Judul: Analisis Risiko Produksi Usahatani Padi sebagai Dasar Pengembangan Asuransi Pertanian (Kasus: Desa Sukaratu, Kecamatan Gekbrong, Cianjur)
Abstrak: Rice is one of the superior agricultural commodities in Indonesia, because the majority of Indonesia's population consumes rice as the main carbohydrate source. Therefore, rice development strategy is needed in addition to increasing the productivity of rice plants, as well as to protect the welfare of farmers as the farm perpetrators from the threat of crop failure risk. Insurance mechanism is one of risk management mechanisms that can protect the welfare of farmers. Sukaratu Village, Sub-district Gekbrong is one of villages in Cianjur that has rice as its agricultural primary commodity. The purpose of this study is to identify the source, probability and risk impact from rice commodity in the village, as well as to determine the ideal premium to be applied in agricultural insurance mechanism. The main source of risk which found in the Sukaratu village is plant pests such as pests and plant diseases, as well as the weather factors. The analysis result using the z-score indicates the probability of the risk by 3.8%. While the results of the analysis using the VaR method shows the impact risk amounted to Rp7 682 020-. Premium value obtained through the method of class rating is Rp390 222.-.

Judul: Analisis Risiko Produksi Padi di Desa Pasirkaliki, Kecamatan Rawamerta, Kabupaten Karawang, Jawa Barat
Abstrak: Padi merupakan sumber bahan makanan pokok penduduk Indonesia. Usahatani padi biasanya rawan akan risiko dan menjadi ancaman terhadap kesejahteraan petani padi di Indonesia. Strategi pengembangan komoditas padi diperlukan selain untuk menambah produktivitas tanaman padi, juga untuk melindungi kesejahteraan petani dari ancaman risiko gagal panen. Desa Pasirkaliki merupakan salah satu desa yang memiliki komoditi unggulan berupa padi. Penelitian ini menggunakan metode analisis secara kualitatif dengan mengidentifikasi sumber-sumber risiko produksi yang ada. Analisis kuantitatif dilakukan dengan menganalisis probabilitas dan dampak risiko dengan metode z-score dan Value at Risk yang hasilnya digunakan untuk penentuan strategi penanganan risiko. Hasil menunjukkan sumber risiko utama yang ditemukan di Desa Pasirkaliki adalah organisme penganggu tanaman berupa hama. Hasil analisis menggunakan z-score menunjukkan probabilitas risiko sebesar 45.6 persen dan analisa menggunakan metode VaR menunjukkan dampak risiko sebesar Rp 12 026 292.

Judul: Modifikasi zeolit melalui interaksi dengan Fe(OH)3 untuk meningkatkan kapasitas tukar anion
Abstrak: Zeolite structure, that bears negative charge caused by replacement of Si with Al in the process of its formation, makes the zeolite has a function as cation exchanger and some anion exchange. To improve its anion exchange properties, zeolite can be modified by addition of Fe(OH)3. Fe3+ ions will enter empty cavities of the zeolite and bind the anions (ligands) to form complexes. Based on the esperiment, the modified zeolite with Fe(OH)3 can be made from both natural and active zeolites, increasing the anion exchange capacity of the zeolite. The anion exchange capacity of the modified zeolite was higher that of the zeolite before modification,i.e. 5.064 and 17.449 meq/100 g, respectively. Modification of zeolite with Fe(OH)3 inhibited adsorption of methylene blue, due to structural changes in the nature of the zeolite after modification. Zeolite adsorption capacity from methylene blue were the largest on the unmodified active zeolite, which was 0.7199 mg/g.
