Abstract

Urine contains a high concentration of nutrients that could increase water pollution and corrosion in the sewerage system. Along with the decrease in global phosphorus reserves, this condition may aggravate the worldwide population’s vulnerability in food security, drinking water, sanitation, and hygiene. This paper aims to gain more knowledge on the importance of urine recovery from municipal wastewater. The previous implementation of the urine separation system, the importance of urine diversion, the potential product, and technologies for urine recovery was briefly described. Overall, urine diversion is expected to address those environmental problems by reducing water pollution and organic loading in wastewater treatment plants, providing valuable nutrients for agricultural production, and lessening the economic cost of improper sanitation.

Abstract

The largest emission from the petroleum production process is dominated by nitrogen oxide (NOx) gas which accounts for 60% of the total emissions. In this research, an assessment of the impacts that occur from petroleum production activities is carried out using the Life Cycle Assessment (LCA) method. In this study, the identification of environmental impacts was carried out using the SimaPro 9 application software and the midpoint-based assessment. In the midpoint assessment, 1 method is used, namely the CML-IA Baseline method. Life cycle impact assessment (LCIA) or impact assessment using midpoint assessment includes global warming, human toxicity, photochemichal oxidation, ozone layer depletion, acidification, eutrophication, abiotic depletion, and abiotic depletion (fossil fuel). Emissions analyzed include CO2, CH4, NOx and SOx. In this study, the scope of analysis used from the process system is cradle to gate. The results of the analysis resulted in the greatest impact value coming from unit A power generator. The largest impact category from the CML-IA Baseline method is acidification. The results of the sensitivity check analysis resulted in the value of both variations above 10%, namely 16% of each variation. The recommended alternative program scenario is cogeneration technology and nonselective catalytic reduction (NSCR) because it can reduce acidification by 69.81%, eutrophication 69.82% and human toxicity 69.40%.

Abstract

Fisheries activities produce wastewater with high levels of BOD, COD, and TSS that are dangerous if discharged directly into the river. One of the treatments that can be done is by using phytotreatment or processing using plants. The plants used in this study are Salvinia molesta and Pistia stratiotes. The stages of this research are propagation, acclimatization, range finding test, and phytotreatment test stage. The fisheries sector wastewater used in this study came from UPT Pasar Gresik with a pH of 6.54, BOD 310 mg/L, COD 853.3 mg/L, TSS 590 mg/L and UPT Pasar Giri wastewater with a pH of 6.48, BOD 292 mg/L, COD 746.6 mg/L, TSS 440 mg/L. Based on the RFT test, Pistia stratiotes is able to survive at a concentration of 20% for Gresik Market wastewater and 40% for Giri Market wastewater while Salvinia molesta can survive at a concentration of 10% for Gresik Market wastewater and 10% for Giri Market wastewater. From the phytotreatment test, the results obtained for the removal of BOD, COD, and TSS parameters in Giri Market wastewater, Pistia stratiotes plants are more effective in reducing BOD levels by 84.6% and COD 80.6% while for TSS levels Salvinia molesta plants are more effective with a removal of 89.8%. Then for the removal of BOD, COD, and TSS parameters in Gresik Market wastewater, Pistia stratiotes plants are more effective in reducing BOD levels by 92.4% and COD 84.4% while for TSS levels Salvinia molesta plants are more effective with a removal of 90.9%.

Abstract

The increase in production capacity of an industry is directly proportional to the amount of B3 waste generated. PT Pupuk Kalimanta Timur at the largest NPK and urea fertilizer producer in Asia certainly also produces waste, one of which is hazardous waste. B3 waste requires special management before being returned to the environment given the dangers and impacts caused, starting from the source of B3 waste generated until it is dumped or buried. This study aims to identify and evaluate the management of B3 waste by comparing the management of B3 waste carried out by the company with applicable regulations and providing suggestions and recommendations and estimating the costs required for the construction of B3 waste TPS. Based on this research, there are still several discrepancies in the implementation of B3 waste management with applicable regulations, namely in storage and transportation activities. The amount of B3 waste generated in a period of 3 months is 115,662 kg or equivalent to 152 pallets. With the capacity of the existing B3 Waste Temporary Storage Site (TPSLB3) can only accommodate 228 pallets with an increase in production capacity, the existing TPS cannot accommodate all the waste generated so that a new B3 waste TPS building with the appropriate capacity is needed. The planned TPSLB3has dimensions of 26 m x 12 m x 5 m with a capacity of 112 pallets. The TPSLB3 is already equipped with supporting facilities such as a catch basin, safety shower, fire extinguisher, emergency exit, and lightning rod and is in accordance with applicable standards and regulations. The construction of the B3 waste TPS costs Rp 893,039,000.

