Abstract

Gunung Pasang River is as raw water supply for the human activity. However, it is utilized as waste disposal from community activities, agro-tourism, and rubber factories. These activities have the potential to reduce water river quality. The efforts to river pollution prevention that can be taken are to examine for capacity of the rivers to reduce pollutant naturally. The research focused to analysis the pollution load, oxygen dissolved distribution (deoxygenation and reoxygenation rate), and the total pollution load of the Gunung Pasang river utilized the Streeter-Phelps formula. The study was conducted in November – December in 2019 at the Gunung Pasang River with a river length of 300 m which was divided into 3 segments with 4 monitoring points (GP01, GP02, GP03, GP04). Analysis of the parameters i.e. DO and BOD to measure the water quality degradation in the river and the resulting graph of oxygen reduction. The method refers to Minister of the Environment Decree no. 110/2003.The results showed that the average pollution load value was 6.32 kg/day. The range of deoxygenation and reoxygenation rates is 2.67 - 5.36 mg/L.day and 32.77 - 64.71 mg/L.day respectively. The Reoxygenation rate was greater than deoxygenation. This phenomenon reflected that the Gunung Pasang River has a good self – purification performance. The average pollution load capacity of the river is 2.17 kg/day.Keywords: total pollution capacity; oxygen distribution; self – purification; water quality monitoring.

Abstract

Coffee plantation areas have the potential to absorb carbon dioxide in the atmosphere to reduce the greenhouse gas (GHG) emissions. Especially if coffee plantations are developed with forest plants in agroforestry area within forest management patterns. On the other hand, some coffee agroforestry now, are planted with horticultural crops that can reduce carbon sequestration ability to reduce climate change impact. The objectives of the study are to identify the parameters of the abiotic environment and the potential for carbon storage in robusta coffee agroforestry at Argopuro mountains, Bondowoso Regency. Through the calculation of plant biomass and carbon stock, it is potential to approach the amount of carbon uptake in plants to reduce carbon emissions in the atmosphere. Coffee plantation is one area that can increase carbon sequestration in the atmosphere. The results showed that microclimate parameters at robusta coffeeagroforestry at Argopuro mountains in Bondowoso regency i.e. temperature, air humidity, light intensity has average values of 29.2 oC; 54%; and 2166 lux respectively, then an average of soil pH is 6.00. There were some commonly plants founds in robusta coffee plantation i.e mango trees, avocado trees, dadap trees, pine trees, and more banana plants. Total biomass estimation in robusta coffee plantation area is 144,834 tonnes/ha. The identification of carbon stock show that the robusta coffee agroforestry area with ??2000 m2 can contribute to reduce atmospheric carbon emissions by 72.417 tonnes/ha in Argopuro mountains, Maesan District, Bondowoso Regency. Keywords: Argopuro Mountains; Bondowoso; Carbon stock; Coffee agroforestry; Climate Change.
