Abstract

Surabaya is the second most populous city in Indonesia after Jakarta. This led to a high number of motorized vehicles being used, both private vehicles and public vehicles. As the number of vehicles increases, the level of air pollution caused by vehicle exhaust gases also increases. The contribution of motor vehicle exhaust gases as a source of air pollution reaches 60-70% of the total exhaust gases produced from combustion activities. One of the emissions produced from exhaust gases is Lead (Pb). Pb particles resulting from motor vehicle activity come from the combustion of additives used as a mixture of gasoline consisting of Tetraethyl Lead (TEL) and Tetramethyl Lead (TML). High concentrations of Pb can have adverse effects on human, animal, and plant health as well as a decrease in environmental quality. Tabebuia (Tabebuia sp.) and Trembesi (Samanea saman) is one the most planted vegetation in urban parks.
This study aims to determine the content of Pb, the correlation of motor vehicle activity to the content of Pb, and the correlation of the type of city park to the content of Pb in Tabebuia (Tabebuia sp.) and Trembesi (Samanea saman). Sampling is carried out in South Surabaya and East Surabaya as the areas with the highest number of motorized vehicles in Surabaya. This research includes observational research that uses data analysis with descriptive and quantitative methods. This research will be from January to July 2023. Pb content was analyzed using the wet destructive method and ICP measurement.
This research was conducted to find out how is the efficiency of Tabebuia sp. and Samanea saman in absorbing Pb concentration from vehicle exhaust gases and what is the effect of the location of the urban park type on the absorption of Pb from vehicle exhaust gases. The results of the study showed that Tabebuia sp. can absorb lead concentrations of 121.4 – 171.7 mg/kg and for Samanea saman of 90.9 – 138.3 mg/kg. Meanwhile, the location of the urban park type does not significantly affect the amount of absorption of Pb from vehicle exhaust gases.

Kota Surabaya adalah kota terpadat kedua setelah Kota Jakarta. Hal ini menimbulkan tingginya jumlah kendaraan bermotor yang digunakan baik itu kendaraan pribadi maupun kendaraan umum. Seiring meningkatnya jumlah kendaraan, tingkat polusi udara yang disebabkan oleh gas buangan kendaraan pun meningkat. Kontribusi gas buang kendaraan bermotor sebagai sumber polusi udara mencapai 60-70% dari keseluruhan gas buangan yang dihasilkan dari aktivitas pembakaran. Salah satu emisi yang dihasilkan dari gas buangan adalah timbal (Pb). Partikel Pb hasil aktivitas kendaraan bermotor berasal dari pembakaran bahan aditif yang digunakan sebagai campuran bensin (gasolin) yang terdiri dari Tetraethyl Lead (TEL) dan Tetramethyl Lead (TML). Konsentrasi Pb yang tinggi dapat membawa pengaruh buruk bagi kesehatan manusia, hewan, dan tumbuhan serta penurunan kualitas lingkungan. Tabebuia (Tabebuia sp.) dan Trembesi (Samanea saman) adalah salah satu tanaman yang paling banyak ditanam di taman kota.
Penelitian ini bertujuan untuk mengetahui kandungan Pb, korelasi aktivitas kendaraan bermotor terhadap kandungan Pb, dan korelasi jenis taman kota terhadap kandungan Pb dalam Tabebuia (Tabebuia sp.) dan Trembesi (Samanea saman). Pengambilan sampel dilakukan di Surabaya Selatan dan Surabaya Timur sebagai wilayah dengan jumlah kendaraan bermotor terbanyak di Surabaya. Penelitian ini termasuk penelitian observasional yang menggunakan analisis data dengan metode deskriptif dan kuantitatif. Penelitian ini dilaksanakan pada bulan Januari sampai Juli 2023. Kandungan Pb dianalisis menggunakan metode destruktif basah dan pengukuran ICP.
Penelitian ini dilakukan untuk mengetahui bagaimana efisiensi Tabebuia sp. dan Samanea saman dalam menyerap konsentrasi Pb dari gas buang kendaraan dan apa pengaruh lokasi jenis taman kota terhadap penyerapan Pb dari gas buang kendaraan. Hasil penelitian menunjukkan bahwa Tabebuia sp. dapat menyerap konsentrasi timbal 121,4 – 171,7 mg/kg dan untuk Samanea saman 90,9 – 138,3 mg/kg. Sementara itu, lokasi tipe taman kota tidak berpengaruh signifikan terhadap jumlah penyerapan Pb dari gas buang kendaraan.
