Penggunaan Bakteri Bacillus spp untuk Pengendalian Jentik Nyamuk Anopheles spp
Full text linkBased 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
Pengaruh Bahan Pengikat Terhadap Sifat Kimia dan Organoleptik Produk Nugget Tempe
Full text linkThe 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
Meningkatkan Hasil Belajar Siswa Melalui Pembelajaran Kooperatif STAD Berdasarkan Pengelompokan Gaya Belajar pada Siswa Kelas XI SMA Negeri 8 Makassar
Full text linkThis research aim to know increase of achievement student class XIB SMAN 8 Makassar who taught through the cooperative learning The Technique of STAD by grouping of student based on their learning style This classroom action research consists of two cycles; the implementation includes the planning, action, observation and reflection. Cycle I and II were four meetings. This research was conducted in odd semester 2008/2009 with the subject of students as many 35 people. Data of students' learning style were collected from questionnaire results to identify learning style of each student. Student learning outcomes data obtained from tests of learning outcomes at the end of each cycle. Student activity data obtained from two observers using the observation sheet. The results showed that the average student activity has increased the percentage of the cycle I to cycle II. Overall student learning outcomes and according of learning method to increase from cycle I to cycle II. Concluded that the results of studying biology grade students SMA Negeri 8 Makassar XIB was increased after application of cooperative learning The Technique of Student Team Achievement Division by classifying students based on learning style.
Uji Bioaktivitas Antibakteri Ekstrak Kayu Akar Bayur ( Pterospermum subpeltatum C.B.Rob )
Full text linkPterospermum subpeltatum C.B. Rob or bayur is traditionally and widely used as medicine for infection diseases caused by bacteria. Four extract from root stem of this plant were evaluated for their antibacterial activity properties against Escherichia coli, Shigella boydii, staphylococcus aureus dan Streptococcus mutan. All the extract were able to inhibited the bacterial strain except Staphylococcus aureus. Chloroform extract exhibited effect for Shigella boydii and Streptococcus mutan. Hexana extract for Escherichia coli, while methanol extract for Shigella boydii. All extract showed an effect at the same extend (MIC; 50 mg/ml)
