Abstract

Food security is a burden to realize sustainable development in achieving the zerohunger goal. This study aimed to examine the distribution of food security levels and the factors that influence the level of food security in the Special Region of Yogyakarta. Quantitative analysis was carried out in this study based on secondary data. The method of determining food security was carried out by applying the concept of the Food Security and Vulnerability Atlas (FSVA) which consists of three food pillars, namely food availability, access, and utilization. The results proved that Gunungkidul Regency was the area with the highest score for food availability, while the lowest were Bantul and Sleman. On the pillars of food access and food utilization, the highest was in Sleman, while the lowest was in Gunungkidul. The value of food security from the highest were the City of Yogyakarta (84.47), Sleman Regency (82.37), Bantul (79, 51), Gunungkidul (79.31), and Kulon Progo (79.03). All areas in DIY are included in very good food security. Food security policies need to be directed at handling food-poor households in villages through increasing knowledge about nutrition. Meanwhile in urban areas, it can be done through expanding job opportunities and community empowerment.

Abstract

Abstract: The increase in the population impacts the increasing demand for food and non-food. Hence, to fulfill non-food needs, agricultural food land is converted into non-agricultural. It affected the carrying capacity of food agriculture. This paper aimed to analyze changes in the carrying capacity of food agriculture and the factors that influence the carrying capacity of food agriculture in the Kulon Progo Regency. This study used a descriptive-quantitative approach with spatial-temporal analysis techniques on secondary data, including population, rice field area, and rice field productivity for 2011, 2015, and 2019. The results showed that in 2011 Kulon Progo Regency could not be self-sufficient in food. However, in 2015, the research area had a great carrying capacity for food agriculture and continues to increase. This increase was influenced by the addition of rice fields and increased productivity. On the other hand, the reduction of rice fields decreased the productivity of rice fields, and the increase in the population led to a decrease in the carrying capacity of food agriculture in the Nanggulan, Kalibawang, and Samigaluh Districts. The rice field area and the productivity of rice fields affect food availability, while the population affects food needs. This paper showed that land-use changes in agri-food land (rice field area and productivity of rice fields) and the number of populations resulted in changes in the carrying capacity of food agriculture. Keywords: Carrying capacity, land use change, food self-sufficiency, rice field, population growth

Abstract

The development of transportation infrastructure increases the pressure on natural resources, one of which is the increase in the built-up area. The changes do not only happen during the construction of transportation infrastructure but also after its completion. Therefore, this study aims to identify and simulate land use/cover changes in Kulon Progo Regency, Indonesia, to predict the effect of the construction of Yogyakarta International Airport (YIA). A quantitative descriptive method was used with the main data of multitemporal Landsat remote sensing images. Furthermore, the integration of Cellular Automata and Artificial Neural Networks (CA-ANN) was applied to simulate land use/cover change predictions (2035). The results of image classification using the supervised maximum likelihood classification showed an overall accuracy of 85.33% and 86.67% for 2011, and 2015 with 2019 using Landsat 7 and 8 images, respectively. Meanwhile, there was an increase in paddy fields of 1,210.1 ha (2.11%) and built-up area by 2,708.6 ha (4.72%) during 2011 – 2019. Conversely, shrubs and dryland agriculture decreased by 1,594.1 ha (2.78%) and 2,174.1 ha (3.79%). The simulation results indicate that the development of transportation infrastructure further triggers the increase in built-up area, especially around the YIA. Therefore, policymakers and development implementers should adopt and implement appropriate and effective planning for sustainable land use.

Abstract

Abstract.  The condition of water fertility is the most significant factor affecting the presence of fish. it depends on the content of chlorophyll-a. This study aims to detect the distribution of chlorophyll-a for pelagic fishing in Indonesian waters (WPPN-RI 713). Detection of chlorophyll-a can be more easily and efficiently carried out by using remote sensing image analysis processed through a geographic information system (GIS). This technology plays an important role in supporting and covering the shortcomings of conventional chlorophyll-a detection. Spatially, the concentration of chlorophyll-a suitable for pelagic fish is mostly found in coastal areas or river estuaries, in contrast, it is lower towards the sea. Based on the monsoon, the water areas with the appropriate concentration of chlorophyll-a mostly occur in the west monsoon, transition I, and east monsoon. While in transition II there will be a decrease in the area of water with the appropriate concentration of chlorophyll-a.There are many suitable water areas in the Makassar Strait, namely, along the western coast of Kalimantan and South Sulawesi. The results of this study are expected to help support the development of fishery activities and the management of marine resources in WPPN-RI 713. Keywords: Chlorophyll-a, Chl, Pelagic fish, Monsoon, citra MODIS

