Published: January 2021

Abstract
The emission from industry has become a significant problem in Indonesia. Usually, the enterprise uses an accredited testing laboratory to conduct emission tests to report its process’s environmental performance. In contrast, this testing was accurate, but it cannot visualize whole time emission from one method. This year, the Covid-19 pandemic also gained some difficulties in environmental evaluation in the industry, including emission performance evaluation. Some big companies may have expensive continuous emission monitoring that can substitute manual laboratory testing. Some other, the small and medium scale industry did not have this system. There is a possible development of an integrated low-cost emission monitoring system in the small-medium scale industry. The low-cost gas sensor rapidly develops and gets more accurate. An engineering scenario of integrating low-cost emission monitoring systems into digital information systems could be developed under some challenges, instrumentation, calibration, and regulative support. By applying this scenario, periodical emission concentration can be evaluated periodically to support air quality management policy.

Abstract
Electrocoagulation (EC) is an electrochemical technique in wastewater treatment that generates coagulant species in situ by electro dissolution of the sacrificial electrode. This work aimed to optimize the operating cost of tannery wastewater treatment by EC with iron electrodes under various DC voltages and electricity consumption. The experiment was conducted in a 400 mL batch electrochemical reactor using three iron electrode plates under a mono polar configuration and parallel distances of 26 mm. Several variations of voltage (8; 12; and 16 volt) and electricity consumption (1.7; 2.6; 3.4; and 4.3 kWh/m3) were applied. The reactor performance was evaluated based on the sedimentation curve using Imhoff cone. Simultaneously, the operating cost was analysed based on the electrode mass consumption and electricity consumption under variation in iron electrode price and electricity rates. The result showed that the optimum operating condition was obtained at the electrical voltage of 12 VDC and the electricity consumption of 2.55 kWh/m3. This condition had a current density of 1.7 A/m2, the electrode consumption rate of 0.31 kg/m3, and the operating cost of 0.45 – 0.55 USD/m3.

Abstract
Domestic wastewater is wastewater from household activities such as kitchens, baths, laundry, and water closets. Domestic wastewater contains parameters that can cause environmental pollution, so it needs to be treated. One of the domestic waste treatment technologies is electrocoagulation. Electrocoagulation is a continuous coagulation process using direct electric current through electrochemical events. The purpose of this study was to determine the effect of current on electrocoagulation using Al-Fe electrodes in reducing contaminant levels of domestic wastewater (COD and TSS). The electrode configuration used in this study was Al-Fe, with a variation of the current strength used was 1 A, 2 A, 3 A. The electrocoagulation process was carried out continuously with a contact time of 12 minutes. The sampling process was replicated at 12 minutes, 17 minutes, 22 minutes, 27 minutes, 32 minutes, 37 minutes and 42 minutes. The instrument used in this study was an electrocoagulation reactor with dimensions of 6 cm x 10 cm x 18 cm with Al and Fe electrode configurations. Treatment of domestic waste using electrocoagulation and filtration technology can remove COD parameters in the Al-Fe electrode configuration with a current of 2 A and sampling at 27 minutes with an efficiency of 95%. The most optimum removal of TSS parameters of 94% was obtained in the Al-Fe electrode configuration with a current of 2 A and taking samples at 37 minutes.

Abstract
Ciletuh Geopark is one of UNESCO’s tourist attractions as one of the Global Geopark located in Sukabumi Regency, West Java, one of the most visited tourist destinations because of its beauty and role in knowledge development. It caused Geopark Ciletuh to have significant growth in facilities and accessibility, which generated land cover change that triggered the critical land. This study aims to analyze the land cover change in Ciletuh Geopark until 2030 to identify essential land. The method used in this study is Cellular Automata-Markov Chain to detect the land cover change and predict its transformation in the future with several driving factors built based on fuzzy logic. The variable contains proximity to the road, the settlement, the coastline, slope, and population density. Land cover map obtained processing Landsat 7 ETM+ and Landsat 8 OLI/TIRS 2010, 2015, and 2020. This study proves that land cover changes are mainly due to housing and facilities’ need to support tourism activities. The conversion from the agricultural area that abandoned becomes shrubs. This research was expected to become a medium that will move the government and local people to make the land used well and still be the sustainable geopark.

