Abstract

Cananga odorata and Cymbopogon citratus are two plant species producing inhibitory compounds in their essential oils. In our current research, the potential of their essential oils to inhibit the growth of Staphylococcus aureus and Candida albicans were investigated. MIC (Minimum Inhibitory Concentration) values of mixture of those essential oils with a ratio of 1:1 on those microbes were also assayed. Bioassays were conducted on Nutrient Agar (NA) or Potato Dextrose Agar (PDA) medium added with various ratios of the two plant species essential oils. Medium added with sterile distilled water served as control. The data obtained were analyzed quantitatively with SPSS software for Windows version 22. When significant different at p<0.05 was indicated, the analysis was continued with Duncan's multiple range test. The result showed that all treatment of essential oils applied effectively eliminated the growth of S.aureus. C.albicans appeared to be relatively resistant to 100% of C.odorata essential oil. Elimination of C.albicans was observed when the essential oil of C.odorata was combined with that of C.citratus. When compared to control, all ratios of essential oils treatments were statistically significant (p<0.05). The MIC values of essential oil mixture a ratio of 1:1 on S.aureus and C.albicans were 0,1% and 2,6% respectively. Keywords: essential oil, Cananga odorata, Cymbopogon citratus, Staphylococcus aureus, Candida albicans

Abstract

A study on plants species as resource of food for Bali Starling (Leucopsar rothschildi Stresemann, 1912) was carried out in Ped Village, Nusa Penida, Klungkung Bali, Indonesia between March-April and between August-September, 2006. Explorations methods were conducted in making inventory of plants species and part of plants as food resource. Direct observations were conducted to observe feeding activity of the starling after release. Results of this study showed that 105 plants species have been identified in Ped village. About 30 species (in varied habitus of trees, shrubs, and herbs) acted as food resources for the starling. Part of plants species which had been used as food resources were fruits and seeds. Besides plants as food sources, insects were also available on the studi site (such as grasshopper, ants, caterpillars, butterflies). In addition there were also small reptiles as source of food for the the bird. Plants availability as source of food supports ex-situ conservations of Bali Starling in Ped village.

Abstract

A study on birds has been conducted in Nusa Dua Tourist Resort area, Bali, betweenJanuary, 1999 and January, 2002. In this study, bird species was identified and theirpotentials for ecotourism-bird watching activities were analysed. From the field observationit was found that the site has a potential to be developed as a bird watching site. It can beseen from the diversity of bird species identified there, especially in the lagoon. In Nusa DuaTourist Resort area 83 bird species has been identified which is representing over 27% ofbird species on Bali. About 87% of those were classified as non-migrant species, while therest were migrant. Among those species, 6% were birds which were known to be restrictedtheir distribution to Indonesia. The strategic location of Nusa Dua Tourist Resort area alsoincreases its potential for development of bird watching activities. For development of theseactivities, holistic management approaches need to be implemented, the approaches of whichneed considering a balance between conservation, economic and empowerment of localcommunity objectives.

Abstract

Produk daging olahan adalah salah satu jenis pangan yang mudah mengalami kerusakan. Kerusakan pada produk daging olahan diakibatkan karena adanya pertumbuhan mikroorganisme. Menanggulangi hal tersebut, perusahaan pengolahan daging banyak menambahkan bahan tambahan pangan (BTP) yaitu natrium nitrit (NaNO2). Akumulasi nitrit yang berlebih dalam tubuh dapat menimbulkan efek yang merugikan pada sistem reproduksi. Penelitian oleh Pavlova et al. (2017) menemukan terjadi penurunan berat epididimis dan pengurangan jumlah spermatoa tikus yang diberi paparan NaNO2 tinggi. Rumput laut Eucheuma cottoni mengandung antioksidan yang dapat menetralkan sifat oksidatif yang ditimbulkan oleh NaNO2. Penelitian ini dilakukan untuk mengetahui pengaruh ekstrak rumput laut Eucheuma cottoni terhadap kadar Malondialdehid (MDA) dan spermatozoa pada tikus putih (Rattus norvegicus L.) jantan yang diinduksi NaNO2. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari kontrol negatif (K-), kontrol positif (K+), perlakuan dosis 1 (P1), perlakuan dosis 2 (P2) dan perlakuan 3 (P3). Kontrol negatif (K-) diberikan aquades sedangkan kontrol positif diberikan natrium nitrit dosis 22,5 mg/kg BB. Perlakuan dosis 1,2 dan 3 diberikan metode kombinasi natrium nitrit dan ekstrak rumput laut dosis 150 mg/kgBB/hari (P1), 300 mg/kgBB/hari (P2), dan 450 mg/kgBB/hari (P3). Pemberian perlakuan dilakukan selama 45 hari. Adapun variabel penelitian terdiri dari kadar MDA (Malondialdehid) pada serum dan kualitas spermatozoa meliputi integritas membran, viabilitas, motilitas dan morfologi spermatozoa dari tikus putih jantan. Analisis data dilakukan melalui uji statistik One Way Anova dan dilanjutkan dengan uji Duncan. . Hasil penelitian menunjukkan ekstrak rumput laut dosis 150 mg/kgBB mampu menurunkan kadar MDA (Malondialdehid), meningkatkan motilitas, viabilitas, integritas membran dan morfologi spermatozoa secara signifikan.

Abstract

Karbon tetraklorida (CCl4) merupakan senyawa kimia yang bersifat toksik, namun masih sering digunakan dalam industri bahan pendingin, alat pemadam kebakaran, dan pestisida. Penggunaan CCl4 secara terus menerus dapat memicu terbentuknya radikal bebas sehingga berpotensi merusak organ hati dan ginjal. Tanaman sirsak (Annona muricata L.) salah satu tanaman yang dapat digunakan sebagai obat alternatif karena mengandung senyawa antioksidan yang dapat mencegah pembentukan radikal bebas. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak daun sirsak terhadap gambaran histologi hati dan ginjal mencit (Mus musculus L.) yang diinduksi karbon tetraklorida. Penelitian ini menggunakan Rancangan Acak Lengkap dengan 24 ekor mencit jantan yang dikelompokkan menjadi 4 perlakuan yaitu kontrol negatif (K-) diberi larutan Na-CMC 0,5%, kontrol positif (K+) diinduksi CCl4 0,007 mL/20g BB yang dilarutkan dalam minyak kelapa 0,1 mL, dan dua perlakuan yang diinduksi CCl4 0,007 mL/20g BB serta diberi ekstrak daun sirsak dosis 100 mg/kg BB (P1) dan 200 mg/kg BB (P2). Parameter yang diamati pada histologi hati yaitu degenerasi melemak, degenerasi hidropik, nekrosis, kongesti, serta infiltrasi sel radang. Parameter yang diamati pada histologi ginjal yaitu degenerasi melemak, nekrosis, infiltrasi sel radang, dan pembengkakan glomerulus. Hasil penelitian menunjukkan terjadi penurunan kerusakan yang berbeda nyata (p<0,05) pada P1 dan P2 dibandingkan dengan kontrol positif (K+) pada sayatan histologi hati dan ginjal, sehingga dapat disimpulkan bahwa pemberian ekstrak daun sirsak mampu memperbaiki kerusakan hati dan ginjal setelah diinduksi karbon tetraklorida.
