Judul: Penggunaan Pestisida oleh Masyarakat Kecamatan Cilincing, Jakarta Utara
Abstrak: Penggunaan pestisida rumah tangga merupakan metode yang paling umum digunakan oleh masyarakat untuk mengendalikan organisme yang mengganggu kenyamanan dan kesehatan penghuni rumah. Namun, penggunaan pestisida yang dilakukan secara terus-menerus berpotensi menyebabkan pencemaran lingkungan dan gangguan kesehatan pada manusia dan hewan lainnya. Penelitian ini bertujuan mendapatkan informasi mengenai gambaran penggunaan pestisida oleh masyarakat Kecamatan Cilincing, Jakarta Utara yang dikaitkan dengan upaya untuk mengurangi gangguan oleh berbagai organisme pengganggu. Penelitian dilaksanakan pada bulan Desember 2021 hingga Februari 2022 melalui metode survei langsung dan pengamatan di lapangan dengan mewawancarai penghuni rumah atau yang mendiami rumah yang disurvei sebagai responden dengan menggunakan kuesioner terstruktur sebagai data primer. Jumlah responden sebanyak 60 orang yang diambil dari dua kelurahan yaitu Kelurahan Rorotan dan Marunda. Lokasi pengambilan sampel ditentukan berdasarkan kriteria rumah tangga yang memilki pertanaman di rumahnya. Data yang didapatkan dianalisis secara deskriptif untuk mendeskripsikan penggunaan pestisida menggunakan Microsoft Excel 2010 yang disajikan dalam bentuk tabel. Berdasarkan hasil wawancara, semua responden menyatakan menggunakan pestisida rumah tangga. Jenis pestisida yang paling banyak digunakan adalah insektisida untuk mengendalikan nyamuk dengan formulasi aerosol (58,3%) yang memiliki kandungan bahan aktif paling dominan digunakan adalah transflutrin dari golongan piretroid (86,7%). Frekuensi penggunaan pestisida mayoritas responden menggunakannya setiap hari (48,3%) pada malam hari (61,7%). Secara umum ketergantungan responden terhadap penggunaan pestisida cukup tinggi dan kesadaran akan dampak serta bahaya dari penggunaan pestisida masih rendah., Use of Pesticides by the Community of Cilincing District, North Jakarta. Supervised by DADANG and LIA NURULALIA. Pesticides are the most common method used by people to control pests and diseases, including household insect pests. However, improper and excessive use of pesticides can cause environmental pollution and human health problems. This study aimed to obtain information on pesticide use by the people in Cilincing District, North Jakarta. The research was conducted from December 2021 to February 2022 through direct survey methods and field observations by interviewing residents or those who live in the houses surveyed as respondents using structured questionnaires as primary data. The number of respondents was 60, selected from two villages, namely Rorotan and Marunda villages. The sampling location was determined based on the criteria of households that have plants in their houses. The data were analyzed descriptively to describe the use of pesticides using Microsoft Excel 2010 and were presented in tabular form. All respondents (100%) use household pesticides used to control mosquitoes. The most widely used type of pesticide is an anti-mosquito insecticide with aerosol formulation (58.3%), which contains the most dominant active ingredient used is transfluthrin from the pyrethroid group (86.7%). The frequency of use of pesticides the majority of respondents use every day (48.3%) at night (61.7%). In general, it can be concluded that the dependence of the respondents on the use of pesticides is relatively high and awareness of the impacts and dangers of using pesticides is still low.

Judul: Studies on the behavior housewives in home pesticide usage In Special Capital Region Jakarta
Abstrak: Urban pests such as cockroaches, mosquitoes, flies, ants, termites and rodents are commonly associated with health issues and some are actual disease vectors that can cause severe health problems in a community. Currently, mosquitoes are the main cause of the deadly human diseases, such as dengue fever, chikungunya, and malaria. To control these pests, people commonly use home pesticides because pesticides are considered practical, effective and efficient. However, pesticide uses can has negatively impact human health as well as the environment.The objectives of this study were to examine the behavior of Jakarta residence toward home pesticides use and to assess its impact on the incidence of poisoning the communities.The study was conducted in Jakarta from March to December 2005, with data updated in 2010 and 2011. The object of the research was the homemaker of the households, since women are primarily the decision makers for pesticide application. The study sites were divided into three categories, based on residential conditions : dirty, medium and clean. Information of 155 respondents in several residences in the areas of Jakarta was taken as samples. Observations on the presence of urban pests in the study were done by method landing baiting collection for mosquito, method of feeding to cockroaches and flies, direct counting for ants, and theswing system for termite. The study revealed that cockroaches, mosquitoes, flies, ants and termites are urban pests that are commonly found in households. Pesticide’s that were mostly used has the active ingredient of cypermethrin, imiprothrin and tansfluthrin. Results of the survey showed that 52.74% of respondents acknowledge that TV advertising is an important source of information in providing knowledge about the types of pesticides and 27.40% of respondents know the types of pesticides from experience of her parent behavior. The impact of pesticide exposure on human health can be seen from the symptoms of poisoning or symptoms similar to intoxication. A total of 46.3% housewives surveyed showed symptoms associated with respiratory problems, 5.9% experienced dizziness, 11.1% felt itchy skin, 7.4% of respondents felt nausea and vomiting and as much as 3.7% experienced fainting. Based on the survey, it is known that the characteristic level of education and income levels affect the attitude of homemakers (cognitive, affective and psychomotor) in pesticides used. The attitudes in home pesticide use did not correlate with behavior on the pesticides. Housewives behavior in pesticides use is more influenced by: (1) the level of pest population settlements, (2) advertising and (3) the ease in obtaining home pesticides.

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.