Published: January 2021

Abstract
Pharmaceutical wastewater is a critical issue for environmental and human safety due to its resistant characteristic and toxicity. Studies reported that pharmaceutical residue and several drug metabolites have been detected in the aquatic environment and pose a high risk to humans and the ecosystem. Many technologies are ranging from conventional methods, such as activated sludge, anaerobic digestion, and aerobic membrane bioreactors (MBR), to advanced treatment, such as advanced oxidation process (AOP), or integration of more than one method. Integration of Upflow Anaerobic Sludge Blanket (UASB) and constructed wetlands was applied for pharmaceutical wastewater treatment discharged by one of Semarang’s pharmaceutical industry. The performance of UASB and constructed wetlands were evaluated. Up to 75% and 94% of COD removal efficiency was achieved in UASB and constructed wetlands, respectively. An average of 95% of pollutant removal was achieved by the system, indicating the stability and potential of UASB and constructed wetland integration in pharmaceutical wastewater treatment.

Abstract
A rapid catalytic process with low energy requirements gives catalytic ozone the potential to treat industrial textile wastewater in a full-scale application. However, until today, this catalytic ozone technology remains energy-consuming and, as a consequence, expensive. Thus, to overcome the bottleneck related to energy needs, this research aims to design a continuous mode reactor design to treat industrial textile wastewater through catalytic ozone, which integrated solar power plants (PLTS). In this work, a constant mode reactor design combined with an integrated sensor is investigated for industrial textile wastewater. Combining the autonomous and continuous removal of the impurities makes this continuous mode reactor excellent for the treated wastewater on the industrial textile scale.

Abstract
The waters of Ciletuh Bay are one of the waters located in southern Java that interact directly with the Indian Ocean, which is utilized for fishing and tourism activities. Opportunities for utilization of Ciletuh bay waters in the field of fisheries need to be maximized by monitoring the quality of the bay area’s waters. Remote sensing methods can identify and analyse the results of the spectral recording of water with observations of TSS and Chlorophyll-a spreads obtained using the Budhiman algorithm et al. (2004), and the concentration of TSS results from the algorithm Wibowo et al., (1994). Observations were conducted using Citra Landsat-8 in 2019 – 2020. The results of the algorithm’s application obtained the results of TSS concentrations in the waters of Ciletuh Bay have a maximum value of >125 mg/l – 225 mg/l, and a minimum value of 6 mg/l – 15 mg/l. Chlorophyll-a concentration reaches a maximum value of 6 mg/l – 10 mg/l, and a minimum value of 3 mg/l – 5 mg/l. The same distribution pattern is indicated by both parameters: high concentrations in coastal areas and river estuaries and lower in the high seas.

Abstract
This study examines the relationship between SNI ISO Quality Management System (QMS) Standards to Industrial Property Rights in Indonesia using Spearman Correlation Analysis. The focus of research is on the comparison of the correlation coefficient value of quality management system standards: SNI ISO 9001 QMS, SNI ISO 14001 EMS, SNI ISO 22000 FSMS, SNI ISO 13485 MD-QMS, SNI ISO 27001 ISMS, SNI ISO 16949 A-QMS with industrial property rights: patents, simple patents, industrial designs and brands in Indonesia. The test conducted was to see the data relationship between the number of QMS standard certificates to Indonesia’s industrial property rights for seven years, starting from 2009 to 2015. The Spearman Correlation method analyzes the correlation coefficient value on the development of certificate data held in Indonesia. The Spearman correlation test results show that several QMS standards have significant values that have entered the tolerance limit or have gone out of the tolerance limit for industrial property rights. This evidence suggests several quality management system standards able to contribute to the development of innovation in a country, especially Indonesia.

