The perumnas gunung area is one of the areas in the Larangan sub-district, Harjamukti Subdistrict, Cirebon City, whose drainage system greatly disturbs the activities of the population in Cirebon City because when heavy rain causes the high volume of water in the drainage so that it comes out to the highway and is very disturbing it can also cause congestion.To solve the problem of inundation and flooding, it requires maximum rainfall data, population density data and hydraulic data from direct observation at the research location. From the rainfall data, the intensity of the rainfall is calculated, then the standard deviation is calculated to get the return period value using the Gumble formula. From the calculation of the Return Period, the calculation of the flood discharge is carried out using a rational method and calculating the discharge of the existing channel. Calculation of the capacity of the existing channel discharge is carried out by calculating the discharge of rainwater and discharge of household wastewater.From the calculation of Hydrology and Hydraulics, the value of Rainfall Intensity is 46.632 mm / day, the overall channel discharge = 0.603 m3 / s, the calculation of the total discharge from household wastewater and rainwater discharge for the 2-year return period is 0.0076 m3 / s. . From the calculation results, the authors conclude that the dimensions of the existing canal can still accommodate the flow of rainwater and household wastewater. The solution to overcome flood inundation on Jalan Ciremai Raya, it is necessary to normalize the drainage channel so that the drainage channel can function properly.

Fire fighter performance can be represented by the speed of handling the fire case, where greatly influenced by the travel speed of the fire trucks to the fire location. This study aims to determine the fastest route for fire trucks in Cirebon City based on the travel distance, time, congestion and land use. The method used in this study is by applying the Geographic Information System (GIS) model in identifying several variables that affect the travel speed of fire trucks. In this study, several alternative routes were determined from the fire station (Harjamukti fire station and Bima fire station) to the location of fire (Harjamukti Market) and then calculated the travel time on each alternative route by considering travel distance, time, congestion and land use. The results showed that the fastest travel time for fire trucks in Cirebon City was largely influenced by the travel distance. However, in conditions of high traffic flow, a route with a longer distance but does not cross a congested road segment can produce a faster travel time when compared to a shorter route but crosses congested roads. The fastest route from the Bima fire station to Harjamukti market is route 1 (2,854 m) in the morning, route 3 (3,019 m) in the afternoon and evening. Meanwhile, the fastest route from the Harjamukti fire station to Harjamukti Market is Route 1 (2,069 m) in the morning, afternoon and evening because it has the shortest distance.

Well Completion Test is a testing activity undertaken to determine the depth of production zone and feed center depth as well as to calculate the estimated production capacity of a well. Well completion tests are performed on wells that have just been drilled by exploring the depth of the well, measuring pressure and temperature, water loss test and gross permeability test. As a result of exploring the RL well, the tool was placed at a depth of 2000 meters. Injectivity is done at different pump rates, pressure and liquid faces. The gross permeability test results obtained an injection of 202.22 lpm/ksc, an average specific capacity of 5.028 lpm/meter, transmissivity of 0.1208955 darcymeter and skin factor 3.33381. Next calculate the production estimation using the injection that has been converted and plot to the graph then obtained the result of the estimated potential production of a well that is 6,3 MW. After a well has completed a well completion test, the next step is to test the production for more accurate results, because of the well completion test itself the accuracy is only about 50% only, therefore the production test needs to be done for the results which in getting more accurate.

