Significance
Little is known about the neural dynamics underlying previously reported associations of organophosphate (OP) pesticides with adverse neurodevelopment. We used functional near-infrared spectroscopy (fNIRS) to examine cortical brain activation in relation to residential proximity to OP use during pregnancy among 95 adolescents enrolled in a longitudinal birth cohort. We found that prenatal OP exposure was associated with altered brain activation during tasks of executive function. We also found sex differences for OPs and brain activation during a language comprehension task. Use of fNIRS, an inexpensive and easily accessible technology, enhances our efforts to assess the impact of environmental exposures on brain function.

Significance
Air pollution via phototoxic polycyclic aromatic hydrocarbons (PAHs) is a major risk factor for human health. While in vitro observations and in vivo correlations suggest a detrimental effect of PAHs at physiological concentrations, in vivo observations of the structural impact of PAHs are scarce. Here, we use transmission electron microscopy on human hair fibers containing known concentrations of 25 biomarkers of PAH exposure. We show an increased structural degradation of the hair fiber over time, when increased PAH concentrations are present. Moreover, we show that exposure to UV radiation explains part of the increased damage in more contaminated fibers. Our results point toward possible detrimental effects in other human tissues at physiological concentrations of PAHs.

Significance
Copper is a required metal nutrient for life, yet its altered homeostasis is associated with many diseases. Thus, to develop new methods to help decipher copper biology, we present an activity-based ratiometric fluorescence resonance energy transfer (FRET) probe that exploits a biomimetic, copper(I)-dependent cleavage reaction to enable imaging of loosely bound, labile copper pools in cells with metal and oxidation state selectivity and a self-calibrating ratiometric response. Application of this technology to cellular models of cancer reveals that oncogene-driven changes in the metabolism of glutathione, a major cellular redox buffer, leads to a labile copper(I) deficiency. This work establishes the relevance of copper dysregulation to cancer metabolism and presages further opportunities for activity-based sensing in studies of metal biology.

Published: August 2019

Significance
The mosquito is the world’s most important vector for transmission of infectious diseases, and chemical agents now used for bite prevention can have environmental or human health side effects. This work explores a nonchemical method for mosquito bite prevention based on graphene, the atomically thin sheet of carbon atoms, as a potential barrier material. We show that multilayer graphene films in the dry state completely inhibit biting by preventing mosquitos from sensing skin- or sweat-associated chemicals used to locate blood meals. In some cases, the graphene films also act as mechanical barriers to the penetration of the mosquito fascicle, its feeding apparatus. The results can guide development of graphene protective technologies on skin or within smart fabrics.

Authors: Fitrianingsih D , Ghozali A 
Published: August 2019

Abstract
Spatial Plan of Balikpapan City in 2012-2032 decides Karang Joang Village as a strategic area of economic interest. As a consequence, the development of regional infrastructure was built to support the emergence of new centers of activity, such as State Universities, highways and regional industrial area. Therefore, the price of land in Karang Joang has doubled over the past two years. High land prices tend to be used for commercial activities. On the other hand, zoning activities are needed to ensure the harmony of space and control the growth of land outside of its designation. Land use that is not in accordance with the plan as a result of high land prices can cause many land conflicts such as land speculation, inappropriate land use, and other problems. A land pricing model is needed as a fundamental for zoning of spatial utilization activities to minimize land conflicts. The land price model can also be used by the government to make policies or space planning in accordance with the development of land prices. The Euclidean distance method from GIS was used to identify land characteristics against factors affecting land pricing and regression analysis to construct land prices models. We found that there were nine factors that influence land prices, namely the distance of land to government centers, markets, universities, hospitals, arterial roads, collector roads, industrial areas, availability of electricity services and land use. Among these factors, the availability of electricity services contributed the largest increase of 252,234 IDR and the land that close to the industrial estate tended to decrease by 648 IDR/m2.

Abstract
Public transportation is important facilities to service the mobilization of citizen in urban activity. Bus Rapid Transit (BRT) is one of the modes considered suitable for developing cities such as Semarang. To ensure the sustainability of the BRT, good planning and operation and maintenance are required. In the operation of BRT eco driving behavior is believed to save fuel up to 13% and keep the fleet condition safe and reliable. This research is intended to know the behavior of the driver in operating the BRT. From driver behavior and onboard survey can be classified the level of eco driving the operation of BRT in Semarang. An eco driving level assessment was conducted on a sample of the BRT fleet. The analysis is done by making the level of eco driving using spatial analysis GIS. It divided into several levels that is high, medium and low. In the other hand, the topography is believed caused of the driver behavior. Furthermore, spatial analysis is done to map the areas that have variance slope. From the mapping results can be concluded which areas have low levels of eco driving and the slope characteristic. From these conclusions, recommendations for BRT performance improvement can be formulated.

