Abstract
Lung agenesis or aplasia is an extremely rare congenital anomaly. It is estimated at 34 per million live births. The etiology of thes disorder has not clearly known. Failure of development of the primitive lung bud leads is the cause of this condition. In half of these cases, it has been reported in association with other congenital defects such as congenital malformation of the cardio-vascular, skeletal, gastrointestinal or genitor-urinary system. This condition is usually diagnosed during childhood. Some patients with lung agenesis may suffer from recurrent respiratory distress, dyspnea, and lung infections. We report a case of a 1-month 28 days old male infant with right sided lung agenesis association with spina bifida as other congenital defects presented to us with recurrent severe respiratory distress. This case emphasize the importance of investigating any possibilities of others congenital abnormalities when the patient presented lung agenesis or aplasia.

Abstract
Safe treatments of spent car battery must be conducted because of its Lead (Pb) content that can be a toxic pollutant especially if it gets to drinking water supplies. The objectives of this study is to determine the effects of adsorbent types (zeolite and activated carbon) and concentrations (0%, 5%, 10%, 20%, and 25%) in reducing the Pb-content in waste water from spent car batteries recycling process. Imitated waste water samples was prepared by soaking the contents of a used car battery, such as plates and acid, in four liters of water for ten days, which resulted in an initial Pb-content of 8.02 mg/L and pH of 2. Adsorbents were prepared chemically and physically, and were then added to 100 ml leachate samples followed by stirring at 150 rpm for one hour. The volume of 0.5 M NaOH needed to neutralize the pH was 35.7 ml for 10 ml of waste sample. The lowest final concentration of Pb-content in spent car battery at 0.239 mg/L was achieved by adsorption using 25% activated carbon.

Abstract
In recent years circular economy has been widely discussed throughout the world as a solution to the problem of resources efficiency and also environmental problems, especially regarding waste. The construction industry is one of the largest waste-producing industries, even 30% of waste on landfills is construction waste. The application of circular economy in the construction industry has many interrelated and dynamic variables that change over time. This study aims to identify the variable of circular economy and analyze the pattern of its relationship using system dynamics method. The variables were obtained from in-depth literature review and interviews, including management performance, low-waste technology, and behavior. Then from these variables a causal loop diagram is created. This diagram describes the relationship between variables of circular economy. For model validation, a multi-storey building project in Surabaya is used as a case study. This study produces a model that can be used to estimate the volume of construction waste of waste with an accuracy of 86.12%. Scenario simulation results show that worker variables can reduce the volume of waste construction up to 7.91%, higher than other variables.

Abstract
Numerical studies of thermal decomposition of Palm Kernel Shell (PKS) have been conducted in a fluidized bed reactor under atmospheric pressure of nitrogen as fluidization gas. To investigate the effect of temperature, the pyrolysis temperature was varied in a range from 400 oC to 650 oC. Furthermore, the effect of PKS feeding rate was also studied in a range 300 g/h to 1500 g/h combined with variations of nitrogen superficial velocities. It was found that the increasing of temperature results in the greatening of conversion efficiency and non-condensable gas product yield. The maximum liquid/tar product yield was obtained in 500 oC, namely 60.5%. The increasing of PKS feeding rate led to the reduction of conversion efficiency due to the thermal energy shortage for the decomposition process. However, the increasing of PKS feeding rate could reduce the non-condensable gas product with the unsignificant change in liquid product yield. The increasing of superficial velocity of nitrogen favored the shorter of residence time resulting in the increasing of tar product yield.

Abstract
In Citarum River, West Java, Indonesia, there are three serial reservoirs successively spreading out from upstream to downstream, namely Saguling Reservoir with the volume of 875 million m3and electrical energy production of 700 MW, Cirata Reservoir with the volume of 2,156 million m3 and electrical energy production of 500 MW, and Jatiluhur Reservoir, the most downstream, with the volume of 2,451 million m3 and electrical energy production of 150 MW. Jatiluhur Reservoir also provides supply for irrigation of 260,000 ha areas and drinking water industry with average inflow of 100m3/s. Those reservoirs have highly fluctuated with maximum water level 5 m per month. This condition occurs as sharing-non-sharing system is applied. Although this fluctuation is still in a normal condition, it affects the stability of reservoir slope. This study discusses about the validation of linear method to reach an optimal value of reservoir production in terms of electrical energy. The primary reservoir inflow data used was from 1988-2000, while the demand data was taken from 1992-2000, Cascade reservoir technique data was based on the existing data in 2000, Stochastic analysis was used to determine the inflow of 2000-2005 generation, while demand analysis was carried out using regression analysis. Multi-reservoir optimization analysis is carried out with linear simulation programs to obtain energy or fulfillment of demand every month, while demand for irrigation in the Jatiluhur reservoir is needed as a top priority supported by Saguling, Cirata and Jatiluhur reservoirs as the next priority. The result of optimizing cascade reservoir from 2001-2005, with initial period of operation on April obtained an average electrical production of 4,996.5 GWh, shows that the realization of average electrical production is 4,141.96 GWh. Besides, the average of demand is 4,996.8 MCm while the average supply is 5,806.2 MCm.