Abstract

NO2 concentrations in vehicles or near highways are much higher than those measured on monitors in the current network. Some measurements in highway and terminal areas are reported to exceed the established quality standards although some areas of NO2 concentrations are below the quality standards but from surveys and data analysis show a risk quotient value of more than 1 indicating that it is not safe to be in the area for the next 30 years. One method to reduce NO2 concentration is titanium dioxide (TiO2) illuminated by UV, the presence of UV can be studied related to the reduction of microorganisms. The research was conducted with the study of ultraviolet intensity on TiO2 photocatalyst in reducing NO2 and UV intensity on microorganisms. The data taken is secondary data. This was followed by finding design criteria, followed by material selection. Dimensional calculations are carried out based on the material and criteria determined, then the estimated reduction efficiency on NO2 and microorganisms can be carried out and adjusted to the quality standards of PerMenKes No. 1077 of 2011. The estimation results show that the room ventilation design using an intensity of 75.8 mW/cm2 on TiO2 photocatalyst is able to reduce NO2 by at least 52.53% with an inlet concentration of 0.067 ppm. The use of an intensity of 75.8 mW/cm2 in the space ventilation design was able to reduce microorganisms with a UV D90 dose value below 238.77 J/m2. The space ventilation design is estimated to be sufficient to supply home room air under non-smoking conditions with NO2 reduction results according to the standard and close to microorganisms.

Abstract

This study uses an Arduino Uno-based IoT air monitoring device with MQ-135 sensor and MQ-136 sensor. Arduino Uno is a microcontroller board based on ATmega328 (datasheet). It has 14 input pins of digital output where 6 of them can be used as PWM output and 6 analog input pins, 16 MHz crystal oscillator, USB connection, power jack, ICSP header, and reset button. To support the microcontroller to be used, the Arduino Uno Board is connected to a computer using a USB cable or electricity with an AC-to-DC adapter or battery to run it. The MQ-135 sensor type is one of the sensors that can detect CO2 gas levels. This sensor has low conductivity when placed in clean air. Then the MQ-136 sensor type is a sensor that has high sensitivity to SO2 gas, this sensor can also be used to detect other vapors containing sulfur gas. In both sensors there is a resistance value (Rs) that can change when exposed to gas and also a heater that is used to clean the sensor room from outside air contamination. The output of the two sensors is in the form of analog data. The ESP8266 is a Wi-Fi Smart on Chip (SoC) that is designed to be minimalist in size and uses very little external circuitry. The chip can communicate over wifi infrastructure using IPv4, TCP/IP, and HTTP protocols. The results of the MQ-135 and MQ-136 sensor readings on the microcontroller device show quite good values and also meet the existing quality standards. The MQ-135 sensor for CO2 gas readings has an average result of 314 ppm. The MQ-136 sensor for SO2 gas readings has an average value of 0.015 ppm. The working system on Android that is used uses the Blynk Apps application by making coding for LCD, LED, buzzer, and sensors that are connected to smartphones via wireless. The use of the value feature as real-time data has been able to monitor and provide air quality notifications via smartphone or email.

Abstract

PT. X has conducted a Life Cycle Assessment (LCA) study in 2019. However, it has not been proven that the air emission reduction program that has been implemented is effective in reducing the environmental impacts that occur. In this study, the LCA study is continued to identify the largest environmental impacts that occur and hotspot units after implementing the air emission reduction program and determine the effectiveness of the program. SimaPro software was used to conduct the LCA analysis, with a midpoint approach and using the CML-IA Baseline method. Based on the LCA analysis, the biggest environmental impacts that occur at PT X are acidification in SP A, B, C and global warming (GWP100a) in SP D. the air emission reduction program that has been implemented since 2019 has effectively reduced the impacts that occur. The recommended improvements to reduce the impact of acidification and global warming are replacing diesel engines with gas engines, installing Non-Selective Catalytic Reduction (NCSR), utilizing flare gas into compresses natural gas, and enhancing oil recovery using carbon capture separation technology to capture CO2 gas.

