Abstract

Penelitian ini bertujuan unuk melihat gambaran histologi arteri dorsal penis tikus wistar (Rattus novergicus) yang dibuat hiperlipidemia dengan induksi pakan tinggi lemak yang dilihat dari segi diameter lumen serta ketebalan dinding endotelium arteri. Hiperlipidemia merupakan faktor resiko ateriosklerosis pada arteri penis penyebab disfungsi ereksi pada pria. Penelitian ini menggunakan rancangan randomized posttest only control goup design. Sampel tikus wistar jantan dewasa umur 3-4 bulan dengan kisaran berat badan 150 - 200 gram, berjumlah 10 ekor. Sebelum perlakuan, dilakukan adaptasi selama 7 hari. Setelah itu tikus sampel pada kelompok perlakuan dibuat hiperlidemia dengan diberi lemak babi selama 50 hari. Kemudian dilakukan pembedahan untuk preparat histopatologi pada posttest. Untuk mengetahui perbedaan ketebalan endotelium dan diameter lumen arteri pada kedua kelompok maka digunakan uji independent t-test. Hasil penelitian menunjukkan bahwa diameter lumen dan tebal endotelium arteri dorsal penis tikus wistar antara kelompok perlakuan lebih rendah dengan kelompok kontrol. Perbedaan yang terjadi bermakna secara statistik (p<0,05). Jadi dapat disimpulkan bahwa pemberian makanan tinggi lemak (hiperlipidemia) menurunkan diameter lumen serta ketebalan endotelium arteri dorsal penis. Kata Kunci: Arteri dorsal, Pakan Tinggi Lemak, Tikus Wistar

Abstract

Carbapenem Resistant Enterobacteriaceae (CRE) is a group of Enterobacteriaceae resistant to Carbapenem antibiotics (Imipenem, Ertapenem, Meropenem, Doripenem). One species of Enterobacteriaceae frequently showing resistant characteristic to Carbapenem is Klebsiella pneumoniae. Early detection methods on the CRE existence (phenotypically or genetically) are urgently needed. The methods should be able to detect carbapenemases or genes encoding these types of enzymes. In the recent years, phenotypic characteristics can be done by applying methods, such as Modified Hodge Test (MHT), Carba Nordmann-Poirel (Carba NP), or Modified Carbapenem Inactivation Method (MCIM). To detect the presence of genes encoding production of carbapenemases, Polymerase Chain Reaction (PCR) is the most reliable method available in the recent years. Keywords: Carbapenem Resistant Enterobacteriaceae (CRE), Phenotype, Genothype, Modified Carbapenem Inactivation Method (MCIM), Modified Hodge Test (MHT), Carba Nordmann-Poirel, Polymerase Chain Reaction (PCR).

Abstract

Sandalwood (Santalum album L.) is a endemic spesies of the Lesser Sunda Island (NTT), grows in deciduous forest or in private traditional plantation for centuries. Study aimed to evaluated profile dynamic structure population of sandalwood in forest and plantation in the district of South Central Timor (TTS) and North Central Timor (TTU). Population structure analysis was held by purposive sampling in eight sites comprised 87 plots. Plots size were 20x20 m2 (trees), 10x10 m2 (poles), 5x5 m2 (saplings), 2x2 m2 (seedlings). Variables observed in each plot were included density, stem diameter, height of free trunk (TBBC), height trees and saplings, crown quality and coverage. Data were analyzed by qualitative descriptively and multivariate statistics. Results showed that population structure of sandalwood varied spatially in all study sites in two district, especially density of seedlings and saplings in plantations and forests. Sandalwood trees density ranges from 0-23 ind.ha-1, poles phase 80-322 ind.ha-1, saplings phase 60-1,289 ind.ha-1, while the seedlings phase is very dominant 2,000-27,813 ind.ha-1. Higher saplings and poles density were found in two sites of TTU plantation and forest or a TTS forest. Farmer in two districts successfully cultivated sandalwood in plantation shown by similar growth quality with those of forest trees.

Abstract

This research was aimed to obtain the kind of proper natural food and the optimum dose of feeding in order to support the rearing of banggai cardinal fish breeding. This research used completely randomized design and was conducted during September to December 2016. The kinds of natural food examined were trash fish, abalone (Haliotis glabra), and squid (Loligo pealei). After we found the most preferable food, the examination upon its dose was conducted under 10%, 20% and 30% of the fish weight. The 45 fish sampel have average length and weight of 3 cm and 0,47 g, respectively. Fish were reared in aquarium 95 cm x 45 cm x 35 cm. The foods were given three times a day. The research results show that abalone was mostly consumed compared to other two foods about 0,11 g/fish a day. The result of examining dose showed that the highest rate of fish growth was found under the dose of 30% which resulted 2,07 cm in length, 0,34 g in weight and the dose of 20% which resulted 2,07 cm in length, 0,33 g in weight. The statistical test result showed that the treatment under the dose of 30% and 20% was not significantly different (P>0,05). Base on this study, it can be concluded that abalone is the proper natural food that supports the rearing of banggai cardinal fish with optimum dose of 20 % of fish weight per day. Keywords: Banggai cardinal fish, Natural Feed, Lini Aquaculture Training Center.
