The purpose of this study was to determine the nutrient content of bokashi fertilizers that matched the SNI compost quality standards and the best bokashi and chrysanthemum mixture dosages and the effect of increasing the best chemical status on post-coal mine soil. This research was conducted for two 2 months. The land for this research was taken from post-coal mine land in the Loa Bakung area, Samarinda. The place for conducting research is carried out on Jl. Jakarta Blok BN No 36. Loa Bakung, Samarinda. The method used in this study is descriptive and comparative. This research has 2 stages, namely the first stage of making bokashi kiapu and krinyu mixture and the second stage of the incubation process of post-coal mine soil with a treatment dose that is soil without bokashi, soil with a dose of bokashi 17.5 g polybags, 20 g polybags and 22.5 g polybags, each repeated 3 times. Then analyzed at the Soil Science Laboratory, Mulawarman University Faculty of Agriculture, with parameters pH, C/N ratio, C-organic, N, P, K. Bokashi analysis data based on 2004 SNI Compost Quality Standards and soil analysis data based on soil chemical review status which was developed by the Bogor Soil Research Center in 2009. The results of this study showed that the bokashi mixture of kiapu and krinyu had an effect on increasing soil chemical properties in post-coal mine land, the status of bokashi according to SNI, 22.5% organic C had not matched the quality standard, pH 8.87 not yet according to quality standards, N 1.86% according to quality standards, C/N 12.11 according to quality standards, P 0.98 ppm according to quality standards, and K 2.11 ppm according to quality standards. The best application is at a dose of 22.5 g polybags with a rise at week 4, namely pH 4.94 with acidic status, organic C 2.71% with moderate status, N 0.16% with low status, C/N ratio 16 , 08 with high status, P 31.85 ppm with high status, and K 120.41 ppm with very high status.

One of the way to use green tea factory waste (tea fluff) as a source of plant nutrients is in the form of compost. The aim of this research was to get the appropriate composition of composting of green tea factory waste using a combination of EM4 and cow manure and composted for 5 weeks (35 days). This research was designed in randomized block with 6 treatments and four replications. Compositions of tea fluff and manure compost consisted of: P1 = Control; P2 = Tea Fluff + cow manure (1: 1); P3 = Tea Fluff + cow manure (1: 2); P4 = Tea Fluff + cow manure (1: 3); P5 = Tea Fluff + cow manure (2: 1); and P6 = Tea Fluff + cow manure (3: 1). Data related to composting process such as physical quality (color, texture, and odor) and chemical analysis (pH, C-organic, N-total and C/N ratio) were taken. Based on the results of daily temperature and pH fluctuations, composting proces ran normally. Based on the results of chemical analysis, the parameters of pH, organic C and N-total compost showed significant differences. Within 5 weeks, all compost parameters that have been analyzed chemically and the results has fulfilled the quality standards according SNI 19-7030-2004 standard. Combination of tea fluff:cow manure (3: 1) showed the highest C-organic and N-total results among all treatments.

Control of quality standards is very important role in ensuring corn on the market. Corn seed quality standards are determined from the results of  classification process applied. So far, evaluation process of classification of corn seeds quality is still done manually which takes a long time and the quality of product is'nt evenly distributed. So, we need a tool to determine corn seeds quality to improve its quality. This study conducted color readings of corn seeds using  TCS230 color sensors and sorting  diameter of corn seeds using a small, medium, and large diameter sieve machine. The method for classifying quality standard of corn seed color uses fuzzy logic. The test was carried out by taking data from 3 TCS230 color sensors on each diameter of the sieve machine for corn seeds types used are BISI-2 and BIMA-19. The sensor accuracy is known by comparing data from sensor with data from Color Grab application. The reading results of BISI-2 on the color sensor-1 shows an accuracy rate of 0.3%, the color sensor-2 shows an accuracy rate of 0.72%, and the color sensor-3 shows an accuracy rate of 1.76%. For BIMA-19 corn seeds, the reading on color sensor-1 shows an accuracy of 1.11%, the color sensor-2 shows an accuracy of 24.6%, the color sensor-3 shows an accuracy of 1.10%. The results of fuzzy testing on BISI-2 and BIMA-19 showed that quality standard of maize seeds was good at medium and large diameters, while those on small diameters showed poor quality standards.

This paper explained heavy metals and chemical properties from the Cisadane River in Tangerang City. A survey method was used to determine the place for sampling the test material. Water measurement is carried out in situ and laboratory tests. Data retrieval was done by purposive sampling determining three observation stations, namely in the Taman Gajah Tunggal park area (station1), Babakan Cikokol residential area (station 2), and Karawaci paper mill area (station 3). The analysis was carried out exactly using analysis. Namely, analysis carried out in the laboratory. The parameters observed were COD, phosphate, DO, BOD, pH. Results of this study informed the water quality in the Cisadane City river did not meet Class II Water Quality Standards based on Government Regulation Number 82, the year 2001. The COD content only meets class II water quality standards at stations 1 and 3. BOD and phosphate content is high and exceeds class II water quality standards. Heavy metal content still meets the water quality standard threshold with a value of Cd less than 0.01 mg/L, Cu less than 0.02 mg/L, Pb less than 0.03mg/L, and Cr less than 0.05mg/L. Zn content exceeds the water quality standard threshold at station three and meets water quality standards at stations 1 and 2 with a value of less than 0.05mg/L.

This study focused on verifying whether the emission of air pollutants in São Paulo increases the costs and number of hospitalizations for respiratory diseases in Brazil. Data on pollutant emissions, hospitalizations, and hospital costs were collected from 2008 to 2017 and correlated with air quality standards. The results showed that the concentration of particulate matter increased each year during the study period and was highly correlated with hospitalizations due to respiratory diseases. Ozone (O3) was within the quality standard throughout the study period but registered an increase in the mean and a positive correlation with hospitalizations due to respiratory diseases. The carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen dioxide (NO2) levels were within the quality standards throughout the study period with a decrease in the last years studied, but showed a positive correlation with hospitalizations due to respiratory diseases. The pollutant emissions and hospitalizations due to respiratory diseases had an inverse relationship with the monthly rainfall curve for São Paulo, which indicates that rainfall tended to reduce pollutant emissions and consequently hospitalizations due to inhalation of these pollutants. Because costs are directly associated with hospitalizations, both increased during the study period—302,000 hospitalizations at an average cost of 368 USD resulted in a total cost of 111 million USD. To reduce these costs, Brazil should implement stricter policies to improve the air quality of its major cities and develop a viable alternative to diesel vehicles.
