Judul: Analisis Cadangan Karbon Sebagai Jasa Lanskap Padang Golf di JABOPUNJUR
Abstrak: Golf courses as man-made landscapes have an important contribution to ecosystem dynamics. Up to now there is still few information of potential carbon stock from golf course vegetation. The presence of vegetations in golf course that able to sequestrate the carbon dioxide were needed for climate change mitigation in order to creating low Carbon as one of the environmental services. This research was conducted at three study sites of golf courses in Jakarta, Bogor, Puncak, and Cianjur (JABOPUNJUR), i.e Cibodas Golf Park, Bogor Golf Club, and the Golf Pantai Indah Kapuk. Those study sites were selected due to the different elevation, Cibodas Golf Park 1330 m above sea level (m asl), Bogor Golf Club 230 m asl, the Golf Pantai Indah Kapuk 3 m asl, respectively. The objectives of this research were: 1) to analyse potential carbon stock in turfgrass, 2) to analyse potential carbon stock of trees and 3) to analyse the structure composition and type of vegetation. There were 42 sampling plot scattered and observed at Cibodas Golf Park, Bogor Golf Club, and the Golf Pantai Indah Kapuk. Carbon stock estimation was calculated by non-destructive sampling method using existing allometric equation. Based on the results turfgrass contributes smaller carbon stock than tree stands on game area, only less than 25 % of the total value from carbon stock in all golf courses. Turfgrass carbon stock increased following by decreasing elevation 7530.26, 9531.36, and 10828.34 kg/ha in Cibodas Golf Park, Bogor Golf Club, and the Golf Pantai Indah Kapuk respectively. On the other side, the highest trees carbon stock was found in Bogor Golf Club 35931.42 kg/ha, following by the Golf Pantai Indah Kapuk 23496.40 kg/ha, and Cibodas Golf Park 10332.97 kg/ha. According to vegetation analysis the level of species diversity was medium at Cibodas Golf Park (H’ = 2.73) and high at Bogor Golf Club (H’ = 4.19), and the Golf Pantai Indah Kapuk (H’ = 3). The difference of carbon stock in turfgrass and trees were strongly influenced by the elevation, age and structure of the trees, as well as basal area of vegetation stands.

Judul: Studi Laju Infiltrasi pada tanah bervegetasi pepohonan dan rumput di Bogor Golf Club dan Cibodas Golf Park
Abstrak: Di negara asalnya (Skotlandia) padang golf biasanya dibangun di atas lahan yang tidak produktif dengan desain yang sederhana. Dalam perjalanan selanjutnya timbul kecenderungan untuk membangun padang golf dengan desain yang lebih artistik. Sehingga padang golf yang mulanya murni dipakai sebagai sarana olah raga, berkembang menjadi sebuah industri yang menguntungkan. R Kecenderungan inilah yang melanda negara-negara di kawasan Asia Pasifik termasuk Indonesia. Menurut data yang terkumpul, di Bogor saja terdapat 15 padang golf (Majalah Progolf, 1995). Akibat perkembangan pembangunan padang golf ini, Bogor sering dijadikan sebagai penyebab, bila terjadi banjir di daerah Jakarta. Tujuan penelitian ini untuk mengetahui tingkat kemampuan lahan bervegetasi rumput dan pepohonan dalam peresapan air ke dalam tanah (infiltrasi) di lapangan golf yang sudah lama dan lapangan golf yang masih baru. Penelitian ini dilakukan di lapangan Bogor Golf Club dan Cibodas Golf Club selama satu bulan (awal Mei Juni 1997). Pengukuran laju infiltrasi dilakukan dengan alat single ring infiltrometer. Laju infiltrasi ini diukur pada tanah yang berpenutupan rumput (fair-way) dan pepohonan sebanyak delapan ulangan dengan lokasi pengukuran ditentukan secara acak....

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.
