Abstract

Rice Tungro disease is one of biotic constraint that can reduce yield potential of rice. Tungro disease viruses are transmitted from one plant to another by leafhoppers that feed on tungro-infected plants. The most efficient vector is the green leafhopper, Nephotettix virescens. Green leafhoppers (GLH) generally found in areas with high altitude and low temperature. However, GLH and tungro disease can be found in medium and low altitude areas. The aim of this study was to determine the abundance of green leafhopper, tungro disease incidence, and effectiveness of inoculum source in different altitude at endemic areas. Field observations conducted to observe tungro disease incidence and the density of GLH population. Moreover, greenhouse activities were conducted to examine the effectiveness of inoculum sources, including ratoon, spilled grain, weeds, and plants in the vegetative phase. The results showed there was no significant difference in the GLH population dynamics in upland areas represented by Garut and lowland areas represented by Purwakarta, both showed low population density. Ratoon, spilled grain, and plants in the vegetative phase were the effective inoculum sources to be used as host tungro viruses. Keywords: altitude, green leafhopper, inoculum resources, tungro disease

Abstract

Substrate has an important role for growing and surviving of seagrass as a medium of life and as a supplier of nutrients. Lack of attention towards seagrass is because of less information related to the seagrass ecology itself. The aim of this study is to determine the influence of substrate diameter with it’s density. The study was conducted in April in Bahoi coastal, North Minahasa District, North Sulawesi. This study measured water quality, substrate sampling were taken in the field. The result showed that 6 seagrass species: Enhalus acoroides, Thalassia hemprichii, Halodule uninervis, Cymodecea rotundata, Syringodium isoetifolium, Halpohila ovalis, with good water quality and sand substrate types. This coastal area was dominated by small-sized seagrass. The highest density was found at station B with seagrass type was S. isoetifolium and lowest was at station C with E. acoroides and Sand substrate which had big diameter, type T. hemprichii had high density.

Abstract

Rattan biomass is a fiber waste from processing industry of rattan. Its abundant availability, as well as does not threaten the balance of food and feed, make it a potential source as raw material for composite filler of cellulose nanoparticles. To obtain a high cellulose content, it was inoculated with White rote fungi and Aspergillus niger. The experiments were conducted at inoculation time of 15, 21, and 30 days. The results showed that biomass of rattan extracted with White rote fungi and Aspergillus niger reached maximum cellulose content at the inoculation time of 21 days ie 76.47% cellulose, lignin 2.39%, and 20% moisture content. Cellulose has a monoclinic crystal structure, a =7.87; b=10.31; c=10.13 α= γ = 90, β=120. Nanoparticles were produced by disk mill-hummer mill method with variation milling time of  15, 30, and 45 minutes. Collision, friction, and heat for 30 minutes of milling could produce energy that was transferred to the particles and caused cavitation which resulted particles of 16.22-51.30 nm particle size. Production of test piece and prototype of nanocomposite using TSE and injection molding produced material which has 2 phases of crystal structure, namely monoclinic, and orthorhombic phases. The mechanical properties of impact strength was 67.769 J/m and hardness of 79.97 HRR. Thermal properties and density of bionanokomposit showed comparable values with synthetic composites.

Abstract

Lechitocladium angustiovum is fish helminth parasites in the digestive tract to the Rastrelliger genus. The habitat of helminth parasites divided into microhabitat and makrohabitat. Fish helminth parasites infections showed the interaction of extrinsic factors (hosts habitat) and intrinsic factors (biological host). The study was conducted in February-June 2013 in the waters of the Banten Bay (Banten Province) and Pelabuhan Ratu Bay (West Jawa Province). Microhabitat helminth parasites of L. angustiovum that infect R. brachysoma gastrointestinal tract is the stomach and intestines. The presence of fish helminth parasites in fish is mutually beneficial. Fish helminth parasites get food from the fish but its presence prevents other parasites that infect fish. The presence of these worms in the digestive tract is affected by the presence of copepode and small crustaceans that are influenced by the host biology (growth and gonad development) and environmental waters. The number of L. angustiovum from Banten Bay and Pelabuhan Ratu Bay was not significantly different because of the fish has genetically similar populations. Keywords: Banten Bay, habitat, Lechitocladium angustiovum, Pelabuhan Ratu Bay, Rastrelliger brachysoma, short body mackerel
