Abstrak: Nyungcung kampoong is least developed village, situated in Nanggung sub-district. The community of the kampoong utilized medicinal plant from its sorrounding location included forest area. For the purposes of management, spatial distribution mapping is very important. The purpose of the study is to identify the diversity and forms of utilzation as well as biophysical characteristics and accessibility. Data collection, interview and field observation were conducted in March 2015 in Nyungcung kampoong, Village Malasari, Nanggung subdistrict, Bogor. Result showed that there were 140 species of medicinal plants utilized by the community. Among the medicinal plants species family Zingiberaceae was the most predominantly utilized located in home garden and upland field. The average distance medicinal plants from the house was about 214 meters from the house situated on 600–800 meters above sea level, with gentle slope. Community utilized medicinal plants that located at its surrounding house. This is due to the fact that they have conducted domestication of the wild species from the forest. This showed that community contribute to forests conservaton.

Abstrak: Nyungcung Kampong is one of the kampong which has variety local food. The purposes of this research are to identify character of food and its utilization type. In addition, character biophysical condition and its accessibility in Nyungcung Kampong community are recorded. Data were collected by literature study, interview, and observation. The result showed that there are 155 crops species from 61 families that are utilized by the local people and most of them are from Fabaceae families. The most widely used was the fruits and tree. In comparisn with wild species, cultivated plants mostly utilized. In term of spatial distribution, the plants were found at eleveation of about 700-800 mdpl. The nearest plant distribution area was located 22.12 meters and the farest was 413.43 meter from their house.

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.
