Abstract

Tujuan dari penelitian ini adalah untuk melakukan uji fitokimia dan aktivitas antibakteri dari senyawa metabolit sekunder ekstrak metanol daun Rhizophora mucronata yang diperoleh dari Desa Lappa, Samataring, Kabupaten Sinjai Timur, Sulawesi Selatan. Penelitian ini dilakukan dalam beberapa langkah, diantaranya proses maserasi, penguapan, uji fitokimia dan aktivitas antibakteri. Hasil penelitian uji fitokimia menunjukkan bahwa senyawa metabolit sekunder yang terkandung dalam ekstrak metanol daun Rhizophora mucronata berupa senyawa flavonoid dan alkaloid. Pengujian aktivitas antibakteri menggunakan bakteri Staphylococcus aureus dan Escherichia coli yang dilakukan pada Diameter Daya Hambat (DDH) dengan konsentrasi 10%, 20%, 40%, 60%. Penelitian ini dilakukan di Laboratorium Kimia dan Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Negeri Makassar. Hasil tes menunjukkan bahwa DDH ekstrak metanol daun Rhizophora mucronata paling efektif menghambat pertumbuhan bakteri S. aureus dan E. coli di 40% pada konsentrasi 60% karena memiliki DDH> 8 mm.

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

Abstract.  This study investigated a natural acid-base indicator which is extracted from plants in Kupang city. There are 14 plants that potential as a source of natural indicator for acid base titration, i.e, Kol Ungu (Brassica oleracea Capitata Group), Turi Merah flower (Sesbania grandiflora L. Pers), Belimbing Wuluh flower (Averhoa bilimbi L), Kaktus Merah fruit (Opuntia vulgaris Mill), Ruelia flower (Ruellia simplex), Flamboyan flower (Delonix regia), bugenvil flower (Bougainvillea spectabilis Willd.), Bayam Merah leaves (Amaranthus tricolor L.) Jamblang fruit (Syzygium cumini L.), Murbey fruit (Morus alba L.), Pinang fruit (Areca catechu L.), Sirih fruit (Piper betle L.), Kunyit (Curcuma longa Linn), and Nanas Kerang leaves (Rhoeo discolor). Plants extract shows a sharp color change in acid and base solution. Promising results as a natural indicator also shown in acid base titration which is have similar equivalent point to synthetic indicator. We can use these natural indicators as an alternative to synthetic indicator because they are found to be simple, very useful, cheap, easy to extract, accurate, and eco-friendly.

Abstract

The research aimed to examine the effect of Zn+Fe supplementation on optimalizing the biomotoric ability. One field intervention research among of 40 of a 12-years old group of football players of Makassar Football School (MFS)-2000 in South Sulawesi Province had been conducted to figure out a possible mechanism specifically examined the discrapancies of the change in the increasing rate of biomotoric ability between the targeted and the placebo group. This study was designed with randomized double blind pretest-posttest. A full of 20 participants in group A (targeted group) was supple-mented by Zn+Fe for 6 months while other 20 in group B counterparts were given with placebo. All data related to biometric ability, nutrient supplementation, hemoglobin level as well as IGF-1 level were recorded before and after intervention. The result showed greater increasing in the level of Hb, IGF-1, biomotoric ability: muscle endurance (sit-up test), and aerobic endurance (bleep test) among the targeted group up  to 2.05%, 32,5%, 19.85% and 47.08% respectively, after supplemented by Zn+Fe for 6 months, compared to that number in the placebo group (0.61%; 15%; 5.11% and 11,66% respectively). Moreover, the result demonstrated a positive correlation between the level of Hb and the increasing of ability to perform sit-up (r= 0.361) as well as aerobic capacity (r= 0.325). Similar result found in correlation between IGF-1 and the increasing rate of ability to perform sit-up (r= 0.385) as well as aerobic capacity (r= 0.392). Conclusions, the increasing level of Hb and IGF-1 improved the increasing rate of, muscle endurance in sit-up test as well as aerobic endurance in bleep test. Therefore, giving Zn+Fe supplementation may improvement biomotoric ability in  12-years old group of football players.   Keywords: biomotoric  ability, Zn + Fe supplementation, nutrition feed, fitness tests

Abstract

Penelitian ini adalah penelitian deskriptif yang bertujuan untuk mengetahui kemampuan isolat bakteri penambat nitrogen yang diisolasi dari rhisosfer tanaman padi dan jagung asal Kabupaten Takalar dalam memproduksi zat pengatur tumbuh IAA dan pelarutan posfat. Isolasi bakteri penambat nitrogen dilakukan menggunakan medium selektif bebas nitrogen yaitu Ashby dan Burk’s. Koloni bakteri yang tumbuh dan menunjukkan perbedaan karakteristik dipilih kemudian dikarakterisasi secara fisiologi dan morfologi. Kemampuan menghasilkan IAA dari isolat bakteri dianalisis dengan menggunakan metode spectrophotometry pada panjang gelombang 535 nm. Uji kemampuan pelarutan posfat secara kuantitatif dilakukan pada medium Pikovskaya dengan membandingkan rasio antara diameter koloni dengan diameter zona bening yang terbentuk. Dari hasil isolasi bakteri diperoleh 20 isolat bakteri penambat nitrogen dimana 6 isolat diantaranya terdeteksi mampu memproduksi zat pengatur tumbuh IAA dengan konsentrasi antara 7.35-38.35 ppm. Dari 6 isolat yang mampu memproduksi zat pengatur tumbuh IAA, 2 isolat diantaranya terdeteksi mampu melarutkan posfat dengan rasio zona bening 1,7 cm-2,6 cm sedangkan empat isolat diantaranya tidak memiliki kemampuan dalam melarutkan posfat.

Abstract

This study was an experiment that aims to determine the effect of boiling time on protein content of cowpea tempe. This research was conducted in a laboratory experiment of Biology, Makassar  State University and in Central Laboratory of the Ministry of Health Makassar, Indonesia. The sample used cowpea tempe, made using 100 grams cowpea and 0,2 grams of tempe yeast for each sample, and got treatment without boiling as a control and variety of boiling time treatment for 2 minutes, 4 minutes and 6 minutes. This study used a complete randomized design (CRD) with 4 treatments and 3 replication. Determination of protein content by Kjeldahl method. The results showed that the effect of boiling time was very real (P˂0,05) for protein content, where the highest protein levels found in the treatment of boiling for 2 minutes (8,50). It was comparable with boiling for 4 minutes and 6 minutes, but did not different from the control. The lowest protein content was found in boiling treatment for 6 minutes (4,76). So it can be concluded that the longer time boiling, then lower protein content.
