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).

Judul: Effectiveness of thiamethoxam for control of  the  housefly  (musca  domestica)  using  spray method  in  caged-layer  poultry  house
Abstrak: Lalat rumah atau Musca domestica adalah sebagian dari serangga yang paling dikenal dan diketahui tersebar luas di berbagai tempat. Lalat ini umumnya ditemukan pada peternakan ayam petelur. Keberadaan lalat pada peternakan ayam petelur dapat menimbulkan gangguan sanitasi kandang, menularkan penyakit, menurunkan produksi telur, dan mengganggu pekerja. Tiametoksam merupakan insektisida dari golongan neonikotinoid yang diketahui dapat dipakai dalam pengendalian lalat, namun belum banyak digunakan di Indonesia. Penelitian ini bertujuan untuk mengetahui efektivitas tiametoksam sebagai insektisida residual terhadap Musca domestica dengan metode spray di peternakan ayam petelur. Penelitian dilakukan di peternakan ayampetelur KM 45, Kemang, Bogor, dengan membandingkan populasi lalat yang diberi perlakuan tiametoksam terhadap kontrol. Pengukuran populasi dilakukan dengan menggunakan kertas berperekat. Hasil penelitian menunjukkan bahwa tidak ada perbedaan nyata antara populasi lalat yang diberi perlakuan tiametoksam dibandingkan terhadap kontrol, baik dilihat dari jumlah lalat maupun efek residual, The house fly, Musca domesticais one of the best known and most widely distributed insects in human settlements. They are commonly found in poultry farm. The presence of these flies, particularly in large number on layer poultry farm can lead to nuisance of cage sanitation, transmission of disease, reduction in egg production, and workers interference. Thiamethoxam is a neonicotinoid insecticide that effective in the control of flies, but has not been widely used in Indonesia. The aim of this study was to determine the effectiveness of thiamethoxam as residual insecticide against Musca domestica with the spray method in poultry farm. The study was conducted at the KM 45 poultry farm, Kemang, Bogor, by comparing the population of flies in cages which treatedwith Thiamethoxam insecticide toanother cage as controls. Population measurements performed using sticky fly paper. The results showed that there was no significant difference between fly population on control compared to sprayon treatment, in terms of the number of flies and also residual effects

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
