Climate change is a global issue that is of concern to the world. One of the impacts of climate change is sea level rise. Rising sea levels can cause tidal floods, especially in coastal areas. Based on data from the Meteorology, Climatology and Geophysics Agency (BMKG), one evidence of climate change is an increase in sea level. Satellite altimetry measurements show a trend of sea level rise in Indonesia from 1992-2022 averaging around 4 mm/year. Rising sea levels have an impact on increasing the frequency of coastal flooding, retreating coastlines, and the disappearance of national borders. The city of Surabaya is one of the coastal cities in Indonesia which has the potential to experience an increase in the height of tidal floods due to climate change. The potential for tidal floods due to climate change could harm the spatial planning of coastal areas in Surabaya. The results of this research show that the coast of Surabaya has a moderate level of tidal flood vulnerability with an area of 8230.77 ha, a high category with an area of 1739.21 ha, and a very high category with an area of 178.13 ha. The area is dominant from most of the coast of the Semampir subdistrict to Benowo and the border of the Bulak and Mulyorejo subdistricts. Tidal floods can cause the submergence of productive lands, such as settlements, fish farms, and warehouses. This can cause economic and social losses for coastal communities. Therefore, adaptation efforts are needed to reduce the impact of tidal floods due to climate change. These adaptation efforts can be carried out through improving spatial planning and environmental planning for coastal areas.

The application of Personal Protective Equipment (PPE) at the Meteorology, Climatology, and Geophysics Agency (BMKG) is an important step in maintaining employees’ safety and health in their work environment. Even though BMKG is not involved in heavy industrial activities, there are still potential hazards and risks that need to be addressed in carrying out meteorological, climatological, and geophysical tasks. This study aims to describe the importance of implementing PPE in the BMKG environment, especially the Aviation Meteorological Station, where we took a case study at the Juanda Meteorological Station. First, we identify potential hazards that may be faced by BMKG employees, such as radiation risk, potential for hazardous gas explosions or fires, extreme weather conditions, and risks of physical injury. In the face of these risks, the use of proper PPE can help protect employees from hazardous exposures, and gas explosions and prevent injury. Next, we discuss the factors that need to be considered in implementing PPE at the BMKG. This includes a comprehensive risk assessment, identification of appropriate PPE for specific hazards, training of employees on the use and care of PPE, and regular monitoring and maintenance of the PPE used. Therefore, by implementing the Occupational Health and Safety Management System, in this case, the application of PPE, BMKG can ensure that employees have a safe and healthy work environment, reduce the risk of work accidents, and comply with applicable regulations and standards related to work safety.

The rapid urban development has increased the density of buildings and decreased the Green Open Space (RTH), thereby affecting the thermal comfort of an area. The level of thermal comfort can be observed from the characteristics of temperature and humidity. The determination of thermal comfort levels, especially in Semarang City, is conducted using the Humidex method. The calculation results show Humidex values ranging from 38.83°C to 41.10°C, categorized as uncomfortable to very uncomfortable. The highest Humidex value was recorded at the Semarang Climatology Station in 2023, while the lowest was at the Ahmad Yani Semarang Meteorology Station in the same year. Meanwhile, Landsat 8 imagery analysis shows that from 2014 to 2023, the total land cover transition in Semarang reached 68.541 km² for buildings; 63.104 km² for tree vegetation; 1.353 km² for other vegetation; and 6.784 km² for water bodies. By the end of the research period in 2023, the area of tree vegetation in Semarang City was 91.187 km². The analysis of the relationship between Humidex values and the area of building cover shows a correlation coefficient of 0.87, indicating an increase in building cover area that has raised the Humidex value in Semarang City. Furthermore, the correlation of Humidex with the area of RTH is -0.83, meaning there is a strong negative linear relationship between the Humidex values and the RTH area, or the larger the RTH cover, the lower the Humidex value in Semarang City. To maintain or improve the level of thermal comfort in Semarang City, it is recommended to balance the distribution of RTH locations, especially in the northern and eastern parts of Semarang. The Semarang City government should enhance the quality of RTH by choosing appropriate vegetation, performing regular maintenance, improving facilities and services around RTH, and continuously educating the public.

Kemunculan awan cumulonimbus dapat menyebabkan cuaca ekstrem seperti badai guntur dan petir. Untuk mengetahui potensi kemunculannya dapat dilakukan dengan mengidentifikasi parameter suhu bola basah dan selisih tekanan udara. Parameter tersebut berpengaruh pada kelembapan udara yang menjadi faktor penting pembentukan awan cumulonimbus. Dalam konteks penelitian ini, periode tahun 2022 diambil sebagai sampel analisis untuk mengetahui pola representatif kejadian cuaca ekstrem akibat kemunculan awan cumulonimbus. Metode penelitian ini menggunakan metode pembacaan data sinoptik melalui buku laporan ME-48. Setelah data di analisis dan diolah menggunakan Microsoft Excel dapat ditemukan kemunculan awan cumulonimbus pada bulan Januari, Februari, Maret, April, Mei, Juni, Oktober, November dan Desember, di mana awan cumulonimbus mulai memasuki tingkat dewasa terjadi pukul 13.00 WIB. Rentang nilai suhu bola basah pada pembacaan pukul 09.00 hingga 11.00 WIB digunakan untuk memprediksi kemunculan awan cumulonimbus adalah 26,1-26,5°C. Sedangkan selisih nilai tekanan udara yaitu pada rentang 1,3-1,6 milibar atau 130-160 Pascal. Penelitian ini diharapkan dapat memberikan peringatan dini terhadap kejadian cuaca ekstrem khususnya di wilayah cakupan Stasiun Meteorologi Maritim Tanjung Perak. Kata Kunci: awan cumulonimbus, suhu bola basah, selisih tekanan udara, cuaca ekstrem, data sinoptik Abstract The appearance of cumulonimbus clouds may trigger extreme weather, such as thunderstorms and lightning. It is possible to predict its appearance by figuring out the wet bulb temperature aspects and the differential in air pressure. These variables have an impact on air humidity, which is an essential element in the occurrence of cumulonimbus clouds. This study employs the 2022 timeframe as a sample pattern of catastrophic weather conditions due to the arrival of cumulonimbus clouds. For this reason, the ME-48 report book was adopted for the synoptic data reading method. Using Microsoft Excel to analyze and process data resulted in the onset of cumulonimbus clouds in January, February, March, April, May, June, October, November and December, with cumulonimbus clouds approaching maturity at 13.00 WIB. The range of wet bulb temperature values used to anticipate the arrival of cumulonimbus clouds is 26.1-26.5°C during measurements from 09.00 to 11.00 WIB. Meanwhile, the air pressure differential lies within the range of 1.3-1.6 millibars (130-160 Pascal). This study is intended to assist in mitigating the consequences of early warning systems for extreme weather, particularly in the immediate area of the Tanjung Perak Maritime Meteorological Station. Keywords: cumulonimbus clouds, wet bulb temperature, air pressure difference, extreme weather, synoptic data
