Judul: Sebaran Spasial Tumbuhan Obat yang Dimanfaatkan Masyarakat Kampung Nyungcung, Desa Malasari, Kecamatan Nanggung, Kabupaten Bogor.
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.

Judul: Penyebaran Spasial Keanekaragaman Tumbuhan Pangan dan Obat di Kampung Nyungcung, Desa Malasari, Kecamatan Nanggung, Bogor.
Abstrak: Nyungcung Kampong is situated near to the forest, in which very rich in term of plant biodiversity. The plant potentially can be utilized by the community to fulfill their need of food and medicine. The objective of the research was to identify the diversity, potency, and spatial distribution of food and medicinal plants in Nyungcung Kampong. The research was conducted by vegetation inventory and eksploration during March 2015. Result showed there was different diversity value and evenness index among every growth strata. In total, there were 318 specieses or 98 families that consist of 56 species of food plants, 112 species of food functional plants, and 150 spesies of medicinal plants. With regard to land cover/land use class, home garden had the highest number of food and medicinal plants. The plants distributed mostly on elevation of about 600--800 mdpl (308 species) or at gentle slope of about 0-8% (168 species). In addition to slope and elevation, biotic (factor caused by human) have a considerable effect in the distribution of plants. In short, the community need of necessity food and medicine can be provided by the forest and its surrounding areas.

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.
