Judul: Pendugaan potensi serapan karbon pada tegakan pinus di KPH Cianjur Perum Perhutani Unit III Jawa Barat dan Banten
Abstrak: Peranan hutan sebagai penyerap karbon mulai menjadi sorotan pada saat bumi dihadapkan pada persoalan efek rumah kaca, berupa kecenderungan peningkatan suhu udara atau biasa disebut sebagai pemanasan global. Penyebab terjadinya pemanasan global ini adalah adanya peningkatan konsentrasi Gas Rumah Kaca (GRK) di atmosfer dimana peningkatan ini menyebabkan keseimbangan radiasi berubah sehingga suhu bumi meningkat. GRK yang penting diperhitungkan dalam pemanasan global adalah karbon dioksida (CO2) karena memiliki kontribusi lebih dari 55% terhadap kandungan GRK. Peningkatan konsentrasi GRK saat ini berada pada laju yang mengkhawatirkan sehingga GRK harus segera dikendalikan. Upaya mengatasi pemanasan global dapat dilakukan dengan cara mengurangi emisi karbon di atmosfer. Penelitian ini bertujuan untuk mengetahui pendugaan potensi simpanan karbon pada tegakan hutan Pinus pada umur tertentu di KPH Cianjur. Penelitian ini menggunakan metode destruktif yang dilakukan terhadap pohon contoh dari populasi tegakan pada umur tertentu. Pohon contoh diukur dan ditimbang biomassanya, setelah itu dibuat suatu persamaan untuk menduga potensi karbon yang terdapat pada wilayah penelitian berdasarkan dari besar diameter pohon. Hasil penelitian menunjukan bahwa serapan karbon pohon pada masing-masing umur berbeda-beda, yaitu pada umur 1, 2, 3, 4, 5, dan 9 tahun berturut-turut sebesar 98,58 kg/ha; 533,80 kg/ha; 3.200 kg/ha; 4.704,73 kg/ha; 13.643,08 kg/ha; dan 11.947,52 kg/ha. Terdapat penurunan pada umur 9 tahun karena adanya penjarangan pada umur tersebut. Serapan karbon pada serasah pada tegakan umur 1, 2, 3, 4, 5, dan 9 tahun berturut-turut sebesar 66,48 kg/ha, 145,08 kg/ha, 301,99 kg/ha, 166,67 kg/ha, 313,95 kg/ha, 420,06 kg/ha. Potensi serapan karbon serasah cenderung stabil pada setiap umur. Peningkatan dugaan potensi serapan karbon terlihat seiring dengan meningkatnya umur tegakan pinus di BKPH Cianjur.

Judul: Pendugaan potensi simpanan karbon pada tegakan Pinus (Pinus merkusii Jungh. et de Vriese) di KPH Cianjur, Perum Perhutani Unit III Jawa Barat dan Banten
Abstrak: Global warming is one of the major environmental issues that currently concern to the various parties. Because of global warming, increasing in average temperature of earth's sea and land caused by industrial activity and reduction of forest cover due to deforestation, especially lately. Based on these evolving issues and considering the importance of the role of forests in absorbing carbon from the air and store it in forest biomass, it is necessary a lot of research that could encourage the continued development of carbon in biomass. One important aspect of research is to know the potential of carbon stored in the stands of pine. The experiment was conducted in KPH Cianjur, Perum Perhutani Unit III West Java and Banten in April 2010 to May 2010. Materials used in this research were planting stands of pine in 1994 on square 27A RPH West Hanjawar BKPH South Sukanagara and planted stands of Pine year 1995 on square 48I RPH East Hanjawar BKPH North Sukanagara in KPH Cianjur, Perum Perhutani Unit III West Java and Banten. The tools used in this study include scales, digital scales, ovens, machete, newsprint, chalk, plastic bags, plastic rope, stationery, tally sheets, calculator, tape measure, camera, and software SAS. In the area of stands are made each 5 plots with a size of 20 m x 20 m to measure the trees and also made small plots measuring 2 m x 2 m by 4 pieces located at each corner for analysis and retrieval of vegetation and litter. Results obtained from these data are processed through the approach of biomass which is then converted to carbon savings in ton/ha. To know the factors that influence the use of carbon deposits by using ANOVA analysis and Duncan Multiple Range Test (DMRT). The results showed that the potential of carbon storage on plots planted in 1995 is 77,1580 ton/ha greater than the potential carbon storage on plots planted in 1994 which only amounted to 64,6372 ton/ha. The test results using ANOVA statistical analysis showed the value of R-Sq = 96,01% and significant level 5%, there is a difference between the carbon potential on one of the object variabel (tree, manure, below plant) which is found on the stands of pine planted in 1994 and stands pine planting in 1995, where the variable is a tree. There needs to be further research on the estimation of carbon stock potential using a different method of harvesting method with the same kind of pine stands.

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.
