Abstract

The geographical location of an area has an impact on the physiological comfort in a residential area. In addition, the rapid development and climate change also have an impact on weather parameters that affect the level of comfort. This research was conducted to determine the comfort level in Banten Province using THI (Temperature Humidity Index) analysis of the parameters of air temperature and humidity. The value of the comfort level is divided using a comfort interval, for THI values between 21-24 °C there are 100% of the population declaring comfortable, THI between 25-27 °C only 50% of the population feels partially comfortable, and THI> 27 °C as much as 100% the population feels uncomfortable. Based on climate data from 1986 - 2009 at Serang Meteorological Station, Cengkareng Meteorological Station and South Tangerang Climatology Station, the results showed an average percentage of daily comfort levels with a comfortable category of 9,5% (35 days per year), some comfortable 79,2% (289 days per year) and uncomfortable 11,3% (41 days per year). During this period, there was an increase in the THI index in Banten Province which tended to be increasingly uncomfortable with the South Tangerang Climatology Station being the most significant area.

Abstract

Research on surface wind patterns has been carried out in an effort to minimize aircraft accidents at Sultan Syarif Kasim II Airport Pekanbaru, Riau. Wind direction and speed data were obtained from synoptic observations of the Syarif Kasim II Pekanbaru Meteorological Station from January to December during 1991 - 2020 (for the last 29 years). The data is then processed using the WRPLOT (Wind Rose Plots for Meteorological Data) application which can show the direction and difference in the magnitude of the wind speed and produce an image of the wind pattern in the form of a wind rose diagram. From the results of this writing, it is known that the dominant wind blows from the south (157 - 202°) with a percentage of 27.18%, then followed by the dominant wind blowing from the Northwest (292 - 337°) with a percentage of 14.68% and then the dominant wind direction from the Southeast (112 - 157°) with a percentage of 9.60%. The dominant wind speed is 6 – 9 knots with a percentage of 48.01%, then dominant with a speed of 3 – 6 knots with a percentage of 34.15%, and calms wind speed with a percentage of 7.23%. The conclusion of this paper is that the condition of the wind direction and speed at Sultan Syarif Kasim II Airport Pekanbaru is still a safe category for the takeoff and landing process.

Abstract

To detect of urban heat island effect in Pekanbaru and to identify climate change, daily temperature data processing of Pekanbaru Meteorological Station in urban area and Japura Rengat Meteorological Station data in the rural region from 1982-2010 (29 years) include: minimum temperature, temperature 07.00 WIB, temperature at 13.00 WIB, maximum temperature and temperature at 18.00 WIB from 1982-2010 (29 years). Performed daily DTR (Daily Temperature Range = Tmaximum - Tminimum) trends, monthly, annual and decadal averages. The effects of urban heat island or urban heat island effect (UHIE) have occurred in Pekanbaru. Some of the indications are: annual average annual DTR decrease of 3.2 ° C per 100 years that does not occur in Japura Rengat. The narrowing of DTR in Pekanbaru is caused more by a very significant annual minimum temperature increase of 5.7 ° C per 100 years which is greater than the maximum temperature rise of 2.0 ° C per 100 years. Minimum temperature rise in Pekanbaru began to occur since 2000 in line with the development of the city. Other indications are significant rise in temperature of 18.00 hours which is 7.6 ° C per 100 years and temperature of 07.00 hours of 6.6 ° C per 100 years.

Abstract

Based on BNPB data, floods and flash floods are the most frequent hydrometeorological disasters in Indonesia in the last 5 years. Where the cause of this disaster in general is high intensity (heavy to extreme) rainfall. BMKG has provided early warning products related to heavy rain and potential floods or flash floods for Indonesia region. One of the potential flash flood products is SAOFFG which has been used as an initial guide for flash flood detection. Using the dichotomous verification method, this study calculates 4 verification indices to measure the performance of the SAOFFG system in detecting floods in Indonesia. The result is that the accuracy of this product is quite satisfactory, but the value of False Alarms still tends to be high, which means that this system still predicts flood potential too high compared to observed flood events, especially in several provinces in central and eastern Indonesia.

Abstract

The stability index can be used by weather forecasters to predict heavy rain events. This paper examines the atmospheric stability index for the occurrence of heavy rain in Bitung City, North Sulawesi, during 2020-2021. Stability index data was obtained from the radiosonde of Sam Ratulangi Meteorological Station, Manado. The indexes studied are the Lifted Index (LI), Showalter Index (SI), K-Index (KI), CAPE, SWEAT, and Total-Totals Index (TT). The results show that heavy rain in Bitung occured when the SI, KI, SWEAT, and TT values are in the moderate category. Meanwhile, the LI and CAPE values are less representative in predicting the occurrence of heavy rain in Bitung City. Further research is needed on the relationship between the threshold value of the atmospheric stability index and the weather in Bitung City so that it can be used as a reference for weather prediction.

Abstract

Hasil Perairan Sulawesi Utara memiliki lokasi strategis yang dikelilingi oleh Laut Sulawesi dan Laut Maluku yang termasuk sebagai pintu gerbang massa air dari Samudera Pasifik, yang memiliki banyak potensi ikan dan daerah penangkapan ikan. Salah satu permasalahan yang secara alami dihadapi nelayan yaitu dampak dari El Nino Southern Oscillation (ENSO) yang dapat mempengaruhi kesuburan laut, variabilitas suhu permukaan laut dan klorofil-a di perairan Sulawesi Utara. Penelitian ini berfokus untuk mengkaji variabilitas parameter oseanografi untuk menentukan daerah penangkapan ikan di Laut Sulawesi dengan menggunakan data satelit AQUA-MODIS, serta menganalisis bagaimana pengaruh ENSO terhadap hasil tangkapan dan CPUE di perairan Sulawesi Utara. Variabilitas parameter oseanografi seperti suhu permukaan laut, klorofil-a, dan angin permukaan dianalisis secara temporal dan uji korelasi antar parameter dengan metode korelasi pearson digunakan untuk mengukur hubungan Indeks Nino 3.4 terhadap Hasil Tangkapan dan CPUE. Variabilitas temporal parameter oseanografi menunjukkan pola yang relatif sama di setiap periode musimnya. Suhu cenderung hangat dan nilai konsentrasi klorofil-a rendah di periode musim barat hingga musim peralihan I, sedangkan pada periode musim timur hingga peralihan II suhu cenderung lebih dingin dan nilai konsentrasi klorofil-a tinggi. Angin permukaan menunjukkan nilai kecepatan angin yang relatif tinggi pada musim timur. Uji korelasi Indeks Nino 3.4 terhadap Hasil tangkapan dan CPUE memiliki hubungan negatif atau berbanding terbalik dan cukup signifikan pengaruhnya.
