Abstract

IntisariPenentuan distribusi tipe awan berdasarkan diagram temperatur kecerahan (TBB) – perbedaan TBB dilakukan dengan menggunakan data citra satelit MTSAT IR1 dan IR2 pada bulan Januari dan Maret 2014 di 4 (empat) titik kajian di Provinsi Riau. Terdapat 6 (enam) tipe awan yang dikategorikan dalam diagram TBB-DT antara lain awan dingin dengan ketebalan optik besar (tipe awan Cumulonimbus/Cb), awan hangat dengan ketebalan optik besar (tipe awan Cumulus/Cu atau Stratocumulus/Sc), awan dingin dengan ketebalan optik kecil (tipe awan Cirrus/Ci yang cukup padat atau dense), awan hangat dengan ketebalan optik kecil (tipe awan Ci), serta awan tipe N yang merupakan tipe awan tipis di level rendah.  Dari seluruh data yang ada dalam pada bulan Januari 2014 dan Maret 2014, distribusi awan di daerah kajian didominasi oleh tipe awan Cirrus (Ci tipis, Ci tebal, dan Ci solid). Karakteristik wilayah Riau yang cenderung kering di bulan Januari maupun Maret 2014 mempengaruhi pertumbuhan awan di daerah tersebut dan kondisi cuaca didominasi oleh cuaca cerah. Dari perbandingan yang dilakukan antara hujan dengan tipe awan di 4 (empat) titik kajian, penentuan jenis awan penghasil hujan tidak dapat dilakukan hanya dengan mengambil data TRMM dan data TBB di suatu titik karena tidak menunjukkan adanya hubungan antara hujan dengan tipe awannya. Hujan yang jatuh di titik kajian bisa jadi tidak berasal dari awan yang berada tepat di atasnya karena faktor angin.Abstract  Determination of cloud type distribution based on the brightness temperature (TBB) – temperature differential image (DT) has been done using MTSAT IR1 and IR2 image data on January and March 2014 at 4 (four) point studies. There are 6 (six) cloud types categorized by the TBB-DT diagram: optically thick cold cloud (Cb type), optically thick warm cloud (Cu/Sc type), optically thin cold cloud (thin Ci type/dense Ci), and N-type which is low level thin clouds.  Based on all of the data from January and March 2014, cloud distribution on the field of study was dominated by Ci type clouds (thin Ci, thick Ci, and dense Ci). Dry characteristics of the area of Riau province influenced cloud development over the area and was dominated with fair weather. From the comparison between rain events and the cloud type, rain cloud determination cannot be done with only data point of TRMM rainfall data and MTSAT TBB data because it didn’t represent the relationship between rain events and it’s cloud type. Rain which fall on point study might not come from the clouds right on it due to the wind factor.

Abstract

IntisariKejadian El Nino yang berdampak pada sebagian besar wilayah Indonesia akan selalu berasosiasi dengan kekeringan akibat dari berkurangnya intensitas curah hujan. Lebih jauh akibat dari kekeringan tersebut telah menimbulkan meningkatnya titik api secara signifikan dibandingkan dengan tahun-tahun sebelumnya khususnya di wilayah Sumatera dan Kalimantan, dimana hal tersebut telah mengakibatkan terjadinya bencana asap pada tahun 2015. Tujuan utama penulisan karya tulis ini adalah untuk menganalisis kejadian El Nino pada tahun 2015 dan pengaruhnya terhadap peningkatan titik api di wilayah Sumatera dan Kalimantan baik dalam skala temporal maupun spasial. Dari hasil penelitian ini dapat diketahui bahwa berdasarkan parameter NINO 3.4 SST Indeks dan Southern Oscillation Index (SOI) pada tahun 2015 telah terjadi fenomana El Nino pada level kuat yang ditandai dengan adanya pelemahan sirkulasi walker sehingga pusat tekanan rendah perpindah dari Samudera Pasifik bagian Barat ke Samudera Pasifik bagian Timur, dimana hal ini telah menyebabkan adanya penurunan intensitas curah hujan (anomali negatif) disebagian besar wilayah Indonesia terutama pada bulan Juli hingga Oktober 2015 dan oleh karena itulah pada bulan Juli hingga Oktober 2015 tersebut terjadi peningkatan jumlah titik api yang sangat tajam di wilayah Indonesia dimana persebaran titik api tersebut sebagian besar terkonsentrasi di Provinsi Sumatera Selatan dan Kalimantan Tengah. AbstractEl Nino that impact most areas of Indonesia will always be associated in drought due to reduced rainfall intensity. Drought, in further, has resulted in increasing titik apis significantly compared to previous years, especially in the Sumatra and Kalimantan, that was creating smog disaster in 2015. The main objective of this research was to analyze the occurrence of El Nino in 2015 and its influence on increase of titik api in Sumatera and Kalimantan both in temporal and spatial scale. From this research it is known that based on the NINO 3.4 SST index and the Southern Oscillation Index (SOI) it is known there was a strong El Niño event occurred in 2015 showed there was a weakening Walker circulation so that the low pressure center moved from Western part of the Pacific Ocean to the Eastern Pacific Ocean, where this has led to a decrease rainfall intensity (negative anomaly) in most parts of Indonesia, especially from July to October 2015 and because of that from July to October 2015 there was very hight increasing number of titik apis in Indonesia where the spread of titik api the mostly concentrated in the province of South Sumatera and Central Kalimantan.

