This study is about radioprotection in the case of the Fukushima-Daiichi Nuclear Power Plant accident that happened in 2011. It focusses on the retrieval of the corium in the core of the reactor. OAKRIDGE created a project that also responds to the international call of IRID (International Research Institute for Nuclear Decommissioning). The concept is based on the rapid pneumatic transfer of closed capsules that contain debris of corium. This project is now focused on the utilization of developed computing software that can be experimented on the dose rate of corium based on previous works. This software is called PANTHERE. With PANTHERE, we can propose multiple methods of online attenuation calculation with the dose rate (DED H*(10) in mSv/h, KERMA in the air in mGy/h,flux-dose in particles/cm2/s or energy fluencies in MeV/cm2/s). With PANTHERE, we modelized the corium and ran a corium retrieval simulation based on a point of observation to calculate the dose rate of corium inside the capsule inside the BWR Fukushima reactor. After that, we also modelized the trajectory of the capsule from when it is inside the RPV (Reactor Pressure Vessel) until when it is inside the storage system in SFP (Spent Fuel Pool). The highest dose rate given by the calculation was $3.24times 10^{-3}$ rnSv/h.

Stunting is one of the most prevalent forms of child malnutrition with estimated 22.2% children in Indonesia suffered from it. Children with stunting have shorter body height compared with normal children and usually associated with various effects, including cognition, memory, and locomotor skills. As walking is one of the locomotor skills, it is important to evaluating stunting children by their style of walk which refers to a gait. In this present study, twelve normal children and six stunting children with 2 years of age were assessed during gait trials at self-selected speed. Fifty-four gait cycles from three gait trials for all children were selected. Joint angles and angular velocity were computed using 2D video analysis. Statistical analysis was performed to find significant difference on the kinematic parameters between two groups. Based on the current results, we concluded stunting children have similar kinematic gait characteristics with normal children. Future studies should involve kinetic and spatio-temporal parameters to understand clearly the gait character

The 2004 tsunami destroyed most of the built-up areas in the city of Banda Aceh, Indonesia. The physical development recoveries were immediately taken place to restore urban function. This study aims to identify spatio-temporal patterns of built-up expansion in the city of Banda Aceh during the recovery (2005–2009) and post-recovery period (2009–2019). Urban land cover was classified from Landsat imagery using the supervised classification method with maximum likelihood. The results indicate that the built-up area has increased from 1426 ha in 2005 to 3321 ha in 2019. The intensity of growth in the initial period was high, while the intensity in the following period has decreased significantly. Urban recovery had contributed greatly to the built-up expansion in a relatively short period of time. This study also proved the difference in the direction of expansion at the micro-scale (sub-district level) in the two periods.

Airborne gravity technique is more effective for geodetic and geophysical purposes especially over large and varied areas. However, the use of airborne gravity of Sulawesi Island has not been optimal, including the use of gravity disturbance data components compared to gravity anomaly data that is more commonly used. In this research, mapping of gravity disturbance was done based on airborne gravity data and subsequently was applied for interpretation of the geodynamics of Sulawesi Island region. Gravity disturbance value was obtained through the conversion of free-air anomaly. The results showed that the gravity disturbance of Sulawesi Island ranged from -206.10 to 352.58 mGal with a pattern similar to the free-air anomaly and two global models (EGM2008 and EIGEN-6C4). The difference with EGM2008 and EIGEN-6C4 was an average of -3.77 and -3.43 mGal with a standard deviation of ±26.59 and ±26.21 mGal. The large difference is probably due to a data gap and topographic area of the mountains. Map of gravity disturbance can also be used for the initial interpretation of active faults such as Palu Koro and Matano which showed a significant color deviation from the representation of significant differences in subsurface geological structures.

Sustainable timber production and global climate change mitigation become important issues in tropical rainforests management around the world, including Indonesia. In this case, the existence of a tropical rainforest is not only directed to stabilize wood supply but also reduce carbon emission in the atmosphere. Estimation of timber production and carbon storage in a tropical rainforest using field inventory requires long-time consuming and high cost. Therefore, an alternative method is proposed to support a more efficient forestry inventory. This study aims to evaluate the potential of remote sensing for facilitating the implementation of forest inventory in a tropical rainforest area. A hybrid approach of remote sensing using two different images resolution, i.e. medium and high was developed to estimate timber production and carbon storage with three predictor variables, namely canopy closure (C), crown diameter (D), and tree density (N). Then, a computational model was constructed from database management systems using a case-based reasoning approach. Results demonstrated that using remote sensing for tropical rainforest inventory provided a good accuracy to estimate timber production and carbon storage with Normalized Root Mean Square Error (NRMSE) around 18%. This study recorded the mean timber production in the study area was 79.91 m3ha -1 with average carbon storage by approximately 14.33 Mg ha -1. Reviewed from these findings, there was an opportunity to use a hybrid approach of remote sensing for supporting forest inventory in the tropical rainforest.

