Judul: Perbandingan Pola Penggunaan Pestisida pada Petani Sayuran dan Petani Tanaman Hias di Kecamatan Cipanas, Kabupaten Cianjur
Abstrak: The most common strategy used by farmers to control pests is the application of pesticide. The use of pesticide by farmers is different for each kind of cultivated crops. The use of pesticide on vegetable crops is more intensive than ornamental plant crops. This study aimed to compare pesticide use patterns between vegetable and ornamental plant farmers, and to know the factors that influence. This study was conducted by using direct survey method using structured questionnaires to collect a primary data. The secondary data was obtained from government institution of Cipanas. The survey location was determined by purposive sampling. The number of respondents were 75 for vegetables farmers and 45 for ornamental plant farmers. The result of this study showed that the most dominant strategy used by vegetable and ornamental plant farmers to control pests and deseases was use of synthetic pesticide. Paterns of pesticide use among vegetables and ornamental plant farmers have some simlilarities and differences. The similarities including knowledge of pesticide use, pesticide selection criteria, dose conformity with recommendation dose, the rotation and mixing pesticides, reading label, and post evaluation of pesticide application. The differences including basic consideration to apply pesticides, active ingredients used, intensity of application, pesticide selection, and pre harvest interval. Several factors may influence the patern of pesticides use on vegetable and ornamental plant farmers were level of education, climate and weather, farmer anxiety when their crops attacked by pest and disease, knowledge of pesticide application, and the presence of pesticides store.

Abstrak: The use of pesticides in vegetables is done intensively. One strategy in order to reduce the use of pesticides is by implementation of the concept of Integrated Pest Management (IPM) which it has been introduced by government through the Integrated Pest Management Field School (IPMFS). This study aimed to identify differences in knowledges, attitudes, and practices IPMFS and non IPMFS farmers in the use of pesticides, as well as the relation to the characteristics of the farmers. The research data obtained directly by interviews using a structured questionnaire in seven villages in District of Batur, with 105 IPMFS farmers and 105 non IPMFS farmers from February to April 2013. The data was then analyzed using the Mann-Whitney test and chi-square. The results show that there is a difference between knowledges, attitudes, and practices at IPMFS and non- IPMFS farmers, and have relationship with each other. Knowledges and attitudes of non IPMFS farmers, as well as the attitudes of IPMFS farmers have a relationship with the farmer education, while practices IPMFS farmers have a relationship with the land ownership status and total income

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
