Judul: Perencanaan Partisipatif Pemanfaatan Taman Wisata Alam Buluhcina, (Kasus di Desa BuIuhcina, Kecamatan Siak BuIu Kabupaten Kampar, Provinsi Riau)
Abstrak: Buluh Cina Natural Park in Kampar District, Riau Province was initially Indigenous Forest (Hutan Adat) of Rimbo Tujuh Danau which has an area about 2.500 ha. Later, based on Governor Decree of Riau Province in 2007, most of the forest area used as a Natural Park area about 1,000 ha. Buluh Cina Natural Park have not been managed yet completely, but commonly it utilized by the communities to fulfill their daily needs. This study aims to determine the uses of forests and map the location of the utilization, furthermore describing the suitability of forest use practices with laws and regulations, as well as the use of participatory plan. This study, using data that obtained through multiple methods of data collection, which are review of secondary data, direct observation, interviews, focus group discussions (FGD) and mapping of areas. The results of this research show that Buluh Cina Natural Park utilization does not match with the provisions of existing law. The results of participatory planning which lead to the type of utilization that does not exploitative but the public has greater accessibility to forest management.

Abstrak: Forest displace function in Cirompang Village from production forest become conservation forest generates polemic to community. Community accessibility to forest is also closed although it cannot be completely done until now. Forbidden access to the forest doesn’t decrease level of forest management because community finally realizes that the damage of forest is also their loss so that they decide to preserve nature using their own rule in area which they can manage by themselves. Government decision to make forest in Cirompang Village as conservation area will harm community. If it is closed, farmer will lose their farm area which large is a half from Cirompang village. This will be effected their income although there are others factors that influence their income, like their earnings from SPPT and from another sector besides agriculture. Participative mapping is selected to solve the problems of village area system. Participative map that contains boundary system and farm system can prove that they can manage their farm with their own mores without ignoring preservation of the nature.

Judul: Kajian Mekanisme Transport Ion pada Membran Telur Ayam Ras melalui Pengukuran Listrik
Abstrak: Telah dilakukan penelitian untuk mengetahui mekanisme transport ion yang melewati membran telur ayam berdasarkan pengukuran sifat kelistrikan membran dengan meninjau pengaruh dari konsentrasi, valensi ion, suhu dan frekuensi. Sifat kelistrikan dapat dilihat dengan melakukan pengukuran tegangan, konduktansi, dan karakteristik 1-V. Pengukuran dilakukan dengan menggunakan dua metode yaitu tanpa pemberian sumber arus eksternal dan dengan pemberian sumber arus eksternal. Pengukuran tanpa pemberian sumber arus eksternal digunakan untuk menentukan nilai tegangan membran pasif. Sedangkan, pengukuran dengan pemberian sumber arus eksternal digunakan untuk menentukan nilai konduktansi listrik dan karakteristik I-V membran. Penentuan tegangan, konduktansi dan karakteristik I-V membran dilakukan dengan cara meletakkan membran di dalam chamber yang diisi larutan elektrolit NaCl, MgCl2 dan AlCl3. Variasi konsentrasi, valensi ion, suhu dan frekuensi mempengaruhi nilai tegangan, konduktansi dan karakteristik I-V membran. Semakin besar konsentrasi dan suhu larutan eksternal maka tegangan, konduktansi dan kemiringan I-V membran meningkat. Ditinjau dari valensi ionnya maka tegangan dan konduktansi listrik membran terbesar ditunjukkan oleh larutan AlCl3. Konduktansi listrik membran akan meningkat dengan meningkatnya frekuensi larutan eksternal. Karakteristik I-V membran telur mendekati sifat ohmik. Pengaruh variasi suhu pada larutan NaCl konsentrasi 0,1 mM dan 10 mM serta larutan MgCl2 dan AlCl3 konsentrasi 0,1 mM tidak memberikan kontribusi yang signifikan terhadap aliran arus. Pengaruh variasi suhu terhadap kemiringan kurva I-V terlihat pada konsentrasi NaCl 100 mM, sedangkan MgCl2 dan AlCl3 pada konsentrasi 10 mM dan 100 mM.
