Authors: Dani Intan Cahaya , Budiawan Budiawan 
Published: March 2017

Heavy metals such as nickel and cadmium from the waste of human activities (industry, domestic,) can lead the pollution and sediments deposited on the seabed. Water pH changing, can lead to the release (leaching) metals in the sediment into the water body and then it will be bioaccumulated on biota arround the environment. To see the effect of pH changing on the release (leaching) of these metals, extracting the sediment at pH variations has done (TCLP method). From the results of detection metals cadmium (Cd) and nickel (Ni) release studies, to see the hazards of cadmium and nickel metal, carried out a simulation of bioaccumulation test on biota using bioindikator Cyprinus carpio (OECD Guideline 305). Based on the analysis of data obtained in the nickel content in the sediment extract pH 3, 5 and 7 reached 2.55 to 27.94 µg/g, while for cadmium reaches 4.31 to 4.68 µg/g. Observation of metallic nickel and cadmium bioaccumulation in fish hass done for 28 days by looking at levels of cadmium and nickel on the gills of fish and meat. In the flesh of fish, the highest cadmium concentration of 3.179 µg/g while in the gills is 5.392 µg/g. The highest nickel concentrations in fish flesh is equal to 4.557 µg/g while for gill is equal to 10.417 µg/g. The study results indicate the presence of cadmium and nickel metal accumulation on biota. Keywords: TCLP method, biota, Cyprinus carpio

Abstract Waste management system at Semarang State University (UNNES) landfill implements a system of open dumping located in Banaran, Gunungpati, Semarang City. Data from Conservation Team UNNES on December 28, 2010 about the volume of waste per day from UNNES showed that the majority of waste is organic waste. This study aims to determine of 3D distribution leachate. Resistivity geoelectrical method Schlumberger configuration is used to indicate leachate. Data collection was performed three tracks, which three tracks parallel East-West direction, with a path length of 75 m each. The profile of leachate water in the surrounding area of UNNES landfill can be observed ± 20 m depth from the surface. Data processing was performed using software Res2Dinv, Surfer 10.0, and RockWorks 15. Based on the results, resistivity of leachate is 1,87-9,9 Ωm with the direction of flow to a lower elevation areas. Keywords: geoelectrical, leachate, resistivity, Schlumberger's configuration

Abstract One of algebraic structure that involves a binary operation is a group that is defined an un empty set (classical) with an associative binary operation, it has identity elements and each element has an inverse. In the structure of the group known as the term subgroup, normal subgroup, subgroup and factor group homomorphism and its properties. Classical algebraic structure is developed to algebraic structure fuzzy by the researchers as an example semi group fuzzy and fuzzy group after fuzzy sets is introduced by L. A. Zadeh at 1965. It is inspired of writing about semi group fuzzy and group of fuzzy, a research on the algebraic structure of the ring is held with reviewing ring fuzzy, ideal ring fuzzy, homomorphism ring fuzzy and quotient ring fuzzy with its properties. The results of this study are obtained fuzzy properties of the ring, ring ideal properties fuzzy, properties of fuzzy ring homomorphism and properties of fuzzy quotient ring by utilizing a subset of a subset level and strong level as well as image and pre-image homomorphism fuzzy ring.

Published: March 2017

Abstract The Increasing need of storing large amounts of data presents a new challenge. One way to address this challenge is to use distributed data storage system. One of the strategies implemented in the distributed data storage system is using the technique of regenerating code. The code used in this technique is based on the algebraic structure of fields. Some studies have also been carried out to create code that is based on the other algebraic structure namely module. In this study, we attempted to assess the implementation of the code module at regenerating technique code. The study showed there is a potential properties code based on module that can be used in regenerating code technique. Keywords: Distributed storage, regenerating code technique, module code
