Abstract

Fishing port scan support fishery resources management by incorporating social-economic activities to improve the local community's welfare; however, it can also negatively impact the environment by increasing waste pollution to the surrounding waters. Kutaraja Fishing Port, Banda Aceh, is one of the active fishing ports that conduct multiple activities, such as industrials, transportations, and domestic activities threatening the environment through the production of pollution such as heavy metals. The purpose of this study is to determine the concentration of heavy metals Zinc (Zn) and Chromium (Cr) and the sediment contamination level in the Kutaraja Fishing Port, Banda Aceh. This research was conducted in February 2021 at the water site of Samudra Kutaraja Fishing Port, Banda Aceh, and sampled sediments using the purposive sampling method. Samples were then analyzed for heavy metal concentration using the Atomic Absorption Spectrophotometer (AAS) instrument in the laboratory of the Aceh Industrial Research and Standardization Center (BARISTAND). The results showed that the concentration of heavy metal Zn ranged from 15.6507 - 27.2939 mg/kg. The majority of heavy metal Cr concentrations were below the test limit of 0.000, except at station 2, which was 9.1212. Both heavy metal concentrations are still categorized as low contamination criteria and still below the Australian and New Zealand Environment and Conservation Council (ANZECC, 2000) and the Canadian Council of Ministers for the Environment (CCME, 2002). This research proved that both heavy metals do not threaten the biota and have a low contamination level in the waters.Keywords:SedimentHeavy metal (Zn)Heavy metal (Cr)Atomic-absorptionSpectro-photometerAssessment

Abstract

One of the future technologies for a safe hydrogen storage media is  metal hydrides. Currently, Mg-based metal hydride has a safety factor and efficient for vehicle applications. However, the thermodynamic properties of magnesium hydride (MgH2) found a relatively high temperature. High desorption temperatures caused MgH2 high thermodynamic stability resulting desorption enthalpy is also high. In this study, natural mineral (iron ore) has been extracted from iron sand into powder of magnetite (Fe3O4) and used as a catalyst in an effort to improve the desorption properties of MgH2. Magnetie has been successfully extracted from iron sand using precipitation method with a purity of 85 % , where the purity of the iron sand before extracted was 81%. Then, MgH2-Fe3O4 was milling using mechanical alloying method with a variety of catalysts and milling time. The observation by XRD showed the material was reduced to nanocrystalline scale. MgH2 phase appears as the main phase. DSC test results showed with the addition of Fe3O4, the desorption temperature can be reduced up to 366oC, compared to pure pure MgH2 reached by 409o C. Furthermore, based on gravimetric test, the hydrogen release occurs at a temperature of 388o C, weight loss  of 0.66 mg during 16 minutes.

Abstract

Aceh Besar Regency, in this case Mesjid Raya District, is an area that has quite promising geological conditions, both in terms of the type and distribution of rocks. This makes it possible for many mining excavations that have high economic value to be found in this area. However, the utilization of these mining materials has not been optimized until now. One type of mining material in question is pumice. This pumice is found in large quantities in Paya Kameng village. However, so far the people in this village have only used it as additional building materials without any effort to increase its benefits. Therefore, it was tried to use it for raw materials in the industrial and construction sectors such as in the manufacture of concrete bricks. Concrete bricks (paving blocks) are a type of non-structural concrete that can be used for roads, parking lots, sidewalks, parks and other needs. Concrete bricks are made from a mixture of type I portland cement and water and aggregates as fillers. Aggregates or fillers occupy 75% of the total volume of concrete, so that the properties of the aggregates have a major influence on the behavior of hardened concrete. The aggregate that is often used is sand.

Abstract

ABSTRACT The use of hydroxyapatite (HAp) based on Aceh's bovine bone has been studied as a candidate for thecoating dental implant materials. In this study, the effect of sintering temperature and viscosity on the thickness ofthe hydroxyapatite layer on the 316L stainless steel plaque was observed. The hydroxyapatite was synthesized frombovine bone and then coated on the plate using the dip-coating method. Then, the plate surface was dried at 110 Cfor 30 minutes and sintered with various temperatures of 500, 600, 700, and 800 C for 1 hour. The plate that hasbeen coated with hydroxyapatite was characterized using a thickness meter to measure the thicknesses of the layer.The water composition of 10 grams/L had a better effect on the thickness of the implant material coated with HApbeef bone compared to the water composition of 4, 6, and 8 (gram/L) (p0.05). On the other hand, the temperaturefactor did not affect changes in the thickness of the implant material (p0.05). The higher water composition (10grams/L) resulted in a decrease in the thickness of the implant material coated with beef bone HAp.
