Abstract

Microbial fuel cell consisting two main components which are anode and cathode materials. In the microbial fuel cell, both anode and cathode compartments are separated with a separator. Anode generates the protons and electrons while cathode converts protons into water with the presence electrons and oxygen. During the Microbial fuel cell operation, the performance of anode is very crucial due to it provides the protons and electrons. Hence, the high efficiency microbial fuel cell is very related with the high anode performance. This work addressed to the enrichment process of electroactive bacteria (EAB) in anode of microbial fuel cell. In this work, some parameters such as current generations, , and pH changes were used to assess the enrichment process of EAB was reached. In addition, the presence of EAB on the anode surface was identified based on the morphology of anode surface. The removal of COD and the pH value were determined by using the American public health analysis method and pH tester, respectively. The morphology of anode surface was analysed by using a scanning electron microscope. Whereas, current generation was tested by using a mustimeter. The removal of COD and final pH were obtained 71.4 % and 5.7, respectively. The optimum current generation was observed 0.19 mA. The surface morphology of anode before enriched with microbes was clear surface, while after enriched with microbes was attached by microbes. The removal of COD, pH changes, current generation and morphology of anode surface could be used to assess the EAB in the anode compartment. Keywords: Microbial fuel cell; anode; cathode; electroactive bacteria; pH changes.

Abstract

Turmeric extracts have many benefits, such as an anti-oxidant, anti-inflammatory, and neuro-protector for dementia. The turmeric extracts can be prepared in the form of a thin layer of coated tablets through a dipping method using the dip coating and Simplex lattice design (SLD) methods. The quality of the thin layers of coated tablets is much related to the formulation in the coating process. This research aims to formulate and optimize the coating composition of HPMC, PEG-400, and dip time. Consequently, the TSLT meets the standard requirements. The core tablets were made by using the wet granulation method with the formulation of turmeric extract, erosol, lactose, gelatin, and aquades. Before the core tablets had been produced, the eligibility of granules was initially evaluated based on the standard requirements. Subsequently, the core tablets that meet the standard requirements were printed and replicated. The coating processes on core tablets were performed by dipping into the coating solution in the various duration of dipping times: 5, 30, and 60 seconds. The coating solution consists of HPMC, PEG-400, glycerine, sunset yellow, and distillate water. Then, produced TSLTs were evaluated based on the hardness, friability, and disintegration time. The best optimization process for the mixture of HPMC and PEG-400 indicates a more positive value of R (R = 0.2024).

Abstract

The PEMFC systems are generally operated in acidic environment conditions. Consequently, the metal bipolar plate in the system can easily be corroded. Therefore, the PEMFC performance is decreased along with long-term operation. Based on this fact, a mitigation approach is needed to prevent the corrosion issue in the metal bipolar plate to maintain the PEMFC performance. This work tries to evaluate the corrosion rate of the aluminium bipolar plate before and after being deposited with D-galactose. The electrophoretic deposition (EPD) technique was used to deposit D-galactose on the aluminum surface. To evaluate the effect of D-galactose on preventing the corrosion rate, it was deposited on the surface of the aluminium (AA5052) bipolar plate. The EPD processes were performed by using a potensiodimic in 0.5 M H2SO4. The results show that the optimum EPD process condition was obtained at 0.5 g/l D-galactose for 20 minutes of electrophoretic deposition time. This work indicated that the D-galactose could reduce the corrosion rate of aluminium bipolar plate with an efficiency of 90.7%.