Published: August 2019

Abstract
Gender-based poverty alleviation program is important for performing good governance as it is ensuring the achievement of program road map related to development outcomes. It was established that the lives and realities of women and men, girls and boys are often shaped very differently. Therefore, it is necessary to compile, analyse and publish data separately for both sexes. An example of disaggregated data method is poverty alleviation program at Sumogawe village, Semarang which uses the asset based poverty reduction program method. This program looks at observations of human, natural, financial, infrastructure and social livelihood assets. In its implementation, this approach method is able to describe the relationship between the usages of these assets in improving the quality of life of the poor. But there are several pitfalls related to gender-based disaggregated data. One, it has not been clearly identified how the roles, treatment and response of each population based on age and sex in utilizing these assets. Secondly, asset management has not been linked to gender indicators set by Bappenas in 2012, as one of the effectiveness indicators of poverty alleviation program achievements. Third, it has not been identified how an explanation of the relationship between each livelihood asset in the context of the hierarchy of utilization at the level of individuals, households and communities in relation to the role and the ability to perform agency for the poor. In conclusion, this article recommends 4 steps to ensure that gender disaggregated data is really clearly designed and prepared before analysis and evaluation activities are carried out.

Authors: Ramadhan R A , Pigawati B 
Published: August 2019

Abstract
The rapid development of Semarang City has formed a metropolitan city pattern. The city of Semarang is as the core city, while the surrounding cities are as periphery. The high intensity of movement of the population from the periphery area to the core city during rush hour causes congestion at several regional liaison points. The implementation of the concept of Transit Oriented Development (TOD) is expected to solve these problems. The development of TOD-based areas in Kedungsepur has been demonstrated by the existence of commuter trains in early 2014 serving the Semarang City, Demak District, and Grobogan District, but has not provided maximum results. The purpose of this study was to examine the suitability of the application of TOD in 8 (eight) locations around the station passed by Kedungsepur commuter train by using descriptive quantitative approach and spatial analysis. The spatial analysis carried out was the analysis of variable density, and diversity. Design variable analysis was done based on observation. The results show that 8 (eight) station areas have the potential to form a TOD area. Based on the density variables, the Alasatua, Brumbung, Gubug, Karangjati, Sedadi and Ngrombo areas were in the high category, while Poncol and Tawang areas were in the low category. Based on diversity variables, only the Tawang and Alastua regions met the requirements, while other station areas did not meet the requirements. Based on the design variable, the feeder is available in all station areas. Connectivity between stations with feeders in 8 (eight) locations is also good enough but needs to be supported by adequate pedestrian infrastructure.

Published: August 2019

Abstract
The Chinatown of Semarang consists of many historical streets along with their heritage temples where a few informal social and physical urban developments occurred in those streets. This calls for a systematic urban redevelopment decision-making process. Using spatial data to demonstrate the current and future situations of street development, this paper aims at investigating the best scenario to develop Semarang Chinatown and also the advantages as well as the limitations of game theoretical models for the development of Semarang Chinatown. Therefore, we have developed game model based on Nash game theory, in which a certain action results in a certain payoff, for the case study. Our study demonstrates that game theory can provide key strategic decision of Chinatown development by showing the different payoffs of choosing main streets that are more urgent to be developed and selecting the equilibrium in which involved important stakeholders best interests. We also found limitations on using game theory in our case study especially regarding the assumption of preferred historical streets in the area.

Abstract
Diponegoro Prince Statue is one of the important icons in the campus area of Diponegoro University. Because the new statue is in the area of Widya Puraya. Therefore many people visit the statue. Diponegoro statue also experienced erosion by nature (wind, rain water, etc.). Therefore, it is necessary to preserve the Diponegoro statue so that it is not damaged and lost its existence by the times. In this research, two type of surveying instruments will be tested for their accuracy in the Diponegoro statue, namely non-metric cameras (NMC) and Unmanned Aerial Vehicle (UAV). The method used in this research is Close Range Photogrametry by comparing the results of the visualization of the model and testing the accuracy of the three-dimensional model with a comparison of the distance of the field measurements of the Total Station. From the results of visualization and accuracy of the three-dimensional model, it will be obtained which results are better between non-metric cameras and UAVs. The final results of this study indicate that UAV has a higher level of geometric accuracy compared to non-metric cameras. This is indicated by the results of the accuracy of the the UAV obtained a fairly good level of accuracy compared to the camera that is equal to 0.0162 ± 0.0133 meters for the statue of Prince Diponegoro. Whereas in non-metric cameras, the results of lower accuracy were 0.1615 ± 0.0593 meters in the statue of Prince Diponegoro. Based on the visualization of the three-dimensional model between the camera, UAV and NMC, it was found that UAV produced a better model compared to the three-dimensional model produced by NMC. With the results of the analysis in this study it is expected that the results of 3D modeling with cameras and UAVs can be used as an effort to preserve the Diponegoro statue.

