Judul: Radiasi Spektral beberapa Jenis Daun Pohon di Kampus IPB Darmaga
Abstrak: Setiap kegiatan antropogenik yang menggunakan bahan bakar fosil akan menghasilkan polutan berupa gas-gas rumah kaca. Gas CO2 beserta gas-gas rumah kaca lain meningkatkan suhu udara perkotaan melalui efek rumah kaca. Tujuan dilakukannya penelitian ini adalah untuk mengukur nilai radiasi spektral beberapa jenis daun pohon di Kampus IPB Darmaga dan menentukan jenis pohon yang efektif dalam menyerap CO2. Data yang terkumpul dianalisis secara statistik yang diurutkan berdasarkan nilai radiasi spektral. Sementara itu pengelompokan spesies dalam menyerap CO2 dilakukan berdasarkan sebaran normal dari data. Nilai radiasi spektral berbanding terbalik dengan kemampuan tumbuhan menyerap CO2. Jenis pohon yang tergolong memiliki kemampuan tinggi dalam menyerap CO2 adalah asam jawa, saga, trembesi, dan kapuk sedangkan jenis daun pohon yang tergolong memiliki kemampuan rendah dalam menyerap CO2 adalah sirsak, angsana, Acacia mangium, and kenanga, sisanya tergolong memiliki kemampuan sedang.

Abstrak: The increase of temperature in urban area is indirectly caused by the increase of Carbon Dioxide (CO2) concentration in the atmosphere. The increase is caused by land cover alteration and high amount of human activities which uses fossil fuel. The existence of urban forest is one of the ways to coupe the increase of CO2 concentration in the urban atmosphere. Through photosynthesis process, CO2 gas is absorbed by various plants in urban forest and afterwards being released as Oxygen (O2). To control or reduce the concentration of CO2 effectively, in the establishment of urban forest, selection of plants which have maximum ability in reducing CO2 concentration needs to be done. The objectives of this research are to obtain data CO2 sink ability of 15 urban forest plant species in Bogor Agricultural University and to obtain data about the plant species that has the effective CO2 sink ability among the plants which are measured. The measuring of CO2 sink ability was conducted using carbohydrate method. CO2 mass is obtained by converting carbohydrate mass produced in photosynthesis. Other data taken include leaf area and the number of leaves. The higher the leaf area, the higher CO2 sink ability of a leaf. The higher number leaf of a tree, the higher CO2 sink in a tree. The CO2 sink ability of 15 plant species in cm2 of leaf area are (g CO2/cm2/hour): M. caesia 3,793 x 10-4; D. indica 2,180 x 10-4; B. racemosa 1,600 x 10-4; S. campanulata 1,249 x 10-4; M. champaca 1,176 x 10-4; S. malacense 0,820 x 10-4 ; B. capitella 0,805 x 10-4; C. cauliflora 0,734 x 10-4; V. pubescens 0,669 x 10-4; C. inophyllum 0,629 x 10-4 ; M. ferrea 0,479 x 10-4; A. moluccana 0,357 x 10-4; A. dammara 0,268 x 10-4-; and G. dulcis 0,089 x 10-4. The CO2 sink ability of 15 plant species in urban forest in order from the highest are D. indica, M. caesia, S. campanulata, C. inophyllum, B. racemosa, V. pubescens, M. ferrea, C. cauliflora,B. capitella, G. dulcis, M. champaca, S. malacense, A. moluccana, and A. dammara.

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.
