Abstract

The advantage of palladium modified La-doped NaTaO3 (Pd/La-NaTaO3)semiconductor photocatalyst for enhanced hydrogen generation under irradiation at the ultraviolet range has been investigated. The La-NaTaO3 has been synthesized by sol-gel technique. The palladiums are loaded by impregnation of aqueous palladium nitrate solution. The palladium supported of La-NaTaO3 composites are characterized by transmission electron microscopy (TEM), high-resolution HRTEM (HRTEM), and X-ray absorption spectroscopy (XAS). The HRTEM images indicate that Pd nanoparticles (NPs) aredeposited on the surface of La-NaTaO3. Most of the Pd deposits have diameters ranging from 3 to 4 nm. XAS spectra shows that the Pd-La-NaTaO3 absorbance profiles of the pristine and used samples are overlapped with the Pd foil, indicating that oxidation of the fresh and used cocatalyst was identical in nature with that of the palladium foil. Hydrogen production from pure water irradiation with ultra violet (UV) light source is 1.1 mmol g-1h-1 on La-NaTaO3 photocatalysts. The activity of the La-NaTaO3 up to 8.9 mmol g-1h-1 H2 froman aqueous methanol solution are obtained. The hydrogen evolution on the La-NaTaO3 sample can be further increase of 36.49 mmol g-1h-1 or 4.1 times higher by depositing nanosized Pd as a cocatalyst on the surface photocatalyst. The highest hydrogen generation is observed at 0.15 wt% Pd loading. The higher activity of the Pd/tantalates from aqueous methanol solution is attributed to an important suppressing in the electron–hole pairs recombination due to the effect produced by the presence of La in the NaTaO3 structure as well as by the role of methanol acts as hole-trap and Pd like electron-trap.

Abstract

Chitosan is a modification of chitin contained in the shell of green mussel which is cationic and biodegradable in the environment. The green mussel shell waste has some great potential benefits because it contains chitin which can be used as the main ingredient for chitosan production for Cu metal adsorption (II). The adsorption was by varying concentration and contact time. The adsorption analysis on the metal content of Cu was done by using the Atomic Adsorption Spectrophotometer (AAS) of Shidmazu type AA 6300 made in Japan. Parameter obtained in this study are adsorption capacity and absorption efficiency of metal Cu (II). Value of adsorption capacity and adsorption efficiency concentration of 5 mg/L are 4,835 mg/g and 96,72 %. The adsorption follows Freundlich absorption isotherm with R2of 0,906 and Freundlich constant (Kf) of 3,3118 l/g and l/n of 0,361. The adsorption of 5 mg/L concentration follows the pseudo second-order kinetics model with kinetics constant (k2) of 0,687 mg/g/min.

Abstract

The shipyard location and model highly influence shipyard industry development. This study aims to assess the location feasibility and determine the shipyard model suitable for shipyard industry development in Kutaraja Fishing Port. The study was conducted in Kutaraja Fishing Port. AHP method was used to determine the location and model, then analyzed using the Expert Choice v11 software. The data were collected using questionnaire interviews and further allocated the value using paired comparison scale table. The result shows that the shipyard industry is feasible to be developed in an area where land parameters adjacent to the waters have a maximum value of 37.3% compared with the five other parameters. The suitable shipyard model to be developed in Kutaraja Fishing Port is the slipway type with a value of 46.1%.Keywords:LocationModelShipyard

Abstract

In this technological era, minerals, in an educational context, refer to components that contribute to overall educational success. Mineral resources serve as the basis for various industries, such as construction, manufacturing, technology, and energy production. This community service activity aims to strengthen the science of high school students at SMP Negeri 6 Banda Aceh so that it can explain the contribution of mineral resources to a country’s Gross Domestic Product. The service team plays a role in providing knowledge of mineral resources to students so that in the future they can develop a basic understanding of earth science. This science strengthening allows students to learn about the formation, properties, and classification of minerals, which are basic concepts in geosciences. The method used is lecture method, question and answer, discussion, and demonstration. The students showed an enthusiastic response to the material presented and participated in the discussion with pleasure.
