Abstract

The research investigated the influence of four isolates of arbuscular mycorrhizal fungi(AMF) on the growth of duku seedlings. The research used randomized block design with onefactor of some isolates AMF: Glomus-sp 3, 6, 15, and 16 at a dose of 20 g per polybag. The resultsshowed that inoculation of AMF isolates increase the canopy and root growth of the dukuseedlings. Duku seedlings inoculated with mycorrhiza showed higher plant height, stem diameter,dry weight, secondary roots number and length, than the control. Furthermore, mycorrhizalinoculation increased the absorption of nutrients (Phosphor) in the leaves of duku seedlings. Rootstaining results showed that AMF colonization in the duku roots only indicate hyphae; the otherstructures (vesicles, arbuscular and spores) were not detected.

Abstract

Global warming has threatened Indonesian’s agricultural sector and put the sectorvulnerable to climate change. The changes affect the daily air temperature changes, farmerbehavior, and the diversity of insect pollinators. The study aims to determine the daily changes inair temperature, farmer behavior, and diversity of pollinating insects in the village of Serang,Karangreja, Purbalingga, Central Java; and to analyze the relationship between daily airtemperature changes, farmer behavior, and insect pollinators diversity. The research employedsurvey methods. Samples for the daily air temperature measurement were taken purposeviley. Thediversity of insect pollinators on the three farming type and respondens were selected radmonlywith total respondent 99. The results showed that the average daily air temperature in chili farms ishigher than that in tomato and strawberry farm; farmers have a good knowledge about theenvironmental degradation of agriculture land, good attitude and awareness in maintaining andimproving the quality of agriculture, but they have negative behaviour in the use of excessiveinsecticides. Species richness of insect pollinators in tomato farm is higher than that in chili andstrawberry farm. A good knowledge, good attitude, and bad behaviour are closely related to thedaily air temperature and insect pollinators.

Abstract

Hornbill has an important role in forest regeneration, but the limited variety andamount of food available to birds will eventually threaten the population of hornbills.Identification of feed plant and hornbil species diversity was conducted at the HarapanRainforest from March to April 2011. Hornbills plant feed samples were taken right after thebirds were eating. The results showed there are nine plant species of hornbills feed found in theHarapan Rainforest: Santiria apiculata, Elaeocarpus sphaericus, Sapium baccatum, Lithocarpusreinwardtii, Disoxylum excelsum, Ficus curtipes, Knema globularia, Knema furfuracea, andSantiria oblongifolia. Of these nine species, Ficus curtipes is the most preferred feed by thehornbills. Further research also notes that there are seven hornbill species inhabit the HarapanRainforest: crested hornbills (Aceros comatus), rhinoceros hornbills (Buceros rhinoceros), goldhornbill (Aceros undulatus), black kangkareng (Anthracaceros malayanus), black-crestedhornbill (Aceros corrugatus), khilingan hornbills (Anorrhinus galeritus) and ivory hornbill(Rhinoplax vigil)

Abstract

Abstrak Biometric recognition merupakan sistem pengenalan  atau identifikasi seseorang  berdasarkan karakteristik  biologis khusus yang dimiliki oleh orang tersebut, fungsinya  untuk sistem keamanan  dengan  mengenali identitas seseorang. Speech recognition merupakan suatu  proses yang dilakukan  komputer untuk mengenali kata yang diucapkan oleh  seseorang tanpa mempedulikan identitas orang terkait. Pola peningkatan dan penurunan signal suara merupakan ciri khas (feature extraction) dari seseorang dalam hal berbicara , sehingga antara energy rata-rata (Average Energy) bunyi  dan lamanya ambang diam  (Silent Ratio) merupakan faktor yang terpenting untuk mendeteksi karakter dan pola suara seseorang. Sedangkan proses algoritma Fourier Frequency Transform (FFT) digunakan untuk mengcirikan komponen-komponen data pada domain frekuensi. Hasil pengujian yaitu menunjukkan bahwa suara seseorang yang direkam dengan durasi dua detik kemudian dilakukan pembagian sinyal gelombang selama 0,2 detik diperoleh besarnya Average energy adalah 2.323 dan proses Silent ratio sebesar 0.249. Kedua nilai tersebut merupakan feature extraction suara seseorang yang dapat dikenali oleh komputer.   Kata kunci: Avarege Energy, Fourier Frequency Transform, Speech recognition, Silent Ratio
