<strong>Mercury Content in Commercial Fishes of Bantul Areas and Yogyakarta. </strong> Mercury Content in Commercial Fishes of Bantul Areas and Yogyakarta Fish is an important energy source for the body and has many functions for human health. Hence, the fish are highly favored for consumption by the public. However, the fish has the ability to accumulate heavy metals. One type of dangerous heavy metals and can accumulate in fish is mercury because it has high toxicity at low concentrations. The presence of contaminants from anthropogenic activities that are not processed previously, makes the fish a potential hoarder for heavy metals. This study examined the concentration of mercury in freshwater fish and saltwater fish consumed by the people of Bantul areas and Yogyakarta. Fish samples were collected on 29–30 August 2015 from Prawirotaman Market, supermarket, Embankment on the River Code, and purchased from fishermen in Depok Beach. Analysis of mercury concentrations in fish was done using mercury analyzer NIC MA-3000. The results indicated that the fish with the eating habits of benthivore and planktivore accumulated higher mercury than omninore and carnivore fish. The concentration of mercury in the fish examined does not exceed the threshold of the WHO standard, BPOM-RI, and European Union standards. However, the people need to be alert on mercury bioaccumulative properties, especially when consuming the fish having accumulated mercury continuously for a long time.

There are many ways of diagnosis in Ayurveda but one of them is Nidan panchak . Nidan panchak is the one of the most important method to diagnose disease, its causes and prognosis. Nidan panchak is consist of five sub types which are Nidan  (causes), Purvroop  (symptoms), Roop (signs), Upshaya  (examination methods) and Samprati  (pathogensis). The diagnosis of disease in Ayurveda is done by Prakriti of the patient. Prakriti of the patient depends on the Dosha  (Vata, Pitta, Kapha) Diagnosis of disease depends on Tridoshas which are Vata, Pitta, Kapha. By the imbalance of these Tridoshas disease occurs in the body. These imbalances in the body Doshas is due to lifestyle, diet and eating habits of the people. Diagnosis is the important component for the treatment of disease. In Ayurveda there are many techniques other than Nidan panchak which are used for the diagnosis of the disease they are Naadi pareeksha, Dashvidh pareeksha, Asthvidh pareeksha but in this article importance of Nidan panchak is explained.

Homecoming activities that occur each approaching Eid certainly make travelers feel exhausted on the way to their hometown. So with that it requires activities that help travelers. In this case we provide a place to rest for travelers and provide free massage for travelers. Massage comes from the French word "masser" which means rubbing or from the Arabic word "mash" which means to press it gently or from the Greek word "massien" which means to massage or wrap. With the provision of massage it is expected that travelers can relax and make the body fit again. Based on the above problems, we need a place of rest for travelers who drive motorized vehicles and volunteers who are able to reduce driver fatigue by giving free massage to the travelers. With this done, it is expected that the smoothness and safety of motorists who make homecoming in 2019 can be maintained until they are in their respective hometowns. The target of this community service activity is travelers in 2019 who pass through Banyuwangi City. The preparatory stages include location survey, after that coordinate with the campus to hold campus room loan licensing as a place of rest and massage place for the homecomers. In addition, we are socializing to the public that there will be a free massage at Campus C, Uniba Banyuwangi. Providing all the facilities of massages, such as mattresses, olive oil and towels. The implementation phase is carried out May 18-19, 2019. The homecomers are recorded by filling in attendance and biodata. Travelers come into the room to rest and are given massage treatment. Based on the results of community service activities that have been carried out, the people who have been going home in 2019 are happy and are greatly helped by the location of free rest and massage. The resting place is very helpful for travelers to see a long time in travel and the long distance traveled by the travelers. For free massage activities also make travelers feel more comfortable and more fit to continue their homecoming journey to their hometown.

Nanotechnology is currently an upward trend in diverse fields, and therefore, its application will be reviewed in this paper. One of the nanotechnologies which can be used in environmental remediation is carbon nanotube (CNT). Its excellent mechanical and chemical properties allow it to have better achievement in remediating a wide range of organic and inorganic pollutants. CNT can be categorized into two types: single-walled carbon nanotube and multi-walled carbon nanotube. Due to urbanization, various types of pollutants have been released into the environment in great amounts. For instance, estrogen is the hormone generated and released from animals and humans. However, the overconcentration of estrogen affects the physiology of biological life. Besides, pesticides are frequently used by farmers to increase the fertility of the land for agricultural purposes, while heavy metals are commonly found during anthropogenic activities. Long-term absorption of heavy metals into the body tissues will accumulate toxic effects, leading to body system dysfunction. Hence, CNT technologies, including adsorption, membrane filtration, disinfection, hybrid catalysis, and sensing and monitoring, can be applied to remediate these pollutants. However, the application of nanotechnology and CNT faces several challenges, such as production costs, toxicity, ecological risks, and public acceptance. Application of CNT also has pros and cons, such that the lightweight of the CNT allows them to replace metallic wires, but dealing with nano-sized components makes it challenging.

