"This paper describes the case study of Semanggi intersection in Jakarta, a dynamic model of emission reduction in the land transportation sector. The urban transportation system is a complex system with multiple variables, feedback loops, and is influenced by social, economic and environmental factors. The proposed model consists of two submodels: Vehicle Fleet and Emission Calculation. The model runs in Powersim Studio software using data from the Indonesia Japan Economic Partnership Agreement, and the Traffic Management Centre of the Indonesian National Police. The test was conducted by developing two scenarios: Business As Usual and Intention. The estimated results to be obtained using the first scenario in 2021 should be 1,113,398 units, while the second scenario is estimated to produce 850,733 units. We hypothesize that the Intentional Approach will have a more significant impact than the Technical Approach, which requires more investment. The Intentional Approach is designed to improve the intention of private car users to switch to public transportation. The Technical Approach to the emission measurement of every vehicle in a certain area is the data of vehicle emission which are usually taken to determine the current condition. This research will no doubt have a positive impact on emission reduction in Jakarta."

This research aims to investigate the antecedents of dynamic capabilities and their influence on company performance in the context of transformation in the Sub-Holding Generation Company of PT PLN (Persero) towards net-zero emissions. There are six antecedents of dynamic capabilities, namely resources, knowledge management and learning, alliance, entrepreneurial orientation, environmental dynamism, and stakeholder pressure, which are tested for their influence on dynamic capabilities and company performance. Dynamic capabilities tested as a mediator between the antecedents of dynamic capabilities and company performance. There were 13 hypotheses tested using partial least squares structural equation modeling (PLS-SEM) with data collection techniques using surveys and a sample of 250 respondents was successfully collected. The structural model is built based on a theoretical framework and then adapted to the research context and with the results of validity and reliability tests. The results of the analysis show that resources do not have a positive impact on dynamic capabilities and dynamic capabilities cannot mediate their relationship with company performance. However, knowledge management and learning, alliance, entrepreneurial orientation, environmental dynamism, and stakeholder pressure have a positive impact on dynamic capabilities and dynamic capabilities can mediate their relationship to company performance. The greatest influence on dynamic capabilities is shown by entrepreneurial orientation, which proves that PT PLN (Persero) in order to integrate, build and reconfigure their internal and external competencies requires a strong entrepreneurial orientation to support the success of the dynamic capabilities process. The analysis results also show that dynamic capabilities have a positive impact on company performance."

ABSTRACT

Nitrogen oxides i.e. NO, NO2, and N2O have an important role in chemical changes in the ozone layer. Nitrous oxide (N2O) is a greenhouse gas that should get attention because it has a great potential for global warming. Biofiltration is the processing of gas pollutants in a medium bed, and pollutants will be degraded by microorganisms. This research aims to develop a biofilter system to reduce N2O emissions using compost as a filter medium, by studying the parameters of biofilter operation as well as the developing of biosorption and the biodegradation model.

The results show that in term of medium characteristics and the performance in reducing N2O, goat manure-based compost medium is better than cow manure-based compost medium, with an average removal efficiency reached 65% and stable up to 200 hours at medium depth of 100 cm, N2O gas flow rate of 88 cm3/minute, and water content of 60%. Biofiltration of N2O with manure-based compost medium can be well modeled by the kinetic based model of Michaelis-Menten for adsorption mechanism, with kinetics parameters VMax, KM, and KN2O 14,847 g/m3.hour ; 0,131 g/m3 ; 1,343 x 10-3 m3/g for bulk compost, and 461 g/m3.hour ; 558 g/m3 ; 0,22 m3/g for pelletized compost."

The increase in greenhouse gas emissions as a result of the increased migration of the population triggered by economic growth in Jakarta brings domino effect against the urban development in the future. For that, it takes a concerted effort to reduce energy consumption and emissions as a key in the sustainable urban development. In response to this phenomenon, the Government of Jakarta has designed regional action plan document which contains strategies for reducing greenhouse gas emissions. This research aims to obtain a model of urban development used to evaluate multiple strategies of greenhouse gas emissions reductions against sectors of transport, households and industries as the three biggest emitters in urban areas. System dynamics theory is used to get an overview of the impact of various policy options in decreasing greenhouse gas emissions. The results of the modelling show that the three scenarios tested, the scenario switches to public transport provide significant impact against a decrease in greenhouse gas emissions."

"This paper aims to: (1) specify factors mediating the effects of consumer animosity towards theconsumers’ willingness to purchase imported products; (2) specify factors mediating the effects of allocentrismtowards consumers’ purchasing willingness on imported product; and (3) examine whetherproduct quality comparison between domestic vis-à-vis imported products moderates the relationshipsbetween: (a) consumer animosity and consumers’ willingness to purchase (b)ethnocentrism andconsumers’ willingness to purchase. A survey was conducted to 209 respondents that have boughtMalaysian products in the past three months and lived in Jabodetabek (Jakarta, Bogor, Depok, andBekasi) area. The result shows that ethnocentrism mediated the relationship between animosity andconsumers’ willingness to purchase; while it does not work as a mediator in the relationship betweenallocentrism and consumers’ willingness to purchase. In addition, product quality comparison doesnot moderate the relationship between animosity and consumers’ willingness to purchase as well asethnocentrism and consumers’ willingness to purchase. Interpretations, contributions, and implicationsfor manager are also discussed.Studi yang bersifat eksplorasi ini fokus pada persepsi dokter terhadap produk farmasi domestikdan multinasional .

"PET-CT is increasingly being employed in the diagnosis of both oncological and non-oncological patients, yet nuclear medicine physicians may have only limited practical experience of rare diseases and may experience difficulty in recognizing and interpreting rare findings. This unique atlas documents a large number of clinical cases that will help practitioners to identify findings and diseases that, though rare, are sufficiently frequent to be encountered in routine practice. Two types of cases are presented: patients evaluated for rare diseases and patients evaluated for standard diseases in whom atypical PET findings were detected. Each reported case includes a brief description of the clinical history, representative color PET-CT images obtained using FDG or other tracers, and a short explanation of the disease and findings. "
