Abstract

Evaluation of forest conditions using longhorn beetles (Coleoptera: Cerambycidae) fauna have been carried out at 3 parts of Mt. Slamet which are, northern part through Guci, southern part through Kalipagu, Baturraden and easthern part through Bambangan. In northern parts, research activities were conducted at about 1200-2500m above sea level (m.asl.), in southern part, research activities was conducted at about 700-1000m m.asl and in eastern part research activities was conducted at about 1500-2400m asl.Out of the 37 species of longhorn beetles were collected during this research, dominated by Sybra fuscotriangularis (55 specimens). The longhorn beetles collected in southern part, indicated lowest individual number (36 spesimen) but indicating hightest species number. In the contrary, the highest number of spesimens collected but lowest species number (10 species) was collected in the eastern part, while in northern part, it was collected 86 individu (17 species).The species compositions and the number of individuals of longhorn beetles collected from each parts (northern, southern and easthern part) were different with specific groups. Longhorn beetles species collected from secondary forest was similar to the primary forest.Distribution pattern of longhorn beetles in Mt. Slamet indicated that some forest species were found at certain altitude such as Batocera spp and Gnoma thomsoni which only found at 700-1000m asl. The forest area which this altitute (700-1000m asl.) was located at the southern part of Mt Slamet (Kalipagu, Baturraden) where known as the main support of water reservoir for electric power and seven spout water (Pancuran Tujuh). Thus this area has to be conserved from illegal logging and human activities.

Abstract

An investigation about the effect of gamma irradiation on the progeny development of male fruit fly (Drosophila melanogaster Meig) pre-marital has been done.The purpose of this study is to comprehend the changes in progeny as well as the probability of abnormal phenotype to fruit fly progeny as the result of gamma irradiation to male fruit fly pre-marital.The study has been conducted using Completely Randomize Design method with six repetitions. Pre-marital male fruit flies were irradiated at the doses of 10, 15 and 20 Gy with gamma ray from "Co source, having a dose rate of 0.66 Gy/hour. The irradiated fruit flies and non-irradiated ones as control, mated immediately with virgin female, then the first progeny (F,) was observed. The parameters used in this study were the total number of progeny and the number of abnormal phenotype of the progeny. The data were analyzed by using Analysis of varians (ANOVA), proceeded with Duncan test. Regression analyses was also perform to comprehend how far gamma irradiation affected the fruit fly progeny. The result indicated that gamma irradiation significantly affected (a=l%) the total number of progeny The average total number of fruit fly progeny caused by gamma irradiation with the doses of 10, 15 and 20 Gy, tend to decrease i.e. 43, 81 and 85%. It appeared that gamma irradiation caused mutation which figures as wing abnormality. It was also found that an irradiation dose of 10 Gy do not caused abnormality. Abnormal phenotype to the wing organ began to appear at the given dose of 15 Gy.

Abstract

Keanekaiagaman primata Indonesia meiupakan suatu kekayaan yang tidak terdapat di negaia lain. Kawasan Indonesia mempunyai primata mulai dari yang berevolusi iendah yaitu Tarsius bancanus sampai yang berevolusi tihggi seperti orangutan (Portgopygmaeus). Beberapa primata ada yang bersifat endemik, seperti lutung meiah di Kalimantan (Davis1962, Medway 1970, Stott & Selsor 1961).Tempat hidup lutung meiah, yaitu pulau Kalimantan, pada dasa waisa sekaiang ini sedang giat dieksploitasi.Eksploitasi diketahui banyak menimbulkan kerugian terhadap penghuninya, misalnya adanya emigrasi dan kepunahan tidak langsung. Beberapa hewan telah menunjukan kelangkaan di daerah yang diekploitasi hutannya.Lutung merah sebagai hewan arboreal mungkin sekali akan terganggu oleh adanya eksploitasi hutan tersebut.Oleh karena kerusakan hutan mungkin akan berpengaruh terhadap tingkah laku lutung, maka penelitian mendasar terhadap hewan ini perlu dilakukan Untuk memulainya dilakukan penelitian awal dalam taraf pengamatan aktivitas, pergerakan dan beberapa segi tingkah laku lutung. Penelitian ini diharapkan dapat membantu cara pelestarian hewan ini.

Abstract

Helicoverpa armigera is one of the most important agricultural pests because it has a high reproductive rate and resulted in economic losses. One of the H. armigera control techniques that is in accord with IPM principle is the utilizing of entomopathogenic fungus. The aim of this research was to test the pathogenicity of Lecanicillium (Lecanicillium sp. PTN01) against H. armigera. Pathogenicity test was conducted by conidia application of Lecanicillium sp. PTN01 on both the larvae and eggs at density of 105, 106, 107 conidia/ml. The control group was only treated with steril water. Polymerase chain reaction (PCR) was performed for molecular identification Lecanicillium sp. PTN01. The results showed that Lecanicillium sp. PTN01 able to inhibit egg hatching 13.75%, and cause mortality of first instar larval survival 98.75%. The result of virulence test to the highest larval mortality at 107 conidia/ml density was 41,25%, with the values of LT25, 50, 75 were 3.95, 7.12, 12.82 (days) and LC25, 50, 75 were 4.6 x 105, 1.7 x 106, 4.6 x 109 (conidia/ml). The DNA sequence analysis of ITS 1 and ITS 4 primers showed that Lecanicillium sp. PTN01 was similar to fungus species L. kalimantanense strain BTCC F23 with 94% homology.

Abstract

Polynesian arrowroot (Tacca leontopetaloides), taka, is one of the tuberous plants that distributed near the sea shore to 220 m above sea level. Taka produces two kind of tubers, parent tuber and peripheral tuber. Local people in several locations used taka for forages, cakes, cosmetics and woven. This plant is a minor crop comodity in Indonesia, so it is not widely cultivated yet, and no informations about taka propagation method and its cultivation. Taka produces both tuber and seed for regeneration propose. Aim of this study was to investigate vegetative propagation of taka and its growth pattern. Results showed that propagation by parent tuber required 24 weeks after sowing to produce new peripheral tuber. Material propagation from new peripheral tuber will become new plant. This new plant will produce next generation tuber in 5 months later. Propagation by peripheral tuber (from field exploration) required 24 -28 weeks after sowing to produce next generation plant with leaves and flower stalk directly. Stolon and the next generation tuber were also produced. Taka tuber can be harvested when its leaf turned yellowish.
