Several methods can be used to control pest infestation, especially by the use of biological agents that do not contaminate environment. Virus as a biological agent has already been used to control army worm on some plants. Some benefits can be obtained when biological agents are used to control insect infestation. The objectives of these studies were to obtain: a method to produce MsNPV formulation from rice army worm; an effective and efficient method to pack and store MsNPV formulation as biological agent of rice army worm and an efficient application method of MsNPV formulation to control rice army worm. These studies were conducted at laboratory and green house in Bogor and rice field in Indramayu and Sukabumi, West Java during the planting season of 2005. The experiment consisted of several parts: production of suspension and MsNPV formulation from the larvae of ricearmy worm, packing and period storing of MsNPV formulation, observe the effect of MsNPV formulation on rice army worm in the rice fileds. Results from these studies show that the number of larvae used will effect production of suspension and formulation of MsNPV. The number of larvae used would increase the production of suspension and the value of formulation will also increase. While method of packing, period of time and location of storing showed that time period of 1; 2; and 3 months at different colour of plastic also location of storing refrigerator vs room temperature did not effect on mortality of larvae rice armyworm

MORPHOLOGICAL SPECIES VARIABILITY IN THE STEM-BORER GENUS Sdrpophaga, (LEPIDOPTERA: PYRALlDAE) ON GRAMINEOUS CROPS

The objective of this study is to observe variations between and within species using morphometry. Collections of Scirpophaga were carried out at rice fields in the Northern Coastal area of Java (Pantura): Kerawang, Cikampek, lndramayu, Cirebon, at sugar-cane plantations in Yogyakarta and Pasuruan and various gramineous crops in areas of South Bandung and Lampung from March 1998 to March 1999. Identification was done using morphology of adult characters. Variation within the population groups are recognized by taking measurement of parts of the head, for example measurement of the length and width of the head. Other characters used ill keying adult Lepidoptera to family are those of willg uenation. Also the morphology of male genitalia were used as main characters to differentiate species Results from this studies shownthat: a) Scirpophaga innotata. Measllrement of parts of the head from sample collected showed very little variation, ihier were mentioned as a group. Variation based on wing size, length and width of forewing can bedivided into two groups sizes; the large group size (950 - 1025 lI11n/100) and the smolt group size (850 - 860min/100). Variation based on the size of male gellitalia were more varied in ranging; between 20 - 26min/100 in length and 23 - 35 min/100 but they can be put into one group. b) Scirpophaga incertulas. Measurelllent of parts of the head show little variation in the scattered diagram distribution, and is considered as the same population group. Variation based on wing size, length and width of forewing collected from various places in Java indicated that populations of this insect does not indicate any differences in term of types of wing uenations and considered as similar populatious. Variation based on the size of male genitalia seemed to the same group in the scattered diagmm. c) Scirpophaga excerptalis Measurement of parts of the head(the length and width of the head) considerd as one population. Variation based on the size of nutle genitalia seemed to the smile group in the scattered diagrmn

ANALISIS VALUE ENGINEERING PADA PROYEK PEMBANGUNAN APARTEMENT DI CIKARANG

Abstrak : Biaya untuk sebuah pembangunan suatu proyek sangatlah penting tetapi kalau dalam penggunaannya tidak ada pengendalian maka keuangan pemilik proyek akan rugi. Pada pembangunan proyek apartemen di Cikarang ini pekerjaan arsitektur (pekerjaan dinding, pekerjaan precast facade, pekerjaan plafond, pekerjaan lantai, pekerjaan pintu jendela, pekerjaan railing, pekerjaan sanitair) memakan biaya yang lebih besar dibanding pekerjaan lainnya. Value engineering merupakan salah satu cara untuk menekan faktor biaya tersebut karena akan mengidentifikasi item pekerjaan apa yang mungkin banyak mengeluarkan biaya dengan cara melalui tahap informasi, tahap kreatif, tahap analisa, dan tahap rekomendasi serta menggunakan metode paired comparason dalam menentukan faktor yang akan digunakan sebagai desain penggantinya. Pengeluaran biaya pekerjaan dinding eksisting sebesar Rp.10.189.035.186, setelah dilakukan proses value engineering dengan alternatif 1 didapatkan biaya sebesar Rp. 8.052.748.444 atau ada penghematan Rp.2.136.286.741 (20.97%). Dan dengan alternatif 2 didapatkan biaya sebesar Rp.8.134.383.474 atau ada penghematan Rp.2.054.651.711 (20.17%). Kata Kunci : value engineering, tahap informasi, tahap kreatif, tahap analisa, tahap rekomendasi Abstract : The cost for development a project is very important but if there is not control for its use than the project owner’s finansial loss.
