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.

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.).

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.
