Judul: Dampak Perluasan Taman Nasional Gunung Gede Pangrango terhadap Pola Penguasaan Lahan dan Struktur Nafkah (Kasus Rumah Tangga Petani Desa Ciputri, Kecamatan Pacet, Kabupaten Cianjur).
Abstrak: Penelitian ini bertujuan untuk menganalisis dampak dari perluasan Taman Nasional Gunung Gede Pangrango terhadap perubahan pola penguasaan lahan dan pengaruh perubahan pola penguasaan tersebut terhadap struktur nafkah rumah tangga petani. Penelitian ini menggunakan pendekatan survei dengan data kualitatif dari wawancara mendalam. Hasil penelitian menunjukkan bahwa perluasan taman nasional memiliki dampak negative terhadap (i) status dan pola penguasaan lahan maupun pola penggunaan lahan, (ii) struktur nafkah dan pendapatan rumah tangga. Perubahan penguasaan lahan mengakibatkan sebesar 40 persen responden tidak menguasai lahan di dalam dan di luar kawasan. Dampak lebih lanjut dari perubahan ini adalah berubahnya struktur nafkah yaitu sebesar 82 persen responden hanya bekerja di sektor on-farm. Adapun, persentase pendapatan rumah tangga di sektor on-farm mengalami penurunan yaitu sebesar 92.1 persen menjadi sebesar 73.3 persen dari total pendapatan rumah tangga namun mengalami peningkatan di sektor off-farm dan sektor non-farm.

Judul: Dampak Perluasan Taman Nasional Gunung Gede Pangrango terhadap Strategi Nafkah Rumahtangga Petani Desa Ciputri
Abstrak: The purpose of this research is to analyze land tenure situations at Ciputri Village before and after the expansion of Gunung Gede and Pangrango National Park; and to analyse the impact of national park expansionto the farmer’s livelihood strategy. The research applied a quantitative approach supported by qualitative data. Quantitative data obtained through structured questionnaires to 30 household’s repondents. The qualitative approach applied observation instrument, in-depth interviews, and secondary document collections. The results are, first, the expansion of TNGGP significantly change the tenurial structure of Ciputri’s farmers. Before the expansion, all farmers’ respondents operate land at a minimum of 2,000 m2 of land. However, after the expansion, most of the farmers or 21 out of 30 respondent fall into landless farmers (or tuna kisma). Second, the land tenure changes,furthermore, affect significantly the livelihood strategy of the farmers’ respondent. Before the expansion of TNGGP, the livelihood of all respondent are only on agriculture as farmer operator. However, after the expansion, the livelihood of the farmers changes dramatically. As much as 22 out of 30 respondent engage in two jobs for their livelihood such as work as daily farm labor and various daily service work. The others, 6 respondent, engage in three to four jobs for their livelihood such as work as daily farm labor, smallholder farmers, and various type of daily service work in the village.

Judul: Membran Komposit Kitosan-Zeolit untuk Aplikasi Direct Methanol Fuel Cell
Abstrak: Direct methanol fuel cell (DMFC) is a fuel cell that utilize methanol as the fuel source. The electrolyte membrane used in the DMFC system in this research was chitosan-zeolite composite membrane. The composite membrane was synthesized with chitosan-zeolite composition variation of 1:1, 1:2, 1:3, and 2:1. The membranes were analyzed by Fourier transform infrared spectrophotometer (FTIR) and scanning electron microscope, and for the specific gravity. Membrane performances were tested with methanol uptake, methanol permeability, conductivity, and potential difference in the DMFC system. The FTIR spectrum showed no formation of new functional groups inducating that the composite membrane was a result of physical mixing. Morphological analysis showed that the membrane was nonporous. Chitosan-zeolite 1:3 composite membrane had the highest specific gravity and methanol uptake, 1.4226 g/mL and 41.44%, respectively. The highest proton conductivity was showed by the 1:2 chitosanzeolite composite membrane, namely 7.2946× 10-7 S/cm. Based on this research results, chitosan-zeolite composite membrane can be applied in DMFC system.
