Abstract

Lichens are organism resulting from symbiosis of algae and fungi. These organisms are often used for monitoring of air quality as bio-indicators. This relates to its ability to respond to the presence of pollutants in the air. Sensitive lichens type, will not be found in locations with polluted air conditions. On the other hand, in locations with polluted environmental conditions, the type of lichen commonly found is tolerant lichen. The response of lichens to environmental conditions can be seen from the lichen body itself which is known as the thallus. This study aims to identify the types of lichen thallus found in the greenbelt area of ​​PT. Semen Indonesia (Persero) Tbk Tuban Factory. Sampling in this study was conducted at 4 locations, namely TLO, GRE, GTI, and VIE. The results showed that the lichens found in this study had thallus with crustose, fructicose, squamulose, and gelatinous types.

Abstract

The growth of home-based batik industry in Tuban is rapidly growing, but the waste management is still very simple. Therefore, toxicity tests of the liquid waste generated by the batik industry are needed. This study aims to determine the changes in the morphology of the gills of catfish (Clarias sp.) exposed to toxins in the form of liquid dye waste from the batik industry. This is an experimental study, by adding liquid dye waste from the batik industry with different concentrations in an aquarium containing catfish. Each aquarium consists of five catfish. The concentrations used are 0% (control), 10%, 25%, and 50% for 48 hours. The morphological structure observed is the change in color of the gills of the catfish. The results of the study were analyzed using qualitative descriptive methods. The results showed that there was a difference in the color of the gills of catfish exposed to liquid dye waste from the batik industry. Catfish exposed to liquid dye waste from the batik industry showed gills that were paler and blacker in color, both at concentrations of 10%, 25%, and 50% compared to the control group (concentration 0%) that was not exposed to liquid dye waste from the batik industry.

Abstract

Food safety is the main demand of consumers. Food quality and safety must be ensured to be free from pathogenic materials and safe for consumption. One of the pathogenic bacteria found as contaminants in broiler chicken meat is the Escericia coli. Broiler meat products that are accepted and that will be consumed by the community, they must meet the specified requirements and be proven by a certificate of test results from a recognized institution and based on ISO 17025. One of the testing agencies that has been accredited by the Komite Akreditasi Nasional (KAN), namely the UPTD Laboratorium Kesehatan Hewan Dinas Peternakan Provinsi Jawa Timur Livestock Service, provides community services in laboratory examinations for testing microbial contamination in animal products (meat, milk and eggs) with quality reference standards for microbial contamination limits according to SNI 7388: 2009. The method used in this study is to use the MPN method. This study used 2 samples of broiler chicken meat from PT. Trijaya Lestari Food. The MNP method is a method used to determine the calculation and estimate the amount of contamination of Escherichia coli bacteria contained in broiler chicken meat samples. The result obtained from this study is that the number of positive tubes shows the MPN value as the amount of Escherichia coli per ml / per g. For dilutions 10ˉ¹, 10ˉ² and 10ˉ³ are valued at 0 and if added up the value is <3.0 which indicates that broiler chicken meat samples are below the maximum contamination limit of the number of Escerichia coli bacteria based on SNI 01-3924-2009.

Abstract

Ecoenzymes are active substances that can accelerate the degradation process of waste and improve the quality of the environment. The benefits of ecoenzymes for the environment, particularly in agriculture as fertilizer, and in households as a germ and bacteria killer are very good. It is hoped that ecoenzymes can neutralize batik waste, which is toxic to aquatic environments. This study aims to evaluate the effectiveness of ecoenzymes on the survival rate of catfish (Clarias sp.) in media contaminated with batik waste. The method used is an experiment using three concentrations of ecoenzymes and measuring the sustainability of catfish life at each concentration. Based on the results of the research, catfish that were exposed to batik waste and added with ecoenzymes with concentrations of 0% and 10% showed that the catfish could not survive. This shows that ecoenzymes have not yet been proven to increase the effectiveness in neutralizing batik waste against the survival rate of catfish (Clarias sp.).

Abstract

Observation of leaves, especially the epidermis, is often the focus of research because this part is directly exposed to the environment, so changes that occur in this part can indicate changes in the plant's metabolism. Observation of leaf skin requires preparation in advance, especially in observing wet preparations. There are various methods of leaf skin sample preparation including the printing method and leaf paradermal slices. The purpose of this study was to compare leaf preparations with preparations using the printing method and paradermal slices carried out by students of the Biology at PGRI Ronggolawe University in the Plant Anatomy Practicum course. Data in the form of preparations of leaves Morinda citrifolia and Solanum melongen were observed using an electric microscope with a magnification of 400 times, while Ixora sp. leaves were observed using a light microscope with a magnification of 400 times. The results of the study can be concluded that the printing and paradermal incision methods are optimal for the purpose of observing different leaf characters. The optimal printing method is used on leaves that have little or no trichomes and is very good for observing stomatal openings. While the paradermal slice method is good for use on leaves that have trichomes or not, the use of this method requires good practical skills, besides this method cannot represent leaf stomatal openings at the time of observation because the stomata tend to close.

Abstract

Plastic has a fairly wide distribution in human life. The use of microplastics is very difficult to avoid because it has reduced various human activities. The use of plastics on a large and wide scale raises a problem for the environment and ecosytem through the degradation of plastics into microplastics. Microplastics have the potential to pose a threat to the environment and organisms, especially in water areas. Their small size allows microplastics to be ingested by zooplankton up to a higher trophic level. Damas Beach is one of the marine tourism destinations in the Prigi bay area with a potential fishery sector in East Java. The high activity of tourism and fishing causes Damas beach to be potentially polluted by microplastics. This study aims to determine the type of plastic polymer in the digestive tract of lisong tuna obtained in the Damas beach area, Prigi Bay, Treanggalek Regency, East Java. This study used a purposive sampling method with two repetitions. Types of microplastic polymers were analyzed using FTIR. The results of the analysis showed that the types of plastic polymers found in the digestive tract of lisong tuna include High Density Polyethylene (HDPE), Polyvinyl chloride (PVC), nylon (polyamide, Polyethylene Terephthalate (PET), Polypropylene (PP), and Polystyrene (PS).
