Abstract

Dampak pemanasan pulau perkotaan (urban heat island (UHI)) pada curah hujan ekstrem dan aerosol telah dikaji dalam penelitian ini menggunakan data curah hujan harian dan konsentrasi aerosol bulanan (NO2, SO2, dan SPM) di stasiun Badan Meteorologi Klimatologi dan Geofisika (BMKG) pada megapolitanJakarta dan wilayah pegunungan Bogor dan Citeko dari 1986-2012. Analisis harmonik dilakukan untuk menghilangkan pengaruh musiman pada hasil tren data curah hujan dan selanjutnya signifikansi tren tersebut diuji dengan metoda statistik Mann-Kendall. Hasil penelitian menunjukkan dampak pemanasanpulau perkotaan (UHI) telah terjadi secara nyata dengan tren peningkatan curah hujan ekstrem dari indikator total hari hujan 40, 50 dan 100 mm/tahun dan konsentrasi aerosol di wilayah megapolitan Jakarta dan sekitarnya dengan laju tren masing-masing sebesar 0.17 hari/tahun, 0.17 hari/tahun, dan 0.04 hari/tahun, dan 3.7e-004 ppm/tahun (NO2) dan 0.148 ppm/tahun (SO2). Namun sebaliknya terjadi tren penurunan di wilayah pegunungan Bogor dan Citeko. Hasil penelitian ini menunjukkan ada indikasi peningkatan UHI menyebabkan kenaikan konsentrasi aerosol di megapolitan Jakarta dan kondisi ini menjadi trigger peningkatan curah hujan ekstrem yang berdampak pada intensitas banjir yang semakin meningkat sejak tahun 1986.Kata kunci: Pemanasan pulau perkotaan, curah hujan ekstrem, aerosol, tren

Abstract

A-14-year (1979-1993) image satellites of Solar Radiation, NOAA and SeaSurface Height Anomaly of TOPEX/POSEIDON and ERS-2 have been used to study a reducing solar radiation received by the Earth (global dimming) and to predict local weather anomaly for the future climate prediction in the Indonesian region. The result shows that a dimming of solar radiation is of 16.6% during 14-year observation. It is higher than the mean increasing of global dimming of 2 - 3% for every decade. This explicitly indicates that the air pollution in the form of aerosols from industrial sectors has large contributions to this this dimming process. At the other side, there is a trend of dominant warm water in the southern Jawa-Bali that affect on the increasing of rainfall intensity in the Indonesian region. We predict that flood and a longer dark during the day time, and more variative local weather change will be more frequently happen in the Indonesian region in the futu

Abstract

There is an inter-annual phenomenon in the Indian Ocean that occurs because of the interaction between atmosphere and ocean are known Indian Ocean Dipole (IOD). IOD is a bipolar structure that characterized by the difference of sea surface temperature to normal. The objectives of this study is to know the characteristic of physical oceanography in the eastern part of Indian Ocean during the formation phase, maturation phase and decay phases of positive IOD. The second objective was to determine the comparative characteristic of physical oceanography in the eastern Indian Ocean between the positive IOD in different years. The strengthening of the South Equatorial Current in transitional seasons I (March-May) followed by early cooling of the SST which is indicated by the formation phase of IOD. At the Southeast monsoon (June to August) and the beginning of the season transition II, there is a visible presence of upwelling in the south of Java, which is then further extends to the peak in September (maturation phase) and begin to disappear in October followed by warming of the SST on the East of Indian Ocean in November (decay phase).Keywords: Indian Ocean Dipole, upwelling, Empirical Orthogonal Function (EOF) analysis, Eastern Indian Ocean

Abstract

The heat island (HI) effect in metropolitan Jakarta was studied using air temperature measurements at 9 meteorological stations in Jakarta, Tanjung Priok, Serang, Halim, Cengkareng, Pondok Betung, Curug, Bogor, Citeko during 1986-2008 and Serpong during 2008-2011 and 2013; land use for forest, industry, water, settlement, open/cleared land in 1997, 2004, 2009, 2012; and total number of industries and total number of vehicles during 1986-2011. Harmonic analysis was used to remove the seasonal component from the temperature time series data, which was filtered with the 30-day moving average technique to capture trends whose significance was tested with the Mann-Kendall method. The results show that industry was a major factor in land use change over Jakarta with an increasing growth/year of 502 ha (9.76%) concentrated in the eastern part of Jakarta from 1997 to 2012. Industry had a spatial cover change similar to deforestation and open/cleared land expansion, especially in Jakarta from 2009 to 2012: 38.8%/year (industry), 8.3%/year(deforestation), and 13.8%/year (open/cleared land). The HI effect increased the temperature trend rate/year in Jakarta, Tanjung Priok, Serang, Halim, Pondok Betung, Cengkareng, Curug, and Bogor about 0.051°C, 0.021°C, 0.018°C, 0.012°C, 0.006°C, 0.006°C, 0.005°C, and 0.004°C from 1986 to 2008, respectively, equivalent to average warming in the city, suburban, and mountainous areas of around 2.5°C, 0.6°C, and 0.4°C, respectively within 100 years from 2009.

