Investigating the Impact of Carbon Tax to Power Generation in Java-Bali System by Applying Optimization Technique
Java-Bali power system dominates the national installed capacity and will contribute to about 76% of the national CO2 emissions from the electricity sector in the future. Thus, minimizing CO2 emission from the Java-Bali system can help Indonesia to reduce the national CO2 emissions level. We apply optimization approach to investigate this problem by including carbon tax into the cost function. We analyzed data based on electricity generating system in 2008. In general the optimization showed that diesel and gas turbine is not needed in the power plant system. Further, the simulation showed that if Indonesia adopted carbon tax by US 50/tCO2. There are some weaknesses from this study such as not use strong assumption for availability factor and generating costs. This study proposed that government needs to optimize utilization of combine cycle power plan to offset steam power and implement carbon tax above US$ 50/ ton CO2, to reduce CO2 emissions significantly.Power generation, Carbon tax, Optimization

Towards greater health coverage in Indonesia:An evaluation of National Health Insurance (JKN) reform and healthcare use and equity
Following the implementation of National Health Insurance (JKN), the ongoing efforts to improve health coverage in Indonesia face several challenges that need to be explored. These challenges include consolidating existing health insurance schemes and introducing self-enrolled schemes to enhance healthcare utilization effectively. Moreover, socioeconomic and geographic disparities persist, hindering equal access to healthcare benefits across different groups and regions. Another critical aspect is assessing the effectiveness of BPJS Kesehatan's performance-based capitation in addressing health quality concerns, particularly in primary care settings. Additionally, understanding the impact of natural disasters, such as the 2015 forest fires, on healthcare utilization is crucial. In this doctoral dissertation, we explore these challenges and their implications. Firstly, we examine the relationship between increasing coverage share and healthcare utilization at the district level, revealing a positive correlation, especially in hospital care. However, concerns about adverse selection with self-enrolled schemes pose financial sustainability risks for JKN. Secondly, we assess healthcare funding distribution under JKN, highlighting significant benefit incidence for wealthier groups and regional variation in hospital unit costs. Thirdly, we analyze the implementation of performance-based financing through the KBK scheme for community health centers (puskesmas). Despite high expectations of the results, our findings indicate limited success in promoting primary care utilization (increasing but not met the target). Lastly, we investigate the impact of the 2015 forest fires on healthcare utilization, focusing on specific respiratory conditions. While limited effects were observed for older individuals, positive impacts were noted for young children seeking care in urban primary healthcare facilities.<br/

SEMI-AUTOMATIC SHIP DETECTION USING PI-SAR-L2 DATA BASED ON RAPID FEATURE DETECTION APPROACH
Synthetic Aperture Radar (SAR) satellite an active sensor offering unique high spatial resolution regardless of weather conditions can operate both day and night time with wide area coverage. Therefore, SAR satellite can be used for monitoring ship on sea surface. This study showed on an alternative method for ship detection of SAR data using Pi-SAR-L2 (L-band, JAXA-Airborne SAR) data. The ship detection method is this study was consisted of eight main stages. After the Pi-SAR data was registered and speckle was filtered, then the land was masked using SRTM-DEM (Shuttle Radar Topography Mission-Digital Elevation Model) data since most ship detectors produced false detections when it applied to land areas. A ship sample image was then selected (cropped). The next step was to detect some unique keypoints of ship sample image using Speeded Up Robust Features (SURF) detector. The maximum distance (‘MaxDist’) of keypoints was also calculated. The same detector was then applied to whole Pi-SAR imagery to detect all possible keypoints. Then, for each detected keypoint, we calculated distance to other keypoint (‘Dist’). If ‘Dist’ was smaller than ‘MaxDist’, then we marked these two (or more) keypoints as neighboring keypoints. If the number of neighbor keypoints was equal or greater than two, finally we marked these keypoints as ‘Detected Ship’ (draw rectangle and show its geographic position). Results showed that our method can detect successfully 32 ‘possible ships’ from Pi-SAR-L2 data acquired on the area of North Sulawesi, Indonesia (August 8, 2012)

The Impact of Jamkesmas on Healthcare Utilization in Eastern Regions of Indonesia: a Propensity Score Matching Method
Underutilization of health care for the poor is one critical problem in Indonesia. Out of pocket share is dominant on overall health financing. Therefore, it is plausible that low demand of modern healthcare services mainly relates to financial aspect. In 2008, the government of Indonesia has introduced health insurance schemes for the poor to help them overcome the problem of medical costs barrier called Jamkesmas (Social Health Insurance). This paper examines the impact evaluation of Jamkesmas to health care utilization in Eastern Indonesia. Data are drawn from Indonesia Family Life Survey East (IFLS-East) that held in 2012. This data only covers the eastern regions of Indonesia that widely known has relatively lower performance in development and infrastructure. Moreover, this study employs Propensity Score Matching (PSM) approach to analyse the data. The results show that average treatment effect for treated group are positive for outpatient utilization. In addition, availability of the healthcare facility variables, travelling time and distance to district capital are factors that determine Jamkemas coverage in Eastern Indonesia
