Judul: Kontribusi Sub Sektor Kehutanan terhadap Ekonomi Kabupaten Sumedang
Abstrak: Products of forestry sub-sector can be extractive and nonextractive. Sumedang district with a land area of 152,220 hectares is dominated by the agricultural sector amounted to 83.73%, including state forest lands and community forest by 36.24%. The extent of forest land allocation is an advantage for the forestry sub sector in Sumedang district. The results of the contribution analysis indicate that the forestry sub sector contributing 0.53 % - 0.73 % of GDP Sumedang district. Although a small contribution, but the forestry sub sector is a basic sector with value of LQ 3.42 - 5.76. Multiplier effect value of forestry sub sector in 2012 amounted to 45.67. This means that any additional income of Rp. Y in the forestry sub sector, resulting in additional revenue of 45.67 x Rp. Y to the total regional GDP of Sumedang district. SWOT analysis results indicate that suggested policy alternatives are to utilize the existing power to seize opportunities in the forestry sub-sector. Priority is determined using AHP method. As a result, the policy priority is the Development of Ecotourism (PE), followed by PHBM, RLK, PI.

Judul: Kontribusi Sektor Kehutanan terhadap Ekonomi Kabupaten Sukabumi
Abstrak: Conventionally, the role of forestry sector in the district of Sukabumi is indicated by its contribution to the Regional Gross Domestic Product (RGDP). However, gross value added that generated from timber industry was not taken into account. This value was included into manufacturing sector. This situation undermined the role of the forestry sector. The objectives of this study are to calculate the contribution of the forestry sector to the RGDP of Sukabumi and to determine policy alternative priority that improve forest sector contribution. The results showed the contribution of forestry sector in the period 2000 to 2011 ranged from 2.40% to 5.36%. This forestry sector is a major sector as indicated by Location Quotient value ranging from 1.05 to 1.44. The multiplier effect values varied from 41.23 to 43.05. The forestry sector was strong and had capability to realize opportunities. Therefore, the chosen strategy should support an aggressive growth policy. Expanding of collaborative and community forest management is the highest priority, followed by developing ecotourism, strengthening timber industry and rehabilitating critical land.

Judul: Transisi Fasa Materi Hadronik ke Materi Kuark pada Inti Bintang Neutron.
Abstrak: Bintang neutron terdiri dari beberapa lapisan yang disusun oleh materi nuklir yang berbeda dengan kerapatan yang semakin tinggi ketika mendekati pusat bintang. Inti luar bintang neutron disusun oleh materi hadronik (nukleon, lepton, dan hyperon), sedangkan inti dalam bintang neutron disusun oleh kuark-kuark bebas (up, down, strange) yang saling berinteraksi. Tujuan penelitian ini adalah mempelajari bagaimana transisi dari inti luar ke inti dalam bintang neutron dengan menggunakan pendekatan RMF (Relativistic Mean Field) untuk materi hadronik dan CIDDM (Confined Isospin Density Dependent Mass) untuk materi kuark. Tekanan transisi diperoleh ketika potensial kimia barion materi hadronik dan materi kuark bernilai sama. Nilai tekanan transisi dengan parameter SU6-TM1 sekitar 87 MeV/fm3 dan diperoleh massa maksimum bintang neutron yaitu 1.92M dengan jari-jari sekitar 8.62 km. Nilai tekanan transisi dengan parameter SU6-G2 sekitar 53 MeV/fm3 dan massa maksimum bintang neutron yaitu 1.88M dengan jari-jari sekitar 8.16 km. Jenis transisi fasa adalah orde satu ditandai dengan diskontinuitas dalam kerapatan energi (adanya mixed phase). Parameter-parameter pada model nuklir yang digunakan menyebabkan perbedaan kekakuan persamaan keadaan (EOS) dari materi hadronik dan materi kuark sehingga nilai tekanan transisi dari fasa hadronik ke fasa kuark juga berbeda.