Abstract
Predictive numerical simulation of airflow uniformity in canopy plants could provide a suitable environment for plant growth. A numerical investigation of airflow in a photosynthesis chamber was conducted using the Computational Fluid Dynamics (CFD) model. This research-validated the numerical model with measurements performed in a bare bottom open chamber. The chamber has bottom openings with three exhaust fans on the roof. After model validation, airflow patterns and their uniformity were evaluated in different fan arrangements and doubled air volume rates. The obtained results showed that a more uniform airflow distribution was observed with increasing the fan’s air volume rate (0.0187, 0.0172, and 0.0177 m3s−1), particularly fan in the middle position and diagonally position inside the plant with coefficients of variation of 14.36%, 9.3% and 10%, respectively. Moreover, increasing the fan’s air volume rate and moving the fan positions to the middle and diagonally can significantly help produce uniform air velocity distribution inside the plant.

Published: January 2021

Abstract
A healthy and comfortable habitation in coastal areas is one of the requirements for establishing a modern society in the increasing number of water and air pollutions. On the one hand, high humidity and temperature levels reduce the convenience of settlements in coastal areas. This condition is even worsened in many houses, which are built with poor air circulation. On the other hand, when the house’s windows are opened to allow airflow, many insects such as mosquitoes will enter the room. Mosquitoes are carriers of many diseases in Indonesia, such as dengue fever, malaria, chikungunya and many more. For solving this problem, this paper proposes a solution by designing insect trap of windows connected to a DC high voltage source to exterminate mosquitoes. The source of electricity is obtained from PLN 220 Volt. The voltage from PLN is boosted to reach 3240 Volts. Our prototype has been demonstrated to exterminate a swarm of mosquitoes. When mosquitoes pass through the window trap, they will experience a short circuit, as their body is connected between negative and positive for a short period. The experiment results showed that the applied voltage of 14.6 kV was able to sting mosquitos to death. To prevent its high voltage impact and guarantee the safety of utilization, we provide a safety layer to prevent direct human contact. When it is not in use, the power source can be turned off by using wireless control.

Abstract
This study was conducted to compare between leachate and mixed waste produced electricity as one of the performance parameters of Compost Solid Phase Microbial Fuel Cells (CSMFCs) besides complying with compost requirements. Mixed waste as solid-phase produced from composting has higher potency to obtain electricity than leachate as the liquid phase. Composting of mixed waste was applied in CSMFCs reactor utilizing two anodes placed on leachate chamber at the bottom of the reactor and mixed waste at half of the reactor height and 1 cathode at above of two-third reactor height for electron transfer that its condition was adjusted on more or less 60% of moisture content, seven times of turning frequency, and 50:1 of initial C/N ratio during 23 days process running. The result shows that electrical production in mixed waste is a little more than leachate means that leachate and mixed waste produce the same result on power density as a total value of electricity, but the different of those in electrical production is that mixed waste produces more faster than leachate due to the first exposed electron, the faster-producing electricity.

Abstract
The article presents the results of comparison of the methods of spring tillage for melons in the steppe ilmeni on the Baer hillocks. Agrophysical soil properties, wind resistance, weediness and yield were determined. During the growing of watermelon sprouts, the microaggregate soil structure was wind–unstable. In crops of watermelon cultivated after plowing and deep flat–cutting cultivation, a 2.6–2.8–fold decrease in the number of weeds was observed. The highest yield of Astrakhan was obtained as a result of spring tillage – 42.1 t/ha and deep plane–cutting – 41.3 t/ha. Flat–cutting treatment and the use of the fallow preserved the stubble and contributed to a 5–11–fold reduction in sand transfer under the influence of wind.

