    This research was conducted on July to October 2010 to evaluate the effect of porang cultivation on the abundance, diversity and composition of soil Arthropods. Change in the abundance, diversity and composition of soil Arthropods was observed using pitfall traps in two study sites (Jember and Madiun). In each study site, samplings were performed in porang cultivation land and non-porang area. A total of 15 traps were put in three lines at each location. The differences in the abundance and diversity were analyzed by using multivariate analyze tests. The soil Arthropod compositions in all locations were compared with Bray-Curtis similarity index. The effect of environmental factors on the arthropod compositions was analyzed using multiple regression. The result showed that the effect of porang-cultivation was not consistent in two study sites. In Madiun, the abundance of
    soil Arthropods in porang cultivation land was slightly higher than that in non-porang, while the diversity was significantly higer in the former location. In contrast the those in Jember was found in vice versa situation. This study indicate that the effect of porang-cultivation was not subtantial to the  composition of soil Arthropods. Therefore practice non harmful porang cultivation should be promoted as a part of agroforestry sistem in both study sites.

    Andrographolide  is  important material  present  in Andrographis paniculata.  This material  can  promote  T  cell  to develop  into  regulatory  T  cell,  CD4+CD25+.  CD4+CD25+ regulatory  T  (Treg)  cells,  a  component  of  the innate  immune   response,  which   play   a  key   role    in  the  maintenance  of  self-tolerance,  have   become  the focus  of  numerous  studies  over  the  last  decade.  These  cells  have  the  potential  to  be  exploited  to treat autoimmune disease. In  this  experiment we  showed  that  the  induction  of  regulatory  cells  in  vivo  has  a  healing effect  on  mice  model  of  rheumatoid  arthritis  (RA).  RA  mice  which  is  intraperitoneally  injected     with
    Andrographis  paniculata  shows  the  effect  of  recovery.  CD4+CD25+ regulatory  T  cells  actively  control  the properties  of  other  immune  cells  by  suppressing    their    functional    activity    to    prevent    autoimmunity.  In this  experiment  we   showed   that  active compound  from Andrographis paniculata  namely  andrographolide  can induce  active  regulatory T  cell  that has an efficacy to cure rheumatoid arthritis in mice model.

    One of  indication of obesity is high LDL-C . Obesity has serious risk to health, it can cause heart disease and stroke. Effort to lower  obesity using drugs have significant side effects such as insomnia, increased blood pressure, dry mouth and so forth. Therefore using natural products that contain glucomannan to reduce obesity and LDL-C is good choise. Glucomannan in the global market derived from Amorphophallus konjac. In this study, we used glucomannan from Amorphophallus endemic East Java to reduce fattened Wistar rats. Amorphophallus that used include  Amorphophallus muelleri,  A.variabilis  (variant: Brongkos 32; Brongkos 5; Wonorejo, Brangsi) and Amorphophallus campanulatus  (Var Selopuro).  Amorphophallus  diet was given to white rats of Wistar strain that
    previously fattened using a mixture of cholesterol and lard, in addition to PARS  (Chicken Feed Race Super) as a basic food. Amorphophallus konjac was used as control. Measurement of LDL-C was conducted in four different time points, namely 1).  Prior to dietary cholesterol, 2). 24 days after the dietary cholesterol, 3) 11 days after Amorphophallus  (+cholesterol) diet, 4). 25 days after Amorphophallus (+cholesterol)  diet. The results showed that the diet of A.variabilis potentially lowered blood cholesterol levels for their respective 22.98%, 5.85% and 7.37% for consecutive variant Brongkos 32; Brongkos 5; Wonorejo. Diet from A.campanulatus and A.konjac had not been
    able to reduce cholesterol to the end of observation (25 days).

    Traditional herbal medicines are now increasingly being appreciated with Western models of integrative health sciences and evidence-based approach both in  the basic  research and  clinic scenario. Ashwagandha is  a commonly used plant in Ayurvedic, Indian traditional medicine. Medicinal value of Ashwagandha (WithaniasomniferaDunal) extends from anti-inflammatory, anti-arthritic, anti-rheumatic, rejuvenation and anti-cancer. Based on the belief that  holistic multi-site mechanism  of action offers greater chance  of  success, the traditional  Ayurvedic medicine  practices the use of  whole herb or its  crude extract. It  opposes  with the mainstream of pharmaceutical  industry  that  uses  single  and purified molecules. In the present study, we  used bioinformatics approach to reveal the mechanism of action of (i) crude extract of Ashwagandha leaf extract and its purified components, (ii) Withanone and  (iii) Withaferin A. Whereas p53-p21 was identified as a common signaling pathway for the three kinds of reagents, specific signaling pathways for Withaferin-A and Withanone were identified. Whereas the crude extract and Withanone were selectively toxic to human cancer cells, WithaferinA showed cytotoxicity to the  normal cells too. The study suggested that the crude extract or a combinational formulamay be a superior and safe natural reagent for cancer treatment.

