Manado Bay is a water body that protrudes in the area of Manado City where the condition of this region is likely to have a tsunami threat.
Manado Bay is home to several rivers such as Tondano River has geological history of both land and sea. There are several active faults, such as in the sea, subduction of sub plate in north of island, Mayu mountain plate, and Sangihe plate east of North Sulawesi. The purpose of this study is divided into two parts General purpose is to describe GIS-based disaster mitigation that can be done to minimize disaster risk if Tsunami disaster occurs in coastal area of Manado Bay, while special purpose consists of 3 parts, namely 1.
Mapping of zone- Tsunami vulnerability zone of Manado Bay; 2. Mapping the distance and time of the scenario of the Manado Bay Tsunami evacuation route; 3. Mapping of the number of buildings and roads exposed to the Manado Bay Tsunami. Data collection techniques use secondary data collection techniques. Secondary data comes from related institutions or institutions, libraries, or individual archives. The data collection is also continued by direct observation. Direct observation is meant by direct observation by using checklist for secondary data adjustment and then determination of coordinate point with Global Position System GPS at some tsunami location.
EFFECT OF BLADE FIN ON THE POWER GENERATED BY A SAVONIUS ROTOR VERTICAL AXIS WIND TURBINE TYPE L Deny Prabowo, Danar Susilo Wijayanto, Indah Widiastuti. Sebelas Maret University. Increasing of electricity energy consumption sourced from fossils over time continues to grow. The fossil energy reserves will be faster exhausted than expected because of the increasing trend of fossil energy production. Wind as an environmentally friendly renewable energy source can be an alternative solution reduce the consumption of fossil energy.
1 m and a rotor height of 1. This research used a savonius wind turbine type L with a rotor diameter of 1. The material used for the blade is aluminum plate. Generator using a type PMG 200 Watt with pulley transmition system 1 4. The method used is the experimental method by varying the addition of the fin on blade and the wind speed. Variables taken in this research are wind speed, variation of attaching fin, and electric power generated by wind turbine.
Variations of additioning fin are without fin, 1 fin, 2 fin, 3 fin, 4 fin. Testing tools using anemometer, tachometer, ampere and digital voltmeter. The highest wind frequency occurs at wind speed interval 2. The average wind speed during the test was 2. 8 m s with a maximum wind speed of 5 m s. The results of the research was found that the blade fin affect the electric power generated but the number of fin in the blade is not linearly result in increasing ot the electric power.
This research aims to analyze the influence of blade fin on the power generated by a savonius wind turbine type L with variation of wind speed. The increasing number of fin results in lower power generated compared by the with one fin. The variation of addition 1 fin generates the largest electric power that is 10. 66 watt at wind speed of 4. 5 m s with 240 rpm rotation of generator. The lowest cut in speed is 2 m s achieved the addition of 4 fin on the blade. By knowing the shape of the rotor, the dimensions of the rotor, the addition of fin, transmission and generator used can be found alternatives to increase the electrical power generated by savonius wind turbine.

Parental defense of offspring is an important thing during a predator attack in many species. A higher level of defense will save the offspring but in the other hand it also exposes a higher risk for parent.
In this article, the authors try to construct the model for parental defense in prey population. The model based on stage structured dynamical model which assumed that the offspring are entirely dependent on parental care for survival. A contact between parent and predator describe as a distance, not a direct bodily iq option imposto de renda. The dynamic and stability analysis are done here to predict the optimal level of defense.
Furthermore, the simulation are shown to understand the behavior of prey population with a certain level of parental defense. The simulation showed that parental defense is increase during breeding and nesting season. A Prospective Method to Increase Oil Recovery in Waxy-Shallow Reservoir Fiki Hidayat, Muslim Abdurrahman. Universitas Islam Riau.
Waxy oil has been the main characteristics of The X field. Initial screening criteria studies indicated that cyclic steam stimulation CCS would be the optimum option because favorable reservoir condition. Based on this method we would like to know how much oil gain and the effect of steam for the stimulated and surrounding well. The injection of steam was done for 7 days followed by 14 days of soaking period. 39,000 liter of Marine fuel oil was used to generate steam for stimulation with an average produce steam quality about 80.
Average of 255 MMBTU of steam was injected each day with total steam injected was about 1. The oil production was increased four times from 5 bopd into 21 bopd. Proper well candidate and high permeability are the some reason for successfully this method in order to increase oil production. Additional heat from steam reduced the damage near wellbore due to wax deposition.
This is verify by increasing productivity index from 3 bbl psi to 4 bbl psi. From results and observation data, this method can be a platform for typical shallow depth reservoir with high paraffinic content especially other reservoir in Sihapas formation.
