Abstract

Situ Cilodong is located in Kalibaru, Cilodong, Depok. Situ Cilodong served as a beautiful, strategic area and thus served as a local water tourism. However, the presence of a human activity causes it to contain household wastes and other fillings that leak into the body of the water. The study was intended to determine the quality of the water and was held by storet methods. Storets method work by comparing data on water quality with water quality adjusted to it in order to determine water quality status. The parameters used in this study are the physical parameters in the form of temperature and brightness, also chemical in the form of pH and DO, all parameters was measure insitu in the morning. We also do identyfication of plankton. Data retrieval times occurred periodically each week of November 2021. Based on its designation, Situ Cilodong is included in class 2. The sampling station point being used is at the inlet station, center and outlet. The result of research is that the waters at Situ Cilodong was classified as a light polluted lake based on stroret's methods score on the inlet -10 station, -8 and -10 outlets. The most frequently identified type of planton species is from the phytoplanton group.

Abstract

Sanggabuana Mountain is a mountain located within the territory of Karawang Regency. Administratively, the mountain is situated in Karawang Regency, Tegalwaru District, West Java. The height of the mountain is 1,291 meters above sea level (MDPL) and is the highest and only mountain in Karawang. The area has a high biodiversity, making it highly likely to find many macrofungi, especially macrofungi. This research was conducted to determine the diversity of macrofungi in the Sanggabuana Mountain area of Karawang Regency, Tegalwaru District, West Java. The type of research is exploratory and descriptive research, conducted on three observation routes; Route A (Cigentis), Route B (local plantations), and Route C (Kejayaan). The research results obtained a total of 23 species from 17 genera of macrofungi across the three observation routes, with the species diversity index in all three routes falling into the moderate diversity category. The highest encounter frequency of macrofungi on Route B was Ganoderma applanatum (23%), on Route A was Trametes sp (19%), and on Route C was Microporus xanthopus, Xylaria sp, and Inonotus sp (10%). The species dominance index on Route A falls into the high dominance category, while on Route B and C, it falls into the low dominance category.