Abstract

The population growth of Trenggalek sub-district has an impact on the increase in waste generation. However, waste reduction carried out through the implementation of TPS 3R Sawunggaling with a facility area of 362.5 m2 only manages 40% - 45% of incoming waste so that development is needed. The objectives of this planning include: evaluate the existing condition of waste management; identify waste generation, density, and composition; and plan the development of organic waste processing using Black Soldier Fly in technical and financial aspects at TPS 3R Sawunggaling. Sampling activities were carried out using the load-count analysis method and obtained data on waste generation, density, and composition of TPS 3R Sawunggaling. Technically, the planning was carried out by determining the service coverage of TPS 3R Sawunggaling, analyzing mass balance, planning the addition of organic waste processing facilities by BSF, and calculating labor requirements. Financially, the feasibility of planning is determined using the Net Present Value (NPV) method by calculating investment costs, operational and maintenance costs, and potential income. Based on the evaluation results, waste management at Sawunggaling TPS 3R needs improvement in terms of waste segregation at the source, adding a fixed schedule for waste collection, and increasing compost production. The waste generation and density of Sawunggaling 3R TPS were found to be 0.67 kg/person/day and 204.91 kg/m3. The waste composition is dominated by organic waste at 83.7% while the rest is inorganic waste. By utilizing the potential of organic waste entering Sawunggaling 3R TPS, it is planned to develop organic waste processing by adding a composting method using BSF larvae. In the planning year, Sawunggaling 3R TPS serves 1,268 people with waste generation of 864.34 kg/day. Through this planning, the residue of Sawunggaling 3R TPS was reduced from 57.9% to 24.6%, thus reducing the waste that is transported to the final processing site (TPA). In managing this facility, Sawunggaling 3R TPS requires an investment cost of Rp. 34,271,157.60, an operational cost of Rp. 217,601,983.80/year, and will generate a potential income of Rp. 434,747,586.62/year. From these costs, a positive NPV value is obtained, which means that the development planning is financially feasible.

Abstract

Naturally the water temperature is correlated with the density and viscosity. Changes in temperature due to sunlight affect processes in water treatment such as sedimentation and coagulation. The detrimental effect is the presence of density currents on the surface during the day, thereby reducing the efficiency of particle sedimentation. Vegetation Canopy can be applied in sedimentation tanks to cope with changes in temperature on the surface of the water mass. This method can be implemented by planting trees around the tank in addition to fabric fiberglass. Tall trees and canopies with large leaves will cover the surface area of ​​the sedimentation tank so that changes in water temperature due to sunlight can be reduced. To apply this technique, submerged orifices and a net above the water surface are used at the outlet channel of the sedimentation basin.

Abstract

Salah satu pengolahan air payau adalah adsorpsi. Dalam penelitian ini, dua jenis zeolit dibandingkan sebagai adsorben. Zeolit A diperoleh melalui aktivasi fisik dengan pemanasan pada suhu 600 oC. Zeolit yang termodifikasi menggunakan surfaktan HDTMA-Br akan menghasilkan Zeolit B. Kedua jenis zeolit tersebut dikarakterisasi menggunakan SEM, XRD, dan PSA. Hasil analisis PSA menunjukkan bahwa Zeolit B memiliki luas permukaan, volume, dan ukuran pori yang lebih tinggi dibandingkan Zeolit ​​A. Aktivitas adsorpsi diukur berdasarkan penghilangan salinitas, kekeruhan, TDS, dan konduktivitas pada berbagai massa adsorben dan waktu adsorpsi. Hasil penelitian menunjukkan Zeolit A mampu menurunkan salinitas sebesar 15,38% dalam waktu 30 menit dan massa 6 gram. Zeolit B sebanyak 4 gram mampu menghilangkan salinitas 17,31% sekaligus. Rendahnya rasio nilai Si/Al menyebabkan kapasitas adsorpsi menjadi lemah. Air terproduksi juga belum memenuhi standar persyaratan air bersih dan air minum.
