引用

IOP Conference Series: Earth and Environmental Science 2021年第1期732卷

作者： Andrian Putra Wardana Nenny Miryani Saptadji Dimas Taha Maulana Geothermal Engineering Master's Program Faculty of Mining and Petroleum Engineering Institut Teknologi Bandung Jl. Ganesha 10 Bandung 40132 Indonesia

Well casing and cement temperature can change during geothermal production operation. The change of temperature occurs because of the heat transfer from the geothermal fluid to the formation. The heat transfer occurs because of the temperature difference in geothermal fluid and formation. The heat of fluid moves to the casing, cement, and formation through convection and conduction. This research aims to develop the heat transfer model in the steam production well, predict the steam heat loss and its effect on every 100 m well increment, and predict the well casing and cement temperature distribution and their effect on every well segment. The heat transfer model is an analytical calculation model developed to be the base of the calculation of heat loss and a temperature drop of well casing and cement. This model was developed for the calculation of heat loss in steam production well. The model was compared with a simulator to test the suitability. The fluid flow pressure drop and well lithology were considered in this model. The heat loss was very low during the steam production. The heat loss could be higher, along with the formation temperature drop. The material thermal conductivity and the well segment's layer thickness could affect the steam heat transfer in the production well.

作者： Kustiani R P Khidmat Architecture Study Program Faculty of Engineering Universitas Bandar Lampung Indonesia Architecture Study Program Department of Regional and Infrastructure Technology Institut Teknologi Sumatera Bandar Lampung Indonesia

Building performance can be improved by investigating and evaluating previews of occupant behavior. Post-occupancy evaluation (POE) is a design analysis method used to direct and evaluate the physical and social elements of inhabited buildings. In recent years, the Ministry of Public Works and Public Housing grants student dormitory building to several Indonesian universities. In 2017, Institut Teknologi Sumatera (ITERA) Bandar Lampung Indonesia has been granted two of those student facilities. The building has been operated for three years. The student dormitory considered has one type of building that has a high capacity occupation. This research aims to measure user satisfaction and evaluate building facility and its implication to student learning effectively using the POE method, specifically human behavior aspects. During this time, POE is more focused on building physical behavior that includes energy and thermal aspects. In this study, the author tries to raise aspects of human behavior as an essential element supporting the sustainability of the building. The survey conducted using eight variables: territoriality, privacy, interaction, perception, crowdedness, adaptability, durability, and comfortability. This research focuses on measuring only female student dormitories. One hundred eighty-two respondents were involved in the survey. The result shows that the majority of respondents feel quite satisfied with all the variable measure. This finding can be a reference to improve the design consideration for future student dormitory design.

作者： U R Irfan A Maulana I Nur M Thamrin M Manaf Geological Engineering Department Universitas Hasanuddin Gowa Indonesia Mining Engineering Department Universitas Hasanuddin Gowa Indonesia Urban and Regional Planning Study Program Bosowa University Makassar Indonesia

Settling-pond treatment systems have been applied in the base-metal mining area at Sangkaropi, South Sulawesi, Indonesia, before being discharged into the Koyan River through the agriculture area. This study aims to conduct a valuation of pollutant Pb, Cu and Zn in areas impacted by base-metal mining in sediment materials as a sensitive indicator for monitoring contaminants in the aquatic environment. Sediment sampling location, the first is in the upstream before the mining location, the second is located in the mining area to settling pond, and the third is in the area after settling-pond to the agriculture area. The concentrations of heavy metal were analyzed using uses AAS method. The assessment is performed based on the value of contamination degree, enrichment of heavy metal pollutant and ecological risk. The arrangement of the average frequency of heavy metal concentrations is Pb>Cu>Zn, which Cf and I-geo values have the almost same behavior. All metal in the upstream and agriculture site is classified as a low category, the Cu on the second and third sites is moderate. The assessment results from this study represent that Pb has a considerable ecological risk category value. However, polluted-Cu are categorized moderately need to be cautious, because metal enrichment comes from mineralization bedrock in the river. Therefore, the result of this study shows that geologic data, especially mineralized bedrocks associated the heavy metal concentration, should be taken into consideration in land-use planning policy in areas that have been impacted by mining and in the assessment of environmental health impacts.

DC motor is a type of motor that is widely used in industry, electronics and supporting components for some electronic equipment or instrumentation. But now the PID controller is still widely used in various industrial sectors, this is due to its toughness to overcome various problems that exist in the industry. But there is one drawback that is the tuning method, the tuning process must be done by trial and error. More tuning procedures done manually by trial and error method that the result is not necessarily true. To overcome these problems required an alternative approach that can achieve a relatively better value and faster to perform the tuning process. In this case the alternative method used is tuning with Ziegler Nichols. Based on the simulation performed with the controlled torch, the value of the disturbance with the controller Kp = 3,6, Ki = 2,857 and Kd = 1,134 happened to the motor rotation at the lowest interference occurred at 1818 RPM while the highest rotation disturbance reached 2177 RPM from the nominal rotation speed of 2000 RPM for 80 seconds and suffered a friction coefficient of about 20 seconds.