    Large population, in addition to being capital for country’s development is also contrary be problem and burden for the country. One of effort to control increasing population is contraception. Men should also have same burden in family planning, so it is extremely urgent to develop new, safe, effective, and reversible male contraceptive methods. Among all male contraceptive methods, hormonal approach is the closest to clinical application. One of requirements of an ideal male contraceptive is not affected masculinity and libido, which regulated by testosterone-LH. Inhibin B is hormone which controls FSH secretion, whereas FSH is central hormone of mammalian reproduction,necessary for gonadal development and maturation at puberty and for gamete production during the fertile phase of life. The purposes of this study were to determine role of inhibin B from primary culture of testicular to sperm viability and serum LH levels of rats (Rattus norvegicus) Wistar strain. This study used four groups of treatment, ie K0, K1, K2 and K3 are each injected with inhibin B in PBS with a dose of 0, 25, 50, and 100pgper 200 g body weight (BW) rats. Sperm viability was tested by eosin-nigrosin dye and was examined under light microscopy in 400x magnification, and measurement of serum LH levels through ELISA method. The results showed that administration of inhibin B can reduce viability of spermatozoa significantly, but did not reduce levels of LH in serum. This indicates that inhibin B has potential to be developed as a male hormonal contraceptive.

    Department of Biology, Faculty of Science, University of Brawijaya, Malang


    Porang (Amorphophallus muelleri Blume) belong to the genus of Amorphophallus which is is a large genus of some 170 tropical and subtropical tuberous herbaceous plants from the Arum family  (Araceae). Twenty seven species of Amorphophallus are found in Indonesia. Amorphophallus species are valued for its tuber glucomanan among the species found in Indonesia; A.muelleri Blume is a species with the highest content of glucomannan. Many variants of this species were grown in different places at East Java. Based on morphological characters it is difficult to differentiate between them. To identify whether they were similar variety, a Single Nucleotide Polymorphism (SNP) of non-coding sequence, intergenic region in the chloroplast DNA, trnL-F, was studied using PCR technique. Primers used were trnL-F r 5′-CGA AA T CGG TAG ACG CTA CG-3′ and trnL-F f 5′- ATT TGA ACT GGT GAC ACG AG-3′ The program used was pre heating at 96°C for 2 minutes, followed by 36 cycles of denaturation at 96°C for 30 seconds, primer annealing at 56°Cfor 30 seconds and elongation at 72°Cfor 120 seconds, and the last extention at 72°C for 7 minutes. The PCR resulted in a single band of about 500 bp. Sequencing result show that all the 14 samples from 5 places at East Java had exactly similar sequence that suggested that all sample were similar varieties. Alignment with trnL of Amorphophallus muelleri Blume from NCBI, show that the samples were similar to the species Amorphophallus muelleri Blume.

    The pathogenesis of NIDDM has been studied in various ethnic groups. It appears that insulin resistance can precede the clinical onset of NIDDM. Mutation of the human insulin receptor gene have been identified in patients with severe insulin resistence, and studies of these naturally occuring mutants may provide important insights into the relationship between structure and function of receptor (hINSR) of Indonesian diabetes mellitus patients. The bloods were collected from normal and DM patients from some public clinics and Saiful Anwar Hospital, Malang. DNA and RNA were isolated from blood, and then sequenced by ABIPrims Sequencer. To find out the genomic hINSR, DNA sequences were analyzed and characterized by in silicoanalysis, such as alignment by BioEdit & BLAST program from NCBI, and superimposed by Strap JAVA program, 2D- and 3D-structure analysis Swiss Model program. To examine the cytoplasm pathway tyrosine kinase, using docking hINSR-Tyrosine Kinase domain & IRS-1 (PTB domain) analyzed by Hex 5.1. We found specific of DM protein from 2D-protein profile and some type mutation of hINSR and can change the INSR 3D-protein structure and the 3D ligand structure of hINSR and insulin completely changed on DM patient. According to our result, we suggested that the hINSR protein mutation of DM patient precede abnormally hINSR function against tyrosine kinase and perhaps correlated with genetic syndrome of insulin resistance. The change function is presumed to inhibit the interaction between hINSR and IRS, makes transduction signal disturbance in the process of absorption of glucose leads to insulin resistance of diabetes mellitus.