Stunting in general is a failure condition growth against children, caused by malnutrition in a long time. Milk has a good nutritional content and required by the body for the process of growth. In Indonesia, there are still many toddlers and children who do not consume milk that can cause stunting. It is influenced by the high milk prices in the market. To overcome the problem, soy milk can be a solution, because it contains a substance which is equivalent to cow's milk. The village Kutagandok is one of the villages stunting, which is located in Karawang District. Countermeasures carried out of the village to reduce stunting is the provision of soy milk to toddlers and kids. The process of the production of soy milk is made by the people of the village Kutagandok. But the thing is, there are still some obstacles in the production of, namely the limited human resources (HR) for the separation process soy beans with the skin's epidermis. So then it takes a HR more to make the production time to be shorter. In addition, the length of time filtering soy milk which resulted in easy casserole. The purpose of this service is to help the village of reducing stunting, by way of automation peeler soybeans from the epidermis and the filter tool to separate the soy milk with the dregs. Initially the process of the production of soy milk is used in a conventional manner. Furthermore, through this service uses the peeler semi-conventional. With the filter tool, then the time the production process is faster and quality is better.

Soil microbial environment have been affected by different concentration heavy metals Cd (HM) and tylosin (TYL) and combination of TYL and HM interactions. Degradation of TYL was caused certain inhibition due to the addition of HM. The germination index of seed had been inhibited owing to the toxic effects of HM and TYL, but we found that the low concentrations of HM (4 mg/kg), the germination index higher than the soil which unadded HM and TYL in it. The soil enzyme activity was significantly suppressed by the addition of HM and TYL. Actinomycete was inhibited by high concentrations of HM for a long time. The studies demonstrated that the pollution of the soil micro-environment has been serious than only add HM or TYL in the soil.

Background: Fish is a source of nutrition; however, toxic substances and heavy metals may enter human body due to consuming contaminated fish. The aim of this study was to investigate the levels of heavy metals and DDTs in Liza parsia, a fish species, and assess the health risk of the contaminants in the fish samples. Methods: The extracted fish lipid was added with n-hexane and H2SO4 and was kept for long time. The upper organic part was collected for the analysis of DDTs by gas chromatography equipped with electron capture detector. The fish samples were homogenized by wet digestion method, and the heavy metal contents were analyzed, using an atomic absorption spectrophotometer. The health risks of the fish samples were assessed based on target hazard quotient and target cancer risk. Results: The pesticide contents of DDT, DDD, DDE and DDTs in the fish samples were 0.0414, 0.000253, 0.015 and 0.0567ng/g, respectively. Also, the mean concentrations of Mn, Fe, Cu and Zn were 35.42±10.05, 318.75±242.45, 41.67±4.78 and 281.25±5.42 mg/kg, respectively. Of note, the Cd and Pb contents were below the detection limits. The concentrations of other heavy metals were above the reference limits, which can cause various disease processes. Conclusion: The contents of four heavy metals and DDTs in the samples were above the limits. The main sources of these substances are likely due to human anthropogenic activities. Fish and other edible aquatic animals should be monitored regularly and the heavy metal levels be determined and declared to the public.

The paper presents the results of comprehensive studies on the problem of formation of a deposit of heavy metals in plant communities of the West Siberian Arctic and Subarctic. The regularities of the concentration and redistribution of heavy metals in the soil-plant system have been revealed. Excessive accumulation of heavy metals by different plant species is limited by the selectivity of root absorption in relation to certain elements, and therefore it is important to calculate the coefficient of biological absorption. The interrelation between the intensity of recreational loading and change in the nature, grass cover structure.Among the identified pollutants that accumulate by plants identified a group of heavy metals and microelements (Pb, Sr, Cu, Zn, Ni ). It is shown that the linear dependence of the accumulation of metals in the system “soil-plant” is observed only in the range of low concentrations of pollutants in the ground growing. With high concentrations the reverse dependence occurs. Formulated, justified and tested methodical approaches to preparation of complex long-time observations of the natural ecosystems.

The role and significance of microorganisms in environmental recycling activities marks geomicrobiology one of the essential branches within the environmental biotechnology field. Naturally occurring microbes also play geo-active roles in rocks, leading to biomineralization or biomobilization of minerals and metals. Heavy metals, such as chromium (Cr), are essential micronutrients at very low concentrations, but are very toxic at higher concentrations. Generally, heavy metals are leached to the environment through natural processes or anthropogenic activities such as industrial processes, leading to pollution with serious consequences. The presence of potentially toxic heavy metals, including Cr, in soils does not necessarily result in toxicity because not all forms of metals are toxic. Microbial interaction with Cr by different mechanisms leads to its oxidation or reduction, where its toxicity could be increased or decreased. Chromite contains both Cr(III) and Fe(II) and microbial utilization of Fe(II)- Fe(III) conversion or Cr (III) - Cr (VI) could lead to the break-down of this mineral. Therefore, the extraction of chromium from its mineral as Cr (III) form increases the possibility of its oxidation and conversion to the more toxic form (Cr (VI)), either biologically or geochemically. Cr (VI) is quite toxic to plants, animals and microbes, thus its levels in the environment need to be studied and controlled properly. Several bacterial and fungal isolates showed high tolerance and resistance to toxic Cr species and they also demonstrated transformation to less toxic form Cr (III), and precipitation. The current review highlights toxicity issues associated with Cr species and environmental friendly bioremediation mediated by microorganisms.
