Analysis of willingness to pay (WTP) to support the sustainability of geotourism at Wediombo Beach, Gunung Kidul
No full textThe increase in tourism activities in the geotourism area of Wediombo Beach have triggered a cascade of effects, including economic growth and environmental degradation. To mitigate further environmental harm and support its preservation, financial backing is essential, particularly as this area is part of the UNESCO Global Geopark Gunungsewu. This research investigates the Willingness to Pay (WTP) of visitors at Wediombo Beach, seeking to determine their willingness to contribute to environmental protection and analyzing the factors influencing their WTP. The approaches used in this study are Contingent Valuation Method (CVM) and Travel Cost Method (TCM) to calculate WTP, utilizing multiple linear regression analysis to assess the impact of independent variables on WTP. This study uses multiple linear regression analysis to determine the effect of the independent variable on WTP. Through interviews conducted with 67 respondents of accidental sampling using the bidding game dichotomous question method.The findings reveal that Wediombo Beach is currently undervalued, as the average WTP to support the sustainability of geotourism at the site is IDR15,615.00 per individual per visit, totaling IDR99,782,308.00. The key factors influencing visitors to the WTP at Wediombo Beach are perceived attractiveness and educational value. © 2023 EDP Sciences. All rights reserved

The Analysis of Fire Hotspot Distribution in Kalimantan and Its Relationship with ENSO Phases
No full textKalimantan experiences fire hazards almost every year, which threaten the largest tropical forest in Southeast Asia. Climatic conditions, such as increasing surface temperature and decreasing rainfall, become important especially when El Nino Southern Oscillation (ENSO) occurs. Studies on fire are commonly conducted based on the climatic condition such as the dry or wet season, but those which focused on analysis of fire occurrences with the specific ENSO phases are still limited. This study aims to identify the spatial and temporal distribution of rainfall, land surface temperature, and soil moisture and analyses the distribution of hotspots in Kalimantan from 2014 to 2020 during different ENSO phases. The data used are Moderate Resolution Imaging Spectroradiometer (MODIS) for hotspot analysis, Global Precipitation Measurement (GPM) for rainfall analysis, MODIS Land Surface Temperature (LST) for surface temperature analysis and Soil Moisture Active Passive (SMAP) for soil moisture analysis. The methods used were descriptive and spatial analyses based on each ENSO phase, which were then combined to analyse the temporal and spatial distribution of fire, rainfall, LST and soil moisture. The temporal distribution shows a positive relationship between ENSO, rainfall, LST, soil moisture and hotspots with a confidence level of 90 in the dry months of August-October. Fire occurred in most parts of West and Central Kalimantan, associated with low elevation, organic soil types and agricultural peatland. The average trend of increasing hotspots is 17.4 in the El Nino phase and decreasing hotspots by 84.7 in the La Nina phase during August-October in Kalimantan. © 2023 Rahma Aulia Zahra et al., published by Sciendo
Geomorphological and hydro-oceanographic analysis related to the characteristics of marine debris on the south coast of Yogyakarta, Indonesia
No full textBantul Regency in Yogyakarta has a shoreline of 16.85 km and is famous for its beach attractions, including Baru and Samas beaches. In Bantul, the Progo river is also recorded in the top 20 rivers globally, contributing to plastic waste pollution in coastal areas. Therefore, the problem of marine debris in Bantul is a serious matter because it can impact the environment and the tourism sector. However, marine debris characteristics in Bantul are still poorly understood. This research aims to determine the characteristics of meso- and macro-sized marine debris, its source and transportation, and the geomorphic and hydro-oceanographic processes that may affect it. A combination of geospatial analysis of high-resolution aerial photographs, field surveys with the transect method, and GIS approaches are used to achieve those objectives. Research shows that the marine debris found at Baru and Samas beaches in Yogyakarta is 149 pieces and 95 pieces, respectively. Macro-sized marine debris was dominantly found in Samas (80), and meso-sized marine debris was dominantly found in Baru (67). The total mass of marine debris in Baru and Samas beaches is 129 g and 1722 g, respectively. The vast amount of marine debris and smaller size in Baru is thought to have originated from land and was carried away by fluvial processes in the wider (2462.08 km2) and more elongated (Rb: 0.355) Progo watershed. Meanwhile, the larger mass of marine debris at Samas may be caused by the reflective beach typology (ε: 52.86), which can carry a higher abundance of marine debris. © 2022, The Author(s), under exclusive licence to Accademia Nazionale dei Lincei

No full textThe political arena influences the selection of an alternative policy for Samisake Revolving Fund program. In this phase, various interests affect the policy outcome, including conflict and bargaining positions among policymakers. Therefore, this study aimed to examine public participation in policy formulation for the Samisake Revolving Fund program in Bengkulu City, Indonesia. A qualitative method was used with a case study approach to the policy design, as well as typical conditions and variables. Data were collected by interviewing seven informants of five stakeholder elements and analyzed using flowing analysis. The results indicated high community involvement in the public policy formulation process that entails pushing issues into the policy agenda. The best policy alternative should satisfy all interested parties. Additionally, the policy was established by issuing the Regional Regulation draft on allocating the funding. This Regional Regulation should be accepted and implemented by all parties transparently with accountability to increase community participation and empowerment. The policy process displays a complex interaction among the policymakers. These policymakers include the executives of the Bengkulu City government from the Regional Technical Unit, community leaders and organizations, NGOs, and university academics. The interaction influences choices and policy decisions by creating conflict and tension in discussing the draft of Samisake Fund Regional Regulation. Therefore, future studies could examine stakeholder network participation in policy formulation and strengthening inter-institutional capacity to avoid conflict. © 2023 Mykolas Riomeris University.

Optimization of the Formulation of Sago Starch Edible Coatings Incorporated with Nano Cellulose Fiber (CNF)
No full textThis study aimed to produce new edible coatings based on the mixture of sago starch, cellulose nanofiber (CNF), glycerol, and tween-80.The effect of sago starch (5�10 g of starch/100 ml of distilled water), CNF (0.5�20 w/w), glycerol (10�30 w/w), and tween-80 (0.5�10 w/w) based on sago starch concentration on contact angle (CA), water vapor permeability (WVP), oxygen permeability (PO2) and tensile strength (TS) properties of the edible coatings were optimized using factorial experimental design (2k).The result showed that the linear model for all independent variables was significant (P<0.05) on all responses (dependent variable).The sago starch concentration depicted a significant (p < 0.001) positive effect on contact angle; CNF showed a statistically significant effect on WVP, PO2, and TS; tween-80 showed a significant effect on all dependent variables, whereas glycerol only affected WVP. The optimum concentrations of sago starch, CNF, glycerol, and tween-80 were predicted to be 5 g/100 ml distilled water, 20 w/w, 10 w/w, and 0.5 w/w based on sago starch, respectively to obtain the minimum contact angle, WVP, PO2, and the maximum TS. The predicted data for the optimized coating formulation were in good agreement with the experimental value. This work revealed that the potential of sago starch/CNF based coating formulation could be effectively produced and successfully applied for coating of food. © Universiti Putra Malaysia Press
