Abstract

The research about “Identification of Actynomycetes from soil around of Lindu Lake” from September to Desember 2010 the purpose was receiving, to identificate, and screening of Actinomycetes from soil around of Lindu Lake. The metodology is descriptive it means that all character data of isolat fenotive Actynomicetes were reSp.sentatively to be applied for identificating conventionally by applying the key book of identification. The result of this research was obtained six isolats Actynomycetes resepsentatively. They have been chosen to represnt the whole of isolat Actynomycetes nine isolat which were successful isolated from soil around of Lindu Lake. The result of identification obtained three famalies of Actynomycetes consisted of four genus and six Sp.ecies. They were Streptomyces Sp.1, Steptomyces griseus, Streptomyces roseoticillatrus, Herbidospora cretaceae, Micromonospora, and Thermomonospora formonensis. There were many genus of Streptomyces from six isolats. Key words: Actynomycetes, identification, and Lindu Lake.

Abstract

The research to measure of mercury accumulated mercury at spesies Gastropods, (fresh water sanils) in Poboya stream have been conducted from March to May 2012. Snail were collected by “Hands Picking” technique at 4 station with Purpose Random that were based on population density. Snails were became to analysis Lymneae rubiginosa M that founded at station 1,2, and 3., Melanoides torulosa B and Melanoides tuberculatus L that founded at station 4. The result of mesuare of mercury accumulated showed that it’s station and kind snails spesies in station 4 were different. The high consentration found at Melanoides torulosa B in station 4 were 0,09 ppm, and then followed by Melanoides tuberculatus L. in station 4 were 0,06 ppm, Lymneae rubiginosa in station 3 and 1were 0,05 ppm, and the low consentation mercury at Lymneae rubiginosa M. in station 2 were 0,02 ppm. Key words: Gastropods, bioaccumulator, Merkury, Poboya stream

Abstract

Research about decription of fertility of Palu sociaty who did analysis quantitative sperm examination at the Palu Healhty Laboratory was conducted from February – March 2011. The research aimed to know the description of Palu sociaty who did analysis quantitative sperm examination, describe the factor that be related to quality os sperm, and also to find abnormalities in sperm based on the description of fertility from quantitative analysis of sperm that mentioned. From 99 samples that eligible, factors related to sperm quality can be evaluated from macroscopic and microscopic examination. By macroscopic, the average value of cerment volume ranged from 1,6 to 5,0 ml, cement pH ranged from 7,6 to 8,0, cement liquefaction ranged from 36 to 60 minutes, and cement viscosity ranged from 0,6 to 5,0 cm. Microscopicallay, the avarage value the total number of sperm ranged from 61 to 108 million sperm/ ejakulate , sperm concentration ranged from 15,6 to 30 million /ml ejakulate , sperm motility ranged from 2-98%, sperm morphology ranged from 5 to 25%, and leucocyte sperm ranged from 0 to 2 million/ ml ejakulate. These factors are interrelateted to each other. From the description of the factors related to sperm quality was obtained subfertil conditions were 59 patients, there were 10 patients with fertile conditions, and more number of pariens with infertile conditions, there were 30 patients. This is supported by many abnormalities including Teratozoosoermia with total 33 patients, Oligoastenoteratozoospermia equal to 31 patients, Astenoteratozoospermis equal to 16 patients, Oligoteratozoospermia equal to 8 patients , and 1 patient each of Asten ozoospermia and Cryptozoospermia. Key words: Sperm, quantitative analysis of sperm, fertility.

Abstract

The studied of Ability of Formula Beauveria bassiana Balsamo. in tablets forms to Control the Cocoa Pod Borer/CPB (Conopomorpha cramerella Snellen.) have been carried out from April to Juny 2011. The aim of this studies was to determine the ability and where the of formula Beauveria bassiana Balsamo. efficient and effectivines to control it. The studied was designed in Completely Randomized Design (CRD) whit 9 treatments as follows: P01(control without treatment), P02 (control with aquades), P1(5 tablets/liter), P2(10 tablets/liter), P3(15 tablet streatment), P4 (20 tablets/liter) ,P5 (25 tablets/liter), P6(30 tablets/liter), and P7(35 tablets/liter) and for it treatment were made by 3 replications. The Parameter in this study were percentage of dead pupae test, the number of test pupae imago, pupa with in 50% of test dies and test and description of the pupa cocon are infected. The results showed that the formula B. bassiana Balsamo. able to control the CPB, this indicated by percentage pupa mortality increased with increasing concentration of the treatment. The percentage of pupae that become imago decreased with increasing concentrations of P01(93.33%), P02 (80%), P1(56.66%), P2(40%), P3(36, 66%), P4(36, 66%), P5(30%), P6 (13.33%), P7(13.33%). When 50% of test pupae diefaster with increasing concentration of the treatment. While the description of the pupa infected with the texture of stiff, hard, body is white and ratherunpleasantodor. The analysis of the percentage, average of dead pupae showed at the P4 test (53.3%) was the most effective hiss treatment. Key words: Ability, formula, Beauveria bassiana Balsamo, C.cramerella.

Abstract

This study was aimed to know the quality of water refills in the district of east Palu, Central Sulawesi during periode of March until May 2012, with Purposive Random Sampling Method. Ten of fortyeight water refill was chosen as the sampling. This study was quantitatively with MPN (Most Probable Number) method for determination of Coliform used Lactosa Broth (LB) medium. In addition, was also conducted a qualitative test by testing of Escherichia coli used selective medium, there are Eosine Methylene Blue Agar (EMBA) and Mac Conkey Agar and then used Gram staining. The result showed tha the water refills in the district of east Palu were not for the requirements of SNI water with bacteriological test by 1 sampling (values of MPN Coliform about 4,3x101 (43 cell/ml)), and the requirements of SNI water are 9 sampling (values of MPN coliform about 3,0x100 (<3 cell/ml)) from all the sampling. But, for the testing of Escherichia coli is negative. Key words: Coliform, Escherichia coli, Drinking-Water refill station (DAMIU)

Abstract

Research on the "effectiveness of the fungus Metarhizium anisopliae as a biological control agent against the larvae of the fly Musca domestica (L)” was done and focusingin determination of the effectiveness of this fungus as a biological control agent against Musca domestica larvae and to determine LC (Lethal Concentration) 50 and LC 90 on this biological control proceses. This study was designed in a completely randomized design consisting of 6 treatments and 3 replications. Arrangement of treatments i.e. the concentration of M. anisopliae in distilled water was; Po = distilled water without spore suspension, P1 = 5.1 × 1010 spores / mL, P2 = 2.0 × 1010 spores / mL, P3 = 1.0 × 1010 spores / mL, P4 = 5.1 × 109 spores / mL, and P5 = 2.0 × 109 spores / mL. Based on the observations, the mortality percentage rate was reached 93.33% as it in the treatment of spora concentration of 5.1 x1010 spores / mL.Probit analysis showed that LC50 was 8.3 x109 spores / mL with the range between the lower limit and the upper limit were 6.24 x109 spores / mL -11.43 x109 spores / mL. While the LC 90 was 5.0 x1010 spores / mL with the range of the lower limit until the upper limit were 2.8 x1010 spores / mL - 9.9 x1011 spores / mL. Key words: Metarhizium anisopliae, Musca domestica, effectiveness, mortality, biological control
