Judul: Kajian sifat listrik dan fisik berbagai jenis buah jeruk pada tingkat ketentuannya
Abstrak: Penelitian mengenai mutu jeruk ditinjau dari sifat listrik dan fisiknya belum dilakukan, sejauh ini penentuan kualitas buah jeruk ditentukan dari segi tampilan fisik. Penelitian dilaksanakan di labratorium biofisika dan instrumentasi fisika IPB dengan menggunakan sampel tiga jenis jeruk pasca panen, masing-masing jenis dibedakan kedalam 8 tipe yang dibedakan berdasarkan tingkat ketuanya. Tiap-tiap sampel jeruk utuh dari sari dilakukan karakterisasi fisik (kerapatan, TPT dan pH) dan listriknya (kapasitansi, konduktansi dan loss coefficient).

Judul: Kajian kapasitansi listrik buah jeruk garut dan sifat fisiko kimianya
Abstrak: Garut citrus is the halimark and trademark of Garut regency and as a constituent component of local symbol Garut regency. Altough the benefits of changes a lot, but it can not be useful with good if not pay attention to the quality of citrus fruit itself. Assuring the quality of fruit can be obtained through postharvest handling. As it is we need a study of the characteristics thet lead to quality evaluation, that include the use of electrical Capacitance and physicochemical evaluation. Study of citrus properties base on electrical capacitance measurement have been doned using alternating current signal of law frequency. The electrical capacitance of citrus was investigated on frequency from 50 Hz to 1 MHz. The cell system was used acrilic and electrode plate conductor from Cuprum. The sample of citrus was put at inside of plate, as dielectric material. Hi LCR Tester Hioki 3532-50 was used to measure electrical capacitance of sample. This equipments was provided with the current source which its frequency earn variation. In addition, the study was conducted physico chemical measurements of citrus fruit. Parameters measured in this study is hardness, total dissolved solids, and acidity. Hardness measurement carried out to indicate the level of fruit maturity. Fruit maturity level is characterized by levels of total dissolved solids and acidity increased. This is different from the hardness. The more mature fruit, the smaller hardness. On the electrical properties, experiment result showed that spectrum of electrical capacitance of citrus was exponentially decreasing. Correlation between electrical capacitance at 1 MHz and total dissolved is positive. Correlation between electrical capacitance and acidicy shaw quadratic.

Judul: Case Study of Gallbladder Mucocele and Treatment Used In Small Animals
Abstrak: Gallbladder mucocele (GM) is defined as distention of the gallbladder caused by an inappropriate accumulation or deposition of high concentrations of bile. The purpose of this case study is to study GM conditions in small animals and to report the clinical sign and characteristics of GM through the sonogram interpretation and blood chemistry test evaluation, and studies related to the therapy given and other treatments recommended. A 14-year-old Toy Poodle dog has been diagnosed with severe GM and cholecystitis. No pain signs were shown during the physical examination as asymptomatic is a common characteristic in the early stage of biliary related diseases. In this study Abdominal ultrasonography interpretation and blood chemistry evaluation was conducted in 2021-2022 and analyzed as a secondary data source. Ultrasonography results showed presence of hyperechoic, immobile deposits in gallbladder accompanied by wall thickening and enlarged in size, followed by a significant increase in the enzyme alkaline phosphatase (ALP). This study has summarized mainly the diagnosis and treatments of GM in small animals and suitable alternatives treatments were recommended to encounter the GM conditions in small animals. The effectiveness of combined therapy shows the positive impact on the patient, the condition of GM has been under control.
