Abstract

Background: Dengue fever, up to now been a problem for public health, as well as causing social impact, in terms of the number of people year after year tend to increase and expand the endemic area. One of the Aedes sp control methods is the use of lethal ovitrapObjective : To analyze the effectiveness (larvae of Aedes sp caught ) the use of lethal ovitrap with various types of attractant to control Aedes sp .Method : this study involves the quasi experiment and post test only control group design. Subject of the study is Aedes sp in nature. Data are analyzed descriptively and analytically by using One Way Anova statistical methods.Result discussion : The number of trapped- larvae of Aedes sp by  lethal ovitrap without attractant between 13-15. the number of trapped larvae Aedes sp by lethal ovitrap with various attractant average ranges between 30-95 in door and the average range 9 – 44 out door. There are significant differences amount Aedes sp larvae were caught between treatment both indoor and outdoor ( p = 0.008 and p = 0.007 )Conclusion : There are significant differences amount Aedes larvae were caught between treatment both indoor and outdoor, and lethal ovitrap with shrimp shells attractant water immersion is the most effective way to control Aedes sp mosquitoesKeywords: Lethal Ovitrap, Aedes sp, attractant

Abstract

AbstrakDesain komplesi harus mempertimbangkan beberapa parameter dari sumur, meliputi tekanan, temperatur, jenis fluida yang diproduksikan dan laju alir produksi sumur tersebut, dimana desain harus tahan terhadap beban yang dapat terjadi selama usia sumur. Jenis fluida yang dihasilkan berperan penting dalam pemilihan material, terutama untuk gas asam yang mengandung konsentrasi H2S dan CO2 yang tinggi. Analisa pemilihan material tubing, jenis packer dan aksesoris pelengkap dianggap perlu untuk memastikan bahwa material dan desain dapat menahan semua beban yang mungkin terjadi selama usia sumur.Setelah desain secara konseptual ditentukan, maka desain detail secara keteknikan dapat dilakukan. Pemilihan material dan desian komplesi sumur didasarkan pada kondisi  sumuran dengan menggunakan beberapa metode, seperti stress analysis, triaxial stress analysis dan tubing movement analysis. Material yang terpilih kemudian diuji dengan kondisi  masa  produksi sumur dan selama tahap instalasi  untuk melihat integritas sistem. Tubing 25CRW-80, Retrievable Packer dengan long locator seal bore complete with Perfluoro Elastomers, Tubing Retrievable SCSSV (Surface Controlled Sub-Surface Safety Valve) dan  25CR aksesoris komplesi dapat menahan semua kemungkinan beban selama siklus dan usia sumur.Kata kunci: gas asam, desain, komplesi, material. AbstractWell completion design is an important aspect in oil or gas well before the production phase. Completion design should consider some crucial parameters of the well including pressure, temperature, type of produced fluid and the flow rate of the well, where the design should last and overcome all of disturbance that migh occurs during well life cycle. The type of produced fluid plays an important roles in material selection, especially  for sour gas that contains high concentration of H2S and CO2.  Analyzing the tubing material selection, type of packer and completion accessories is considered necessary to ensure that the materials and design could withstand all the loads during well life. After conceptual completion design is define, then detailed engineering design is proceed. Material selection and completion design   is based on the condition of the well by using several methods, such as stress analysis, triaxial stress analysis and tubing movement analysis. The selected materials   then tested by the well production condition and during the installation phase to see the integration of the system.  Tubing 25CRW-80, Retrievable Packer with long locator seal bore complete with Perfluoro Elastomers, Tubing Retrievable SCSSV (Surface Controlled Sub-Surface Safety Valve) and 25CR completion accessories could withstand all load possibilities for the well life cycle.Keywords: Sour Gas, Completion,  Design, Material.

Abstract

Mosquitoes are vectors of disease and nuisance animals where Culex Sp mosquitoes are vectors of filariasis or elephantiasis. Vector control that has been carried out by the community generally uses chemical insecticides where if the use of chemical insecticides is carried out in the long term and continuously it can cause side effects on the environment, besides that it also causes resistance to the vector itself. This study aims to determine the effectiveness of the peel extract of plantain (Musa Paradisiaca var. Raja) as a larvicide on the mortality of Culex Sp. larvae. This research is an experimental research with The Static Group Comparassion Design. Total population and samples were 600 Culex Sp instar III larvae. The sampling method used random sampling method on Culex Sp instar III larvae or at the age of 3-4 days. Data analysis using Anova analysis using the STATA application. The results of the Anova test showed that there were differences in the mortality of Culex Sp with various doses of plantain peel extract (Musa Paradisiaca var. Raja), the highest effectiveness was 84% with an average mortality of 21 Culex Sp larvae, the conclusion of the study from probit analysis with an LC50 (Lethal Concentration) value of 2,969% and the most effective dose to kill Culex Sp larvae was at a dose of 8%.

Abstract

Chemicals and other materials in the form of jasad renik and viruses are used to prevent or eradicate pests that can damage plants. They are usually called pesticides. Some plants or agricultural products that stimulate plant growth kill some plants without fertiliser and prevent unwanted growth. Severe poisoning refers to low-level long-term effects or exposure to toxic substances, such as frequent spraying of pesticides during dangerous spraying times. The effects of chronic exposure do not appear immediately after the first exposure; it takes a long time for symptoms to appear. Plaosan is one of the villages and sub-districts in Magetan district where part of the population works as vegetable farmers. The population in Plaosan village is 5,678 people spread over 5 hamlets, namely Gulun, Duwet, Kauman, Sale, and Kandenan. To increase optimal agricultural yields, farmers in agricultural intensification usually use pesticides. Pesticides continue to accumulate in the body and slowly damage the tissues. People who are frequently exposed to this pesticide at low doses may suffer from symptoms of poisoning long after their initial exposure. Chronic symptoms include chronic oral inhalation poisoning and chronic skin contact. This research uses a descriptive type of research. Descriptive research is a study that describes the magnitude of the problem under study. Descriptive research is research with the main objective of making an objective picture or description of a situation. This study aims to determine the risk factors for subjective complaints of pesticide poisoning of vegetable farmers in the work area of the Plaosan Health Centre in terms of individual factors, behaviour, environment, and pesticide use. The results of this study regarding the risk factors of subjective complaints All farmers experienced complaints of severe, moderate, and mild health complaints, including headaches, dizziness, nausea, vomiting, a weak body, nervousness, trembling, blurred vision, sweating a lot, a fast heart rate, and difficulty breathing.
