The phenomenon of dancing monkeys is a cultural and traditional art in Indonesia by exploiting primates, especially the Macaca fascicularis or long-tailed macaque species. Law enforcement efforts related to the dancing monkey phenomenon seem biased. Apart from the fact that the long-tailed macaque is one of the unprotected animals, there is also no strict enforcement of existing laws, although they can often be charged with animal health and welfare regulations. This study discusses the urgency of ethics, animal welfare, and health in primates who used dancing monkeys as objects. The method used is a descriptive-qualitative approach based on the relevant scientific literature. There is still very little research related to the dancing monkey phenomenon, both in terms of ethics, animal welfare, and health, the urgency and further recommendations from the results of this study can be used to encourage efforts to prevent the dancing monkey phenomenon in the community by providing suggestions that can be applied to the community such as education, development of informative media, management of educative tourism objects based on wildlife and ecotourism, and participating in volunteering for animal observers or animal welfare in Indonesia.

Extreme event is a short scale rare phenomenon, but it has a quite a serious impact on the various  aspects of life. Studies on the prediction of extreme rainfall that occurred in the  region is needed to minimize the adverse effects of global climate, so the farmers and stakeholders will have a good knowledge about the climate. It is especially extreme  rainfall  events so anticipation  can  be  done early, than  the  production of  rice plant can be maximized and the losses can be minimized. To fulfil these needs, it requires statistical methods that can explain  the extreme  rainfall.  Extreme Value Theory is a statistical  method to identify extreme events. For data rainfall, snow, river flow, or temperature are classified as spacial data being a multivariate data because it’s observed in several locations, and therefore Spatial Extreme Value Method is developed. In the case of Spatial Extreme Value, the approach is often used Copula approach and max-stable process. Copula approach assumes that marginal distribution of extreme values follow a uniform  distribution. Therefore, this study discusses the Spatial modelling of Extreme Value with Copula approach in one of East Java's rice production centres is Ngawi Regency. It is hoped that the method will improve the accuracy of predicting extreme events.

Providing a return line for short-circuit currents or fault currents to a low-resistance ground, grounding system is useful for achieving a uniform potential voltage over a given area of buildings and equipment. Because a large voltage difference can occur if a fault current is forced to ground against a high resistance. Placement of the electrode to be planted is one of the elements to obtain a low grounding resistance value. Grounding resistance measurements, which will serve as a guide for the grounding system design process, are required during the planning stage for certain types of grounding systems. The problem is how the grounding resistance is affected by the buried depth of the rod conductor and the soil type resistance. Therefore, it is very important to conduct research and testing to determine the extent to which these parameters influence. The experimental results of measuring resistance on dry and wet soils are on dry soil 30 cm obtained 98.48 Ω, 60 cm obtained 37.07 Ω, 90 cm obtained 20.52 Ω, 120 cm obtained 19.77 Ω, and for wet soil at a depth of 30 cm obtained 43.34 Ω, 60 cm obtained 22.21 Ω, 90 cm obtained 15.43 Ω, 120 cm obtained 11.66 Ω.  So to get the 5Ω value we make an estimate by adding a depth of 56.603 cm for wet soil and 38.58 cm for dry soil, then the length of the electrode needed is 176.603 cm for wet soil and 158.58 cm for dry soil.

This study was conducted to determine the effect of height in the calculation of box model dispersion modeling. The experimental method was conducted using sample data of sulfur dioxide exhaust emissions produced by the oil and gas industry. The samples were obtained from an oil and gas company that produces sulfur dioxide emissions. There are two types of data obtained, namely hourly emission data and daily emission data generated by the industry with the amount of data obtained for 360 days. The results showed that the mixing height used in the box model formulation affects the results of the calculation. The optimal mixing height obtained from the study was 75 meters where all sample data used in the calculation showed that there were only 3.5% or 11 samples that did not meet the ambient air quality standards. The results also showed that the higher the mixing height used, the lower the emission of sulfur dioxide emission dispersion modeling calculation results. While calculations with lower mixing height will produce results that are inversely proportional to the concentration of sulfur dioxide emissions, the concentration of sulfur dioxide emissions produced will be higher. Therefore, sulfur dioxide dispersion modeling using a box model can be an alternative in determining the concentration of sulfur dioxide emissions produced.

Heavy metals are pollutant parameters that contain high toxicity and are dangerous which can accumulate in the tissues of living things. One of the heavy metals contained in wastewater is lead (Pb). This metal is included in the extremely toxic category which can cause health problems. One way to treat waste containing the heavy metal Pb is by bioremediation using microalgae (phycoremediation). In this study, phycoremediation used the microalgae Chlorella vulgaris and Nannochloropsis oculata, as well as a consortium of both. This study aims to determine the ability of each microalga and the consortium of the two microalgae in removing lead heavy metals. The phycoremediation potential was measured based on the ratio of microalgae varied (100:0, 50:50, and 0:100) and the concentration of Pb waste (1, 5, and 10 mg/L) within 14 days on a batch scale. The results showed that the microalgae Chlorella vulgaris in reactor 10B (100% Chlorella vulgaris, 0% Nannochloropsis oculata) was able to remove 85.0% from a concentration of 10 mg/L to 1,5 mg/L.
