Judul: Requirement Analysis of Agricultural Machinery on Rice Cultivation Based on Physical Workload in Wonogiri Regency
Abstrak: Aktivitas budidaya padi mengharuskan petani sebagai sumber tenaga utama menerima beban kerja. Oleh karena itu, perlu ada peran alsintan untuk meringankan beban kerja petani. Penelitian ini bertujuan untuk menentukan kebutuhan alsintan serta produktivitas energi dari kegiatan budidaya padi. Secara umum, tahapan dalam penelitian ini adalah pengumpulan data, perhitungan data, dan analisis data dengan metode deskriptif. Kebutuhan alsintan pada kondisi ketersediaan petani maksimum adalah sebesar 303 unit transplanter untuk penanaman, 865 unit power weeder untuk penyiangan, dan 41 unit combine harvester untuk pemanenan. Sementara itu untuk kondisi ketersediaan minimum, kebutuhan alsintannya sebesar 481 unit transplanter untuk penanaman, 1.257 unit power weeder untuk penyiangan, 61 unit knapsack power duster untuk pemupukan, dan 164 unit combine harvester untuk pemanenan. Produktivitas energi petani pada ketiga kondisi tersebut masing-masing adalah 0,04 kgGKP/kkal untuk kondisi aktual, 0,05 kgGKP/kkal pada kondisi petani maksimum, dan 0,13 kgGKP/kkal untuk kondisi ketersediaan petani minimum., Rice cultivation activities require farmers as the main source of labor to receive workload. Therefore, there needs to be a role of agricultural machinery to ease the workload of farmers. This research aims to determine the needs of agricultural machinery and energy productivity of rice cultivation activities. In general, the stages in this study are data collection, data calculation, and data analysis with descriptive methods. Agricultural machinery needs in maximum farmer availability conditions are 303 units of transplanter for planting, 865 units of power weeder for weeding, and 41 units of combine harvester for harvesting. Meanwhile, for minimum availability conditions, the needs of agricultural machinery are 481 units of transplanter for planting, 1.257 units of power weeder for weeding, 61 units of knapsack power duster for fertilization, and 164 units of combine harvester for harvesting. Farmers' energy productivity in these three conditions is 0,04 kgGKP/kcal for actual conditions, 0,05 kgGKP/kcal in maximum farmer conditions, and 0,13 kgGKP/kcal for minimum farmer availability conditions.

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.