The development of cities in Indonesia is marked by the high number of commuters (commuters) who travel between the main city and the surrounding city or district (hinterland) or between regions within a city due to an increase in population, population activities, types of services, and the relative functioning of the economy national and regional level of a country.. Â Â Â Â Â Â Â Transportation problems and challenges are multi-dimensional between transportation systems and urban systems, both operational, management and policy aspects. Urban transport policies that care about sustainable development in developing countries are very complex, but can be studied especially in the public transportation system because it is more possible when compared to private transport at this time. Â Â Â Â Â Â Â In Indonesia, the number of motorized vehicles is increasing every year. The addition of that number in 2012 reached 10,036 million units, resulting in the population recorded in the Indonesian National Police increased 12% to 94.292 million units compared to only 84.19 million in 2011 (Kurniawan, 2013). Based on data from the National Police also stated that in 2012 there were 109,038 accident cases with 27,441 people died. Different data from the Coordinating Ministry for Economic Affairs and People's Welfare of the Republic of Indonesia states that motorcycle rider accidents have reached 120,226 times or 72% of all traffic accidents in a year. Most accident cases occur in people with lower middle economic level as motorcycle and public transportation users (State Intelligence Agency, 2013). Â Â Â Â Â Â Â As released by WHO (World Health Organization), of all accidents that occur on the highway, the human error factor (human error) has the highest contribution, reaching between 80-90 percent compared to the factor of vehicle vehicle improperities ranging from 5-10 percent, as well as due to damage to road infrastructure by 10-20 percent (DG Hubdat, 2010). Vehicle facilities that often occur are less than 1 millimeter of tire grooves resulting in vehicle skid or tire breaks, brakes failing, metal fatigue resulting in broken vehicle parts, worn equipment not replaced, and various other causes. This is very much related to the technology used and the care done to the vehicle. One of the government's efforts to improve road safety is through safety vehicle action programs such as compliance with vehicle operations, organizing periodic and type test repair procedures, handling overloading, vehicle scrapping, and developing motor vehicle design that aims to improve vehicle safety technology (DG Hubdat, 2013).

印度尼西亚城市发展的特点是，由于人口、人口活动、服务类型以及国家和地区经济水平的增加，在主要城市和周边城市或地区(腹地)之间或城市内部区域之间旅行的大量通勤者(通勤者)。Â Â Â Â Â Â Â交通问题和挑战在交通系统和城市系统之间是多维的，包括运营、管理和政策方面。在发展中国家，关注可持续发展的城市交通政策非常复杂，但可以特别在公共交通系统中进行研究，因为与目前的私人交通相比，公共交通系统更有可能。Â Â Â Â Â Â Â在印度尼西亚，机动车辆的数量每年都在增加。2012年这一数字的增加达到了10,036万个单位，导致印度尼西亚国家警察记录的人口增加了12%，达到9,429.2万个单位，而2011年只有8,419万个(Kurniawan, 2013)。根据国家警察的数据，2012年发生了109038起事故，27441人死亡。来自印度尼西亚共和国经济事务和人民福利协调部的不同数据表明，摩托车骑手事故在一年内达到120,226次，占所有交通事故的72%。大多数事故发生在摩托车和公共交通使用者等中等经济水平较低的人群中(国家情报局，2013)。Â Â Â Â Â Â Â正如世卫组织(世界卫生组织)发布的，在高速公路上发生的所有事故中，人为错误因素(人为错误)的贡献最大，达到80- 90%，而车辆车辆不规范的因素为5- 10%，道路基础设施损坏的因素为10- 20% (DG Hubdat, 2010年)。经常发生的车辆设施是轮胎凹槽小于1毫米导致车辆打滑或轮胎破裂，刹车失灵，金属疲劳导致车辆零件损坏，设备磨损不更换，以及各种其他原因。这与所使用的技术和对车辆的护理密切相关。政府改善道路安全的努力之一是通过安全车辆行动计划，如遵守车辆操作，组织定期和型式试验修理程序，处理超载，车辆报废，以及开发旨在提高车辆安全技术的机动车设计(DG Hubdat, 2013)。关键词:运输性能，用户满意度。

