Judul: Diversity of flies species in layer poultry farm
Abstrak: Lalat merupakan parasit yang dapat ditemukan dengan mudah di peternakan ayam petelur. Penelitian ini bertujuan untuk menelaah keragaman jenis, kelimpahan nisbi, dan dominasi spesies lalat pada peternakan ayam petelur. Pengambilan sampel dilakukan di peternakan ayam petelur KM 45, Kemang, Bogor, menggunakan tangguk serangga. Seluruh sampel selanjutnya diidentifikasi dan dianalisis untuk mengetahui kepadatan lalat. Kepadatan lalat dinyatakan dengan kelimpahan nisbi dan dominasi spesies. Hasil penelitian menunjukkan terdapat 4 jenis lalat yang ditemukan di peternakan ayam petelur, yaitu Musca domestica, Chrysomya megacephala, Chrysomya saffranea, dan Hermetia illucens. M. domesticamerupakan lalat yang paling dominan. Dominasi spesies lalat pada peternakan ayam petelur secara berurutan adalah lalat M. domestica (42.13%), C. megacephala (33.71%), H. illucens (18.26%), dan C. saffranea (5.90%). Ketiga jenis lalat yang terakhir selalu ditemukan bersamaan dengan lalat M. domestica., Flies are common parasites that easily can be found in layer poultry farm. The aim of this research was to analyze the diversity of species, the relative abundance, and the dominance of flies in layer poultry farm. The samples were collected from Peternakan Ayam Petelur KM 45, Kemang, Bogor, by using the sweeping net. The collected samples were identified and analyzed to determine the density of flies. Fly density expressed with relative abundance and species domination. The result showed there were 4 species of flies found in layer poultry farm. They were Musca domestica, Chrysomya megacephala, Chrysomya saffranea, and Hermetia illucens.M. domestica were the most dominant species. Species domination in sequences were M. domestica(42.13%), C. megacephala (33.71%), H. illucens (18.26%), and C. saffranea (5.90%). The last three species were commonly found along with M. 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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
