Food is everything that comes from biological sources and water, both processed and unprocessed, which is intended as food or drink for human consumption. In addition to being nutritious, food must also be free from hazardous materials in the form of chemical contaminants, pathogenic microbes and other materials. Microbes can contaminate food through water, dust, air, soil, food processing equipment and secretions from the intestines of humans or animals. Yoghurt is the result of milk fermentation with the help of lactic acid bacteria. This product is widely found in the community because of the benefits and nutrients contained in it. To find out the microbial content, both beneficial and not, microbiological tests must be carried out on yogurt drink samples that are sold freely in the community. Bacterial isolation is carried out by the pour cup method on MRSA media. Bacterial isolation is carried out by diluting the yogurt sample to a dilution of 10-6. The sample was then poured 1 ml into a Petri dish containing MRSA media. Then incubation was carried out for 48 hours at a temperature of 360C. The results of bacterial isolation were then counted and identified by observing the morphology of bacterial colonies that grew on MRSA media then continued with the gram staining test and observation of microscopic characteristics using a microscope. In addition, motility and biochemical tests of bacteria were also carried out (catalase test, citrate test, nitrate test, H2S test, MR test, VP test, starch hydrolysis test, Urea test and He test). The results of microbial identification in yogurt drink samples in Situbondo square are Streptococcus thermophilus and Lactobacillus sp. Both of these bacteria are lactic acid bacteria that play a role in the fermentation process and are not pathogenic to humans.

One of the important biological resources in the Indonesian plantation sector is coconut. Coconut trees grow widely in several regencies in Indonesia, including Situbondo Regency. Based on data from the Situbondo Regency Statistics Agency (BPS), coconut plantation production in Situbondo Regency in 2023 reached 4.9 thousand tons. Coconut husks in Situbondo have been considered waste that is sold cheaply to prevent accumulation. Therefore, further processing or utilization is needed to provide greater productive value for coconut husks. Rarely used coconut husk waste can be an alternative to the hard-to-find sawdust media, thereby increasing productivity in mushroom cultivation, especially in the Situbondo region. This study used two types of oyster mushrooms: white oyster mushrooms and brown oyster mushrooms. Each received five treatments with three replications, resulting in a total of 15 white oyster mushroom bags and 15 brown oyster mushroom bags used. The treatment carried out was the addition of coconut fiber with different concentrations to the planting media. The planting medium that has the best influence on mycelium growth, fruit body growth time, fruit body wet weight is P1 (100% wood powder without the addition of coconut shells), while the best fruit cap diameter is obtained from the P4 treatment (75% wood powder + 25% coconut shell powder).

Soil is an ecosystem containing various types of microbes with varying morphological and physiological properties. The number of each microbial group varies greatly, with some consisting of only a few individuals, while others number up to millions per gram of soil. The number of microbes influences the chemical and physical properties of the soil, as well as plant growth. By understanding the number and activity of microbes in a soil, it is possible to determine whether the soil is fertile or not, because a high microbial population indicates an adequate food/energy supply, appropriate temperature, sufficient water availability, and soil ecological conditions that support microbial growth. This study aimed to explore and isolate indigenous anaerobic microbes from the soil of Mount Ringgit, Situbondo, and identify their initial characteristics. This study employed a descriptive exploratory approach with laboratory experimental methods. Soil samples were collected using purposive sampling. The isolation process was carried out using a multilevel dilution technique followed by incubation under anaerobic conditions. The growing colonies were then purified and characterized macroscopically and microscopically. The results of the study showed that two distinct anaerobic bacterial isolates were obtained. Based on characterization, the isolates were identified as Clostridium sp. and Thiobacillus denitrificans. The presence of these two bacteria indicates that the soil of Mount Ringgit, Situbondo, has the potential for anaerobic microbial diversity, which plays a role in the decomposition of organic matter and the transformation of inorganic compounds.
