Abstrak: The objective of this research was to measure the coconut shell liquid smoke effect for house fly (Musca domestica). Grade 2 of liquid smoke, resulted from pirolisis process of coconut shell was mixed with alcohol 50% until the concentrat of liquid smoke solution reached 100%, 75%, 50%, 25%, and 0% (50% alcohol without liquid smoke used as a control). Evaporizer used to turn the liquid into vapor. Each treatment was used 50 house flies, age 7-10 days. The treatment was repeated three times. The result of data analyzed with ANOVA and Duncan method. This research conclude the liquid smoke solution at 50% concentration had a highly knockdown effect and 100% concentration had a highly repellent effect for house fly (Musca domestica).

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.

Judul: Solusi Geometri Schwarzschild untuk Dimensi 4+1 dengan Invarian Rotasi Isotropik.
Abstrak: Metrik Schwarzschild merupakan solusi eksak pertama dari persamaan medan Einstein dengan mangasumsikan metrik statik dan simetris. Metrik Schwarzschild yang ditemukan oleh Karl Schwarzschild masih dalam dimensi 3+1, namun seiring dengan teori-teori terbaru yang menunjukkan bahwa alam semesta tidak hanya di dimensi 3+1. Maka melalui penambahan dimensi, tujuan penelitian ini memperoleh solusi pada geometri Schwarzschild untuk dimensi 4+1 dengan memodifikasi koordinat bola yang invarian rotasi isotropik dan melalui penurunan rumus seperti koordinat bola, simbol Christoffel, dan tensor Ricci. Selain mendapatkan solusi ini, metrik Schwarzschild dimensi 4+1 dapat digunakan sebagai metrik dasar untuk memperoleh solusi blackhole dan wormhole pada dimensi 4+1. Hasil akhirnya, dengan memanfaatkan modifikasi koordinat bola, metrik Schwarzschild dapat dibentuk sehingga diperoleh solusi geometri Schwarzschild untuk dimensi 4+1.
