Published: May 2019

Abstract
Regional development usually start with identifying regional potencys. Defining a local potencies such as primary agricultural commodities is a basic capital in developing regional economic. The concept of determination is pointed by Barlowe (1986), which include bio-physically suitable, economically feasible and institutionally acceptable. The approach (analysis) used in this research is Geographic Information System (GIS), commodity base analysis (LQ), differential shift (SSA), gross margin (GM), distance to market location, process hierarchy analysis (AHP), and multicriteria land index. This research is located in transmigration area of Rawa Pitu Sub District, Tulang Bawang Regency, Indonesia. This research aims to identify basic commodities for each village. The results shows that several land parameters which include land suitability and accessibility, comodity parameters which include LQ and SSA as well as economic parameters which include GM can be used to determine primary commodity in a region. They composed what we call as multicriteria land index. There were some basic commodities identified using such index, which include paddy, maize, rubber, and oil-palm. Paddy is a primary comodities in certain villages. Whereas maize and oil palm is a primary comodities in another villages. Rubber is not a primary comodities in any village.

Abstract
Drought is a natural hazard indicated by the decreasing of rainfall and water storage in the region and impacting agricultural sector. Recently, satellites data are widely used for calculating the drought indices. Since 2010, Bogor Agricultural University (IPB) and the National Institute of Aeronautics and Space of Indonesia (LAPAN) had launched satellite, called “LISAT” LAPAN-IPB Satellite. The objectives of the research are (1) to compare NDVI values from two different satellites –LISAT and Landsat (2) to analyzed the relationship between climate variability using spatial rainfall data with NDVI values over Pakisjaya District in specific time of study, (3) to validate NDVI derived from LISAT data with field observation. The study area will focus in Pakisjaya District, Karawang, West Java, one of Java agricultural production center. The biggest potentials in Pakisjaya district are agriculture, plantations and fish ponds. Therefore, the identification of drought in Cirebon is expected to be used as an early warning of drought and mitigation measures to reduce the impact of drought on agricultural sustainability. The results showed drought occurrence in 2017 was caused by the shifting of wet season. Wet season that should occurred in January, but from rainfall estimation using CMORPHs, wet season was delayed to April. It is associated with NDVI data derived from LISAT and Landsat 8 results. Highest NDVI was found in April, and the lowest NDVI was found in January. Nevertheless, NDVI value derived from LISAT were low than literature, but generally from the pattern, it can differentiate well different land used observed. Overall, this study can be used as drought mitigation, particularly for the agricultural farmers, so that they can arrange the suitable planting time.
Influence of the Indian Ocean Dipole (IOD) on Convectively Coupled Kelvin and Mixed Rossby-Gravity Waves

Published: May 2019

Abstract
Indian Ocean Dipole (IOD) is a mode of natural climate variability that arises from a zonal-dipole structure in interannual variations of the tropical Indian Ocean. Understanding the influence of IOD on atmospheric circulation is important in order to improve weather forecasts and climate predictions in the Tropics and the extratropics on time scales beyond a few days. This study investigates the role of IOD on convectively coupled equatorial wave (CCEW) activity, including Kelvin and MRG waves and examines the potential links between them. The results show that positive IOD event leads to enhance Kelvin wave and MRG wave activities over the eastern Africa and southern Indian Ocean. On the other hand, it suppresses Kelvin and MRG wave activities over the eastern Indian Ocean and the Maritime continent. It is also shown that IOD’s influence on Kelvin and MRG waves activity is non-dependent to ENSO activity. These results highlight the importance of IOD in generating Kelvin and MRG waves in the tropics.
Unprecedented Quasi-Biennial Oscillation (QBO) disruption in 2015-2016: Implications for tropical waves and ozone
Authors: Kusuma Lintang , Lubis Sandro W. , Setiawan Sonni 
Published: May 2019

Abstract
During the Northern Hemisphere (NH) winter of 2015/16, quasi-biennial oscillation (QBO) exhibited a significant disruption that was unprecedented in the observational record. It was characterized by an upward displacement of the westerly wind anomalies. Since traveling wave activity induces the QBO and in turn affects the ozone distribution, it is worth understanding how this anomalous change affects tropical waves activity (including Kelvin and MRG waves) and ozone. This study used assimilated ozone product from the Modern-Era Retrospective Analysis version 2 (MERRA2). The results showed that Kelvin and MRG wave activities are appreciably strong during this period. The strengthening of Kelvin wave activity is consistent with a persistent westerly background flow, favoring upward propagation of Kelvin waves into the stratosphere. On the other hand, the significant strengthening of MRG wave activity may be associated with enhanced equatorward propagation of extratropical Rossby waves due to strong El-Nino event. Furthermore, the results also indicated that the anomalous change in the QBO leads to increasing temperature and ozone concentration in the tropical lower stratosphere. Based on ozone budget analysis, we showed that the increase in total ozone tendency is largely attributable to the increase in dynamical ozone transport, being consistent with the QBO-induced residual circulation between the mid and low latitude, in the lower stratosphere.

