Judul: Comparison of Indonesia's Natural Rubber Derivative Product Competitiveness with ITRC Member Countries and Determinants of Exports to the United States
Abstrak: Indonesia memiliki potensi penerimaan dari produk turunan karet alam, seperti ban serta pakaian dan aksesori pakaian. Namun, Indonesia belum memiliki spesialisasi ekspor dibandingkan dengan Thailand dan Malaysia. Pasar utama, yaitu Amerika Serikat, juga menjadi tujuan ekspor utama bagi Thailand dan Malaysia, sehingga meningkatkan persaingan. Penelitian ini bertujuan untuk menganalisis daya saing produk turunan karet alam Indonesia dengan negara anggota ITRC lainnya ke Amerika Serikat menggunakan metode Revealed Comparative Advantage (RCA), Export Product Dynamic (EPD), X- Model, dan Indeks Spesialisasi Perdagangan (ISP). Selanjutnya, menganalisis faktor-faktor yang memengaruhi ekspor produk turunan karet alam Indonesia ke Amerika Serikat menggunakan regresi linier berganda. Hasil penelitian menunjukkan bahwa, produk ban Indonesia dan Thailand memiliki potensi pengembangan pasar optimis di Amerika Serikat. Hal tersebut didukung kematangan dan pertumbuhan dari produk ban Thailand dan Indonesia. Sebaliknya, hanya produk pakaian dan aksesori pakaian Indonesia yang memiliki potensi pengembangan pasar optimis di Amerika Serikat. Padahal, ketiga negara sudah didukung oleh kematangan dari produk pakaian dan aksesori pakaian. Faktor-faktor yang signifikan memengaruhi volume ekspor ban Indonesia adalah PDB Amerika Serikat, produksi kendaraan bermotor Amerika Serikat, dan dummy GSP. Adapun faktor-faktor yang signifikan memengaruhi volume ekspor pakaian dan aksesori pakaian Indonesia adalah harga ekspor, PDB Amerika Serikat, dan dummy COVID-19., Indonesia has potential revenue from natural rubber derivative products, such as tires with apparel and clothing accessories. However, Indonesia lacks export specialization compared to Thailand and Malaysia. The main market, the United States, is also the main export destination for Thailand and Malaysia, increasing competition. This study aims to analyze the competitiveness of Indonesia's natural rubber derivative products with other ITRC member countries to the United States using the Revealed Comparative Advantage (RCA), Export Product Dynamic (EPD), X-Model, and Index of Trade Specialization (ISP) methods. Furthermore, it analyzes the factors that influence the export of Indonesian natural rubber derivative products to the United States using multiple linear regression. The results showed that Indonesian and Thailand tire products have optimistic market development potential in the United States. This is supported by the maturity and growth of Thailand and Indonesian tire products. In contrast, only Indonesian apparel and clothing accessories products have optimistic market development potential in the United States. In fact, the three countries are already supported by the maturity of apparel and clothing accessories products. The factors that significantly affect the export volume of Indonesian tires are the GDP of the United States, production of motor vehicles in the United States, and dummy GSP. The factors that significantly affect the export volume of Indonesian apparel and clothing accessories are export prices, GDP of the United States, and dummy COVID-19.

Judul: Comparative Competitiveness of Indonesia and Thailand Natural Rubber Export in the Destination Countries and its Influencing Factors.
Abstrak: Indonesia memiliki areal karet alam terluas di dunia, namun perannya sebagai eksportir karet alam masih di bawah Thailand. Selama 2013-2022, Indonesia dan Thailand memiliki kesamaan beberapa negara tujuan sehingga menimbulkan persaingan ekspor antara kedua negara tersebut. Penelitian ini mengidentifikasi dan membandingkan daya saing ekspor karet alam Indonesia dan Thailand dengan menggunakan metode RCA, EPD, dan X-Model. Identifikasi faktor-faktor yang memengaruhi volume ekspor karet alam Indonesia digunakan regresi data panel. Secara keseluruhan, hasil perhitungan nilai RCA Indonesia 36,55 dan Thailand 29,59 menunjukkan Indonesia memiliki daya saing yang lebih unggul diantaranya di AS, Brazil, India, Jepang, dan Turki, sedangkan Thailand hanya unggul di China dan Korea Selatan. Analisis X-Model menunjukkan karet alam Indonesia memiliki pasar potensial di AS, China, India, Jepang, dan Turki. Sementara Brazil dan Korea Selatan merupakan pasar kurang potensial. Di sisi lain, Thailand memiliki pasar optimis di AS dan Turki, pasar potensial di China, India, Jepang, dan Korea Selatan, pasar kurang potensial di Brazil. Hasil estimasi regresi data panel menunjukkan variabel PDB riil importir, nilai RCA Indonesia, harga karet alam Thailand, dan dummy Covid-19 berpengaruh signifikan terhadap volume ekspor karet alam Indonesia.

Judul: Studi Kasus Diagnosis Pencitraan Gangguan Saluran Pencernaan Atas Anjing Schnauze
Abstrak: The aim of this study was to learn the role of diagnostic imaging to define the diagnose of the upper gastrointestinal tract disorder of the Schnauzer. The information from the owner (anamneses) stated that the dog has been vomiting for a year, sometimes containing blood. There might also be a possibility that it had eaten a corpus alineum. This study case covered physical examination, hematology and blood chemical analysis, radiography, ultrasonography, and endoscopy performed. Physical examination showed weight loss and anorexia. Hematology and blood chemical analysis showed an increase in lymphocyte, haemoglobin (Hb), haemotocrit (Hct), ureum, creatinine, alanin aminotransferase (ALT), and alkaline phosphatase (ALP). Abdominal radiograph showed no abnormality in the abdominal organs. Abdominal ultrasonography showed a hyperechoic mass on the stomach mucosal surface. The mass forms an acoustic shadowing at the ventral. The acoustic shadowing in the stomach may be caused by an accumulation of gas or foreign object such as bone. Endoscopy showed that there was inconsistency of stomach mucosa surface, foamy bile fluid in the stomach, ulcers, and erosion of the stomach mucosal surface. Based on the endoscopy performed, the animal was clearly diagnosed with chronic gastritis accompanied by stomach ulcer and erosion.
