Abstract

This research aims to create a model for predicting clean water need in the urban area Sentul City currently and next 30 (thirty years). To create the model, it is required data which are useful for forecasting the inhabitant number year to year. There are some general-used models for forecasting the inhabitant number, including to arithmatic, exponential, and least square method. The inhabitant number forecast in this research used an exponential method, as recommended in the Guidance of River Area Water Resource by Directorate General of Water Resource in 2001. The researcher used the software Stella 9.0.1 for simplifying the modeling process, projecting the inhabitant number, predicting the clean water need, and figuring the graphics. Besides this software, Excel programme was also used. According to data analysis result, the equation models to predict water need (m3/year) in Sentul City are stated as follows; for rural area inhabitants: YDn = 1 927 309 (1 + 0.0303)n; for urban area inhabitants: YKn = 1 808 940 + 217 248*n;  and for total inhabitants: YSCn = YDn + YKn.Keywords: inhabitant number, geomeric method, clean water need prediction

Abstract

The purpose of this study is to create a peak runoff model in urban SC areas based on existing land use/land cover (LU / LC) and a master plan. To calculate peak runoff (PRO) using the rational method. To find out the current LU / LC through existing SPOT-6 image analysis in 2017, using supervised classification method with an estimation of gamma distribution parameters with the maximum likelihood method using QGIS 2.8 software, SAGA GIS, and Arc -GIS 10.4.1. Based on the results of image analysis obtained twelve types of LU, which can be grouped into three types of LC, namely 33% of developed land, 65% of vegetated land (RTH), and 2% of blue open land (RTB). The analysis shows that the implementation of the master plan increases PRO. With the increase in PRO will contribute to flooding in the downstream areas, consequently the developer must be responsible for reducing the PRO.

Abstract

This study aims to predict the current and future demand for clean water, and efforts to develop clean water supply from a social aspect in Sentul City (SC). To estimate the need for clean water, it is predicted from the total population from year to year. Forecasting population in this study uses arithmetic and geometric methods, while Stella software is used to facilitate the analysis. Starting in 2030, it is estimated that SC will experience water shortages. The Community Based Drinking Water Supply and Sanitation or PAMSIMAS program and installation of smart tanks are proposed to overcome the problem water shortage of rural residents in SC. Meanwhile, for urban residents, they can collect rainwater that falls on the roofs of houses and collect it in smart tanks. The implementation of PAMSIMAS program and the installation of smart tanks in SC has an important function as a supplier of backup raw water sources to overcome current and future shortages of clean water.

Abstract

Local community's activities around Labanan forest area for specific purposes already make the area unsafe. Responding to this, land productivity optimization with agroforestry patterns might be applied in the area. Hopefully, through these systems, utilization and productivity of natural forests in Labanan forest area might be optimized in producing food, energy and water conservation, outside its regular function as forestry area. The purpose of this study was to determine the condition of the land under treeing forest; generate analytical data of vegetation in the research plots; and determine carbon stocks undergrowth. The research method was soil sampling, vegetation analyzes and sampling of undergrowth plant biomass. Based on laboratory analysis result, soil pH ranging between 5-7, N Total <0.3%, P Total <49 mg P2O5.100g-1, K Total between 2-8 mg K2O.100g-1, and the organic carbon content on soil <2.1%. The vegetations dominated by cunday (Saraca declinata) as many as 43 trees/ha with basal area 21.55 m2. ha-1. The highest important value index (IVI) shown by the type of vegetation cunday (Saraca declinata) amounted to 51.43% and the lowest was shown by bintangur (Callophyllum sp) amounted to 2.89%. Stock carbon undergrowth on research area ranged from 1.470 to 1.752ton C. ha-1.

Abstract

The pandemic causes the need for new jobs. Most workers from rural areas experienced many layoffs due to the significant reduction in employment opportunities. One of the jobs that can be an option to accommodate these workers is the tourism sector. With community-based tourism, local workers can be absorbed by areas with natural tourism potential. The challenge faced by prospective tourist objects is how significant the potential of the tourism object is and how much the tariff will be set. This study aims to find the economic potential of the object of research used by the micro tourism manager in determining the rates or price ranges used in the sale of culinary or other goods/services. This study uses environmental valuation with the Travel Cost Method to calculate several potential economic objects to be used as the basis for investors to invest in research objects. In addition, managers can also use the average willingness to pay (WTP) as the basis for entrance fees, parking, and culinary prices offered. Considering visitors' preferences is a tourist attraction that looks free; the WTP value for the entrance fee is IDR 0. This study concludes that without managing micro-tourism objects, the value is IDR 63.129.290.00 to IDR71.835.382,00, while if it is managed, the potential increases to IDR5.752.023.104,00. The recommended culinary price is no more than IDR12.084,00, while the parking fee can be collected at IDR 1.000,00.
