<![CDATA[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.]]>

<![CDATA[Natural fiber reinforced composites are widely applied to equipment with materials that have a combination of two basic properties, namely strength and lightness. This study aims to determine the optimum ability of kenaf stem fiber and tobacco stem fiber which contain relatively high cellulose to be used as soundproofing materials and also to utilize tobacco stems which were originally considered as agricultural waste to become a more useful raw material. Comparison of stem fiber ratio kenaf and tobacco stem fiber 100:0, 60:40, 50:50, 40:60, and 0:100. From the research results obtained, the composite exhaust produces the smallest sound, namely 81.6 dBA at a fiber ratio variation of 60:40 at 1500 RPM and produces the biggest sound, namely 99.1 dBA at a fiber ratio variation of 0:100 at RPM 3500. Results it can be said that the damping of the composite exhaust is quite good because it is not too far from the quality standard threshold of 83 dBA. The ability of kenaf stem fiber to reduce noise is better than that of tobacco stem fiber because the cellulose content in kenaf stem fiber (by 50%) is higher than that of tobacco stem fiber (by 37%).]]>

<![CDATA[The dc output voltage of the solar cell is regulated due to changes in the intensity of sunlight shining on the surface of the solar cell, so that in the treatment of storing the dc output voltage of the solar cell to an external electrical load energy saver becomes unstable. Testing the occurrence of regulation of the dc output voltage of the solar cell expressed as the Vo(cell) parameter is carried out by changing the distance of the white light intensity irradiation from the LED lamp to the surface of the solar cell. The research method of adding a dc-dc converter device to the output part of the solar cell produces a stable dc output voltage parameter from the dc-dc converter device. The results of the research on charging energy storage on HP charge batteries using (1) the output voltage supply without the dc-dc converter parameter Vo(cell) obtained the results of charging the electrical energy load of the hp charge battery at Wb1(bat.) = 1.408 watt.hours and ( 2) The use of the supply voltage output Vo(conv.) from the dc-dc converter results in charging the electrical energy load for charging the battery charge hp reaching Wb2(bat.) = 1.426 watt.hours. There is a difference in the length of time it takes for the results of electrical energy to fill the cell phone charge battery using an output voltage source supply originating from a dc-dc converter regulator compared to an output voltage source without using a dc-dc converter regulator.]]>

<![CDATA[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.]]>

<![CDATA[Kuwe (Caranx sp.) is a captured fishery commodity in the Sangihe Islands. The abundant catch of fish makes it difficult for fishermen to market because the local market in the Sangihe Islands cannot absorb it, and there is no cold storage with a large capacity to maintain the quality of fish. One of the ways to increase the durability is if the production of kuwe fish is abundant, namely by the dry salting method. The dry salting technique is relatively straightforward, so the community can apply it. This study aimed to observe the sensory characteristics and moisture content of salted kuwe fish products using the dry salting method. The research method was cleaning and fileting the kuwe fish meat, then dry salting with a salt concentration of 10%, 15%, and 20%, and drying in the sun. The results showed that the sensory test for salted fish appearance, aroma, taste, and texture was best at 15% salt concentration, with panelist values of 8.65, 8.20, 7.95, and 8.50 (respectively). The water content of salted fish at a salt concentration of 15% is 28.20%. The sensory characteristics and water content of salted kuwe fish wih salt concentration of 15% have complied with SNI 8273:2016, namely a minimum of 7 and a maximum of 40%.]]>