Moreover, it is also used in the field of medicine due to its curcumin bioactive compounds which are useful as anti-oxidants, anti-inflammatory and neuroprotectors for dementia. Therefore, this research aims to formulate turmeric extract tablets that meets physical test standards using the wet granulation method. The extract tablet formulation was made into three formulas, namely F1, F2 and F3, where the composition of aerosol, lactose, gelatin and distilled water of the three formulas was designed based on the results of the parameters in sequence. The printed tablets were then tested using a disintegration, dual friability and hardness tester to determine the disintegration time, brittleness, hardness, as well as uniformity of weight and size. The F3 formulation with the composition of turmeric extract (15 g), aerosol (35 g), lactose (12.8 g), gelatin (0.5 g), magnesium stearate (1%) and aquadest (200 ml) fulfilled the standard physical tablet requirements. Furthermore, the results of repeated tablets (three times) obtained values namely weight (0.616 ± 0.355 mg), diameter (1.334 ± 0.280 cm), thickness (0.518 ± 0.039), friability (0.065 ± 0.074%), hardness (4.635 ± 0.234 kg)) and time destroyed (9,918 ± 4,386). Therefore, based on the results, the F3 turmeric extract tablet formulation shows the quality which meets the tablet physical test standards.Keywords  : Curcumin, Dementia, Turmeric Extract Tablets, Wet GranulationKunyit (Curcuma longa L) merupakan tanaman herbal yang sering digunakan sebagai bumbu masak yang dapat memberikan rasa gurih dan warna yang menarik.

Abstract

Sarisa Merapi is a small and medium-sized micro enterprise (MSME) engaged in food processing such as telang lemon tea, candied salak, dodol salak, sari salak and egg roll. Among these products, telang lemon tea became the choice in this study because of the large number of productions and the relatively low price. In addition, telang lemon tea has health benefits because it contains antioxidants and can be used as a substitute drink for tea. The quality of telang lemon tea is determined by the quality of raw materials, the application of sanitation and hygiene in the production process. But in reality, it is less noticed by business owners. The purpose of this practice is to observe quality control, application of sanitation and hygiene in the production process of telang lemon tea in Sarisa Merapi MSME. The method of data collection is carried out by observation, interviews with staff and employees, documentation and literature studies focused on the process of preparing raw materials, processing, packaging and application of sanitation and hygiene on the production of lemon tea in Sarisa Merapi MSMEs. The process of processing telang lemon tea has three stages, namely the procurement of raw materials, the manufacture of intermediate products and the final product. The results showed that the application of quality control, sanitation and hygiene were quite well performed in the procurement of raw materials, the manufacture of intermediate products, the final product process, packaging and storage. However, in the application of sanitation and hygiene, there were still some problems such as workers did not routinely wear aprons and masks during the production process, the absence of barriers between production rooms. Therefore, Sarisa Merapi needs to pay more attention and evaluate these problems.

Abstract

The volume of municipal waste has become a national problem so far, so a solution is needed to reduce the waste problem. One solution to reduce the volume of municipal waste is to burn waste. However, the combustion needs to be designed to take advantage of the heat generated by combustion. In this study, the process of burning waste with various types of waste materials was carried out. The heat of burning waste is used to evaporate 1 liter of seawater and the seawater vapor is cooled to produce distilled water. The volume of distilled water and the precipitated salt were weighed. The results of the research from the variation of 6 types of waste materials obtained that the type of clothing waste material gave the fastest time, which was 43.75 minutes, the amount of distilled water was 931 ml, and salt deposited as much as 30 grams. The test results on distilled water showed that almost all parameters met the requirements of drinking water and obtained a salt content of 84%. Further processing by adjusting the hardness is needed to process distilled water into clean water and the addition of iodine can be considered to produce iodized salt.

Abstract

Sonochemistry has many applications in biomedical engineering owing to its ability to break chemical bonds. It can also be used to facilitate the preparation of aqueous quantum dots (QDs) dispersions during microemulsion formati on. Cavitation, bubble growth and collapse during sonication facilitate the formation of microemulsions between a solvent and water. Sonication was employed in this study to prepare aqueous copper indium sulfide colloidal zinc sulfide (CuInS2/ZnS) QD dispersions using different solvent systems. The resultant QDs were characterized by UV-vis absorption, photoluminescence, and dynamic light scattering. Hexane was determined to be the best solvent for the preparation of QD dispersions with the resultant QDs (30 nm in diameter) retaining their chemical integrity and >30% of their quantum yield. CuInS2/ZnS QD dispersions in water can be directly prepared without any non-polar solvent and it has shown high quantum yield. Further, it was also shown that less-toxic, which is efficient in labeling tumor cells derived from human liver cancer (HepG2). It’s evident that, sonication was found to be an efficient alternative approach for preparing aqueous QD dispersions without the need for surface modification, or the use of non-polar solvents during microemulsion formation.
