Abstract

Abstract. Inadequate processing of waste in household areas has resulted in many people throwing the waste anywhere. Waste generation can be minimized by using the composting method. There are many methods of composting organic waste; one of them is the Tong Composter. Tong Composter is a composting method which in the process uses an EM4 bio-activator. Objectives: This research objective is to determine whether the liquid organic fertilizer parameters produced comply with the standard of Ministerial Decree of Agriculture No. 261 of 2019. Method and results: This research using the experimental method with two treatments, EM4 dosage (60 ml and 70 ml) and fermentation time (10 days and 20 days). A dose of EM4 in treatment 1 is 60 ml, and treatment 2 is 70 ml; each treatment was analyzed on the 10th day. For treatment 3 and 4, a dose of EM4 in treatment 3 is 60 ml, and in treatment 4 is 70 ml; each treatment was analyzed on the 20th day. Then from the liquid organic fertilizer produced, several parameters were analyzed at PT. Sucofindo Cibitung, such as Nitrogen, P2O5, and K2O parameter. Meanwhile, the pH will be measured in the Environmental Engineering Laboratory of President University. The laboratory experiment results from pH, Nitrogen, P­2O5, and K2O will be tested using the t-test. With the hypothesis (HO: µ sample ≥ minimum value of macro-nutrient and pH parameter from Ministerial Decree of Agriculture of the Republic of Indonesia Number 261 of 2019). According to the t-test result, the null hypothesis is rejected because Nitrogen, P2O5, and K2O in all parameters are less than 2%. The null hypothesis is accepted for pH because in all parameters is higher than or equal to 4. Conclusion: The t-test result showed that only the pH was complied with the standard, while the Nitrogen, P­2O5, and K2O parameters have not complied with the standard of Ministerial Decree of Agriculture No. 261 of 2019.

Abstract

Abstract. Intensive water quality determination needs to be adjusted with technological developments to meet today's society's needs and increased water pollution due to urbanization. Therefore, early detection is essential for in site water quality determination and as a critical consideration in making health and environmental decisions. OpenCV is a library programming feature for Computer Vision which focuses on extracting information from images in real-time, this can be considered to be potential to measure the pollutant concentration. Objectives: This study identify the potential of colorimetry analysis method by using OpenCV as an alternative method for pollutant concentration measurement. Method and results: First stage, this study collecting the data of NH3 phenate and Pt-Co CU from the spectrophotometer. The first stage also was including the development of an OpenCV code. Then, the data was collected were processed to get the concentration of NH3 and Pt-Co both using OpenCV and spectrophotometer; factors that influence the Pt-Co sample image measurement process by using OpenCV-Python was analyzed too. Then in the analysis stage, the result of the two measurement method was tested by statistic determine its significant difference. The conclusion found whether OpenCV could be potential to measure the pollutant concentration or not. Conclusion: the OpenCV has potential to be use as alternative colorimetry measurement method to determine water pollutant as there is no significant difference in the spectrophotometric method results and the results from OpenCV for Pt-Co sample.  Meanwhile, in this study found that the result of NH3 from spectrophotometer is nonlinear different with from OpenCV that is linear. Thus, further research is needed to test the validity of OpenCV method.  The factor influence of measurement using OpenCV code is when determining the Region of Interest (ROI) and determining the pixel values for the normalized box filter

Abstract

Abstract. Organic waste processing that has not received more attention and awareness has made the generation of organic waste higher in landfills. One of the ways that can be done to reduce waste generation from the source is by composting. The composer is a simple tool that can be used to compost anaerobically with the help of an EM4 activator to speed up the composting process. Objectives: The purpose of this study was to determine whether the parameters of the liquid organic fertilizer produced had met the standards of the Minister of Agriculture Regulation Number 261 of 2019. Method and results: This study used an experimental method with one treatment, namely fermentation time, 14 days and 20 days. The EM4 dose used for all samples was 60 ml per composter. before use EM4 is activated first by providing a food source in the form of a molasses solution of about 600 ml. Sampling was carried out on the 14th and 20th days, then taken to the Sucofindo Cibitung Laboratory to test the Nitrogen, P2O5, and K2O parameters. Based on hypothesis testing with t test, the content of Nitrogen, P2O5, and K2O were not complied with the standard from Decree of the Minister of Agriculture of the Republic of Indonesia Number 261 of 2019. Conclusion: The parameter of Nitrogen,P2O5 and K2O of organic fertilizer produced does not comply with the starndard of Ministerial Decree of Agriculture No. 216 of 2019.

Abstract

Transportation is the most influential source in increasing levels of carbon monoxide (CO) in the air. Pekanbaru is the capital of Riau province which is experiencing rapid economic development that is a cause of population growth and increasing the number of motorized vehicles. The purpose of this study is to measure CO concentrations from mobile sources then compare them with PP No. 41 of 1999, calculating CO concentrations with the Gaussian Line Source Model, and mapping the predicted distribution of CO emissions on Jalan Jendral Sudirman, Pekanbaru City. The method used is counting the number of motorized vehicles (traffic counting) and measured the concentration of CO and wind speed in the field.  The results showed that the highest CO concentration on Jalan Jendral Sudirman Pekanbaru City was on Tuesday with a concentration of 6603.95 µg/m3 (5.767 PPM) at the sampling point in front of Ramayana Store and 1.4620.3 µg/m3 at the sampling point in front of Sudirman Square, both concentrations are still below the air quality standard based on PP No. 41 of 1999. From the calculation of the model, the concentration obtained in Ramayana for the measurement distance of 0 m was 27.198 µg/m3, at a distance of 5 m was 0.133 µg/m3, and at a distance of 10 m was 0.060 µg/m3. At Sudirman Square, obtained CO concentrations for the measurement of 0 m is 26.869 µg/m3, at a distance of 5 m is 0.131 µg/m3, at  a distance of 10 m is 0.059 µg/m3.

Abstract

Abstract: The problems in the marine and coastal environment have aroused the attention of many countries in the world. According to [1], it is estimated that every year eight million tons of debris find their way into the world's oceans, thus disturbing aquatic and marine ecosystems. Particularly in the case of coastlines, many studies show that the majority of marine litter (60-80%) consists of plastic [2].   The objectives are to evaluate the critical issues in regards to marine environment waste monitoring and to track the development of technology used in the field of marine and coastal debris monitoring problems over the last two decades. The method of this research is by investigating the topic that is quite a lot raised as research related to coastal and marine waste and the distribution of technology implemented for coastal and marine debris. The results show that waste in coastal and marine areas is a problem that needs to be solved immediately. The data relating to the generation of waste flowing into the ocean is dynamic, moving every day, depending on the generation of the generated waste and its accumulation and drifting in the ocean. The large amount of information collected from higher views (such as satellite views) provides important insights for understanding and identifying plastic waste debris pollution and its movement. The conclusion: Regardless of the application, an integrated technical solution is required, which can be sensors, communication devices, data packet transmission from client devices to servers with appropriate application protocols, or a combination of several technologies
