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.

Abstract

Perubahan iklim dan tutupan lahan mengakibatkan peningkatan aliran permukaan (surface runoff) dan debit Sungai yang berpotensi dalam peningkatan frekuensi dan intensitas banjir. Salah satu daerah yang mengalami masalah ini adalah Kecamatan Dayeuhkolot yang terletak di DAS Citarum Hulu. Oleh karena itu, penelitian ini, dengan tujuan memprediksi perubahan debit dan limpasan Sungai Citarum di Kecamatan Dayeuhkolot pada tahun 2045 dengan mempertimbangkan skenario perubahan tutupan lahan dan iklim disusun agar dapat menjadi masukan dalam strategi rehabilitasi lahan di DAS Citarum Hulu. Dalam penelitian ini, dilakukan simulasi perubahan penggunaan lahan dari tahun 2022 hingga 2045 menggunakan model CA-Markov dengan skenario Business as Usual (BAU). Selain itu, dilakukan Statistical Downscalling Model (SDSM) untuk menganalisis tren perubahan iklim pada tiga skenario berbeda. Setelah itu, kombinasi dari masing-masing skenario perubahan penggunaan lahan dan iklim, akan dimodelkan dalam model hidrologi Soil and Water Assessment Tool (SWAT) untuk mensimulasikan aliran air masa depan dan menganalisis risiko banjir masa depan. Hasil penelitian menunjukkan peningkatan limpasan tahunan tertinggi terjadi pada skenario perubahan iklim RCP 8.5 dan skenario perubahan tutupan lahan Business As Usual, yaitu sebesar 24,42%. Selain itu, peningkatan debit tertinggi terjadi pada skenario perubahan tutupan lahan dengan skenario Business As Usual dan skenario iklim RCP 8.5, yaitu sebesar 91,84%.

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

Ensuring the availability and sustainability of clean water is a key focus of the United Nations Sustainable Development Goals (SDGs) and has emerged as a significant concern for both central and local governments in Indonesia. In the Kapongan District of Situbondo Regency, the government's PAMSIMAS Programme is a proactive initiative designed to secure safe access to drinking water for the community. Within this district, two villages, Landangan and Pokaan, have successfully implemented community-based drinking water provision. The ongoing sustainability of these water supply systems in these villages is pivotal for meeting the continuous drinking water needs of the community, necessitating a comprehensive investigation into its sustainability. The primary objective of this study is to assess the sustainability status of community-based drinking water provision within the ongoing PAMSIMAS program in Kapongan District. The dimensions under consideration encompass environmental, social, economic, technological, and institutional aspects. Employing a quantitative approach, the research utilizes the Rap-SPAM analysis method, a modification of Rapfish, with primary data collected through surveys, observations, and interviews. Additionally, secondary data is acquired through an extensive literature review and consultation with various related agencies. The assessment results reveal a sustainability index of 58.92, classifying it as reasonably sustainable. The Multi-Dimensional Scaling (MDS) model produced Stress values ranging from 0.15 to 0.18 and R2 values between 0.93 to 0.94. The variance between the MDS index and Monte Carlo analysis is less than 5%. In conclusion, this study finds that the community-based water supply facilitated by the PAMSIMAS program in Kapongan District demonstrates a reasonably sustainable status. To enhance its sustainability, there is a need to prioritize and improve dimensions with lower sustainability index values in a holistic manner.ABSTRAKMemastikan ketersediaan dan keberlanjutan air bersih merupakan fokus utama Tujuan Pembangunan Berkelanjutan (SDGs) PBB dan menjadi perhatian besar bagi pemerintah pusat dan daerah di Indonesia.

Abstract

The restoration of mangrove forests is a crucial endeavor to restore damaged areas. The area that needs restoration is the mangrove forest located in Rambut Island Wildlife Reserve. This particular mangrove forest spans approximately 14.31 hectares, with a research site covering 2.14 hectares in the western part of Rambut Island. The objectives were to accurately map the mangrove forests’s location and size that require restoration, identify mangrove species, and determine suitable restoration techniques. Sentinel-2A imagery data and field surveys conducted from July to August 2022 mapped the forest area and collected primary data on vegetation, soil, inundation, and water salinity. Based on the findings, it has been determined that approximately 0.37 hectares of the area require restoration measures. The recommended mangrove species for restoration consist of Avicennia sp., Bruguiera sp., Rhizophora sp., Ceriops sp., Heritiera sp., Sonneratia sp., and Xylocarpus sp. The planting technique that can be applied to all restoration plots, except for plot number 7, is the cemplongan technique, while the Bronjong technique is recommended for plot number 7.
