Identification of Forest City Multi-Policy Using the MULTIPOL: A Study In The New Indonesian Capital, East Kalimantan
Get PDFThe policy-planned development in the new Indonesia Capital City (IKN) area must be accompanied by good planning to ensure the continued availability of forestry ecosystem services, especially forestry areas. These ecosystem services are strongly influenced by their ecological functions. Humans depend on essential ecosystem services to satisfy their inherent needs and enhance or preserve their quality of life. Natural resources are being overused to satisfy these demands, endangering biodiversity and putting more strain on ecosystems. Therefore, a multi-policy approach describes and visualizes the relationships between multi-aspect policies that provide and benefit from forestry ecosystem services. The method used in compiling this paper is multi-policy, part of the prospective analysis method. This method will map and create a model, the best policy scenario that can be applied to achieve the goal of a forest city in the new nation\u27s capital. The results show that the presidential regulation implementation scenario is the best policy choice for the forest city model in the new state capital

Assessing Urban Level Changes Using GIS and Statistical Analysis in the Kedungsepur Metropolitan, Indonesia
Get PDFFrom 2010 to 2020, the Kedungsepur Metropolitan Corridor experienced spatial transformations, converting agricultural areas into built-up areas. This study seeks to identify new insights by examining the correlation between socioeconomic facilities and built-up areas, typically analyzed separately. Satellite imagery interpretation was used to determine the proportion of built-up areas, apply the K-Means Cluster method for the urban level, and conduct statistical analysis using the chisquare test. The findings reveal that the Semarang—Ungaran—Salatiga Corridor has the greatest built-up areas. The average change in built-up area within the Kedungsepur Metropolitan Corridor from 2010 to 2020 was 3.25%. Additionally, the Central Semarang Subdistrict had the highest level of socioeconomic facilities. However, the Chi-Square test results indicated differences between the observed and expected frequencies of built-up area percentages in each subdistrict for both 2010 and 2020. Surprisingly, no correlation was found between urban-level changes related to built-up areas and socioeconomic facilities. These results suggest that urban changes in the primary city are relatively stagnant, while more intensive development occurs in secondary cities withinKedungsepur. The dominant driving factor for urban transformation is the change in built-up areas,which indicates the intensified growth of secondary cities
Identifying the Strata of Sago Stands Using Unmanned Aerial Vehicle Data (Case Study: Ambon Island, Maluku, Indonesia)
Get PDFManual measurements to estimate the height and diameter of sago stems can be performed directly. However, estimates of height and diameter from land cover using remote sensing or aerial photographic coverage have not been widely featured in articles at home or abroad. To determine the potential and distribution of sago plant species that can be produced per area in the sago forest area, we mapped the sago land area using drone aircraft to cover the sago land area. We determined the diameter and height classes of sago plants using a Digital Surface Model (DSM) data application method. The results of the analysis showed that there was a distribution of diameter and height of sago plants varying according to height, namely for strata-level seedlings (0 to 6 m) as much as 100, saplings (6 to 12 m) as much as 818, poles (12 to 18 m) as much as 3,332, and trees (> 18 m) as much as 3.79. for the area of sago land mapped, and can be processed into an orthomosaic covering an area of 126,883 ha
Coastal Vulnerability Assessment Based on Coastal Vulnerability Index (CVI) on the Coastal Area of Kolaka Regency, Southeast Sulawesi, Indonesia
Get PDFThe purpose of this paper is to investigate vulnerability assessments along the coastal area and small island of Kolaka Regency, Southeast Sulawesi, Indonesia. This paper used spatial analysis to estimate the Coastal Vulnerability Index (CVI). An assessment of CVI was carried out using eight parameters to build into five categories, with very low to very high category vulnerability. Coastal vulnerability in the Kolaka coastal area varies from a very low to a very high category. Hence, this study suggests that policymakers need to make a long-term plan for local coastal zones, and they should prioritize a precision disaster-based analysis to minimize the damage caused by the disaster in the future

