Judul: Sifat Anti Rayap Zat Ekstraktif Kayu Teras Mindi (Melia azedarach Linn.) terhadap Serangan Rayap Tanah Coptotermes curvignathus Holmgren
Abstrak: Melia azedarach yang dikenal dengan nama mindi merupakan salah satu tanaman cepat tumbuh yang berpotensi sebagai insektisida nabati. Tujuan penelitian ini adalah untuk menentukan kandungan zat ekstraktif kayu teras mindi, menentukan sifat bioaktivitas zat ekstraktif kayu teras mindi terhadap rayap tanah, dan mengidentifikasi senyawa kimia zat ekstraktif kayu teras mindi. Perlakuan pada penelitian ini terdiri dari perlakuan kontrol, dan pemberian ekstrak fraksi n-heksan, etil eter, etil asetat, dan residu dengan konsentrasi 2, 4, 6, 8, dan 10%, serta identifikasi senyawa kimia zat ekstraktif menggunakan pyr-GCMS. Hasil penelitian menunjukkan bahwa kandungan zat esktraktif kayu teras mindi yang diperoleh sebesar 0.74%, dan menunjukkan adanya sifat bioaktivitas anti rayap tertinggi pada fraksi n-heksan konsentrasi 8% dan 10% dengan mortalitas rayap tertinggi yaitu 100%, dan kehilangan berat kertas terendah sebesar 13.50% dan 12.29%. Senyawa kimia dominan yang terkandung dalam zat ekstraktif kayu teras mindi yaitu asam palmitat, olealdehida, stearil aldehida, dan androstenediol.

Abstrak: Chinaberry, M. azedarach, is one of the species of Meliaceae family recognized having insecticide properties. The objective of this research was to determine extractive substances percentage of chinaberry, and to test the antitermite activities against subterranean termites C. curvignathus Holmgren, as well as to analyze chemical substances extract quantitatively through Pyr-GC-MS. The extraction of chinaberry leaves used multilevel fractionation method where in there are four types of fractions obtained, namely n-hexane, ethyl ether, ethyl acetate, and the residue. Each fraction was made at concentration of 2%, 4%, 6%, 8%, and 10% for the termites test. The result showed the percentage of chinaberry leaves extractives was 10.53%. Ethyl ether fraction had the highest termite activity at all concentrations based on mortality and weight loss. At concentration of 8% and 10%, ethyl ether fraction resulted in mortality of up to 100% with a weight loss of 0.63% and 5.37%. Based on the analysis of GC-MS pyrolysis, leaves extract which was soluble in ethyl ether contained five compounds with the highest concentration, namely cinnamic acid, benzoic acid, benzenepropanoic acid, palmitic acid, and phytol

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.