Abstract
Peat swamp forest is one of the wetland tropical rainforest ecosystems widespread in Indonesia. This study aimed to analyze plant species diversity of tree stage in difference logged-over peat swamp forests at PT. Diamond Raya Timber, Riau Province. This study site was divided into three different locations, newly logged-over peat forest swamp forest (NLPSF), three years logged-over peat swamp forest (3LPSF) and four years logged-over peat swamp forest (4LPSF). Primary species of tree stage in the study site were grouped into three parts, i.e., firstly, Dipterocarpaceae family mainly consists of meranti bunga (Shorea teysmanniana) and meranti batu (S. uliginosa), secondly, non-Dipterocarpaceae included balam (Palaquium hexandrum), milas (Parastemon urophyllus), macang (Mangifera havilandii), punak (Tetramerista glabra), jambu (Eugenia sp), pisang-pisang (Mezzetia parviflora), and arang-arang (Gynotroches axillaries), and thirdly, particular species of ramin (Gonystylus bancanus). The pattern of species grouping for tree level was more centered in the NLPSF compared to other sites. On the other hand, species diversity in tree level found more diverse in 4LPSF, suggested the various ecological parameters. Cluster analysis showed the occurrence of species relationship in the sites based on diameter and importance values indicated the presence of species similarity and habitat preference.

Abstract
The dynamic changes of aquatic ecosystem have an important role in order to maintain the sustainability of peat land ecosystem. The aquatic ecosystem is the main supply of freshwater in the Barito basin region, contribute to the water quality for consumption and production, habitat for aquaculture. Therefore, the spatial modelling of inundation changes is a pre-requisite for future peat land management. This study employed GIS and Remote Sensing techniques to monitored land cover/land use changes for observed inundation in Barito basin, South Borneo, Indonesia using multispectral satellite data obtained from Landsat at 1994, 1996, 2013 and 2015 respectively. The Barito peat basin areas, based on object dominance, were classified into five cover classes/dry land use compilation namely swamp bushes, open areas, transportation, galam vegetation (Melaleuca sp) and water bodies. The truth value was 88.48% for Overall Accuracy and 0.8 for Kappa which belonged to the substantial category. Land cover/land use resulting from spatial analysis showed a significant increase in water bodies totally 24% from 14% in 1994. Inundations that were close to the Barito river flow had a typical permanent compared to those that were far from the river. Regarding inundations throughout the season contributed to the management and development of the socio-economic area.

Abstract
The coral bleaching event (CBE) which trigerred by increase in sea temperatures of 1-2˚C during El-Nino can make corals stressful or potentially dead. Many CBE research are conducted using sea temperature data measured through infrared thermal (TIR) satellite sensor. However, very few study use optical remote sensing data. This study aim to analyze the potential of optical Sentinel-2 (S-2) satellite data for monitoring during (Jun. 2016) and after (Jun. 2018) CBE in small islands of marine protected areas (TWP) of Pieh. A series image analysis procedure was conducted, i.e. simple DOS atmospheric correction; normalizating digital numbers (DN) of Blue, Green and Red bands of subject images during and after CBE to the reference image (before CBE. Dec. 2015) using “pseudo invariant feature (PIF)” approach; subtracting the DN of each bands of images during and after CBE to the reference image, and generating color composite of natural color with a contrast stretch. Result showed that this procedure can detected clearly the CBE. There was an average decreasing bleaching trend of 1.63 ha (15.8%), which indicated that some corals have recovered from thermal stress inside the TWP of Pieh. However, islands outside the TWP of Pieh, showed an increasing trend by an average of 0.50 ha (21.2%). The predation corals by the crown of thorn seastar, Acanthaster planci, whose population exploded after CBE was the main reason why CBE still detected both inside and outside the TWP of Pieh. This study shows the ability and potency of optical remote sensing data of S-2 satellite to monitor CBE, but need a lot of validation from many other sites. This result is very useful for supporting project such as COREMAP CTI.

