Judul: Crop Simulation Model for Estimating Mung  Bean Productivity at Different Altitude (Case Study: Cilacap Regency and Malang  Regency)
Abstrak: Kacang hijau merupakan tanaman yang dapat tumbuh pada dataran rendah sampai 750 meter di atas permukaan laut. Produktivitas kacang hijau dapat diestimasi nilainya menggunakan model simulasi pertanian yang terdiri dari submodel perkembangan, pertumbuhan, dan neraca air dengan variabel iklim sebagai input model. Penelitian ini bertujuan untuk menyusun model simulasi perkembangan, pertumbuhan, dan neraca air tanaman kacang hijau untuk memperkirakan produktivitas dan kebutuhan air, serta menjelaskan pengaruh perubahan suhu terhadap produktivitas tanaman kacang hijau. Produktivitas kacang hijau hasil keluaran model memiliki perbedaan nilai dengan hasil observasi dengan nilai koefisien determinasi sebesar 0,99 di Kabupaten Cilacap dan Kabupaten Malang, sedangkan nilai galatnya sebesar 1,04 % di Kabupaten Cilacap dan 2,83 % di Kabupaten Malang. Nilai kebutuhan air di Kabupaten Cilacap sebesar 220 - 363 mm dalam sekali masa tanam dan Kabupaten Malang sebesar 306 - 454 mm dalam sekali masa tanam. Peningkatan suhu sebesar 1 °C menyebabkan penurunan sebesar 2,79-17,4 % di Kabupaten Cilacap dan 1,86- 22,51 % di Kabupaten Malang., Mung bean is a plant that can grow in the lowlands up to 750 meters above sea level. Mung bean productivity can be estimated using a crop simulation model consisting of sub-models of development, growth, and water balance with climate variables as model inputs. This study aims to develop a simulation model for the development, growth, and water balance of mung bean plants to estimate productivity and water demand, and explain the effect of temperature changes on mung bean productivity. The mung bean productivity from the model output has a different value with the observation results with a coefficient of determination of 0.99 in Cilacap Regency and Malang Regency, while the error value is 1,04% in Cilacap Regency and 2,83% in Malang Regency. The value of water requitm in Cilacap Regency is 220 - 363 mm in one planting season and Malang Regency is 306 - 454 mm in one planting season. An increase in temperature of 1 °C causes a decrease of 2,79-17,4% in Cilacap Regency and 1,86-22,51% in Malang Regency.

Judul: Development of an Agricultural Simulation Model to Predict Green Mung Beans Productivity in the Highlands
Abstrak: Produktivitas tanaman kacang hijau terus mengalami penurunan dari tahun ke tahun, salah satu penyebabnya adalah kurangnya areal penanaman. Kacang hijau dapat tumbuh dengan baik di dataran rendah sampai menengah pada ketinggian 500 mdpl. Penelitian ini bertujuan untuk mengetahui produktivitas tanaman kacang hijau pada dataran tinggi dan melakukan validasi terhadap hasil produktivitas keluaran model simulasi tanaman. Pengambilan data variabel iklim dilakukan dengan Menggunakan Automatic Weather Station (AWS), pengambilan data parameter tanah menggunakan metode Ring Sampel Test, dan pengambilan data parameter tanaman dilakukan dengan menggunakan metode destruktif. Wilayah kajian memiliki rata rata suhu udara sebesar 210C, kelembapan udara 91%, kecepatan angin 1,5 m/s, dan total curah hujan sebesar 881 mm. Kalibrasi dan validasi model dilakukan untuk melihat keakuratan hasil model terhadap hasil observasi. Hasil kalibrasi model menunjukan produktivitas tanaman kacang hijau keluaran model pada dataran tinggi sebesar 423 kg/ha sedangkan produktivitas tanaman kacang hijau hasil observasi sebesar 414 kg/ha. Hasil kalibrasi model memiliki akurasi yang tinggi yaitu 97% dan galat yang rendah yaitu 3%. Hasil validasi model menunjukan produktivitas keluaran model sebesar 570 kg/ha dan produktivitas observasi sebesar 870 kg/ha, dengan nilai galat sebesar 42% dan akurasi sebesar 58%., Mung bean crop productivity continues to decline yearly, one of the causes is the lack of planting areas. Mung beans can grow well in the low to medium plains at 500 meters above sea level. This study aims to determine the productivity of mung bean plants in the highlands and validate the productivity results of the plant simulation model output. Data collection of climatic variables was carried out using the Automatic Weather Station (AWS), data collection of soil parameters using the Ring Sample Test method, and plant parameters collected using the destructive process. The study area has an average air temperature of 210C, air humidity of 91%, wind speed of 1.5 m/s, and total rainfall of 881 mm. Model calibration and validation were conducted to see the accuracy of the model results against the observations. The model calibration results showed that the productivity of mung bean plants produced by the model in the highlands was 423 kg/ha, while the productivity of mung bean plants observed was 414 kg/ha. The model calibration results have a high accuracy of 97% and a low error of 3%. Model validation results show model output productivity of 570 kg/ha and observed productivity of 870 kg/ha, with an error value of 42% and an accuracy of 58%.

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.
