Abstract

Forest fires are recurring environmental disasters with severe ecological and economic impacts, particularly in regions like West Kalimantan. One of the key indicators used to measure fire intensity is Fire Radiative Power (FRP). Accurate spatial prediction of FRP is essential to support early warning systems and mitigation strategies. This study is a quantitative descriptive research that applies a geostatistical spatial analysis technique, namely Ordinary Kriging interpolation, to predict FRP values in West Kalimantan for July, August, and September 2024. The data were obtained from satellite imagery (VIIRS NOAA-20), including latitude, longitude, and FRP values. Prior to modeling, data were tested for normality and found to follow a normal distribution. The spherical semivariogram model yielded the best fit for July and August with RMSE values of 0.046 and 0.011, respectively, while the Gaussian model was optimal for September (RMSE = 0.007). The results show spatial variation in FRP distribution across different regencies each month, with the highest estimated FRP values recorded in Kapuas Hulu (July: 63.56), Melawi (August: 69.00), and Ketapang (September: 55.27). Most areas demonstrated low fire intensity, as shown by the dominance of green zones on the prediction maps. However, localized red-yellow zones indicate areas with high fire potential, which shifted monthly. This study contributes by demonstrating the application of Ordinary Kriging in forest fire intensity mapping and highlights the importance of choosing an appropriate semivariogram model to enhance predictive accuracy. The resulting FRP prediction maps can serve as a valuable tool for policy planning and targeted fire prevention efforts.

Abstract

Kecamatan Meral Barat menghadapi masalah rendahnya cakupan vaksinasi polio di kalangan anak-anak, yang berpotensi menyebabkan wabah penyakit polio. Tujuan dari pengabdian ini adalah untuk meningkatkan kesadaran masyarakat mengenai pentingnya kesehatan dalam melakukan vaksinasi polio melalui program edukasi dan imunisasi massal. Metode yang digunakan meliputi penyuluhan kesehatan, pelatihan kader posyandu, dan pelaksanaan vaksinasi di sekolah-sekolah setempat. Hasil kegiatan menunjukkan bahwa pengetahuan masyarakat mengenai vaksin polio masih kurang, namun sebagian dari orang tua  memiliki pemahaman yang baik tentang manfaat vaksinasi. Namun, terdapat tantangan seperti skeptisisme terhadap vaksin yang dimana Beberapa orang tua masih ragu untuk mevaksin anak-anak mereka karena berbagai iformasi yang salah tentang vaksin polio ini  yang dipengaruhi oleh berbagai faktor dinamika sosial  sehingga sering terjadi penolakan pada orang tua.Oleh karna itu perlu dilakukan lebih lanjut lagi terkait dengan pemahaman yang mendalam terhadap orang tua dengan melakukan sosialisasi dan edukasi mengenai pemanfaatan vaksin di kalangan sekolah,posyandu,serta pihak-pihak yang terkait

Abstract

Potensi wilayah yang menjadi sasaran pengabdian kepada masyarakat adalah Desa Bundar Kecamatan Karang Baru Kabupaten Aceh Tamiang Provinsi Aceh. Desa ini merupakan daerah yang sangat cocok untuk budidaya ikan air tawar yaitu gurami. Selamai ini para petani budidaya ikan gurami memperoleh bibit ikan gurami didesa tanjung rambut Kabupatden Aceh Tamiang. Para petani budidaya ikan gurami didesa tersebut banyak memproduksi ikan, namun produksi ikan yang dilakukan hanya berupa ikan mentah yang tidak dilakukan olahan sama sekali yang dipasarkan melalui penjualan online. Hal ini menjadi tantangan sendiri untuk membuat olahan produk yang berasal dari ikan sehingga tidak hanya produk ikan mentah saja. Para petani budidaya ikan ini sudah mulai merasakan ekonominya yang hanya berjalan ditempat. Padahal mereka mengharapkan adanya suatu produk kreatifitas dari olahan ikan, antara lain seperti kerupuk ikan, nugget ikan, sosis ikan, dimsus ikan dan berbagai produk olahan ikan lainnya. Kreatifitas produksi yang dilakukan oleh petani nantinya akan meningkatkan pemberdayaan ekonomi pada masyarakat peternak ikan di desa tersebut.

Abstract

Forest fire phenomena exhibit spatial interdependence and temporal dependence, necessitating a spatiotemporal modeling approach to capture the dynamics of fire occurrences. This study models and predicts forest fires using Fire Radiative Power (FRP) as an indicator of fire intensity. Weekly hotspot data from NASA FIRMS, covering the period from July 2024 to August 2025, were analyzed using the Generalized Space-Time Autoregressive (GSTAR) model. The modeling was conducted by considering various forms of spatial partitioning and spatial weight matrices to capture inter-location dependencies. Four spatial partitioning schemes were employed: areal, and grids of 0.50°×0.50°, 1.00°×1.00°, and 1.25°×1.25°; alongside three spatial weight matrices: Queen Contiguity, Rook Contiguity, and Inverse Distance Weighting (IDW). The temporal order and spatial lag were determined using STACF and STPACF plots. From these combinations, 42 GSTAR models were constructed and evaluated through a three-stage process of estimation and residual diagnostic testing. The results indicate that the GSTAR (1;1) model with a 1.00°×1.00° grid and Rook Contiguity and IDW spatial weight matrices is the best-performing model. This model satisfies the white noise assumption and yields a Root Mean Square Error (RMSE) of 6.866, which is the smallest among all evaluated models. The estimates indicate that fires at a given location are influenced by prior conditions and spatial interactions with surrounding areas, suggesting that the GSTAR model supports spatiotemporal monitoring and early warning systems.
