Abstract

Air pollution dispersion is not only affected by emission source but also by meteorological factor that is involved. Local meteorological factor will change the air pollution dispersion pattern both in urban area and inanother region. Concavity and valley topographic condition in Bandung city will enable temperature inversion and bring about air fl ow back circulation, causing CO pollutant accumulation. CO is one of the primary pollutants that emits directly from the emission source. It is colorless and odorless gas, posseses longer lifetime which is 30-90 days in the troposphere, and also reduces bodys capability of oxygen absorbance, forming carboxy haemoglobin when being inhaled by human. CO concentration monitoring has been conducted by building and designing CO measurement system equipped with temperature and oxygen monitoring. This integration system consists of sensors (over CO, temperature and oxygen), GPRS modem interface module, sensor interface module, webserver and compilation data system completed with graphical visualization of the CO concentration and surface temperature data every 15 minutes. Analysis on CO concentration trend and observation on surface temperature will become references for the research on local meteorological infl uence toward CO ambient concentration.

Abstract

Dalam rangka mendukung program pengembangan roket sonda LAPAN, telah dikembangkan muatan pengukur atmosfer untuk roket sonda RSX-100 beserta metode pengujiannya yang terdiri dari pengujian sistem sensor dan jangkauan sistem telemetri, pengujian ketahanan muatan, pengujian pelepasan muatan dan pembukaan parasut, pengujian integrasi roket, dan peluncuran muatan pengukur atmosfer bersama RSX-100. Berdasarkan hasil pengujian, sistem telemetri dengan link margin sebesar 50,76 dB untuk jangkauan 8 km telah berhasil mengirimkan data sensor tekanan dan GPS hingga ketinggian 11 km. Frekuensi natural muatan yang sebesar 80 Hz sangat aman terhadap munculnya resonansi dengan frekuensi natural roket. Muatan juga telah teruji ketahanannya terhadap getaran, hentakan, dan percepatan yang diperkirakan akan terjadi saat roket terbang. Sistem pelepasan muatan dan pembukaan parasut juga telah teruji mampu mengeluarkan parasut dan muatan dari dalam tabung roket dengan waktu yang dibutuhkan oleh parasut dan muatan untuk keluaran dari tabung setelah proses separasi roket adalah sekitar 5 detik atau tinggijatuh sekitar 30 meter. Kecepatan turun parasut membawa muatan diperkirakan sekitar 5 hingga 6 m/s. Sedangkan lama waktu lock kembali GPS setelah keluar dari tabung roket adalah 5 detik. Dari hasil uji terbang bersama RSX-100 dengan lama terbang 60 detik, muatan tidak berhasil keluar dari tabung karena roket gagal separasi sehingga hasil pengukuran adalah data kondisi di dalam roket. Data yang berhasil direkam menunjukkan apogee setinggi 5622 m.Kata kunci: Roket sonda, RSX-100, Muatan pengukur atmosfer, Metode pengujian.

Abstract

Indonesia mempunyai banyak daerah rawan banjir dan tanah longsor sehingga diperlukan sistem peringatan dini terhadap bencana tersebut. Radar cuaca merupakan salah satu alternatifnya, akan tetapi harganya mahal, sehingga diperlukan radar cuaca alternatif yang biayanya murah. Dalam penelitian ini dilakukan analisis kemampuan radar navigasi laut Furuno 1932 Mark-2 sebagai solusi radar cuaca biaya murah dengan menganalisis spesifikasinya kemudian membuat eksperimen dan pengujian untuk mencoba solusi kelemahannya melalui pengembangan sistem akuisisi dan pengolah sinyal radar. Menurut spesifikasinya, unit scanner radar memenuhi syarat untuk pendeteksian hujan, hanya membutuhkan koreksi volume untuk lebar berkas vertikal yang lebar. Sedangkan unit display-nya belum memenuhi karena plotter-nya masih satu warna dan penghilang clutter-nya menganggap hujan sebagai clutter. Dari hasil eksperimen dan pengujian dapat diketahui bahwa radar ini mampu digunakan untuk mendeteksi pergerakan hujan dengan nilai reflektivitas yang terpantau antara 15-30 dBZ. Hasil pengukuran rain gauge menunjukkan pada reflektivitas 30 dBZ tersebut terpantau hujan dengan intensitas 5,4 mm/jam. Hubungan antara (Z) dan (R) yang terdeteksi tidak sesuai dengan persamaan Marshall Palmer, karena nilai 30 dBZ menghasilkan intensitas hujan 2,7 mm/jam. Oleh karena itu dalam penelitian selanjutnya perlu dicari hubungan Z dan R yang sesuai untuk radar ini melalui kalibrasi nilai reflektivitas menggunakan data hasil pengukuran rain gauge.