    Biology Department, Faculty of Sciences, Brawijaya University. Malang Indonesia


    Regulation of immune system is a pivotal to prevent immune attacks against self-components. Mice deficient in the IL-2/IL-15 receptor ft chain, CD122 are model animals of such immune attacks and characteristically have a high number of abnormally activated T cells. Here we show that CD122-deficient mice dominated by the development of abnormal T cells. In this study we found that CD4 and CD8 T cells express high level of CD69 and CD44 molecules. Furthermore, the expression of CD62L molecule becomes low and the number of granulocytes cell increased dramatically. This result indicating that normal cells become dangerously activated T cells in the absence of CD122 endogenous molecule.

    Exogenous IL-2 Promote T Cells Proliferation Under Anti -CD3/CD28 Combination

    Muhaimin Rifa’i

    Biology Department, Faculty of Sciences, Brawijaya University.


    Strategy of both activation and proliferation of the cell interest in vitro plays a very important role for clinical purpose. In this experiment we observed that exogenous IL-2 is required to maintain the survival of activated T cell in vitro. Here we also demonstrated that T cell expansion derived from lymph node activated with anti-CD3/anti-CD28 combination was greatly enhanced in the presence of exogenous IL-2. In the absence of exogenous IL-2 the cell become more susceptible to apoptosis and or necrosis. In the stimulation of anti-CD3/anti-CD28 combination, CD8+ T cells were preferentially stimulated. T-cell activation which plays a central role in the regulation of immune responses, involves multiple intracellular signaling events originating from the cell surface TCR/CD3 complex. Cross-linking of the TCR/CD3 complex by anti-CD3 antibody induces T cell activation, leading to the production of cytokines. We found evidence that stimulated CD8 T cells particularly CD8 CD122 subpopulation express high level of IFNy, while CD4 particularly CD4+CD25-express high level of IL-2. Interestingly CD8+ T cells when stimulated with combination of anti-CD3/anti-CD28 could mimic the cell surfice molecules to double positive CD8+CD4LowT cells.

    The aims of this research were characterizing the allergen proteins and comparing the allergenicity between the raw and steamed-porang tubers by using IgE-Immunoblotting. Three variants of Porang: Klangon-Madiun, Sumber Baru-Jember and Sumber Bendo-Madiun were observed. Protein preparation was done according to Li et al. (2003) method, separated using SDS-PAGE electrophoresis, stained by silver and blotted with semi-dry transfer. Mouse serum with highest titer of IgE from ELISA was used as primary antibody, and Goat anti-Rat IgE Biotin Conjugated was used as secondary antibody. The density of protein bands were analyzed by Chemidoc Gel Imaging and Quantity One 4.6.8 software. The result of IgE-Immunoblotting of those three raw and steamed-porang tuber variants showed that the allergen protein bands profile were similar in each variant, with the appearance of molecular weight 26, 32 and 43 kDa. The density of a 26 kDa allergen was the highest protein in raw-porang. In the other hand, a 32 kDa allergen was the highest protein density in steamed-porang from Sumber Bendo, and a 43 and a 32 kDa allergens were in steamed-porang from Sumber Baru. The density of allergen in steamed-porang from of Klangon was in 26 kDa, but it was lower than that of raw-porang one. These suggest that both raw and steamed-porang had potency to induce allergy.

Antibacterial activity of Lb. plantarum S1.30 against multidrug-resistant Gram negative pathogens (Salmonella spp. and Escherichia coli) and Gram positive pathogens was tested in vitro using well diffusion agar assay. The presence of bacteriocin activity was tested both conventional method and PCR-based method using specific primers targeting a bacteriocin regulation gene, plantaricin A. Furthermore, the antimicrobial production kinetic of Lb. plantarum S1.30 was also conducted against Listeria monocytogenes and Lactobacillus sakei ATCC 15521 in a liquid medium. The antimicrobial substances produced by Lb. plantarum S1.30 inhibited all the indicator bacterial pathogens, with the Gram positive pathogens were more sensitive than Gram negative pathogens. The bacteriocin detection was failure to be demonstrated using a conventional method. While, the PCR amplification resulted a-450 bp-DNA fragment, which indicated that plantaricin A was present in Lb. plantarum S1.30. The results obtained from kinetic studies of antimicrobial production showed that the organic acids produced by Lb. plantarum S1.30 played an essential role in inhibiting the growth of target bacteria. These result suggested that bacteriocin produced by Lb. plantarum S1.30, called plantaricin, could be regulated by a quorum sensing mechanism.