The use of unbalanced land function with the ability and availability of land can increase land degradation from one of the erosion. This case in the Mongo Watershed which has a high level of soil criticism based on the data management plan of the Bogowonto 2018. This erosion can lead to decreased soil quality and loss of fertile soil, resulting in a direct impact on crop productivity. It can be minimized by doing erosion forecasts so that it can determine the appropriate mitigation. Estimate erosion by utilizing remote sensing technology and Geographic Information Systems (GIS) because the updates can be done quickly, covering a large and hard-to-reach area, and cheaper costs, so that it can be more effective and efficient. The modeling method used is the MUSLE method (Modified Universal Soil Equation). Modeling uses remote sensing data such as Sentinel 2A imagery, DEM ALOS PALSAR, and TRMM data. The use of TRMM data has improved the model through the addition of more accurate rainfall spatial information. The results of the erosion estimation in Mongo Watershed are dominated by very light and the overall erosion rate has a value from 0 to 221.483 tons/ha/yr.

This paper focuses on the review of the recent advancement and development of indoor localization focusing on device-free indoor localization (DFIL). DFIL offers more flexibility for the user or object point-of-view. The basic idea is to free the object from the device attached for localization process. The most popular technologies for DFIL are based on wireless technology. However, if we discuss the low-cost system, we have to discuss the fusion or hybrid of many sensors output data to increase accuracy. Some of the accessible technology used for these low-cost systems are wireless-based, i.e., Wi-Fi, ZigBee, radio frequency identification (RFID) and an optical-based, visible light communication (VLC). Wireless-based probably the most used in the low-cost and simple configuration of an indoor localization since the parameter used can be directly obtained from its device. The most used parameter in the wireless-based system is received signal strength indicator (RSSI), which merely the derivation of power by the distance. By this parameter, the technique such as trilateration, min-max, and RSSI database can be used as the location. In the DFIL, RSSI can be applied as the Wi-Fi -based radio map from two or more links and applying an algorithm such as the Bayes Inference, resulting in the accuracy of object tracking up to 86%. On the other hand, ZigBee applies to mesh network and need more nodes to gather more information for higher accuracy results. The RFID has advantages in no-contact, and a good accuracy even in non-line-of-sight (LoS) condition. Optical-based VLC can provide high accuracy but dependent on the light noise and shadow effect in the object.

Krisnawan","doi":"10.1109/ICST50505.2020.9732779","DOIUrl":"https://doi.org/10.1109/ICST50505.2020.9732779","url":null,"abstract":"This paper focuses on the review of the recent advancement and development of indoor localization focusing on device-free indoor localization (DFIL). DFIL offers more flexibility for the user or object point-of-view. The basic idea is to free the object from the device attached for localization process. The most popular technologies for DFIL are based on wireless technology. However, if we discuss the low-cost system, we have to discuss the fusion or hybrid of many sensors output data to increase accuracy. Some of the accessible technology used for these low-cost systems are wireless-based, i.e., Wi-Fi, ZigBee, radio frequency identification (RFID) and an optical-based, visible light communication (VLC). Wireless-based probably the most used in the low-cost and simple configuration of an indoor localization since the parameter used can be directly obtained from its device. The most used parameter in the wireless-based system is received signal strength indicator (RSSI), which merely the derivation of power by the distance. By this parameter, the technique such as trilateration, min-max, and RSSI database can be used as the location. In the DFIL, RSSI can be applied as the Wi-Fi -based radio map from two or more links and applying an algorithm such as the Bayes Inference, resulting in the accuracy of object tracking up to 86%. On the other hand, ZigBee applies to mesh network and need more nodes to gather more information for higher accuracy results. The RFID has advantages in no-contact, and a good accuracy even in non-line-of-sight (LoS) condition. Optical-based VLC can provide high accuracy but dependent on the light noise and shadow effect in the object. From these benefits and disadvantages of some low-cost systems, we can make the best of them by fusing the sensor or developing the hybrid system.","PeriodicalId":125807,"journal":{"name":"2020 6th International Conference on Science and Technology (ICST)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130882149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
