Judul: Keanekaragaman Cendawan Mikoriza Arbuskula (CMA) di Hutan Pantai Ujung Genteng, Sukabumi-Jawa Barat
Abstrak: Indonesia is one of the countries that has a megadiversity of microorganisms and has a large area of coastal forests. However, research on microbial diversity particularly AMF as one of the dominant microbes in a coastal forest ecosystems has not been done extensively. The main objective of this research was to study the diversity and distribution of AMF in coastal forest and to analyse effects of salinity on the fungal and plant community at Coastal Forest Ujung Genteng Cape, Sukabumi - West Java. This research was carried out in two parts: field, green house and laboratorium experimental activities. Field experimental activities were conducted for vegetation analysis, collecting of plant root system, rhizosphere soils from tree and pole phase,. seedling of understorey plants for fungal colonization analysis, isolation and identification of AMF and soil characteristics, include salinity. Green house and laboratorium activities were carried out for isolation, identification and colonization analysis of AMF. Field research location was divided into three zones, first zone was 0 – 70 m distance from coastal area (P), second zone was 71 – 140 m distance from coastal area (T), and third zone was 141 m distance from coastal until forest up to area in the center (H). Twenty three AMF species from 45 plant rizosphere were identified. The fungi belong to 5 species of Acaulospora, 2 species of Gigaspora, 13 species of Glomus, 1 species of Paraglomus and 2 species of Scutellospora. Glomus geosporum was the most dominant AMF in the ecosystem with the value of frequency was 16.49% - 23.67%. Glomus etunicatum, Acaulospora foveata, A. longula, A. scrobiculata, A. tuberculata, and Scutellospora auriglobosa were the AMF that had frequency higher than other species but less than G. geosporum in the field. Results from vegetation analysis indicated that Ujung Genteng Coastal Forest had 68 plant species belonging to 40 families. Dysoxylum parasiticum and Piper cf. baccatum were dominant plants in the ecosystem. The plant community measured at the three zones experimental sites were differed. The similarity index value of the plant community (Is) between coastal P) and center (T) area was 35.42%, between center (T) and forest center (H) was 32.53%, and between coastal edge (P) and forest center (H) was 27.04%. There was no correlation between diversity of plant and diversity of AMF onserved. Diversity of AMF were influenced with all interaction environment factors especially salinity. Two species of AMF had a narrow distribution and found only in a rhizosphere of one plant species . Glomus sp 5. found only in Guettarda speciosa rhizosphere and Glomus sp6. in Salacia sp. rhizosphere. Nineteen species were identified from P zone, 17 species from T zone and 14 species from H zone, with the index diversity values of AMF were 0.73 – 6.64, 0.85 – 4.93 and 1.26 – 4.84, respectively. The salinity at Ujung Genteng Cape was falled in moderate degree with the value of 420 – 1735 μs/cm. The salinity influenced the diversity of AMF and plant community structures. Nineteen species were identified from P zone, 17 species from T zone and 14 species from H zone,

Judul: Keanekaragaman Fungi Mikoriza Arbuskula Berdasarkan Gradien Salinitas di Hutan Pantai Taman Nasional Baluran, Jawa Timur
Abstrak: Mikoriza merupakan simbiosis mutualisme antara fungi dengan perakaran tanaman. Penelitian ini bertujuan untuk mengidentifikasi keberagaman genus kelompok Fungi Mikoriza Arbuskula (FMA) serta hubungannya dengan sifat-sifat tanah, khususnya gradien salinitas di tegakan hutan pantai Perengan Taman Nasional Baluran, Jawa Timur. Prosedur kerja dalam penelitian ini meliputi pengambilan sampel, penghitungan kepadatan spora, isolasi dan identifikasi genus FMA, kuantifikasi kolonisasi FMA, serta penentuan sifat kimia tanah. Kepadatan spora di tanah salin hutan pantai TN Baluran tidak memiliki korelasi dengan gradien salinitas (3‰, 2.5‰, 2‰, 1.5‰ dan 1‰) dan jarak sub plot pengamatan dari garis pantai. Kepadatan spora lebih dipengaruhi oleh faktor genangan dan jenis tanaman sampel. Selain itu gradien salinitas juga tidak memberikan pengaruh terhadap tinggi rendahnya persen kolonisasi FMA. Ditemukan tiga genus FMA (genus Glomus, Acaulospora, dan Gigaspora) dengan genus Glomus sebagai genus yang paling mendominasi. Tanah hutan pantai Taman Nasional Baluran tergolong subur yang ditandai oleh nisbah C/N sedang hingga tinggi. Kandungan P tersedia dalam tanah sampel memberikan pengaruh negatif terhadap kolonisasi mikoriza.

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.
