Judul: Analysis of Climatic Factors on Brown  Planthopper Attack in Northern Subang
Abstrak: Subang merupakan salah satu sentra produksi padi di Jawa Barat setelah Indramayu dan Karawang. Fluktuasi produksi padi tidak terlepas dari faktor iklim serta serangan hama dan penyakit. Wereng batang coklat (Nilaparvata lugens Stal.) merupakan salah satu hama berbahaya pada tanaman padi karena dapat menularkan virus lain. Pemodelan Climex digunakan untuk mengetahui respon suatu spesies terhadap komponen iklim. Penelitian ini bertujuan menganalisis dampak variabilitas dan perubahan iklim terhadap potensi serangan hama wereng batang coklat di wilayah Subang Utara. Fungsi yang digunakan dalam model Climex adalah compare years dan compare locations. Skenario iklim yang digunakan adalah RCP 4.5 dan RCP 8.5 dengan model CCSM4 dan MIROC5. Hasil penelitian menunjukkan bahwa pada tahun 2011-2020 (baseline) wilayah Subang Utara secara umum memiliki iklim yang sesuai untuk perkembangan wereng batang coklat dengan nilai EI sebesar 62. Adanya variabilitas iklim dapat berdampak pada perkembangan wereng batang coklat. Fenomena El-Nino dapat menurunkan nilai EI menjadi 46 (tahun 2015) dan 43 (tahun 2019). Terjadinya peningkatan suhu, perubahan pola curah hujan, dan naiknya permukaan laut pada tahun 2050-an dapat menurunkan nilai EI menjadi 45 dan 39 (CCSM4) serta 55 dan 50 (MIROC5)., Subang is one of the centers of rice production in West Java after Indramayu and Karawang. Fluctuations in rice production are inseparable from climatic factors and attacks by pests and diseases. Brown planthopper (Nilaparvata lugens Stal.) is a dangerous pest on rice plants because it can transmit other viruses. The Climex model is used to determine the response of a species to climate components. This study aimed to analyze the impact of climate variability and climate change on the potential attack of brown planthoppers in Northern Subang. The functions used in the Climex model are compare years and compare locations. The climate scenarios used are RCP 4.5 and RCP 8.5 with CCSM4 and MIROC5 models. The results showed that in 2011-2020 (baseline) Northern Subang had a climate suitable for the development of brown planthoppers with an EI value of 62. The existence of climate variability can have an impact on the development of brown planthoppers. Phenomenon El-Nino can decrease the EI value to 46 (in 2015) and 43 (in 2019). An increase in temperature, changes in rainfall patterns, and rising sea levels in the 2050s can decrease EI values to 45 and 39 (CCSM4) and 55 and 50 (MIROC5).

Judul: Analisis Fakor Iklim terhadap Penyebaran Hama Wereng Batang Coklat (Nilaparvata lugens Stal.) pada Tanaman Padi di Kabupaten Cianjur
Abstrak: Penelitian ini bertujuan menganalisis pengaruh faktor iklim terhadap penyebaran hama wereng batang coklat (Nilaparvata lugens Stal) pada tanaman padi di Kabupaten Cianjur menggunakan Climex 4.0. Model Climex 4.0 dapat digunakan untuk menganalisis penyebaran hama wereng batang coklat terhadap pengaruh faktor iklim. Pertumbuhan hama wereng batang coklat dapat dipresentasikan menggunakan Indeks Ekoklimatik (EI). EI dihasilkan dari compare location dan compare years untuk membandingkan tingkat kesesuaian hama wereng batang coklat. Tahun 2008-2017 terjadi periode yang sesuai untuk perkembangan hama wereng batang coklat. Pertumbuhan dan perkembangan hama wereng batang coklat (Nilaparvata lugens Stal) sangat sesuai dengan karakteristik iklim di wilayah Kabupaten Cianjur. Adapun nilai indeks ekoklimatik yang diperoleh di Kabupaten Cianjur sebesar 67, hal tersebut menunujukkan bahwa potensi hama wereng batang coklat dapat hidup dan berkembang dengan baik. Tahun 2011 merupakan nilai indeks ekoklimatik tertinggi sebesar 79 dan tahun 2013 merupakan nilai indeks ekoklimatik paling rendah di Cianjur yaitu sebesar 56. Faktor iklim yang sangat mempengaruhi serangan hama wereng batang coklat adalah curah hujan., This study aims to analyze the effect of climatic factors on the spread of the brown planthopper (Nilaparvata lugens Stal) on rice plants in Cianjur Regency using Climex 4.0. The Climex 4.0 model can be used to analyze the spread of the brown plant hopper against the influence of climatic factors. The growth of the brown planthopper can be represented using the Ecoclimatic Index (EI). EI is generated from compare location and compare years to compare the suitability of brown planthopper pests. The year 2008-2017 was an appropriate period for the development of the brown planthopper. The growth and development of the brown plant hopper (Nilaparvata lugens Stal) is in accordance with the climatic characteristics of the Cianjur Regency. The ecoclimatic index value obtained in Cianjur Regency is 67, it shows that the potential for brown planthopper pests can live and develop well. The year 2011 was the highest ecoclimatic index value of 79 and 2013 was the lowest ecoclimatic index value in Cianjur, which was 56. Climatic factors that greatly affect the attack of brown planthopper pests are rainfall.

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.
