Judul: Analysis of Land Cover Change and Its Impact on Near Surface Temperature in Jambi City Using The WRF Model
Abstrak: Studi ini bertujuan mengidentifikasi dan menganalisis variasi suhu udara permukaan akibat perubahan tutupan lahan di Kota Jambi menggunakan model WRF. Klasifikasi tutupan lahan di Kota Jambi menggunakan data MODIS MCD12Q1. Klasifikasi tersebut terdiri atas sepuluh kategori tutupan lahan berdasarkan skema IGBP, dengan evergreen broadleaf forest dan woody savannas menjadi tipe tutupan lahan dominan. Wilayah Jambi memiliki pola curah hujan ekuatorial, ditandai dengan adanya dua puncak musim hujan. Curah hujan bulanan tertinggi sebesar 256 mm tercatat pada bulan Desember, sedangkan yang terendah adalah 102 mm pada bulan Juni. Musim kemarau berlangsung dari bulan Juni hingga September, dengan curah hujan bulanan di bawah 150 mm. Validasi hasil suhu udara model WRF menggunakan data pengamatan suhu harian rata-rata dari Stasiun Meteorologi Sultan Thaha. Perbandingan antara suhu udara rata-rata harian dari hasil model dan pengamatan di Stasiun Meteorologi Sultan Thaha menunjukkan perbedaan yang relatif tidak signifikan, dengan variasi berkisar antara 0,06 hingga 2,55 °C. Secara umum, nilai p hasil pengujian lebih rendah dari tingkat signifikansi (α = 0,05) menunjukkan bukti kuat adanya perbedaan signifikan secara statistik dalam suhu udara rata-rata harian antara tahun 2003 dan 2021 baik untuk bulan Juni maupun Desember., The study aims to identify and analyze the impact of near-surface air temperature variation due to land cover changes in Jambi City using the WRF model. Land cover classification of Jambi City using MODIS MCD12Q1 data. The classification consists of ten land cover categories based on the IGBP scheme, with evergreen broadleaf forest and woody savannas being the dominant land cover types. The Jambi region has an equatorial rainfall pattern, characterized by two peaks in the rainy season. The highest monthly rainfall of 256 mm is recorded in December, while the lowest is 102 mm in June. The dry season lasts from June to September, with monthly rainfall below 150 mm. Validation of WRF model air temperature results using average daily temperature observation data from Sultan Thaha Meteorological Station. Comparison between daily average air temperature from model results and observations at Sultan Thaha Meteorological Station showed relatively insignificant differences, with variations ranging from 0.06 to 2.55 °C. In general, the p values of the test results are lower than the significance level (α = 0.05) indicating strong evidence of statistically significant differences in daily average air temperature between 2003 and 2021 for both June and December.

Judul: The Dynamics of Land Cover and Surface Temperature Changes in The Lembang Tourism Area and Its Surroundings
Abstrak: Perubahan pola penggunaan lahan terus terjadi terutama pada daerah bervegatasi dan daerah terbangun. Pembangunan alih fungsi lahan sangat mempengaruhi dari fungsi kawasan penelitian terhadap daerah disekitarnya. Penggunaan Teknik pengideraan jarak jauh dan sistem informasi geografis (SIG) mempermudah proses monitoring dan pengawasan dengan memanfaatkan gelombang panjang yang dipancarkan matahari. Penelitian dilakukan untuk mengetahui perubahan tutupan lahan, suhu permukaan dan analisis pengaruh perubahan tutupan lahan terhadap suhu permukaan selama 29 tahun. Tutupan lahan menggunakan metode maximum likelihood classification (MLC) diklasifikasi menjadi 6 kelas tutupan lahan. Kelas tutupan lahan hutan mengalami penurunan luas sebesar 457,12 ha sedangkan pemukiman mengalami peningkatan sebesar 703,92 ha. Hasil uji akurasi menghasilkan nilai overall accuracy yang dihasilkan sebesar 96.6% atau almost perfect agreement. Suhu permukaan dilakukan pada bulan juli pada setiap tahun pengamatan mengalami peningkatan sebesar 6,3 0C. Hasil analisis menunjukan perubahan tutupan lahan mempengaruhi suhu permukaan di kawasan. Kelas tutupan lahan yang mengalami peningkatan suhu tertinggi adalah pemukiman dan lahan terbuka. Selain disebabkan oleh perubahan tutupan lahan, juga terpengaruhi oleh perubahan iklim global., Changes in land use patterns continue to occur, especially in vegetated areas and built-up areas. The development of land conversion greatly influences the function of the research area in the surrounding area. The use of remote sensing techniques and geographic information systems (GIS) facilitates the monitoring and surveillance process by utilizing the long waves emitted by the sun. The research was conducted to determine changes in land cover, and surface temperature and analysis of the effect of changes in land cover on surface temperature for 29 years. Land cover using the maximum likelihood classification (MLC) method is classified into 6 land cover classes. The forest land cover class decreased by 457.12 ha while settlements increased by 703.92 ha. The results of the accuracy produce an overall accuracy value of 96.6% or almost perfect agreement. The surface temperature is carried out in July in which each observation year has increased by 6.3 0C. The results of the analysis show that changes in land cover affect the surface temperature in the area. The land cover classes that experienced the highest increase in temperature were settlements and open land. Besides being caused by changes in land cover, it is also affected by global climate change.

Judul: Studi Kasus Liver Neoplasia pada Anjing Shih Tzu
Abstrak: Liver neoplasia is the excessive and uncontrolled replication of hepatocytes that forms nodules visible in ultrasonography. The purpose of this study is to study and discuss the characteristic, diagnosis and treatment of liver neoplasm through the interpretation of ultrasonography and hematology in a Shih Tzu dog. Ultrasonography is conducted with a Chison Q8 ultrasound machine with a 5 to 7 MHz frequency convex probe on lateral recumbency. The blood cells, liver enzymes and nodules sizes were the main parameters in this study. The results in the period of three years from 2021 to 2023 were interpreted and supported with secondary data sources. The Shih Tzu dog is 14 years old in the year 2023 with a body weight of 5.21kg. No obvious clinical signs were observed during previous examinations. However, lethargy, vomiting and anorexia were recorded in its latest examination. Thrombocytosis, granulocytosis, high liver enzymes and hypoglycemia, which are some of the neoplastic clinical manifestations were also presented by this patient. Besides, liver neoplasm, spleen neoplasm and biliary sludge were the sonogram findings of this patient. The liver and spleen neoplasm was observed stable, while the biliary sludge volume fluctuated. The treatment strategy recorded is Ondansetron, Samylin®, Ornipural and Ursodeoxycholic acid.
