Abstract

Candida albicans cause opportunistic infection of the oral cavity. Probiotic has health benefits, produces organic acids as anti-C. albicans. The aim of this research was to determine the antifungal activity of commercial fermented milk products against Candida and viability of bacteria in commercial fermented milk products. The antifungal activity was determined using well diffusion method. Viability of lactic acid bacteria was done by plate count method. The results show that commercial fermented milk productshas an activity of anti-C.albicans were shown by irradical zone formed around well containing fermented dairy products. Viability of lactic acid bacteria 107-1010 CFU/mL.

Abstract

Bivalvia merupakan kelompok biota laut sebagai komponen yang penting penyusun ekosistem perairan. Bivalvia merupakan salah satu kelompok organisme invertebrata yang banyak ditemukan dan hidup di daerah pesisir pantai. Pantai Juata Laut Tarakan merupakan salah satu penyebaran Bivalvia yang sangat baik. Meningkatnya eksploitasi Bivalvia menjadi bahan makanan di Kota Tarakan merupakan salah satu faktor yang mengakibatkan penurunan populasi Bivalvia. Tujuan penelitian ini untuk mempelajari struktur komunitas dan pola sebaran Bivalvia di Pantai Juata Laut Tarakan. Metode yang digunakan adalah Belt Transects dengan membuat plot ukuran 1x1 meter. Komunitas Bivalvia di Pantai Juata Laut terdiri dari Anadara granosa dan Polymesoda erosa. Pola sebaran Bivalvia di lokasi tersebut seragam. Pengukuran parameter lingkungan menunjukan komposisi substrat di Pantai Juata laut berupa lumpur berpasir yang memiliki banyak kandungan organik. Kualitas perairan di lokasi ini masih tergolong baik untuk kehidupan Bivalvia.

Abstract

Perubahan iklim telah menjadi persoalan global dan untuk mengatasinya melibatkan berbagai negara dan berbagai disiplin ilmu. Respon yang dilakukan pemerintah Indonesia di dalam menanggapi isu perubahan iklim dan pemanasan global tertuang dalam Peraturan Presiden Nomor 61 Tahun 2011 tentang Rencana Aksi Nasional Penurunan Emisi Gas Rumah Kaca (RAN-GRK) dan Peraturan Presiden No. 71 Tahun 2012 tentang Penyelenggaraan Inventarisasi Emisi GRK Nasional. Inventarisasi GRK di sektor limbah padat tingkat kabupaten ini perlu dilakukan, untuk mengetahui estimasi emisi GRK yang dihasilkan. Penelitian ini bertujuan untuk mengestimasi emisi GRK dari sektor limbah padat di Kabupaten Karangasem, Bali. Pada penelitian ini, menggunakan metode First Order Decay (FOD) yang terdapat dalam IPCC 2006 GL. Dari hasil penelitian diketahui bahwa TPA di kabupaten Karangasem masih bersifat open dumping, yang memiliki Methane Correction Factor (MCF) sebesar 0,8. Jumlah sampah (limbah padat) yang masuk ke TPA tahun 2010 – 2015 mengalami peningkatan dari 37.419 m3 menjadi 43.212 m3. DOC (Degradable Organic Carbon) untuk jenis sampah yang masuk ke TPA (fraksi berat) yaitu sampah makanan 0,38, sampah kertas 0,44, sampah taman 0,49, sampah kain tekstil 0,3, sampah kayu 0,5, sampah kulit/karet 0,47. Berdasarkan hasil perhitungan, estimasi besarnya emisi GRK sektor limbah padat yang dihasilkan di kabupaten Karangasem, dari tahun 2011 sebesar 2.918 ton CO2e dan terus meningkat setiap tahunnya, hingga tahun 2015 emisi yang dihasilkan sebesar 9.153 ton CO2e/tahun.

Abstract

Some benthic minute amphipods have been found at abalones’rearing tank, at Lombok Marine Aquaculture Development Center, Sekotong, West Nusa Tenggara, Indonesia. The minute amphipod community was found along with Gracillaria verrucosa which was harvested from Sekotong fishpond. There is some vigilance that it might be a pest that interferes the production of abalones. This research aims to reveal the type of the minute amphipod at the rearing tank. Morphological characters were examined to identify the Amphipod. Some slide was made to recognise and identify minute apparatus of the Amphipod. A hundred of Amphipod was reared in a small container to see their immediate behavior such as feeding or reproduction or other/s or its product. Some video were used to record for 30” to 60” to see the behavior of Amphipods. Result show that at least four types of Gammaridea present at the abalone culture pond. Some Amphipod was descent to abalone for some time, hop and perch to Gracillaria. Some Amphipods build a nest from pieces of Gracillaria in a tube form. There are two types of nest, firstly, small tube which were attached to the substrate and secondly, bigger tube which were float with the Gracillaria.

Abstract

Ascocentrum miniatum (kebutan orchids) is an orchid species in Indonesia is growing in Java. This orchid is rare (Appendix 2) and difficult to be cultivated. One of the obstacles faced in orchid cultivation A.miniatum because they are prone to fungal pathogens. Of the many fungal pathogens that infect, at most dominating is the fungus Fusarium sp.The aim of the research is to identify the mycorrhizal Rhizoctonia contained in A.miniatum orchids that are resistant to the fungus Fusarium sp. This study is the first stage of the three stages of research for 3 years and performed at the Laboratory of Plant Diseases, Faculty of Agriculture UTP using methods that refers to the research conducted by Bayman dkk. (Otero, 2002) and Barnett & Hunter (1972). Each observation was repeated 5 with each replication contained 5 plants. Results showed that characterization of isolates of Rhizoctonia root mycorrhizal A. miniatum derived from Tawangmangu, Bandungan, Kaliurang, Sleman were not morphologically distinct. Equation characters are in colony color, length and number of the cell nucleus, while the characters are in wide differences in the cells and grouped in Tulasnella. Isolation of Fusarium showed macroconidia formation and pathogenicity tests are positive, and the extent of the disease is highest in the 5th month after the inoculation.

Abstract

Mercury pollution due to gold mining at Pongkor Village can threaten the life of organisms because mercury is toxic. Bioremediation can be considered to reduce mercury concentration in the water. The mercury-resistant bacteria can be isolated from the area and may be developed as mercury bioremediation agents. This study aims to isolate mercury-resistant bacteria, test their resistance to mercury, and conduct protein profile studies after mercury induction. The mercury-resistant bacteria were isolated from soil samples in the Pongkor Village gold mining area and the isolate resistance to HgCl2 was measured based on the Minimum Inhibitory Concentration (MIC) value. The protein profile was analyzed using SDS PAGE gel electrophoresis. The results showed that two of the most resistant bacterial isolates to mercury were HgP1 and HgP2 with MIC value was 575 ppm. The protein profile showed that mercury induced decreased protein synthesis under normal conditions and increased synthesis of one protein suspected to play a role in the mechanism of bacterial resistance to mercury.