Hasil SWOT menunjukkan bahwa lokus strategi terbaik berada pada kuadran I (0,55; 0,68) (strategi agresif), yaitu memaksimalkan kekuatan serta peluang untuk meraih keuntungan berkelanjutan. Strategi tersebut mencakup tiga poin utama: (1) penerapan konsep silvofishery-ecopreneurship, yang memadukan budidaya dengan pelestarian ekosistem mangrove, dan (2) peningkatan peran lembaga masyarakat dalam pengelolaan kawasan mangrove. (3) pemberdayaan masyarakat untuk menciptakan kemandirian dengan inovasi yang berbasis kegiatan budidaya berkelanjutan. Implikasi dari hasil ini adalah bahwa pendekatan ecofishery-ecopreneurship perlu dipertimbangkan dalam pengembangan kebijakan pengelolaan hutan mangrove di berbagai lokasi. Tittle: Silvofishery Ecopreneurship – A Strategy for Developing Mangrove Ecosystem as a Sustainable Aquaculture Area Mangrove forests are potential to be developed as sustainable cultivation areas to increase the income of coastal communities. This study aims to analyze the strategy for developing cultivation areas in mangrove ecosystems without destroying their ecological functions. A qualitative descriptive method was conducted in this study based on primary data obtained from in-depth interviews. Sampling using the purposive sampling technique based on the profession of the respondent. The data of respondents are verified by observation and documentation. The data were analyzed using SWOT analysis (Strengths, Weaknesses, Opportunities, Threats). The research location is a mangrove forest ecosystem in Sanrobone District, Takalar Regency, where the community carries out fishing and fish farming activities in the surrounding area. The SWOT analysis results show that the best strategic locus is in quadrant I (0.55; 0.68) (aggressive strategy), namely maximizing strengths and opportunities to gain sustainable profits. The strategy includes three main points: (1) application of the silvofishery-ecopreneurship concept, which combines cultivation with the preservation of mangrove ecosystems, and (2) increasing the role of community institutions in managing mangrove areas. (3) community empowerment to create independence with innovation based on sustainable cultivation activities. The implication of these results is that the ecofishery-ecopreneurship approach needs to be considered in the development of mangrove forest management policies in various locations.

Abstract

The mangrove ecosystem faces significant challenges, as its quality and quantity are threatened with decline. This study aimed to analyze the mangrove density and macrobenthos diversity in the Ampekale Ecotourism Village, Indonesia. This research utilizes remote sensing image analysis through the Normalized Difference Vegetation Index (NDVI) method. Complementary ground-check surveys were conducted to ascertain the density and diversity of mangrove and macrobenthos species. The overall mangrove density in the Ampekale area was relatively high, with some areas displaying moderate density. The sequence of mangrove species, from most common to least common, includes Rhizophora mucronata, Avicennia marina, Avicennia alba, Rhizophora apiculata, Sonneratia alba, Bruguiera gymnorhiza, and Acanthus ilicifolius. The most prevalent macrobenthos belong to the Crustacea class, such as Uca sp., Sesarma, Metaplax sp., and Scylla serrata. Moreover, the most diverse macrobenthos belong to the Gastropods class. The distribution of this biodiversity depends on their location (coastal or inland), tidal fluctuations, and river estuaries. Mangrove ecosystems situated in estuaries with high densities exhibited elevated macrobenthos abundance. This correlation suggests that areas characterized by dense mangroves also harbor stable ecosystem conditions with abundant macrobenthos. In contrast, ecosystems featuring lower biodiversity demonstrated reduced stability. These findings contribute valuable insights into the conservation and sustainability of mangrove ecosystems. Keywords: ecotourism, macrobenthos, mangrove density, mangrove ecosystem, NDVI

Abstract

Thermal fronts are pivotal in shaping the marine ecosystem, influencing the presence and distribution of marine species. This study delves into the fluctuating patterns of thermal fronts in Indonesian waters, specifically focusing on the State Fisheries Management Area of the Republic of Indonesia, known as WPPNRI, 713. We identified the distribution and frequency of thermal fronts across different monsoon seasons. Utilizing the extended Cayula Cornillon Algorithm – Single Image Edge Detection (CCA-SIED), we deploy a precise methodology for detecting these fronts, relying on sea surface temperature (SST) gradients to identify specific periods and regions. Our analysis encompasses extensive satellite data collected from Moderate Resolution Imaging Spectroradiometer (MODIS) level 3. Our findings unveil distinct seasonal variations, with a decrease in thermal fronts during the west monsoon and a surge during the east monsoon. Moreover, we identify regional disparities, with denser thermal fronts observed in the southern and middle regions compared to the northern areas. Furthermore, our study underscores the critical need to integrate oceanographic data with fisheries management strategies to address the impacts of climate variability on marine resources. The observed relationships between thermal fronts, nutrient distribution, and fish migration emphasize the necessity for ongoing, localized monitoring to develop adaptive management solutions. This research marks a significant step in characterizing thermal fronts in WPPNRI 713, laying the groundwork for future investigations into other ecologically significant fronts, including those related to chlorophyll, salinity, and nutrients, thereby enhancing our understanding of marine ecosystem dynamics.Keywords: Cayula Cornillon; Fishing Zone; Marine Ecosystem; Sea Surface Temperature; Thermal Fronts