Tujuan penelitian ini, antara lain: mengetahui kandungan C-Organik sedimen; mengetahui karbon serasah; dan mengetahui pengaruh C-Organik dan karbon serasah terhadap kesehatan tapak (pH dan KTK tanah). Adapun tahapan penelitian, antara lain: pengambilan sampel sedimen dan serasah pada plot pengamatan; analisis sampel sedimen dan serasah di laboratorium; perhitungan karbon serasah berdasarkan berat kering; dan analisis kesuburan terhadap kesehatan tapak menggunakan analisis Regresi Linear Berganda. Berdasarkan hasil penelitian, menunjukkan bahwa: C-Organik tertinggi berada pada Klaster-Plot 3 (CL3); karbon serasah tertinggi pada CL2; dan terdapat pengaruh signifikan antara kesuburan tapak (C-Organik) terhadap kesehatan tapak (pH). Faktor-faktor yang mempengaruhi kondisi tersebut, antara lain produksi serasah, bahan organik, temperatur, jenis pohon, polusi, dan iklim. Dengan demikian, kondisi sedimen yang tinggi bahan organik berpengaruh terhadap kesehatan tapak (pH dan KTK sedimen). Namun, saat ini kondisi tapak di LMC sedang terganggu akibat tumpahan minyak. Oleh karena itu, perlu adanya pemulihan ekosistem dan kondisi tapak untuk menjaga fungsi mangrove sebagai pengikat karbon dan supaya kondisi kesehatan tapak berkelanjutan.Subsurface carbon storage reflects the fertility of mangrove sites. Site fertility has implications for site health. The aims of this study, among others, are to determine the content of C-organic sediments, determine the litter carbon content, and understand the effect of C-organic and litter carbon on on-site health (soil pH and CEC). The stages of research, among others, are sediment and litter sampling on the observation plot, analysis of sediment and litter samples in the laboratory, calculation of litter carbon by dry weight, and fertility analysis of site health using multiple linear regression analysis with a significant threshold of 95%. Based on the results of the study, the highest C-organic content was observed in cluster plot 3 (CL3); the highest increase in litter carbon was at CL2, and there was a significant effect between site fertility (C-organic) and site health (pH). The pH and carbon play a role in the mobility of compounds that form organic materials. Factors influencing on-site carbon health conditions include waste production, organic material, temperature, tree species, pollution, and climate. Sediment conditions affect sigh in organic matter and the health of the site. The results of this research can illustrate the fertility and health conditions of sites inmangrove forests, so regulations can be formulated to prevent damage to mangroves. 
Water Balance Prediction by Simulating Land Use Planning and Water Retention Infrastructure in Upper Cisadane Sub-Watershed, West Java, Indonesia
Get PDFCurrently, water resources management is still focused on on-site water resources infrastructure to achieve optimal water utilization, with almost never considered land management in which water resources are produced naturally. The research aim is to study the water balance in the Upper Cisadane Sub-Watershed, and to simulate a land use plan and development of water resource infrastructure to fulfill the need for water in the Upper Cisadane Sub-Watershed using the SWAT (Soil and Water Assessment Tool) model. Existing water availability was calculated using stream discharge data from River Flow Measurement Station Empang, whereas water demand has been analyzed for domestic, industries, agriculture, fisheries, and animal husbandry. Totally, water availability in the Upper Cisadane Sub-Watershed was ± 222.9 MCM (Million Cubic Meters) year-1, which was higher than the demand for water of as much as ± 209.8 MCM year-1 and resulted in a water surplus of ± 13.1 MCM year-1. However, water availability was not evenly distributed throughout the year, and there was always a water deficit in the dry season. To overcome drought during the dry season, five simulations of land use management and construction of water retention infrastructure were carried out using the SWAT model. The water deficit in the Upper Cisadane SubWatershed will be overcome by the consistent application of the spatial plan of West Java Province, reforestation of converted forest areas, applied agroforestry in agricultural land, and development of a reservoir with a storage capacity of 30 MCM
