior species can be develoved by communities around the TNGC area, for example, nilam (Pogostemon cablin) as aromatic material and raw material for the manufacture of perfume and ground orchids with yellow flowers (Phaius flavus ) for ornamental plants. These superior species if well-cultivated are expected to help TNGC community improve their income.

Judul: Pelapisan hidroksiapatit (HAp) pada permukaan logam Stainless Steel 316L dengan metode deposisi elektroforesis (EPD)
Abstrak: Telah dilakukan penelitian untuk melapisi permukaan logam stainless steel 316 L. oleh material hidroksiapatit dengan metode deposisi elektroforesis. Hidrokiapatit dibuat dengan metode presipitasi, dari hasil kalsinasi cangkang telur pada suhu 1000°C selama 5 jam dan (NH4)2HPO4- Pemilihan logam stainless steel (SS) didasarkan pada sifat ketahanan korosi yang baik, kadar impuritas rendah, dan mudah dibentuk. Penelitian dilakukan dengan melarutkan hidroksiapatit pada etanol ditambah trietanolamin sebagai dispersan. Konsentrasi Ca/ P yang digunakan pada saat presipitasi yaitu 0,3/0,16. Spektra infra merah menunjukkan hilangnya karbonat pada sampel hasil presipitasi yang dipanaskan pada suhu 900°C. Pola difraksi sinar X untuk hasil presipitasi yang dipanaskan pada suhu 900°C, menunjukkan fasa yang terbentuk adalah hidroksiapatit. Pola difraksi setelah coating menunujukkan adanya fasa hidroksiapatit dan base metal yaitu logam SS. Hasil uji mikrostruktur menunjukkan, diantara penggunaan variabel tegangan 30 V; 60 V dan 90 V selama 1, 2, dan 3 menit pada saat coating, penggunaan variabel tegangan 60 V selama 2 menit, menunjukkan hasil pelapisan yang paling merata pada permukaan logam SS. Sintering dengan suhu 800°C lebih menguatkan pelapisan hidroksiapatit pada permukaan logam dibandingkan dengan sintering pada suhu 250°C.