The aim of this study were to compare the abundance, diversity, composition and community structure of soil arthropods between two sites with different levels of tourist activity (high and low) and to analyze the relationship between soil arthropods related to environmental factors. Pittfall traps were used to collect soil arthropods. Soil arthropods which collected from site with high tourist activity was 5062 specimens (11 orders, consisting of 17 families) and from low tourist activity was 1071 specimens (12 orders, consisting of 18 families). The diversity of soil arthropods in site with low level of tourist activity was greater (H ‘= 1,58) compared to site with high level of tourist activity (H’ = 0,80). Composition of arthropods in two sites did not differ (Morisita similarity index was 0,97). Community structure of soil arthropods in two sites was dominated by family Formicidae. Declining of soil temperature, air temperature and light intensity had impact on increasing soil arthropods abundance significantly, but soil pH had no significant effect. Based on F-test result, it was found that the difference level of tourist activity lead to significant changes on the abundance of soil arthropods, but did not cause significant changes on diversity level at the two sites.

    The aims of this research were to study dynamic of local communities activities related to the lake and their contribution to influence eutrophication. Human activities during 1985-2010 were studied by semi-structural interview. The fresh water quality were determined by measuring temperature, brightness, conductivity, pH and dissolved oxygen (DO) in 3.0 m of depth. Qualitative data were analyzed using Microsoft Excel, while the quantitative data were compared to previous data and 2nd class standard of water quality. The results showed that the utilization of Ranu Grati since 1985-2010 has increased from three to eight activities. Local community previously used lake as toillets, sand mining, rice fields, then installed floating net cage of some exotic fish, tourism, garbage discharge, farms and finally they developed floating cages of local glassgobies. Most people >60% reported decreasing fish harvest as declining water quality, but less awareness were observed. Based on the brightness of water reached 99-140 cm and <200 cm, Ranu Grati was classified as eutrophic lake. In addition, the DO rate varied 2.5-3.7 mg.l-1 and some times it was lower than the standard (4 mg.l-1). This decreasing DO was an indicator of lake eutrophication, it was seemly caused by loading anthropogenic organic waste.

    Information about index similarity and habitat characters can used as conservation and domestication program. Hermodice carunculata is one of Polychaeta marine worms that live in littoral zones. The worms live at rocky or dead corals. They eat cone snails Conus sp. or dead fishes, Mollusca and Crustacea. These worms have potency as cancer drugs. The aims of this research are to know genetics population similarity and habitat characters of H. carunculata in Pacitan and Malang Selatan.

    DNA isolation used Doyle and Doyle method (1987). RAPD (Random Amplified Polymorphic DNA) was applied using OPA 2 and OPA 9 as primers to amplified DNA. Amplicons analyzed using Cluster Simple Matching Coefisient analysis on MVSP 3.1 software. Abiotic factors measured directly on the fields, and its analyzed using regression analysis on Minitab 13 software. Substrates type and coordinat points of sample tracked and marked using GPS. The spatial data (characters substrates and H. carunculata distributions) analysis used many software, such as: Mapsource; AutocadMap 2004; arcView 3.3; Mapinfo; ArcGis 9.2 and Corel X3. The result showed that H. carunculata found in coral burrows at littoral zones. Mean of salinity (3,33±0,23) (3,95±0,15) ‰, pH (8,08±0,08)(8,22±0,12) and temperature (29,35±0,25)(30,72±0,72) °C. Index similarity of intra-population calculated about (0,870) higher than index similarity of inter-population (0,793). The highest index similarity of intra-population come from Ngliyep (Malang) population and the smallest from Klesem (Pacitan). While, the highest index similarity of inter-population from Balekambang and Ngliyep, the smallest index similarity of inter-population from Balekambang and Klesem. Dendogram formed three groups because location sampling distances. (Group 1: Balekambang and Ngliyep; Group 2: Godheg Kulon and Klesem; and group 3: outgroup (Perinereis cultrifera)).

