Abstract

Sinarancang Village as the Setu Patok area has the potential for natural tourism and potential open public spaces. Sinarancang Village has a strategic location because it is close to Setu Patok. 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

Soil stability is an effort made to improve the properties of the origin of the soil, basically stabilization using salt has the same principle as stabilization using other chemicals. Based on the research on native soil combat, the value of 42.25% is categorized into soil types have high plasticity therefore the soil needs repair or stabilization.In this study chemical stabilization was carried out by adding ingredients to stability of salt (Nacl) with a percentage of 4% , 8%, and 12% of the weight of the sample. The research method used is divided into two, namely physical properties test consisting of water content test, density test, atterberg test and filter analysis test and mechanical properties test consisting of compacting test and consolidation test .The results of physical properties test showed that the greater the percentage of NaCl addition in water content, plastic limit, shrinkage limit increased while the specific gravity value, liquid limit, plasticity index and pass filter No. 200 decreased. While in the compaction test the weight value of the maximum dry volume increases and the optimum water content value decreases along with the percentage addition of NaCl. The maximum weight value of maximum dry volume is 1.675 gr / cm3 and the lowest optimum water content is 15.509% in mixed soil with the percentage of addition of 12% NaCl. Meanwhile the consolidation test results showed that the greater percentage percentage of NaCl consolidation coefficient (Cv) increases , while for the Cc index value and the consolidation decrease (Sc) decreases.Keywords : clay soil, Stablizing,Consolidation , salt (NaCl).

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

ABSTRACTRivers drain water by embracing a gravitational philosophy, in which water always flows from high to low or downstream to downstream. The process of river water flow is an endless natural process, closing the hydrological cycle by restoring the river runoff to the sea. For centuries, rivers have been used as a source of clean water, meeting human needs for drinking water, sanitation, irrigation, and so on. Large rivers are dammed to store water in the wet season and use it in the dry season for various purposes.Kali Gung or Kaligung or also known as Kaligung river is a river that flows in Tegal regency, Central Java. This river is one of the largest rivers in Tegal besides Kali Ketiwon and Kali Kemiri. This river is called Kali Gung because it is tangent to the spring that comes from Mount Agung is an ancient name from Mount Slamet in pre-Islamic times in Java. Upstream or spring water Kaligung located in the north of Mount Slamet and empties to the north precisely in the sea of Java.Keywords: Hydrologycal cycle, rivers, downstream, upstream, Kaligung.

Abstract

Flood is the disaster with the highest frequency occurrence in the world resulted in the greatest loss of both material and nonmaterial. This loss is exacerbated by the incidence of floods that occur in urban areas that have large population and asset values. Efforts to reduce the risk of urban flood disaster have been done, but this effort is still sectoral. This article examines how flood risks are integrated into urban spatial planning in Indonesia. The integration of floods in Indonesia is carried out with an environmental assessment approach in the development plan, with a Strategic Environmental Assessment/SEA (KLHS) attached to each development plan.
