Abstract

This research develops a monitoring tool for urban plan-process based on Life Cycle Analysis by Lourenço. A special project of urban waterfront revitalization is proposed as a contribution to legitimize the LCA model. This research also proposes the influence and the success key factors of its behavior plan-process.The model is tested through benchmarking for six waterfront cities in South Europe. Bilbao in Spain, Genoa in Italy, and Lisbon in Portugal are considered as the success projects since the urban strategy has a strong link with the urban waterfront area notified by the high intensity of the cycle for each phase. Porto and Viana do Castelo in Portugal are considered as the success projects which have a similar behavior for the action and living phase which might be due to the same project under national policy and the projects touch economic and social opportunity of the people. Aveiro in Portugal shows rupture in the beginning, followed by high intensity in the next period which has similar behavior with ideal behavior of LCA model.This research shows the applicability of LCA Model to monitor waterfront revitalization projects and enables the discussion of conceptual issues related to the legitimizing of LCA and the present contribution. The behavior of urban waterfront area and the time dimension can be monitored and the influenced factors of the behavior can be noticed with the success key factors, those are: Planning: does the urban waterfront become the focus of the city planning? Action: does the project persistence in the design proposal? andLiving: does the urban waterfront touch social, culture and economic of the people activities?.

Abstract

Ground response analyses are used to predict surface ground motions for development of design response spectra, to evaluate dynamic stresses and strains for evaluation of earthquake hazards, and to determine the earthquake induced forces that can lead to instability of earth-retaining structures. The effects of local soil on ground motion are commonly evaluated by performing numerical analyses either in frequency or time domains.In order to evaluate the differences between frequency and time domain analysis, several analyses were conducted for homogenous stiff soil deposit with respective codes which are SHAKE and D-MOD2000. Linear and non linear analyses have been conducted. The non linear analyses with D-MOD2000 code have been carried out by using different frequencies in the Rayleigh damping formulation, i.e. fundamental and predominant frequency. For linear, PGA 0.1g is used in the analysis while for non linear PGA is scaled into three different value of 0.1, 0.3, and 0.5g.The results for both linear and non linear approach are similar. For the non linear analyses, it is shown that the curves derived using predominant frequency perform better than those using fundamental frequency. Main differences are for non linear approach where the differences between two codes are higher for higher input motion. As the calibration using predominant frequency between the two codes perform good, the respective codes are applied to evaluate soil response in Sant’ Agostino and San Carlo, in terms of PGA, due to May 20th 2012 Emilia Earthquake. There are 139 accelerometric station recorded strong motion. In this analysis, we consider one record which is in Mirandola station, the closest recording station where the Magnitude in epicentral area was 5.9 and 5.8 in Mirandola station. The recorded surface motion in Mirandola is transferred to the bedrock in 112 m depth and used as input motion for the two evaluated sites, San Carlo village and nearby municipality Sant’Agostino on 17 km distance from Mirandola station. The preliminary data presented here shows the PGA recorded in the bedrock of Mirandola station is 0.75g, while in Sant’Agostino and San Carlo is 0.92g and 0.81g.

Abstract

Hospital operations have the potential to produce waste, especially wastewater, which can cause environmental pollution. Therefore it is necessary to control the disposal of liquid waste that is discharged into the environment. It is required to reduce the pollution of wastewater management is excellent and appropriate legislation. Research methodology starts from the data observed laboratory test results for samples of hospital wastewater. From these data, it is known that the levels of phosphate and ammonia still do not meet quality standards following the Decree of the Minister of Environment No. 58 of 1995 regarding effluent standards for hospitals. Further research is limited only focused on decreased levels of phosphate and ammonia in hospital wastewater.Data research includes a phosphate concentration of outlets as a pilot study. The subsequent wastewater will be divided into seven-bath, three-bath containing wastewater and water hyacinth plants with a density different in each basin ie density of 60 mg/cm2, 90 mg/cm2, and 120 mg/cm2, three baths containing hospital wastewater and Azolla plant density of each tub 60 mg/cm2, 90 mg/cm2, 120 mg/cm2, and the control tanks containing wastewater without a given crop. Based on the results obtained, phosphate levels can meet the fastest quality standards for four days on a tub of hospital wastewater and water hyacinth with a density of 120 mg/cm2 and all of a tub of wastewater hospitals and Azolla. For ammonia takes the fastest four days, this happens in a tub filled with water hospital waste, and water hyacinth with a density of 120 mg/cm2 and the entire tub of wastewater hospitals and Azolla.

Abstract

The depletion of non-renewable energy reserves and increased awareness of environmental damage caused by fossil-based fuel use have encouraged the world’s efforts to develop and utilize new and renewable energy sources, including in Indonesia, especially in the special region of Yogyakarta. The potential for wind power plants can be developed in 3 districts in the southern part of Yogyakarta, bordering the Java Sea, to be converted into hydrogen through an electrolysis process. The three research locations were Bugel Beach in Kulon Progo, Pandansimo Baru Beach in Bantul, and Baron Techno Park at Baron Beach in Gunung Kidul. The selection of the most optimum location was made employing the Analytic Hierarchy Process (AHP) method by considering three factors, namely technical, location, and socio-economic factors. The first factor includes the potential for electricity generation from wind power and the available land area. The second one consists of sub-factors, namely access to the location and the distance to the PLN electricity distribution line. Then the last one includes conflicts with tourism and the economic activities of the surrounding community. After obtaining the most suitable location, planning is carried out for the wind farm that is built, the amount of electrical energy produced, the cost of generating electricity, and the cost of producing hydrogen from the electrolysis process. Pandansimo Baru Beach is an ideal location, with an average wind speed of 4.833 m/s. Five Vestas V80 2000/80 wind turbines were selected according to the available land. The annual electrical energy that can be produced from this system is 161,677,216 kWh/year with a generation cost of 0.118 USD/kWh and is capable of producing 230,960 kgH2 of hydrogen at 4.35 USD/kg.

Abstract

The COVID-19 pandemic as a global pandemic on 2020 has encouraged the Indonesian Government to establish pandemic response policies in many provinces. The policies that had been restricting mobility during the pandemic showed significant impacts in many aspects in the Special Region of Yogyakarta. A shifting pattern in electricity consumption can be seen as the growth of economic sectors in the GDP encountered contraction after the decline of community mobility. Electricity demand forecasting is required to analyze the impact of the COVID-19 pandemic by applying three scenarios, specifically an unlikely pandemic scenario or Business As Usual (BAU), moderate scenario (MOD), and optimistic scenario (OPT). Also, the household, industrial, business, social, and public sectors are analyzed in order to see the shifting pattern in electricity consumption through the scenarios that have been given. Energy modeling is conducted with Low Emission Analysis Platform (LEAP) software to analyze electricity demand forecasting from 2019 to 2030 based on the three scenarios. The results show that the electricity demand in 2030, according to BAU, MOD, and OPT scenarios, in the amount of 5,301.58 GWh, 4,489.11 GWh, and 4,648.12 GWh, respectively. According to the MOD and OPT scenarios, the electricity demands of the household and industrial sectors will increase relative to the BAU scenario. Meanwhile, according to both scenarios, the electricity demands of the business and social sectors will decrease. In the public sector, the MOD scenario shows the decline of electricity demand relative to the BAU scenario, while OPT scenario shows the opposite.
