Abstract

Biodiesel is synthesized through a transesterification reaction with the help of a catalyst and generally uses a homogeneous catalyst. Heterogeneous catalysts can be synthesized from waste biomass such as avocado peel through a calcination. The purpose of this study was to examine the effect of variations in calcination temperature (550, 650, and 750oC) on the performance of the catalyst for biodiesel production and to analyze the effect of differences in the amount of catalyst (4, 6, 8, and 10% by weight of oil) used in the transesterification process on biodiesel yield. The catalysts were characterized by XRD, SEM-EDX, and FTIR. The results of the characterization of the catalyst showed that the dominant active phase of the catalyst was potassium (K). The highest biodiesel yield was obtained when using avocado peel ash as a catalyst which was calcined at a temperature of 650oC and using 6% catalyst by weight of oil. In the transesterification reaction the composition of the biodiesel product was analyzed using GC-MS and resulted that the palmitic acid was the most abundant composition in biodiesel. The biodiesel products produced were characterized for its density, viscosity, and acid number and have met the standard of SNI 7182:2015.

Abstract

Technological developments that increase the increase in electronic waste (e-waste) significantly. In Indonesia, the method of treating electronic waste by fire is not appropriate to apply, because electronic waste contains metals and will cause dangerous air pollution (for example: lead pollution). Electronic waste processing is different from organic waste that can be processed into fertilizer. Therefore, this condition can be categorized as an important problem, so it requires smart solutions that are fast and precise in processing. Handling this waste can be solved through several methods, namely e-waste banks and art integration. This method prioritizes artistic value, creativity, function, and in-depth knowledge of the waste, so that it can also take advantage of organizations or businesses that will bring profit and be environmentally friendly. This has also received support from the government through a program commonly known as Small and Medium Enterprises (UKM). The components that are usually buried, melted down, and destroyed will be sorted again based on their physicality so that it will facilitate the process of making art.

Abstract

Acid mine drainage is one of the significant negative impacts of  mining activities that can result  in environmental degradation. Waste rock is  mine waste that is found in large quantities and can produce acid mine drainage (AMD). This study aims to identify  waste rock which has  the potential to generate acidity (PAF) and do not generate acidity (NAF) in the Barani and Ramba Joring pits and the application of the encapsulation model in  tailings dams. The research method with the encapsulation model is a simple method designed in tailings dams to encapsulate the PAF with the NAF. Rock characterization and geochemical analysis will result in the rock being classified  as  PAF and NAF in both wells . The data used for this study are drilling data (cutting) data that include rock lithology and chemical quality (NAPP and NAG) data. The results identified that the PAF was dominant relative to the  NAF  both wells  and the waste rock in the Barani pit was at a  higher risk of producing acidity than the Ramba Joring pit. Measurements of oxygen diffusion and surface water quality indicated that encapsulation of waste rock in the tailings dam may  prevent the formation of acidic mine drainage

Abstract

Noise level in the classroom is a factor affecting the learning process. This study aims to determine the level of indoor noise of a private university campus in West Jakarta. Measurements were made using Sound Level Meter that can record the noise level every second with accuracy up to 0.1 dBA. Sampling was carried out in a number of classrooms in an empty condition, closed door, and air conditioning system either in off or on position. Classrooms are distinguished based on the condition of the wall, namely the window facing the outside environment and massive walls without windows to the environment. The measurement results indicate a significant difference in noise level at a 95% confidence level in an empty classroom when the air conditioning system is not functioning and when the system is running. Differences also occur in classrooms with and without windows to the environment. The difference shows that the classroom in an empty condition can experience an increase in latent noise level due to the operation of the air conditioner between 5.78-16.49 dBA. Increased noise from the environment including the highway is about 3 dBA for classrooms located on the 5th floor, with a horizontal distance about 100 meters from the highway and has thick and permanent glass windows.

Abstract

The spread of contamination to ground water and surface water from excessive fertilizer become major concern. Therefore, the aim of this study was to develop slow release fertilizer using urea fertilizer and kieserite in polyacrylamide-cellulose composite.Composite preparation was carried out by two variables that are kieserite mass variation and cellulose mass variation. The compositequality as slow release agent is measured by characterizationanalysisincluding porosity, swelling power, adsorption of urea, and urea released profile from composite compared to urea granules and tablets. Functional cluster and bond was investigated by FTIR (Fourier Transform Infra Red). Adsorption and desorptionpower of composite was determined by UV-Vis spectrophotometer with Nessler method. Result of variations in kieserite shows that the addition up to 3 grams kieserit mass causes an increasing in the swelling and porosity.Addition of cellulose increased the swelling power of composite but it lowers the porosity of the composite. Testing adsorption and desorption performed on the composite of the best(of 2 g kieserite, 0,15 g cellulose, and kieserite mesh -60 +80). The adsorption of urea by composite is 2.3115 g urea/g composite. Release profile of urea from composite is slower than the urea granules or tablets. As result, polyacrylamide-kieserit-cellulose can be developed as slow release fertilizer to increase fertilizer using efficiency and to avoid excessive water and ground contamination
