Abstract

Research have been carried out to calculate total colony of fungi, determine fungispecies, and the rate spread of the fungi in rhizosphere a cashew plantations (Anacardiumoccidentale L.) at Sukadana Karangasem and Sendang Buleleng for 4 months (October 2012- January 2013). Samples were taken from two different areas in which five point weresampled. Results data were analyzed qualitatively by identifying the species of fungi that is adescription. The quantitative data was taken to calculate total colony of fungi. The researchfound 11 species of fungi taken from two different locations, namely: Aspergilus flavus, A.niger, A. parasiticus, Botrytis cinera, Cladosporium sphaeospermum, Fusariumsporotrichioides, P. brevicompactum, P. citrinum, P. chrysogenum, Rhizopus stolonifer, andSynchephalastrum racemosum. Total fungal colony in Sukadana Karangasem was : 33.6 x103 - 35 x 103 CFU /g, in Sendang Buleleng 22.6 x 103 – 37.6 x 103 CFU/g. Abundance offungi in Sukadana Karangasem is relatively uniform (0.85) and in Sendang Buleleng belongto cluster (1,03).Keywords: Cashew rhizosphere, abudance of fungal species, Karangasem, Buleleng-Bali

Abstract

Has been doing a research about the content of heavy metals (Pb and Cd)in green mustard (Brassica rapa L. subsp. Perviridis Bailey) and carrot (DaucusCarrota L. Var. Sativa Hoffm) that exist in the market of Denpasar city. Purposeof this research was to know the content of Pb and Cd in green mustard andcarrots that exist in traditional markets (Badung and Kreneng market) Denpasarcity that treated by washing and without washing. Content of Pb and Cd in greenmustard and carrots that analyzed by AAS (atomic absorption spectrophotometer).The results of research shows that contents of Pb in green mustard andcarrots that washed and without washed in Kreneng and Badung Market equal to64.71 ± 6.66 ug / g, 69.58 ± 4.61 ug / g, 62.56 ± 6.99 ug / g, 64.96 ± 7:20 ug / g,62.56 ± 6:56 ug / g, 73, 91 ± 2:51 ug / g, 57.17 ± 8:59 ug / g, 59.71 ± 8.93 ug / gdry weight. Content of Cd that washed and without washed equal to SCK 8.81 ±1.68?g / g, 10, 55 ± 1.78 ug / g, 8.09 ± 1.71 ug / g, 9.30 ± 2:01 ug / g, 8.96 ± 1.72ug / g, 10.09 ± 1:09 ug / g, 7.39 ± 1.6 ug / g 5, 8.14 ± 1.71 ug / g dry weight

Abstract

This research aimed to determine the concentration giving Carbon (C) the right to know the waste liquid as solvent Bacterial growth media Phosphate (BPF) performed in the Laboratory of Microbiology, University of Udayana. Experimental research method by adding Dextrosa concentrations varying the liquid waste that has been given out bacterial isolates phosphate solvent the concentration of 0 g (as a control), 0,54 g, 0,77 g and 1,00 g Dextrosa. The results showed the growth of bacteria Solvent Phosphate (BPF) E. gergoviae no significant differences (P <0.05) between the control and treatment of 0,54 g and 1,00 g, 0,77 g where as treatment showed significant differences (P> 0.05) are marked with the number of total number of bacterial colonies of E. gergoviae as many as 2,45 CFU / mL. Keywords : Tofu Liquid Waste, Bacteria Solvent Phosphate (BPF) E. gergoviae, Dextrosa.

Abstract

INTISARI Keberadaan gulma pada tanaman padi akan menyebabkan penurunan produksi apabila gulma tidak dikendalikan secara efektif, karena dapat mempengaruhi pertumbuhan dan menurunkan produksi tanaman pangan. Penelitian ini bertujuan untuk mengetahui keanekaragam jenis gulma yang tumbuh pada tanaman padi (Oryza sativa L.) di Desa Cempaga, Kecamatan Bangli, Kabupaten Bangli, mengetahui jenis gulma yang tumbuh pada tanaman padi (Oryza sativa L.), dan jenis gulma apakah yang dominan pada tanaman padi (Oryza sativa L.). Penelitian ini dilaksanakan di Desa Cempaga Kecamatan Bangli Kabupaten Bangli pada bulan Maret-Mei 2020. Pengumpulan data dilakukan dengan analisis vegetasi menggunakan metode kuadrat dengan cara random menggunakan lotre atau undi dimana pengambilan sampel dilakukan sebanyak tiga kali yaitu pada minggu ke-8, ke-10, dan ke-12 dengan interval waktu pengambilan yaitu sekali dalam 2 minggu sehingga jumlah sampel yang diambil setiap 2 minggu yaitu 15 plot dengan ukuran 1x1m, dan data yang diambil yaitu jenis gulma yang terdapat didalam plot. Hasil pengamatan keberadaan jenis gulma menunjukkan bahwa jenis-jenis gulma yang tumbuh di lokasi penelitian cukup bervariasi, terdapat 781 individu, 12 jenis dan 8 suku, dimana gulma yang paling banyak muncul di plot yaitu tumbuhan Pusut-pusut muncul di 23 plot dan memiliki dominansi relatif yaitu sebesar 49,31%, sedangkan gulma yang paling sedikit muncul yaitu Paku Rawa hanya muncul di satu plot dengan memiliki nilai dominansi relatif yaitu 0,00%. Dimana artinya tumbuhan yang paling berpotensi mengganggu tanaman pokok yaitu tumbuhan Pusut-pusut dengan pola penyebaran yang mengelompok. Nilai INP tertinggi terdapat pada jenis gulma Pusut-pusut dengan nilai sebesar 103.45%. Kata Kunci : Desa Cempaga, Gulma, Padi Sawah
