Abstract

Pekalongan is one of the coastal areas of Java Island that is affected by tidal floods. Tidal floods have various impacts on the social and economic conditions of the community, thus affecting their livelihoods. The purpose of this study was to examine the impact of a tidal flood, the socioeconomic characteristics of the community and the survival approach of coastal communities in Pekalongan. This study was conducted using a purposive sampling method in two villages in Pekalongan Regency, namely Jeruksari Village and Tegaldowo Village, because these two areas are affected by tidal floods. The study was conducted by using in-depth interviews and focus group discussions (FGDs), as well as structured interviews. The structured interview sample consisted of 60 respondents who were selected at random using quota sampling. The analysis was using qualitative-descriptive and quantitative methods. The gathered data were then presented in tables, diagrams and maps. The results showed that tidal floods resulted in physical, economic, sociocultural, health, educational, and environmental damages to the communities in both villages. The majority of the community members only have an elementary school education and primarily work as labourers. There is a difference in the amount of family income between the two villages, where the average family in Jeruksari Village has a higher income (IDR 3,465,300 per month) than the average family in Tegaldowo Village with total household income of about IDR 2 million per month. The most frequently used approach for survival in both villages is what is known as the survival strategy, i.e. a strategy to meet the needs of life at a minimum level to survive.

Abstract

Jasa ekosistem mangrove terbagi menjadi jasa penyedia, jasa pendukung, jasa kebudayaan, dan jasa pengaturan yang bermanfaat bagi manusia dan lingkungan. Jasa pengaturan ekosistem mangrove berfungsi sebagai perlindungan terhadap ancaman bahaya pesisir, seperti gelombang pasang, angin badai, dan erosi. Penelitian ini bertujuan untuk mengkaji valuasi ekonomi jasa pengaturan ekosistem mengarove di wilayah pesisir Kota Pekalongan. Metode yang digunakan adalah survei lapangan untuk mengumpulkan data kondisi eksisting ekosistem mengrove dan wawancara mendalam untuk memperoleh informasi nilai pengganti dari jasa pengaturan ekosistem mangrove. Data yang diperoleh dianalisis secara spasial dan deskriptif. Valuasi ekonomi jasa ekosistem dihitung menggunakan metode pengganti. Hasil penelitian menunjukkan bahwa ekosistem mangrove memiliki jasa pengaturan yang berfungsi melindungi permukiman dan perikanan tambak dari ancaman banjir genangan. Penilaian jasa ekosistem mangrove di wilayah pesisir Kota Pekalongan menunjukkan nilai kehilangan sejumlah 13.664,7 milyar rupiah untuk penggunaan lahan berupa permukiman, sedangkan untuk perikanan tambak sebesar 24.096,275 milyar rupiah.

Abstract

Kulon Progo Government plans to make Pasir mendit and Pasir kadilangu areas agro-tourism of shrimp ponds. The success of a regional development program is usually associated with technical problems and socialization. However, the readiness and ability of the community and the positive perception of the community affect the success of regional development programs. This study aims to assess the socio-economic conditions, determine the public perception of agro-tourism shrimp pond development, and determine the factors that affect public perception of agro-tourism shrimp pond development. Primary data were obtained using a survey method with observation and interview techniques. Descriptive-qualitative analyzed the data through frequency tables, cross tables, and images, while quantitative analysis was carried out based on the regression and multiple linear regression results. The results showed that social and economic conditions are pretty good and rising after the development of shrimp pond farming in Pasir mendit and Pasir kadilangu. In this regard, the public perception of agro-tourism development of shrimp farming areas can be pretty high and agreed on the construction of several considerations. The factors that significantly affect the public perception of agro-tourism products are general knowledge about agro-tourism and income levels.

Abstract

Analysis and prediction of land conversion using spatial-temporal data are essential for environmental monitoring and better land use planning and management. The West Sleman area has the potential to experience land use changes due to anthropogenic factors. This study aimed to determine the spatial-temporal dynamics of land use change in 2012-2022 and predict future land use change using the ANN-CA model for 20 years (2022-2042). Analyzed the spatial-temporal dynamics of land use change based on land use data derived from SPOT imagery, then predicted future land use change with the ANN-CA model using the MOLUSCE plugin on QGIS Desktop 2.18.11. The simulation results showed an accuracy of 86.66% and an overall Kappa value of 83% obtained by comparing the actual data in 2022 with the simulated data on land use change in the same year. The irrigated paddy fields decreased by 6.39% (685.22 ha) due to conversion to settlements. The area of residential buildings increased by 4.65% (498.49 ha) during 2012- 2017. Predictions of land use change in 2022-2042 show that the reduction of irrigated paddy fields will continue, and the number of residential buildings tend to increase.
