Abstrak: The relationship between human and their environment, especially related to the use of plants known as ethnobotany. Plants utilization by local communities that based on local culture produced typical knowledge known as traditional knowledge. A change in lifestyle of a society can threaten the existence of traditional knowledge held by the community. This study aimed to determine the type of plants utilization and traditional knowledge in the form of plants used by communities in the surrounding area of Gunung Simpang Nature Reserve. This research was conducted at Miduana Hamlet, Balegede Village, Naringgul Subdistrict, Cianjur Regency, West Java in January, February, and May 2010. Tools and materials used in this study include questionnaires, digital camera, transparent plastic size 40x60 cm, newspapers, hanging labels, plant identification books, alcohol 70%, the data area of Gunung Simpang Nature Reserve, and demography of Balegede Village, while the object was Miduana Hamlet’s community and surrounding vegetation. Data collected include primary and secondary data. Primary data included the data of plants used by the respondents.

Data analysis was performed by classifying the use of plants to 13 groups of usage, calculating the percentage of habitus and the percentage of parts used, and analyzes preference ranking and use value. The communities of Miduana Hamlet used 191 plant species from 69 families that classified into 13 group of usage. They used 62 species for food, 74 species for medicinal purpose, 43 species for ornament purpose, 19 species for indigenous utility, 14 species for building materials, 12 species for cattle feeding, 12 species for aromatic purpose, 9 species for firewood, 14 species for ropes, wickerwork, and crafts, 4 species for dyes, 4 species to exceed pest, 4 species for beverage, and other uses as many as 7 species.

Judul: Pengaruh pengeceran lateks karet terhadap karet sir 5L yang di hasilkan
Abstrak: Penelitian ini dilakukan untuk mengetahui pengaruh pengenceran lateks sampai tingkat kadar karet kering (KKK) tertentu yang diperbolehkan untuk menghasilkan mutu karet SIR 5L yang lebih baik dari standar, atau untuk mengetahui perlu atau tidaknya melakukan pengenceran lateks dalam menghasilkan karet dengan mutu SIR 5L. Perlakuan yang diberikan adalah pengenceran lateks dengan 6 taraf pengenceran, yaitu A1 (KKK 27 persen), A2 (KKK 24 persen), A3 (KKK 21 persen), A (KKK 18 persen), A5 (KKK 15 persen) dan Ag (KKK 12 persen). Faktor mutu yang dianalisa adalah warna karet, kadar abu, kadar zat menguap, kadar kotoran, nilai plastisitas awal (Po) dan nilai PRI (Plasticity Retention Index). Pengenceran lateks memberikan perbedaan yang sangat nyata terhadap nilai warna karet, kadar abu karet, kadar kotoran karet dan nilai Po karet. Tetapi tidak memberikan perbedaan terhadap nilai PRI karet dan kadar zat menguap. Pengenceran lateks sampai KKK 12 persen memberikan spesifikasi mutu yang paling rendah, kecuali spesifikasi Po. Pengenceran lateks sampai KKK 24 persen memberikan nilai Po yang masih tinggi, tetapi pengenceran lateks di bawah KKK 24 persen akan menurunkan nilai Po karet.