    Regulatory T cell ( CD4+CD25+) are one kind of T cell subset that play critical role to control the immune homeostasis. Some substances can promoted the population of CD4+CD25+ cell called immunoregulator. Immunoregulator substances can be natural and artificial substances. Artificial substances usually have side effect and more expensive. So that need some research to screening the natural immunoregulator that can be found from some plants. Some plants have some active compound that potent to regulate the immune condition. Those kind of plants usually used as traditional medicine, i.e. plants from genus polyscias. Polyscias obtuse (BL.) Harms as one of species from genus polyscias may contain of some active compound and also potent to develop as immunoregulator agent. The objective of this research are to investigated the population of regulator T cell in mice after treatment by P. obtuse. This research were conduct by several steps, that are preparing of P. obtuse and acclimatization the mice, gavage the mice using 4 different dose (0 mg/20 g BW; 0,5 mg/20 g BW; 2 mg/20 g BW; and 8 mg /20 g BW) for a week regularly, section and isolation the cell from spleen, doing flow cytometric analysis. Flow cytometric analysis show the percentage of cell from spleen that expressed CD4+CD25+ and the highest population of CD4+CD25+ sel are group that treat by 0,5 mg P. obtuse for 20 g BW of mice, that is 2,31%.

    Nutrigenomik merupakan kajian studi tentang pengaruh nutrisi terhadap ekspresi genetik serta komponen genetik pada individu yang mempengaruhi metabolisme dan respon terhadap makanan. Diabetes melitus (DM) merupakan penyakit degeneratif yang salah satunya dipengaruhi oleh pola makan. DM tidak dapat disembuhkan namun dapat dikendalikan, sehingga penderita tetap dapat melakukan aktivitasnya. Diet serat sangat berperan dalam mengendalikan penyakit DM. Penelitian ini bertujuan untuk menganalisis pengaruh glukomanan dalam porang terhadap level mRNA gen proinsulin tikus diabet, sehingga dapat digunakan sebagai acuan pemanfaatan glukomanan untuk mengatasi penyakit diabet. Penelitian ini menggunakan  tikus putih (Rattus norvegicus strain wistar) jantan dengan berat badan minimal 150 g. Tikus dibagi 4 kelompok yaitu tikus non-diabet, tikus diabet, tikus diabet diberi porang 0.06 g/kg BB dan 0.12 g/kg BB. Masing-masing kelompok terdiri dari 2 ulangan. Isolasi RNA total pankreas pada semua kelompok tikus menggunakan QuickPrepTM Total RNA Extraction Kit (Amersham). Analisis mRNA gen proinsulin dilakukan melalui RNA dot blotting dengan probe cDNA. Probe cDNA dibuat dari RNA tikus non-diabet melalui RT-PCR menggunakan Ready-To-GoTM RT-PCR Beads (Amersham), dengan primer spesifik untuk gen proinsulin. cDNA hasil RT-PCR kemudian dilabel dengan biotin (Roche). Hasil penelitian menunjukkan bahwa pemberian diet serat glukomanan dalam porang dengan dosis 0.06 g/kg BB dan 0.12 g/kg BB berpengaruh terhadap peningkatan level mRNA gen proinsulin tikus diabet. Peningkatan level mRNA ini menstimulus terjadinya penurunan kadar glukosa darah pada tikus.

    Study on the release of phosphate from laboratory aquatic sediment incubation and its effect on algal growth has been conducted. The experiment shows interesting results in the context of climate change issue due to a steadly increase of global mean earth temperature on the internal loading of phosphate from sediment. Green algae Scenedesmus collected from Lake Agathis Universitas Indonesia (Prihantini et al, 2007) has been used to test the effect of phosphate from both synthetic nutrient medium and filtrate solution obtained from sedimen incubation. Firstly, Scenedesmus  is cultured in Bold Basal Medium (BBM) with the variation of high phosphate concentration (P) around the level concentration of phosphate in BBM standard, whereas other elements compositions were maintain to be constant. The second experiment was conducted with lower phosphate concentration, less than 1 ppm to approach the level phosphate concentration in the commonly actual situation in the environment. At the third experiment, different phosphate concentration used as a medium collected from sedimen incubation and synthetic medium containing different concentration of P and N. Experiment to study the release of phosphate from sedimen incubation conducted under oxic and anoxic condition, temperature and incubation time have also succesfully been conducted. The effect of of oxygen level in sedimen suspension on the phosphate release from sedimen is shown that anoxic sedimen suspension facilitates the higher phosphate release than oxic sediment suspension. The effect of temperature is very significant on the amount of phosphate release from sedimen incubation conducted under anoxic ondition. It is found  that nutrient addition in synthetic medium in contrast to control, shows the growth of algae Scenedesmus.  Experiment using filtrat sample containing different phosphate concentration from sedimen incubation produce a positive effect on the increase of algal Scenedesmus growth in line with the period of incubation time.

    Keywords: phosphate sedimen, algae, eutrophication.