Urban transport policies that care about sustainable development in developing countries are very complex, but can be studied especially in the public transportation system because it is more possible when compared to private transport at this time. Â Â Â Â Â Â Â In Indonesia, the number of motorized vehicles is increasing every year. The addition of that number in 2012 reached 10,036 million units, resulting in the population recorded in the Indonesian National Police increased 12% to 94.292 million units compared to only 84.19 million in 2011 (Kurniawan, 2013). Based on data from the National Police also stated that in 2012 there were 109,038 accident cases with 27,441 people died. Different data from the Coordinating Ministry for Economic Affairs and People's Welfare of the Republic of Indonesia states that motorcycle rider accidents have reached 120,226 times or 72% of all traffic accidents in a year. Most accident cases occur in people with lower middle economic level as motorcycle and public transportation users (State Intelligence Agency, 2013). Â Â Â Â Â Â Â As released by WHO (World Health Organization), of all accidents that occur on the highway, the human error factor (human error) has the highest contribution, reaching between 80-90 percent compared to the factor of vehicle vehicle improperities ranging from 5-10 percent, as well as due to damage to road infrastructure by 10-20 percent (DG Hubdat, 2010). Vehicle facilities that often occur are less than 1 millimeter of tire grooves resulting in vehicle skid or tire breaks, brakes failing, metal fatigue resulting in broken vehicle parts, worn equipment not replaced, and various other causes. This is very much related to the technology used and the care done to the vehicle. One of the government's efforts to improve road safety is through safety vehicle action programs such as compliance with vehicle operations, organizing periodic and type test repair procedures, handling overloading, vehicle scrapping, and developing motor vehicle design that aims to improve vehicle safety technology (DG Hubdat, 2013).

ABSTARCT Media salinity is a masking factor that plays an important role in controlling the process of shrimp molting and osmoregulation. Both of them are ecophysiological factors for shrimp life, so it is necessary to know the optimum level or range of media salinity for each phase of the molting phase changes in the stage and osmoregulation phase. This study was conducted to examine the molting frequency of adult L. vannamei which was ablated and cultivated at various levels of salinity. This research was carried out for 60 days. This study uses experimental laboratory methods with a systematic randomized design (RAS) with 4 treatments and 3 replications in each treatment. The treatments tested were salinity with S1 treatments (10 ppt, 289.20 mOsm / l postmolt H2O isosmotic), S2 (15 ppt, 432.80 mOsm / l H2O initial intermolt isosmotic), S3 (25 ± 1 ppt, 725, 15 mOsm / l H2O isosmotic final intermolt) and S4 (29 ± 1 ppt, 820.10 mOsm / l H2O isosmotic molt). Data were analyzed with ANOVA. Meanwhile, the difference in effect between treatments was obtained through Duncan's multiple area test. ANOVA results showed that various levels of isoosmotic media salinity at various molting phases had an influence (p <0.05) on molting frequency. The best value of molting frequency was in the S4 treatment (29 ± 1 ppt) (close to isoosmotic molt) 10 times. In the maintenance of L. vannamei which is affixed, it should pay attention to the needs of isoosmotic media, namely media with a salinity of 25 ± 1-29 ± 1 ppt (final intermolt isoosmotic range / premolt to molt). the difference in effect between treatments was obtained through Duncan's multiple region test. ANOVA results showed that various levels of isoosmotic media salinity at various molting phases had an influence (p <0.05) on molting frequency. The best value of molting frequency is in the treatment of S4 (29 ± 1 ppt) (close to isoosmotic molt) 10 times. In the maintenance of L. vannamei which is affixed, it is better to pay attention to the needs of isoosmotic media, ie media with a salinity of 25 ± 1-29 ± 1 ppt (final intermolt isoosmotic range / premolt to molt). the difference in effect between treatments was obtained through Duncan's multiple region test.

Carbon Steel 1018 is a low carbon steel having a carbon content (C) of 0.14-0.20% (<0.30% C). Low carbon steel is commercially known as mild steel. Corrosion is one way to prevent corrosion caused by the environment. Corrosion inhibitor are taken between the Crude Corrosion Inhibitor and Gas Corrosion inhibitor on Carbon Steel 1018 using the polarization method. Corrosion inhibitors work by making passive layers in the form of thin films or films on the surface of the material used as a barrier between metals and corrosive media. The analysis method used is polarization. Inhibition Efficiency Results obtained for Gas Corrosion Inhibitors (1A) at 10 ppm 96.86%, 20 ppm 59.74%, 30 ppm 74.48%. The Crude Corrosion Inhibitor (2A) results obtained inhibition efficiency for 10 ppm 99.57%, 20 ppm 77.69%, and 30 ppm 12.63%. The optimum value for the Gas Corrosion Inhibitor and Crude Corrosion Inhibitor is at 10 ppm at 96.86% and 99.57%.
