Published: March 2021

Abstract
Cypermethrin is known as synthetic pyrethroid (SP) which works to interfere the nervous system with a molecular formula of C9H11C13NO3. The use of pyrethroid pesticides which tends to be high and continuous without regard to the rules of pest control can have a negative impact, that is decreasing environmental quality and decreasing biodiversity. Pollution degradation in the soil due to pesticide residues can be done biologically by doing remediation technology. One of the microorganisms that can degrade insecticide residues in the soil is bacteria. Thiobacillus sp. and Clostridium sp. are insensitive to cypermethrin which has been prove by no inhibition zone formed on a media that contained cypermethrin. Therefor this research the aim is to determine the growth response of bacterial culture using Thiobacillus sp. and Clostridium sp. as a bioremediation to remove the insecticide cypermethrin in liquid media. Optimization of environment conditions use temperature with a variation (°C) of 25-40 and concentration of cypermethrin with a variation (ppm) of 100-250 cypermethrin analysis using the Gas-Chromatography Mass Spectrometer (GC-MS). This research proves that the bacterium Thiobacillus sp. and Clostridium sp. capable of removing cypermethrin in liquid media reaching 97% occurs at optimum conditions at 30°C and optimum concentration of 100 ppm.

Abstract
Many urban river water qualities in Indonesia have decrease due to both domestic and non-domestic wastewater discharges. One effort in restoring the river quality is by modeling of the river to determine the most appropriate actions to take. At present many river modeling have been carried out in order to restore river water quality. However, implication of modeling utilization is still insignificant. This study aims to investigate the application of water quality modeling in Indonesian urban rivers. Methods used in this study including expert interviews, previous research review, and data analysis. The research result gives condition that modeling is merely applied in limited function. Stakeholders sometimes doubt the modeling results. It is caused by several aspects of uncertainty, such as river discharge fluctuation, unstable pollution concentration, etc. In addition, the model used is often obtained from sub-tropical area, so there is a disparity of conditions with the environment in Indonesia. Nevertheless, water quality modeling plays an important role in environmental impact assessment as a prediction tool in Indonesia.

Agricultural air pollution in Indonesia: A mini-review
Authors: Lu’ayi A F , Lestari P 
Published: March 2021

Abstract
Indonesia is an agricultural country that is a majority of the population consuming rice, corn and sugar cane for daily energy. But farmers tend to do open burning to their agricultural waste. The open burning practice of agricultural waste is filled with PM2.5 which contributes to air pollution. The research of air pollution modelling in Indonesia often uses the default value of global inventory. This gives the modelling results that are less representative of the situation in Indonesia. Therefore, it is necessary to develop a PM2.5 emission inventory from the agriculture sector in Indonesia. In addition, the inventory of PM2.5 emissions from the agricultural sector in Indonesia is still relatively minimal. In addition, most of research in Indonesia still focuses on agricultural burning activities and has not been able to identify the PM2.5 emissions from the preparation of agricultural land activities. In fact, according to international research, the two largest emissions of PM2.5 on the agricultural sector came from agricultural biomass burning activities and the preparation of agricultural land. Therefore, a comprehensive inventory study need to be investigated immediately in order to determine local factor emission as a better representatives input for agricultural air pollution modelling in Indonesia.
