Investigasi Difusi pada Sistem Urinari untuk Gangguan Fungsi Ginjal Model Empat Kompartemen menggunakan Metode Monte Carlo
Get PDFKidney is a pair of organ in our urinary system that function to filter blood and urine establishment through filtration, reabsorption and secretion process.Formation of urine is done through one of processes, named tubular reabsorption. This process is a process of diffusion, passively and facilitated. The process happens in tubular reabsorption in kidney can be simulated by using Monte Carlo Cell simulation. Making model of 4 compartments consist of blood vessel, 2 kidneys with one kidney experiencing decreased function of kidney and bladder. Two kidney compartments with one of it experiencing decreased function affect the diffusion process that happens in substance reabsorption process in kidney.The purpose of this research is to study the diffusion process which happens in kidney by selecting several fixed variable and indicators which will be inspected by using Monte Carlo Cell simulation. The use of Monte Carlo Cell simulation enable to try any probabilities that occur in diffusion process of filtration, reabsorption and secretion process in kidney. The result of this research shows that the fewer number of molecules, the slower the molecular displacement and also the fewer number of surface molecules, the slower the molecular displacements

Environmental Pollution Impact Analysis on Faecal Sludge Process Using Life Cycle Assessment and Analytic Hierarchy Process
Get PDFThe processing of fecal sludge in the IPLT is an advanced processing activity because the sludge in the septic tank has not been properly disposed of into the environment. After all, it still contains high organic loads. IPLT Kota Batu is the object of research. It aims to determine the environmental impact caused by the treatment of sludge in the IPLT Kota Batu with the Life Cycle Assessment Method then provide an alternative in reducing the impact with the Analytic Hierarchy Process Method. Life Cycle Assessment is a method for analyzing the environmental impact of a product throughout the life cycle. Stages of life cycle assessment (LCA) are goals and scope, life cycle inventory, life cycle impact assessment, and interpretation data. An alternative selection is then made to reduce the environmental impact using the Analytic Hierarchy Process (AHP) Method. AHP is describing a complex problem into a result that is represented in a multi-level structure. AHP stages are input goals, criteria, alternatives, weighting, and priority scale, producing the recommended answer or decision. From the LCA method, it was found that the emission load released into the environment in the treatment of sludge was in the form of CO2 emissions, energy emissions, and potentially disappearing species fractions of 3.948,935 kg CO2/year, 1.100.334,84 MJ, and 3.624,647 PDF.m2.y. The use of this method can find out that the treatment of sludge in the IPLT Kota Batu has an environmental burden and impacts the phenomenon of global warming, non-renewable energy, and aquatic eutrophication. The best alternative to reduce emissions in the treatment process of sludge in the IPLT Kota Batu is to perform maintenance treatment on a scheduled basis
HOUSE DESIGN VARIABLES IN PROVIDING INDOOR THERMAL COMFORT IN WARM HUMID CLIMATE
Get PDFBuilding design variables in warm-humid tropics have been widely studied using various approaches. In the climate, achieving low inside air temperature is challenged by high relative humidity for providing comfort. Therefore, this study aims at finding various ways in house design to achieve naturally indoor thermal comfort. In this case, house design variables were analyzed by using TAS (Thermal Analysis Software) building simulation software as well as supported by literature reviews. The simulations undertaken in this research used simple models to which are applied some house design variables to determine the best way to reduce inside air temperature. The simulation used the weather data of Banda Aceh city as the case study. In this article the house design variables are discussed in the following aspects: shape, house orientation, ventilation, shading, building materials, and environmental aspect.
WATERFRONT DEVELOPMENT STRATEGY OF THE OLD KALIMAS PORT BASED ON THE ZONING OF TANJUNG PERAK PORT
Get PDFWaterfront area is a special place in major cities around the world. Place to work, play or fulfilling a sense of curiosity. The old Kalimas Port is also no exception. As well as waterfront areas in other major cities, as a place for change (transition), with so many maritime facilities and a few new activities to attract people to the waterfront. When future generations are look back on this transition as historical moment of Kalimas River, they who are live today would feel that too many waterfront areas are separated from the public for a long time. The challenge of the waterfront development area is not only to help change the Kalimas riverfront as far as 2.5 km, to be a place to reflect modern traditions and a sense of place, but also take into account the history as an important role.By using a qualitative and descriptive method, the study aims to make a comparative analysis from some of the successful waterfront development concepts with the same character of the region, the old industrial riverfront area.The results are the waterfront development strategy, particularly in the Old Kalimas Port which is also part of the Tanjung Perak Port in Surabaya. It requires some special criteria, the vision and missions of the waterfront planning and development concepts. While in the old Port development strategy, in terms of the physical condition of the area and the Port authority policies, formulate zoning strategies as a macro strategy in the future sustainability of the region. The zoning strategy develop three micro zones; the old Port zone, recreational zone and commercial zone. The three zones have their own strategies which will be mutually support the sustainability of economic, social and cultural sector
Preliminary Study of Using KY-038 Sensor Based on Arduino UNO and LabView to Determine the Pulse Rate
Get PDFThe KY-038 sensor module is designed using Arduino UNO and LabView to allow human pulses. The experiment was carried out by making a design consisting of the KY-038 sensor module, Arduino UNO and LabView on a computer. LabView software is used to display pulse wave patterns. Measurement of the pulse will involve human objects with variations 3 namely relax (sit), sit and after running in place. The experimental results show that the different activities affect the voltage released on a chart that has a rating of 3 - 3.5 V. The more activities that are carried out before retrieving the pulse data, the greater the voltage that is read on the LabView results graph. After running in place, the value of the voltage and pulse are 3.5 V and 97 beats per minute, respectivel
