Detection of Insecticide Resistance in Aedes Aegypti to Organophosphate in Pulogadung, East Jakarta

Dengue Hemorrhagic Fever (DHF) is a major public health problem in Indonesia. Jakarta is a capital city with the highest number of dengue patients. Among sporadic endemic areas in Jakarta, Pulogadung, a district of East Jakarta, is one of endemic areas of this disease. The primary strategy for the control of DHF is based on reducing population densities of the main mosquito vector Aedes aegypti. Organophosphate is an insecticide that has been used for more than 25 years in dengue vector control program. The long term used and sublethal dosage of this insecticide can induce resistance. This laboratory study used microplate test and ELISA reader to determine the increase of alfa- esterase activity in Aedes aegypti larvae for detecting the resistance to organophosphate. Resistance pattern of Ae aegypti to organophosphate insecticide in RW 01 Pulogadung was shown to be: 23% high resistant, 33% medium resistant and 44% sensitive. This result was highly related to local community behavior where we found that the use of insecticide spray by the people was very low (8.8% of the sample). We found that the people who used insecticide spray were only 8.8% of the sample. Therefore, organophosphate still can be used in this area to control the Dengue Hemorrhagic Fever in the future. Based on resistance pattern of Ae aegypti to organophosphate insecticide in RW 01 Pulogadung, we can conclude that organophosphate still can be used in this area to control the Dengue Hemorrhagic Fever in the future

Water Productivity of Newly Developed Lowland Rice Field

. Newly developed wetland rice fields require more water because plough pan layer are not developed. Plough pan is established several years after the field development and its formation depends on the intensity of rice cultivation and the soil properties. Plot scale study was conducted on newly developed wetland rice field originated from upland in Pati village, North Kalimantan Province, Indonesia in 2013. The aim of this experiment was to study the water productivity of the newly developed wet land rice fields. Different water ponding treatments including water ponding layer of 5 cm as control (T0), ponding layer of 3 cm (T1) intermittent with two weeks wetting and one week drying (T2), and saturated condition with water layer of 0.5 cm (T3) were tested. Rice growth, rice grains yield and water productivity were evaluated. Water productivity was computed according to the ratio between rice grains yield and water input. Water input was predicted based on the difference between incoming and outgoing water. In this study water balance was not taken into account in calculating the water input. The results indicated that under saturated condition (T3), plant height and tiller number were significantly lower than the 5 cm ponding and also significantly lower than other treatments. Water productivity between 0.78 and 0.40 gram liter-1 were recorded under ponding water depth of 0.5 cm and intermittent ponding of 5 cm in the wet period

Optimalisasi Waktu Dan Biaya Proyek Dengan Analisa Crash Program

Optimization of time and cost is effort to use short time with minimum cost for reaching a job with good results and profits while still concern with quality of project. Crash Program analysis using addition of working hours, is intended to decrease working hours but it is still keeping the productivity number. The direct cost of the project will increase with the addition of working hours, but inversely proportional to the indirect cost of the project. Therefore, the purpose of this final project is to get optimization point between time and cost of the project, in order to get minimum cost to shorten project implementation time. Crash Program is one of scheduling method to shorten project implemention time. By using this program, earned critical path of a project to decide an acitivity that the implementation time can be shortened

Ag Doped ZnO Thin Films Synthesized by Spray Coating Technique for Methylene Blue Photodegradation under UV Irradiation

Silver (Ag) substituted ZnO thin films were successfully deposited onto glass substrates by spray coating technique. Structure, morphology, and optical properties were evaluated by X-ray diffractometer (XRD), scanning electron microscopy (SEM), and UV-Vis spectrophotometer, respectively. XRD spectra had polycrystalline wurtzite structure; SEM images showed that thin films had different surface morphology at different Ag doping concentration. From transmittance spectra, thin films transparency decreased as well as band gap energy along with increase of Ag doping concentration. Methylene blue (MB) solution was used as a pollutant in the photodegradation studies. Under UV light irradiation, the optimal Ag doping is 25%, with 83% of the decolorizing efficiencies after 3 h irradiation time and apparent constant (kapp) about 9.69 × 10−3 min−1
