Judul: Susceptibility of Three Isolates Housefly Musca domestica ( Diptera: Muscidae ) to Three Insecticide Compounds.
Abstrak: Housefly (Musca domestica) is a mechanical vector insect of several diseases, such as dysentry, cholera, typhoid, diarrhea, eye infection (trachoma and epidemic conjunctivitis), poliomyelitis, skin infection, and other diseases which is related to poor environment sanitation. In dairy cows farming, flies could reduce milk productivity; moreover housefly is also potential to be intermediate host of chicken tapeworm in Bogor area. Nowadays, vector control in public health and dairy farm still by using insecticide. Application of insecticide on the similar continuously with high frequency lead to insecticide resistance. This research was intended to study the susceptibility of the housefly Musca domestica which come from locations where has high, middle, and low applied insecticide to insecticide organophosphores, pyrethroid, and nikotinoid. This research has been conducted during March until June 2013. Three different locations has been chosen as source of M. domestica isolates, based on the intensity of insecticide application. Location which has high insecticide intensity is represented by egg-laying hens farming in Bogor area; moderate insecticide intensity by residential in Dramaga area; while low insecticide intensity by Pasar Bogor area. In this research, Bioassay test is conducted by residual insecticide contact method. Malathion 0.8%, Cypermethrin 0.7%, and Thiamethoxam 10% insecticides are chosen here as the residual insecticides. The result shows that three isolates were still susceptible to malathion, cypermethrin, and thiamethoxam insecticides (RR<10). M. domestica isolate which comes from the farming tends to be more tolerant to malathion and cypermethrin than the other isolates.

Judul: Efektivitas insektisida tiametoksam dengan metode paint on terhadap lalat rumah (Musca domestica) di peternakan ayam petelur
Abstrak: Musca domestica is usually the most abundant fly spesies in caged-layer poultry farm. The presence of M. domestica in poultry may cause interference to workers, reduction of egg quality, and may become a mechanical vector insect of several diseases. Nowadays, vector control in public health and farm still by using insecticide. One of the insecticide used in caged-layer poultry house is thiamethoxam. Thiamethoxam is a new neonicotionid insecticides which has not been widely used in Indonesia. This insecticide has a residual effect. This research was intended to study the effectiveness of thiamethoxam as a residual insecticides against M. domestica using the paint on method in caged-layer poultry house. Thiamethoxam painted on polywood board and suspended on the base of caged. The effect of thiamethoxam measured by the flies caught on sticky fly paper to both control and treatment. There was no difference between fly population on control and paint on treatment. The residual effect to M. domestica occurred until 8 weeks after application.

Abstrak: Algoritme ElGamal adalah salah satu algoritme kunci publik dengan aritmetik modular p yang mempunyai struktur grip siklik Z(p). Tingkat keanaman algoritme ini terletak pada pemecahan masalah logaritme diskret dari Z(p). Akan tetapi, tingkat keamanan tadi tahun ke tahun semakin menurun yang disebabkan kemampuan pemecahan algoritme diskret semakin meningkat. Untuk memenuhi tingkat keamanan yang memadai dibutuhkan p yang cukup besar yang menyebabkan proses enkripsi dan dekripsi menjadi lambat.
