Abstract

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.

Abstract

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.

Abstract

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.

Abstract

The rain that fell in the city of Cirebon, especially the drainage on Jalan Pemuda, could not accommodate and drain the water so that it could create puddles on the roads and surrounding areas. Hourly rain intensity, planned flow rate and channel cross-sectional dimensions are the first steps for flood prevention. Hydrological analysis is used to calculate the discharge capacity of the drainage plan. The results were then analyzed the dimensions of the channel, the drainage ability to accommodate the falling rainwater where Qs is bigger than Qp. the channel discharge has not been able to accommodate the Q plan in the channel so that there will be a runoff of 17.759%. So to anticipate runoff, it is necessary to have a channel improvement plan of 33.477%. In addition to channel improvement solutions, arrange and define the boundaries of water storage areas by measuring and mapping boundaries and issuing regulations that prohibit or limit the construction of buildings that can reduce the ability of areas to store and absorb rainwater by referring to the basic building coefficient (KDB) permitted as stated in the RT/RW.

The potential for natural and river tourism along with the community mortar home industry are some of the attractions that motivate BUMDes Rancang Jaya to develop it as a tourist village. BUMDes Rancang Jaya, as a newly established company owned by the Village of Sinarancang, has a vision of creating a tourism village called Sinarancang, which is able to attract Cirebon tourists to visit. BUMDes Rancang jaya has been observing and studying other BUMDes that have succeeded in developing tourist villages and attracting tourists. They see the motivation of tourists in visiting Sinarancang Village because of its location near Setu Patok with beautiful views. This is one of the reasons why tourism needs to be developed for developing villages as a means of capturing new opportunities in meeting community needs. The purpose of this study is to identify entrepreneurial characteristics that are applied in business development carried out by BUMDes and to describe the concept of BUMDes leadership which has entrepreneurial characteristics in realizing the development strategy of the Sinarancang tourism village. This study used a qualitative descriptive method with secondary data analysis in the form of village policy documents and primary data analysis from observations and interviews. Regional leadership needs to demonstrate entrepreneurial characteristics. In this case, the leadership of BUMDes Rancang Jaya has shown the beginnings of entrepreneurial characteristics according to Schumpeter (1934) and Kirzner (1973), namely believing in change and making innovations in institutional settings. To realize the development strategy of the Sinarancang Tourism Village, it requires BUMDes leadership with entrepreneurial insight, namely those that fulfill 6 entrepreneurial characteristics in the context of regional development (Stimson, 2009), so that the motivation of entrepreneurship in the context of regional development is realized, namely creating individual economic benefits that occur from cultural enhancement or the regional economic context (business climate) and social welfare as well as community benefits stemming from spillover and institutional effects.Keywords: Sinarancang, Tourism Village, BUMDes, Regional Leadership, Entrepreneurship

Abstract

In this pandemic era, doors in public places are one of the objects that can be an intermediary for the transmissionof the Covid-19 virus. That's why various kinds of developments in the field of technology are designed to provide an alternative in avoiding the transmission of the Covid-19 virus through doors in public places.The purpose of this study is to design an Arduino Uno-based automatic door simulator using Proteus software. The sensor used in this system is a PIR (Passive Infra Red) sensor. The way the system works is that when the PIR sensor detects someone's movement, the Data OUT Pin will be HIGH. Because this pin is connected to the Arduino, it will detect this HIGH Signal and detect that someone is approaching the door and will provide input to the DC motor, then the DC motor will move to the right or left to pull the door. From the simulation results, the delay between sensor readings and the movement of the DC motor is about 3 to 5 seconds.
