Background: Medium is a material consisting of a mixture of nutrients which functions as a place to grow microbes. Semi-synthetic media such as PDAs contain sufficient carbohydrates so that they are good for use for fungal growth. This medium is quite a lot needed in the breeding of Candida albicans and Aspergillus niger both in the laboratory. However, the price of this media is quite expensive and limited, while the need is increasing so that alternative media are needed to replace the breeding. Objective: To determine the growth rate of unicellular and multicellular fungi on breadfruit alternative media (Artocarpus altilis) in semi-solid and powder dosage forms. Methods: This study is a descriptive study with a laboratory instrumental approach Results: An alternative medium of tribal composition, dextrose, so that the semi-solid dosage form and powder form could grow Candida albicans and Aspergillus niger well.
背景:培养基是一种由多种营养物质混合而成的材料,是微生物生长的场所。半合成介质如pda含有足够的碳水化合物,因此它们对真菌生长有好处。这种培养基在白色念珠菌和黑曲霉的实验室培养中是非常需要的。然而,该媒介的价格昂贵且有限,而需求不断增加,因此需要替代媒介来替代养殖。目的:测定面包果替代培养基(Artocarpus altilis)半固体和粉末两种剂型下单细胞和多细胞真菌的生长速率。方法:采用实验室仪器方法进行描述性研究。结果:以葡萄糖为替代培养基,使半固体剂型和粉状剂型均能较好地培养白色念珠菌和黑曲霉。

ABSTRACT Tanjung Api Nature Reserve is a headland located in Tomini Bay Ampana District Tojo Una-Una Regency, Central Sulawesi Province. This study aims to obtain local bacteria isolates as antimicrobial producers. The method used in this research is purposive sampling and screening method using "Agar Dua Lapis" (Double Layer Method). Testing antimicrobial potency using the method to make Well Diffusion (well) using three pathogens of microbial tests (S. aureus, E. coli, and C. albicans). In each well hole is given 500 μL of bacterial isolates each and incubated at a temperature of 37 oC for 24 hours and continued for 48 hours. The observed parameter is a clear zone formed around the well. Antimicrobial-producing bacteria screening results. obtained as many as 24 isolates of bacteria. Testing of antimicrobial potency by looking at the resulting inhibitory zone is obtained five isolates namely S2U1, S3U3, S7U3, S9U3, and S10U3 are the highest isolates of the bland zone of 12.25 mm but only against S. aureus, while S9U3 is the best isolate because it is able to inhibit the four test microbes namely S. aureus by 5.50 mm, E. coli 9.25 mm, and C. albicans 5.50 mm.   Keywords:  Exploration of bacteria, antimicrobials, and Nature Reserve

Landu beach is a beach located on Landu Island, Southwest Rote District, Rote Ndao Regency, which is the southernmost district in Indonesia. Sea cucumbers are used by the coastal community of Landu Beach as food and sold to the market as a source of income. So far, it is not scientifically known the types of sea cucumbers and the level of sea cucumber diversity in the coastal waters of Landu. Therefore, this study aims to identify the diversity and abundance of sea cucumbers on Landu Beach, Landu Island, Rote Ndao Regency. This study used a survey method with the sampling technique using the quadratic transect method (quadrant transect method). With 5 transects, each transect consists of 5 plots. The data taken were in the form of sea cucumber species, the number of sea cucumbers per plot, and the state of the substrate per observation plot. The results of the study found 4 types of sea cucumber species in Landu Beach, namely Holothuria scabra, Holothuria arata, Holothuria leucospilota, and Bohadchia marmorata. The abundance of each type of sea cucumber found was Holothuria Scabra with the highest abundance value, namely 2.44 ind / m2 followed by Holothuria Arta (2.16ind / m2), Bohadchia Marmorata (1.92 ind / m2), and Holothuria Leucospilota (1.68 ind. / m2). Bohadchia Marmorata species has a frequency of 1.0 which means this species was found in the research plot seedlings. The next frequency values ​​are Holothuria Scabra (0.72), Holothuria Arta (0.68), and the lowest frequency value is Holothuria Leucospilota (0.60). For the diversity index value according to the Shannon-Wiener index (H ') ranges from 1.37 so it is categorized that Landu Beach has moderate diversity.
兰杜海滩是位于兰杜岛的海滩,位于兰杜岛西南部,是印度尼西亚最南端的地区。海参被兰度海滩的沿海社区用作食物,并作为收入来源出售给市场。到目前为止,对兰杜沿海海域海参的种类和多样性水平还没有科学的认识。因此,本研究旨在确定罗得岛兰度海滩海参的多样性和丰度。本研究采用二次样条法(象限样条法)抽样技术的调查方法。共5个样条,每个样条由5个地块组成。采集的数据以海参种类、每块海参数量和每块观察地块基质状况为形式。研究结果发现兰都海滩有4种海参,分别是Holothuria scabra、Holothuria arata、Holothuria leucospilota和Bohadchia marmorata。各类海参的丰度以Holothuria Scabra最高,为2.44 ind / m2,其次是Holothuria Arta (2.16ind / m2)、Bohadchia Marmorata (1.92 ind / m2)和Holothuria Leucospilota (1.68 ind / m2)。Bohadchia Marmorata种出现频率为1.0,表明该种存在于研究地块幼苗中。频率值次之分别为黄颡鱼(Holothuria Scabra)(0.72)、阿尔塔鱼(Holothuria Arta)(0.68),最低频率值为白颡鱼(Holothuria Leucospilota)(0.60)。根据Shannon-Wiener指数(H’)的多样性指数值在1.37范围内,认为Landu Beach具有中等的多样性。
