Abstract

Nitrogen dioxide (NO2) contributes greatly as a precursor to a number of harmful secondary air pollutants including nitric acid, the nitrate portion of secondary inorganic aerosols and oxidants including ozone. Nitrogen dioxide gas (NO2) is an ambient air pollutant along with the element nitrogen monoxide (NO) which is usually produced from human activities such as burning vehicle engine fuel, burning rubbish, burning coal and industry. This research aims to monitor the quality of air pollution in industrial areas in East Jakarta. The NO2 content in the air can be determined using the UV-Vis spectrophotometer method based on SNI 7119-2: 2017. The principle of NO2 testing uses a UV-Vis spectrophotometer based on SNI 7119-2: 2017. From the results of the tests carried out, it can be concluded that the NO2 level obtained in sample 1 was found to be 25,153 µg/Nm3, in sample 2 the NO2 level was 28,371 µg/Nm3, in sample 3 the NO2 level was 107,022 µg/Nm3, in sample 4 the NO2 level was 29,720 µg/Nm3. Nm3, and in sample 5 the NO2 level was 83.446 µg/Nm3. Based on PP RI No. 22 attachment VII of 2021 concerning air pollution control, the quality standard for NO2 is 200 µg/Nm3 for 1 hour. So it can be concluded from the results of the tests that have been carried out that the NO2 levels in the environment are still below the quality standard, which means that it is not a source of NO2 pollution, is safe and meets the requirements for human health and the environment.

Abstract

Red onion (Allium ascalonicum L.) is a horticultural plant needed by household consumers as a complement to cooking spices and traditional medicines. Shallot production does not meet market demand in Riau, so it is necessary to bring in shallots from other regions. Efforts to increase shallot production continue to be made to meet market demand in Riau. One of the efforts that can be made to increase the production of shallot plants is through the use of natural growth hormones (ZPT). This research aims to determine the respective effects and interactions of giving concentrations of coconut water and NPK fertilizer on the growth and yield of shallot production. This research is a factorial experiment prepared using a completely randomized design (CRD) consisting of 2 factors, namely the concentration of coconut water and the dose of NPK fertilizer. Factor I: Coconut water concentration which consists of 4 levels, namely: A0 = without coconut water, A1 = 50% coconut water (500 ml coconut water + 500 ml water), A2 = 75% coconut water (750 ml coconut water + 250 ml water) and A3 = 100% coconut water (1000 ml coconut water). Factor II: NPK fertilizer dose consisting of 3 levels, namely: N1 = NPK 125 kg.ha-1, N2 = NPK 250 kg.ha-1, and N3 = NPK 375 kg.ha-1. . Data from the analysis of variance were further tested using Duncan's multiple range test at the 5% level. The research results showed that the combination of coconut water with a concentration of 100% and NPK fertilizer with a dose of 250 kg.ha-1 increase plant height, increase tuber diameter, increase fresh tuber weight per m2 and weight of storable tubers per m2.
