Abstract

AbstrakArea konservasi ex situ, Ecopark Cibinong Science Center-Botanic Gardens (CSC-BG), membutuhkan strategi pemeliharaan tanaman koleksi yang tepat untuk mendukung kesehatan dan keberlanjutan koleksinya. Serangan benalu atau tumbuhan parasit tidak hanya dapat merusak estetika, namun juga menghambat pertumbuhan dan perkembangan, bahkan membunuh tanaman koleksi. Penelitian ini bertujuan untuk mengetahui keanekaragaman jenis benalu dan distribusi spasial dari sebaran benalu di Ecopark CSC-BG. Pengumpulan spesimen dan data, meliputi jenis dan jumlah benalu, jenis dan kondisi inang, habitat menggunakan metode jelajah di seluruh area ini. Ditemukan empat jenis benalu dari suku Lorantaceae, yaitu Dendrophthoe pentandra (L.) Miq., Scurrula atropurpurea (Blume) Danser, Macrosolen cochinchinensis (Lour.) Tiegh., dan Dendrophthoe sp. Benalu tersebut tersebar di bioregion Blok 1, Jawa-Bali, Kalimantan, Sumatra, dan Papua. Beberapa faktor ekofisiologi yang disarankan untuk diperhatikan dalam distribusi benalu adalah tinggi inang, ekspos cahaya pada tajuk bagian atas inang, kepadatan tanaman koleksi, keterbukaan atau ekspos cahaya matahari pada habitat. Indeks keanekaragaman (H’) dan indeks kemerataan (E’) benalu yang ditemukan menunjukkan H’ = 1,29 dan E’ = 0,93. Hasil analisis pola spasial, keberadaan benalu relatif merata di seluruh bagian Ecopark CSC-BG, dengan keragaman jenis tertinggi berada di bioregion Jawa-Bali, Sumatra, dan Kalimantan. Kesimpulan penelitian ini 4 jenis benalu yang ditemukan di Ecopark CSC-BG dengan nilai indeks keanekaragaman jenis benalu tergolong sedang dengan pola sebaran merata.AbstractThe relevant information of existing mistletoes or parasitic plants in Ecopark-Cibinong Science Center & Botanic Gardens is needed to support the plant collection maintenance strategy. The attack of mistletoes does not only inflict the aesthetic values of the collection but also inhibits the growth and possibly kills the whole plant. This research aimed to know the mistletoes species diversity and spatial distribution in the garden. The exploration method was used to collect specimens and data, included the species and number of mistletoes, the host and its condition, habitat and location. Four species of Loranthaceae attacked the plant collection in bioregion Blok 1, Jawa-Bali, Sumatra dan Kalimantan. They were Dendrophthoe pentandra (L.) Miq., Scurrula atropurpurea (Blume) Danser, Macrosolen cochinchinensis (Lour.) Tiegh. and Dendrophthoe sp.. Some of the recommended ecophysiological factors to consider in the distribution of mistletoes in Ecopark, CSC-BG were host height, light exposure to the upper canopy of the host, plant collection density, openness, or exposure to sunlight in the habitat. The diversity index (H ') and evenness index (E') of mistletoes found in Ecopark CSC-BG were 1.29 and 0.93, respectively. Based on the results of spatial pattern analysis, the presence of mistletoes was relatively evenly distributed throughout the garden, with the highest species diversity found in the Java-Bali, Sumatra, and Kalimantan Bioregions. This study concludes that there were 4 species of mistletoes found in Ecopark CSC-BG with a moderate diversity index and an even distribution pattern.

Abstract

AbstrakKKeterlibatan biofilm pada infeksi kronis dan pada permukaan peralatan medis selalu menjadi wacana penting bagi kesehatan umum di dunia. Biofilm bakteri berkaitan dengan tingkat resistensi terhadap antibiotik yang menjadikan infeksi sulit untuk diobati. Untuk mengatasi masalah ini, pengendalian yang efektif perlu diimplementasikan, seperti penerapan senyawa antibiofilm. Beberapa tahun terakhir, lingkungan akuatik menjadi salah satu sumber potensi penghasil senyawa bioaktif, termasuk senyawa antibiofilm. Tujuan dari penelitian ini yaitu menapis dan mengkarakterisasi bakteri asal air terjun dan laut yang diperoleh dari beberapa lokasi di Indonesia, sebagai penghasil aktivitas antibiofilm. Isolat dievaluasi berdasarkan kemampuan aktivitas antimikroba terhadap enam bakteri patogen dan diikuti dengan penapisan senyawa antibiofilm. Sebanyak 11 dari 65 isolat menunjukkan aktivitas quorum sensing atau quorum quenching, dan hanya terdapat satu isolat yang memiliki aktivitas keduanya. Supernatan kesebelas isolat menunjukkan penghambatan pembentukan biofilm setidaknya terhadap satu patogen dengan metode uji biofilm statis. Karakterisasi senyawa bioaktif dari lima isolat yang terpilih menunjukkan aktivitas senyawa yang berbeda, seperti karbohidrat, protein, dan asam nukleat. Sekuensing gen penyandi 16S rRNA menetapkan kelima isolat tersebut berada dalam dua genus yang berbeda, Vibrio (WK2.4, WK2.6, and WK2.3) dan Pseudomonas (S1.2 dan S1.3). Penelitian ini memberikan wawasan baru terhadap pencarian kandidat bakteri akuatik sebagai agen antibiofilm yang potensial. Abstract Biofilm involvement in chronic infections and on the surface of medical equipment have been considered as public health concern worldwide. Bacterial biofilm is related to antibiotic resistance, making the diseases difficult to treat. An effective control strategy should be implemented, for example, by applying antibiofilm agents. The use of aquatic environment as potential sources of bioactive compounds, including the antibiofilm compounds, is recently of concern. This study aimed to screen and characterize bacteria with antibiofilm activity that were isolated from waterfall and marine environment and obtained from several locations in Indonesia. The isolates were firstly evaluated for their antimicrobial activity against six bacterial pathogens and followed by antibiofilm screening. Eleven out of 65 isolates showed quorum sensing or quorum quenching activity, and one of them showed both activities. Supernatants of 11 isolates inhibited biofilm formation of at least one pathogen by using static biofilm assay. Bioactive compounds characterization of the selected five isolates revealed the presence of different compounds, such as carbohydrates, proteins, and nucleic acids. The 16S rRNA gene sequencing analysis classified five isolates into two different genera, namely Vibrio (WK2.4, WK2.6, and WK2.3) and Pseudomonas (S1.2 and S1.3). The present study provides insights into the discovery of aquatic bacteria candidates as antibiofilm agents.