Published: August 2019

Abstract
The GNSS Survey has been conducted for the deformation of Kaligarang Fault in 2016 and 2018. Active fault activity can be shown by the value of slip rate and locking depth. The magnitude of the slip rate cannot be measured directly, but the displacement on the surface of the earth data could be obtained from GNSS measurements. Then the slip rate could be calculated by inversion techniques from the displacement data form GNSS survey. We have done the slip rate modeling using the displacement data using the value of locking depth 5, 10, 15 and 15 km. But the position of the observation station point cannot converge to a single slip rate line at all locking depth values. Therefore this research has not been able to infer the optimal slip rate for Kaligarang fault.

AbstractIndonesian climate is characterized with abundant rainfall throughout the year. Differences the amount of rainfall are seen significantly in areas with monsoonal patterns in the event of extreme climates, both El-Nino and La-Nina. Rainfall pattern dynamic that occurs in Indonesia, even worldwide, is reflected by meteorological extrem events in several regions, i.e. extreme rainfall, season change, sea level rise, drought, and flood. Lombok Island is one small island in Indonesia with high levels of vulnerability to climate change. Regarding to the meteorological events occurred in Lombok, this research aims to identify spatiotemporal distribution of rainfall pattern changes in Lombok island during 1999-2014. TRMM (Tropical Rainfall Measurement Mission) data precipitation was used as the main data due to limitation of available precipitation data. Results show annual rainfall trend was decreased and most of monthly rainfall were increased. There was an anomaly during 2009-2010 when consecutive El Nino and La Nina hit Lombok. El Nino and La Nina strongly effected on rainfall amount in Lombok Island. Western part of Lombok island is wetter than the eastern part because the monsoon starts earlier in the west. The northern part has more intense rainfall due to the orographic factor.

Published: August 2019

Abstract
There are approximately 90% of the world natural rubber (NR) supplies are produced by the top 4 NR exporting countries, particularly Thailand, Indonesia, Malaysia and Vietnam. The export challenges and uncertainties of the NR latex in the ASEAN market are influenced by many factors. All these issues have driven the motivation of this study that aims to investigate the factors affecting the export of the NR latex, to analyse the relationship among the export price, production and exchange rate with the export, and to predict the export of the NR latex of the four countries. The data from 1999 to 2016 are utilized as the panel data analysis and granger homogeneously causality test for estimations. Estimation reveals that the independent variables, namely export price and production are exhibiting significant positively and the exchange rate shows a negative relationship with export. To conclude, Indonesia and Malaysia are estimated to have decreasing trends of NR latex export. Inversely, Thailand and Vietnam are predicted to exhibit increasing trends of NR latex export. The novelty of this study concerns effectively on the enhancement and stability of NR production in the ASEAN markets despite of the challenges arising from the global market integration.

Published: August 2019

Abstract
The thrust of the electric thruster for micro-nano satellites is very small, so it is very difficult to accurately measure the real-time variation of micro-thrust. In order to solve this problem, a real-time micro-thrust measurement system based on Barkhausen effect is proposed. Buckhausen effect is that under the action of external stress, the change of internal stress or strain of ferromagnetic material will cause the change of permeability, reluctance and flux of ferromagnetic material, which will result in Barkhausen noise under the external alternating magnetic field. Therefore, the change of stress or strain in ferromagnetic materials can be obtained by measuring Barkhausen noise. The micro-thrust measurement system based on Barkhausen effect proposed exactly in this paper transforms the change of thrust into the change of internal stress of the magnetoelastic element [1], which can realize real-time and high-precision measurement of instantaneous micro-thrust with the advantages of simple structure, easy operation and high reliability.

Local Information based Organization of Distributed Spacecraft Swarm Using Artificial Potential Field
Authors: Feng Wen , Wang Shuquan , Zhong Hongen 
Published: August 2019

Abstract
This paper investigates the problem of distributed organization of spacecraft swarm where each spacecraft is an independent agent that can interact with neighbouring members within a certain distance. According to the global objective of the organization, each agent makes decisions on its behaviour based on its own status and adjacent members within a certain distance. By a carefully designed strategy and under certain conditions, the swarm can accomplish the global objective. In the configuration reconstruction mission, only the expected global configuration is specified. The target position of each spacecraft is uncertain and not fixed. At the beginning of the reconstruction, every spacecraft can only determine the initial target point according to certain rules. It is possible to have conflicts of destination point selections since all spacecraft can only get local information. Each spacecraft constantly adjust their target point according to the local information in the process of accomplishing this task, until the group converges into the specified global configurations. In this paper, three different target allocation strategies are designed, so that each spacecraft can do continuous selection and optimization, and finally determine a non-conflict target matching to complete the formation reconstruction task. The artificial potential field method is utilized to control each spacecraft and complete the path planning, while ensuring that the spacecraft swarm to achieve collision avoidance and other requirements. In addition, the time and fuel consumption are compared. The numerical simulations show that these three strategies make obvious optimization effects.
