Let G be a simple graph of order p and size q. Graph G is called an (a,d)-edge-antimagic totalifthereexistabijectionf :V(G)∪E(G)→{1,2,...,p+q}suchthattheedge-weights,w(uv)= f(u)+f(v)+f(uv); u, v ∈ V (G), uv ∈ E(G), form an arithmetic sequence with first term a and common difference d. Such a graph G is called super if the smallest possible labels appear on the vertices. In this paper we study super (a, d)-edge antimagic total properties of connected of Ferris Wheel F Wm,n by using deductive axiomatic method. The results of this research are a lemma or theorem. The new theorems show that a connected ferris wheel graphs admit a super (a, d)-edge antimagic total labeling for d = 0, 1, 2. It can be concluded that the result of this research has covered all feasible d. Key Words : (a, d)-edge antimagic vertex labeling, super (a, d)-edge antimagic total labeling, Ferris Wheel graph FWm,n.

Antirogo is a sub-district of Jember district, it's surrounding citizen utilize bamboo for daily needs such as building materials, agricultural equipment, bridges, vegetables and crafts. The continuous utilization is not accompanied by efforts of cultivating so that will have impacts on a population decline and preservation of them. Then it needs to do an inventory of bamboo in Antirogo. This research was conducted on March to September in 4 villages (Krajan, Trogowetan, Pelinggian, and Jambuan) used the exploration method.

Molecular dynamics is a popular method to observe the movement of interacting molecules. In this study molecular dynamics method was used to observe the phenomenon of iron corrosion and analyze effect of noble gases as a corrosion inhibitor for iron in liquid metal PbBi. Physical quantities are evaluated from the results of this study including: Mean Square Displacement (MSD), the diffusion coefficient, and for the crystal structure is visualized using Ovito program. The ron is placed in the middle high temperature liquid PbBi, the noble gases is injected into the liquid metal. Based on the three kinds of the noble gases (helium, neon, and argon) thhat injected into the molten metal PbBi, it obtained that Argon is the most effective in inhibiting the corrosion of iron. Argon is able to reduce the corrosion rate of 80.29% iron for temperature of 1023K. One reason to use the noble gas because these gases are difficult to react with other elements.

Conducting polymer is a used material for many purposes, including active compound of chemical sensor. Polypyrrole, one type of conducting polymers, is frequently used because of its advantages, namely owing high conductivity, strong mechanical properties and relatively stable compound. This research was aimed to develop an alcohol sensor based on polypyrrole. Electropolymerisation of the polypyrrole was carried out using cyclic voltammetric technique. This research investigated some parameters electropolymerisation, namely variation of dopant electrolyte concentration, potential scan-rate, surface morphology of the polymer resulted, characteristic of the sensor performance when exposed to some alcohol compounds. According to the result of investigation, it was found that variation of potential scan-rate and dopant concentration has significant effect to the electropolymerisation process as well as to the resulted polymer, as indicated by the voltammogram profiles, the surface morphology of the resulted polymer and the response of resistance change of the polymer when exposed to the alcohol compounds.Keywords: polypyrrole, conducting polymer, alcohol sensor, cyclic voltammetry, electropolymerisation.

The mangrove forest are natural and renewable. resources Mangrove has the physical, chemicaland biological function which highly support the fulfillment of human needs and serve as a bufferbalance of the ecosystem in coastal areas. One of the functions associated with the mangrovebiological existence as a source of diversity of marine life. Marine life is affected by the presenceof mangrove forests among mangrove crab (Scylla serrata) to maintain the ecological balance andcause the energy cycle running fast. This study aims to determine the condition of environmentalfactors, the relative fitness and spatial distribution of mangrove crabin the mangrove forests BlockBedul Kali Segoro Alas Purwo National Park. Data from the study are described and classified bysimilarity of environmental factors, then performed multiple linear regression betweenenvironmental factors with relative fitness and spatial distribution of mangrove crabs. The resultsshowed that the average relative fitness mangrove crabs at all the research station is 69 with astandard deviation of 13.51. Spatial distribution of mangrove crab at any observation station isless than 1, so it can be concluded that the distribution is uniform. Environmental factors withrelative fitness mud crab significant correlation, but no significant correlation betweenenvironmental factors with the spatial distribution of mangrove crabs.

STT (Spin Transfer Torque) can be referred to as a process of manipulation and control of spin current in the field of spintronics. When the material is ferromagnetic nanowire La0.7Sr0.3MnO3injected currents will move the domain wall with accompanying changes of spin currents. In mikromagnetik simulation shows that the application is capable of producing flow velocity or pressure of domain wall in the direction of electron flow. The domain wall pressure generating magnetization changes with increasing current density occurs. To that end, the simulation research was done in order to obtain the effect of the injection of electric current to the magnetization of the material. This phenomenon is simulated by modeling the material into the 3D geometry. The greater the current density is given the domain wall velocity or pressure on the nanowire faster so that the magnetization process is also faster. Changes in the velocity of the fastest domain wall is obtained when the material is injected with a current density as well as M-t get a graph showing oscillation pattern that is denser when the current is increased. Furthermore, the total energy analysis with variations in size diameter of 10 nm, 20 nm and 30 nm. The results show that with increasing diameter, total energy tends to increase.

Insects were collected from rice fields in Karawang West Java. Since insects are dominant in Rice field, their role in the ecosystem are important regarding the rice production. Therefore, the occurance of insect species and their role in ecosystem are important to understand. The aim of this reasearch was to study the insect occurance in rice field in Karawang to obtain the potential candidate for biological control agent. The insects were collected using sweep net, pit fall trap and light trap. Nine insect orders were collected and 49 morphospecies were identified including insect pest, parasitoids, predator, tourist and detritivore. Paederus sp., Cyrtohinus and Micraspis sp., were the most abundant entomophagous insect that is potential candidate for biological control agent in Karawang.

Publisher : Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Jember

Fly ash containing 30-36% silica and 14,52-23,78% alumina can be potentially as raw material for synthetic zeolite such as zeolite A. Zeolite A is an aluminosilicate mineral which is rich in alumina so that this zeolite has a good cation exchange capability. Zeolite A has been synthesized by hydrothermal treatment after NaOH fusion. Fly ash has been fused with NaOH at 550 0C for 40 minutes and hydrothermally treated at 1000C for 5 hours. The hydrothermal treatment was conducted in some various Si/Al molar ratios from 0.90; 1.00.; 1.05; to 1.24. The zeolite A was then analyzed using XRD and XRF. The best zeolite A based on XRD result is zeolite with Si/Al molar ratio of 1.1 with crystallinity of 96,80%. The x-ray fluorescence result showed that the Si/Al molar ratios of the four zeolite samples were close to of Si/Al molar ratios of 1, 1.1, 1.21.3 respectively.Keywords: Fly ash, Zeolite A, Hydrothermal Fusion
