Perancangan modifikasi gedung direktorat jendral pajak Jawa Timur dengan system rangka pemikul momen khusus
No full textGedung direktorat jenderal pajak ini dimodifikasi dan dirancang dengan menggunakan metoda Sistem Rangka Pemikul Momen Khusus (SRPMK). Komponen struktur dari gedung ini adalah dirancang agar mampu menahan momen, gaya geser dan gaya aksial. Modifikasi yang dilakukan terhadap gedung ini cmtara lain yaitu tinggi bangunan, perubahan atap baja menjadi plat beton pada lantai ke 7 dan ketinggian gedung. Tinggi gedungyang semula 42,5 m menjadi 29 m.SNI 03 - 2847 - 2002 dan SNI 03 - 1726 – 2002 digunakan sebagai acuan untuk melakukan perancangan ini, selain peraturan lain yang berlaku.Penults berharap tugas akhir ini dapat digunakan sebagai standart prosedur perancangan dan sebagai contoh dari perencanaan gedung yang menggunakan Sistem Rangka Pemikul Momen Khusus.

The original Direktorat Jenderal Pajak Building ismodified and designed by using Special Moment Resisting Frame System. The structural components of building are designed to resist the internal forces in terms of bending moments, shear and axial forces. The modifications of the building include the height of the structure, the use of concrete slab instead of the steel roof above the seven story and the height of the building. While the height is expanded from 42,5 mto 29 m. The codes of practice used for the design of the building are mainly SNI 03 - 2847 - 2002 and SNI 03 - 1726 - 2002,
besides other related codes. The author hopes that this final assignment will provide a standard design procedure and example of a building design with Special Moment Resisting Frame System

No full textThe mango red spider mite, Oligonychus mangiferus, is a dangerous pest of mango that causes an indirect reduction in the production and quality of mango fruits. Since there is an urgent need to control O. mangiferus, searching for native phytoseiids that can prey on O. mangiferus may provide promising results in the biological control of this mite pest. In this study, biological and life table parameters of the predatory mites Cydnoseius negevi, Neoseiulus barkeri, Paraseiulus talbii, and Typhlodromus athiasae were determined when fed on O. mangiferus under laboratory conditions. Cydnoseius negevi, N. barkeri, and T. athiasae were successfully fed and developed on O. mangiferus, while P. talbii failed to develop on O. mangiferus. The pre-adult duration did not differ significantly among the three phytoseiids. The longest female longevity was 40.28 days for N. barkeri, while the shortest was 26.04 days for C. negevi. The lowest daily fecundity was observed in N. barkeri females, whereas the highest was oviposited by C. negevi and T. athiasae. Statistically, Typhlodromus athiasae had the maximum intrinsic rate of increase (r) and finite rate of increase (λ), followed by N. barkeri and C. negevi. The shortest mean generation time (T) and the lowest net reproductive rate (R0) were reported for C. negevi. In conclusion, C. negevi, N. barkeri, and T. athiasae successfully fed, developed and sustained oviposition on O. mangiferus. Therefore, they could be considered as important biological control agents of O. mangiferus
Acaricidal Potentials of some Essential, Mineral and Plant Oils against the Predacious Mite Neoseiulus cucumeris (Oudemans) (Acari: Phytoseiidae)
No full textThe direct toxicity of some essential,
mineral and plant oils to the eggs and females of the predacious mite
Neoseiulus cucumeris (Oudemans) was tested in the laboratory. Sweet basil oil
was the most toxic essential oil to females N. cucumeris, while sweet marjoram
oil was the least toxic one (LC50=2.315 and 7.021%, respectively). In contrast,
rosemary oil was toxic to eggs of N. cucumeris, while sweet basil oil was the
least effective oil against predator eggs (LC50 = 2.695 and 11.950%,
respectively). The mineral oil capl-l 1was the most toxic one to adult females
(LC50= 0.849%) while natur'l oil was the least (LC50= 4.691%),
respectively. In contrast, natur'l
oil was proved to be highly toxic to predator eggs while bio-dux oil was the
least effective oil against the egg stage. Females of N. cucumeris suffered a
depression in reproduction when females treated and fed on prey formerly kept
on treated plant leaves with LC50 concentration of each oil used in our studies.
Rosemary and sweet marjoram as well as bio-dux oils seem to be slightly harmful
to N. cucumeris at (LC50) concentration of each oil

No full textLaboratory trials of two neem seed extracts on the predatory mites Amblyseius barkeri (Hughes) and Typhlodromus richteri Karg.
No full textÈ stata studiata l\u27efficacia di due prodotti commerciali contenenti estratti di semi di Neem su due acari predatori, Amblyseius barkeri (Hughes) e Typhlodromus richteri Karg. I due formulati causano una diminuzione dell\u27ovideposizione e una riduzione nel consumo di cibo ma possono essere considerati selettivi nei riguardi di A. barkeri. Margosan-O può essere considerato non nocivo nei riguardi di T. richteri in quanto sono stati osservati su questo predatore solo leggeri effetti negativi. Neem Azal-S risulta nocivo nei riguardi di T. richteri allo 0,2% ma lo è solo in modo leggero alla concentrazione dello 0,05%. Viene riportata inoltre la sex ratio della discendenza in ambedue le specie.The effect of commercial products of two neem seed extracts (Neem Azal-S and Margosan-O) on the predacious mites Amblyseius barkeri (Hughes) and Typhlodromus richteri Karg was studied. In spite of the fact that both Margosan-O and Neem Azal-S decreased eggs laying as well as the food consumption rate, both extracts at the two tested concentrations were considered to be safe for A. barkeri. Margosan-O can be considered harmless for T. richteri as no or only slight adverse effects were observed on the predator. Neem Azal-S seems to be harmful to T. richteri at 0.2% but slightly harmful at 0.05% concentration. The sex ratio of the progeny in both species was recorded
