Abstract

The objectives of the research were (1) to analyze the value of the biocapacity and ecological footprint in Sleman Regency; (2) to measure and analyze the value and spatial distribution of bioecological carrying capacity in global hectare units (global hectare); and (3) formulating the direction of development and control of development based on the class of bioecological carrying capacity. The research was conducted using a quantitative approach through processing and analyzing secondary data from various sources. Secondary data that is processed is data at the village level. The determination of the bioecological carrying capacity is based on the calculation of the ecological footprint as a manifestation of the level of consumption that reflects the population’s needs, and biocapacity which is the embodiment of the aspect of land use in providing resources. Based on the current conditions and land use composition, the Sleman Regency area only has a biocapacity value or can only support each resident with a land area of 0.20 hectares global/person. On the other hand, the value of the ecological footprint or the level of need reaches 0.279 global hectares/person. Thus, the bioecological carrying capacity in Sleman Regency has a value of 0.87 or a deficit of 0.078 hectares globally per capita. That shows that the Sleman Regency area has experienced an overpopulation with current productivity and land use. The low carrying capacity of bioecology in Sleman Regency is also reflected in the fact that most villages are classified as having low carrying capacity, reaching 68%. However, many villages still have a high bioecological carrying capacity (1.2), especially in the northern and western parts of the Sleman Regency. The primary attention needs to be devoted to villages with a low bioecological carrying capacity, which is 58 villages. In these villages, the direction of development needs to be emphasized in controlling land use change and increasing productivity, limiting business scale, and controlling population growth rates.

Abstract

Abrasi merupakan salah satu fenomena alam yang biasanya terjadi di wilayah pantai. Fenomena ini menjadi serius ketika terus mengalami tren penurunan dan mengganggu kawasan permukiman di pesisir pantai.  Kecamatan Wawonii Barat merupakan salah satu kecamatan yang wilayah pesisirnya mengalami abrasi dan akresi. Namun, kajian mengenai perubahan garis pantai belum dikaji berdasarkan Rencana Tata Ruang Wilayah. Tujuan penelitian ini ada untuk memantau, menganalisis serta mengevaluasi laju perubahan garis pantai sesuai rencana tata ruang wilayah Kecamatan Wawonii Barat yang tertuang dalam pola ruang Kabupaten Konawe Kepulauan tahun 2021-2040. Metode yang digunakan adalah metode kualitatif teknik Digital Shoreline Analysis System (DSAS) yang diintegrasikan dengan Google Earth Engine (GEE) untuk indentifikasi abrasi dan akresi. Analisis penyebab, dampak dan rekomendasi dilakukan secara deskriptif kualitatif. Overall Accuracy dan Kappa Coefficient dari semua peta masing-masing 0,93 dan 0,86. Garis pantai telah mundur hingga -10,58 m/tahun dengan kemunduruan tertinggi sebesar -264,2 m/tahun. Rekomendari yang diusulkan adalah mengevaluasi kembali RTRW khususnya terkait rencana sistem jaringan prasarana jalan dan kawasan ekosistem mangrove, membuat telud dan teluk pemecah gelombang pada kawasan pesisir yang berhubungan langsung dengan permukiman dan penanaman mangrove di sepanjang pesisir pantai.

Abstract

One of the new tourist objects in North Gorontalo Regency is Diyonumo Island and until now it has not been optimally developed both in terms of its feasibility as a tourist area. So it really needs intervention from both the government and the private sector to encourage tourism development in North Gorontalo Regency which is based on nature. But there is no information system that provides an overview of this tourism potential. So the researchers identified the tourism potential of Diyonumo Island using a geographic information system in North Gorontalo Regency. The method used in this study was SWOT integrated with a spatial approach to analyze each parameter, namely attractions, infrastructure and accessibility. Based on spatial mapping, Diyonumo Island tourism can be recommended as a strategic tourism area for Gorontalo Province. The results of the analysis show that Diyonumo Island has a percentage of 40% of tourist attractions that have the potential to be developed and become a supporting strategy to increase the number of tourist visits.

Abstract

On 12 May 2021, 12 August 2021, 6 September 2021 and 27 June 2022, extreme rain occured with an intensity of 58.85 mm/day, 101.3 mm/day, 124.4 mm/day and 176.8 mm/day respectively in East Kotawaringin. These phenomena occurred during the dry season and caused flooding, which is a rare condition during the dry season in East Kotawaringin. This study aims to evaluate extreme rainfall using GSMaP (Global Satellite Mapping of Precipitation) data, where analysis using GSMaP has never been done before in East Kotawaringin. These GSMaP data were processed and compared with the observation data from the Meteorological Station of H. Asan, East Kotawaringin. After that, the GSMaP rainfall results are verified using statistical methods, namely RMSE, correlation coefficient and bias. The verification results show that the bias gives underestimate results for all dates. In addition, the RMSE values on 12 May 2021, 12 August 2021, 6 September 2021 and 27 June 2022 are 10.83, 17.32, 12.41 and 34.03, respectively. These high RMSE values indicate that the GSMaP rainfall value is quite far from the observed rainfall value. The correlation value between GSMaP rainfall and observations has a high correlation with values of 0.84, 0.90, 0.96 and 0.98 for each date. These results show that the GSMaP data has a good correlation value and can be used for extreme rainfall analysis at the Meteorological Station of H. Asan, East Kotawaringin.

Abstract

Drought is one of the natural disasters that causes substantial losses to food crop production, water supply in several important sectors such as industry, settlements, and agriculture. Climate change often causes drought on agricultural land and can indirectly threaten livelihoods and food security. This study aims to analyze the distribution of drought on agricultural land and examine the relationship between physical conditions. Drought monitoring study using remote sensing methods on Landsat 8 OLI imagery with the Normalized Difference Drought Index (NDDI) algorithm is the result of combining two parameters, namely the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI). The results of the study show the distribution of agricultural land drought in Palabuhanratu District, Sukabumi Regency during 2018-2021 with five classes (normal, mild, moderate, severe, and very severe), and a very severe drought category of 80.78 ha in 2021, followed by 2018 an area of 32.09 ha. The most potential drought areas are in Palabuhanratu District, namely Jayanti Village and Citepus Village.
