Abstract

            This descriptive study aims to do inventarisation of some variety of plants which could be used as material in the practical work of transportation system in plants. The study was done in four phases; exploration of plants in the natural environment, the test of the plants in Natural Science Laboratory of SMPN 27 Makassar, determination of the plants which could be used as practical material in transportation system based on the laboratory test, and “fit and proper” test of the plants used in the experiment which was done by the students of SMPN 27 Makassar. The study showed that there were 9 species out of 25 variety of plants explored in natural environment that could be used in the plants transportation system experiment in laboratory. Those species are Piperomia pellucida (L.)H.B.K., Amaranthus gracilis Desf., Celosia argantea L., Physalis angulata L., Lycopersicon lycopersicum (L.) Karsten, Coleus sp., Coleus swisssunshine, Helianthus annuus L., dan Cleome gynandra L.

Abstract

This research was a descriptive study, which aims to determine the rate of growth of the fungus Rhizopus sp. the green bean tempe. This research was conducted by growing the fungus on PDA medium using fungus inoculum of 1 gram of green beans with tempeh making dilutions, starting from the dilutions 10-2 , 10-3 and 10-4 are plated on a petri dish of 0.1 mL and incubated for 24 hours. Variation of time of fermentation used without fermentation (0 h), 12 hours, 24 hours, 36 hours, 48 hours, 60 hours and 72 hours for each serial dilution. The number of fungi indirectly calculated using the count method bowls. The results of this study indicate that optimum growth is shown in 36 hours fermentation time with the number of colonies on the 10-2 dilution of 69 colonies (6.9 x 103 colonies / g) and 10-3 dilutions of the 27 colonies. While the 10-4 dilution only at the time of fermentation 36, 48 and 60 hours of growth of 2 colonies and each colony 1. The longer the fermentation time decreased the amount of mushrooms.

Abstract

The diversification limitation of exploiting tempe as an alternative nugget raw materials, substitution of meat and fish, and also to optimalize the very abundance resource, so it is necessary to do the right processing to the alternative food resource, which meant to give an additional point. Produce a liked product, also the adjustment of technology, and the cost that reached by the society. The aim of this reseach is to know the kind of glue material which can produce nugget tempe with the best chemical and organoleptic propertics. This research consit of 4 treatment; A1 (tempe nugget from bread powder), A2 (tempe nugget from tapioca), A3 (tempe nugget from sagu), A4 (tempe nugget maizena powder). Water convcentration analyse using oven method. Product was tested by organoleptic test (taste, smell, and tecsture). The result on water concentration analyse, that the smallest water concentration shown by A2  about 161,55% between from treatment A1 abaout 191,75%, A3 abaout 180,02% and A4 182, 45%. The result on organoleptic the teste of A1 product is the most like (75 %) between A2, A3 and A4 treatment. The smell of A2, A3 and A4 is the must like (67 %). And the best tecsture is all treatment.The result of this research is expected to give benefit in supporting the effort saking the alternative nugget glue material by using tempe which owning a high nutrition value. This research it is expected to find a kind if nugget tempe with the good glue, good taste and high nutrition value   Keywords: Glue material, organoleptic, tempe nugget

Abstract

Based on the high incidence and fatality of malaria, a comprehensive management to control the disease, including Anopheles larval control to remove the transmission path, is urgently required. Chemical insecticides used for this purpose is claimed to be less environmentally safe and potentially increase the mosquito resistance.  Thus, there is a need to use alternative insecticide. Some studies found that Bacillus sphaericus dan Bacillus thuringiensis israeli could effectively kill Anopheles larvae and has a low potency to increase resistency. Besides that, it is environmentally safe and does not affect non-target organisms. Therefore, the use of Bacillus spp as larvicides could be undertaken in malaria control programme especially in endemic areas.

Abstract

One of the secondary metabolite, namely a sterol had been iosolated from the n-hexane extract of Phyllanthus niruri L leaves. This compound was obtained by isolation that consist of extaction, fractionation, purification, and identification. The identification covers the melting point test, thin layer chromatography and Liebermann-Burchard test. The research results show that the compound is white needle crystal with the malting point 120-122⁰C and positive with Lieberman-Burchard reagens that give blue-green coulor. This compound have not yet been established, because it must be evaluated by spectroscopy.methods.   Keywords: isolation, Phyllanthus niruri L., sterol, Liebermann-Burchard reagent, spectroscopy method

Abstract

The aim of this research is to show the potential of tree bark of mangrove (Avicennia sp.) plant as antibacterial to against Aeromonas hydrophyla. This bacterium causes fishery cultivation disease e.g. the MAS (Motile Aeromonads Septicemia). Antibacterial activity test was done using paper diffusion and dilution methods. The research result showed that extract of tree bark of mangrove (Avicennia sp.) plant having potency as antibacterial particularly to the A. hydrophyla.

Abstract

The important reason is that botanical insecticides didn’t cause environmental damage and not harmful to human health. As we know, tobacco leaf extract is one of many plant extract that use as botanical insecticides. It can kill fruit fly (Drossophyla melanogaster) that suck domestic plant. On the other hand tobacco leaves extract use as wound therapy also. Those effects   are caused of the chemical compound such as alkaloid, saponyn, flavonoid and polyfenol.The objective of this study is to know the impact of tobacco leaf extract to development of D. melanogaster. Beside that, we observe the effective volume that causes optimal impact. Therefore we mix four type of tobacco leaf extract on D. melanogaster medium. In this case we apply 10 ml (P1), 20 ml (P2), 30 ml (P3) and 0 (P0). Then we observe the mortality. Further the mortality data is compiling by F analysis and LSD.The result shows that tobacco leaf extract caused negative impact to development of fruit fly on all stage of D. melanogaster (larvae, pupae, adult). The most effective impact seems on P3. Hopefully, the result of this study might useful to farmer that use botanical insecticide especially tobacco leaf user. So, user will have more advantages, because it didn’t harmful to human health and environmental.

Abstract

This study aims to determine the enzyme activity of chitinase B. bassiana strain found in South Sulawesi. Knowing the relationship between the activity of chitinase enzyme isolate-isolate B.bassiana strain in South Sulawesi with mortality grayak caterpillar (Spodoptera litura). This descriptive research by linking the enzyme activity of chitinase from Beauveria bassiana strain local South Sulawesi on mortality grayak caterpillar larvae (Spodoptera litura). Based on the research that has been done shows that the activity of the enzyme from South Sulawesi B.bassiana local strains showed differences in each isolate, isolates the origin Enrekang 7.15 units / ml, isolate origin Bantaeng 7.12 units / ml, 6.32 units of isolate origin Pinrang / mi and isolate the origin of Maros 6.2 units / ml. There is a relationship between enzyme activity with mortality rates of larvae of Spodoptera litura. The highest mortality is caused by the isolate origin Enrekang 86%, followed by the isolate origin Bantaeng 83%, 76% Pinrang origin isolates and isolate the origin of Maros 73%.
