Judul: Pengetahuan, Sikap, dan Tindakan Petani dalam Pengendalian Hama Terpadu Tanaman Padi di Kecamatan Malingping, Kabupaten Lebak, dan Kecamatan Petir, Kabupaten Serang.
Abstrak: As the main food crop, rice plays a pivotal role on supporting physiological needs of Indonesian society as well as has high economic value. In order to increase rice yield, farmers have several obstacles to confront such as decreasing land productivity, climate change and outbreak of pest and disease. The problem of pest and diseases inflict a financial loss of farmers, therefore it needs appropriate strategyto control it in order to minimizing the damage. Integrated pest management (IPM) is a comprehensive approach to control pest and disease that had been stated in government policy and environmental friendly. Unfortunately, although the government had socialized to the farmers, the implantation of IPM is still rare. The objective of this research is to study the level of knowledge, attitude, problems and action of farmers on cultivation management of rice including the strategy in controlling pest and disease. The research was conducted in Subdistrict of Malingping (Lebak Regency) and Petir (Serang Regency), Banten Province from May to June 2012. The data was collected by direct interview to the farmers using questionnaire. The result showed that the knowledge of farmers on rice cultivation management was based on heredity knowledge from their ancestor as well as developed from their own experience. Generally, the farmers in Malingping and Petir do not familiar with IPM, this is based on information from the farmers that they did not receive education about IPM from Indonesian government. In fact, the farmer is aware about the important of using healthy seeds, monitoring pest and disease, utilizing natural enemies and using pesticide wisely, that those are important aspect on IPM. In the management of cultivation, the farmers still depend on synthetic pesticide to control pest and disease due to practically simple to apply. Related to climate problem, the farmers tend to defenseless and do nothing without preventive or adaptive approach such as plant rotation that recommended by government.

Judul: Pengetahuan, Sikap dan Tindakan Petani Padi dalam Penggunaan Pestisida di Kabupaten Indramayu Jawa Barat
Abstrak: Pests and diseases of rice are one of the biotic stresses that are able to reduce rice production. Knowledge of the population dynamics of pests is the first step in makingstrategy of insect pest control that should be effective, efficient, and environmentally friendly. Integrated Pest Management (IPM) is a pest management system based on an understanding of the population dynamics and the environment of a pest species, using a variety of compatible control techniques to keep pest populations below the economic threshold and to prevent the population to achieveeconomic injury level. Theobjective of the study wasto know the knowledge, the attitude, and the actions of the IPM field school (SLPHT) andnon-SLPHT farmers. Results showed that knowledge, attitude and action of rice farmers in the use of pesticides in Indramayu district West Java were similar between SLPHT and Non-SLPHT farmers.Both farmers still intensively use pesticides, even those farmers who have attended SLPHT. Farmer characteristics, such as age, education, side job, income, and farming experience did not correlate with the use of pesticides. The use of pesticides was only influenced by habit, praticality in use, and the effectiveness of it.

Judul: Sifat optik dan sifat listrik diode schottky film Barium Titanat (BaTiO3) berstruktur emas - BaTiO3 (Metal – ferroelektrik)
Abstrak: Diode Schottky (emas - BaTiO3) berhasil dibuat dengan ditumbuhkan di atas permukaan interdigital electrode berbahan emas(Au) menggunakan metode Chemical Solution Deposition (CSD) . Film BaTiO3 dibuat dengan proses annealing pada suhu 400oC dengan variasi holding time annealing 4 jam dan 10 jam. Karakterisasi sifat optik diode Schottky dilakukan menggunakan UV-Vis Spektrofotometer untuk memperoleh nilai energi gap Film BaTiO3. Nilai energi gap BaTiO3 pada dua perlakuan holding time annealing 4 jam dan 10 jam sebesar 3.27 eV dan 3.21 eV dan nilai energi gap tersebut termasuk dalam kategori semikonduktor. Karakterisasi sifat listrik diode Schottky dilakukan menggunakan LCR Meter yang didapatkan nilai konduktivitas listrik pada Holding time annealing 10 jam lebih besar daripada 4 jam. Kemudian, didapatkan nilai impedansi yang menunjukkan bahwa pada holding time annealing 4 jam lebih besar daripada holding time 10 jam. Didapatkan pula nilai konstanta dielektrik yang menunjukkan pada waktu holding time annealing 4 jam lebih besar daripada 10 jam.