Abstract
A number of metal oxide nanopowders (Fe2O3, ZnO, CoFe2O4, ZnFe2O4) were synthesized in an aqueous extract from the leaves of Petroselinum crispum by a biological method. Physicochemical certification of synthesized nanomaterials was carried out. The data on plant cell viability of the reductases enzyme activity (WST test) were obtained against the background of seed treatment with obtained nanopowders in doses from 10–3 to 10–5 M per 4 hours and further short-term action (4, 12 and 24 hours) oxidizing agents (50 μmol H2O2). A following noticeable protective effect was exhibited by CoFe2O4 NPs (pH = 2) and CoFe2O4 (pH=10): cell viability averaged 103, 93, and 92 % respectively. Particles Fe2O3 (84 %) and zinc ferrite ZnFe2O4 both synthesized in an acidic medium (79 %) and alkaline (87 %) had a slightly smaller effect. The remaining nanometals (ZnO, Co3O4) did not have such a strong effect and their reductase activity index was no more than 73 %. The data obtained show the likelihood of using these components in improving the agricultural performance of plants in crop production, improving their growth characteristics and plant productivity.

Abstract
The climatic conditions of the sharply continental climate of the Stavropol Territory influenced the skin of gobies of the Kalmyk, Kazakh white-headed and Hereford breeds. During the year, the skin of animals changed, which contributed to the adaptation of the body to the climatic conditions of the dry zone. These conditions influenced the histology and morphology of the skin of 18-month-old gobies of Kalmyk, Kazakh white-headed and Hereford cattle breeds (6 animals of each breed). The results of the study showed that the greatest thickness of the skin has the Kazakh white-headed bullocks (6544±153 microns). The smallest thickness of skin was in animals of the Hereford breed (5602±140 microns). Kalmyk and Kazakh white-headed bulls had a higher content of fine (downy) hair than Hereford bulls did. The content of sebaceous glands in Kalmyk bulls was 1.5 times higher than that in Hereford bulls and 1.1 times higher than that in the Kazakh white-headed breed. The number of sweat glands in the Hereford breed was 1.4 times higher than that in animals of the Kalmyk breed and 1.3 times higher than that in the Kazakh white-headed. The highest content of type I collagen is detected in the skin of animals of Kalmyk and Kazakh white-headed breeds. The presence of a greater thickness of the dermis in combination with an increased content of sebaceous glands in the skin indicates a higher adaptive capacity of animals of the Kazakh white-headed and Kalmyk breeds of cattle to live in extreme weather conditions and affects the quality of raw materials.

Published: January 2021

Abstract
The analysis of various methods of sowing of grain crops showed that the introduction of indirect sowing in agricultural production contributes to the increase in their productivity. The authors propose justified structural and technological scheme of the sowing system in order to ensure a uniform distribution of seeds over the feeding area to a given depth with their subsequent seeding. The main element of the sowing system is the pneumatic seed feed. Due to the movement in the airflow, the seeds of grain crops at the moment of the concussion against the surface of the distributor have sufficient speed to reach any point on the surface under a V-shaped weep; this contributes to the uniform distribution of seeds across the entire width of the sowing strip.

Abstract
The reaction of large-fruited confectionary sunflower of the LFS variety to different plant density was studied in 2017-2019 in southern slightly humic chernozem in the arid conditions of the steppe zone of Crimea. It was established that the minimum plant stand within the limits of optimal density, which is not more than 30 thousand plants/ha in the climatic conditions during the years of study, allowed obtaining yield within the limits of 1.17–2.38 t/ha with seed oil content of 39.0-46.3 %. With the overcrowding of crops from 30 to 40 thousand pcs/ha, there was a tendency to decrease the indicators of structural elements of crops and the productivity of crops in general. In order to obtain large seeds (102.1–114.0 g), the optimal plant density shall be 20 thousand/ha. The maximum yield of seeds is achieved in crops with plant density of 30 thousand/ha, but the thousand-seed weight under this technology is reduced to 92.4–103.2 g.