Abstract
During the Java-Makassar-Flores (JMF) Cruise in August 2015 onboard the RV GEOMARIN 3, about 56 hydrographic CTD profiles have been acquired in the JMF confluence region of Makassar Indonesian Throughflow (ITF) and seasonal Java-Flores Current, where three intensive 24-h CTD “yoyo” measurement were carried out in Dewakang sill, Selayar slope and Kangean slope. The aim of this paper is to estimates the turbulent mixing value using Thorpe analysis, particularly in the Selayar slope - southern Makassar Strait. It is found that below surface potential density of 24.25 σθ stratification of water masses is dominated by Makassar ITF with salty (34.6 psu) North Pacific thermocline water (NPSW) and less salty (34.42 psu) North Pacific lower-thermocline water (NPIW). However, above 24.25 σθ upper NPSW is drastically dominated by much fresher water (34.17 psu) from Java Sea, where inter-leavings of salinity profiles are obviously seen between surface density of 22.0 σθ and 23.50 σθ. Estimation of turbulent vertical eddy diffusivity in this upper-thermocline are found strong with the order of 10−3 m2/s. It is suggested that energetic internal tidal waves may contribute significantly to the vertical mixing in this complex topographic region.
Design and analysis of multibeam communication satellite links operated at Ka Band Frequency in Indonesia
Authors: Qonita Aulia Haque , Muhtadin Nurul 
Published: May 2019

Abstract
In this paper, we design the link budget of communication satellite. This communication satellite is designed for Ka-Band Frequency for broadband communication in Non-Geostationary Orbit (NGSO) with altitude of 1200 km. The ability of this communication satellite depends on the strength of the signal and the amount of thermal noise. Ka-Band has wider bandwidth and higher data capacity but the drawback of this frequency is it is susceptible to rain attenuation in which Indonesia is an equatorial area that has high rainfall rate, so that the design of communication satellite in Ka-Band needs more consideration to determine satellite system parameter to keep the signal strength great. Indonesia is a wide archipelago country and satellite link design requires beam that can cover all Indonesia with great signal strength and multibeam antenna technology is one of solutions to overcome it. In this research, design and analysis of communication satellite is done using multibeam antenna. The main challenge of the design is to generate the link budget’s result to meet determined parameter. Iterative calculation in design must be used to find an effective link margin and bit rate of this communication satellite. The main result of this research is multi beam satellite provide better performance than single beam satellite in Ka band frequency. The use of BPSK modulation in multi beam satellite shows better performance than other modulation types.

Published: May 2019

Abstract
Telecommand is a command sent to control a remote system or systems not directly connected to the place from which the telecommand is sent. In the telecommand process, there is a data processing process so that the command data that will be sent can be read / translated and processed accurately by the satellite. The Consultative Committee for Space Data Systems (CCSDS) provides recommendations for the telecommand process. CCSDS uses layering model to describe telecommand process, one of them is coding layer. This paper will talk about the simulation of coding layer of telecommand process based on CCSDS recommendation. The simulation involves randomization process, BCH encoding, and BCH decoding using MATLAB software. The result of this simulation shows encoding and decoding process successfully managed and produced data format which complies with CCSDS recommendation.

Published: May 2019

Abstract

Objectives
Analysis of platelet functional responses to stimuli is presently quite limited with respect to measurement of dense granule secretion. We sought to develop a nonradioactive assay of stimulated serotonin release using liquid chromatography tandem mass spectrometry (LC-MS/MS).

Methods
Citrated whole blood (200 μL) was incubated with deuterated serotonin (d45-HT). Following uptake by platelets, blood was diluted 10-fold and aliquots were incubated with platelet stimuli. Following stimulation, blood was further diluted, centrifuged, and supernatant was assayed for released d45-HT by micro-LC–MS/MS.

Results
This study demonstrated a broad linear range of 50 to 2,000 pg/mL d45-HT, with a total precision of less than 15.0% coefficient of variation at all quality control levels and a limit of quantitation of 50 pg/mL.

Conclusions
Quantification of d45-HT by micro-LC–MS/MS assay offers a highly sensitive, nonradioactive methodology for quantitating platelet serotonin uptake and dense granule secretion, requiring only small volumes of patient blood.
Family History–Wide Association Study to Identify Clinical and Environmental Risk Factors for Common Chronic Diseases

Published: May 2019

AbstractFamily history is a strong risk factor for many common chronic diseases and summarizes shared environmental and genetic risk, but how this increased risk is mediated is unknown. We developed a “family history–wide association study” (FamWAS) to systematically and comprehensively test clinical and environmental quantitative traits (CEQTs) for their association with family history of disease. We implemented our method on 457 CEQTs for association with family history of diabetes, asthma, and coronary heart disease (CHD) in 42,940 adults spanning 8 waves of the 1999–2014 US National Health and Nutrition Examination Survey. We conducted pooled analyses of the 8 survey waves and analyzed trait associations using survey-weighted logistic regression. We identified 172 (37.6% of total), 32 (7.0%), and 78 (17.1%) CEQTs associated with family history of diabetes, asthma, and CHD, respectively, in subcohorts of individuals without the respective disease. Twenty associated CEQTs were shared across family history of diabetes, asthma, and CHD, far more than expected by chance. FamWAS can examine traits not previously studied in association with family history and uncover trait overlap, highlighting a putative shared mechanism by which family history influences disease risk.
