Abstract

The purpose of the study was to study response of Ganoderma sp. that were given exudate treatment of plant roots. Ganoderma sp. is a pathogen that causes stem rot at base of oil palm. In addition to oil palm this fungus can attack hard and woody crops such as coconut, rubber, tea, cocoa etc. Isolate used is Ganoderma sp. Bio-10197 code obtained from Phytopathology laboratory SEAMEO BIOTROP Bogor. Mycelium Ganoderma sp. reproduced in malt agar media until mycelium grows over agar surface. Ganoderma mycelium was inoculated on 1x1x5 cm rubber wood pieces for 14 days until the mycelium grew over rubber sticks. The exudate used from ganyong (Canna edulis Kerr), garut (Maranta arundinacea Linn.), Ginger (Zingiber officinale Rosc.), Turmeric (Curcuma domestica Val.), Galangal (Alpinia galanga (L.) Sw.) and lidah mertua (Sansevieria trifasciata). The design used in this study was a complete randomized design (RAL) with 7 treatments consisting of 5 repeatations. The results of this study indicate that the mycelium experienced inhibition of growth, especially in the treatment of root exudate galangal shown by 60,81% percentage and tongue-in-law with a percentage of 59,58% colonization. On observation of growth characteristics of mycelium Ganoderma sp. visible zone delimited in the form of a brown mycelium pile suspected as an indication of mycelium rejection of bioactive compounds contained exudate.

Abstract

Rice-field rat is a main pest of rice. Yield reduction caused by rat is quite high, because rats attack rice plant at all stages. One of the efforts applied to control rats is by using Trap Barrier System combined with cage trap. The objective of this research was to identify species of rat attacking rice plants and investigate the presence of  rat by their footprints. The experiment was conducted in Jalur 6  Village Sumber Mulya, Sub-district  Muara Telang,  District Banyuasin, South  Sumatra. One hectare of farmer’s rice field, divided into 3 sub-plot. Each sub-plot was planted with variety paddy of Inpari 22 (sub-plot A), Inpari 33 (sub-plot B), and Inpari 43 (sub-plot C). The number of cage traps was 6 traps per sub-plot. Observations were made 7 times, with an interval of 10 days. Results showed species of trapped rats in the research area was Rattus argentiventer, in which number of males was higher than females. Morphologically, the size of males were bigger than female. Number of footprints did not reperesentative the number of trapped rats. Inpari 43 variety was more preferred by rats because damage intensity was the highest than other two rice varieties.

Abstract

This study aimed to know the influence of planting the flowering plants in sugarcane plantation on the index value of diversity, domination, and the eveness of phytophage and entomophage insect species in sugarcane plantation. This study was done on two-month and six-month sugarcane of PT.  Perkebunan Nusantara VII Cinta Manis District. The research location is located in Ketiau Village, Lubuk Keliat District, Ogan Ilir Regency, South Sumatra. The study was conducted from July to December 2018. Insects that came to flowering plants were collected by using fitfall traps, nets, and direct capture of insects that came. The results showed that the age of sugarcane affected the diversity of Entomophage and Phytophage insect species that came to the flowering plants. At 2-moth-old sugar cane plantations were found 42 species (388 individuals) and 6-month-old sugarcane plantations were found 41 species (284 individuals). The diversity of Phytophage and Entomophage species that came to flowering plants in  the 2-month-old sugarcane plantations was almost the same as in the 6-month-old sugarcane plantations. Phytopage species diversity index values were 2,826 and 2,548, while Entomophage were 2,564 and 2,867.
