Abstract

Activated carbon that potentially acts as an adsorbent was prepared from granulated sugar. The activated sugar was prepared through a dehydration process followed by a chemical activation process with a concentrated NaOH solution. To comprehend the properties of prepared ready carbon, characterization of the carbon was needed to be conducted. The conducted methods for prepared activated carbon were FTIR for detecting present functional groups attached to carbon, BET to identify the porous structure of synthesized carbon, SEM method as a morphological indicating method on synthesized carbon, and carbon thermal stability characteristic information from the TGA method. It was found that the prepared activated carbon contained various functional groups. The distinguished functional groups presented were carboxylic acid, free alcohol, NH2, and SO3. The readily activated carbon showed a rough surface to enhance the adsorption process on the synthesized carbon from the SEM characterization method. BET on the readily activated carbon revealed that the activated carbon exhibited type IV isotherm, consisting dominantly of mesopores and micropores as a minority. TGA characterization method showed that the thermal stability of carbon was significantly unstable in the range of 100℃ and around 200℃. It implies that the prepared activated carbon contained OH as one of its functional groups. With all the characterization methods conducted on the readily activated carbon from granulated sugar, it was found that the prepared carbon had the potential to be utilized as an adsorbent. Moreover, it is suggested that the granular sugar-based carbon should be investigated in the following future study in the wastewater treatment process.

Abstract

In this study, Oyster (Crassostrea gigas) shell powder which contains calcium carbonate (CaCO3) was converted into calcium oxide (CaO). The Oyster shell powder that had been activated was utilized for the adsorption of the methylene blue (MB) dyeing material, which is one of waste water concerns. Oyster shells were crushed and sieved into 100 mesh sized powder and then calcinated at a temperature of 600℃ and 800℃ both for 4 hours period. To determine the adsorption equilibrium, methylene blue (MB) solution was used with varying concentration from 10 to 50 mg/L in which the adsorbent weighing 3 g was put into a conical flash and shaken until the adsorption equilibrium was reached. As for the adsorption kinetics, 250 mL MB solution was used with initial concentrations of 10, 20 and 30 mg/L, with an adsorbent weight of 3 g and a solution at pH 11 for each concentration. The evaluation of the experimental data from the adsorption process is well explained by the Freundlich equation, with the correlation coefficient value (R2) found to be 0.9999, where the value of the adsorption intensity (n) is close to unity; this shows that the adsorption is multilayer or in other words the adsorption energy is heterogeneous. The kinetics study also shows that pseudo second-order model is the most applicable to the adsorption process. From the pseudo-second-order model, with the correlation coefficient between 0.9984 - 0.9999 can explain that the methylene blue (MB) adsorption process is chemically based sorption or in other words termed as chemisorption.

Abstract

Corrosion Under Insulation (CUI) can be described as localized corrosion that forms as a result of the penetration of water or moisture through an insulating material. The pipe material used is of the ASTM A53 standard and the fluid used in seawater because almost all industries are located on the coast. This type of coating is carried out on the test pipe using Meiji Epoxy Filler. The test method is carried out by flowing seawater fluid in pipes with water temperature variations of 30°C, 50°C, and 70°C. This pipe varies the type of insulation by using glasswool and Rockwool (ASTM G 189-07). This insulation is conditioned in a wet state by giving 2 ml of seawater drops with a pH value of 4 per 6 hours. The test equipment is divided into 3 series according to temperature variations with 4 test specimens and 2 coating variations respectively. The test time was carried out for 336 hours to obtain the corrosion rate results using the ASTM G31-72 weight loss method. The results showed that the type of Glasswool insulation with specimens coated had the lowest corrosion rate value of 0.00483 mmpy at a temperature of 30°C when compared to the same type of treatment on Rockwool insulation of 0.00724 mmpy or an increase of 2.41 times. This study shows that the type of insulation, temperature variation, and coating greatly affect the rate of corrosion and the type of corrosion that occurs is uniform corrosion.

Abstract

Samudera Pasai is one of the Islamic Sultanates in Indonesia which appeared in the Middle Ages or around 1267 AD. Evidence of the existence of the Sultanate of Samuedra Pasai in Indonesia is listed in the book Rihlah ilal-Masyriq (Wanderings to the East) written by Abu Abdullah Ibnu Batutha (1304 - 1368 AD), a Muslim adventurer who traveled to Samudera Pasai in 1345 AD. The spatial pattern of the Samudera Pasai Sultanate is no longer visible because there are no traces of archaeological remains in the form of any remaining buildings, except for the tombs of Sultanate figures and historical records of foreign adventurers who have explored the Samudera Pasai Sultanate. This record strengthens the evidence of the existence of the Samudera Pasai Sultanate. The methodology used in this case is a phenomenological approach and a historical approach, which are expected to approach optimal results in uncovering spatial patterns in the development of Islam. The spatial arrangement of the sultanate generally used the concept of catur gatra tungga, which was arranged in the form of: alun-alun (the square) as the center of space, markets to the north of the square, palaces to the south of the square, and mosques to the west of the square. The spatial arrangement then formed a spatial pattern that became the center of the Samudera Pasai Sultanate.

Abstract

The challenges for searching and utilizing  of new and sustainable energy sources especially solar cell electricity. The major obstacle of using solar cells for electricity generation has been a much higher price when compared to the price of electricity generated from the traditional sources. The photovoltaic industry needs to put an enormous pressure and optimization at every stage of the photovoltaic manufacturing chain of multicrystalline silicon wafer solar cell processing  in order to reduce cost.  Processing of multicrystalline silicon solar cells  is starting by silicon wafer preparation, etching and texturing,  saw damage etching, surface texturing, phosphor diffusion edge isolation, phosphor diffusion, edge isolation, silicon nitride deposition for antireflection coating, and metallization process that consist of screen printing ag front side, screen printing of al back side, drying and firing and formation al back surface contact.  Mechanical stability of silicon wafer became a serious issue due to reduction of wafer thickness, so probability for wafer to breakage is high; investigate the mechanism of wafer breakage is important to reduce breakage. The present of micro cracks reduces the mechanical strength of wafer significantly and wafer breakage will increase, because crack will start from the existing micro crack and that will propagate easier with presence of the stress. Mechanical stability is increase significantly after the etching process; on the other hand the screen printing process will reduce wafer strength.  Etching of saw damage, that is induced during wafer slicing, and metallization of the surfaces are 2 crucial processing steps in the manufacturing of mc-silicon solar cells
