Judul: Hubungan Antara Sistem Sosial Ekologi Petani Salak Pondoh dan Penyenggrong
Abstrak: Berdasarkan penelitian pendahuluan didapatkan kesenjangan ekonomi antara sistem sosial ekologi petani salak pondoh dan sistem sosial ekologi penyenggrong (penambang pasir) . Hal ini nampak dari harta kepemilikan mereka dan yang lebih rentan adalah pada penyenggrong. Perbedaan ini mempengaruhi pola hidup, aktivitas, pranata sosial, dan persepsi mereka terhadap lingkungan. Tujuan penelitian ingin mengetahui hubungan antara dua sistem sosial tersebut. Lebih jauh penelitian ini ingin melihat seberapa besar kontribusi kebuncampur dalam pengentasan kemiskinan.

Judul: Perhutanan Sosial dan Langgengnya Ketimpangan Penguasaan Lahan Hutan
Abstrak: Hutan merupakan kesatuan ekosistem yang vital perannya bagi masyarakat sekitar hutan. Dalam upaya mengurangi ketimpangan penguasaan, pemerintah melegalisasi penguasaan yang dilakukan oleh masyarakat di wilayah kerja Perhutani dengan Perhutanan Sosial skema IPHPS. Peraturan tersebut merubah sistem tenurial yang telah ada dan menciptakan kapital-kapital dalam lapisan sosial pada masyarakat. Penelitian ini bertujuan untuk menganalisis hubungan sistem tenurial pasca Perhutanan Sosial IPHPS dengan stratifikasi sosial baru dalam masyarakat serta implementasi Perhutanan Sosial dengan skema IPHPS mengubah sistem tenurial yang mengarah pada pemerataan dan keadilan agraria. Lokasi penelitian ini yaitu Dusun Patrol, Desa Dano, Kecamatan Leles, Kabupaten Garut. Metode yang digunakan ialah metode survei dengan pendekatan kuantitatif dengan kuesioner dan didukung data kualitatif dengan teknik wawancara mendalam. Pengambilan sampel dilakukan dengan teknik accidental sampling dan snowball. Data dianalisis menggunakan uji korelasi Rank Spearman dan uji Paired T-test. Hasil penelitian menunjukkan bahwa terdapat hubungan yang lemah diantara sistem tenurial pasca Perhutanan Sosial dengan stratifikasi sosial yaitu dengan P-value dari korelasi 0,048 dan nilai koefiesien Rank Spearman sebesar 0.261. Adapun perubahan sistem tenurial pasca Perhutanan Sosial meliputi penguasan lahan yang lebih luas oleh elit petani, durasi penguasaan yang diperpanjang, penguasaan moda produksi lebih dimiliki oleh elit, dan menurunnya intensitas relasi dengan Perhutani.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