Abstract

This research developed network of two Santanu rain radars of the Center for Atmospheric Science and Technology LAPAN installed in Bandung (SANTANU 1) and Sumedang (SANTANU 2). The objective is to get larger coverage area which also comply data each other. The first step is data optimation to each radar detection results, particularly due to rain attenuation, and then validation with the transportable radar image. The shape analysis on a rain object detected in the slice of both radar images indicates 0.8672 of R2 which show the width of both objectcs has a good similarity. Data optimation due to rain attenuation using attenuation correction for regional weather radar (KA) and path-integrated attenuation (PIA) indicate that the reflectivity improvement by KA is 10 times better than PIA. The object detected by Santanu rain radar is similar to the transportable radar for reflectivity larger than 30 dBZ.  The next step is integration of both rain radar images to create mosaic image and then validation using the transportable radar data. The production of the mosaic image is tried out using three methods: image stitching, averaging, and Cressman scheme. The best result is presented by Cressman scheme which show more integrated slice area and maintain the features of the object. However, the processing time of this scheme is 17 minutes which is longer than  image stitching method. The processing time depend on the number of grid data and the hardware memory. Validation on the mosaic result by using transportable radar data by implementing structural similarity index (SSIM) method yields 0,32 of average value. The improvement on SSIM value is obtained if speckle removal is applied by recording 59% of enhancement

Abstract

A fixed instrument for CO2 measurement (LPN SATKLIM-1B) has been built and installed at LAPAN Bandung, started by using a direct recorder system on the computer then it is completed with data connection to the CO2 monitoring web server. The CO2 sensor used by NDIR technology has been corrected by the temperature and pressure compensation. The sensor was installed on 15 m above ground level, acquired and also recorded its data by monitoring the software developed by using the Microsoft Visual Basic 6.0. From the recording result of measurement data in Bandung from 2008 until 2009, with one minute interval data, it was obtained that the data characteristic compared to the measurement data from Global Atmospheric Watch (GAW) station in Kototabang (using spectroscopy technology) and Mauna Loa, all of them have the same pattern. From one year analysis (2008 – 2009) it was also obtained that by the increase of motor vehicle in Bndung for about 226,500 vehicle a year, 76% land building, and just 8.7% green open spaces, the CO2 has increased 1.5 ppm and the temperature from AWS data 2008-2009 (a year) data has increased 4.3ºC. In another side, the CO2 multiplication effect has occurred at 06.30-08.00 AM according to surface and vertical profile measuremens, due to stable atmosphere and calm wind.

Abstract

In Indonesia, significant variations in rainfall are a severe challenge, especially in the Special Capital Region (DKI) Jakarta, which is very vulnerable to flooding and the effects of climate change compared to other coastal areas in Southeast Asia. This flood caused considerable losses to society, industry, and government. Inaccurate predictions of rainfall lead to difficulties in anticipating floods and landslides, causing an expansion of the impact of these disasters. Therefore, a solution such as "Extreme Rain Index Prediction Information System and Rain Radar-Based Flood Potential Warning System for Jakarta” is needed. This system uses SANTANU rain radar and GSMaP satellite data to visualize real-time rainfall with Server-Sent Event (SSE) techniques. It also employs a Random Forest model to predict extreme rainfall and potential flooding by combining the output from PyStep-based radar nowcasting and Numerical Weather Prediction (NWP). Even though the predicted flood potential is accurate (93.75% accuracy, AUC 0.93), the prediction of flood movement using PyStep is not precise (RMSE 2.8, IoA 0.57), affecting the accuracy of the flood potential prediction. This system visualizes rain from SANTANU and GSMaP radars in real time and estimates the potential for flooding. Further efforts are needed to improve predictions of flood movements for better accuracy of flood potential information.