Abstract
Advertising is utilized to provide information to the community in order to attract attention and move the desire to buy goods so as to increase the number of sales of goods or services. Advertising is generally made and placed in strategic places that can be seen both morning and night. To see billboards at night, a good light is necessary. This lighting uses floodlights that require considerable electrical power. Inverters with the DDS method can be utilized to reduce the electrical power requirements for illuminating billboards by reducing the voltage by changing the modulation index on the PWM generator. From the simulation results with a 220 Watt lamp load indicates the output waveform in the form of pure sinusoidal voltage. The output voltage is 223 volts and the current is 2.23 A at a frequency of 50 hz with a modulation index of 0.8. The condition of illumination light is brightly normal, while the 0.6 modulation index produces a 170 volt voltages and a current of 1.7 A with dimmed lighting. Electricity consumption of lighting using an inverter has decreased by 24%.

Abstract
An ocean tol has been built in Indonesia. Thus, it is needed many ships to fulfill this programs. The marine ships are operated on sodium chloride (NaCl) environment, so that the ship materials have to be able to withstand the environments. The purpose of this study is to characterize the crack propagation of AA5083H116 and ER5356 electrode-welded materials under static loading in an environment containing 3.5 wt% of NaCl. This study was started with construction of the bending test equipment in accordance with the Brown and Beachem and ASTM E 1681. The IZOD notched specimens used in this test were prepared using electrical discharge machining (EDM) according to the ASTM E-23. The test was carried out at constant loading of 40 N with time variations. During the loading, the specimens were immersed in a 3.5 wt% of NaCl environment. The deflections and times during loading were then recorded and finally the specimens were fractured using liquid nitrogen. The crack lengths were measured by means of optical microscope in order to characterize the crack propagation vs stress intensity factor. The fracture surfaces of the specimens were examined using SEM-EDS to characterize their fractography and chemical elements. The results show that the crack propagation of welded materials of 10 mm/s speed travel was lower than the other and the fracture surface indicates intergranular fracture, while the chemical elements shows there are of Mg, Na, Cl elements on the fracture surface.

Abstract
The existence of the millennial generation in the digital era today has disrupted various things. Millennials have changed everything. Millennials have penetrated the public sector, formed new work patterns, managed digital-based activities, and optimize digital media channels as a means of communication, work processions, and publicizing their performance. Government bureaucracy is increasingly dominated by millennial civil servants (ASN). Will its existence disrupt the bureaucracy, turn it into a humanocracy or directly adapt it as a digitocracy? This study aims to describe the existence of millennials ASN and its work in the government bureaucracy. The method used is descriptive-qualitative. Data analysis through stages of data reduction, data presentation, and conclusion/verification. Studies show that the existence of massive millennials ASN in government organizations will disrupt bureaucracy by reforming management and work patterns becoming more human and digitally based. This situation created a humanocrats who shifted the role of bureaucrats and even adapted it to become a digitocrats. The study concluded that the development of digital technology would shift the working pattern of millennials ASN to be more humanistic through the utilization of digital devices. It is recommended that the Government should facilitate the transformation of bureaucracies and formulate adaptation strategies into digitocracy.

Abstract
The Comoro river basin is one of the watersheds in Timor Leste with an area of 212 km2. The Comoro river and its tributaries are the main surface water source for clean water needs in the city of Dili. The purpose of this study was to estimate the availability water from 4 sub watershed of Comoro using the F. J. Mock model. The Mock method is rainfall-runoff model and was used when measured discharge data is not available. The input of this model are rainfall, potential evapotranspiration, soil moisture and watershed characteristics. The result of calibration and verification of model in the upstream of Comoro watershed indicate that the value of the correlation coefficient were 0.8 and 0.7 while the volume error (VE) were 0.05 and 0.04, respectively. The parameters that was produced in the calibration of the Upper Comoro watershed are then used to estimate the discharge in the Beemos, Maloa, Kuluhun and Becora sub-watersheds due to no observational discharge data available. The dependable flow 90 % from the total of the four sub-watersheds is 0.06 m3 / sec. This shows that surface water availability is only 1,718,053.808 m3/year to meet domestic and non-domestic needs in Dili.

Abstract
Demolition needs special attention because the planning process is complex and has high risks (Yeheyis, Hewage, Alam, Eskicioglu, & Sadiq, 2013). In decision making, practitioners are faced with various conditions that influence the choice of demolition methods. This study aims to develop an optimal model for building demolition methods according to building characteristics. Identification of criteria is done by in-depth literature review and interviews with practitioners who have carried out demolition in Indonesia. The five criteria used in this study are health and safety, the presence of hazardous materials, the shape and size of the structure, requires structural engineers and workplace security. Furthermore, neurofuzzy is used to make the optimum demolition method decision. Fuzzy is used to integrate quantitative and qualitative variables while the Neural Network is to make decision making rules. For validation the model uses 13 building condition that have been demolished and use case studies. Simulation results show that the proposed model is able to make accurate decisions on the selection of demolition methods.