Abstract

IntisariBalai Besar Teknologi Modifikasi Cuaca (BB-TMC) BPPT bekerjasama dengan Badan Meteorologi Klimatologi dan Geofisika (BMKG) melakukan kegiatan Intensive Observation Period (IOP) selama puncak musim hujan pada tanggal 18 Januari - 16 Februari 2016 di wilayah Jabodetabek. Salah satu peralatan yang digunakan untuk observasi adalah Radiometer dan Radiosonde. Pada penelitian ini akan difokuskan bagaimana perbandingan hasil dari pengukuran Radiometer dan Radiosonde selama kegiatan IOP terutama untuk parameter temperatur dan kelembapan relatif. Hasil dari perbandingan pada profil atmosfer di lapisan tertentu terlihat adanya data yang mempunyai kecenderungan jauh dan tidak memiliki kedekatan nilai. Untuk pengukuran temperatur dengan radiometer jika dibandingkan dengan radiosonde, korelasi data semakin kecil di lapisan atas, sebaliknya jika untuk pengukuran kelembapan relatif, korelasi data di lapisan atas lebih tinggi daripada korelasi data di lapisan bawah. Sedangkan jika dibandingkan pada satu waktu antara radiometer dan radiosonde menunjukkan kecocokan untuk kedua data, meskipun kecocokan data kelembapan relatif lebih kecil dibandingkan data temperatur.  AbstractNational Laboratory for Weather Modification (BB-TMC) BPPT has colaborated with Meteorological Climatology and Geophysic Agency (BMKG) in conducting Intensive Observation Period (IOP) during the peak of rainy season in Jabodetabek area on January 18th- February 16th 2016. One of the tools used in the observation is Radiometer and Radiosonde. This study will focus on comparison result between Radiometer and Radiosonde measurement during IOP especially for temperature and relative humidity parameters. The result in a particular layer of profile atmosphere indicates that the data  tends to deviate away. The temperature difference measured using radiometer and radiosonde in the upper layer shows smaller value than that in the lower layer.  In contrast,  the correlation for relative humidity data in the upper layers is higher than in the lower layers. Meanwhile when compared at one time indicate a good match for both data, although the data matches of  the relative humidity are lower than the temperature data.

Abstract

Sang Hyang Dedari Dance in religious ceremonies is not only aimed vertically to Sang Hyang Widhi, but also bearing horizontal objectives, to sustain stable structure in Bali society. This study aims to describe the layers of the society, so it can be understood critically what is meant by women of Bali—that the multicultural discourse, indigenous women celebrate the customs and traditions as an act against the root of patriarchy. Yet there is always a need to reexamine the roots. Root is not absolute, and a single tone, but rhizomes that question the hegemony of the hierarchy in winning gender equality against patriarchal subordination.

Abstract

Introduction: Dengue NS1 Antigen (NS1 Ag) detection or quantification has become a specific diagnostic tool for dengue virus infection, but has variable sensitivity. Previous research reported NS1 Ag level can be detected up to the 7th–10th day of fever, others stated the sensitivity was decreased after four days of fever. We performed this research to analyze the NS1 Ag profile and its relationship with the day of illness. Methods: This study was a prospective cohort study on 39 children hospitalized at Dr. Soetomo Hospital Surabaya since November 2009 to May 2010. Inclusion criteria were acute fever less than 72 hours, bleeding tendency denoted at least by positive tourniquet test, age between 1–14 years, and confirmed by positive dengue IgM/IgG on the 5th day of fever. We performed daily quantitative dengue NS1 Ag tests until defervescence day, and its relationship with the day of illness were analyzed. Results: NS1 Ag was positive in 19/39 samples. Secondary infection occurred in 14/19 of Dengue Fever and 17/20 of Dengue Hemorrhagic Fever cases. Positivity of NS1Ag was higher in primary (6/8 cases) than secondary infection (12/31 cases). Mean level of NS1 Ag was highest on the 2nd day, decreased afterwards and undetected on the 5th day of fever. There was significant relationship between NS1 Ag positivity (P=0.037, rs=-0.9) and level (P<0.001, rs=-1) with the day of illness. Discussions: Dengue NS1 Ag positivity and level were highest during the acute phase of fever and decreased afterwards.

Abstract

Global climate in 2015 was greatly affected by the occurrence of El Niño Southern Oscillation. The appearance of El Niño has been widely predicted since 2015 by various research institutions in the world that work in the field of Meteorology and Climatology. In early September 2015, experts from World Meteorological Organization (WMO) stated that the El Niño occurred in 2015 will be one of the strongest El Niño in history. Based on a calculation, the value of Sea Surface Temperature (SST) in the waters of the East-Central Pacific Ocean tends to be warmer more than 2 degrees Celsius from the average value. El Niño that impact most areas of Indonesia will always be associated in drought due to reduced rainfall intensity. Drought, in further, has resulted in increasing hotspots significantly compared to previous years, especially in the Sumatera and Kalimantan region of Indonesia, creating smog disaster in 2015. The main objective of this research was to analyze the occurrence of El Niño in 2015 and its influence on increase of hotspot in Sumatera and Kalimantan both in temporal and spatial scale. This research use the integration of Meteorological-Climatological and Geographic Information Systems Science based, Nino -3.4, Sea Surface Temperature (SST) and Wind Gradient for El Niño events analysis, also MODIS Satellite high accuracy data for Hotspot distribution analysis. It can be seen that there was a most powerful El Niño phenomenon compared the history that the peak event in November 2015 with value 2.95 of Nino -3.4. Gradient Wind from June to December 2015 has shown the movement of water vapor Pacific Ocean tendency towards the East, resulting decrease of rainfall intensity in the Pacific Ocean in the Central and Western region including Indonesia. Based on the analysis both spatial and temporal, it's shown that South Sumatera and Central Kalimantan are regions with highest increase in total hotspot, the total hotspot increased by 363% for South Sumatera and by 231% for Central Kalimantan.