Abstract

Penelitian ini melaporkan penerapan pemodelan hidrologi, HEC-HMS, terintegrasi dengan Sistem Informasi Geografis (GIS) untuk mengkaji hubungan curah hujan dan debit aliran dengan kasus DAS Ciliwung Hulu. Data spasial curah hujan yang diperoleh dari data radar digunakan dalam proses simulasi curah hujan-debit aliran dan hasilnya dibandingkan dengan hasil simulasi menggunakan data curah hujan hasil observasi. Analisis hasil simulasi curah hujan-debit aliran dianalisis dengan pendekatan spasial, yaitu membandingkan perbedaan dan persamaan antar sub DAS. Simulasi dilakukan untuk kejadian banjir tahun 2002, 2007 dan 2013. Hasil simulasi curah hujan-debit aliran dengan menggunakan data radar hujan, menunjukkan bahwa sub-DA CiLiwung (Tugu) merupakan sub-DAS yang memberikan debit dengan volume tertinggi pada kejadian banjir bulan Januari - Februari tahun 2002 dan 2007 serta tanggal 16 - 17 Januari 2013 yakni masing- masing sebesar 117 mm, 124 mm dan 46 mm. Faktor karakteristik fisik DAS berupa kemiringan DAS, penggunaan lahan, jenis tanah, dan besarnya curah hujan menjadi faktor yang menentukan tingginya debit aliran. Hasil validasi menggunakan metode RMSE dan Nash menghasilkan nilai simpangan yang kecil terhadap data observasi. Hal tersebut menunjukan bahwa penggunaan data radar cuaca dapat diandalkan dalam mensimulasikan hujan-debit.

Abstract

. This study reports the applicability of hydrological modeling, HEC-HMS, integrated with Geographic Information Systems (GIS) to examine the rainfall - runoff relationship with a case study of Upper Ciliwung watershed. Spatial rainfall data derived from radar data used in the process of simulating rainfall - runoff and the results are compared with simulation results using the observed rainfall data. Analysis of the rainfall-runoff simulation was conducted based on spatial approach by comparing the differences and similarities between sub catchments. The simulations carried out for the flood events in 2002, 2007 and 2013. The results of the simulation of rainfall - runoff using C-Dopller weather rainfall radar data shows the sub-watershed of Ciliwung (Tugu) produced discharge with the highest volume in January - February 2002 and 2007, and also 16 - 17 January 2013, i.e. 117 mm, 124 mm and 46 mm, respectively. Physical characteristics of the watershed such as slope, land use, and soil type, are the factors that determine the high discharge value. The results of validation using RMSE and Nash produces small deviation value of the observation data. It shows that the use of weather radar data is reliable in the rainfall-runoff simulation in the Upper Ciliwung watershed

Abstract

A numerical ocean modeling study using spectral element method is used to simulate the Indian Ocean Kelvin wave propagation along the Makassar Strait and the Sulawesi Sea by giving a-prescribed-50-day Kelvin wave forcing in the northern mouth of the Lombok Strait. The least square fit analysis is employed to extract a-50-day-resonant signal from the interface height data simulation. The results indicate that the 50-day Kelvin wave propagates northward along the Makassar Strait. One part of this wave turns back at the Labani channel and makes southward propagation along the eastern coast of the Makassar Strait. The rest part is going further to enter the Sulawesi Sea and makes 50-day resonance within the basin. This finding will have important implication on the intra-seasonal time scale variability of the Indonesian throughflow transport entering the Indonesian Seas and needs further investigation as well as comparison with observational data.

Abstract

Pasien yang sementara di rawat di ruangan intensif care unit terutama yang terpasang ETT sangat beresiko mengalami penurunan saturasi oksigen, sehingga perlu di lakukan tindakan Deep Suction. Deep suction yaitu penghisapan sekret yang dilakukan melewati batas pipa endotrakeal, akibat dari tindakan ini dapat terjadi perubahan saturasi oksigen selain itu pula dapat terjadi perubahan hemodinamik pasien. Saturasi oksigen merupakan ratio antara jumlah oksigen yang terikat oleh hemoglobin terhadap kemampuan total hemoglobin darah mengikat oksigen. Alat yang dapat digunakan untuk mengukur tingkat saturasi oksigen yaitu pulse oximetry.Desain penelitian yang digunakan yakni pre-experimental design dengan jenis rancangan One group pretest-postest. Jumlah populasi 30 pasien dengan teknik pengambilan sampel total sampling. Dengan sampel 30 pasien yang sementara dirawat di ruang ICU RSUD Tani dan Nelayan Kabupaten Boalemo. Instrumen yang digunakan yakni lembar observasi dan SOP serta di lakukan uji normalitas shapiro wink, data tersebut dilakukan uji alternatif wilcoxon. Di dapatkan hasil dengan nilai P = (0.002<0.005). Sehingga dapat disimpulkan terdapat pengaruh deep suction terhadap perubahan saturasi oksigen pada pasien yang terpasang ETT di ruang ICU RSUD Tani dan Nelayan Kabupaten Boalemo.
