Abstract

The study about “Screening of Aspergillus antagonistic to Phytopthora palmivora causing black pod disease of cocoa at Sulawesi Tengah” has been carried out during three months. The purpose of this study is how to getting the best of local isolats of Aspergillus sp. antagonistic that can be controlling of Phytopthora palmivora. The method of this study is exploring the local Aspergillus fungi as biological control of the P. palmivora causing black pod disease of cocoa in five Districts central of production kakao, such as Donggala District, Parigi Moutong, Poso, Morowali, and Buol. Parameter observed were antagonist test in vitro and pra in vivo on the cocoa. The result of this study was obtained fourteen isolats of Aspergillus sp namely are (1) Poso District: L-1, L-2, L-3 ; (2) Morowali District, L-4, L-5, L-6; (3) Donggala District, L-7, L-8, L-9; (4) Parimo District , L-10, L-11, L-12; (5) Buol District, L-13, L-14. All isolates of Aspergillus sp. were antagonistic in vitro on P. palmivora, but only six isolates, namely are L-1, L-10, L14, L-4, L-6, dan L-8 were have the best ability to controlling P. Palmivora on the cocoa pod. Key words: Aspergillus sp., antagonism, Phytophthora palmivora and Cocoa pod.

Abstract

The research on the structure and composition of mangrove vegetation in the Lalombi Village South Banawa Donggala District has been conducted from November to December 2012 which aims to determine the structure and composition of mangrove vegetation in the studied area. The research was used exploratory survey method by using line (transect method) and in the transects, plots were made in the size 10 m X 10 m for the observation of trees, 5 m X 5 m for the poles and the 2 m X 2 m for seedlings. The result of the research showed that there were 11 species of mangrove namely : Ceriops tagal, Ceriops decandra, Aegiceras corniculatum, Avicennia marina, Sonneratia alba, Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorhiza, Camptostemon philipinense, Xylocarpus molluccensis and Bruguiera parviflora. It’s belong to 6 family that Rhizophoraceae, Myrsinaceae, Avicenniaceae, Sonneratiaceae, Meliaceae and Bombacaceae. The diversity index of Mangrove species at Lalombi village was low. Species Mangrove of trees in the studied area were dominated by Sonneratia alba (INP 82.41%), meanwhile Aegiceras corniculatum (INP 69.71%) and Ceriops tagal were dominant on the level of sapling and seedling (62.21%). Key words: Structure, composition, mangrove, Lalombi village

Abstract

Research of the "Study Zooplankton Community As Overview Water Quality of Central Sulawesi in Palu Bay" was conducted from March to May 2012. This research was aimed to Determine the structure of zooplankton community in waters bay of Palu. Samples were taken vertically and horizontally by using a plankton net and Lamotte water sampling at four research stations, they are: Station 1 in the area of the river mouth of Palu, station 2 in the area of Tondo village settlements, station 3 in the areas of sand mining and quarrying C Taipa, and station 4 in the area of PLTU. Samples were observed and analyzed in the laboratory of the Department of Environmental Biology Faculty of Mathematics and Natural Sciences. The results showed that in the bay Palu found three phyla, 3 classes, 7 orders of zooplankton are classified into 30 types. The results of the analysis of the diversity index (H ') ranged from 0.69 to 2.61 belong to the diversity of medium and low. Uniformity index (E) ranged from 0.60 to 1.00, belonging to the high uniformity. Total abundance at the surface ranged from 0.12 to 3.60 ind / l. Total abundance at depths ranging from 30-490 ind / l. Key words: Community, zooplankton, water quality, the bay of Palu

Abstract

The study about “Formulation on tablet of Aspergillus sp. bioantagonistic agent to Phytophthora palmivora Butler causing black pod disease of cocoa”, was done in the purpose or determining the best formula in Aspergillus sp. teblet formulation, and to determine it viability during 30 days of stronge. This experiment was conducted based on the Completely Randomized Design (CRD), with 8 tretmens and 3 replication. The treatments tested were P0 (100% of chaff), P1 (95 gr chaff + 5% bond supplement), P2 (90 gr chaff + 10% bond supplement), P3 (85 gr chaff + 15% bond supplement), P4 (80 gr chaff + 20% bond supplement), P5 (75 gr chaff + 25% bond supplement), P6 (70 gr chaff + 30% bond supplement), and P7(65 gr chaff + 35% bond supplement). The result showed that the viability of fungi, after 30 days stronge were 100%. The best formulation was P4 as determined based on brittleness test with score 6,73%, its higher than its other formula. Key words: Formulation, biological control agent, Aspergillus sp., and tablet.

Abstract

Rehabilitate forest and farm critical must special attention and need of the new method that more practical, quick, and cheap. Method of seed ball is its alternative method. with consideration referred, then this research bent on for (1) know seed amount every seed ball that give percentage grows and plants growth sengon the best (2) know size of seed ball diameter the best to percentage grow and plants growth sengon; (3) know appropriate type of farm closing to percentage grow and plants growth sengon; (4) know interaction influence between seed amount every ball, level of seed ball, type of the best farm closing to percentage grow and plants growth sengon at the site. This research is executed start month September 2012 up to final December 2012 in district Tinggimoncong Gowa Regency. this research uses random design complete pattern factorial that consisted of 3 factor that is seed amounts every seed ball as first factor with 4 levels that is 5 seeds, 7 seeds, 9 seeds, and 11 seeds every seed ball, second that is large size factor its diameter of seed ball that consisted of 4 levels that is 2.5 cm, 4 cm, 5.5 cm, and 7 cm, third factor that is farm closing that consisted of 4 levels that is opened (grass), coppice, beams, and cleaned (disc with diameter 20 cm). The three of this treatment factor are combined until got counted 4 x 4 x 4 = 64 treatment units. Every treatment unit consisted of 3 seed balls and repeated 3 times until required 64 x 3 x 3 = 576 seed balls. Variable that perceived is time starts germinate and percentage germinates every week during a month first, plants growth (high and leaf amount) every month after second month for 2 month. Research result indicates that treatment of land cover has an effect on reality to germination percentage, leaf amount, and high plants as for seedball diameter, seed amount and interaction between land cover and seedball diameter have an effect on reality to percentage of germination and leaf amount. Treatment of grass land cover gives influence is done well by germination percentage, leaf amount, and high plants. Seedball diameter 7,0 cm and seed amount 11 seeds give influence is done well by germination percentage. Combination of grass land cover treatment and diameter of seed ball 7,0 cm give best influence. Key words: Formulation, biological control agent, Aspergillus sp., and tablet.
